[0002] In order to guarantee that the belt does not slacken for a long time use of the belt conveyor, generally installs the weight tensioning device under the belt conveyor, and the belt is pulled tight through the weight box, but because the weight tensioning device is arranged on the platform layer of the high elevation of the belt conveyor, the maintenance and replacement of the equipment and the safety performance are greatly discounted. SUMMARY

[0003] In order to solve the above problem, the utility model provides a vertical tensioning device for double air cushion belt conveyor, effectively improves safety performance, reduces maintenance difficulty.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: a vertical tensioning device for double air cushion belt conveyor, including guide rod, slide, change direction cylinder and weight box, the guide rod is arranged in pairs and is placed vertically, the slide is connected between the pair of guide rods and slides, the change direction cylinder is installed on the slide and is used for the change direction of the belt, the weight box is connected with the slide through the steel wire rope.

[0005] The guide rod is equipped with the climbing frame.

[0006] The buffer pad is arranged directly below the weight box.

[0007] The steel wire rope hook is arranged on the slide, and the weight box is hung on the slide through the steel wire rope.

[0008] The fence is arranged around the falling point of the weight box.

[0009] The utility model has the advantages that, compared with the prior art, the change direction cylinder is arranged on the slide and slides together with the slide, realizes the tensioning of the belt conveyor, the weight box is placed at the safe place on the ground through the traction of the steel wire rope, even if the belt conveyor is broken accidentally, the main force point of the weight box is on the ground, so that the serious safety accidents of equipment, steel structure and the like are not caused.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0015] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0016] like Figs. 1-2 As shown, this utility model provides a vertical tensioning device for a double air cushion belt conveyor, including a guide rod 1, a slide 2, a redirecting roller 3, and a counterweight box 4. The guide rods 1 are arranged in pairs and placed vertically. The slide 2 is slidably connected between the pair of guide rods 1. The redirecting roller 3 is installed on the slide 2 and is used to redirect the conveyor belt 5. The counterweight box 4 is connected to the slide 2 by a steel wire rope 6.

[0017] By setting the redirecting roller 3 on the carriage 2 and sliding it together with the carriage 2, the conveyor belt 5 is tensioned. The counterweight box 4 is placed on the ground safely by the traction of the wire rope 6. Even if the conveyor belt 5 breaks accidentally, the main point of force of the counterweight box 4 is on the ground, so it will not cause serious safety accidents to the equipment, steel structure, etc.

[0018] Specifically, the slide 2 is equipped with a wire rope hook 9, and the counterweight box 4 is hung on the slide 2 by a wire rope 6. The wire rope hook 9 facilitates the loading and unloading of the counterweight box 4.

[0019] Furthermore, to facilitate daily inspection and maintenance, a climbing frame 7 is provided on the guide rod 1.

[0020] Furthermore, in order to improve the safety performance of the system, a buffer pad 8 is provided directly below the weight box 4, and a fence 10 is provided around the landing point of the weight box 4.

[0021] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
