Abstract
The utility model discloses a broken belt catcher lever interlocking mechanism for a belt conveyor, which comprises a lever, an upper catching frame and a lower catching frame, wherein the lever is hinged on a frame through a hinge point; a first sliding groove and a second sliding groove are respectively arranged at two ends of the lever; a first pin shaft is fixed on the upper capturing frame; and a second pin shaft is fixed on the lower catching frame. The utility model discloses an on grab and catch frame upset and drive the lever and use the hinge point to rotate clockwise as the center, when on grab and catch frame rotation to certain angle, on grab and catch frame and lever and break away from, implement the upper belt and grab, grab down and catch frame and lever and break away from, implement down the belt and grab, realize the upper belt and implement and grab the back of catching, lower belt just can implement and grab, can effectively avoid when the conveyer lifts up or loads and lead to lower belt when lax to implement and grab lower belt.
Description
Technical Field
The utility model relates to a lever interlocking gear especially relates to a broken belt is caught ware lever interlocking gear for belt conveyor.
Background
The belt conveyor is an important device for mine bulk material conveying, and is developed in the direction of high power, high belt speed and large conveying capacity. The conveyer belt, especially the conveyer belt joint, is easy to have belt breakage accidents due to long-term work under high load and severe environment. Once the belt is broken, the belt can cause great damage to equipment and even cause casualties. Therefore, the problem of broken belt catching is deeply researched, the fast sliding conveying belt can be reliably and rapidly braked after the belt is broken, the loss caused by the broken belt accident is reduced to the minimum, and the method is particularly important in the safety production of the current mine.
The broken belt catcher is a broken belt protection device, can catch broken conveying belts, and can effectively avoid further extension of broken belt accidents. When the broken belt catcher has the belt breakage phenomenon, the upper catching frame and the lower catching frame respectively catch the upper broken belt surface and the lower broken belt surface at the same time. However, when the conveyor is lifted and loaded, the lower capturing frame is easy to generate misoperation on the loose lower belt, which seriously affects the production efficiency and reduces the reliability of the broken belt capturing device.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a weak point of avoiding above-mentioned prior art to exist provides a broken belt catcher lever interlocking gear for belt conveyor. When the belt is disconnected, the lower belt can be caught only after the upper belt is caught, so that the lower belt can be effectively prevented from being caught by mistake when the lower belt is loosened due to lifting or loading of the conveyor.
The utility model discloses the technical scheme who adopts does: a broken belt catcher lever interlocking mechanism for a belt conveyor comprises a lever, an upper catching frame and a lower catching frame; the lever is hinged on the rack through a hinge point; a first sliding groove and a second sliding groove are respectively arranged at two ends of the lever; a first pin shaft is fixed on the upper capturing frame; and a second pin shaft is fixed on the lower catching frame.
The first pin shaft is sleeved in the first sliding groove.
The second pin shaft is sleeved in the second sliding groove.
The hinge point rotates in the frame through the rotating shaft.
And a bearing is sleeved on the inner side of the rotating shaft.
And a bearing seat is fixed on the outer side of the bearing and is fixed with the frame.
Owing to adopted above-mentioned technical scheme, the utility model discloses profitable effect has been gained.
1. When the lower belt is loosened, the false action of capturing the lower belt can be effectively avoided;
2. the utility model discloses a lever mechanism has been adopted, simple structure can not exert an influence to the action of arresting of epitheca area.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the hinge point structure.
Wherein the content of the first and second substances,
1. the device comprises a lever 2, an upper capturing frame 3, a lower capturing frame 4, a hinge point 5, a rack 6, a first sliding chute 7, a second sliding chute 8, a first pin shaft 9, a second pin shaft 10, a rotating shaft 11, a bearing 12, a bearing seat 13 and a weight box.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, but the present invention is not limited to these embodiments.
As shown in fig. 1, a broken belt catcher lever interlocking mechanism for a belt conveyor comprises a lever 1, an upper catching frame 2 and a lower catching frame 3; the lever 1 is hinged on the frame 5 through a hinge point 4; a first sliding groove 6 and a second sliding groove 7 are respectively arranged at two ends of the lever 1; a first pin shaft 8 is fixed on the upper capturing frame 2; and a second pin shaft 9 is fixed on the lower catching frame.
The first pin shaft 8 is embedded in the first chute 6 in a sleeved mode.
The second pin shaft 9 is embedded in the second chute 7.
The hinge point 4 rotates in the frame 5 through a rotating shaft 10.
And a bearing 11 is sleeved on the inner side of the rotating shaft 10.
And a bearing seat 12 is fixed on the outer side of the bearing 11 and is fixed with the frame 5.
The working principle of the utility model can be briefly described as follows: after a conveyor belt is disconnected, the upper capturing frame 2 rotates anticlockwise under the driving of gravity of the weight box 13, meanwhile, the lever 1 is driven to rotate clockwise by taking the hinge point 4 as a center, the first pin shaft 8 and the second pin shaft 9 move in the first sliding groove 6 and the second sliding groove 7 respectively, when the upper capturing frame 2 rotates to a certain angle, the upper capturing frame 2 is separated from the lever 1, the upper capturing frame 2 continues to capture an upper belt under the driving of gravity of the weight box 13, the lower capturing frame 3 is also separated from the lever 1, and the lower capturing frame 3 continues to rotate clockwise under the driving of self gravity to capture a lower belt.
The parts not mentioned in the utility model can be realized by adopting or using the prior art for reference.
In the description of the present invention, it is to be understood that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
