Abstract

The invention relates to a hydraulic brake device. The hydraulic brake device comprises a water inlet connector which is mounted on a stator, the stator is fixed on a shell by a bolt; a spindle is mounted on the shell through a bearing, a first shaft sleeve and a second shaft sleeve; an external end is axially located by an end cover and fixed on the shell by a screw; a rotor is fixed on the spindle by the bolt through a first baffle, a slippage gear is mounted on the spindle through a spline structure, a shifting block is driven by a shifting fork to axially slide along the spindle, and a right end face is fixed by the second baffle and the bolt; the shifting fork is fixed on a support through a first locating sleeve and a second locating sleeve; the shifting fork is mounted on the shifting forking shaft through a flat key to perform the synchronous shifting; a handle is fixed on a handle base through the thread, and the handle base is connected with the shifting fork shaft through alocating pin. The hydraulic brake device provided by the invention is safe and reliable, can stably control the descending speed of a drilling tool in labor-saving, is easy to operate, stable and labor-saving, convenient for maintenance, and low in manufacturing and maintenance cost and strong in applicability, and can adapt to adverse work condition of the drilling tool.

Description

technical field [0001] The invention relates to a water brake device. Specifically, a water pump is used to supply water to the water brake housing, so that the rotor generates resistance, hinders the rotation of the rotor, realizes the function of controlling the descending speed of the drilling tool, and finally realizes the control of the descending speed of the drilling tool. It belongs to construction machinery (rig) field. Background technique [0002] In the prior art, the working conditions of the drilling construction are harsh, and the structure of the machine is designed according to the principles of simplicity, practicality, safety and reliability; it is required to be easy to install and disassemble, and easy to maintain, so it is suitable for use in field areas. When drilling into a deep hole, the weight of the entire set of drill pipes will exceed 10 tons. The commonly used method is to rely on the descending brake to control the descending speed or brake. A...
