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
The present invention relates to the hydraulic system mechanically using on a kind of ore deposit, the present invention especially relates to a kind of remote control grab bucket double hydraulic system.
Background technique
Conventional remote control grab bucket is only with a set of hydraulic system, but due to the applying working condition very severe of remote control grab bucket, frequency of utilization is very high, and hydraulic system requires very high to sealing and spatter property, once conventional remote control grab bucket hydraulic system is damaged, service cycle is long, has a strong impact on progress of cargo work, has reduced manufacturing efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can change rapidly, avoid the remote control grab bucket double hydraulic system that affects progress of cargo work, can increase work efficiency.
According to technological scheme provided by the invention, described remote control grab bucket double hydraulic system, on remote control grab bucket crossbeam, be fixed with fuel tank and operating cylinder, in fuel tank, be provided with working solution pressure valve piece, working solution pressure valve piece is communicated with fuel tank, and operating cylinder is connected by working hydraulic pressure pipeline with working solution pressure valve piece, is provided with reserve liquid pressure valve piece in fuel tank, on remote control grab bucket crossbeam, be fixed with oil cylinder for subsequent use, oil cylinder for subsequent use is connected by redundant hydraulic pipeline with reserve liquid pressure valve piece.
On remote control grab bucket crossbeam, operating cylinder and oil cylinder for subsequent use are and are symmetrical set.
The present invention has ensured that remote control grab bucket in use keeps a set of hydraulic system to use always, a set of hydraulic system is normally for subsequent use, once a set of hydraulic system is damaged, can change other a set of hydraulic system at once and use, can not affect normal manufacturing schedule, improve the efficiency of loading and unloading.
Brief description of the drawings
Fig. 1 is plan view of the present invention.
Fig. 2 is plan view of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This remote control grab bucket double hydraulic system, on remote control grab bucket crossbeam 1, be fixed with fuel tank 2 and operating cylinder 3, in fuel tank 2, be provided with working solution pressure valve piece 4, working solution pressure valve piece 4 is communicated with fuel tank 2, operating cylinder 3 is connected by working hydraulic pressure pipeline 5 with working solution pressure valve piece 4, in fuel tank 2, be provided with reserve liquid pressure valve piece 6, on remote control grab bucket crossbeam 1, be fixed with oil cylinder 7 for subsequent use, oil cylinder 7 for subsequent use is connected by redundant hydraulic pipeline 8 with reserve liquid pressure valve piece (6).
On remote control grab bucket crossbeam 1, operating cylinder 3 is and is symmetrical set with oil cylinder 7 for subsequent use.
Remote control grab bucket is in normal using process, provide hydraulic coupling by fuel tank 2, operating cylinder 3, working solution pressure valve piece 4 with the hydraulic system of working that working hydraulic pressure pipeline 5 forms, the standby hydraulics being made up of fuel tank 2, reserve liquid pressure valve piece 6, oil cylinder for subsequent use 7 and redundant hydraulic pipeline 8 is normally for subsequent use, once hydraulic system of working damages, can change standby hydraulics uses at once, can not affect normal manufacturing schedule, improve like this efficiency of loading and unloading.
