Exemplary embodiments that embody features and advantages of the present invention are described in detail in the following description. It will be understood that the invention is capable of various modifications in various embodiments, all without departing from the scope of the invention, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the invention.

As shown in FIG. 1, the underground curing system for the prefabricated parts comprises a die table 1, an overground production line, an underground curing entering station, a stacker crane 5, a curing warehouse and a control center. The ground production line comprises a cleaning station, a template loading station, a steel bar binding station, a buried part loading station, a quality inspection station, a material distribution and vibrating station, a ferrying station, a buffering station and a napping station. The production process of one prefabricated part comprises the following steps: selecting an idle mould table 1 to be placed on the ground production line, entering a cleaning station to clean scraps on the mould table 1, entering a template loading station, installing a corresponding template on the mould table 1 according to the specification and size required by the prefabricated part, after fixing the template, entering a reinforcing steel bar binding station to bind reinforcing steel bar meshes in the internal space enclosed by the template, entering a buried part loading station, installing corresponding buried parts such as bolts, lifting hooks and reinforcing steel bars at corresponding positions according to requirements, entering a quality inspection station, detecting the templates, reinforcing steel bars, buried parts and the like installed in the previous working procedure, if the installation and quality are over-closed, entering the next working procedure, otherwise, taking out and reinstalling until the template is qualified, and entering the next working procedure together; the next working procedure is distributing and vibrating, wherein a distributing machine and vibrating equipment are arranged on the working position, when the distributing machine receives a discharging command, concrete components such as cement, sand, stones, water and the like are mixed and stirred according to a certain proportion, then poured into an internal space surrounded by the templates, then started to vibrate, the internal space surrounded by the templates is filled up, and then plastering treatment is carried out; and then transferring to a production line in the other direction through a ferrying station, entering a buffering station, waiting to enter a roughening station at the buffering station, roughening at the roughening station to enable the surface to be smooth and tidy, basically completing the production and manufacture of the prefabricated part, generating a two-dimensional code by related software to cover the personalized information of the prefabricated part such as size specification, components, arrangement number, molding time, expected entering curing bin time, leaving curing bin time and the like before entering an underground curing station, and pasting the two-dimensional code on the die table 1 carrying the prefabricated part. A plurality of prefabricated parts can be manufactured on one die table 1, preferably, one die table 1 carries three prefabricated parts, and the two-dimensional code on the die table 1 simultaneously comprises information of the three prefabricated parts.
The two-dimensional code scanner is arranged on the underground maintenance entering station and is fixed on the underground maintenance entering station through a bracket, and a probe of the two-dimensional code scanner is right opposite to the lower side. When the die table 1 enters the underground maintenance entering station, the two-dimensional code can just pass through the position right below the two-dimensional code scanner. When the two-dimensional code completely enters the scanning range of the two-dimensional code scanner, the two-dimensional code scanner can scan the code and acquire the information carried by the two-dimensional code, then the two-dimensional code information is transmitted to the control center, and the control center stores and records the related two-dimensional code information.
The maintenance bin changes the traditional setting mode and is arranged underground, which is equivalent to carrying the traditional overground maintenance bin part to the underground, thus greatly saving the land space and expanding the bin space of the maintenance bin. The maintenance bin is a closed accommodating cavity underground and is communicated with the outside only by virtue of an inlet gate and an outlet gate. The stacker crane 5 is placed between the inlet and outlet positions of the curing bin, the base of the stacker crane 5 is flush with the bottommost surface of the curing bin, and the stacker crane is highly communicated with the ground and the ground, so that the die table 1 can be transported from the ground to the ground. The maintenance bin can be provided with multiple layers, preferably two layers, which are mutually independent and not affected. The arrangement of each layer is concave under the overlook angle, the concave position is the activity area of hacking machine 5, the hacking machine 5 both sides are many business turn over, the exit channel of curing storehouse, each passageway is independent and parallel each other. Preferably, three inlet and outlet channels are provided. The die table 1 can select different inlet channels for feeding and different outlet channels for discharging. The inlet channel and the outlet channel are communicated with each other through a ferry station and a common channel. The ferry station has the functions that: the die table is allowed to change advancing path and change direction by 180 °. The common channel is a linear coherent channel which is parallel to the stacker crane 5 and is connected with the inlet and outlet channels. The common channels may be arranged in a number of mutually parallel, preferably one. Because the length of the common channel is longer, and is the sum of the lengths of the inlet channel, the outlet channel and the movable area of the stacker crane 5, the number of the die tables 1 can be increased, and almost all the die tables 1 under the peak period of the inlet channel can be accommodated. If the shared channel is added, the land area is increased, which is unfavorable for resource optimization. In addition, the common channel is connected with the inlet channel and the outlet channel through the ferry stations, namely, the common channel and the outlet channel are sequentially connected in the following order: the inlet channel, the ferrying station, the common channel, the ferrying station on the other side and the outlet channel. The five modules are sequentially connected to form an automatic assembly line of the maintenance bin. The two ferrying stations are arranged at two ends of the curing bin and are perpendicular to the shared channel, the inlet channel and the outlet channel. The die table 1 sequentially passes through the curing bins in and out: the palletizer 5, the inlet channel, the ferrying station, the common channel, the ferrying station on the other side and the outlet channel are returned to the palletizer 5 again, namely, the palletizer 5 is conveyed into the inlet channel, continuously moves forwards on the inlet channel until entering the ferrying station, transversely moves to the common channel on the ferrying station, then continuously moves forward on the common channel in the direction 180 DEG opposite to the moving direction of the inlet channel, and then transversely moves to the outlet channel along with the advancing movement, continuously moves in the same direction as the moving direction of the inlet channel on the outlet channel until reaching the outlet of the curing bin, and finally returns to the palletizer 5 again. The curing of the prefabricated component is completed, the moving process of the die table 1 in the curing bin is the curing process, and the time from entering the bin to exiting the bin is the curing time. And then the stacker crane 5 lifts and conveys the die table 1 back to the ground, enters an underground curing kiln-discharging station, queues up to enter a die-removing station, and removes edges of the prefabricated components on the die table 1 in the die-removing station, so that after die removal is completed, the production and manufacturing processes of one prefabricated component are all completed, and the prefabricated components can be conveyed to leave a factory.
The maintenance bin consists of a plurality of automatic assembly lines, and each automatic assembly line is independent and does not affect each other. The automatic assembly line is provided with a driving wheel 3 and a travelling wheel 4; when the mould table 1 carries prefabricated parts to walk on the driving wheel 3 and the travelling wheel 4, the prefabricated parts are pushed by the driving wheel 3. The driving wheel 3 is driven by a motor positioned close to the driving wheel, a first control unit, a manual starting switch and an automatic control starting switch are arranged on the motor, and a signal receiving module is arranged in the first control unit. The manual starting switch and the automatic control switch are used for starting or stopping the motor, so that the rotation of the driving wheel 3 is driven or stopped, and the purpose of moving or stopping the die table 1 on the driving wheel 3 is achieved. The manual starting switch can directly start the motor to drive the driving wheel 3 to work in order to facilitate people to start the motor on site. The automatic control switch is electrically connected to the first control unit, the first control unit is connected to the control center in a communication way, and the first control unit can send out an instruction to act on the automatic control switch to enable the automatic control switch to be started or closed; the control center arranged in the control room can send out an instruction to the control unit, and then the control unit directly controls the automatic control switch to realize remote control of starting or closing of the automatic control switch. When the motor works and drives the driving wheel 3 to rotate, the die table 1 on the motor moves forwards under the action of thrust, and the travelling wheel under the motor drives the die table 1 to roll due to friction force to play a role of driven, so that the die table 1 moves more smoothly. Moreover, the travelling wheels 4 can also play a role in supporting the die table 1, so that the die table 1 is stressed uniformly, and the abrasion of the die table 1 to the driving wheel 3 is reduced. The control unit can receive the obstacle signal emitted by the sensor 2 within a certain range, and accordingly control the automatic control switch.
