Electric winches usually rely on the vehicle's own power system or an external power supply. They have the advantages of easy operation and high efficiency and are more common in daily life.

[0003] Prior art includes a utility model with a publication number of CN213112316U, which discloses an electric winch comprising a frame, a rope-arranging device mounted on the frame, and a speed-regulating motor.

[0004] During the use of electric winches, it was found that during the operation of the electric winch, since the electric winch is generally used in conjunction with a motor, the entire electric winch equipment is likely to have a large mass, which will cause the problem of not being able to conveniently transport the entire electric winch equipment. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during the operation of the electric winch, the electric winch is generally used in combination with a motor, which easily leads to the disadvantage that the entire electric winch equipment is heavy and cannot be conveniently transported.

[0006] In order to solve the above technical problems, the utility model provides an easy-to-transfer electric winch, including: a mounting frame and a transmission mechanism, a winch shaft is installed on one side of the surface of the mounting frame, a servo motor is installed on the end of the mounting frame away from the winch shaft, the winch shaft is connected to the servo motor by means of a transmission mechanism, a lifting rope is wrapped around the arc surface of the winch shaft, and a transfer mechanism is provided on both sides of the lower surface of the mounting frame, the transfer mechanism includes two transfer frames, the upper ends of the two transfer frames are rotatably connected to the lower surface of the mounting frame, the inner wall of the transfer frame is rotatably connected to a rotating column, the inner wall threads of the two rotating columns are penetrated by the same driving rod, the bottom end of the transfer frame is fixedly connected to a rotating frame, the inner wall of the rotating frame is rotatably connected to a pulley, and two support plates are fixedly connected to the position of the lower surface of the mounting frame corresponding to the transfer frame, and the two support plates are respectively located on both sides of the transfer frame.

[0007] The effect achieved by the above components is: when operating the electric winch, the entire electric winch needs to be moved. Since the usual electric winch is heavy and inconvenient to move, the transfer mechanism provided on the lower surface of the mounting frame can be used to move the position of the pulley in the transfer frame, thereby allowing the entire electric winch to move, and then use the support plate to support and limit it.

[0008] Preferably, one end of the driving rod is fixedly connected to a rotating shaft, and the cross-sectional size of the rotating shaft is adapted to the cross-sectional size of the driving rod.

[0009] The effect achieved by the above components is that when the driving rod is rotated, auxiliary operation can be performed with the help of the rotating shaft fixed on one side of the driving rod.

[0010] Preferably, the cross section of the support plate is L-shaped, and a plurality of friction grooves are provided on the lower surface of the support plate.

[0011] The effects achieved by the above components are: the support area can be increased by the support plate with an "L"-shaped cross section, and the friction groove can be used to increase friction, thereby improving the stability of the entire mounting frame support.

[0012] Preferably, a protective sleeve is fixedly connected to the arc surface of the pulley, and the protective sleeve is a rubber sleeve.

[0013] The effect achieved by the above components is: the pulley can be protected by the rubber protective cover to prevent the pulley from sliding and being damaged.

[0014] Preferably, a limiting mechanism is provided at a position on the surface of the mounting frame corresponding to the winch shaft, and the limiting mechanism includes a guide rail, the lower surface of the guide rail is fixedly connected to the surface of the mounting frame, the inner wall of the guide rail is slidably connected with a slider, the upper surface of the slider is fixedly connected with a fixing ring, the inner wall of the fixing ring is provided with an inlay groove, the inner wall surface of the inlay groove is rotatably connected with a rotating ring, and the rotating ring slides through the inner wall of the fixing ring and the surface of the lifting rope.

[0015] The effect achieved by the above components is: when operating the entire winch shaft, it is necessary to limit the winding of the rope wrapped around the surface of the winch shaft. At this time, the fixed ring and the rotating ring in the limiting mechanism can be used for auxiliary operation, which is convenient for limiting the position of the rope during stretching and winding.

