Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the crane chassis of the invention is composed of a chassis 1, the upper side of the chassis 1 is connected with a mounting block 2, as shown in fig. 2, the mounting block 2 includes a mounting hole 4 and an underframe cavity 5, the periphery of the mounting hole 4 is connected with the underframe cavity 5, as shown in fig. 3, a plurality of fixing plates 6 are installed at both sides of the chassis cavity 5, as shown in fig. 4, the fixing plates 6 are provided with screw holes 7, the lower side of the chassis 1 is connected with a connecting plate 8 through a hydraulic press 3, the connecting plate 8 is connected with wheels 10 through an axle 9, the lower outer side of the chassis 1 is connected with a regulator 12 through a connecting block 11, as shown in fig. 5, the regulator 12 includes a plurality of hydraulic pipes 13, the hydraulic pipes 13 are connected to two first connecting rods 15 by a first rotating shaft 14, the left connecting rod 15 is connected with a roller 17 through a second rotating shaft 16, and the right connecting rod 15 is connected with a supporting pad 18. The crane can be connected with the underframe cavity 5 through the mounting hole 4 and fixed through the screw hole 7 on the fixing plate 6, so that the stability of the crane can be enhanced; hydraulic pressure pipe 13 can promote or descend first pivot 14 as required, when needs remove, rotates gyro wheel 17 unanimously with the direction of advance through first pivot 14, when needs stabilize the hoist, rotates supporting pad 18 to adaptation position through first pivot 14 and plays the supporting role, uses convenient high efficiency, and stability is strong.
