Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a belt deviation-correcting device and a conveyor. Background Art

[0002] Belt conveyors are a common type of equipment used today. They offer advantages such as high speed, high capacity, and excellent transport continuity, making them widely used across various industries. They are particularly important in the metallurgical and mining industries, where they play an irreplaceable role. However, because belt conveyors typically transport goods over long distances and are flexible, belt deviation is a common problem in practice.

[0003] Considering that belt deviation is the most common fault in existing belt conveyor systems, belt conveyor designs typically incorporate an adjustment device at the end of the belt to correct for deviation. This adjustment is achieved by adding or removing counterweights. However, this adjustment method becomes less effective as the belt becomes longer, leading to material spillage and accelerated belt wear. Utility Model Content

[0004] In order to overcome the problem that the existing belt deviation correcting device has poor effect when applied to a long belt, the utility model provides a belt deviation correcting device and a conveyor.

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

[0006] The belt correcting device includes a support, a roller assembly, a supporting rod, a first pull rod, a second pull rod and a bidirectional nut. The support, roller assembly and support rod are each provided in two groups. The roller assembly includes a roller shaft and a roller. The roller is rotatably connected to the roller shaft. One end of the roller shaft is hinged to the support. The axis of the hinge shaft of the roller shaft and the support is perpendicular to the axis of the roller shaft, and the other end is fixedly connected to the support rod; the first pull rod and the second pull rod are respectively threadedly connected to both sides of the bidirectional nut, and the first pull rod and the second pull rod each correspond to a group of supports, roller assembly and support rod. One end of the support rod is fixedly connected to the roller shaft, and the other end is fixedly connected to the corresponding first pull rod or second pull rod; the axis of the hinge shaft of the roller shaft and the support is perpendicular to the center line of the bidirectional nut. The movement of the bidirectional nut can shorten or lengthen the distance between the first pull rod and the second pull rod.

[0007] In the present application, two sets of roller assemblies are set up. During use, the two sets of roller assemblies are used on both sides of the belt running direction to abut and limit the belt, thereby limiting the belt from deviation; and through the setting of a two-way nut, a first pull rod and a second pull rod, the distance between the two sets of roller assemblies can be adjusted, and the distance can be adjusted according to the on-site conditions, thereby achieving a better limiting effect.

[0008] In some embodiments, a locking nut is provided at the connection between the bidirectional nut and the first pull rod, and at the connection between the bidirectional nut and the second pull rod.

[0009] In this embodiment, a locking nut is additionally provided to make the connection between the bidirectional nut and the first pull rod and the second pull rod more stable.

[0010] In some embodiments, a toggle portion is provided in the middle of the bidirectional nut.

[0011] In this embodiment, a toggle portion is provided in the middle of the bidirectional nut, and common methods include providing a protrusion for toggle, providing texture to increase friction, etc., to facilitate the rotation of the bidirectional nut.

[0012] In some embodiments, the roller assembly and the support are hinged via a pin.

[0013] In this embodiment, a pin connects the roller assembly and the support, which is convenient for implementation.

[0014] In some embodiments, the roller and the roller shaft are connected via a bearing.

[0015] In this embodiment, the bearing connects the roller and the roller shaft, which is easy to implement and has a relatively small rotational resistance, thereby reducing the wear on the belt during operation when the roller and the belt abut against each other.

[0016] The utility model also provides a conveyor, comprising a belt and the belt correcting device described in any of the above embodiments, wherein the support in the belt correcting device is fixedly connected to the belt bracket, and the two roller assemblies in the belt correcting device are arranged on both sides of the belt running direction, and the axis direction of the articulated shaft between the roller shaft and the support is consistent with the belt running direction.

[0017] In the conveyor, the support is fixedly connected to the belt brackets on both sides of the belt, and the running directions of the belts are consistent in the axis direction of the hinge shaft, so that the two-way nut is adjusted to adjust the relative position between the roller assembly and the belt when the distance between the first pull rod and the second pull rod is shortened or lengthened.

[0018] In some embodiments, a belt deviation correcting device is provided every 8m-12m in the running direction of the belt.

[0019] In this embodiment, the above interval setting is preferably used to limit the belt at multiple points, thereby achieving a better deviation correction effect.

[0020] The beneficial effects of the utility model are:

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-2 As shown, the utility model provides a belt deviation correcting device.

