Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application.

Referring to fig. 1 to 6, the invention provides an assembly type subway station middle plate assembly device, which comprises a movable trolley, a support bracket 2, a point cloud camera 3, an electric sliding frame 4, a distance sensor 5 and a controller.
Wherein the number of the mobile trolleys is two. The two sets of mobile trolleys are oppositely arranged. In this embodiment, the subway station is an assembled structure, and includes a prefabricated inverted arch, side walls on opposite sides of the prefabricated inverted arch, and vaults arranged on the side walls. The middle part of prefabricated inverted arch is equipped with many spinal branch daggers. The support columns are arranged at intervals along the length direction of the subway station. A plurality of support posts are mounted with support beams 61. The prefabricated middle plate 62 is laid on the supporting beam, and two ends of the prefabricated middle plate are lapped on the side walls. The two moving trolleys are respectively arranged on two opposite sides of the supporting beam.
Specifically, a platen 11 is mounted on the top of the mobile carriage. An electric movable table 12 is mounted on the platen 11 so as to be adjustable in position.
The support bracket 2 is disposed above the electric moving table 12. At least four electro-hydraulic jacks are mounted to the electro-mobile platform 12. The electric hydraulic jack is vertically arranged. The telescopic end of the electric hydraulic jack is connected with the support bracket 2 in a spherical hinge manner. At least four electro-hydraulic jacks are provided along the circumferential direction of the support bracket 2. A stopper 24 is formed at one side of the support bracket 2. The support bracket 2 is used to support one end of a prefabricated middle plate 62 of a subway station. The stopper 24 is used to abut against one side of the middle plate 62.
In the present embodiment, the number of electro-hydraulic jacks is four. The four electric hydraulic jacks are arranged in a matrix. The support bracket and the bedplate are arranged at various angles through different expansion and contraction amounts of the plurality of electric hydraulic jacks, and the support bracket is further suitable for posture adjustment of the prefabricated middle plate.
The point cloud camera 3 is mounted to the stopper 24. The point cloud camera 3 is used for acquiring actual point cloud data of the prefabricated middle plate 62.
The point cloud camera is used for detecting the flatness of the prefabricated middle plate and detecting the inclination of the prefabricated middle plate in the length direction (the width direction of the whole subway station).
Specifically, the prefabricated middle plate is a plate body with uniform thickness. The flatness of the upper or lower surface of the prefabricated middle plate is uniform. The point cloud camera collects the assembly flatness of the lower surface of the prefabricated middle plate.
For inclination detection, the point cloud cameras scan the point cloud data of the central line of the prefabricated middle plate in the length direction, and as the position of the cameras corresponding to the prefabricated middle plate is fixed, the distance between each point cloud and the point cloud camera is also a preset theoretical value, and the deviation exists between the preset theoretical value and the actual value, so that the fact that the prefabricated middle plate is inclined is indicated, and the inclination can be calculated by a calculation module of the controller through a corresponding algorithm so as to generate the telescopic action process of the electric hydraulic jack.
The electric skid 4 is slidably provided on a support beam 61 of the subway station. The support beam 61 is for supporting the middle of the prefabricated middle plate 62 and is disposed along the width direction of the prefabricated middle plate 62. Wing rods 43 are respectively connected to opposite sides of the electric sliding frame 4.
The distance sensor 5 is mounted to the wing rods 43 and aligned with a prefabricated middle plate 62 on the support beam 61.
The controller comprises a control module, a detection module and a calculation module. The control module is connected with the electric moving support, the electric hydraulic jack, the point cloud camera 3, the electric sliding frame 4 and the distance sensor 5. The detection module and the calculation module are respectively connected with the control module.
The detection module determines whether the position and posture of the prefabricated middle plate 62 meet the design requirements based on the preset point cloud data and the preset distance value.
When the position and the posture of the prefabricated middle plate 62 do not meet the design requirements, the calculation module calculates the expansion and contraction amount of the electric hydraulic jack based on the preset point cloud data and the preset distance value, and the actual point cloud data and the actual distance value.
The control module controls the position and posture of the at least four electro-hydraulic jacks to adjust the precast middle plate 62 based on the amount of telescoping to meet the design requirements.
In this embodiment, the detection range of the point cloud camera is limited to only the prefabricated middle plate being laid. Because the electric sliding frame can move along the length direction of the supporting beam, the distance sensor can detect the assembly flatness of all paved prefabricated middle plates or paved adjacent prefabricated middle plates. The point cloud camera is used for detecting flatness of a prefabricated middle plate on a support bracket (the prefabricated middle plate is placed on a support beam on the support bracket, and the support bracket is in a state of being not stressed and not separated from the prefabricated middle plate). The distance sensor is used for rechecking the flatness of the prefabricated middle plate.
As a preferred embodiment, the platen 11 is formed with two guide grooves. The opposite sides of the electric moving platform 12 are provided with electric rollers. The electric roller is arranged in the guide groove in a sliding way.

The limiting piece 24 is fixedly arranged at one end of the bottom supporting beam 23.
In the present embodiment, the platen is provided along the width direction of the subway station. The guide groove is provided along the width direction of the platen. The shoulder pole beam is arranged along the length direction of the bedplate. The bottom supporting beams are arranged along the width direction of the bedplate.
Referring to fig. 3, the electric sliding frame 4 includes a base plate 41 and two electric clamping wheels 42.
Specifically, the bottom plate 41 is disposed below the support beam 61. Wing rods 43 are respectively connected to opposite ends of the bottom plate 41.
The two motorized clasping wheels 42 are disposed opposite. The motorized pulley 42 is rotatably mounted on opposite sides of the base plate 41. A clamping space is formed between the two electric clamping wheels 42. The support beam 61 is embedded in the clamping space.
The tread of the electric pinch wheel 42 is laid with an anti-slip layer.
In this embodiment, the anti-slip layer is an elastic rubber layer. The width of the clamping space between the two electric clamping wheels is smaller than that of the supporting beam.
In some embodiments, the bottom of the support beam is lined with magnetic metal strips. The bottom plate is provided with a magnetic attraction piece. The magnetic attraction piece is a magnet. The magnetic attraction piece is magnetically attracted to the magnetic metal strip. After the electric clamping wheel rotates, the electric sliding frame moves along the length direction of the supporting beam, and in the moving process, the magnetic attraction force of the magnetic metal strip and the magnetic attraction piece improves the translation stability of the electric sliding frame.