Each automatic line channel consists of two symmetrical tracks, the driving wheels 3 are arranged on the two tracks in an asymmetric staggered interval arrangement, each track consists of a plurality of driving wheels 3 and a plurality of travelling wheels 4 in an alternating manner, and a plurality of travelling wheels 4 are arranged between every two adjacent driving wheels 3. Preferably, one travelling wheel 4 is arranged between two adjacent driving wheels 3, that is, the driving wheels 3 and the travelling wheels 4 extend continuously and alternately, so that the thrust exerted by the die table 1 can be uniformly distributed, and the condition that the driving wheels work continuously, but the die table 1 stops or even deviates can not occur. The channel of the automatic assembly line is divided into a plurality of units along the moving direction of the die table, each unit comprises a plurality of driving wheels and a plurality of travelling wheels, and the driving switches of the driving wheels under each unit are interlocked, namely, the driving switch of any driving wheel in one unit is started and stopped, and the driving switch of all driving wheels in the unit is driven to be started and stopped simultaneously. The driving switch comprises a manual starting switch and an automatic control starting switch. Typically, one of the die stations 1 is sized to cover exactly one cell's channel. Preferably, each unit comprises 3 said drive wheels.
The die table 1 is provided with inductors 2 at the front and rear ends in the moving direction, and the inductors are connected to a first control unit on the motor of the driving wheel 3 in a communication manner. The sensor 2 is a radar or laser emitting and receiving device. The sensor 2 can continuously send out a detection signal, receive and process information when the detection signal bounces back when encountering an obstacle, and make judgment and send out instructions. When the distance between the obstacle and the obstacle is far and is not in the radiation range of the inductor 2, the inductor 2 cannot receive the rebound signal, and the normal condition is judged; when the distance between the obstacle and the obstacle is short, and the radiation range of the sensor 2 is within, the sensor 2 receives the rebound signal, judges that the obstacle is abnormal, sends out an obstacle signal, radiates to the periphery, transmits the obstacle signal to the peripheral control unit I, informs the obstacle, so that the control unit sends out an instruction to turn on the automatic control switch, simultaneously stops all driving wheels of the unit, and the die table 1 stops moving. I.e. the sensor 2 is able to sense obstacles in a certain range and to radiate to the control unit one in a certain range. Since the movement of the mold table 1 is driven by the driving wheels of the adjacent two unit passages, and the radiation range of the sensor 2 is larger than the distance between the two unit passages, when an obstacle is encountered, such as a person standing by mistake in the advancing direction of the mold table 1 and being close to the distance, the mold table 1 is prevented from colliding with the person, and when the mold table 1 needs to be suspended, the driving wheel 3 of the current unit passage of the mold table 1 and part or all of the control units of the driving wheel 3 of the previous unit passage receive fault signals, and all of the driving wheels of the two units are controlled to stop driving, so that the mold table 1 can be stopped in place in time. When the person leaves the forward passage of the die table 1 or the die table 1 positioned in front has continued to advance, the die table 1 stopped in place needs to be moved again, the manual switch can be started manually on site or can be started through remote control of the control center.
The position of the inlet and the outlet of the maintenance bin is respectively provided with a signal receiver 6, and the signal receivers are correspondingly connected to a second control unit of the inlet and the outlet. The second control unit is also connected to a gate switch of the inlet and the outlet. The number of the inlet and outlet positions corresponds to the number of the inlet and outlet channels respectively, each inlet and outlet position is provided with one signal receiver 6, and each inlet and outlet is provided with a second control unit. When one of the signal receivers 6 of the maintenance bin receives the detection signal sent by the sensor 2 on the die table 1, the detection signal is transmitted to the corresponding control unit II, the control unit II sends out an instruction to act on the corresponding gate switch, and one inlet of the corresponding signal receiver 6 is opened. Meanwhile, since the detection signal of the sensor 2 is received by the signal receiver and is not reflected back, the sensor can also treat the situation as normal, and the action of sending out the signal is kept, so that no obstacle signal is sent out.
The control center is communicatively connected to the palletizer 5, the underground curing station and the curing barn, respectively. In addition, the control center is specifically in communication connection with the two-dimensional code scanner, the first control unit and the second control unit. The control center can send out instructions according to production requirements to drive the stacker crane 5 to work, enable the stacker crane 5 to transfer the die table 1 to a position and a height, control rotation of the driving wheel 3 of a unit and control opening and closing of gates of an inlet and an outlet. Preferably, when the sensor 2 senses an obstacle, the corresponding control unit will feedback a stop signal to the control center when stopping the driving wheel 3, so that the operator knows which unit the driving wheel is stopped. The stacker crane 5 is a suspension type crane, the conveying speed is high, the lifting height can be adjusted at will, and the rapid in-out of the components can be realized.
