Abstract
The utility model relates to the field of construction machinery, in particular to a rolling wheel assembly, a lifting cage where the rolling wheel assembly is used and a construction elevator. The rolling wheel assembly comprises a wheel shaft and a rolling wheel rotatably assembled on the wheel shaft through a bearing. The wheel shaft is an eccentric shaft, and a fastening nut is assembled at the position of one end of the wheel shaft for being matched with the lifting cage. Due to the fact that the wheel shaft of the rolling wheel assembly is the eccentric shaft and the fastening nut is assembled at the position of one end of the wheel shaft for being matched with the lifting cage, the wheel shaft can be rotatably inserted into a shaft mounting hole arranged on the corresponding lifting cage in use and then is fixed through the fastening nut. When the wheel shaft is used for a period of time and the rolling wheel is abraded, abrasion of the rolling wheel can be compensated only by loosening the fastening nut so as to appropriately rotate the wheel shaft, the rolling wheel assembly is convenient and fast to maintain, on one hand, a normal work cycle of the construction elevator is increased, on the other hand, waste of the rolling wheel is also avoided, and the problem that an existing construction elevator is high in cost due to rolling wheel abrasion is solved.

Have with position between clamp nut the bulge loop that coordinates with the bearing block at bearing on described wheel shaft, be provided with shaft seal between the outer peripheral face of this bulge loop and the inner peripheral surface of roller.
Be provided with the gear platform that clamps cage for coordinating with clamp nut on wheel shaft between clamp nut and bulge loop.
Cage of the present utility model is by the following technical solutions: cage, be equipped with roll wheel assembly on this cage, roll wheel assembly comprises wheel shaft and rotates the roller that is assemblied on wheel shaft by bearing, described wheel shaft is eccentric shaft, roll wheel assembly coordinates by axle mounting hole set on wheel shaft and cage and is assemblied on cage, and wheel shaft is rotating to be inserted in corresponding axle mounting hole and to fix by clamp nut.
Have with position between cage the bulge loop that coordinates with the bearing block at bearing on described wheel shaft, be provided with shaft seal between the outer peripheral face of this bulge loop and the inner peripheral surface of roller.
Be provided with the gear platform that clamps cage for coordinating with clamp nut on wheel shaft between described bulge loop and cage.
Building hoist of the present utility model is by the following technical solutions: building hoist, comprise pylon and be assemblied in cage on pylon, roll wheel assembly on cage coordinates with guide rail on pylon, roll wheel assembly comprises wheel shaft and rotates the roller that is assemblied on wheel shaft by bearing, described wheel shaft is eccentric shaft, roll wheel assembly coordinates by axle mounting hole set on wheel shaft and cage and is assemblied on cage, and wheel shaft is rotating to be inserted in corresponding axle mounting hole and to fix by clamp nut.
Have with position between cage the bulge loop that coordinates with the bearing block at bearing on described wheel shaft, be provided with shaft seal between the outer peripheral face of this bulge loop and the inner peripheral surface of roller.
Be provided with the gear platform that clamps cage for coordinating with clamp nut on wheel shaft between described bulge loop and cage.
because the wheel shaft of roll wheel assembly of the present utility model is eccentric shaft, and an end place that is used for coordinating with cage of wheel shaft is equipped with clamp nut, therefore, can be inserted in axle mounting hole set on corresponding cage wheel shaft is rotating in use, then get final product by described clamp nut is fixing, when using a period of time and rolling wheel wear, only need become flexible the wearing and tearing that the suitable rotating axle of clamp nut can compensate for roller, easy to maintenance quick, increased on the one hand the normal operation cycle of building hoist, improved its work efficiency, also avoided on the other hand the waste of roller, solved the high problem of cost that existing building hoist causes due to rolling wheel wear.
