Abstract

The utility model provides a kind of coal mine hydraulic supporting side and pushes away jack, including the cylinder barrel being located in top beam sleeve, piston rod is equipped in cylinder barrel, piston rod is stretched out along cylinder barrel top, weld cylinder bottom in the bottom end of cylinder barrel, the weld seam of the affixed side guard plate of cylinder bottom, the cylinder bottom and cylinder barrel welding is between top beam sleeve and side guard plate.Distance set is equipped in the cylinder barrel, distance set is between cylinder bottom and piston rod.The bottom of the piston rod is between top beam sleeve and cylinder bottom and close to top beam sleeve.Compared with prior art, the cylinder barrel of the ingenious adjustment jack of the utility model and the weld seam of cylinder bottom, weld seam is set to avoid shearing stress point, increase the length that distance covers or increases piston rod in cylinder barrel, so that the motion range of side guard plate is constant, the cracking of cylinder bottom weld seam is effectively prevented, spoilage is reduced, reduces maintenance cost.

Description

A kind of coal mine hydraulic supporting side pushes away jack
Technical field
The utility model relates to technical field of coal mine equipment, and in particular to a kind of coal mine hydraulic supporting side pushes away jack.
Background technique
It is the common support device of coal mine operation that side, which pushes away jack,.On the hydraulic support of coal mine fully-mechanized mining working, side shield Device is important a component, pushes away jack by side to push the flexible of side guard plate, can effectively avoid falling between frame Cash.Existing side pushes away jack structure as shown in Fig. 2, cylinder bottom 2 is solid cylindrical shape, and cylinder bottom 2 is longer, and cylinder bottom 2 and cylinder barrel 3 weld It connects, weld seam 8 is equipped with piston rod 5 in one end of the close cylinder bottom 2 of top beam sleeve 4, cylinder barrel 3.When work, side pushes away jack position In the inside of top beam sleeve 4, cylinder bottom 2 is connect by fixed pin 7 with side guard plate 1 and is fixed, and pushes away the flexible of jack by side Side guard plate 1 is driven to be moved.But since the weld seam 8 that side pushes away jack is exactly in cutting for side guard plate 1 and top beam when working Receive force, not only to bear the axial force of liquid in jack, still suffers from the radial force passed over by side guard plate 1, And especially in the working face of breaking roof 6, so side pushes away jack and easily generates cylinder bottom weld cracking.
Summary of the invention
Cylinder bottom weld cracking is easily generated to solve the problems, such as that side pushes away jack in the prior art, the utility model provides one Kind coal mine hydraulic supporting side pushes away jack.
The purpose of this utility model is achieved in that
A kind of coal mine hydraulic supporting side pushes away jack, including the cylinder barrel 3 being located in top beam sleeve 4, is equipped with piston in cylinder barrel 3 Bar 5, piston rod 5 are stretched out along 3 top of cylinder barrel, and cylinder bottom 2, the affixed side guard plate 1 of cylinder bottom 2,2 He of cylinder bottom are welded in the bottom end of cylinder barrel 3 The weld seam 8 that cylinder barrel 3 welds is between top beam sleeve 4 and side guard plate 1.
Distance set 9 is equipped in the cylinder barrel 3, distance set 9 is between cylinder bottom 2 and piston rod 5.
The bottom of the piston rod 5 is between top beam sleeve 4 and cylinder bottom 2 and close to top beam sleeve 4.
The utility model has the advantages that compared with prior art, the cylinder barrel of the ingenious adjustment jack of the utility model and the weld seam of cylinder bottom make Weld seam avoids shearing stress point, increases the length that distance covers or increases piston rod in cylinder barrel, so that the motion range of side guard plate It is constant, the cracking of cylinder bottom weld seam is effectively prevented, spoilage is reduced, reduces maintenance cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the prior art.
Wherein, 1 is side guard plate；2 be cylinder bottom；3 be cylinder barrel；4 be top beam sleeve；5 be piston rod；6 be breaking roof；7 are Fixed pin；8 be weld seam；9 be distance set.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of coal mine hydraulic supporting side pushes away jack, including the cylinder barrel 3 being located in top beam sleeve 4, cylinder barrel 3 Interior to be equipped with piston rod 5, piston rod 5 is stretched out along 3 top of cylinder barrel, and cylinder bottom 2, the affixed side guard plate 1 of cylinder bottom 2, institute are welded in the bottom end of cylinder barrel 3 Weld seam 8 that cylinder bottom 2 and cylinder barrel 3 weld is stated positioned at top beam sleeve 4 and side guard plate 1 between, to avoid shearing stress point.Side pushes away very heavy The other structures on top are same as the prior art, and details are not described herein.
In order to keep the motion range of side guard plate 1 constant, distance set 9 is equipped in the cylinder barrel 3, distance set 9 is located at 2 He of cylinder bottom Between piston rod 5, distance set 9 is for limiting the movement of cylinder bottom 2.
When utility model works, cylinder barrel 3 does relative motion with piston rod 5, since cylinder barrel 3 and cylinder bottom 2 weld, cylinder bottom 2 It is fixedly connected with side guard plate 1 by fixed pin 7, cylinder bottom 2 will drive the movement of side guard plate 1 when moving, when cylinder bottom 2 continues to move to the right When cylinder bottom 2 will push distance set and 9 move to 5 direction of piston rod, when distance covers 9 contact piston bar 5, the blocking cylinder bottom 2 of piston rod 5 Continue to move with distance set 9, then side guard plate 1 also no longer moves, just side guard plate 1 moves to required position at this time.
Embodiment 2
A kind of coal mine hydraulic supporting side pushes away jack, including the cylinder barrel 3 being located in top beam sleeve 4, is equipped with piston in cylinder barrel 3 Bar 5, piston rod 5 are stretched out along 3 top of cylinder barrel, and cylinder bottom 2, the affixed side guard plate 1 of cylinder bottom 2,2 He of cylinder bottom are welded in the bottom end of cylinder barrel 3 The weld seam 8 that cylinder barrel 3 welds is between top beam sleeve 4 and side guard plate 1, to avoid shearing stress point.Side pushes away other of jack Structure is same as the prior art, and details are not described herein.
In order to keep the motion range of side guard plate 1 constant, the bottom of the piston rod 5 is between top beam sleeve 4 and cylinder bottom 2 And close to top beam sleeve 4, that is to say, that piston rod 5 compared with the existing technology, piston rod 5 of the invention are extended version.
When utility model works, cylinder barrel 3 does relative motion with piston rod 5, since cylinder barrel 3 and cylinder bottom 2 weld, cylinder bottom 2 It is fixedly connected with side guard plate 1 by fixed pin 7, cylinder bottom 2 will drive the movement of side guard plate 1 when moving, when cylinder bottom 2 continues to move to the right When, when cylinder bottom 2 can touch piston rod 5, piston rod 5 stops cylinder bottom 2 to continue to move at this time, then side guard plate 1 also no longer moves, Just side guard plate 1 moves to required position at this time.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as The protection scope of the utility model, these all will not influence the effect and patent practicability of the utility model implementation.
