Abstract
The utility model relates to an important part of a coal mine tunnel roadheader, in particular to a device preventing a cutting arm from impacting a shovel board, which resolves the problem that a cutting arm is easy to impact a shovel board in heading operation of an existing roadheader. The impact resistant device installs tilt sensors on both the cutting arm and the shovel board, the tilt sensors on the cutting arm and the shovel board are respectively connected with an electric control system which controls early-warning. The impact resistant device can greatly increases heading work efficiency and reduce the working intensity of operators. By installing tilt sensors on both the cutting arm and the shovel board, the impact resistant device has simple structure, convenient installation and improved reliability.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of anti-cutting arm collision shovel board device, is used to prevent tunneling machine cutting arm and shovel board anticollision.
Background technology
At present, when excavation operation, cutting arm needs up and down back and forth cut, and very big thrust is arranged with development machine in the colliery, and existing development machine structure weak point is: the easy and shovel board collision of cutting arm, cause damage of components.So, be starved of the collision prevention device of a kind of cutting arm and shovel board, improve the operating efficiency of driving, reduce operator's labour intensity.
The utility model content
The purpose of this utility model is to provide a kind of anti-cutting arm collision shovel board device, solves the problem that cutting arm is easy and shovel board is collided when having the development machine excavation operation now, and this device can increase substantially headwork efficient, greatly reduces operator's working strength.
The technical solution of the utility model is:
A kind of anti-cutting arm collision shovel board device, this device is for to be separately installed with obliquity sensor on cutting arm and shovel board.
The beneficial effects of the utility model are:
1, the anti-cutting arm collision of the utility model shovel board device, be contained in respectively on cutting units and the shovel board with two obliquity sensors, measure the relative angle of cutting units and shovel board, by the electric control system controls early warning, the collision of cutting arm and shovel board improves reliability when avoiding the development machine operation.
2, the anti-cutting arm collision of the utility model shovel board device is simple in structure, easy for installation.
Description of drawings
Fig. 1 is the structure chart of the anti-cutting arm collision of the utility model shovel board device.
Among the figure, 1 cutting arm; 2 shovel boards; 3 electric-control systems; 4 obliquity sensors.
The specific embodiment
As shown in Figure 1, the utility model is anti-cutting arm collision shovel board device, cutting arm 1 all is equipped with obliquity sensor 4 with shovel board 2, and cutting arm 1 is connected with the electric-control system 3 of development machine body respectively with obliquity sensor 4 on the shovel board 2, and electric-control system 3 is controlled early warning by alarm.
The course of work of the present utility model is as follows:
Obliquity sensor 4 detects the relative angle of cutting arm 1 and shovel board 2 respectively, and sends the detection signal of obliquity sensor 4 to electric-control system 3 respectively, when the relative angle of cutting arm 1 and shovel board 2 reaches preset value, by electric-control system 3 control early warning.
Claims (1)
1, a kind of anti-cutting arm collision shovel board device, it is characterized in that: this device is for to be separately installed with obliquity sensor on cutting arm and shovel board.
