[0047] The grabbing assembly 900 of the second telescopic assembly 800 of the tunnel steel arch installation trolley can grab the top steel arch 100, the first driving assembly 600 rotates the second telescopic assembly 800, that is, the top steel arch 100 changes from a horizontal state to a vertical state, and the first driving assembly 600 can be a hydraulic oil cylinder or other telescopic mechanism.

[0049] Reference Figure 7 In an optional embodiment, the rotating device 700 includes a rotating gear disc 703 and a rotating driving mechanism 701, the rotating gear disc 703 is rotationally arranged on the upper support plate 500, an upper hinge seat 704 is arranged at the upper end of the rotating gear disc 703, and the second telescopic assembly 800 is hinged on the upper hinge seat 704;

[0050] The rotary drive mechanism 701 is disposed on the lower end surface of the upper support plate 500, and the drive wheel 702 of the rotary drive mechanism 701 is located on the upper end surface of the upper support plate 500 and meshes with the rotary gear disk 703.

[0051] In some embodiments, the rotary drive mechanism 701 is generally a motor. The rotary drive mechanism 701 is disposed on the lower end surface of the upper support plate 500, and the drive shaft of the rotary drive mechanism 701 extends to the upper end of the upper support plate 500. A drive wheel 702 is disposed on the drive shaft of the rotary drive mechanism 701. The drive wheel 702 meshes with the rotary gear disk 703, thereby causing the rotary gear disk 703 to rotate. A second telescopic component 800 is disposed on the rotary gear disk 703, thereby causing the top steel arch 100 on the second telescopic component 800 to rotate, so that the top steel arch 100 and the bottom steel arch 200 are precisely aligned, ensuring better subsequent connection.

[0052] Reference Figure 5 In an optional embodiment, the second telescopic component 800 includes a rotating arm 801, which is hinged to the upper hinge seat 704; at least one telescopic mechanism 802 is provided on the rotating arm 801, and the gripping component 900 is provided on the telescopic mechanism 802.

[0053] In some embodiments, the second telescopic assembly 800 has a rotating arm 801, which is hinged to the upper hinge seat 704. A drive link 130 is hinged to the rotating arm 801, and the drive link 130 causes the rotating arm 801 to rotate from horizontal to vertical, thereby rotating the second telescopic assembly 800. One or more telescopic mechanisms 802 are provided on the rotating arm 801, and each telescopic mechanism 802 is provided with a gripping component 900. The telescopic mechanism 802 can raise and lower the gripping component 900.

[0054] In an optional embodiment, the gripping assembly 900 includes a gripping arm 901, on which a clamping groove 902 is provided, and clamping cylinders 903 are correspondingly provided on both sides of the clamping groove 902, and the movable end of the clamping cylinder 903 can extend into the clamping groove 902; the two clamping cylinders 903 cooperate to clamp the steel supply frame.

[0055] The gripping arm 901 has a clamping groove 902. The telescopic mechanism 802 moves the gripping arm 901 toward the top steel arch frame 100. After the clamping groove 902 clamps the top steel arch frame 100, the movable end of the clamping cylinder 903 moves toward the top steel arch frame 100 and abuts against the top steel arch frame 100, thereby clamping the top steel arch frame 100. When the second telescopic component 800 rotates, the top steel arch frame 100 will not detach from the gripping component 900.

[0056] In an optional embodiment, the rotating arm 801 is provided with three telescopic mechanisms 802, including one main telescopic mechanism 802 and two auxiliary telescopic mechanisms 802. The main telescopic mechanism 802 is perpendicular to the upper support plate 500, and the two auxiliary telescopic mechanisms 802 are symmetrically arranged on both sides of the main telescopic mechanism 802.

[0057] The rotating arm 801 is equipped with three telescopic mechanisms 802. The main telescopic mechanism 802 is perpendicular to the upper support plate 500, that is, the extension direction of the main telescopic mechanism 802 is in the same direction as the extension direction of the rotating arm 801. Auxiliary telescopic mechanisms 802 are symmetrically arranged on both sides of the main telescopic mechanism 802. The telescopic mechanism is generally a telescopic hydraulic cylinder.

