The track slab manufacturing is completed in sequence through the various production stations on an assembly line in accordance with a preset process flow with a certain cycle through fully intelligent and automatic control. The production line is composed of the stations ranging from the track slab mold cleaning station 1 to the track slab water-curing station 16. All data transmission, storage and actions are centrally controlled by the central control subsystem. it realizes the factory and automatic prefabrication of track slabs, thereby maximizing the manufacturing efficiency and prefabrication precision of track slabs, saving a lot of manpower and material resources, and increasing the reuse rate of equipment.

The central control subsystem includes a data server, a plan management module, a production scan code service module, a transfer control module, an automatic station central control module, a production data management module and a video monitoring module. The plan management module, the production scan code module, the transfer control module, the automatic station central control module, the production data management module and the video monitoring module are connected with the data server for communication.

Specifically, the plan management module is used to formulate a track slab production plan and manage a track slab production schedule.

The plan management module formulates the production plan of each type of track slab on monthly, weekly and daily bases, and updates completed data in real time. Specific data includes monthly plan, monthly completion progress, weekly plan, weekly completed progress, daily plan and daily completion progress. The production plan and completion progress can be made into statistical reports and pie charts.

Specifically, the production scan code service module is used to record and manage data of the track slab mold 1915 and/or the track slab 1914 entering each station, such as electronic code information, time of entering each station, time of leaving each station, and setting information, activation status and fault information of code scanners at each station.

Each track slab mold is provided with a mold chip, and each mold chip is provided with a unique electronic code. Each reinforcement cage is provided with a track slab chip, and each track slab chip is provided with a unique electronic code. Each station is provided with a code scanner. The code scanner is used to identify the electronic codes of mold chips and track slab chips, and send the electronic code information, the time information of track slab molds 1915

-14- and/or track slabs 1914 entering the station, and the time information of the track slab molds 1915 and/or the track slabs 1914 leaving the station to a station scanning sub-server.

it works as follows: {1) The mold chip and the track slab chip are activated to enter the electronic code of the mold chip and the electronic code of the track slab chip into the station scanning sub-server.

{2) When the track slab mold 1915 is transferred to each station before the reinforcement cage mounting station 5, the code scanner of each station recognizes the mold chip on the track slab mold 1915, and sends the electronic code information of the mold chip, the time information of the track slab mold 1915 entering the station and the time information of the track slab mold 1915 leaving the station to the station scanning sub-server.

(3) When the track slab mold 1915 is transferred to the reinforcement cage mounting station 5, the reinforcement cage mounting station 5 places the reinforcement cage with the track slab chip in the cavity of the track slab mold 1915. The code scanner of the reinforcement cage mounting station 5 recognizes the mold chip on the track slab mold 1915 and/or the track slab chip on the reinforcement cage, and sends the electronic code information of the mold chip and/or the electronic code information of the track slab chip, the time information of the track slab mold 1915 entering the reinforcement cage mounting station 5 and the time information of the track slab mold 1915 leaving the reinforcement cage mounting station 5 to the station scanning sub-server.

{4} When the track slab mold 1915 is transferred to stations between the tensioning rod screwing station 6 and the reinforcement cage insulation detection station 8, the code scanner at each station recognizes the mold chip on the track slab mold 1915 and/or the track slab chip on the reinforcement cage, and sends the electronic code information of the mold chip and/or the electronic code information of the track slab chip, the time information of the track slab mold 1915 entering the station and the time information of the track slab mold 1915 leaving the station to the station code scanning sub-server.

(5) When the track slab mold 1915 is transferred to the track slab pouring station 9, the track slab pouring station 9 pours concrete into the cavity of the track slab mold 1915 to form the track slab 1914. The track slab mold 1915 and the track slab 1914 in its cavity form a molded track slab 1913. The code scanner of the track slab pouring station 9 recognizes the mold chip on the track slab mold 1915 and/or the track slab chip on the track slab 1913, and sends the electronic code information of the mold chip and/or the electronic code information of the track slab chip, the time information of the track slab mold 1915 entering the track slab

-15- pouring station 9 and the time information of the molded track slab 1913 leaving the reinforcement cage mounting station 9 to the station scanning sub-server. (6) When the molded track slab 1913 is transferred to the steam curing station 10 and the pre- stressed relaxing station 11, the code scanner of each station recognizes the mold chip on the track slab mold 1915 and/or the track slab chip on the track slab 1913, and sends the electronic code information of the mold chip and/or the electronic code information of the track slab chip, the time information of the molded track slab 1913 entering the station and the time information of the molded track slab 1913 leaving the station to the station scanner server.

(7) When the molded track slab 1913 is transferred to the track slab demolding station 12, the track slab demolding station 12 separates the track slab 1914 from the track slab mold 1915. The code scanner of the track slab demolding station 12 recognizes the mold chip on the track slab mold 1915 and/or the track slab chip on the track slab 1913, and sends the electronic code information of the mold chip and/or the electronic code information of the track slab chip, the time information of the molded track slab 1913 entering the track slab demolding station 12 and the time information of the track slab 1914 leaving the track slab demolding station 12 to the station scan code sub-server. {8) When the track slab 1914 is transferred to the track slab turning station 13 and each station after the track slab turning station 13, the code scanner of each station recognizes the track slab chip on the track slab 1914, and sends the electronic code information of the track slab chip, the time information of the track slab 1914 entering each station and the time information of the track slab 1914 leaving each station to the station scanning sub-server. Specifically, the automatic transfer control module is used to control the track slab mold 1915 and/or the track slab 1914 to be transferred on the rails or to be correspondingly transferred to each station. The automatic transfer control module is further used to display the electronic code information of the track slab mold 1915 and/or the track slab 1914 in real time, and control the start, end and emergency stop of the transfer. The main line stations (the station 1 to the station 8 and the station 11 to the station 18), the track slab pouring station 9, the steam curing station 10 and each mobile cart are each provided with a transfer programmable logic controller (PLC). The PLC communicates with the automatic transfer control module. The automatic transfer control module controls the translation trolleys carrying the track slab mold 1915 and/or the track slab 1914 to be transferred on the rails or to be correspondingly transferred to each station through the PLC.

-16- Specifically, the automatic station central control module is used to control the opening and closing of each station and acquire various process parameters in real time.

Except for the pre-stressed tensioning station 7 and the pre-stressed relaxing station 11, each station is provided with a station PLC.

The station PLC communicates with the automatic station central control module.

The automatic station central control module controls the corresponding station through the station PLC to set process parameters to process the track slab and acquire various process parameters in real time.

For example, in the reinforcement cage insulation detection station 8, the automatic station central control module can set detection parameters, and the station PLC of the reinforcement cage insulation detection station 8 can remotely control the station to perform insulation detection on the track slab mold 1915. The automatic station central control module can also display detection data and detection results in real time, and prompts for unqualified data and fault alarms.

In the track slab pouring station 9, the automatic station central control module can set process parameters such as the vibration frequency, amplitude and vibration time of a vibration device in the track slab pouring station 9, and controls the vibration device through the station PLC in the track slab pouring station 9. In the steam curing station 10, the automatic station central control module can set steam curing parameters of the track slab and can remotely control the start and stop of the steam curing station 10. A sensor provided at the steam curing station 10 acquires steam curing data at the steam curing station 10 and sends the data to the automatic station central control module.

