Technical Field

[0001] This utility model belongs to the technical field of TRD construction equipment, and in particular relates to a cutting box lifting auxiliary device. Background Technology

[0002] The TRD method uses a TRD machine-driven cutting box to cut the ground. After the operation is completed, the cutting box needs to be pulled out of the ground. Currently, the following two methods are used in the pulling process: First, a crane is used to pull out multiple sections of the cutting box as a whole. The length of the multiple sections of the cutting box is relatively long, which is prone to the safety problem of the crane tipping over. Second, a crane lifts one section of the cutting box and then a forklift is used to support the lower sections of the cutting box. Then the top section of the cutting box is disassembled. This method requires frequent movement of the forklift, which can easily scratch the cutting box. It also requires a large working space, which affects the safety of the operation.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 9 As shown, a cutting box 3 lifting auxiliary device includes two positioning components. Each positioning component includes a base 1, a movable plate 2, and a connecting plate. The movable plate 2 is movably connected to the base 1, and a positioning plate 201 corresponding to the positioning groove 301 of the cutting box 3 is fixed on the movable plate 2. There are two positioning components, which are connected by a connecting rod 4. One end of the connecting rod 4 is hinged to one of the positioning components, and the other end of the connecting rod 4 is detachably connected to the other positioning component.

[0022] Two parallel sliding rods 202 are fixedly mounted on the end face of the movable plate 2 away from the positioning plate 201. The sliding rods 202 are perpendicular to the movable plate 2. A support rod 101 corresponding to one end of the sliding rod 202 is fixedly mounted on the base 1. The upper end face of the support rod 101 supports the lower end face of the sliding rod 202. The movable plate 2 is movably connected to the base 1 along the length direction of the sliding rod. A limiting rod 6 corresponding to the sliding rod 202 is fixedly mounted on the base 1. The limiting rod 6 limits the upper end face of the sliding rod 202 away from the positioning plate 201. A driving assembly for driving the movable plate 2 to move is fixedly mounted on the base 1.

[0023] The sliding rod 202 has a first limiting hole 203, and the support rod 101 has a limiting groove 102 corresponding to the first limiting hole 203. When the positioning plate 201 is inserted into the positioning groove 301, the limiting pin 8 passes through the first limiting hole 203 and is located inside the limiting groove 102. The limiting pin 8 serves to limit the sliding rod 202.

[0024] A U-shaped steel 204 is fixedly provided on the lower end face of the sliding rod 202. The opening of the U-shaped steel 204 is set downward. A second limiting hole corresponding to the first limiting hole 203 is opened on the U-shaped steel 204. The limiting pin 8 is set through the second limiting hole. The support rod 101 is located inside the two vertical plates of the U-shaped steel 204, and the upper end of the support rod 101 supports the horizontal plate of the U-shaped steel 204; the U-shaped steel 204 plays a guiding role in the movement of the sliding rod 202.

[0025] The base 1 is equipped with rollers 106, which are located inside the two vertical plates of the U-shaped steel 204. The rollers 106 correspond to the positions of the limiting plates and provide support for the sliding rod 202.

[0026] In some embodiments, the drive component is a hydraulic cylinder 5, the housing of which is hinged to the limiting rod 6, and the output shaft of which is hinged to the movable plate 2. In other embodiments, the drive component is a pneumatic cylinder or an electric cylinder. The hydraulic cylinder 5 drives the movable plate 2 to move, improving work efficiency.

[0027] Two mounting plates 103 are fixedly mounted on one end of the base 1 near the positioning plate 201. One mounting plate 103 has a hinge shaft 104 fixedly mounted on it, and the other mounting plate 103 has a screw 105 fixedly mounted on it. One end of the connecting rod 4 has a hinge hole 403, with the hinge shaft 104 located inside the hinge hole 403. The other end of the connecting rod 4 has a strip-shaped connecting hole 401 corresponding to the screw 105. The strip-shaped connecting hole 401 has an opening on the side wall of the connecting rod 4, and its width is greater than the diameter of the screw 105. The connecting nut 7 is threadedly connected to the screw 105. By setting the connecting rod 4, the two positioning components are connected as a whole, improving the structural strength of the device.

[0028] The upper end face of the connecting rod 4 has a circular limiting groove 402 corresponding to the strip-shaped connecting hole 401. The lower end of the connecting nut 7 is fixed with an annular limiting boss 701 corresponding to the circular limiting groove 402. The outer diameter of the annular limiting boss 701 is smaller than the diameter of the circular limiting groove 402 and larger than the width of the strip-shaped connecting hole 401. The annular limiting boss 701 is located inside the circular limiting groove 402. The annular limiting boss 701 plays a limiting role for the connecting nut 7, preventing the screw 105 from disengaging from the strip-shaped connecting hole 401.

[0029] When the positioning component is in a stowed state (e.g.) Figure 5 As shown), the screw 105 is located inside the strip-shaped through hole of the connecting rod 4; the connection in the retracted state is connected to its own screw 105, which not only reduces the length, but also prevents the connecting rod 4 from shaking during movement, thus improving the stability of the transportation process.

[0030] When the two positioning components are connected by the connecting rod 4 (as shown in Figure 1), the screw 105 of the positioning component is located inside the strip-shaped through hole of the connecting rod 4 of the other positioning component.

[0031] The two sides of the positioning plate 201 are chamfered. The chamfered structure plays a guiding role when the positioning plate is inserted into the positioning groove. The width of the positioning plate 201 matches the width of the positioning groove 301, and the thickness of the positioning plate 201 is less than the length of the positioning groove 301.

[0032] The length of the protrusion of the positioning plate 201 from the moving plate 2 is less than the depth of the positioning groove 301, which can prevent the positioning plate 201 from hitting the bottom of the positioning groove 301.

[0033] Work process: When this solution is implemented, the connecting rod 4 of the positioning component is in an active state. The base 1 of the two positioning components is placed on both sides of the cutting box 3. The connecting rod 4 is rotated so that the opening of the strip connecting hole 401 is aligned with the screw 105 of the other positioning component and inserted. Then the connecting nut 7 is tightened and pressed against the upper end face of the connecting rod 4. Using a crane, lift section 31 of the cutting box and move the device so that the positioning plates 201 of the two positioning components are aligned with the positioning slots 301 of the cutting box 3. Then, the output shaft of the hydraulic cylinder 5 extends and drives the positioning plate 201 to insert into the positioning slots 301 of the second section of the cutting box 3. Then, the upper cutting box 3 is disassembled. The positioning plate 201 serves to support the lower cutting box 3. Then, the crane is used to move and lift the cutting box 3 to the designated position. The second section of the cutting box 3 is then lifted, and the positioning slots 301 are pulled out. The above steps are repeated to complete the lifting and pulling operation of the cutting box 3.

[0034] Compared to the traditional method of completely pulling out the lower cutting box 3, or fixing it manually or with a forklift, the lower cutting box 3 is supported by the positioning plate 201, which improves the safety of the operation process.
