Description

Technical Field

[0001] This utility model relates to the field of roller roundness detection technology, and in particular to an outdoor heavy-duty waterproof ladder roller roundness detection device. Background Technology

[0002] Outdoor heavy-duty waterproof ladder rollers are rollers specifically designed for heavy-duty outdoor equipment, used for smooth operation on ladders or tracks. These rollers need to be waterproof, dustproof, corrosion-resistant, and vibration-resistant to withstand harsh outdoor working environments. The roundness of the rollers directly affects the operational stability of the equipment. If the rollers are not round, it may lead to unstable equipment operation and increase the risk of accidents, so roundness testing of the rollers is necessary. However, existing roller roundness testing devices typically only test the roundness of rollers of a certain size, making it inconvenient to meet the roundness testing needs of rollers of different sizes.

[0003] Therefore, a roundness testing device for outdoor heavy-duty waterproof ladder rollers has been developed to meet the testing needs of rollers of different sizes. Utility Model Content

[0004] To overcome the shortcomings of existing roller roundness testing devices, which can only test the roundness of rollers of a certain size and are not convenient to meet the roundness testing needs of rollers of different sizes, and are relatively inconvenient to use, this utility model provides an outdoor heavy-duty waterproof ladder roller roundness testing device that can test the roundness of rollers of different sizes, so as to meet the testing needs of rollers of different sizes.

[0005] The technical solution is: an outdoor heavy-duty waterproof ladder roller roundness detection device, including a support frame, a clamping component and a detection component. The support frame is equipped with the clamping component and the detection component.

[0006] Furthermore, the clamping assembly includes a motor, a screw, a rotating block, a nut, a slide, a connecting frame, a support plate, and rollers. The motor is connected to the upper rear side of the support frame, and the screw is connected to the motor output shaft. The screw is rotatably connected to the support frame. The rotating block is rotatably connected to the upper front side of the support frame, and the rotating block is connected to the screw. The nut is threadedly connected to the front of the screw, and the slide is rotatably connected to the rear side of the nut. The slide is slidably connected to the screw. Multiple connecting frames are rotatably connected to both the front and rear parts of the slide. A support plate is rotatably connected between two vertically adjacent connecting frames. The support plates are slidably connected to the rotating block, and rollers are clamped between the support plates.

[0007] Furthermore, a limiting block is provided on the front side of the screw.

[0008] Furthermore, all the support panels are curved.

[0009] Furthermore, the detection assembly includes a bidirectional lead screw, a sliding plate, and a displacement sensor. The bidirectional lead screw is rotatably connected to the lower part of the support frame, and the left and right sides of the bidirectional lead screw are threadedly connected to the sliding plate. The upper part of the sliding plate is connected to the displacement sensor, and the displacement sensor is slidably connected to the support frame.

[0010] Furthermore, a handle is provided on the right side of the two-way lead screw.

[0011] Beneficial effects: This utility model, by rotating the nut, pushes the slide cylinder to move backward, causing the connecting frame to rotate, and the spreading plate to spread outward to clamp the roller. Then, by rotating the bidirectional screw, the sliding plates move closer to each other, causing the displacement sensor to move and contact the roller surface. Finally, the motor is started, causing the screw to drive the roller to rotate. This achieves the effect of roundness detection of rollers of different sizes, so as to meet the detection needs of rollers of different sizes. Attached Figure Description

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0018] An outdoor heavy-duty waterproof ladder roller roundness testing device, such as Figures 1-4 As shown, it includes a support frame 1, a clamping assembly and a detection assembly. The support frame 1 is equipped with the clamping assembly and the detection assembly.

[0019] like Figures 1-4As shown, the clamping assembly includes a motor 2, a screw 3, a rotating block 4, a nut 5, a slide cylinder 6, a connecting frame 7, a support plate 8, and rollers 9. The motor 2 is connected to the upper rear side of the support frame 1, and the screw 3 is connected to the output shaft of the motor 2. The screw 3 is rotatably connected to the support frame 1. The rotating block 4 is rotatably connected to the upper front side of the support frame 1. The rotating block 4 is connected to the screw 3. The nut 5 is threadedly connected to the front of the screw 3. A limit block is provided on the front side of the screw 3 to limit the nut 5. The slide cylinder 6 is rotatably connected to the rear side of the nut 5. The slide cylinder 6 is slidably connected to the screw 3. Four connecting frames 7 are rotatably connected to both the front and rear parts of the slide cylinder 6. A support plate 8 is rotatably connected between two vertically adjacent connecting frames 7. The support plates 8 are all slidably connected to the rotating block 4. Rollers 9 are clamped between the support plates 8. The support plates 8 are all arc-shaped to facilitate clamping the rollers 9.

[0020] like Figures 1-3 As shown, the detection assembly includes a bidirectional lead screw 10, a sliding plate 11, and a displacement sensor 12. The bidirectional lead screw 10 is rotatably connected to the lower part of the support frame 1. A handle is provided on the right side of the bidirectional lead screw 10 for easy gripping. The left and right sides of the bidirectional lead screw 10 are threadedly connected to the sliding plate 11. The upper part of the sliding plate 11 is connected to the displacement sensor 12. The displacement sensor 12 is slidably connected to the support frame 1.

[0021] When using this utility model, first place the support frame 1 in the roundness detection area of ​​the outdoor heavy-duty waterproof ladder roller 9, then place the roller 9 outside the support plate 8, then rotate the nut 5 so that the nut 5 moves backward on the screw 3, pushing the slide cylinder 6 to move backward, causing the connecting frame 7 to rotate, and the support plate 8 to spread outward along the rotating block 4 to clamp the roller 9. Then rotate the double-acting screw 10 so that the sliding plates 11 move closer to each other, driving the displacement sensor 12 to move closer to each other until the displacement sensor 12 contacts the surface of the roller 9. Then start the motor 2 so that the screw 3 rotates and drives the roller 9 to rotate, so that the displacement sensor 12 can detect the roundness of the roller 9, thereby enabling the roundness detection of rollers 9 of different sizes to meet the detection requirements of rollers 9 of different sizes. When the displacement sensor 12 detects a change in the displacement between itself and the roller 9, it indicates that the roundness of the roller 9 is insufficient.

[0022] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
