Description

Technical Field

[0001] The utility model relates to the technical field of ground pile demolition equipment, in particular to a ground pile demolition device. Background Art

[0002] Ground piles are common foundation structures in construction projects. Ground piles are used to support and stabilize buildings. There is a part of the cast-in-place ground pile that is higher than the standard ground. After the surrounding ground is leveled, the cast-in-place ground pile above the ground needs to be demolished.

[0003] The existing ground pile demolition device forms a ring structure through the connection of two side ear blocks. The two side ear blocks and the top of the ground pile demolition structure are at the same horizontal plane. When dealing with continuously adjacent ground piles with a short distance, the two side ear blocks will be blocked by the adjacent ground piles and cannot descend, resulting in the inability to demolish continuously adjacent ground piles and being unable to be compatible with the demolition work of continuously adjacent ground piles. Summary of the Invention

[0004] An embodiment of the present disclosure relates to a ground pile demolition device. The upper connecting block and the upper connecting frame body slide to adjust the distance, thereby adjusting the length of ground pile demolition. The main telescopic cylinder moves down to the lower part of the upper connecting frame body. The space between adjacent main telescopic cylinders will not be occupied by the upper connecting frame body. The space between adjacent main telescopic cylinders can accommodate closely adjacent ground piles, realizing the compatibility of the demolition work of closely adjacent ground piles and better adapting to the demolition work where the interval space between ground piles is smaller than the main telescopic cylinder.

[0005] In a first aspect of the present disclosure, a ground pile demolition device is provided, which specifically includes: a main telescopic cylinder, a lower frame body, and an upper connecting frame body. The front part of the main telescopic cylinder is provided with a lower frame body, and an upper connecting frame body is arranged above the lower frame body. The telescopic rod of the main telescopic cylinder is fixed with a demolition top head, and an outer flange is fixed to the front part of the main telescopic cylinder.

[0006] In at least some embodiments, the outer flange and the lower frame body are bolt-fixed, and the demolition top head penetrates through the lower hole position of the lower frame body.

[0007] In at least some embodiments, an upper connecting block is welded and fixed to the upper part of the lower frame body. The upper connecting block is provided with through bolt connection holes arranged at intervals in an array. An outer sliding frame is fixed to the front side of the lower frame body. A lower sliding block slides on the lower part of the outer sliding frame, and an upper support spring is fixed to the top of the lower sliding block.

[0008] In at least some embodiments, the upper end of the upper support spring is fixedly connected to the outer sliding frame.

The upper support spring supports the lower part of the lower sliding block to keep in contact with the upper part of the demolition top head. The lower sliding block blocks and cleans the debris on the upper part of the demolition top head.

[0009] In at least some embodiments, the lower part of the sliding block fits slidably with the upper part of the removal head, and the upper connecting block, the lower frame body, and the main telescopic cylinder move downward synchronously away from each other to adjust the length of the ground pile removal. When the main telescopic cylinder moves downward to the lower part of the upper connecting frame body, the space between adjacent main telescopic cylinders will not be occupied by the upper connecting frame body, and the space between adjacent main telescopic cylinders can accommodate closely arranged ground piles. The upper connecting block is slidably inserted and connected to the lower part of the upper connecting frame body.

[0010] In at least some embodiments, an outer connecting frame is fixedly welded to one side of the upper connecting frame body, a middle connecting frame is fixedly welded to the other side of the upper connecting frame body, a lower fixing bolt penetrates through the lower part of the upper connecting frame body, and through connection holes are arrayed on both the outer connecting frame and the middle connecting frame.

[0011] In at least some embodiments, the bolt connection hole is connected through the lower fixing bolt.

Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1: Please refer to Figures 1 to 6 :

[0028] The present utility model provides a ground pile demolition device, comprising: a main telescopic cylinder 1, a lower frame body 2 and an upper connecting frame body 3. A demolition head 101 is fixed to the telescopic rod of the main telescopic cylinder 1, and an outer flange 102 is fixed to the front part of the main telescopic cylinder 1. The outer flange 102 and the lower frame body 2 are bolted together. The demolition head 101 penetrates through the lower hole position of the lower frame body 2. The front part of the main telescopic cylinder 1 is provided with the lower frame body 2. An upper connecting block 201 is welded and fixed to the upper part of the lower frame body 2. The upper connecting block 201 is provided with through bolt connection holes 202 arranged at intervals in an array. An outer sliding frame 205 is fixed to the front side of the lower frame body 2. A lower sliding block 203 slides on the lower part of the outer sliding frame 205. An upper support spring 204 is fixed to the top of the lower sliding block 203. An upper connecting frame body 3 is arranged above the lower frame body 2. An outer connecting frame 301 is welded and fixed to one side of the upper connecting frame body 3. A middle connecting frame 302 is welded and fixed to the other side of the upper connecting frame body 3. A lower fixing bolt 303 penetrates through the lower part of the upper connecting frame body 3. The outer connecting frame 301 and the middle connecting frame 302 are both provided with through connection holes 304 arranged in an array. The bolt connection holes 202 and the lower fixing bolt 303 are connected through. The outer connecting frame 301 of the upper connecting frame body 3 and the middle connecting frame 302 of another upper connecting frame body 3 are slidably inserted. The through connection holes 304 between the outer connecting frame 301 of the upper connecting frame body 3 and the middle connecting frame 302 of another upper connecting frame body 3 are aligned and penetrated and connected by the lower fixing bolt 303, forming the upper connecting frame body 3 into an annular structure. The upper connecting frame body 3 surrounds the outside of the ground pile to carry out the demolition work.