In the track slab water-curing station 16, the automatic station central control module can set water-curing parameters.

A sensor provided at the track slab water-curing station 16 acquires the temperature and pH in a maintenance tank at the track slab water-curing station 16, and sends the data to the automatic station central control module.

The pre-stressed tensioning station 7 and the pre-stressed relaxing station 11 are provided with a station PLC and a computer, which communicate with the automatic station central control module in sequence.

In each station, the automatic station central control module controls the station PLC through the computer so as to control the corresponding state to process the track slab, and the computer is further used to acquire real-time data and reports.

Specifically, the plan management module, the production scan code service module, the transfer control module and the automatic station central control module send various data

-17- information and time information to the data server, and the data server stores the data information and time information. Specifically, the production data management module is used to search for various data in the data server, and summarize and sort out the electronic code information of the track slab and the operating time, data, curves and reports of each station.

For example, the production data management module can display the tensioning data, tensioning curves and tensioning reports of the pre-stressed tensioning station 7, the relaxing data and relaxing curves of the pre-stressed relaxing station 11, the steam curing data of the steam curing station 10 (the temperature of the acquisition point and the ambient temperature of each steam curing channel}, and water curing data and change curves of the track slab water-curing station 16. Specifically, the video monitoring system is used to monitor the video monitoring and video replay of a track slab production workshop. Multiple cameras are provided at key monitoring points of the track slab production workshop.

The cameras are electrically connected with the video monitoring system. The camera system monitors the track slab production workshop in real time and sends video information to the video monitoring system. The video monitoring system backs up the video information. The video monitoring system is connected with a local area network (LAN), such that all authorized users in the LAN can monitor the track slab production workshop through the network and replay the video. The multiple cameras can also be connected with a large splicing screen in a central monitoring room, which is convenient for operators to monitor the production status of the track slab production workshop in real time. Further, referring to FIG. 4, the station 1, namely the track slab mold cleaning station is described below. The mold cleaning station includes a cleaning robot 11, a roller brush assembly 12, horizontal rails 13, a residue collecting device and a dust removal system. The cleaning robot 11 is used to drive the roller brush assembly 12 to move up and down in a vertical direction, and to drive the roller brush assembly 12 to move left and right along the horizontal rails 13. The roller brush assembly 12 is used to clean cement residue on the track slab molds 1915. The residue collecting device is fixed on the cleaning robot 11 and is used to collect cement residue missed by the roller brush assembly 12. The dust removal system includes a dust hood provided above the cleaning robot 11, the roller brush assembly 12, the horizontal rails 13 and the residue

-18- collecting device. The dust hood is connected with a vacuum cleaner to remove dust generated when the track slab mold 1915 is cleaned. The roller brush assembly 12 has four types, a large roller brush assembly, a special-shaped roller brush assembly, a disc-shaped roller brush assembly and a cylindrical roller brush assembly. The large roller brush assembly is used to clean an overall surface of the track slab mold 1915, the special-shaped roller brush assembly is used to clean a support platform, the disc-shaped roller brush assembly is used to clean a blind area of a large brush roller, and the cylindrical roller brush assembly is used to clean the first side molds 19152, the second side molds 193 and a pouring drum.

The roller brush assembly 12 includes a roller brush and bristles, and the bristles are fixed on the roller brush. When the roller brush assembly 12 cleans the track slab mold 1915, the roller brush rotates at a high speed, and the bristles clean the cement residue on the track slab mold

1915.

The bristles are preferably DuPont abrasive filaments loaded with silicon carbide with a length of 80 mm and an elastic coefficient of 0.5. The existing bristles are generally made of steel wires, The bristles made of steel wire are in line contact with the track slab mold 1915 to form a cylindrical contact surface. In contrast, the elastic DuPont silicon carbide abrasive wires are in surface contact with the track slab mold 1915 to form an elastic deformation surface. Therefore, the bristles made of DuPont abrasive filaments loaded with silicon carbide increase the contact area with the track slab mold 1915, thereby improving the cleaning ability. In addition, the elastic DuPont silicon carbide abrasive wires are not easy to damage, and the working life of the roller brush using the bristles made of DuPont silicon carbide abrasive wires is 1.2-1.3 times that of the roller brush using the bristles made of steel wires.

Referring to FIG. 5, the station 2, namely the release agent spraying station is described below.

The release agent spraying station 2 includes a spraying frame 21, nozzles 22, a release agent container and a pneumatic diaphragm pump. The release agent container is used to hold a release agent, and the release agent container is connected with the pneumatic diaphragm pump through a liquid inlet tube. The pneumatic diaphragm pump is connected with multiple nozzles 22 through a liquid outlet tube. The pneumatic diaphragm pump is used to control the release agent in the release agent container to enter the nozzles 22 through the liquid inlet tube and the liquid outlet tube in sequence. The nozzles 22 are able to move horizontally and vertically relative to the spraying frame 21 to spray the release agent to the track slab mold

1915. The nozzles 22 are provided with a control valve, which is manually adjustable.

-19- Specifically, a pneumatic agitator and a filtering device are arranged in the release agent container. The pneumatic agitator is used to agitate the release agent to make the release agent evenly mixed. The filtering device is used to filter the release agent to avoid clogging of the nozzles 22 with sediment.

The filtering device is an acid-resistant nylon filter cloth with a uniform thickness of filter aid on a surface. The filter aid is used to filter tiny particles. Specifically, the nozzles 22 spray the filter aid to the track slab mold 1915 in a circular path to adapt to the structure of the track slab mold 1915, a drying time of the release agent and a spraying position.

Further, the release agent spraying station 2 includes an oil mist suction device for collecting the release agent after atomization and transforming it into a liquid state for recycling. Further, a required amount of the release agent is calculated as follows: V=(axb+2x({a+b)xh)xd where, a is a length of the mold cavity; b is a width of the mold cavity; h is a depth of the mold cavity; and d is a spray thickness of the release agent.

Take a 5600 mold cart as an example, a is 5,600 mm, b is 2,500 mm, h is 190 mm and d is 0.02 mm, then: V5600=(axb+2x(a+b)xh)xd ={5600x2500+2x(5600+2500)x190}x0.02=0.341561=0.35L Further, the nozzles 22 in the release agent spraying station 2 are able to move horizontally, such that a covering surface of the release agent sprayed extends beyond the cavity of the track slab mold 1915 and is caused to fall and adhere to a sidewall of the track slab mold 1915. if manual spraying is used, a required amount of the release agent for the track slab mold 1915 is calculated as follows: Take a 5600 mold cart as an example, a is 5,600 mm, b is 2,500 mm, h is 190 mm and d is 0.02 mm, then the overall required amount of the release agent for the track slab mold 1915 is: Vseoo={axb+2x({a+b)xh)xd =(5600%x2500+2x(5600+2500)x190)x0.02=0.34156L=0.35L A required amount of the release agent for the sidewall of the track slab mold 1915 is calculated as follows: Vssoosidewati=2 (a+b )xhxd=2x(5600+2500)x190x0.02=0.06156L~0.062L The ratio of the required amount of the release agent for the sidewall of the track slab mold 1915 to the overall required amount of the release agent for the track slab mold 1915 is

-20- Vsgoosidewati/ Vs609=0.062/0.35=0.1771=17.71%, indicating that the sprayed surface reaches more than 80%. Station 3: Embedded casing mounting station The embedded casing mounting station 3 includes three parts, namely a jacking and positioning subsystem, a casing mounting robot subsystem and a circulating pallet feeding subsystem. The jacking and positioning subsystem is used to jack and position the track slab mold 1915. The casing mounting robot subsystem includes an embedded casing mounting robot and an execution gripper. The embedded casing mounting robot is a high-precision three-axis truss robot. The circulating pallet feeding subsystem is used to transport a casing.

