Description

Technical Field

[0001] The utility model relates to the technical field of tunnel traffic auxiliary equipment, in particular to a vehicle passing mat rack for tunnels and a vehicle passing device for tunnels. Background Art

[0002] At present, for the existing tunnel lining concrete pouring construction, the trackless transportation sectional lining process is mostly adopted. This process constructs through multiple sections simultaneously, significantly improving the construction efficiency. However, there are also some deficiencies in this process. Specifically, a relative concrete thickness drop will form between the lined section and the unlined section, making it difficult for concrete tank trucks to pass during the construction process, thus affecting the construction progress. To solve this problem, in the existing technology, a slope-shaped cushion plate is often used to assist the tank truck to pass (for example, the Chinese patent document with the publication number CN209010884U discloses a step cushion plate for municipal engineering). Although the cushion plate can assist the tank truck to pass in areas with a large height difference, since the cross-sections of tunnel excavation and lining forming are mostly circular, and the bottom of the existing cushion plate is usually a horizontal plane, it is easy for the cushion plate to tilt when passing a vehicle in a circular cross-section tunnel, thus affecting the safety of passing a vehicle; when the tunnel is long, the geological conditions may change, and the concrete thickness of the tunnel lining will also change accordingly, resulting in a change in the relative concrete thickness drop between the lined section and the unlined section of the tunnel. However, the existing cushion plate can usually only assist the tank truck to pass under a specific height difference, with poor adaptability. Content of the Utility Model

[0031] First embodiment

[0032] Figures 1 to 8An embodiment of the vehicle passing cushion frame for tunnels of the present utility model is shown. The vehicle passing cushion frame for tunnels in this embodiment includes a first base 1, a longitudinal telescopic mechanism 5, a second base 2, a vertical telescopic mechanism 6, a connection seat 3, and multiple load-bearing rods 4 arranged side by side. The two ends of the longitudinal telescopic mechanism 5 are respectively connected to the first base 1 and the second base 2, and the two ends of the vertical telescopic mechanism 6 are respectively connected to the second base 2 and the connection seat 3. The bottom surfaces of the first base 1 and the second base 2 are both arc-shaped surfaces (see Figure 4 and Figure 5 ) for fitting with the curved bottom surface of the unlined section of the tunnel, and the top surface of the connection seat 3 is an arc-shaped surface (see Figure 6 ) for making the edge of the top surface of the connection seat 3 fit with the edge of the curved bottom surface of the lined section of the tunnel. The two ends of the load-bearing rod 4 are respectively arranged on the first base 1 and the connection seat 3. It should be noted that longitudinally is the length direction of the tunnel when in use in the tunnel, or in other words, the tunneling direction of the tunnel, and vertically is the height direction, or in other words, the direction of gravity.

[0033] For the vehicle passing cushion frame for tunnels in this embodiment, the bottom surfaces of the first base 1 and the second base 2 are arc-shaped surfaces to fit with the curved bottom surface of the unlined section of the tunnel, which can ensure that construction vehicles such as tank trucks in the tunnel will not tilt or shake when passing through, and is beneficial to ensuring the stability and safety during vehicle passing; the top surface of the connection seat 3 is an arc-shaped surface for making the edge of the top surface of the connection seat 3 fit with the edge of the curved bottom surface of the lined section of the tunnel, which is beneficial to ensuring the smoothness of the construction vehicle passing on the lined section of the tunnel and the connection seat 3, and improving the stability of vehicle passing; the longitudinal telescopic mechanism 5 can adjust the distance between the first base 1 and the second base 2 by telescoping, and the vertical telescopic mechanism 6 can adjust the distance between the second base 2 and the connection seat 3 by telescoping. By replacing load-bearing rods 4 of different lengths to connect the first base 1 and the connection seat 3, it can adapt to the passage of vehicles under different height differences, and has strong adaptability. Further, through the longitudinal telescopic mechanism 5 and the vertical telescopic mechanism 6, the ratio of the distance between the first base 1 and the second base 2 to the distance between the second base 2 and the connection seat 3 can be a fixed value, so that even if load-bearing rods 4 of different lengths are replaced, the inclination angle of the load-bearing rods 4 arranged at the corresponding positions can remain unchanged, ensuring that the vehicle always passes within a suitable slope range, and further improving the safety and stability.

