Description

Technical Field

[0001] This utility model relates to the field of locomotive maintenance technology, and in particular to a climbing device for a locomotive maintenance platform and a locomotive maintenance platform. Background Technology

[0002] Locomotive maintenance platforms are primarily used for routine inspections and maintenance of locomotives, ensuring they are in good operating condition before leaving the depot or turning back. Locomotive maintenance platforms are typically multi-layered (e.g., three layers) to facilitate comprehensive inspections. When inspecting equipment such as the pantograph on the locomotive roof, workers usually need to climb onto the roof. However, the locomotive roof is often curved to reduce drag during operation, making it difficult for workers to stand. Therefore, a climbing device is installed on the top layer of the locomotive maintenance platform to assist workers in reaching the roof for inspection work.

[0003] In existing technologies, a foldable access ramp is typically installed on the top layer of the locomotive maintenance platform. When access work is required, workers flip and open the ramp, placing it on the locomotive roof to provide a platform for inspection. After the inspection is completed, workers remove the ramp and fold it back up. However, using this type of access device for inspection requires workers to repeatedly flip and open or fold the ramp. The ramp's weight increases the workload and is time-consuming. Furthermore, repeated flipping can cause wear and tear on the ramp's rotating connection structure, increasing the failure rate of the access device. Utility Model Content

[0004] The purpose of this utility model is to provide a climbing device for a locomotive maintenance platform and a locomotive maintenance platform, which can reduce the labor intensity of workers, save time and effort, and reduce the failure rate of the climbing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Optionally, the climbing device for the locomotive preparation platform further includes a limiting plug. The upper surface of the guide has multiple through holes 1, and the lower surface of the guide has multiple through holes 2. The multiple through holes 1 and the multiple through holes 2 are vertically aligned. The through holes 1 communicate with the through holes 2 through the sliding groove. The limiting plug can be inserted into the through holes 1 and the through holes 2 to limit the sliding mating parts in the horizontal direction.

[0009] Optionally, the climbing device for the locomotive preparation platform further includes a first stop and a second stop, wherein the first stop and the second stop are respectively disposed at both ends of the guide along the extension direction of the guide to stop the sliding mating member in the horizontal direction.

[0010] Optionally, the climbing device for the locomotive preparation platform further includes a drive mechanism. The housing of the drive mechanism is disposed on the top platform, and the output end of the drive mechanism is connected to the support frame for driving the support frame to move horizontally.

[0033] Example 1

[0034] This embodiment provides a climbing device for a locomotive maintenance platform, such as... Figures 1 to 3 As shown, the climbing device is installed on the top platform 100 of the locomotive maintenance platform to assist the staff in their inspection work. This can reduce the labor intensity of the staff, save time and effort, and reduce the failure rate of the climbing device.

[0035] like Figures 1 to 3As shown, the climbing device for the locomotive maintenance platform is installed on the top platform 100 of the locomotive maintenance platform, which is located on one side of the locomotive along its width. The climbing device for the locomotive maintenance platform includes a support frame 1 and a support ramp 2. The support frame 1 is horizontally adjustable and installed on the top platform 100. The support frame 1 has an operational state where it is erected on the locomotive roof and a retracted state where it is stacked on the top platform 100. The support ramp 2 is installed on the upper surface of the support frame 1.

[0036] When it is necessary to climb to the top for maintenance work, simply adjust the position of the load-bearing frame 1 horizontally so that the load-bearing frame 1 is close to the locomotive on the side of the top platform 100 and is placed on the roof of the locomotive. At this time, one end of the load-bearing frame 1 is connected to the locomotive, and the other end is installed on the top platform 100. That is, the load-bearing frame 1 connects the top platform 100 and the locomotive. At this time, the load-bearing frame 1 is in operation, and the load-bearing ramp 2 is set on the load-bearing frame 1. The load-bearing ramp 2 provides a working platform for the workers, who can stand on the load-bearing ramp 2 to inspect the equipment on the roof of the locomotive.

[0037] After the inspection is completed, the workers remove the supporting ramp 2 and readjust the position of the supporting frame 1 horizontally to separate it from the locomotive, then stack it on the top platform 100. By making the supporting frame 1 horizontally adjustable, during inspection, the supporting ramp 2 can be connected to the locomotive and the top platform 100 simply by adjusting its position horizontally. Workers do not need to lift or flip the supporting frame 1 and the supporting ramp, reducing labor intensity, saving time and effort, and minimizing damage to the climbing device caused by repeated wear and tear on the connecting structure, thus reducing the failure rate.

[0038] Optionally, such as Figures 1 to 3 As shown, the climbing device for the locomotive maintenance platform also includes two guide members 11 and multiple sliding fitting members 12. The two guide members 11 are installed at intervals on the top platform 100. Each guide member 11 has a sliding groove extending horizontally. Multiple sliding fitting members 12 are located on both sides of the supporting frame 1, and each sliding fitting member 12 can be slidably engaged within the sliding groove. When climbing for maintenance work is required, the operator simply pushes the supporting frame 1 and the supporting ramp 2 horizontally, causing the sliding fitting members 12 to slide along the sliding grooves of the guide members 11 until the end of the supporting frame 1 facing away from the top platform 100 is aligned with the locomotive roof. Pushing then stops, thus adjusting the position of the supporting frame 1. The structure is simple and easy to operate. By setting the guide members 11 and sliding fitting members 12 to work together, a guiding effect can be provided for the movement of the supporting frame 1, thereby improving the accuracy of its movement direction and ensuring the connection effect between the supporting frame 1 and the locomotive.

[0039] In this embodiment, four sliding mating parts 12 are provided. In other embodiments, other numbers of sliding mating parts 12 may be provided as needed, and this is not limited here.