Its working principle is as follows. After a mold is transferred to the embedded casing mounting station 3, the central control subsystem sends a work instruction to the embedded casing mounting robot. The jacking and positioning subsystem performs jacking and positioning of the track slab mold 1915 to realize the precise positioning of the track slab mold

1915. A visual position detection system is used to detect whether there is a mold positioning deviation and compensate the positioning deviation, if any. The embedded casing mounting robot grabs a casing assembly by the execution gripper at an end, and places the casing assembly on a positioning tensioning sleeve of the mold cart. Subsequently, the embedded casing mounting robot compresses the casing on the positioning tensioning sleeve of the mold cart through an air hammer. A pressure detection sensor quantitatively records the striking force of the air hammer and monitors an abnormal state. After the mounting of the casing on the support platform is completed, the embedded casing mounting robot returns to its original position, and the circulating pallet feeding subsystem replaces a casing pallet for holding the casing, ready for the next operation.

Station 4: Reinforcement cage binding station The reinforcement cage binding station 4 includes a binding platform. Multiple transmission devices are arranged under the binding platform. A T-shaped track wheel on the transmission devices is matched with a channel steel track on the binding platform. A blocking device is provided in front of the binding platform, and a lifting device is provided behind the binding platform. A pushing device is provided under the lifting device.

The working principle of this station is as follows. The transmission devices realize the movement of the binding platform in an X-axis direction. After the binding platform moves to a working area, the blocking device blocks the binding platform and restricts it from continuing to move. The pushing device on the other side of the binding platform pushes the binding platform such that it is completely positioned in the X-axis direction. The positioning and

-21- binding of steel bars are carried out on the binding platform.

When the binding of the reinforcement cage is completed, the blocking device releases the binding platform.

Driven by the motor, the entire binding platform and the binded reinforcement cage are pushed to a three-dimensional storehouse for standby.

Station 5: Reinforcement cage mounting station The reinforcement cage mounting station 5 includes a binding mold, an automatic mold transmission device, a mold conveying device, a reinforcement cage conveying device and a mold positioning device.

The working principle of this station is as follows.

After the binding is completed, the binding mold carries the reinforcement cage and is transferred to a grabbing position through the automatic mold transmission device.

The reinforcement cage conveying device grabs the reinforcement cage, and the mold positioning device accurately conveys the reinforcement cage to the track slab mold 1915 to place the reinforcement cage into the mold.

The steel bars in the reinforcement cage include grounding bars and spiral bars.

The welding of the grounding bars and the binding of the steel bars are completed with high-precision molds, and the production of the spiral bars is completed with automatic equipment to improve the processing accuracy and realize fully automated operation.

Station 6: Tensioning rod screwing station (FIG. 6) The tensioning rod screwing station 6 includes a screwing support frame 61, two first side mold screwing subsystems 62 and two second side mold screwing subsystems 63. The two first side mold screwing subsystems 62 are respectively located at front and rear sides of the screwing support frame 61, and are used to allow multiple first tensioning rods 191541 to pass through multiple first through holes 191521 and connect to steel bars on front and rear sides of the reinforcement cage.

The two second side mold screwing subsystems 63 are respectively located on left and right sides of the screwing support frame 61, and are used to allow multiple second tensioning rods 191542 to respectively pass through multiple second through holes 191531 and connect to steel bars on left and right sides of the reinforcement cage.

The working principle of this station is as follows.

The two first side mold screwing subsystems 62 synchronously screw and connect the multiple first tensioning rods 191541 to the steel bars located on the front and rear sides of the reinforcement cage.

Alternatively, one first side mold screwing subsystem 62 sleeves the first tensioning rods 191541 on the steel bars and then it remains fixed.

The other first side mold screwing subsystem 62 performs screwing operations to simultaneously connect the multiple first tensioning rods 191541 to the steel bars located

-22- on the front and back sides of the reinforcement cage.

This method avoids the synchronous screwing of the two first side mold screwing subsystems 62 from causing follow-up lag and position synchronization errors.

Similarly, the two second side mold screwing subsystems 63 synchronously screw and connect the multiple second tensioning rods 191542 to the steel bars on the left and right sides of the reinforcement cage.

Alternatively, one second side mold screwing subsystem 63 sleeves the second tensioning rods 191542 on the steel bars and then it remains fixed.

The other second side mold screwing subsystem 63 performs screwing operations to simultaneously connect the multiple second tensioning rods 191542 to the steel bars located on the left and right sides of the reinforcement cage.

This method avoids the synchronous screwing of the two second side mold screwing subsystems 63 from causing follow-up lag and position synchronization errors.

Station 7: Pre-stressed tensioning station (FIGS. 7 to 9) The pre-stressed tensioning station 7 includes a tensioning mechanism, tensioning connection detectors 74, tensioning disconnection detectors 75, a tensioning mold positioning detector, tensioning displacement detectors 77 and an integral tensioning support frame for supporting the tensioning mechanism.

The tensioning mechanism includes a tensioning support 71. A front side of the tensioning support 71 is provided with a first tensioning beam 721, and left and right sides of the tensioning support 71 are respectively provided with second tensioning beams 722. Multiple first tensioning assemblies 731 are spaced apart in a length direction of the first tensioning beam 721. Multiple second tensioning assemblies 732 are spaced apart in a length direction of each of the second tensioning beams 722, A first driving cylinder is provided on the integral tensioning support frame.

The first driving cylinder is used to drive the tensioning support 71 to move up and down, such that the tensioning support 71 drives the first tensioning beam 721, the first tensioning assemblies 731, the second tensioning beams 722 and the second tensioning assemblies 732 to move up and down synchronously.

The tensioning support 71 is provided with a second driving cylinderon a front side.

The second driving cylinder is used to drive the first tensioning beam 721 to move horizontally in front and rear directions of the tensioning support 71. Thus, the first tensioning beam 721 drives the first tensioning assemblies 731 to move horizontally in the front and rear directions of the tensioning support 71, such that the first tensioning assemblies 731 are connected with or disconnected from the first tensioning rods 191541. The left and right sides of the tensioning support 71 are respectively provided with third driving cylinders.

