Embodiment 1
[0029] A set-out device for road and bridge construction, comprising a protection box 1, a laser transmitter 7 is arranged on the protection box 1, a paint box 8, a storage battery 6 and a console 5 are arranged on the side of the laser transmitter 7, and the paint box 8 passes through the liquid guide The tube 9 is connected to the nozzle 11, the catheter tube 9 is provided with a solenoid valve 10, the console 5 is electrically connected to the battery 6, the laser transmitter 7 and the solenoid valve 10 through wires, and the protection box 1 is provided with an upper magnet with the same magnetic properties. Plate 21 and lower magnet plate 22, upper magnet plate 21 and lower magnet plate 22 are all horizontally arranged, upper magnet plate 21 is fixed on the top of protection case 1, and lower magnet plate 22 is located at the bottom of protection case 1, and upper magnet plate 21 and lower magnet A telescopic tube 4 is vertically fixedly connected between the plates 22 , a...
Embodiment 2
[0035] The using method of a kind of road and bridge construction setting-out device in embodiment 1:
[0036] Pigment liquid is packed in the paint box 8.
[0037] By handle 15, wheel 13 is moved to the starting position along the sideline of the road, laser emitter 7 is opened, and alignment is carried out by laser emitter 7, so that the light beam emitted by laser emitter 7 is consistent with the markers set on the sideline of the road on the same straight line.
[0038] Push the handle 15 to make the wheels 13 move forward at a constant speed, and at the same time energize the normally closed solenoid valve 10 on the console 5. After the power is turned on, the electromagnetic coil generates magnetic force, pulls the moving iron core and attracts the static iron core, and directly opens the valve port , the paint liquid flows to the liquid outlet through the valve port, and finally the paint liquid is evenly sprayed and marked on the ground through the nozzle 11;
