Abstract

The invention relates to a hydraulic capstan for the underground construction field. The hydraulic capstan comprises a capstan support, a three-channel swivel joint, a supporting seat, a spliced capstan body, a speed reducer, a hydraulic motor, a capstan guide frame and an oil pipe transition plate, wherein the hydraulic motor, the speed reducer, the three-channel swivel joint and the spliced capstan body are fixedly installed on the capstan support, the capstan support is fixed to the supporting seat through bolts, plastic resin separating plates used for separating oil pipes are arranged in the spliced capstan body, the ends of the hydraulic oil pipes are connected to the oil pipe transition plate, and the capstan guide frame is arranged on the outer side of the spliced capstan body. Compared with the prior art, the hydraulic capstan is compact in design structure, low in mass, convenient to mount and demount, capable of effectively protecting the oil pipes against abrasion and ensuring the synchronization of the multiple oil pipes, large in torque outlet, high in tensile strength and good in bending resisting rigidity.

Description

technical field [0001] The invention relates to a hydraulic winch, in particular to a hydraulic winch used in the field of underground construction. Background technique [0002] In order to meet the development requirements of submersible drilling rigs, it is necessary to solve the power input problem of the underground power head and also the synchronization problem that can satisfy the simultaneous output of three hydraulic oil pipes, which is one of the technical problems to be solved urgently in this field. [0003] The Chinese Patent Application No. 201110115439.5 discloses a hydraulic winch, which includes a platform, an engine, a hydraulic control valve group and a hoist are installed on the platform, outrigger cylinders are respectively fixed at the four corners of the platform bottom plate, and booms are hinged at the four corners of the platform panel. The end of the boom is hinged with the end of the support arm, the boom is hinged with one end of the boom cylind...