The third driving cylinders are used to drive the second tensioning beams 722 to move horizontally in

-23- left and right directions of the tensioning support 71. Thus, the second tensioning beams 722 drive the second tensioning assemblies 732 to move horizontally in the left and right directions of the tensioning support 71, such that the second tensioning assemblies 732 are connected with or disconnected from the second tensioning rods 191542. The first tensioning assemblies 731 are connected with the first tensioning rods 191541 to tension the first tensioning rods

191541. The second tensioning assemblies 732 are connected with the second tensioning rods 191542 to tension the second tensioning rods 191542, Multiple tensioning displacement detectors 77 are respectively located on the front, left and right sides of the tensioning support 71. They are used to detect a horizontal movement distance of the first tensioning beam 721 in the front and rear directions and a movement distance of the second tensioning beams 722 in the left and right directions, so as to improve the displacement accuracy of the first tensioning assemblies 731 and the second tensioning assemblies 732. The tensioning connection detectors 74 include first tensioning connection detectors and second tensioning connection detectors. The first tensioning assemblies 731 are each provided with one first tensioning connection detector, and the second tensioning assemblies 732 are each provided with one second tensioning connection detector. The first tensioning connection detectors are used to detect whether the first tensioning assemblies 731 are connected with the first tensioning rods 191541. The second tensioning connection detectors are used to detect whether the second tensioning assemblies 732 are connected with the second tensioning rods 191542, so as to improve the mounting accuracy and reliability of the tensioning rods. The tensioning disconnection detectors 75 include a first tensioning disconnection detector and two second tensioning disconnection detectors. The first tensioning disconnection detector is located on the front side of the tensioning support 71, and the two second tensioning disconnection detectors are located on the left and right sides of the tensioning support 71, respectively. After the tension is completed, the first tensioning disconnection detector is used to detect whether the first tensioning assemblies 731 are disconnected from the first tensioning rods 191541, and the second tensioning disconnection detectors are used to detect whether the second tensioning assemblies 732 disconnected from the second tensioning rods 191542. The disconnection detectors can prevent tensioning assemblies not disconnected from the tensioning rods from rising to damage the tensioning rods and the track slab mold 1915.

-24- The tensioning mold positioning detector is located at a bottom of the tensioning support 71.

When the tensioning support 71 moves down to be docked with the track slab mold 1915, the mold positioning detector is used to detect whether a tensioning positioning pin at the bottom of the tensioning support 71 fits with a positioning hole on the track slab mold 1915. After the tensioning positioning pin is attached to the positioning hole, the tensioning support 71 stops moving down.

Preferably, the tensioning connection detectors 74 are detection switches. The tensioning disconnection detectors 75 are active infrared intrusion detectors. The tensioning mold positioning detector is a proximity switch.

Further, the first tensioning assemblies 731 each include a sleeve 7331, a connector 7332, a jack 7334, a connector lifting drive member 7333, a jack force detector 7335 and a connector lifting detector assembly.

The sleeve 7331 is used to connect a threaded section at an end of a corresponding first tensioning rod 191541. The connector 7332 is used to connect a rod body 73361 of the first tensioning rod 191541. The jack 7334 is used for tensioning and screwing the threaded section at the end of the first tensioning rod 191541. The jack force detector 7335 is used to detect a displacement of a driving end of the jack 7334. When the displacement exceeds a normal value, the jack force detector 7335 issues an alarm to prevent the jack 7334 from failing to apply force to the first tensioning rod 191541 even if its driving end moves beyond the normal value. The jack force detector 7335 is preferably a displacement sensor. The connector lifting drive member 7333 is used to drive the connector 7332 to move up and down. A connector lifting detector is used to detect the position of the connector 7332 moving up and down to ensure the position accuracy.

The connector lifting detector assembly includes a rod body 73361 fixed to the connector 7332, an upper limiting member 73362, a lower limiting member 73363 and a connector lifting detector. The lower limiting member 73363 is located below the upper limiting member

73362. When the connector lifting drive member 7333 drives the connector 7332 to move up and down, it drives the rod body 73361 to move up and down synchronously. The connector lifting detector is used to detect whether the rod body 73361 moves up to the upper limiting member 73362 or moves down to the lower limiting member 73363 so as to limit the distance that the connector 7332 moves up and down.

The structure and working principle of the second tensioning assemblies 732 are the same as the first tensioning assemblies 731. Station 8: Reinforcement cage insulation detection station (FIGS. 10 to 20)

-25- A longitudinal direction of this station is a left-right direction shown in FIG. 10, and a transverse direction of this station is a front-rear direction shown in FIG. 10. The reinforcement cage insulation detection station 8 includes a transverse detection mechanism 81, transverse lifting mechanisms 82 driving the transverse detection mechanism 81to linearly lift, at least one longitudinal detection mechanism 83 and longitudinal lifting mechanisms 84 driving the longitudinal detection mechanism 83 to linearly lift.

There are three specifications of common track slabs, namely 5600, 4925 and 4856. As the three specifications of track slabs have the same width, only one transverse detection mechanism 81 in the width direction can meet the detection needs of the three types of track slabs.

In practical applications, in order to meet the detection requirements of the three different specifications of track slabs, three longitudinal detection mechanisms 83 are arranged in the longitudinal direction.

Of course, two, four or more longitudinal detection mechanisms 83 may be provided according to actual needs. it should be noted that the three longitudinal detection mechanisms 83 have the same structure, and the difference is only that the distances between multiple longitudinal contact devices 833 on the longitudinal detection mechanism 83 are different.

The longitudinal detection mechanism 83 includes a longitudinal beam 831, a longitudinal swinging drive device 832 and multiple longitudinal contact devices 833 spaced apart along a length of the longitudinal beam 831. The longitudinal swinging drive device 832 is provided on the longitudinal beam 831, and is used to drive longitudinal contacts of the multiple longitudinal contact devices 833 to swing simultaneously so as to contact transverse steel bars at detection points of steel bars 1916. The transverse detection mechanism 81 includes a transverse beam 811, a transverse swinging drive device 812 and multiple transverse contact devices 813 spaced apart along a length of the transverse beam 811. The transverse swinging drive device 812 is provided on the transverse beam 811, and is used to drive transverse contacts of the multiple transverse contact devices 813 to swing simultaneously so as to contact longitudinal steel bars at detection points of the steel bars 1916. in practical applications, the longitudinal beam 831 and the transverse beam 811 are arranged crosswise.

The longitudinal contacts of the longitudinal contact devices 833 on the longitudinal beam 831 are in contact with each transverse steel bar, and the transverse contacts of the transverse contact devices 813 on the transverse beam 811 are in contact with each longitudinal steel bar.

In this embodiment, a crossing angle of the longitudinal beam 831 and the transverse beam 811 is not limited.

In this embodiment, in order to reduce the space of the longitudinal beam 831 and the transverse

-26- beam 811 and the length of the longitudinal beam 831 and the transverse beam 811 to reduce production costs, the longitudinal beam 831 and the transverse beam 811 are arranged vertically. This embodiment provides a steel bar insulation performance detection device. Through the at least one longitudinal detection mechanism 83, the insulation performance detection device can detect different specifications of steel bars 1916, which improves the applicability of the insulation performance detection device. Through the lifting assembly, the insulation performance detection device can detect the detection points of different layers of the steel bars 1916. Through the cooperation of the longitudinal detection mechanism 83 and the transverse detection mechanism 81, the insulation performance detection device can simultaneously detect the detection points of the same layer of the steel bars 1916, which improves the detection efficiency. Since the swinging drive assemblies are provided in the longitudinal detection mechanism 83 and the transverse detection mechanism 81, the contact devices can swing simultaneously to contact the steel bars on two sides of the detection points of the steel bars 1916, which improves the detection accuracy and further improves the detection efficiency. Specifically, the fongitudinal swinging drive device 832 includes a first drive plate 8321, a first drive member 8322 and a first mounting frame 8323. The first drive member 8322 is provided on the longitudinal beam 831 through the first mounting frame 8323. The first drive plate 8321 is provided on a sidewall of the longitudinal beam 831 and is slidably connected with the sidewall of the longitudinal beam 831. The first drive plate 8321 is connected with multiple longitudinal contact devices 833. The first drive member 8322 pushes the first drive plate 8321 to move along the length of the longitudinal beam 831, such that the first drive plate 8321 drives the longitudinal contacts of the multiple longitudinal contact devices 833 to simultaneously swing to contact the transverse steel bars at the detection points of the steel bars 1916. Similarly, the transverse swinging drive device 812 includes a second drive plate 8121, a second drive member 8122 and a second mounting frame 8123. The second drive member 8122 is provided on the transverse beam 811 through the second mounting frame

