Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction, and more specifically, particularly relates to a tunnel laser engraving and laying-out device. Background Art
[0002] When tunnel excavation and pipeline and fire-fighting facility installation are required after excavation, it is necessary to first determine the installation position in the tunnel. The installation position is usually determined by measuring and then marking with manual ink box lines, so that the equipment can be installed according to the marked position in the later stage. However, the track plane of the subway tunnel is an inclined plane rather than a horizontal plane at the bend, and most of the equipment installed in the tunnel uses the horizontal plane of the track as a reference height, which will cause the problem of inaccurate defense line position. In addition, manual ink box lines will occasionally cause occasional errors due to human error. Moreover, the ink line has the defect of easy wear, which increases the frequency of repeated line laying in the later stage. Therefore, the utility model aims to provide a tunnel laser engraving line laying device with high line laying accuracy and not easy to wear after the defense line. Utility Model Content
[0003] The utility model is to overcome the above-mentioned shortcomings and aims to provide a tunnel laser engraving laying-out device which can solve the above-mentioned problems and has high laying-out accuracy and is not easy to wear behind the line.
[0004] A tunnel laser engraving laying-out device comprises a rail trolley, a support frame is arranged on the rail trolley, a laser engraving mechanism is installed on the support frame, a height adjustment mechanism is arranged on the rail trolley for supporting the support frame and adjusting the height of the support frame, and a mobile power supply for powering the laser engraving mechanism is also arranged on the rail trolley.
[0005] Furthermore, the support frame includes two parallel beams and a support plate slidably arranged between the two beams, the beams are perpendicular to the tracks in the tunnel, and both ends of the beams are connected to the height adjustment mechanism, and the laser engraving mechanism is installed on the support plate.
[0006] Furthermore, a through slot is horizontally opened on the cross beam, and locking bolts are arranged at both ends of the support plate. The locking bolts pass through the through slot and are threadedly connected to the support plate.
[0007] Furthermore, a fixed plate is fixed on the crossbeam, and a rotating plate is rotatably connected to the upper end surface of the fixed plate. The laser engraving mechanism is installed on the rotating plate. Two clamping blocks are symmetrically and telescopically arranged on the bottom of the rotating plate. A groove matching the clamping block is opened on the fixed plate, and the connecting line of the two grooves is parallel to the crossbeam.
[0008] Furthermore, a receiving groove is vertically opened on the lower end surface of the rotating disk, and a spring is arranged in the receiving groove. The clamping block is arranged in the receiving groove by the spring, and the lower surface of the clamping block is arc-shaped.
[0009] Furthermore, the height adjustment mechanism includes four adjustment screws vertically fixed on the rail trolley and adjustment knobs rotatably arranged at both ends of the beam, and the adjustment knobs are rotatably sleeved on the adjustment screws.
[0010] Furthermore, circular rings are fixed at both ends of the crossbeam, and the adjusting knob is cylindrical and the outer side is rotatably connected to the circular ring through a bearing.
[0011] Furthermore, the rail trolley includes a base plate and rail wheels arranged at the four corners of the base plate.
[0012] Furthermore, the rail trolley is also provided with a travel drive mechanism, which includes a travel motor arranged above the base plate, a driving wheel drivingly connected to the travel motor, a driven wheel arranged on the outside of the rail wheel and fixed to the wheel axle, and a belt drivingly connected to the driving wheel and the driven wheel.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The tunnel laser engraving and laying-out device in this embodiment is provided with a track trolley, which relies on the track plane in the tunnel. When the track is an inclined surface, the track trolley is correspondingly inclined, so that the laser engraving mechanism installed on the track trolley is inclined, so that the laying-out height is consistent with the defense line height when the track is flat, solving the problem of inaccurate laying-out at the inclined surface of the track.
[0015] By setting up a height adjustment mechanism, the height of the support frame and the laser engraving mechanism can be adjusted, so that wire laying can be carried out for equipment with different installation heights. In addition, since a track trolley is set up, there is no need to measure the height multiple times. The height can be adjusted once for batch laying, which saves labor. The use of a track trolley as a carrier significantly improves the wire laying speed.
[0016] This device adopts laser engraving and laying out, which can solve the occasional errors in manual ink cartridge marking and the easy wear of ink line, and reduces the workload and work intensity of reviewing and laying out. BRIEF DESCRIPTION OF THE DRAWINGS
