Description

Technical Field

[0001] This utility model relates to the field of tubular belt conveyor technology, and specifically to an automatic correction device for tubular belt conveyors. Background Technology

[0002] Tubular belt conveyors are widely used in material handling processes in metallurgy and mining due to their ability to achieve continuous, efficient, and stable material handling. However, during operation, the conveyor belt may deviate at the beginning and end of the conveyor or twist in the middle section. If not corrected in time, this can lead to serious consequences such as belt stacking or tearing, resulting in production stoppage.

[0003] Currently, manual correction using hand-operated hoists is often used to address belt conveyor deviation. This method is inefficient and requires stopping the machine for correction. When dealing with belt conveyors that can stretch for several kilometers, the correction process is time-consuming and significantly impacts the company's production efficiency.

[0004] At the belt forming section of a conveyor belt system, two or three positioning guide rollers are typically used to hold the belt in place to ensure a reliable overlap. If the overlap changes or misaligns during belt operation, the belt will run off-track when it reaches the unfolding section, causing numerous adverse effects.

[0005] Chinese patent CN219858936U discloses a belt correction device for a circular tube belt conveyor, comprising a base, a belt, a rotating support assembly, and a second drive assembly. However, this device is too large to be suitable for bidirectional circular tube belt conveyors. Furthermore, it uses bottom idlers for correction, resulting in a single correction angle and low correction energy, making it unsuitable for correcting the belts of large-diameter or fully loaded tube belt conveyors.

[0006] For example, invention application CN117585357A discloses a belt conveyor correction device, which drives the correction rollers to move through a large gear ring disc. Its structure is complex, and the processing and installation costs of the large gear ring disc are high. Each correction roller can only be arranged on one side of the partition, which limits its applicability. At the same time, each correction roller is a whole device, so once a failure occurs, maintenance is complicated.

[0007] In addition to the above problems, the existing correction equipment on the market has low compatibility with the original trusses and partitions, making it difficult to retrofit and install on existing pipe belt conveyors, and the retrofit investment is large.

[0008] The challenge of effectively and conveniently correcting deviations during operation has always been a problem for tubular belt conveyors, which differ from ordinary belt conveyors. Summary of the Invention

[0009] The purpose of this invention is to provide an automatic correction device for a tubular belt conveyor that has a simple structure and good correction effect.

[0010] The purpose of this utility model is to achieve the following: An automatic deviation correction device for a tubular belt conveyor includes multiple detachable automatic deviation correction devices evenly distributed on the truss partition of the tubular belt conveyor. Each automatic deviation correction device includes an idler roller, an idler roller mounting frame, and an intelligent control device. The device is characterized by further including a U-shaped mounting frame, a connecting shaft, and a deviation correction assembly.

[0011] The U-shaped mounting bracket has a connecting end that connects to the truss partition of the conveyor belt structure, a support end for the correction component, and a U-shaped mounting bracket recess. Two bolt holes are symmetrically opened at the connecting end of the U-shaped mounting bracket. A shaft hole is opened at the center of the support end of the correction component, and mounting holes are arranged symmetrically around the shaft hole. A rotating shaft hole is opened in the U-shaped mounting bracket recess, and angular contact bearings are installed on the upper and lower sides of the rotating shaft hole using a double-support unidirectional fixing method.

[0012] The upper end of the connecting shaft adopts an external spline design, passes through the rotating shaft hole of the U-shaped mounting bracket recess, extends upward from the U-shaped mounting bracket, and the lower end is fixedly connected to the upper part of the idler roller mounting bracket;

[0013] The aforementioned correction assembly includes a swing arm and an electric push rod. The electric push rod is fixedly connected to the correction assembly support end of the U-shaped mounting bracket by bolts. One end of the swing arm adopts an internal spline design and is fixedly fitted onto the external spline of the connecting shaft, while the other side is a rotating plate with a slot. The electric push rod is fixedly installed on the correction assembly support end of the U-shaped mounting bracket by bolts. The telescopic lug end of the electric push rod passes through the shaft hole in the center of the correction assembly support end and is slidably connected to the slot in the swing arm by a pin, forming a linkage mechanism with the swing arm. The electric push rod is electrically connected to the intelligent control device.

[0014] As a further description of the above technical solution: the roller surface of the rotary support assembly roller is in contact with the bottom of the belt, and both ends of the roller are rotatably connected to the roller mounting frame to provide rolling support for the belt. The roller rotates with the extension and retraction of the electric push rod through the transmission of the swing arm and the connecting shaft.

[0015] As a further description of the above technical solution: two bolt holes are symmetrically opened at the connecting end of the U-shaped mounting bracket, which match the original fixed roller bolt holes on the truss.

[0016] As a further description of the above technical solution: the multiple detachable automatic correction devices evenly distributed on the truss of the tubular conveyor are arranged in a 3 / 3, 0 / 3 or 0 / 6 configuration.

