Description

Technical Field

[0001] The utility model belongs to the technical field of redirecting rollers, and particularly relates to an all-round adjustment device for a belt redirecting roller. Background Technique

[0002] The reasons for belt deviation are as follows: materials adhere to the belt or roller, idlers and rollers are damaged, the belt deviates due to external force, the belt corridor deforms due to thermal expansion and contraction, and the equipment is not aligned during installation, etc. Among them, the first three can be adjusted through rectification and maintenance in a short time. The latter two are difficult to adjust, time-consuming and laborious. Especially for the belt deviation of the long material transportation form, it can only be slightly adjusted by adjusting the idlers and the problem cannot be completely solved. Long-term deviation operation is likely to cause equipment failures such as slipping and tearing.

[0003] The main belt deviation adjustment methods are to adjust the idlers and the form of the retaining rollers. The adjustable range of this technology is small, and when the material is too heavy, it will affect the adjustment effect and cannot fundamentally solve the problem, with too many limitations. When the belt travel exceeds 300 meters, the belt deviation caused by the deformation of the belt corridor due to thermal expansion and contraction under the influence of the environment cannot be cured, and can only be slightly adjusted by adjusting the idlers. The adjustment method for the belt deviation of a short stroke is to adjust through the redirecting roller.

[0004] At present, the adjustment of the redirecting roller is rather troublesome. Even multiple people are required to cooperate and use tools such as crowbars for adjustment, with low work efficiency and affecting the production rhythm. Summary of the Invention

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model.

[0021] As Figure 1-2As shown in the figure, an all-round adjustment device for a belt redirecting roller includes a floor foundation plate 1, on which a horizontal adjustment lead screw 2 is installed. Two sliding blocks 3 are threadedly connected to the horizontal adjustment lead screw 2. A channel steel 4 is fixedly connected to the two sliding blocks 3. A support cover 5 is welded to the channel steel 4. The support cover 5 is bolted to the floor foundation plate 1. A redirecting roller bearing seat 6 is bolted to the support cover 5. A number of vertical adjustment bolts 7 are threadedly connected to the support cover 5, and the tails of the vertical adjustment bolts 7 abut against the bottom of the redirecting roller bearing seat 6.

[0022] Both ends of the horizontal adjustment lead screw 2 are connected to mounting blocks 8 by bearings. The mounting blocks 8 are fixedly connected to the floor foundation plate 1. The horizontal adjustment lead screw 2 is installed on the floor foundation plate 1 through the mounting blocks 8. After the horizontal adjustment lead screw 2 is connected to the mounting blocks 8 by bearings, it can rotate on the mounting blocks 8, thereby driving the threaded sliding blocks 3 to displace, so as to carry out adjustment in the horizontal direction.

[0023] A number of horizontal adjustment holes 9 are opened on the floor foundation plate 1. The horizontal adjustment holes 9 are strip-shaped. After the position of the support cover 5 changes, its fixed position on the floor foundation plate 1 also changes. Therefore, the horizontal adjustment holes 9 are provided to adapt to the change of the position of the support cover 5. At the same time, multiple fixing bolts can also be used and arranged in the horizontal adjustment holes 9 to strengthen the fixing effect of the support cover 5.

[0024] The cross-section of the support cover 5 is in a shape of a capital "J". The support cover 5 is bolted through positioning bolts in the horizontal adjustment holes 9 on the floor foundation plate 1. A number of operation windows 10 are symmetrically opened on both sides of the support cover 5. The operation windows 10 are used to facilitate inserting a wrench into the inside of the support cover 5 for operation.

[0025] The cross-section of the channel steel 4 is in a U shape. The U-shaped channel steel 4 is buckled downward with its opening and bolted to the two sliding blocks 3.

[0026] There are four vertical adjustment bolts 7. The four vertical adjustment bolts 7 are respectively located at the four corners of the bottom of the redirecting roller bearing seat 6. Fixing nuts 11 are threadedly connected to the vertical adjustment bolts 7. The redirecting roller bearing seat 6 will be deflected, so that the redirecting roller bearing seat 6 is not perpendicular to the redirecting roller, which will cause wear at the connection between the redirecting roller bearing seat 6 and the redirecting roller. By adjusting the heights of the four corners of the bottom of the redirecting roller bearing seat 6, it can be corrected.

[0027] The working principle of the present utility model is:

[0028] When horizontal adjustment is required, loosen the bolt connection between the support cover 5 and the floor foundation plate 1, and use tools such as a wrench to rotate the top of the horizontal adjustment screw rod 2. The sliding block 3 threaded to the horizontal adjustment screw rod 2 will displace as the horizontal adjustment screw rod 2 rotates, thereby driving the deviation rectifying roller bearing seat 6 to displace. After the adjustment is in place, bolt the support cover 5 into the horizontal adjustment hole 9 of the floor foundation plate 1, thus completing the horizontal adjustment of the deviation rectifying roller bearing seat 6.

[0029] When the deviation rectifying roller bearing seat 6 is skewed and vertical adjustment is required, loosen the bolt connection between the deviation rectifying roller bearing seat 6 and the support cover 5. According to the skewing situation of the deviation rectifying roller bearing seat 6, loosen the fixing nut 11 on the vertical adjustment bolt 7 that needs to be adjusted, and turn the vertical adjustment bolt 7 to make it push up or drop down, thereby adjusting the height of a certain corner of the deviation rectifying roller bearing seat 6. After the adjustment is good, tighten the fixing nut 11 and tighten the bolt connection between the deviation rectifying roller bearing seat 6 and the support cover 5, thus completing the vertical adjustment.

Without departing from the design concept of the present invention, various variations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention.
