The two sliding seats 21 slide in the same direction, and the sliding tracks of the two sliding seats 21 are located on the same straight line. Figure 5Two square holes 115 are respectively provided on the top frame 1, which are respectively penetrated from top to bottom. Slide grooves are provided on both sides of the inner side of the square hole 115. The sliding seat 21 is slidably provided in the square hole 115 to limit the vertical displacement of the slide groove. A telescopic cylinder 116 is provided inside the top frame 1 inside the square hole 115. The telescopic cylinder 116 can be an electric cylinder or a hydraulic cylinder. The output end of the telescopic cylinder 116 is fixedly connected to the sliding seat 21. Under the drive of the telescopic cylinder 116, the displacement of the sliding seat 21 on the top frame 1 can be realized. Two winders 211 are provided on the top of the sliding seat 21. The winders 211 are used to wind up the steel rope 212. Figure 5 and Figure 6 The winding machine 211 winds the steel rope 212 and passes through the bottom surface of the sliding seat 21. The clamping seat 23 is detachably provided with two clamping plates 231 extending downward. The two clamping plates 231 are respectively placed on both sides of the cutting wall block 3. Figure 1 and Figure 7 As shown, two support columns 233 are respectively extended on both sides of the sliding seat 21, two support holes 2312 cooperating with the support columns 233 are arranged on the upper part of the clamping plate 231, and the outer ends of the support columns 233 are connected with locking nuts 234, and a long plate 2313 is extended from the lower part of the clamping plate 231, and a reinforcing plate 2314 is connected between the long plate 2313 and the clamping plate 231, and two support blocks 2315 are further arranged between the long plate 2313 and the clamping plate 231, and the through hole 2311 is arranged on the support block 2315, and the lower end of the clamping plate 231 is provided with a through hole 2311, and the through hole 2311 is penetrated by a support rod 232, as shown in FIG. Figure 4 As shown, the cutting wall block 3 has a square structure of uniform size. During the clamping and removal process, it is cut according to requirements, and after the clamping block is clamped, the through hole 31 of the cutting wall block 3 is opened by drilling equipment at the through hole 2311 of the clamping block. When clamping the cutting wall block 3, the support rod 232 simultaneously passes through the through holes 2311 of the two clamping plates 231 and the through hole 31 opened on the cutting wall block 3. Stopping structures can be set at both ends of the support rod 232 to prevent the support rod 232 from sliding during the clamping process. This clamping plate 231 is provided with a reinforcing plate 2314 and a support block 2315 to provide a strong support structure for the clamping plate 231 to prevent the load-bearing damage of the clamping plate 231; Figure 2 The rotating seat 22 is rotatably arranged at the top of the clamping seat 23. The clamping seat 23 is provided with a motor for driving the rotating seat 22 to rotate. The driving mode is a conventional gear drive mode. The top surface of the rotating seat 22 is engaged with the bottom surface of the sliding seat 21. Figure 5 and Figure 6The specific structure of the chimeric splicing is as follows: six long strip protrusions 213 are provided in a circular array at the bottom end of the sliding seat 21, and six long strip grooves 221 are provided in a corresponding circular array at the top end of the rotating seat 22. The steel rope 212 extends from the protruding surface of the protrusion 213 and is connected to the bottom surface of the groove 221. By chimeric splicing, when the sliding seat 21 is chime-fitted into the rotating seat 22, the sliding seat 21 and the rotating seat 22 are fixedly moved horizontally, and the end of the steel rope 212 is fixedly connected to the rotating seat 22. As the steel rope 212 is extended and retracted, the rotating seat 22 and the clamping seat 23 can be lowered from the bottom side of the sliding seat 21.

[0029] This demolition device is a device that occupies a small space and is suitable for foundation pit construction sites with narrow space. Through the double wall block clamping part 2, the switching clamping of the wall block clamping part 2 and the lowering of the clamping seat 23 can realize the continuous cutting and demolition of the wall block 3; Figure 9-11 The schematic diagram of the demolition device is as follows: first, the middle partition wall is clamped at the top end of the middle partition wall. Fig. 9 , clamp the two wall block clamping parts 2 on the middle partition wall respectively, then drill holes and insert the support rod 232 respectively, connect the clamping seat 23 and the cutting wall block 3 together through the support rod 232, and after the clamping is completed, the wall block can be cut, and the unit cutting wall block 3 to be removed can be separated from the middle partition wall as a whole, and the subsequent removal of the cutting wall block 3 can be started, refer to Fig.10 By moving the wall block clamping part 2, the cut wall block 3 can be separated from the middle partition wall by a certain distance, providing a collision-proof gap for the subsequent rotation of the cut wall block 3, refer to Fig.11 , through the rotation of the rotating seat 22 on the clamping seat 23 on the middle partition wall, the entire top frame 1 and the wall block clamping part 2 clamping the cut wall block 3 are driven to rotate out of the middle partition wall. At this time, the winding machine 211 is lowered, so that the clamping seat 23 drives the cut wall block 3 to move down to the ground, and the removal of a unit of cut wall block 3 is realized at this time; after the cut wall block 3 is unloaded, the wall block clamping part 2 returns to its position, and the rotating seat 22 is continuously rotated to move the wall block clamping part 2 to the cut wall block 3 of the next interval unit. At this time, the middle partition wall position clamped by the wall block clamping part 2 as a fixed position becomes the wall block to be cut next time, and the wall block clamping part 2 of the middle partition wall clamped again becomes the next supporting rotating structure; this device is installed on the top side of the middle partition wall, and through the rotating movable structure, a wall block removal structure in a small space is realized, without involving other equipment such as a crane that cannot be installed in a foundation pit environment; this device can realize the removal of continuous cut wall blocks 3, with a simple construction method and high removal efficiency.

[0030] In a further solution, Figure 1 , Figure 2 and Figure 3As shown, the top frame 1 includes two vertical slides 11, and the vertical slides 11 include an integrally formed horizontal bottom plate 111 and a vertical upright plate 112. A reinforcing support mechanism is provided between the horizontal bottom plate 111 and the vertical upright plate 112 to form a stable triangular support. The two vertical upright plates 112 are vertically slidably connected to each other. Figure 8 The two vertical plates 112 are respectively provided with T-shaped rails 1121 and T-shaped grooves 1122 that cooperate with each other. When the lateral displacement of the two vertical plates 112 is limited, the two vertical plates 112 can move vertically relative to each other. A rack 113 is provided on the side of one of the vertical plates 112, and a motor-driven gear 114 is provided at the bottom of the other vertical plate 112. The gear 114 is meshed with the rack 113. The two sliding seats 21 are respectively slidably arranged on the two horizontal bottom plates 111. The meshing mode of the rack and the gear is a conventional meshing mode. The self-locking structure of the worm gear can be used to realize the motor driving the vertical plates 112 to move, and no relative displacement will occur between the vertical plates 112.

[0031] In this structure, a double wall block clamping structure capable of vertical displacement is provided, such as Fig.12 As shown, this structure can move the clamping part 2 of another wall block downward as a whole when the last cut wall block 3 of a layer of middle partition wall is removed, and clamp the next layer of middle partition wall to achieve the cutting and removal of the last cut wall block 3. By setting this structure, more continuous middle partition wall removal work can be achieved, avoiding the reinstallation of the overall removal device, and is suitable for the removal of middle partition walls at a higher height.
