Description

Technical Field

[0001] The invention belongs to the technical field of locomotive maintenance, and in particular relates to a locomotive maintenance device. Background Art

[0002] Maintenance equipment is usually a comprehensive system, including various equipment used for maintenance, inspection, maintenance and recovery. These equipment can fully cover various systems and components of the maintenance, ensuring that the maintenance is fully and accurately inspected and repaired during the maintenance process. Since maintenance is faced with equipment containing thousands of parts and systems, such as engines, avionics systems, hydraulic systems, fuel systems, etc., each system has its specific functions and requirements. Therefore, various professional tools and equipment are needed during the maintenance process to ensure that these systems can operate normally. Due to the large number of maintenance tools, maintenance tool boxes are often needed to store the maintenance tools. Maintenance tool boxes are also part of maintenance equipment.

[0003] The existing locomotive maintenance device includes a locomotive maintenance tool box, and the maintenance tool box stores maintenance tools in a daily state. When the maintenance worker needs to use the maintenance tool, the maintenance worker takes the maintenance tool out of the maintenance tool box. However, when the maintenance worker performs maintenance on the locomotive, etc., the maintenance worker often needs to crawl into the interior of the locomotive structure for maintenance. In some locations inside the locomotive, the maintenance worker needs to move with the maintenance tools when entering the locomotive. However, some maintenance tools are heavy and inconvenient to carry. In this way, one worker needs to crawl into the locomotive and the other worker needs to pass the tools. This will result in two maintenance workers being required to complete the work, which is likely to cause a waste of resources or a maintenance worker crawling with the maintenance tools when there is only one maintenance worker. This will interfere with the crawling process of the maintenance worker.

[0004] Therefore we have proposed a kind of locomotive maintenance device, so as to solve the above-mentioned problem. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments.

[0022] In order to solve the problem that when maintenance workers crawl into the locomotive, it is inconvenient to carry maintenance tools and the locations where maintenance is required are in some narrow areas, how to transport maintenance tools to the maintenance workers' locations, such as Figure 1 - Fig.12 As shown: a locomotive maintenance device includes a maintenance box 1, a conveying component 2 is fixedly installed on the side wall of the maintenance box 1, a supporting component 3 is fixedly installed on the side wall of the maintenance box 1, and a controller 4 is fixedly installed on the top of the maintenance box 1. The maintenance box 1 is an intelligent control cabinet, which is a prior art and will not be described here. The controller 4 can control the opening and closing of the drawer and other structures of the maintenance box 1, and can control the working operation of the structure inside the entire locomotive maintenance device. A push handle 5 is fixedly installed on the side wall of the maintenance box 1, which can more conveniently push the entire maintenance box 1 to move.

[0023] The object conveying component 2 includes a first adjusting frame 201, which is fixedly installed on the side wall of the maintenance box 1. The inner wall of the first adjusting frame 201 is symmetrically penetrated by a first rotating shaft 202 that is rotatably connected. The two side walls of the first rotating shafts 202 are jointly fixedly installed with a first electric push rod 203. The movable end of the first electric push rod 203 is fixedly connected with a second adjusting frame 205. The inner wall of the second adjusting frame 205 is symmetrically penetrated by a second rotating shaft 206 that is rotatably connected. The side walls of the two second rotating shafts 206 are fixedly connected with a storage box 207, so that the vertical height of the storage box 207 can be controlled. When maintenance is required, the required maintenance tools can be taken out from the inside of the maintenance box 1 and placed in the storage box 207. Then, the maintenance tools can be moved to a height suitable for maintenance workers to take by moving the first electric push rod 203.

[0024] The support assembly 3 includes two groups of connecting plates 301, each connecting plate 301 is fixedly installed on the side wall of the maintenance box 1, and the side walls of two adjacent connecting plates 301 are rotatably connected to the rotating rod 302, so that the connecting plate 301 can support the rotating rod 302 so that the rotating rod 302 can rotate stably, and the side wall of the rotating rod 302 is fixedly connected to the supporting cylinder 303, so that when the rotating rod 302 rotates, it can drive the supporting cylinder 303 to rotate to control the inclination angle between the supporting cylinder 303 and the maintenance box 1, and the inner wall of the supporting cylinder 303 is fixedly installed with a second electric push rod 304, and the movable end of the second electric push rod 304 is fixedly connected to the supporting frame 305, so that the supporting frame 305 can be moved out of the supporting cylinder 303 by the second electric push rod 304.

[0025] A first motor 204 is fixedly installed on the side wall of the first adjustment frame 201, and the output end of the first motor 204 is fixedly connected to one end of one of the first rotating shafts 202, so that the inclination angle of the first electric push rod 203 can be adjusted, so that when the storage box 207 is moved, the storage box 207 can be moved in the direction according to the position required for maintenance by the maintenance staff, so as to better move the storage box 207 to a suitable place for the maintenance worker to take.

