[0002] Under the background of the dual-carbon strategy and Beautiful China, prefabricated linings are often mentioned or applied in the construction process of open-cut tunnels due to their characteristics of resource conservation, low carbon and environmental protection. As a new technology, prefabricated tunnels are gradually emerging. However, large-volume prefabricated components such as prefabricated tunnels often require a trolley for auxiliary installation. Traditional lifting devices have poor docking accuracy, low stability and low construction efficiency, and cannot meet the requirements of high precision and high construction efficiency of prefabricated tunnels. Therefore, corresponding improvements need to be made, and a device suitable for docking large-volume and heavy prefabricated components of prefabricated tunnels with a trolley is proposed to solve the above technical problems. However, this prefabricated component needs to be docked with the prefabricated tunnel of the prefabricated tunnel first, and then connected to the trolley. This prefabricated component is often made of high-strength steel and has a large self-gravity. The method of manual handling has poor feasibility and low construction efficiency. An installation device needs to be designed for it to improve its installation efficiency. Content of the Utility Model

[0020] As Figures 1 to 4 shown,

[0021] A transfer device for assembled precast tunnel connection blocks, comprising a tunnel precast segment 1, a precast component 2 detachably connected to the inner surface of the inner circle of the tunnel precast segment 1, and a transfer device 3 for transferring the precast component 2. The tunnel precast segment 1 is in a semi-circular ring shape (as Figure 1 shown), the transfer device 3 includes a support main body and a support plate 301 arranged on the support main body and used for supporting the precast component 2. The support plate 301 is arranged along the width direction of the tunnel precast segment 1, and one side surface of the support plate 301 is hinged to the upper surface of the support main body. The side surface of the support plate 301 away from the support main body is detachably connected to the precast component 2 by bolts. The support main body includes a base 302 and a support frame 303 movably arranged on the upper surface of the base 302 in the vertical direction. The upper surface of the support frame 303 is hinged to the support plate 301. A driving member 4 for driving the support frame 303 to move vertically is connected to the upper surface of the base 302, and a moving mechanism 304 for driving the base 302 to move is connected to the base 302;

[0022] Among them, a plurality of sleeves 6 matched with the precast component 2 are embedded in the tunnel precast segment 1. The plurality of sleeves 6 are respectively evenly spaced on one side of the inner circle of the tunnel precast segment 1. One end of the sleeve 6 protrudes out of the tunnel precast segment 1. Threads are provided in each sleeve 6. One side surface of each precast component 2 is arc-shaped and abuts against the inner surface of the tunnel precast segment 1. Through holes corresponding to the sleeves 6 are provided on the surface of the precast component 2. The precast component 2 and the sleeve 6 are detachably connected by bolts, and a circular manhole 7 communicating with its interior is provided on the side surface of the precast structure 2, which is convenient for workers to install bolts;

[0023] Two driving members 4 are provided on the upper surface of each base 302. The two driving members 4 are symmetrically arranged about the vertical axis of the base 302. The driving member 4 is a hydraulic telescopic cylinder and is arranged vertically. The telescopic end of each driving member 4 is fixedly connected to the support frame 303, and the driving member 4 is fixedly connected to the surface of the base 302 by bolts; Each moving mechanism 304 includes four universal wheels circumferentially spaced on the lower surface of the base 302. Of course, the universal wheels can also be electrically driven to facilitate the movement of the base 302.

[0024] As shown in the figure, the precast segment 1 of this tunnel is the vault part of the tunnel and is usually vertically placed on the ground. When it is necessary to transport and install the precast member 2 on the surface of the tunnel precast segment 1, first, the precast member 2 is placed on the upper surface of the support plate 301 by a hoisting device, and the two are fixedly connected by bolts. Subsequently, it is moved to one side of the inner circle of the tunnel precast segment 1 through the transfer device 3. Then, the driving member 4 is controlled to adjust the height of the support plate 301 so that the precast member 2 abuts against the inner circle surface of the tunnel precast segment 1, and the through holes on the surface of the precast member 2 are aligned with the sleeves 6 on the tunnel precast segment 1 one by one. Subsequently, the precast member 2 and the sleeve 6 are fixedly connected by bolts, so that the precast member 2 and the tunnel precast segment 1 are fixedly connected. Finally, the bolts between the support plate 301 and the precast member 2 are removed, and the transfer device 3 is moved to another place again to install one precast member 2; thus, the installation of the precast member 2 and the precast tunnel segment 1 can be completed, effectively improving the installation efficiency of the precast member 2. The precast member 2 can be quickly moved to the inside of the tunnel precast segment 1 through the transfer device 3, and the docking position of the precast member 2 and the sleeve 6 can be vertically moved through the driving member 4, which also improves the automation degree of the construction process.

[0025] In this embodiment, two telescopic rods 5 are provided between the surface of the support plate 301 on the side far from the tunnel precast segment 1 in the horizontal plane and the support frame 303. One end of each telescopic rod 5 is hinged to the upper surface of the support frame 303, and the other end is hinged to the surface of the support plate 301. The surface of the support plate 301 in contact with the precast member 2 is a special-shaped structural surface and fits with the precast member 2. The specific shape of the support plate 301 is combined Figure 3 as shown.

[0026] By means of the two telescopic rods 5, the inclination angle of the support frame 303 in the vertical plane can be changed, and then the angle of the precast member 2 during installation can be changed, which can effectively increase the movement range of the precast member 2, so that when the precast member 2 is docked with the precast tunnel segment, it can adapt to docking at different positions within a certain range, effectively improving the applicable range and working efficiency of this device.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
