[0002] In the fields of construction, mining, rescue, etc., rope guides are often needed to guide, control and stabilize the movement of ropes, especially rope guides for bridge crane grab buckets. Existing rope guides have the following problems: if the lifting is tilted or slanted, the rope guides will be stuck with the fixed frames on both sides due to friction, and the wire rope will rub against the rope guide, causing burrs on the wire rope. These problems will affect the use effect and service life of the rope guide, so a new type of rope guide is needed to solve these problems. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a new rope guide which can avoid the friction and jamming of the rope guide wheel and the column pin fixing frames on both sides, the friction between the wire rope and the rope guide wheel, which causes burrs on the wire rope, shortens the service life of the wire rope and affects the use efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A novel rope guide comprises a rope guide wheel, wherein roller bearing grooves and thrust bearing grooves are provided on both sides of the rope guide wheel, the thrust bearing grooves are located outside the roller bearing grooves, roller bearings are installed in the roller bearing grooves, and thrust bearings are installed in the thrust bearing grooves.

[0006] Furthermore, the thrust bearing groove, the roller bearing groove and the guide rope pulley share a central axis.

[0007] Furthermore, the outer end surface of the thrust bearing extends out of the outer side surface of the guide rope pulley.

[0008] Furthermore, it also includes a fixing frame and a pin fixing frame, wherein the pin fixing frame is relatively arranged on the fixing frame, two groups of guide rope wheels are respectively fixedly installed on the pin fixing frame through roller bearings and pins, and a steel wire rope is arranged between the two groups of guide rope wheels.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By setting the thrust bearing groove to install the thrust bearing, it is possible to avoid the friction and jamming of the guide rope wheel and the column pin fixing frames on both sides, which will cause friction between the wire rope and the guide rope wheel, resulting in burrs on the wire rope, shortening the service life of the wire rope and affecting the efficiency of use. It has the advantages of simple structure, easy replacement and high stability, and can be widely used in construction, mining, rescue and other fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings and embodiments. 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.

[0019] Reference Figures 2 to 6 A new type of rope guide 204 includes a rope guide wheel 403, and roller bearing grooves 402 and thrust bearing grooves 401 are provided on both sides of the rope guide wheel 403. The thrust bearing groove 401 is located on the outside of the roller bearing groove 402, and a roller bearing 301 is installed in the roller bearing groove 402, and a thrust bearing 302 is installed in the thrust bearing groove 401.

[0020] In this embodiment, the thrust bearing groove 401, the roller bearing groove 402 and the guide rope wheel 403 share a central axis.

[0021] In this embodiment, the outer end surface of the thrust bearing 302 extends out of the outer side surface of the guide rope pulley 403, that is, the outer contour width of the two thrust bearings 302 after installation is greater than the width of the guide rope pulley 403.

[0022] In this embodiment, it also includes a fixed frame 201 and a pin fixed frame 202, wherein the pin fixed frame 202 is relatively arranged on the fixed frame 201, and two groups of guide rope wheels 403 are respectively fixedly installed on the pin fixed frame 202 through roller bearings 301 and pins 205, and a wire rope 203 is provided between the two groups of guide rope wheels 403.

[0023] Working principle:

[0024] When in use, firstly install the thrust bearing 302 in the thrust bearing groove 401 on the side of the guide rope wheel 403, install the roller bearing 301 on the guide rope wheel 403, and then fix the rope guide 204 on the column pin 205. It is necessary to ensure that the roller bearing 301 and the thrust bearing 302 are installed in place to ensure the stability and safety of use. In addition, it is also necessary to select wear-resistant guide rope wheel materials and high-strength column pin materials to improve service life and stability.