[0034] Before use, measure the shapes of the cross-sections of the unlined section and the lined section of the tunnel, and select a suitable vehicle passing device for the tunnel. After the selection is completed, move the vehicle passing device for the tunnel so that the bottom surfaces of the first base 1 and the second base 2 are in contact with the bottom surface of the unlined section of the tunnel, and the edges of the upper surface of the second base 2 are in contact with the edges of the bottom surface of the unlined section of the tunnel. The vertical telescopic mechanism 6 adjusts the height of the connection seat 3 through telescoping until the upper surface of the connection seat 3 abuts and is flush with the edge of the curved bottom surface of the lined section of the tunnel. Subsequently, according to the set gradient, the longitudinal telescopic mechanism 5 telescopically adjusts the distance between the first base 1 and the second base 2. During the adjustment process, the first base 1 remains stationary. After the adjustment is completed, select a bearing rod 4 of an appropriate length to connect the first base 1 and the connection seat 3. After the bearing rod 4 is arranged, the vehicle can pass from the unlined section of the tunnel, successively pass through the first base 1, the bearing rod 4, and the connection seat 3 to reach the lined section of the tunnel. The vehicle can also pass from the lined section of the tunnel, successively pass through the connection seat 3, the bearing rod 4, and the first base 1 to reach the unlined section of the tunnel.

[0035] For details, see Figure 1 and Figure 2 Furthermore, in this embodiment, the longitudinal telescopic mechanism 5 includes a first threaded sleeve 51 fixedly arranged on the second base 2 and a first connecting rod 52 threadedly connected to the first threaded sleeve 51. One end of the first connecting rod 52 away from the first threaded sleeve 51 is rotatably connected to the first base 1. Rotating the first connecting rod 52, the first connecting rod 52 can extend or retract from the first threaded sleeve 51, thereby driving the first base 1 rotatably connected to the first connecting rod 52 to move away from or close to the second base 2. Specifically, the rotational connection between the first connecting rod 52 and the first base 1 can adopt the following solution: A bearing is fixedly arranged on the first base 1. One end of the first connecting rod 52 passes through the bearing. There are two fixing rings on the first connecting rod 52, and the two fixing rings are respectively located in front of and behind the bearing, and the diameters of the two fixing rings are larger than the inner diameter of the outer ring of the bearing. When the first connecting rod 52 rotates and telescopes, the two fixing rings will longitudinally move therewith to drive the bearing to move, thereby driving the first base 1 to move longitudinally.

[0036] For details, see Figure 1 and Figure 2 Furthermore, in this embodiment, the vehicle passing cushion frame for the tunnel further includes a support assembly 7 arranged on the first threaded sleeve 51, and the support assembly 7 supports on each bearing rod 4. It can improve the structural strength, reduce the deformation of the bearing rod 4 caused by compression, and improve the safety of vehicle passing. Further, the support assembly 7 is slidably adjustable on the first threaded sleeve 51 and supports on each bearing rod 4.

When the longitudinal telescopic mechanism 5 drives the first base 1 to move longitudinally, and the vertical telescopic mechanism 6 drives the docking seat 3 to rise and fall, different cushion blocks 72 can be replaced to ensure that the crossbeam 73 can always be supported on each bearing rod 4, thereby ensuring the supporting effect of the support assembly 7. Preferably, the fixing seat 71 is slidably sleeved on the first threaded sleeve 51 and locked on the first threaded sleeve 51 by screws.

When in use, the lower hoop body 712 is arranged on the lower side of the first threaded sleeve 51, and the cushion block 72 is connected to the upper hoop body 711 by bolts. After loosening the bolts at both ends of the upper hoop body 711 and the lower hoop body 712, the position of the fixing seat 71 on the first threaded sleeve 51 can be adjusted. After tightening, the fixing seat 71 is fixed on the first threaded sleeve 51, and the crossbeam 73 can be supported on the appropriate position of each bearing rod 4 by adjusting the position of the fixing seat 71, which is conducive to ensuring the bearing capacity of the bearing rod 4.
