Problems solved by technology

But, when controlling the propulsion stroke of the rock drill by the travel switch, one travel switch can only control one propulsion stroke
When it is necessary to change the propulsion stroke, it cannot be controlled by the stroke switch
That is, when the propulsion stroke of the rock drill is controlled by the travel switch, it cannot be adjusted conveniently.
[0004] Therefore, how to solve the problem that the propelling stroke of the existing rock drilling machine is not easy to adjust is a technical problem that those skilled in the art need to solve

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as figure 1 As shown, the propulsion device for the rock drilling machine 8 of the present invention includes a propulsion beam 3 , a sliding base plate 9 and a propulsion cylinder 10 respectively arranged on the propulsion beam 3 , and a displacement sensor 19 disposed on the propulsion cylinder 10 . The sliding bottom plate 9 is movably arranged on the propulsion beam 3 , and the rock drilling machine 8 is fixed on the sliding bottom plate 9 . When in use, push the sliding bottom plate 9 to move through the propulsion cylinder 10, and drive the rock drill 8 to move through the sliding bottom plate 9.

[0024] The displacement sensor 19 is used to monitor the displacement of the sliding bottom plate 9 in real time, so as to obtain the drilling depth of the rock drill 8 through the displacement of the sliding bottom plate 9 . Since the displacement sensor 19 c...

Abstract

The propulsion device for the rock drilling machine of the present invention comprises: a propulsion beam; a sliding bottom plate, which is movably arranged on the propulsion beam, and is used for setting the rock drilling machine; a propulsion oil cylinder, which is set on the propulsion beam, and is used for pushing the sliding bottom plate to move; and displacement The sensor is arranged on the propulsion oil cylinder and is used for real-time monitoring of the moving position of the sliding bottom plate. Since the displacement sensor can monitor the displacement of the rock drill in real time, it is necessary to directly set the displacement sensor when the drilling depth needs to be changed, so that it can respond accordingly when the sliding floor moves to the required amount of movement.

Description

technical field [0001] The present invention relates to the technical field of rock drilling rigs, in particular to a propulsion device for a rock drilling machine, and also to a rock drilling rig equipped with the above propulsion device. Background technique [0002] Rock drilling jumbo, also called drilling jumbo, is a kind of rock drilling equipment used in tunnel and underground engineering construction by drilling and blasting method. [0003] A rock drilling jumbo generally includes a propelling beam, a propelling oil cylinder and a sliding base plate arranged on the propelling beam, and a rock drill fixed on the sliding base plate. When in use, the sliding bottom plate is pushed by the propulsion beam to drive the rock drill to complete the drilling. In order to facilitate the control of the propulsion stroke of the rock drill, a travel switch is usually provided on the propulsion beam. After the rock drill touches the limit switch, the limit switch is activated an...
