Problems solved by technology

[0003] As far as the relevant prior art is concerned, the patent case No. CN1907837 of the Chinese Announcement utilizes the cooperation between the cam surface of the clutch handle and the cam surface of the clutch bushing to control the clutch lever to break away from or insert into the brake groove of the internal gear, so as to realize clutch effect, but the design of the double cam surface is likely to cause the degree of coordination between the two to gradually deteriorate due to the long-term contact friction. In this way, the clutch action of the clutch lever relative to the internal gear will inevitably cause Affected, in addition to easily causing inaccurate movements, there may even be problems with clutch failure

Embodiment Construction

[0014] see figure 1 and figure 2 , the winch machine 10 shown in the figure includes a frame 20 , a reel 30 , a drive shaft 40 , and a speed reduction device 50 .

[0015] The drum 30 is rotatably mounted on the frame 20 for winding a steel cable (not shown).

[0016] The drive shaft 40 is rotatably and coaxially installed in the reel 30, and the two ends of the drive shaft 40 extend out of the reel 30 respectively, and one end is connected to a power source (not shown), so that the drive shaft 40 can be driven by the power source to rotate.

[0017] Such as figure 2 and image 3 As shown, the speed reduction device 50 has a casing 51, a sun gear 52, a ring gear 53, and three planetary gears 54. As shown in Figures 2 and 3, the casing 51 is fixed on one end of the frame 20 and has two The opposite limiting hole 512 (actually at least one is enough); the sun gear 52 is arranged in the box body 51 and is connected to the other end of the drive shaft 40, so that the sun ge...

Abstract

An engaging and disengaging device for a winch comprises a rotary knob and an engaging and disengaging assembly. The engaging and disengaging assembly comprises an engaging and disengaging gear, a positioning bolt, an elastic sheet and an elastic piece. A plurality of positioning grooves are formed in the periphery of the engaging and disengaging gear at intervals. The positioning bolt is arranged between the rotary knob and the engaging and disengaging gear in an axially-moving mode. One end of the elastic sheet is fixed to the rotary knob, and the other end of the elastic sheet abuts against the positioning bolt so that the positioning bolt can be pushed towards the engaging and disengaging gear to be plugged into one positioning groove of the engaging and disengaging gear. The elastic piece is arranged on the positioning bolt and used for pushing the positioning bolt away from the engaging and disengaging gear, so that the positioning bolt is disengaged from the positioning groove where the positioning bolt is originally plugged. In this way, the engaging and disengaging effect can be achieved with the simple structural cooperation.

Description

technical field [0001] The invention relates to a winch machine, in particular to a clutch device for the winch machine and a winch machine using the clutch device. Background technique [0002] The winch machine is a kind of effect of pulling the object by using the retracting action of the wire rope. In order to allow the operator to quickly pull the wire rope out of the drum for operation, the winch machine is usually equipped with a clutch device to control the movement of the drum. turn. [0003] As far as the relevant prior art is concerned, the patent case No. CN1907837 of the Chinese Announcement utilizes the cooperation between the cam surface of the clutch handle and the cam surface of the clutch bushing to control the clutch lever to break away from or insert into the brake groove of the internal gear, so as to realize clutch effect, but the design of the double cam surface is likely to cause the degree of coordination between the two to gradually deteriorate due...
