Problems solved by technology

[0002] Drilling rig is one of the essential equipment in mine work, and when the drilling rig is working, the propulsion chain is an essential part. Now the connection of the propulsion chain of the drilling rig is directly staggered with double-hole fixing plates, and the connection is firm. Poor performance, without strengthening fixed points and lubricating points, easy to wear or fatigue fracture during use, causing the danger of falling, not only affecting normal production, reducing production efficiency, but also causing production safety accidents in severe cases

Embodiment Construction

[0016] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0017] Such as Figure 1-2 As shown, the coupling piece for the drilling rig propulsion chain of the present invention includes a coupling body 3, a central through hole 2 is arranged in the middle of the coupling body 3, and a first coupling through hole 1 and a second coupling through hole 1 are arranged symmetrically on both sides of the central through hole 2. Through hole 4, the distance between the center point of the first connecting through hole 1 and the second connecting through hole 4 and both ends of the connecting body 3 is 43.5 mm, and the distance between the center point of the first connecting through hole 1 and the center point of the second connecting through hole 4 is 43.5 mm. The distance between them is 82.5mm.

[0018] The diameter of the central through hole 2 is 16 mm, and the diameters of the first connecting through hole 1 and the sec...

Abstract

The invention relates to a connector for a drilling machine propelling chain, and the drilling machine propelling chain, and belongs to the field of mining mechanical equipment. The connector for thedrilling machine propelling chain comprises a connector body, wherein a center through hole is formed in the center of the connector body; a first connection through hole and a second connection through hole are symmetrically formed in two sides of the center through hole; the distances between the center points of the first connection through hole and the second connection through hole and two ends of the connector body are 43.5mm; and the distance between the center point of the first connection through hole and the center point of the second connection through hole is 82.5mm. The connectorfor the drilling machine propelling chain provided by the invention is simple in structure, reasonable in design, convenient to use, capable of reducing the wear, protecting the safe production, improving the production efficiency and reducing the overhaul and maintenance cost, and high in practicability.

Description

technical field [0001] The invention relates to a coupling piece for a drilling rig propelling chain and the drilling rig propelling chain, belonging to the field of mining machinery and equipment. Background technique [0002] Drilling rig is one of the essential equipment in mine work, and when the drilling rig is working, the propulsion chain is an essential part. Now the connection of the propulsion chain of the drilling rig is directly staggered with double-hole fixing plates, and the connection is firm. Poor performance, without strengthening fixed points and lubricating points, it is easy to wear or fatigue fracture during use, causing the danger of falling, which not only affects normal production, reduces production efficiency, but also causes production safety accidents in severe cases. Contents of the invention [0003] According to the deficiencies in the above prior art, the problem to be solved by the present invention is: provide a simple structure, reasonab...
