[0002] Stacker cranes are core automated material handling equipment in logistics warehousing and industrial production. They mainly consist of adjustable clamping devices, lifting mechanisms, traveling mechanisms, and control systems. The clamping devices stably hold various types of goods, such as boxes, bags, and drums. Combined with the lifting mechanism, they enable the stacking and retrieval of goods on shelves of different heights. At the same time, the traveling mechanism completes horizontal transfer within the warehouse. They are widely used in e-commerce warehousing, manufacturing workshops, cold chain logistics, chemical storage areas, and other scenarios.

[0003] In existing technologies, the anti-fall devices used in clamping stacker cranes have a large number of parts and require a large number of parts to be assembled. The installation process of the safety clamp is relatively complicated. It not only requires professional personnel to accurately align the relative positions of the transmission mechanism and the clamping lifting track, but also requires repeated adjustments to the fit clearance between various parts. It often requires the use of special calibration instruments to complete the installation, which greatly increases the difficulty and time cost of installation. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and anti-fall device for stacker crane columns in order to solve the above problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0033] To make the objectives, technical solutions, and advantages of the embodiments 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.

[0034] like Figures 1-6As shown, in one embodiment, a stacker crane column anti-fall catcher includes: a loading platform 2 installed on a rectangular tube column 1, the loading platform 2 being used to carry goods to be stacked, ensuring that the loading platform 2 can be smoothly raised and lowered along the vertical direction of the rectangular tube column 1, avoiding lateral deviation.

[0035] The rectangular tube column 1 is equipped with a safety clamp 3 on its side, and a linkage mechanism 4 is provided on the outside of the safety clamp 3. The linkage mechanism 4 is used to drive the safety clamp 3 to clamp the rectangular tube column 1. In the event of an abnormal fall of the loading platform 2, the safety clamp 3 can be tightened through mechanical linkage, so that the safety clamp 3 clamps the outer wall of the rectangular tube column 1. The static friction force generated by the clamping surface is used to counteract the gravity of the loading platform 2, thereby preventing the loading platform 2 from falling and ensuring the safety of goods and equipment.

[0036] Please continue reading. Figures 1-6 In this embodiment, the safety clamp 3 includes a base 31 with symmetrical threaded holes on the side of the base 31, and a high-strength screw 32 is fitted into the threaded holes; correspondingly, a wedge block 33 is inserted into the screw 32 along the axial direction. The wedge block 33 has a trapezoidal structure, and the side near the rectangular tube column 1 is a plane that fits the outer wall of the column; and a guide plate 34 is engaged on the outside of the wedge block 33 to prevent the wedge block 33 from shifting during operation.

[0037] Specifically, a magnet 35 is installed on the inner wall of the wedge block 33, and the magnet 35 is attracted and attached to the base 31.

[0038] Understandably, the magnet 35 can use its strong attraction force to firmly fix the wedge block 33 to the base 31, effectively offsetting the impact force on the wedge block 33 during equipment operation (such as lifting of the loading platform 2 and machine vibration), preventing the wedge block 33 from moving back and forth, thereby ensuring the clamping accuracy of the safety clamp 3 and preventing the anti-fall function from failing due to the displacement of the wedge block 33.

[0039] Please continue reading. Figures 1-6 In this embodiment, the linkage mechanism 4 includes a linear guide rail 41, which is fixed parallel to the side frame of the loading platform 2 by bolts; correspondingly, a guide rail connector 42 is installed on the side of the linear guide rail 41. The guide rail connector 42 is a T-shaped metal bracket that can slide smoothly along the track of the linear guide rail 41 without jamming; and a movable connecting rod 43 and a wedge joint 44 are respectively installed at the end of the guide rail connector 42.

[0040] Specifically, the linear guide rail 41 is slidably connected to the guide rail connector 42 via a slide table. The linear guide rail 41 is installed on the loading platform 2 to ensure that the guide rail connector 42 can move smoothly along the track direction (i.e., the vertical direction) of the linear guide rail 41, so as to avoid jamming or deviation when the linkage mechanism 4 is in motion, to ensure the transmission accuracy of the linkage mechanism 4, and to ensure that the safety clamp 3 can respond to the trigger signal in a timely manner.

