Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, and in particular relates to an auxiliary installation device for belt replacement of belt conveyors. Background Technology

[0002] A belt conveyor is an industrial conveying device used for long-distance material transport. Its main structure includes a frame, a head frame and a tail frame on which belt drums are installed respectively, a belt driving between the belt drums, and an idler structure on the frame that supports the bottom of the belt. The idler structure is arranged in a V-shape, that is, it includes inclined rollers located on both sides of the idler frame and horizontal rollers located at the center of the roller frame, forming a V-shaped support structure.

[0003] The belt is made of rubber, and as it ages, it ages significantly, wears more, and may even tear. Therefore, current technology dictates that old belts must be replaced. The method involves removing the old belt (by first loosening the tension screw on the tailstock, which further loosens the belt), then hoisting the new belt roll. The free end of the belt is secured with a steel wire rope, specifically by passing the wire rope through and fixing it to the free end of the belt. The free end of the wire rope is wound around the belt drum of the conveyor. The new belt is dragged along the conveyor by slowly winding the wire rope around the drum, with the belt supported by idler rollers during the dragging process.

[0004] However, the drawbacks of this method are as follows: First, the belt is made of rubber, and the steel wire rope needs to be pre-drilled through holes in the belt to be hung on it, which damages the integrity of the belt (this is the only way to fix the steel cable). Second, especially for long belt conveyors, the total length of the belt is relatively large, and the pulling force is very large. The steel wire rope is stuck on the belt, which further makes the belt easy to be damaged.

[0005] Secondly, during the pulling process, the pulling end of the belt is supported on the idler rollers (the idler rollers play a protective role in the operation of the belt conveyor). As the new belt is pulled, it is dragged along all the idler rollers on the frame. The frictional resistance of the idler rollers is very large, especially for large belt conveyors. Therefore, replacing a belt is not only very time-consuming and laborious, but also often requires the cooperation of multiple people. At the same time, the friction of the idler rollers causes the pulling end of the belt to be severely obstructed during the pulling process, making the pulling even more difficult.

[0006] Based on the above background, the purpose of this utility model is to provide an auxiliary installation device for belt replacement of belt conveyors.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A belt replacement auxiliary installation device for a belt conveyor includes a locking mechanism that locks at the free end of the belt; the locking mechanism includes brackets on both sides, and a guide roller for the guide belt is fixedly connected between the brackets.

[0009] It also includes a cap structure that works with the guide roller, the cap structure being used to lock the belt onto the guide roller;

[0010] It also includes a roller structure installed at the bottom of the bracket to support the roller structure that rolls on the belt conveyor.

[0017] Preferably, a connecting beam is fixedly connected between the end frames, and the tensioning structure includes a tensioning screw welded and fixed to the connecting beam;

[0018] The top and bottom sides of the arc-shaped pressure cap are respectively fixedly connected to the bosses that are slidably connected to the tensioning screw, and the outer end of the tensioning screw is threadedly connected to a nut that is locked to the outside of the bosses.

[0019] Preferably, a bottom connecting beam is fixedly connected between the end frame portions located at the bottom;

[0020] The roller structure is mounted on the bottom connecting beam.

[0021] Preferably, the roller structure includes a pair of inclined rollers that are respectively inclined outwards; the inclined rollers are arranged perpendicularly to the inclined rollers of the belt conveyor roller structure;

[0042] Example 1

[0043] like Figure 1-5 As shown, a belt replacement auxiliary installation device for a belt conveyor includes a locking mechanism 2 that locks at the free end of the belt; the locking mechanism 2 includes brackets 21 arranged on the left and right sides, and a guide roller 23 for guiding the belt is fixedly connected between the brackets 21 (the guide roller 23 can also be designed in a rotating connection manner according to the existing method, specifically, the two ends of the guide roller 23 are fixed with rotating shafts, and the rotating shafts are rotatably connected to the brackets).

[0044] Specifically, the support 21 includes a central support portion 212 located at the center, and end bracket portions 211 are fixedly connected to the top and bottom of the central support portion 212 respectively; guide rollers 23 are fixedly connected between the central support portions 212.

[0045] Meanwhile, the locking mechanism 2 also includes a cover structure that cooperates with the guide roller 23, the cover structure being used to lock the belt onto the guide roller 23.

[0046] Specifically, guide brackets 22 with guide belts are fixedly installed between the upper and lower ends of the bracket, and rectangular guide holes are opened on the guide brackets 22; mounting rods are fixedly connected to both ends of the guide brackets 22, and the mounting rods are fixedly installed on the end frame 211.

[0047] The pressure cap structure includes an arc-shaped pressure cap 26 that mates with the guide roller 23; the top and bottom of the arc-shaped pressure cap 26 are respectively locked by a tensioning structure. A connecting beam is fixedly connected between the end frame portions 211, and the tensioning structure includes a tensioning screw 25 welded and fixed to the connecting beam; the top and bottom sides of the arc-shaped pressure cap 26 are respectively fixedly connected to a boss 261 that is slidably connected to the tensioning screw 25, and the outer end of the tensioning screw 25 is threadedly connected to a nut that is locked to the outside of the boss 261.

