Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulk material storage equipment for warehouses, specifically to a walking drive device for a traveling scraper and material handling equipment. Background Technology
[0002] Currently, in room-type warehousing, the material feeding scheme is mostly top-feed, with material piles spaced along the length of the warehouse. Due to the angle of accumulation, the material piles are often conical, resulting in low warehouse volume utilization. Therefore, a traveling scraper-type material handling device is needed to level the material. During scraping and handling, the material will press against the equipment, requiring its drive mechanism to force movement to ensure it can be pushed. This device uses two single-sided drive mechanisms, and the structure of these two drive mechanisms and how to ensure they travel the same distance to prevent tilting are crucial considerations. Therefore, a drive mechanism for the traveling scraper-type material handling equipment needs to be designed that can force movement while also detecting and automatically adjusting the positions of the two single-sided drive mechanisms to prevent tilting. Utility Model Content

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0016] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0017] Reference Figures 1 to 7The illustrated driving device for a traveling scraper and material handling equipment includes a traveling track assembly 1, a traveling end beam assembly 2, a mounting base 3, a power assembly 4, a traveling drive sprocket assembly 5, a drive sprocket encoder assembly 6, and a driven sprocket encoder assembly 7. The traveling track assembly 1 is arranged along the length of the warehouse. The mounting base 3 is fixedly mounted on the traveling end beam box. The power assembly 4 is fixed on the mounting base 3. The traveling drive sprocket assembly 5 is connected to the low-speed shaft end coupling 5a of the power assembly 4 via a pin 5b. The traveling track assembly 1 includes a toothed track 1a. The traveling drive sprocket assembly 5 is provided with a drive sprocket 5c that meshes with the toothed track 1a. The power assembly 4 drives the traveling drive sprocket assembly 5 to work, enabling the traveling drive sprocket 5c to travel on the traveling track assembly 1. Furthermore, the driving sprocket 5c has strong power when meshing with the toothed track 1a, enabling the equipment to move under forced engagement. The driving sprocket encoder assembly 6 is fixed to the mounting base 3, and during movement, it records the number of rotations of the driving sprocket 5c. The driven sprocket encoder assembly 7 is fixed to the mounting base 3, and during movement, it records the number of rotations of the driven sprocket 7a. The driven sprocket 7a meshes with the toothed track 1a, and the rotation count provides feedback on the operating position of the device. Each traveling scraper and material handling equipment has two driving devices, and the recorded rotation counts are transmitted to the controller via the driven sprocket encoder assembly 7 in each device. The controller analyzes and determines whether the traveling device is skewed. If the rotation counts are the same, the program determines that the traveling device is not skewed; otherwise, if the counts are different, it indicates skewness.
[0018] When a misalignment occurs, the two drive units start asynchronously. The drive unit that travels a shorter distance (i.e., rotates fewer times) can accelerate to catch up with the other encoder's rotation count, thus correcting the misalignment. Upon subsequent movement, the trolley can then move in a straight line.
[0019] The driven sprocket encoder assembly 7 is fixed on the mounting base 3. The driven sprocket encoder assembly 7 records the actual distance the device moves relative to the toothed track 1a, serving as a means of mutual calibration with the driving sprocket encoder assembly 6. Although the driving sprocket encoder assembly 6 can record the number of rotations of the driving sprocket 5c, there may be instances of travel malfunctions. By recording the travel distance using the driven sprocket encoder assembly 7 and comparing it with the travel distance of the power assembly 4 recorded by the driving sprocket encoder assembly 6, it is possible to determine whether a malfunction has occurred during the travel process.
[0020] One drive unit is installed at each end of the overhead crane. At least two drive units are needed to move the overhead crane-type scraper and material handling equipment on the crossbeams of the warehouse.
[0021] The traveling end beam assembly 2 has multiple driven wheels, and the traveling track assembly 1 also includes a steel rail 1b, on which the multiple driven wheels roll and move. The movement of the traveling end beam assembly 2 on the traveling track assembly 1 is achieved through the driven wheels and the steel rail 1b.
[0022] The active sprocket encoder assembly 6 includes gear 6a, encoder bracket 6b, encoder bearing housing 6c, and active sprocket encoder 6d. The active sprocket encoder 6d is coaxially connected to gear 6a and is used to detect the number of rotations of gear 6a. The traveling active sprocket assembly 5 includes gear 5e, which meshes with gear 6a. Through the meshing transmission between these two components, the number of rotations of the active sprocket 5c is transmitted to the active sprocket encoder 6d, which then transmits the detected data to the controller for further data processing.
[0023] The power assembly 4 includes a motor 4a, a brake 4b, a brake wheel 4c, and a reducer 4d. The motor 4a drives the reducer 4d to rotate via the brake wheel 4c. The brake 4b is used to quickly stop the motor 4a and maintain it at a stop. When movement is required, both the motor 4a and the brake 4b are energized simultaneously. When the machine is stopped, the brake 4b locks the brake wheel 4c, preventing it from rotating.
[0024] The driving sprocket assembly 5 also includes a driving sprocket bearing housing 5d and a driving sprocket 5c. One end of the driving sprocket 5c is provided with a shaft, which is inserted into the driving sprocket bearing housing 5d and can rotate. The other end of the driving sprocket 5c is provided with a flange, and a pin 5b is fixedly connected to the flange. A coupling 5a is provided with a sliding hole for the pin 5b to pass through. Gear 5e is fixedly connected to the coupling 5a, and the coupling 5a is fixedly connected to the output shaft of the reducer 4d. When the reducer 4d operates, it can drive gear 5e and driving sprocket 5c to move simultaneously. If the pin 5b breaks, 5a will not be able to drive the sprocket to rotate.
[0025] The driven sprocket encoder assembly 7 includes a driven sprocket 7a, an encoder bracket 7b, an encoder bearing housing 7c, and a driven sprocket encoder 7d. The driven sprocket 7a meshes with the toothed track 1a and is rotatably mounted on the encoder bearing housing 7c. The encoder bearing housing 7c is fixedly mounted on the encoder bracket 7b. The driven sprocket encoder 7d is coaxially connected to the driven sprocket 7a and monitors the number of rotations of the driven sprocket 7a. During the movement of the traveling scraper-type material handling equipment, the toothed track 1a meshes and drives the driven sprocket 7a to rotate. The driven sprocket encoder 7d records the number of rotations of the driven sprocket 7a, and the controller identifies the actual distance traveled by the driving device. The main function of the driven sprocket encoder 7d is to prevent a deviation in the values of the driving encoder and the driven encoder when the pin 5b breaks, the drive sprocket 5c breaks a tooth, or the toothed track 1a breaks a tooth. This causes an alarm and shutdown of the system, allowing the user to replace the parts in time and protect the equipment.
[0026] This traveling scraper and material handling drive unit uses two driven sprocket encoders to record the number of sprocket rotations in real time to determine the running position at both ends of the equipment. The program determines whether the traveling trolley is skewed, and if skewed, the two single-sided travel drive units are activated asynchronously to correct the deviation. Furthermore, the driving sprocket has strong power to mesh with the toothed track, enabling the equipment to move under forced engagement.
[0027] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
