Description

Technical Field

[0001] The utility model relates to an anti - tearing rubber strip device with a protection function for the belt of a stacker - reclaimer during bidirectional operation, belonging to the technical field of stacker - reclaimer belt equipment. Background Technique

[0002] The stacker - reclaimer is a widely used large - scale loading device. In order to prevent the belt of the stacker - reclaimer from being torn, an anti - tearing rubber strip device is installed in the middle of the belt. The working principle of the anti - tearing rubber strip device is that when the belt is penetrated by sharp objects or impurities such as metal in the material and torn, the damaged part of the belt collides with the anti - tearing rubber strip device, impacting the anti - tearing rubber strip. Due to the pressure, the internal resistance value of the anti - tearing rubber strip changes, and then a belt - tearing alarm signal is output. After receiving the alarm signal, the operator takes countermeasures such as stopping the machine to avoid greater damage to the belt.

[0003] In the actual application process, since the bracket of the anti - tearing rubber strip device is laid flat under the belt, and the belt has a curvature due to the support of the idlers, the anti - tearing rubber strip device can only protect the part parallel to the idlers directly below the belt and cannot monitor and protect other parts of the belt. In addition, the anti - tearing rubber strip device must be installed against the running direction of the belt so as to ensure that the anti - tearing rubber strip is stressed when the belt is torn. During the operation of the stacker - reclaimer, the running directions of the belt in the stacking mode and the reclaiming mode are opposite. Therefore, the existing anti - tearing rubber strip device can only protect the belt when running against the belt, and has no protection effect when the belt moves in the reverse direction, so it is very necessary to be improved. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an anti - tearing rubber strip device for the belt of a stacker - reclaimer that can provide bidirectional protection. This anti - tearing rubber strip device can change its direction and always keep the anti - tearing rubber strip in the reverse running direction with the belt during the forward and reverse rotation of the belt in the stacking mode and the reclaiming mode operations of the stacker - reclaimer, so that the anti - tearing rubber strip can play a monitoring and alarming role and comprehensively protect the belt of the stacker - reclaimer.

[0005] The technical solution to solve the above - mentioned technical problem is as follows:

[0006] A belt anti - tear rubber strip device for a stacker - reclaimer that can provide two - way protection, which includes an anti - tear rubber strip fixing bracket, a bracket rotating plate, a bearing bracket, a rotating bearing, an electro - hydraulic push rod, and a pin shaft.

The two inclined rods on both sides of the U - shaped frame are parallel to the two side idlers of the belt idler respectively. The bracket rotating plate is an upright rectangular plate. The outer ends of the two inclined rods on both sides of the U - shaped frame of the anti - tear rubber strip fixing bracket are respectively vertically and fixedly connected to the upper parts of the two bracket rotating plates.

The plate surfaces of the two bracket rotating plates and the two bearing brackets are respectively parallel and opposite to each other. The upper parts of the two bracket rotating plates are respectively connected to the upper ends of the two bearing brackets through rotating bearings. The lower ends of the two bearing brackets are respectively welded and connected to the steel structures supporting both sides of the belt. The lower end of one bracket rotating plate is connected to the front end of the push rod of the electro - hydraulic push rod through a pin shaft. The base of the electro - hydraulic push rod is fixed on the steel structures supporting both sides of the belt.

The two rotating bearings are respectively embedded in the bearing installation holes of the two bearing brackets. The outer ring of the rotating bearing is welded to the bearing installation hole. A rotating shaft is installed in the inner ring of the rotating bearing. The rotating shaft and the inner ring of the rotating bearing are in a tight fit. One ends of the rotating shafts in the two rotating bearings are respectively vertically welded and connected to the upper parts of the plate surfaces of the two bracket rotating plates.

[0008] For the above - mentioned belt anti - tear rubber strip device for a stacker - reclaimer that can provide two - way protection, it also has limit bumpers and proximity switches. The two proximity switches are respectively located on both sides of a bearing bracket.

[0017] Figure 1 It shows that the anti-tearing rubber strip fixing bracket 2 is a U-shaped frame, which is located below the belt idler. The horizontal rod of the U-shaped frame is parallel to the middle idler of the belt, and the two inclined rods on both sides of the U-shaped frame are inclined outward respectively, and the two inclined rods on both sides of the U-shaped frame are parallel to the two side idlers of the belt respectively. Installing anti-tearing rubber strips on the horizontal rod and the inclined rods of the U-shaped frame of the anti-tearing rubber strip fixing bracket 2 can achieve the purpose of comprehensively protecting the belt.

When the bracket rotating plate 3 rotates, it can drive the anti-tearing rubber strip fixing bracket 2 to rotate together, so that the anti-tearing rubber strip installed on the anti-tearing rubber strip fixing bracket 2 changes its direction.

[0019] Figure 1 It shows that there are bearing brackets 4 on the inner sides of the two bracket rotating plates 3 respectively. The plate surfaces of the two bracket rotating plates 3 and the two bearing brackets 4 are parallel and opposite to each other respectively, and the lower ends of the two bearing brackets 4 are respectively welded and connected to the steel structure supports 1 on both sides of the belt.

Correspondingly, two limit iron blocks 8 are respectively welded on both sides of the bracket rotating plate 3 opposite to the proximity switches 9. The front ends of the two limit iron blocks 8 are respectively opposite to the contacts of the two proximity switches 9. When the anti-tearing rubber strip fixing bracket 2 tilts at a certain angle, the limit iron block 8 sweeps across the proximity switch 9, and the electro-hydraulic push rod 6 stops operating, achieving the purpose of controlling the tilting angle of the anti-tearing rubber strip.

[0023] Figure 2 It is shown that when the belt 10 runs counterclockwise, the push rod of the electro-hydraulic push rod 6 retracts backward, causing the bracket rotating plate 3 to rotate counterclockwise around the rotating bearing 5. The upper end of the bracket rotating plate 3 tilts towards the incoming material direction of the belt 10, driving the upper end of the anti-tearing rubber strip fixing bracket 2 connected to the bracket rotating plate 3 to also tilt towards the incoming material direction of the belt 10. The anti-tearing rubber strip of the anti-tearing rubber strip fixing bracket 2 is in a state of running against the belt 10, and the anti-tearing rubber strip can play a monitoring and alarm role.

[0024] Figure 3 It is shown that when the belt 10 runs clockwise, the push rod of the electro-hydraulic push rod 6 extends forward, causing the bracket rotating plate 3 to rotate clockwise around the rotating bearing. The upper end of the bracket rotating plate 3 tilts towards the forward running direction of the belt 10, driving the upper end of the anti-tearing rubber strip fixing bracket 2 connected to the bracket rotating plate 3 to tilt towards the forward running direction of the belt.
