It is placed at one end of the folding rod 41 away from the anchor rod propulsion system 3, and a first rotation damper (not shown in the figure) is arranged between the lighting assembly 44 and the folding rod 41, so that the lighting assembly 44 can remain stable after being rotated to a specific position relative to the folding rod 41; the first driving assembly 43 is a linear motor in the prior art, and the first driving assembly 43 is fixedly arranged on one side of the anchor rod propulsion system 3, one end of the push-pull rod 42 is hinged to the output end of the first driving assembly 43 through a preset hinge shaft, and the other end of the push-pull rod 42 is hinged to the middle position of the folding rod 41 through a preset hinge shaft.

[0024] When in use, the first drive assembly 43 outputs in a forward direction, causing the push-pull rod 42 to push the folding rod 41 to unfold, thereby allowing the lighting assembly 44 to face the construction position to achieve the lighting function; when idle, the first drive assembly 43 outputs in a reverse direction, causing the push-pull rod 42 to pull the folding rod 41 to retract, thereby allowing the lighting assembly 44 to retract to one side of the anchor rod propulsion system 3, thereby reducing the space occupied by the lighting system 4.

[0025] In this embodiment, the anchor trolley also includes a distance measuring system 5, which is arranged on the anchor propulsion system 3; the distance measuring system 5 specifically includes an arc-shaped slide rail 51, an arc-shaped slider 52, a second drive component 53 and an infrared component 54; wherein, the arc-shaped slide rail 51 is fixedly arranged at the bottom of the anchor propulsion system 3 through a connecting block, and the arc-shaped slide rail 51 and the anchor propulsion system 3 are coaxially arranged, the arc-shaped slider 52 is slidably adapted to the arc-shaped slide rail 51, the arc-shaped slider 52 is slidably arranged on the arc-shaped slide rail 51, the second drive component 53 is connected between the arc-shaped slide rail 51 and the anchor propulsion system 3, and the second drive component 53 is used to drive the arc-shaped slider 52 to slide along the arc-shaped slide rail 51, the infrared component 54 is an infrared irradiation lamp, the infrared component 54 is hingedly arranged on the arc-shaped slider 52 through a preset hinge axis, and a second rotation damper (not shown in the figure) is arranged between the infrared component 54 and the arc-shaped slider 52, so that the infrared component 54 can remain stable after rotating to a specific position relative to the arc-shaped slider 52.

[0026] During the process of drilling the anchor rod of the anchor rod propulsion system 3, the infrared component 54 is rotated to a suitable angle so that the infrared component 54 is aligned with the completed drill hole, thereby positioning the anchor rod of the anchor rod propulsion system 3 and improving the uniformity of the drilling; the second driving component 53 is used to drive the arc-shaped slider 52 to slide along the arc-shaped slide rail 51, which can drive the infrared component 54 to rotate along the anchor rod of the anchor rod propulsion system 3, thereby improving the applicability of the ranging system 5.
