Detailed Description

The following detailed description of the present invention is provided with reference to the accompanying drawings and examples, but not to be construed as limiting the present invention in any way.

As shown in figure 1, an automatic track laying device of a lining trolley, a trolley portal frame 12 of the lining trolley moves along a corresponding track 7 through a connected traveling system component 10, the track 7 is an I-shaped steel track and consists of an upper supporting plate, a lower supporting plate and a web plate, the upper supporting plate and the lower supporting plate are horizontally arranged, and the web plate is arranged along the vertical direction and is connected with the upper supporting plate and the lower supporting plate at two ends respectively. The lining trolley runs along two parallel rails 7 during operation, and two sets of traveling system assemblies 10 are arranged on each side of the lining trolley and move along the same rail 7. Lining cutting platform truck and traveling system subassembly 10 belong to tunnel construction field conventional equipment.

With continued reference to fig. 1 and 2, the trolley gantry 12 is connected to the traveling system assembly 10 through a lift cylinder 16, a support leg 15 is arranged on the trolley gantry, when the lift cylinder 16 descends, the support leg 15 descends along with the cylinder and supports on the ground, the lift cylinder 16 descends continuously, the support leg 15 jacks up the traveling system assembly 10, and the traveling system assembly 10 is provided with a lifting mechanism which lifts up along with the traveling system assembly 10 and lifts the rail 7 off the ground.

The lifting mechanism comprises an outer sleeve 2 fixedly arranged on the traveling system component 10, an inner sleeve 13 is sleeved in the outer sleeve 2, the inner sleeve 13 is connected with the outer sleeve 2 through a bolt 1, the lower end of the inner sleeve 13 is exposed out of the outer sleeve 2, a bolt head of the bolt 1 is positioned in the inner sleeve 13, the other end of the bolt 1 penetrates through the inner sleeve 13 and the outer sleeve 2 upwards and is connected with a nut in a matched mode, and the upper position and the lower position of the inner sleeve 13 in the outer sleeve 2 can be adjusted through rotating the nut. The lower part of the inner sleeve 13 is provided with two branches respectively positioned at two sides of the track 7, a mandrel 3 is fixedly installed on each branch to serve as a supporting body, the axial direction of the mandrel 3 is perpendicular to the web plate of the track 7, a certain distance is kept between the shaft end of the inner side of the mandrel 3 and the track 7, when the walking system component 10 is jacked up, the mandrel 3 moves upwards to be in contact with the upper supporting plate of the track 7, and then the track 7 is lifted off the ground.

Furthermore, two mandrels 3 are arranged on the branch of the inner sleeve 13 on the same side of the track 7 so as to improve the bearing capacity of the track 7.

The support body may have other structures than the mandrel 3 as long as it can support the lower surface of the support plate on the rail 7 to lift the rail 7. Furthermore, the support body may be provided with a freely rotatable rolling portion to convert the sliding friction into a smaller rolling friction when the subsequent rail 7 is moved forward.

After the rail 7 is lifted, an external force is also applied to the rail 7 to push the rail 7 to move to a next station. Therefore, the utility model discloses the side-mounting drive mechanism of overcoat 2, drive mechanism pull track 7 through the haulage rope and go forward. The traction mechanism is arranged on the rear walking system component 10 of the two walking system components 10 on each track 7, and the traction rope pulls the track 7 forward to drive the track 7 to move forward.

As shown in fig. 2, the traction mechanism includes a traction motor 4 as a power source and a traction rope winding mechanism driven by the traction motor 4 to rotate, the traction rope may be a steel wire rope 11 or a chain, and in this embodiment, the steel wire rope 11 is used. Most of the wire rope 11 is wound on the traction rope winding mechanism, and the end part of the wire rope 11 is fixed on the ear plate seat 5 arranged on the track 7. In practical use, a winch can be used as the traction mechanism.

In the process that the traction mechanism 4 pulls the track 7 to advance, in order to reduce friction between the track 7 and supporting bodies such as the mandrel 3, tugs 6 can be installed at two ends of the track 7, and the tugs 6 are supported on the ground to drive the track 7 to advance. The tug 6 rotates and installs on a mount pad, the mount pad rotates through the round pin axle and installs the tip at track 7, after track 7 fell subaerial, the mount pad rotates the side to track 7 tip, be horizontal state, after track 7 is lifted up, the mount pad is rotatory 90 to vertical state, tug 6 supports subaerial this moment, prop up track 7, track 7 is for greatly reducing to dabber 3's pressure, even track 7 can be with dabber 3 contactless, further reduction track 7 frictional force that advances.

For the track 7 with a shorter length, after the track 7 is lifted, both ends of the track 7 can be lifted to the same height, and the tug 6 can normally rotate to the vertical position. However, for the rail 7 having a large length, when the rail 7 is lifted, both ends thereof may not be completely lifted even away from the ground, so that it is difficult to rotate the tug 6 to the vertical position to support the rail. In order to solve the problem, the utility model discloses the rigidity that is close to 7 tip of track is further again set up a jacking seat 8, and jacking seat 8 is located track 7's side, has horizontally jacking face, and the lower surface of jacking face is the stress surface of jack, and the jack just can be in place the rotation of tow boat 6 with support track 7 with 7 tip jack-up backs on jacking seat 8 like this, remove the jack at last can.

The utility model discloses realize orbital automatic process of laying as follows: firstly, the lifting oil cylinder 16 of the trolley gantry 12 drives the supporting legs 15 to descend, after the supporting legs 15 are supported on the ground, the lifting oil cylinder 16 continues to descend, and then the walking system component 10 is lifted, so that the lifting mechanism connected with the walking system component 10 lifts the track 7 off the ground; secondly, the mounting seat of the tug 6 is rotated downwards by 90 degrees, so that the tug 6 is supported on the ground; and thirdly, starting the traction motor 4, pulling the steel wire rope 11, and dragging the rail 7 to advance to the next station by the steel wire rope 11.

If the track 7 is longer, can't keep the horizontality at track 7 both ends, can put hydraulic jack 9 in the below of jacking seat 8, jack-up jacking seat 8 adjusts the height of track 7 tip, rotates tow boat 6 in place again and carries out subsequent track and pull.

The above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and it should be understood by those of ordinary skill in the art that the embodiments of the present invention can be modified or replaced with equivalents with reference to the above embodiments, and any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are all within the scope of the claims of the present application.
