Embodiment 1

[0024] The sliding nut, the worm, and the clutch module A move synchronously with the screw in the axial direction of the power drive shaft; the rotation of the screw moves the sliding nut, pushing the worm and clutch A to move accordingly; the inclination angle of the creeping wheel group 1.9 changes, The radius of motion of the crawling drive wheel and the contact pressure with the hole wall will change accordingly.

[0025]Further, a pressure sensor 13 is installed at the contact part between the fixed bracket 12 and the connecting bracket 1.4, and the pressure sensor can also be set in the groove of the contact part between the worm 1.1 and the sliding nut 2.2, so as to detect the difference between the crawling wheel set and the hole wall when crawling. contact pressure between.

[0026] Further, the clutch mechanism A3 includes a driven flange A3.1, a clutch module A3.2 and a telescopic pin A3.3, and the telescopic pin A3.3 is set in the clutch module A3.2, and is contro...

Embodiment 2

[0028] Further, the front end of the power drive shaft 5 is provided with a chute 5.1, and the clutch module A3.2 is provided with a raised slide table 3.4 in the direction of the installation shaft, and the slide table 3.4 is connected with the chute 5.1 on the power drive shaft. Cooperate, it can move in the axial direction of the power drive shaft, and rotate synchronously with the power drive shaft in the radial direction.

[0029] The present invention is an underground deep-hole heavy-load cable traction method. When the underground deep-hole heavy-load cable traction device adopts the above-mentioned method, when the traction cable or other equipment normally moves forward or exits, the controller of the electric control board 8 controls the motor 7 to drive The power shaft 5 rotates, the clutch mechanism A3 is opened, the power drive shaft 5 drives the worm 1.1, and drives the crawling wheel group 1.9 to move forward or withdraw from the movement; When the sensor detec...

Abstract

The invention relates to an underground deep hole heavy load cable type traction device and method. The device at least comprises a shell, a clutch A, a crawling movement mechanism, a hole self-adaptive adjusting mechanism, a clutch B, a motor and an electric control panel, the clutch A, the crawling movement mechanism, the hole self-adaptive adjusting mechanism, the clutch B, the motor and the electric control panel are sequentially arranged in the shell, the motor is connected with a power driving shaft through a coupler, and the clutch A, the crawling movement mechanism, the hole self-adaptive adjusting mechanism and the clutch B are all arranged on the power driving shaft; the hole self-adaptive adjusting mechanism comprises a lead screw and a sliding nut, the power driving shaft is sleeved with the lead screw, the lead screw is sleeved with the sliding nut, and one end of the sliding nut is clamped in a groove of a worm of the crawling movement mechanism in a sleeved mode. The lead screw at the other end of the sliding nut is fixedly connected with the clutch B. The other end of the worm is fixedly connected with the clutch A. The device has the advantages of being simple in structure, large in traction force, capable of advancing and retreating, capable of being recycled and the like.

Description

technical field [0001] The invention relates to a deep hole traction device, in particular to an underground deep hole heavy-load cable traction device and method. It belongs to the field of deep hole crawling traction. Background technique [0002] With the deepening of coal mine mining, the number of exposed aquifers increases and the mining of coal seams close to strong aquifers increases the number and amount of water inrush in mines, resulting in more frequent well flooding accidents. Therefore, research on the water inrush mechanism of karst fissure water threats to coal seams Water pollution and water prevention have become major issues that affect the safety of coal mine production and need to be resolved. With the continuous development and application of monitoring technology in the field of coal mines, holes are drilled in the floor of the roadway and corresponding sensors are arranged in the holes to continuously and actively monitor the damage depth of the floo...
