Description

Technical Field

[0001] The present invention relates to the technical field of working platforms, and particularly to a quickly disassemblable working platform for installing pier crane fences. Background Art

[0002] In the field of bridge construction and maintenance, the installation operation of pier crane fences is an important link to ensure the safety of bridge structures and construction personnel. Traditionally, for the construction of pier crane fences, the hoisting operation is mostly carried out by directly installing a hanging basket on a crane.

[0003] However, when facing high pier construction, this method exposes significant safety hazards and operational inconveniences. When the pier height is relatively large, forming a high pier construction environment, the risk factor of traditional hanging basket hoisting operation increases significantly. The stability of the hanging basket in the air is difficult to guarantee, and it is vulnerable to external factors such as wind force and mechanical vibration, resulting in serious safety risks for construction personnel, such as falling from a height and being hit by objects. In addition, the positioning and fixing between the hanging basket and the pier are difficult, and it is difficult to achieve precise adjustment of the installation position, affecting the construction quality and efficiency.

[0004] To address the above problems, there is an urgent need in the market for a safer, more efficient, and more convenient working platform for installing pier crane fences. The present invention proposes a quickly disassemblable working platform for installing pier crane fences, which realizes the quick installation and disassembly of platform components through innovative structural design and connection methods, improves construction efficiency, and ensures safety and reliability during the construction process. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the prior art and propose a quickly disassemblable working platform for installing pier crane fences.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quickly disassemblable working platform for installing pier crane fences includes platform components installed on the pier main body. Two platform components are used in cooperation. The pier main body includes a pier shaft and a cushion stone, and the cushion stone is fixed on the top of the pier shaft. The platform component includes a platform main body and a suspension mechanism. The suspension mechanism includes a second I-beam and rollers movably connected to the bottom of the second I-beam. A lifting lug is welded on the side wall of the second I-beam, and the second I-beam, the lifting lug, and the platform main body are connected by a connecting piece. A telescopic member is installed on the side wall of the second I-beam, and a clamping assembly for clamping the cushion stone is installed at the end of the telescopic member.

[0008] As a further solution of the present invention: The connecting piece includes a second rolled threaded steel and a third nut. The lifting lug and the platform panel, as well as the second I-beam and the platform panel, are fixed by the second rolled threaded steel and the third nut.

[0009] As a further solution of the present invention: The clamping assembly includes a chute and a slideway. The chute is opened at the top of the slideway, and a clamping plate is movably connected to the inner wall of the chute. Anti-slip pads are bonded to the inner walls of the two clamping plates.

[0010] As a further solution of the present invention: Side plates are welded to the top of the slideway. A bidirectional threaded rod is movably connected between the two side plates. The bidirectional threaded rod is threadedly connected to the clamping plate, and a joint is fixed to one end of the bidirectional threaded rod.

[0011] As a further solution of the present invention: The telescopic member includes a connecting plate and a hydraulic cylinder. The connecting plate is fixed to the two side walls of the I-beam, and the hydraulic cylinder is fixed to the side wall of the connecting plate. The output end of the hydraulic cylinder is fixedly connected to the slideway.

[0012] As a further solution of the present invention: The platform main body includes a guardrail and a platform panel. The guardrail is welded to the top of the platform panel. A cushion block is welded to the bottom of the platform panel. A protective door is movably connected to the outer wall of the guardrail.

[0013] As a further solution of the present invention: A plug plate is welded to the side wall of one of the platform panels, and a slot adapted to the plug plate is opened on the side wall of the other platform panel. The slot and the plug plate are fixed by a second nut and a locking bolt.

[0014] As a further solution of the present invention: The platform panel is fixed to the I-beam 1 at the bottom through a mounting member. The mounting member includes a rolled threaded steel 1 and a nut 1. The rolled threaded steel 1 is inserted into the platform panel and the I-beam 1.

[0015] As a further solution of the present invention: The rolled threaded steel 1 and the platform panel, as well as the I-beam 1 and the rolled threaded steel 1, are locked by the nut 1.

[0016] As a further solution of the present invention: A U-shaped hole is opened in the middle of the platform panel. The U-shaped hole is adapted to the pier body. Modular double-spliced channel steel back ribs are welded around the U-shaped hole at the top of the platform panel.

[0017] Compared with the prior art, the present invention provides a quickly detachable operation platform for the installation of pier crane fences, which has the following beneficial effects:

[0018] 1. The overall rapid lifting and installation of the platform components are realized by a crane, and the rapid positioning and fixing are realized by means of the telescopic member and the clamping assembly, significantly shortening the installation time; during disassembly, only the relevant locking components need to be loosened to easily remove the platform components, greatly improving the construction efficiency.

