Embodiment Construction

[0012] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0013] Such as figure 1 As shown, an electric hoist single and double girder crane trolley includes a vehicle frame 1, the front of the vehicle frame 1 is connected with two No. 1 wheels 3 through the first rotating shaft 2, and the rear of the vehicle frame 1 is connected with the second rotating shaft 4. Two No. 2 wheels 5, the second rotating shaft 4 is linked with the motor 6, the second rotating shaft 4 is connected with a gear 7, the gear 7 meshes with the gear on the output shaft of the motor 6, the motor 6 is installed on the vehicle frame 1 through a fixed plate, and the motor 6 drives the two No. 2 wheels 5 to run, which ensures the synchronization of the trolley in the running process, avoids deviation phenomenon, reduces manufacturing costs, and improves work efficiency.

[0014] Finally, it should be noted that the above spe...

Abstract

The invention relates to the technical field of cranes and discloses a single and double girder crane trolley of an electric hoist. The single and double girder crane trolley comprises a trolley frame, wherein the front part of the vehicle frame is connected with two driven wheels by virtue of a driven rotary shaft, the back part of the vehicle frame is connected with two driving wheels by virtue of a driving rotary shaft, and the driving rotary shaft is linked with a motor. As one motor drives the two driving wheels so as to drive the single and double girder crane trolley to run, the synchronism without off tracking of the trolley in the running process is ensured, the manufacturing cost is also lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an electric hoist single- and double-girder crane trolley. Background technique [0002] With the vigorous development of my country's iron and steel industry, crane technology is also constantly improving. Cranes will be gradually put into use in more industries in the future to reduce the work intensity of personnel and increase work efficiency, which will inevitably affect the stability of cranes. Sexuality puts forward higher demands. Among the lifting equipment, the electric hoist bridge crane is widely used due to its compact size, light weight, and small wheel pressure. The wheel sets of the current trolleys for cranes are driven by two motors respectively. This structure easily leads to asynchronous operation of the wheels, which is not easy to control, and the cost is also high. Contents of the invention [0003] The technical problem to be solved by the present invent...
