Description

Technical Field

[0001] This utility model belongs to the technical field of roller gap adjustment indicator device for roller crusher, and particularly relates to a roller gap adjustment indicator device to prevent loosening. Background Technology

[0002] Double roll crushers are commonly used in steel plants for crushing materials. When adjusting the particle size of a double roll crusher, it is usually necessary to adjust the adjusting nuts on both sides separately. Due to the lack of a unified indicating reference, operators find it difficult to ensure that the adjustment amount of the nuts on both sides is consistent, resulting in uneven gap between the rolls and affecting the accuracy of sample particle size. Furthermore, during long-term operation, the adjusting nuts are prone to loosening due to vibration, causing gap changes and affecting crushing efficiency and equipment stability. Current technology lacks effective gap indication and anti-loosening structures, making it impossible to monitor and maintain the adjusted gap state in real time, resulting in problems such as inconvenient operation, low precision, and poor reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a non-loosening roller gap adjustment indicator to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A non-loosening roller gap adjustment indicator includes a frame, an adjusting screw mounted on the frame, an adjusting nut threaded onto the adjusting screw, a scale plate fixed on the frame, a number of scale lines engraved on the scale plate, the screw passing through the scale plate, an indicator plate bolted to the scale plate, a pointer on the indicator plate, and an adjusting nut passing through the indicator plate.

[0005] Furthermore, the dial is circular, with a circular hole in the center. The diameter of the circular hole is larger than the outer diameter of the adjusting screw. The adjusting screw passes through the circular hole and penetrates the dial. The dial extends outward from the machine frame on both sides. Two arc-shaped holes are symmetrically opened on both sides of the dial, located on the two sides of the dial extending out of the machine frame.

[0006] Furthermore, the scale lines are arranged in a circular array on the scale with the central axis of the scale as the axis.

[0007] Furthermore, the center of the arc-shaped hole coincides with the center of the dial, the central angle corresponding to the arc-shaped hole is greater than 60 degrees, and the two ends of the arc-shaped hole are circular.

[0008] Furthermore, a hexagonal hole is provided in the center of the indicator dial. The shape of the hexagonal hole matches the outer contour of the adjusting nut, and the adjusting nut passes through the hexagonal hole through the indicator dial.

[0009] Furthermore, both ends of the indicator are equipped with fixing plates, which extend to two arc-shaped holes respectively. Bolt pairs that pass through the fixing plates and arc-shaped holes are bolted to the fixing plates. The indicator is connected to the scale plate through the fixing plates, arc-shaped holes, and bolt pairs.

[0010] Furthermore, the pointer is perpendicular to the fixed plate, with one end of the pointer being a sharp point that points towards the scale line.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting up a scale and pointer structure, can intuitively and accurately display the adjustment amount of the roller gap, ensuring that the adjusting nuts on both sides are adjusted synchronously, thereby improving the particle size control accuracy.

[0012] 2. The indicator and adjusting nut are fitted with hexagonal holes, and the indicator and scale are bolted together to prevent the adjusting nut from loosening due to vibration during operation, thereby improving the stability of equipment operation.

[0013] 3. The adjustment amount of the gap is visualized by the interaction between the pointer and the scale, making it easy for operators to observe and record. 4. Mark the pointer position on the indicator panel with a marker pen. This will allow you to detect the offset of the adjusting nut in time when the bolt assembly becomes loose, thus providing an early warning of loosening. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0019] like Figure 1-3 As shown, an anti-loosening roller gap adjustment indicator device includes a frame 1, which serves as the mounting frame for a roller crusher. Since no structural changes have been made to other parts of the frame 1, Figure 1Only the frame 1 and the part relevant to this utility model are shown in the diagram. An adjusting screw 2 is mounted on the frame 1, and an adjusting nut 2 is threaded onto the adjusting screw 2. The adjusting screw 2 and adjusting nut 2 are devices used in the double-roll crusher to adjust the gap between the double-roll crushers. Each crushing roll has one adjusting screw 2 and one adjusting nut 2. The gap between the double-roll crushers is adjusted by turning the two adjusting nuts 2. A scale 4 is fixed to the frame 1. The scale 4 has several graduation lines 5. The screw passes through the scale 4, and an indicator 6 is bolted to the scale 4. The indicator 6 has a pointer 7, and the adjusting nut 2 passes through the indicator 6. The adjustment amount of the gap can be visualized by the interaction between the pointer 7 and the graduation lines 5.

