Abstract

The invention discloses a telescopic crane cable storage valve group which comprises a valve block, a shuttle valve, a pressure reducing valve, a pilot directional valve, a flow control valve and a balance valve. The valve block is provided with a port A, a port B, a port C, a port D, a port X and a port L; two oil inlets of the shuttle valve are connected with the port A and the port B respectively, and an oil inlet of the pressure reducing valve is connected to an oil outlet of the shuttle valve; the pilot directional valve is a two-position three-way valve and is provided with a P port, a T port, an A1 port and a first pilot port, an oil outlet of the pressure reducing valve is connected to the P port and the first pilot port, and the T port is connected to the L port; the flow control valve comprises a one-way valve and a throttling valve, an oil inlet of the one-way valve and an oil outlet of the throttling valve are connected to the T port, and an oil outlet of the one-way valve and an oil inlet of the throttling valve are connected to the X port; and the balance valve is provided with a first oil port, a second oil port and a second pilot port, the port B is connected to the first oil port, the second oil port is connected to the port D, and the second pilot port is connected to a pipeline between the shuttle valve and the port C. The valve group can control the telescopic hoisting storage cable to be stably laid.

Description

technical field [0001] The invention relates to a telescopic hanging cable storage valve group. Background technique [0002] Telescopic crane is a kind of hoisting device, which is mainly used in the auxiliary retraction and deployment of scientific research equipment and the retraction and deployment of rescue boats and working boats. The use of a telescopic crane can greatly improve the efficiency of retracting and unwinding; the stability of the cable is very important during the cable unwinding process, and the cable storage valve group is widely used in the telescopic crane and is an important part of the telescopic crane. The existing telescopic crane cable storage valve group has the defects of large volume, unstable cable unwinding action, high maintenance cost and inconvenient disassembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect of unsteady operation of telescopic cable storage and ...
