Abstract
Provided is a mining grind-pushing type car stop. The mining grind-pushing type car stop is arranged at an inclined shaft track conveying pit top grade change point and avoids rolling and running of a tramcar. The car stop comprises an air cylinder, a support, H-shaped steel, a spring component and a steel wire rope. Opening and closing the car stop are achieved by the fact that a push rod of the air cylinder pulls and releases the steel wire rope. The car stop is of a normally closed type. The buffer spring component is arranged on one side of a car stop plate and can effectively absorb overweight impact of the tramcar to the car stop plate, and the service life of the car stop is prolonged. The car stop is high in automation degree and large in bearing capacity, and has the advantages of being easy to operate, safe, reliable and long in service life.
Description
Technical field
The utility model relates to a kind of mining formula stop buffer of turning a millstone, especially a kind of mining formula stop buffer of turning a millstone of air cylinder driven.
Background technology
The common formula of turning a millstone stop buffer is a kind of easy device of manually anti-sport car under the mine, and advantage is easy to operate, and is effective; Shortcoming is to need artificial M/C fully, both wasted labour power, also the safety of coal miner consisted of certain threat, the most serious is that the part workman is in order to seek conveniently, " car one gear " that require on the colliery become " one class of one gear ", even after handing over to the next shift, forget vehicle obstructing plate is turned back make position, and next class workman is under unwitting situation, do not carry out correct operation yet, cause stop buffer to be in the normally open position always, thus, in case the sport car situation occurs, be easy to lead to the grave accidents such as personal injury and equipment damage.
Summary of the invention
In order to overcome the deficiency of mentioning in the background technology, the utility model proposes a kind of semi-automatic improvement, energy-saving safe, long service life for the formula stop buffer of turning a millstone.
The technical scheme that its technical matters that solves the utility model adopts is: installing a cylinder (1) that is assembled with steel rope additional on the formula stop buffer basis of turning a millstone, is semiautomatic control after improving.A kind of mining formula stop buffer of turning a millstone, comprise cylinder (1), bearing support (3), A-frame (2), steel rope (6), steel rope sleeve (7), U-shaped screw (5), roller (4), vehicle obstructing plate (8), spring assembly (10) and column (11), it is characterized in that: fill one group of cylinder on the formula stop buffer side of turning a millstone, be fixed on the bearing support with the U-shaped screw; Vehicle obstructing plate is made by I-beam section, and head end and A-frame are hinged, and end fills one group of spring assembly, and steel rope sleeve is fixed on the vehicle obstructing plate with the U-shaped screw; Cylinder support frame head is equipped with two rollers, and steel rope one end connects cylinder push-rod, by the steel rope sleeve on the roller guiding connection vehicle obstructing plate; After the vehicle obstructing plate closure, spring assembly is corresponding with the column of being made by I-beam section; The column of A-frame is made by I-beam section.Principle of work is: stop buffer is normally closed, without when control stop buffer be in closure state, can stop that mine car goes down the hill, when stop buffer was closed, cylinder push-rod was in the state of stretching out.When mine car travels need to put car and travel by stop buffer the time by track (9), the workman presses explosion-proof Self-resetting Long-distance Control button, and cylinder (1) push rod is regained, and pulls open the version (8) of keeping off a car by pulling steel rope (6), and vehicle passes through subsequently; After vehicle passes through, release button, explosion-proof Self-resetting Long-distance Control button automatically resets, and cylinder push-rod stretches out, and steel rope loosens, and the version of keeping off a car is closed under Gravitative Loads, enters the state of keeping off a car.Edition two ends of keeping off a car respectively fill one group of spring buffer assembly (10), and are corresponding with column, the rigid shock when reducing mine car and knocking vehicle obstructing plate, and the protection stop buffer increases the service life.
The beneficial effects of the utility model are that the unlatching of stop buffer need not artificial rough power operation, improves safety, has reduced labour intensity.The spring buffer assembly of installing reduces mine car to the rigid shock of vehicle obstructing plate, improves the service life of stop buffer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among Fig. 1: 1-cylinder, 2-A-frame, 3-bearing support, 4-roller, 5-U shape screw, 6-steel rope, 7-steel rope sleeve, 8-vehicle obstructing plate, 9-track, 10-spring assembly, 11-column.
The specific embodiment
In Fig. 1, stop buffer is located among the inclined shaft, and the stop buffer normality is closure state, and this moment, cylinder push-rod all stretched out, steel wire rope looseness, and arrester can stop the mine car that travels.When mine car travels when need letting pass by track (9), the workman presses explosion-proof Self-resetting Long-distance Control button, cylinder (1) work, and push rod is regained, and pulls open vehicle obstructing plate by pulling steel rope (6), allows mine car to pass through; After mine car passes through, release button, button automatically resets, the cylinder push-rod auto-extending, steel wire rope looseness, vehicle obstructing plate is auto-closing under Action of Gravity Field, reenters the state of keeping off a car.The vehicle obstructing plate two ends respectively fill one group of spring buffer assembly (10), and are corresponding with column, the rigid shock when the minimizing mine car knocks vehicle obstructing plate.
Claims (5)
