Hoisting device for underground exploration

Abstract

The invention relates to a hoisting device, in particular to a hoisting device for underground exploration. The hoisting device comprises a coiling block, a driving motor, a synchronous belt, a synchronous belt wheel and a speed measurement encoder; the driving motor is used for driving the coiling block to rotate, the coiling block is wound with the synchronous belt, the synchronous belt wheel is arranged below the coiling block and is in smooth and straight fit with the synchronous belt, and the speed measurement encoder is used for measuring the rotating speed of the synchronous belt wheel and feeding back measurement signals to a control system; and the control system conducts real-time control over the rotating speed of the coiling block through the driving motor according to the rotating speed of the synchronous belt wheel, and therefore the synchronous belt is hoisted and drops at a constant speed. According to the hoisting device for underground exploration, as the driving motor is controlled to driving the rotating speed of the coiling block by measuring the rotating speed of the synchronous belt wheel, the hoisting device can be hoisted or can drop at a constant speed, and the stable dropping speed, the stable rising speed and the high-accuracy position control are achieved. Meanwhile, a steel wire rope is replaced with the synchronous belt, a winding displacement mechanism used for winding of the coiling block is omitted, and the complexity of the hoisting device is reduced.

Description

technical field [0001] The invention relates to a lifting device, in particular to a lifting device for underground detection. Background technique [0002] At present, there are many devices used for underground hoisting. The existing hoisting devices are mainly composed of a drum and a wire rope. The movement speed of the wire rope and the control system do not form a closed-loop control. Therefore, there are fluctuations in the hoisting speed, and the hoisting position accuracy is difficult to control. In order to increase the winding performance on the reel, the existing lifting device generally has a special cable arrangement mechanism, which makes the existing lifting device more complicated. Contents of the invention [0003] The object of the present invention is to provide a lifting device for downhole detection to solve the above problems. [0004] An embodiment of the present invention provides a hoisting device for downhole detection, including a reel, a drive...
