Jackdrill propelling beam swinging and rotating device

Abstract

The invention discloses a jackdrill propelling beam swinging and rotating device. A top sliding rail and a bottom sliding rail are machined on the top end face and the bottom end face of a propelling beam respectively. A power head assembly for rock drilling is installed on the top sliding rail in a sliding fit mode, a propelling beam compensation frame is installed on the bottom sliding rail in a sliding fit mode, the head of the propelling beam compensation frame is rotationally installed on a swinging oil cylinder shaft frame, and a swinging oil cylinder assembly is installed between the swinging oil cylinder shaft frame and a tail base of the propelling beam compensation frame. The swinging oil cylinder shaft frame is installed on a rotating oil cylinder assembly, and the rotating oil cylinder assembly is installed at the tail end of a jackdrill main arm. The propelling beam swinging device can swing under the effect of a hydraulic oil cylinder, the swinging angle of the swinging device can be within the 0-900-degree range, it is guaranteed that the jackdrill can adapt to rock drilling work of different rock body structures, drilling operation can be carried out without moving equipment, the work schedule of a project is accelerated, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of rock drilling equipment, and in particular relates to a rock drilling machine propulsion beam swing and rotation device. Background technique [0002] At present, the rock drills commonly used in the market have a very small swing angle of the propulsion beam, which has the following defects in engineering practice: [0003] (1) Due to the relatively small swing angle, there are certain limitations in drilling operations, especially when the space is narrow and the rock drill is inconvenient to move. If the propulsion beam cannot swing, it will be restricted on different sides of the rock mass Upper drilling operation; [0004] (2) For multi-propelling beam rock drills, in a narrow space, if the angles of the two propelling rods cannot be adjusted, it may cause interference between the two propelling beams, resulting in failure of normal construction; [0005] (3) For the rock mass of the V-shaped structure, if t...

Problems solved by technology

[0003] (1) Due to the relatively small swing angle, there are certain limitations in drilling operations, especially when the space is narrow and the rock drill is inconvenient to move. If the propulsion beam cannot swing, it will be restricted on different sides of the rock mass Upper drilling operation;

[0004] (2) For multi-propelling beam rock drills, in a narrow space, if the angles of the two propelling rods cannot be adjusted, it may cause interference between the two propelling beams, resulting in failure of normal construction;

[0005] (3) For the rock mass with V-shaped structure, if the swing angle of the propulsion beam is small, it is impossible to perform rock drilling operations on both sides of the V-shaped structure at the same time, and the work efficiency is low

[0006] In addition, the commonly used rock drills on the market, when most of the rock drilling rigs on the market are currently working, the carriage can only swing horizontally, and there are certain limitations in the drilling angle. If it is necessary to drill from different angles in the tunnel Especially when the tunnel space is limited and the equipment cannot be moved and when the lower hole is drilled from the side, the basic operation will seriously affect the work progress and reduce the work efficiency
