Abstract
The utility model discloses a hydraulic support and a traction device thereof, wherein the traction device comprises a rod body and front and rear connecting seats, the rod body adopts a long and narrow box body structure formed by upper and lower cover plates and side plates, a middle rib plate is arranged vertically between the upper and lower cover plates, and a plurality of supporting rib plates are arranged transversely thereon. The front connecting seat adopts a sheathing structure, and the connecting tab of the rear connecting seat adopts an arc-shaped curved surface. Under the condition that big alternating force action is met, the weight and the cross section of a push rod are reduced, so as to meet the requirements of structural arrangement and float coal discharging, and increase the oscillating adaptability after the rear part of the traction device is connected with the piston rod of the traction hoisting jack, which avoids the traction hoisting jack from being damaged inusing. The utility model is suitable for various types of pit hydraulic supports.
Description
Technical field
The utility model relates to suspension device under a kind of mine, especially relates to a kind of hydraulic support and push unit thereof.
Background technology
Pusher rod is a main stressed member of hydraulic support, be used to pass scratch board conveyor and draw and move support, simultaneously with lift end jack and cooperate the realization support to lift end function, pusher rod is not only born pulling force but also bear pressure and lateral force like this, require the design strength of pusher rod high as much as possible, improve push rod tensile strength and flexural strength, to guarantee it enough big safety factor is arranged, to reach instructions for use; Simultaneously, owing to be subjected to the requirement of structural configuration and row's float coal, pusher rod reduces its sectional area as far as possible when can bear very big alternating force effect.
There is following shortcoming at least in pusher rod of the prior art:
Sectional area is big, intensity is lower.
The utility model content
The purpose of this utility model provides hydraulic support and the push unit thereof that a kind of sectional area is less and intensity is higher.
The purpose of this utility model is achieved through the following technical solutions:
The push unit of hydraulic support of the present utility model comprises the body of rod and preceding Connection Block that is separately positioned on described body of rod two ends and back Connection Block, and the described body of rod is formed long and narrow body structure by upper cover plate, lower cover and two blocks of side plates.
Hydraulic support of the present utility model, this hydraulic support comprises above-mentioned push unit.
The technical scheme that provides by above-mentioned the utility model as can be seen, hydraulic support described in the utility model and push unit thereof are because the body of rod of push unit is formed long and narrow body structure by upper cover plate, lower cover and two blocks of side plates.Sectional area is less and intensity is higher.
Description of drawings
Fig. 1 is the facade structures schematic diagram of push unit of the present utility model;
Fig. 2 is the plan structure schematic diagram of push unit of the present utility model.
The specific embodiment
The push unit of hydraulic support of the present utility model, its preferable specific embodiment as shown in Figure 1 and Figure 2, comprise the body of rod and preceding Connection Block 1 that is separately positioned on body of rod two ends and back Connection Block 2, the body of rod is formed long and narrow body structure by upper cover plate 3, lower cover 4 and two blocks of side plates 5,6.Main muscle 8 in being vertically arranged with in the casing, in main muscle 8 and upper cover plate 3 and lower cover 4 vertical settings.Laterally be provided with a plurality of bearing ribs 7 in the casing, bearing rib 7 and upper cover plate 3, lower cover 4, in main muscle 8 and two blocks of side plates 5,6 fixedly connected respectively.This structure has significantly reduced the weight of push unit when satisfying big alternating force effect, and its cross section can be reduced as far as possible, satisfies the requirement of structural configuration and row's float coal.
Preceding Connection Block 1 is the wrapper sheet structure; The engaging lug place of back Connection Block 2 is an arcuate structure.
Hydraulic support of the present utility model, its preferable specific embodiment is that this hydraulic support comprises above-mentioned push unit.
Hydraulic support comprises base, is connected by passing jack between the back Connection Block 2 of push unit and the base, and specifically afterwards the engaging lug of Connection Block 2 can be hinged with the piston rod of described passing jack, the setting that recedes of its hinge; The preceding Connection Block 1 of push unit is hinged with scratch board conveyor.
In the utility model, preceding Connection Block 1 is the wrapper sheet structure, and the connector of scratch board conveyor can be swung, and prevents rigid fractureing; The engaging lug place of back Connection Block 2 is an arc-shaped curved surface, has increased engaging lug and the swing compliance of passing after jack piston rod is connected, and the hinge of back Connection Block is obliquely installed, and the pulling force that effectively distributed is avoided passing jack and in use is damaged.
The above; it only is the preferable specific embodiment of the utility model; 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 variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
