Description

Technical Field

[0001] The utility model relates to the technical field of belt deviation correction, in particular to a belt conveyor deviation correction lower roller. Background Art

[0002] The belt conveyor as a whole mainly includes a drive device and a transmission roller. The middle part is mainly composed of a belt frame, trough rollers, self-aligning rollers and parallel rollers. The belt conveyor will vibrate when it is running, and the rollers will also wear out after long-term operation. In addition, impurities adhere to the surface of the rollers or drums, the belt tension is insufficient, and the material loading is unbalanced, which will cause the belt to deviate.

[0003] When the existing belt conveyor deflection correction lower rollers are used, the mainstream lower deflection correction rollers are conical lower deflection correction rollers and hydraulic lower deflection correction rollers. Both of them drive the side uprights through the belt deviation to make the rollers tilted front and back. When passing through the same horizontal line, the belts are unevenly stressed and the belt deviation is adjusted in the opposite direction. However, the correction result is uncontrollable, the correction effect is unknown, there is uncertainty, and it is difficult to grasp data such as whether the belt is deviating, to the left or to the right, and whether the correction is completed.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a belt conveyor deflection correction lower roller comprises a deflection correction roller body 1 and two shaft support seats 12, the deflection correction roller body 1 has deep groove ball bearing bodies 3 installed at both sides through bearing seats 2, and the two deep groove ball bearing bodies 3 have shock-absorbing jackets 4 rotatably installed inside.

[0022] The same roller shaft body 5 is arranged inside the two shock-absorbing jackets 1 4, a shock-absorbing jacket 2 6 is arranged at the center of the outer ring of the roller shaft body 5, and a rubber shock-absorbing block 7 is arranged between the outer ring of the roller shaft body 5 and the inner ring of the shock-absorbing jacket 2 6, the ends of the two shock-absorbing jackets 1 4 close to each other are connected to the outer ring of the shock-absorbing jacket 2 6, and the two ends of the roller shaft body 5 are respectively installed on the opposite surfaces of the two shaft support seats 12 through movable blocks.

[0023] In this embodiment, the correcting roller body 1 is rotatably connected to the roller shaft body 5 via a deep groove ball bearing body 3, and a skeleton oil seal 8 matching the shock-absorbing sleeve 4 is installed inside the two bearing seats 2, so that the correcting roller body 1 can assist the belt in rotating, and the skeleton oil seal 8 plays a sealing role.

[0024] In this embodiment, a laser ranging sensor 13 is installed at the rear position of the outer ring of the roller shaft body 5, and the laser ranging sensor 13 does not contact the inner wall of the correction roller body 1. Through the set laser ranging sensor 13, the distance between the inner wall of the correction roller body 1 and the roller shaft body 5 can be continuously measured to observe the correction situation in real time, and it is also convenient to observe data such as whether the correction is completed.

[0025] In this embodiment, dustproof ring fixing rings 9 are provided at the front and rear ends of the interior of the deviation correcting roller body 1. Rubber dustproof rings 11 are installed at the ends of the two dustproof ring fixing rings 9 that are away from each other through throat clamps 10. The rubber dustproof rings 11 are provided to facilitate blocking dust and impurities.

[0026] In this embodiment, the rubber dust ring 11 is conical and made of soft rubber. The rubber dust ring 11 is soft so that it can be retracted to avoid being broken.

[0027] As a further solution of the utility model, the inner part of the rubber dust ring 11 and one end away from the dust ring fixing ring 9 is fitted with the outer ring of the roller shaft body 5, and the rubber dust ring 11 and the roller shaft body 5 are movably connected. The rubber dust ring 11 fits with the roller shaft body 5 to prevent most of the dust from passing through the gap. At the same time, the movably connected connection can push the rubber dust ring 11 to slide on the roller shaft body 5, which is convenient for adjustment during installation or disassembly.

[0028] It should be noted that the utility model is a belt conveyor deviation correction lower roller. When in use, firstly, the rubber damping block 7 is arranged at the center point of the roller shaft body 5, and the rubber damping block 7 has compressible and stretchable characteristics, and at the same time, the damping jacket 4 is rotatably connected to the deviation correction roller body 1 through the deep groove ball bearing body 3;

[0029] Therefore, when the belt on the deflection correction roller body 1 deviates during operation, the belt is inconsistent with the center line of the deflection correction roller body 1, which will cause the rubber damping block 7 to be unevenly stressed and deformed. When the rubber damping block 7 is deformed, the roller shaft body 5 is fixed, and the damping jacket 14 will drive the deflection correction roller body 1 to tilt under the action of pressure, and drive it to rotate relative to the roller shaft body 5 to perform conical motion. At the same time, the conical motion of the deflection correction roller body 1 is symmetrical with the center.

[0030] That is, when the belt deviates to the left, the circumferential force on the left side of the deviation-correcting roller body 1 is greater than that on the right side, causing the belt to deviate to the right and return to the right position;

[0031] It can be seen that when the belt deviates to the right, the opposite action to the above steps will be performed to correct the belt, so as to make the center line of the belt coincide with the center line of the deviation correction roller body 1, until the rubber damping block 7 is balanced again after coincidence, so as to facilitate the normal operation of the belt;

[0032] At the same time, during the operation of the belt, the distance between the inner wall of the deviation-correcting roller body 1 and the roller shaft body 5 can be continuously measured by the laser distance sensor 13. When the belt runs smoothly in the center, the distance between the two remains unchanged or fluctuates slightly within a suitable range such as 3 mm.

[0033] When the belt starts to deviate, the distance between the two presents a peak-to-valley curve. The greater the peak-to-valley difference, the more serious the deviation. The laser distance sensor 13 can be connected to the external host computer as needed, and then the electrical signal value is transmitted to the external host computer through the laser distance sensor 13, and the measurement interval of the laser distance sensor 13 is adjusted. The laser distance sensor 13 can be adjusted to measure 7-10 times per second, so as to observe the deviation correction situation in real time, realize the control of the deviation correction result, and at the same time facilitate the observation of data such as whether the deviation correction is completed.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
