Description

Technical Field

[0001] The present invention relates to the technical field of tunnel side wall construction, and in particular to a tunnel wall moving construction device. Background Technique

[0002] In the segmented pouring process of the main structure of the open cut section of the airport tunnel, after the side wall structure is constructed, the steel replacement support system conversion operation needs to be carried out. The installation of the conversion support at this stage depends on the fastener steel pipe scaffold as a temporary operation platform. However, in actual construction, due to the long tunnel, the scaffold needs to be disassembled and assembled repeatedly. But just the erection of the scaffold alone requires 8 - 10 man-days. Repeated disassembly and assembly, plus normal construction, obviously will be time-consuming and laborious, and significantly extend the process cycle.

[0003] Currently, in response to this problem, mobile brackets are often used. Such mobile brackets often take the form of a tripod. One side is supported on one side wall of the tunnel. There is a workbench above for workers to construct the side wall of the tunnel wall. There are rollers at the bottom to facilitate the movement of the bracket along the tunnel. However, the current mobile brackets can only construct one side of the tunnel wall, need to shuttle back and forth in the tunnel, and the construction height is very limited. Only part of the height can be constructed. If the overall construction of the tunnel wall is carried out, a large amount of adjustment and rework are also required, which is also not conducive to efficient construction. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tunnel wall moving construction device in view of the above deficiencies in the prior art. Through the arched support rod and the construction platform running on the arched support rod, when workers construct, they can construct all positions of the tunnel wall at one time, so as to ensure the one-time completion of the construction of the wall without shuttling back and forth in the tunnel, and improve the construction efficiency.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A tunnel wall moving construction device includes a bottom plate, and a plurality of rollers are evenly arranged on the lower surface of the bottom plate. An upper surface of the bottom plate is provided with two arch-shaped support rods with openings downward. On opposite surfaces of the two arch-shaped support rods, a chute is respectively opened along the length direction. The openings of the two chutes face each other. Each chute is connected with a slider, and the two sliders are respectively connected to the left and right sides of a support plate. A rope is respectively connected to the front and rear sides of the support plate. One end of each rope is connected to the support plate, and the other end of each rope is respectively connected to a reel. Each reel is controlled by a clutch driver to wind and unwind the rope. The two reels are respectively located at the joints of the two ends of the arch-shaped support rod and the bottom plate. A workbench plate is arranged on the upper surface of the support plate, and the workbench plate is connected to the support plate through a balance mechanism, and the workbench plate always remains horizontal.

[0006] Further, the balance mechanism includes a fixed hemispherical shell and a balanced hemispherical shell. The balanced hemispherical shell is sleeved inside the fixed hemispherical shell.

[0007] The fixed hemispherical shell is fixed on the upper surface of the support plate and has an opening upward. On the left and right sides of the upper edge of the fixed hemispherical shell, a damping rotating shaft in the horizontal direction is respectively arranged.

[0008] On the left and right side surfaces of the upper end of the balanced hemispherical shell, a groove is respectively opened. A damping bearing is arranged in the groove, and the damping bearing is connected to the damping rotating shaft. The workbench plate is arranged inside the balanced hemispherical shell, and the opening of the balanced hemispherical shell is upward.

[0009] Furthermore, a hydraulic lifter is arranged at the bottom of the balanced hemispherical shell. The lifting end of the hydraulic lifter is connected to the bottom surface of the workbench plate, and the area of the workbench plate is adjustable.

[0010] Furthermore, the workbench plate includes a central plate. The bottom surface of the central plate is connected to the lifting end of the hydraulic lifter. On each side surface of the central plate, at least two telescopic rods in the horizontal direction with adjustable length and limit are respectively arranged. A cushion plate is used to be laid above the telescopic rods, and the edge of the cushion plate facing the central plate is in contact with the central plate.

[0011] Furthermore, support blocks with a stepped surface distribution are also arranged inside the balanced hemispherical shell, and the support blocks are arranged around the inside of the balanced hemispherical shell.

[0012] Further, on the opposite faces of the two arched support rods, a plurality of cross bars connecting the two arched support rods are sequentially arranged along their lengths. The plurality of cross bars are evenly distributed and located below the support plate. The gap between two adjacent cross bars is smaller than the length of the support plate, and the rope is located above the cross bars.

[0013] Furthermore, a first ball is provided on the top of the cross bar.

[0014] Furthermore, a second ball is provided on the bottom surface of the support plate, and the second ball can be in contact with the first ball.

