Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 5 and Figure 10 , a tunnel arch installation device shown in the figure, including a track slab 1, the track slab 1 is laid flat in the tunnel, and further includes a moving frame 2. A conveying part 3 adapted to the track slab 1 is installed at the bottom of the moving frame 2. Two lead screws 4 are rotatably installed in the moving frame 2. A lifting part 5 is threadedly sleeved on the outer sides of the two lead screws 4, and the arch part is driven to move upward through the lifting part 5; and a driving mechanism 6 installed on the moving frame 2, which drives the two lead screws 4 to rotate synchronously through the driving mechanism 6; and a docking plate 7, the docking plate 7 is docked with the arch foot, and a locking part 8 inserted into the end slot of the arch foot is installed on the docking plate 7. A through hole 9 is opened on the docking plate 7, and a docking mechanism 10 is installed on the lifting part 5, and the docking mechanism 10 is docked with the through hole 9 on the docking plate 7;

[0031] In this solution, the designed conveying part 3 drives the moving frame 2 to move back and forth in the tunnel along the track slab 1. After driving the arch part to near the two arch feet, the lifting part 5 is used to drive the arch part to move upward. After moving upward to the designated position, the docking mechanism 10 operates to align the two ends of the arch part with the arch feet, simulating that personnel lift the arch part to adjust the position to align the arch part with the arch feet. Thus, when lifting and aligning the arch part, it is faster and more accurate, without the need for personnel to climb high to lift the arch part in person, reducing risks and improving the safety of personnel during operation;

[0032] It should be noted that: the track slab 1 in this solution is laid in the tunnel, and only the area that needs to be laid in the tunnel needs to be leveled, without the need to process all areas. At the same time, the track slab 1 can be spliced to meet the long-distance movement of the moving frame 2 in the tunnel, facilitating the lifting and installation of multiple arch parts.

[0033] It also should be noted that a counterweight frame 45 is provided on the moving frame 2. When lifting the arch part, in order to avoid too high overall center of gravity, causing the arch part to tilt and affect the installation, personnel can place counterweight blocks on the counterweight frame 45.

[0034] Further, referring to Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , the lifting part 5 includes a lifting seat 11 threadedly docked with the lead screw 4. A lifting plate 12 is fixed between the two lifting seats 11. Arc-shaped seats 13 are fixed at both ends of the lifting plate 12. The arc-shaped seats 13 are in contact with the arch part. A jacking unit 14 for jacking up the arch part is installed on the lifting plate 12;

[0035] Among them, side plates 15 are fixed on the arc-shaped seats 13. The distance between the two side plates 15 is greater than the width of the arch part. A chamfer for the outer wall of the arch part to fit with the arc-shaped seat 13 is provided at the docking position of the side plate 15 and the arc-shaped seat 13.

[0036] At the same time, referring to Figure 3 and Figure 5 , the driving mechanism 6 includes a driving motor 35 fixed to the top of the moving frame 2 through a motor bracket. Two driving wheels 36 are rotatably installed on the top of the moving frame 2. The output end of the driving motor 35 is fixed to one of the driving wheels 36 through a coupling. A first synchronous belt 37 is meshed and sleeved between the two driving wheels 36. A transmission wheel 38 meshed with the driving wheel 36 is fixed to the top of the lead screw 4. Two sliding rods 39 are fixed at both ends of the moving frame 2. The two sliding rods 39 are respectively in sliding docking with the two lifting seats 11.

[0037] The principle of the lifting part 5 driving the arch part to move upward: first, the personnel places the arch part on the two arc-shaped seats 13, and then provides power through the driving motor 35 to rotate the driving wheel 36, and cooperates with the synchronous belt 37 to make the two driving wheels 36 rotate synchronously, so that the transmission wheel 38 meshing with them rotates synchronously, and the two screw rods 4 rotate synchronously, thereby driving the lifting seat 11 and the lifting plate 12 to move upward synchronously, and moving the arch part placed on the arc-shaped seat 13 upward.

