Abstract
The utility model relates to a raise transportation anti-chain-rupture anti-slide-down device for a scraper conveyor, which comprises a fixed support, a rotating shaft and a motion locking device, wherein the fixed support is composed of a cross arm and two support bars fixed to the lower part of the cross arm; the rotating shaft is arranged between the upper parts of the support bars; and the motion locking device is arranged on the rotating shaft. The utility model does not influence the normal operation of the scraper conveyor, and can automatically lock the down-sliding chain and the scraper in case of chain rupture, thereby greatly enhancing the use safety of the equipment, optimizing the use safety of the electromechanical equipment and having an important action on production safety.
Description
Technical field
The utility model belongs to the coal mining technical field, relates in particular to a kind of drag conveyor protector.
Background technology
Hebi coal electricity limited company the 8th colliery is a projecting mine, 24 °～30 ° at mine coal seam inclination angle.Can only construct from top to bottom when cutting the eye driving because of projecting coal bed work plane; So driving produces coal and can only upwards transport; Mine car or land boat lifting are adopted in eight ore deposits in the past, but because hoisting velocity is slow and the easy potential safety hazard that produces, are unfavorable for the development of mine coal roadway driving.Cut now now the mountain driving adopt the 40t drag conveyor upwards the transportation driving produce coal; But in actual use because equipment quality problem, haulage device mismanagement or other reasons cause drag conveyor chain rupture meeting to happen occasionally; The cochain of whole drag conveyor can slide in moment during unloaded drag conveyor generation chain rupture; Gently then damage equipment is heavy then causes casualties for strong wallop, for Safety of Coal Mine Production is buried potential safety hazard.
Find have the correlation technique outline following through retrieval: 1, point out in " analysis of causes of drag conveyor chain rupture accident and prevention "; For workmanship or the bad chain rupture that causes of Operation and Maintenance; I.e. " accident property " chain rupture and because the untimely chain rupture that causes is changed in wear-out part inspection, i.e. " naturality " chain rupture has been done labor and has been proposed preventive action.
2, point out that in recent years, along with the raising of mining mechanization, drag conveyor plays crucial effects for the safety in production of entire working surface in " brief talking drag conveyor chain rupture accident reason and prevent measure ".Drag conveyor coal conveying capacity is bigger, safeguards untimelyly or improper, causes chain rupture easily, affects safety production.Analyze drag conveyor chain rupture accident reason and proposed preventive action.
The utility model content
It is the drag conveyor anti-chain rupture landing problem of transportation of going up a hill that the utility model provides problem to be solved, the drag conveyor that provides a kind of and reduce accident rate, ensures constructor's safety and the improve the equipment safety operation condition anti-chain rupture landing device of transportation of going up a hill.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of drag conveyor is gone up a hill and is transported anti-chain rupture landing device; Comprise fixed support, rotating shaft and action blocking device; Fixed support two fixing support bars below cross-arm and cross-arm are formed; Support bar is provided with rotating shaft between the top, and rotating shaft is provided with the action blocking device.
The action blocking device is by adding two baffle plates that steel plate is processed, and the length of baffle plate is greater than the distance of rotating shaft to the fixed support bottom.
Described support bar is made up of montant and diagonal brace, and the direction of diagonal brace is opposite with the incline direction of action blocking device.
The utility model is for not influence of the drag conveyor that runs well, in case chain and scraper plate that downslide will automatic blocking be blocked in chain rupture occur.Improved the safety that equipment uses greatly, optimized the safety that electromechanical equipment uses, for bigger effect has been played in safety in production.

The specific embodiment
Like Fig. 1,2, shown in 3; A kind of drag conveyor is gone up a hill and is transported anti-chain rupture landing device; Comprise fixed support 1, rotating shaft 2 and action blocking device 3, the action blocking device is by adding two baffle plates that steel plate is processed, and the length of baffle plate is greater than the distance of rotating shaft to the fixed support bottom.Fixed support two fixing support bars below cross-arm and cross-arm are formed, and are provided with rotating shaft 2 between the support bar top, and rotating shaft 2 is provided with action blocking device 3, and support bar is made up of montant and diagonal brace, and the direction of diagonal brace is opposite with the incline direction of action blocking device 3.
As shown in Figure 4, whenever on the drag conveyor of going up a hill a utility model is installed at a distance from 30m, in the drag conveyor normal operation process, each scraper plate with blocking device jack-up, and can not influence normal operation through out-of-date meeting.When conveyer generation chain rupture, scraper plate and chain can glide, and the blocking device reversing holds out against chute to reach scraper plate and chain downslide purpose.
Claims (3)
