Abstract
The utility model discloses a kind of non-body structure connecting rod, comprise and superposing and many main muscle be welded and fixed together, after many main muscle are welded and fixed, be respectively equipped with hinge hole at two ends.The material of main muscle is consistent with the material of the base of hydraulic support, back timber and caving shield.Structure is simple, economic and practical, reasonable stress, intensity are high.
Description
Technical field
The utility model relates to a kind of coal-mine hydraulic support connecting rod, particularly relates to a kind of non-body structure connecting rod.
Background technology
At present, adopt the hydraulic support of quadric chain, front and rear connecting rods is welding body structure.The factor affecting connecting rod strength comprises: the physical dimension of the strength of materials and casing.
As shown in Figure 1 a, 1 b, the casing that it is welded by cover plate, main muscle (assembly), gusset forms bar linkage structure of the prior art.
Due to the diversity of different mining areas work plane, in some low mining height hydraulic support design, body structure connecting rod of the prior art, can not meet required design strength when using conventional high strength steel plate material, according to special rolling-mill section, procurement cycle is long, and somewhat expensive, be unfavorable for producing.
Utility model content
The purpose of this utility model is to provide the non-body structure connecting rod that a kind of structure is simple, economic and practical, reasonable stress, intensity are high.
The purpose of this utility model is achieved through the following technical solutions:
Non-body structure connecting rod of the present utility model, comprises and superposing and many main muscle be welded and fixed together, be respectively equipped with hinge hole after many main muscle are welded and fixed at two ends.
The technical scheme provided as can be seen from above-mentioned the utility model, the non-body structure connecting rod that the utility model embodiment provides, superpose and many main muscle be welded and fixed together owing to comprising, structure is simple, economic and practical, reasonable stress, intensity are high.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
Non-body structure connecting rod of the present utility model, its preferably detailed description of the invention be:
Comprise and superposing and many main muscle be welded and fixed together, after many main muscle are welded and fixed, be respectively equipped with hinge hole at two ends.
Comprise the main muscle of odd number bar.Preferably include 3 main muscle.
The thickness of described many main muscle is equal.
The material of described main muscle is consistent with the material of the base of hydraulic support, back timber and caving shield.
Non-body structure connecting rod of the present utility model, many on it main muscle superpositions are welded to form non-body structure, and structure is simple, economic and practical, reasonable stress, intensity are high.
The structure of many main muscle superpositions, strengthens greatly compared with the intensity of body structure on the one hand, can eliminate stress on the other hand concentrated, adopts the superposition of odd number bar main muscle can balanced connecting rod both sides stressed, makes its stress more reasonable.
Specific embodiment:
As shown in Fig. 2 a, 2b, 2c, only superposed by many main muscle of equal thickness and be welded.
Other main components bases of main muscle material and hydraulic support, back timber, caving shield main material are consistent.
The bar linkage structure of this kind of structure is simple, and material buying easily, can effectively reduce fabricating cost and manufacturing cycle.Try out at supports such as Y98 at present.Through inspection, service condition is good.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
