Abstract
The utility model relates to a kind of rotary type hydraulic support control valve blocking device.Described blocking device, comprise hydraulic chock running valve group, hydraulic chock running valve group two ends are provided with front apron and backboard, front apron top margin is connected with support plate base, backboard top margin is connected with postive stop baffle base, support plate is rotationally connected by bolt and swivel plate, and swivel plate end is flexibly connected with block ring.The utility model structure is simple, and convenient operation, is transformed to lateral rotation by spinning upside down of blocking mechanism in prior art, and locking operation needs space little, can not limit the use of blocking device, improve the safety of production operation because the height of support is too low.
Description
Technical field
The utility model relates to a kind of rotary type hydraulic support control valve blocking device.
Background technology
At present, hydraulic chock running valve control support crane, move frame, pushing and sliding, balance adjustment, wall supporting, the various actions such as front-axle beam is flexible, side is protected, reliability and the safety of its work are extremely important.In real work, because control valve is generally positioned at above base, its hand longitudinally arranged is being exposed on walkway narrow between the large column of hydraulic support and scraper conveyor cable trough, particularly the heavy cutter of coal-winning machine is to head coal cutting, after hydraulic moving stand with the pushing and sliding of coal-winning machine demobilization cutter before, pedestrian space between hydraulic support and drag conveyor is especially narrow, pedestrian very easily scratching control valve hand and make hydraulic support misoperation, cause top board or casualty accident.Support operating valve blocking device of the prior art is for spinning upside down mechanism, and this mechanism cannot can overturn by return after hydraulic support bearing height step-down, causes blocking device normally to use, thus threatens the safety of production operation.
Utility model content
the purpose of this utility model is to provide a kind of rotary type hydraulic support control valve blocking device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Rotary type hydraulic support control valve blocking device, comprise hydraulic chock running valve group, described hydraulic chock running valve group two ends are provided with front apron and backboard, front apron top margin is connected with support plate base, backboard top margin is connected with postive stop baffle base, support plate is rotationally connected by bolt and swivel plate, and swivel plate end is flexibly connected with block ring.
Preferably, described support plate is provided with cambered way, and swivel plate is installed with slide block, and slide block is flexibly connected with cambered way.
Preferably, described block ring is composed of a fixed connection, in class ellipse shape by two straight-bars and two single u-shaped bars.
Preferably, the length of described block ring is identical with the spacing of forward and backward baffle plate.
Preferably, two U-shaped ends of described block ring, one end is connected with swivel plate end by sleeve, and the other end is flexibly connected with postive stop baffle.
During work, swivel plate is rotated around bolt, due to the position-limiting action of cambered way on slide block and support plate, the circumference of swivel plate is rotated and is carried out in same plane, there will not be the phenomenon moved up and down, when swivel plate go to block ring be positioned at the top of hydraulic chock running valve group time, block ring is rotated around sleeve, realizing block ring snaps on postive stop baffle, and the movement of two straight-bar restriction action bars of block ring, realizes the locking of hydraulic support operating valve group; When staff needs operation hydraulic support operating valve group, the unblock of hydraulic support operating valve group can be realized by said process negative actuation.
The utility model compared with prior art, tool has the following advantages: structure is simple, convenient operation, spinning upside down of blocking mechanism in prior art is transformed to lateral rotation, locking operation needs space little, the use of blocking device can not be limited because the height of support is too low, improve the safety of production operation.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, rotary type hydraulic support control valve blocking device, comprise hydraulic chock running valve group, described hydraulic chock running valve group two ends are provided with front apron 1 and backboard 11, front apron 1 top margin is connected with support plate 3 base, backboard 11 top margin is connected with postive stop baffle 10 base, support plate 3 is rotationally connected by bolt 6 and swivel plate 4, support plate 3 is provided with cambered way 7, swivel plate 4 is installed with slide block 5, slide block 5 is flexibly connected with cambered way 7, swivel plate 4 end is connected with block ring 9 by sleeve 8, block ring 9 is composed of a fixed connection by two straight-bars and two single u-shaped bars, in class ellipse shape, two U-shaped ends of block ring 9, one end is connected with swivel plate 4 end by sleeve 8, the other end is flexibly connected with postive stop baffle 10, the length of block ring 9 and front apron 1, the spacing of backboard 11 is identical.
During work, swivel plate 4 is rotated around bolt 6, due to slide block 5 and the position-limiting action of cambered way 7 on support plate 3, the circumference of swivel plate 4 is rotated and is carried out in same plane, there will not be the phenomenon moved up and down, when swivel plate 4 go to block ring 9 be positioned at the top of hydraulic chock running valve group time, block ring 9 is rotated around sleeve 8, realizing block ring 9 snaps on postive stop baffle 10, and the movement of two straight-bar restriction action bars 2 of block ring 9, realizes the locking of hydraulic support operating valve group; When staff needs operation hydraulic support operating valve group, the unblock of hydraulic support operating valve group can be realized by said process negative actuation.
