Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway transportation equipment technology, and in particular to a car-pressing and car-approaching protection device for tippler equipment, which aims to improve the continuity and safety of tippler operations. Background Technology
[0002] The reliability of the car-pressing and car-aligning devices of a tippler directly affects the safety of unloading railway vehicles. Therefore, the positions of the car-pressing and car-aligning devices are monitored in real time using detection elements. However, in practical applications, it has been found that malfunctions and false alarms of the electronic detection elements frequently occur, causing tippler tipping to be interrupted and affecting the continuity and safety of operations. Summary of the Invention
[0003] The purpose of this utility model is to provide a tippler crushing and approaching protection device, which plays an emergency protection role in the event of failure of the tippler crushing and approaching devices, to prevent railway vehicles from derailing or falling off the track during the tippler's tipping process. At the same time, it reduces the dependence of the crushing and approaching devices on the positioning signal, avoids the interruption of tippler tipping due to detection component failure or false alarm, and ensures the continuity and safety of the operation.
[0004] The technical solution of this utility model is implemented as follows: A tipper car crushing and approach protection device includes a crushing protection device and an approach protection device. The crushing protection device includes a first support structure and a wear plate fixed on the first support structure. The first support structure is installed on the tipper end ring, side beam, and top beam to buffer the collision of railway vehicles in the vertical direction of movement. The wear plate leaves a certain gap from the railway vehicle, which is the maximum distance that the railway vehicle can move in the vertical direction. This gap ensures that the railway vehicle will not scrape when passing and that the railway vehicle will not derail when the tipper is overturned. The crushing protection device only functions when the crushing device fails and the railway vehicle displaces in the vertical direction. At this time, the wear plate contacts the railway vehicle, playing a role in buffering and protecting the railway vehicle.
[0005] The car-stopping protection device includes a second support structure, a rotating bumper, a counterweight, and a limiting device. The second support structure is fixed below the side beam. The rotating bumper is mounted on the second support structure and rotates as the tipper flips. The counterweight, mounted on the rotating bumper, is the power source for its rotation. Furthermore, it includes a limiting device mounted on the second support structure to control the rotational stroke of the rotating bumper. When the tipper is in the zero position, the car-stopping protection device does not affect the extension and retraction of the car-stopping plate. After the car-stopping plate extends, the rotating bumper, under the action of the counterweight, begins to rotate as the tipper flips. It stops and remains in the limiting device position, maintaining a certain gap between the rotating bumper and the car-stopping plate. This gap represents the maximum horizontal distance the railway vehicle can move. This gap ensures that the rotating bumper does not rub against the car-stopping plate during rotation and that the railway vehicle does not derail when the tipper flips. When the tipper tilts back to near the zero position, the rotating bumper begins to rotate under the action of the counterweight. When the tipper tilts back to the zero position, the rotating bumper also returns to its initial state and stops protecting the vehicle approach device.
[0006] Compared with existing technologies, this invention has the following advantages: By adding a simple mechanical structure, it reduces reliance on electronic detection components, thus lowering the failure rate. It improves the continuity of unloading operations and equipment utilization. The dual protection design significantly enhances equipment safety. No additional power is required, and it does not increase equipment energy consumption. Attached Figure Description

[0011] like Figure 1 , Figure 2 , Figure 3 This is a specific embodiment of the present invention, which is a tipper vehicle crushing and approach protection device, including a crushing protection device and an approach protection device.
[0012] The car-pressing protection device includes a first support structure 1 and a wear plate 2 fixed on the first support structure 1. The first support structure 1 is installed on the tipper end ring, side beam, and top beam to buffer the collision of railway vehicles in the vertical direction of movement. Each car is equipped with four car-pressing protection devices. The wear plate leaves a certain gap from the railway vehicle, which is the maximum distance that the railway vehicle can move in the vertical direction. This gap ensures that the railway vehicle will not scrape when passing and that the railway vehicle will not derail when the tipper is overturned.
[0013] The car-stopping protection device includes a second support structure 3, a rotating bumper 4, a counterweight 5, and a limiting device 6. The second support structure 3 is fixed below the side beam. The rotating bumper 4 is mounted on the second support structure 3 and rotates as the tipper flips. The counterweight 5 is mounted on the rotating bumper 4 and provides the power for its rotation. The limiting device 6 is mounted on the second support structure 3 and controls the rotation stroke of the rotating bumper 4. When the tipper is in the zero position, the car-stopping protection device does not affect the extension and retraction of the car-stopping plate. After the car-stopping plate extends, the rotating bumper begins to rotate under the action of the counterweight as the tipper flips. It stops and remains in the limiting device position. At this time, a certain gap is maintained between the rotating bumper and the car-stopping plate. This gap is the maximum distance that the railway vehicle can move horizontally. This gap ensures that the rotating bumper does not rub against the car-stopping plate when rotating and that the railway vehicle does not derail when the tipper flips. When the tipper tilts back to near the zero position, the rotating bumper begins to rotate under the action of the counterweight. When the tipper tilts back to the zero position, the rotating bumper also returns to its initial state and stops protecting the vehicle approach device.
[0014] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. All equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be covered within the protection scope of the present utility model.
