Description

Technical Field

[0001] This invention relates to the field of crane lifting equipment technology, specifically a multi-functional electric tilting lifting equipment. Background Technology

[0002] In modern industrial production, logistics and heavy equipment manufacturing, hoisting operations are an indispensable key link. Traditional lifting tools mostly use fixed hooks, wire ropes or rigid clamps, which are suitable for lifting objects of specific shapes or sizes. However, when faced with workpieces of different specifications, especially those that need to be flipped, positioned or stably clamped (such as large plates, steel structure components, precast concrete parts, etc.), they often have problems such as poor adaptability, cumbersome operation and insufficient safety. To improve lifting efficiency and operational flexibility, various electric lifting devices with adjustable spans or tilting functions have emerged in recent years. For example, some existing technologies use a motor-driven sprocket to drive a chain to achieve workpiece tilting (authorization announcement number CN211971500U), or use a screw mechanism to adjust the distance between the lifting points on both sides to adapt to loads of different widths. However, these devices generally have defects in use: the tilting and clamping functions are independent of each other, and it is impossible to simultaneously achieve stable constraint on the lifted object during the tilting process, which can easily lead to workpiece slippage or swaying, posing safety hazards. In addition, during actual lifting operations, especially when the center of gravity of the lifted object shifts or a large-angle tilting is required, without effective auxiliary stabilization measures, it is very easy to cause swinging, overturning, or even hook detachment accidents. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a multi-functional electric tilting lifting device, which effectively solves the technical problems of traditional lifting devices such as single function, unstable clamping, easy damage to workpieces, and inconvenient adjustment. It has the advantages of reasonable structure, safety and efficiency, and wide applicability, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional electric tilting lifting device, comprising a lifting beam, wherein the lifting beam is provided with two tilting components arranged opposite to each other and a gap adjustment mechanism for driving the two tilting components to move synchronously relative to each other or in opposite directions; the tilting component includes a support base, the support base is provided with a reducer, the output end of the reducer is provided with a sprocket, the sprocket is adapted to a chain, the lower end of the chain is open and connected to a sling, and the sling and the chain are connected to form a loop; The lower part of the lifting beam is also provided with a stabilizing component that acts on the suspended object; the stabilizing component includes a driving device that drives the connecting frame to move up and down. The connecting frame is a rectangular frame structure. Both ends of the sling pass through the internal cavity of the connecting frame and are respectively connected to the two ends of the chain. The driving device drives the connecting frame to move so that the sling wraps around the suspended object.

[0005] Preferably, the stabilizing component further includes two sets of steel wire ropes, which are located on both sides of the drive device. The internal cavity of the connecting frame is slidably fitted with clamps corresponding to the ends of the suspended object. One end of the steel wire rope is connected to the lifting beam, and the other end of the steel wire rope passes around the redirecting wheel on the connecting frame and is connected to the clamps through a spring.

[0006] Preferably, the pitch adjustment mechanism includes a bidirectional lead screw and a motor. The bidirectional lead screw is rotatably installed inside the lifting beam, and the motor is located at the end of the lifting beam and drives the bidirectional lead screw to rotate. Both reverse threaded sections of the bidirectional lead screw are equipped with lead screw nut seats, and the lead screw nut seats are connected to the support seat of the flipping assembly.

[0007] Preferably, the reducers of both of the flipping components drive the corresponding sprockets to rotate synchronously in the same direction.

[0008] Preferably, the clamping plate is provided with a rubber cushioning pad on the side facing the suspended object.

[0009] Preferably, the sling is made of a flexible, wear-resistant material, and its surface is provided with anti-slip texture or covered with a rubber layer.

[0010] Preferably, the upper center of the lifting beam is provided with a lifting lug.

[0011] Preferably, the driving device is one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. By integrating the gap adjustment mechanism, the tilting component and the stabilizing component into one unit, the four functions of hoisting, tilting, clamping and stabilizing are realized in a coordinated manner. It can be applied to objects of different lengths, widths and shapes (such as steel plates, beams and columns, precast components, etc.), which significantly improves the versatility and operational flexibility of the equipment. 2. The two tilting components are driven by a reducer to rotate the sprocket synchronously in the same direction, ensuring that the force is uniform and the movement is coordinated during the tilting process of the lifting belt carrying the suspended object. This effectively avoids workpiece tilting, twisting or slipping due to asynchrony, and improves the safety and accuracy of the tilting operation. 3. The slings, in conjunction with the connecting frame, press down to achieve a wrap-around clamping of the suspended object; at the same time, through the end limiting structure composed of wire rope, reversing wheel, spring and clamping plate, a pre-tightening force is automatically applied during the downward movement of the connecting frame, so that the clamping plate fits the end of the suspended object, which has a dual effect.

