Conical hollow pier internal diameter adjustment lifting platform

Abstract

This utility model provides an adjustable lifting platform for a conical hollow pier, comprising a conical well and a crane. A retractable platform is installed inside the conical well, including a central platform and two side platforms. Multiple support frames are mounted on the side platforms. The central platform and the two side platforms are slidably connected. The crane is connected to the central platform via multiple steel cables, and the support frames are connected to the conical well. When the retractable platform is raised or lowered, the central platform slides relative to the side platforms, thus adapting to conical wells with different cross-sectional widths. This avoids the cumbersome, time-consuming, and labor-intensive process of erecting scaffolding, as well as the repeated disassembly and reassembly of the work platform; and the need to add or remove work boards on both sides of the work platform according to different width requirements. This significantly saves time on scaffolding erection and reduces the time spent on repeated disassembly and reassembly of the work platform, improving construction efficiency.

Description

Technical Field

[0001] This utility model relates to the field of hollow pier construction, and in particular to an internal diameter adjustment lifting platform for conical hollow piers. Background Technology

[0002] The existing hollow piers have an inclined inner wall structure. Construction needs to be carried out inside the hollow piers with inclined inner walls, and a construction platform needs to be built inside the hollow piers for workers to carry out the work.

[0003] The existing construction method involves first erecting scaffolding inside the pier, and then using the scaffolding as a support to build work platforms for personnel. Due to the inclined inner wall of the hollow pier, the internal width varies at different heights, necessitating the construction of work platforms of varying widths to accommodate the corresponding inner wall space. This method of scaffolding erection is complex, requiring the assembly and fixing of each individual member, consuming significant manpower and time, and resulting in a long overall construction preparation period. Adjusting the construction height necessitates repeated disassembly and reassembly of the work platforms, further reducing construction efficiency. To match the width requirements at different heights, work boards need to be added or removed from both sides of the work platforms, increasing the complexity of the construction process and raising both construction and time costs. Utility Model Content

[0004] This utility model provides an internal diameter adjustment lifting platform for conical hollow piers, which solves the problems of the need to erect scaffolding for the inclined inner wall of hollow piers, the complicated scaffolding erection process, the time-consuming and labor-intensive overall construction process, the need to repeatedly disassemble and reassemble the work platform when the construction height needs to be adjusted, the low operation efficiency, and the need to add or remove work boards on both sides of the work platform to match the width requirements of different heights, which increases the complexity of the construction process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a conical hollow pier internal diameter adjustment lifting platform, including a conical well and a crane. A retractable platform is provided inside the conical well. The retractable platform includes a middle platform and two side platforms. Multiple support side frames are provided on the side platforms. The middle platform and the two side platforms are slidably connected. The crane is connected to the middle platform through multiple steel cables. The support side frames are connected to the conical well.

[0006] In the preferred embodiment, the conical well has a rectangular cross-section, and the four sides of the inner wall of the conical well are inclined surfaces, with multiple reserved holes on the inclined surfaces of the conical well.

[0007] In the preferred embodiment, the intermediate platform includes a top plate, and multiple sliding beams are provided on both sides of the bottom of the top plate. One end of each sliding beam is provided with a limiting plate and a lifting lug, and the lifting lug is connected to the crane via a steel cable.

[0008] In the preferred embodiment, the side platform includes a flat plate with multiple mounting slots and multiple connecting beams, and the supporting side frame rests against the mounting slots.

[0009] In a preferred embodiment, the supporting side frame includes a horizontal frame, one end of which is provided with a vertical frame, and the bottom of the horizontal frame is provided with multiple supporting beams, which are connected to the connecting beams.

[0010] In the preferred embodiment, the crossbeam is provided with a cross groove, the bottom of the crossbeam abuts against the top of the mounting groove, and the sliding beam slides against the cross groove.

[0011] In the preferred embodiment, the top of the crossbeam is provided with a top roller, the bottom of the crossbeam is provided with multiple bottom rollers, and the slide beam is located between the top roller and the bottom roller.

[0012] In the preferred embodiment, a plurality of side rollers are provided on one side of the vertical frame, and the side rollers abut against the inner wall of the conical well.

[0013] In the preferred embodiment, a positioning bolt is provided at one end of the vertical frame, and the positioning bolt is connected to the conical well through a reserved hole.

[0014] The beneficial effects of this utility model are as follows: When construction is required inside a conical well, a crane is driven to lift the entire device to the bottom of the inner wall of the conical well. Workers at the bottom of the conical well pull apart the side platforms on both sides so that they abut against the inner wall of the well. Then, workers manually work on the retractable platform, using positioning bolts to connect the entire device to the conical well. When construction at this height is completed and the entire device needs to be moved upwards, multiple positioning bolts are removed manually. Workers stand on the middle platform, and the crane lifts the middle platform, causing the entire device to move upwards. Under the thrust of the inclined surface of the conical well, the side platforms on both sides move closer to the middle platform relative to the middle platform, allowing the overall structure to adapt to the width required at different heights. When the desired height is reached, the crane stops working, and the supporting side frames are reconnected to the conical well using the positioning bolts. This operation is repeated from top to bottom until construction is complete.

