Description
Technical field
The utility model is related to a kind of self-locking stretching heavy truck correction prosthetic appliance, more particularly to a kind of activity of dual force
Planer-type self-locking stretching heavy truck correction prosthetic appliance.
Background technology
Among current heavy truck crossbeam calibration equipment, the maximum that each king-post is mostly used is 25T pulling force, and one of which is
25T oil cylinders are installed under in king-post body, is above provided with post rod mechanism, post rod mechanism and upper head plate is installed, chain can be pinned,
A kind of external upside-down mounting of king-post has oil cylinder, and the piston rod end of oil cylinder is equipped with roller, walked in two avris of king-post, but they
Two chain rollers are fitted with cylinder, it is a kind of to need to stay in one end padlock of chain when king-post carries out stretching operation
The upper head plate of post rod mechanism, a kind of is that one section of padlock of chain is stayed in into the roller end portions that the piston rod of oil cylinder is equipped with, and is being passed through
Two chain rollers being equipped with king-post body are stretched highly in the up and down of king-post body to adjust, and are remake for vehicle body, right
Vehicle body is repaired, but the general Breadth Maximum of king-post body is 280mm, and chain will enter by two sprocket wheels in 280mm width
Row transformation angle, and the diametric requirements of chain roller are also big, and change gap of such chain between sprocket wheel is small, during chaining bar
It is also noted that chain can not knot in stretching, so chaining bar can very bother difficulty；Again because typically to chain length
Ask long, the weight of chain is just big, therefore not only chaining bar is bothered, and operator will also have very big strength, by two
After the conversion of individual sprocket wheel, the pulling force of vehicle body reparation does not reach set pulling force yet, and single king-post is 25T drawing to the maximum at present
Power, counterweight truck body crossbeam can only carry out slight body distortion and be repaired, and the long breaking load to chain of chain
Intensity requirement is high, have impact on the security of crossbeam calibration equipment when in use, because longer turn of chain when stretching operation with chain
The angle changed is more, and chain is easier to be disconnected.
A further disadvantage is that existing heavy truck corrects the king-post stretching distance length of prosthetic appliance, all row for oil cylinder
Journey, the oil cylinder highest stroke typically used is 360mm, when being repaired to truck, and this stretching travel is far from being enough, is leaned on
It is that stretching a little again again adjusts chain once, another shortcoming is exactly the fixed dress used when king-post is fixed with beam face platform
Put and be generally adopted by plug bolt type fixing device, it is necessary to which hand is held fixing bolt by operating personnel stretches into inside underbody with sense
Feel the nut location for finding landing beam face lower king-post strut, it is tight to carry out plug rotary fixing screw bolt-lock, and because of vehicle body bottom during locking
Gap between portion and landing beam face is less, therefore operating difficulties during locking, and because the own wt of king-post is also very heavy, during locking
Need operator that there is very big strength.
In existing technology, although multiple spot stretching, but each top to bottom, left and right, front and rear can be carried out to the colliding part of vehicle body
The strength of stretching is single, because they are all an independent systems, the weight of itself is heavier, directly pacifies when operation needs
Dress, so installing and using troublesome poeration.
