Description

Technical Field

[0001] This utility model relates to the field of traction equipment technology, specifically a roller-type traction device. Background Technology

[0002] Currently, industrial and mining enterprises generally use belt conveyors when they need to transport large quantities of materials. With the gradual increase in production capacity and factors such as energy conservation, emission reduction, and carbon reduction, the length of belt conveyors is also increasing, gradually replacing ordinary transportation methods such as road transport. Belt conveyor applications have seen the emergence of off-road conveyors that are several kilometers or even tens of kilometers long.

[0003] In order to ensure the normal operation of the equipment and production safety, the conveyor belt of a belt conveyor needs to be replaced during initial installation and after a certain number of years of use. This requires traction of the conveyor belt. Because the conveyor belt of a belt conveyor is long and heavy, the traction force of ordinary winches is small and cannot stably carry out traction work on long and heavy conveyor belts.

[0004] In view of this, there is an urgent need for a roller-type traction device to solve the above problems. Utility Model Content

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0021] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0022] like Figures 1-3As shown, a roller-type traction device includes: a frame, on which a first roller 1, a second roller 2, a pressure roller 3, a drive mechanism, and an adjustment mechanism are arranged. The first roller 1, the second roller 2, and the pressure roller 3 are aligned axially. The first roller 1 and the second roller 2 are both cast and welded structures with axial and radial reinforcing ribs arranged inside. The outer surface of the roller is covered with a covering layer, which is mainly made of rubber-based materials, combined with other materials that can increase friction, and with certain patterns to improve the friction coefficient of the roller surface. The first roller 1 and the second roller 2 are arranged horizontally, and the drive mechanism is used to drive the first roller 1 and / or the second roller 2 to rotate. The pressure roller 3 is located on the ring side of the first roller 1, and the adjustment mechanism is used to adjust the distance between the axis of the pressure roller 3 and the axis of the first roller 1.

[0023] Based on the above structure, in use, the conveyor belt 17 to be pulled is laid in an S-shaped trajectory on the first roller 1 and the second roller 2 (e.g., Figure 3 As shown, the position of the clamping roller 3 is adjusted by the adjusting mechanism, so that the conveyor belt 17 is clamped between the hydraulic clamping roller 3 and the first roller 1. The first roller 1 and / or the second roller 2 are driven to rotate by the driving mechanism. The first roller 1 and the second roller 2 rotate in opposite directions to pull the conveyor belt 17. The driving mechanism can drive the first roller 1 or the second roller 2 to rotate alone (with less traction force), which is suitable for the traction of lighter and shorter conveyor belts. The driving mechanism can also drive the first roller 1 and the second roller 2 to rotate at the same time (with greater traction force), which is suitable for the traction of heavier and longer conveyor belts. The specific choice should be made according to the actual traction situation.

[0024] like Figure 3As shown, the conveyor belt 17 enters between the two limiting rollers 4, passes under the first roller 1, then goes around the second roller 2 away from the first roller 1, passes through the bottom of the first roller, and finally goes around the first roller 1 and exits from the side of the second roller 2. In order to better guide the conveyor belt 17 into the frame, the frame is provided with two limiting rollers 4 on the side of the first roller 1 away from the second roller 2. The axial direction of the two limiting rollers 4 is consistent with the axial direction of the first roller 1. The two limiting rollers 4 are arranged sequentially from top to bottom, specifically at the line connecting the lowest circumferential position of the upper limiting roller 4 and the lowest circumferential position of the second roller 2. Below the lowest circumferential position of the first roller 1, the conveyor belt 17 will not contact the portion of the conveyor belt wound on the first roller 1 when it passes under the first roller 1, thus affecting the traction of the conveyor belt. Furthermore, a support roller 5 is provided on the side of the frame and the second roller 2 away from the first roller 1. The axial direction of the support roller 5 is consistent with the axial direction of the second roller 2. Specifically, the line connecting the highest circumferential position of the support roller 5 and the highest circumferential position of the first roller 1 is higher than the highest position of the second roller 2. Thus, when the conveyor belt 17 passes through the frame above the second roller 2, it will not contact the portion of the conveyor belt wound on the second roller 2.

[0025] like Figure 1 and Figure 2 As shown, in order to achieve selective driving of the first roller 1 and the second roller 2, two drive mechanisms are provided. The two drive mechanisms are used to drive the first roller 1 and the second roller 2 to rotate respectively. The drive mechanism specifically includes a motor 6 and a planetary reducer 7. The motor 6 and the planetary reducer 7 are mounted on the frame. The output end of the motor 6 is connected to the planetary reducer 7. The output end of the planetary reducer 7 is coaxially connected to the first roller 1 or the second roller 2. In this way, the motor 6 and the planetary reducer 7 can be connected by a coupling to drive the first roller 1 or the second roller 2 to rotate.

[0026] like Figure 1 and Figure 2 As shown, the frame includes two support frames 8, which are arranged side by side by bolts. The first roller 1 and the second roller 2 are respectively mounted on the two support frames 8. Two drive mechanisms are respectively mounted on the two support frames 8. The adjustment mechanism and the first roller 1 are mounted on the same support frame 8. In this way, the two support frames 8 can be separated so that the first roller 1 can be used alone to pull the conveyor belt. Specifically, the conveyor belt can be wound around the first roller 1, and the conveyor belt can be pressed onto the first roller 1 by the pressure roller 3. The rotation of the first roller 1 can pull the conveyor belt.

