Problems solved by technology

[0002] The conventional remote control grab only has one set of hydraulic system, but because the working conditions of the remote control grab are very harsh and the frequency of use is very high, and the hydraulic system has high requirements for sealing and cleanliness, once the hydraulic system of the conventional remote control grab is damaged , the maintenance cycle is long, which seriously affects the loading and unloading progress and reduces the production efficiency

Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific examples.

[0010] The dual hydraulic system of the remote control grab has a fuel tank 2 and a working cylinder 3 fixed on the beam 1 of the remote control grab, and a working hydraulic valve block 4 is arranged in the fuel tank 2. The working hydraulic valve block 4 is connected to the fuel tank 2, and the working cylinder 3 and the working The hydraulic valve block 4 is connected through the working hydraulic pipeline 5. There is a spare hydraulic valve block 6 in the fuel tank 2. A spare oil cylinder 7 is fixed on the remote control grab beam 1. The spare oil cylinder 7 and the spare hydraulic valve block (6) pass through the spare hydraulic valve block (6). The hydraulic pipeline 8 is connected.

[0011] On the remote control grab beam 1, the working oil cylinder 3 and the spare oil cylinder 7 are left and right symmetrically arranged.

[0012] During normal use of the remote contro...

Abstract

The invention relates to a dual-hydraulic system of a remote-control grab bucket. An oil tank and an operating cylinder are fixed to a transverse beam of the remote-control grab bucket. A working hydraulic valve is arranged in the oil tank and communicated with the oil tank. The operating cylinder is connected with the working hydraulic valve through a working hydraulic pipe. A standby hydraulic valve is arranged in the oil tank. A standby oil cylinder is fixed to the transverse beam of the remote-control grab bucket and connected with the standby hydraulic valve through a standby hydraulic pipe. By means of the dual-hydraulic system, it is guaranteed that in the use process of the remote-control grab bucket, one of hydraulic system bodies is kept used all the time, and the other one of the hydraulic system bodies is kept in the normally-standby condition all the time; once one of the hydraulic system bodies is damaged, the other one of the hydraulic system bodies can be immediately switched for use, the normal production schedule can not be influenced, and the loading-unloading efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic system used on mine machinery, in particular to a dual-hydraulic system with remote control grab buckets. Background technique [0002] The conventional remote control grab only has one set of hydraulic system, but because the working conditions of the remote control grab are very harsh and the frequency of use is very high, and the hydraulic system has high requirements for sealing and cleanliness, once the hydraulic system of the conventional remote control grab is damaged , The maintenance cycle is long, which seriously affects the loading and unloading progress and reduces the production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a dual hydraulic system for remote control grabs that can be quickly replaced, avoids affecting the progress of loading and unloading, and can improve work efficiency. [0004] Accor...
