A horizontal guiding rope passing device for a traction winch

Abstract

The present invention provides a horizontal guiding rope passing device for a traction winch, which mainly consists of a handwheel device, a driving sprocket, a bidirectional lead screw, a copper nut, a horizontal guiding shaft, a slider device assembly, a support seat, a vertical drum, a vertical core shaft, a movable pin shaft, fasteners, etc. Components such as a vertical drum, a vertical core shaft and a copper nut are installed on the slider device assembly. The bidirectional lead screw and the horizontal guiding shaft are installed on the two ends of the support seat. The driving sprocket drives the bidirectional lead screw and the copper nut to drive the slider device assembly to reciprocate on the horizontal guiding shaft, so that the cable is neatly arranged on the drum. One end of the movable pin shaft is fixed to the main body of the slider device assembly by a bolt, and the other end restricts the rope passing position of the cable on the slider device assembly through a swivel bolt and a wing nut. Thus, when the rope loop carried by the cable needs to pass through the middle of the vertical drum, the movable pin shaft can be rotated and opened, so that the rope loop can smoothly pass through the notch on the rear bottom plate of the vertical drum.

Description

Technical Field

[0001] The invention relates to a horizontal guide rope passing device, in particular to a horizontal guide rope passing device for a traction winch, belonging to the technical field of engineering machinery equipment. Background Art

[0002] The rope arrangement device is a commonly used component of the winch, mainly used to arrange the winch cable or wire rope on the drum in an orderly manner. The rope arrangement device is generally equipped with a double guide screw and a guide shaft. The double guide screw is used to drive and support the sliding device assembly, and the horizontal guide shaft is only used to support the sliding device assembly. The cable needs to pass between two vertical drums, and the size of the cable head or rope ring is strictly limited.

[0003] The existing rope arrangement device is only suitable for some conventional ship moving and positioning winches. For some special purpose winches (such as traction winches), due to actual operation needs, the end of the cable needs to have its own rope ring for use when the winch is towing. Because the cable needs to be well arranged on the drum, the gap between the two vertical drums cannot be too large. When the rope ring of the winch cable needs to pass through the rope arrangement device due to operation needs, because the gap between the two vertical drums is generally 1.1 to 1.2 times the diameter of the cable, and the rope ring size is generally 1.5 to 2 times the diameter of the cable, the designer needs to balance between the good arrangement of the cable on the drum and the actual traction needs of the traction winch towing operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a horizontally guided rope passing device for a traction winch that can facilitate the passage of a rope ring, thereby ensuring the horizontal guidance and arrangement of the cable used for the traction winch of an engineering ship, while solving the problem that the rope ring of the cable cannot pass smoothly between two vertical drums.

[0005] The present invention provides a horizontal guide rope passing device for a traction winch, which is used for assisting a cable rope ring to pass smoothly between two vertical drums; a double guide screw and a horizontal guide shaft are installed on support seats at both ends; a slider device assembly is slidably assembled on the double guide screw and the horizontal guide shaft; the double guide screw is rotated by a hand wheel device and / or a transmission sprocket arranged at the end; the double guide screw and a copper nut are driven by the transmission sprocket to drive the slider device assembly to slide back and forth on the horizontal guide shaft, so that the cables are arranged neatly on the drum.

[0006] One end of the movable pin is fixed to the bottom of the slider assembly by bolts, the movable pin spans the rope gap at the bottom of the slider assembly, and the other end of the movable pin is movably assembled at the other end of the rope gap by a movable bolt and a butterfly nut. The size of the specific part of the rope gap is larger than the size of the cable loop. Therefore, when the rope loop of the cable needs to pass through the middle of the vertical drum, the movable pin can be rotated to open so that the rope loop can pass smoothly through the gap of the bottom plate behind the vertical drum.

[0007] As a further technical solution of the present invention,

[0008] Further, the slider device mainly consists of a vertical roller, a vertical mandrel, and a copper nut. The vertical roller is rotationally connected to the bidirectional lead screw through the copper nut. The body of the vertical roller is slidably sleeved with a horizontal guide shaft. A pair of vertical mandrels are installed in the middle of the vertical roller. The cable passes through the middle of the pair of vertical mandrels, and the width of the rope passing notch is greater than the working spacing width between the pair of vertical mandrels.

[0009] Further, one end of the movable pin shaft is fixed to the bottom plate of the vertical roller through a bolt. The movable pin shaft straddles the rope passing notch of the bottom plate of the vertical roller, and the other end of the movable pin shaft is movably assembled to the other end of the bottom plate of the vertical roller through a swivel bolt and a wing nut.

[0010] Further, the rope passing notch is T-shaped, including a transverse notch and a longitudinal notch. The longitudinal notch extends from one side of the bottom plate to the transverse notch in the middle of the bottom plate. The width of the longitudinal notch is less than the working spacing between the pair of vertical mandrels and greater than the size of the cable, and the width of the transverse notch is greater than the size of the cable sheath.

[0011] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects: This design can ensure the traction of the cable while facilitating the passing of the cable loop. This disclosure can be achieved by improving the bottom plate of the existing rope passing device and has commercial use value. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0020] This embodiment provides a horizontal guiding and rope-passing device for a traction winch, which is mainly used for the horizontal guiding and arranging of the cable for the traction winch of an engineering ship, and to solve the problem that the cable loop carried by the cable cannot smoothly pass between two vertical drums 8.

[0021] This device mainly consists of a handwheel device 1, a driving sprocket 2, a bidirectional lead screw 3, a copper nut 7, a horizontal guiding shaft 4, a slider device assembly 5, a support seat 6, a vertical drum 8, a vertical core shaft 9, a movable pin 11, fasteners, etc.

[0022] Components such as the vertical drum 8, the vertical core shaft 9, and the copper nut 7 are installed on the slider device assembly 5. The bidirectional lead screw 3 and the horizontal guiding shaft 4 are installed on the two end support seats 6.

[0023] The driving sprocket 2 drives the bidirectional lead screw 3 and the copper nut 7 to drive the slider device assembly 5 to reciprocate on the horizontal guiding shaft 4, so as to make the cable neatly arranged on the drum.

[0024] One end of the movable pin 11 is fixed to the body of the slider device assembly 5 through a fixing bolt 10, and the other end limits the rope-passing position of the cable on the slider device assembly 5 through a swivel bolt 13 and a wing nut 12.

[0025] Thus, when the cable loop carried by the cable needs to pass through the middle of the vertical drum 8, the movable pin 11 can be rotated and opened, so that the loop can smoothly pass through the notch in the rear bottom plate of the vertical drum 8.
