Background technique:
It draws horse to remove and is widely used in rail truck maintenance, mechanical erection, mine maintenance, the support of architectural engineering and general weight
The decline of object raising is outer, is also applied to dismantle the round shape workpiece such as belt pulley, gear, the bearing in various mechanical equipments.
Tradition draws the pulling claw of horse not having positioning function in its pin shaft rotation process, can nature when not by external force
Sagging, this state causes to need manually to control pulling claw, pulling claw is made to be maintained at the position of needs when using horse is drawn
It sets, then rotary lifting screw rod makes pulling claw gradually stress, and the control to pulling claw could be unclamped after stress, is drawn using friction power limit
Horse moves freely.
Therefore, this traditional drawing horse, very inconvenient in use, bigger for some volumes drawing horse just need
More people are wanted to operate.
Utility model content:
The technical problem to be solved by the utility model is to provide a kind of portable orientable in pulling claw rotation process drawings
Horse.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of portable drawing horse, including pushing tow
Screw rod, attachment base is threaded on pushing tow screw rod, and attachment base outer rim is circumferentially evenly equipped with multiple link slots, leads in each link slot
It crosses pin shaft and is rotatably connected to a pulling claw, a delineation position is distributed with along pin shaft is circumferentially discrete at least one side of the pulling claw
Slot, any link slot at least one be provided with an installation opposite with corresponding locating slot on the opposite inner sidewall of locating slot
Hole is connected with the holding screw that can be displaced along the axial elasticity of mounting hole in mounting hole, and the head of holding screw is in elastic force
In the locating slot for driving lower insertion opposite.
As a preferred embodiment, the locating slot is the strip slot to extend radially outwardly along pin shaft.
As a preferred embodiment, multiple extending radially outwardly along pushing tow screw rod are circumferentially evenly equipped on the attachment base
Convex block, the link slot are arranged in correspondingly on each convex block, and the mounting hole is through-hole, and the other end of mounting hole is in convex block
Opening is formed on lateral wall, mounting hole is connected with a screw rod close to the threaded one end on the outside of convex block, is provided with one in mounting hole
Root spring, both ends of the spring are abutted against with screw rod and holding screw respectively.
As a preferred embodiment, the number of the link slot is three, be additionally provided on the attachment base one it is spare
Link slot, the spare link slot are located at the centre of any two link slot, are on same axis with another link slot, the spare company
It is provided with mounting hole on access slot at least side side wall, and one is connected in the mounting hole can be along the axial elasticity position of mounting hole
The holding screw of shifting.
The beneficial effects of the utility model are: by the locating slot in the circumferential uniformly discrete arrangement of pulling claw side setting, and
Setting can be along the holding screw that mounting hole axial elasticity moves, so that pulling claw is during rotation in connection groove sidewall, tightening
Screw can successively cooperate with each locating slot, in holding screw one locating slot of insertion, pulling claw can be prevented to rotate automatically, thus
So that pulling claw is kept its state, realizes the function of positioning in pulling claw rotation process.
Again since locating slot is the strip slot to extend radially outwardly along pin shaft, it is corresponding with holding screw to expand locating slot
Range, it is ensured that when a small amount of positional shift occurs for pulling claw, holding screw, which can be still properly inserted in locating slot, realizes positioning function.
Improve the job stability and reliability described in the utility model for drawing horse.
Again due to being circumferentially evenly equipped with multiple convex blocks to extend radially outwardly along pushing tow screw rod, the link slot on attachment base
It is arranged on each convex block correspondingly, mounting hole is through-hole, is convenient for the installation of holding screw, spring and screw rod, screw rod in this way
Adjustable springs are to the elastic force of holding screw, to adjust holding screw to the stationkeeping ability of pulling claw.
Again due to being additionally provided with a spare link slot on attachment base, two pulling claws of spareslots two sides can be removed, it will
One of them pulling claw removed is installed in spareslots, is formed two pawls and is drawn horse, easily realizes the transformation for drawing horse function.
Detailed description of the invention:
