Description

Technical Field

[0001] This utility model relates to an auxiliary tool for the installation of rail transit vehicles, and more particularly to an auxiliary tool for the installation of windshield structures of rail transit vehicles. Background Technology

[0002] The windshield structure of rail transit vehicles is mainly located at both ends of the carriages, serving as a movable connection between two carriages. During windshield installation, the windshield mounting holes must be aligned with the car body mounting holes for proper installation and fixation. However, current windshield installation largely relies on manual positioning, which results in poor positioning accuracy. Excessive misalignment between the windshield screw mounting holes and the car body holes prevents windshield installation, necessitating hole enlargement or tapping to install the windshield fixing screws. This significantly reduces the quality of the windshield structure, increases labor costs, and leads to low installation efficiency and high operational difficulty. Utility Model Content

To this end, this invention proposes an auxiliary tool for installing windshield structures in rail transit vehicles, thereby improving the installation accuracy and efficiency of the windshield structure and reducing the difficulty of installation operations.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0005] An auxiliary tool for installing windshield structures on rail transit vehicles includes a gantry frame, which consists of left and right columns and a crossbeam located at the upper end of the left and right columns. The crossbeam is provided with a sliding groove, and a slider is installed in the sliding groove. The slider is vertically connected to a screw rod by a thread, and the bottom of the screw rod is connected to a hook by a flexible connection.

[0006] According to some embodiments of this utility model, the soft connection is a chain.

[0007] According to some embodiments of this utility model, the bottom of the screw is connected to the chain via a lifting ring.

[0008] According to some embodiments of this utility model, the lifting ring is a freely rotatable universal joint structure.

[0009] According to some embodiments of this utility model, a handle is connected to the upper end of the screw.

[0010] According to some embodiments of this utility model, support plates are provided at the bottom of the left and right columns.

[0011] According to some embodiments of the present invention, a rubber pad is provided at the bottom of the support sheet.

[0012] According to some embodiments of this utility model, the hook is L-shaped.

[0013] According to some embodiments of this utility model, a positioning groove is provided at the position where the hook contacts the bolt hole of the windshield structure.

[0014] According to some embodiments of this utility model, the left and right columns are fixed to the crossbeam by welding.

[0015] This utility model has at least the following beneficial effects: The installation of the windshield structure generally requires three auxiliary tools to work together. After adjusting the windshield structure upwards, leftwards, and rightwards, the bolt holes of the windshield structure can be aligned with the mounting holes of the vehicle body, so that the threads of the screws and screw holes can be installed in a corresponding manner. This reduces the risk of screw breakage or damage to screw holes caused by screw jamming during installation, thus reducing labor costs and material consumption. This product adopts a multi-degree-of-freedom adjustment mechanism to achieve movement in the XYZ three-axis directions to adapt to different installation environments, thereby improving the installation accuracy and efficiency of the windshield structure and reducing the difficulty of installation operations.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 An auxiliary tool for installing windshield structures in rail transit vehicles includes a gantry frame 1, which consists of left and right columns 11 and a crossbeam 12 mounted on the upper ends of the left and right columns 11. To ensure a more secure installation, the left and right columns 11 and the crossbeam 12 are welded together. The crossbeam 12 has a groove 121, within which a slider 2 is installed. The slider 2 is vertically connected to a screw 3 via a threaded connection. The bottom of the screw 3 is connected to a hook 5 via a flexible connection 4. The flexible connection 4 is a chain, but can be made of materials such as leather rope or steel wire depending on the actual needs. To facilitate the connection between the screw 3 and a lifting ring 6, the bottom of the screw 3 is connected to the chain via the lifting ring 6. To ensure free rotation of the chain, the lifting ring 6 is a freely rotatable universal joint structure. Additionally, a handle 31 is connected to the upper end of the screw 3 for easy rotation.

[0023] In order to provide a larger support area for the left and right columns 11, support plates 13 are provided at the bottom of the left and right columns 11. In order to prevent the left and right columns 11 from damaging the paint of the rail transit vehicle, rubber pads 14 are provided at the bottom of the support plates 13.

[0024] In addition, in order to facilitate the hook 5 to be attached to the bolt holes of the windshield structure, the hook 5 is L-shaped, and a positioning groove 51 is provided at the position where the hook 5 contacts the bolt holes of the windshield structure, so as to ensure that it is attached more firmly.

[0025] When using this product, first install one side of the windshield structure onto the carriage with bolts. Then, install the left and right uprights 11 on the walls of the two adjacent carriages respectively, and attach the hooks 5 to the bolt holes at the other end of the windshield structure. When it is necessary to control the windshield structure to move vertically, simply rotate the screw 3. The up-and-down movement of the screw 3 will drive the windshield structure to move vertically. When it is necessary to control the windshield structure to move horizontally, simply move the screw 3 to control the slider 2 to slide left and right in the slide groove 121, which will drive the windshield structure to move horizontally.

[0026] The installation of the windshield structure generally requires the coordinated operation of three auxiliary tools. Adjusting the windshield structure upwards, leftwards, and rightwards ensures that the bolt holes align with the mounting holes on the vehicle body. This allows for proper screw installation, reducing the risk of screw breakage or damage to the bolt holes due to jamming during installation, thus minimizing increased labor costs and material consumption. This product employs a multi-degree-of-freedom adjustment mechanism, enabling movement in the XYZ axes to adapt to different installation environments. This improves the installation accuracy and efficiency of the windshield structure while reducing the difficulty of the installation operation.
