Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane maintenance technology, specifically to a crane maintenance platform. Background Technology
[0002] The modular integrated building factory is equipped with a large number and variety of bridge cranes and gantry cranes. During peak production periods, the production, decoration, and transportation of precast concrete components are concentrated and busy, leading to frequent use of lifting machinery. Sudden malfunctions can occur both day and night, necessitating a corresponding increase in the frequency of regular maintenance and inspection. The factory's high ceilings necessitate different maintenance areas, facilities, equipment, and tools for different types of lifting machinery. In particular, the unique suspension of the hoist trolley on single-girder bridge cranes makes maintenance and regular inspection difficult without specialized aerial work platforms. Currently, most crane maintenance and repair in the factory relies on the crane's own structure, which compromises worker safety during full crane inspections. Many complex maintenance and repair procedures, especially for single-girder bridge cranes, require external aerial work platforms. However, if equipment or components are installed on the ground, these platforms cannot access the site, resulting in low maintenance efficiency, impacting production rhythm, and increasing equipment safety risks due to the low frequency of equipment inspections. Furthermore, the personal safety of maintenance and repair personnel is not adequately guaranteed.
[0003] Therefore, there is an urgent need to propose a crane maintenance platform. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a crane maintenance platform.
[0005] The objective of this utility model can be achieved through the following technical solutions: A crane maintenance platform, comprising: Main maintenance platform, auxiliary maintenance platform, and support structures; The main maintenance platform and the auxiliary maintenance platform are hinged together by high-strength hinges, allowing the auxiliary maintenance platform to be folded or unfolded relative to the main maintenance platform. The support mechanism includes a first steel wire rope and a first support channel steel. The first support channel steel is parallel to the upper surface of the main maintenance platform. The first support channel steel is welded to the steel beams or walls of the plant. The two ends of the first steel wire rope are respectively installed on the auxiliary maintenance platform and the steel beams of the plant. The first steel wire rope is diagonally pulled above the main maintenance platform.
[0006] As a further embodiment of this utility model: at least two sets of the first wire rope and the first support channel steel are provided, the two sets of the first wire rope are parallel to each other, and the two sets of the first support channel steel are parallel to each other.
[0007] As a further embodiment of this utility model: guardrails are fixedly installed on the sides of both the main maintenance platform and the auxiliary maintenance platform, and the guardrails are assembled by welding round tubes.
[0008] As a further embodiment of this utility model: a detachable fence is provided between the guardrails on both sides of the auxiliary maintenance platform, and the detachable fence is located on the side of the auxiliary maintenance platform away from the main maintenance platform.
[0009] As a further embodiment of this utility model: the detachable fence includes a second steel wire rope, which has multiple parallel wire ropes.
[0010] As a further embodiment of this utility model, both ends of the first and second wire ropes are provided with installation components.
[0011] As a further embodiment of this utility model: the installation component includes a wire rope clamp disposed at the end of the wire rope, the wire rope clamp folds and fixes the end of the wire rope to form a heart-shaped loop, and a detachable shackle is provided on the heart-shaped loop; A first lifting lug is fixedly connected to the side of the auxiliary maintenance platform away from the main maintenance platform. A shackle at one end of the first wire rope passes through the first lifting lug to fix the first wire rope to the auxiliary maintenance platform. A second lifting lug is welded to the steel beam of the plant. A shackle at the other end of the first wire rope passes through the second lifting lug to fix the first wire rope to the steel beam of the plant.
[0012] As a further embodiment of this utility model: a third lifting lug is fixedly connected to the guardrail of the auxiliary maintenance platform, and the shackles at both ends of the second wire rope pass through the third lifting lug on both sides of the guardrail to detachably fix the second wire rope to the auxiliary maintenance platform.
[0013] As a further embodiment of this utility model, the upper surfaces of both the main maintenance platform and the auxiliary maintenance platform are covered with patterned steel plates.
[0014] As a further embodiment of this utility model: at least two sets of parallel second support channel steels are welded to the bottom of the main maintenance platform, and the second support channel steels are welded to the steel beams or walls of the factory building.
