Built-in hydraulic winch

Abstract

The invention belongs to the technical field of hydraulic winches, and particularly relates to a built-in hydraulic winch. The built-in hydraulic winch comprises a hydraulic motor, a brake, a planet decelerating mechanism, a coiling block and a support; the hydraulic motor is fixedly connected to a motor connecting disc, the motor connecting disc is fixed into a brake core inner cavity of the brake, a brake core is fixedly connected with the support, the motor connecting disc is located on the inner side of the support, an output shaft of the hydraulic motor is in transmission connection witha wheel shaft of a sun wheel of the plane decelerating mechanism, a gear ring of the planet decelerating mechanism is fixedly connected with the coiling block, and the end, away from the hydraulic motor, of the coiling block and the support are rotatably supported. According to the technical scheme, the length of an axial structure can be shortened, the hydraulic motor can be built in the winch, meanwhile, due to reasonable arranging of a planet carrier, the gear ring and the coiling block, the inner space of the winch can be saved, meanwhile, the premise is provided for the built-in type structure of the winch, process of the manufacturing can be greatly improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of hydraulic winches, in particular to a built-in hydraulic winch. Background technique [0002] The hydraulic winch is one of the key core components of the truck-mounted crane, especially now that the truck-mounted crane is developing towards lightweight, miniaturization, and aesthetics, resulting in an increasingly limited assembly space for its hydraulic winch. However, the current hydraulic winch, especially the cycloid motor hydraulic winch commonly used on the truck-mounted crane, the cycloid motor itself has a long axial structure, and the motor and the motor connection plate are installed outside the winch support. Long, resulting in a longer axial extension of the winch, more exposed parts, a less compact structure, and a larger installation space requirement, which brings inconvenience to the operation and use of the truck-mounted crane. In addition, the most common structure of the planet carrie...

However, the current hydraulic winch, especially the cycloid motor hydraulic winch commonly used on the truck-mounted crane, the cycloid motor itself has a long axial structure, and the motor and the motor connection plate are installed outside the winch support. Long, resulting in longer axial extension of the winch, more exposed parts, less compact structure, and a large installation space requirement, which brings inconvenience to the operation and use of the truck-mounted crane

In addition, the most common structure of the planet carrier of the conventional winch planetary reducer mechanism is the double-arm structure. This structure has good rigidity, but to a certain extent increases the space for structural layout and the difficulty of manufacturing. At the same time, the current planetary reducer The inner ring gear of the mechanism is generally integrated with the reel, the manufacturing process is poor, the cost is high, and the maintenance service in the later period is inconvenient. , the required reel shape is larger
