Beneficial effects:

In the present invention, through the work of the lifting mechanism, the trolley frame, the bracket assembly on the trolley frame and the pressure steel pipe on the bracket assembly can all be adjusted in the height direction synchronously; through the cooperation of the rollers and the track The trolley frame, the bracket assembly on the trolley frame and the pressure steel pipe on the bracket assembly can all move horizontally along the track; at the same time, the work of the translation mechanism makes the pressure on the bracket assembly and bracket assembly The steel pipe can move horizontally in other directions; thus the operator can directly send the pressure steel pipe on the bracket assembly to the installation position of the steel pipe by adjusting the position of the trolley frame on the track, adjusting the lifting mechanism and adjusting the translation mechanism; no need By setting up multiple unloading points, there is no need to set up sky anchors, unloading winches and related equipment, thus making the construction cost lower; at the same time, there is no need to manually operate jacks to deliver the pressure steel pipes to the installation location, making the construction risk smaller; and mechanized Operation also makes construction more efficient.

In the present invention, since the lifting device is connected to the trolley frame, when the present invention is in the lifted state, the roller body is no longer in contact with the track, so that the trolley frame does not move along the track, so that the present invention sends the pressure steel pipe to The process of installing the location is safer.

In the present invention, the length direction of the side beam corresponds to the installation direction of the track, and the side beam is above the track when the trolley frame moves. Therefore, the rollers are arranged on the side beam to facilitate the cooperation between the roller and the track. The lifting device is arranged on the side beam to facilitate the lifting movable part to contact the track; at the same time, compared with the ground of the tunnel, the surface of the track is smoother, so the lifting movable part can contact the track more stably, lifting the trolley Stability when the frame is raised.

In the present invention, the bracket supports at both ends of the bracket body are slidingly matched with the side beams on both sides of the trolley frame, so that the direction in which the bracket assembly moves under the action of the translation mechanism is consistent with the movement of the trolley frame on the track. The movement directions on the bracket assembly are different; thus, the pressure steel pipe on the bracket assembly can be adjusted in multiple directions to adapt to different installation environments.

In the present invention, through the arrangement of the matching groove, the lifting movable part can contact the track more stably, thereby improving the stability of the trolley frame when it is lifted.

In the present invention, the bracket support and the side beam achieve sliding fit through the cooperation of the sliding groove and the sliding rail; at the same time, the sliding groove and the sliding rail are in the shape of a dovetail groove, and the shape restriction makes the sliding groove and the sliding rail in After the matching is completed, it will be closer, more stable and less likely to fall off; making the use of the present invention safer.

In the present invention, since the length of the steering shaft is greater than the length of the through hole, when the lifting mechanism lifts the trolley frame and the roller body is no longer in contact with the track, the left roller and the right roller will sag under the action of gravity. And the roller support is not in contact with the left and right beams; after the lifting mechanism is reset, the trolley frame falls back to its original position, the roller body is in contact with the track again, and the roller support is in contact with the left and right beams again; and then through The cooperation of the limit groove and the limit block prevents the roller support from being dislocated when it is reset, and makes the roller support more closely cooperate with the left and right beams.

In the present invention, the control system controls the steering movable part of the steering adjustment device, thereby making the adjustment of the steering movable part more convenient and faster, thereby making the use of the present invention more convenient and thereby improving the use efficiency of the present invention.

In the present invention, both ends of the steering pin are rotatably connected to the roller support and the other end of the movable connecting rod respectively; thus, the force acting on the straight line when the steering movable part expands and contracts is converted into a force that regulates and supports the rotation of the roller support, Then adjust the direction of the left and right rollers.

In the present invention, when the left roller and the right roller are adjusted to a certain angle, the work of the steering adjustment device can be limited by the travel limit switch to avoid over-adjustment as much as possible.

In the present invention, the steering adjustment device adopts a double-acting hydraulic cylinder, so that the present invention can provide a double-acting hydraulic cylinder to exert an adjusting force on the two left rollers and the two right rollers; compared to setting the hydraulic cylinder according to the number of rollers In this way, the present invention reduces production costs; moreover, the double-acting hydraulic cylinder can also apply adjustment force to the two left rollers and the two right rollers at the same time, speeding up the adjustment speed of the left roller and the right roller, and improving the construction efficiency.

Start the hydraulic pump station and control the lifting mechanism to lift the entire trolley frame. When the roller is 50cm away from the 10th surface of the track, the lifting operation is stopped. After the roller is turned to 90°, the roller steering cylinder is stopped. Control the lifting mechanism to lower the trolley as a whole. After the steering roller contacts the track 10, continue to contract the oil cylinder of the lifting mechanism, so that the lifting mechanism lifts the trolley frame to more than 50mm away from the track 10 and then stops. At this point, the trolley frame completes the track 10 After switching, the power supply of the hydraulic pump station is removed, and the trolley frame is towed and moved to the steel pipe installation point.

4) Installation and adjustment steps: The trolley frame is towed and moved to the steel pipe installation point from step 3), and adjusted to the installed steel pipe 86. First, connect the power supply from the mobile power supply panel to the hydraulic pump station, start the hydraulic pump station, and control the lifting mechanism to lift the entire trolley frame so that the horizontal center of the steel pipe on the trolley frame is flush with the steel pipe installation horizontal line, and Control the two sets of lifting cylinders 47 at the front and rear of the trolley frame respectively to adjust the inclination of the steel pipe axis on the trolley to complete the horizontal height adjustment.

The translation cylinder 53 of the transverse translation mechanism on the control trolley frame makes the vertical center of the steel pipe on the trolley frame flush with the vertical center line of the steel pipe installation to complete the vertical center adjustment.

After the steel pipe installation position is adjusted, it is welded and positioned with the 86-inch nozzle of the installed steel pipe. The bottom of the steel pipe is reinforced with steel supports.

5) Return step: Control the lifting mechanism to lower the trolley frame as a whole, make the rollers contact the track 10 and then continue to shrink the oil cylinder. Then, the lifting mechanism will detach the trolley from the track 10 by more than 50mm and then stop the lifting work. Turn on the power of the hydraulic pump station. Remove and pull the trolley frame to the steel pipe loading and unloading point 84.
