Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels, and specifically to a guide wheel groove that can effectively prevent the steel wire rope from jumping out. Background Art

[0002] A guide wheel is a key component in a mechanical system. Guide wheels, also known as guide rollers or tracking wheels, are mechanical components designed to guide, support, and control the movement of an object along a predetermined path. Their main function is to ensure that the moving object can move in a predetermined direction and trajectory, while reducing friction and resistance during the movement. Guide wheels achieve the guidance and support of the moving object through their internal pulley structure or rolling elements (such as ball bearings, cylindrical rollers, etc.). These rolling elements can reduce the direct contact between the moving object and the surface it passes through, thereby reducing the friction coefficient and improving the movement efficiency. In an elevator, guide wheels are used to separate the spacing between the car and the counterweight, ensure the safe operation of the elevator, and increase the traction capacity in a rewound traction system.

[0003] After retrieval, the patent document (authorized announcement number CN218014930U) includes a guide wheel body. A plurality of equally spaced guide wheel grooves are provided on the outer circumferential side wall of the guide wheel body. A bearing sleeve is fixedly connected through the guide wheel body. A support shaft is arranged in the bearing sleeve. Two symmetrically arranged bearings are arranged between the support shaft and the bearing sleeve. A limiting mechanism for limiting the installation process of the bearing is arranged in the bearing sleeve. Two symmetrically arranged support frames are arranged on the side wall of the support shaft. The utility model first uses a "V"-shaped structure with a horizontal bottom to replace the traditional semi-circular structure, realizing automatic fine-tuning of the position and self-positioning during the wire drawing process, ensuring that the wire is in the best reasonable position, and replacing the traditional fixed-axis form of single-wheel with a bearing support method, facilitating the inspection and maintenance and replacement of bearings during use, and improving the service life of the guide wheel.

[0004] However, the above device still has deficiencies:

[0005] Some of the existing guide wheel grooves on the market are equipped with rope blocking parts during the elevator installation process. However, due to the damage caused by the movement of the steel wire rope, there is still a risk of the steel wire rope jumping out of the rope groove. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a guide wheel groove that can effectively prevent the steel wire rope from jumping out, solving the problem that some of the existing guide wheel grooves on the market are equipped with rope blocking parts during the elevator installation process, but due to the damage caused by the movement of the steel wire rope, there is still a risk of the steel wire rope jumping out of the rope groove.

[0007] To achieve the above object, the present utility model proposes a guide wheel groove that effectively prevents the steel wire rope from jumping out, including a guide wheel disc. Both sides of the guide wheel disc are fixedly connected with anti-detachment component protection shells. The inner side wall of the anti-detachment component protection shell is fixedly connected with an outer frame. A cavity is opened inside the outer frame. A driven shaft is rotatably connected inside the cavity. One end of the driven shaft disposed inside the outer frame has a limiting stop rod fixedly connected to its side wall. An annular groove is opened on the inner side of the outer frame. A control rod is slidably connected inside the annular groove. One end of the control rod disposed inside the outer frame is fixedly connected with a limiting plate. One end of the control rod disposed outside the anti-detachment component protection shell is fixedly connected with a pull ring. The limiting plate abuts against the limiting stop rod. A pushing spring is disposed at the bottom of the limiting plate. Both ends of the pushing spring are respectively fixedly connected to the outer frame and the limiting plate.

[0008] Preferably, a guide wheel groove is opened on the side wall of the guide wheel disc, and a guide rope is disposed inside the guide wheel groove.

[0009] Preferably, a wheel column is disposed below the guide wheel disc. An empty groove is opened at the top of the wheel column. The guide wheel disc is rotatably connected inside the empty groove. A rotating shaft penetrates through the inside of the guide wheel disc. Both ends of the rotating shaft penetrate through the side wall of the wheel column and extend to the outside thereof. Nuts are threadedly connected to both ends of the rotating shaft extending to the outside of the wheel column.

[0010] Preferably, an anti-detachment rod is fixedly connected to the side wall of the driven shaft. A baffle plate is fixedly connected to the side wall of the driven shaft. A torsion spring is fixedly connected to the side wall of the outer frame. Both ends of the torsion spring are respectively fixedly connected to the baffle plate and the baffle.

[0011] Preferably, a limiting groove is opened on each of the pair of anti-detachment component protection shells on the side close to each other. The anti-detachment rod is slidably connected inside the limiting groove.

[0012] Preferably, one end of the driven shaft is rotatably connected inside the cavity, and the other end of the driven shaft is rotatably connected to the inner side wall of the anti-detachment component protection shell.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] Through the settings of the outer frame and the anti-detachment rod, when the guide rope is placed in the guide wheel groove, since the driven shaft is rotatable, the guide rope can pass through a pair of anti-detachment rods at this time. After the guide rope is placed in the guide wheel groove, since the limit stop rod on the driven shaft is blocked by the limit plate, this causes the anti-detachment rod to only deflect towards the direction close to the guide wheel disc and cannot deflect away from the guide wheel disc, which can firmly fix the guide rope in the guide wheel groove and prevent it from falling off. When the guide rope needs to be taken out, the staff only needs to pull the pull ring. At this time, under the drive of the pull ring, the control rod moves, the limit plate falls off the contact with the limit stop rod, and the limit stop rod loses the contact of the limit plate, and the anti-detachment rod can deflect away from the guide wheel disc, thus achieving the effect of detachment.

