Description

Technical Field

[0001] The utility model relates to the technical field of tunnel secondary lining, and particularly relates to a double - assembled trolley for the secondary lining of an emergency parking belt in a highway tunnel. Background Technique

[0002] During the tunnel construction process, the tunnel secondary lining trolley is mainly used for pouring concrete in multiple areas inside the tunnel to reinforce the inside of the tunnel. Generally, for highway tunnels longer than 500 meters, emergency parking belts are provided in the middle. The width of the parking belt is greater than the width of the tunnel. When lining the tunnel, concrete is poured into the pouring area enclosed by the formwork on the trolley and the tunnel wall. After the concrete solidifies, a semi - circular tunnel inner wall is formed. When lining the parking belt, the formwork extended by the ordinary trolley is too small to enclose a pouring area with the tunnel wall, resulting in difficult pouring. Therefore, a double - assembled trolley for the secondary lining of an emergency parking belt in a highway tunnel is provided. Content of the Utility Model

[0003] The purpose of the utility model is: to solve the problems in the above - mentioned background technique, the utility model provides a double - assembled trolley for the secondary lining of an emergency parking belt in a highway tunnel.

Detailed Embodiments

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] As Figures 1-4As shown in the figure, a double-jointed formwork trolley for the secondary lining of an emergency parking bay in a highway tunnel includes a tunnel 1. Inside the tunnel 1, there is a standard cross-section 2 and an emergency parking bay cross-section 3. Inside the emergency parking bay cross-section 3 of the tunnel 1, formwork trolley bodies 4 are symmetrically installed on the left and right. On the outer surface and the top of the formwork trolley body 4, a formwork assembly 5 is fixedly installed. Between the two formwork trolley bodies 4 on both sides, a connection assembly 6 is fixedly installed. By moving some structures of the formwork trolley bodies 4 on both sides and the formwork assembly 5 and the connection assembly 6 connected thereto from inside the standard cross-section 2 of the tunnel 1 to inside the emergency parking bay cross-section 3, and then connecting the structures inside the connection assembly 6 on both sides of the device inside the tunnel 1 to complete the overall assembly of the device, and then propping up the structure of the formwork assembly 5, pouring can be carried out. During actual use, the part of the device installed on one side of the emergency parking bay should be transported into the tunnel 1 first. After adjusting the position, the other side is transported. After being transported in, assembly can be carried out.

[0020] As Figure 2 , 3 shown, in some embodiments, the formwork assembly 5 includes a formwork one 501 and a formwork two 502. On both sides of the inner surface of the tunnel 1 in the emergency parking bay cross-section 3, the formwork one 501 and the formwork two 502 are symmetrically arranged. Above the formwork two 502 on both sides of the inner surface of the tunnel 1, a formwork three 503 and a formwork four 504 are distributed. At both ends of the articulated parts 505 are fixedly connected between the adjacent formwork one 501 and formwork two 502, between the formwork two 502 and formwork three 503, and between the formwork two 502 and formwork four 504. On the adjacent surfaces of the formwork one 501 and the formwork trolley body 4, a connection block one 506 is fixedly connected. The two connection blocks one 506 are rotatably connected to both ends of a hydraulic rod 507. Between the formwork three 503, the formwork four 504 and the upper surface of the adjacent formwork trolley body 4, another four connection blocks one 506 and hydraulic rods 507 are respectively installed. Near the top of the inner surface of the formwork two 502, a fixed block 508 is fixedly connected. Between the lower surface of the fixed block 508 and the upper surface of the adjacent formwork trolley body 4, a hydraulic rod 507 is vertically arranged and fixedly connected. Specifically, by starting the hydraulic rod 507 to contract to the minimum state and moving it through the part of the standard cross-section 2 of the tunnel 1 to the emergency parking bay cross-section 3, then the inner rod of the hydraulic rod 507 is extended to push the formwork outwards to contact the surface of the tunnel 1, and then pouring is carried out. After pouring is completed, the inner rod is contracted to reduce the volume of the device, and it is transported out of the tunnel 1. The hydraulic rod 507 connected to the formwork four 504 is contracted to adjust the formwork four 504 into the standard cross-section 2 so as to normally pass through the tunnel 1.

[0021] As Figure 2As shown, in some embodiments, the template four 504 extends above the other trolley body 4. The contact surfaces of the template three 503 and the template four 504 are set to be inclined. Specifically, after the template three 503 presses against the inner wall of the tunnel 1 through the set inclined surface, the template four 504 is then pressed against the inner wall of the tunnel 1. At the same time, the inclined surface of the template four 504 will press against the inclined surface of the template three 503, thereby completing the connection of the two templates on both sides of the template assembly 5.

[0022] As Figure 4 shown, in some embodiments, the connection component 6 includes a second connecting block 601. A number of second connecting blocks 601 are arrayed and fixedly connected to the adjacent surfaces of the two trolley bodies 4 on both sides. There is a connecting rod 602 between the two second connecting blocks 601 on both sides. One end of the connecting rod 602 is rotatably connected to one second connecting block 601, and the other second connecting block 601 and the inside of the connecting rod 602 are penetrated and fixedly connected with a screw nut 603. Specifically, after the device is transported into the tunnel 1, the end of the connecting rod 602 can be rotated into the second connecting block 601 on the other side, and the screw nut 603 is installed. The connecting rods 602 are fixedly connected in a crosswise manner in pairs to stabilize the device and prevent it from sliding left and right.

[0023] As Figure 1 shown, in some embodiments, a jacking and translation mechanism 7 is fixedly connected to the bottom ends of the struts on the adjacent sides of the two trolley bodies 4. Specifically, through the installed jacking and translation mechanism 7, it assists the device to move in the tunnel 1 and is removed after the connection component 6 is connected. The outer end brackets of the two trolleys jointly support the two trolleys.

[0024] As Figure 1 shown, in some embodiments, ladders 8 are fixedly connected to both sides of the trolley body 4. Specifically, through the installed ladders 8, it is convenient for the staff to climb onto the trolley body 4 to work.
