Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically a maintenance platform for transportation environmental protection engineering. Background Technology

[0002] Transportation engineering is an engineering field that studies the layout and construction of railway, highway, waterway and air transport infrastructure, the engineering of vehicle operation, traffic information engineering and control, and the operation and management of transportation. Railway transportation, highway transportation, waterway transportation and air transportation are the main modes of transportation in modern society, and maintenance platforms are used in transportation engineering.

[0003] Existing maintenance platforms for transportation engineering are inconvenient to adjust in height and move during use, causing great inconvenience to users and failing to meet actual usage needs.

[0004] For example, the maintenance platform for transportation engineering disclosed in Chinese Patent CN216428963U solves the problem that existing maintenance platforms for transportation engineering are inconvenient to adjust in height and move during use, causing great inconvenience to users and failing to meet actual usage needs. This is achieved through the coordinated use of a base plate, adjustment box, platform, support column, connecting rod, limit plate, slot, insertion rod, tension spring, shell, moving block, trapezoidal groove, support rod, motor, screw, threaded sleeve, first roller, support rod, second roller, cross plate, trapezoidal block, support leg, pulley, spring and support.

[0005] However, the maintenance platform lacks a structure to secure the traffic equipment to be inspected, making it difficult to ensure the stability of the traffic equipment on the maintenance platform during maintenance.

[0006] Therefore, we urgently need to provide a maintenance platform with a fixed structure for environmental protection engineering in transportation. Utility Model Content

[0007] The purpose of this utility model is to provide a maintenance platform for environmental protection engineering in transportation, so as to solve the problem mentioned in the background art that the maintenance platform does not have a structure to fix the traffic equipment to be repaired, thus making it difficult to ensure the fixation of the traffic equipment on the maintenance platform during maintenance.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a maintenance platform for environmental protection engineering in transportation, comprising a base plate and casters, wherein the casters are fixedly connected to the four lower corners of the base plate, a working platform is provided at the upper end of the base plate, and a maintenance mechanism is connected to the upper end of the base plate, wherein the maintenance mechanism comprises a fixing unit and an adjusting unit, the fixing unit is provided at the upper end of the working platform, and the adjusting unit is provided between the base plate and the working platform.

[0009] The fixing unit includes an inclined plate, a slider, a motor, a fixing block, a bearing, a first threaded rod, a second threaded rod, an adjusting plate, and a connecting plate. The inclined plate is connected to the upper end of the working platform. The slider is fixedly connected to the middle position of the front and rear sides of the inclined plate. The motor is symmetrically fixedly connected to the middle position of the front and rear sides of the working platform. The fixing block is fixedly connected to the left and right ends of the front and rear sides of the working platform. The bearing is fixedly connected to the inner side of the fixing block. The first threaded rod is fixedly connected to the inner side of the bearing. The second threaded rod is fixedly connected to the end of the first threaded rod away from the bearing. The adjusting plate is connected to the outer ends of the first and second threaded rods. The connecting plate is fixedly connected to the upper end of the adjusting plate.

[0010] A further improvement is that grooves are formed at the four corners of the upper interior of the working platform, and sliding grooves are formed at the front and rear ends of the grooves inside the working platform. The front and rear sides of the lower end of the inclined plate are slidably connected to the inner side of the groove, and the outer side of the slider is slidably connected to the inner side of the sliding groove. Thus, when the inclined plate slides inside the groove, the sliders at its front and rear ends slide inside the sliding groove, thereby limiting the movement of the inclined plate.

[0011] A further improvement is that the lower inner end of the adjusting plate has a threaded hole, and the outer sides of the first and second threaded rods are threadedly connected to the inner side of the threaded hole. The output shaft of the motor is fixedly connected to the end of the second threaded rod away from the first threaded rod, and the side of the connecting plate away from the adjusting plate is fixedly connected to the outer side of the inclined plate. The first and second threaded rods are symmetrical. Therefore, when the motor is started and its output shaft rotates, causing the second and first threaded rods to rotate together, the two outer adjusting plates can move relative to each other, thereby causing the connecting plate to move together and causing the two inclined plates in the groove to move relative to each other. This allows the inclined plates to be adjusted to the left and right ends of the tire after the tire of the traffic equipment to be repaired is placed in the groove, thus fixing the tire in the groove and ensuring the stability of the traffic equipment on the work platform during maintenance.

