Description

Technical Field

[0001] The invention relates to the field of pipe segment splicing, and in particular to a tunnel pipe segment rapid assembly device. Background Art

[0002] In tunnel construction, segment assembly is a critical step in ensuring tunnel structural stability and construction safety. Its efficiency and quality directly impact the overall project progress and subsequent operational reliability. Currently, traditional segment assembly relies heavily on manual labor or the use of complex, large-scale equipment, resulting in numerous technical challenges.

[0003] Existing equipment often requires multi-step coordination for segment movement and alignment. The clamping mechanism's adjustment accuracy is insufficient, making it difficult to quickly and accurately clamp and align the segments. Consequently, repeated adjustments are often required due to angular deviations and positional shifts during segment movement from storage to installation. This significantly increases the assembly time of single-ring segments and severely restricts construction efficiency. This problem is particularly exacerbated by the cumbersome structure and cumbersome operation of traditional equipment in large-diameter tunnels or complex geological conditions, making it difficult to meet the demands of efficient construction.

[0004] Therefore, those skilled in the art have proposed a rapid assembly device for tunnel segments to solve the problems raised in the above background. Summary of the Invention

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] Example 1: Please refer to Figure 1 A rapid assembly device for tunnel segments includes a moving beam 1 connected to a shield machine, a first motor 2 fixedly connected to the side of the moving beam 1, a first screw 3 fixedly connected to the rotor of the first motor 2, a clamping assembly 4 threadedly connected to the outer side of the first screw 3, the clamping assembly 4 is slidably connected to the moving beam 1, and a synchronously moving transmission assembly 5 is provided under the moving beam 1, and the transmission assembly 5 cooperates with the clamping assembly 4 to move the segment.

[0027] During use, the device moves synchronously with the shield machine, and the rotation of the first motor 2 drives the first screw 3 to rotate. The rotation of the first screw 3 can adjust the position of the clamping component 4 to achieve clamping of the pipe segment. After the clamping component 4 clamps the pipe segment, it can be moved to the conveying component 5 and quickly transferred to the installation position for convenient and quick installation.

[0028] See also Figure 2 The clamping assembly 4 includes a sliding frame 6 threadedly connected to the first screw rod 3, the sliding frame 6 is slidably connected to the moving beam 1, and two electric telescopic rods 7 are symmetrically arranged below the sliding frame 6. The lower ends of the electric telescopic rods 7 are fixedly connected to the moving base plate 8, and the moving base plate 8 is fixedly connected to the mounting frame 9. The top of the mounting frame 9 is fixedly connected to the clamping motor 10, and the rotor of the clamping motor 10 is fixedly connected to the clamping shaft 11. The clamping shaft 11 is rotatably connected to the moving base plate 8, and the bottom of the clamping shaft 11 is fixedly connected to the clamping unit 12.

[0029] The rotation of the first screw 3 drives the carriage 6, which moves in the direction in which the segment is to be transported. This movement direction is controlled by the steering of the first motor 2, facilitating continuous transport operations. The electric telescopic rod 7 moves up and down, allowing the clamping unit 12 to grip the segment. During this movement, the segment must first be lifted to a sufficiently high position to prevent collision with the conveyor assembly 5. Once it reaches above the conveyor assembly 5, it is lowered and placed in the transport position.

[0030] A driving gear 13 is fixedly connected to the outside of the clamping shaft 11. Side shafts 14 are symmetrically connected to the sides of the mounting frame 9. Fan blades 15 are fixedly connected to the bottom of the side shafts 14. The mounting frame 9 is provided with a blowing port that matches the fan blades 15. A driven gear 16 is fixedly connected to the outside of the side shaft 14, and the driven gear 16 is in transmission connection with the driving gear 13. A transmission gear 17 is rotatably connected to the bottom of the mounting frame 9. The driving gear 13 meshes with the transmission gear 17, and the transmission gear 17 meshes with the driven gear 16.

[0031] The rotation of the clamping motor 10 drives the clamping shaft 11, which in turn adjusts the segment's orientation, facilitating subsequent installation in the optimal direction. Drive gears 17 on both sides of the clamping shaft 11 drive the driven gears 16, which in turn rotate the fan blades 15. The fan blades 15 remove dust and impurities from the segment through the air outlet, preventing debris from attaching and affecting installation quality.

[0032] See also Figure 3 The clamping unit 12 includes a connecting top plate 18, and two clamping rods 19 are symmetrically arranged on the left and right sides of the bottom of the connecting top plate 18. The clamping rods 19 on the same side are linked by a linkage rod 20. The outer side of the middle part of the linkage rod 20 is rotatably connected to a ring 21, and the two sides of the connecting top plate 18 are rotatably connected to clamping telescopic rods 22, and the ends of the clamping telescopic rods 22 are fixedly connected to the rings 21.

