Technical Field

[0002] Elevator guide rails are key components that guide the elevator car and counterweight in vertical or tilting movements, directly determining the smoothness, safety, and comfort of elevator operation. They work in conjunction with guide shoes on the car and counterweight to limit lateral deviation, ensuring the elevator runs precisely along a fixed trajectory.

[0003] Currently, the alignment and positioning of guide rails during transportation mainly relies on manual adjustment. In traditional production, due to the large size and heavy weight of the guide rails, manual handling and positioning are not only labor-intensive and inefficient, but also prone to tilting due to operational errors. Furthermore, it is difficult to avoid the overlapping of preceding and subsequent guide rails, requiring continuous monitoring and adjustment by dedicated personnel, which significantly increases human resource costs.

[0004] Therefore, it is necessary to invent a roller-lifting elevator straight guide rail alignment and positioning mechanism to solve the above problems. Utility Model Content

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

Specifically, the guide rail lifting assembly 3 includes a lifting cylinder frame 31, a lifting cylinder 32 is installed inside the lifting cylinder frame 31, a roller frame 33 is connected to the output end of the lifting cylinder 32, a roller 34 is installed on the inner side of the top of the roller frame 33, and the rollers 34 on both sides are placed below both ends of the elevator straight guide rail 2. Specifically, the two-side guide rail alignment and positioning assembly 4 includes an alignment and positioning frame 41 set at the same straight position as the lifting cylinder frame 31. An alignment plate 42 is installed on one side of the alignment and positioning frame 41, and an alignment cylinder 43 is installed on the other side of the alignment and positioning frame 41. The alignment plate 42 is provided with mounting grooves 44 around its perimeter, and a positioning plate 45 is installed in the mounting grooves 44.

[0019] Specifically, one side of the guide rail alignment and positioning component 4 is a fixed structure and the other side is a driving structure. That is, the guide rail alignment and positioning component 4 on one side can drive the alignment plate 42 to move, and the alignment plate 42 in the guide rail alignment and positioning component 4 on the other side is fixedly connected to the alignment and positioning frame 41.

[0020] Specifically, the alignment positioning frame 41 is provided with mounting holes 411, and an alignment cylinder 43 is fixedly installed on one side of the mounting hole 411. The end of the alignment cylinder 43 is connected to the back of the alignment plate 42. Multiple positioning holes 412 are provided around the mounting hole 411, and positioning pins 46 are installed in the multiple positioning holes 412. The multiple positioning pins 46 together fix the alignment cylinder 43.

[0021] Specifically, the four sides of the push plate 42 are provided with mounting grooves 44, and the bottom sides of the mounting grooves 44 are provided with locking holes 441. The positioning plate 45 is fixed in the mounting groove 44, and the positioning plates 45 on opposite sides are installed at the same time. Adjacent positioning plates 45 cannot be installed at the same time.

[0022] Specifically, the positioning plate 45 is L-shaped in all aspects. The bottom sides of the positioning plate 45 are provided with telescopic grooves 451. A locking block 47 is installed in the telescopic groove 451. A locking spring 48 is installed between the bottom of the locking block 47 and the bottom of the telescopic groove 451. A limiting frame 452 is provided at the opening of the telescopic groove 451. A limiting strip 471 matching the limiting frame 452 is provided at the end edge of the locking block 47. The protruding part of the locking block 47 springs into the locking hole 441, and the moving surface of the locking block 47 is set as an inclined surface.

[0023] Specifically, the overall size of the locking block 47 does not exceed the internal size of the locking hole 441.

[0024] Specifically, the bottom of the roller frame 33 is provided with a vertical positioning column 35, which moves vertically at the top of the lifting cylinder frame 31.

[0025] In this embodiment, during the guide rail conveying stage, multiple elevator straight guide rails 2 to be positioned are placed on top of the guide rail transverse conveying frame 1. The guide rails are then conveyed to the output end, i.e., directly above the two side guide rail lifting components 3, through the power device of the conveying frame, thus completing the material preparation before positioning.

[0026] Specifically, the lifting cylinder 32 inside the lifting cylinder frame 31 is activated, and the output end of the cylinder drives the roller frame 33 to rise vertically. At this time, the rollers 34 on the inner side of the top of the roller frame 33 rise synchronously until the rollers 34 on both sides firmly support the bottom of both ends of the elevator straight guide rail 2. During this process, the vertical positioning column 35 at the bottom of the roller frame 33 moves vertically along the top of the lifting cylinder frame 31 to prevent the roller frame from shifting and ensure the stability of the lifting process.

[0027] In this embodiment, according to the specifications of the elevator straight guide rail 2, a positioning plate 45 is installed in the mounting groove 44 around the push plate 42. During installation, the locking block 47 in the telescopic groove 451 at the bottom of the positioning plate 45 will pop out under the elastic force of the locking spring 48, and its protruding part will pop into the locking hole 441 at the bottom of the mounting groove 44. At the same time, the limiting strip 471 and the limiting frame 452 cooperate to prevent the locking block from falling off, thereby realizing the quick fixing of the positioning plate.

[0028] Specifically, the alignment cylinder 43 is fixed by the mounting hole 411 on the alignment positioning frame 41, and is further reinforced by the positioning pins 46 in the surrounding positioning holes 412 to ensure stable operation of the cylinder. The end of the cylinder pushes the alignment plate 42 to move towards the fixed side until one side of the elevator straight guide rail 2 is in close contact with the positioning plate 45 on the fixed side alignment plate 42, thus completing the horizontal alignment and precise positioning of the guide rail.

[0029] Specifically, after positioning is completed, the drive-side push-aligning cylinder 43 is first controlled to reset, driving the push-aligning plate 42 back to the initial position; then the lifting cylinder 32 is controlled to retract, the roller frame 33 and roller 34 descend, and the positioned elevator straight guide rail 2 is placed back into the guide rail transverse conveyor frame 1. Finally, the conveyor frame transports the guide rail to the next process, completing one positioning cycle, which can be reused for the next batch of guide rails.

[0030] In this embodiment, the design of fixing the positioning component on one side and driving it on the other side, together with the precise limiting of the positioning plate 45, can control the horizontal offset of the guide rail to a very small range; at the same time, the vertical positioning column 35 ensures that there is no offset during the lifting process. The double protection ensures that the guide rail positioning error is low and meets the high precision requirements of elevator guide rail installation.

[0031] In this embodiment, by replacing the positioning plate 45 on the push-align plate 42, different specifications of elevator straight guide rails 2 can be adapted without replacing the entire push-align assembly; and the positioning plate adopts a spring locking structure, which makes installation and disassembly quick and convenient, reducing downtime when switching specifications.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
