Problems solved by technology
[0002] During the excavation process of the underground roadway, in order to ensure the safety of the excavation, it is necessary to carry out anchor protection on the excavated roadway in time. In related technologies, the anchor protection of the roadway is mostly anchored and shotcrete support, that is, through the method of bolting and laying nets. Realize the support for the surrounding rock of the roadway, but in the related technology, the net laying support is mostly completed by underground workers, the work is labor intensive and the support efficiency is low

Embodiment Construction
[0042] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0043] Such as figure 1 As shown, the anchor net and anchor protection operation vehicle in the embodiment of the present invention includes a vehicle body and an anchor net actuator. The vehicle body can be a crawler-type walking device, an explosion-proof rubber wheel walking device, etc. It is fixed on the vehicle body by fasteners such as bolts.
[0044] Such as Figure 2 to Figure 11As shown, the net laying actuator 100 includes a first arm 1, a second arm 3, a first driving device 2, a connecting seat 8, a second driving device 7, a swing frame 12, a third driving device, a rotating frame 15, a fourth The driving device 13 , the support frame 4 and the f...

The invention discloses a net laying method based on an anchor net anchor protection operation vehicle, which comprises the following steps: S1, switching on a power supply of an electromagnet, then manually placing an anchor net on a support frame, and adsorbing and fixing the anchor net through the electromagnet; s2, the second arm is rotated to the front side of the first arm, and then the first arm and the second arm are controlled to stretch till the supporting frame and the roadway top plate are spaced by a set distance; s3, the supporting frame is adjusted to be parallel to the roadway top plate through a second driving device and a third driving device, then the circumferential direction of the supporting frame is adjusted through a fourth driving device, and the length direction of the supporting frame is made to be consistent with the width direction of the roadway; s4, the supporting frame is driven to move horizontally through a fifth driving device, and the symmetry axis of the anchor net is located on the center face of the roadway; and S5, the first arm is controlled to stretch till the anchor net is buckled to the roadway top plate through the supporting frame. According to the net laying method, the labor intensity of anchor net laying operation is reduced, the net laying operation efficiency is improved, and the net laying quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of downhole anchor protection equipment, in particular to a net laying method based on an anchor net anchor protection operation vehicle. Background technique [0002] During the excavation process of the underground roadway, in order to ensure the safety of the excavation, it is necessary to carry out anchor protection on the excavated roadway in time. In related technologies, the anchor protection of the roadway is mostly anchored and shotcrete support, that is, through the method of bolting and laying nets. Realize the support of the surrounding rock of the roadway, but in the related technology, the mesh laying support is mostly completed by underground workers, the work is labor-intensive, and the support efficiency is low. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the...
