Description
Technical Field
The utility model relates to a building construction equipment field specifically is a tower machine jacket frame roller device convenient to installation.
Background
Among the prior art, the installation of the gyro wheel of tower machine set frame adopts welding formula cardboard round pin axle to install, the cardboard welding is in round pin axle one end, be equipped with the mounting hole on the cardboard, earlier arrange the gyro wheel in between two fixed plates of wheel carrier during the installation, utilize the instrument to pack the round pin axle into the mounting hole of two fixed plates and gyro wheel, then fix the cardboard on the fixed plate through the bolt again, because the cardboard is with round pin axle welded, there is certain welding deformation, and the cooperation of round pin axle and mounting hole is very strict again, the cooperation tolerance is very little, so often appear during the assembly that the round pin axle is difficult to pack into, the condition that the dress is not even, seriously influence installation quality.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model aims to provide a tower machine stock gyro wheel device convenient to installation improves welded type cardboard round pin axle into split type cardboard round pin axle, makes the installation of gyro wheel convenient and installation quality high fast.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a tower machine jacket frame gyro wheel device convenient to installation, includes wheel carrier, gyro wheel, round pin axle and cardboard, round pin axle one end is provided with the shaft shoulder, shaft shoulder one side is provided with the breach that is less than the semicircle, the round pin axle passes wheel carrier and gyro wheel, and the inboard wheel carrier surface of hugging closely of shaft shoulder, the cardboard is located the shaft shoulder breach department of round pin axle, cardboard one side and the laminating of the perpendicular tangent plane of shaft shoulder breach, the horizontal tangent plane and the wheel carrier surface of shaft shoulder breach are hugged closely to the cardboard bottom surface, just cardboard and wheel carrier fixed connection.
Preferably, the thickness of the shaft shoulder of the pin shaft is the same as that of the clamping plate.
Preferably, one end of the shaft shoulder of the pin shaft is provided with a grease nipple and a lubricating oil channel.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses improve welded type cardboard round pin axle into split type cardboard round pin axle, avoid influencing the assembly of round pin axle because of welding deformation, during the installation gyro wheel, because of the round pin axle does not carry out welding process, the event just has not just thermal deformation, in the mounting hole of wheel carrier and gyro wheel will be packed into to the round pin axle by the instrument very easily, again with cardboard card in round pin axle shoulder breach department, prevent that the round pin axle is rotatory and carry out axial positioning to the round pin axle to fix the cardboard on the wheel carrier with the bolt, whole installation is convenient fast and installation high quality.
