Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to an online quick disassembly and assembly device for a belt conveyor roller. Background Art

[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It is widely used in the transportation of materials such as coal, gravel, sand, cement, fertilizer, and grain. It is mainly composed of a frame, a conveyor belt, rollers, rollers, a tensioning device, a transmission device, etc. Among them, the driving roller and the redirecting roller are the driving devices of the entire belt conveyor. They bear a large load and are easily damaged by fatigue and need to be replaced. However, since the rollers are installed at both ends of the endless belt, how to quickly remove the rollers from the endless belt during replacement is the key to the entire replacement and maintenance process.

[0003] The original solution for replacement was to use multiple hand hoists and other lifting equipment, and to lift the drum out of the belt loop after multiple inverted lifting. The operation was time-consuming and laborious, and repeated inverted lifting also posed a great safety hazard. In view of the above problems, certain measures need to be taken to improve them, and auxiliary replacement tools should be made to overcome the shortcomings of the traditional lifting method, which is complicated and laborious, improve maintenance efficiency, and reduce downtime.

The roller can be quickly dragged out of the endless belt when replacing the roller, and the spare roller can be conveniently delivered into the endless belt.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A belt conveyor roller online quick disassembly and assembly device comprises two trolley tracks and a trolley, a plurality of track connecting ribs are arranged between the two trolley tracks, trolley limit blocks are respectively arranged at both ends of the two trolley tracks, the trolley limit blocks are connected to the trolley tracks through limit block fixing bolts, a track fixing device is arranged below one end of the trolley track, and the trolley is arranged above the two trolley tracks and can move along the tracks.

[0007] Furthermore, the trolley includes trolley wheels and trolley axles. There are two trolley axles, and trolley wheels are respectively provided at both ends of the trolley axles. The trolley wheels are located on the trolley track. A clamping device is provided on the trolley axle. The clamping device consists of two tightening plates. The clamping plates can slide on the trolley axle. The bottom of the clamping device is connected to the trolley axle by a locking clamping bolt.

[0008] Furthermore, the top of the track fixing device is connected to the trolley track through a limit block fixing bolt, and the bottom is provided with a track fixing bolt so that the trolley track is fixed to the steel structure of the roller mounting bracket through the track fixing device.

[0009] Furthermore, a guide groove is provided at the other end of the trolley track, and the trolley limit block at this end can slide in the guide groove to limit the trolley travel.

[0010] The beneficial effects of the utility model are as follows: in the utility model, the track fixing device can firmly fix the entire track on the roller mounting bracket, and the movable trolley limit device on one side can adjust the travel range of the trolley and ensure that the trolley will not fall off the track; by adjusting the clamping device, locking the clamping bolt to the fixed position after adjusting to the appropriate position, the roller can be clamped. When replacing the roller, the roller can be quickly dragged out of the endless belt, and the spare roller can be easily sent into the endless belt. The operation is safe and fast, saving time and effort, improving maintenance efficiency, and reducing downtime. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] The utility model provides an online quick disassembly and assembly device for belt conveyor rollers, such as Figure 1-3As shown, it includes two trolley tracks 1 and a trolley, a plurality of track connecting ribs 3 are arranged between the two trolley tracks 1, trolley limit blocks 5 are respectively arranged at both ends of the two trolley tracks 1, and the trolley limit blocks 5 are connected to the trolley tracks 1 through limit block fixing bolts 9, and a track fixing device 2 is arranged below one end of the trolley track 1, and the track fixing device 2 is a vertical channel steel, and its notch faces the other end of the trolley track 1, and the top of the track fixing device 2 is connected to the trolley track 1 through the limit block fixing bolts 9, and the bottom is provided with a track fixing bolt 4, so that The track fixing device 2 fixes the trolley track 1 on the steel structure of the roller mounting bracket. A guide groove 11 is provided at the other end of the trolley track 1. The trolley limit block 5 can slide in the guide groove 11.