In another embodiment, a method for using the underground maintenance system for prefabricated components is provided, which comprises the following steps:
the prefabricated part is produced and manufactured on the ground production line through the working procedures of cleaning, template loading, embedded part loading, quality inspection, cloth, vibrating, napping and the like, and then a two-dimensional code is stuck on the die table 1 for carrying the prefabricated part. The two-dimensional code can cover the individual information of the prefabricated component, such as size specification, components, row number, molding time, expected entering maintenance bin time, exiting maintenance bin time and the like. The two-dimensional code scanner is arranged on the underground maintenance entering station and is fixed on the underground maintenance entering station through a bracket, and a probe of the two-dimensional code scanner is right opposite to the lower side. When the die table 1 enters the underground maintenance entering station, the two-dimensional code can just pass through the position right below the two-dimensional code scanner. When the two-dimensional code completely enters the scanning range of the two-dimensional code scanner, the two-dimensional code scanner can scan the code and acquire the information carried by the two-dimensional code, then the two-dimensional code information is transmitted to the control center, and the control center stores and records the related two-dimensional code information, so that the related two-dimensional code information can be conveniently and quickly extracted when needed later, regulated and controlled according to the related information, and different instructions are sent.
When the control center receives the two-dimension code information, the control center sends out an instruction to drive the stacker crane 5 to work, the prefabricated part is transported from the underground maintenance entering station to the internal supporting area of the stacker crane 5, then is vertically transported to the underground from the ground, and then is transported to one of the inlet positions of the maintenance bin according to the instruction of the control center.
When the signal receiver 6 at the inlet position of the curing bin receives the detection signal sent by the die table 1, that is, the die table 1 is conveyed to the inlet position, a gate needs to be opened, the curing bin is fed into the curing bin for curing, then the signal receiver 6 feeds back the detection signal to the second control unit of the inlet of the curing bin, the second control unit sends out an instruction to the corresponding inlet gate switch, and one inlet gate corresponding to the signal receiver 6 is opened.
When the inlet gate at the corresponding inlet position of the curing bin is opened, the stacker crane 5 is matched with the driving wheel 3 and the travelling wheel 4 on the automatic assembly line corresponding to the corresponding inlet position in the curing bin to send the die table 1 to the corresponding automatic assembly line, and the die table 1 continuously moves forwards along with the automatic assembly line. When the die table 1 is completely fed into the curing barn, the second control unit sends out an instruction to open and close the inlet gate of the inlet gate switch.
The die table 1 sequentially passes through the curing bins in and out: the stacker crane 5, the inlet channel, the ferrying station, the common channel, the ferrying station on the other side and the outlet channel return to the stacker crane 5 again. I.e. carried by the palletizer 5 into the inlet aisle, continuously moved forward on the inlet aisle until entering the ferrying station, laterally moved to the common aisle on the ferrying station, then continuously advanced on the common aisle in a direction 180 ° opposite to the previous direction of movement of the inlet aisle, then, with the advancing movement reaching the ferrying station on the other side, likewise laterally moved to the outlet aisle, continuously moved on the outlet aisle in the same direction as the previous direction of movement of the inlet aisle until reaching the curing bin outlet, discharged from the outlet and returned again to the palletizer 5. The curing of the prefabricated component is completed, the moving process of the die table 1 in the curing bin is the curing process, and the time from entering the bin to exiting the bin is the curing time. And then the stacker crane 5 lifts and conveys the die table 1 back to the ground, enters an underground curing kiln-discharging station, queues up to enter a die-removing station, and removes edges of the prefabricated components on the die table 1 in the die-removing station, so that after die removal is completed, the production and manufacturing processes of one prefabricated component are all completed, and the prefabricated components can be conveyed to leave a factory.