[0048] During operation, first loosen the arc-shaped cover 26, pass the free end of the belt through the rectangular guide hole of the guide bracket 22 at the top position, then move the belt vertically downward (avoiding the connecting beam, between the connecting beam and the guide bracket 22), then guide it through the outside of the guide roller 23, and finally pass it through the guide bracket 22 at the bottom position (again avoiding the connecting beam).

[0049] At this point, the arc-shaped pressure cap 26 is pushed toward the guide roller 23. With the cooperation of the guide roller 23 and the arc-shaped pressure cap 26 (the arc-shaped cavity of the arc-shaped pressure cap 26), the free end of the belt forms an arc shape (increasing the compression contact area and protecting the belt) and is squeezed between the guide roller 23 and the arc-shaped pressure cap 26. Then, the nut is squeezed inward until the arc-shaped pressure cap 26 is locked.

[0050] This method locks the free end of the belt, securing it non-destructively. During subsequent pulling, the use of the arc-shaped pressure cap 26 and guide roller 23 for positioning ensures a large locking area, reducing the risk of belt damage. This method also protects the belt during replacement by securing the free end and providing more stable belt pulling.

[0051] Example 2

[0052] like Figure 1-5As shown, in this embodiment, based on the structure of Embodiment 1, pull rings 231 for hanging steel cables are welded onto the central support portion 212. According to conventional methods, steel cables are hung on the pull rings 231 at both ends. The free ends of the steel cables are wound around the drive drum of the belt conveyor (the drive drum with a drive structure installed on the head frame of the belt conveyor). In this way, the drive drum is used to wind and pull the steel cables, thus achieving a highly flexible method for pulling and installing the belt.

[0053] Example 3

[0054] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 2. In the traditional method of pulling the belt, the belt (free end) is dragged on the belt conveyor roller structure and is affected by the frictional resistance of multiple roller structures. The resistance of the free end of the belt is very large. Therefore, this utility model reduces the dragging resistance by improving the structure.

[0055] Specifically, it also includes a roller structure installed at the bottom of the bracket to support the roller structure that rolls on the belt conveyor.

[0056] A bottom connecting beam 27 is fixedly connected between the end frame portions 211 located at the bottom (the top of the bottom connecting beam 27 is fixedly installed at the bottom of the end frame portion 211 by a fixing rod).

[0057] The roller support structure is mounted on the bottom connecting beam 27. The roller support structure includes a pair of outward-inclined rollers (the outward-inclined rollers are arranged in a V-shape, specifically in an inclined manner to match the posture of the conveyor belt's roller structure). Specifically, the rollers roll against the inclined rollers on both sides of the roller structure.

[0058] Specifically, the inclined roller is set perpendicular to the inclined roller of the belt conveyor idler structure; similarly, it also includes a vertically set vertical roller, which is set perpendicular to the horizontal roller of the belt conveyor idler structure.

[0059] The aforementioned inclined support roller and vertical support roller both include a support roller bracket 28, on which a support roller is rotatably connected; the support roller bracket 28 is fixedly installed on the bottom connecting beam 27 through an adjustment structure.

[0060] Meanwhile, the adjustment structure includes an adjustment screw 281 fixedly connected to the bottom connecting beam 27, an adjustment screw 281 slidably connected to the roller support bracket 28, and a pair of locking nuts 2811 threadedly connected to the adjustment screw 281 and positioned on the roller support bracket 28.

[0061] By adjusting the structure, the distance between the inclined and vertical support rollers and the conveyor belt idler rollers is adjusted during operation to ensure that the inclined and vertical support rollers roll vertically on the conveyor belt. The operation method is as follows: loosen the locking nut 2811 and then slide to adjust until the inclined and vertical support rollers support and roll on the idler rollers.

[0062] In the prior art: one end of the steel cable is wound on the driving drum of the belt conveyor and guided by the driven drum of the belt conveyor. The other end of the steel cable is fixed on the free end of the belt. After the belt roll is unwound and stretched, the upper belt is first pulled along the idler roller through the driven drum. Then, it passes through the bottom of the driven drum and is pulled toward the driving drum.

[0063] However, due to the very high frictional resistance of the idler rollers, pulling them is extremely difficult in actual operation.

[0064] With the device disclosed in this utility model, during actual operation, after the arc-shaped pressure cover 26 is loosened to unlock the belt (at this time, the entire device and the free end of the belt in the locked state are close to the driven drum of the belt conveyor), the entire device can be slid along the length of the belt to the far end of the belt, and then the belt can be locked and pulled. At this time, the operator can easily pull the free end of the belt along the bottom guide of the driven drum to the driving drum (the upper belt is supported on the idler roller and is difficult to pull, while the lower belt passes under the idler roller and is easy to pull).

[0065] In actual operation, the aforementioned support roller structure can also be disassembled from the bottom connecting beam 27 (the adjusting screw 281 is threadedly connected to the bottom connecting beam 27). When pulling past the driven belt drum, the operator assists in raising the belt to allow the entire device to pass over the obstacle of the driven belt drum and continue pulling to the position of the driving belt drum.

[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
