Abstract
A detachable ground carrying roller comprises a roller cover, a roller body, a retainer ring, a fixed screw, a central shaft, a snap ring and a bearing, wherein the central shaft is provided with a roller body outside in a freely sliding way, both ends of the central shaft are exposed out of the roller body and supported on the bracket of the ground carrying roller. Both ends of the roller body are matched with the central shaft 5 and provided with retainer rings, out of which the central shaft is provided with the snap ring in a fastening way, and the end of the roller body is provided with a screw hole for fixing which is screwed with a set screw. The center of the roller body end inside the retainer ring is provided with the bearing supported on the central shaft. The outer surface of the roller body is provided with the roller cover in an assembling way, and the assembling way is a way of connecting each section of the roller cover for ensuring that once any section of the roller cover is damaged, and the damaged single section can be replaced. The utility model has the advantages of simple detaching and installing, replacing and maintaining, which can greatly save manpower, material resources and financial resources for users.
Description
Technical field:
The utility model relates to the ground carrying roller that steel rope supports usefulness, relates in particular to carrying roller removably.
Background technology:
The general Steel cable pulley that uses in mine mainly is the holder rope roller with unsplit casing of cast iron, cast steel or compound rubber material.Because the heavy tension of steel rope, often a local location on carrying roller grinds groove, causes holding in the palm scrapping of rope roller along with the intensification of wearing and tearing groove, and necessary brand new carrying roller of integral replacing causes very big waste.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of carrying roller removably is provided, can change according to the wear pattern of reality, the integral part of maintenance carrying roller remains valid and continues and uses, both can cut the waste, can guarantee the normal use of ground carrying roller again better.
Carrying roller removably described in the utility model, including roller shell, roll body, back-up ring, fix screw, center shaft, snap ring and bearing forms, center shaft is the main component of carrying roller removably described in the utility model, the center shaft outside is provided with and is provided with roll body to be free to slide form, expose outside the two ends of roll body at the two ends of center shaft, and two axial ends is used to be supported on the support of ground carrying roller.Matching with center shaft in the two ends of roll body, is provided with back-up ring, on the center shaft of the outside of back-up ring, is provided with snap ring with the form of clamping.In order to guarantee the stable of back-up ring, the roll body end is provided with the fixedly screw of usefulness, is screwed with fix screw in the screw.The center of the inboard roll body end of back-up ring is provided with the bearing that is supported on the center shaft.The outside of roll body is provided with roller shell with array configuration, and said array configuration is the array configuration that adopts into joint, is damaged to guarantee in a single day roller shell that arbitrary single-unit takes place, can immediately the roller shell single-unit of corrupted be changed.Because such replacing is simple, the time of changing operation is short, and material consumption is few.
Use carrying roller removably described in the utility model, can prolong to greatest extent service life of ground carrying roller, material is fully used, can solve effectively that localized wear takes place carrying roller and must integral body change the problem of a carrying roller.Learn that through experiment can reach the three-to-four-fold of present commercially available ground carrying roller the service life of carrying roller removably described in the utility model.The utility model adopts the detouchable sectional construction, comprises center shaft, back-up ring and roll body, can make the best use of everything, and dismounting and easy for installation helps changing and safeguarding, can save human and material resources and financial resources in large quantities for the user.
Description of drawings:
Accompanying drawing is the structural representation of carrying roller removably described in the utility model.Accompanying drawing 1 is a single-piece semi-sictional view structural representation; Accompanying drawing 2 is structural representations of side-looking.1-roller shell, 2-roll body, 3-back-up ring, 4-fix screw, 5-center shaft, 6-snap ring, 7-bearing
The specific embodiment:
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: carrying roller removably described in the utility model, including roller shell 1, roll body 2, back-up ring 3, fix screw 4, center shaft 5, snap ring 6 and bearing 7 forms, center shaft 5 is main components of carrying roller removably described in the utility model, center shaft 5 outsides are provided with to be free to slide the roll body 2 that form is provided with, expose outside the two ends of roll body 2 at the two ends of center shaft 5, and the two axial ends of center shaft 5 is used to be supported on the support of ground carrying roller.Matching with center shaft 5 in the two ends of roll body 2, is provided with back-up ring 3, on the center shaft 5 of the outside of back-up ring 3, is provided with snap ring 6 with the form of clamping.In order to guarantee the stable of back-up ring 3, roll body 2 ends are provided with the fixedly screw of usefulness, are screwed with fix screw 4 in the screw.The center of back-up ring 3 inboard roll body 2 ends is provided with the bearing 7 that is supported on the center shaft 5.The outside of roll body 2 is provided with roller shell 1 with array configuration, and said array configuration is the array configuration that adopts into joint, damages to guarantee in a single day roller shell 1 that arbitrary single-unit takes place, can immediately roller shell 1 single-unit of corrupted be changed.Because such replacing is simple, the time of changing operation is short, and material consumption is few.Use carrying roller removably described in the utility model, can prolong to greatest extent service life of ground carrying roller, material is fully used, can solve effectively that localized wear takes place carrying roller and must integral body change the problem of a carrying roller.Learn that through experiment can reach the three-to-four-fold of present commercially available ground carrying roller the service life of carrying roller removably described in the utility model.The utility model adopts the detouchable sectional construction, comprises center shaft 5, back-up ring 3 and roll body 2, can make the best use of everything, and dismounting and easy for installation helps changing and safeguarding, can save human and material resources and financial resources in large quantities for the user.