[0016] Preferably, a squeeze rod is threaded through the arc surface of one side of the fixed ring, and one end of the squeeze rod abuts against the surface of the rotating ring. The above component achieves the effect that after the position of the rotating ring is rotated and adjusted, the squeeze rod can be used to fix the position of the rotating ring to prevent it from sliding.

[0017] Preferably, the rotating ring and the fixed ring are both carbide rings, and the cross-sections of the rotating ring and the fixed ring are "C"-shaped.

[0018] The above components have the following effects: the fixed ring and the rotating ring, which have a C-shaped cross section and are made of hard alloy, can be used conveniently.

[0019] Compared with the related art, the easy-transfer electric winch provided by the present invention has the following beneficial effects:

[0020] The utility model provides an easy-to-transfer electric winch. When the electric winch is operated and used, the entire electric winch needs to be transported. Since the conventional electric winch is heavy and inconvenient to move, the transfer mechanism provided on the lower surface of the mounting frame can be used to move the position of the pulley in the transfer frame, so that the entire electric winch can be moved. During this process, the rotating shaft at one end of the driving rod can be rotated first, and then the driving rod will adjust the position of the position with the help of the rotating column in the transfer frame, thereby effectively utilizing the pulley to move the position, and then the support plate is used for support and limiting. By operating the adjusting device, the position of the entire mounting frame can be moved, which facilitates the matching of the servo motor, the transmission mechanism and the winch shaft on the surface of the entire mounting frame.

[0021] When operating the entire capstan shaft, it is necessary to limit the reeling of the rope wrapped around the surface of the capstan shaft. At this time, the fixed ring and the rotating ring in the limiting mechanism can be used for auxiliary operation. The rope is placed on the inner wall of the fixed ring and the embedded ring. When the rope is stretched and collected, the rope will slide horizontally along the guide rail with the help of the slider at the bottom of the fixed ring. By operating the auxiliary device, it is convenient to limit the position of the rope during stretching and reeling. BRIEF DESCRIPTION OF THE DRAWINGS

The arc surface of the pulley 48 is fixedly connected with a protective sleeve 49, which is a rubber sleeve;

[0031] In the embodiments of the present invention, please refer to Figure 4 The limiting mechanism 5 includes a guide rail 51, the lower surface of the guide rail 51 is fixedly connected to the surface of the mounting frame 1, the inner wall of the guide rail 51 is slidably connected to a slider 52, the upper surface of the slider 52 is fixedly connected to a fixing ring 53, the inner wall of the fixing ring 53 is provided with an inlay groove 54, the inner wall surface of the inlay groove 54 is rotatably connected to a rotating ring 55, the rotating ring 55 slides through the inner wall of the fixing ring 53 and the surface of the hanging rope 7, one side of the fixing ring 53 is threaded with an extrusion rod 56, one end of the extrusion rod 56 abuts against the surface of the rotating ring 55, the rotating ring 55 and the fixing ring 53 are both carbide rings, and the cross-section of the rotating ring 55 and the fixing ring 53 is "C"-shaped;

[0032] The working principle of the easy-to-transfer electric winch provided by the present invention is as follows: when the electric winch is operated and used, the entire electric winch needs to be moved, and the rotating shaft 44 at one end of the driving rod 43 is rotated first, so that the driving rod 43 drives the movement of the rotating column 46 in the transfer frame 45.

[0033] When the position limit adjustment is performed for the stretching and collection of the lifting rope 7 wrapped around the surface of the capstan shaft 2, the rotating ring 55 in the fixed ring 53 is first rotated along the inlay groove 54 to align the opening of the fixed ring 53 with the opening of the rotating ring 55. Then, the lifting rope 7 is placed in the rotating ring 55, and then the rotating ring 55 is rotated. At the same time, the surface of the rotating ring 55 is squeezed and fixed with the help of the squeezing rod 56. At this time, the entire rotating ring 55 and the fixed ring 53 cannot continue to deflect in position. Later, when the lifting rope 7 is pulled, the lifting rope 7 will drive the entire fixed ring 53 to move horizontally along the guide rail 51 with the help of the slider 52 fixed at the bottom.
