[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0024] Embodiment 1:

[0025] like Figure 1 , 2As shown, the utility model provides a lining trolley for highway tunnel construction, including a mobile trolley 11 and a forming template 21, the forming template 21 is located above the mobile trolley 11, and multiple groups of support components are arranged on the mobile trolley 11, one end of which is in contact with the inner wall of the forming template 21, providing reliable support and stable support for the forming template 21. The forming template 21 can maintain a good shape and stability during the construction process, ensuring that the pouring of concrete can be carried out according to the predetermined requirements, thereby ensuring the quality of the tunnel lining. A support frame 12 is arranged above the mobile trolley 11, and the support frame 12 is connected to the mobile trolley 11 by bolts, ensuring the reliability and stability of the connection between the two, and can withstand large external forces and loads, so that the support frame 12 will not easily loosen or shift during the working process. Multiple groups of first electric hydraulic rods 31 are installed on the support frame 12, adding powerful power and adjustment capabilities to the entire system. Each group of first electric hydraulic rods 31 has control performance and can perform telescopic actions according to actual needs, thereby realizing the push and support of the inner wall of the forming template 21. When the first electric hydraulic rod 31 is extended and retracted, one end of the first electric hydraulic rod 31 will contact the inner wall of the forming template 21. It not only provides direct support force to ensure that the forming template 21 can maintain a stable shape and position, but also can flexibly adjust the state of the forming template 21 through the extension and retraction of the electric hydraulic rod. Through the cooperation of the first electric hydraulic rod 31 and the support assembly, during the construction process, according to different tunnel size and shape requirements, the first electric hydraulic rod 31 and the support assembly can be controlled to achieve fine adjustment of the forming template 21 to achieve the best construction effect.

[0026] like Figure 2 , 5 As shown in Figure 6, the support assembly includes an electric pulley 41, a plurality of mounting grooves 13 are provided on the mobile trolley 11, the slide rail 22 is clamped in the mounting groove 13, and is connected to the mobile trolley 11 by bolts, ensuring the stability and reliability of the slide rail 22 on the mobile trolley 11, and will not easily become loose or shifted. The electric pulley 41 is clamped in the slide rail 22, so that the electric pulley 41 can slide smoothly on the slide rail 22. Through this sliding connection, a connection relationship is established between the support assembly and the mobile trolley 11. When position adjustment or movement is required, the electric pulley 41 can slide freely along the slide rail 22, thereby driving the entire support assembly to move accordingly on the mobile trolley 11. This sliding connection not only provides flexibility and operability for the support assembly, but also enables the entire system to be more adaptable to different construction conditions and requirements. In the actual construction process, by controlling the sliding of the electric pulley 41, the position of the support assembly can be adjusted to meet the construction requirements of tunnel linings of different sizes.

[0027] The support assembly also includes a second electric hydraulic rod 42, a connecting plate 43 is arranged on the electric pulley 41, and one end of the second electric hydraulic rod 42 is connected to the connecting plate 43, so as to realize the effective linkage between the electric pulley 41 and the second electric hydraulic rod 42, so that the operation of the whole system is more coordinated and smooth, and the respective functions can be better exerted. The other end of the second electric hydraulic rod 42 is provided with a first rubber plate 44, and the first rubber plate 44 can play a good buffering role. When the second electric hydraulic rod 42 pushes or contacts the forming template 21, the first rubber plate 44 can effectively reduce the impact force and collision force, protect the second electric hydraulic rod 42 and the forming template 21 itself, and avoid damage or failure caused by direct collision. Secondly, the first rubber plate 44 can also play a certain anti-slip role. In the process of contacting with the forming template 21, the friction force is increased, so that the connection between the second electric hydraulic rod 42 and the forming template 21 is more stable and reliable, and the sliding or displacement during the working process is prevented. At the same time, the contact between the first rubber plate 44 and the forming template 21 also provides direct support and driving force for the forming template 21. Through the telescopic action of the second electric hydraulic rod 42, the magnitude and direction of the force applied to the forming template 21 can be controlled, so as to better adapt to different construction requirements and conditions.

