Description

Technical Field

[0001] This utility model relates to an auxiliary device for the maintenance of manual brakes on railway freight cars, specifically a mobile platform for the maintenance of manual brakes on railway freight cars. Background Technology

[0002] There are several types of manual handbrakes for railway freight cars, including NSW type, FSW type, foot-operated, chain-type, and wheel-type. The FSW type handbrake is a new type of railway freight car handbrake, featuring braking, phased release, and rapid release functions. It is labor-saving, easy to operate, and has good safety. The NSW type handbrake is a modified version of the FSW type, retaining its advantages while simplifying the structure and adding a locking device. It has better anti-slip function and improves the safety of parking freight cars.

[0003] Currently, when performing maintenance on manual brakes at the depot, whether it's disassembly, installation, testing, or painting and welding repairs on the car body, all require working at height. These tasks primarily utilize elevated benches or handcarts, which are mostly self-made steel and wood structures welded by workers. These structures are bulky, difficult to access, and pose high safety risks. Furthermore, disassembling and installing manual brakes requires three people and an overhead crane to work at height, as lifting the brakes is extremely difficult and carries significant safety risks. Summary of the Invention

[0004] This utility model addresses the problem of time-consuming and labor-intensive disassembly and installation of manual brakes in railway depots by providing a mobile platform for the maintenance of manual brakes for railway freight cars.

[0005] This utility model is achieved using the following technical solution: a mobile platform for the maintenance of manual brakes on railway freight cars, comprising a platform frame, a lifting platform, a robotic arm, a hydraulic lifting mechanism, a lifting controller, and a lifting support slide; the bottom of the platform frame is equipped with a wheel set, the platform frame is equipped with a lifting support slide and a hydraulic lifting mechanism, the lifting platform is connected to the lifting support slide, the lifting end of the hydraulic lifting mechanism is connected to the lifting platform, the hydraulic lifting mechanism is equipped with a lifting controller, the left and right sides of the lifting platform are equipped with guardrails, the rear side is equipped with a safety gate, and the front side is equipped with a handrail. A robotic arm is installed on the inner side of the guardrail on one side of the lifting platform. The robotic arm includes a three-jaw chuck, with a first hinge seat connected to the back of the three-jaw chuck. The first hinge seat is hinged to the end of an RV reducer. The input shaft of the RV reducer is connected to a rotary handle, and the output shaft of the RV reducer is connected to a second hinge seat. Two parallel support rods are hinged between the second and third hinge seats. A gas spring support rod is hinged between the upper support rod and the third hinge seat, and a gas spring support rod is hinged between the lower support rod and the second hinge seat. The third hinge seat is also hinged to a mounting base, which is installed on the guardrail on one side of the lifting platform.

[0006] This mobile maintenance platform is easy to move and allows workers to perform high-altitude operations, including the disassembly and installation of manual brakes. The robotic arm, through a three-jaw chuck, can perform prescribed actions such as gripping, lifting, and lowering the manual brake turntable, facilitating the lifting of the manual brake and thus making it easier to disassemble and install it.

[0007] The aforementioned mobile platform for the maintenance of manual brakes on railway freight cars includes a support foot assembly at the bottom of the platform frame. This assembly comprises multiple support feet, each consisting of a screw and a base. The screw is threadedly connected to the platform frame, and the base is fixed to the bottom of the screw. The support feet are evenly distributed around the perimeter of the platform frame. When the mobile platform moves, the support feet are suspended in the air, while the base contacts the ground during maintenance, preventing arbitrary movement of the platform.

[0008] The aforementioned mobile platform for the maintenance of manual brakes on railway freight cars also includes a front and rear moving mechanism. The front and rear moving mechanism includes a slide rail and a slider. The slide rail is fixed on a side guardrail, and the slider is slidably mounted on the slide rail. A mounting base is connected to the slider.

[0009] This utility model adopts a mobile maintenance vehicle, which can meet the needs of disassembling and assembling railway manual brakes and is suitable for maintenance operations such as section maintenance, factory maintenance, and station maintenance to replace manual brakes.

[0019] The railway freight car manual brake maintenance mobile platform includes a platform frame 1, a lifting platform 2, a robotic arm 3, a hydraulic lifting mechanism 4, a lifting controller 5, a safety gate 6, a lifting support slide 7, a support foot assembly 8, and a front and rear moving mechanism 9.