[0020] The dial 4 is circular, and a circular hole 8 is provided in the center of the dial 4. The diameter of the circular hole 8 is larger than the outer diameter of the adjusting screw 2. The adjusting screw 2 passes through the circular hole 8 and passes through the dial 4. The dial 4 protrudes out of the outer side of the frame 1 on both sides. The dial 4 is symmetrically provided with arc-shaped holes 9 on both sides. The two arc-shaped holes 9 are located on the two sides of the dial 4 protruding out of the frame 1 respectively.

[0021] The scale lines 5 are arranged in a circular array on the scale 4 with the central axis of the scale 4 as the axis.

[0022] The center of the arc-shaped hole 9 coincides with the center of the dial 4. The central angle corresponding to the arc-shaped hole 9 is greater than 60 degrees. The fixing plate 11 on the indicator 6 may not be perfectly aligned with the area of ​​the arc-shaped hole 9. The central angle greater than 60 degrees can be corrected by removing the indicator 6, rotating it, and then re-engaging the adjusting nut 2 to align the fixing plate 11 with the area of ​​the arc-shaped hole 9. The two ends of the arc-shaped hole 9 are round.

[0023] A hexagonal hole 10 is provided in the center of the indicator dial 6. The shape of the hexagonal hole 10 matches the outer contour of the adjusting nut 2. The adjusting nut 2 passes through the hexagonal hole 10 and passes through the indicator dial 6. The indicator dial 6 can rotate with the adjusting nut 2 and is engaged with the adjusting nut 2 through the hexagonal hole 10.

[0024] The indicator dial 6 has fixing plates 11 at both ends, and the two fixing plates 11 extend to two arc-shaped holes 9 respectively. Bolt pairs 12 that pass through the fixing plates 11 and the arc-shaped holes 9 are bolted to the fixing plates 11. The indicator dial 6 is bolted to the scale dial 4 through the fixing plates 11, the arc-shaped holes 9, and the bolt pairs 12. After the indicator dial 6 is fixed to the scale dial 4, it can prevent the adjusting nut 2 from loosening.

[0025] The pointer 7 is perpendicular to the fixed plate 11. One end of the pointer 7 is pointed, and the pointed end points to the scale line 5.

[0026] The working principle of this utility model is as follows: During the adjustment of the roller gap, the operator rotates the adjusting nut 2, which moves the adjusting screw 2, thereby changing the gap between the rollers. When the adjusting nut 2 rotates, it drives the indicator disk 6 to rotate synchronously through the hexagonal hole 10, and the pointer 7 indicates the corresponding rotation angle on the scale disk 4 via the scale line 5. There is a preset correspondence between the angle value corresponding to the scale line 5 on the scale disk 4 and the adjustment amount of the roller gap. This correspondence can be determined through calibration, allowing the operator to achieve equal and synchronous adjustment of the gap on both sides by controlling the adjustment nuts 2 to rotate by the same angle. This ensures that the adjustment amount of the adjustment nuts 2 on both sides is consistent, guaranteeing a uniform roller gap. After the gap adjustment is completed, the indicator disk 6 is fixed to the scale disk 4 using bolts 12 (if the ends of the fixing plate 11 deviate from the arc-shaped hole 9, the indicator disk 6 can be removed, the angle of the fixing plate 11 adjusted, and then it can be snapped onto the adjusting nut 2), thus preventing the adjusting nut 2 from loosening. Mark the scale line 5 that the pointer 7 is pointing to on the indicator dial 6 with a marker. If there is a large vibration, the bolt pair 12 will also become loose, and the adjusting nut 2 will become loose. The position of the pointer 7 will shift, thus making the loosening of the adjusting nut 2 visible. The operator can notice it in time and tighten it again.

[0027] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
