Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor maintenance equipment, specifically relating to an auxiliary device for replacing belt conveyor idlers. Background Technology

[0002] Belt conveyors are indispensable equipment in modern industrial production, widely used in mining, metallurgy, chemical, and power industries. Idler rollers, as key components of belt conveyors, directly affect the stability and safety of the entire conveying system. However, in actual production, idler rollers are prone to wear and jamming due to prolonged high-load operation, requiring regular replacement.

[0003] Traditional idler replacement methods rely primarily on manual operation, which presents the following problems: 1. High labor intensity: Operators need to use tools such as pry bars and hand-operated hoists to pry open the belt, making the entire process time-consuming and labor-intensive. 2. Poor safety: Manual operation easily leads to belt damage and poses risks of personnel injury and equipment falls. 3. Low efficiency: Replacing a set of idlers typically requires 3-4 people working together, taking about 20 minutes, severely impacting production efficiency. 4. Belt conveyor idler auxiliary replacement device: Structure: Includes a support frame and a support rod device. Working principle: Uses the lever principle to lift the belt. Main effect: Improves idler replacement efficiency and reduces the burden of manual prying. Limitations: Insufficient support stability for wide-bandwidth or high-tension belts; operation still requires multiple people. 5. Auxiliary device for replacing belt conveyor idlers: Structure: Uses a horizontal hand-cranked screw jack mechanism. Working principle: Lifts the belt through the screw jack. Main effect: Reduces operational difficulty and physical exertion. Limitations: Slow adjustment speed, limited support height, and poor adaptability to different belt widths.

[0004] To address the aforementioned problems, those skilled in the art have undertaken numerous innovations. Existing technologies disclose auxiliary devices for replacing idler rollers on belt conveyors, which utilize the lever principle to lift the belt, thus improving replacement efficiency. Other methods utilize horizontal hand-cranked auger jacks to lift the belt, reducing operational difficulty.

[0005] Although existing technologies offer a variety of idler replacement aids, the following shortcomings remain: 1. Complex structure: Some devices contain too many parts, making installation and operation cumbersome. 2. Limited adaptability: Some devices are only suitable for replacing specific types or locations of idlers. 3. Insufficient portability: Some devices are large in size, making them inconvenient to carry and operate on-site.

[0006] The present invention aims to overcome the shortcomings of the prior art and provide a belt idler replacement auxiliary device that is simple in structure, easy to operate, highly adaptable and easy to carry, so as to improve the replacement efficiency of idlers, reduce labor intensity and ensure work safety.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-3 As shown, an auxiliary device for replacing the idler rollers of a belt conveyor includes a support beam 1, a base 2 slidably mounted on the support beam 1, a lifting device 6 connected to the base 2, the lifting device 6 including a lower support rod 61, two lower support rods 61 respectively hinged to both ends of the base 2, an upper support rod 62 hinged to the end of the lower support rod 61, a top seat 64 hinged to the end of the two upper support rods 62, a top beam 4 detachably mounted above the top seat 64, the hinge joints of the upper support rods 62 and the lower support rods 61 are connected by hinge shafts 65, and a screw 63 is threaded through the two hinge shafts 65.

[0023] Two limiters 3 are provided on the supporting crossbeam 1, and each limiter 3 has a locking component. The base 2 is located between the two limiters 3. One end of the screw 63 is connected to a sleeve 5, and the sleeve 5 is connected to an electric wrench. The top seat 64 has holes, and the top beam 4 can be adjusted and fixed at multiple angles by bolts passing through the holes. The surface of the top beam 4 has anti-slip texture.

[0024] Example 1 A stable rectangular frame structure is formed by a parallel supporting beam 1 and limiters 3 at both ends of its upper surface. The limiters 3 are equipped with locking components to lock the supporting beam 1 in place after it is fixed to the conveyor belt roller frame. The supporting beam 1 and the limiters 3 are perpendicular to each other, and the supporting beam 1 and the limiters 3 are detachably connected. The lifting device 6 is a modified 2T hand-cranked jack, mounted on the supporting beam 1, including a base 2 slidably mounted on the supporting beam 1. The base 2 and the supporting beam 1 are in a clearance sliding fit, ensuring that the sliding base 2 can slide stably along the supporting beam 1. The top seat 64 at the top of the lifting device 6 is detachable and can be angled to mount a top beam 4, adapting to different angle conditions. The length of the top beam 4 is adapted to the width of the belt. An M16 / 24 sleeve 5 is connected to one end of the screw 63, and the sleeve 5 is fitted with a lithium battery-powered electric wrench for rapid rotational adjustment. All components of this device are made of high-strength steel.

[0025] The operating steps for replacing the upper idler roller are as follows: 1. Adjust the support beam 1 and limiter 3 to match the belt frame, place them on the belt frame, and lock the limiter 3. 2. Install the slider on the base 2 onto the end face of the support beam 1. The slider on the base 2 is fixed to the support beam 1 with a clearance fit. Slide it back and forth to ensure a stable fit between the base 2 and the support beam 1. 3. Slide the base 2 to the position where the idler needs to be replaced. Use an electric wrench to rotate the sleeve 5 clockwise. The sleeve 5 drives the screw 63 to rotate, increasing the hinge angle between the upper support rod 62 and the lower support rod 61, thus raising the top beam 4 and lifting the belt support plate, causing the belt to leave the idler. 4. After the belt is lifted, remove and replace the damaged idler. 5. After replacement, use an electric wrench to rotate the sleeve 5 counterclockwise, decreasing the hinge angle between the upper support rod 62 and the lower support rod 61, thus lowering the top beam 4 and restoring the belt to its original position. Then remove the base 2 and the support beam 1.

[0026] The steps for adjusting the belt support height are as follows: 1. Adjust the limiter 3 to the required position according to the width of the belt support, and install the support beam 1 onto the belt support. 2. Rotate the sleeve 5 to raise the lifting device 6 to the appropriate height as needed. 3. After reaching the required height, stop rotating and keep the lifting device 6 stable. This completes the belt support height adjustment operation.
