Embodiment Construction

[0029] The specific embodiments of the present invention will be briefly described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those skilled in the art without creative work Examples, all belong to the protection scope of the present invention.

[0030] Figure 1-Figure 3 The preferred embodiment of the present invention is shown, and it is analyzed in detail from different angles.

[0031] Such as figure 1 , 2 A method for measuring the footage of a boring machine is shown, comprising the following steps:

[0032] Step 1, install the reflective target 1 and the distance measuring device 2. The reflective target 1 is installed above the track 3 of the second transport belt conveyor 4, relatively stationary with the track 3. The distance measuring device 2 is inst...

Abstract

The invention discloses a drilling footage measuring method for a roadheader, and relates to the technical field of drilling footage measuring. According to the measuring method, a distance measuringdevice and a reflecting target are arranged, a laser sensor is used for emitting a laser beam to the reflecting target, the laser beam reflected by the reflecting target is received, and according tothe duration from emitting to receiving of the laser beam measured by a timer, the distance L from the laser sensor to the reflecting target is measured and the drilling footage of the roadheader is automatically measured; and meanwhile, the light return amount C is monitored, whether the laser beam hits the target or not is measured according to the light return amount, and a target searching procedure is started at proper time. The invention discloses the drilling footage measuring method for the roadheader. The drilling footage of the roadheader is automatically measured through the arrangement of the distance measuring device and the reflecting target, automatic measuring replaces manual measuring, the measuring precision is high, and the labor intensity is reduced. Meanwhile, whetherthe leaser beam hits the target or not is judged according to the measured light return amount of the laser sensor, so that a steering engine pan-tilt is started according to requirements, the targetsearching work is carried out, and the accuracy and integrity of distance measuring are further improved.

Description

technical field [0001] The invention relates to the technical field of footage measurement, in particular to a method for measuring the footage of a roadheader based on fusion of a laser sensor and an attitude sensor. Background technique [0002] The excavation footage is the length of the tunnel that is excavated when various shaft chambers are excavated. It is an economic and technical indicator in production statistics. The ratio of production excavation footage to mine output reflects the degree of cooperation between production excavation footage and mining. [0003] The working conditions of the excavation face are complex and changeable. At present, manual measurement is mainly used to calculate the excavation footage. On the one hand, there are problems such as large measurement delay and mixed invalid footage; It is labor-intensive to record underground and measure the excavation footage. [0004] Therefore, in view of the above problems, it is necessary to propos...