[0030] The belt correcting device includes a support 1, a roller assembly 2, a supporting rod, a first pull rod 4, a second pull rod 7 and a bidirectional nut 5. The support 1, the roller assembly 2 and the support rod 8 are each provided in two groups. The roller assembly 2 includes a roller shaft 3 and a roller 21. The roller 21 is rotatably connected to the roller shaft 3. One end of the roller shaft 3 is hinged to the support 1. The axis of the hinge axis of the roller shaft 3 and the support 1 is perpendicular to the axis of the roller shaft 3, and the other end is fixedly connected to the support rod 8; the first pull rod 4 and the second pull rod 7 are respectively threadedly connected to both sides of the bidirectional nut 5, and the first pull rod 4 and the second pull rod 7 each correspond to a group of support 1, the roller assembly 2 and the support rod 8. One end of the support rod 8 is fixedly connected to the roller shaft 3, and the other end is fixedly connected to the corresponding first pull rod 4 or the second pull rod 7; the axis of the hinge axis of the roller shaft 3 and the support 1 is perpendicular to the center line of the bidirectional nut 5. When the bidirectional nut 5 is moved, the distance between the first pull rod 4 and the second pull rod 7 can be shortened or lengthened.

[0031] In the present application, two sets of roller assemblies 2 are provided. During use, the two sets of roller assemblies 2 are used on both sides of the belt running direction to abut and limit the belt, thereby limiting the belt from deviation; and through the provision of a bidirectional nut 5, a first pull rod 4 and a second pull rod 7, the distance between the two sets of roller assemblies 2 can be adjusted, and the distance can be adjusted according to the on-site conditions, thereby achieving a better limiting effect.

[0032] Obviously, the threads of the first pull rod 4 and the second pull rod 7 are respectively adapted to the thread directions at both ends of the bidirectional nut 5, so that when the bidirectional nut 5 rotates, the first pull rod 4 and the second pull rod 7 move closer to or farther away from each other, thereby driving the roller assembly 2 to rotate around the hinge axis and adjusting the distance between the two roller assemblies 2.

[0033] Preferably, when the two-way nut 5 is installed, an adjustment gap of about 10 mm is left. In practice, the first pull rod 4 and the second pull rod 7 are first installed, and after adjusting the gap, the first pull rod 4 and the second pull rod 7 are welded to the support rod 8.

[0034] In practice, the adjustment purpose can be achieved when the adjustable distance between the first pull rod 4 and the second pull rod 7 is less than 4 cm. In this embodiment, the first pull rod 4 and the support rod 8 are welded, and the second pull rod 7 and the support rod 8 are welded. The first pull rod 4, the second pull rod 7 and / or the support rod 8 can be deformed to achieve the first pull rod 4 and the second pull rod 7 to be screwed in and out relative to the two-way nut 5, that is, the distance between the first pull rod 4 and the second pull rod 7 is shortened or extended, that is, the movable ends of the two rollers 21 are brought closer or farther away.

[0035] In this embodiment, locking nuts 6 are provided at the connection between the bidirectional nut 5 and the first pull rod 4, and at the connection between the bidirectional nut 5 and the second pull rod 7. The locking nuts 6 are added to make the connection between the bidirectional nut 5 and the first pull rod 4 and the second pull rod 7 more stable.

[0036] In some embodiments, a toggle portion is provided in the middle of the bidirectional nut 5 . Common methods include providing a protrusion for toggling, providing texture to increase friction, etc., to facilitate the rotation of the bidirectional nut 5 .

[0037] In this embodiment, the roller assembly 2 and the support 1 are hinged via a pin 23 , and the pin 23 connects the roller assembly 2 and the support 1 , which facilitates implementation.

[0038] In this embodiment, the roller 21 and the roller shaft 3 are connected by a bearing 24, which is convenient for implementation and has a relatively small rotation resistance, thereby reducing the wear of the belt during operation when the roller 21 and the belt abut against each other. Figure 2 As shown, bearing end covers 22 are provided at both ends of the roller 21 .

[0039] The bearing 24 of the belt deviation correcting device is periodically filled with grease during use to keep the bearing 24 well lubricated, thereby ensuring the normal rotation of the roller 21 without wearing the belt edge.

[0040] When the belt correcting device is applied to the conveyor belt, the support 1 in the belt correcting device is fixedly connected to the belt bracket, and the two roller assemblies 2 in the belt correcting device are arranged on both sides of the belt running direction, and the axis direction of the roller shaft 3 and the hinge shaft of the support 1 is consistent with the belt running direction.

[0041] In the conveyor, the support 1 is fixedly connected to the belt brackets on both sides of the belt, and the running directions of the belts are consistent in the direction of the axis of the hinge shaft, so that the two-way nut 5 is adjusted to adjust the relative position between the roller assembly 2 and the belt when the distance between the first pull rod 4 and the second pull rod 7 is shortened or lengthened.

[0042] Furthermore, in the running direction of the belt, a set of belt correction devices is preferably set every 8m-12m to limit the belt at multiple points, thereby achieving a better correction effect.

[0043] In practice, when a belt deviates, it is often necessary to adjust multiple sets of belt correcting devices, and the adjustment distance is determined according to the belt deflection position.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
