Description

Technical Field

[0001] This utility model relates to the field of tunnel segment transportation, and specifically refers to a tunnel segment transportation anti-collision device. Background Technology

[0002] The current traditional transportation method is to use transport vehicles, but collisions and damage often occur during this process, resulting in the segments being damaged when they are delivered to the construction site. As a result, workers often need to make repairs or even return the segments, which increases costs.

[0003] Some existing anti-collision devices are fixed to transport vehicles by bolts or welding, which makes subsequent disassembly and maintenance more troublesome and affects efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a segment transportation anti-collision device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a segment transportation anti-collision device, comprising a transport vehicle, multiple contoured frames arranged sequentially along the length of the transport vehicle on the top surface for stacking segments, multiple buffer air cushions respectively arranged at both ends of the multiple contoured frames for buffering, multiple slides spaced apart on the top surface of the transport vehicle along the length of the transport vehicle and with one end penetrating one end face of the transport vehicle, multiple limiting grooves respectively arranged on the inner walls of the multiple slides on both sides of the multiple slides and with one end penetrating one end face of the transport vehicle, multiple support blocks correspondingly arranged on the bottom surface of the multiple contoured frames for sliding within the multiple slides, multiple limiting plates respectively arranged on one end of the multiple support blocks located within the multiple slides for sliding within the multiple limiting grooves, and limiting components arranged on the top surface of the transport vehicle near the openings of the multiple slides for limiting the multiple contoured frames; each of the multiple limiting plates is provided with a buffer rubber pad.

[0006] Preferably, the limiting component includes multiple sliding grooves respectively disposed at the bottom of the opening side of multiple sliding tracks; multiple blocks respectively slidably disposed in the multiple sliding grooves for limiting multiple support blocks; multiple clearance grooves correspondingly disposed on the transport vehicle and located on the side of the multiple blocks for the blocks to slide into; a toggle groove disposed on the transport vehicle on the length direction side and on the same horizontal line as the multiple clearance grooves; a drive rod with one end located in the toggle groove and the other end extending into the multiple sliding grooves to connect the multiple blocks; multiple springs respectively sleeved on the section of the drive rod located in the multiple clearance grooves to always push the multiple blocks toward the multiple sliding tracks; and a paddle disposed on the end of the drive rod located in the toggle groove.

[0007] Preferably, the plurality of contour frames are fixed to the plurality of support blocks by welding.

[0008] Preferably, each of the multiple contour frames is provided with a limiting strip on both sides.

[0009] Preferably, the multiple limiting strips are connected to multiple contoured frames by bolts.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] This invention places the tube segments directly onto the contour frame, and then uses the buffer air cushions between the contour frames and the buffer rubber pads on the limiting plate to buffer them, effectively avoiding collisions caused by road bumps and other problems during transportation, thus improving the quality of the tube segments. The limiting component can also effectively and quickly limit multiple contour frames in multiple slides at the same time, making it convenient for disassembly and assembly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Appendix Figure 1-3The anti-collision device for transporting tunnel segments according to this utility model includes a transport vehicle 1, multiple contoured frames 2 arranged sequentially along the length of the transport vehicle 1 on the top surface of the transport vehicle 1 for stacking tunnel segments, multiple cushioning air cushions 3 respectively arranged at both ends of the multiple contoured frames 2 for buffering, multiple slides 4 spaced apart on the top surface of the transport vehicle 1 along the length of the transport vehicle 1 and with one end penetrating one end face of the transport vehicle 1, multiple limiting grooves 5 respectively arranged on the inner walls of the multiple slides 4 on both sides of the multiple slides 4 and with one end penetrating one end face of the transport vehicle 1, multiple support blocks 6 correspondingly arranged on the bottom surface of the multiple contoured frames 2 for sliding within the multiple slides 4, multiple limiting plates 7 respectively arranged on one end of the multiple support blocks 6 located within the multiple slides 4 for sliding within the multiple limiting grooves 5, and limiting components arranged on the top surface of the transport vehicle 1 near the opening of the multiple slides 4 for limiting the multiple contoured frames 2. 8; Each of the multiple limiting plates 7 is provided with a buffer rubber pad 9; The limiting component 8 includes multiple sliding grooves 81 respectively provided at the bottom of the opening side of multiple slides 4, multiple blocks 82 respectively slidably provided in the multiple sliding grooves 81 for limiting multiple support blocks 6, multiple clearance grooves 83 correspondingly provided on the transport vehicle 1 and located on the side of the multiple blocks 82 for the blocks 82 to slide into, a toggle groove 84 provided on the transport vehicle 1 on the length direction and on the same horizontal line as the multiple clearance grooves 83, a drive rod 85 with one end located in the toggle groove 84 and the other end extending into the multiple sliding grooves 81 to connect the multiple blocks 82, multiple springs 86 respectively sleeved on the section of the drive rod 85 located in the multiple clearance grooves 83 to always push the multiple blocks 82 toward the multiple slides 4, and a paddle 87 provided on the end of the drive rod 85 located in the toggle groove 84.

[0019] Furthermore, the multiple contoured frames 2 are fixed to the multiple support blocks 6 by welding to improve the stability.

[0020] Furthermore, each of the multiple contour frames 2 is provided with a limiting strip plate 10 on both sides to prevent the segments from shifting.

[0021] Furthermore, the multiple limiting strips 10 are connected to multiple contoured frames 2 by bolts, which facilitates disassembly.

[0022] In use: When transporting segments, first move the lever 87 to move the drive rod 85. Then, the drive rod 85 moves the stop block 82 into the clearance groove 83. After the stop block is fully slid into the clearance groove 83, align the support blocks 6 and limiting plates 7 at the bottom of the multiple contour frames 2 with the openings of the slide rail 4 and the limiting groove 5, respectively. Then, slide the support blocks 6 and limiting plates 7 into the slide rail 4 and the limiting groove 5, respectively. After the last contour frame 2's bottom support block 6 and limiting plate 7 have slid in, release the lever 87, and the spring 86 will immediately lose its function. The resistance pushes the stop block 82 back into the slide 4. At this time, the limiting plate 7 on the bottom support block 6 of the last contour frame 2 is in contact with the stop plate. Then the stop block 82 limits the limiting plate 7, so that multiple contour frames 2 are limited on the transport vehicle 1. Then the buffer airbags at both ends of multiple contour frames 2 are inflated until the buffer airbags on two contour frames 2 that are close to each other are in contact with each other. Then the segments are hoisted onto each contour frame 2. After hoisting, they are transported to the construction site by the transport vehicle 1.

[0023] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
