After assembling is installed, then integral installation carries out arm each the arm of autocrane on automobile chassis Kind performance test.If but find that lower vehicle hydraulic system, arm assembling is unqualified, slide position is improper and flexible rope rate of tension Situations such as improper, is required to dismantle arm again, and the dismounting of arm is very cumbersome, not only increases the production of crane Time, but also can waste a lot of manpower and material resources, seriously affect the progress of normal production.
Authorization Notice No. is that the patent document of CN2802493Y discloses a kind of universal tester for hanging arm of vehicle hoister, should Testing machine includes movable part and fixed part, and fixed part includes sectional shelf-unit, and sectional shelf-unit, which is equipped with, passes through lead screw transmission The lower end motor of connecting combined bracket, there are two two short axles for being installed on after arm in hinge joint, examinations for sectional shelf-unit tool Two short axles when testing are inserted into the rear hinge joint of arm to the assembling for completing arm, can be carried out after being completed to each of arm Class is tested.
Since above-mentioned universal tester for hanging arm of vehicle hoister is using two short axles, two short axles carry out arm outstanding branch, It then needs to replace short axle with the other types arm of different size hinge hole to produce, and in order to make two short axles Outstanding branch can undertake the gravity of arm, need short axle being secured firmly on sectional shelf-unit, and it is cumbersome that this just replaces short axle; In addition, for short axle is secured firmly on sectional shelf-unit, need to set corresponding ruggedized construction so that the structure of sectional shelf-unit compared with For complexity, production cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of Car Crane Retractable Arms experimental rig, to solve to adopt in the prior art Installing arm with two short axles causes to replace the technical issues of short axle is more troublesome.
To achieve the above object, Car Crane Retractable Arms experimental rig provided by the utility model uses following technical side Case:A kind of Car Crane Retractable Arms experimental rig, it is described including being used for support assorted using to support the installation pedestal of arm Installation pedestal includes two installing plates, and experimental rig further includes at least two for the corresponding various support shaft for inserting different thicknesses Mounting hole group, each mounting hole group includes two and is divided on corresponding installing plate and the mounting holes of corresponding perforation.
The beneficial effects of the utility model are:At least two mounting hole groups can insert the various support shaft of different thicknesses, Compared with prior art, the design of at least two mounting hole groups meets the installation requirements of different arms;By the way of inserting The dismounting for making support shaft is more convenient, improves the removal efficiency of arm;Each mounting hole group is divided into corresponding including two Mounting hole on installing plate so that support shaft can keep stress balance in the case where undertaking arm gravity, not need to carry out It reinforces, so that installation pedestal structure is simpler.
The upper edge of the installing plate is bevel edge, and at least two mounting holes set on same installing plate are oblique along being parallel to The extending direction on side is sequentially arranged.In the installation process of arm, which reduces installing plate upper edge to arm Shielded area so that arm is easier to look for hole when mounted and is directed at inserting support shaft.
The installation pedestal is equipped with the fixed part for fixing on the ground.Installation pedestal is fixed on bottom surface to prevent Arm moves during installation and experiment.
The fixed part is the fixation steel plate of installation pedestal bottom welding.
The bottom of the stent is equipped with walking mechanism to adapt to the arm of different length.Stent can move to adapt to difference The length of arm.
The walking mechanism includes the pulley that the frame bottom is equipped with.
The walking mechanism further includes the guide rail for being set along arm in the extending direction of floor projection, on the guide rail Guiding movement is provided with the pulley.It is slidably matched using the guiding of pulley and guide rail, further prevents arm in experiment process In shake.
Two installing plate parallel interval arrangements of installation pedestal, installation pedestal further includes horizontal between two installing plates To reinforcing plate.Lateral strengthening version can effectively prevent arm to shake while arm gravity is undertaken.
