Abstract
A mine car anti-slip device belongs to a coalmine production auxiliary facility and consists of a mine car connecting plate, a frame body, a pawl, a ratchet wheel and a rolling shaft, wherein the mine car connecting plate is connected with the frame body by a connecting shaft; the pawl is arranged on the frame body; the frame body is connected with the ratchet wheel; the rolling shaft is mounted on the ratchet wheel. When the mine car anti-slip device is braked, the stress is balanced, the braking reliability is further prompted, the braking reliability is high, and the damage to a rail is small.
Description
Technical field
The utility model belongs to coal production auxiliary facilities, is mainly used in colliery track rack rails mine car, is specifically related to a kind of mine car anti-skid device.
Background technology
Under coal mine, for increasing work efficiency, the utilization of mine car is very extensive, and wherein, track rack rails car is just widely used in mine car.
, in the time of Underwell mining transporting cargo, in upward slope process, often there is sport car, slip car accident in the long complications in coal mine inclined shaft tunnel, with a varied topography and with certain gradient.
For avoiding that immesurable risk occurs while slipping car; conventionally coal miner can install a push rod naturally drooping additional at mine car afterbody; in the time that mine car slips car; conventionally can slip after very long distance; push rod just can withstand on track sleeper; to slip in car process potential energy larger, very easily cause danger like this, and serious to the damage comparison of track.
Therefore how in mine car slips car process, to prevent fast and stably it and slip car, avoid the generation of safety misadventure just to seem particularly important.
Summary of the invention
Track is damaged when the anti-running for fear of original anti roll device, for effectively preventing from slipping occurrence risk in car process, the invention provides a kind of mine car anti-skid device simultaneously.
A kind of mine car anti-skid device, is characterized in that being made up of mine car connecting panel, support body, ratchet, ratchet, the axis of rolling five parts, and mine car connecting panel is connected with support body by adapter shaft, ratchet is set on support body, ratchet is freely sagging on support body, and support body is connected with ratchet, and the axis of rolling is arranged on ratchet; Described support body is provided with two axis holes, and the axle that ratchet is installed is arranged in one of them axis hole; The axle that ratchet is installed is arranged in another axis hole; The described axis of rolling is cylinder, 5 equidistant uniform being arranged on ratchet of the axis of rolling; The axis of rolling coordinates with the tooth bar on rack rails.
The present invention unites two into one ratchet and roller, is designed to an axis of rolling, and detent design is on support body, and freely sagging, compact conformation is reliable, and the stressed position of braking is changed on roller and track tooth bar, and braking adopts the reverse check of ratchet to realize.
Stress balance when the utility model braking, has further promoted the reliability of braking.
Compared with existing brake equipment, the utility model braking reliability is high, very little to the damage of track.
Brief description of the drawings
Fig. 1 is constructional drawing of the present utility model.
In figure,
1. connecting panel, 2. support body, 3. ratchet, 4. ratchet, the 5. axis of rolling.
Detailed description of the invention
Shown in Fig. 1, the utility model is made up of connecting panel 1, support body 2, ratchet 3, ratchet 4, the axis of rolling 5 five parts, and connecting panel 1 is connected with support body 2 by adapter shaft, and ratchet 3 is set on support body 2, and support body 2 is connected with ratchet 4, and 5 axis of rolling 5 are arranged on ratchet 4.
Support body 2 is provided with two axis holes, and the axle that ratchet 3 is installed is arranged in one of them axis hole; The axle that ratchet 4 is installed is arranged in another axis hole.
The axis of rolling 5 is cylinder, 5 equidistant uniform being arranged on ratchet 4 of the axis of rolling; The axis of rolling 5 is for coordinating with the tooth bar on rack rails.
Principle of work of the present utility model is: mine car connects support body 2 by connecting panel 1, drives ratchet 4 left-hand revolutions, and ratchet 3 lifts, and the simultaneously each axis of rolling 5 orders match with the tooth bar on rack rails.In the time that mine car slips car due to abnormal condition on ramp, ratchet 3 is braked, and ratchet can not be rotated, and the axis of rolling 5 can not effectively depart from tooth bar simultaneously, finally reaches braking object.
