A tunnel segment transport bracket

Abstract

This application relates to a tunnel segment transport bracket, specifically in the technical field of tunnel segment transport, and includes a base plate. The application employs a cooperative structure consisting of a rotating rod, a threaded rod, a threaded cylinder, and a movable plate. When a knob is turned, the transmission rod and worm gear rotate. Through the meshing of the worm gear and worm wheel, the rotating rod rotates synchronously, causing the threaded rods at both ends to rotate. Simultaneously, the threaded cylinder moves axially along the surface of the threaded rod, causing the movable plate and the top U-shaped clamping plate to move closer or further apart, thus achieving initial clamping of segments of different sizes. Furthermore, by rotating the auxiliary bolt, the top block is pushed to press against the auxiliary plate, causing the auxiliary plate to move towards the segment surface under the guidance of the sliding rod. The inner contact surface of the auxiliary plate allows for close contact with the segment, further enhancing the fixing effect and effectively avoiding the loosening problem caused by the difficulty of traditional rope binding to conform to curved surfaces.

Description

Technical Field

[0001] This application relates to tunnel segment transportation, and more particularly to a tunnel segment transportation bracket. Background Technology

[0002] In tunnel construction, segments are typically used to construct the tunnel structure. The transportation of segments is an important part of tunnel construction, and a transport bracket is required.

[0003] Traditional support brackets mostly use ropes to bind and fix tunnel segments. However, due to the curved shape of the tunnel segments, it is difficult for the ropes to fit tightly, and they are prone to loosening during long-term transportation, resulting in poor fixing effect. At the same time, existing support brackets generally lack shock absorption and cushioning measures, and vehicle vibration is directly transmitted to the tunnel segments, which may cause micro-cracks inside the tunnel segments, reducing their structural strength and service life. In order to solve the above problems, a tunnel segment transportation support bracket is proposed. Utility Model Content

[0004] The purpose of this application is to provide a tunnel segment transport bracket with advantages such as a tightly fitting fixing structure and shock absorption function. It solves the problem of loosening caused by the inability of ropes to fit tightly against the curved surface when fixing segments in traditional brackets, as well as the problem that the lack of shock absorption measures makes it easy for vehicle vibration to cause micro-cracks inside the segments, reducing structural strength and service life.

[0005] This application provides a tunnel segment transport bracket with the following technical solution: It includes a base plate, the top of which has a movable groove with two through holes. Two fixed plates are fixedly connected inside the movable groove. A rotating rod is tightly nested between the two fixed plates via bearings. Threaded rods are fixedly connected to both ends of the rotating rod. The shaft end of the threaded rod is rotatably connected to the inner side of the movable groove. A threaded cylinder is threadedly connected to the surface of the threaded rod, and a movable plate is fixedly connected to the surface of the threaded cylinder. A transmission rod is tightly nested within the inner side of the movable groove via bearings. A worm gear is fixedly connected to the surface of the rotating rod, and a worm wheel is fixedly connected to the surface of the rotating rod. The worm gear and the worm wheel mesh with each other. One end of the transmission rod rotates through the side of the movable slot and is fixedly connected to a knob. A U-shaped clamping plate is fixedly connected to the top of the movable plate. Two sliding rods are slidably connected to the side of the U-shaped clamping plate. An auxiliary plate is fixedly connected to one end of the sliding rod, and a limit plate is fixedly connected to the other end of the sliding rod. A threaded cap is fixedly connected to the side of the U-shaped clamping plate. An auxiliary bolt is threadedly connected inside the threaded cap. A top block is fixedly connected to one end of the auxiliary bolt, and the side of the top block overlaps the side of the auxiliary plate. By adopting the above technical solution, and by setting up a cooperative structure of rotating rod, threaded rod, threaded cylinder, and movable plate, when the knob is turned, the transmission rod and worm gear can be rotated. Through the meshing of the worm gear and worm wheel, the rotating rod can be driven to rotate synchronously, causing the threaded rods at both ends to rotate. At this time, the threaded cylinder moves axially on the surface of the threaded rod, which can drive the movable plate and the top U-shaped clamping plate to move closer or further apart, thereby achieving initial clamping of segments of different sizes. At the same time, by rotating the auxiliary bolt, the top block can be pushed to squeeze the auxiliary plate, causing the auxiliary plate to move towards the surface of the segment under the guidance of the sliding rod. The inner contact surface of the auxiliary plate can be used to make close contact with the segment, which can further enhance the fixing effect and effectively avoid the loosening problem caused by the difficulty of traditional rope binding to fit the arc surface.

