Description
TECHNICAL FIELD
[0001] The utility model relates to hydraulic support technical field, specifically speaking, relate to a truss structure connecting rod for hydraulic support. BACKGROUND
[0002] China's coal resources are rich, widely distributed, is the world's first coal producing country, the amount of hydraulic support in coal mine fully mechanized equipment is very much, hydraulic support four connecting rod structure is widely used. Figures 1-3 As shown, the conventional hydraulic support connecting rod is mainly by main reinforcement plate 1, bending cover plate 2 and cross partition 3 are sequentially welded, its structural form is box beam structure, when working, the hinged force is transmitted through the plate, thereby realizing the function. The main shortcomings of this kind of hydraulic support connecting rod are:
[0003] (1) heavy weight: main reinforcement plate 1, bending cover plate 2 and cross partition 3 are thick plate parts;
[0004] (2) raw material specification is many: the thickness of main reinforcement plate 1, bending cover plate 2 and cross partition 3 is different;
[0005] (3) manufacturing procedure is many: the traditional hydraulic connecting rod manufacturing procedure is mainly blanking→ first level assembly→ welding→ second level assembly→ welding;
[0006] (4) low transmission efficiency.
[0007] Therefore, the manufacturing cost of the conventional hydraulic support connecting rod is high, heavy, inconvenient transportation and downhole. However, there is no optimization design for the hydraulic support connecting rod at present.
[0008] In order to solve the above problems, people have been seeking an ideal technical solution. SUMMARY
[0009] The utility model discloses a truss structure connecting rod for hydraulic support, which has the advantages of higher transmission efficiency, simple structure, easy manufacturing, low manufacturing cost, light weight, convenient transportation and downhole, and wide market prospect compared with the ordinary connecting rod.
[0010] In order to achieve the above object, the utility model adopts the technical scheme of a truss structure connecting rod for hydraulic support, which comprises a truss rod and two hinge cylinders, the two hinge cylinders are arranged in parallel and are respectively welded and fixed at two ends of the truss rod, and the center line of the hinge cylinder is perpendicular to the length direction of the truss rod.
[0011] Based on the above, the truss rod is composed of round steel.
[0012] Based on the above, the outer circumference of the connection between the hinge cylinder and the truss rod is integrally formed with a circular ring convex rib.
[0013] The hydraulic support connecting rod of the utility model has the advantages of substantial features and progress compared with the prior art, specifically, the box beam structure of the conventional hydraulic support connecting rod is optimized to a truss structure, the truss structure mainly consists of truss bars and hinged tubes welded at both ends of the truss bars, the truss structure has higher force transmission efficiency than the box beam structure, so that the structure can be simplified, the weight can be greatly reduced, the weight of the hydraulic support connecting rod can be reduced by more than 30%, the truss bars are spliced and welded in a few processes and have low splicing and welding requirements, the truss bars are easy to manufacture, the manufacturing cost is greatly reduced, transportation and well drilling are facilitated, and the utility model has a wide market prospect.

[0021] The technical scheme of the utility model will be described in further detail below through specific embodiments.
[0022] As Figures 4-6 shown in the drawing, a truss structure connecting rod for a hydraulic support comprises a truss bar 4 and two hinged tubes 5, the two hinged tubes 5 are arranged in parallel and are respectively welded and fixed at both ends of the truss bar 4, and the center line of the hinged tube 5 is perpendicular to the length direction of the truss bar 4.
[0023] The truss bar 4 of the embodiment is composed of round steel welding.
[0024] The connection part of the hinged tube 5 and the truss bar 4 is integrally formed with a circular ring convex rib 6 on the outer circumference. The circular ring convex rib 6 enhances the structural strength of the hinged tube 5.
[0025] When the truss structure connecting rod of the embodiment works, the hinged force is transmitted through the truss member 4, so as to realize the function, and because the truss member 4 has higher force transmission efficiency than the box beam structure, the structure can be simplified and the weight is reduced, the weight of the truss structure connecting rod of the embodiment is 2 / 3 of the ordinary connecting rod, and the truss member 4 has less tailor-welding process, low tailor-welding requirement, is easy to manufacture, and has low manufacturing cost. The truss structure connecting rod of the embodiment has light overall weight, is convenient for transportation and downhole, and has wide market prospect.
