Description

Technical Field

[0001] This utility model relates to the field of stacker cranes, and more specifically, to a synchronous belt tensioning mechanism for a light-load stacker crane. Background Technology

[0002] Stacker cranes have significant engineering value in intelligent logistics handling systems and warehousing systems. They are mainly used to receive palletized or binned materials at the warehouse end and deliver materials to the warehouse location. To solve the problem of swaying or loosening of the synchronous belt during operation due to the excessive height of the stacker crane, which may lead to interference with the columns or other moving mechanisms, a synchronous belt tensioning mechanism needs to be installed. This mechanism uses a smooth wheel to press the smooth side of the synchronous belt, thereby adjusting the tension of the synchronous belt during operation and achieving stable operation of the loading platform.

[0003] First, tensioning blocks are placed at the connection points of the synchronous belt, and the tension of the synchronous belt is judged on-site to tighten or loosen it. Second, the vertical position of the upper and lower synchronous belt pulleys is manually adjusted according to the tension of the synchronous belt to achieve tension. Third, a geared or smooth wheel is installed in the middle of the column, with two tensioning methods (compression or tension), and the position of the wheel is manually adjusted to achieve tension.

[0004] Currently, the tightness of the timing belt needs to be judged by visual inspection or manual contact. It also requires manually loosening the tension bolts, tightening them, and then tightening the bolt assembly. The process is cumbersome and wastes a lot of manpower. There is no standard for judging the appropriate tightness.

[0005] Therefore, we have made improvements to this by proposing a synchronous belt tensioning mechanism for light-load stacker cranes. Utility Model Content

[0006] The purpose of this utility model is to address the problems raised in the existing background technology.

[0007] To achieve the above-mentioned objectives, this invention provides a synchronous belt tensioning mechanism for light-load stacker cranes to improve the aforementioned problems.

[0008] The application is as follows:

[0018] As a preferred technical solution of this application, the execution component further includes two polyurethane wheels respectively mounted on two pressure roller supports for adjusting the tension of the timing belt of the light-load stacker.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1, please refer to Figures 1-4 A timing belt tensioning mechanism for a light-duty stacker crane includes a mounting plate 1 installed on a loading platform and raised synchronously therewith. A drive assembly 2 is installed at the bottom of the mounting plate 1, a timing assembly 3 is provided at the top of the mounting plate 1, and an execution assembly 4 that works in conjunction with the timing assembly 3 is provided on the side of the top of the mounting plate 1 away from the timing assembly 3.

[0033] The synchronization component 3 includes a slider 34 disposed on the top of the mounting plate 1. The bottom of the slider 34 is slidably connected to the top of the mounting plate 1. A positioning guide roller 35 is disposed between the slider 34 and the mounting plate 1. By setting the slider 34, when the slider 34 is driven by the gear 32 and the crank connecting rod 31, it can drive the actuator 4 to move, thereby playing the role of adjusting tension.

[0034] A rack 33 is fixedly installed in the middle of the front side of the top of the slider 34. The teeth of the rack 33 face the rear side of the top of the slider 34. By setting the rack 33 and the gear 32, the gear 32 can drive the slider 34 to move left and right.

[0035] The synchronization component 3 also includes a gear 32 disposed on the slider 34. The gear 32 works in conjunction with the rack 33. The gear 32 is connected to the rack 33 so that when the crank connecting rod 31 performs crank-slider motion, it can drive the slider 34 to move left and right, thereby enabling the actuator 4 to achieve the function of adjusting tension.

[0036] The gear 32 is connected to a crank connecting rod 31 via a bearing in the middle, and one end of the crank connecting rod 31 is connected to the top of the mounting plate 1 via a shaft.

[0037] The drive assembly 2 includes a servo motor 21 that is fixedly installed on the bottom of the mounting plate 1 near the loading platform.

[0038] The drive assembly 2 also includes a right-angle planetary reducer 23 located at the bottom of the mounting plate 1 and connected to the long shaft end of the crank connecting rod 31. By setting the right-angle planetary reducer 23, the speed of the servo motor 21 can be reduced, avoiding the problem that the synchronization assembly 3 is difficult to adjust due to excessive speed.

[0039] The drive assembly 2 also includes a coupling 22, which is placed between the servo motor 21 and the right-angle planetary reducer 23, and is fixedly connected to the rotating shafts of the servo motor 21 and the right-angle planetary reducer 23 respectively. By setting the coupling 22, it can connect the rotating shafts of the servo motor 21 and the right-angle planetary reducer 23, so that the servo motor 21 can drive the right-angle planetary reducer 23 to rotate.

[0040] Example 4 further optimizes the timing belt tensioning mechanism for the light-load stacker provided in the above embodiments, such as... Figure 1 and Figure 4 As shown, the execution component 4 includes two pressure roller brackets 42 disposed on the slider 34, and the pressure roller brackets 42 can move horizontally synchronously with the slider 34.

[0041] The execution component 4 also includes two polyurethane wheels 41 respectively mounted on two pressure roller supports 42 for adjusting the tension of the synchronous belt of the light-load stacker. The surface of the polyurethane wheel 41 is equipped with a flexible pressure sensor. The flexible pressure sensor is a known technology. Therefore, how it detects pressure and how it feeds back to the external control system connected to the servo motor 21 controller is not described in detail.

[0042] The usage process of the timing belt tensioning mechanism for the light-load stacker provided by this utility model is as follows:

[0043] When the flexible pressure sensor on the polyurethane wheel 41 detects the tension of the synchronous belt at the moment of operation, the servo motor 21 controls the coupling 22 and the right-angle planetary reducer 23 to rotate the crank connecting rod 31. When the crank connecting rod 31 rotates, it can drive the gear 32, rack 33 and slider 34 to move horizontally. The polyurethane wheel 41 and the pressure wheel bracket 42 move horizontally with the slider 34. When the polyurethane wheel 41 moves towards the synchronous belt, it presses the synchronous belt; conversely, it loosens the synchronous belt, thus adjusting the tension of the synchronous belt.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
