Description
Technical Field
[0001] This utility model relates to the field of vehicle maintenance, and more specifically, to a special safety platform device for vehicle maintenance. Background Technology
[0002] Overhead crane is a general term for cranes, gantry cranes, overhead cranes, and other types of cranes. There are two basic types of overhead crane drive methods: one is centralized drive, which uses a single electric motor to drive a long transmission shaft to drive the two drive wheels on both sides; the other is separate drive, which uses a separate electric motor to drive each of the two drive wheels on both sides. Medium and small bridge cranes often use a drive method that combines the brake, reducer, and electric motor into one unit. For large lifting capacity ordinary bridge cranes, universal couplings are often used in the drive device for ease of installation and adjustment.
[0003] When disassembling and installing large equipment such as couplings, reducers, and thrusters for maintenance work on the overhead crane trolley, the confined space and suspended position make it extremely inconvenient for personnel to carry out the work. A slight lapse in attention can lead to objects slipping or even personnel falling, resulting in unsafe situations. Furthermore, the increased difficulty of maintenance increases the labor intensity of workers and reduces maintenance efficiency, while also posing a risk of falling objects from height. Therefore, a special safety platform device for overhead crane maintenance is proposed to solve the above problems. Utility Model Content
[0004] To overcome the risks of objects slipping and personnel falling due to the confined and suspended working space of existing crane maintenance operations, this utility model provides a special safety platform device for crane maintenance, including a crane platform. A linear slide rail is fixedly installed on the top of the crane platform. A lifting trolley is slidably installed inside the linear slide rail. A positioning component is attached to the outside of the lifting trolley. A telescopic component is fixedly connected to the bottom of the positioning component. An outer shell component is fitted around the telescopic component. A protective component is fixedly installed on the top of the outer shell component.
[0005] A sliding component is fixedly installed at the bottom of the housing assembly, and the sliding component is slidably installed inside the linear slide rail.
[0006] Preferably, the outer shell assembly includes a cover, the inside of which is provided with a slot, the telescopic component is movably installed inside the slot, a protective component is fixedly installed on the top of the cover, a sliding component is fixedly installed on the bottom of the cover, and sliding grooves are provided on both sides of the inner wall of the cover.
[0007] Preferably, the telescopic assembly includes a movable telescopic plate, and limit strips are fixedly installed on both the left and right side walls of the movable telescopic plate. The two limit strips are slidably installed inside the two slide grooves respectively. An anti-derailment block is fixedly installed at one end of the movable telescopic plate, and a positioning component is fixedly installed on the top of the movable telescopic plate at the end away from the anti-derailment block.
[0008] Preferably, the positioning component includes a mounting base, which is fixedly mounted on the top of the movable telescopic plate. A threaded lifting rod is threadedly mounted on the top of the mounting base, and a connecting bearing is rotatably connected to the bottom of the threaded lifting rod. An overlapping buckle is fixedly connected to the outer wall of the connecting bearing.
[0009] Preferably, the lap buckle is L-shaped.
[0010] Preferably, the protective component includes a guardrail, which is fixedly installed on the top of the enclosure, and an adsorption magnet plate is fixedly installed on the outer wall of the guardrail.
[0011] Preferably, the sliding assembly includes a base frame, which is fixedly installed on the bottom of the housing, and a slider is fixedly installed on the bottom of the base frame, the slider being slidably installed inside the linear guide rail.
[0012] Preferably, a protective fence is fixedly installed on one side of the vehicle platform.
[0013] Beneficial effects:
[0014] The beneficial effects of adopting the technical solution of this utility model are as follows:
[0015] (1) The cover can be installed on the linear slide rail by the sliding component. At the same time, the cover has a slot to accommodate the movable telescopic plate. During maintenance, the movable telescopic plate can be extended to form a larger maintenance platform with the cover. Meanwhile, the positioning component can be connected to the lifting trolley to improve stability and prevent slippage. This makes it convenient for staff to maintain, disassemble and install large equipment on the lifting trolley from the side, avoiding the problem that maintenance can only be carried out from the side of the crane platform, and improving maintenance efficiency and convenience.
