Abstract
The invention discloses a device for preventing longitudinal tearing of a rubber belt of a belt conveyor. The technical scheme includes that a miniature conveyor is mounted on a progressing rubber belt of the belt conveyor at a feed inlet of a chute, a rubber belt of the miniature conveyor and the rubber belt of the belt conveyor are parallel and identical in direction and speed, the rubber belt of the miniature conveyor rather than the rubber belt of the conveyor is torn longitudinally due to impurities in mineral aggregates, and accordingly, the belt conveyor can run normally. A plurality of drums are mounted between a return belt of the miniature conveyor and the progressing belt of the belt conveyor. During running of the belt conveyor, the drums transmit power to the miniature conveyor by the aid of friction force thereof so as to lead the miniature conveyor to run in the same direction and at the same speed, the miniature conveyor can also be driven by a motor and a speed reducer, and the speed of the rubber belt of the miniature conveyor is higher than or equal to that of the rubber belt of the belt conveyor. In order to guarantee running space of mineral aggregates and power transmission, groove type support rollers at the feed inlet of the chute need to be replaced by parallel support rollers, and the chute can be heightened and enlarged according to needs.
Description
Technical field:
The present invention relates to the conveyor belt running protective device against longitudinal tear.
Background technology:
At the harbour, thermal electric generation, mine, smelter use general all be the travelling apron of long distances; In case generation longitudinal rupture of adhesive tape; Can produce great damage to production facilities, the longitudinal rupture of adhesive tape fault overwhelming majority occurs near the chute feed opening place, and longitudinal rupture of adhesive tape is normally because foreign matters such as the stone that mineral aggregate mixes, wooden unit, iron block have keen edge; The place is blocked at the chute feed opening, causes longitudinal tear thereby scratch and pierce through adhesive tape; The method of the anti-longitudinal rupture of adhesive tape of representative type is at present: after adhesive tape is torn, adopt various induction detecting devices, signal acquisition sends halt command; Prevent to tear expansion; The longitudinal tear damage of adhesive tape can make production normally carry out, and influences normal production operation, not only can cause direct economic loss; And indirect economic loss is more inestimable, is necessary to design a kind ofly can tear device not to take place at chute feed opening place for this reason.
Summary of the invention:
The present invention provides a kind of device, solves the device that longitudinal rupture of adhesive tape takes place at chute feed opening place.
Belt conveyer of the present invention is prevented its characteristic of longitudinal rupture of adhesive tape device: be at chute feed opening place; On the conveyer trace adhesive tape, a miniature conveyer is installed, miniature conveyer is parallel with conveyer trace adhesive tape, in the same way, with speed; Between miniature conveyer backhaul adhesive tape and the conveyer trace adhesive tape many series cylinders are housed; When conveyer moved, the cylinder frictionally was given miniature conveyer with transmission of power, make its in the same way, with the speed operation; Miniature conveyer also can adopt electrical motor acceleration and deceleration machine mode to drive operation, and belt speed is more than or equal to the conveyer belt speed.
Principle of work of the present invention is:
Mineral aggregate is fallen on the miniature travelling apron by material blanking tube; Miniature conveyer is sent into mineral aggregate on the travelling apron; The longitudinal tear that causes of foreign material in the mineral aggregate like this; Just can only occur on the miniature travelling apron, travelling apron greatly reduces in the possibility of blanking port generation longitudinal tear, thereby guarantees that conveyer normally moves.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the present invention is further explained.
Fig. 1: be anti-longitudinal rupture of adhesive tape device mounting structure scheme drawing
The specific embodiment:
Can know from Fig. 1; The anti-longitudinal rupture of adhesive tape device of belt conveyer of the present invention comprises: be installed in chute feed opening place (3); Parallel miniature conveyer (2) in the same way with conveyer (1) trace adhesive tape, and the many series cylinders friction force between relying on pass to miniature conveyer with the conveyer propulsive effort; Make it in the same way with speed, miniature conveyer also can adopt electrical motor acceleration and deceleration machine mode to drive; When miniature conveyer (2) is installed, in order to guarantee the mineral aggregate free air space, and transmission of power, need change the grooved idler pulley at chute feed opening place (3) into parallel idler pulley, in case of necessity with the chute size increase change big.
Claims (2)
1. the anti-longitudinal rupture of adhesive tape device of belt conveyer is characterized in that: at chute feed opening place, install on the conveyer trace adhesive tape a miniature conveyer parallel with conveyer, in the same way, with fast.
2. according to claim 1, miniature travelling apron can be adopted the many series cylinders transmission of drive force between backhaul adhesive tape and the conveyer trace adhesive tape, also can adopt electrical motor acceleration and deceleration machine mode to drive operation.
