Abstract
The utility model discloses a special protecting hood for a telescopic upright post for a vertical hydraulic bracket, which comprises a soft hood body provided with support ribs. The hood body is a stepped straight drum body matching with the outer diameters of all stages of cylinder jackets of the telescopic upright post, and annular connecting belts are horizontally arranged on the hood body, corresponding to the joints of every two stages of cylinder jackets. When in use, the protecting hood is sleeved on the telescopic upright post for the hydraulic bracket; the annular connecting belts on the hood body are correspondingly mounted on the joint surfaces of every two cylinder jackets; and when an oil cylinder drives the telescopic upright post to work, the straight drum body outside the cylinder jackets stretches and retracts naturally along with the upright post without causing rigid extrusion, thus prolonging the service life of the protecting hood. Since the middle part of the telescopic upright post works frequently, a support rib can be added on the hood body corresponding to the middle part of the telescopic upright post. For facilitating the installation and replacement of the protecting hood on site, a mounting hole is arranged at the side face of the hood body and a connected buckle is arranged on the mounting hole.
Description
Technical field
The utility model relates to a kind of protective cover, especially relates to three-dimensional hydraulic support telescopic column special protection cover used under a kind of coal mine.
Background technology
Hydraulic support be coal mine operation the equipment that must use, difference according to head-room, the telescopic column of hydraulic oil cylinder driving can be adjusted the supporting height of hydraulic support, because the particularity of coal mine operation, coal dust can enter in the cylinder sleeve of telescopic column, shortened the application life of hydraulic support, and the protective cover that is sleeved on outside it just can stop that dust enters in the cylinder sleeve of telescopic column.Existing protective cover is the gentle matter cover body made from fire-retardant, antistatic lining of the folded formula in plane, the cover body cloth at two-stage cylinder sleeve link position place adopts evenly folded, form transition, it after the expansion up-narrow and down-wide ladder plane structure, with its protective cover shroud after on the telescopic column, along with the flexible work of telescopic column, not only the telescopicing performance at folded place is bad, also because often extruding causes the protective cover breakage.
The utility model content
The purpose of this utility model is to provide the three-dimensional hydraulic support telescopic column special protection cover of the good and long service life of a kind of telescopicing performance.
For achieving the above object, the utility model can be taked following technical proposals:
Three-dimensional hydraulic support telescopic column special protection cover described in the utility model, comprise the flexible cover body that has brace rod, described cover body is the straight barrel structure of stairstepping that adapts with telescopic column cylinder sleeve external diameters at different levels, has been horizontally disposed with annular connecting band on the cover body corresponding to two-stage cylinder sleeve binding site.
For making things convenient for the installation of protective cover, the side of described cover body offers installing port, and it is provided with junction button.
Advantage of the present utility model is that cover body is the straight barrel structure of stairstepping that adapts with telescopic column cylinder sleeve external diameters at different levels, be horizontally disposed with annular connecting band on the cover body corresponding to two-stage cylinder sleeve binding site, during use, it is sleeved on the hydraulic support telescopic column, the annular connecting band correspondence of on the cover body each is placed on the bonding surface of two-stage cylinder sleeve, during the work of hydraulic oil cylinder driving telescopic column, straight tube cover body outside the cylinder sleeve is along with column stretches naturally, shrinks, can not produce rigid extruding, prolong the application life of protective cover.Because the work of the middle part of telescopic column is comparatively frequent, can add one brace rod on the corresponding cover body.Install and change for the scene that makes things convenient for protective cover, the side of described cover body offers installing port, and it is provided with junction button.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, three-dimensional hydraulic support telescopic column special protection cover described in the utility model, comprise the flexible cover body 2 that has brace rod 1, described cover body 2 is the straight barrel structure of stairstepping that adapts with telescopic column cylinder sleeve external diameters at different levels, has been horizontally disposed with annular connecting band 3 on the cover body 2 corresponding to two-stage cylinder sleeve binding site; The side of described cover body 2 offers installing port 4, and it is provided with junction button 5.
Claims (2)
1, a kind of three-dimensional hydraulic support telescopic column special protection cover, comprise the flexible cover body (2) that has brace rod (1), it is characterized in that: described cover body (2) is the straight barrel structure of stairstepping that adapts with telescopic column cylinder sleeve external diameters at different levels, has been horizontally disposed with annular connecting band (3) on the cover body (2) corresponding to two-stage cylinder sleeve binding site.
