Abstract
The utility model discloses a reducer brake device for an oilfield pumping unit and belongs to the technical field of reducer brake. The reducer brake device comprises a belt pulley, a brake handle, a brake band, a bolt and a rivet, wherein one end of the brake handle is connected to a box cover of the reducer through the reducer; the other end of the brake handle is connected to the belt pulley through the bolt; and the brake band is fixed at an arc b of the brake handle through the rivet. The reducer brake device has the beneficial effects that the belt pulley drives the reducer and can play a role in braking; and in addition, the transmission device and the brake device are arranged at the same end of the driving shaft, the structure is simplified, and the brake device is convenient to use and maintain, so that the equipment is fully utilized, and the resources are saved.
Description
Technical field
The utility model relates to a kind of braking device, specifically is a kind of braking device of used for oil-field oil pumper retarder, belongs to retarder braking technology field.
Background technique
In the prior art at present, oil-field oil pumper retarder commonly used has an independent cover braking device when braking, need brake wheel be installed at the other end of driving shaft; And package assembly more complicated; It is also convenient inadequately to use, safeguard, braking and transmission simultaneously is installed in the two ends of driving shaft respectively, makes driving shaft that other necessary equipment can't be installed again; Cause equipment to be not fully utilized, the waste resource.
Summary of the invention
Problem to above-mentioned existing technology existence; The utility model provides a kind of braking device of used for oil-field oil pumper retarder; Realize that belt pulley can also play the effect of braking when driving retarder, realize the same end installation of transmission and braking device in addition at driving shaft.
To achieve these goals; The utility model is realized through following technological scheme: a kind of braking device of used for oil-field oil pumper retarder; Comprise belt pulley, brake lever, brake strap, bolt and rivet; One end of brake lever is connected through bolt on the case lid of retarder, and the other end of brake lever is connected on the belt pulley through bolt, and brake strap is fixed on the circular arc b place of brake lever through rivet.
Bolt is an articulation bolt, and the below of its nut is provided with a section that plays the rotating shaft effect.
The beneficial effect of the utility model is: realize that belt pulley can also play the effect of braking when driving retarder; Realize the same end installation of transmission and braking device in addition, simplified structure, easy to use, maintenance at driving shaft; Equipment is fully used, saves resource.
