[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a dismantling frame for concrete pump pipes in high-rise buildings, including a dismantling frame 2. The dismantling frame 2 is placed on the pump pipe dismantling layer, and the pump pipe dismantling layer includes a floor base 3 and a floor top slab 4. The dismantling frame 2 includes a moving component, a lifting component 23, and a lifting component 24. The lifting component 23 is used to lift and install the lifting component 24 on the moving component, and the lifting component 24 is used to lift the pump pipe assembly 1. More specifically, the moving component includes a supporting base plate 21, a dismantling frame connecting plate 22, and two steel support beams 25. The two steel support beams 25 are hinged to the dismantling frame connecting plate 22, and the two steel support beams 25 are respectively fixed to the supporting base plate. At both ends of the top of the 21, the movable component is also provided with U-shaped steel supports 26, which cooperate with two steel support beams 25 to form a pump pipe support groove for limiting the pump pipe assembly 1. The U-shaped steel supports 26 provide temporary and reliable support. Specifically, the U-shaped steel supports 26 are set on the top of the two steel support beams 25, so that the extension direction of the U-shaped steel supports 26 is perpendicular to the extension direction of the steel support beams 25, thereby forming a pump pipe limiting groove. A lifting component 23 is provided on the support base plate 21. The lifting component 23 is connected to the lifting component 24. The lifting component 24 is used to lift the pump pipe assembly 1. A moving wheel 29 is installed at the end of the steel support beam 25 near the support base plate 21.

[0023] Based on the required pipe diameter, wall thickness, and length of each section to be removed, the weight of each section of the pump pipe to be removed is calculated. Based on the weight, a set of pump pipe removal tools is designed. The foldable and retractable dismantling frame 2 is transported to the floor where the pump pipe assembly 1 to be removed is to be transported by a personnel and freight elevator. Generally, the pump pipe assembly 1 is removed from top to bottom. Then, using the movable wheels 29 on the dismantling frame 2, it is dragged to the position of the reserved opening 5 in the floor slab where the pump pipe to be removed is to be removed. The dismantling frame 2 is installed on the pump pipe removal floor, and the pump pipes in the range of 3 to 5 floors below this floor are removed each time.

[0024] The pump pipe assembly 1 includes a pipe body 11, with an upper end connector 12 at the upper end and a lower end connector 13 at the lower end.

[0025] The lifting assembly 23 includes a spiral lifting lower rod 231 and a spiral lifting upper rod 232. The lower end of the spiral lifting upper rod 232 is embedded inside the spiral lifting lower rod 231. The spiral lifting upper rod 232 is driven by a spiral lifting wheel 233. The spiral lifting upper rod 232 can move axially relative to the spiral lifting lower rod 231. The extension length of the spiral lifting upper rod 232 is controlled by the spiral lifting wheel 233.

[0026] Unfold the two hinged movable steel support beams 25 of the dismantling frame 2 and align them with the two sides of the reserved opening 5 in the floor slab. Then, align the electric hoist 242 of the cantilever beam 241 of the lifting assembly 24 with the center position of the pump pipe to be dismantled. Use the spiral lifting wheel 233 of the lifting assembly 23 to adjust the spiral lifting rod 232 to the bottom of the floor slab 4, hold the floor slab 4 against it, fix the dismantling frame 2, and prevent the frame from sliding or displacing.

[0027] Secure the upper connector 12 of the first pump pipe section to be disassembled with a steel wire rope 244. Use the steel wire rope 243 of the electric hoist 242 to suspend the connector rope and lift it 0.3 meters. Then, use the U-shaped steel support 26 to clamp the upper connector 12 of the second pump pipe section below. Loosen the lower connector 13 of the first pump pipe section. Use the electric hoist 242 to lift and lower the first pump pipe section for pipe disassembly. Replace the steel wire rope 244 with the upper connector 12 of the next pump pipe section, and so on, until the entire disassembly section is completed.

[0028] Among them, a support steel plate 234 is fixedly installed at the upper end of the spiral lifting rod 232.

[0029] like Figure 1 As shown, the supporting steel plate 234 abuts against the lower end of the floor top plate 4 to securely position the dismantling frame 2, preventing lateral slippage during dismantling and ensuring its stability. The dismantling frame 2 is installed stably and reliably on the demolition floor, meeting the support requirements. The top supporting steel plate 234 is released using the spiral lifting wheel 233, the spiral lifting rod 232 is retracted, the two steel support beams 25 are folded, and the dismantling frame 2 is retracted. The dismantling frame 2 is then moved to the next pump pipe demolition floor using the moving wheels 29 and the push-pull handrail 210, until all pump pipes on each floor are completely demolished.