[0027] like Figure 2 and Figure 4As shown, the adjustment mechanism includes a rotating shaft 9, two connecting parts, and a drive assembly. The rotating shaft 9 is mounted on the frame, and its axial direction is aligned with that of the pressure roller 3. The connecting parts are provided with a first connecting end 10, a second connecting end 11, and a third connecting end 12. The connecting parts are connected to the rotating shaft 9 via the first connecting end 10. The second connecting end 11 and the third connecting end 12 are both located around the rotating shaft 9. The two ends of the pressure roller 3 are respectively located on the two second connecting ends 11. The drive assembly is mounted on the frame and is connected to the third connecting ends 12 of the two connecting parts. It is used to drive the connecting parts to rotate around the rotating shaft 9. Thus, by driving the connecting parts to rotate around the rotating shaft 9, the second connecting ends 11 are moved closer to or further away from the first roller 1, thereby adjusting the distance between the axis of the pressure roller 3 and the axis of the first roller 1, pressing the conveyor belt, and adapting to the traction of conveyor belts of different thicknesses.

[0028] To improve the compaction effect, such as Figure 4 As shown, there are two pressing rollers 3. A connecting plate 13 is provided on the second connecting end 11. The two pressing rollers 3 are respectively set on the two connecting plates 13 at their two ends.

[0029] like Figure 2 and Figure 4 As shown, the drive assembly includes two hydraulic cylinders 14 mounted on the frame. The output ends of the two hydraulic cylinders 14 are respectively connected to two third connection ends 12. Thus, the hydraulic system drives the two hydraulic cylinders 14 to work synchronously, tightening or pushing the third connection ends 12, causing the connecting parts to rotate. Specifically, the hydraulic system consists of a hydraulic station motor connected to a hydraulic oil tank via a connecting seat, which transmits power to a hydraulic pump. The hydraulic pump converts kinetic energy into hydraulic energy, which is then delivered to an energy storage device through a valve body. When the pressure in the energy storage device reaches a certain value... Then, hydraulic oil is delivered to hydraulic cylinder 14 via hydraulic oil pipe through the valve body. At this time, the hydraulic cylinder has a tensioning action. At the same time, the hydraulic oil return port flows through the hydraulic oil pipe, through the valve body, and then to the hydraulic oil tank. When the hydraulic oil pipe returns oil and oil enters the pipe, the hydraulic cylinder begins to extend. The hydraulic cylinder drives the connecting part to rotate around the rotating shaft. When the connecting part rotates, it drives the connecting plate 13 to move counterclockwise. The connecting plate 13 transmits force to the pressure roller. The pressure roller leaves the conveyor belt. At this time, it is in the loosened state. This indicates that the work is completed or the conveyor belt can be pulled out and replaced with another conveyor belt that needs to be pulled.

[0030] like Figure 3 and Figure 5As shown, to prevent the conveyor belt 17 from shifting in the axial position of the first roller 1, a guide roller mechanism is provided on the side of the first roller 1 and the second roller 2 that are far apart from each other. The guide roller mechanism includes a truss 15 and two guide rollers 16. The truss 15 is set on the frame, and the axial direction of the two guide rollers 16 is perpendicular to the axial direction 2 of the pressure roller 3. When the conveyor belt 17 enters and exits the frame, it passes between the two guide rollers 16 of the corresponding guide roller mechanism. The position of the conveyor belt 17 is restricted from both sides by the two guide rollers 16 to prevent the conveyor belt from running off-center. In addition, two sets of clamping plates 18 are provided on the truss 15. Each set of clamping plates 18 includes two clamping plates 18 arranged from top to bottom. Several clamping slots are provided on the clamping plates 18 (several clamping slots are arranged along the axial direction of the first roller 1). The two ends of the guide rollers 16 are respectively clamped in the clamping slots of the two clamping plates 18 in the same set. In this way, the guide rollers 16 are clamped in different clamping slots, so that the distance between the two guide rollers 16 is different, which is suitable for the traction of conveyor belts of different widths.

[0031] In summary, during use, the conveyor belt 17 to be pulled is laid on the first roller 1 and the second roller 2 in an S-shaped trajectory. The position of the pressure roller 3 is adjusted by the adjusting mechanism so that the conveyor belt 17 is clamped between the hydraulic pressure roller 3 and the first roller 1. The first roller 1 and / or the second roller 2 are driven to rotate by the drive mechanism. The first roller 1 and the second roller 2 rotate in opposite directions to pull the conveyor belt 17. The drive mechanism can drive the first roller 1 or the second roller 2 to rotate alone, which is suitable for pulling lighter and shorter conveyor belts. The drive mechanism can also drive the first roller 1 and the second roller 2 to rotate simultaneously, which is suitable for pulling heavier and longer conveyor belts. The appropriate method should be selected according to the actual traction situation. This application addresses the need for high traction force during the installation and replacement of long and wide conveyor belts, and can fully meet the on-site traction force requirements. This application features a compact structure that can be disassembled and assembled according to site requirements, occupies a small area, and is easy to transport; The components used in this application are mature, capable of continuous operation, highly efficient, and stable in performance. This application has a long service life, is easy to maintain and operate.

[0032] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
