Abstract
The utility model relates to an anti-slide device of the tramcar; the invention installs a centrifugal brake shoe (1) on the inner plate (2) of the tramcar wheel; fixedly installs a brake stop block plate (4) on a wheel shaft (5) of the tramcar. When the wheel reaches a certain speed, the centrifugal force makes the centrifugal brake shoe (1) contact with the brake stop block (3) on the brake stop block plate (4), namely, the brake stop block (3) stops the centrifugal brake shoe (1), and thus making the inner plate (2) of the tramcar wheel which is connected with the centrifugal brake shoe (1) unable to turn. Therefore, the tramcar stops sliding downwards and realizes the anti-slide function.
Description
The utility model relates to the anti-big sliding device of mine car.
In the go-downhill roadway, break by the wire rope that occurs the traction mine car sometimes on the shaft bottom for mine car, out of stock or unexpected power failure of winch and brake failure phenomenon, because the last go-downhill roadway ratio of slope is steeper, it is promptly big sliding easily to cause mine car to glide fast.Because inertia, mine car can be rushed in the shaft station until well head, very easily causes casualties and device damage.
For addressing this problem, common way is to place velocity transducer on tramroad, the induction mine car whether exceed the speed limit, or on winch front end wire rope roller bearing the placement force sensor, the induction wire rope whether break.Then, go up the blocker action of go-downhill roadway bottom by sensor control again, block mine car.
Because subsurface environment is more abominable, humidity and dust are all bigger, and sensor is easy to malfunctioning.When big sliding akinesia often takes place, even action, because blocker is to be in the go-downhill roadway bottom, it is quite fast to slide into this place's speed under the mine car, and impact force is very strong, and blocker is damaged; Simultaneously fast the mine car that glides is subjected to suddenly stopping and easily overturns, slides down, and the mine car of back squeezes on the mine car of pounding in front, causes mine car impaired.
The purpose of this utility model is that a kind of anti-big sliding device that is contained on the mine car wheel will be provided, and it can be prevented sliding greatly effectively and not make mine car overturn, slide down impaired.
The purpose of this utility model is achieved in that installs the centrifugal hoof piece of brake on the inner disc of each wheel of mine car, brake block dish is installed on wheel shaft, on the brake block dish brake block is arranged.When the wheel turns of mine car, the centrifugal hoof piece that brakes is subjected to centrifugal action to overcome the pulling force of hoof piece extension spring, outwards upholds.Along with rotating speed improves, centrifugal force increases, the outside more extension of centrifugal hoof piece of braking.When reaching certain rotating speed, the centrifugal hoof piece that brakes contacts with brake block on the brake block dish.Because brake block dish is to be fixedly mounted on the wheel shaft, can not rotate, the centrifugal hoof piece that therefore brakes is blocked and can not rotates.And the centrifugal hoof piece that brakes is to be fixed on the wheel inner disc, so wheel also just can not rotate, and mine car just is forced to stop gliding, thereby plays anti-big sliding effect.
The utility model is because only need be in that installation brake block dish on centrifugal hoof piece of brake and the wheel shaft is installed on the inner disc of wheel, so simple in structure; Owing to be to utilize centrifugal force, answer the speed of a motor vehicle and action by mechanical sense, thereby move reliable and stable simultaneously; Owing to be mine car self braking, not that the external world stops in addition, thereby unlikelyly overturn, slide down, the mine car damaged phenomenon.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the theory structure schematic representation according to the anti-big sliding device of the mine car that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This device is to be made of brake centrifugal hoof piece (1) and brake block dish (4) two major parts.The centrifugal hoof piece (1) that brakes fuses by shoe piece fixing pin (6) and wheel inner disc (2), and the centrifugal hoof piece (1) that brakes can freely rotate along shoe piece fixing pin (6).When the wheel rotor speed improves, centrifugal force increases, and the centrifugal hoof piece (1) that brakes just overcomes hoof piece extension spring (7) and contacts with brake block (3) on the brake block dish (4).Because brake block dish (4) is to fixedly connected to be integral with wheel shaft (5), and the centrifugal hoof piece (1) that brakes is to fixedly connected with wheel inner disc (2) to be integral and to rotate along wheel shaft (5), so when the centrifugal hoof piece of brake (1) with brake block (3) when contacting, the centrifugal hoof piece (1) that brakes just is blocked, cause wheel inner disc (2) not rotate along wheel shaft (5), mine car just stops gliding like this, thereby realizes that mine car is anti-big sliding.
Claims (2)
1. the anti-big device of sliding of mine car is characterized in that upward installation brake centrifugal hoof piece (1) of mine car wheel inner disc (2), and Bogie truck axles (5) is gone up and fixedly mounted the block dish (4) that brakes, and on the block dish (4) that brakes brake block (3) is arranged.
2. require described device according to right 1, the centrifugal hoof piece (1) that it is characterized in that braking is to be connected by hoof piece extension spring (7) by two semicircle hoof pieces to constitute.