[0033] The clamping telescopic rod 22 is electrically driven, and during the telescopic process, the clamping rod 19 is driven to swing toward or away from each other through the collar 21. When swinging toward each other, the pipe segment is clamped, and when swinging away from each other, the pipe segment is released.

[0034] Example 2: This example discloses the following technical means based on the previous example: Please refer to Figure 4 The conveying assembly 5 includes a conveying base plate 23, to which two conveying shafts 24 are rotatably connected. Conveying rollers 25 are fixedly connected to the outer sides of the conveying shafts 24. A conveyor belt 26 is sleeved between the two conveying rollers 25. One of the conveying shafts 24 is in driving connection with a driving assembly 27. The driving assembly 27 includes a second motor 28 fixedly connected to the conveying base plate 23. A driving dial 29 is fixedly connected to the rotor of the second motor 28. A driven sheave 30 is fixedly connected to the outer side of one of the conveying shafts 24, and the driving dial 29 cooperates with the driven sheave 30.

[0035] After the second motor 28 is turned on, it drives the active dial 29 to rotate, and the active dial 29 drives the driven groove wheel 30 to rotate, and then drives the conveyor belt 26 to periodically convey the pipe segments on the conveyor belt 26 forward. Due to the intermittent transmission, the pipe segments can be more conveniently clamped and installed at the corresponding points by subsequent equipment during the forward movement, and efficiency can be improved.

[0036] Example 3: This example discloses the following technical means based on the previous example: Please refer to Figure 5 A third motor 31 is rotatably connected to the moving beam 1, and a second screw 32 is fixedly connected to the rotor of the third motor 31. A push plate 33 is threadedly connected to the outer side of the second screw 32. The push plate 33 cooperates with the pipe segment on the conveying assembly 5. A monitoring assembly 34 is also fixedly connected to the moving beam 1. The monitoring assembly 34 is used to detect whether there are defects in the pipe segment on the conveying assembly 5. When defects are detected, the third motor 31 is turned on, and the push plate 33 pushes the pipe segment off the conveying assembly 5 during movement.

[0037] The rotation of the third motor 31 drives the push plate 33 to reciprocate in a direction perpendicular to the conveyor belt 26. When the monitoring component 34 detects damage to the pipe segment, the third motor 31 is activated to quickly push the damaged pipe segment away. After the fan blades 15 have blown away debris and dust on the pipe segment surface, it is easier for the monitoring component 34 to detect cracks on the pipe segment surface. The monitoring component 34 obtains and analyzes images of the pipe segment surface to determine whether the pipe segment surface is cracked.

[0038] Working Principle: During use, the device moves synchronously with the shield machine, and the rotation of the first motor 2 drives the rotation of the first screw 3. The rotation of the first screw 3 adjusts the position of the clamping assembly 4 to clamp the segment. After the clamping assembly 4 clamps the segment, it can be moved to the conveyor assembly 5 and quickly transported to the installation location for fast and convenient installation. The rotation of the first screw 3 drives the sliding frame 6 to move in the direction in which the segment needs to be transported. The movement direction is controlled by the steering of the first motor 2, facilitating continuous transport operations. The electric telescopic rod 7 moves up and down to clamp the segment. During this movement, the segment must first be lifted to a high enough position to prevent collision with the conveyor assembly 5. Once it moves above the conveyor assembly 5, it is lowered to place the segment in the transport position. The rotation of the clamping motor 10 drives the clamping shaft 11 to adjust the segment's orientation, facilitating subsequent installation in the optimal direction. The driven gears 16 are driven to rotate on both sides of the clamping shaft 11 through the transmission gears 17. During the rotation of the driven gears 16, the fan blades 15 are driven to rotate. The fan blades 15 can blow away dust and impurities on the pipe segments through the air outlet to prevent attached debris from affecting the installation quality. The clamping telescopic rod 22 is electrically driven. During the telescopic process, the clamping rod 19 is driven to swing toward or away from each other through the collar 21. When swinging toward each other, the clamping is performed, and when swinging away from each other, the pipe segment is released. After the second motor 28 is turned on, it drives the active dial 29 to rotate. The active dial 29 drives the driven sheave 30 to rotate, and then drives the conveyor belt 26 to periodically convey the pipe segments on the conveyor belt 26 forward. Due to the intermittent transmission, the pipe segments can be more conveniently clamped and installed at the corresponding points by subsequent equipment during the forward movement, and efficiency can be improved. The rotation of the third motor 31 drives the push plate 33 to reciprocate perpendicularly to the conveyor belt 26. When the monitoring component 34 detects damage to the pipe segment, the third motor 31 is activated to quickly push the damaged pipe segment away. After the fan blades 15 have blown away debris and dust from the pipe segment surface, it is also easier for the monitoring component 34 to detect cracks on the pipe segment surface. The monitoring component 34 obtains an image of the pipe segment surface and analyzes the image to determine whether the pipe segment surface is cracked. This technical means is conventional in the art.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0040] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