[0015] When the retractable platform is raised or lowered, the middle platform slides relative to the side platforms, thus accommodating conical wells of varying cross-sectional widths. This avoids the cumbersome, time-consuming, and labor-intensive process of erecting scaffolding, as well as the need for repeated disassembly and reassembly of the work platform. It also eliminates the need to add or remove working boards on both sides of the platform to meet different height and width requirements. This significantly saves time on scaffolding erection and reduces the time spent on repeated disassembly and reassembly of the work platform, thereby improving construction efficiency.

[0017] Example 1: like Figure 1-7 In the conical hollow pier, the diameter adjustment lifting platform includes a conical well 1 and a crane. The conical well 1 is equipped with a retractable platform 2, which includes a middle platform 4 and two side platforms 3. Multiple support side frames 5 are provided on the side platforms 3. The middle platform 4 and the two side platforms 3 are slidably connected. The crane is connected to the middle platform 4 through multiple steel cables 7, and the support side frames 5 are connected to the conical well 1. With this structure, when construction is required inside the conical well 1, the crane is driven to lift the entire assembly to the bottom of the inner wall of the conical well 1. Workers at the bottom of the conical well 1 pull apart the two side platforms 3, so that the two side platforms 3 abut against the inner wall of the conical well 1. Then, workers work on the retractable platform 2, connecting the entire assembly to the conical well 1 using positioning bolts 6. When construction at this height is completed and the entire assembly needs to be moved upwards, multiple positioning bolts 6 are removed manually. Workers stand on the middle platform 4, and the crane lifts the middle platform 4, moving the entire assembly upwards. Under the thrust of the inclined surface 101 of the conical well 1, the two side platforms 3 move closer to the middle platform 4 relative to the middle platform 4, allowing the overall structure to adapt to the width required at different heights. When the desired height is reached, the crane stops working, and the supporting side frame 5 is reconnected to the conical well 1 using the positioning bolts 6. This operation is repeated from top to bottom until construction is complete.

[0018] When the retractable platform 2 is raised or lowered, the middle platform 4 slides relative to the side platforms 3, thus accommodating conical wells 1 with different cross-sectional widths. This avoids the cumbersome, time-consuming, and labor-intensive process of erecting scaffolding, as well as the need for repeated disassembly and reassembly of the work platform. It also avoids the need to add or remove work boards on both sides of the work platform according to different height and width requirements. This significantly saves time on scaffolding erection and reduces the time spent on repeated disassembly and reassembly of the work platform, thereby improving construction efficiency.

[0019] In the preferred embodiment, the conical well 1 has a rectangular cross-section, and the four sides of the inner wall of the conical well 1 are inclined surfaces 101. Multiple pre-drilled holes 102 are provided on the inclined surfaces 101 of the conical well 1. With this structure, the positioning bolts 6 pass through the pre-drilled holes 102 and the crossbeam 501 of the supporting side frame 5, so that the supporting side frame 5 is connected to the conical well 1, thereby connecting the overall structure to the conical well 1.

[0020] In the preferred embodiment, the intermediate platform 4 includes a top plate 401, with multiple sliding beams 402 on both sides of the bottom of the top plate 401. One end of each sliding beam 402 is equipped with a limiting plate 403 and a lifting lug 404, which is connected to the crane via a steel cable 7. With this structure, when the overall structural height remains fixed, the crane stops working, and the entire structure is connected to the conical well 1. When the overall structural height needs to be changed, the crane is driven to raise or lower the intermediate platform 4, allowing the side platforms 3 to slide relative to the intermediate platform 4.

[0021] In a preferred embodiment, the side platform 3 includes a flat plate 301 with multiple mounting slots 302 and multiple connecting beams 303. The supporting side frame 5 abuts against the mounting slots 302. With this structure, the supporting side frame 5 is installed in the mounting slots 302, and the connecting beams 303 are connected to the supporting beams 503 of the supporting side frame 5.

[0022] In a preferred embodiment, the supporting side frame 5 includes a horizontal frame 501, with a vertical frame 502 at one end of the horizontal frame 501. Multiple supporting beams 503 are located at the bottom of the horizontal frame 501, and the supporting beams 503 are connected to the connecting beams 303. With this structure, In a preferred embodiment, the crossbeam 501 is provided with a transverse groove 5011, the bottom of the crossbeam 501 abuts against the top of the mounting groove 302, and the sliding beam 402 slides against the transverse groove 5011. With this structure, the sliding beam 402 slides against the transverse groove 5011, so that when the intermediate platform 4 is raised or lowered, the intermediate platform 4 slides relative to the supporting side frame 5, so that the intermediate platform 4 slides relative to the side platforms 3, and so that the two side platforms 3 open and close relative to the intermediate platform 4.

[0023] In a preferred embodiment, the top of the crossbeam 501 is provided with a top roller 504, and the bottom of the crossbeam 501 is provided with multiple bottom rollers 505. The slide beam 402 is located between the top roller 504 and the bottom rollers 505. With this structure, the top roller 504 and the bottom rollers 505 serve to limit the slide beam 402 and at the same time reduce the friction between them.

[0024] In a preferred embodiment, a plurality of side rollers 506 are provided on one side of the vertical frame 502, and the side rollers 506 abut against the inner wall of the conical well 1. With this structure, the side rollers 506 reduce the friction between the conical well 1 and the supporting side frame 5.

[0025] In the preferred embodiment, one end of the vertical frame 502 is provided with a positioning bolt 6, which is connected to the conical well 1 through a reserved hole 102.