[0013] 4. The structure of the motor-driven bidirectional lead screw and lead screw nut seat allows for quick and precise adjustment of the distance between the two tilting components, adapting to objects of different widths. In summary, this invention effectively solves the technical problems of traditional lifting tools, such as limited functionality, unstable clamping, easy damage to workpieces, and inconvenient adjustment. It has the advantages of reasonable structure, safety and efficiency, and wide applicability. Attached Figure Description

Detailed Implementation

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0017] Please see Figure 1-5 The present invention provides the following technical solutions: Example 1: A multi-functional electric tilting lifting device includes a lifting beam 1, which has two opposing tilting components 3 and a gap adjustment mechanism 2 for driving the two tilting components 3 to move synchronously relative to each other or in opposite directions. The tilting component 3 includes a support base, which has a reducer 3.1. The output end of the reducer 3.1 has a sprocket 3.2, which is adapted to a chain 3.3. The lower end of the chain 3.3 is open and connected to a sling 3.4, and the sling 3.4 and the chain 3.3 are connected in a loop. When the object being lifted is lifted, the reducer 3.1 drives the sprocket 3.2 to rotate, the sprocket 3.2 drives the chain 3.3 to move, the chain 3.3 drives the sling 3.4 to move, and the sling 3.4 drives the object being lifted to tilt through static friction, which can achieve tilting at any angle. To ensure the stability of the suspended object during the flipping process, a stabilizing component 4 is also provided at the lower part of the lifting beam 1. The stabilizing component 4 includes a driving device 4.1, which drives the connecting frame 4.2 to move up and down. The connecting frame 4.2 is a rectangular frame structure. Both ends of the sling 3.4 pass through the internal cavity of the connecting frame 4.2 and are respectively connected to the two ends of the chain 3.3. The driving device 4.1 drives the connecting frame 4.2 to move so that the sling 3.4 wraps around the suspended object. That is, the driving device 4.1 drives the connecting frame 4.2 to move down, and the connecting frame 4.2 compresses the sling 3.4, realizing a wrap-around clamping of the suspended object, preventing swaying during transportation, and ensuring safe lifting. The driving device 4.1 is one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. Specifically, the gap adjustment mechanism 2 includes a bidirectional lead screw 2.2 and a motor 2.3. The bidirectional lead screw 2.2 is rotatably installed inside the lifting beam 1, and the motor 2.3 is located at the end of the lifting beam 1 and drives the bidirectional lead screw 2.2 to rotate. Both reverse threaded sections of the bidirectional lead screw 2.2 are fitted with lead screw nut seats 2.1, and the lead screw nut seats 2.1 are connected to the support seat of the tilting assembly 3. By using the structure of the motor 2.3 driving the bidirectional lead screw 2.2 in conjunction with the lead screw nut seats 2.1, the gap between the two tilting assemblies 3 can be quickly and accurately adjusted to accommodate objects of different widths. It should be noted that the reducers 3.1 of the two flipping components 3 drive the corresponding sprockets 3.2 to rotate synchronously and in the same direction, ensuring that the lifting belt 3.4 drives the object being lifted to rotate evenly and with coordinated movements, effectively avoiding workpiece tilting, twisting or slipping due to asynchrony, and improving the safety and accuracy of the flipping operation.

[0018] Example 2: Unlike Example 1, the stabilizing component 4 also includes two sets of wire ropes 4.3, which are located on both sides of the drive device 4.1. The connecting frame 4.2 has slidingly fitted clamping plates 4.6 on both sides of its internal cavity, corresponding to the ends of the suspended object. One end of each wire rope 4.3 is connected to the lifting beam 1, and the other end passes over the redirecting wheel 4.4 on the connecting frame 4.2 and is connected to the clamping plate 4.6 via a spring 4.5. The downward pressure of the connecting frame 4.2 achieves a wraparound gripping effect on the suspended object. During clamping, an end-limiting structure consisting of wire rope 4.3, redirecting wheel 4.4, spring 4.5, and clamping plate 4.6 automatically applies pre-tension to the end of the suspended object. That is, when the connecting frame 4.2 moves downward, the wire rope 4.3 pulls the clamping plate 4.6 to slide within the connecting frame 4.2, converting the downward movement of the connecting frame 4.2 into the translation of the clamping plate 4.6, so that the clamping plate 4.6 fits against the end of the workpiece. This dual stabilizing mechanism further enhances the overall clamping rigidity, achieving two goals at once and demonstrating significant effectiveness.

[0019] Example 3: Unlike Example 1, the clamping plate 4.6 has a rubber buffer pad on the side facing the object being lifted to protect the end of the object being lifted; the sling 3.4 is made of flexible wear-resistant material, and its surface has anti-slip texture or is covered with a rubber layer to increase static friction; the upper center of the lifting beam 1 has a lifting lug 1.1 to facilitate lifting.

[0020] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes that fall within the meaning and scope of equivalents in the content of this invention.
