Description
TECHNICAL FIELD
[0001] The present application relates to the mechanical field, and in particular to a transverse rope-out winch. BACKGROUND
[0002] The winch is mainly used for winding and unwinding the steel wire rope to lift heavy objects. The steel wire rope of the general winch is perpendicular to the direction of the winding drum. The first guide sheave after the winding drum is far away from the winding drum, and the included angle between the steel wire rope and the winding drum is small when the steel wire rope enters or exits the winding drum. Therefore, the general winch can not be equipped with a rope arranging mechanism or can be equipped with a simple rope arranging mechanism.
[0003] However, the general winch needs to keep a long length of the steel wire rope in the vertical direction after the steel wire rope is unwound, so that the steel wire rope can not jump out of the rope groove when entering or exiting the winding drum. The long distance in the unwinding direction cannot be used in the case of insufficient space, and the existing winding drum rope arranging mechanism is in the form of trapezoidal thread sliding friction, which has large friction resistance and cannot withstand large transverse force. Therefore, the steel wire rope guided by the rope arranging mechanism can only be unwound vertically to the rope arranging mechanism, and cannot be unwound parallel to the rope arranging mechanism. SUMMARY

[0019] In some optional embodiments of the present invention, the cable guide is a combination of three cylinders and an arc surface, which can ensure the wire rope exits at multiple directions, including axial forward and backward, downward, and oblique downward.
[0020] In some alternative embodiments of the present invention, the transverse rope-out winch further includes a device base;

Detailed Implementation
[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0036] like Figures 1-8 As shown in the embodiment of the present invention, a transverse rope-exit winch is provided, which mainly includes a reducer 1, a motor 2, a coupling 3, a main shaft 4, a large sprocket 5, a self-aligning roller bearing assembly 6, a drum assembly 7, a ball screw 8, a small sprocket 9, a double-row tapered roller bearing assembly 10, a guide cable box 11, a drum base 12, a brake assembly 13, a guide pulley 14, a cable guide 15, a wire rope 16, a control assembly 17, a device base 18, and a chain 19.
[0037] The drum assembly 7 is a straight cylindrical body with rope grooves for winding the steel wire rope 16. The two sides of the drum assembly 7 are circular webs, which are fixed to the drum by positioning pins and bolts. A square connecting hole is opened in the middle of the web.
[0038] The main shaft 4 is a long, stepped shaft with two square steps in the middle, which are used to mate with the square connecting holes of the web plate. The main shaft 4 is connected to the drum assembly 7 through the square connecting holes.
[0039] Self-aligning roller bearing assemblies 6 are arranged on both sides of the main shaft 4 to support the rotation of the main shaft 4, and the bearing housing is fixed on the drum base 12.
[0040] One end of the main shaft 4 is equipped with a large sprocket 5, a coupling 3, a reducer 1 and a motor 2, which are used to drive the rotation of the main shaft 4. The other end of the main shaft 4 is equipped with a brake assembly 13, which is used to brake the drum assembly 7.
[0041] The guide cable housing 11 is a welded housing with a guide pulley 14 installed in the middle and a ball screw nut installed on the upper part of the housing. One end of the screw that mates with the ball screw nut passes through the drum base 12 and is fixed to the drum base 12 by a double-row tapered roller bearing assembly 10. A small sprocket 9 is installed at the front end of the ball screw 8, and the small sprocket 9 is aligned with the large sprocket 5. The large sprocket 5 transmits the rotational power of the drum assembly 7 to the small sprocket 9 on the ball screw 8 through a chain 19. The small sprocket 9 drives the ball screw 8 to rotate, and the ball screw nut of the ball screw 8 rotates. The nut of the ball screw 8 drives the guide cable housing to move along the guide rail on the drum base 12.
[0042] The control component 17 controls the rotation of the motor 2 and the braking of the braking component 13.
[0043] Based on the transmission ratio determined by the pitch of the drum assembly 17 and the lead of the ball screw 8, the number of teeth of the large sprocket 5 and the small sprocket 9 are determined to ensure that the axial movement speed of the wire rope 16 discharged by the drum assembly 7 is the same as the axial movement speed of the guide cable box 11 driven by the ball screw 8. This ensures that the wire rope 16 is evenly arranged on the rope groove of the drum assembly 7 as the guide cable box 11 moves.
[0044] The guide pulley 14 guides the wire rope 16 that is led out from the guide cable box 11 back into the cable guide 15. The cable guide 15 is a combination of three cylinders and one arc surface, which can ensure the wire rope 16 exits at multiple directions such as axial forward and backward, downward, and oblique downward.
[0045] All components are mounted on the device base 18, which is fixed to the ground foundation by anchor bolts.
[0046] The working principle of the transverse rope winch is as follows: When it is necessary to lift or lower goods, the control component is activated. The control component controls the brake component to release the brake, and the motor is started simultaneously to rotate in both directions. The motor drives the reducer, coupling, main shaft, and drum assembly to rotate in both directions to wind up and unwind the wire rope on the drum assembly. The main shaft synchronously drives the large sprocket on the main shaft to rotate. The large sprocket drives the small link on the ball screw to rotate through the chain. The small sprocket drives the lead screw of the ball screw to rotate. The rotation of the lead screw pushes the nut of the ball screw to move along the lead screw axis. The nut of the ball screw is fixed on the guide cable box, which drives the guide cable box to move along the lead screw axis. The guide cable box drives the guide pulley in the box to move along the lead screw axis. The wire rope from the drum assembly is guided by another guide pulley on the base of the guide pulley in the guide cable box. The other guide pulley leads the wire rope out through the cable guide. Finally, the wire rope is connected to the goods to be lifted or unwound.
[0047] Because the guide pulley in the guide cable box always moves along the axis of the ball screw according to the rotation of the drum assembly, the wire rope being wound and released by the winch can be evenly arranged in the rope groove of the drum assembly.
[0048] When a stop is required, the control unit controls the motor to stop rotating, and simultaneously activates the braking unit to brake the main shaft. The main shaft then drives the drum assembly to stop rotating, and the wire rope stops winding and unwinding.
[0049] The winch in the above embodiment can be arranged in a confined space, allowing the winch wire rope to exit laterally. The rope arrangement mechanism moves the guide box via a lead screw, ensuring that the wire rope is always evenly arranged in the drum grooves and will not jump out of the grooves. The rope arrangement structure uses a ball screw, which has low rolling friction resistance and can withstand lateral forces, thus allowing the wire rope to exit laterally along the drum.
[0050] This invention has been successfully applied to a winch at a ship lock that requires a lateral rope extension direction, and has achieved excellent results. This invention can be extended to other similar applications such as winches that require a lateral rope extension direction in confined spaces.