[0019] 2. Utilizing the telescopic characteristics of the hydraulic cylinder, the working platform can accurately adjust the position of the platform main body in the transverse direction to ensure the accurate relative position with the pier main body. This fine-tuning function enhances the adaptability of the platform to pier main bodies of different sizes and improves the versatility of the platform.

[0020] 3. The clamping assembly realizes the firm clamping of the cushion stone through the close cooperation of the bidirectional threaded rod and the clamping plate, thereby ensuring the stability of the platform main body relative to the pier main body. At the same time, rolled threaded steel and nuts are used for fixation, further enhancing the connection strength between the platform components and significantly improving the stability of the entire working platform.

[0021] 4. The guardrail welded on the platform main body provides effective safety protection for construction workers, reducing the safety risks during the construction process. The guard door rotatably connected to the outer wall of the guardrail facilitates the construction workers to enter the platform through equipment such as elevators and ensures the safety of the construction workers on the platform.

[0022] 5. By fixing the first I-beam at the bottom of the platform panel and using the first rolled threaded steel and the first nut for stable locking, the working platform further enhances the overall stability. This design helps to disperse the load on the platform, reduce the shaking and deformation during the construction process, and thus improve the safety and efficiency of the construction.

[0023] The parts not involved in this device are the same as or can be implemented using the prior art. The structure of the present invention is simple and the operation is convenient. Description of the Drawings

Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1

[0033] A quickly detachable and installable operation platform for installing a pier hanging fence, as Figures 1 to 6 shown, includes a platform component installed on the pier main body, and two platform components are used in cooperation. The pier main body includes a pier body 1 and a bearing pad 4. The bearing pad 4 is fixed on the top of the pier body 1. The platform component includes a platform main body and a suspension mechanism. The suspension mechanism includes an I-beam two 3 and a roller 28 rotatably connected to the bottom of the I-beam two 3. A lifting lug 25 is welded on the side wall of the I-beam two 3, and the I-beam two 3, the lifting lug 25 and the platform main body are connected by a connecting member. A telescopic member is installed on the side wall of the I-beam two 3, and a clamping component for clamping the bearing pad 4 is installed at the end of the telescopic member;

[0034] When it is necessary to assemble between the platform component and the pier main body, connect the hook of the crane with the lifting lug 25, and lift the whole platform component through the crane and the lifting lug 25. Before that, connect and fix the I-beam two 3 and the platform main body on the ground in advance through a connecting member. When the I-beam two 3 moves above the pier body 1, it will slowly descend until the bottom of the roller 28 fits between the top of the pier body 1. Then use the clamping component to clamp and fix both sides of the bearing pad 4. The bearing pad 4 is used to support the bridge. After the clamping component and the bearing pad 4 are clamped and fixed, by controlling the telescopic movement of the output end of the hydraulic cylinder 21, the roller 28 at the bottom of the I-beam two 3 can roll along the top of the pier body 1 to finely adjust the position of the platform main body in the transverse direction, and at the same time, the clamping component ensures the stability of the platform main body relative to the pier main body.

[0035] The platform body includes a guardrail 7 and a platform panel 8. The guardrail 7 is welded to the top of the platform panel 8. A U-shaped hole is formed in the middle of the platform panel 8, which is adapted to the pier body 1. A cushion block 16 is welded to the bottom of the platform panel 8, and modular double-channel steel back ribs 14 are welded around the platform panel 8 near the U-shaped hole at the top. A protective door 9 is rotatably connected to the outer wall of the guardrail 7;

[0036] The platform panel 8 is used for construction workers to stand on. The guardrail 7 plays a protective role. After the protective door 9 is opened, it is convenient for construction workers to enter through lifting equipment such as elevators. The cushion block 16 can support the platform panel 8 when the platform panel 8 is on the ground.

[0037] The connecting member includes a rolled ribbed steel bar two 26 and a nut three 27. The fixing between the lifting lug 25 and the platform panel 8 and between the I-beam two 3 and the platform panel 8 is carried out through the rolled ribbed steel bar two 26 and the nut three 27;

[0038] When fixing between the I-beam two 3 and the platform panel 8, insert the rolled ribbed steel bar two 26 into the mounting holes on the I-beam two 3, the platform panel 8 and the rolled ribbed steel bar two 26, and use the nut three 27 to lock the lifting lug 25. In this embodiment, it is preferably locked with double nuts three 27.

[0039] The clamping assembly includes a chute 19 and a slideway 24. The chute 19 is opened at the top of the slideway 24. A clamping plate 13 is slidably connected to the inner wall of the chute 19. Anti-slip pads 17 are bonded to the inner walls of the two clamping plates 13. Side plates 18 are welded to the top of the slideway 24. A bidirectional threaded rod 23 is rotatably connected between the two side plates 18, and the bidirectional threaded rod 23 is threadedly connected to the clamping plate 13. One end of the bidirectional threaded rod 23 is fixed with a joint 22;

[0040] When it is necessary to clamp and fix the cushion stone 4, connect the joint 22 to a motor or an electric wrench, so as to drive the bidirectional threaded rod 23 to rotate. During the rotation of the bidirectional threaded rod 23, the two clamping plates 13 move relative to each other under the guiding action of the chute 19 until the anti-slip pads 17 on the two clamping plates 13 clamp the side wall of the cushion stone 4.