8123. The second drive plate 8121 is provided on a sidewall of the transverse beam 811 and is slidably connected with the transverse beam 811. The second drive plate 8121 is connected with multiple transverse contact devices 813. The second drive member 8122 pushes the second drive plate 8121 to move along the length direction of the transverse beam 811, such that the second drive plate 8121 drives the transverse contacts of the multiple transverse

-27- contact devices 813 to simultaneously swing to contact the longitudinal steel bars at the detection points of the steel bars 1916. The longitudinal contact devices 833 each include a first swinging plate 8331, a first connecting flange 8332 and a first detection rod 8333 connected with the first connecting flange 8332. A free end of the first detection rod 8333 defines a longitudinal contact.

The first swinging plate 8331 and the first connecting flange 8332 are respectively arranged on two sides of the longitudinal beam 831. The first swinging plate 8331 and the first connecting flange 8332 are connected by a pin shaft.

Multiple first swinging plates 8331 are connected with the first drive plate 8321, such that the movement of the first drive plate 8321 drives the multiple first swinging plates 8331 to deflect.

Thus, first detection rods 8333 connected with first connecting flanges 8332 swing simultaneously to contact the transverse steel bars at the detection points of the steel bars 1916. Preferably, the transverse contact devices 813 each include a second swinging plate 8131, a second connecting flange 8132 and a second detection rod 8133 connected with the second connecting flange 8132. A free end of the second detection rod 8133 defines a transverse contact.

The second swinging plate 8131 and the second connecting flange 8132 are respectively arranged on two sides of the transverse beam 811. The second swinging plate 8131 and the second connecting flange 8132 are connected by a pin shaft.

Multiple second swinging plates 8131 are connected with the second drive plate 8121, such that the movement of the second drive plate 8121 drives the multiple second swinging plates 8131 to deflect.

Thus, second detection rods 8133 connected with second connecting flanges 8132 swing simultaneously to contact longitudinal steel bars at the detection points of the steel bars 1916. Since the structure of the longitudinal contact devices 833 and the transverse contact devices 813 are the same, only the longitudinal contact devices 833 are described as an example.

The first swinging plate 8331 is connected with the first connecting flange 8332 through the square rod.

When the first drive member 8322 pushes the first drive plate 8321 to move along the length direction of the longitudinal beam 831, an upper end of the first swinging plate 8331 follows the first drive plate 8321 to move along the length direction.

Thus, the first swinging plate 8331 swings to drive the first connecting flange 8332 connected with the other end of the

-28- square rod to swing, and then the first detection rod 8333 swings.

In this embodiment, in an initial state, a bottom side of the first connecting square hole is in a horizontal state, and the first detection rod 8333 is in a vertical state.

The first connecting square hole of the first swinging plate 8331 is convenient for observing whether the first detection rod 8333 returns to the vertical state after detection is completed, so as to ensure the verticality of the first detection rod 8333. in order to adapt to the arrangement of detection points on the track slabs of different specifications, the first detection rod 8333 can swing to the left or right, such that the first swinging plate 8331 is provided in a forward direction or in a reverse direction.

The direction shown in FIG.14 is the forward direction.

Referring to FIG. 13, a first limiting hole 83211 is further provided in the first drive plate 8321. The first limiting hole 83211 has an elongated structure.

A limiting rod is provided on the longitudinal beam 831. Two ends of the limiting rod extend out of the first limiting hole 83211 to limit the moving range of the first drive plate 8321, thereby limiting the swing amplitude of the first swinging plate, and then controlling the swing angle of the first detection rod 8333. The longitudinal lifting mechanisms 84 are provided at two ends of the longitudinal beam 831, respectively.

The longitudinal lifting mechanisms 84 each include a first guide rail 841, a first slider 842 and a first driving motor 843. The first slider 842 is slidably connected with the first guide rail 841. The first slider 842 is connected with one end of the longitudinal beam 831 through a first mounting base 844. The first driving motor 843 drives the first slider 842 to move linearly along the first guide rail 841. The transverse lifting mechanisms 82 are respectively provided at two ends of the transverse beam 811. The transverse lifting mechanisms 82 each include a second guide rail 821, a second slider 822 and a second driving motor 823. The second slider 822 is slidably connected with the second guide rail 821. The second slider 822 is connected with one end of the transverse beam 811 through a second mounting base 824. The second driving motor 823 drives the second slider 822 to move linearly along the second guide rail 821. In practical applications, in order to facilitate a rail cart 1912 to enter the position, a transverse support base assembly 85 and two longitudinal support base assemblies 86 are further provided at a bottom end of the entire device.

The longitudinal support base assemblies 86 each include a support beam 861 and a first support base 862 connected with two ends of the support beam 861. The first guide rail 841 is connected with the support beam 861 through a first connecting base 863. The transverse support base assembly 85 includes two opposite

-29- second support bases 851. The second support bases 851 are used to connect second guide rails 821. In this embodiment, three longitudinal detection mechanisms 83 are provided.

The three longitudinal detection mechanisms 83 are arranged in parallel, and the two ends of each of the three longitudinal detection mechanisms 83 are respectively connected with support beams 861 through the first connecting bases 863. The three longitudinal detection mechanisms 83 are capable of detecting steel bars 1916 of different specifications.

Further, this embodiment further provides a steel bar insulation performance detection method, using the steel bar insulation performance detection device in Embodiment 1. In practical applications, the steel bar 1916 insulation performance detection device further includes a control device and an insulation detection cabinet.

The longitudinal contact devices 833 and the transverse contact devices 813 are electrically connected with the insulation detection cabinet, The control device is electrically connected with the longitudinal swinging drive device 832, the longitudinal contact devices 833, the longitudinal lifting mechanisms 84, the transverse swinging drive device 812, the transverse contact devices 813, the transverse lifting mechanisms 82 and the insulation detection cabinet.

As shown in FIGS. 15 and 16, this step is in an initial state of the steel bar 1916 detection device. lt should be noted here that the meshes of type IH steel bars are commonly braided in three specifications.

For each specification, the transverse width of the fabric sheet is the same, but the fabric sheets on the upper and lower layers are staggered, and the spacing of the fabric sheets on the longitudinal length is different. $82.

Station 9: Track slab pouring station The track slab pouring station 9 includes a pouring mechanism, a support member, a jacking mechanism and a vibrating mechanism.

A sidewall of the pouring mechanism is provided with a pouring port. The pouring port is aimed at the track slab mold 1915 at the track slab pouring station 9 to pour concrete into the cavity of the track slab mold 1915.

A bottom of the pouring mechanism is provided obliquely to facilitate the concrete to slide down from the pouring port due to its own weight.