[0012] A further improvement is that the adjustment unit includes a rear side plate, a front side plate, a fixed rod, a sliding rod, a rotating rod, a round shaft, a baffle, and a telescopic component. The rear side plate is fixedly connected to the upper side of the base plate and the lower rear end of the working platform. The front side plate is fixedly connected to the upper side of the base plate and the lower front end of the working platform. The fixed rod is fixedly connected to the left end of the adjacent side of the rear side plate and the front side plate. The sliding rod is connected to the right end of the adjacent side of the rear side plate and the front side plate. The rotating rod is connected to the outer end of the fixed rod and the sliding rod. The round shaft is connected to the inner middle position of the rotating rod. The baffle is fixedly connected to the front and rear ends of the round shaft. The telescopic component is fixedly connected to the upper middle position of the base plate.

[0013] A further improvement is that a rotating hole is provided in the middle of the inner part of the rotating rod, the outer side of the circular shaft is rotatably connected to the inner side of the rotating hole, and the outer side of the rotating rod is slidably connected to the side of the baffle near the circular shaft. Furthermore, two rotating rods are connected to the outer side of each circular shaft. This ensures that the two rotating rods on the outer side of the circular shaft can only rotate around the circular shaft between the baffles.

[0014] A further improvement is that a strip groove is formed at the right end of the adjacent side of the rear and front side plates; a first circular hole is formed at the middle of the right end of the output shaft of the telescopic component; second circular holes are formed at the upper and lower ends of the rotating rod; the outer sides of the front and rear ends of the sliding rod are slidably connected to the inner side of the strip groove; the middle of the outer side of the sliding rod is rotatably connected to the inner side of the first circular hole; and the outer sides of the fixed rod and the sliding rod are rotatably connected to the inner side of the second circular hole. Thus, when the output shaft of the telescopic component is activated and moves, it drives the sliding rod to slide along the inner side of the strip groove, thereby changing the distance between the fixed rod and the sliding rod, causing the rotating rod to rotate relative to the circular axis, and simultaneously moving the upper working platform to adjust the working height according to the needs of the worker.

[0015] A further improvement is that an anti-slip pad is fixedly connected to the outer side of the ramp. Therefore, when the ramp is moved to the outside of the tire of the transportation equipment to fix the tire, the anti-slip pad on the outer side of the ramp contacts the outer side of the tire, allowing the tire to be more firmly fixed to the inside of the groove.

[0016] In summary, this application discloses a maintenance platform for environmental protection engineering in transportation.

[0017] This technical solution involves starting the motor and rotating its output shaft to drive the second threaded rod and the first threaded rod to rotate together. This causes the two outer adjusting plates to move relative to each other, thereby causing the connecting plate to move together and causing the two inclined plates in the groove to move relative to each other. This allows the tire of the traffic equipment to be repaired to be placed in the groove, and then the inclined plates to be adjusted to the left and right ends of the tire's outer side to fix the tire in the groove, thus ensuring the stability of the traffic equipment on the work platform during maintenance.

[0018] Furthermore, by activating the telescopic component, the output shaft moves, causing the sliding rod to slide along the inner side of the slot, thereby changing the distance between the fixed rod and the sliding rod, causing the rotating rod to rotate relative to the circular axis, and simultaneously moving the upper working platform to adjust the working height according to the needs of the workers.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A maintenance platform for environmental protection engineering in transportation includes a base plate 1 and casters 2. The casters 2 are fixedly connected to the four lower corners of the base plate 1. A working platform 3 is provided on the upper end of the base plate 1. A maintenance mechanism is connected to the upper end of the base plate 1. The maintenance mechanism includes a fixing unit and an adjustment unit. The fixing unit is located on the upper end of the working platform 3, and the adjustment unit is located between the base plate 1 and the working platform 3.

[0029] The fixing unit includes an inclined plate 401, a slider 402, a motor 403, a fixing block 404, a bearing 405, a first threaded rod 406, a second threaded rod 407, an adjusting plate 408, and a connecting plate 409. The inclined plate 401 is connected to the upper end of the working platform 3. The slider 402 is fixedly connected to the middle of the front and rear sides of the inclined plate 401. Grooves are formed at the four corners of the upper end of the working platform 3. Slide grooves are formed at the front and rear ends of the grooves inside the working platform 3. The front and rear sides of the lower end of the inclined plate 401 are slidably connected to the inner side of the groove, and the outer side of the slider 402 is slidably connected to the inner side of the slide groove. Thus, when the inclined plate 401 slides inside the groove, the sliders 402 at its front and rear ends slide inside the slide groove, thereby limiting the movement of the inclined plate 401.

