Embodiment Construction

[0016] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] The spherical hinge device of the present invention is used for the connection and guidance of the plunger and the connecting rod of the emulsion pump and the spray pump in mechanized coal mining, such as figure 1 As shown, the spherical hinge device includes a fixed flange 1, a slider 2, a left spherical hinge seat 3, a right spherical hinge seat 4, a ball joint rod 5, a fastening screw 6 and a box slide 7, and the box slide 7. The sliders 2 are all cylindrical, and the ball head of the ball joint rod 5 is inserted into the right ball joint seat 4 with a certain gap between the two. Put them into the bottom of the axial center installation hole of the slider 2; then put the left ball joint seat 3 into the axial...

Abstract

The invention relates to a spherical hinge device, and relates to the technical field of mechanized coal mining and processing. According to the spherical hinge device, through the matching of a spherical hinged seat and a spherical head, a spherical head connecting rod is allowed to swing in the horizontal direction without affecting the linear motion of a sliding block, the lateral force affectof a traditional sliding block form is well eliminated, and operation is more stable; and through a unique multi-point lubrication pore channel design, the sufficient supply and balance of lubricatingoil between the spherical head and the spherical hinged seat are ensured, thus a stable lubricating oil film is formed between the spherical head and the spherical hinged seat, the wear is lowered through the sufficient lubrication between the spherical head and the spherical hinged seat, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanized coal mining and processing, in particular to a spherical hinge device. Background technique [0002] On the existing emulsion pump and spray pump, the connecting and guiding mechanism of the plunger and the crankshaft connecting rod adopts the structure of cylindrical pin and slide block. The connecting rod end does not have the function of self-aligning, which cannot eliminate the influence of lateral force, causing the slider to bear radial load and accelerate the wear of the slider. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to realize a plunger and connecting rod connection and guide device for emulsion pumps and spray pumps in mechanized coal mining with more stable operation and long service life. [0005] (2) Technical solutions [0006] In order to solve the above technical prob...