The support member is an integral plate. The jacking mechanism and the vibrating mechanism are located below the support member. The track slab mold 1915 at the track slab pouring station 9 is supported on the support member.

-31- The jacking mechanism drives the track slab mold 1915 to move up and down through the support member.

When the track slab assembly moves upward, it leaves a moving track on the ground.

The vibrating mechanism drives the track slab mold 1915 to vibrate through the support member, such that the concrete is evenly distributed in the cavity of the track slab mold 1915, An existing support member is a box formed by welding multiple plates.

When the vibrating mechanism drives the track slab mold 1915 to vibrate through the support member, the existing support member is under high-frequency vibration, and the welded joint is easily damaged and cracked.

The support member with an integral plate structure has no welded joints, which greatly improves the reliability of the support member and prolongs the service life of the support member.

Station 10: Steam curing station (FIGS. 21 to 34) Refer to FIG. 21 for the "up" and "down" directions of this station.

The directions of a swing arm 10122 are defined as “front” and "rear" directions.

The direction of a main beam platform 10111 close to a steam curing zone103 is defined as a "left" direction, and the direction of the main beam platform 10111 away from the steam curing zone 103 is defined as a “right” direction.

The steam curing station 10 includes the steam curing zone 103 and a hoist.

The hoist is used to lift the track slab assembly 191 to a position corresponding to any layer and any column of three-dimensional steam curing channels 1031. The steam curing zone 103 is used to accelerate the solidification rate of concrete in the track slab and keep the track slab at a certain humidity, so as to improve the quality of the track slab 1914. The multi-layer and multi-column three-dimensional steam curing channels 1031 reduce the area of the steam curing zone 103 and solve the problems existing in the prior art.

The existing steam curing zone occupies a large area, which results in a large area for arranging tubes and workshops, thereby increasing the cost of construction.

In addition, the subsequent equipment is hard to reuse, and the land is not easy to re-cultivate, causing great waste.

In the production workshop of the track slab 1914, when a casted track slab 1914 is transported to the steam curing station, a pallet 1911, a rail cart 1912, the molded track slab 1913 are sequentially arranged from bottom to top.

The pallet 1911, the rail cart 1912, the molded track slab 1913 define a track slab assembly 2. The molded track slab 1913 includes a track slab mold 1915 and a track slab 1914. The track slab 1914 is accommodated in the track slab mold 1915. A top of the pallet 1911 is provided with pallet rails 19111 and connecting pieces.

The pallet rails 19111 are used for the rail cart 1912 to be slidably provided on the

-32- pallet 21. The top of the pallet 1911 protrudes upward to form pallet push plates 19112. The pallet push plates 19112 are provided with pallet push plate through holes 19113, and the pallet push plate through holes 19113 extend horizontally in the front and rear directions. The hoist includes a main beam platform assembly and a lifting frame assembly. The main beam platform assembly is used to move the track slab assembly 191 horizontally to correspond to any column of the three-dimensional steam curing channels 1031 in the steam curing zone 103. The lifting frame assembly is used to lift the track slab assembly 191 to correspond to any layer of the three-dimensional steam curing channels 1031 in the steam curing zone 3.

The main beam platform assembly includes the main beam platform 10111. The main beam platform 10111 corresponds to a top of the steam curing zone 3. The main beam platform 10111 is able to move horizontally to correspond to any column of the three-dimensional steam curing channels 1031. The lifting frame assembly is provided below the main beam platform 10111. The lifting frame assembly is able to move up and down relative to the main beam platform 10111 to correspond to any layer of the three-dimensional steam curing channels 1031. The lifting frame assembly includes a lifting frame 10121, the swing arm 10122 and a track slab pushing assembly. The swing arm 10122 includes a first swingarm and a second swing arm which are arranged oppositely on front and rear sides of the lifting frame

10121. The first swing arm and the second swing arm each have an upper ends rotatably connected with the lifting frame 10121 and rotate synchronously relative to the lifting frame 10121 to clamp the track slab assembly 191. The track slab pushing assembly is located at a lower part of the swing arm 10122 and is used to drive the track slab assembly 191 to move in the left and right directions.

The working principle of the steam curing system of the track slab 1914 is as follows: The main beam platform 10111 moves horizontally to correspond to a column of the three- dimensional steam curing channels 1031. The first swing arm and the second swing arm clamp the track slab assembly 191. When the lifting frame assembly moves up or down to a position corresponding to a layer of the three-dimensional steam curing channels 1031, the pallet rails 19111 on the top of the pallet 1911 are flush with tops of the inlet rails of the three- dimensional steam curing channels 1031. The track slab pushing assembly drives the track slab assembly 191 to move left until the pallet rails 19111 are connected with the inlet rails. Traction members provided at an inlet of the three-dimensional steam curing channels 1031 are fixed to the rail cart 1912, and pull the rail cart 1912 and the molded track slab 1913 to synchronously move left to enter the three-dimensional steam curing channel 1031 for steam

-33- curing. The track slab pushing assembly drives the pallet 1911 to move right to leave the inlet rails. When the steam curing is completed, the traction members pull the rail cart 1912 and the molded track slab 1913 to synchronously move right, so as to send the rail cart 1912 and the molded track slab 1913 out of the three-dimensional steam curing channel 1031 and return to the top of the pallet 1911. Then the track slab pushing assembly pushes the track slab assembly 191 to move right to leave the inlet rails. In summary, based on the structure and working principle of the steam curing system of the track slab 1914, in the present disclosure, the track slab assembly 191 is clamped by a translation cart on the ground and lifted to correspond to any layer and any column of the three-dimensional steam curing channels 1031. The rail cart 1912 and the molded track slab 1913 are synchronously sent into the three-dimensional steam curing channel 1031 for steam curing. After the steam curing is completed, the rail cart 1912 and the molded track slab 1913 are simultaneously moved out of the three-dimensional steam curing channel 1031. Then, the track slab assembly 191 is returned to the translation cart on the ground to complete the entire steam curing process. The hoist in the present disclosure is suitable for the steam curing zone 103 provided with multi-layer and multi-column three-dimensional steam curing channels 1031. It can lift and send the track slab 1914 into any one of the three-dimensional steam curing channels 1031 for steam curing, and moves the track slab 1914 out of the three-dimensional steam curing channel 1031 at the end of the steam curing. Further, the first swing arm and the second swing arm are able to rotate synchronously to a first position and a second position relative to the lifting frame 10121. When the first swing arm and the second swing arm rotate to the first position, the first swing arm and the second swing arm can clamp the track slab assembly 191.

When the first swing arm and the second swing arm rotate to the second position, a distance between a lower end of the first swing arm and a lower end of the second swing arm is greater than a width of the track slab assembly 191. Preferably, two first swing arms and two second swing arms are spaced apart. The first swing arms include two spaced-apart first support arms. The second swing arms include two spaced- apart second support arms. The two first support arms are connected by a connecting piece, and the two second support arms are connected by a connecting piece to improve the stability of the first swing arm and the second swing arm clamped on the track slab assembly 191. Further, a swing arm drive assembly is provided between the first swing arm and the second swing arm. The swing arm drive assembly is used to drive the first swing arm and the second

-34- swing arm to rotate synchronously relative to the lifting frame 10121 to the first position and the second position. The swing arm drive assembly includes a push arm drive mechanism 101241, a push arm 101242, a torsion arm 101243, a first push rod 101244 and a second push rod 101245.

