[0052] Reference Figure 1 and Figure 2 As shown, this invention discloses a basement roof demolition device, comprising:

[0053] Bracket 100;

[0054] The first limiting component 200 is mounted on the bracket 100. The first limiting component 200 is provided with a limiting groove 210. The groove of the limiting groove 210 is vertically oriented. The limiting groove 210 is adapted to the top tube 800 to be removed so as to be locked onto the vertical top tube 800.

[0055] The second limiting component 300 is disposed on the bracket 100 and located below the first limiting component 200. The second limiting component 300 is provided with a connecting hole 310 for connecting the sling 400.

[0056] Reference Figure 3 As shown, the present invention also discloses a basement roof demolition system, including the aforementioned basement roof demolition device, and...

[0057] Sling 400 is connected to connection hole 310 and can be tied to the jacking pipe 800 to be removed;

[0058] The power unit 600 has a horizontal motion drive seat 610 and a lifting drive seat 620, which can drive the basement roof demolition device to move up and down.

[0059] Reference Figures 4 to 7 As shown, the present invention also discloses the steps for dismantling the backfill components using the aforementioned basement backfill removal system, specifically:

[0060] S100: The bracket 100 is fixedly installed on the lifting drive seat 620. Under the cooperation of the horizontal motion drive seat 610 and the lifting drive seat 620, the limiting groove 210 is stuck on the vertical return pipe 800, restricting the return pipe 800 from tilting to both sides.

[0061] S200: Connect the sling 400 to the connection hole 310 and secure it to the jacking pipe 800 to be removed;

[0062] S300: Cut off the upper end and lower end of the return pipe 800;

[0063] S400: Under the action of the horizontal motion drive seat 610, the power unit 600 moves in the direction away from the opening of the limit groove 210. At the same time, the lifting drive seat 620 drives the bracket 100 to descend, so that the return pipe 800 gradually lies flat.

[0064] In this embodiment, the bracket 100 is made of locally sourced materials such as 150*100*8 square tubing, 10# channel steel, 25mm round steel, and 12mm thick scrap steel plates, which are then joined together by welding. It features readily available materials and a simple structure.

[0065] Combination Figures 3 to 7As shown, during use, the power unit 600 lifts the support 100, causing the limiting groove 210 to engage at 2 / 3 of the length of the return pipe 800. The sling 400 is connected to the connecting hole 310 and secured to the return pipe 800 to be dismantled. Then, the upper end 810 and lower end 820 of the return pipe 800 are cut off. Under the action of the lifting drive seat 620 and the horizontal movement drive seat 610, the support 100 is lowered slightly and moved backward, causing the return pipe 800 to gradually lie flat. The return pipe 800 is placed on the ground, the power unit 600 and the support 100 are separated, and the return pipe 800 is transported to the stacking position, completing the single-pipe dismantling. The remaining return pipes 800 are dismantled in sequence. The limiting groove 210 engages the length of the return pipe 800 to prevent it from tilting to the left or right. By tying the jacking pipe 800 with the sling 400, the jacking pipe 800 is tilted in the direction of the sling 400's pull.

[0066] During the dismantling process, the jacking pipe 800 is supported by a basement jacking demolition device. This support prevents the jacking pipe 800 from tipping over, thus eliminating the lateral impact force generated during its removal and ensuring the safety of surrounding facilities and personnel. The basement jacking demolition device, in conjunction with the power unit 600, increases the utilization rate of machinery compared to manual labor, significantly improving demolition efficiency and reducing costs. During demolition, there is no need to weld lifting lugs or other temporary measures onto the jacking pipe 800, greatly improving work efficiency. Furthermore, there is no need to increase the area of ​​the top embedded plate for support, reducing the use of permanent temporary measures and lowering construction costs.

[0067] Reference Figure 1 and Figure 2 As shown, the bracket 100 includes a horizontal bracket 110 and a vertical bracket 120. The horizontal bracket 110 is horizontally arranged, and the vertical bracket 120 is vertically arranged on the horizontal bracket 110. The first limiting component 200 and the second limiting component 300 are installed on the vertical bracket 120.

[0068] In this embodiment, the support 100 consists of a horizontal frame 110 and a vertical frame 120, and the horizontal frame 110 can be placed horizontally on the ground. Figure 3 and 7 As shown, during the disassembly of the jacking pipe 800, the horizontal frame 110 allows the support 100 to be placed stably on the ground. The vertical frame 120 provides installation positions at different heights, providing the necessary installation positions for the first limiting component 200 and the second limiting component 300 at different installation heights.

[0069] Reference Figure 1 and Figure 2As shown, the horizontal frame 110 includes two square tubes 111, which are arranged horizontally. The vertical frame 120 is installed at one end of the two square tubes 111. The end of the square tube 111 away from the vertical frame 120 is provided with an insertion lifting hole 1111, which extends along the length of the square tube 111.

