Abstract

The utility model relates to a thruster design field discloses a mousing -hook three -jaw draws horse, including drawing horse seat, ejector pin and three claw arm, each claw arm articulates with drawing the horse seat mutually, the ejector pin sets up in drawing horse seat center, tight beam hole has been offered on each claw arm in the same position respectively, be provided with the tight piece of restrainting in the tight beam hole, tight the tight beam hole and the end -to -end connection that pass in proper order on the three claw arm of restrainting carries out tight shu huan. The mode of this staple bolt formula mousing -hook three -jaw draws horse through setting up the staple bolt is tightly restrainted the claw arm to prevent that it from the unhook phenomenon appearing.

Description

Mousing-hook Three-claw pull-horse

Technical field

This utility model relates to thruster design field, especially a kind of Three-claw pull-horse.

Background technology

Drawing horse is instrument commonly used in flight-line maintenance, is mainly used to tear the bearing of damage, belt pulley etc. from axle vertically open Unload down.Draw horse to distinguish with pawl arm quantity, mainly have two pawls to draw horse and Three-claw pull-horse two kinds.Comparatively speaking, Three-claw pull-horse stress Stability is higher but is because it and has three pawl arms, therefore can not be connected by two pawl arms in case anti-avulsion as two pawls draw horse , after long-term use, easily there is unhook phenomenon in hook.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of mousing-hook Three-claw pull-horse, and it can effectively prevent Three-claw pull-horse Break off relations.

Mousing-hook Three-claw pull-horse disclosed in this utility model, including drawing horse seat, push rod and three pawl arms, described each pawl arm with draw horse Seat is hinged, and described push rod is arranged at La Mazuo center, and described each pawl arm offers tight beam hole in same position respectively, described Being provided with tight bundle in tight beam hole, described tight bundle sequentially passes through the tight beam hole on three pawl arms and head and the tail connection carries out bundling ring.

Preferably, described tight bundle is iron wire.

Preferably, described tight beam hole is string configuration, and described tight bundle is anchor ear.

Preferably, described push rod offering screw thread, described push rod is threadeded with drawing horse seat.

Preferably, described push rod rear end offers through hole, is coated with handlebar in described through hole.

Preferably, described push rod rear end connects hydraulic cylinder.

The beneficial effects of the utility model are: pawl arm, by the way of arranging bundling ring, is tightly restrainted by this mousing-hook Three-claw pull-horse, Thus prevent it from unhook phenomenon occurring.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Reference: draw horse seat 1, push rod 2, pawl arm 3, tight beam hole 4, tight bundle 5, handlebar 6.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further illustrated.

As it is shown in figure 1, disclosed mousing-hook Three-claw pull-horse of the present utility model, including drawing horse seat 1, push rod 2 and three pawl arms 3, Described each pawl arm 3 is hinged with drawing horse seat 1, and described push rod 2 is arranged at horse seat 1 center of drawing, identical bits on described each pawl arm 3 Putting and offer tight beam hole 4 respectively, be provided with tight bundle 5 in described tight beam hole 4, described tight bundle 5 sequentially passes through three pawl arms Tight beam hole 4 head and the tail connection on 3 carry out bundling ring.

During use, after pawl arm 3 catches on bearing or the belt pulley of wanted drawing, by securing member, pawl arm 3 is fastened, So can effectively prevent and draw horse unhook phenomenon.

The effect of described tight bundle 5 is to fasten pawl arm 3, and it can select the material such as belt, iron wire, and conduct A kind of optimal way, described tight beam hole 4 is string configuration, and described tight bundle 5 is anchor ear.Anchor ear stability is higher, permissible Reuse.

Draw horse generally to have hydraulic pressure, the type of drive such as electronic and manual, and as a kind of optimal way, described push rod 2 offers Screw thread, described push rod 2 is threadeded with drawing horse seat 1.For convenience of rotating push rod 2, described push rod 2 rear end offers through hole, Handlebar 6 it is coated with in described through hole.And as another kind of optimal way, described push rod 2 rear end connects hydraulic cylinder.