[0015] The advantage of this design is that when installing the guide rope, the anti-detachment rod can facilitate the installation of the guide rope, and effectively prevent the guide rope from detaching from the guide wheel groove during use. When the guide rope needs to be taken out, only the pull ring needs to be pulled. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-5 As shown, a guide wheel groove that effectively prevents a wire rope from jumping out includes a guide wheel disc 1, a guide wheel groove 101 is opened on the side wall of the guide wheel disc 1, and a guide rope 24 is arranged inside the guide wheel groove 101.

[0024] A wheel column 2 is provided below the guide wheel disc 1, and an empty slot 21 is provided on the top of the wheel column 2. The guide wheel disc 1 is rotatably connected in the empty slot 21. A rotating shaft 22 is connected through the interior of the guide wheel disc 1. Both ends of the rotating shaft 22 pass through the side walls of the wheel column 2 and extend to the outside thereof. Both ends of the rotating shaft 22 extending to the outside of the wheel column 2 are threadedly connected with nuts 23.

[0025] Both sides of the guide wheel 1 are fixedly connected with an anti-falling component protection shell 3, the inner side wall of the anti-falling component protection shell 3 is fixedly connected with an outer frame 4, a cavity 401 is opened inside the outer frame 4, the inner part of the cavity 401 is rotatably connected with a driven shaft 42, and the side wall of the driven shaft 42 is fixedly connected with an anti-falling rod 421. When the guide rope 24 is placed in the guide wheel groove 101, since the driven shaft 42 is rotatable, the guide rope 24 can pass through a pair of anti-falling rods 421. The driven shaft 42 is fixedly connected to the side wall at one end of the outer frame 4. The positioning lever 5 and the inner side of the outer frame 4 are provided with an annular groove 501, and the inner side of the annular groove 501 is slidably connected to the operating lever 51, and one end of the operating lever 51 arranged in the outer frame 4 is fixedly connected to the limiting plate 52. When the guide rope 24 is placed in the guide wheel groove 101, the limiting lever 5 on the driven shaft 42 is blocked by the limiting plate 52, which causes the anti-falling rod 421 to be deflected only in the direction close to the guide wheel disc 1, but not in the direction away from the guide wheel disc 1, which can make the guide rope 24 firmly fixed in the guide wheel groove 101 to prevent it from falling off.

[0026] The operating rod 51 is arranged on one end outside the anti-falling component protection shell 3 and is fixedly connected to a pull ring 5101. The limit plate 52 conflicts with the limit stop rod 5. A push spring 53 is provided at the bottom of the limit plate 52. The two ends of the push spring 53 are respectively fixedly connected to the outer frame 4 and the limit plate 52. When the guide rope 24 needs to be taken out, the staff only needs to pull the pull ring 5101. At this time, the operating rod 51 moves under the drive of the pull ring 5101, and the limit plate 52 falls off and conflicts with the limit stop rod 5. The limit stop rod 5 loses the conflict with the limit plate 52, and the anti-falling rod 421 can be deflected in the direction away from the guide wheel 1, thereby achieving the effect of disengagement.

[0027] When installing the guide rope 24, the anti-detachment rod 421 facilitates the installation of the guide rope 24, and effectively prevents the guide rope 24 from detaching from the guide wheel groove 101 during use. When the guide rope 24 needs to be removed, only the pull ring 5101 needs to be pulled. The structure is simple and the operation is convenient.

[0028] A baffle 422 is fixedly connected to the side wall of the driven shaft 42, and a torsion spring 423 is fixedly connected to the side wall of the outer frame 4. The two ends of the torsion spring 423 are respectively fixedly connected to the shielding baffle 41 and the baffle 422. The torsion spring 423 provides the power required for the rotation of the driven shaft 42 and its restoration to the original position.

[0029] A pair of anti-detachment component protection housings 3 are each provided with a limiting groove 31 on the side close to each other, and the anti-detachment rod 421 is slidably connected in the limiting groove 31.

[0030] One end of the driven shaft 42 is rotatably connected in the cavity 401, and the other end of the driven shaft 42 is rotatably connected to the inner side wall of the anti-detachment component protection housing 3.

[0031] Working principle: When the guide rope 24 is placed into the guide wheel groove 101, since the driven shaft 42 is rotatable, at this time the guide rope 24 can pass through a pair of anti-detachment rods 421. After the guide rope 24 is placed into the guide wheel groove 101, since the limiting stop rod 5 on the driven shaft 42 is blocked by the limiting plate 52, this causes the anti-detachment rod 421 to only deflect towards the direction close to the guide wheel disc 1 and cannot deflect towards the direction away from the guide wheel disc 1. This can firmly fix the guide rope 24 in the guide wheel groove 101 and prevent it from falling off. When the guide rope 24 needs to be removed, the staff only needs to pull the pull ring 5101. At this time, under the drive of the pull ring 5101, the control rod 51 moves, the limiting plate 52 falls off the contact with the limiting stop rod 5, the limiting stop rod 5 loses the contact of the limiting plate 52, and the anti-detachment rod 421 can deflect towards the direction away from the guide wheel disc 1, thus achieving the effect of detachment.

[0032] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