[0015] The beneficial effects of this utility model are as follows: This utility model uses a hinged connection structure composed of high-strength hinges between the main maintenance platform and the auxiliary maintenance platform, enabling the auxiliary maintenance platform to be foldable or unfoldable. This achieves flexible and convenient storage of the platform's working area, effectively overcoming the shortcomings of fixed platforms, such as large space occupation and inability to avoid equipment in the factory. At the same time, the composite support mechanism, composed of a first supporting channel steel welded to the steel beams or walls of the factory and a first steel wire rope inclined above the main maintenance platform, provides reliable rigid foundation support and spatial inclined stabilization for the platform. The first supporting channel steel directly transmits the main load to the factory's load-bearing structure, while the first steel wire rope effectively offsets the torque generated by the auxiliary platform and its load by bearing the tension, significantly enhancing the overall structure's anti-overturning resistance and rigidity, and suppressing swaying during operation. The synergistic cooperation of the above structures ultimately enables this maintenance platform to combine deployment flexibility and operational stability. It can be deployed in a "nomadic" manner and quickly switch states in different locations in the plant according to maintenance needs, effectively solving the technical dilemma that the aerial equipment cannot reach the work point due to ground obstacles, and providing safe and reliable working conditions for close-range and high-efficiency maintenance of key components of lifting machinery.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] See Figures 1-2 This utility model discloses a crane maintenance platform, comprising: a main maintenance platform 1, a secondary maintenance platform 2, and a support mechanism 3; the main maintenance platform 1 and the secondary maintenance platform 2 are hinged together by a high-strength hinge 4, allowing the secondary maintenance platform 2 to be folded or unfolded relative to the main maintenance platform 1; the support mechanism 3 includes a first wire rope 31 and a first support channel steel 32, the first support channel steel 32 being parallel to the upper surface of the main maintenance platform 1, the first support channel steel 32 being welded to the steel beams or walls of the factory building, and the two ends of the first wire rope 31 being respectively installed on the secondary maintenance platform 2 and the steel beams of the factory building, with the first wire rope 31 being diagonally stretched above the main maintenance platform 1.
[0021] Specifically, this utility model utilizes a hinged connection structure with high-strength hinges between the main maintenance platform 1 and the auxiliary maintenance platform 2, enabling the auxiliary maintenance platform 2 to be foldable or unfoldable. This achieves flexible and convenient storage of the platform's working area, effectively overcoming the shortcomings of fixed platforms that occupy a large space and cannot avoid equipment within the factory building. Simultaneously, the composite support mechanism 3, consisting of a first supporting channel steel 32 welded to the steel beams or walls of the factory building and a first steel wire rope 31 diagonally stretched above the main maintenance platform 1, provides reliable rigid foundation support and spatial diagonal stabilization for the platform. The first supporting channel steel 32 directly transmits the main load to the factory building's load-bearing structure, while the first steel wire rope 31 effectively counteracts the torque generated by the auxiliary platform and its load by bearing the tension, significantly enhancing the overall structure's resistance to overturning and rigidity, and suppressing swaying during operation. The synergistic cooperation of the above structures ultimately enables this maintenance platform to combine deployment flexibility and operational stability. It can be deployed in a "nomadic" manner and quickly switch states in different locations in the plant according to maintenance needs, effectively solving the technical dilemma that the aerial equipment cannot reach the work point due to ground obstacles, and providing safe and reliable working conditions for close-range and high-efficiency maintenance of key components of lifting machinery.
[0022] See Figures 1-2 Optionally, at least two sets of the first wire rope 31 and the first support channel steel 32 are provided, with the two sets of the first wire rope 31 being parallel to each other and the two sets of the first support channel steel 32 being parallel to each other.
[0023] In this embodiment, by setting up multiple parallel supports, the platform load is evenly distributed to the factory structure, which greatly enhances the overall stability and load-bearing capacity of the platform and effectively prevents the platform from twisting or tilting under load.
[0024] See Figures 1-3 Optionally, guardrails 5 are fixedly installed on the sides of both the main maintenance platform 1 and the auxiliary maintenance platform 2. The guardrails 5 are assembled by welding round tubes.
[0025] In this embodiment, the circular tube guardrail 5 constitutes a rigid protective boundary around the platform. Its welded structure is sturdy and durable, which can effectively prevent workers from falling from heights. In addition, special hook points can be set on the guardrail 5 to facilitate workers to hang safety belts.
