Embodiment 1
[0031] As a preferred embodiment of the present invention, the present invention discloses a new type of trolley device for crane traveling mechanism, including a trolley frame 5, traveling wheels 6 mounted on the trolley frame 5, a hinge seat 4, and an upper bracket 1. And the slewing support 2, the hinge base 4 is fixed on the trolley frame 5, and the slewing support 2 is connected between the hinge base 4 and the upper bracket 1. When the crane runs on the arc-shaped track, due to the track layout and crane installation When the wheel rim collides with the side of the curved track due to various reasons such as operation, the trolley rotates freely through the slewing bearing 2 under the action of horizontal horizontal force, thus avoiding the occurrence of jamming and effectively ensuring The traveling mechanism of the cart runs smoothly on the curved track. At the same time, the trolley can rotate freely in the horizontal plane, can withstand large axial forces, can withst...
Embodiment 2
[0033] As the best embodiment of the present invention, refer to the appendix of the specification figure 1 with 2 , The specific structure is: a three-row roller slewing support 2 is set between the hinge base 4 and the upper bracket 1 of the walking trolley, the slewing bearing 2 is placed horizontally, and the slewing bearing 2 is connected to the supporting hinge and the upper bracket 1. Bolted connection between. The walking wheel 6 of the gantry crane has a double rim, and the tread width of the wheel is 5-10 cm wider than that of a standard wheel to adapt to the curvature of the curved track. The trolley device has the following characteristics: the trolley can rotate freely in the horizontal plane, can withstand large axial forces, can withstand large tilting moments, and can withstand large horizontal radial forces, and has small dimensions; When traveling the trolley, place the centerline of the two wheel treads of the traveling trolley and the arc centerline of the t...
