In the power industry, it is mainly used for coal transportation in coal-fired power plants. In the construction and chemical industries, it is also a key equipment for achieving rapid material transportation.

[0004] At present, when conveyor rollers are repaired and replaced, workers generally use tools such as hand winches to operate. Due to the small internal space of the existing roller bracket, roller replacement is relatively complicated and difficult, with low work efficiency and high maintenance costs. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art of complicated roller replacement and low working efficiency, and to provide a lifting conveyor roller seat and an operating method thereof. The conveyor roller seat has a reasonable design, a simple structure, is easy to use, and has a lifting function. It can effectively reduce the difficulty of replacing the roller, thereby reducing maintenance costs and is suitable for promotion.

[0006] The present invention is achieved through the following technical scheme: a lifting conveyor roller seat, including a roller, bearing seats at both ends of the roller are connected to a lifting platform, and frames for support are respectively arranged at both ends of the roller; the frame is connected to the lifting platform through a telescopic mechanism, the top of the telescopic mechanism is connected to the cross beam of the frame, and the bottom end of the telescopic mechanism is detachably connected to the lifting platform; a raised seat is arranged under the lifting platform, and the telescopic mechanism can be extended to place the lifting platform on the raised seat, and the lifting platform is detachably connected to the raised seat.

[0007] A further improvement of the present invention is that the raised seat has a modular structure, and the modules are detachably connected to each other.

[0008] A further improvement of the present invention is that two telescopic mechanisms form a group, and the two telescopic mechanisms are symmetrically arranged at two ends of the lifting platform, that is, symmetrically arranged at two sides of the drum.

[0009] A further improvement of the present invention is that the telescopic mechanism is a hydraulic cylinder.

[0010] A further improvement of the present invention is that the lifting platform is a plate body with a rectangular structure, and a fork hole matching with a forklift is opened on the lifting platform.

[0011] A further improvement of the present invention is that the frame is a gantry.

[0012] The operation method of the lifting conveyor roller seat includes the following steps: S1. Remove the counterweight in the conveyor belt tensioning device to make the belt in a loose state. Then use tools to pull the belt wrapped around the roller to a safe position to separate the belt from the roller so as not to affect subsequent operations.

[0013] S2, releasing the connection between the lifting platform and the raising seat, so that the lifting platform and the raising seat are in a separated state.

[0014] S3, start the telescopic mechanism, the telescopic mechanism drives the lifting platform to drive the upper roller to move upward as a whole, so that the roller is separated from the raising seat.

[0025] Please refer to the attached Figure 1 , combined with a specific embodiment, it is explained as follows: a lifting conveyor roller seat described in the present invention includes a roller 1, bearing seats 2 at both ends of the roller 1 are connected to a lifting platform 3, and frames 5 for support are respectively provided at both ends of the roller 1; specifically, the lifting platform 3 is a rectangular plate body, and a fork hole 4 cooperating with a forklift is opened on the lifting platform 3, and the frame 5 is a gantry.

[0026] The frame 5 is connected to the lifting platform 3 through a telescopic mechanism 6, the top of the telescopic mechanism 6 is connected to the crossbeam of the frame 5, and the bottom of the telescopic mechanism 6 is detachably connected to the lifting platform 3; specifically, the telescopic mechanism 6 is a hydraulic cylinder, and two telescopic mechanisms 6 form a group. The two telescopic mechanisms 6 are symmetrically arranged at both ends of the lifting platform 3, that is, symmetrically arranged on both sides of the drum 1.

[0027] A raised seat 7 is provided under the lifting platform 3. The telescopic mechanism 6 can be extended and retracted to place the lifting platform 3 on the raised seat 7, and the lifting platform 3 and the raised seat 7 are detachably connected. Specifically, the raised seat 7 is a modular structure, and each module is detachably connected. The raised seat 7 is modular and can be combined in various ways according to different center height requirements.

[0028] Specifically, the above-mentioned detachable connections all adopt bolt connection mode.

[0029] The use principle of the present invention; Under normal conditions, the frame 5 is fixed on the ground, the raised seat 7 is directly placed on the ground, and the raised seat 7 is connected to the lifting platform 3, so that the drum 1 can be fixed on the raised seat 7. When the drum 1 needs to be repaired and replaced, the staff first removes the connection between the lifting platform 3 and the raised seat 7, and then starts the telescopic mechanism 6, which lifts the drum 1 so that the lifting platform 3 is completely separated from the raised seat 7; at this time, the staff removes the raised seat 7, that is, a space is formed under the drum 1, and then starts the telescopic mechanism 6, which lowers the drum 1 so that the lifting platform 3 is lowered to correspond to the fork of the forklift; at this time, the staff drives the forklift and inserts the fork into the fork hole 4 on the lifting platform 3, and then removes the connection between the lifting platform 3 and the telescopic mechanism 6, so that the lifting platform 3 is completely separated from the telescopic mechanism 6; in this state, the staff can drive the forklift to remove the drum 1, so that the drum 1 can be moved to a spacious space. It can be seen that the use of this device avoids the staff from replacing the drum 1 by tools such as hand winches, effectively reducing the difficulty of replacement, thereby reducing the maintenance cost.

[0030] The operation method of the lifting conveyor roller seat includes 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 stroke of the hydraulic tensioning roller 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.

[0031] S2, releasing the connection between the lifting platform 3 and the raising seat 7, so that the lifting platform 3 and the raising seat 7 are in a separated state.

[0032] S3, start the telescopic mechanism 6, which drives the lifting platform 3 to drive the roller 1 on the upper part to move upward as a whole, so that the roller 1 is separated from the raising seat 7.

[0033] S4, releasing the fixing relationship between the raising seat 7 and the base, and pulling out the raising seat 7, so as to make room for the fork arm to work.

[0034] S5. Drive the fork arm loading and unloading machine and insert its fork arm from the side to the bottom of the lifting platform 3 or into the fork hole 4.

[0035] S6. Start the telescopic mechanism 6 again, and the telescopic mechanism 6 drives the lifting platform 3 and the roller 1 on the upper part to move downward as a whole, until the lifting platform 3 falls stably on the fork arm, or reaches a suitable height that matches the fork arm loading and unloading machinery.

[0036] S7. Release the connection between the telescopic mechanism 6 and the lifting platform 3. The fork arm loading and unloading machine moves the lifting platform 3 and the roller 1 on it out laterally as a whole, so as to place them in an open space. In this state, the staff can carry out subsequent operations.

[0037] It can be seen that this operation mode effectively reduces the difficulty of replacing the roller, thereby reducing the maintenance cost.
