Embodiment 1

[0035] see figure 1 , figure 2 , the present invention discloses a roadway profile generating device, which includes: a light and shadow generator 1, a distance measuring device (including a signal receiving mechanism 21 arranged close to the light and shadow generator, and a signal transmitting mechanism 22 arranged on a roadheader 3) . Wherein, the light and shadow generator 1 can be a laser generator or a projection device; the signal receiving mechanism 21 can be arranged in the housing of the light and shadow generator 1; the signal transmitting mechanism 22 can be a distance-measuring reflector, and the distance-measure reflector passes through the reflector The support is fixed on the boring machine 3 .

[0036] Such as figure 2 As shown, the light and shadow generator 1 includes a main control circuit 11, a first light-emitting component 12, a light-emitting adjustment mechanism 13, a second light-emitting component 14, and is equipped with a remote control 15. Th...

Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 is that in this embodiment, please refer to Figure 7 , the light and shadow generator 1 is a projection device; the light-emitting adjustment mechanism is used to adjust the focusing lens of the projection device.

[0057] The luminescence adjustment mechanism includes an up and down adjustment motor 134 and a left and right adjustment motor 135; the projection device includes a high-intensity light source, a condenser mirror, an image film, a focusing lens, up and down guide rails, and a left and right guide rail. The up and down adjustment motor 134 and the left and right adjustment motor 135 respectively adjust the focusing lens to move on the upper and lower guide rails and the left and right guide rails, and are respectively used to adjust the angle B in the vertical direction and the angle A in the horizontal direction.

[0058] The using method of the present invention is:

[0059] Step 1. Follow the attac...

Abstract

The invention discloses a roadway outline generation device. The roadway outline generation device comprises a shadow generator and a distance measurement device, wherein the shadow generator comprises a master control circuit, a first light emitting assembly and a light emitting adjusting mechanism, the master control circuit is connected with the first light emitting assembly and the light emitting adjusting mechanism, the light emitting adjusting mechanism is connected with the first light emitting assembly, the distance measurement device is used for measuring a distance signal for the distance between the shadow generator and the end of a roadway, and sending the measured distance signal to the master control circuit, the first light emitting assembly is used for emitting a light source, and the light emitting adjusting mechanism is used for adjusting the emitting angle of the first light emitting assembly. According to the roadway outline generation device, the outline of the roadway can be irradiated to the end of the roadway in a multi-point laser mode, visual roadway outline light spots are formed, related staff can conveniently observe the situation at the end of the roadway when a heading machine carries out downhole working, and thus control staff of the heading machine can be helped to improve cutting accuracy of the heading machine and improve drivage efficiency.

Description

technical field [0001] The invention belongs to the technical field of coal shearer auxiliary equipment, and relates to a contour generating device, in particular to a roadway contour generating device. Background technique [0002] When the roadheader is working underground, the visibility conditions are poor, and the spray and cutting dust are very large when the roadheader is working, resulting in extremely poor vision. Under such line of sight conditions, in order to ensure that the roadway excavation quality meets the requirements, the driver of the roadheader must always pay attention to the excavation position of the cutting head of the roadheader to ensure that the roadway is excavated into the predetermined roadway shape. [0003] This causes the driver of the roadheader to constantly change the position to observe, and at the same time use the searchlight to continuously track and illuminate the end of the roadway. Even so, it cannot be guaranteed to see clearly, ...
