Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a novel electric winch lifting device. Background Technology

[0002] In the field of high-altitude tower operations, traction and hoisting auxiliary equipment are key tools to ensure smooth construction. Currently, this field has developed technical solutions represented by hand-cranked winches and industrial winches, providing basic support for various operational scenarios. Hand-cranked winches, with their portability and independence, are widely used in foundation hoisting tasks; while large electric winches, with their powerful motors, meet the lifting needs of heavy objects. As tower construction develops towards higher efficiency and precision, the industry has placed higher demands on the integration, lightweighting, and environmental adaptability of high-altitude operation equipment, driving the continuous evolution of traction technology towards intelligence and multi-functionality. The existing hoisting devices have the following problems: 1. Low efficiency of purely manual winches: Currently, the hand-cranked winches commonly used in tower operations rely on human power to operate, which requires a continuous output of a large amount of physical strength (especially in scenarios such as pulling cables and adjusting crossarms). When operated by a single person, the pulling speed is slow (usually only 0.5-1 meters per minute), and the components are prone to swaying due to uneven force, increasing the risk of working at height.

[0003] 2. Poor adaptability of large electric winches: Although industrial-grade electric winches have great pulling force, they generally weigh more than 20 kg and are bulky, making them difficult to transport to high-altitude platforms on iron towers (such as working positions 10-30 meters above the ground). They also require external power supply or large generators, which limits their practicality in field iron tower scenarios.

[0004] 3. When the existing hoisting device is not in use, the wire ropes wound on it are prone to loosening due to movement or other reasons. The device lacks a function to prevent the wire ropes from loosening. Therefore, when the device is needed, the wire ropes must be readjusted, which is time-consuming and laborious, thus affecting construction efficiency.

[0005] In summary, the development of this new type of electric winch lifting device is aimed at solving the problems of low efficiency, poor adaptability, and limited functionality of traditional traction tools in high-altitude tower operations. It combines mature portable power technology and mechanical transmission technology to form a targeted and innovative solution, filling the gap in the application of lightweight, convenient, and multifunctional traction tools in high-altitude tower operations. Summary of the Invention

[0006] Therefore, it is necessary to provide a new type of electric hoisting device to address the aforementioned technical problems.

[0007] In order to solve the above-mentioned technical problems, the present invention solves the problems of low efficiency of purely manual winches, poor adaptability to large electric winches, and limited tool functions through the following technical solutions.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A novel electric winch lifting device includes a mounting plate. A U-shaped plate is fixedly mounted on the right side of the mounting plate. Mounting holes are provided at the four corners of the mounting plate. A gear cover is fixedly mounted on the right side of the front side of the inner cavity of the U-shaped plate. A large gear is provided on the right side of the inner cavity of the gear cover. A small gear meshes with the large gear at the lower left. A drive shaft is fixedly installed through the upper middle part of the small gear. The front and rear ends of the drive shaft extend movably through to the outside of the U-shaped plate. A power interface is fixedly mounted at the front end of the drive shaft. An anti-loosening component is installed on the right side of the gear cover. An n-shaped handle is detachably mounted on the front side of the gear cover and the rear side of the U-shaped plate. A rotating rod for winding a steel wire rope is fixedly installed through the upper middle part of the large gear. The front end of the rotating rod is rotatably mounted on the inner wall of the inner cavity of the gear cover, and the rear end of the rotating rod is rotatably mounted on the inner wall of the inner cavity of the U-shaped plate. Winch discs are fixedly sleeved on the outer side of the rotating rod near both the front and rear ends.

[0009] As a preferred embodiment of the present invention, the anti-loosening component includes a straight plate disposed on the right side of the gear cover and a screw threaded through and installed on the straight plate near the middle. The front and rear sides of the straight plate are fixedly installed on the inner wall of the inner side of the n-shaped handle, and an arc-shaped pressure plate is movably installed on the left end of the screw. A limit telescopic rod is fixedly installed on the right side of the arc-shaped pressure plate near the top and bottom.

[0010] In a preferred embodiment of this utility model, a knob is fixedly installed on the right end of the screw.

[0011] In a preferred embodiment of this utility model, a connecting plate is fixedly installed on the right end of each limiting telescopic rod, and the opposite side of the connecting plate is fixedly installed on a straight plate.

[0012] This utility model provides a novel electric winch lifting device. Its mounting plate has mounting holes, allowing for quick and secure fixation to the tower using conventional fasteners such as U-bolts. This facilitates rapid deployment and convenient operation. The design incorporates a large gear, a small gear, and a power interface, enabling both electric and manual assembly via a hand drill and a hand crank, thus creating a dual-power mode. This addresses the issues of traditional electric winches relying on external power and the low efficiency of manual winches. The device utilizes the interplay of components such as a straight plate, screw, knob, arc-shaped pressure plate, limiting telescopic rod, and connecting plate. Rotating the knob drives the screw, which in turn moves the arc-shaped pressure plate linearly to the left, applying a uniform clamping force to the wire rope. This clamping method is simple to operate, provides a secure clamp, prevents rope loosening, and ensures the stability and safety of the lifting operation. Furthermore, the clamping mechanism possesses excellent self-locking properties, further enhancing the anti-loosening effect. Attached Figure Description

[0017] like Figures 1-4 As shown, this embodiment provides a novel electric winch lifting device, comprising: a mounting plate 1, a U-shaped plate 2 fixedly mounted on the right side of the mounting plate 1, mounting holes 3 at the four corners of the mounting plate 1, a gear cover 4 fixedly mounted on the right side of the front side of the inner cavity of the U-shaped plate 2, a large gear 5 disposed on the right side of the inner cavity of the gear cover 4, a small gear 6 meshing with the lower left of the large gear 5, and a drive shaft fixedly mounted through the upper middle part of the small gear 6, the front and rear ends of the drive shaft respectively extending movably through to the outside of the U-shaped plate 2, a power interface 7 fixedly mounted on the front end of the drive shaft, the power interface 7 being a hexagonal slot + spring lock structure, enabling rapid assembly of a 20V lithium battery electric drill, and also serving as a hand crank interface, forming an electric-manual dual power mode, solving the problems of traditional electric winches relying on external power and low efficiency of manual winches. When the electric drill is out of power or malfunctions, a folding hand crank handle (40cm unfolded length) can be connected, and the drive wheel can be manually rotated, using the lever principle to reduce the hand cranking force to 30- 50N ensures normal operation in emergency scenarios.

[0018] An anti-loosening component 8 is installed on the right side of the gear cover 4, and an n-shaped handle 9 is detachably installed between the front side of the gear cover 4 and the rear side of the U-shaped plate 2. A rotating rod 10 is fixedly installed through the middle of the large gear 5. A steel wire rope is sleeved on the outside of the rotating rod 10, and the front end of the rotating rod 10 is rotatably installed on the inner wall of the inner cavity of the gear cover 4, and the rear end of the rotating rod 10 is rotatably installed on the inner wall of the inner cavity of the U-shaped plate 2. A winch wheel 20 is fixedly sleeved on the outside of the rotating rod 10 near both the front and rear ends.

[0019] The anti-loosening component 8 includes a straight plate 81 located on the right side of the gear cover 4 and a screw 82 threaded through the straight plate 81 near the middle. The front and rear sides of the straight plate 81 are fixedly installed on the inner wall of the n-shaped handle 9. An arc-shaped pressure plate 83 is movably installed on the left end of the screw 82.
