Abstract
The utility model discloses a spring buffering carrier roller set, including bearing roller group and spring buffer, the lower part bilateral symmetry of bearing roller group sets up spring buffer, spring buffer comprises bolt post, nut, crossbeam and spring, bolt post one end fixed mounting organizes the lower part at the bearing roller, and other end cover shock mount passes the crossbeam and fixes through the nut fastening simultaneously. This device installation easy maintenance has effectively improved the shock resistance of bearing roller group, and reducing impact power improves life and security to the loss of each part to the belt conveyor traveling comfort has been improved to a certain extent.
Description
Technical field
The utility model relates to belt conveyer buffer technology field, especially relates to a kind of spring buffer supporting roller group.
Background technology
The material that belt conveyer transports is varied, and more the lump coal of some material if coal is many bulks forms, and the instant impact of these materials is very large, is easy to damage the consumption-type such as belt, carrying roller parts under such impact effect.Now, the development tendency of belt conveyer is large conveying quantity and high belt speed, and these make to impact and strengthen further the impact of conveyer.In such large impact variable load environment, common rubber buffer carrying roller is limited for the buffering effect of these application forces.Common impact idler absorbs impulsive force by the rubber ring on carrying roller surface, and because the deformability of rubber ring can not show a candle to spring, in deflection of spring, the size of application force and in-service time are inversely proportional to, so rubber ring is closer to rigid shock.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is the buffer action effect providing a kind of lifting to impulsive force, improves the running stability of conveyer, reduces impulsive force to the spring buffer supporting roller group of the loss of each parts.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is spring buffer supporting roller group, comprises idler machining and spring bumper; Described idler machining bottom is symmetrical set spring bumper, and the middle idler machining institute of described idler machining is to being symmetrical set spring bumper under roller rack; Described spring bumper is made up of bolt column, nut, crossbeam and spring; Described bolt column one end is fixedly mounted on idler machining bottom, and other end pocketed springs is also fixed by fastening nuts through crossbeam simultaneously.This device is effectively used in belt conveyer charging process and reduces material to belt and strut member impact occasion, effectively change existing buffer action mode, promote the buffer action effect to impulsive force, improve the running stability of conveyer, and reduce the loss of impulsive force to each parts, improve service life and safety.
As optimization, the bolt column between described nut and crossbeam arranges sliding sleeve, sliding sleeve is placed on the downside of crossbeam, in order to reduce the center of gravity of parts, improves stability; The fit system of sliding sleeve and bolt column selects small―gap suture to coordinate, and adopts grease lubrication, plays the effect of the antirust and isolated pollutants of actv., the service life of extension device.
As preferably, described idler machining is common idler machining or impact idler group.
As preferably, the quantity that described nut is arranged is 2, uses double nuts self-locking, prevents equipment from loosening, and ensures the durable for a long time of equipment.
Compared with prior art, the beneficial effects of the utility model are: the installation and maintenance of this device are convenient, effectively improve the impact resistance of idler machining, reduce impulsive force to the loss of each parts, improve service life and safety, and improve belt conveyer traveling comfort to a certain extent.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is main structure schematic diagram of the present utility model;
Fig. 2 is that A in Fig. 1 is to structural representation.
Mark in figure: idler machining 1, bolt column 2, nut 3, crossbeam 4 and sliding sleeve 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in Figures 1 and 2, the utility model is a kind of spring buffer supporting roller group, comprises idler machining 1 and spring bumper; Described idler machining 1 bottom is symmetrical set spring bumper; The middle idler machining institute of described idler machining 1 is to being symmetrical set spring bumper under roller rack; Described spring bumper is made up of bolt column 2, nut 3, crossbeam 4 and spring; Described bolt column 2 one end is fixedly mounted on idler machining 1 bottom, and other end pocketed springs is also fastened and fixed by nut 3 through crossbeam 4 simultaneously.
What absorb impulsive force is be sleeved on the Compress Spring on bolt column 2, and spring is between idler machining 1 middle idler roller support and crossbeam 4, and bolt column 2 is for the sense of displacement of restraining spring, and bolt column 2 is fastened and fixed the stroke for limiting idler machining 1 by nut 3; Use the fixing also easy disassembly and maintenance of nut 3.First impulsive force acts on idler machining 1, idler machining 1 will move down under force, elastic deformation is there is in the spring being in compressive state under the effect of impulsive force, energy is absorbed in the process of deformation, and slow releasing, soft landing when material is fallen from eminence, reaches the object of cushion impact forces.The compressive state of spring is by pre-load nut 3 realization in advance, the another one effect of nut 3 is after impulsive force forces spring-compressed to ultimate limit state, spring will rebound, and now nut 3 can play spacing effect, makes idler machining 1 be in state safely and effectively all the time.Because the absorption stroke of spring is longer, spring can be changed according to actual impulse again, ensure its impact resistance and comformability.Idler machining 1 meeting is subjected to displacement in the axis of bolt column 2, ensure that the stability of structure.This device is effectively used in belt conveyer charging process and reduces material to belt and strut member impact occasion, effectively change existing buffer action mode, promote the buffer action effect to impulsive force, improve the running stability of conveyer, and reduce the loss of impulsive force to each parts, improve service life and safety.
Embodiment 2, to being optimized design on the basis of embodiment 1, the bolt column 2 between described nut 3 and crossbeam 4 arranges sliding sleeve 5.Sliding sleeve 5 is placed on the downside of crossbeam 4, in order to reduce the center of gravity of parts, improves stability; The fit system of sliding sleeve 5 and bolt column 2 selects small―gap suture to coordinate, and adopts grease lubrication, plays the effect of the antirust and isolated pollutants of actv., the service life of extension device.
Embodiment 3, decision design is carried out to idler machining 1 in the basis of embodiment 1, and described idler machining 1 is common idler machining or impact idler group.
Embodiment 4, decision design is carried out to the quantity of nut 3 in the basis of embodiment 1, and the quantity that described nut 3 is arranged is 2, uses double nuts self-locking, prevents equipment from loosening, and ensures the durable for a long time of equipment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
