Technical Field

[0001] The present invention relates to the field of subway train maintenance, and particularly to an installation fixture for an R-shaped sealing strip of a subway train door. Background Art

[0002] After the subway door has been used for a long time, the sealing strip will age, so the sealing strip needs to be replaced. During the operation, the traditional manual method of replacing the sealing strip has low efficiency and can no longer meet the requirements. Moreover, the long-term installation of the sealing strip will cause physical exhaustion of the staff, and the working intensity is relatively high, affecting the installation quality.

[0003] Therefore, it is necessary to design some automated devices for installing the sealing strip. However, since the mainstream sealing strip of the subway door is an R-shaped sealing strip and there is a cavity in the sealing, general fixtures can cause deformation at the cavity during clamping, so the installation effect is not good.

[0020] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and gives the detailed implementation manners and specific operation processes, but the protection scope of the present invention is not limited to the following embodiments.

[0021] An installation fixture for an R-shaped sealing strip of a subway train door, as Figure 1 and Figure 2 shown, includes a fixture body and a support block. The support block 8 is shaped to fit the cavity of the sealing strip 9. After the support block 8 is placed in the cavity, the fixture body clamps the sealing strip 9.

[0022] The fixture body includes a bottom plate 1, a first support plate 3, a second support plate 11, a first extrusion module, and a second extrusion module. The first extrusion module is installed on the first support plate 3, and the second extrusion module is installed on the second support plate 11, clamping the sealing strip 9 by extruding it from both sides respectively.

[0023] The first extrusion module includes a first pressing plate 10 and two first rotating handles 2. The first pressing plate 10 is provided with first pressing plate guiding columns 5 for maintaining the moving direction. The first pressing plate guiding columns 5 pass through the first support plate 3, and a first blocking gasket 4 is provided at the other end of the first pressing plate guiding columns 5. A first spring 6 for resetting is sleeved on the first pressing plate guiding columns 5, and the first spring 6 is supported by the first blocking gasket 4 and the first support plate 3. The first rotating handle 2 drives the first pressing plate 10 to move towards the sealing strip 9 by passing through the first support plate 3.

[0024] There are two first pressing plate guiding columns 5, first blocking gaskets 4, and first springs 6 respectively.

[0025] The first rotating handle 2 includes a threaded rod fixed to the first support plate 3 and a pressing block sleeved on the threaded rod and mating with the threaded rod through threads. A pressing block mating portion is also provided at one end of the first pressing plate guiding column 5 where the first blocking gasket 4 is located. The pressing block drives the first pressing plate 10 after rotating closer to the pressing block mating portion.

[0026] In another embodiment of the present application, the second extrusion module includes a second pressing plate 7 and two second rotating handles 12. The second pressing plate 7 is provided with second pressing plate guiding columns 13 for maintaining the moving direction. The second pressing plate guiding columns 13 pass through the second support plate 14, and a second blocking gasket 15 is provided at the other end of the second pressing plate guiding columns 13. A second spring 14 for resetting is sleeved on the second pressing plate guiding columns 13, and the second spring 14 is supported by the second blocking gasket 15 and the second support plate 11. The second rotating handle 12 drives the second pressing plate 7 to move towards the sealing strip 9 by passing through the second support plate 11.

[0027] There are two second pressing plate guiding columns 13, second blocking gaskets 15, and second springs 14 respectively.

[0028] The second rotating handle 12 includes a threaded rod fixed to the second support plate 11 and a pressing block sleeved on the threaded rod and mating with the threaded rod through threads. A pressing block mating portion is further provided at one end of the second pressing plate guide post 13 located at the second blocking gasket 15. After the pressing block rotates, it approaches the pressing block mating portion to drive the second pressing plate 7.

[0029] Place the sealing strip 9 on the first pressing plate 10. Since the sealing strip 9 has a cavity, an additional support block 8 needs to be placed to support the pressure. The knob handle and the support plate are threadedly connected. By rotating the four knob handles, the ends of the knob handles generate pressure acting on the second pressing plate and the first pressing plate. The pressing plates squeeze the sealing strip 9. Anti-slip grooves are provided on the surfaces of the pressing plates and the support block 8 to increase the friction. The fixture clamps the sealing strip 9 and moves to complete the installation of the sealing strip. After the sealing strip is installed, rotate the four knob handles in the reverse direction, and the elastic force generated by the spring causes the pressing plates to loosen, completing the loosening of the fixture. During the clamping and loosening processes of the fixture, the pressing plate guide posts can ensure that the pressing plates do not shift. At the same time, the elastic force generated by the spring causes the pressing plates to always generate an outward tension, facilitating the insertion and removal of the sealing strip 9.
