[0022] like Figure 1 As shown, an elevator guide rail fixing device comprises a fixing plate 1, two supporting plates 2 are fixedly installed on the front wall surface of the fixing plate 1, a mounting plate 3 is fixedly installed between the two supporting plates 2, two mounting holes 4 are provided on the mounting plate 3, a positioning component 5 for preventing bolt dislocation is arranged inside each mounting hole 4, two groups of limit components 6 corresponding to each other for fixing and adjusting the position of the positioning component 5 are arranged on the left and right sides of the mounting plate 3, and the limit components 6 on the left and right sides of the mounting plate 3 are distributed in a mirror image. It should be noted that the fixing plate 1 is first installed on the hoistway wall or beam by fasteners, and then each mounting is adjusted according to the width of the elevator guide rail. For the positioning components 5 inside the hole 4, the staff only needs to control the two groups of limit components 6 corresponding to each positioning component 5, so that each positioning component 5 can be adjusted inside the corresponding mounting hole 4, and each positioning component 5 can be fixed inside the corresponding mounting hole 4. When the elevator guide rail and the guide rail bracket are installed and fixed by fasteners, the bolts in the fasteners are passed through the positioning components 5 and then tightened with nuts. The bolts are restricted by the positioning components 5 to avoid loosening and dislocation of the bolts when subjected to a large impact, thereby solving the problem that the mounting holes 4 with elliptical structures cannot restrict the bolts like circular holes and leave no dislocation space.

[0023] like Figures 1 to 3As shown, the positioning assembly 5 includes two slide grooves 501, two sliders 502, a positioning ring 503, two first threaded holes 504, two first threaded rods 505, two circular holes 506 and two connecting rods 507. The inner side wall surface of each mounting hole 4 is provided with two upper and lower corresponding slide grooves 501, the interior of each slide groove 501 is movably installed with a slider 502, the middle of each adjacent slider 502 is fixedly installed with a positioning ring 503, the side wall surface of each slider 502 is provided with a first threaded hole 504, the interior of each first threaded hole 504 is threadedly connected with a first threaded rod 505, each first threaded rod 505 is movably installed in the corresponding slide groove 501, the interior of each slide groove 501 is provided with a circular hole 506 on the side away from the midpoint of the two mounting holes 4, the interior of each circular hole 506 is movably installed with a connecting rod 507, and each Each connecting rod 507 is fixedly connected to the adjacent first threaded rod 505. It should be noted that if two adjacent connecting rods 507 are rotated in the same direction at the same time, each connecting rod 507 will drive the corresponding first threaded rod 505 to rotate. At this time, the slider 502 corresponding to each first threaded rod 505 will slide inside the corresponding slide groove 501, and each two adjacent sliders 502 will jointly drive the positioning ring 503 to move. If two adjacent connecting rods 507 are rotated in the opposite direction at the same time, each connecting rod 507 will drive the corresponding first threaded rod 505 to rotate. At this time, the slider 502 corresponding to each first threaded rod 505 will slide in the opposite direction inside the corresponding slide groove 501, and each two adjacent sliders 502 will jointly drive the positioning ring 503 to move in the opposite direction, so that the positioning ring 503 can move left and right to meet the installation requirements of different guide rail widths.

[0024] like Figures 1 to 3 As shown, the positioning assembly 5 also includes two circular grooves 508 and two positioning rods 509. The inner side wall surface of each mounting hole 4 is provided with two corresponding circular grooves 508 on the left and right. A positioning rod 509 is movably installed inside each circular groove 508. One end of each positioning rod 509 close to the adjacent positioning ring 503 is fixedly connected to the positioning ring 503. It should be noted that when the positioning ring 503 moves to the leftmost end, the positioning rod 509 located on the left side of the positioning ring 503 will be snapped into the inside of the adjacent circular groove 508. When the positioning ring 503 moves to the rightmost end, the positioning rod 509 located on the right side of the positioning ring 503 will be snapped into the inside of the adjacent circular groove 508. Through the mutual cooperation of the circular grooves 508 and the positioning rods 509, the stability is highest when the positioning ring 503 moves to the leftmost and rightmost ends.

[0025] like Figure 1 , Figure 3As shown, the limiting assembly 6 includes a turntable 601, two rectangular blocks 602, two second threaded holes 603, two second threaded rods 604, two first nuts 605, an elliptical ring 606 and a cylindrical block 607, a turntable 601 is fixedly installed on the end of each connecting rod 507 away from the mounting plate 3, rectangular blocks 602 are arranged on the front and rear sides of each turntable 601, a side of each rectangular block 602 close to the mounting plate 3 is fixedly connected to the mounting plate 3, a second threaded hole 603 is provided on the side of each adjacent two rectangular blocks 602 close to each other, a second threaded rod 604 is arranged inside each second threaded hole 603, an elliptical ring 606 is fixedly installed in the middle of each adjacent two second threaded rods 604, and a first nut is threadedly connected to the end of each second threaded rod 604 away from the adjacent elliptical ring 606 605, each elliptical ring 606 is provided with a cylindrical block 607 inside, and each cylindrical block 607 is fixedly connected to the turntable 601 on one side close to the adjacent turntable 601.

When the rotation angle of the connecting rod 507 is reached, the first nuts 605 corresponding to the two second threaded rods 604 are rotated respectively, so that each first nut 605 is tightly attached to the adjacent rectangular block 602, thereby fixing the positions of the two second threaded rods 604 and completing the fixation of the connecting rod 507.

[0026] like Figure 3 As shown, the limit assembly 6 also includes a limit block 608. A limit block 608 is fixedly installed on the side of each cylindrical block 607 away from the adjacent turntable 601. It should be noted that the limit block 608 mainly plays a limiting role to prevent the elliptical ring 606 and the cylindrical block 607 from detaching.

[0027] like Figure 3 As shown, the limiting assembly 6 also includes two second nuts 609, and each second threaded rod 604 is threadedly connected to one end of the adjacent elliptical ring 606 with the second nut 609. It should be noted that when the positions of the two second threaded rods 604 need to be fixed, the positions of the two second threaded rods 604 can be further fixed by rotating the second nut 609 on each second threaded rod 604 so that each second nut 609 is tightly attached to the adjacent rectangular block 602.

[0028] In summary:

[0029] First, the fixing plate 1 is installed to the shaft wall or the crossbeam by means of fasteners, and then the positioning component 5 inside each mounting hole 4 is adjusted according to the width of the elevator guide rail. The staff only needs to control the two sets of limit components 6 corresponding to each positioning component 5 to adjust each positioning component 5 inside the corresponding mounting hole 4, and fix each positioning component 5 inside the corresponding mounting hole 4. When the elevator guide rail and the guide rail bracket are installed and fixed by means of fasteners, the bolts in the fasteners are passed through the positioning component 5 and then tightened with the nuts. The bolts are restricted by the positioning component 5 to avoid loosening and dislocation of the bolts when subjected to a large impact, thereby solving the problem that the mounting holes 4 with elliptical structures cannot restrict the bolts like circular holes and leave no dislocation space.
