[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] Please refer to the attached Figure 1 and Figure 2 , combined with a specific embodiment, it is described as follows: a laterally movable conveyor roller frame described in the present invention includes a roller 6 and a roller bracket for supporting the roller 6; specifically, the specific structure of the roller 6 and the roller bracket can refer to the existing belt conveyor.

[0024] The bearing seats 7 at both ends of the roller 6 are connected to the support platform 2, which is a rectangular plate body. Sliding wheels 3 are arranged on the bottom side of the support platform 2; specifically, two sliding wheels 3 are grouped together, and the two sliding wheels 3 are symmetrically arranged on the bottom side of the support platform 2.

[0025] The roller bracket is provided with a track platform 4 capable of supporting the roller 6, and the track platform 4 is provided with a slide rail 1 corresponding to the sliding wheel 3. The slide rail 1 is a triangular track, and the sliding wheel 3 is arranged on the slide rail 1, so that a sliding connection structure can be formed between the roller 6 and the roller bracket.

[0026] The support platform 2 and the track platform 4 are connected to each other through the positioning arm 5, the top end of the positioning arm 5 is detachably connected to the support platform 2, and the bottom end of the positioning arm 5 is detachably connected to the track platform 4; specifically, two positioning arms 5 form a group, and the two positioning arms 5 are symmetrically arranged on both sides of the track platform 4; the positioning arm 5 is detachably connected to the support platform 2 and the track platform 4 respectively by bolt connection.

[0027] The use principle of the present invention: Under normal conditions, the support platform 2 is connected to the track platform 4 as a whole through the positioning arm 5, so that the roller 6 can be fixed on the roller bracket. When the roller 6 needs to be replaced, the staff removes the positioning arm 5. At this time, the support platform 2 is separated from the track platform 4, and the support platform 2 and the sliding wheel 3 are equivalent to forming a trolley structure. The staff only needs to drag the trolley, and the roller 6 can be moved to the side of the roller bracket with the trolley, that is, lateral movement. After the movement is completed, the staff performs the operation, and after replacing the roller 6, the unloading car can be dragged in the reverse direction to return to the original position, and the positioning arm 5 can be reconnected. It can be seen that by using this device, the cooperation of a crane is no longer required, and the replacement can be completed on the side of the roller bracket by using a hanging hoist to lift the tape, which effectively reduces the difficulty of replacing the roller 6, thereby reducing the maintenance cost, and is suitable for promotion.

[0028] The operation method of the lateral movable conveyor roller frame comprises the following steps: S1. Remove the counterweight block in the conveyor belt tensioning device. If the belt tensioning device adopts a hydraulic tensioning device, adjust the hydraulic tensioning roller stroke of the hydraulic tensioning device to a relaxed state so that the belt is in a non-tensioned state. Then use tools to pull the belt wrapped on the roller to a safe position to separate the belt from the roller, so as not to affect subsequent operations. S2. Lay two extended rails at the end of the slide rail 1, with the long rail on one side of the roller and the length of the long rail being greater than the full length of the roller. The long rail should be stable enough to bear the weight of the roller and its support platform 2; S3, releasing the connection between the support platform 2 and the positioning arm 5, so that the support platform 2 and the positioning arm 5 are in a separated state; S4. Push the support platform 2, and the support platform 2 can drive the roller 6 connected thereto to move laterally and through the slide rail to the extended track, that is, the roller 6 and the support platform 2 are separated from the original installation position by lateral movement. In this state, the staff can carry out repair, maintenance, lifting and disassembly work, and are no longer affected by the position of the original winding belt.

[0029] It can be seen that this lateral movement of the roller effectively reduces the difficulty of replacing the roller, thereby reducing maintenance costs.
