Description
Technical Field
The utility model relates to an equipment auxiliary device for the colliery, concretely relates to dark inclined shaft belt safety backstop.
Background
When a belt blind inclined shaft appears during coal mine tunneling, the blind inclined shaft generally has a certain gradient, a belt conveyor needs to be arranged to convey waste rocks generated during tunneling in the whole construction process, the belt can be torn off and thrown up during the belt conveying process due to the large volume and the large specific gravity of the waste rocks, and a large piece of the waste rocks falls and slides down; or the stones and the subsequent coal blocks can slide downwards due to gravity, so that the accidents of hurting people or the damage to equipment can occur.
Disclosure of Invention
The utility model provides an among the belt transportation process of solving colliery hidden inclined shaft, exist because stone and follow-up coal cinder can lead to the gliding because of gravity reason to the technical problem who hurts people's accident or damage equipment takes place, provides a hidden inclined shaft belt safety holdback, can guarantee that stone and follow-up coal cinder that produce can not lead to gliding because of gravity reason and cause the condition appearance that personnel are injured or equipment damages.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: a belt safety backstop for a blind inclined shaft comprises two tripods which are arranged in parallel, wherein each tripod comprises two support rods which are respectively a first support rod and a second support rod, an included angle between the two support rods is consistent with the gradient of the blind inclined shaft, the first support rod is vertically arranged, and the tops of the two support rods are fixedly connected with a top plate together; a supporting beam is rotatably connected to the top plate, a plurality of supporting plates are fixedly sleeved on the supporting beam in a fixing way, one end of each supporting plate is fixedly connected to the supporting beam, and the other end of each supporting plate can freely rotate along with the supporting beam; the upper ends of the two first supporting rods are jointly fixed with a stop beam, and the free ends of the supporting plates abut against the stop beam.
The working principle is as follows: two tripods are located the belt both sides respectively, and the tripod is perpendicular with the belt, and the roof is parallel with the belt, and the backup pad can guarantee only along with belt upward movement and can not appear gliding phenomenon when going upward the belt when fortune stone, leans on tail department design stop beam in the backup pad, guarantees that the backstop backup pad can only move upwards, can not move downwards. The generated stone blocks and the subsequent coal blocks can be ensured not to slide down due to gravity.
Compared with the prior art the utility model discloses following beneficial effect has:
the utility model discloses the stone that belt safety backstop can effectual assurance produce and follow-up coal cinder can not lead to the gliding because of the gravity reason and cause the condition of personnel's injury or equipment damage to appear. The belt safety backstop has the advantages of simple structure and low manufacturing cost, and the split design can ensure that a certain part of the backstop can be quickly and conveniently replaced after being damaged.

Detailed Description
The present invention will be further described with reference to the following specific examples.
Example 1
A belt safety backstop for a blind inclined shaft comprises two triangular supports which are arranged in parallel, wherein each triangular support comprises a first supporting rod 1 and a second supporting rod 2, an included angle between the two supporting rods is consistent with the gradient of the blind inclined shaft (21 degrees), the first supporting rod 1 is vertically arranged, the tops of the two supporting rods are fixedly connected with a top plate 3 together, and the top plate 3 is connected with the first supporting rod 1 and the second supporting rod 2 in a centered welding mode; the top plates 3 are rotatably connected with supporting beams 4, as shown in fig. 1, two top plates 3 are respectively fixed with lantern rings with horizontally arranged openings, two ends of each supporting beam 4 are respectively inserted into the two lantern rings, the supporting beams 4 are fixedly sleeved with a plurality of supporting plates 5, holes are drilled on two sides of each supporting plate 5 to penetrate through fixing pins, and the supporting plates 5 are prevented from moving left and right on the supporting beams 4; one end of the supporting plate 5 is fixedly connected to the supporting beam 4, and the other end of the supporting plate can freely rotate along with the supporting beam 4; the upper ends of the two first supporting rods 1 are jointly fixed with a stop beam 6, and the free end of the supporting plate 5 abuts against the stop beam 6.
Further, the first support rod 1 and the second support rod 2 are telescopic, the two support rods comprise an upper part and a lower part which are an upper support rod and a lower support rod respectively, and pin holes are formed in the connecting ends of the upper support rod and the lower support rod and are connected through pin shafts; the bottom end of the lower supporting rod is connected with a connecting lug 8 used for being fixed with the ground, and a hole is formed in the connecting lug 8; the bottom of the lower supporting rod is connected with the connecting lug 8 in a centered welding mode.
