Abstract
The utility model relates to a long-lived bridged overhead travelling crane brake, of which the basic structure is as same as present bridged overhead travelling, comprising a socket and two relevant brake arms fixed on both sides of the socket, wherein two relevant brake scotches are arranged on inner side of brake arms, a braked wheel is locked between two brake scotches. The utility model is characterized in that a dust helmetis equipped on the top of the braked wheel. The utility model prevents dust from dropping on the braked wheel by fixing a rubber on the braked wheel which is sheared in accordance with the size of the braked wheel, thereby extending life time of the brake, reducing the maintaining cost, lightening the work of maintaining, improving safety of operation, solving the overproof attrition problem of the brake when working in an environment of too much dust. The life time of the utility model can be two or more years.
Description
Technical field
The utility model relates to a kind of long life bridge overhead travelling crane drg.
Background technology
Bridge overhead travelling crane drg major part all is to utilize the braking that is used of hydraulic braking frame or electromagnetic braking frame and brake shoe brake wheel.In the aluminum smelting technology industry, because the factory dust is bigger, the brake wheel surface often falls into a large amount of dust, make that the deceleration and stopping performance of drg is bad, influence the normal operation of production facilities, and the wearing and tearing that this situation has been quickened drg scrap, increased the maintenance cost and the input cost of equipment.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of long-life bridge overhead travelling crane drg is provided.
As follows for realizing the technical scheme that the purpose of this utility model adopted:
A kind of long life bridge overhead travelling crane drg, comprise base and be located at corresponding two brake control levers in base two ends, the medial surface of described brake control lever is provided with two corresponding brake scotch, and brake wheel is clipped in the middle of two brake scotch, it is characterized in that: be provided with dust boot above above-mentioned brake wheel.
The utility model utilizes common rubber to be cut into according to the size of braking wheel carrier, be fixed on the brake wheel top then, prevent that dust from dropping on the brake wheel, thereby prolong the service life of drg, reduce maintenance cost, alleviate maintenance capacity, improve the equipment operation safety, rationally solve the exceed standard wear problem of drg under high dust atmosphere.
Use common bridge overhead travelling crane drg, all need every year to change or pull down the reparation brake wheel, and can extend to more than the two-and-a-half years service life of the utility model drg.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model long life bridge overhead travelling crane drg;
Fig. 2 is the structural representation sketch of dust boot in the utility model.
The specific embodiment
Long life bridge overhead travelling crane drg basic structure of the present utility model is with the bridge overhead travelling crane structure unanimity of prior art, as shown in Figure 1, the pusher 3 that comprises base 1, is installed in the brake control lever 2 at base 1 two ends, links to each other with brake control lever 2 by adjusting lever 7, lever 8, spring frame 9 one ends are fixed on the lever 8, and the other end is located near on the brake control lever 2 of pusher 3; Be provided with two corresponding brake scotch 4 in the inboard of brake control lever 2, brake wheel 5 just is located between two brake scotch 4.Present technique adopts above brake wheel 4 and installs the service life that dust boot 6 prolongs drg.Dust boot 6 is to be fixed on two brake control levers 2 by connecting device.
