Abstract
The utility model discloses a tensioning structure on the tail portion of a bucket type elevator. The tensioning structure on the tail portion of the bucket type elevator comprises a rack and a tail portion bearing seat, wherein a sliding groove is formed in the rack, and the tail portion bearing seat is arranged inside the sliding groove in a sliding mode. A spring pre-tensioning device and a gravity tensioning device are arranged on the rack, wherein the spring pre-tensioning device is located above the tail portion bearing seat, and the gravity tensioning device is located below the tail portion bearing seat. The tensioning structure on the tail portion of the bucket type elevator is characterized in that a set of spring pre-tensioning devices are arranged above a tail portion bearing seat device, a set of gravity tensioning devices are arranged below the bearing seat, the bearing seat device can move up and down in the sliding groove, the gravity tensioning device is used for balancing in the process of a normal working condition, the spring pre-tensioning device can absorb redundant energy and exert a buffer effect in the process of an emergency, and therefore the situations of occurrence of tail portion moving upward and the like are effectively avoided, and device damage and accident expansion are avoided.
Description
Technical field
The utility model relates to a kind of gig, especially a kind of tension structure of bucket elevator afterbody.
Background technology
Bucket elevator is used very extensively industrial.Domestic and the external bucket elevator of producing is used gravity tensioning mostly at present, and the gravity tensioning amount is all bigger, for the operation of bucket elevator afterbody, is the equal of to have increased unnecessary resistance; And be subjected to the influence of operation conditions change, and adopt its assurance coefficient of mode of gravity tensioning also not high merely, in the real-world operation, situation such as scurry on the afterbody happens occasionally, and safe and highly efficient operation is brought hidden danger.
Therefore be necessary the tension structure of existing bucket elevator afterbody is improved.
Summary of the invention
The purpose of this utility model is the tension structure of the bucket elevator afterbody that a kind of buffering effect of designing for the deficiency that solves above-mentioned technology is better, assurance coefficient is higher.
The tension structure of the bucket elevator afterbody that the utility model is designed comprises frame and tail bearing seat, and described frame is provided with a chute, and described tail bearing seat is slidingly arranged in this chute; Described frame is provided with spring pre-tensioning device and gravity tensioning device, and described spring pre-tensioning device is positioned at the top of described tail bearing seat, and described gravity tensioning device is positioned at the below of tail bearing seat.
The tension structure of the bucket elevator afterbody that the utility model is designed, its concrete principle is: employing one sleeve spring pre-tensioning device on the tail bearing base device, below bearing seat, adopt a cover gravity tensioning device, bearing holder device can move up and down in chute, during nominal situation by the gravity tensioning balance, when accident occurring, the spring pre-tensioning device can absorb unnecessary energy and bring into play buffer action, effectively avoid the generation of situations such as scurrying on the afterbody, avoid device damage and accident to enlarge; This bucket elevator is through the test of how tame unit, and the result shows that this is a kind of effective structure, is specially adapted to large-scale hoister.
Description of drawings
Fig. 1 is the structural representation of the tension structure of embodiment 1 bucket elevator afterbody;
Fig. 2 is the lateral plan of the tension structure of embodiment 1 bucket elevator afterbody;
Among the figure: frame 1, tail bearing seat 2, chute 3, gravity tensioning device 4, spring pre-tensioning device 5.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, 2, the tension structure of the described bucket elevator afterbody of present embodiment comprises frame 1 and tail bearing seat 2, and described frame 1 is provided with a chute 3, and described tail bearing seat 2 is slidingly arranged in this chute 3; Described frame 1 is provided with spring pre-tensioning device 5 and gravity tensioning device 4, and described spring pre-tensioning device 5 is positioned at the top of described tail bearing seat 2, and described gravity tensioning device 4 is positioned at the below of tail bearing seat 2.
The tension structure of the described bucket elevator afterbody of present embodiment, its concrete principle is: employing one sleeve spring pre-tensioning device 5 on tail bearing seat 2 devices, below bearing seat, adopt a cover gravity tensioning device 4, bearing holder device can move up and down in chute 3, during nominal situation by the gravity tensioning balance, when accident occurring, spring pre-tensioning device 5 can absorb unnecessary energy and bring into play buffer action, effectively avoid the generation of situations such as scurrying on the afterbody, avoid device damage and accident to enlarge; This bucket elevator is through the test of how tame unit, and the result shows that this is a kind of effective structure, is specially adapted to large-scale hoister.
Need to prove in this area, described spring pre-tensioning device 5 and gravity tensioning device 4 all are conventional structure, and innovative point of the present utility model is them in conjunction with the technical matters with solution " adopting gravity tensioning device 4 can not effectively adapt to emergency case merely ".
Specific embodiment described herein only is that casehistory is made in design of the present utility model.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
