Because each car has a large number of handrails, conventional installation requires measuring and marking with a tape measure for positioning, and visual inspection or using a string line to confirm the overall verticality of the handrails during installation. This process is tedious and prone to human error. Utility Model Content

[0003] This application aims to solve at least one of the technical problems in the background art by providing a positioning device for installing hanging rings in subway cars.

[0004] This application is achieved through the following technical solution:

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0035] like Figures 1-3 As shown in the figure, this application provides a positioning device for installing a hanging ring in a subway car, including a support rod 1, a support block 2, a positioning beam 3, a locking pin 5, and a positioning block 4.

[0036] The number of support rods 1 is at least two. In actual implementation, the number of support rods 1 can be configured as three, with the three support rods 1 arranged in parallel and spaced apart.

[0037] Support block 2 is connected to one end of support rod 1. Support block 2 has a support groove suitable for accommodating handrail crossbar 6. In actual operation, handrail crossbar 6 is placed in the support groove. The support blocks 2 on the three support rods 1 provide support force to the two ends and the middle of handrail crossbar 6, respectively. The support groove can be designed as an arc-shaped groove that adapts to the shape of handrail crossbar 6. The arc-shaped groove can form a large contact area with handrail crossbar 6, which can radially limit the handrail crossbar 6 and prevent the handrail crossbar 6 from rolling left and right during installation.

[0038] The positioning beam 3 is detachably connected to two support rods 1 at both ends. In the initial state, the positioning beam 3 can be connected to the middle support rod 1 and the left support rod 1. At this time, the positioning beam 3 corresponds to the left shaft section of the handrail crossbar 6. After the lifting ring 7 on the left shaft section is installed, the positioning beam 3 is removed and connected to the middle support rod 1 and the right support rod 1 to install the lifting ring 7 on the right shaft section of the handrail crossbar 6.

[0039] The locking pin 5 moves through the support rod 1 to engage with the central positioning hole on the handrail crossbar 6, thereby restricting the rotation of the handrail crossbar 6 around its own axis.

[0040] There are multiple positioning blocks 4, which are connected to the positioning beam 3 and arranged at intervals along the length of the positioning beam 3. The spacing between two adjacent positioning blocks 4 is adapted to the installation spacing of the lifting ring 7. The positioning block 4 has a positioning plane for fitting the end face of the assembly ring in the lifting ring 7. In the working state, when the handrail crossbar 6 is located in the support groove, the distance between the positioning block 4 and the handrail crossbar 6 is less than the thickness of the assembly ring in the lifting ring 7. That is, when the lifting ring 7 is moved axially along the handrail crossbar 6, the positioning block 4 can form mechanical interference with the lifting ring 7. When the end face of the assembly ring on the lifting ring 7 contacts the positioning plane, the lifting ring 7 is located in the predetermined installation position.

[0041] The positioning device for installing the handrail in the subway car provided in this application can support the handrail crossbar 6 through the support rod 1 and the support block 2, ensuring that the height of the handrail crossbar 6 remains unchanged during the installation of the handrail 7. The positioning beam 3 and the positioning block 4 can provide a positioning reference for the handrail 7. After the end face of the handrail 7 is aligned with the positioning plane of the positioning block 4, the predetermined installation position is reached, which can improve the convenience of the installation of the handrail 7. Moreover, the positioning accuracy of the handrail 7 in the length direction of the handrail crossbar is high. During the installation process, the positioning plane on the positioning block 4 can also serve as a positioning reference, avoiding radial tilting of the assembly ring during the installation process. Furthermore, the locking pin 5 prevents the handrail crossbar 6 from rotating around its own axis, thereby ensuring the accurate position of the handrail 7 after installation, that is, ensuring a good vertical effect between the handrail crossbar 6 and the bottom of the car after the handrail crossbar 6 is installed.

[0042] In some alternative embodiments, a support base plate 8 is connected to one end of the support rod 1 away from the support block 2.

[0043] In this embodiment of the application, by setting the support base plate 8, the support area of ​​the support rod 1 can be increased, thereby ensuring the stability of the support rod 1 and avoiding the occurrence of the support rod 1 tilting during the installation process.

[0044] In some alternative embodiments, the positioning block 4 has a positioning groove adapted to the handrail crossbar 6.

[0045] In this embodiment, the positioning groove can make way for the handrail crossbar 6. The positioning block 4 has a larger blocking area relative to the assembly ring of the hanging ring 7, which means that the assembly ring and the positioning surface have a larger contact area. This can improve the ease of operation during installation and ensure that the hanging ring 7 has better positional accuracy after installation.

[0046] In some optional embodiments, the positioning groove is an arc-shaped groove. In actual implementation, the diameter of the arc-shaped groove is adapted to the handrail crossbar 6, that is, the positioning groove can fit snugly against the handrail crossbar 6. The positioning block 4 can be configured as a nylon block, so that the positioning groove and the handrail crossbar 6 will have greater friction after fitting snugly. This will help ensure the relative positioning accuracy between the positioning block 4 and the handrail crossbar 6, and at the same time, it can avoid the positioning block 4 from damaging the surface of the handrail crossbar 6, thus ensuring the appearance integrity of the handrail crossbar 6.

[0047] In some alternative embodiments, the positioning block 4 is detachably connected to the positioning beam 3.

[0048] In this embodiment, the spacing between adjacent positioning blocks 4 can be adjusted according to different installation requirements, thereby improving the overall adaptability of the device. In actual implementation, the positioning blocks 4 can be connected to the positioning beam 3 by bolts, which on the one hand achieves detachability, and on the other hand ensures the connection stability between the positioning blocks 4 and the positioning beam 3.

[0049] In some optional embodiments, the support rod 1 includes a first plate, a second plate, and a third plate; the second plate is connected to the first plate, the surfaces of the first and second plates are perpendicular, and the length of the second plate is greater than that of the first plate; the third plate is connected to the first plate, the surfaces of the third plate and the first plate are perpendicular, and the length of the third plate is equal to that of the second plate; the first plate is located between the second and third plates; the first, second, and third plates together form a rod-shaped member with a U-shaped cross-section, which facilitates material sourcing, for example, the web of one end of a channel steel can be cut to a certain length to directly obtain the support rod 1; wherein, the ends of the first, second, and third plates form relief grooves, and the support block 2 is located in the relief grooves and connected to the second and third plates.

[0050] In some optional embodiments, the second plate and the third plate are respectively provided with positioning notches at one end, and the positioning beam 3 is respectively connected to positioning rods 9 that are suitable for cooperating with the positioning notches at both ends.

[0051] In this embodiment, the positioning rod 9 and the positioning notch can be directly placed to form a fit, which is convenient to operate.

[0052] In some alternative embodiments, the positioning rod 9 and the locking pin 5 are jointly fitted with a locking ring 10 to restrict the positioning rod 9 from moving away from the locking pin 5.

[0053] In actual implementation, a shoulder can be provided at the end of the locking pin 5 to axially limit the locking ring 10. When unlocking, the locking pin 5 can be pulled out directly to drive the locking ring 10 away from the positioning rod 9.

[0054] During installation, support rod 1 is placed in the predetermined position, the middle positioning hole on handrail crossbar 6 corresponds to the position of locking pin 5 on support rod 1, support block 2 supports handrail crossbar 6, locking pin 5 engages with the middle positioning hole shaft hole on handrail crossbar 6, positioning rod 9 on positioning beam 3 is placed in positioning notch, wherein there is a lifting ring 7 between every two positioning blocks 4, the positioning rod 9 and locking pin 5 are locked by locking ring 10, the axial sliding of lifting ring 7 makes lifting ring 7 contact with positioning block 4, and then the mounting ring on lifting ring 7 can be relatively fixed to handrail crossbar 6.

[0055] In some optional embodiments, positioning blocks 4 are installed on both the upper and lower sides of the positioning beam 3. Thus, after the lifting ring 7 on the left side of the handrail crossbar 6 is installed, it is only necessary to unlock the connection between the left end support rod 1 and the positioning beam 3, and then flip the positioning beam 3 to connect it with the right end support rod 1, which can further improve the convenience of operation.