[0058] Reference Figure 8 In an optional embodiment, a lifting mechanism 110 is provided at the end of the trolley body 300 away from the rotating device 700. The lifting mechanism 110 includes a side support plate 111 and a lifting drive assembly 112. The side support plate 111 is disposed on the trolley body 300, a guide assembly 113 is disposed on the side support plate 111, a lifting assembly is disposed on the guide assembly 113, and the lifting drive assembly 112 is disposed on the side support plate 111. The lifting drive assembly 112 is used to raise and lower the lifting assembly.

[0059] The segmented steel arch frame is divided into a top steel arch frame 100 and a bottom steel arch frame 200. One top steel arch frame 100 needs to be connected to two bottom steel arch frames 200. After the segmented steel arch frame is manufactured in the factory, it is transported to the tunnel entrance. The bottom steel arch frame 200 is first installed manually and then fixed to both sides of the tunnel.

[0060] The first drive assembly 600 on the trolley body 300 causes the second telescopic assembly 800 to be placed horizontally; when the trolley body 300 moves toward the horizontally placed top steel arch 100, the lifting assembly can be inserted below the top steel arch 100; then the lifting drive assembly 112 causes the lifting assembly to move upward along the guide assembly 113, so that the lifting assembly raises the top steel arch 100.

[0061] In an optional embodiment, the guide assembly 113 includes at least two guide rods, and the guide rods extend along the height direction of the side support plate 111;

[0062] The lifting assembly includes a drive arm 114 and at least one lifting arm 115. The guide rod passes through the drive arm 114, and the lifting drive assembly 112 is connected to the drive arm 114. The lifting drive assembly 112 causes the drive arm 114 to rise and fall.

[0063] The lifting arm 115 is mounted on the drive arm 114, and a lifting arm 117 is mounted on the lifting arm 115. A third lifting assembly 116 is provided between the lifting arm 117 and the lifting arm 115, and the third lifting assembly 116 causes the lifting arm 117 to rise and fall.

[0064] Two lifting arms 115 are generally installed on the drive arm 114, and a lifting arm 117 is installed on the lifting arm 115. In order to facilitate the gripping component 900 to grip the top steel arch frame 100, the lifting arm 117 is raised and lowered by the third lifting component 116. Since the top steel arch frame 100 is located on the lifting arm 117, when the lifting arm 117 is raised, the top steel arch frame 100 is raised, that is, the top steel arch frame 100 corresponds to the clamping groove 902 of the gripping arm 901, so that the clamping groove 902 can clamp the top steel arch frame 100. The two clamping cylinders 903 cooperate to clamp the top steel arch frame 100, thereby fixing the top steel arch frame 100 in the clamping groove 902.

[0065] Reference Figure 2 In an optional embodiment, the first lifting assembly 120 includes a plurality of lifting cylinders, which are mounted on the trolley body 300, and the movable end of the lifting cylinder is connected to the first moving assembly 400.

[0066] When the first drive assembly 600 rotates the second telescopic assembly 800 to a position perpendicular to the upper support plate 500, the height of the top steel arch frame 100 needs to be adjusted. The lifting cylinder of the first lifting assembly 120 causes the first moving assembly 400 to rise and fall, thereby realizing the adjustment of the height of the top steel arch frame 100.

[0067] In an optional embodiment, the first moving component 400 includes a lower support plate 401 and an upper moving plate 402. The lower support plate 401 is disposed on the first lifting component 120. A lower guide component 403 and a lower drive component 406 are disposed on the lower support plate 401. The lower guide component 403 is used to guide the upper moving plate 402 to move along a first direction, and the lower drive component 406 is used to cause the upper moving plate 402 to reciprocate along the first direction.

[0068] In an optional embodiment, the upper moving plate 402 is provided with an upper guide component 404 and an upper drive component 405, the lower guide component 403 is used to guide the upper support plate 500 to move along the second direction, and the upper drive component 405 is used to make the upper support plate 500 reciprocate along the second direction.

