Detailed Description

An embodiment of a portable winch mechanism according to the present invention is further described with reference to fig. 1 to 4.

A portable winch mechanism comprises two outer plates 1 and a shell 17, wherein the two outer plates 1 are connected with the shell 17 through a plurality of bolts 10, a gear blocking shaft 2, a ratchet shaft 13, an idler shaft 12 and a large gear shaft 11 which are parallel to each other are rotatably arranged between the two outer plates 1, the gear shaft 2 is provided with gear teeth 14, a torsion spring 15 is arranged between the outer plate 1 and the gear shaft 2, the gear 14 and the ratchet shaft 13 are provided with a ratchet wheel 5 matched with the gear 14, the ratchet shaft 13 is provided with a pinion 3, the big gear shaft 11 is provided with a big gear 8, the idle gear shaft 12 is provided with an idle gear 6 meshed with the big gear 8 and the small gear 3, a friction clutch 4 is arranged at the ratchet wheel 5 and the pinion 3, a wire wheel 9 fixed with a bull gear 8 is arranged on the bull gear shaft 12, a rope is wound on the wire wheel 9, and one ends of the gear blocking shaft 2 and the ratchet shaft 13 extend out of the outer plate 1 and are provided with connectors 16.

When the rope is used, the rope is fixed on the wire wheel 9, when the rope needs to be placed, the gear blocking shaft 2 rotates anticlockwise through the connector 16 by using a wrench, when the gear blocking 14 is staggered with the ratchet wheel 5, the ratchet wheel 5 is not clamped by the gear blocking 14 any more, therefore, the rope can be stretched freely, when the length of the rope is proper, the wrench is loosened, the gear blocking shaft 2 can mesh the gear blocking 14 with the ratchet wheel 5 under the action of the torsion spring 15, and the friction clutch 4 is in a working state, so that the ratchet wheel 5 stops rotating due to the blocking of the gear blocking 14, the ratchet wheel 5 is locked, the rope cannot be stretched continuously, and the winch stops working.

When receiving the rope, use the spanner with 5 axles of ratchet clockwise rotations, friction clutch 4 is because the rotatory drive of ratchet axle 13, make friction clutch 4 stagger, friction clutch 4 stop work, ratchet axle 13 gives pinion 3 with power transmission, pinion 3 passes through idler 6 with power transmission to gear wheel 8, because gear wheel 8 is together fixed with line wheel 9, so line wheel 9 direction of rotation and gear wheel 8 unanimous clockwise rotation play the effect of receiving the line, wherein because the principle of ratchet 5 mechanism when 5 axles clockwise rotation of ratchet, the fender tooth can not block ratchet 5 and rotate, thereby the realization need not motor drive and can use the capstan winch, overall structure is small and exquisite to dismantle conveniently, use occasion is extensive.

The preferred idler shaft 12 of this embodiment is provided with a tensioning device 7 for tensioning the rope, which prevents the rope from being untightened and knotted by winding the rope around the tensioning device 7.

The present embodiment preferably further comprises a bracket, wherein the bracket is provided with a first pin hole, and the bottom of the outer plate 1 is provided with a second pin hole 28 matched with the first pin hole, so that the winch can be fixed on the bracket.

The preferred support of this embodiment includes extension pipe 18, side pipe 27, main part 20 and the person in charge 21 of connecting through round pin axle 19, the top of the person in charge 21 is connected with connecting device 22, connecting device 22's one end is connected with push pipe 23, push pipe 23's one end is equipped with first pipe 24, and overall structure is connected by round pin axle 19, and it is convenient to dismantle, and the bottom is connected and is "worker" word and make the support chassis more stable.

The extension tube 18 and the side tube 27 are preferably provided with anchor screws 26 for adjusting the extension tube 18 and the side tube 27 to be horizontal.

In the preferred embodiment, a threaded strut 25 is disposed between the main pipe 21 and the top pipe 23, and the threaded strut 25 mainly plays a role of supporting the top pipe 23, so as to prevent the top pipe 23 and the head pipe 24 from collapsing due to an excessive stress on the rope.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
