Lifting hydraulic capstan for lorry-mounted crane

Abstract

The invention relates to the technical field of lorry-mounted cranes, and discloses a lifting hydraulic capstan for a lorry-mounted crane. The lifting hydraulic capstan comprises a mounting frame anda hydraulic capstan body; a base which is fixedly connected to the bottom of the hydraulic capstan body; a gear fixedly connected to a rotating shaft of the hydraulic capstan body, and located outsidea machine shell of the hydraulic capstan body; four T-shaped fixing plates arranged at the four corners of the top of the base; and four fixing boxes which are fixedly connected to the front sides and the rear sides of the surfaces of the left side and the right side of the top of the mounting frame, and correspond to the four T-shaped fixing plates. By arranging the mounting frame, the hydrauliccapstan body, the base, the T-shaped fixing plates, the fixing boxes, the sliding rod, the sleeve, the threaded rod, the bearing, the adjusting handle, the movable plate, the supporting rod, the sleeve, the clamping block, the fastening bolt and the nut, the base can be further reinforced.

Description

technical field [0001] The invention relates to the technical field of truck-mounted cranes, in particular to a lifting hydraulic winch for truck-mounted cranes. Background technique [0002] In the crane industry, according to the scope of work, the types of cranes can be divided into truck cranes and truck mounted cranes. The truck-mounted crane is a device that realizes the lifting, turning, and lifting of goods through a hydraulic lifting and telescopic system, and is usually assembled on a truck. [0003] At present, the hydraulic winch used for the lifting function installed on the truck-mounted crane still has some shortcomings in some aspects, and needs further improvement. After a long time of work, it is easy to deform or break. If the staff does not notice it in time, it will cause the hydraulic winch to shake when hanging heavy objects, which will affect the working efficiency of the hydraulic winch.
