However, in the prior art, the trolley frame of this type of crane is usually rigidly connected, does not have the effect of adaptive adjustment and buffering, and can easily cause breakage between the main beam and the crane beam.

[0003] To this end, the utility model provides a crane self-adaptive lifting frame to solve the above technical problems. Utility Model Content

[0009] A guide wheel device, which is used to guide and limit the crane beam. A total of four guide wheel devices are provided and are symmetrically arranged in pairs on two webs. The guide wheel devices are fixedly arranged on the outer side of each pulley position;

[0010] An adaptive component is installed between two webs through a connecting shaft. The adaptive component is used for adaptively adjusting the position of the crane beam and the main beam after the trolley frame is installed.

[0011] Furthermore, the adaptive component includes:

[0012] A joint bearing frame, both ends of which pass through the connecting shaft and are arranged between the two webs;

[0013] A universal coupling, the universal coupling is installed through the joint bearing frame, and the joint of the universal coupling is arranged on the joint bearing frame;

[0014] A clamping plate is installed at both ends of the universal joint, and the universal joint is fixed by the clamping plate to install the trolley frame as a whole on the main beam.

[0015] Furthermore, a reducer is installed on the frame body, and the reducer is used to adjust the rotation speed of the pulley.

[0016] Furthermore, a buffer is provided on the joint bearing frame extending in the movement direction.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By setting up an adaptive component, the universal joint in the adaptive component can play a buffering effect when the main beam and the crane beam move relative to each other. The setting of the pulley, guide wheel and reducer enables the trolley frame to drive the main beam to move on the crane beam, changing the original crane installation method, making the installation more compact and saving space.
