[0002] Side trenches, power cable troughs, communication and signal cable troughs are required on both sides of the tunnel, and a central drainage ditch is set in the middle of the tunnel. In order to strengthen the adhesion between the cable trough and the tunnel, the smooth base surface needs to be roughened to improve the adhesion of the mortar.

[0019] 5. When the lifting plate drives the first chiseling assembly to descend for the chiseling operation, it will drive the reinforcement mechanism to move downward, first making the stabilizing wheel contact with the bottom of the cable groove, and before the first chiseling assembly descends into place, the slide bar will shrink into the sleeve and squeeze the spring. Under the action of the spring force, the stabilizing wheel can make the contact with the bottom of the cable groove more closely. Without affecting the movement of the device, the stabilizing wheel can effectively increase the friction between the device and the ground, avoid lateral displacement of the casing when the chiseling mechanism is in action, and improve the operation stability of the device.

The chiseling mechanism includes a first chiseling assembly 41 and a second chiseling assembly 42, and a slide rail (not shown in the figure) is installed in the vertical direction inside the housing 1, so that the lifting plate 2 can slide up and down in the housing 1. The first chiseling assembly 41 is installed at the bottom of the lifting plate 2, and a lifting drive assembly for driving the lifting plate 2 to move up and down is installed on the housing 1. The lifting drive assembly includes a first screw rod 31 horizontally installed on the housing 1 above the lifting plate 2, and the first screw rod 31 is connected to the power of the first motor.

And the two first connecting rods 33 are arranged between the lifting plate 2 and the first screw rod 31 in an inverted eight shape. When the first motor drives the first screw 31 to rotate, the first sleeves 32 sleeved on the positive and negative threads will move away from or close to each other, and the first connecting rod 33 drives the lower lifting plate 2 to rise or fall, thereby driving the first chiseling component 41 and the second chiseling component 42 on the lifting plate 2 to move up and down, wherein the first chiseling component 41 at the bottom of the lifting plate 2 can perform chiseling construction on the bottom contact of the cable trench.

[0023] The top surface of the lifting plate 2 is symmetrically provided with movable plates 5, and the two movable plates 5 are horizontally slidably installed at the two side ends of the lifting plate 2. Specifically, the top surface of the lifting plate 2 is provided with a slide groove 20 which is downward and horizontally penetrated from left to right, and the two movable plates 5 are horizontally slidably arranged on both sides of the inside of the slide groove 20. A horizontal driving assembly for driving the two movable plates 5 to move synchronously is provided in the middle of the movable plate 5. The horizontal driving assembly includes a gear 62, a second motor and two strips 61, and the gear 62 is horizontally rotatably installed at the bottom of the slide groove 20, and the gear 62 is connected to the power of the second motor. The two parallel strips 61 are horizontally movable and arranged at the front and rear sides of the gear 62, and the ends of the two strips 61 are respectively fixedly connected to the corresponding movable plates 5. The sides of the two strips 61 which are close to each other are provided with a rack 611 which meshes with the gear 62.

A long strip-shaped limiting hole 610 is opened in the middle of the strip plate 61 along its length direction, and the limiting rod 21 fixed at the bottom of the slide groove 20 is slidably clamped in the limiting hole 610. The limiting rod 21 can effectively limit the horizontal movement of the strip plate 61 to the left and right, thereby improving the stability of the strip plate 61 when sliding left and right.

[0024] A locking assembly for locking the horizontal driving assembly is also installed at the bottom of the slide 20.

The abutment blocks 81 are provided with meshing teeth 811 meshing with the racks 611 on the side close to the strip 61. A first spring 82 is fixed horizontally at the bottom of the slide 20 on both sides of each abutment block 81. The first spring 82 abuts against the side of the abutment block 81 away from the strip 61. Under the elastic force of the first spring 82, the two abutment blocks 81 are pushed to move closer to each other and away from the strip 61. The telescopic cylinder 83 is horizontally arranged on one side of the two abutment blocks 81, and the extrusion block 84 is fixed on the piston rod of the telescopic cylinder 83. The head of the extrusion block 84 is provided with a triangular tip, which is arranged between the two abutment blocks 81 and its two side inclined surfaces slide and abut against the two abutment blocks 81. Through the extension action of the telescopic cylinder 83, the extrusion block 84 is pushed to move toward the middle of the two abutment blocks 81. Through the cooperation of the two inclined surfaces on the abutment block 81, the extrusion block 84 can be pushed to both sides under the sliding limit of the guide rail 22 to squeeze the spring and move close to the strip plate 61, so that the engaging teeth 811 on the extrusion block 84 are engaged with the rack 611 on the strip plate 61, and then the strip plate 61 and the movable plate 5 are locked, so as to avoid the displacement and shaking of the movable plate 5 during the roughening operation of the second roughening assembly 42 on the movable plate 5, which affects the stability of the device.

[0025] The outer edge of the movable plate 5 is rotatably connected with the rotating plate 51 in the vertical direction, the second chiseling assembly 42 is installed on the outer end surface of the movable plate 5, and a support assembly for supporting and fixing the rotating plate 51 is installed on the movable plate 5.

The third motor 73 drives the second screw rod 71 to rotate, and the rotating plate 51 is pushed to rotate around the hinge through the second connecting rod 74, so that the inclination angle of the second chiseling assembly 42 on the rotating plate 51 can be adjusted, so that the second chiseling assembly 42 can effectively cooperate with the side wall of the cable groove, thereby effectively improving the chiseling quality.

[0026] A reinforcement mechanism 9 is also installed at the bottom of the lifting plate 2. The reinforcement mechanism 9 includes a plurality of stabilizing wheels, a sleeve 91 and a slide bar 92. The sleeve 91 is vertically installed at the bottom of the lifting plate 2. One end of the slide bar 92 is slidably sleeved in the sleeve 91 and fixed with a limit block 93 that slides with the inner wall of the sleeve 91. The stabilizing wheel is installed at the other end of the slide bar 92. A second spring 94 is arranged in the sleeve 91 to abut against the limit block 93. When the lifting plate 2 drives the first haircutting assembly 41 to descend for haircutting operation, it will drive the reinforcement mechanism 9 to move downward, firstly making the stabilizing wheel contact with the bottom of the cable groove. Before the first haircutting assembly 41 descends to its place, the slide bar 92 will shrink into the sleeve 91 and squeeze the second spring 94. Under the elastic force of the second spring 94, the stabilizing wheel can abut against the bottom of the cable groove more closely. Without affecting the movement of the device, the stabilizing wheel can effectively increase the friction between the device and the ground, avoid the lateral displacement movement of the housing 1 when the haircutting mechanism is in action, and improve the operation stability of the device.

[0027] When using the construction device provided by the present invention, the lifting plate 2 is driven downward by the lifting drive assembly, and the first chiseling assembly 41 is driven downward to be installed in place, and the stabilizing wheel of the reinforcement mechanism 9 is abutted against the cable groove to improve the movement stability of the device; then the horizontal driving assembly is used to drive the moving plate 5 to move to both sides, and the support assembly is adjusted to drive the rotating plate 51 to rotate, so that the second chiseling assembly 42 on the rotating plate 51 cooperates with the side wall of the cable groove, and the moving plate 5 is locked by the locking assembly. Then, under the electric drive of the driving wheel 11, the device moves in the cable groove, and the bottom and side walls of the cable groove are chiseled and constructed at the same time by the chiseling mechanism.
