Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pulley technology, and in particular relates to a pulley body with wear markings. Background Technology
[0002] Pulley bodies are mostly made of rolled and welded structure, with smooth rope groove surfaces and an attractive appearance. However, because there are no wear marks, when the pulley body is worn, operators can only measure the wear degree of the rope groove by comparing it with a template, which is inefficient. Moreover, inspectors need to get close to the inspection area to perform the measurement, which poses a safety hazard. During maintenance, only grease can be applied to the wire rope, leaving little grease in the rope groove, which leads to severe wear between the wire rope and the pulley groove. Utility Model Content
[0003] To address some or all of the technical problems existing in the prior art, this utility model provides a pulley body with wear markings, comprising a hub, spokes, rim, rope groove, and a detection component. The spokes are fitted onto the hub, the rim is disposed on the circumference of the spokes, the rope groove is formed in the center direction of the rim circumference, and the detection component is mounted on the rope groove for detecting the wear condition of the rope groove. The detection assembly includes an annular detection groove, detection holes, and detection rivets. The annular detection groove is symmetrically arranged around the inner wall of the rope groove at the most wear-prone area to detect the wear condition of the inner wall of the rope groove. The detection holes are evenly arranged along the circumferential direction of the bottom of the rope groove to detect the wear condition of the bottom of the rope groove. A countersunk hole is provided on the outer wall of the rope groove, and the detection rivets are inserted into the countersunk hole to detect the service life of the pulley.
[0004] Furthermore, in the pulley body with wear markings, the annular detection groove is arranged in an arc shape, and the depth of the annular detection groove is 20% of the thickness of the rope groove sidewall.
[0005] Furthermore, in the pulley body with wear markings mentioned above, there are two sets of detection holes, with three detection holes in each set. The depth of the middle detection hole in each set is H, and the depth of the other two detection holes is H / 2, where the depth H is 50% of the diameter of the steel wire rope used.
[0006] Furthermore, in the pulley body with wear marks mentioned above, four countersunk holes are evenly distributed on each side of the rope groove.
[0007] The pulley body with wear markings of this utility model has the following advantages and beneficial effects: This invention, through the setting of the detection component, allows for the determination of the wear degree of the pulley body by visually inspecting the wear marks when wear occurs in the rope groove. This results in high work efficiency, and the inspection personnel do not need to approach the inspection area, thus ensuring a high safety factor. At the same time, the annular detection groove and detection hole can store lubricating grease for wire rope lubrication, which can effectively reduce the wear between the wire rope and the pulley groove and extend the service life of the wire rope and pulley body.

[0008] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only for further understanding of the embodiments of the present invention and constitute a part of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. In the drawings: Figure 1 This is a schematic diagram of the overall structure of the pulley body with wear markings according to this utility model; Figure 2 for Figure 1 A magnified structural diagram of A in the middle; Figure 3 for Figure 2 Top view.
[0009] Explanation of reference numerals in the attached figures: 1: Hub; 2: Spoke; 3: Rim; 4: Rope groove; 41: Countersunk hole; 5: Detection component; 51: Annular detection groove; 52: Detection hole; 53: Detection rivet. Detailed Implementation
[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0011] like Figures 1 to 3 As shown, the pulley body with wear markings of this utility model includes a hub 1, spokes 2, rim 3, rope groove 4, and detection component 5. The spokes 2 are sleeved on the hub 1, the rim 3 is disposed on the circumference of the spokes 2, the rope groove 4 is opened in the center direction of the circumference of the rim 3, and the detection component 5 is installed on the rope groove 4 for detecting the wear condition of the rope groove 4. The detection component 5 includes an annular detection groove 51, a detection hole 52, and a detection rivet 53. The annular detection groove 51 is symmetrically arranged around the inner wall of the rope groove 4 at the most wear-prone area, and is used to detect the wear condition of the inner wall of the rope groove 4. The detection hole 52 is evenly arranged along the circumferential direction of the bottom of the rope groove 4, and is used to detect the wear condition of the bottom of the rope groove 4. A countersunk hole 41 is provided on the outer wall of the rope groove 4, and the detection rivet 53 is inserted into the countersunk hole 41 to detect the service life of the pulley.
[0012] Furthermore, in the pulley body with wear markings of this utility model, the annular detection groove 51 is arranged in an arc shape, and the depth of the annular detection groove 51 is 20% of the thickness of the side wall of the rope groove 4. When the rope groove 4 is worn, the wear degree of the entire rope groove 4 can be determined by observing the annular groove, such as uneven wear, side wear, local wear, etc. At the same time, the annular groove on the side wall of the rope groove 4 can also store some grease for lubrication of the wire rope and the two side walls of the rope groove 4, which can effectively alleviate the wear of the wire rope and the pulley rope groove 4 and extend the service life of the wire rope and the pulley body.
[0013] Furthermore, in the pulley body with wear markings of this utility model, there are two sets of detection holes 52, with three detection holes 52 in each set. The depth of the middle detection hole 52 in each set is H, and the depth of the other two detection holes 52 is H / 2. The depth H is 50% of the diameter of the steel wire rope used. During routine maintenance and inspection, the wear condition of the bottom of the rope groove 4 can be easily determined by observing whether each set of holes exists (and the number of holes). This is intuitive and convenient. At the same time, the detection holes 52 can also store some grease for lubrication of the steel wire rope and the bottom of the rope groove 4, which can effectively alleviate the wear of the steel wire rope and the pulley rope groove 4 and extend the service life of the steel wire rope and the pulley body.
[0014] Furthermore, in the pulley body with wear markings of this utility model, there are four countersunk holes 41 evenly distributed on each side of the rope groove 4. The detection rivets 53 installed in the countersunk holes 41 can be copper / aluminum rivets. When the wear reaches a certain level, the screws will show wear, and it can be visually determined whether the pulley needs to be replaced.
[0015] In summary, compared with the prior art, the pulley body with wear markings of this utility model has the following advantages and beneficial effects: This invention, through the setting of the detection component, allows for the determination of the wear degree of the pulley body by visually inspecting the wear marks when wear occurs in the rope groove. This results in high work efficiency, and the inspection personnel do not need to approach the inspection area, thus ensuring a high safety factor. At the same time, the annular detection groove and detection hole can store lubricating grease for wire rope lubrication, which can effectively reduce the wear between the wire rope and the pulley groove and extend the service life of the wire rope and pulley body.