[0015] The present invention has the following advantages compared with the prior art:

[0016] The present invention provides a tunnel wall moving construction device. By arranging arched support rods on the bottom plate and a working table plate for the two arched support rods to move on, due to the action of the fixed hemispherical shell and the balanced hemispherical shell, the working table plate always maintains a horizontal state, enabling workers to keep horizontal during construction. And under the action of the arched support rods, various positions of the tunnel wall can be constructed at one time. Combined with the rollers under the bottom plate, the construction device can be easily moved, thus ensuring the one-time completion of the construction of the tunnel wall without shuttling back and forth in the tunnel, improving the construction efficiency.

[0024] As Figures 1-4 shown, a tunnel wall moving construction device provided by the present invention includes a bottom plate 10. A plurality of rollers 6 are evenly arranged on the lower surface of the bottom plate 10. Two arch-shaped support rods 5 with downward openings are arranged on the upper surface of the bottom plate 10. A chute 14 is respectively opened on the opposite surfaces of the two arch-shaped support rods 5 along the length direction. The openings of the two chutes 14 face each other. Each chute 14 is connected with a slide block 15. The two slide blocks 15 are respectively connected to the left and right sides of the support plate 4. A rope 7 is respectively connected to the front and rear sides of the support plate 4. One end of each rope 7 is connected to the support plate 4, and the other end of each rope 7 is respectively connected to a reel 8. Each reel 8 is respectively controlled by a clutch driver 9 to wind and unwind the rope 7. The two reels 8 are respectively located at the joints of the two ends of the arch-shaped support rod 5 and the bottom plate 10. A workbench plate 16 is arranged on the upper surface of the support plate 4. The workbench plate 16 is connected to the support plate 4 through a balance mechanism, and the workbench plate 16 always remains horizontal.

[0025] When workers are constructing, place the construction device of the present invention inside the tunnel entrance. The rollers 6 at the bottom of the bottom plate 10 can enable the construction device of the present invention to move back and forth in the depth direction of the tunnel. When workers are constructing, move the construction device of the present invention to an appropriate position, operate the two clutch drivers 9, so that the support plate 4 moves to one side of the arch-shaped support rod 5. Workers get onto the workbench plate 16 on the support plate 4 and start constructing the tunnel wall. During construction, the workers below operate the two clutch drivers 9 to make the two reels 8 contract, thereby controlling the rope 7, and then adjusting the position of the support plate 4 according to the needs of construction to cooperate with the construction personnel. Since the support plate 4 is provided with a balance mechanism, the workbench plate 16 always remains horizontal.

[0026] When workers operate the two clutch drivers 9, we take Figure 1For example, when the support plate 4 needs to move clockwise and the support plate 4 is located on the left side of the arched support rod 5, at this time, the left clutch driver 9 is adjusted to the separated state, the right clutch driver 9 is adjusted to the aggregated state, and the adjustment direction is such that the rope 7 pulls the support plate 4 to rotate clockwise. At this time, the left reel 8 will release the rope 7 according to the state of the rope 7, and the right reel 8 winds up the rope 7, so that the rope 7 pulls the support plate 4 to rotate clockwise. When the support plate 4 reaches the arched support rod 5, an operation of switching the two clutch drivers 9 is performed. At this time, the support plate 4 moves to the right side of the arched support rod 5. At this time, the left clutch driver 9 is adjusted to the aggregated state, and the adjustment direction is such that the rope 7 pulls the support plate 4 to rotate clockwise. The right clutch driver 9 is adjusted to the separated state. At this time, the left reel 8 releases the rope 7, so that the rope 7 pulls the support plate 4 to rotate clockwise, and the right reel 8 will wind up the rope 7 according to the state of the rope 7. The above is the operation process of the two clutch drivers 9 when the support plate 4 rotates clockwise. When the support plate 4 rotates counterclockwise, the process can be adjusted appropriately, and the present invention will not elaborate.

[0027] In the present invention, when the state of the clutch driver 9 is separated, the reel 8 will automatically wind up or release the rope 7 under the action of elastic force, so that the rope 7 on the arched support rod 5 is always in a tightened state.

[0028] In the present invention, the balance mechanism includes a fixed hemispherical shell 3 and a balance hemispherical shell 1, and the balance hemispherical shell 1 is sleeved inside the fixed hemispherical shell 3;

[0029] The fixed hemispherical shell 3 is fixed on the upper surface of the support plate 4 and has an upward opening. On the left and right sides of the upper edge of the fixed hemispherical shell 3, a horizontal damping rotating shaft 2 is respectively arranged;

[0030] On the left and right side surfaces of the upper end of the balance hemispherical shell 1, a groove 17 is respectively opened. A damping bearing is arranged in the groove 17, and the damping bearing is connected to the damping rotating shaft 2. A workbench plate 16 is arranged inside the balance hemispherical shell 1, and the opening of the balance hemispherical shell 1 is upward.