The channel of the automatic assembly line is divided into a plurality of units along the moving direction of the die table, each unit comprises a plurality of driving wheels 3 and a plurality of travelling wheels 4, and the driving switches of the driving wheels 3 under each unit are interlocked, namely, the driving switch of any driving wheel in one unit is started and stopped, and the driving switches of all driving wheels in the unit are simultaneously driven to be started and stopped. The driving switch comprises a manual starting switch and an automatic control starting switch. Typically, one of the die stations 1 is sized to cover exactly one cell's channel. Preferably, each unit comprises 3 said drive wheels. The forward movement of the mould table 1 by one unit is accomplished by the co-driving of the interlocking driving wheels 3 of the underlying units and the interlocking driving wheels 3 of the preceding unit. The die table 1 is provided with inductors 2 at the front and rear ends in the moving direction, and the inductors are connected to a first control unit on the motor of the driving wheel 3 in a communication manner. The sensor 2 is a radar or laser emitting and receiving device. The sensor 2 can continuously send out a detection signal, receive and process information when the detection signal bounces back when encountering an obstacle, and make judgment and send out instructions. When the distance between the obstacle and the obstacle is far and is not in the radiation range of the inductor 2, the inductor 2 cannot receive the rebound signal, and the normal condition is judged; when the distance between the obstacle and the obstacle is short, and the radiation range of the sensor 2 is within, the sensor 2 receives the rebound signal, judges that the obstacle is abnormal, sends out an obstacle signal, radiates to the periphery, transmits the obstacle signal to the peripheral control unit I, informs the obstacle, so that the control unit sends out an instruction to turn on the automatic control switch, simultaneously stops all driving wheels of the unit, and the die table 1 stops moving. The control system is an anti-collision system, so that the situation that the die table 1 is bumped when the die table 1 is suspended can be avoided, the possibility of damage to the prefabricated parts is reduced, the prefabricated parts are prevented from being piled up, and the operation of a production line is prevented from being influenced.
The induction and radiation range of the inductor 2 on the die table 1 is 0.5-1 m, preferably the induction and radiation range of the inductor 2 is 0.5 m. Since the movement of the mold table 1 is driven by the driving wheels of the adjacent two unit passages, and the radiation range of the sensor 2 is larger than the distance between the two unit passages, when an obstacle is encountered, such as a person standing by mistake in the advancing direction of the mold table 1 and being close to the distance, the mold table 1 is prevented from colliding with the person, and when the mold table 1 needs to be suspended, the driving wheel 3 of the current unit passage of the mold table 1 and part or all of the control units of the driving wheel 3 of the previous unit passage receive fault signals, and all of the driving wheels of the two units are controlled to stop driving, so that the mold table 1 can be stopped in place in time. When the person leaves the forward passage of the die table 1 or the die table 1 positioned in front has continued to advance, the die table 1 stopped in place needs to be moved again, the manual switch can be started manually on site or can be started through remote control of the control center.
The curing mode adopts the principle of first-in first-out, namely, prefabricated components cured by the curing bin are firstly cured, and the prefabricated components are firstly discharged from the curing bin. In addition, because the information of each prefabricated part can be collected and recorded and processed by the control center, and the layout of the underground maintenance warehouse is designed, the movement track of each mould platform (1) carrying the prefabricated parts can be planned in advance, the carrying route can only go forward and not go backward, except for realizing the ferrying between an inlet channel and an outlet channel and a common channel through a ferrying station, the mould platform can not go from one inlet channel to the other inlet channel until the mould platform is carried to the tail end after the channel is initially accessed to the selected inlet channel or outlet channel. Therefore, after the control center records all the die table information entering the curing barn, the control center can grasp the position of the die table 1 according to the advancing route of the die table 1, the entering sequence of the die table 1, the curing time and the moving speed of the respective moving pipelines, when encountering the special prefabricated part to be preferentially taken out, the route can be changed, the least number of channels of the mould table 1 can be walked, but the mould table 1 can not be directly taken out, because the die table 1 must travel through all the channels to be taken out of the curing barn when entering the curing barn, and simultaneously moves one by one, confusion is avoided, the mould table 1 to be preferentially taken out must wait for all the other mould tables 1 in its movement track to be taken out of the warehouse, it can be taken out of the warehouse, for example, one of the molding tables 1 enters the second inlet channel according to the planned route, and is informed of the need to take out a certain prefabricated part on the molding table 1 as soon as possible, so that the operator can further determine the position of the molding table through the data of the control center, because the previous route, except for the outlet passage, may have a variety of options, the ferry station and the common passage are both a single route, so that the operator can remotely control and pause the movement of the mould tables on other inlet channels through the control center, so that the mould table 1 of the second inlet channel keeps moving, sequentially passes through the first ferrying station and the common channel, and the other die tables 1 are transversely transferred to the outlet channels with a large number of die tables on the ferrying station on the other side, so that the die tables 1 needing to be preferentially taken out enter the outlet channel with the least die tables, and then are taken out of the warehouse and conveyed to the ground by the stacker 5.
