Problems solved by technology

[0002] Nowadays, the demand for mining high-inclination coal seams is gradually increasing, and the requirements for the stability of the shearer body are relatively high during the mining process of high-inclination coal seams, but most of the existing shearers are not equipped with special supports for high-inclination coal seam mining system, in the actual coal mining process, the driver can only take corresponding support measures for the coal mining machine body according to the on-site conditions. In the actual use process, the body has poor stability and low safety to varying degrees.
Although there are some support devices on the market, their support effects cannot meet the stability support requirements of the shearer fuselage in the process of coal mining with a large dip angle.
Therefore, there is a lack of a support position self-adjusting hydraulic support device with simple structure, reasonable design, easy installation and operation, and good use effect, which can support the shearer body at different support positions according to actual needs. , and the support position is easy to adjust

Embodiment Construction

[0032] Such as figure 1 , figure 2 and Figure 4As shown, the present invention includes an inclination angle detection unit for detecting the inclination angles of the supported shearer fuselage on the X, Y and Z axes, and a forward slide arranged on the upper part of the front side of the supported shearer fuselage. Moving beam 1, the front hydraulic support mechanism installed under the front side of the front sliding beam 1, the rear sliding beam 2 arranged on the rear upper part of the supported coal shearer fuselage, installed on the rear side of the rear sliding beam 2 The lower rear hydraulic support mechanism drives the front sliding beam 1 to rotate left and right and adjusts the support position of the front hydraulic support mechanism accordingly. The front rotary drive cylinder 3 drives the rear sliding beam 2 to rotate left and right and correspondingly The rear rotary drive cylinder 4 that adjusts the support position of the rear hydraulic support mechanism a...

Abstract

The invention discloses a supporting position self-regulation type hydraulic support device, which comprises an inclination angle detecting unit, a front slipping beam, a back slipping beam, a front hydraulic support mechanism, a back hydraulic support mechanism, a front rotation driving oil cylinder, a back rotation driving oil cylinder and a control box, wherein the inclination angle detecting unit is used for detecting the inclination angle of the machine body of a coal mining machine on X, Y and Z axes; the front slipping beam and the back slipping beam are arranged at the upper parts of the front side and the back side of the machine body of the coal mining machine to be supported; the front hydraulic support mechanism is arranged at the lower part of the front side of the front slipping beam; the back hydraulic support mechanism is arranged at the lower part of the back side of the back slipping beam; the front rotation driving oil cylinder drives the front slipping beam to leftwards and rightwards rotate and regulates the supporting position of the front hydraulic support mechanism; the back rotation driving oil cylinder drives the back slipping beam to rotate and correspondingly regulates the supporting position of the back hydraulic support mechanism; the control box is arranged in a cab of the coal mining machine; and the inclination angle detecting unit is a three-axis acceleration meter. The supporting position self-regulation type hydraulic support device has the advantages that the structure is simple; the design is reasonable; the installation, the distribution, the use and the operation are simple and convenient; the use effect is good; the machine body of the coal mining machine can be supported in different supporting positions according to actual requirements; and the supporting position can be simply and conveniently regulated.
