Description

Technical Field

[0001] This utility model relates to the field of idler roller replacement technology, specifically to an idler roller replacement device. Background Technology

[0002] The function of idlers on a belt conveyor is to support the conveyor belt and the weight of the materials. Idler rollers must be in good condition to prevent damaged rollers from scratching the conveyor belt surface. They must also ensure flexible rotation to reduce friction between the conveyor belt and the rollers. This plays a crucial role in extending the lifespan of the conveyor belt, which accounts for over 25% of the total cost of the conveyor. Replacing idlers during routine maintenance in the mechanical parts workshop is time-consuming, especially when replacing upper conveyor rollers. Existing support tools are mostly fixed in place, preventing positional adjustments during operation and hindering flexible adjustments based on the actual position and tilt angle of the idler roller.

[0013] Preferably, a fixing plate is fixedly connected to one side of the fixing slot, and the fixing plate is threadedly connected to the adjusting screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the sliding setting of the arc plate on the outside of the fixed slot and the sliding adjustment of the moving slider on the arc plate allow the position and angle of the supporting top plate to be flexibly adjusted according to the actual position and tilt angle of the idler roller; the introduction of the hydraulic cylinder enables the supporting top plate to accurately and powerfully lift the belt, providing stable support for the replacement of the idler roller; at the same time, by rotating the adjusting screw, the position of the arc plate and the supporting top plate can be precisely controlled to achieve precise support at the specified position; the sliding connection between the guide rail and the arc plate, and the cooperation between the limiting groove and the moving slider, not only enhance the structural strength of the tool, but also improve its stability during operation.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , 2As shown in Figure 3, this utility model provides a technical solution: a roller replacement device, comprising: a fixed slot 1, the fixed slot 1 having an n-shaped structure, and fasteners provided on the outer side of the fixed slot 1; an arc plate 6 slidably mounted on the outer side of the fixed slot 1, a movable slider 8 slidably disposed on the outer side of the arc plate 6, and a positioning bolt 9 for positioning provided on the outer side of the movable slider 8; an adjusting screw 12 placed on the outer side of the fixed slot 1 for driving the arc plate 6 to slide; and a hydraulic cylinder 3 placed on top of the movable slider 8, with a supporting top plate 4 fixedly connected to the output end of the hydraulic cylinder 3.

[0021] It should be noted that the hydraulic cylinder 3 of this utility model is a small jack. The fixing slot 1 is clamped onto the equipment bracket below the idler roller that needs to be replaced, so that one end of the fixing slot 1 abuts against the support frame of the idler roller. The fixing slot 1 is fixed to the equipment bracket by fasteners. According to the tilt angle of the idler roller, the angle of the moving slider 8 on the outside of the arc plate 6 is adjusted. After the adjustment is completed, the moving slider 8 is fixed by the positioning bolt 9. Then, the driving hydraulic cylinder 3 drives the support top plate 4 to rise, so that the support top plate 4 lifts the belt. As needed, the arc plate 6 is slid on the outside of the fixing slot 1 by rotating the adjusting screw 12. In this way, the support top plate 4 supports the required position, so that the support position can be flexibly adjusted.

[0022] Please see Figure 1 , 2 As shown, the fastener is a fastening bolt 10, which is threaded to both ends of the fixing slot 1 and extends into the interior of the fixing slot 1 to press and fix the fixing slot 1.

[0023] It should be noted that in this utility model, the fixing slot 1 is clamped onto the equipment bracket. By tightening the fastening bolt 10, one end of the fastening bolt 10 moves into the fixing slot 1 and makes compression contact with the equipment bracket, thereby fixing the fixing slot 1 in the designated position. The position of the supporting top plate 4 can be adjusted as needed.

[0024] Please see Figure 2 , 3 As shown, a guide rail 5 is fixedly connected to the top of the fixed slot 1, and an arc plate 6 is slidably connected to the guide rail 5. Grooves that mate with the arc plate 6 are provided on both sides of the arc plate 6. Multiple positioning holes 13 that mate with the positioning bolts 9 are equidistantly opened on one side of the arc plate 6. A limiting groove 7 concentric with the arc plate 6 is opened in the middle of the arc plate 6. The movable slider 8 is slidably connected to the limiting groove 7. A fixed plate 11 is fixedly connected to one side of the fixed slot 1. The fixed plate 11 is threadedly connected to the adjusting screw 12.

[0025] It should be noted that when adjusting the angle of the hydraulic cylinder 3, the movable slider 8 slides on the outside of the arc plate 6. At this time, the middle part of the movable slider 8 slides in the limiting groove 7. When the movable slider 8 slides to the designated position, the positioning bolt 9 is rotated so that its top is inserted into the positioning hole 13. In this way, the position of the supporting top plate 4 is fixed by the positioning bolt 9 and the arc plate 6. After the fixation is completed, when the position of the arc plate 6 needs to be adjusted, the adjusting screw 12 is rotated. The adjusting screw 12 is threadedly connected to the fixing plate 11. Under the action of the fixed thread, the adjusting screw 12 drives the arc plate 6 to slide on the outside of the fixing groove 1, so that it can support the designated position according to the disassembly requirements.

[0026] Please see Figure 1 As shown, the top of the movable slider 8 is fixedly connected to the support plate 2, and the bottom of the oil cylinder 3 is fixedly connected to the support plate 2.

[0027] It should be noted that this utility model adjusts the position and angle of the oil cylinder 3 by moving the slider 8 and the support plate 2. The oil cylinder 3 is a hydraulic jack. When adjusting the extension, when hydraulic oil is sent through the handle, the hydraulic oil will be pressed into the oil cylinder, generating pressure and pushing the piston to move upward.
