Abstract
The invention discloses a long-life, weld-free and low-noise backstop idler, comprising a bearing seat, a tightly fixed shaft, a backstop piece, a backstop seat, a backstop sleeve, a roller sheet, an idler shaft and a sealing element, wherein the bearing seat and the roller sheet are assembled in clearance fit, the bearing seat is connected with the backstop seat through the tightly fixed shaft, the backstop piece is connected to the tightly fixed shaft and arranged between the bearing seat and the backstop seat, the backstop sleeve is connected with the idler shaft through keys, and the sealing element is arranged in the bearing seat. The long-life, weld-free and low-noise backstop idler is reasonable in structure and convenient in installation and adjustment, can bear large backstop moment and can effectively prevent the downslide and overturning of an upward ribbon conveyer caused by interruption of power supply or fracture of an adhesive tape, so that the conveyer can operate safely and reliably.
Description
Technical field
The present invention relates to a kind of high life, exempt from welding, low noise Non-return idler, be mainly used in upper conveying belt type conveyer.
Background technology
Belt conveyer is mainly by carrying roller, and support, compositions such as transfer drive, carrying roller are one of main composition parts of belt conveyer, use the most extensive.Because belt speed and freight volume is different, the oad of carrying roller is different.Carrying roller kind commonly used has: impact idler, parallel roll, aligning carrier roller etc.
At present, the belt conveyer carrying roller mainly contains following kind both at home and abroad
1. parallel roll
Be used for the return leg support belt
2. impact idler:
Be installed in material feeding section below, reduce the suffered impact of load-transfer device
3. aligning carrier roller:
Be used to adjust belt deflection
But above-mentioned all kinds of carrying rollers itself all do not have braking function, and conveyer also needs to add in addition special brake equipment and carries out the braking of equipment.This will cause braking force to be concentrated, and can't realize the reliable parking of belt conveyer, reduce the safety of equipment.
Summary of the invention
The purpose of this invention is to provide a kind of high life, exempt from welding, low noise Non-return idler.
The objective of the invention is to realize through following technical scheme:
High life of the present invention, exempt from the welding, the low noise Non-return idler, comprise bearing seat, tightening axle, check sheet, check seat, check cover, roller skin, roller carrier shaft and sealing member.Bearing seat and roller skin interference fit, bearing seat is connected through the tightening axle with the check seat, and the check sheet is connected on the tightening axle, is located between bearing seat and the check seat, and the check cover is connected through key with roller carrier shaft, and sealing member is located in the bearing seat.
Technical scheme by the invention described above can be found out; High life of the present invention, exempt from welding, the low noise Non-return idler is rational in infrastructure; Installation, easy to adjust; The check moment of bearing is big, and downslide and reversing in the time of can preventing belt conveyer because of outage or adhesive tape fracture effectively make conveyer safe and reliable to operation.

The specific embodiment
High life of the present invention, exempt from the welding, the low noise Non-return idler; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7; High life, exempt from welding, low noise Non-return idler, comprise bearing seat 1, tightening axle 2, check sheet 3, check seat 4, check cover 5, roller skin 6, roller carrier shaft 7 and sealing member 8.
Bearing seat 1 and roller skin 6 interference fit, bearing seat 1 is connected through tightening axle 2 with check seat 4.
Check cover 5 and roller carrier shaft 7 are connected through key, and sealing member 8 is located in the bearing seat 1.
Bearing seat 1 adopts the design of U type annular seal space, and check cover 5 adopts swallowtail-shaped structure design, sealing member 8 employing labyrinths 6 loculus non-contact type structures.
For overcoming the deficiency of existing carrying roller and brake equipment, in conjunction with the requirement of multiple delivery system operating condition, the present invention designs a kind of high life, exempts from welding, low noise Non-return idler, can realize effective check.This device has improved the reliability of conveyer, has prolonged the service life of conveyer, has reduced the operation and maintenance expense of conveyer.The present invention has following inventive point:
High life, exempt from welding, low noise Non-return idler bearing seat adopts the design of U type annular seal space, forms airtight negative pressure space in the rotary course, has the effect of dustproof and waterproof;
High life, exempt from welding, low noise Non-return idler check cover adopts the swallowtail-shaped structure design, can the bilateral check, the impulsive force when reducing check can be stirred the check sheet when centnifugal force is not enough;
High life, exempt from welding, low noise Non-return idler check seat is provided with 4 check positions, check flexible movements, check cover chucking check sheet when guaranteeing the carrying roller check;
High life, exempt from welding, low noise Non-return idler check seat, bearing seat and roller skin and all adopt coaxial cooperation to press-fit, exempt from welding, thereby avoid the high temperature deformation influence, coaxial accuracy is high;
High life, exempt from welding, labyrinth 6 loculus non-contact type sealing members are adopted at low noise Non-return idler two ends, have the dustproof and waterproof function, damping coefficient is low, carrying roller rotates flexibly.
Below in conjunction with accompanying drawing to the high life, exempt to weld, the principle of work of low noise Non-return idler further specifies:
High life, exempt from welding, the low noise Non-return idler is installed on the upper conveying belt type conveyer support, when belt conveyer brought into operation, the carrying roller rotative speed was lower, check sheet 3 suffered centnifugal forces are less than its gravity, check cover 5 is stirred check sheet 3; When the rotating speed of carrying roller reached normal speed, check sheet 3 was attached on the inwall of roller skin 6 in 2 rotations of centrifugal action lower edge tightening axle, and this moment, check sheet 3 can not contact with check cover 5, and its mode of operation is as shown in Figure 6.
When the belt conveyer emergency braking; Carrying roller speed under the friction force effect of conveyor belt running drops to zero and the trend of reversing arranged, this moment since the centnifugal force of check sheet 3 less than its gravity, an end of check sheet 3 falls and check cover 5 comes in contact; Fall between check seat 4 and the check cover 5 " stuck "; Prevent the carrying roller reversing, thereby stoped the load-transfer device reversing, its mode of operation is as shown in Figure 7.
The invention has the beneficial effects as follows:
Rational in infrastructure, installation, easy to adjust, applicability is strong;
Noise is low during operation, and it is little to wear and tear;
Operating efficiency is high, and non-maintaining, operating cost is low.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
