Hole-pitch-adjustable drilling device

Abstract

The invention provides a hole-pitch-adjustable drilling device. The device comprises a supporting frame, a first drilling mechanism, a second drilling mechanism, an oil cylinder and a linkage mechanism, wherein the first drilling mechanism and the second drilling mechanism are arranged on the supporting frame in a sliding way; and the oil cylinder is arranged on the supporting frame, is positioned between the first drilling mechanism and the second drilling mechanism and is used for driving the first drilling mechanism and the second drilling mechanism to slide close to each other or far away from each other on the supporting frame by using the linkage mechanism. In the hole-pitch-adjustable drilling device provided by the invention, the two drilling mechanisms are integrated on the supporting frame, hole pitch can be adjusted through the linkage mechanism, and the operation of two holes can be finished at a time, so that the working efficiency of punching is improved; and the operation can be finished by operating the device only by one operator, so that the device is conveniently and reliably operated, and the problems of mutual interference and avoidance of the two drilling mechanisms are solved.

Description

technical field [0001] The invention relates to a drilling device, more specifically, to a drilling device with adjustable hole distance. Background technique [0002] At present, in the mining process of coal mines, mines and engineering tunnels, the drilling and blasting method is still the main method of excavation. Especially in coal mines, because there are special substances such as gas and dust to work. This puts forward very strict requirements on the operating conditions of drilling equipment. [0003] In the prior art, a single-arm or double-arm rock drilling jumbo is mainly used for drilling and then blasting. However, the single-arm rock drilling rig can only complete one hole at a time, the work efficiency is low, and it takes a long time to complete the drilling of the entire section; while the double-arm rock drilling rig improves some work efficiency, but it must be operated by two people Operation, and the two drill booms often fight and interfere with ea...

Problems solved by technology

However, the single-arm rock drilling rig can only complete one hole at a time, the work efficiency is low, and it takes a long time to complete the drilling of the entire section; while the double-arm rock drilling rig improves the work efficiency, but it must be operated by two people. operation, and the two drill arms often fight and interfere with each other during operation

[0004] In the process of researching and developing the present invention, at least also encountered such problems: two rock drilling assemblies or drilling devices are installed on a support frame, the designed space is limited in a small range, and drilling The adjustable distance makes many technical restrictions and overcomes many technical obstacles in the process of designing a structure that can realize the required functions
