Description

Technical Field

[0001] The utility model belongs to the technical field of ship-borne davit winches, in particular to a sling self-adaptive guiding and releasing winch system of a ship-borne davit. Background Art

[0002] The winch is an indispensable lifting and towing power equipment for the ship-borne davit. In order to prevent the sling from coming off the wheel when it is unwinding from the drum and to take into account the guiding function of the sling release, a guide component is generally installed on the cable outlet side of the drum. The existing guide components are mainly rope pressure (such as rope pressure plates) and rope support (such as pulleys). When the rope is gradually lifted, a drag angle is formed between the rope and the guide component, which can easily cause destructive wear of the rope, and the degree of wear is relatively large, affecting the safety of lifting. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a sling adaptive guiding release winch system for a ship-borne davit, which is guided by a sling guide cylinder that can be driven to swing when the sling is released, limits the sling anti-slip wheel, and reduces the dragging friction between the sling and the sling guide cylinder, thereby reducing the wear of the sling.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a ship-borne davit cable adaptive guide release winch system, including a reduction gearbox having a speed limiting clutch, the power input end of the reduction gearbox being connected to the motor, and the power output end being connected to the cable drum; a cable adaptive guide is provided at the cable outlet side of the corresponding cable drum, the cable adaptive guide includes a cable guide cylinder that is laterally swingably arranged in a drum frame, and when the cable wound on the cable drum passes through the cable guide cylinder and is released, the cable drives the cable guide cylinder to swing in the lateral direction.

[0005] Furthermore, a swing shaft is connected to the cylinder side of the cylinder rack, and the cylinder rack is movably connected to the cylinder rack via the swing shaft.

[0006] Furthermore, the sling adaptive guide includes a mounting frame connected to the outer wall of the reduction gearbox, and the drum frame is rotatably mounted on the mounting frame through a rotating shaft. The rotation of the rotating shaft drives the mounting frame to rotate and adjust the inclination angle α of the sling guide drum on the drum frame, so that the sling guide drum is in a horizontal or inclined upward posture with an inclination angle α from the inlet to the outlet.

[0007] Furthermore, the value range of the tilt angle α includes 0° and an acute angle.

[0008] Furthermore, an angle adjustment driving part and a braking part are installed on the mounting frame. The angle adjustment driving part drives the connecting shaft, and the braking part is set to open and hold the brake corresponding to the shaft.

[0009] Furthermore, a plurality of balls distributed in a circumferential array are freely rollingly embedded in the inner cylinder wall of the sling guide cylinder.

[0010] Furthermore, the inlet and outlet of the sling guide cylinder are both rounded to form a rounded structure.

[0011] Beneficial effect: The utility model guides through the sling guide cylinder that can be driven to swing when the sling is released, so that the sling guide cylinder follows the release path of the sling part on the sling drum and swings, eliminating the situation where the sling is prone to form a drag angle with the guide component when it comes out of the drum, thereby achieving the goal of reducing the dragging friction between the sling and the sling guide cylinder while limiting the sling anti-slip wheel, reducing the wear of the sling and ensuring the safety of ship-borne boat crane operations.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] As attached Figure 1 and attached Figure 2 As shown, the cable adaptive guiding release winch system of the ship-borne davit includes a reduction box 1, the reduction box 1 has a speed limiting clutch 2, the power input end of the reduction box 1 is connected to the motor 3, and the power output end is connected to the cable drum 4; it is characterized in that: a cable adaptive guide 6 is arranged corresponding to the cable outlet side of the cable drum 4, the cable adaptive guide 6 includes a cable guide cylinder 10 which is arranged in a drum frame 8 for transverse swinging, and when the cable 7 wound on the cable drum 4 passes through the cable guide cylinder 10 and is released, the cable 7 drives the cable guide cylinder 10 to swing in the transverse direction. The utility model guides the sling guide cylinder 10 which can be driven to swing when the sling 7 is released, so that the sling guide cylinder 10 follows the release path of the sling portion on the sling drum 4 and swings accordingly, eliminating the situation where the sling is easily dragged with the guide component when the sling is unloaded from the drum, thereby achieving the goal of reducing the dragging friction between the sling 7 and the sling guide cylinder 10 while limiting the sling anti-slip wheel, reducing the wear of the sling, and ensuring the safety of the ship-borne boat crane operation.

[0018] As attached Figure 1As shown, the other output end of the reduction gearbox 1 is connected to a cable drum 5 coaxial with the sling drum 4, and the cable of the remote control system of the davit is wound on the cable drum 5.

[0019] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, the drum side of the drum frame 8 is connected with a swing shaft 9, and the drum frame 8 is movably connected to the drum frame 8 through the swing shaft 9. The sling adaptive guide 6 includes a mounting frame 13 connected to the outer box wall of the reduction box 1, and the drum frame 8 is rotatably mounted on the mounting frame 13 through a rotating shaft. An angle adjustment drive unit 11 and a brake unit 12 are installed on the mounting frame 13. The angle adjustment drive unit 11 drives and connects the rotating shaft, and the brake unit 12 corresponds to the opening and closing of the rotating shaft. Among them, the angle adjustment drive unit 11 is preferably a servo motor, and the brake unit 12 is an electric brake. The rotation of the rotating shaft drives the mounting frame 13 to rotate and adjust the inclination angle α of the sling guide drum 10 on the drum frame 8, so that the sling guide drum 10 is horizontal or inclined upward from the inlet 10a to the outlet 10b. More specifically, the value range of the inclination angle α includes 0° and an acute angle. 0° corresponds to the horizontal posture of the sling guide cylinder 10, and the acute angle corresponds to the inclined upward posture of the sling guide cylinder 10. The above two postures of the sling guide cylinder 10 can meet the requirements of the routing direction of the sling 7. However, since the routing of the sling 7 on the lifting arm of the davit is generally inclined upward, the working condition of adjusting the sling guide cylinder 10 to an inclined upward posture is more widely used. The specific inclination angle can be flexibly adjusted according to the actual on-site operation conditions.

[0020] In order to reduce the wear of the sling 7 when entering and exiting the cylinder, the inlet 10a and the outlet 10b of the sling guide cylinder 10 are both rounded to form a rounded structure.

[0021] At the same time, in order to reduce the wear of the sling 7 when passing through the inner cavity of the cylinder, a plurality of balls 14 distributed in a circumferential array are freely rolled and embedded in the inner cylinder wall of the sling guide cylinder 10.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
