Abstract
The utility model discloses a vehicle-mounted workover rig main rotary drum which mainly solves the problem that a common main rotary drum easily heats up in brake, and structure is complicated. The vehicle-mounted workover rig main rotary drum comprises a box body, a rotary drum shaft is arranged at the center of the box body, one end of the rotary drum shaft is a power input end, the rotary drum shaft is connected with the box body through a bearing and a bearing seat, the outer side of the bearing seat is connected with a bearing cover, and two connection discs are connected with the rotary drum shaft. The connection discs are positioned through a positioning sleeve, the bearing and a shaft shoulder, the connection discs are in key connection with the rotary drum shaft, a rotary drum is connected between the connection discs, brake discs are connected on the inner side and the outer side of each connection disc, and the brake discs are made of materials with a big frictional resistance coefficient. With the structure, in the process of gear shifting, power switching is stable, gear impact load is reduced, and service life of a gear and a driving tooth sliding sleeve is prolonged. Disc type brake is adopted by the main rotary drum of the vehicle-mounted workover rig main rotary drum, a friction contacting area is big, a heat dissipation area is big, temperature rising is small, structure is simple, and service life of equipment can be effectively prolonged. The vehicle-mounted workover rig main rotary drum does not need cooling.