[0031] The present invention uses two hemispherical shells, namely a fixed hemispherical shell 3 and a balanced hemispherical shell 1, to automatically adjust the balance. Under the action of the damping rotating shaft 2 and the damping bearing, only when the worker stands on the workbench plate 16, due to the downward acting force, the balanced hemispherical shell 1 rotates within the fixed hemispherical shell 3, and the opening of the balanced hemispherical shell 1 always faces vertically upward, so as to maintain horizontal, thereby enabling the workbench plate 16 inside to remain horizontal. At the same time, due to the hemispherical shell structure, it can also play a certain role in protecting the guardrail during the construction of the worker.

[0032] Among them, in order to better adapt to the construction and adjust the construction device of the present invention to enable the worker to reach the construction height suitable for workers of various heights, a hydraulic lifter 18 is provided at the bottom of the balanced hemispherical shell 1. The lifting end of the hydraulic lifter 18 is connected to the bottom surface of the workbench plate 16, and the area of the workbench plate 16 is adjustable. The function of the hydraulic lifter 18 is to adjust the height of the workbench plate 16, and the area of the workbench plate 16 is adjustable, so that the workbench plate 16 can be in contact with the inner surface of the balanced hemispherical shell 1 at various heights.

[0033] For the workbench plate 16 with an adjustable area, the present invention provides one of its structures. The workbench plate 16 includes a central plate 16-1. The bottom surface of the central plate 16-1 is connected to the lifting end of the hydraulic lifter 18. At least two horizontally adjustable and limitable telescopic rods 16-2 are respectively provided on each side of the central plate 16-1. A cushion plate 16-3 is laid above the telescopic rod 16-2, and the edge of the cushion plate 16-3 facing the central plate 16-1 is in contact with the central plate 16-1.

[0034] During the construction, the worker adjusts the height of the central plate 16-1 in the workbench plate 16 according to his height. At this time, the worker adjusts the length of the telescopic rods 16-2 on each side of the central plate 16-1 and limits them. At this time, one end of the telescopic rod 16-2 is in contact with the inner surface of the balanced hemispherical shell 1. At this time, the cushion plate 16-3 is laid on the telescopic rod 16-2, and it can be completed to make the workbench plate 16 in contact with the inner surface of the balanced hemispherical shell 1. In the present invention, the number of the cushion plates 16-3 is several, and the shape is not particularly limited. The cushion plate 16-3 can also be laid on the central plate 16-1.

[0035] In order to further lay the backing plate 16-3 more smoothly, a support block 19 with a stepped surface is also arranged inside the balanced hemispherical shell 1, and the support block 19 is arranged around the inside of the balanced hemispherical shell 1. The steps of the stepped shape can carry the telescopic rod 16-2, and the telescopic rod 16-2 is placed on the steps of the support block 19, which can increase the load-bearing on the telescopic rod 16-2, so that the workbench plate 16 is more stable and firm, which is beneficial to the safety of construction.

[0036] In the present invention, in order to make the movement of the support plate 4 smoother and enable the rope 7 to apply a smaller force when pulling the support plate 4, in the present invention, the opposite surfaces of the two arched support rods 5 are optimized. On the opposite surfaces of the two arched support rods 5, a plurality of cross bars 11 connecting the two arched support rods 5 are sequentially arranged along their length directions. The plurality of cross bars 11 are evenly distributed and located below the support plate 4, and the gap between two adjacent cross bars 11 is smaller than the length of the support plate 4. The rope 7 is located above the cross bars 11. In this way, the movement of the rope 7 can be limited, so that the movement of the rope 7 follows the arc direction of the arched support rod 5, so that the pulling force of the rope 7 on the support plate 7 is consistent with the plane where the support plate 7 is located, thereby reducing the power of the clutch actuator 9 and making the pulling of the support plate 4 smoother.

[0037] At the same time, in order to make the pulling of the support plate 4 smoother, a first ball 12 is arranged on the top of the cross bar 11. A second ball 13 is arranged on the bottom surface of the support plate 4, and the second ball 13 can be in contact with the first ball 12.

[0038] The present invention provides a tunnel wall moving construction device. By arranging arched support rods 5 on the bottom plate 10 and a workbench plate 16 that moves on the two arched support rods 5, due to the action of the fixed hemispherical shell 3 and the balanced hemispherical shell 1, the workbench plate 16 always maintains a horizontal state, so that workers can keep horizontal during construction. And under the action of the arched support rods 5, it is possible to construct each position of the tunnel wall at one time. Combined with the rollers 6 under the bottom plate 10, the construction device can be easily moved, so as to ensure the one-time completion of the construction of the tunnel wall without shuttling back and forth in the tunnel, improving the construction efficiency.

[0039] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