[0006] Preferably, a strip pad is provided on one side of the bottom end inside the U-shaped clamping plate; By adopting the above technical solution and setting a strip pad, its elastic material properties can be used to fully contact the bottom surface of the tube segment, effectively filling the gap between the tube segment and the U-shaped clamping plate, and avoiding wear on the tube segment surface caused by rigid contact.

[0007] Preferably, a fixed frame is fixedly connected to each of the four corners of the bottom of the base plate, and a shock absorber is fixedly connected to each of the four corners of the bottom of the base plate. The shock absorber is located inside the fixed frame, and a wheel is fixedly connected to the bottom end of the shock absorber. By adopting the above technical solution and setting up a combination structure of fixed frame, shock absorber and wheels, when the transport bracket moves on uneven road surface, the shock absorber can effectively absorb the impact force generated by road bumps, and prevent the bracket and tube segments from being displaced or damaged due to vibration. At the same time, the fixed frame can guide and limit the extension and retraction of the shock absorber, and can prevent the shock absorber from deflecting during the stress process.

[0008] Preferably, the bottom plate has through slots at all four corners of the top, and a fixing rod is fixedly connected to the inner side of the through slot. Two stabilizing blocks are fixedly connected to the bottom of the U-shaped clamping plate, and the stabilizing blocks are slidably connected to the surface of the fixing rod. By adopting the above technical solution, and by setting a cooperative structure of through groove, fixing rod and stabilizing block, when it is necessary to adjust the position of U-shaped clamping plate according to different sizes of pipe segments, the stabilizing block can slide along the surface of the fixing rod, which can realize the flexible movement of U-shaped clamping plate on the base plate, thereby quickly adapting to the width requirements of pipe segments.

[0009] Preferably, folding and shrinking plates are fixedly connected to both sides of the movable plate, and one end of the folding and shrinking plate is fixedly connected to the inner side of the through hole. By adopting the above technical solution and setting up a connection structure between the folding shrink plate, the movable plate, and the through hole, when the movable plate moves back and forth in the through hole to adapt to segments of different lengths, the folding shrink plate will expand or retract synchronously with the movement of the movable plate. This can reduce the impact of external dust, debris, etc., entering the through hole and affecting the normal transmission of the threaded rod and the threaded cylinder.

[0010] Preferably, each of the four corners of the top of the base plate is fixedly connected with a manual adjustment rod, the four manual adjustment rods are located between two U-shaped clamping plates, and the top of each manual adjustment rod is fixedly connected with a support bracket; By adopting the above technical solution and setting a combination structure of manual adjustment rod and support bracket, after the segment is placed between the U-shaped clamping plates, the height of the support bracket can be adjusted by rotating the manual adjustment rod, so that the support bracket can provide auxiliary support from the bottom of the segment, which can further improve the stability of the segment during transportation.

[0011] Preferably, a stabilizing screw cylinder is fixedly connected to each of the opposite sides of the base plate, a stabilizing bolt is threaded inside the stabilizing screw cylinder, and a stabilizing plate is fixedly connected to the bottom end of the stabilizing bolt. By adopting the above technical solution and setting up a cooperative structure of stabilizing screw, stabilizing bolt and stabilizing plate, when the bracket is placed on the transport vehicle or the ground, the stabilizing plate can be moved downward by turning the stabilizing bolt until it is in close contact with the contact surface. The contact area between the bracket and the contact surface can be increased by the stabilizing plate. At the same time, the thread locking effect of the stabilizing bolt can prevent the bracket from sliding or tipping over during transportation or when stationary.

[0012] Preferably, a push handle is fixedly connected to one side of the top of the base plate; By adopting the above technical solution and by setting a push handle, the operator can easily move the entire bracket by holding the push handle.