[0026] See Figures 1-3 Optionally, a detachable fence 6 is provided between the guardrails 5 on both sides of the auxiliary maintenance platform 2, and the detachable fence 6 is located on the side of the auxiliary maintenance platform 2 away from the main maintenance platform 1.
[0027] In this embodiment, when the auxiliary maintenance platform 2 is deployed and in use, the detachable fence 6 is used to close the outer opening of the auxiliary platform, forming a complete working protection area. When components such as electric hoists of lifting machinery need to be brought close to the platform for maintenance, the detachable fence 6 can be quickly disassembled, providing the necessary operating space and flexibility.
[0028] See Figure 3 Optionally, the detachable fence 6 includes a second wire rope 61, which has multiple parallel wire ropes.
[0029] In this embodiment, multiple parallel second steel wire ropes 61 are used to form a fence, which ensures sufficient protective strength while achieving lightweight fence and does not easily obstruct the view, making it convenient for workers to observe the operating environment.
[0030] See Figures 1-3 Optionally, both ends of the first wire rope 31 and the second wire rope 61 are provided with mounting components 7.
[0031] In this embodiment, the standardized installation component 7 unifies the connection method of the wire rope, ensures the reliability and consistency of all wire rope connection points, and simplifies the installation and maintenance process.
[0032] See Figures 1-4Optionally, the installation component 7 includes a wire rope clamp 71 disposed at the end of the wire rope. The wire rope clamp 71 folds and fixes the end of the wire rope to form a heart-shaped loop 72. A detachable shackle 73 is threaded through the heart-shaped loop 72. A first lifting lug 311 is fixedly connected to the side of the auxiliary maintenance platform 2 away from the main maintenance platform 1. The shackle 73 at one end of the first wire rope 31 passes through the first lifting lug 311 to fix the first wire rope 31 to the auxiliary maintenance platform 2. A second lifting lug 312 is welded to the steel beam of the plant. The shackle 73 at the other end of the first wire rope 31 passes through the second lifting lug 312 to fix the first wire rope 31 to the steel beam of the plant.
[0033] In this embodiment, the combination of wire rope clamp 71, heart ring 72 and shackle 73 enables the rapid and reliable connection and disassembly of the first wire rope 31 with the maintenance platform and factory structure. The shackle 73 connection method is easy to adjust and install, while the wire rope clamp 71 can ensure that the rope end is firmly fixed.
[0034] See Figures 1-4 Optionally, a third lifting lug 611 is fixedly connected to the guardrail 5 of the auxiliary maintenance platform 2, and the shackles 73 at both ends of the second wire rope 61 pass through the third lifting lug 611 on both sides of the guardrail 5 to detachably fix the second wire rope 61 to the auxiliary maintenance platform 2.
[0035] In this embodiment, when components such as electric hoists of lifting machinery need to be inspected near the platform, workers can remove the corresponding height and number of second wire ropes 61 from the third lifting lug 611 as needed. The electric hoist can be as close as possible to the workers, making it convenient to inspect the trolley mechanism, lifting motor, brake bolts, internal coupling, two-section shaft, gearbox, angle iron pulley, etc. of the electric hoist. This is quick and efficient, and the safety factor is also greatly improved.
[0036] See Figure 2 Optionally, both the main maintenance platform 1 and the auxiliary maintenance platform 2 are covered with patterned steel plates 8.
[0037] In this embodiment, the patterned steel plate 8 provides a non-slip working surface with a high coefficient of friction, effectively preventing workers from falling and improving the safety performance of this maintenance platform.
[0038] See Figures 1-2 Optionally, at least two sets of parallel second support channel steels 9 are welded to the bottom of the main maintenance platform 1. The second support channel steels 9 are welded to the steel beams or walls of the plant.
[0039] In this embodiment, the second support channel steel 9 provides the main bottom load-bearing support for the platform, working in conjunction with the first support channel steel 32 and the first wire rope 31 to more evenly distribute the platform and its load to the factory's load-bearing structure. This design further enhances the platform's rigidity, prevents deformation, and ensures the platform's stability and safety under long-term and heavy-load use.
