Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1 - Figure 4 The utility model provides an elevator guide wheel installation device, comprising a guide wheel body 1 and a rotating bearing 2 fixedly installed therein;

[0029] A wheel axle 3 is fixedly mounted on the inner ring of the rotating bearing 2, and mounting mechanisms are provided at both ends of the wheel axle 3;

[0030] An oil storage cylinder 4 containing lubricant is symmetrically arranged on both sides of the guide wheel body 1, and an oil guide pipe 5 with a conical oil outlet end facing the rotating bearing 2 is fixedly installed at the bottom of the oil storage cylinder 4. The lubricant is divided into lubricating oil or lubricating grease, which can be selected according to needs;

[0031] A piston block 6 slidably connected to the oil storage cylinder 4 and sliding along the height direction thereof;

[0032] and a reciprocating mechanism disposed in the oil storage cylinder 4 and driving the piston block 6 to move intermittently when the guide wheel body 1 rotates;

[0033] The reciprocating mechanism includes a rotating roller 7 which passes through and is rotatably connected to the end face of the guide wheel body 1, a movable rod 8 which is fixedly mounted on the top of the piston block 6 and slides with the oil storage cylinder 4, a triangular extrusion block 9 which is fixedly connected to the top of the movable rod 8 and cooperates with the rotating roller 7, and a spring 10 which is sleeved on the surface of the movable rod 8, and the two ends of the spring 10 are respectively connected to the oil storage cylinder 4 and the triangular extrusion block 9.

[0034] The technical solution provided by this embodiment is as follows: when in use, the guide wheel body 1 is installed on the elevator fixed beam through the installation mechanism to achieve the function of installing the guide wheel body 1. When the guide wheel body 1 rotates, it can drive the rotating roller 7 to intermittently squeeze the triangular extrusion block 9 downward, so that the triangular extrusion block 9 drives the movable rod 8 and the piston block 6 to intermittently move downward to squeeze the spring 10, so that the piston block 6 moves downward to squeeze the lubricant in the oil storage cylinder 4, and the lubricant is discharged through the oil guide pipe 5 and sprayed into the rotating bearing 2. When the rotating roller 7 is separated from the triangular extrusion block 9, the spring 10 drives the piston block 6 to move up and reset, and the excess lubricant in the oil guide pipe 5 is sucked into the oil storage cylinder 4 to achieve the purpose of saving. Therefore, the lubricant is squeezed out by the intermittent movement of the piston block 6, so that the guide wheel body 1 automatically lubricates the rotating bearing 2 when it rotates, avoiding the situation that the personnel manually lubricates and easily forgets to lubricate, reducing the labor of the personnel, ensuring the use effect of the guide wheel body 1, and effectively improving the convenience of use and the service life of the guide wheel body 1.

[0036] Specifically, when adding lubricant to the oil storage cylinder 4, the sealing cap is rotated to open the oil filling pipe 11, and then the lubricant is pumped into the oil storage cylinder 4 through the oil filling pipe 11. After adding, the sealing cap is screwed onto the oil filling pipe 11, so as to achieve the effect of adding lubricant.

[0037] Furthermore, the mounting mechanism includes a mounting block 12 arranged at the bottom of the two end surfaces of the wheel axle 3, and an arc-shaped fixing block 13 installed on the top of the mounting block 12 by bolts. An arc-shaped groove is opened on the top of the mounting block 12, and the wheel axle 3 is installed between the arc-shaped groove and the arc-shaped fixing block 13. The oil storage cylinder 4 is fixed to the outer surface of the arc-shaped fixing block 13 through a base block.

[0038] Connecting ear plates are fixedly mounted on both sides of the mounting block 12, and connecting holes are formed on the tops of the connecting ear plates.

[0039] Specifically, when installing the guide wheel body 1, the connecting bolts are passed through the connecting holes on the connecting ear plates and connected to the fixed beams on the elevator to fix the mounting block 12. The wheel axle 3 is then placed on the mounting block 12, and the arc-shaped fixing block 13 is covered on the wheel axle 3 and connected to the mounting block 12 via bolts, thereby achieving the purpose of installing the guide wheel body 1.

The connecting frame 16 is rotatably connected to the bottom end of the adjusting screw 15.

[0044] The technical solution provided by this embodiment is: when in use, the steel wire is wound around the guide wheel body 1, and then the adjusting screw 15 is rotated to drive the connecting frame 16 to move downward, and drive the guide rod 17 to slide, so that the limiting wheel 18 is in contact with the guide wheel body 1, so that under the action of the limiting wheel 18, the steel wire wound around the guide wheel body 1 can be limited and blocked to prevent the steel wire from accidentally detaching from the guide wheel body 1, and the distance between the limiting wheel 18 and the guide wheel body 1 can be adjusted by the adjusting screw 15, so as to facilitate the use of steel wire ropes of different thicknesses.
