Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment for smelting auxiliary materials in steel plants, namely a belt anti-deviation device for a charging car. Background Art

[0002] In the prior art, in the conveying equipment for smelting auxiliary materials in steel plants, since the charging car for steelmaking moves to distribute materials, the running height and the suspended length of the belt constantly change. At the same time, the change of environmental temperature difference, heavy load operation and complex production conditions cause the problem of belt deviation to be particularly prominent in the charging car for steelmaking. This not only reduces production efficiency, but also may cause equipment damage and even lead to safety accidents, posing a serious threat to production safety and economic benefits. Content of the Utility Model

[0003] The purpose of the utility model is to provide a belt anti-deviation device for a charging car with reasonable structure and safe use in view of the above deficiencies.

[0004] The technical solution of the utility model is: a belt anti-deviation device for a charging car, including a retaining roller, characterized in that the lower end of the retaining roller is connected with a retaining roller rod, the retaining roller rod is movably connected with a support sleeve, and the retaining roller rod is fixedly connected through a positioning set screw on the side surface of the support sleeve; an internal gear disk and an external gear disk that are meshed with each other are fixed on the outer side surface of the support sleeve, the rear end surface of the external gear disk is fixedly connected with a support column, a bolt passes through the central hole of the external gear disk and is fixedly connected with the center of the internal gear disk, and a nut is provided on the bolt to fasten and connect the external gear disk and the internal gear disk, and the support column is fixedly connected with a belt mounting bracket.

[0005] The belt anti-deviation device for the charging car is symmetrically installed at multiple points on both sides of the belt.

[0006] The advantages of the utility model are: 1. Two or more belt retaining rollers are arranged on both sides of the belt. The retaining rollers have a certain inward inclination angle, which generates an inward and downward binding force on the belt, destroys the resonance frequency of the belt, and prevents the belt from deviating. The height of the belt retaining roller can be adjusted through the positioning set screw, and the inclination angle of the retaining roller can be adjusted by rotating and connecting the internal gear disk and the external gear disk. 2. The device has the characteristics of simple structure, fast repair, easy maintenance and strong adaptability, solves the problems of belt deviation and resonance material dropping caused by the change of height and suspended length of the belt for steelmaking enterprises, improves the running stability of the charging car, ensures the continuity and safety of steelmaking production, and reduces the maintenance cost at the same time.

[0007] The following will further describe in detail the embodiments of the utility model with reference to the drawings. Description of the Drawings

[0012] See Figure 1 -4, the names of the parts are as follows: retaining roller 1, retaining roller rod 2, support sleeve 3, positioning set screw 4, internal gear disk 5, external gear disk 6, support column 7, belt mounting bracket 8, bolt 9, belt 10, cloth truck 11, moved cloth truck 12, position after the belt is lifted 13, belt idler 14, nut 15.

[0013] See Figure 1 -4, the anti-deviation device for the cloth truck belt includes a retaining roller 1. The lower end of the retaining roller 1 is connected to the retaining roller rod 2, and the retaining roller rod 2 is movably connected to the support sleeve 3. The retaining roller rod 2 is fixedly connected through the positioning set screw 4 (a bolt) on the side of the support sleeve 3. Loosen the positioning set screw 4, and the retaining roller rod 2 can slide up and down in the support sleeve 3, and the height of the belt retaining roller 1 can be adjusted. The outer side of the support sleeve 3 is fixedly provided with an internal gear disk 5 and an external gear disk 6 that are engaged with each other to prevent the position of the internal gear disk 5 and the external gear disk 6 from shifting after being fixed. The rear end face of the external gear disk 6 is fixedly connected to the support column 7. The bolt 9 passes through the central hole of the external gear disk 6 and is fixedly connected to the center of the internal gear disk 5. The bolt 9 is provided with a nut 15 to fasten and connect the external gear disk 6 and the internal gear disk 5. The bolt 9 and the internal gear disk 5 are integrated. The bolt 9 horizontally penetrates the external gear disk 6. The external gear disk 6 is a fixed part, and the internal gear disk 5 is a movable part. Loosen the nut 15, separate the internal gear disk 5 and the external gear disk 6 relatively, rotate the internal gear disk 5, and then the internal gear disk 5 and the external gear disk 6 are aligned again. At this time, the retaining roller 1 rotates by an angle along with the internal gear disk 5, realizing the angle adjustment of the retaining roller 1. The support column 7 is fixedly connected to the belt mounting bracket 8 by welding. There is a bolt hole in the middle of the external gear disk 6. The bolt 9 passes through the bolt hole and is fixedly connected to the internal gear disk 5. The outer end of the bolt 9 is fastened by a nut 15. This device is symmetrically installed at multiple points on both sides of the belt 10 (see Figure 4 )

[0014] See Figure 3 、 4, Working principle: Before and after the movement of the cloth truck 11, the height of the cloth truck belt 10 at the position of the belt roller 1 changes continuously. When the belt 10 is at a high position, due to the certain inward inclination angle of the two belt rollers 1, an inward and downward binding force is generated on the belt 10, which destroys the resonance frequency of the belt 10 and prevents the belt 10 from running off track. The height of the belt roller 1 can be adjusted through the positioning set screw 4. By separating, rotating, and then fitting and fixing the internal gear disk 5 and the external gear disk 6, the roller 1 is driven to rotate, and the inclination angle of the belt roller 1 can be adjusted. By adjusting the height and inclination angle of the roller 1 through this device, the running-off track and resonance of the belt are restricted.

[0015] The above description is only the specific implementation manner of the present utility model, and various examples do not constitute a limitation to the substantive content of the present utility model.