[0013] In summary, this application includes at least one of the following beneficial technical effects: This tunnel segment transport bracket features a structure consisting of a rotating rod, a threaded rod, a threaded cylinder, and a movable plate. Turning the knob rotates the transmission rod and worm gear. Through the meshing of the worm gear and worm wheel, the rotating rod rotates synchronously, causing the threaded rods at both ends to rotate. The threaded cylinder moves axially along the surface of the threaded rod, causing the movable plate and the top U-shaped clamping plate to move closer or further apart, thus achieving initial clamping of segments of different sizes. Simultaneously, rotating the auxiliary bolt pushes the top block to press against the auxiliary plate, causing the auxiliary plate to move towards the segment surface under the guidance of the sliding rod. The inner contact surface of the auxiliary plate makes close contact with the segment, further enhancing the fixing effect and effectively avoiding the loosening problem caused by the difficulty of traditional rope binding to conform to curved surfaces.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0017] Example 1: A tunnel segment transport bracket, referring to Figure 1 , Figure 3 and Figure 4The system includes a base plate 1, with a movable groove 101 at its top. Two through holes 102 are located at the top of the movable groove 101. Two fixed plates 103 are fixedly connected inside the movable groove 101. A rotating rod 104 is tightly nested between the two fixed plates 103 via bearings. Threaded rods 106 are fixedly connected to both ends of the rotating rod 104. The shaft ends of the threaded rods 106 are rotatably connected to the inner side of the movable groove 101. A threaded cylinder 107 is threadedly connected to the surface of the threaded rods 106. A movable plate 108 is fixedly connected to the surface of the threaded cylinder 107. A transmission rod 1 is tightly nested inside the inner side of the movable groove 101 via bearings. 011, a worm gear 1013 is fixedly connected to the surface of the transmission rod 1011, and a worm wheel 105 is fixedly connected to the surface of the rotating rod 104. The worm gear 1013 and the worm wheel 105 mesh with each other. One end of the transmission rod 1011 rotates through the side of the movable slot 101 and is fixedly connected to a knob 1012. A U-shaped clamping plate 109 is fixedly connected to the top of the movable plate 108. Two slide rods 1014 are slidably connected to the side of the U-shaped clamping plate 109. An auxiliary plate 1015 is fixedly connected to one end of the slide rod 1014, and a limit plate 1016 is fixedly connected to the other end of the slide rod 1014. The side of the U-shaped clamping plate 109 is fixedly connected to... A threaded cap 1017 is attached, and an auxiliary bolt 1018 is threadedly connected inside the threaded cap 1017. One end of the auxiliary bolt 1018 is fixedly connected to a top block 1019, and the side of the top block 1019 overlaps the side of the auxiliary plate 1015. Through the cooperative structure of the rotating rod 104, threaded rod 106, threaded cylinder 107, and movable plate 108, when the knob 1012 is rotated, the transmission rod 1011 and worm gear 1013 can be driven to rotate. Through the meshing action of the worm gear 1013 and worm wheel 105, the rotating rod 104 can be driven to rotate synchronously, causing the threaded rods 106 at both ends to rotate. When the threaded cylinder 107 moves axially on the surface of the threaded rod 106, it can drive the movable plate 108 and the top U-shaped clamping plate 109 to move closer or further apart, thereby achieving initial clamping of segments of different sizes. At the same time, by rotating the auxiliary bolt 1018, the top block 1019 can be pushed to squeeze the auxiliary plate 1015, so that the auxiliary plate 1015 moves towards the surface of the segment under the guidance of the slide rod 1014. The inner contact surface of the auxiliary plate 1015 can be used to make close contact with the segment, which can further enhance the fixing effect and effectively avoid the loosening problem caused by the difficulty of traditional rope binding to fit the arc surface.

[0018] Please see Figure 1 , Figure 3 and Figure 5A strip pad 1010 is provided on one side of the bottom of the U-shaped clamping plate 109. By providing the strip pad 1010, its elastic material properties can fully contact the bottom surface of the pipe segment, effectively filling the gap between the pipe segment and the U-shaped clamping plate 109, and avoiding wear on the pipe segment surface caused by rigid contact. Fixed frames 1026 are fixedly connected to the four corners of the bottom of the base plate 1, and shock absorbers 1027 are fixedly connected to the four corners of the bottom of the base plate 1. The shock absorbers 1027 are located inside the fixed frames 1026, and wheels 1028 are fixedly connected to the bottom of the shock absorbers 1027. Through the combination structure of the fixed frames 1026, shock absorbers 1027 and wheels 1028, when the transport bracket moves on uneven roads, the shock absorbers 1027 can effectively absorb the impact force generated by road bumps, preventing the bracket and pipe segment from shifting due to vibration. In addition, the fixed frame 1026 can guide and limit the telescopic movement of the shock absorber 1027, preventing the shock absorber 1027 from tilting during the stress process. The four corners of the top of the base plate 1 are provided with through grooves 1020. The inside side of the through grooves 1020 is fixedly connected to the fixed rods 1021. The bottom of the U-shaped clamping plate 109 is fixedly connected to two stabilizing blocks 1022. The stabilizing blocks 1022 are slidably connected to the surface of the fixed rods 1021. By setting the cooperative structure of the through grooves 1020, fixed rods 1021 and stabilizing blocks 1022, when it is necessary to adjust the position of the U-shaped clamping plate 109 according to the different sizes of the pipe segments, the stabilizing blocks 1022 can slide along the surface of the fixed rods 1021, which can realize the flexible movement of the U-shaped clamping plate 109 on the base plate 1, thereby quickly adapting to the width requirements of the pipe segments.