[0030] Motor 403 is symmetrically fixedly connected to the middle of the front and rear sides of the working platform 3. Fixing block 404 is fixedly connected to the left and right ends of the front and rear sides of the working platform 3. Bearing 405 is fixedly connected to the inner side of fixing block 404. First threaded rod 406 is fixedly connected to the inner side of bearing 405. Second threaded rod 407 is fixedly connected to the end of first threaded rod 406 away from bearing 405. Adjusting plate 408 is connected to the outer ends of first threaded rod 406 and second threaded rod 407. Connecting plate 409 is fixedly connected to the upper end of adjusting plate 408. The lower inner end of adjusting plate 408 has a threaded hole. The outer sides of first threaded rod 406 and second threaded rod 407 are threaded to the inner side of the threaded hole. The output shaft end of motor 403 is fixedly connected to the end of second threaded rod 407 away from first threaded rod 406. The side of connecting plate 409 away from adjusting plate 408 is fixedly connected to the outer side of inclined plate 401. First threaded rod 406 and second threaded rod 407 are symmetrical. When the output shaft of the motor 403 is started and rotates, it drives the second threaded rod 407 and the first threaded rod 406 to rotate together. This causes the two outer adjusting plates 408 to move relative to each other, which in turn causes the connecting plate 409 to move together. This allows the two inclined plates 401 in the groove to move relative to each other. After the tire of the traffic equipment to be repaired is placed in the groove, the inclined plates 401 are adjusted to the left and right ends of the tire to fix the tire in the groove, thus ensuring the stability of the traffic equipment on the work platform 3 during maintenance.

[0031] Example 2:

[0032] Based on Embodiment 1: The adjustment unit includes a rear side plate 501, a front side plate 502, a fixed rod 503, a sliding rod 504, a rotating rod 505, a round shaft 506, a baffle 507, and a telescopic component 508. The rear side plate 501 is fixedly connected to the upper side of the base plate 1 and the lower rear end of the working platform 3. The front side plate 502 is fixedly connected to the upper side of the base plate 1 and the lower front end of the working platform 3. The fixed rod 503 is fixedly connected to the left end of the adjacent side of the rear side plate 501 and the front side plate 502. The sliding rod 504 is connected to the right end of the adjacent side of the rear side plate 501 and the front side plate 502. The rotating rod 505 is connected to the outer end of the fixed rod 503 and the sliding rod 504. The round shaft 506 is connected to the inner middle position of the rotating rod 505. The baffle 507 is fixedly connected to the front and rear ends of the round shaft 506. The telescopic component 508 is fixedly connected to the upper middle position of the base plate 1. The telescopic component 508 is a hydraulic cylinder. A rotating hole is provided in the middle of the interior of the rotating rod 505. The outer side of the circular shaft 506 is rotatably connected to the inner side of the rotating hole. The outer side of the rotating rod 505 is slidably connected to the side of the baffle 507 near the circular shaft 506. Two rotating rods 505 are connected to the outer side of each circular shaft 506. This ensures that the two rotating rods 505 on the outer side of the circular shaft 506 can only rotate around the circular shaft 506 between the baffles 507.

[0033] A strip-shaped groove is provided on the right end of the adjacent side of the rear side plate 501 and the front side plate 502. A first circular hole is provided in the middle of the right end of the output shaft of the telescopic component 508. A second circular hole is provided at both the upper and lower ends of the rotating rod 505. The outer sides of the front and rear ends of the sliding rod 504 are slidably connected to the inner side of the strip-shaped groove. The middle of the outer side of the sliding rod 504 is rotatably connected to the inner side of the first circular hole. The outer sides of the fixed rod 503 and the sliding rod 504 are rotatably connected to the inner side of the second circular hole. Thus, when the output shaft of the telescopic component 508 is activated, it can drive the sliding rod 504 to slide along the inner side of the strip-shaped groove, thereby changing the distance between the fixed rod 503 and the sliding rod 504, causing the rotating rod 505 to rotate relative to the circular shaft 506, and at the same time driving the upper working platform 3 to move, so as to adjust the working height according to the needs of the operator.

[0034] Example 3:

[0035] Based on Embodiment 1: An anti-slip pad is fixedly connected to the outer side of the ramp 401. Thus, when the ramp 401 is moved to the outside of the tire of the transportation equipment to fix the tire, the anti-slip pad on the outside of the ramp 401 contacts the outside of the tire, which makes the tire more firmly fixed to the inside of the groove.

[0036] Working principle: In use, first push the platform as a whole to move to the working position through the universal wheels 2 at the bottom, then lock the universal wheels 2. Next, place the traffic equipment to be repaired on the working platform 3 so that the tire of the traffic equipment is in the groove. Then start the motor 403 and its output shaft rotates, driving the first threaded rod 406 and the second threaded rod 407 to rotate together. At the same time, the adjusting plate 408 moves and drives the inclined plate 401 to move towards the tire. After the inclined plate 401 moves to the outer end of the tire, the traffic equipment is fixed to the upper end of the working platform 3. Then the traffic equipment is inspected and repaired.
