[0021] Reel body 10, drive shaft end 11, spherical roller bearing 20, bearing seat 30, through cover 40, reducer 50, lifting motor 60, wire rope baffle 70, V-shaped reinforcement seat 80, oil filling hole 91, oil seal 92, shaft end baffle 93. DETAILED DESCRIPTION

[0022] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Please refer to Figure 1 , Figure 1 The utility model is a schematic diagram of a wire rope hoist drum assembly for an electric hoist according to an embodiment of the present invention.

[0024] As shown in the figure, a wire rope lifting drum assembly for an electric hoist includes a drum body 10, a rope guide installed in the middle of the drum body 10, and a wire rope wound around both ends of the rope guide; a driving shaft end 11 installed at both ends of the drum body 10; a bearing seat 40 installed on the driving shaft end 11 through a spherical roller bearing 20, and a through cover 50 is provided on the outside of the bearing seat 40 by screw fixing cover; a reducer 50 connected to the driving shaft end 11 through a key; and a lifting motor 60 installed at the other end of the driving shaft end 11.

[0025] In one embodiment of the present invention, the drum body 10 is used to wind the wire rope to complete lifting and traction. It is provided with a left-hand groove and a right-hand groove. A rope guide is installed without a groove in the middle. The left-hand groove and the right-hand groove are respectively wound with wire rope to complete the fixation. Finally, it is installed on the rope guide and extended downward, and a hook can be installed on the end.

[0026] The drive shaft 11 is mounted on each end of the reel body 10, completing the assembly and drive. Bearing blocks 40 are mounted on each end of the drive shaft 11, cooperating with the spherical roller bearings 20 for rotation. The bearing blocks 40 also seal the spherical roller bearings 20 through the cover 50. A lifting motor 60 drives the drive shaft 11, rotating the reel body 10, while a speed reducer 50 matches the speed and transmits torque.

[0027] Among them, the drum body 10 is installed with a wire rope baffle 70 by bolts. The wire rope baffle 70 is used to tighten the outermost end of the wire rope. When the wire rope is installed, its end needs to be extended into the drum body 10 and then wound onto the surface of the drum body 10. The outermost end of the winding is pressed and locked by the wire rope baffle 70 to enhance the lifting stability and ensure safety.

[0028] The drive shaft end 11 and the reel body 10 are separately located. Specifically, the end cap of the reel body 10 is secured via a V-shaped reinforcement seat 80. The V-shaped reinforcement seat 80 is fitted over and welded to the drive shaft end 11 and features a V-shaped groove with a rectangular groove extending from the bottom for easy positioning. The end cap of the reel body 10 is inserted into the V-shaped groove and welded securely. The two create an interference fit and are then welded securely. The V-shaped groove mitigates the impact of the reel body 10's rotation, reduces deformation, and enhances the stability of the end of the reel body 10.

[0029] In a preferred embodiment, an oil filling hole 91 is installed on the top of the bearing seat 30, and the oil filling hole 91 is connected to the spherical roller bearing 20 to improve the lubrication effect.

[0030] Furthermore, oil seals 92 are provided on both sides of the spherical roller bearing 20 to ensure sealing and prevent leakage of lubricating oil.

[0031] A shaft end baffle 93 is installed between the outer side of the reducer 50 and the end of the drive shaft end 11 of the present invention to protect the shaft end.

[0032] In addition, an electrically connected limit switch is provided on one side of the lifting motor 60 to provide height limit through photoelectric sensing.

[0033] In summary, the utility model connects the drive shaft and the drum body through a V-shaped reinforcement seat, thereby enhancing the stability of the end of the drum body. At the same time, the wire rope baffle locks the bottom wire rope, which can ensure safety and the overall operation is convenient and safe.

[0034] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