[0069] The upper guide assembly 404 and the lower guide assembly 403 have the same structure, generally both being guide rails and sliders; taking the lower guide assembly 403 as an example, at least two guide rails are provided on the lower support plate 401, and two sliders are slidably provided on each guide rail, with the sliders fixed to the lower end face of the upper moving plate 402.

[0070] The lower drive assembly 406 can be a servo motor, and a linear bearing is provided on the lead screw of the servo motor. The linear bearing is located on the upper moving plate 402. In this way, the lower drive assembly 406 and the lower guide assembly 403 cooperate to move the upper moving plate 402 along the first direction. The upper drive assembly 405 and the upper guide assembly 404 cooperate to move the upper support plate 500 along the second direction. The first moving assembly 400 realizes the horizontal adjustment of the top steel arch frame 100. In cooperation with the first lifting assembly 120 and the rotating device 700, the top steel arch frame 100 is precisely adjusted, thereby making the top steel arch frame 100 and the bottom steel arch frame 200 more precisely connected.

[0071] The second telescopic component 800 of the tunnel steel arch frame installation trolley is in a horizontal position, and the lifting component is lowered to its lowest point. The trolley body 300 moves forward, and the lifting component is inserted into the lower end of the top steel arch frame 100. The lifting drive component 112 raises the lifting component. The third lifting component 116 raises the lifting arm 117, aligning the top steel arch frame 100 with the clamping slot 902 of the gripping arm 901 of the gripping component 900. The telescopic mechanism 802 moves the gripping arm 901 toward the top steel arch frame 100 and clamps the top steel arch frame 100 with the clamping slot 902. Two clamping cylinders 903 cooperate to clamp the top steel arch frame 100, thereby fixing the top steel arch frame 100. The trolley body 300 moves to the designated position, and the first drive component 600 rotates the second telescopic component 800, that is, the second telescopic component 800 drives the top steel arch frame 100 to rotate and fix it, so that the top steel arch frame 100 is in a vertical position.

[0072] Then, the position of the top steel arch frame 100 is precisely adjusted by the first moving component 400 and the rotating assembly so that the top steel arch frame 100 corresponds to the bottom steel arch frame 200, thus realizing the erection of the steel arch frame.

[0073] The tunnel steel arch frame installation trolley can automatically grab the top steel arch frame 100 and flip it for installation, greatly reducing manual intervention. After the segmented steel arch frames are prefabricated in the factory and transported to the construction site, the tunnel steel arch frame installation trolley can transport the steel arch frames into the tunnel and complete the installation. It has both transportation and installation functions. The whole process can be completed with the help of a small number of construction personnel, reducing labor intensity and labor costs.

[0074] The installation efficiency of tunnel steel arch frame installation trolleys is far higher than that of traditional manual installation methods, allowing for the completion of a large amount of installation work in a short time. Furthermore, because tunnel steel arch frame installation trolleys can install heavier steel arch frames, the sections of the steel arch frames can be longer during factory prefabrication, effectively reducing the number of installation joints. Fewer joints result in better overall stability of the steel arch frame and faster installation progress.

[0075] The tunnel steel arch frame installation trolley provided by the present invention has a second telescopic component 800 on the upper support plate 500 of the trolley body 300. The gripping component 900 of the second telescopic component 800 can grip the top steel arch frame 100. The first driving component 600 can rotate the second telescopic component 800 and position it vertically to the upper support plate 500. The first lifting component 120 can raise and lower the upper support plate 500, thereby adjusting the height of the top steel arch frame 100. Combined with the first moving component 400, the upper support plate 500 can be moved in the horizontal plane. The rotating device 700 can rotate the second telescopic component 800 within a certain range, thereby enabling the top steel arch frame 100 to accurately correspond with the bottom steel arch frame 200. This can improve the installation accuracy of the top steel arch frame 100 and the bottom steel arch frame 200 and improve the erection efficiency of the steel arch frame.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
