[0039] In this embodiment, the third vision sensor rotates 360 degrees driven by the second servo motor for quickly identifying the construction environment and the walking path.

[0040] Embodiment 5

[0041] As Figures 1-6 shown in the figure, sliders 10 are respectively slidably connected to the linear guide rails. The inner ends of the four sliders 10 are connected to a telescopic rectangular frame 11. The outer surface of the telescopic rectangular frame 11 is respectively rotatably connected to each slider 10. The telescopic rectangular frame 11 includes a front half frame body 111 and a rear half frame body 112. Plug rods 115 are respectively connected to the two free ends of the front half frame body. Slots are arranged at the two free ends of the rear half frame body 112. The plug rods are inserted into the slots and are slidably connected to the slots. A first cross bar 117 and a second cross bar 116 are respectively rotatably connected to the inner sides of the front half rectangular frame 111 and the rear half rectangular frame 112.

[0042] As Figures 1-6As shown in the figure, the driving mechanism includes two first lead screws 13 arranged side by side in the front-rear direction at the top of the counterweight block. The top end of the first lead screw 13 is rotatably connected to the top plate, and the bottom end is rotatably connected to the top of the counterweight block 8. First threaded holes 119 are respectively formed in the middle parts of the first cross bar 117 and the second cross bar 116. The two first lead screws 13 respectively pass through the corresponding first threaded holes 119 and are screwed to the first cross bar 117 or the second cross bar 116. Third servo motors 14 are respectively arranged at the upper end of the top plate corresponding to the two first lead screws 13. The third servo motors 14 are electrically connected to the controller through wires.

[0043] As Figures 1-6 shown in the figure, the driving mechanism further includes a fourth servo motor and a second lead screw. Two second lead screws 118 are further arranged between the front end of the first cross bar 117 and the front end of the front half rectangular frame 111. The heads of the two second lead screws 118 abut against each other, and a partition plate 114 is arranged at the abutting position. The front end of the partition plate 114 is fixedly connected to the inner surface of the front end of the front half rectangular frame 111. The rear end of the partition plate 114 is slidably matched with the outer surface of the first cross bar 117.

[0045] In this embodiment, the rotation of the two first lead screws drives the telescopic rectangular frame to lift, so that the up and down movement of the arm rods can be realized. When the heights of the two rear sliders are higher than the heights of the two front sliders, the two arm rods tilt forward and downward. On the contrary, they tilt forward and upward. When the second lead screw rotates, it can drive the arm rods to move left and right, so that the positions of the two arm rods match the form removal positions.

[0046] Embodiment 6

[0047] As Figure 1 、 6As shown, an installation pipe (not marked in the figure) is integrally formed at the front end of the arm rod 18. The force application mechanism is a second electric cylinder 20 disposed in the installation pipe. The cylinder barrel of the second electric cylinder 20 is fixedly connected to the inner wall of the installation pipe. The telescopic end of the second electric cylinder 20 is fixedly connected with a connecting pipe 29 through a tension sensor 27. A fifth servo motor 24 is embedded in the connecting pipe 29. The output shaft of the fifth servo motor 24 is arranged along the axial direction of the connecting pipe 29. An annular limiting block (see Figure 6 shown, not marked in the figure) is integrally formed on the inner wall of the connecting pipe 29 where the outer side of the fifth servo motor 24 is located. A connecting hole 33 is formed in the annular limiting block. The rear end of the wedge-shaped disassembly module 26 is connected with a stop block 30 through a connecting rod 34 passing through the connecting hole 33. The stop block 30 is in close fit with the annular limiting block. A spline groove 31 is arranged at the inner end of the stop block 30. The output shaft of the fifth servo motor 24 is connected with the spline groove 31 through a spline.

[0048] In this embodiment, the rotation of the wedge-shaped disassembly module can be realized through the fifth servo motor 24. The contact situation between the wedge-shaped disassembly module and the template can be detected through the tension sensor. The degree of separation between the template and the component can be identified through the telescopic amount of the second electric cylinder.

[0049] The working principle of the utility model:

[0050] As Figure 7 shown, a structural schematic diagram of the end template of a box girder is given. Of course, it must be noted that the utility model is also applicable to the removal of other types of templates.

[0051] As Figure 4 shown, when removing the template, the equipment body is placed at the working position. The equipment body starts the third vision sensor 16, moves to the front of the template according to the vision information, raises the arm rod to the required height through the driving mechanism, and adjusts the distance and pitching angle between the two arm rods. According to the vision information of the first vision sensor, the controller makes the tips of the two wedge-shaped disassembly modules insert into the two side edges of the template. When needed, start the first servo motor to rotate the arm rod to adapt to the form removal angle. After the wedge-shaped disassembly module clamps the template, the first electric cylinder extends to make the pressure foot press tightly on the ground, and start the second electric cylinder to perform repeated and rapid contraction actions. The contraction amplitude is controlled within the range of 2 - 3 cm.

[0052] Before starting the contraction, the tension sensor needs to detect a certain tension A to prove that the wedge-shaped disassembly module is pressed against the back of the formwork. During this process, the controller identifies the telescopic distance of the second electric cylinder. When the tension A is detected and the telescopic distance becomes shorter, it means that the formwork is pulled away from the component 25, and the pulling distance is equal to the shortening amount B of the telescopic distance. At this time, the controller makes the second electric cylinder extend and makes the tension sensor detect a preset tension C, where the tension C is less than the tension A, which means that the wedge-shaped disassembly module is in contact with the back of the formwork but can slide relatively. Then, the wedge-shaped disassembly module is inserted more inward into the back of the formwork until the tension sensor detects the tension A again due to the extrusion of the component. At this time, the contraction action is continued to be repeated quickly.

[0053] In this way, repeat repeatedly until the wedge-shaped disassembly module is completely inserted into the back of the formwork. Then, according to the visual information detected by the first visual sensor, move the arm up, down, left or right, and cooperate with the control of the angle of the wedge-shaped disassembly module by the fifth servo motor to make the wedge-shaped disassembly module act in a new position, thereby realizing the removal of the entire formwork.
