AI Technical Summary

Problems solved by technology

Conventional electric control or electro-hydraulic control reversing valves with handles, due to structural limitations, cannot be positioned after manual reversing, and the operation is inconvenient. Even operations that require complex requirements such as steering cannot be completed manually at this time.

Abstract

The embodiment of the invention discloses a hand-operated electronic control multi-way valve assembly, a hydraulic system and a rubber-tired tracklaying crane. The hydraulic system comprises a hydraulic oil tank assembly 1, an oil suction stop valve 2, an oil pump motor set 3, an oil outlet check valve 4, a hand-operated electronic control multi-way valve 5, a hand-operated electronic control multi-way valve 6, a synchronous valve 7 and a steering motor 8 which are connected with one another. The hand-operated electronic control multi-way valve 5 comprises an overflow valve 51, a first check valve 52, a second check valve 55, a two-position three-way hand-operated reversing valve 53 with a positioning function, a two-position three-way electronic control valve 54 with a handle, a pressurereduction valve 56, three-position four-way electro-hydraulic control valves 57 with handles, and a third check valve 58. A first work oil port of the two-position three-way hand-operated reversing valve 53 with the positioning function, a first work oil port of the two-position three-way electronic control valve 54 with the handle, the neutral position normally-opened three-position four-way electro-hydraulic control valves 57 with the handles and the oil return backpressure check valve 58 communicate with one another and are connected with an oil return port.

Description

technical field [0001] The invention relates to the field of power transmission and distribution, in particular to a manual electronically controlled multi-way valve assembly and a hydraulic system of a tire-type track-laying crane. Background technique [0002] Ballastless track is an advanced and complicated technology. When laying track in tunnels, the traditional wheel-type track laying process is complicated, with many procedures and low efficiency, and different equipment is required for track laying and concrete pouring. Due to the limitation of tunnel space and conditions, the requirements for equipment and its control methods are relatively high. Based on efficiency, space, safety and emergency, etc., it is required to be able to control both manually and wirelessly. Conventional electric control or electro-hydraulic control reversing valves with handles, due to structural limitations, cannot be positioned after manual reversing, and the operation is inconvenient. E...
