Double-driving-wheel anti-deviation ultra-low type end beam structure suspension crane

Abstract

The invention relates to a double-driving-wheel anti-deviation ultra-low type end beam structure suspension crane which comprises power mechanisms, an end beam mechanism, transmission mechanisms, guide mechanisms, a main beam and wheel sets. The power mechanisms, the transmission mechanisms, the guide mechanisms and the wheel sets are arranged at the front end and the rear end of the end beam mechanism, and the main beam is fixed to the bottom of the end beam mechanism. The power mechanisms are connected with the wheel sets, the wheel sets and the end beam mechanism are arranged in parallel, the installation height of the main beam can be increased, and therefore the hoisting height is increased. The transmission mechanisms are connected to the bottoms of the wheel sets, and therefore active synchronous transmission of wheels on two sides of each track can be realized, the situation that the left wheels and the right wheels are consistent in step in the operation process is guaranteed, and the phenomenon that wheels are not synchronous and slip in a traditional driving mode is eliminated. The Guide mechanisms are fixed to the front top end and the rear top end of the end beam mechanism, guide wheels can abut against the side faces of the tracks, and the wheels are prevented against the track gnawing phenomenon on the tracks.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an ultra-low type end beam structure suspension crane with double drive wheels and anti-running deviation. Background technique [0002] The full text of the suspension crane is a flexible light combined suspension crane, which is also a light and small lifting equipment. There are two types of suspension cranes: single-girder and double-girder. The main advantages include lifting capacity up to 2000 kg, easy installation, safety and so on. Due to its unique advantages, suspension cranes are widely used in parts assembly, manufacturing and processing, pallet loading, injection molding, storage loading and unloading, equipment maintenance and other industries. Suspension cranes include JKBK-D monorail suspension cranes, JKBK-LD single-girder suspension cranes, JKBK-LS double-girder suspension cranes, JKBK-LSS telescopic beam suspension cranes, JKBK-LM stackers, etc., with a wide range of a...

Problems solved by technology

[0004] 1. The wheel group structure of the cart is suspended under the end beam through the trolley wall plate and pin shaft, and the end beam is also suspended under the I-beam of the running track of the vehicle. Therefore, when the height of the factory building is fixed, the installation height of the main beam Due to the above reasons, there will be a relatively large reduction, so the lifting height will be reduced, which will affect the operating range and efficiency of lifting and transportation operations;

[0005] 2. The driving wheel and the passive wheel are rigidly connected, and the driving device drives the driving wheel on one side to roll on the I-steel track, and the rigid part drives the wheel on the other side to passively roll on the I-steel track, resulting in the I-steel track The asynchrony between the upper active wheel and the passive wheel may easily lead to errors or even slippage of the wheels on both sides, which will affect the service life, work efficiency and safety of the suspension crane;

[0006] 3. The wheels rotate and move on the I-steel track. The distance between the left and right wheels is fixed by the rigid connection at the bottom of the end beam. The wheels are not constrained by lateral force, and the left and right wheels are still easy to run on the I-steel track. This will not only affect the smooth operation of the end beam and the crane on the I-beam track, but also reduce the service life of the suspension crane