[0028] Slide blocks 23 are provided on both sides of the slide rail 22, and slide grooves 47 are provided on the electric pulley 41 corresponding to the slide blocks 23, so that the slide blocks 23 can be stuck in the slide grooves 47. When the electric pulley 41 moves on the slide rail 22, the cooperation between the slide grooves 47 and the slide blocks 23 can ensure the smoothness and safety of the movement, and prevent the electric pulley 41 from leaving the track of the slide rail 22. At the same time, in order to further ensure the stability and safety of the slide rail 22 during operation, limit plates are installed at both ends of the slide rail 22. These limit plates play an important role in limiting the movement range of the electric pulley 41, preventing it from excessively moving and causing accidents. A plurality of reinforcing plates 14 are provided on the mobile trolley 11, and the slide rail 22 is located above the reinforcing plates 14, so that the slide rail 22 can be better supported and fixed.

[0029] like Figure 2 , 4As shown, a second rubber sheet 32 ​​is provided at one end of the first electric hydraulic rod 31, and the second rubber sheet 32 ​​contacts the forming template 21, and the second rubber sheet 32 ​​can play a good buffering effect. When the first electric hydraulic rod 31 pushes or applies force, the second rubber sheet 32 ​​can effectively reduce the impact force, avoid causing hard damage to the forming template 21, and also increase the friction during contact, so that the push or support is more stable and reliable. A convex block 15 is provided at one end of the mobile trolley 11, and a card slot 34 is provided on the traction member 33, and the convex block 15 can be just stuck in the card slot 34. The traction member 33 and the convex block 15 are both provided with connecting holes. By inserting the connecting bolts into these connecting holes, the traction member 33 and the convex block 15 are rotatably connected, and the traction member 33 can adjust the angle and direction as needed to adapt to different working scenes and operation requirements. The traction member 33 is connected with other mobile devices to realize the movement of the mobile trolley 11.

[0030] Embodiment 2:

[0031] Based on the lining trolley for highway tunnel construction provided in the first embodiment of the present application, the second embodiment of the present application proposes a lining trolley for highway tunnel construction. This second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present utility model will be further described below.

[0032] like Figure 3 As shown, the support assembly also includes a second electric hydraulic rod 42, a connecting plate 43 is provided on the electric pulley 41, one end of the second electric hydraulic rod 42 is connected to the connecting plate 43, and the effective linkage between the electric pulley 41 and the second electric hydraulic rod 42 is realized, so that the operation of the whole system is more coordinated and smooth, and the respective functions can be better exerted. The other end of the second electric hydraulic rod 42 is provided with a fixing plate 45. Support plates 46 are provided on both sides of the mobile trolley 11, and the two groups of support assemblies are connected to one group of support plates 46 through the fixing plate 45. The support plate 46 contacts the inner wall of the forming template 21, providing strong support and stable guarantee for the forming template 21. The second electric hydraulic rod 42 realizes the supporting function of the forming template 21 through the support plate 46, ensuring that the forming template 21 can obtain balanced support force at all parts, avoiding deformation or damage caused by uneven local force. The uniformly applied force can make the forming template 21 more stably maintain its shape and structure, providing a reliable foundation for the subsequent process.

[0033] The difference between the second embodiment and the first embodiment is that both sets of support components are connected to the support plate 46 through the fixing plate 45 provided at one end of the second electric hydraulic rod 42. When the second electric hydraulic rod 42 starts to operate and generates force, the force can be effectively transmitted to the support plate 46, and the support plate 46 is in direct contact with the forming template 21, so that the force generated by the second electric hydraulic rod 42 can be applied to the forming template 21 in a uniform manner. A series of problems that may be caused by uneven force are avoided. If the force cannot be evenly distributed on the forming template 21, it is easy to cause excessive or insufficient force in the local area. The area with excessive local force may bear too much pressure, thereby causing deformation or even damage; while the area with too little local force may not be able to get enough support, affecting the stability and reliability of the entire forming template 21. The force generated by the second electric hydraulic rod 42 can be more evenly dispersed to various parts of the forming template 21 through the support plate 46, and the forming template 21 can obtain relatively balanced support and force, effectively avoiding the risk of deformation or damage caused by uneven local force. The remaining conditions are the same as those in the first embodiment, so they will not be described in detail in this embodiment.

[0034] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