[0038] It should be noted that, in order to facilitate accurate placement of the arch, side plates 15 are fixed on both sides of the arc seat 13, and the chamfers in the side plates 15 can help the arch to be stably located at the center of the arc seat 13 during the lifting process.

[0039] For further information, see Figure 7 and Figure 8 The lifting unit 14 includes a lifting disk 16, the top of the lifting disk 16 is a spherical structure, a threaded rod 17 is fixed to the bottom of the lifting disk 16, the threaded rod 17 is slidably plugged with the lifting plate 12, an adjusting cylinder 18 threadedly sleeved with the threaded rod 17 is rotatably installed at the bottom of the lifting plate 12, a gear ring 19 is fixed to the outside of the adjusting cylinder 18, a lifting motor 20 is fixed to the bottom of the lifting plate 12, a lifting gear 21 meshing with the gear ring 19 is fixed to the output end of the lifting motor 20, a limiting opening 22 is provided on the outside of the threaded rod 17, and a limiting block 23 slidably docked with the limiting opening 22 is fixed on the lifting plate 12;

[0040] Among them, see Figure 8 - Figure 10 The docking mechanism 10 includes two turntables 24 rotatably mounted at the bottom of the lifting plate 12. Two docking motors 25 are fixed to the bottom of the lifting plate 12 through a motor frame. The output ends of the two docking motors 25 are fixed to the rotating shafts of the turntables 24. A docking rope 26 is fixedly wound inside the turntable 24. The outer end of the docking rope 26 slides through the through hole 9 and is fixed with a threaded end 27. The outer side of the threaded end 27 is threadedly inserted with a counter cap 28.

[0041] Principle of aligning the arch part with the arch feet using the docking mechanism 10: First, the operator passes the threaded end 27 at the outer end of the docking rope 26 through the through hole 9 first, and then through the control part at one end of the arch part. Subsequently, the abutting cap 28 is screwed on. Immediately afterwards, the operator fits the docking plate 7 with one end of the arch foot, and uses the locking part 8 to achieve docking and fixing with the slot of the arch foot. Then, the arch part is moved so that the arch part moves between the two arch feet. Finally, driven by the jacking motor 20, the jacking gear 21 rotates, driving the toothed ring 19 and the adjusting cylinder 18 to rotate, so that the threaded rod 17 and the jacking disc 16 move upward, causing the arch part to move upward. Subsequently, the docking motor 25 drives the turntable 24 to rotate, causing the docking rope 26 to wind and tighten, so that the abutting cap 28 is pulled, gradually approaching the docking plate 7, and finally the arch part and the arch foot will be in contact with each other to complete the alignment, and it is easy for the operator to insert bolts;

[0042] It should be noted that when the arch part is jacked up by the jacking disc 16, the top of the jacking disc 16 is a spherical structure. When the docking mechanism 10 adjusts the angle of the arch part, the arch part turns more easily, which can replace the operation of regularly moving the arch part by the operator;

[0043] It also should be noted that when the arch part is jacked up by the jacking disc 16, the arch part is separated from the outside of the arc-shaped seat 13. At the same time, the arch part is between the two side plates 15. The two side plates 15 can prevent the arch part from falling. The distance between the two side plates 15 is greater than the width of the arch part, meeting the angle adjustment of the arch part within a certain range and facilitating the alignment of the arch part with the arch feet.

[0044] In this solution, the process of docking and installing the arch part and the arch feet in the arch support includes the following steps:

[0045] The first step is that the operator first lays the track slab 1 in the tunnel so that the moving frame 2 can move along the track slab 1;

[0046] The second step is to install two arch feet in the tunnel;

[0047] The third step is to place the arch part on the arc-shaped seat 13. Powered by the driving mechanism 6, the lifting seat 11 drives the arch part to move upward. Cooperating with the movement of the moving frame 2 along the track slab 1, the arch part is sent between the two arch feet;

[0048] The fourth step is that the operator installs the docking plate 7 on the arch foot, and passes the docking rope 26 through the through hole 9 and the slot on the arch part in sequence, and uses the abutting cap 28 to abut against the arch part;

