Automatic driving system of tower crane and tower crane

Abstract

The invention discloses an automatic driving system of a tower crane and the tower crane. The automatic driving system of the tower crane comprises a tower crane electromechanical mechanism, an on-tower cab, a ground control station and a wireless communication module, the tower crane electromechanical mechanism comprises a traveling mechanism, a swing mechanism, a luffing mechanism and a hoisting mechanism, the on-tower cab is provided with an unmanned automatic control system, the on-tower cab comprises an on-tower controller, the on-tower controller is in signal connection with a series of sensors in the tower crane electromechanical mechanism and a motor of a working mechanism, the ground control station comprises a ground controller, and the on-tower controller is in remote signal connection with the ground controller through the wireless communication module. According to the automatic driving system of the tower crane and the tower crane, the use of GPS or GNSS positioning system equipment is omitted, all tower crane electromechanical mechanisms are self-driven in a fixed route according to a path and a control command specified by the system by virtue of all the sensors which are distributed in the prior art, and automatic driving in the fixed route is realized, so that a tower crane lifting hook reciprocates between a material point and a construction point, and the working efficiency and reliability of the tower crane are improved.

Description

technical field [0001] The invention relates to the technical field of building construction safety, in particular to a tower crane automatic driving system and a tower crane to which the tower crane automatic driving system is applied. Background technique [0002] The construction industry has always been a pillar industry of the national economy, providing strong support for the sustainable and healthy development of my country's economy. However, the production mode of the construction industry is still relatively extensive, and the traditional construction techniques and construction methods can no longer meet the requirements of sustainable social development. quality development. [0003] Tower cranes are necessary building material transfer equipment on construction sites. They are connected to materials with hooks, and transport materials to designated locations through actuators such as booms, trolleys, and hooks. However, safety accidents due to improper operati...

AI Technical Summary

Problems solved by technology

[0004] 1. The driver drives at high altitude for a long time, which is easy to cause visual fatigue, harsh working environment, high psychological pressure, and high risk of misoperation and illegal operation;

[0005] 2. When encountering a problem, the driver needs to independently judge how to deal with it, and it is difficult to guarantee the optimal operation;

[0006] 3. It must involve repeated transfer of materials along a fixed route, which is prone to fatigue, high probability of operational errors, and low efficiency of manual operation;

[0007] 4. The tower crane system often only prompts risks according to pre-set rules, and the driver still needs to decide how to operate

At the same time, because the driver often operates the luffing mechanism, the hoisting mechanism and the slewing mechanism independently, the operating efficiency of the tower crane is low;

[0008] 5. The drivers of tower cranes are scattered in various construction sites, which is not convenient for centralized organization and management

[0009] In addition, the currently disclosed tower crane automatic driving system often requires GPS or GNSS positioning system equipment, which not only increases the cost and system complexity, but also reduces the feasibility and reliability of the automatic driving system due to problems such as signal occlusion and positioning system failure.
