Description

Technical Field

[0001] This utility model relates to the field of flipping mechanism technology, specifically a bidirectional flipping mechanism for the end of elevator guide rail processing. Background Technology

[0002] The bidirectional flipping mechanism at the end of the elevator guide rail is a device specifically designed for flipping elevator guide rails during the production process. This device is mainly used to enable rapid and precise flipping of elevator guide rails between different surfaces, so that each surface of the guide rail can be processed, including but not limited to spraying, cutting, grinding, welding, etc.

[0003] When the bidirectional flipping mechanism at the end of the elevator guide rail is used for spraying, fixing the spraying angle can ensure that the paint contacts the guide rail surface at the optimal angle and distance during the spraying process, thereby improving the uniformity of the coating.

[0004] When the end bidirectional flipping mechanism for elevator guide rail processing sprays the guide rail, because the complete guide rail is too long, it is necessary to spray multiple sections of the cut guide rail separately before welding. During the spraying process, the spraying of the paint is uncontrollable due to the influence of the external environment, and the paint sprayed on the guide rail surface is fluid. This will cause the welding surface of the guide rail to be contaminated with paint. During welding, the presence of paint will cause uneven heating and cooling of the weld metal, increase welding stress, form cracks, and affect the strength of the weld. Therefore, to address the above problems, an end bidirectional flipping mechanism for elevator guide rail processing is proposed. Utility Model Content

A rectangular block 38 is fixedly connected to one end of the threaded rod 36. A threaded groove 39 is opened on the inner side of the rectangular block 38. The long rod assembly 4 includes a rotating long rod 41. A large gear 42 is fixedly connected to the outer side of the rotating long rod 41. A right limiting block 43 is rotatably connected to the outer side of the rotating long rod 41. The rotating block assembly 35 includes a rotating block 351. A sponge block 352 is fixedly connected to the inner side of the rotating block 351. A gasket 353 is fixedly connected to one side of the sponge block 352.

[0026] As a further implementation of this solution, the outer side of the rotating roller 25 is in contact with the inner side of the sliding groove 23. Several rotating rollers 25 are provided, and each rotating roller 25 is parallel to each other. The included angle between the rotating roller 25 and the support frame 21 is 90°. This design can strengthen the mutual fixation between components and improve the stability of the product.

[0027] As a further implementation of this scheme, the central axis of the handwheel lever 31 and the central axis of the long gear 32 are on the same straight line, the included angle between the handwheel lever 31 and the left limiting block 33 is 90°, and the machine tool 1 is slidably connected to the outside of the left limiting block 33. This design is conducive to the transmission of force between the device components.

[0028] As a further implementation of this solution, a handwheel lever 31 is fixedly connected to one side of the rotating block 351. The rotating block 351 and the handwheel lever 31 are on the same axis. The outer side of the rotating block 351 is in contact with the inner side of the rotating block assembly 35. The rotating block 351, the sponge block 352 and the pad 353 are on the same axis. This design is more reasonable and strengthens the wedge fit between the components.

[0029] As a further implementation of this solution, the included angle between the threaded rod 36 and the left limiting block 33 is 90°, the nut 37 and the left limiting block 33 are parallel to each other, and the projection of the rectangular block 38 in the vertical direction is a rectangle. This design is more reasonable and can avoid mutual obstruction between the components.

[0030] As a further implementation of this scheme, several sliding grooves 23 are provided, and each sliding groove 23 is parallel to each other. The angle between the return spring 24 and the support frame 21 is 90°. Several return springs 24 are provided, and each return spring 24 corresponds to a sliding groove 23. This design can ensure the effective operation of the device and improve the operating efficiency of the device.

[0031] As a further implementation of this scheme, the central axis of the rotating long rod 41 and the central axis of the large gear 42 are on the same straight line. One side of the large gear 42 meshes with the long gear 32, and the outer side of the rotating long rod 41 is spirally fitted with the inner side of the threaded groove 39. The right limit block 43 and the left limit block 33 are parallel to each other. This design is more reasonable, which is conducive to the mutual cooperation between components and improves the working efficiency of the device.

[0032] Working process: During operation, rotating the handwheel 31 drives the long gear 32 to rotate. When the long gear 32 rotates, it drives the meshing large gear 42 to rotate. When the large gear 42 rotates, it drives the rotating long rod 41 to rotate inside the threaded groove 39. The rotating long rod 41 is restricted by the rectangular block 38 and slides inside the machine tool 1. When the rotating long rod 41 moves a certain distance, it drives the right limit block 43 to move. At this time, the guide rail is placed on the rotating roller 25. After the right limit block 43 moves a certain distance, it will clamp the guide rail together with the rotating block assembly 35. Then, rotating the handwheel 31 drives the rotating block assembly 35 to rotate. When the rotating block assembly 35 rotates, it drives the clamped guide rail to rotate. The rotating guide rail squeezes the rotating roller 25, causing the rotating roller 25 to slide. The inner side of the groove 23 slides downward, while the right limit block 43 drives the rotating block assembly 35 to move through the guide rail. The movement of the rotating block assembly 35 drives the left limit block 33 to slide inside the machine tool 1. Rotate the nut 37 to make the nut 37 fit with the left limit block 33. The left limit block 33 will drive the rectangular block 38 to move through the nut 37. If the handwheel lever 31 is rotated in the opposite direction, the handwheel lever 31 drives the rotating block assembly 35 to rotate. At the same time, the left limit block 33 drives the right limit block 43 to move through the guide rail, realizing the bidirectional flipping of the guide rail end. The nozzle 22 will spray the guide rail surface in all directions. Since the end face of the guide rail is in contact with the gasket 353, it can avoid being sprayed. The paint sprayed onto the gasket 353 will also be absorbed by the sponge block 352, avoiding the paint on the welded end face of the guide rail from affecting the welding quality.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