[0029] In the embodiment of the present disclosure, the upper end of the upper support spring 204 is fixedly connected to the outer sliding frame 205. The upper support spring 204 supports the lower sliding block 203 to move downward. The lower part of the upper support spring 204 supports the lower sliding block 203 to keep in contact with the upper part of the demolition head 101. The lower sliding block 203 blocks and cleans the debris on the upper part of the demolition head 101, preventing the debris generated by the demolition of the ground pile from entering the hole position of the lower frame body 2 along with the demolition head 101, and avoiding the wear of the demolition head 101 caused by the debris in the hole position of the lower frame body 2.

[0030] In the embodiment of the present disclosure, the lower part of the lower sliding block 203 is in sliding contact with the upper part of the demolition head 101. The upper connecting block 201 moves downward away from the lower frame body 2 and the main telescopic cylinder 1 synchronously, adjusting the length of the ground pile demolition. When the main telescopic cylinder 1 moves downward to the lower part of the upper connecting frame body 3, the space between adjacent main telescopic cylinders 1 will not be occupied by the upper connecting frame body 3. The space between adjacent main telescopic cylinders 1 can accommodate closely arranged ground piles, realizing the compatibility of the demolition work of closely arranged ground piles. The upper connecting block 201 and the lower part of the upper connecting frame body 3 are slidably inserted and connected.

[0031] Embodiment 2: On the basis of Embodiment 1, the lower slider 203, the upper support spring 204, and the outer sliding frame 205 are not provided. The omission of the lower slider 203, the upper support spring 204, and the outer sliding frame 205 reduces the number of structural components, reduces the assembly difficulty, reduces the overall cost, and reduces the equipment selling price.

[0032] Working principle of this embodiment: Multiple upper connecting frame bodies 3 are slidably inserted and aligned through the outer connecting frame 301 and the middle connecting frame 302. The larger the diameter of the ring formed by more upper connecting frame bodies 3, the more adaptable it is to the sizes of different ground piles. The through connection holes 304 between the outer connecting frame 301 and the middle connecting frame 302 are aligned and fixed by passing through the lower fixing bolts 303, forming an annular structure with the upper connecting frame bodies 3. The upper connecting frame bodies 3 surround the outside of the ground pile. The top ring of the upper connecting frame body 3 is connected to the hoisting chain of the excavator. The upper connecting block 201 and the upper connecting frame body 3 slide to adjust the distance. The bolt connection holes 202 at different positions of the upper connecting block 201 are fixed by passing through the lower fixing bolts 303 to fix the distance between the upper connecting block 201 and the upper connecting frame body 3. The upper connecting block 201 moves downward away from the lower frame body 2 and the main telescopic cylinder 1 synchronously to adjust the length of the ground pile removal. When the main telescopic cylinder 1 moves downward to the lower part of the upper connecting frame body 3, the space between adjacent main telescopic cylinders 1 will not be occupied by the upper connecting frame body 3. The space between adjacent main telescopic cylinders 1 can accommodate closely arranged ground piles, realizing the compatibility with the removal work of closely arranged ground piles, better adapting to the removal work where the interval space of the ground piles is smaller than the main telescopic cylinder 1, and avoiding the situation where the upper connecting frame body 3 is between the main telescopic cylinders 1, and the ground piles on both sides of the closely arranged ground piles directly contact and support the upper connecting frame body 3, preventing the main telescopic cylinder 1 from contacting the ground pile. The main telescopic cylinder 1 is connected to the hydraulic equipment through pipelines. The main telescopic cylinder 1 supports the removal head 101 to move and contact the ground pile. The annular removal head 101 contacts the outside of the ground pile in an annular shape. Under the pressure of the main telescopic cylinder 1, the removal head 101 directly crushes the concrete of the ground pile, realizing the separation of the concrete and the internal steel bars of the ground pile. Then, the ground pile fragments above the removal head 101 are synchronously moved to the waste position. The main telescopic cylinder 1 shortens to drive the removal head 101 to retreat, and the ground pile fragments above the removal head 101 fall off, which is faster than manual operation by personnel.

[0033] During the process of the removal head 101 retreating, the lower slider 203 slides and fits with the removal head 101. The lower slider 203 blocks and cleans the upper fragments of the removal head 101, preventing the fragments generated during the ground pile removal from entering the hole position of the lower frame body 2 along with the removal head 101, avoiding additional wear of the removal head 101 caused by the fragments of the ground pile removal, and better protecting the removal head 101.