[0041] The telescopic member includes a connecting plate 20 and a hydraulic cylinder 21. The connecting plate 20 is fixed to the side wall of the I-beam two 3, and the hydraulic cylinder 21 is fixed to the side wall of the connecting plate 20. The output end of the hydraulic cylinder 21 is fixedly connected to the slideway 24;

[0042] After the clamping assembly clamps and fixes the cushion stone 4, control the telescopic movement of the hydraulic cylinder 21 to adjust the position of the platform panel 8 relative to the side surface of the pier body 1.

[0043] A plug plate 11 is welded to the side wall of one of the platform panels 8, and a slot 10 adapted to the plug plate 11 is opened on the side wall of the other platform panel 8, and the slot 10 and the plug plate 11 are fixed by a nut 15 and a locking bolt 12;

[0044] Since the lateral position of the platform panel 8 can be adjusted by the telescopic member, after the two platform assemblies are hoisted, the telescopic member is used to adjust the relative movement between the two platform panels 8 until the slot 10 and the plug plate 11 are inserted into each other. After the slot 10 and the plug plate 11 are inserted into each other, the slot 10 and the plug plate 11 are locked by the nut 15 and the locking bolt 12.

[0045] Working principle: The I-beam 23 in the platform assembly and the platform body including the guardrail 7 and the platform panel 8 are pre-connected and fixed on the ground by means of rolled threaded steel 26 and nuts 3 27. Specifically, the rolled threaded steel 26 is inserted into the mounting holes on the I-beam 23 and the platform panel 8, and locked by means of double nuts 3 27 to ensure a firm connection between the I-beam 23 and the platform panel 8. The hook of the crane is connected to the lifting lug 25 welded on the side wall of the I-beam 23, and the platform assembly is lifted as a whole by means of the crane and moved to the pier body. 1, slowly lower the platform assembly until the roller 28 connected to the bottom of the I-beam 23 is in contact with the top of the pier body 1, start the motor or electric wrench and connect it to the joint 22 at one end of the two-way threaded rod 23, drive the two-way threaded rod 23 to rotate, and during the rotation of the two-way threaded rod 23, drive the two sets of clamping plates 13 to move relative to each other under the guidance of the slide groove 19, until the anti-skid pads 17 on the two clamping plates 13 clamp and fix the side wall of the cushion stone 4, and the extension and contraction of the hydraulic cylinder 21 can drive the roller 28 at the bottom of the I-beam 23 to move along the top of the pier body 1 The platform body 8 is rolled in a horizontal direction, thereby fine-tuning the horizontal position of the platform body to ensure that the relative position between the platform body and the pier body 1 is accurate. Since the horizontal position of the platform panel 8 can be adjusted by the telescopic hydraulic cylinder 21, after the two platform components are hoisted, the telescopic component is used to adjust the relative movement between the two platform panels 8 until the plug plate 11 of the side wall of one platform panel 8 is inserted into the slot 10 of the side wall of the other platform panel 8. The nut 2 15 and the locking bolt 12 are used to lock the slot 10 and the plug plate 11 to ensure a stable connection between the two platform components. Construction personnel can open the protective door 9 on the outer wall of the guardrail 7 and use lifting equipment such as elevators to enter the platform body. The platform panel 8 is used for construction personnel to stand, and the guardrail 7 plays a protective role to ensure the safety of construction personnel. When it is necessary to dismantle the platform, first loosen the nut 2 15 and the locking bolt 12 to separate the two platform components, and then control the hydraulic cylinder 21 to contract, drive the clamping plate 13 to loosen the clamping of the pad stone 4, and finally use the crane to lift and remove the platform component as a whole to complete the disassembly process.

To further ensure the stability of the working platform, as Figures 1 to 6 shown, the following supplements are made in this embodiment on the basis of Embodiment 1: A first I-beam 2 is fixed to the bottom of the platform panel 8 through a mounting member. The mounting member includes a first rolled threaded steel 5 and a first nut 6. The first rolled threaded steel 5 is inserted between the platform panel 8 and the first I-beam 2. The first rolled threaded steel 5 and the platform panel 8, as well as the first I-beam 2 and the first rolled threaded steel 5, are locked by the first nut 6;

[0048] After the assembly and fixation between two platform components are completed, the first I-beam 2 is placed above the pier body 1 between two cushion stones 4. The first I-beam 2 and the platform panel 8 are fixed through the first rolled threaded steel 5 and the first nut 6 to further ensure the stability of the entire working platform.