[0026] A second motor 208 is fixedly installed on the side wall of the second adjustment frame 205, and the output end of the second motor 208 is fixedly connected to one end of one of the second rotating shafts 206, so that the position and orientation of the storage box 207 can be adjusted. When the maintenance position required by the maintenance staff is relatively narrow, the storage box 207 is rotated to coincide with the position of the second adjustment frame 205, thereby shortening the space occupied by the storage box 207 in the horizontal position, so as to facilitate the storage box 207 to enter a relatively narrow area.

[0027] A first revolving door 209 is rotatably installed on the side wall of the storage box 207, and a second revolving door 210 is rotatably installed on the side wall of the storage box 207. The side walls of the first revolving door 209 and the second revolving door 210 are fixedly connected with handles 211. Therefore, in most cases, maintenance workers can take and place maintenance tools through the first revolving door 209. In some relatively narrow spaces, after the storage box 207 is rotated, maintenance tools can be taken and placed through the second revolving door 210, and the handle 211 allows maintenance workers to open the first revolving door 209 and the second revolving door 210 more conveniently.

[0028] The first revolving door 209 and the second revolving door 210 are both embedded with first magnetic blocks 212 in the side walls, and the storage box 207 is embedded with multiple second magnetic blocks 213 in the side walls. The first magnetic blocks 212 and the second magnetic blocks 213 correspond to each other one by one, and the first magnetic blocks 212 and the adjacent second magnetic blocks 213 attract each other. Therefore, under the action of the first magnetic blocks 212 and the second magnetic blocks 213, the first revolving door 209 and the second revolving door 210 are in contact with the side walls of the storage box 207 in a normal state, and sufficient external force is required to rotate the first revolving door 209 and the second revolving door 210. Therefore, in the process of moving the maintenance tools, the first revolving door 209 and the second revolving door 210 will not be opened due to the weight of the maintenance tools.

[0029] Preparation stage: When the maintenance worker needs to perform maintenance on the locomotive, he first observes the location to be maintained, takes out the required tools from the maintenance box 1, and puts them into the storage box 207 through the first rotating door 209, and then starts the first motor 204 according to the location to be maintained, rotates the first electric push rod 203 through the first rotating shaft 202, and then adjusts the direction of the first electric push rod 203. At this time, it is determined whether the space occupied by the storage box 207 in the horizontal direction needs to be adjusted according to whether the required maintenance location is narrow. If the required maintenance location is relatively wide, no adjustment is required. If the required maintenance location is relatively narrow, the second motor 208 is started, and the second motor 208 adjusts the space occupied by the storage box 207 in the horizontal position through the second rotating shaft 206, so that the storage box 207 overlaps with the second adjustment frame 205, and the second rotating door 210 faces the top, so that the storage box 207 can be moved to the vicinity of the maintenance worker through the gap in the narrow area during the subsequent movement.

[0030] Working stage: when the position adjustment of the storage box 207 is completed, the first electric push rod 203 is started again, so that the first electric push rod 203 drives the storage box 207 to move, and then moves the storage box 207 to a position convenient for the maintenance worker to take and put the maintenance tools. At this time, in most cases, the maintenance worker can take and put the maintenance tools through the first rotating door 209. In some narrow spaces, after the storage box 207 is rotated, the maintenance tools can be taken and put through the second rotating door 210, and the maintenance worker can use the handle 211 to more conveniently rotate the first rotating door 209 and the second rotating door 210 Since the first magnetic block 212 and the adjacent second magnetic block 213 attract each other under normal conditions, under the action of the first magnetic block 212 and the second magnetic block 213, the first revolving door 209 and the second revolving door 210 are in contact with the side wall of the storage box 207 under normal conditions, and sufficient external force is required to rotate the first revolving door 209 and the second revolving door 210. Therefore, in the process of moving the maintenance tool, the first revolving door 209 and the second revolving door 210 will not be opened due to the weight of the maintenance tool, and the maintenance tool will not fall from the storage box 207 during the entire process of moving the maintenance tool.

[0031] Through the entire preparation stage and the working stage, the process of moving the required maintenance tools is completed. The entire process only requires one maintenance worker to complete the entire maintenance work. When the maintenance worker needs to crawl into the interior of the maintenance component, he does not need to carry the maintenance tools himself, nor does he need other personnel to assist him, thereby enhancing the efficiency of the entire work and reducing the waste of human resources. When performing maintenance in some relatively narrow areas, the storage box 207 can still be moved to a position where it is convenient for the maintenance worker to take the maintenance tools, so that the entire device can be used in more scenarios, thereby better assisting the maintenance worker in performing maintenance work.

[0032] In order to solve the problem of how to keep the entire maintenance box 1 stable when the maintenance tools are heavy and the entire maintenance box 1 tends to tip over when the maintenance tools are transported to the maintenance worker's work location, as shown in FIG. Figure 8 - Fig.12 As shown: the inner wall of the support frame 305 is rotatably connected to an adjustment shaft 306, the side wall of the adjustment shaft 306 is fixedly connected to a short block 307, the inner wall of the support frame 305 is fixedly installed with a third motor 308, the output end of the third motor 308 is fixedly connected to one end of the adjustment shaft 306, and then the adjustment shaft 306 is rotated by controlling the third motor 308, so that the position of the short block 307 facing the ground can be adjusted.

