Description

Technical Field

[0001] This utility model belongs to the field of cargo platform guide wheel technology, specifically relating to an adaptive guide wheel adjustment device for a stacker crane cargo platform. Background Technology

[0002] Stacker cranes are the core logistics handling equipment in modern intelligent warehousing, mainly performing functions such as outbound, inbound, and turnover. The high efficiency and wide range of applications of stacker cranes are the future trend of continuous development. In the process of using stacker cranes, most stacker cranes adopt double columns, that is, the loading platform is installed between two columns. The lifting mechanism of the loading platform drives the loading platform to move in a straight line along the columns to lift or lower.

[0003] However, as the guide wheels on the loading platform wear out over time, they can easily become misaligned. This can lead to uneven force distribution or mechanical structural problems causing the loading platform of the stacker crane to shift position during operation. Such misalignment can seriously affect the operating accuracy and stability of the stacker crane, and may even lead to equipment failure or safety accidents. The guide wheels are also unable to adaptively adjust the gap between themselves and the stacker crane columns according to their wear condition.

[0004] Therefore, an adaptive guide wheel adjustment device for the stacker crane loading platform is proposed. Summary of the Invention

[0005] This invention provides an adaptive guide wheel adjustment device for a stacker crane loading platform, the purpose of which is to solve the problems mentioned above.

The self-locking assembly includes: grooves respectively formed on the outer wall of the two support arms facing each other; a moving block embedded in the groove; a guide post disposed at the center of the outer wall of the moving block; and an auxiliary spring disposed between the outer wall of the moving block and the inner wall of the groove; and wedges equally spaced on the outer wall of the two moving blocks facing each other.

[0007] Furthermore, mounting holes are provided at equal intervals on one side outer wall of the support arm, and the support arm and the guide wheel platform are fixed together by bolts, the bolts passing through the mounting holes, and ear plates are provided on the top and bottom side walls of the support platform.

[0008] Furthermore, both the outer sidewalls and bottom of the sliding table one and the sliding table two are provided with sliders, and the inner sidewall of the bearing platform is provided with a groove that matches the slider.

[0009] Furthermore, the guide post passes through one side wall of the movable block and also passes through the auxiliary spring.

[0010] Furthermore, the wedge has a right-angled triangular cross-section, and the wedges on the two moving blocks are in an interlocking state with the contact surface being an inclined plane.

[0011] Furthermore, the guide wheel protrudes from one side wall of the support platform, and the axes of the two guide wheels are on the same horizontal plane.

[0012] Furthermore, the top of the support platform is provided with a cavity for mounting the main spring and for the sliding platform one and sliding platform two to move.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] Reference Figure 1 , Figure 3 and Figure 4 This utility model embodiment proposes an adaptive guide wheel adjustment device for a stacker crane loading platform, including a support platform 1. A cavity is formed at the top of the support platform 1. Two main springs 2 are symmetrically arranged on the inner wall of the cavity. A sliding platform 3 and a sliding platform 4 are respectively provided at one end of each main spring 2. The sliding platforms 3 and 4 are mirror images of each other. Slider blocks 10 are provided on the outer walls and bottom of the sliding platforms 3 and 4. A groove 11 adapted to the slider 10 is formed on the inner wall of the support platform 1. Support arms 5 are provided on the outer walls of the opposite sides of sliding platform 3 and sliding platform 4. The two support arms 5 are staggered, and guide wheel platforms 6 are provided on the outer walls of the two support arms 5. Guide wheels 7 are rotatably connected to the center of the outer wall of the guide wheel platform 6 away from the support arm 5. The guide wheels 7 protrude from the side wall of the bearing platform 1, and the axes of the two guide wheels 7 are on the same horizontal plane. The outer walls of the two guide wheels 7 are attached to the column of the stacker crane to play a guiding role and ensure the stability of the stacker crane loading platform lifting.