[0030] The lifting component 24 includes a cantilever beam 241, on which an electric hoist 242 is installed. The electric hoist 242 includes a wire rope 243, and one end of the wire rope 243 is provided with a wire binding rope 244.

[0031] The electric motor of the electric hoist 242 converts electrical energy into mechanical energy, driving the drum to rotate. The drum drives the wire rope 243, which in turn drives the wire binding rope 244. During the disassembly of the pump pipe, the pump pipe assembly 1 is connected via the wire binding rope 244, and the pump pipe assembly 1 is lifted or lowered under the drive of the electric hoist 242.

[0032] Among them, the cantilever beam 241 is welded and fixed on the support steel plate 234. An angle steel reinforcing plate is provided at the connection between the support steel plate 234 and the cantilever beam 241. During the disassembly of the pump pipe, the electric hoist 242 of the cantilever beam 241 needs to be aligned with the center position of the pump pipe to be disassembled.

[0033] Among them, the steel wire rope 244 is fixedly connected to the upper end joint 12 of the pump pipe assembly 1, and the pump pipe assembly 1 is lifted or lowered under the drive of the electric hoist 242.

[0034] Both the floor slab 3 and the floor slab 4 have reserved openings 5 ​​in the floor slab. The pump pipe assembly 1 passes through the reserved openings 5 ​​in the floor slab. Two steel support beams 25 are aligned with the two sides of the reserved openings 5 ​​in the floor slab. Figure 3 As shown, the two hinged movable steel support beams 25 of the dismantling frame 2 unfold and align with the two sides of the reserved opening 5 in the floor slab.

[0035] Among them, one end of each of the two steel support beams 25 is provided with a rubber pad 27, and the rubber pad 27 is fixedly connected to the steel support beam 25 by bolts 28. A push-pull handle 210 is fixedly installed on the dismantling frame connecting plate 22. The entire dismantling frame 2 is moved by the moving wheels 29 and the push-pull handle 210. The dismantling frame 2 is quick to install and dismantle and easy to move.

[0036] This utility model relates to a concrete pump pipe dismantling frame for high-rise buildings. In use, the diameter, wall thickness, and length of each section of the pump pipe to be dismantled are considered. The weight of each section is calculated, and a set of dismantling tools is designed based on this weight to dismantle the pump pipe assembly 1. Further, the folded and retractable dismantling frame 2 is transported to the floor where the pump pipe assembly 1 is to be dismantled using a personnel / freight elevator. Then, using the built-in casters 29, it is dragged to the pre-reserved opening 5 in the floor slab where the pump pipe needs to be dismantled. The dismantling frame 2 is installed on the pump pipe dismantling floor. Dismantling is performed on the pump pipes of floors 3-5 below this floor. The two hinged movable steel support beams 25 of the dismantling frame 2 are unfolded and aligned with both sides of the pre-reserved opening 5 in the floor slab. The electric hoist 242 of the cantilever beam 241 of the lifting assembly 24 is aligned with the center of the pump pipe to be dismantled. The spiral lifting wheel 233 of the lifting assembly 23 is used to adjust the spiral lifting rod 232 to the top of the floor. 4. At the bottom, hold the top of the floor 4 to fix the dismantling frame 2 and prevent it from sliding. Then, fix the upper end joint 12 of the first pump pipe to be dismantled with a steel wire rope 244. Use the steel wire rope 243 of the electric hoist 242 to suspend the joint rope and lift it 0.3 meters. Then, use the U-shaped steel support 26 to hold the upper end joint 12 of the second pump pipe below. Loosen the lower end joint 13 of the first pump pipe. Use the electric hoist 242 to lift and lower the first pump pipe for pipe dismantling. Change the steel wire rope 244 to the upper end joint 12 of the next pump pipe, and so on, until the entire dismantling section is completed. Use the spiral lifting wheel 233 to loosen the support of the top support steel plate 234, retract the spiral lifting rod 232, fold the two steel support beams 25, and retract the dismantling frame 2. Use the moving wheels 29 and the push-pull handrail 210 of the dismantling frame 2 to move to the next pump pipe dismantling floor until all pump pipes on each floor are dismantled.
