Hydraulic rotary power device

Abstract

The invention relates to a hydraulic rotary power device and belongs to the technical field of anchor rod detection torque loading devices. The invention aims to provide the hydraulic rotary power device which is stable, safe and reliable in running and can output the double power. The technical scheme provided by the hydraulic rotary power device is that a first machine head bracket and a second machine head bracket are arranged above the two ends of a first machine head bottom plate; a first hollow high-speed shaft of a high-speed motor is sleeved on the first machine head bracket and the second machine head bracket; the high-speed motor is fixed on the first machine head bracket; a first torque sensor is sleeved on the first hollow high-speed shaft; a low-speed motor is sleeved on the first hollow high-speed shaft through a first low-speed shaft; the first torque sensor and the low-speed motor are positioned between the first machine head bracket and the second machine head bracket; the first torque sensor is fixed on the first machine head bracket; and one end of the low-speed motor is connected with and fixed with the first torque sensor through a third flange. The hydraulic rotary power device is mainly used for detecting the uploading of rotating power of an anchor rod.

Description

technical field [0001] The invention relates to a hydraulic rotary power device, which belongs to the technical field of bolt detection torque loading devices. Background technique [0002] Bolt support, as an advanced active support technology, has been widely used in coal mine roadway support. In order to ensure safety, before the construction of the bolt support project, it is very important to use appropriate methods to conduct a comprehensive inspection of the bolt support materials to ensure that their quality and performance meet the requirements of the relevant support design and relevant standards. However, there is no torque loading device that can simulate bolt drilling, which cannot meet the detection requirements of the comprehensive mechanical properties of bolts. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and the technical problem to be solved is to provide a hydraulic rotary power device that operates smoo...
