Description

Technical Field

[0001] The utility model relates to the technical field of anti-floating belts, in particular to an anti-floating belt device for a coal conveyor belt. Background Art

[0002] Coal mined by underground tunneling equipment is typically transported to a designated location via belt conveyors and then brought to the surface via mine cars. Because the coal conveyor belts typically operate at high speeds, they are prone to ripples when discharging coal head-on, especially when traversing ramps. This causes the belts to buckle and undulate, accelerating wear. Furthermore, ripples can easily cause coal spillage, requiring underground workers to constantly clean them up, a time-consuming and labor-intensive process that hinders standardized, mechanized underground construction practices. Therefore, improvements to existing technologies are necessary.

[0003] Chinese patent publication number CN220350807U discloses a belt conveyor anti-stripping device, comprising a crossbeam; columns are symmetrically mounted at both ends of the crossbeam, and a base with a grooved cross-section is mounted at the bottom end of each column; two pulley assemblies are mounted on the crossbeam, each pulley assembly comprising a first sleeve, a second sleeve, a connecting rod, and a roller; the first sleeve is slidably mounted on the crossbeam; the second sleeve is fixedly connected to the first sleeve, and the axial direction of the second sleeve is perpendicular to the axial direction of the first sleeve; the connecting rod is slidably inserted into the second sleeve; a rotating shaft is vertically provided on the bottom side wall of the connecting rod; and the roller is rotatably mounted on the rotating shaft via a bearing. The roller contacts the coal conveyor belt, effectively preventing the occurrence of streamers, thereby avoiding coal spillage and further improving coal mine production efficiency.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: the above-mentioned solution limits the conveyor belt by pressing the wheel to prevent the belt from floating. In actual use, the pressing wheel will reduce the available area of the conveyor belt, thereby reducing the efficiency of the conveyor belt. Utility Model Content

[0034] The docking component 3 includes an arc-shaped groove 302 provided on the mounting bracket 1 , the inner wall of the arc-shaped groove 302 is slidably connected to a locking member 303 , the locking member 303 is threadedly connected to the docking member 301 , and arc-shaped depressions are provided on both sides of the docking member 301 .

[0035] The conveying component 4 includes a conveyor belt 401 rotatably connected to the mounting bracket 1, the conveyor belt 401 is transmission-connected to a driving pulley 402, the mounting bracket 1 is connected to a rotating motor 403, and the output end of the rotating motor 403 is connected to the driving pulley 402. The side of the mounting bracket 1 is connected to two limit plates, and the two limit plates are symmetrically arranged on the top and bottom sides of the conveyor belt 401. The side of the mounting bracket 1 is rotationally connected to a driven pulley 404, and the driven pulley 404 is transmission-connected to the conveyor belt 401.

[0036] The side of the mounting bracket 1 is rotatably connected to a guide roller 406, and the guide roller 406 is transmission-connected to the conveyor belt 401.

A contact member 504 is connected to the top of the lifting plate 501, and the other end of the contact member 504 contacts the outer side of the conveyor belt 401. The guide rollers 406 are symmetrically arranged on both sides of the top of the lifting plate 501, and the part of the conveyor belt 401 located above the lifting plate 501 is in a horizontal state.
