Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a traction roller for belt conveyors. Background Art

[0002] Conveyor belt deviation is a common fault in the operation of belt conveyors. It is mainly manifested in that the conveyor belt continues to deviate to one side during movement, and may rub, wear or even get stuck with the frame. The reasons for conveyor belt deviation include uneven conveyor belt joints, roller installation errors, roller damage, uneven material distribution, etc.

[0003] At present, the deviation problem caused by the uneven joint of the conveyor belt is mainly solved by adjusting the position of the two sides of the driving wheel or the driven wheel to balance the tension of the conveyor belt; as for the problems of roller installation error, roller damage and material distribution, they need to be overcome by regularly checking the installation status and wear of the rollers and rollers; in actual applications, once the traditional belt conveyor deviates during operation, it is often difficult to correct it immediately; especially in an emergency, if the conveyor belt cannot be stopped immediately, it may continue to deviate from the track, aggravate wear and even cause safety accidents; therefore, in order to solve this problem, the present application provides a traction roller for a belt conveyor. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a traction roller for a belt conveyor, which can pull the conveyor belt when the conveyor belt cannot be stopped immediately to correct the deviation of the conveyor belt.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A traction roller for a belt conveyor is provided, comprising a traction roller body and a conical sleeve, wherein the conical sleeve is arranged on one side of the traction roller body, the conical sleeve abuts against the inner edge of the conveyor belt, and connecting ends are respectively arranged at both ends of the traction roller body, the connecting ends are rotatably connected to a fixed frame through two connecting rods of the same length, and the fixed frame is detachably mounted on the inner wall of the frame of the conveyor.

[0007] Furthermore, the connecting end, the fixing frame and the two connecting rods form a parallelogram mechanism.

[0008] Furthermore, a telescopic driver is rotatably mounted on the fixed frame, a movable end of the telescopic driver is rotatably connected to a hinge seat, and the hinge seat is fixedly mounted on a connecting rod located at the edge.

[0009] Furthermore, the conical sleeve is detachably fixedly mounted on one side of the traction roller body.

[0010] Furthermore, the conical sleeve is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The traction roller for belt conveyor in the utility model example has a parallelogram structure composed of the connecting end, the fixing frame and the two connecting rods. By starting the telescopic drive to drive the individual connecting rods to rotate, the traction roller body can be smoothly swung and controlled. The conical sleeve at the end of the traction roller body is used to push the conveyor belt toward the middle of the conveyor, so that in an emergency situation where the conveyor belt cannot be stopped immediately, the deviated conveyor belt can be corrected.

[0013] 2. The traction roller for the belt conveyor in the example of the utility model moves in the horizontal direction and in the vertical direction at the same time under the guidance of multiple connecting rods on both sides, so that a vertical upward thrust can be applied to the objects carried by the conveyor belt. By controlling the reciprocating rotation of the connecting rod, the traction roller body can impact the conveyor belt multiple times, and the material carried by the conveyor belt can be vibrated, so that the material concentrated on one side of the conveyor belt can be evenly distributed, thereby overcoming the problem of conveyor belt deviation caused by uneven material distribution.

[0014] 3. In the belt conveyor traction roller of the utility model example, the conical sleeve is detachably fixedly mounted on one side of the traction roller body, and can be adapted to different types of belt conveyors by replacing conical sleeves of different specifications.

[0027] Embodiment 1:

[0028] like Figure 1-3 As shown, this embodiment provides a traction roller for a belt conveyor, including a traction roller body 11 and a conical sleeve 13 made of stainless steel. The conical sleeve 13 is detachably fixedly installed on one side of the traction roller body 11. By replacing the conical sleeve 13 of different specifications, it can adapt to different types of belt conveyors.

[0029] The conical sleeve 13 abuts against the inner edge of the conveyor belt 1, and the two ends of the traction roller body 11 are respectively provided with connecting ends 12, which are rotatably connected to the fixed frame 21 through two connecting rods 22 of the same length. The fixed frame 21 is detachably mounted on the inner wall of the frame of the conveyor.

[0030] The connecting end 12 , the fixing frame 21 and the two connecting rods 22 form a parallelogram mechanism.

[0031] Among them, the traction roller body 11 is composed of a roller shaft, a bearing seat and a traction cylinder. The roller shaft passes through the bearing seat and the traction cylinder. A bearing and a sealing ring are arranged on the bearing seat. The inner side surfaces of the bearing and the sealing ring are in contact with the outer side wall of the roller shaft. The connecting end 12 is arranged at the end of the roller shaft, and the conical sleeve 13 is installed at the outer end of the traction cylinder.

[0032] A telescopic driver 24 is rotatably mounted on the fixed frame 21 , and a movable end of the telescopic driver 24 is rotatably connected to a hinge seat 23 , and the hinge seat 23 is fixedly mounted on a connecting rod 22 located at the edge.

[0033] The telescopic drive 24 can use an electric telescopic rod or a hydraulic rod that can be purchased on the market.

[0034] When the conveyor belt needs to be corrected and pulled, the telescopic drive 24 is started to drive the separate connecting rod 22 to rotate, so that the traction roller body 11 can swing smoothly, and the conical sleeve 13 at the end of the traction roller body 11 is used to push the conveyor belt 1 toward the middle of the conveyor, so that in an emergency situation where the conveyor belt cannot be stopped immediately, the deviated conveyor belt 1 can be corrected.

[0035] Under the guidance of multiple connecting rods 22 on both sides, the traction roller body 11 moves in the horizontal direction and the vertical direction at the same time, so that it can exert a vertical upward thrust on the object carried by the conveyor belt 1. By controlling the reciprocating rotation of the connecting rod 22, the traction roller body 11 can impact the conveyor belt 1 multiple times, and the material carried by the conveyor belt 1 is vibrated, so that the material concentrated on one side of the conveyor belt 1 can be evenly distributed, thereby overcoming the problem of conveyor belt deviation caused by uneven material distribution.

[0036] Embodiment 2:

[0037] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4 As shown, in this embodiment, two traction roller bodies 11 are provided, and the two traction roller bodies 11 are oppositely installed on the inner side of the conveyor belt 1. The two traction roller bodies 11 are used in pairs to correct the conveyor belt that deviates to both sides.

[0038] In addition, a plurality of pairs of traction roller bodies 11 may be provided. By increasing the number of traction roller bodies 11, the efficiency of correcting the deviated conveyor belt is improved.

[0039] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