[0027] On the outer wall of each of the two opposing support arms 5, a groove 81 for the self-locking assembly 8 is provided. A movable block 82 is embedded and fitted inside the groove 81. A guide post 83 is provided at the center of one outer wall of the movable block 82, and an auxiliary spring 84 is provided between one outer wall of the movable block 82 and one inner wall of the groove 81. The guide post 83 passes through one side wall of the movable block 82 and through the auxiliary spring 84. The guide post 83 provides a guiding function, allowing the movable block 82 to move linearly within the groove 81, thereby controlling the movable block 82. The wedges 85 on the 2nd and the deformation and reset capability of the auxiliary spring 84 can make the two moving blocks 82 tightly connected. Several wedges 85 are evenly spaced on the outer wall of the moving block 82 away from the support arm 5. The cross-section of the wedges 85 is a right-angled triangular structure. The wedges 85 on the two moving blocks 82 are in an interlocking state and the contact surface is an inclined surface. The interlocking of the wedges 85 on the two moving blocks 82 forms a one-way limiting structure, which makes the two support arms 5 only move towards each other, thereby achieving a self-locking effect and preventing the two support arms 5 from moving in opposite directions.

[0028] In order to ensure that the guide wheel 7 adaptively fits against the outside of the stacker crane column, in this embodiment, the support platform 1 is installed on the loading platform, and the two guide wheels 7 are fitted against the outer wall of the stacker crane column. When the guide wheel 7 wears out after long-term use, a gap is generated between the guide wheel 7 and the column. Under the push of the main spring 2, the sliding platform 1 3 and the sliding platform 2 4 move towards each other and slide inside the support platform 1. The support arm 5 on the sliding platform 1 3 and the sliding platform 2 4 and the guide wheel 7 move synchronously, and the guide wheel 7 can continue to fit tightly against the outer wall of the column.

[0029] As the support arm 5 moves, the self-locking assembly 8 between the two support arms 5 achieves one-way locking. Specifically, the two moving blocks 82 move towards each other, and the wedges 85 on the two moving blocks 82 contact each other. Under the guidance of the inclined surface on the wedges 85 and the guide post 83, the horizontal lateral thrust on the wedges 85 is converted into a horizontal longitudinal thrust. At this time, the moving blocks 82 move towards the inside of the groove 81, and the wedges 85 on the two moving blocks 82 interlock. The positions of the two support arms 5 are locked, thereby achieving the locking of the positions of the two guide wheels 7, ensuring that the guide wheels 7 are tightly attached to the column, and preventing the center of the guide wheels 7 from shifting.

[0030] Example 2

[0031] Reference Figure 1 , Figure 2 and Figure 5Based on the above embodiments, this utility model embodiment also proposes an adaptive guide wheel adjustment device for a stacker crane loading platform, including two support arms 5, and guide wheel platforms 6 of different thicknesses are respectively installed on one side outer wall of the two support arms 5. A guide wheel 7 is rotatably connected to the center of the side outer wall away from the support arm 5 on the guide wheel platform 6. Mounting holes 9 are equally spaced on one side outer wall of the support arm 5, and the support arm 5 and the guide wheel platform 6 are fixedly connected by bolts, with the bolts passing through the mounting holes 9. Ear plates 12 are provided on the top and bottom side walls of the loading platform 1.

[0032] In order to adjust the spacing between the two guide wheels 7 according to the needs of columns of different widths, in this embodiment, the guide wheel platform 6 is installed and fixed at different positions of the support arm 5 according to the distribution of the mounting holes 9 on the support arm 5, thereby adjusting the initial spacing value of the two guide wheels 7. The two locked support arms 5 can be unlocked by the outwardly extending guide post 83. Specifically, by pulling the guide post 83 outward, the moving block 82 at one end of the guide post 83 moves into the groove 81. At this time, a gap is generated between the two moving blocks 82, and the wedge block 85 separates. This allows the sliding table 1 3 and sliding table 2 4 to move in opposite directions, which facilitates the reset of the support arm 5 position.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
