AI Technical Summary

Technical Problem

During the installation and drilling process of drill rods on mining rigs, radial displacement and thread deviation of the drill rods are prone to occur, leading to connection failure. In addition, the existing multi-stage hydraulic cylinder limiting method is complicated and costly.

Method used

The straightening device, which adopts a purely mechanical structure, includes a drill rod assembly, a drill rod block, a rotating shaft, and a spring. It restricts the swaying of the drill rod through an arc-shaped clamp and a spacer, and uses the spring to provide an automatic yielding function, thereby realizing the automatic straightening and yielding of the drill rod.

Benefits of technology

It effectively resists equipment vibration, prevents drilling deviation, reduces system complexity and cost, ensures drilling accuracy and smooth operation, and improves the durability and ease of maintenance of the device.

Abstract

The present application belongs to the technical field of mine drilling mechanical equipment, and discloses a mining trolley drill rod automatic righting device, which comprises a drill rod righting assembly, the drill rod righting assembly is fixedly assembled at the top end of the boom assembly of the mining trolley, the drill rod righting assembly comprises a drill rod righting device body, drill rod righting blocks, a rotating shaft and a spring, the rotating shaft is fixedly inserted into the drill rod righting device body, the two drill rod righting blocks are hingedly sleeved on the rotating shaft, and the spring is fixedly connected with the two drill rod righting blocks at both ends, respectively. The drill rod righting blocks are arranged in pairs, the drill rod is clamped under the elastic force of the spring, the pure mechanical structure is adopted to replace the hydraulic cylinder hydraulic limiting, not only can the device offset the equipment vibration, avoid the drilling deflection, drill rod thread butt joint misplacement and drill rod jamming failure, but also the device is small in size and light in weight, can be directly installed at the front end of the advancing beam, the drill rod righting blocks can be automatically opened and closed to give way when the drill rod is connected and disconnected, the device is simple in installation and use, and does not affect the normal drilling operation of the drilling machine.
