Rotor type car dumper

Abstract

The invention discloses a rotor type car dumper. The rotor type car dumper comprises a body, a car pressing device, a car abutting device, a hydraulic element assembly, a hydraulic pump station, a hydraulic valve station and a hydraulic pipe, wherein the car pressing device and the car abutting device are arranged on the body; the hydraulic element assembly is arranged in the body and is used for hydraulically driving the car pressing device and the car abutting device; the hydraulic pump station and the hydraulic valve station are separated from a main body and are combined to form a secondary hydraulic system; and the secondary hydraulic system is connected with the hydraulic element assembly through the hydraulic pipe. By using the rotor type car dumper, the failure rate is reduced, the repair process on the hydraulic system of the rotor type car dumper is simplified, the repair time is shortened, the reliability of the hydraulic system is improved, and the operation efficiency of the rotor type car dumper is also improved.

Description

technical field [0001] The invention relates to a rotor type dumper. Background technique [0002] The rotor-type dumper is used to unload the gondola car, and mainly includes a main body 1, a vehicle berth device 4 and a car press device 9 installed on the body 1, a vibrator 3 installed on the car berth device 4, a hydraulic pump station, and a hydraulic valve Station 2 and various connecting lines and control elements. At present, for domestic rotor-type dumpers, most of the hydraulic pump station and hydraulic valve station 2 are installed on the body 1 of the rotor-type dumper, or the hydraulic pump station is installed on the ground and only the hydraulic valve station is installed on the ontology, such as figure 1 with figure 2 shown. [0003] For the situation that the hydraulic pump station 6 is installed on the ground and the hydraulic valve station is installed on the body, the hydraulic pump station 6 and the hydraulic valve station 2 are connected through fo...

AI Technical Summary

Problems solved by technology

In addition, when dumping is performed, a lot of dust will be generated, resulting in the hydraulic pump station 6 and hydraulic valve station 2, as well as various hydraulic components and pipelines, etc. being easily affected, and more dust will accumulate on their surfaces

[0004] In the dumping operation process, the vibrator 3 on the car device 4 will vibrate when turning forward to about 145°, and stop when turning back to 130°, resulting in a vibration time of about 8 seconds. The permanent deformation of the sealing element in the joint is accelerated, and the pre-tightening force of the joint is reduced to cause loosening, which results in frequent oil leakage of the hydraulic pipe joint in the body, and also causes other hydraulic failures

[0005] When a fault occurs in the hydraulic valve station installed on the body, it is necessary to clean the dust accumulated on the box of the hydraulic valve station and open the closed box cover before the fault can be judged and eliminated. The entire fault handling process takes a long time

In addition, when dealing with hydraulic faults in the main body, since a large amount of dust is adhered to the equipment to be repaired, it will fall and disperse when there is a slight vibration. If the material enters the hydraulic system being repaired, it will cause secondary pollution, resulting in a significant hydraulic failure rate. increase

In addition, since the hydraulic valve station is close to the vibration source (that is, the vibrator 3), the loosening of the hydraulic pipeline joints in this part is further accelerated, causing a series of oil leakage and other failures

In addition, there are 8 electrical signals and control elements in the hydraulic valve station connected to the electrical room on the ground through moving cables, and the vibration in the main body will also cause loosening of electrical connectors, wear and tear of line insulation, etc.

When diagnosing and eliminating electrical faults, it is also necessary to clean the accumulated material on the box of the hydraulic valve station and open the closed box cover to perform fault judgment and troubleshooting. Working efficiency of rotor dumper
