Description

Technical Field

[0001] This invention relates to the field of tippler testing, and more specifically, to a tippler railway freight car pressure testing device and testing method with a fixed structure. Background Technology

[0002] A tippler is a large mechanical device used to unload bulk materials from open railway wagons. It is a loading and unloading machine that can tilt or tilt rail vehicles to unload materials. It is suitable for ports with high transport volumes and industrial sectors such as metallurgy, coal, and thermal power. During use, the tippler suffers from problems due to the narrow size of the pressure beam, resulting in a small contact area with the upper side beam of the vehicle. Combined with the rapid descent of the vehicle towards the pressure beam, the impact force is large, causing deformation and damage to the upper side beam. Existing pressure force detection structures receive the impact force of the vehicle approaching the pressure beam through pressure sensors, typically bolted to one side of the upper side beam. However, because pressure sensors are susceptible to environmental influences, they require frequent maintenance, involving disassembly or installation with a screwdriver, which is cumbersome. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the susceptibility of pressure sensors to environmental influences, which necessitates frequent maintenance and cumbersome disassembly or installation using screwdrivers. This invention provides a railway freight car pressure detection device with a fixed structure for tippers, thus solving the above-mentioned deficiencies and facilitating its use.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0007] The docking mechanism includes an insert plate inserted into the insert slot and a frustum-shaped strip installed on the top of the insert plate. A limited displacement groove is formed inside one side of the frustum-shaped strip. A limit plate is slidably installed inside the limited displacement groove. An insert block is installed on one side of the limit plate and matches the limit groove. A compression spring for rebound is installed between one side of the limit plate and the inner wall of the limited displacement groove.

[0008] Preferably, the placement mechanism includes a receiving strip installed on one side of the insertion plate and a slot opened on one side of the receiving strip. An inner groove is opened on one side of the slot and the inner groove extends through the other side of the receiving strip. A wire hole is opened at the top of the receiving strip.

[0009] Preferably, both sides of the inner wall of the inner groove are provided with limiting grooves for limiting the position. A push plate is slidably installed inside the inner groove. A threaded rod is threadedly connected to the middle end of the insert plate, and one end of the threaded rod is movably installed on one side of the push plate. Rotating the limiting groove causes the push plate to move inside the inner groove.

[0010] Preferably, limit sliders are installed on both sides of the push plate, and the limit sliders are slidably installed inside the limit groove to limit the range of movement of the push plate.

[0011] Preferably, the pushing mechanism includes an inner slide plate slidably installed inside the inner groove and a placement frame installed on one side of the inner slide plate, wherein the bottom end of the placement frame contacts the bottom end of the groove, and rubber blocks for limiting are installed on both sides of the inner side of the placement frame.

[0012] Preferably, the upper side beam has a through hole at its middle end, and the through hole is aligned with the slot.

[0013] Preferably, a testing method for a railway freight car pressure detection device with a fixed structure includes the following steps:

[0014] S1. Insert the test piece into the inside of the placement frame. Rubber blocks on both sides inside the placement frame clamp and limit the test piece. Push the placement frame into the inside of the inner groove, and the test piece moves into the inside of the inner groove.

[0015] S2, the upward docking mechanism and the placement mechanism, the platform-shaped strip is inserted into the inside of the mounting slot, and the pressing mounting block is moved into the inside of the displacement limiting groove;

[0016] S3. The position of the docking mechanism and the placement mechanism is fixed by inserting a compression spring into the limiting groove. After the fixation is completed, the slot and the through hole are aligned, and the placement frame moves due to the pushing force of the push plate on the inner slide plate.

[0017] S4. Rotate the threaded rod to make the push plate move inside the inner groove, and the limiting slider moves inside the limiting slide groove. The limiting slider and the limiting slide groove limit the movement angle of the push plate.