The push arm drive mechanism 101241 is fixed on the lifting frame 10121. One end of the push arm 101242 is rotatably connected with a push end of the push arm drive mechanism

101241. The push arm drive mechanism 101241 drives an end of the push arm 101242 connected with the push arm drive mechanism 101241 to move horizontally in the front and rear directions. The other end of the push arm 101242 is fixed to the torsion arm 101243 and is located at a middle length position of the torsion arm 101243. One end of the torsion arm 101243 is rotatably connected with the first push rod 101244, and the other end thereof is rotatably connected with the second push rod 101245. An end of the first push rod 101244 away from the torsion arm 101243 is fixed to an upper end of the first swing arm, and an end of the second push rod 101245 away from the torsion arm 101243 is fixed to an upper end of the second swing arm.

Preferably, the push arm drive mechanism 101241 is a hydraulic cylinder.

As an example, the first swing arm is located on the front side of the lifting frame 10121, and the second swing arm is located on the rear side of the lifting frame 10121. A driving end of the push arm drive mechanism 101241 is close to the first swing arm. In the initial position, the first swing arm and the second swing arm are in the first position. The swing arm drive assembly drives the first swing arm and the second swing arm to rotate to the second position synchronously relative to the lifting frame 10121 as follows: The driving end of the push arm drive mechanism 101241 extends to drive the end of the push arm 101242 connected with the push arm drive mechanism 101241 to move forward. The other end of the push arm 101242 rotates clockwise, and drives the end of the torsion arm 101243 close to the first push rod 101244 and the end close to the second push rod 101245 to synchronously rotate clockwise. A distance between the end of the first push rod 101244 away from the torsion arm 101243 and the end of the second push rod 101245 away from the torsion arm 101243 is reduced. Thus, the distance between the lower end of the first swing arm and the lower end of the second swing arm is increased to be greater than the width of the track slab assembly 191.

When it is necessary to change the first swing arm and the second swing arm from the second position to the first position, the specific operation is as follows:

-35- The driving end of the push arm drive mechanism 101241 is shortened to drive the end of the push arm 101242 connected with the push arm drive mechanism 101241 to move backward. The other end of the push arm 101242 rotates counterclockwise, and drives the end of the torsion arm 101243 close to the first push rod 101244 and the end close to the second push rod 101245 to synchronously rotate counterclockwise. The distance between the end of the first push rod 101244 away from the torsion arm 101243 and the end of the second push rod 101245 away from the torsion arm 101243 is increased. Thus, the distance between the lower end of the first swing arm and the lower end of the second swing arm is reduced, such that the first swing arm and the second swing arm are clamp the track slab assembly 191.

Specifically, rollers 101221 are provided below the first swing arm and the second swing arm. The roller 101221 below the first swing arm and the roller 101221 below the second swing arm are arranged opposite to each other. The pallet 1911 of the track slab assembly 191 is slidably provided on the rollers 101221, such that the track slab pushing assembly drives the track slab assembly 191 to move horizontally in the left and right directions.

Further, the track slab pushing assembly includes a push rod driving mechanism 101231 and a pallet push rod 101232. The push rod driving mechanism 101231 is fixed to the lower part of the swing arm 10122. The push rod driving mechanism 101231 is used to drive the pallet push rod 101232 to move in the left and right directions. The pallet push rod 101232 is horizontally provided in the front and rear directions, and is matched with the pallet push rod through hole ofthe pallet 1911.

The track slab pushing assembly drives the track slab assembly 191 to move horizontally in the left and right directions as follows: When the first swing arm and the second swing arm rotate to the first position and are clamp the track slab assembly 191, the pallet push rod 101232 is inserted into the pallet push rod through hole. The push rod driving mechanism 101231 drives the pallet push rod 101232 to move left to drive the track slab assembly 191 to move left until the pallet rails 19111 are connected with the inlet rails, or to drive the track slab assembly 191 to move right to leave the inlet rails.

Preferably, the track slab pushing assembly further includes a pushing slide rail 101233 and a pushing slider 101234. The pushing slide rail 101233 is provided on the swing arm 10122, and the pushing slide rail 101233 extends horizontally in the left and right directions. The pushing slider 1234 is slidably provided on the pushing slide rail 101233 and fixed to the driving end of the push rod driving mechanism 101231. The pushing slider 101234 is fixedly connected with the pallet push rod 101232. The push rod driving mechanism 101231 drives the pushing slider

-36- 101234 to move in the left and right directions along the pushing slide rail 101233 so as to drive the pallet push rod 101232 to move in the left and right directions. More preferably, there are two track slab pushing assemblies, which are symmetrically arranged on the first swing arms and the second swing arms, and are respectively located between the two first swing arms and between the two second swing arms. The track slab pushing assembly further includes a push rod displacement sensor 101235. The push rod driving mechanism 101231 located on the first swing arm and the push rod driving mechanism 101231 located on the second swing arm can synchronously drive the pushing slider 101234 to move in the left and right directions along the pushing slide rail 101233. In this way, the track slab pushing assembly on the first swing arm and the track slab pushing assembly on the second swing arm can synchronously drive the track slab assembly 191 to move in the left and right directions.

Specifically, the push rod driving mechanism 101231 is preferably a hydraulic cylinder. Further, guiding members are respectively provided on the front and rear sides of the lifting frame 10121. The guiding members each include spaced-apart lifting frame guide wheels 101211 and spaced-apart lifting frame guide plates 101212.

Pressing member drive mechanisms 101213 are fixedly provided on the lifting frame 10121. Drive ends of the pressing member drive mechanisms 101213 are fixedly connected with pressing members 101214. The pressing member drive mechanisms 101213 are used to drive the pressing members 101214 to move horizontally in the front and rear directions. The pressing members 101214 are used to fix the lifting frame assembly at a position corresponding to any layer of the three-dimensional steam curing channels 1031.

The pressing member drive mechanisms 101213 are preferably air pumps. The pressing members 101214 are preferably positioning pins.

The left and right sides of the lifting frame 10121 are symmetrically provided with first movable pulleys 101215 and second movable pulleys 101216. The first movable pulleys 101215 and the second movable pulleys 101216 are located on the top of the lifting frame

10121. The first movable pulleys 101215 and the second movable pulleys 101216 are used to drive the lifting frame 10121 to move up and down.

The main beam platform 10111 is further provided with a lifting drive mechanism. The lifting drive mechanism is used to drive the wire rope drums 101113 to rotate so as to drive the lifting frame assembly to move up and down.

One wire rope 1013 is wound around the first fixed pulleys 101112, the first movable pulleys 101215, the balance pulleys 101111 and the wire rope drums 101113 in sequence, and the other wire rope 1013 is wound around the second fixed pulleys 101114, the second movable pulleys 101216, the wire rope fixing frames 101115 and the wire rope drums 101113 in sequence. The lifting driving mechanism drives the wire rope drum 101113 to rotate so as to drive the first movable pulleys 101215 and the second movable pulleys 101216 to move up or down synchronously, thereby driving the lifting frame assembly to move up or down synchronously.