[0019] Please see Figure 1 , Figure 3 and Figure 5Folding and retractable plates 1032 are fixedly connected to both sides of the movable plate 108. One end of the folding and retractable plate 1032 is fixedly connected to the inner side of the through hole 102. By setting the connection structure between the folding and retractable plate 1032, the movable plate 108, and the through hole 102, when the movable plate 108 moves back and forth in the through hole 102 to adapt to segments of different lengths, the folding and retractable plate 1032 will expand or retract synchronously with the movement of the movable plate 108, which can reduce the entry of external dust, debris, etc. into the through hole 102. 2. Internally, the normal transmission between the threaded rod 106 and the threaded cylinder 107 is affected. Manual adjustment rods 1030 are fixedly connected to the four corners of the top of the base plate 1. These four manual adjustment rods 1030 are positioned between two U-shaped clamping plates 109. Support brackets 1031 are fixedly connected to the top of each manual adjustment rod 1030. By setting up this combination structure of manual adjustment rods 1030 and support brackets 1031, after the tube segment is placed between the U-shaped clamping plates 109, the support brackets 1031 can be adjusted by rotating the manual adjustment rods 1030. The height of the base plate 1 allows the support bracket 1031 to provide auxiliary support from the bottom of the segment, further improving the stability of the segment during transportation. Stabilizing screw cylinders 1023 are fixedly connected to both sides of the base plate 1. Stabilizing bolts 1024 are threaded inside the stabilizing screw cylinders 1023, and stabilizing plates 1025 are fixedly connected to the bottom of the stabilizing bolts 1024. Through the coordinated structure of the stabilizing screw cylinders 1023, stabilizing bolts 1024, and stabilizing plates 1025, when the bracket is placed on a transport vehicle or the ground, the stabilizing plates 1025 can be moved downwards by tightening the stabilizing bolts 1024 until they are tightly fitted with the contact surface. The stabilizing plates 1025 increase the contact area between the bracket and the contact surface. Simultaneously, the threaded locking effect of the stabilizing bolts 1024 prevents the bracket from sliding or tipping over during transportation or when stationary. A push handle 1029 is fixedly connected to one side of the top of the base plate 1. By holding the push handle 1029, the operator can easily push the entire bracket to move.

[0020] The implementation principle of this application embodiment is as follows: When transporting the tray, the tray is first moved to the segment storage position by push handle 1029. Then, according to the size of the segment, knob 1012 is rotated. Knob 1012 drives transmission rod 1011 and worm gear 1013 to rotate. Through the meshing of worm gear 1013 and worm wheel 105, rotating rod 104 is driven to rotate, so that threaded rods 106 at both ends rotate synchronously. Threaded cylinder 107 drives movable plate 108 and U-shaped clamping plate 109 to slide along fixed rod 1021 in movable groove 101, realizing that U-shaped clamping plates 109 move closer or further apart, adjusting to a position suitable for the width of the segment. Then, movable plate... During the movement of 108, the folding and retracting plates 1032 on both sides will unfold or retract with the movement of the movable plate 108, blocking the through hole 102. Then, the tube is placed between the two U-shaped clamping plates 109, with the bottom of the tube contacting the strip pad 1010. Then, the auxiliary bolt 1018 is rotated to push the top block 1019 to press the auxiliary plate 1015, so that the auxiliary plate 1015 fits tightly against the side of the tube under the guidance of the slide rod 1014, completing the initial fixation. After that, the manual adjustment rod 1030 is rotated to adjust the height of the support bracket 1031, so that it provides auxiliary support from the bottom of the tube. After the support is completed, the tube can be transported. When it is necessary to fix the bracket to the transport vehicle or the ground, tighten the stabilizing bolt 1024 to move the stabilizing plate 1025 downward until it is in contact with the contact surface to prevent the bracket from sliding. During transportation, if an uneven road surface is encountered, the shock absorber 1027 at the bottom of the base plate 1 will absorb the impact force generated by the bumps. The fixing frame 1026 plays a guiding and limiting role on the extension and retraction movement of the shock absorber 1027 to prevent the segments from being displaced or damaged due to vibration.
