Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those skilled in the art can understand that the present invention is not limited to specific embodiments.

[0020] like figure 1 As shown, when the lifting device of the present invention works, the solenoid valve 3 controls the liquid inlet and liquid return respectively, and the two hydraulic cylinders 6 rise and fall simultaneously, and the hydraulic control check valve 4 plays the role of a hydraulic lock when the cylinder is fixed. The hydraulically controlled one-way valve 4 can be reversely opened under the action of the pilot hydraulic pressure of the solenoid valve to lower the oil cylinder.

[0021] Stop valve 1 is used to switch the liquid supply pipeline. Filter 2 is used for liquid filtration of the liquid supply pipeline. The overflow valve 5 is used to adjust the system pressure.

[0022] like figure 2 As show...

Abstract

The invention relates to a lifting device of a transferring machine head for installing a fully-mechanized working surface. The lifting device comprises two hydraulic oil cylinders, two brackets, a valve set and a cross beam. The brackets and the hydraulic oil cylinders are used in a matching manner and support the cross beam at the upper part. The valve set controls the synchronous motion of the hydraulic oil cylinders so as to keep the cross beam horizontal. By utilizing the lifting device in the invention, the transferring machine head can be stably lifted to the installing position for positioning, so as to ensure safe and high-speed installing work.

Description

technical field [0001] The invention relates to a lifting device for a head of a reloading machine, in particular to a lifting device for a head of a reloading machine used for installing a fully mechanized mining face. Background technique [0002] When installing the loader in the fully mechanized mining face, the weight of the equipment is heavy, the roadway space is narrow, and the installation position is higher than the ground surface and suspended on the tail of the self-moving machine with a height of more than 1 meter, which makes the installation of the equipment difficult, labor-intensive and time-consuming. Lifting the head of the loader Sometimes even cause personal injury and equipment damage. [0003] The existing technology is that the vehicle lifts the head of the reloading machine, and builds a walking ramp for the transport vehicle at the installation site. The vehicle climbs up the installation site along the ramp, and then uses the chain hoist to lift th...
