Description

Technical Field

[0001] This utility model belongs to the field of tunnel segment transportation technology, specifically relating to a support for a shield tunnel segment transportation vehicle. Background Technology

[0002] With the rapid development of high-speed railways, the demand for tunnel engineering is increasing daily. Shield tunneling technology, with its advantages of high efficiency, safety, and environmental friendliness, has become an important means of tunnel construction. The shield tunneling method uses a movable shield shell at the excavation face to cut and remove soil, and simultaneously assembles precast tunnel segments (box culverts) to form the tunnel lining, thereby effectively controlling ground settlement and reducing the impact on the surrounding environment. However, shield tunnel construction faces complex geological conditions and technical challenges, among which quality control in the segment transportation stage is particularly critical.

[0003] As high-grade precast concrete components, the quality of tunnel segments directly affects the structural safety and durability of the tunnel. During transportation, segments may be damaged, cracked, or have dimensional deviations due to vibration, collision, or improper stacking, thus affecting assembly accuracy and the overall quality of the tunnel. Therefore, optimizing transportation processes, reducing transportation losses, and ensuring that segments arrive at the construction site intact have become important issues in the quality control of shield tunnel construction. In current technologies, segment transportation largely relies on specialized vehicles and fixed equipment, but further improvements are needed in transportation stability, collision protection, and loading / unloading efficiency to meet the high-quality requirements of complex construction environments. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one aspect of the purpose of this utility model is to provide a support for a shield tunnel segment transport vehicle. The support includes an arc-shaped channel steel plate frame, a transverse fixing plate, and a longitudinal fixing plate. The arc-shaped channel steel plate frame is elongated, with its long side matching the width of the transport vehicle body. One side of the long side is higher than the other. The arc-shaped channel steel plate frames are symmetrically arranged in pairs on the transport vehicle body, with the lower long side facing each other. The transverse fixing plates are symmetrically arranged in pairs on both sides of the transport vehicle body, with each pair of transverse fixing plates positioned between the two points of each pair of arc-shaped channel steel plate frames. The longitudinal fixing plate is positioned on the transverse fixing plate.

[0005] Preferably, the arc-shaped channel steel plate frame includes an arc-shaped channel steel plate skeleton, movable steel plate panels, and hydraulic telescopic support rods. A plurality of movable steel plate panels are disposed on the upper surface of the arc-shaped channel steel plate skeleton, and the number of the plurality of hydraulic telescopic support rods corresponds to the number of movable steel plate panels. Each hydraulic telescopic support rod is disposed below each movable steel plate panel and is fixedly connected to the movable steel plate panel. The hydraulic telescopic support rods are perpendicularly connected to the movable steel plate panels.

[0006] Preferably, the arc-shaped channel steel plate frame further includes anti-slip rubber pads for the movable steel plate panels and anti-slip rubber pads for the arc-shaped channel steel plate skeleton. A plurality of the anti-slip rubber pads for the movable steel plate panels are fixedly arranged on a plurality of movable steel plate panels, and the anti-slip rubber pads for the arc-shaped channel steel plate skeleton are arranged on the side of the arc-shaped channel steel plate frame with the longer side lower, and the length is consistent with the length of the arc-shaped channel steel plate frame.

[0007] Preferably, the arc-shaped channel steel plate frame further includes lifting lugs, which are located at the center of both sides of the short side of the arc-shaped channel steel plate frame.

[0008] Preferably, the transverse fixing plate includes a clamping plate, an adjusting slide groove, a motor, a sliding nut, and a double-acting screw. The adjusting slide groove is disposed on the upper surface of the transport vehicle body. The adjusting slide groove is rotatably connected to the double-acting screw via a bearing. One end of the double-acting screw is fixedly connected to the motor. Sliding nuts are respectively sleeved on both ends of the double-acting screw. The sliding nuts are slidably connected to the double-acting screw and disposed within the adjusting slide groove. The clamping plate is fixedly connected to the sliding nuts.

[0009] Preferably, the transverse fixing plate further includes a through groove, which is located at the center of the transverse fixing plate.

[0010] Preferably, the longitudinal fixing plate further includes a push plate, a hydraulic push rod, a fixing plate, a spring, and a slide groove. The hydraulic push rod is fixedly connected to the push plate and is disposed on the bottom edge of the horizontal side of the through groove. The hydraulic push rod is fixedly connected to the through groove. The slide groove is disposed at the center of the vertical sides of the through groove. The two sides of the fixing plate are slidably connected to the slide groove. The fixing plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the top edge of the horizontal side of the through groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] The symmetrical arrangement of two pairs of arc-shaped channel steel plates, matching the outer contour of the tunnel segments, effectively limits the displacement and swaying of the segments during transportation, reducing the risk of damage caused by vibration or bumps. The transverse and longitudinal fixing plates form a rigid support frame, dispersing impact forces during transportation and preventing cracks or chipping at the edges of the segments due to impacts. The arc-shaped channel steel plates feature a height difference design, facilitating segment alignment and rapid loading and unloading, reducing manual adjustment time and improving construction efficiency. This support structure can be adjusted according to different segment sizes, making it suitable for various shield tunnel construction scenarios and meeting high-quality transportation requirements. The structure is simple, reliable, and durable, allowing for long-term use and reducing additional maintenance or replacement costs due to damage to transportation equipment.

[0025] The arc-shaped channel steel plate frame 1 is a long strip with the long side being the same width as the transport vehicle body. One side of the long side is higher than the other side.
