Abstract
The utility model discloses a one-way mooring rope machine which comprises a rope wheel, a base and a transmission shaft. The base abuts against a rope wheel inner hole in a slewing mode. The transmission shaft abuts against a base inner hole in a slewing mode. Right cam transmission pairs are arranged at the right end of the transmission shaft and composed of a plane cam A and a plane cam B. The plane cam A is installed on the transmission shaft in an axial sliding mode. The plane cam B is arranged in the rope wheel inner hole and the plane cam B can rotate with the rope wheel. The plane cam A abuts against the plane cam B under the effect of a pressure spring. Reverse cam transmission pairs are arranged at the left end of the transmission shaft and composed of a plane cam C and a plane cam D. The plane cam C is installed on the transmission shaft in an axial sliding mode. The plane cam C abuts against the plane cam D under the effect of a pressure spring. The plane cam D is connected with a driving gear. An annular gear is arranged in an inner hole which is formed in the left end of the rope wheel. The driving gear is meshed with the inner gear through an intermediate gear. The one-way mooring rope machine has the advantage that the rope wheel just rotates towards one direction on matter which direction the mooring rope machine is rotated towards.
Description
Technical field
The utility model relates to the hawser machine that a kind of rope sheave only rotates towards a direction.
Background technology
When boats and ships pull in to shore, need to be drawn by hawser, the traction work of hawser is many times completed by manual hawser machine, the direction of the sail that manual hawser machine also should be used for changing on sailing boat, the hawser machine is also used in a lot of workplaces.But, the hawser machine of prior art, the rotation direction of rope sheave is identical with the rotation direction of manual rocking handle, and rope sheave can rotate by both direction, and this often uses in practice and makes troubles.
Summary of the invention
Technical problem to be solved in the utility model is to provide the hawser machine that a kind of rope sheave only rotates towards a direction.
The utility model is implemented by following technical solution:
a kind of unidirectional hawser machine, it is characterized in that: comprise rope sheave, base and transmission shaft, base passes through the outer bearing pivoting support at the rope sheave endoporus, transmission shaft passes through the neck bearing pivoting support at the base endoporus, it is secondary that the right-hand member of transmission shaft is provided with the forward cam drive, forward cam drive pair is comprised of face cam A and the face cam B of end face engagement, face cam A is arranged on transmission shaft and can endwisely slips, face cam B is located at the rope sheave endoporus and rope sheave rotates together, face cam A leans face cam B holding out against under action of the spring, it is secondary that the left end of transmission shaft is provided with reverse cam drive, oppositely the cam drive pair is comprised of face cam C and the face cam D of end face engagement, face cam C is arranged on transmission shaft and can endwisely slips, face cam D pivoting support is outside transmission shaft, face cam C leans face cam D under the Compress Spring effect, face cam D connects driving gear, rope sheave left end endoporus is provided with internally toothed annulus, driving gear is by intermediate gear and internally toothed annulus engagement.The right-hand member of described rope sheave is provided with the rope sheave lid, and the opening of rope sheave lid is provided with top cover, and the right axle head of transmission shaft stretches out outside top cover and manual rocking handle is connected.
The hawser machine of technique scheme, its principle of work is: when the forward rotation transmission shaft, transmission shaft drives face cam A and face cam C forward rotation simultaneously, and face cam A drives face cam B and then drives the rope sheave forward rotation, and this moment, face cam C and face cam D skidded mutually; When the backward rotation transmission shaft, transmission shaft drives face cam A and face cam C backward rotation simultaneously, face cam C drives face cam D and driving gear backward rotation, counter-rotational driving gear drives the rope sheave forward rotation after commutating by intermediate gear, and this moment, face cam A and face cam B skidded mutually.Thus, direction rotating drive shaft whichsoever, rope sheave only can rotate towards a direction, and this brings great convenience for application of hawser machine.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is constructional drawing of the present utility model.
The specific embodiment
Describe details and the principle of work of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
as shown in the figure, unidirectional hawser machine of the present utility model, comprise rope sheave 1, base 3 and transmission shaft 9, base 3 passes through outer bearing 2 pivoting supports at rope sheave 1 endoporus, transmission shaft 9 passes through neck bearing 4 pivoting supports at base 3 endoporus, it is secondary that the right-hand member of described transmission shaft 9 is provided with the forward cam drive, forward cam drive pair is comprised of face cam A and the face cam B of end face engagement, face cam A is arranged on transmission shaft 9 and can endwisely slips, the cylindrical of face cam B is square, corresponding rope sheave 1 endoporus is also square with it, face cam B is set in the rope sheave endoporus and rope sheave 1 rotates together, face cam A leans face cam B holding out against under spring 5 effect, when the transmission shaft forward rotation, face cam A drives face cam B forward rotation, when the transmission shaft backward rotation, produce between face cam A and face cam B and skid, face cam A moves axially compression and holds out against spring, it is secondary that the left end of described transmission shaft 9 is provided with reverse cam drive, oppositely the cam drive pair is comprised of face cam C and the face cam D of end face engagement, face cam C is arranged on transmission shaft 9 and can endwisely slips, face cam D is by the left end spindle nose of bearing 12 pivoting supports at transmission shaft 9, face cam C leans face cam D under Compress Spring 10 effects, when the transmission shaft backward rotation, face cam C drives face cam D backward rotation, when the transmission shaft forward rotation, produce between face cam C and face cam D and skid, face cam C moves axially the compression Compress Spring, face cam D connects driving gear 13(, and both are structure as a whole), rope sheave 1 left end endoporus is provided with internally toothed annulus 11, driving gear 13 is by intermediate gear 15 and internally toothed annulus 11 engagements, intermediate gear 15 rotatably is located on gear wheel shaft 14, gear wheel shaft 14 fixedly mounts on described base 3, the right-hand member of described rope sheave 1 is provided with rope sheave lid 6, and the opening of rope sheave lid 6 is provided with top cover 7, and the right axle head of transmission shaft 9 stretches out outside top cover 7 and manual rocking handle 8 is connected.
The utility model is work like this: when the manual rocking handle of forward rotation, transmission shaft drives face cam A and face cam C forward rotation, face cam A drives face cam B and then drives the rope sheave forward rotation, and this moment, face cam C and face cam D skidded mutually; When the counter rotation manual rocking handle, transmission shaft drives face cam A and face cam C backward rotation, face cam C drives face cam D and driving gear backward rotation, counter-rotational driving gear drives the rope sheave forward rotation after commutating by intermediate gear, and this moment, face cam A and face cam B skidded mutually.Direction rotation manual rocking handle whichsoever, rope sheave only can rotate towards a direction.