[0070] The lifting drive seat 620 includes a lifting rail and a plug. The lifting rail is set on the horizontal motion drive seat 610, and the plug is set on the lifting rail. It can move up and down along the lifting rail, and the plug can be inserted into the corresponding insertion lifting hole 1111.

[0071] In step S100, the bracket 100 is fixedly installed on the lifting drive seat 620 by inserting the insert pin into the corresponding insertion lifting hole 1111.

[0072] In this embodiment, the horizontal frame 110 includes two square tubes 111, and the insertion lifting holes 1111 on the square tubes 111 can provide a point of action for the lifting of the power unit 600. Specifically, refer to... Figure 3 and Figure 4 As shown, the power unit 600 is inserted into the insertion lifting hole 1111 via the insertion post 621, and drives the bracket 100 to move up and down via the insertion post 621. The horizontal frame 110 also includes a connecting pipe connecting the two square tubes 111 to strengthen the overall structure.

[0073] In this embodiment, the power unit 600 achieves the lifting and lowering of the bracket 100 by means of the insertion post 621 cooperating with the insertion lifting hole 1111. In other embodiments, the power unit 600 can also be in other forms, such as by means of gripping with a robotic arm, under the grip of the robotic arm, driving the bracket 100 to move up and down.

[0074] Reference Figure 3 As shown, the square tube 111 is provided with a lifting lug 112, and the lifting lug 112 is provided with an ear hole 1121. The lifting lug 112 is located near the insertion lifting hole 1111.

[0075] Step S100 also includes a lifting lug 112 wire rope. One end of the lifting lug 112 wire rope is connected to the lifting rail, and the other end is suspended from the ear hole 1121. The lifting lug 112 wire rope and the insertion column rise and fall together.

[0076] In this embodiment, by providing the lifting lug 112, when the power unit 600 is inserted into the insertion lifting hole 1111 via the insertion post 621, the power unit 600 is then connected to the lifting lug 112 via the lifting lug wire rope 130. Under the traction of the lifting lug wire rope 130, the stability of the support 100 during the lifting process is improved, preventing the insertion post 621 from detaching from the insertion lifting hole 1111.

[0077] The lifting drive seat 620 includes a plug 621 and a lifting rail. The plug 621 is installed on the lifting rail and can move up and down on the lifting rail.

[0078] Specifically, the power unit 600 is a forklift. The forklift is used to move and lift the support 100.

[0079] Reference Figure 1 and Figure 2 As shown, the vertical frame 120 is provided with a first crossbeam 121 and a second crossbeam 122, which are arranged horizontally in the upper and lower directions. A first limiting component 200 is provided on the first crossbeam 121, and a second limiting component 300 is provided on the second crossbeam 122.

[0080] In this embodiment, by setting the first crossbeam 121 and the second crossbeam 122, the strength structure of the vertical frame 120 is strengthened, while providing an installation position for the first limiting component 200 and the second limiting component 300.

[0081] Reference Figure 1 and Figure 2 As shown, it also includes a third limiting component 500, which is mounted on the bracket 100 and located below the second limiting component 300. The third limiting component 500 is provided with a support groove 510, which is vertically oriented. The support groove 510 is adapted to the top pipe 800 to be removed so as to abut against the vertical top pipe 800.

[0082] In step S100, the support groove 510 rests on the body of the vertical return pipe 800.

[0083] In this embodiment, combined with Figure 5 As shown, the support groove 510 of the third limiting component 500 rests against the middle of the return tube 800. Combined with the pulling effect of the sling 400, the lever effect ensures that when the power device 600 retracts, the top of the return tube 800 tilts in the direction of the retraction of the power device 600. At the same time, the friction between the sling and the tube restricts the return tube 800 from slipping. If the third limiting component 500 is not set, the return tube 800 may move together with the sling 400 under the pull of the sling 400. That is, before the return tube 800 tilts, the lower end of the return tube 800 moves with the sling 400, causing the return tube 800 to be unable to change from an upright state to an inclined state, or the time to change from an upright state to an inclined state to a more prolonged state.

[0084] Reference Figure 1 and Figure 2As shown, the opening of the support groove 510 is an arc-shaped opening. In this embodiment, the return pipe 800 is mainly a cylindrical pipe. In order to better fit the support groove 510 and the return pipe 800 together, the opening of the support groove 510 is set as an arc-shaped opening, which can better support the return pipe 800.

[0085] Reference Figure 1 and Figure 2 As shown, the first limiting component 200 includes two limiting rods 220, which are spaced apart to form a limiting groove 210. In this embodiment, the two limiting rods 220 are welded to the first crossbeam 121, and the limiting groove 210 is formed between the two limiting rods 220. The return pipe 800 is stuck in the limiting groove 210, which can restrict the movement of the limiting groove 210.

[0086] It also includes step S500, in which the return pipe 800 is placed on the ground, the forklift and the support 100 are separated, the forklift takes away the return pipe 800 placed on the ground and transports it to the stacking location.

[0087] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
