Description
Technical Field
The utility model belongs to the technical field of hydraulic support, concretely relates to stop device is passed to thin seam hydraulic support.
Background
The hydraulic support for fully mechanized mining is generally used for thin coal seam fully mechanized mining working faces, the rear end of a push rod is upwarped in the normal pushing, sliding and frame moving processes, and when the push rod passes through a bridge at the front end of a base, an ear plate groove of a mounting and pushing jack is deformed under the influence of bridge passing acting force, and a press block is difficult to take out. Meanwhile, as the structure of the thin seam is compact, the hydraulic rubber pipe is fully distributed in the base, and the rubber pipe can be damaged to a certain extent when the rear end of the push rod is tilted upwards, people are always seeking a method for preventing the rear side from tilting upwards in the pushing process.
SUMMERY OF THE UTILITY MODEL
The utility model provides a stop device is passed to thin seam hydraulic support can ensure that the push rod is according to fixed orbit parallel translation, prevents that the push rod rear end from upwarping.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a low seam hydraulic support passes stop device, includes the base, is equipped with pusher jack in the base, and pusher jack bottom is equipped with the push rod, and base right side top relative position is equipped with curved apron, and curved apron bottom surface right side relative position is equipped with vertical decurrent right gusset, and the fixed apron that is equipped with the slope and arranges in right gusset bottom surface, apron left side are higher than the right side, and apron bottom surface left side relative position is equipped with vertical decurrent left gusset of arranging, and left gusset bottom surface is equipped with the limiting plate.
Further, the limiting plate is parallel to the bottom surface of the base.
Furthermore, the top surface of the cover plate is provided with a notch for facilitating the detachment of the pushing jack and the push rod connecting pin shaft, and the top surface of the cover plate is provided with a hoisting hole.
Furthermore, the top surface of the bent cover plate is provided with a hoisting hole.
Furthermore, the position of the limiting plate corresponds to the telescopic track of the pushing jack.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model has simple structure, easy manufacture and processing and low cost; utilize the structure that the hydraulic support in thin coal seam passed, the inboard design a hydraulic support in thin coal seam passes stop device in two interior owner muscle of base, increase limiting plate and left gusset to ensure that the push rod is according to fixed orbit parallel translation, prevent that the push rod rear end from upwarping.

Detailed Description
Example (b): as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the base comprises a base 1, a pushing jack 2 is arranged in the base 1, a push rod 3 is arranged at the bottom of the pushing jack 2, a bent cover plate 6 is arranged at the relative position of the top of the right side of the base 1, a right rib plate 8 which is vertically downward is arranged at the relative position of the right side of the bottom surface of the bent cover plate 6, a cover plate 5 which is obliquely arranged is fixedly arranged at the bottom surface of the right rib plate 8, the left side of the cover plate 5 is higher than the right side, a left rib plate 7 which is vertically downward arranged is arranged at the relative position of the left side of the bottom surface of the cover plate 5, and a limiting plate 4 is arranged at the bottom surface of the left rib plate 7. The limiting plate 4 is parallel to the bottom surface of the base 1, the top surface of the cover plate 5 is provided with a notch which is convenient for the pushing jack and the push rod connecting pin shaft to be detached, the top surface of the cover plate 5 is provided with a hoisting hole, the top surface of the bent cover plate 6 is provided with a hoisting hole, and the position of the limiting plate 4 corresponds to the telescopic track of the pushing jack 2.
The working process is as follows: when the lifting jack is used, the limiting plate 4 and the left rib plate 7 limit the up-and-down movement of the left lug plate and the right lug plate at the rear end of the push rod to a certain extent along with the extension and retraction of the lifting jack so as to ensure that the push rod moves parallelly according to a fixed track; the utility model discloses simple structure, convenient to use, the effectual thin seam hydraulic support advancing mechanism that has prevented floats, upwarps the problem.