[0033] A first support plate 309 is connected to the top of the short block 307, and an insertion rod 310 is fixedly connected to the top of the first support plate 309. When it is necessary to repair the high-speed railway, etc., since the high-speed railway and other devices are located on the track, and the ground of the track is not very flat and there are many stones, if the high-speed railway is repaired in the rain or after the rain, the ground soil will be muddy after absorbing water, and if an object is directly in contact with the ground, it is easy to cause the object to slip, resulting in poor support effect. At this time, if the maintenance tool needs to be moved to the maintenance worker, first start the third motor 308 to rotate the insertion rod 310 to a position in contact with the ground, and then move the support frame 305 through the second electric push rod 304 to insert the insertion rod 310 into the ground, so that the entire maintenance box 1 can be better supported to prevent the maintenance box 1 from tipping over.

[0034] A support column 311 is fixedly connected to the bottom of the short block 307, and a second support plate 312 is rotatably connected to the bottom of the support column 311. When the maintenance box 1 needs to be supported on some relatively flat ground, the second electric push rod 304 is started to extend the second support plate 312 out of the support tube 303. When the second support plate 312 contacts the ground, since the second support plate 312 is rotatably connected to the support column 311, no matter what angle the support column 311 is at, the second support plate 312 can still fully contact the ground.

[0035] A short box 314 is fixedly connected to the side wall of the support tube 303 , and a slider 315 is slidably connected to the inner wall of the short box 314 . The short box 314 can limit the movement trajectory of the slider 315 so that the slider 315 can only move along the inner wall of the short box 314 .

[0036] A third electric push rod 313 is fixedly installed on the side wall of the maintenance box 1, and the output end of the third electric push rod 313 is rotatably connected to the side wall of the slider 315, so that the third electric push rod 313 can push the entire support tube 303 to rotate by pushing the slider 315, and then adjust the inclination angle of the support tube 303, so that the side wall of the support tube 303 can form a triangular support angle with the side wall of the maintenance box 1 and the ground. The triangle has stability, and can better maintain the stability of the maintenance box 1, so that when the maintenance tools inside the storage box 207 are moved, the maintenance box 1 will not have a tendency to tip over due to local overweight.

[0037] When adjusting the position of the storage box 207 in the preparation stage, if the maintenance tools placed in the storage box 207 are heavy, or the first electric push rod 203 is extended a long distance, in order to prevent the maintenance box 1 from tilting due to the heavy local gravity, it is necessary to first start the third electric push rod 313 before starting the first electric push rod 203 and other structures. The third electric push rod 313 moves by pushing the slider 315, thereby pushing the entire support tube 303 to move, and then adjusting the inclination angle of the support tube 303, so that the side wall of the support tube 303 can form a support angle similar to a triangle with the side wall of the maintenance box 1 and the ground. It is well known that the triangle has stability, and the support tube 303 can better maintain the stability of the maintenance box 1.

[0038] Then, the second electric push rod 304 is started to move the support frame 305 out of the support tube 303. At the same time, the third motor 308 is started according to the ground conditions of the area where the maintenance box 1 is located. When the ground is relatively flat, the second support plate 312 is adjusted out of the support frame 305. When the second support plate 312 is in contact with the ground, since the second support plate 312 is rotatably connected to the support column 311, no matter what inclination angle the support column 311 is at, the second support plate 312 can still be fully in contact with the ground, thereby supporting the side wall of the maintenance box 1. When the ground is muddy or the ground is land or has many stones, the insertion rod 310 is adjusted out of the support frame 305. When the insertion rod 310 is in contact with the ground, the insertion rod 310 is inserted into the land, thereby strengthening the fixed relationship between the insertion rod 310 and the land, so that the entire support tube 303 can better support the maintenance box 1. When the support is completed, the position and orientation angle of the storage box 207 are adjusted.

[0039] Furthermore, by setting up the support assembly 3 and its internal structure, the inclination angle of the support tube 303 can be adjusted, and the positional relationship between the insertion rod 310 and the second support plate 312 can be adjusted. Then, if the ground is relatively flat, the second support plate 312 is used to contact the ground, and then the support assembly 3 supports the maintenance box 1. When repairing the high-speed railway, etc., if the ground of the track is not very flat and there are many stones, or the high-speed railway is repaired in the rain or after the rain, and the ground soil is muddy after absorbing water, the insertion rod 310 is used to be inserted into the soil, and the second support plate 312 is not used for support to prevent the second support plate 312 from slipping with the soil, thereby resulting in poor support effect.

[0040] The first motor 204 , the second motor 208 , and the third motor 308 all have a brake function, and therefore when the first motor 204 , the second motor 208 , and the third motor 308 are not started respectively, the first electric push rod 203 , the storage box 207 , and the short block 307 will not rotate.
