Description

Technical Field

[0001] The present invention relates to the technical field of highway tunnel construction, and particularly to a construction device for in-situ maintenance or expansion of highway tunnels. Background Art

[0002] A highway tunnel is a passage built underground for vehicles to travel, and generally also serves as a passage for pipelines and pedestrians, etc.

[0003] When repairing or expanding an existing tunnel, the method of temporarily closing one-way traffic is usually adopted, that is, construction is carried out with one side closed to traffic, and after the construction is completed, the other lane is closed to traffic for construction, so as to provide sufficient space and time for construction operations. And this means of closing one-way traffic will inevitably bring great pressure to road traffic. Especially for urban highway tunnels, it will cause large-scale congestion in urban traffic, bringing very adverse effects to public interests and social benefits.

[0004] Therefore, if in-situ maintenance or expansion of the tunnel can be carried out without interrupting traffic, the traffic pressure brought by the closure and restriction of traffic will be greatly reduced. In the prior art, in order to reduce the adverse effects brought by engineering construction to public interests and social benefits, a frame with a support structure is usually used to move in the tunnel, and a construction device is arranged on the frame to construct the top of the tunnel, so that vehicles can pass through the bottom, avoiding traffic interruption construction and not causing congestion. However, most of the devices in the prior art move in the tunnel through moving wheels. Although the wheels can be locked during construction, there are still disadvantages of insufficient stability. At the same time, when constructing in the tunnel, since the vehicles are in a passing state, there is a disadvantage that the frame may be collided by traffic accidents, which in turn affects the stability of the frame and the safety of the overall construction.

[0038] In an embodiment of the present invention, referring to Figure 2 , specifically, the through hole 4 is square, and the cross section of the support rod 5 is also square. By moving the support rod 5 downward, the support plate 6 is driven to contact the ground, realizing the stable contact between the frame body 1 and the ground and ensuring the stability during construction.

[0039] As an alternative embodiment, the folding member includes a rotating shaft 7 rotatably connected within the cavity. Both ends of the rotating shaft 7 are fixedly connected with a first bevel gear 8. Both ends within the cavity are rotatably connected with a threaded rod 9.

Fixing blocks 22 are fixedly connected to both ends of the protection plate 3. The other ends of the two buffer rods 21 located within the same buffer groove 18 are both hinged to the fixing block 22.

[0044] In one embodiment of the present invention, referring to Figure 1 、 Figure 3 , a plurality of fixing plates 17 are fixedly connected to the frame 1 along the circumferential direction, and the protection plates 3 are installed one by one correspondingly. When an external force acts on the protection plate 3, it moves towards the fixing plate 17. When moving, the buffer rod 21 drives the buffer block 20 to slide on the sliding rod 19 for buffering.

[0045] As an alternative embodiment, buffer springs 23 are sleeved at both ends of the sliding rod 19, and two ends of the buffer springs 23 are fixedly connected to the inner wall of the buffer groove 18 and the side wall of the buffer block 20 respectively.

[0046] In an embodiment of the present invention, referring to Figure 3 , when the protection plate 3 moves towards the fixed plate 17 under an external force, the buffer springs 23 are deformed to apply an elastic force, thereby playing a buffering role to offset the external force.

[0047] As an alternative embodiment, a buffer bottom plate 24 is fixedly connected to one side of the fixed plate 17 close to the protection plate 3, a buffer top block 25 is fixedly connected to one side of the protection plate 3 close to the fixed plate 17, and the buffer top block 25 is adapted to the buffer bottom plate 24.

[0048] In an embodiment of the present invention, referring to Figure 4 , when the displacement of the protection plate 3 is relatively large, the buffer top block 25 is inserted into the buffer bottom plate 24 for auxiliary buffering, so as to improve the buffering ability.

Hemispherical protrusions 28 are fixedly connected to both sides of the open end of the buffer bottom plate 24, and the hemispherical protrusions 28 are in contact with the buffer top block 25.

[0052] In an embodiment of the present invention, referring to Figure 4 , the buffer bottom plate 24 is of a C-shaped structure, and the open end faces the protection plate 3. When the protection plate 3 moves towards the buffer bottom plate 24 under an external force, on the one hand, buffering is carried out through the buffer springs 23, and on the other hand, when its displacement distance is relatively large, the buffer top block 25 of the semi-circular structure is inserted into the buffer bottom plate 24 to drive the buffer bottom plate 24 to undergo elastic deformation, further improving the buffering ability. At the same time, the hemispherical protrusions 28 provided ensure stable contact with the buffer top block 25 and reduce the friction therebetween, ensuring that the buffer top block 25 drives the buffer bottom plate 24 to undergo stable deformation.

[0053] As an alternative embodiment, the frame 1 includes a left frame 101 and a right frame 102. The left frame 101 and the right frame 102 are slidably connected, and fixing grooves 103 are fixedly connected to both sides of the top ends of the left frame 101 and the right frame 102.

After adjustment, the top sealing plate 30 is laid in the fixing groove 103 to close the top opening.
