[0002] Currently, if Figure 4 In the belt conveyor shown, during operation, the rollers operate continuously for a long time, especially the upper roller is severely worn and often has surface wear problems. Due to factors such as operation vibration, the roller bearings are damaged frequently, so the rollers need to be replaced.

[0003] Existing Chinese patent application number 201620113639.X discloses a belt lifting device for roller replacement, comprising a bracket fixed to a roller mounting frame, a lifting frame supported on the bracket, and a belt support plate mounted on the lifting frame. The lifting frame is capable of lifting the belt support plate with the bracket as a support base and driving the belt support plate to change height, so that the belt supported by the belt support plate is separated from the corresponding roller when replacing the roller. This belt lifting device has the following shortcomings:

[0004] 1) The bracket is fixed on a beam of a roller mounting frame, which makes it difficult to form a stable support;

[0005] 2) The belt support plate and the bracket are connected by a lifting frame, and there is no guide component. The belt support plate is prone to tilting during the process of lifting the belt and has poor stability. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a belt lifting device for roller replacement with a simple structure and good supporting stability.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The two clamping seats are respectively arranged on both sides of the telescopic support mechanism. The base is rotatably sleeved on the telescopic support mechanism, and the lifting mechanism is arranged on the base.

[0009] As a further improvement of the above technical solution:

[0010] The telescopic supporting mechanism includes a first screw, a screw sleeve and a second screw that are threadedly connected in sequence. The ends of the first screw and the second screw away from the screw sleeve are respectively connected to two clamping seats. The thread directions of the two ends of the screw sleeve are opposite, and the base is rotatably sleeved on the screw sleeve.

[0011] One end of the screw sleeve is provided with a screwing portion.

[0012] The first screw rod and the second screw rod are fixedly connected to the corresponding clamping seat.

[0032] During use, first, the two clamping seats 23 are clamped onto the two parallel beams 41 below the belt 3. Then, the two clamping seats 23 are pressed against the corresponding beams 41 by the telescopic supporting mechanism 22 to achieve a stable effect. Then, the lifting mechanism 1 lifts the belt 3 and the rollers are replaced. Because the base assembly 2 of the belt lifting device for roller replacement is firmly fixed to the two parallel beams 41 below the belt 3, it not only has a simple structure but also has good support stability.

[0033] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the telescopic support mechanism 22 includes a first screw rod 221, a screw sleeve 222, and a second screw rod 223 that are threadedly connected in sequence. The ends of the first screw rod 221 and the second screw rod 223 away from the screw sleeve 222 are respectively connected to the two holders 23. The threads at the two ends of the screw sleeve 222 are in opposite directions. The base 21 is rotatably sleeved on the screw sleeve 222. By rotating the screw sleeve 222, the telescopic support mechanism 22 can be telescopically moved to tighten the holder 23 against the crossbeam 41. The structure is simple and easy to operate. On the one hand, the telescopic support mechanism 22 can adjust the interval between the two holders 23 and can adapt to the installation of crossbeams 41 with different intervals, thereby improving adaptability. On the other hand, the screw sleeve 222 is threadedly connected to the screw rod and has a self-locking effect after being tightened against the holder 23.

The lifting movement of the lifting assembly 12 drives the lifting plate 11 to lift the belt 3.

[0038] Furthermore, in this embodiment, a telescopic guide assembly 5 is provided between the lifting plate 11 and the base 21. At least two telescopic guide assemblies 5 are provided, one on each side of the lifting assembly 12. Guided by the telescopic guide assemblies 5, the lifting plate 11 is less likely to tilt during the belt lifting process, maintaining excellent stability.
