Description

Technical Field

[0001] The invention discloses an anti-floating belt component for a belt conveyor, and belongs to the technical field of belt conveyors. Background Art

[0002] The conveyor belt in the belt conveyor will be set up as needed, with one section in a horizontal state and the other section in an inclined state. In this state, an anti-drifting roller needs to be installed between the horizontal and inclined parts of the conveyor belt. The bearing seats at both ends of the anti-drifting roller are connected to the two beams in the belt conveyor by means of bolts and nuts. For a longer conveyor belt, the conveyor belt exerts a greater force on the anti-drifting roller. At this time, the force received by the anti-drifting roller will act on the bolts connecting the bearing seat and the beam, causing the bolts to be subjected to a greater load. The bolts are more likely to be damaged due to being under high load for a long time, affecting the reliability of the overall structure. Summary of the invention

[0009] Specifically, a reinforcing beam is provided directly below the supporting roller, and two ends of the reinforcing beam are respectively connected and fixed to the legs of the two cross beams close to the supporting roller.

[0010] Specifically, a detachable inclined beam is installed at one end of the two cross beams away from the supporting roller, and the inclined beam is arranged to be inclined upward. A plurality of brackets are installed equidistantly between the two inclined beams, and three circular rollers for supporting the conveyor belts are rotatably installed in the brackets.

[0012] Beneficial effects of the present invention:

[0013] 1. Adjust the distance between the support roller and the reversing roller. At this time, the support roller drives the moving seat to move along the T-bar. At this time, the relative position of the adjusting screw and the support plate changes, so as to adjust the tension of the conveyor belt. After the position of the support roller is adjusted, the two fourth nuts are used to limit the relative position of the adjusting screw and the support plate.

[0014] 2. Adjust the position of the vertical screw along the vertical hole. At this time, the distance between the legs and the feet changes. When the beam is in a horizontal state, use the two fifth nuts to limit the relative position of the vertical screw and the base plate to adjust the horizontal state of the beam as needed, so that the beam can be placed in a horizontal state on an uneven ground.

[0015] 3. Make the conveyor belt pass around the anti-floating roller, reversing roller, supporting roller and holding roller in sequence, so that the anti-floating roller is between the horizontal section and the inclined section of the conveyor belt. Under the restriction of the anti-floating roller, the conveyor belt is prevented from floating. The fine roller, round roller and supporting roller also play a role in restricting the conveyor belt.

[0016] 4. Two studs are threadedly connected in a straight thread barrel, so that multiple studs and multiple straight thread barrels form a pull rod structure with adjustable length. There is no need to produce longer studs, and it is convenient to adjust the length of the pull rod structure according to the density of the blocking block, that is, adjust the length of the stud in the straight thread barrel, so that the length of the pull rod structure formed by multiple studs and multiple straight thread barrels can be shortened or lengthened.

[0017] 5. Studs are inserted into the two through holes on the pressure plate, and then the two first nuts are used to limit the relative positions of the pressure plate and the studs. After multiple straight threaded barrels are alternately connected to multiple studs, the pressure plate is in contact with the blocking block, and the two studs closest to the vertical plate are connected to the vertical plate. At this time, the force of the conveyor belt acting on the anti-drifting roller is dispersed to multiple parts of the cross beam and the bottom beam through the studs, pressure plate, straight threaded barrel, and blocking block, preventing the first bolt from being under high load for a long time, thereby improving the stability and reliability of the structure.

The second nut 26 is threadedly connected to the stud 25, and the two studs 25 are threadedly connected in a straight thread tube 6, so that Multiple studs 25 and multiple straight threaded tubes 6 form a pull rod structure with adjustable length. There is no need to produce longer studs 25, and it is convenient to adjust the length of the pull rod structure according to the density of the blocking block 23, that is, adjust the length of the stud 25 in the straight threaded tube 6, so that the length of the pull rod structure formed by the multiple studs 25 and the multiple straight threaded tubes 6 becomes shorter and longer. Studs 25 are inserted into the two through holes 35 on the pressure plate 24, and then the two first nuts 19 are used to limit the relative position of the pressure plate 24 and the studs 25.
