The opposite ends of the two sets of lead screws pass through bearings to the outside of the mounting plate and are fixed with knobs. The bottom end of the threaded block slides through the bottom end of the mounting plate and is fixed to the top of the clamping plate.

[0008] A further improvement is that a square fitting block is fixed at the end of the rotating shaft away from the grooved wheel, and a square fitting groove adapted to the square fitting block is provided on the clamping plate.

[0009] A further improvement is that the elastic ejection mechanism includes a sliding rod that slides through the mounting plate and a pull ring fixed to the top of the sliding rod.

[0016] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0017] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides an elevator guide wheel device, including an installation plate 1 installed in the elevator shaft and clamping plates 2 slidably disposed on the left and right sides of the bottom end of the installation plate 1. The two sets of clamping plates 2 are driven by the spacing adjustment mechanism inside the installation plate 1 and move in opposite directions. A grooved wheel 3 is provided between the two sets of clamping plates 2. The grooved wheel 3 has a groove for the elevator wire rope to pass through and limit and guide the wire rope. The left and right side walls of the grooved wheel 3 are rotatably connected to the rotating shaft 4 through the bearing. The end of the rotating shaft 4 away from the grooved wheel 3 is engaged with the clamping plate 2, so that the grooved wheel 3 can be clamped between the two sets of clamping plates 2. The two sets of clamping plates 2 are driven to move by the spacing adjustment mechanism to clamp the grooved wheel 3, so that the grooved wheel 3 is easy to disassemble and assemble, and can be easily replaced after long-term use. Below the mounting plate 1, a limiting pressure roller 5 is connected via an elastic ejection mechanism. The limiting pressure roller 5 is compatible with the grooved wheel 3 and can further limit the wire rope in conjunction with the grooved wheel 3. Hollow mounting seats 6 are welded and fixed at the four corners of the top of the mounting plate 1. The top of the mounting seat 6 is provided with an L-shaped mounting block 7, and the L-shaped mounting block 7 is fixed to the mounting seat 6 by an elastic snap-fit ​​mechanism. The L-shaped mounting block 7 is threaded with a mounting bolt 8, which fixes the L-shaped mounting block 7 in the elevator shaft, thus fixing the elevator guide wheel device in the elevator shaft. By symmetrically fixing the mounting seats 6 at the top of the mounting plate 1 and using the elastic snap-fit ​​mechanism to snap-fit ​​the mounting seats 6 and the L-shaped mounting blocks 7, the mounting plate 1 is easy to install and remove.

[0018] The spacing adjustment mechanism includes a lead screw 9 and a threaded block 10. The lead screw 9 has two sets and is rotatably connected to the left and right sides of the mounting plate 1 through bearings. The threaded block 10 has two sets and is threaded onto the lead screw 9. The opposite ends of the two sets of lead screw 9 pass through the bearings to the outside of the mounting plate 1 and are fixed with knobs 11 by bolts. The bottom end of the threaded block 10 slides through the bottom end of the mounting plate 1 and is fixed to the top end of the clamping plate 2 by bolts. By rotating the knob 11, the lead screw 9 is driven to rotate, so that the threaded block 10 threaded on the lead screw 9 drives the clamping plate 2 to move horizontally.

[0019] A square fitting block 12 is fixed at the end of the rotating shaft 4 away from the grooved wheel 3. A square fitting groove 13 is provided on the clamping plate 2, and the square fitting groove 13 is adapted to the square fitting block 12. When the two sets of clamping plates 2 move towards each other, the square fitting block 12 is embedded in the square fitting groove 13, realizing the fitting and insertion between the rotating shaft 4 and the clamping plate 2.

[0020] The elastic ejection mechanism includes a slide rod 14 and a pull ring 15. The slide rod 14 slides through the center of the mounting plate 1. The pull ring 15 is welded and fixed to the top of the slide rod 14. The bottom of the slide rod 14 slides through to the bottom of the mounting plate 1 and is fixed to a concave frame 16 by bolts. A limiting pressure roller 5 is rotatably connected to the inside of the concave frame 16 through a bearing. The limiting pressure roller 5 has a groove adapted to the wire rope. A cavity 17 is formed in the center of the mounting plate 1. A baffle 18 is fixedly sleeved on one side of the slide rod 14 located in the cavity 17. A first limiting spring 19 is fixed to the top of the baffle 18 and sleeved around the slide rod 14. The top of the first limiting spring 19 is fixedly connected to the top of the inner side of the cavity 17. Limiting rods 20 are welded and fixed on both the left and right sides of the top of the concave frame 16. Limiting holes 21 are symmetrically opened on the mounting plate 1, and the limiting holes 21 are adapted to the limiting rods 20. The upper part of the limiting rod 20 slides through into the limiting hole 21. Through the cooperation of the limiting hole 21 and the limiting rod 20, the concave frame 16 is limited, making it more stable during the lifting and lowering process.

[0021] The flexible locking mechanism includes a slot 22 and a flexible pin 23. The slot 22 is formed inside the mounting base 6. The flexible pin 23 slides through the side wall of the mounting base 6 and extends into the slot 22. An insert plate 24 is fixed to the bottom of the L-shaped mounting block 7. A through hole adapted to the insert plate 24 is formed at the top of the mounting base 6, allowing the insert plate 24 to slide into the slot 22. An insertion hole 25 is formed on the insert plate 24, and the insertion hole 25 is adapted to the flexible pin 23. The insert plate 24 is engaged by inserting the flexible pin 23 into the insertion hole 25. The positioning and locking mechanism is used to fix the mounting base 6 and the L-shaped mounting block 7. The elastic pin 23 is fixedly sleeved with a spring plate 26 on one side of the slot 22. A second limiting spring 27 is connected between the inner wall of the slot 22 away from the insert plate 24 and the spring plate 26. The second limiting spring 27 is movably sleeved around the elastic pin 23. The second limiting spring 27 provides an elastic push force to the spring plate 26, thereby enabling the elastic pin 23 to have an automatic springback function and automatically insert into the insertion hole 25.

[0022] In actual use, the elevator guide wheel device is fixed in the elevator shaft by mounting bolts 8. The elevator wire rope passes through the groove on the groove wheel 3 and is pressed and limited by the limiting pressure wheel 5. When the groove wheel 3 needs to be replaced after a long period of use, the two sets of clamping plates 2 are first driven to move to the left and right sides respectively by the spacing adjustment mechanism, so that the spacing between the two sets of clamping plates 2 is widened until the clamping plates 2 and the rotating shaft 4 are separated, thus realizing the convenient disassembly of the groove wheel 3. Then, the new groove wheel 3 is placed between the two sets of clamping plates 2. Next, the two sets of clamping plates 2 are driven to move towards each other by the spacing adjustment mechanism, so that the spacing between the two sets of clamping plates 2 is narrowed until the rotating shaft 4 is fitted into the clamping plates 2, so that the new groove wheel 3 is clamped between the two sets of clamping plates 2, thus realizing the convenient disassembly and replacement of the groove wheel 3. When the entire device needs to be disassembled, the elastic snap-fit ​​mechanism can be used to release the snap-fit ​​between the mounting base 6 and the L-shaped mounting block 7, allowing the mounting plate 1 to be directly removed from the bottom of the L-shaped mounting block 7 for quick disassembly and maintenance. During installation, first align the mounting base 6 at the top of the mounting plate 1 with the bottom of the L-shaped mounting block 7, and then use the elastic snap-fit ​​mechanism to snap the mounting base 6 and the L-shaped mounting block 7 together to complete the quick installation.
