Abstract
The utility model relates to a novel deformation-resistant mine I-beam bracket. The I-beam bracket comprises a supporting frame adopting a trapezoid frame without a lower beam; a horizontal top beam is arranged at the top of the frame; two ends of the top beam are fixedly connected with supporting legs as well as baseplates respectively; the supporting legs and the baseplates are supported on the ground and are clung to an inner side surface of a laneway in a supported manner; a vertical connecting rod and a spherical hinging structure are fixedly connected with the middle of the top beam, and vertically arranged below the middle of the top beam; inclined connecting rods are symmetrically arranged among the supporting legs and the top beam; and two ends of each inclined connecting rod are hinged with an inner side of a corresponding supporting leg and the spherical hinging structure respectively. The novel deformation-resistant mine I-beam bracket has the advantages of simple structure, higher bending deformation resistant capability, higher bearing capacity, and higher stability, and can effectively bear and disperse extrusion of the top plate and two sides of the laneway, so as to prevent the laneway from deforming.
Description
Technical field
The utility model relates to a kind of colliery tunnel support device, and especially a kind of deep mining stope drift active workings suspension device is a novel anti distortion mining i beam support.
Background technology
Along with coal mining develops to the deep, it is strong that mine engenders that the ore deposit pressure manifests, and roadway deformation destroys serious, is having a strong impact on the normal propelling and the air-conditioning requirement of coal-face, and coal resources safety and high efficiency under the deep-well condition is had serious restriction.
Both at home and abroad expert and field technician generally believe that the supporting of deep mining stope drift active workings adopts the spray of anchor net and shape steel bracket combined supporting or the spray of anchor net, anchor cable, shape steel bracket combined supporting the most effective.And for China most of stopes of coal mines tunnel, shape steel bracket is generally used the I-shaped steel bracket.
But The field finds, the mining i beam stent applications in the supporting of deep mining stope drift active workings, the back timber deflection deformation of often sinking, even fracture, and the canopy leg occurs bending and deformation to the inside, finally makes the support global failure.This problem is the critical problem of puzzlement deep mining stope drift active workings supporting always.Therefore, the mining i beam support is improved, increase its bending resistance deformation ability, it is significant, and use has a high potential.
The utility model content
In order to solve the problem that the bending distortion in use takes place the mining i beam support easily, the utility model proposes a kind of novel anti distortion mining i beam support, this supporting structure is simple, has stronger bending resistance deformability, supporting capacity and stability, the extruding that can effectively bear and disperse back and two to help reaches the purpose that stops roadway deformation.
The technical scheme that its technical problem that solves the utility model adopts is: novel anti distortion mining i beam support comprises supporting leg, back timber, vertical connecting rod, globular hinge structure, diagonal control arm, base plate, this i iron support has the support frame of a trapezoidal following few horizontal stroke, a horizontal back timber is arranged at the top of this framework, stably supports the end face in tunnel; The two ends of this back timber are fixedly connected with support respectively and are adjacent to the supporting leg and the base plate of support on the ground and with the tunnel medial surface; The intermediate vertical of this back timber is fixedly connected with vertical connecting rod and globular hinge structure downwards; Be arranged with diagonal control arm between this supporting leg and the back timber, the two ends of this diagonal control arm are hinged with an inboard leg and globular hinge structure respectively.
The beneficial effects of the utility model are: this novel anti distortion mining i beam supporting structure is simple, has stronger bending resistance deformability, supporting capacity and stability, the extruding that can effectively bear and disperse back and two to help reaches the purpose that stops roadway deformation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the example structure schematic diagram of this novel anti distortion mining i beam support.
Among the figure, 1. supporting leg, 2. back timber, 3. vertical connecting rod, 4. globular hinge structure, 5. diagonal control arm, 6. base plate.
The specific embodiment
In the accompanying drawings, novel anti distortion mining i beam support comprises supporting leg 1, back timber 2, vertical connecting rod 3, globular hinge structure 4, diagonal control arm 5, base plate 6, this i iron support has the support frame of a trapezoidal following few horizontal stroke, a horizontal back timber 2 is arranged at the top of this framework, stably supports the end face in tunnel; The two ends of this back timber 2 are fixedly connected with support respectively and are adjacent to the supporting leg 1 and the base plate 6 of support on the ground and with the tunnel medial surface; The intermediate vertical of this back timber 2 is fixedly connected with vertical connecting rod 3 and globular hinge structure 4 downwards; Be arranged with diagonal control arm 5 between this supporting leg 1 and the back timber 2, the two ends of this diagonal control arm 5 are hinged with supporting leg 1 inboard and globular hinge structure 4 respectively.
When roof weighting, back timber 2 is stressed, and the power part that top board acts on the back timber 2 directly is delivered to base plate 6 by supporting leg 1, and a part is delivered to supporting leg 1 by vertical connecting rod 3 and diagonal control arm 5, and supporting leg 1 extruding tunnel two is helped, and suppresses two distortion of helping; Two help the power of squeezing action on supporting leg to pass to back timber 2 by vertical connecting rod 3 and diagonal control arm 5 again simultaneously, the sinking of opposing top board.No matter stressed still supporting leg 1 is stressed for back timber 2, all is to help the mutual opposing of the two finally to reach the purpose that stops roadway deformation by top board, two, has solved that the common back timber of deep mining stope drift active workings mining i beam support fractures, the difficult problem of canopy leg distortion.
