Autobalance tower type crane

Abstract

The invention discloses an autobalance tower type crane, and belongs to the technical field of cranes. The problems that due to the fact that force borne by a balancing arm and a cargo boom are different, the unbalance situation of an existing tower type crane is serious, and both time and labor are consumable when a stock is lifted up can be solved. The autobalance tower type crane comprises a stock located at the top end of a tower body, a balancing arm and a cargo boom are located at the top end of the stock, and located on the two sides of the stock correspondingly, a jib lubbing mechanismis arranged on each of the balancing arm and the cargo boom, a hook is connected to the cargo boom through a steel wire rope, a balance weight object is located on the balancing arm, the cargo boom becomes slender from the end, close to the stock, to the tail part, the jib lubbing mechanism on the balancing arm comprises a power source, the power source is connected with a motor through a horizontal switch, the output end of the motor is connected with the input end of a gear reducer, the output end of the gear reducer is connected with a coiling block, the coiling block is connected with thebalance weight object through the steel wire rope, a travel switch is arranged at the end, away from the stock, of the balancing arm, and the travel switch is connected with the jib lubbing mechanisms on the balancing arms and the cargo booms in series. The autobalance tower type crane can save both time and labor, and is high in safety performance.

Description

technical field [0001] The invention belongs to the technical field of cranes, in particular to an automatic balancing tower crane. Background technique [0002] Tower cranes are one of the widely used mechanical equipment in the construction industry. Because tower cranes are generally used in high-rise buildings for high-altitude operations, the balance of tower cranes is very important for safe production. [0003] Existing tower cranes include a tower body and a cover frame positioned at its top. The cover frame is provided with a rotatable balance arm and a lifting arm. The balance arm is fixed with a balance weight. The opposite sides of the luffing trolley are connected to the luffing mechanism through steel wire ropes, and a hydraulic jacking mechanism is provided on the sleeve frame. When working, because the quality of the balance weight remains unchanged, the luffing trolley is on the boom. Sliding back and forth, especially when the luffing trolley of the tower ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems of the existing tower cranes that due to the different forces on the balance arm and the lifting arm, the unbalance is serious and the time-consuming and labor-intensive raising of the sleeve frame is provided, and an automatic balancing tower crane is provided.
