Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction platforms, specifically a liftable bridge construction anti-fall platform. Background Technology

[0002] Bridge construction platforms are key equipment in bridge construction and maintenance. They can be divided into various types according to construction scenarios and functional requirements. Their core features include structural adaptability, automated operation, and safety assurance.

[0003] Traditional bridge construction platforms generally use fixed single-layer guardrails as edge protection devices. This structure can only provide basic blocking function and lacks the ability to buffer and support people falling suddenly, resulting in relatively low safety. Utility Model Content

[0004] The purpose of this utility model is to provide a liftable bridge construction fall protection platform, which solves the problem that traditional bridge construction platforms generally use fixed single-layer guardrails as edge protection devices. This structure can only provide basic blocking function and lacks the ability to buffer and support personnel in case of sudden falls, thus resulting in relatively low safety.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a liftable bridge construction anti-fall platform, including a base, a lifting mechanism installed on the upper surface of the base, a plurality of self-locking moving wheels installed on the lower surface of the base, a construction platform fixedly installed on the lifting end of the lifting mechanism, a guardrail fixedly installed on the upper surface of the construction platform, a plurality of anti-slip stripes opened on the upper surface of the construction platform, an anti-fall mechanism fixedly installed on one side of the guardrail, and the anti-fall end of the anti-fall mechanism is located on one side of the construction platform.

[0006] Furthermore, the fall protection mechanism includes a fixing plate, which is fixedly installed on one side of the guardrail. Connecting plates are fixedly installed on the outer surfaces of both ends of the fixing plate. Threaded grooves are opened on the upper surface of each connecting plate, and connecting shells are rotatably connected to the outer surface of each connecting plate.

[0007] Furthermore, each of the upper surfaces of the connecting shells is fixedly installed with a limiting shell, and each limiting shell is threaded with a connecting bolt, which is connected through the internal threads of the limiting shell and the threaded groove.

[0008] Furthermore, an installation frame is fixedly installed on one side of each of the two connecting shells.

[0009] Furthermore, several hanging rings are fixedly installed on the lower surface of the mounting frame.

[0010] Furthermore, each of the hanging rings has a hook attached inside.

[0011] Furthermore, a safety net is fixedly installed at one end of several of the hooks.

[0012] The present invention has the following beneficial effects: (1) The present invention rotates the mounting frame on the connecting plate through the connecting shell. When the mounting frame is rotated to a parallel state, the threaded groove on the limiting shell and the threaded groove are aligned. Then the mounting frame is threaded into the limiting shell and the threaded groove to complete the fixing of the mounting frame. This allows the anti-fall net installed by the mounting frame through the hanging ring and hook to be spread out on one side of the construction platform, thereby effectively capturing sudden fall accidents and reducing the casualty rate of high-altitude operations.

[0013] (2) By unscrewing the connecting bolts from the inside of the threaded groove and the limiting shell, the mounting frame can rotate around the connecting plate through the connecting shell. By rotating the mounting frame to a vertical position, the large area occupied by the anti-fall mechanism when the device is not in use can be avoided.

[0014] (3) The present invention can prevent workers from slipping when standing on the construction platform by opening multiple anti-slip stripes on the surface of the construction platform, thereby improving the safety of construction.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figures 1-4 As shown, this utility model is a liftable bridge construction anti-fall platform, including a base 1, a lifting mechanism 2 installed on the upper surface of the base 1, a plurality of self-locking moving wheels 3 installed on the lower surface of the base 1, a construction platform 4 fixedly installed at the lifting end of the lifting mechanism 2, a guardrail 5 fixedly installed on the upper surface of the construction platform 4, a plurality of anti-slip stripes 6 opened on the upper surface of the construction platform 4, and an anti-fall mechanism 7 fixedly installed on one side of the guardrail 5, with the anti-fall end of the anti-fall mechanism 7 located on one side of the construction platform 4.

[0024] The base 1 is the basic load-bearing and moving unit of the entire equipment. It is a sturdy frame structure welded from high-strength rectangular steel pipes or H-beams to ensure that it has sufficient rigidity and anti-overturning capacity during lifting and operation.

[0025] The self-locking casters 3 are several omnidirectional or directional casters installed on the lower surface of the base. Their core feature is that they have a self-locking function.

[0026] The lifting mechanism 2 adopts a double scissor hydraulic lifting system, which has the advantages of smooth lifting, strong load-bearing capacity, good synchronization and low working noise.

[0027] Construction platform 4 provides working space for construction workers; guardrail 5 is a standard safety enclosure structure to prevent people from falling or slipping out.

[0028] The fall arrestor 7 is the key feature that distinguishes this platform from ordinary lifting platforms. Its fall arrestor end is located on one side of the construction platform, forming an active fall arrest barrier.

[0029] The device is moved by the self-locking moving wheel 3. After reaching the designated position, the self-locking moving wheel 3 is locked. Then, the worker stands on the construction platform 4 and the construction platform 4 is driven to rise and fall vertically by the lifting mechanism 2 on the base 1 to carry out subsequent construction operations. The multiple anti-slip stripes 6 on the surface of the construction platform 4 can prevent the worker from slipping when standing on the construction platform 4, thus improving the safety of construction.

[0030] The fall arrestor 7 includes a fixing plate 701, which is fixedly installed on one side of the guardrail 5. Connecting plates 702 are fixedly installed on the outer surfaces of both ends of the fixing plate 701. Threaded grooves 703 are opened on the upper surface of each connecting plate 702. Connecting shells 704 are rotatably connected to the outer surfaces of each connecting plate 702. Limiting shells 705 are fixedly installed on the upper surface of each connecting shell 704. Connecting bolts 706 are threadedly connected inside each limiting shell 705. The connecting bolts 706 are connected through the internal threads of the limiting shell 705 and the threaded grooves 703. An installation frame 707 is fixedly installed on one side of each of the two connecting shells 704.

[0031] When the device is not in use, by unscrewing the connecting bolt 706 from the inside of the threaded groove 703 and the limiting shell 705, the mounting frame 707 can be rotated around the connecting plate 702 via the connecting shell 704. Rotating the mounting frame 707 to a vertical position can avoid the situation where the fall protection mechanism 7 occupies a large area when the device is not in use.

[0032] Several hanging rings 708 are fixedly installed on the lower surface of the mounting frame 707; hooks 709 are attached to the inside of each hanging ring 708; and a fall protection net 710 is fixedly installed at one end of each hook 709.

[0033] By rotating the mounting frame 707 on the connecting plate 702 via the connecting shell 704, when the mounting frame 707 is rotated to a parallel state, the threaded grooves 705 and 703 on the limiting shell 705 are aligned. Then, the mounting frame 707 is threaded into the limiting shell 705 and the threaded grooves 703 to fix the mounting frame 707. This allows the fall protection net 710, which is installed on the mounting frame 707 via the hanging ring 708 and hook 709, to unfold on one side of the construction platform 4, thereby effectively capturing sudden fall accidents and reducing the injury rate of high-altitude operations.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
