DETAILED DESCRIPTION

[0033] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0034] like Figures 1 to 7 As shown, the utility model proposes an assembled subway station side wall installation translation device, including a base 1, a platform 3, a first drive device 2, a guide wheel assembly 4, a second drive device 5, and a power device 6.

[0035] like Figure 2As shown, the base 1 includes a rectangular frame structure 11 formed by welding a plurality of thickened I-beams. The rectangular frame structure 11 also has a plurality of reinforcing ribs 12 fixedly welded thereto to increase the bearing capacity of the translation device mounted on the side wall. The power device 6 is mounted on one of the reinforcing ribs 12 .

[0036] The platform 3 is arranged on the upper part of the base 1 and is slidably connected to the base 1 through a sliding assembly. A rectangular frame structure formed by welding a plurality of thickened I-shaped steels is arranged inside the platform 3. A rectangular plate having the same length as the side length of the rectangular frame structure is arranged on both sides of the flange of the I-shaped steel to surround the I-shaped steel. A rectangular plate having the same area as the rectangle is arranged on the top of the upper flange of the I-shaped steel to form a platform surface. A slider 31 is arranged at the bottom of the lower flange of the I-shaped steel.

[0037] Two baffles 32 are also arranged in parallel on the upper part of the platform 3. Figure 1 As shown, the baffle 32 is fixedly connected to the front and rear ends of the platform 3, and is used to block the side wall of the subway station so that the bottom of the side wall is confined within the platform 3, thereby improving installation safety.

[0038] The sliding assembly includes a slider 31 and two parallel rails 13. The slider 31 is fixed to the bottom of the platform 3, and the rails 13 are fixed to the top of the base 1. The slider 31 is located between the two rails 13. In this way, the slider 31 can play a fixing role when the platform 3 slides along the rails 13 to ensure that the movement direction of the platform 3 does not deviate. Specifically, the slider 31 can be connected to the platform 3 by welding, or fixed to the bottom of the platform 3 by screw connection, and the rails 13 can be fixed to the base 1 by welding, or fixed to the top of the base 1 by screw connection.

[0039] The first driving device 2 has one end connected to the platform 3 and the other end connected to the base 1 through the first supporting member 21 , and is used for driving the platform 3 to move along the length direction of the base 1 .

[0040] The guide wheel assembly 4 is located in the base 1. The guide wheel assembly 4 can be selected from existing guide wheel assemblies 4, and the specific model and bearing capacity can be selected according to actual needs.

[0041] The second driving device 5 is connected to the guide wheel assembly 4 at one end and to the base 1 through the second support member 51 at the other end, and is used to drive the guide wheel assembly 4 to move along the height direction of the base 1 to achieve the extension or retraction of the guide wheel assembly 4.

[0042] The power device 6 is installed on the base 1 , specifically on the reinforcing rib 12 . The power device 6 is connected to the first driving device 2 and the second driving device 5 , respectively, and is used to provide power to the first driving device 2 and the second driving device 5 .

[0043] Specifically, the first driving device 2 and the second driving device 5 are both configured as hydraulic cylinders, and the power device 6 is configured as a hydraulic pump station.

[0044] It should be noted that the control principle of the hydraulic pump station providing power to the hydraulic cylinder is a technical principle well known to those skilled in the art. Its specific parameters and working principles can be set according to actual conditions and will not be elaborated here.

[0045] Further, if Figure 1 As shown, in this embodiment, the extended end of the first driving device 2 is connected to the side of the platform 3, the fixed end of the first driving device is connected to the first support member 21, and the first support member 21 is connected to the base 1. There are two first driving devices 2, which are arranged in parallel.

[0046] The first support member 21 is configured as a right-angled triangular steel block, one right-angled side of the right-angled triangular steel block is fixedly connected to the first driving device 2 , and the other right-angled side of the right-angled triangular steel block is welded to the base 1 .

[0047] Further, if Figure 2 , 4 As shown, in this embodiment, the extended end of the second driving device 5 is connected to the guide wheel assembly 4, the fixed end of the second driving device 5 is connected to the second support member 51, and the second support member 51 is connected to the base 1. The second driving device 5, i.e., the hydraulic cylinder, moves, and the piston rod of the hydraulic cylinder is extended and retracted, driving the guide wheel assembly 4 connected to the piston rod to achieve lifting and lowering. When the side wall installation translation device needs to move, the guide wheel assembly 4 is in a lowered state. When the side wall installation translation device is in place, the guide wheel assembly 4 is lifted, and the base 1 directly contacts the ground, thereby increasing the bearing capacity of the side wall installation translation device and enhancing safety and stability.

[0048] The second support member 51 is configured as a plate-like structure, one end of which is fixedly connected to the web steel of the base 1, the web steel being the vertical side wall of the I-beam, and the fixed connection method may be welding or other existing connection methods. The plate-like structure is arranged parallel to the bottom surface of the base 1, that is, it is also arranged perpendicular to the web steel, and the second drive device 5 is installed on the upper part of the other end of the plate-like structure, and the protruding end of the second drive device 5 passes through the plate-like structure and is fixedly connected to the guide wheel assembly 4.

[0049] like Figure 3 As shown, in this embodiment, the number of the guide wheel assemblies 4 is four.

[0050] like Figure 5 , 6 As shown, the working process of this embodiment is as follows:

[0051] First, the side wall installation translation device of the present invention is placed on the horizontal cushion layer 9. When in place, the second driving device 5 drives the guide wheel assembly 4 to lift inward, and the guide wheel assembly 4 is retracted, and the base 1 directly contacts the ground.

[0052] Secondly, the side wall is lowered from the gap between the lateral supports 10 to the platform 3 of the side wall installation translation device through the gantry crane hook 8.

[0053] Then, the gantry crane hook 8 is released, and the first driving device 2 is used to telescopically drive the platform 3 to move, thereby driving the subway station side wall 7 to move close to the previous ring assembly position.

[0054] Then, the gantry crane hook 8 is installed to lift the subway station side wall 7 by 20 to 30 cm.

[0055] Finally, the second driving device 5 drives the guide wheel assembly 4 to extend downward, and the guide wheel assembly 4 descends to contact the ground and drives the base 1 to leave the ground, withdraw the side wall installation translation device, and lower the subway station side wall 7, and the assembly is completed.

[0056] The device occupies a small area, has fast assembly and movement, and is easy to operate. When used in conjunction with a gantry crane, it can effectively replace the function of a trolley, increase assembly speed, and reduce construction costs.

[0057] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
