Description

Technical Field

[0002] During the construction of ballastless tracks, a ballastless track intelligent rough laying machine is required to assist in laying materials such as track slabs.

[0003] The construction process in the prior art is as follows: The track slab is transported to the storage area by road, and a single-hook gantry crane is used for lateral movement and lowering operations. Workers need to first install the track slab lifting lugs and align the lifting direction, lift to a safe height and then move laterally. The track slab passes through the inner space of the gantry crane, and the direction is manually controlled and lowered to a safe position. Workers insert portal-shaped steel bars and pads, lift the gantry crane, move laterally to the slab-lowering position, execute the lowering command, lower until it contacts the pads, remove the lifting ropes and lugs, and prepare for the lifting of the next track slab. In this process, workers need to manually disassemble and install the track slab lifting lugs, which is time-consuming and laborious. During the lifting process of the track slab using a single-hook gantry crane, the swing is unstable. At the same time, the positioning accuracy during slab lowering is not high, the slab angle cannot be adjusted, and it is difficult to construct after the installation of catenary poles and cable brackets due to the excessive height of the traditional gantry crane, affecting the practicality of the device.

[0033] Working principle:

[0034] Operate the remote control to horizontally move the transverse movement device, that is, start the driving device 26 to drive the driving gear 25 to rotate, thereby driving the rack 24 to move, and finally realizing the movement of the extension frame 9 on the main beam 1; when the transverse movement device moves to the outside position of the vehicle frame and needs to exceed the safety distance from the beam side, then remotely control the driving of the hoisting and traveling device 22 to drive the tray 19 to move on the end beam 21 until the hoisting assembly is moved to the side plate storage area. Then start the hoisting mechanism 20 to lower the hanging bracket 7 to realize the loading and unloading of the plate. After loading and unloading, lift the hanging bracket 7, start the driving device 26 to drive the extension frame 9 to reset. Then start the hoisting mechanism 20 to drive the hanging bracket 7 to descend to the walking safety height. Then drive the walking assembly 5 to drive the device to move. Then drive the hoisting and traveling device 22 to drive the tray 19 to move on the end beam 21 until the hanging bracket 7 is moved to the position above the rough laying point. Then start the hoisting mechanism 20 to lower the hanging bracket 7. The construction worker horizontally rotates the locking rod 37 to drive the rotating block 40 to rotate, thereby realizing the rotation of the supporting pawl 32 and realizing the unloading of the material. Finally, recycle, raise the hanging bracket 7 and move it to the initial position to wait for the next hoisting.
