Embodiment 1

[0033] The combined valve group for cargo bucket lifting control provided by the present invention includes an H-type two-position four-way electromagnetic reversing valve 1 and a three-position four-way electromagnetic reversing valve 2, wherein the H-type two-position four-way electromagnetic reversing valve 1 It is worth noting that the high-pressure oil source mentioned here is the oil pump that extracts the hydraulic oil in the hydraulic workstation, that is, the P port of the H-type two-position four-way electromagnetic reversing valve 1 is connected to the oil pump. The outlet of the H-type two-position four-way electromagnetic reversing valve 1 is connected to conduction to inject high-pressure hydraulic oil into the H-type two-position four-way electromagnetic reversing valve 1, and the T port of the H-type two-position four-way electromagnetic reversing valve 1 is connected to the oil tank to guide the hydraulic oil back to the oil tank , the T and P ports of the thre...

Embodiment 2

[0045] This embodiment provides a truck. The truck uses the combined valve group for the lifting control of the cargo bucket provided in Embodiment 1 to control the lifting oil circuit of the cargo bucket. Therefore, the truck is more convenient to manufacture and more convenient to maintain.

Abstract

The invention relates to a combined valve bank for lifting control of a cargo bucket and a truck, belongs to the technical field of transport vehicles, and solves the technical problems that a four-position electromagnetic proportional pilot control valve used in a bucket lifting system of a truck cannot be produced in China, so the product supply period is long, and the maintenance is difficult.The combined valve bank comprises an H-shaped two-position four-way electromagnetic reversing valve and a three-position four-way electromagnetic reversing valve, a port P of the H-shaped two-positionfour-way electromagnetic reversing valve is connected with a high-pressure oil source, a port T of the H-shaped two-position four-way electromagnetic reversing valve is connected with an oil tank, and a port T and a port P of the three-position four-way electromagnetic reversing valve are connected with two working oil ports; and two working oil ports of the three-position four-way electromagnetic reversing valve are respectively connected with a large cylinder and a small cylinder of an oil cylinder of the lifting bucket. The combined valve bank can replace a four-position electromagnetic proportional pilot control valve to control the lifting process of the truck bucket and is easy to obtain in China, so the goods supply time can be greatly shortened, and the combined valve bank is convenient to replace and maintain.

Description

technical field [0001] The invention belongs to the technical field of transportation vehicles, and in particular relates to a combined valve group and a truck for lifting control of cargo buckets. Background technique [0002] At present, in heavy-duty material transport vehicles, the bucket lifting system mainly uses the imported four-position electromagnetic proportional pilot control valve to control the lifting valve group with flow amplification function, so as to realize the locking, floating, and lifting of the lifting device. Ascent, forced landing and other functions. The imported electric proportional pilot control valve is a four-position valve with complex internal structure, difficult processing and mostly produced abroad, resulting in long product delivery cycle and difficult maintenance. Contents of the invention [0003] The invention provides a combined valve group for cargo bucket lifting control, which is used to solve the problem that the four-positio...
