Embodiment Construction

[0017] The specific implementation will be described below in conjunction with the accompanying drawings.

[0018] The fork structure of the loader in the present invention is as follows: figure 1 As shown, the holding fork 1 includes a lower fork body 13, and the two ends of the lower fork body 13 are respectively connected with a left upper fork body 11 and a right upper fork body 12 through pin shafts, and a left upper fork body 11 and a lower fork body 13 are connected with a left Hydraulic cylinder 14, right upper fork body 12 and lower fork body 13 are connected with right hydraulic oil cylinder 15, and the stretching of left hydraulic oil cylinder 14 and right hydraulic oil cylinder 15 drives left upper fork body 11, right upper fork body 12 to swing up and down respectively.

[0019] The hydraulic control system of the fork 1 is as follows: figure 1 As shown, it includes a multi-way valve 26, a left pilot proportional valve 231, a right pilot proportional valve 232, a...

Abstract

The invention relates to a loading machine holding fork hydraulic system. The problem that a holding fork is damaged by yawing force which is generated from the current loading machine holding fork during the operating process is solved. The loading machine holding fork hydraulic system comprises a left hydrocylinder, a right hydrocylinder and a multitandem valve. A multitandem valve comprises a left hydrocylinder control linkage, a right hydrocylinder control linkage, a left pilot proportional valve and a right pilot proportional valve. Two pilot oil opens of the left and the right pilot proportional valves are connected with a left and a right control ends of the left and the right hydrocylinder control linkages correspondingly. According to the loading machine holding fork hydraulic system, the stretching and clamping of an upper fork body can be harmoniously controlled, the fact that the single side of the upper fork body is deformed and damaged by the yawing force in the operating process is avoided, and the service life of the holding fork system is prolonged.

Description

technical field [0001] The invention relates to a hydraulic system for holding a fork, more specifically, to a hydraulic system for holding a fork of a loader. Background technique [0002] The fork is one of the many attachments of the loader. There are usually two upper forks on the fork, and the two upper forks are each driven by a hydraulic cylinder. The two hydraulic cylinders are connected to the third unit in the hydraulic system of the loader through pipelines, and the two hydraulic cylinders are connected to the third unit to form a parallel oil circuit, that is, two oil cylinders are controlled simultaneously through a control valve. [0003] In the existing fork holding hydraulic system, the two upper fork bodies are opened or clamped by the same hydraulic oil circuit. During operation, especially when the two ends of the clamped material have a large difference in size, the center of gravity deviates, and the clamping process In the middle, it will cause the upp...
