Description
Technical field
A kind of direct selling square tube lock-in techniques apparatus field is the utility model is related to, it is more particularly to a kind of to sell the square tube diameter of axle pair directly to households
To locking device.
Background technology
Known, pin shaft joint is various heavy mechanical equipments, the moving parts such as particularly large-scale tower crane, Transport Machinery
A kind of conventional connecting mode.The main stressed member of traditional pin shaft joint is bearing pin body, and the main Impact direction of bearing pin body is footpath
To shearing force and surface radial compression power；So bearing pin is typically by axial force, therefore easily moves axially, in order to anti-
Shotpin axis body moves axially, generally using the bearing pin body with block machine；In order to prevent bearing pin install backward block machine direction play, one
As in the insertion end of bearing pin, radial direction through hole or neck are set, after bearing pin installation, after being inserted in circular washer at the end, inserted using split pin
Enter locking in radial direction through hole or locked with V shape opening jump ring insertion neck.
And the direct selling axle for specific type, its use environment do not allow to set block machine, it is desirable to sell end face and the work of axle directly to households
Make face flush, as shown in fig. 7, the lower boom of derrick runway girder sells the connection of axle directly to households, because dolly side wheel is run, side pin
Axle outer face can not exceed the lower boom lateral surface of arm support；In the prior art, flat using bearing pin one end facing cut, set square is welded in arm
On the inside of frame lower boom, bearing pin axial motion is prevented with split pin after bearing pin installation；Its shortcoming is：Bearing pin produces side force during installation
Set square is oppressed, after installation often, causes triangle plate welding seams to damage, further results in set square disengaging, it is impossible to prevent bearing pin
Set square rounding is caused bearing pin vibration by axial motion, bearing pin there may be radial rolling；As shown in figure 8, the arm support of tower crane is led
Draw the direct selling axis connection of pulley, it is desirable to which when indexing pulley normal activity, direct selling axle axial direction, radial direction are motionless；In the prior art, use
Ground shouldered pin, other end groove milling, is fixed after installation with baffle plate, and baffle plate is fixed by bolts on otic placode, and baffle plate prevents radially, the shaft shoulder
And baffle plate prevents axial motion；Its shortcoming is：When otic placode does not open gear not pair, baffle plate can not be installed, and shake under working condition, bolt meeting
Loosen, cause baffle plate to depart from, for a long time without using bolt, which easily gets rusty, to be turned, and cannot change pulley.