The lifting driving mechanism is preferably a motor brake 1011161 and a reducer 1011162, and the motor brake 1011161 drives the wire rope drums 101113 to rotate through the reducer

1011162. Further, the bottom of the main beam platform 10111 is provided with driving wheels

1011171. There are an even number of driving wheels 1011171, two or more, which are symmetrically arranged on the front and rear sides of the main beam platform 10111. The driving wheels 1011171 are slidably arranged on a guide rail of a beam to drive the main beam platform 10111 to move horizontally. The beam is used to support the hoist to move in the air. Preferably, each of the four end points of the main beam platform 10111 is provided with one driving wheel 1011171 to improve the stability of the main beam platform 10111 moving horizontally.

Specifically, in order to drive the driving wheels 1011171 to slide along the guide rails of the beam, driving wheel driving mechanisms 1011172 are further provided on the main beam platform 10111. The driving wheel drive mechanisms 1011172 are preferably gear motors.

-38- Specifically, the driving wheels 1011171 are arranged on the main beam platform 10111 through a driving wheel frame 1011173. The driving wheel frame 1011173 is located at the bottom of the main beam platform 10111. Further, a hoist positioning assembly is provided on a left side of the main beam platform 10111 for precise positioning of any column of three-dimensional steam curing channels 1031.

The hoist positioning assembly includes a hoist positioning member 1011181 and a positioning member driving mechanism 1011182, The hoist positioning member 1011181 is vertically provided, and the positioning member driving mechanism 1011182 is used to drive the hoist positioning member 1011181 to move up and down. The top of the steam curing zone 3 is provided with steam curing zone positioning holes 1032 corresponding to each column of the three-dimensional steam curing channels 1031. The steam curing zone positioning holes 1032 are matched with the hoist positioning member 1011181. When the main beam platform 10111 moves horizontally to correspond to any column of the three-dimensional steam curing channels 1031, the positioning member driving mechanism 1011182 drives the hoist positioning member 1011181 to move downward to be inserted into a corresponding positioning hole 1032. Thus, the main beam platform 10111 is precisely located at any column of the three-dimensional steam curing channels 1031 to improve the position accuracy of the hoist and avoid the hoist from derailing. Further, the main beam platform assembly further includes a guide rail frame 10112 located below the main beam platform 10111. The guide rail frame 10112 is vertically provided. The guide rail frame 10112 includes a first guide rail frame and a second guide rail frame.

-39- directions to press against the top of a corresponding lifting frame positioning member 10114. In this way, the lifting frame assembly is accurately fixed to correspond to any layer of the three-dimensional steam curing channels 1031. The lifting frame positioning members 10114 are preferably screws.

Preferably, when the lifting frame guide wheel 101211 is damaged, the lifting frame guide plate 101212 can be fixed on the lifting frame guide rail 10113 to fix the lifting frame 10121 so as to prevent the lifting frame assembly from falling out of control, thereby improving the safety of use.

More preferably, there are two spaced-apart first guide rail frames and two spaced-apart second guide rail frames. The two first guide rail frames and the two second guide rail frames are respectively connected by support frames 10115. This improves the stability of the lifting frame 10121 sliding up and down along the first guide rail frames and the second guide rail frames, and improves the use strength of the first guide rail frames and the second guide rail frames. In order to reduce the weight of the support frames 10115, the support frames 10115 have a hollow structure. Due to the support frames 10115, when the lifting frame assembly moves up and down, the first swing arms and the second swing arms of the lifting frame assembly can be controlled to rotate to the second position after the lifting frame assembly moves down to below the support frames 10115. In this way, the interference between the first swing arms and the second swing arms and the support frames 10115 is avoided. it should be noted that, in order to be suitable for the lifting operation of the track slab assembly 191, the load-bearing capacity of the following components used is adapted to the weight of the track slab assembly 191: the balance pulleys 101111, the first fixed pulleys 101112, the first movable pulleys 101215, the wire rope drums 101113, the second fixed pulleys 101114, the second movable pulleys10 1216, the wire rope fixing frames 101115, the wire ropes 10113, the main beam platform 10111, the guide rail frame 10112, the lifting frame 10121, the swing arm 10122 and the rollers 101221.

A lower limit mechanism is used to limit a downward movement position of the track slab. The internal door-shaped bar grabbing mechanism is used to grab door-shaped bars on the track slab to lift

-42- the track slab out of the track slab mold 1915. The demolding sensor acquires corresponding data, and a control system controls key mechanisms to act in sequence to achieve the overall synchronous lifting for demolding. The working principle of this station is as follows: After the track slab assembly 191 is transferred to the track slab demolding station 12, the limit mechanism fixes the track slab mold. The door-shaped bar grabbing mechanism automatically descends to grab the door-shaped bars on the track slab. The molded track slab is fixed by limit posts, and multiple door-shaped bars on the track slab 1914 are lifted synchronously. In this way, the track slab 1914 is synchronously lifted at a uniform speed, such that the track slab 1914 is separated from the track slab mold 1915 to complete demolding. When the track slab 1914 is lifted to a certain height, a pouring hole forming device removing system automatically starts, and track slab pouring holes are removed. The removed pouring holes remain on the mold without manual handling. After the pouring holes are removed, the integral running mechanism carries the track slab 1914 to an electric powered cart. Then the track slab 1914 is transported to the track slab turning station 13 by the electric powered cart. An automatic hoisting system of the track slab adopts fully automatic control. The whole process relies on the data of various sensors to manipulate a hydraulic pump station to control the precise action of a jack 7334. The track slab 1914 receives uniform force.

The vision system is used to take pictures of the track slab 1914 to obtain a position deviation of the track slab 1914 and send the position deviation to the robot via a main console. The robot automatically corrects the deviation of

-43- the track slab 1914, and then seals anchor holes of the track slab 1914. The robot is provided with an anchor sealing assembly, which carries out spraying, grouting and automatic smoothing operations on the anchor holes in sequence during anchor sealing. Station 15: Track slab detection station The track slab detection station 15 realizes the rapid modeling of the three-dimensional size of the track slab 1914 and the automatic detection and evaluation of key geometric dimensions through laser image detection technology. It can greatly improve the detection efficiency and ensure the construction quality of the track slab 1914. Station 16: Track slab water-curing station 16 The track slab water-curing station 16 has the following requirements: (1) Water curing is carried out in 2 h after the track slab is sealed and in 8 h after the track slab is demolded, where the track slab keeps moist during the period from demolding to water curing.

{2) The track slab is water-cured for no less than 3 d, and is kept warm and moist for totally no less than 10d.

{3) Before the track slab is soaked in water, the embedded casing and the ground terminal on the track slab are sealed with a plastic cover to prevent debris from entering.

{4) Before the track slab is soaked in water, the anchor sealing mortar must have certain strength, and it may not peel off or drop slag when the track slab is water-cured.

(5) The minimum water temperature in a curing pool is not less than 10°C, and the difference between the surface temperature of the track slab and the water temperature is not more than 10°C.

(6) After the water curing is completed, the track slab is stored outdoors when the difference between the surface temperature of the track slab and the outdoor environment temperature is not more than 15°C. When the track slab is stored outdoors, the track slab is covered with geotextile for 28 d and moisturized for 7 d. During construction in winter, the track slab is stored outdoors after its surface is dry. When the track slab is stored outdoors, the surface of the track slab is coated with a curing fluid or is subjected to automatic curing.
