Abstract
The utility model relates to the field of a hydraulic bracket, in particular to a leak-proof waste rock structure of the hydraulic bracket, aiming at solving the problems that the waste rock can fall off from a large mining height hydraulic bracket to injure persons, and the like, and protecting the security of the walkers and the operation space. The structure comprises a top beam, a top beam side protecting board, a shielding beam and a soft rubber board, wherein the top beam, the top beam side protecting board and the shielding beam are articulated with each other into a whole through hinge pins; and the soft rubber board is fixed on a top board of the shielding beam at the articulation positions of the hinge pins through screw nails and super glue. By being applied to the articulation positions among the top beam, the top beam side protecting board and the shielding beam of the hydraulic bracket, the structure has the maximum advantages of being capable of effectively preventing the waste rock from being swarmed from a hinged shaft to fall off to hurt persons, and protecting the security of the walkers and the operation space.
Description
Technical field
The utility model relates to the colliery and uses the hydraulic support field, especially relates to a kind of hydraulic support leakproof cash structure.
Background technology
At present, the hydraulic support that use in the colliery, its back timber and back timber side guard board and caving shield hinged place just in time be in the walkway directly over, if there is gangue to fall, be easy to hurt sb.'s feelings, especially big mining height hydraulic support, supporting height is high more, and the spoil under the high-altitude is weighed down is just big more to operating personnel's danger.So big mining height hydraulic support is hurted sb.'s feelings in order to prevent that spoil from falling, guarantee that the safety of pedestrian and operating space is an important topic of its design.
The utility model content
The purpose of this utility model is to provide a kind of hydraulic support leakproof cash structure, solves big mining height hydraulic support spoil and falls and hurt sb.'s feelings, and guarantees the security problems of pedestrian and operating space.
The technical solution of the utility model is:
A kind of hydraulic support leakproof cash structure comprises the back timber and back timber side guard board and the caving shield that are articulated as one by bearing pin, adopts screw that soft rubber pad is arranged on the top board that is positioned at bearing pin hinged place caving shield.
Described hydraulic support leakproof cash structure, the contact surface of soft rubber pad and top board adopts gluing connecing.
Described hydraulic support leakproof cash structure, soft rubber pad is positioned at the bottom of top board.
The beneficial effects of the utility model are:
1, the utility model hydraulic support leakproof cash structure is being positioned on the caving shield top board of bearing pin hinged place with screw and the fixing soft rubber pad of seccotine; During work, back timber and back timber side guard board and caving shield hinged place are covered, avoid gangue to enter.
2, after the utility model adopts hydraulic support leakproof cash structure, can stop gangue to pour in the fall injury operating personnel effectively, guarantee the safety of pedestrian and action space from the bearing pin hinged place.
Description of drawings
Fig. 1 is the utility model hydraulic support leakproof cash structural representation.
Fig. 2 is the I portion enlarged drawing of the utility model hydraulic support leakproof cash structure chart 1.
Fig. 3 is the schematic diagram of the utility model hydraulic support leakproof cash structure on caving shield.
Among the figure, 1, bearing pin; 2, back timber and back timber side guard board; 3, caving shield; 4, screw; 5, soft rubber pad; 6 top boards.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further:
As Figure 1-3, the utility model hydraulic support leakproof cash structure, comprise the back timber and back timber side guard board 2 and the caving shield 3 that are articulated as one by bearing pin 1, be fixed with soft rubber pad 5 with screw 4 on the top board 6 that is positioned at bearing pin 1 hinged place caving shield 3, it is bonding that the contact surface of soft rubber pad 5 and top board 6 adopts seccotine simultaneously.Wherein, soft rubber pad 5 is positioned at the bottom of top board 6.
