Background

Because of the requirement of underground rubble discharge, the rubble in the mining area needs to be transported to a rubble drop shaft by using a side dump type mine car for lifting, and a car stopping lever needs to be used when the side dump type mine car is turned over so as to prevent a mine car hopper from falling into the drop shaft in the turning over process. The fender car thick stick is installed in the front of mine car rollover position among the prior art, and at the in-process of overturning, curb plate turned up before the car hopper unloads the ore deposit, and the outer edge of mine car contacts with the fender car thick stick, plays the effect of keeping off the car, but rubble drop shaft installs the stone crusher, and the fender car thick stick of this mode installation can block the stone crusher operation, makes the unable normal use of stone crusher.

SUMMERY OF THE UTILITY MODEL

The utility model provides a retractable car bumper, its purpose: the mine car hopper is prevented from falling in the process of overturning, and the normal work of the stone crusher is not influenced.

The utility model discloses technical scheme as follows:

a retractable car stopping bar comprises a fixed part, a baffle and a traction assembly, wherein the baffle is rotatably connected with the fixed part, and the traction assembly is connected with the lower part of the baffle and used for drawing the baffle to realize the lowering and the recovery of the baffle; and the baffle plate is contacted with the inner edge of the rear side plate of the car hopper when being placed downwards.

Furthermore, the traction assembly comprises a traction steel wire rope and a direction changing part, the direction changing part is installed on the fixing part, one end of the traction steel wire rope penetrates through the direction changing part and is connected to the lower part of the baffle, and the other end of the traction steel wire rope is used for pulling the traction steel wire rope to enable the baffle to rotate relative to the fixing part.

Further, the redirecting part is a pulley.

Further, the fixed component is a box body, and the baffle is installed between the front side plate and the rear side plate of the box body through the rotating component.

Further, retractable fender car thick stick still includes drive assembly, and drive assembly includes motor, speed reducer and reel, the motor is connected through the shaft coupling with the speed reducer, the output shaft of speed reducer is connected with the output shaft of reel, pull wire rope's end twines on the reel.

Compared with the prior art, the utility model discloses following beneficial effect has: (1) when the tramcar stopping lever works, the baffle is lowered to be in contact with the inner edge of the rear side plate of the mine car hopper, so that the falling phenomenon caused by excessive forward tilting of the mine car can be effectively avoided, and the normal work of the stone crusher is not influenced; (2) when the vehicle blocking lever does not work, the baffle is recovered into the box body, the installation position does not occupy space, wind and rain can be prevented, and the service life is prolonged; (3) the utility model is electrically operated, and is convenient and simple.

Detailed Description

The technical scheme of the utility model is explained in detail below with the attached drawings:

as shown in fig. 1, the retractable car stopping bar comprises a fixing part, a baffle 3 and a traction assembly, wherein the baffle 3 is rotatably connected with the fixing part, and the traction assembly is connected with the lower part of the baffle 3 and used for drawing the baffle to realize the lowering and the recovery of the baffle. The car stopping lever is arranged above the position of the dumping car, and the baffle 3 is contacted with the inner edge of the rear side plate of the car hopper when being transferred, so that the work of the stone crusher cannot be influenced.

Further, the traction assembly comprises a traction steel wire rope 4 and a redirection part, the redirection part is a pulley or a hanging ring, in this embodiment, preferably, the pulley 5 is used as the redirection part, and the pulley 5 is fixedly installed on the lower side of the outer part of the front end of the fixing part. One end of the traction steel wire rope 4 penetrates through the direction-changing part and is connected to the lower part of the baffle 3, and the other end of the traction steel wire rope 4 is used for pulling the baffle 3 to rotate relative to the fixing part.

Further, the fixed component is a box body 1, and the baffle 3 is installed between a front side plate and a rear side plate of the box body 1 through a rotating component. Preferably, the rotating member is a rotating shaft 2. Specifically, in this embodiment, the box body 1 is made of an iron plate with a thickness of 16mm, the rotating shaft 2 is made of phi 36 round steel, the baffle 3 is made of 16# channel steel, the rotating shaft 2 is welded with the baffle 3, and the baffle 3 can swing around the rotating shaft 2. The number of the baffle plates 3 is two, and the two baffle plates are connected together through a traction steel wire rope 4.

Further, retractable fender thick stick still includes drive assembly, drive assembly is electrical system, including motor 8, speed reducer 6 and reel 9, the output shaft of motor 8 is connected through shaft coupling 7 with the input shaft of speed reducer 6, the output shaft of speed reducer 6 is connected with the output shaft of reel 9. Specifically, in this embodiment, the output shaft of the speed reducer 6 is perpendicular to the output shaft of the winding drum 9. The tail end of the traction steel wire rope 4 is wound on the winding drum 9, and the traction steel wire rope 4 is dragged through the forward and reverse rotation of the motor 8, so that the electric operation is realized.

When the mine car is turned over, the starting motor 8 lowers the two baffle plates 3 through the traction assembly, and the baffle plates 3 are blocked at the inner edge of the rear side plate of the mine car hopper, so that the phenomenon that the mine car hopper falls off in the turning over process is effectively avoided, and the normal work of the stone crusher is not influenced; after the overturning is finished, the rear baffle 3 is retracted, the mine car moves forward, and the process is repeated by the next mine car.

As shown in fig. 2, when the car stopping lever does not work, the baffle 3 is recovered into the box body 1, the installation position does not occupy space, wind and rain can be prevented, and the service life is prolonged.
