[0002] With the continuous improvement of industrial production automation, material handling equipment is playing an increasingly important role in various production scenarios.

[0003] Traditional hoisting equipment often uses fixed lifting beams or simple moving mechanisms, which often makes it difficult to accurately position and stably support heavy objects during hoisting. This is especially true when hoisting objects with irregular shapes or unstable centers of gravity, which can easily lead to safety hazards such as displacement, shaking, or even slippage.

[0004] In addition, existing lifting devices usually lack effective lateral positioning functions, making it difficult to flexibly adjust according to the size and shape of the object being lifted, resulting in complex operation, low efficiency, and high dependence on the experience of the operators.

[0015] The electric cross-shaped lifting beam provided in this embodiment of the utility model, compared with the prior art:

[0016] 1. This utility model features an innovatively designed electric cross-shaped lifting beam. The four sets of vertical beams form a cross-shaped structure, which not only improves overall stability and load-bearing capacity but also provides balanced support in different directions, ensuring the load remains balanced during lifting and reducing safety hazards caused by load shifting.

Detailed Implementation

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8 This utility model embodiment provides an electric cross lifting beam, including a lifting ring column 1, which can be connected to lifting equipment. Four sets of crossbeams 2 are installed on the outer side of the lifting ring column 1. The four sets of crossbeams 2 form a cross shape, which improves the overall stability and load-bearing capacity, and also provides balanced support in different directions, ensuring that the heavy object remains balanced during the lifting process and reducing safety hazards caused by load offset.

[0031] Each crossbeam 2 is slidably equipped with a lifting ring mechanism, which includes a slider 3 that slides on the outside of the crossbeam 2. The lower end of the slider 3 is fixedly connected to a vertical beam 4, and the lower end of the vertical beam 4 is rotatably equipped with a connecting sleeve 5. The connecting sleeve 5 is used to connect with the object to be lifted to realize the lifting operation.

[0032] Furthermore, a lead screw 22 is rotatably mounted on the lower side of the crossbeam 2. The lead screw 22 is driven to rotate by a motor and forms a threaded connection with the slider 3. By controlling the operation of the motor, the lead screw 22 is driven to rotate in both directions, thereby driving the slider 3 to move along the length of the crossbeam 2, which in turn drives the vertical beam 4 and the connecting sleeve 5 to move, realizing flexible adjustment of the lifting point position to adapt to the lifting needs of objects of different sizes or shapes.

[0033] To improve the stability and guiding performance of the slider 3 when sliding on the crossbeam 2, a groove 31 is provided inside the slider 3, and sliding strips 21 that cooperate with the groove 31 are provided on both sides of the crossbeam 2. The two are slidably connected to ensure that the slider 3 runs smoothly and reliably.

[0034] To enhance the controllability and positioning stability of the connecting sleeve 5 during rotation, this invention also includes a vertical beam 4 extending through the pivot of the connecting sleeve 5 and fixedly connected to the ratchet 6. A pawl 7, engaging with the ratchet 6, is rotatably mounted on the lower part of the vertical beam 4 and connected to a fixed seat on the vertical beam 4 via a spring 8, ensuring that the pawl 7 always tends to return to its original position towards the ratchet 6.

[0035] An auxiliary positioning mechanism is installed on one side of the lifting ring mechanism to further enhance the stability of the object during hoisting. Specifically, the auxiliary positioning mechanism includes cylinders 9 installed on both sides of the vertical beam 4. The piston ends of the two sets of cylinders 9 are respectively connected to two sets of mounting plates 91. Positioning plates 94 are slidably installed in the grooves opened in the two sets of mounting plates 91. Positioning heads 95 are installed on the lower side of the positioning plates 94. The two sets of positioning plates 94 are connected by an arc-shaped connecting plate to enhance the coordination and adaptability of the overall structure.

[0036] When the hoisting operation begins, the cylinder 9 drives the mounting plate 91 to move downward, causing the positioning head 95 to approach the side wall of the object being hoisted; at the same time, the positioning plate 94 slides inside the mounting plate 91, so that the positioning head 95 can fit the surface of objects of different shapes and sizes, thereby effectively preventing shaking or displacement during the hoisting process.

[0037] In one of the two mounting plates 91, a limiting rod 92 is fixedly installed inside the mounting plate 91, and a set of corresponding positioning plates 94 forms a sliding fit with the limiting rod 92, which plays a guiding and limiting role; a second lead screw 93 is rotatably installed inside the other mounting plate 91. The second lead screw 93 is driven to rotate by a motor and is threadedly connected to another set of positioning plates 94, thereby realizing the automatic adjustment function of the positioning head 95 on this side, improving the convenience of operation and the degree of automation.

[0038] Furthermore, a mounting hole 11 is provided at the lower part of the lifting ring column 1. A hollow rod 12 is inserted into the mounting hole 11 and fixed with bolts for easy disassembly and replacement. A positioning rod 13 is slidably arranged inside the hollow rod 12. A spring 14 connects the positioning rod 13 to the inner wall of the mounting hole 11, allowing the positioning rod 13 to extend and retract within a certain range. When the object being lifted is high or large, the positioning rod 13 can be compressed and retracted into the hollow rod 12; when lifting smaller objects, the positioning rod 13 extends under the action of the spring 14 and contacts the top of the object, achieving an auxiliary positioning function.

[0039] If the positioning rod 13 is inconvenient to use when encountering objects of special size or shape, the entire hollow rod 12 can be removed from the mounting hole 11 without affecting the overall flexibility of the device.

[0040] In summary, the working principle of the electric cross-beam of this utility model embodiment is as follows: the lifting ring column 1 is connected to the lifting equipment, the motor drives the lead screw 22 to rotate, which drives the slider 3 to move along the cross beam 2, adjusting the position of the vertical beam 4 and the connecting sleeve 5. The connecting sleeve 5 achieves self-locking through the ratchet 6 and pawl 7 structure to prevent accidental rotation. The cylinder 9 drives the mounting plate 91 to descend, so that the positioning head 95 is close to the side wall of the object being lifted. The positioning plate 94 slides in the mounting plate 91 to ensure that the positioning head 95 is in contact with the surface of the object. The positioning rod 13 in the hollow rod 12 extends under the action of the spring 14 and contacts the top of the object to further enhance the positioning effect.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