[0040] For example, the guide member 11 includes a C-shaped hanging rail channel steel, and the sliding mating member 12 includes a roller.

[0041] Optionally, such as Figures 1 to 3 As shown, the climbing device for the locomotive maintenance platform also includes a limiting plug 13. The upper surface of the guide member 11 has multiple through holes 112, and the lower surface of the guide member 11 has multiple through holes 2. The multiple through holes 112 and multiple through holes 2 are vertically aligned, and the through holes 112 communicate with the through holes 2 through sliding grooves. The limiting plug 13 can be inserted into the through holes 112 and through holes 2 to limit the sliding fitting 12 in the horizontal direction.

[0042] During inspection, the supporting frame 1 and the supporting ramp 2 are pushed, and the sliding mating part 12 slides along the sliding groove of the guide part 11. The sliding stops when the supporting frame 1 overlaps with the locomotive roof. The limiting plug 13 is then inserted into the two through holes 112 and 2 closest to the sliding mating part 12, thus horizontally limiting the sliding mating part 12 and fixing the supporting frame 1. This prevents the supporting frame 1 and the supporting ramp 2 from shaking due to the sliding displacement of the sliding mating part 12, ensuring the safety of the personnel. After the inspection is completed, the position of the supporting frame 1 is reversed, separating it from the locomotive and stacking it on the top platform 100. The limiting plug 13 is again inserted into the two through holes 112 and 2 closest to the sliding mating part 12, thus fixing the supporting frame 1 and preventing the supporting frame 1 from interfering with the locomotive's departure due to the sliding displacement of the sliding mating part 12.

[0043] In this embodiment, two through holes 112 are provided, and correspondingly two through holes 2 are provided. In other embodiments, more than two through holes 112 and through holes 2 may be provided as needed, and this is not limited here.

[0044] Optionally, such as Figures 1 to 3 As shown, the climbing device for the locomotive maintenance platform also includes a first stop 3 and a second stop 4. The first stop 3 and the second stop 4 are respectively disposed at both ends of the guide member 11 along the extending direction of the guide member 11. When the sliding mating member 12 slides along the sliding groove, the first stop 3 and the second stop 4 can stop the sliding mating member 12 in the horizontal direction, thereby preventing the sliding mating member 12 from disengaging from the sliding groove of the guide member 11 and ensuring the normal use of the climbing device.

[0045] Optionally, at least one of the first stop 3 and the second stop 4 is detachably connected to the guide 11. When a component of the climbing device is damaged, such as the sliding fit 12, the load-bearing frame 1, or the load-bearing ramp 2, the first stop 3 or the second stop 4 can be disassembled, and the load-bearing frame 1 can be pushed, causing the sliding fit 12 to drive the load-bearing frame 1 to slide along the sliding groove and disengage from the sliding groove, thereby facilitating the repair of the damaged component.

[0046] In this embodiment, the first stop 3 is disposed on the side of the guide 11 away from the locomotive, and the side of the guide 11 away from the locomotive is provided with a connecting part 111. The plug bolt passes through the first stop 3 and the connecting part 111 and is threadedly connected to the fastening nut. The second stop 4 is fixed to the side of the guide 11 close to the locomotive by welding.

[0047] In other embodiments, the first stop 3 and the second stop 4 may be configured to be detachably connected to the guide 11, depending on actual needs; this is not limited here.

[0048] Optionally, the climbing structure for the locomotive maintenance platform also includes a drive mechanism. The housing of the drive mechanism is mounted on the top platform 100, and the output end of the drive mechanism is connected to the support frame 1 for driving the support frame 1 to move horizontally. When it is necessary to push the support frame 1, simply activate the drive mechanism to extend or retract its output end horizontally, thereby driving the support frame 1 to move horizontally and adjusting the position of the support frame 1. The structure is simple and easy to operate.

[0049] For example, the drive mechanism includes a hydraulic telescopic cylinder.

[0050] Optionally, such as Figures 1 to 3 As shown, the climbing structure for the locomotive maintenance platform also includes a protective structure 5. The protective structure 5 includes at least one protective frame 51, which is mounted on the load-bearing ramp 2. When climbing to the top for inspection work, workers need to stand on the load-bearing ramp 2 to perform the work. By setting up the protective frame 51, the workers can be surrounded to prevent them from falling and improve the safety of the inspection work.

[0051] In this embodiment, two protective frames 51 are provided. The two protective frames 51 are located at both ends of the load-bearing ramp 2 along the length of the locomotive. They can not only protect workers from falling during operation, but also prevent workers from being hindered from climbing to the top.

[0052] Optionally, such as Figures 1 to 3As shown, the enclosure structure 5 also includes a handrail 52, which is located on the side of the enclosure frame 51 facing away from the locomotive. When it is necessary to move the load-bearing frame 1, the operator can push the enclosure frame 51 by holding the handrail 52. By providing the handrail 52, a base for the operator to apply force is provided, which is conducive to pushing the enclosure frame 51. The structure is simple and easy to operate.

[0053] Optionally, the enclosure structure 5 also includes a protective sleeve, which is fitted onto the handrail 52. By providing the protective sleeve, safety can be improved, and workers can hold the protective sleeve to push the load-bearing frame 1, avoiding bumps or scratches and improving the comfort of use.

[0054] For example, the protective sleeve includes a rubber protective sleeve.

[0055] Example 2

[0056] This embodiment provides a locomotive maintenance platform, including a top platform 100 and a climbing device as described above. The climbing device is installed on the top platform 100. When it is necessary to climb the platform for inspection work, the position of the supporting frame 1 of the climbing device is adjusted horizontally so that it is erected on the roof of the locomotive, thereby connecting the top platform 100 and the locomotive, providing a standing platform for the staff to carry out the inspection work and ensuring the smooth progress of the inspection work.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
