Description

Technical Field

[0001] This utility model relates to the field of steel drum conveying equipment, specifically a steel drum conveying device with flexible track adjustment. Background Technology

[0002] Steel drum conveying equipment plays a crucial role in the production, processing, and transportation of steel drums, improving production efficiency and reducing labor costs.

[0003] Steel drum conveying equipment has many applications. For example, steel drums produced on the first floor of a factory need to be placed in a warehouse on the second floor, or steel drums in a warehouse on the second floor need to be transported to the factory on the first floor for further processing. Both of these situations require steel drum conveying equipment to work in conjunction with a lifting platform. The conveying equipment transports the steel drums to the lifting platform, which then moves the drums up and down the stairs. Because the conveying equipment needs to connect with the lifting platform, the steel drums should be conveyed vertically. If the conveying is horizontal, an arc-shaped base matching the diameter of the steel drum must be placed on the lifting platform to prevent the drum from rolling.

[0004] In addition, since steel drums come in different models, each with a different diameter and height, steel drum conveying equipment that can transport different models of steel drums can save on equipment costs.

[0005] Chinese invention patent CN108657727A discloses a flexible horizontal steel drum conveying device. It consists of a pair of radial support conveying mechanisms on a workbench for conveying steel drums, and a radial adjustment mechanism within each radial support conveying mechanism to adapt to the diameter of the steel drums. Multiple axial adjustment mechanisms for adjusting the axial spacing between adjacent pairs of radial support conveying mechanisms are also installed. This invention patent utilizes the radial support conveying mechanism to convey steel drums on a straight track. The arrangement of the radial adjustment mechanisms can adapt to steel drums of different diameters, and the arrangement of the axial adjustment mechanisms can adapt to steel drums of different lengths. However, this conveying device is a horizontal steel drum conveying method, which is inconvenient for use in conjunction with a lifting platform. Utility Model Content

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] See Figure 1-5 The present invention provides a flexible track-changing steel drum conveying device, comprising a conveyor belt 1, a steel drum blocking and release assembly 2, a flexible track-changing assembly 4, a rangefinder 5, a steel wire rope 6, a first single-position blocking cylinder 8, and a second single-position blocking cylinder 9. The rangefinder 5 is located at the front of the conveyor belt 1 and is used to measure the diameter of the steel drum 3 conveyed on the conveyor belt 1. The flexible track-changing assembly 4 is located below the conveyor belt 1 and is used to adapt to the diameter of the steel drum 3 measured by the rangefinder 5, allowing the steel drum 3 to advance along the center of the conveyor belt 1. The end of the conveyor belt 1 is connected to an elevator 7. The first single-position blocking cylinder 8, the second single-position blocking cylinder 9, and the steel drum blocking and release assembly 2 are located at the rear of the conveyor belt 1 and are respectively used to block the forward conveying of the first steel drum, the second steel drum, and the remaining steel drums located at the rear of the conveyor belt.

[0028] Specifically, the conveyor belt 1 is equipped with several rotatable conveyor rollers 11, with gaps between adjacent conveyor rollers 11. The conveyor rollers 11 are driven to roll by a servo motor, so as to transport the steel drum 3 from the front end to the end of the conveyor belt 1. Figure 2 The direction indicated by the arrow in the middle is the conveying direction of conveyor belt 1, denoted as the X direction.

[0029] At least two sets of the flexible track-changing assembly 4 are provided, located at the rear of the conveyor belt 1 and the rear of the rangefinder 5, respectively. If the length of the conveyor belt 1 is long, the flexible track-changing assembly 4 needs to be added as appropriate.

[0030] The flexible track-changing assembly 4 includes a motor 41, a forward and reverse threaded rod 42, an adjusting plate 43, a guide rail 44, a base 45, a fixed pulley 46, and a column 47. The base 45 is fixed to the ground below the conveyor belt 1. The motor 41 is mounted on the base 45. The base 45 has a guide rail 44 and two bearing seats along the Y direction. Each guide rail 44 has at least two second sliders 50. The positive and negative threaded rods 42 are sleeved in the bearing seats on the base 45 and are connected to the output end of the motor 41. The positive threaded rods 42 have a positive threaded rod seat 48 and a negative threaded rod seat 49. Two adjusting plates 43 are provided, located on both sides below the conveyor belt. The two adjusting plates 43 are fixed on different second sliders 50 and are fixedly connected to the positive threaded rod seat 48 and the negative threaded rod seat 49, respectively. The adjusting plate 43 has a column 47 that passes upward through the gap of the conveyor roller 11. The fixed pulleys 46 are symmetrically arranged on both sides above the conveyor belt 1 and mounted on the column 47. That is, the fixed pulleys 46 on both sides of the conveyor belt 1 are equidistant from the central axis of the conveyor belt 1. The Y-direction positions of the fixed pulleys 46 on both sides of each flexible track-changing assembly 4 are kept the same. Two steel wire ropes 6 are provided, which are respectively wound around the fixed pulleys 46 in each flexible track-changing assembly 4 on both sides of the conveyor belt 1, so that the steel wire ropes 6 are parallel to the axis of the conveyor belt 1, and the distance between the steel wire ropes 6 on both sides and the axis of the conveyor belt 1 is kept equal.