[0020] The platform frame 1 adopts a four-wheel structure. The bottom of the platform frame 1 has a front rolling wheel and two rear main wheels. The bottom of the platform frame 1 is also equipped with a support foot assembly 8, which includes multiple support feet. Each support foot includes a screw and a base. The screw is threaded to the platform frame 1, and the base is fixed to the bottom of the screw. The multiple support feet are evenly distributed around the platform frame 1. The platform frame 1 is equipped with a lifting support slide 7 and a hydraulic lifting mechanism 4. The lifting support slide 7 is connected to the lifting platform 2. The lifting end of the hydraulic lifting mechanism 4 is connected to the lifting platform 2. The hydraulic lifting mechanism 4 is also equipped with a lifting controller 5. The left and right sides of the lifting platform 2 are equipped with guardrails, the rear side is equipped with a safety door 6, and the front side is equipped with a handrail. The inner side of one side guardrail of the lifting platform 2 is equipped with a front and rear moving mechanism 9, which includes a slide rail and a slider. The slide rail is fixed to one side guardrail, and the slider is slidably set on the slide rail. The slider is connected to a robotic arm 3.

[0021] The robotic arm 3 includes a three-jaw chuck 31, an RV reducer 33, and a rotary handle 34. The back of the three-jaw chuck 31 is connected to a first hinge seat 32. The end of the RV reducer 33 is hinged to the first hinge seat 32. The input shaft of the RV reducer 33 is connected to the rotary handle 34. The output shaft of the RV reducer 33 is connected to a second hinge seat 35. Two parallel vertical support rods 36 are hinged between the second hinge seat 35 and the third hinge seat 38. A gas spring support rod 37 is hinged between the upper support rod 36 and the third hinge seat 38. A gas spring support rod 37 is hinged between the lower support rod 36 and the second hinge seat 35. The third hinge seat 38 is also hinged to a mounting base 39, which is connected to a slider.

[0022] Manual brakes are typically mounted high in the truck bed via a mounting base. Workers operate the brakes and locks by rotating a turntable on the mounting base. Maintenance typically involves disassembling an old manual brake and installing a new one. During maintenance, the platform is first moved to the work position. The worker stands on the lifting platform 2 and uses the lifting controller 5 to raise the platform 2 to a suitable height. The three-jaw chuck 31 of the robotic arm 3 is aligned with the turntable of the manual brake. Rotating the ring handle on the three-jaw chuck 31 rotates the flat screw disc inside the chuck. The rotation of the flat screw disc causes the three jaws to converge and grip the turntable of the manual brake. The worker then removes the manual brake. After removal, the support rod 36 can be swung up and down to position the manual brake at a certain height above the lifting platform 2. Then, the rotary handle 34 rotates, causing the RV reducer 33 to rotate. Move the robotic arm 3 until it is perpendicular to the lifting platform 2 (the rotation plane of the RV reducer 33 is perpendicular to the support rod 36), and at this time, the turntable of the manual brake is exactly on the lifting platform 2. Rotate the ring handle on the three-jaw chuck 31 to drive the flat screw disc inside the chuck to rotate. The rotation of the flat screw disc causes the three jaws to move away from the center, and the three-jaw chuck 31 releases the turntable of the manual brake. The above process completes the disassembly of the old manual brake. Then, use the three-jaw chuck 31 to hold the turntable of the new manual brake. After adjusting it to the installation position using the RV reducer 33 and the support rod 36, the new manual brake is installed. The whole process realizes the maintenance of the manual brake. The front and rear position of the robotic arm 3 can be adjusted by the front and rear moving mechanism 9. The structure composed of the second hinge seat 35, the third hinge seat 38 and the support rod 36 can be slightly adjusted in the vertical direction. With the maintenance mobile platform of this utility model, one person can carry out maintenance work on the manual brake, which is convenient for working at height and does not require the cooperation of an overhead crane.

[0023] The robotic arm of this utility model's mobile maintenance platform can perform prescribed actions such as clamping, lifting, and lowering through manual adjustment. The hydraulic lifting mechanism 4 and the lifting support slide 7 utilize pneumatic-hydraulic control technology to raise and lower the lifting platform 2, ensuring the working height. This platform can perform mobile maintenance operations on manual brakes for railway freight cars, and has functions for dismantling old brakes, replacing old ones, and short-distance transport. Simultaneously, the platform can also perform functions such as freight car painting, elevation climbing, and vehicle maintenance.
