Embodiment 1

[0027] Example 1, such as figure 1 , figure 2 , image 3 A combined connection terminal, including a base 1, a cover plate 2 and a cover plate 3, the upper surface of the base 1 is connected by a left convex plane 1.1 and a right concave plane 1.5 to form a stepped surface; the base convex The middle part of the starting plane 1.1 is provided with a first U-shaped groove 1.2, which is used to place the middle part of the dumbbell pin of the connector, and has a certain gap with the middle part of the dumbbell pin, so that a certain amount of activity can be connected between the grooves to ensure The middle groove is bent horizontally and vertically at a certain angle. The dumbbell pin connection is a kind of flexible connection, which can adapt to a certain degree of uneven ground or push and pull bending, can withstand high tensile, bending and shearing forces, etc., and is easy to disassemble. There is also an inline groove 1.3 in the middle of the raised plane 1.1 of t...

Abstract

The invention belongs to the field of connecting pieces of underground conveying equipment, and in particular, relates to a combined connecting end and a preparation method thereof. The combined connecting end comprises a base (1), a cover plate (2) and a cover plate (3), wherein the cover plate (2) and the cover plate (3) are fixedly connected to the base (1); the upper surface of the base (1) is formed to a step-shaped surface by connecting a left convex plane (1.1) with a right lower concave plane (1.5); a first U-shaped groove (1.2) and a horizontal groove (1.3) are formed in the middle part of the base convex plane (1.1); a sigma-shaped groove (1.6) is formed in the middle part of the low concave plane (1.5); and the first U-shaped groove (1.2), the horizontal groove (1.3) and the sigma-shaped groove (1.6) are communicated. The invention further discloses a manufacturing method of the combined connecting end, and solves the technical problems of complex structure, easy wear in casting and difficult casting of an end in the prior art.

Description

technical field [0001] The invention belongs to the field of connectors for downhole conveying equipment, and in particular relates to a combined connector end and a preparation method thereof. Background technique [0002] Underground excavation and transportation equipment mainly include scraper conveyors, bridge loaders and belt conveyors. The scraper conveyor is the key equipment in the coal mine transportation process. It can not only transport coal, but also provide a fulcrum for the transportation track and hydraulic support of the coal mining machine. It can be seen that the stability, safety and reliability of the scraper conveyor are closely related to the stable production of coal. [0003] In recent decades, with the continuous popularization of mechanization, coal mining technology and mechanical equipment have developed rapidly. In order to meet the needs of the market, relevant research institutes in my country have cooperated with major coal machinery manufa...