[0049] The fifth step is to drive the arch part to continue to move upward through the jacking unit 14 and separate it from the contact with the arc-shaped seat 13;

[0050] In the sixth step, the docking motor 25 inside the docking mechanism 10 rotates, causing the docking rope 26 to be pulled, so that the arch and the arch feet gradually approach and align with each other;

[0051] In the seventh step, the slots on the arch and the arch feet are docked using bolts. Subsequently, the docking plate 7 and the docking rope 26 are removed, and bolts are installed;

[0052] In the eighth step, the moving frame 2 retreats, and the lifting seat 11 moves downward to start the next round of docking of the arch and the arch feet.

[0053] In this solution, the lifting part 5 and the conveying part 3 are used to lift and convey the arch to the arch feet. After the simulated personnel lift the arch, with the help of the docking mechanism 10, the arch and the arch feet gradually approach and align with each other. After the simulated personnel lift the arch, the arch is manually adjusted, so that construction workers do not need to climb to lift the arch, the operation is safer, and at the same time, the two ends of the arch can be aligned with the arch feet quickly and accurately, facilitating the insertion of bolts.

[0054] Embodiment 2: Please refer to Figure 9 and Figure 10 This embodiment further illustrates Embodiment 1, and the difference lies in disclosing a specific implementation manner of the locking member 8.

[0055] Specifically, the locking member 8 includes a threaded cylinder 29 fixed on the docking plate 7. The outer end of the threaded cylinder 29 is fixed with a rubber tube 30. An adjusting rod 31 is threadedly inserted into the threaded cylinder 29. One end of the adjusting rod 31 is fixed with a rotating cap, and the other end is fixed with an adjusting ball 32 that abuts against the rubber tube 30. An adjusting ring 33 adapted to the adjusting ball 32 is fixed on the inner wall of the rubber tube 30;

[0056] In this solution, when installing the docking plate 7, the non-compressed rubber tube 30 is first inserted into the slot of the arch foot, and then the adjusting rod 31 is rotated. When the adjusting rod 31 moves, it will squeeze the air pressure inside the threaded cylinder 29, causing the rubber tube 30 to expand. At the same time, the adjusting ball 32 will move with the adjusting rod 31 and squeeze the adjusting ring 33, making the rubber tube 30 abut against the inner wall of the slot, ensuring the installation stability of the docking plate 7. At the same time, a chamfer is provided on the outside of the through hole 9 of the docking plate 7. After the subsequent docking rope 26 passes through, when the docking rope 26 is pulled, the docking rope 26 can move more smoothly.

[0057] It should be noted that in order to increase the fitting range between the docking plate 7 and the arch foot and make the docking between the docking plate 7 and the arch foot stable, a fitting plate 34 that fits against the outside of the arch foot is fixed on the docking plate 7.

[0058] Embodiment 3: Please refer to Figure 3 and Figure 6, this embodiment further illustrates other embodiments, and the difference lies in disclosing a specific implementation manner of the conveying part 3.

[0059] Specifically, the conveying part 3 includes a plurality of conveying wheels 40 rotatably docked with the bottom of the moving frame 2. The conveying wheels 40 move along the track plate 1. A conveying motor 41 is fixed on the moving frame 2 through a motor bracket. Conveying gears 42 are fixed on the output end of the conveying motor 41 and on a plurality of conveying wheels 40. A second synchronous belt 43 is sleeved on the outside of the plurality of conveying gears 42 in a meshing manner. A tight belt column 44 that fits with the second synchronous belt 43 is fixed to the bottom of the moving frame 2. The tight belt column 44 can make the second synchronous belt 43 stably mesh with the conveying gears 42 to avoid slipping.

[0060] In this solution, when the conveying motor 41 rotates, it drives one of the conveying gears 42 to rotate. Under the action of the second synchronous belt 43, a plurality of conveying wheels 40 rotate synchronously, thereby driving the moving frame 2 to move along the track plate 1.

[0061] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