[0017] The advantages of this utility model are:

[0018] Compared with the prior art, this utility model has a simple and compact structure, flexible installation and layout, high compatibility with the truss and partition of the tubular conveyor, and convenient and quick maintenance, disassembly and replacement of spare parts; it adopts electric push rod drive, and the correction response is fast.

[0019] This system employs multi-angle, multi-idler synchronous operation, resulting in high correction energy. Combined with a mature deviation switch and automated device, it enables unattended correction operations, achieving a high degree of automation. Therefore, this invention significantly reduces the time and labor intensity of correction operations for tubular conveyors, while avoiding safety accidents such as squeezing and impacts that are highly likely to occur during manual correction. It improves enterprise production efficiency and worker safety, and saves labor costs. Attached Figure Description

[0024] like Figures 1-4 As shown, this utility model discloses an automatic deviation correction device for a tubular belt conveyor, comprising multiple detachable automatic deviation correction devices evenly distributed on the truss partition of the tubular belt conveyor. Each automatic deviation correction device includes an idler roller 2, an idler roller mounting frame, and an intelligent control device. Its distinguishing feature is that it further includes a U-shaped mounting frame, a connecting shaft 7, and a deviation correction assembly.

[0025] The U-shaped mounting bracket has a connecting end 31 that connects to the truss partition plate 8 of the conveyor belt structure, a correction component support end 32, and a U-shaped mounting bracket recess 33. Two bolt holes 311 are symmetrically opened on the connecting end 31 of the U-shaped mounting bracket. A shaft hole 321 is opened in the center of the correction component support end 32, and mounting holes 322 are arranged symmetrically around the shaft hole. A rotating shaft hole is opened in the U-shaped mounting bracket recess 33, and angular contact bearings 6 are installed on the upper and lower sides of the rotating shaft hole using a double-support unidirectional fixing method.

[0026] The upper end of the connecting shaft 7 adopts an external spline design, passes through the rotating shaft hole of the U-shaped mounting bracket, extends upward from the recess 33 of the U-shaped mounting bracket, and the lower end is fixedly connected to the upper part of the idler roller mounting bracket 1.

[0027] The aforementioned correction assembly includes a swing arm 5 and an electric push rod 4. The electric push rod 4 is fixedly connected to the correction assembly support end 32 of the U-shaped mounting bracket by bolts. One end of the swing arm 5 adopts an internal spline design and is fixedly fitted onto the external spline of the connecting shaft. The other side is a rotating plate with a slot 51. The electric push rod 4 is fixedly installed on the correction assembly support end 32 of the U-shaped mounting bracket by bolts. The telescopic lug end of the electric push rod 4 passes through the shaft hole 321 in the center of the correction assembly support end and is slidably connected to the slot 51 in the swing arm 5 by a pin, forming a linkage mechanism with the swing arm 5. The electric push rod 4 is electrically connected to an intelligent control device (not shown in the figure).

[0028] As a further description of the above technical solution: the roller surface of the rotary support assembly roller is in contact with the bottom of the belt, and both ends of the roller are rotatably connected to the roller mounting frame to provide rolling support for the belt. The roller rotates with the extension and retraction of the electric push rod through the transmission of the swing arm and the connecting shaft.

[0029] As a further description of the above technical solution: The present invention has two bolt holes symmetrically opened at the connecting end 31 of the U-shaped mounting frame, which match the bolt holes for fixing the idler rollers on the truss partition plate 8.

[0030] As a further description of the above technical solution: the multiple detachable automatic correction devices evenly distributed on the truss partition plate 8 of the tubular conveyor are arranged in a 3 / 3, 0 / 3 or 0 / 6 type.

[0031] Figure 4 An embodiment is shown in which both the upward belt 9 and the downward belt 10 adopt a 3 / 3 arrangement. The 0 / 3 or 0 / 6 arrangement can be flexibly arranged according to the working conditions, process, cylinder diameter, belt speed and other influencing factors of the tubular belt conveyor. In this way, the equipment has multiple correction angles and large correction energy.

[0032] Its working principle is:

[0033] When the automatic correction device of the tubular belt conveyor of this utility model is powered on and the tubular belt conveyor is in operation, multiple belt deviation detection elements are set on the tubular belt conveyor to collect the actual position of the conveyor belt in real time. After the intelligent control device diagnoses the signals collected by the belt detection elements, it can identify the belt deviation signal and intelligently diagnose the degree of belt deviation, and output a correction command adapted to the degree of deviation. The electric push rod 4 can convert the correction command adapted to the degree of deviation into the extension and retraction of the electric cylinder output end, which drives the idler roller mounting frame to rotate through the swing arm, thereby achieving the purpose of automatically completing the correction action.
