Well tower type vertical well lifting joint adjustment test device and method

Abstract

The invention discloses a well tower type vertical well lifting joint adjustment test device and method. The device comprises a supporting foundation, a hydraulic loading device and surrounding anglepositioning plates, wherein a platform I, a platform II and a platform III are arranged on the supporting foundation; two surrounding angle positioning plates are arranged on the platform III along the horizontal and longitudinal directions; and the hydraulic loading device is fixed on the surrounding angle positioning plates along the vertical direction through surrounding angle positioning bolts. Loads on two sides of a winding drum in an actual lifting process are simulated based on a mode of double hydraulic cylinder driving steel wire ropes, normal working conditions such as no load, light load and heavy load can be simulated, and malignant extreme working conditions such as overload and secondary heavy load can be simulated. In addition, the bearing performance of a main shaft device, anti-skid performance of friction pads and braking performance of a brake can be evaluated reliably, a joint adjustment test can be preformed before mounting on site for well tower type vertical well lifting machines with different diameters of winding drums, surrounding angles, numbers of wire ropes and spacing of the wire ropes, and a full-state loading test for the main shaft device is performed, which is of great significance for ensuring the safety of the lifting system.

Description

technical field [0001] The invention relates to a vertical shaft hoist joint debugging test device and method, in particular to a vertical shaft hoist joint debugging test device and method. Background technique [0002] As the main mine hoisting equipment, the vertical shaft hoist is responsible for the important tasks of lifting coal gangue, lowering materials, lifting personnel and equipment, and is the connection hub between the coal mine underground and the ground. The hoist joint debugging test refers to the joint inspection of whether the main shaft device and the braking system can adapt to normal and extreme working conditions after the successful installation of the main shaft device (including the drum, main shaft, and bearing housing), the liner, and the braking system. A key step before hoist installation on site. At the same time, the vertical shaft hoist is a large-scale basic equipment for one-time installation, especially the shaft tower type vertical shaft...

AI Technical Summary

Problems solved by technology

The above research mainly has the following problems: First, the state monitoring of the equipment in service is mainly carried out, but the performance test of the shaft hoist system before installation is lacking, and the latter can uniformly calibrate the different types of shaft hoist systems produced by various manufacturers before installation on site. To avoid repeated testing investment of large-scale production enterprises, improve the manufacturing quality of small-scale production enterprises, and ensure the safety of the lifting system from the source; second, mainly for the detection of a single type of lifting system, which cannot effectively adapt to different reel diameters and volumes. The hoisting system of cylinder wrapping angle, number of wire ropes, and wire rope spacing; third, there is no loading test before installation, and the bearing performance of the main shaft device, the anti-skid performance of the liner, and the braking performance of the brake cannot be accurately evaluated; fourth, The detection of in-service mines cannot effectively utilize the change of characteristic parameters of the spindle device under no-load and heavy-load conditions, which is an important feature for diagnosing defects such as abnormal deformation and cracks of the spindle device. Loading and other vicious working conditions, and the latter is an important reference for judging whether the spindle device, friction lining, and braking system can withstand extreme working conditions