[0031] The synchronous rotation of the motors 41 in each flexible track-changing assembly 4 drives the forward and reverse threaded rods 42 to rotate synchronously in the forward or reverse direction. This causes the forward threaded rod seats 48 and reverse threaded rod seats 49 to move the adjusting plates 43 on both sides closer or further apart, thereby synchronously adjusting the distance between the fixed pulleys 46 on both sides above the transmission belt 1. Ultimately, the distance between the steel wire ropes 6 on both sides matches the diameter of the steel drum measured by the rangefinder 5, thus achieving flexible track changing. The conveying device of this utility model is suitable for conveying small steel drums with a diameter of 260~500mm.

[0032] One end of the wire rope 6 is fixed to the ground, and the other end is suspended by a counterweight 10, which can ensure that the wire rope 6 remains taut and straight during the flexible track change process.

[0033] The flexible track-changing assembly 4 enables the steel wire ropes 6 on both sides to move symmetrically and parallel along the axis of the conveyor belt 1, so that the steel drum 3 is limited by the steel wire ropes 6 and then transported along the central axis of the conveyor belt 1.

[0034] The steel drum blocking and releasing assembly 2 includes a bracket 21, a first cylinder 22, a second cylinder 23, a mounting plate 24, a slide rail 25, a first stop lever 26, a connecting rod 28, a second stop lever 29, a roller 30, and a vertical stop lever 31. The bracket 21 is mounted on the conveyor belt 1, and its height is higher than the height of the steel drum 3. Slide rails 25 are provided on both sides of the top of the bracket 21 along the X direction, and first sliders 27 are provided on the slide rails 25. Both ends of the mounting plate 24 are fixed to the first sliders 27. The second cylinder 23 is mounted on the top of the bracket 21, and its piston rod is connected to the mounting plate 24. The first stop lever 26 and the second stop lever 29 are hinged below the mounting plate 24, and both ends of the connecting rod 28 are respectively hinged to the first stop lever 26 and the second stop lever 29. The first cylinder 22 is mounted on the mounting plate 24, and its piston rod is hinged to the end of the first stop lever 26. The front ends of the first stop lever 26 and the second stop lever 29 are connected to the vertical stop lever 31, and the roller 30 is disposed at the bottom of the vertical stop lever 31.

[0035] The X-direction position of the first stop lever 26 and the second stop lever 29 can be adjusted by the second cylinder 23, so that the vertical stop lever 31 and the roller 30 are positioned between the second and third steel drums at the rear of the conveyor belt. The first cylinder 22 can control the front ends of the first stop lever 26 and the second stop lever 29 to open to the sides of the conveyor belt or to retract towards the center. When retracted, the roller 30 can block the third steel drum from continuing to move forward. When opened, the third steel drum is allowed to pass and continue to move forward.

[0036] The first single-positioning blocking cylinder 8 and the second single-positioning blocking cylinder 9 are fixed below the conveyor belt. Their telescopic rods can extend upwards through the gap between the conveyor rollers 11. After extending, they can block the steel drum on the conveyor belt from being conveyed forward. After retracting, the blocked steel drum can continue to be conveyed forward. The first single-positioning blocking cylinder 8 is installed near the end of the conveyor belt to block the first steel drum located at the end of the conveyor belt. The distance between the first single-positioning blocking cylinder 8 and the second single-positioning blocking cylinder 9 is greater than the diameter of the steel drum. The second single-positioning blocking cylinder 9 is used to block the second steel drum located at the rear of the conveyor belt.

[0037] The working process of this utility model is as follows:

[0038] 1. Conveyor belt 1 starts to operate, and steel drums are fed from the front end of the conveyor belt. When the first steel drum advances to the distance measuring instrument 5, the conveyor belt 1 stops rotating. The distance measuring instrument 5 detects the diameter of the steel drum and provides feedback. After receiving the feedback, each set of flexible track changing components 4 operates simultaneously to adjust the spacing of the steel wire ropes 6 on both sides to adapt to the measured diameter of the steel drum. Then the conveyor belt 1 continues to rotate, and the steel drum moves forward along the conveying center of the conveyor belt under the action of the steel wire ropes 6.

[0039] 2. The mounting plate 24 is adjusted to a suitable position by the second cylinder 23. The first cylinder 22 controls the opening of the first stop lever 26 and the second stop lever 29, while the second single-position blocking cylinder 9 remains retracted and the first single-position blocking cylinder 8 extends. When the first steel drum is conveyed to the end of the conveyor belt, the first single-position blocking cylinder 8 prevents it from entering the elevator 7. Then, the second single-position blocking cylinder 9 extends to prevent the second steel drum from continuing to be conveyed forward. Next, the first cylinder 22 controls the first stop lever 26 and the second stop lever 29 to retract, preventing the third steel drum and subsequent steel drums from continuing to be conveyed forward.

[0040] 3. Once the steel drum is in position, the elevator 7 receives a signal, and the first single-positioning blocking cylinder 8 retracts, allowing the first steel drum to advance into the elevator, where it is then transferred. Then, the first single-positioning blocking cylinder 8 extends, and the second single-positioning blocking cylinder 9 retracts, causing the second steel drum to advance and be blocked by the first single-positioning blocking cylinder 8. Simultaneously, the first stop lever 26 and the second stop lever 29 open, allowing the third steel drum to pass before retracting to continue blocking subsequent steel drums. The second single-positioning blocking cylinder 9 extends again after the second steel drum passes, blocking the third steel drum. This cycle repeats, with each steel drum transferred by the elevator advancing one position on the conveyor belt until all steel drums have been transferred.

[0041] The above is a further detailed description of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
