Description

Technical Field

[0001] The utility model relates to the field of lifting equipment, in particular to an automatic rope-arranging winch with self-adaptive rope-entry angle. Background Art

[0002] A winch is a lightweight lifting device that uses a drum wrapped around a wire rope or chain to lift or drag loads. It can operate in vertical, horizontal, or inclined directions. It is a versatile device that can be used independently or as an integral part of other mechanical equipment.

[0003] The rope arrangement assembly of existing winches is fixed relative to the drum, and the rope entry angle is fixed and cannot be adjusted. Even if it is adjustable, it requires manual disassembly and reassembly to adjust it to different working conditions when the hoist is not in the lifting state. Therefore, existing winches cannot adjust the rope entry angle or the operation of adjusting the rope entry angle is cumbersome and requires stopping the machine for adjustment.

[0004] Based on this, the present application provides an automatic rope-arranging winch that can adapt to the rope entry angle to solve the above problems. Utility Model Content

[0027] Embodiment: An automatic rope-arranging winch with self-adaptive rope-entry angle, as shown in the attached Figure 1 To the attached Figure 3 As shown, it includes a base 1, a drum 2, a rope arrangement assembly 3, a bracket 4, a spline sleeve 5, a bearing seat 6, a flange plate 7, a connecting shaft 8, a drive device and a transmission device, wherein:

[0028] A spline sleeve 5 and a connecting shaft 8 are fixedly mounted on both ends of the drum 2, and the spline sleeve, the connecting shaft and the drum are coaxially arranged.

[0029] The spline sleeve 5 and the connecting shaft 8 can be rotatably mounted on a bearing seat 6 (i.e., a seated bearing, UCF208 seated bearing is used in this embodiment) fixed to the inner wall of the base 1. The spline sleeve 5 is used to connect to the driving device, and the connecting shaft 8 is used to connect to the transmission device.

[0030] The two flange plates 7 are fixedly mounted on the outer side of the base 1 with the spline sleeve 5 and the connecting shaft 8 as the axis, and the outer edge of the flange plate 7 is provided with an annular groove 7.1. The width of the annular groove 7.1 in this embodiment is ≥ the thickness of the bracket 4 and is no more than 5 mm greater than the thickness of the bracket.

[0031] The ends of the rope-arranging assembly 3 are respectively mounted on the two brackets 4. The other ends of the brackets 4 are provided with through holes 4.1 that fit into the annular grooves 7.1, allowing the brackets 4 to be rotatably mounted on the flange plate 7. This design allows the brackets to be rotatably mounted on the flange plate. At the same time, the brackets are limited in position by the flange plate and the side walls of the base, ensuring the structural stability of the brackets. This allows the rope-arranging assembly to self-adjust its position according to the rope entry angle. Even if the rope entry angle changes due to changes in the working position during the lifting process, the rope-arranging assembly can still self-adjust its position, thereby reducing the tension in the wire rope.

[0032] The output shaft of the drive device is inserted through the center hole of the flange plate 7 and into the splined sleeve 5. The connecting shaft 8 is connected to the rope arrangement assembly 3 via a transmission mechanism. The drive device utilizes a brake motor, which provides automatic operation of the reel and eliminates the need for a separate brake device on the connecting shaft or splined sleeve. The transmission mechanism utilizes one of a chain drive, a synchronous belt drive, a gear drive, or a belt drive. In this embodiment, a synchronous belt (large and small pulleys + synchronous belt) is used.

[0033] The rope arrangement assembly 3 includes a reciprocating screw 3.1, a positioning shaft 3.2 and a pulley seat assembly 3.3. The two ends of the reciprocating screw 3.1 can be rotatably installed between the two brackets 4. The positioning shaft 3.2 is fixedly installed between the two brackets 4 in parallel with the reciprocating screw 3.1. The pulley seat assembly 3.3 is movably installed on the reciprocating screw 3.1 and the positioning shaft 3.2. The pulley seat assembly includes a sliding seat and a pulley automatically provided on the sliding seat for limiting the wire rope.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