[0016] (2) Since the movable telescopic plate can be stored inside the cover, it occupies less space. After maintenance, it can be stored on the vehicle platform. In order to provide safety, an adsorption magnet plate is also installed on the guardrail, which can increase the adsorption stability with the protective fence and ensure that there is no displacement or risk of falling.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:
[0027] like Figures 1 to 3 As shown, a special safety platform device for crane maintenance includes a crane platform 1. A linear slide rail 2 is fixedly installed on the top of the crane platform 1. A lifting trolley 3 is slidably installed inside the linear slide rail 2. A positioning component 4 is attached to the outside of the lifting trolley 3. A telescopic component 5 is fixedly connected to the bottom of the positioning component 4. A shell assembly 6 is fitted over the telescopic component 5. A protective component 7 is fixedly installed on the top of the shell assembly 6. A sliding component 9 is fixedly installed on the bottom of the shell assembly 6. The sliding component 9 is slidably installed inside the linear slide rail 2. The shell assembly 6 includes a cover 61. A slot 60 is opened inside the cover 61. The telescopic component 5 is movably installed inside the slot 60. A [missing information - likely a component name] is fixedly installed on the top of the cover 61. The protective component 7 and the bottom of the cover 61 are fixedly installed with a sliding component 9. The inner walls of the cover 61 are provided with sliding grooves on both sides. The telescopic component 5 includes a movable telescopic plate 50. The left and right side walls of the movable telescopic plate 50 are fixedly installed with limit strips 51. The two limit strips 51 are slidably installed in the two sliding grooves respectively. One end of the movable telescopic plate 50 is fixedly installed with an anti-derailment block 52. The top of the movable telescopic plate 50 away from the anti-derailment block 52 is fixedly installed with a positioning component 4. The movable telescopic plate 50 can be scaled up and down inside the slot 60 to cooperate with the cover 61 to form a larger platform area or reduce the occupation for easy storage. The anti-derailment block 52 can prevent the movable telescopic plate 50 from overextending and separating from the cover 61.
[0028] In addition, the positioning component 4 includes a mounting base 40, which is fixedly installed on the top of the movable telescopic plate 50. A threaded lifting rod 41 is threadedly installed on the top of the mounting base 40, and a connecting bearing 42 is rotatably connected to the bottom of the threaded lifting rod 41. An overlapping buckle 43 is fixedly connected to the outer wall of the connecting bearing 42. The overlapping buckle 43 is L-shaped. The positioning component 4 is used to connect with the lifting trolley part 3 to prevent the sliding component 9 from driving the outer shell component 6 to move during maintenance. When overlapping, the movable telescopic plate 50 is first extended close to the lifting trolley part 3 according to the required area. At the same time, the threaded lifting rod 41 is rotated to descend so that the overlapping buckle 43 overlaps with the lifting trolley part 3. The overlapping buckle 43 is an inverted L-shaped buckle, which can easily overlap with the lifting trolley part 3 to ensure the overall stability during maintenance operations.
[0029] like Figures 4 to 6As shown, the protective component 7 includes a guardrail 70, which is fixedly installed on the top of the housing 61. An adsorption magnet plate 71 is fixedly installed on the outer wall of the guardrail 70. The guardrail 70 can provide single-sided protection during maintenance operations. Combined with the protection of the other two sides by the overhead crane platform 1, and the other side facing the lifting trolley 3, the staff are protected by safe distances and protection measures on all four sides, avoiding the risk of falling.
[0030] It should be noted that a protective fence 8 is fixedly installed on one side of the overhead platform 1. The sliding component 9 includes a base frame 90, which is fixedly installed on the bottom of the cover 61. A slider 91 is fixedly installed on the bottom of the base frame 90. The slider 91 is slidably installed inside the linear guide rail 2. After maintenance, the sliding component 9 and its connecting structure can be directly separated from the linear guide rail 2 and placed directly on the overhead platform 1 for easy storage for future use. The guardrail 70 is also equipped with an adsorption magnet plate 71 to increase the adsorption force with the protective fence 8, making it easy to store and preventing the equipment from shifting.
[0031] Working principle: The slider 91 is adapted to be installed in the linear slide rail 2 to achieve quick loading and unloading. During maintenance, since the lifting trolley 3 can only be maintained from the side while standing on the overhead platform 1, it is very inconvenient. The cover 61 can be installed on the linear slide rail 2 near the lifting trolley 3 through the base frame 90 and the slider 91. The area available for standing is increased by extending the movable telescopic plate 50. At the same time, the threaded lifting rod 41 is rotated to push the overlapping buckle 43 to overlap with the lifting trolley 3. The lifting trolley 3 bears the force of the movable telescopic plate 50 and plays a role in stabilizing the connection, preventing the slider 91 from sliding when it is being protected. After maintenance, the movable telescopic plate 50 is stored in the empty slot 60, and the slider 91 is separated from the linear slide rail 2. Finally, it is stored on the overhead platform 1 for the next use.
[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