[0041] Furthermore, the movable linkage 43 is located at one end of the guide rail connector 42. The movable linkage 43 is detachably connected to the screw 32, which facilitates quick disassembly and separation during equipment maintenance without disassembling the entire safety clamp 3 or linkage mechanism 4, thus reducing maintenance difficulty and time costs.

[0042] Correspondingly, a wedge-shaped joint 44 is provided at the other end of the guide rail connector 42. A steel wire pull rope is connected to the end of the wedge-shaped joint 44, which can stably transmit the tension of the pull rope to the guide rail connector 42 and withstand the instantaneous impact force when the loading platform 2 falls, thus avoiding the failure of the transmission due to joint breakage.

[0043] It should be noted that a tension spring 45 is provided on one side of the wedge joint 44. One end of the tension spring 45 is connected to the middle of the guide rail connector 42, and the other end of the tension spring 45 is connected to the tension connector 7. The tension connector 7 is installed on the loading platform 2.

[0044] Understandably, the tension spring 45 can limit the guide rail connector 42 to the bottom of the linear guide rail 41, preventing the linkage mechanism 4 from moving up and down along the linear guide rail 41 when the machine vibrates. This effectively solves the problem of the loading platform 2 locking due to accidental triggering of the safety clamp 3. This design achieves the initial position locking of the linkage mechanism 4 through mechanical elasticity, without the need for additional electric or hydraulic locking components, simplifying the structure and improving the stability of equipment operation, reducing the probability of the loading platform 2 locking and stopping due to accidental triggering of the safety clamp.

[0045] Please continue reading. Figures 1-6 In this embodiment, an adjustment pad 5 is provided on the side of the loading platform 2. It can be made of wear-resistant and rigid materials (such as epoxy resin board) to precisely adjust the gap between the wedge block 33 and the rectangular tube column 1.

[0046] Specifically, the distance between the wedge block 33 and the rectangular tube column 1 is 3-4 mm.

[0047] It should be noted that an adjusting bolt 6 is installed on the outside of the base 31. By rotating the adjusting bolt 6 clockwise or counterclockwise, the base 31 can be moved horizontally (towards or away from the rectangular tube column 1), thereby adjusting the position of the wedge block 33 driven by the base 31, and realizing the fine adjustment of the distance between the wedge block 33 and the column.

[0048] It is understandable that the loading platform 2 is equipped with an adjustment pad 5 on the side and an adjustment bolt 6 is installed on the outside of the base 31. Before operation and debugging, the adjustment bolt 6 can be loosened and the distance between the wedge block 33 and the rectangular tube column 1 can be adjusted by adjusting the adjustment pad 5. The spacing can be adjusted by simply selecting the thickness of the adjustment pad 5 and rotating the adjustment bolt 6. The operation is simple and the adjustment accuracy is high, which can meet the spacing requirements of rectangular tube columns 1 of different specifications or different usage scenarios.

[0049] For example, before operation and commissioning, it is necessary to adjust the distance between the wedge block 33 on the safety clamp 3 and the rectangular tube column 1 (e.g., 3.5mm). Therefore, the provided adjustment pad 5 of corresponding thickness can be inserted from the bottom of the safety clamp 3 between the wedge block 33 and the rectangular tube column 1. Then, rotate the adjustment bolt 6 on the outside of the base 31 clockwise until the end of the bolt is in contact with the side of the loading platform 2, ensuring that the base 31, the adjustment pad 5 and the rectangular tube column 1 are in close contact. Then, slowly pull the adjustment pad 5 out of the gap. During the pulling process, a uniform speed should be maintained to avoid the wedge block 33 from shifting due to excessive force. Finally, put the adjustment pad 5 back in its original position.

[0050] Working principle: When the loading platform 2 falls rapidly, the wedge joint 44 on the linkage mechanism 4, which is connected to the wire rope, will be subjected to a vertical upward pulling force. This force will drive the linear guide rail 41 to move upward through the guide rail connector 42, thereby driving the moving linkage 43 to move synchronously. The wedge block 33 will then move upward through the screw 32, thereby clamping the rectangular tube column 1 and stopping the loading platform 2 from falling.

[0051] Through the above technical solution, the entire fall arrestor of this application has a simple structure and is easy to install, which can effectively reduce manufacturing costs and improve installation efficiency.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
