Description

TECHNICAL FIELD

[0002] The roller is a key component of the belt conveyor, mainly serving to support the belt and the material, reduce the running resistance, and ensure the stable operation of the belt. However, the roller will be damaged, the roller body will be worn, and the rotation will be stuck due to the impact of the material, friction, and environmental influence. If it is not replaced, it will easily cause the belt to deviate and tear, affecting the conveying efficiency, so it needs to be replaced regularly.

[0003] Currently, in order to facilitate the replacement of the roller, the belt is generally lifted and supported at the roller to be replaced to avoid the belt pressing on the roller and affecting the replacement of the roller. For example, the patent with the publication number CN115401438B discloses a belt conveyor roller replacement device. When the replacement device is used, the two sides of the belt are clamped, and then the belt is jacked up. However, due to the limited area of the clamping point, the belt is unevenly stressed, and it is easy to fall off due to local stress concentration during the lifting process, which brings safety hazards. On the other hand, for the trough conveyor, the clamping of the two sides cannot effectively support the middle part of the belt, causing the middle part of the belt to hang down, which cannot completely release the installation space of the roller, greatly affecting the replacement efficiency and operation convenience of the roller.

[0037] The operation principle of the present application is described as follows: the support frame 1 is fixed horizontally on the supports on both sides of the belt conveyor and is fixed (locked by bolts, etc.), and the support frame 1 is located on the side of the carrier roller to be replaced, then the two inclined support plates 3 are rotated towards each other to fit the inclined surfaces on both sides of the grooved belt, then the side support plates 41 on the side walls of the two inclined support plates 3 are rotated open and are clamped on the outside of the cylinder 44 by the arc-shaped clamping strips 42, the cylinder 44 and the arc-shaped clamping strips 42 stably support the inclined support plates 3, then the microcontroller 84 is started, which controls the driving motor 82 to work, the driving motor 82 drives the screw rod assembly 52 to rotate through the bevel gear assembly 83 (the bevel gear assembly 83 includes a driving bevel gear installed on the driving end of the driving motor 82 and a driven bevel gear installed on the end of the screw rod of the screw rod assembly 52, the driving bevel gear rotates to drive the driven bevel gear to rotate the screw rod of the screw rod assembly 52), when the screw rod assembly 52 rotates, the two movable tables 53 are synchronously moved towards the fixed table 51 through the screw rod nut, at this time, due to the hinged action of the movable support plate 55 and the fixed support plate 54, the bottom of the movable support plate 55 moves towards the fixed table 51, the top of the movable support plate 55 and the fixed support plate 54 starts to rotate upwards, the T-shaped sliding block 66 of the movable lifting plate 61 slides in the groove 67, and the height of the movable lifting plate 61 rises, thereby pushing the lifting plate 2 to move upwards, the lifting plate 2 synchronously moves upwards with the inclined support plate 3, thereby lifting the grooved belt, temporarily supporting the belt, and making it away from the carrier roller to be replaced, avoiding affecting the replacement of the carrier roller, without loosening the belt tensioning device or disassembling the belt joint, significantly shortening the maintenance time, and one person can operate, greatly reducing the physical load and safety hazards of traditional lever prying operation;

[0038] During the lifting of the belt, the inclined support plate 3 and the lifting plate 2 temporarily bear the support force of the belt, so the force of the belt generates pressure on the inclined support plate 3 and the lifting plate 2, the lifting plate 2 exerts pressure on the pressure sensor 62 through the movable lifting plate 61, when the pressure detected by the pressure sensors 62 at both fixed lifting plates 56 reaches a threshold value (the threshold value is set based on the material, size, etc. of the belt), the two pressure sensors 62 feed back electrical signals to the microcontroller 84, which immediately controls the driving motor 82 to stop working, avoiding over-lifting of the belt, which causes the belt to be stretched too much, thereby maximizing the lifting height of the belt while avoiding damage to the belt;

[0039] When the driving motor 82 starts, the microcontroller 84 synchronously activates the encoder 85, which is based on the incremental photoelectric encoding principle and converts each rotation of the driving end of the driving motor 82 into a pulse signal through the light-transmitting and non-light-transmitting grids on the code disc. The driving motor 82 drives the lifting plate 2 to rise through the driving screw assembly 52, so there is a fixed proportional relationship between the number of rotations recorded by the encoder 85 and the lifting height of the belt. As the belt is subjected to the weight of the material for a long time, the friction and stretching, the slack gradually increases. If the threshold pressure applied to the pressure sensor 62 is reached and the idler roller is separated, the lifting height required by the belt will be higher, and the number of pulses fed back by the encoder 85 will also exceed the standard value range (under normal working conditions of the new belt, the belt is lifted to the height of the electrical signal fed back by the pressure sensor 62, and the number of pulses recorded by the encoder 85 is the standard reference value). After receiving the electrical signal fed back by the pressure sensor 62, the microcontroller 84 compares the number of electrical signals fed back by the current encoder 85 with the standard reference value. When the difference between the two exceeds the preset threshold value (generally, when the difference exceeds 10%, it means that the working condition of the current belt is not good and needs to be adjusted in time), the microcontroller 84 triggers a voice prompt to remind the worker that the belt has been excessively slack and needs to be adjusted in time or replaced to prevent the abnormal belt from affecting the idler roller replacement operation and the normal operation of the equipment.

[0040] After the microcontroller 84 receives the electrical signal fed back by the pressure sensor 62, the microcontroller 84 will issue a voice prompt to remind the worker that the idler roller can be disassembled. At this time, the worker can control the horizontal electric push rod 91 and the vertical electric push rod 93 to work through the microcontroller 84. The horizontal electric push rod 91 can adjust the horizontal position of the two semicircular supporting plates 73, and the vertical electric push rod 93 can adjust the vertical position of the two semicircular supporting plates 73, so that the semicircular supporting plate 73 close to one side of the side plate 72 is first sleeved on one side of the idler roller, and then the other semicircular supporting plate 73 is rotated to close and sleeve the idler roller on the outside. Then the two semicircular supporting plates 73 are locked and fixed by the locking assembly 74. At this time, the bolts for fixing the idler roller can be removed. Since the idler roller is fixed by the two semicircular supporting plates 73, and the two semicircular supporting plates 73 are supported by the side plate 72, the movable frame 71, the horizontal electric push rod 91, the vertical electric push rod 93 and other components, even if the bolts of the idler roller are completely removed, the idler roller will not fall off, and personnel do not need to lift the idler roller. After the bolts of the idler roller are completely removed, the worker can pull the idler roller out from the inside of the mounting frame by moving the horizontal electric push rod 91 back through the microcontroller 84, so as to avoid the influence of the mounting frame on the removal of the idler roller. Then the locking assembly 74 is loosened, and the idler roller is removed from the two semicircular supporting plates 73.

[0041] Since the set of rollers of the trough conveyer generally has three, including a horizontal roller and two inclined rollers, before the inclined rollers are disassembled, the angle of the two semicircular supporting plates 73 can be rotated through the installation shaft 101 to match the angle of the inclined rollers, after the angle adjustment is completed, the locking cover 103 is screwed, the installation shaft 101 can be locked and fixed through the extrusion of the anti-skid disc 102 by the locking cover 103, then the inclined rollers can be disassembled;

[0042] After the rollers are disassembled, the new rollers are installed on the semicircular supporting plates 73, and through the work of the horizontal electric push rod 91 and the vertical electric push rod 93, the new rollers can be moved into the roller mounting frame, so that the rollers can be installed.

[0043] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
