Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor rollers, specifically, it relates to an auxiliary device for replacing belt conveyor rollers. Background Technology

[0002] If the bearings of belt conveyor idlers are damaged or the rubber rings are excessively worn, failure to replace the idlers in a timely manner will severely affect the reliability of the belt conveyor operation, easily causing scratches or even tearing of the belt. During idler replacement, the belt needs to be lifted to a certain distance from the idler. The belt is pressed against the idler by a screw tensioning device or a counterweight tensioning device, resulting in relatively high belt tension, making it difficult to detach the belt from the idler to be replaced. Current technology mainly involves multiple people working together to replace idlers, with one person holding the belt with tools while another person replaces the idler. This method is labor-intensive, prone to accidents, and has low safety standards.

[0003] To address the aforementioned problems, patent document No. 214383536U provides an auxiliary tool for replacing idler rollers, relating to the field of belt conveyor maintenance equipment. It is designed to solve the significant safety hazards inherent in existing belt lifting methods. This auxiliary tool for replacing idler rollers includes a support beam with a first support and a second support fixedly at intervals along its length. The first support has a first support surface parallel to the horizontal plane, and the second support has a second support surface at an angle to the horizontal plane. The support beam has a first side and a second side opposite to each other along its width. The second support surface extends upwards and slopes towards the first side. A top leg is fixedly mounted on the first side, the end of which abuts against the longitudinal column of the idler roller frame. A lifting device can be placed on both the first and second support surfaces, but this does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, an auxiliary device for replacing idlers on a belt conveyor is provided, which can support the belt so that the belt can be separated from the idler, which is conducive to improving the efficiency of idler replacement, reducing labor costs and labor intensity, and improving the safety of the idler replacement process.

[0028] like Figure 2 As shown, the movable rod 12 has a movable groove 13 at one end away from the support rod 11, and a first connecting hole 14 is provided on the movable groove 13. The movable groove 13 and the first connecting hole 14 are used to realize the movable rod 12 and the support assembly 20 to movably connect, so that the support rod 11 can be supported by the support assembly 20.

[0029] Figure 3 This is a schematic diagram of the support rod in an embodiment of this utility model;

[0030] like Figure 3 As shown, the support assembly 20 includes a support base 21 and a support rod 22. The support rod 22 is movably connected to the support base 21. The support base 21 is mounted on the idler roller base frame. The support rod 22 and the support base 21 are rotatably connected by a hinge. One end of the support rod 22 is provided with a movable protrusion 23 that matches the movable groove 13. The movable protrusion 23 is movably mounted in the movable groove 13. The movable protrusion 23 is provided with a second connecting hole 24. A rotating shaft 30 passes through the first connecting hole 14 and the second connecting hole 24, thereby enabling the support rod 22 and the movable rod 12 to be rotatably connected. This facilitates the lifting of the belt by the support rod 11, making it convenient to replace the idler roller and improving the idler roller replacement efficiency.

[0031] The support base 21 is provided with a slot 25, which is a flat-bottomed slot or an irregularly shaped slot that is compatible with the profile of the idler base frame. This makes it easy to lock the support base 21 onto the idler base frame. The inner wall of the slot 25 is polished to increase the friction between the support base 21 and the idler base frame, preventing the support base 21 from shifting during the belt lifting process. This improves the stability of the support assembly 10, enhances the safety during the roller changing process, and increases the reliability of the structure.

[0032] The support base 21 is provided with a locking screw 26, which is rotatably inserted into the support base 21. The end of the locking screw 26 is located in the slot 25 and abuts against the profile of the idler base frame, thereby further improving the stability of the support base 21 on the idler base frame, further preventing the support base 21 from shifting during the belt lifting process, improving the stability of the support assembly 10, improving the safety during the roller changing process, and improving the reliability of the structure.

[0033] A rubber sleeve 27 is provided at the end of the support rod 22 away from the support assembly 10. The rubber sleeve 27 is fitted onto the end of the support rod 22. The end of the support rod 22 away from the support assembly 10 abuts against the idler base frame, thereby supporting the support assembly 10. The rubber sleeve 27 can enhance the friction between the end of the support rod 22 and the idler base frame, thereby preventing the end of the support rod 22 from shifting during the belt lifting process, improving the stability of the support assembly 10, improving the safety during the roller changing process, and improving the reliability of the structure.

[0034] Figure 4 This is a schematic diagram of the structure of the auxiliary device for replacing the idler rollers on the belt conveyor with an extension sleeve in an embodiment of this utility model.

[0035] like Figure 4 As shown, the end of the support rod 22 away from the support assembly 10 is provided with an extension sleeve 28. The extension sleeve 28 is sleeved on the end of the support rod 22 to extend the length of the support rod 22 and increase the lever arm when the support rod 22 lifts the support assembly 10, thereby lifting the belt more effortlessly and reducing labor intensity.

[0036] When replacing idlers using the auxiliary device for replacing idlers on a conveyor belt provided by this utility model, the operator places the support base 21 onto the idler base frame, presses the end of the support rod 22 away from the support component 10, thereby lifting the support component 10. The support rod 11 lifts the belt, and the end of the support rod 22 with the rubber sleeve 27 is pressed tightly against the idler base frame. The support component 10 and the support component 20 are kept in balance, stably supporting the belt. Tightening the locking screw 26 fixes the support base 21 to the profile of the idler base frame, thereby maintaining the stability of the support component 10 and the support component 20. This allows for easy single-person replacement of idlers, improves idler replacement efficiency, reduces labor costs and labor intensity, and enhances safety during the idler replacement process.
