Remote-controlled tower crane

Abstract

A remotely controlled tower crane is composed of main body, remote control unit, and executing unit. Said remote control unit consists of an emitter comprising encoder, modulation amplifier, HF oscillator and power supply, and a receiver comprising HF amplifier, ultraregeneration detector, amplifying shaper, decoder, driver, indicating alarm circuit and power supply.

Description

technical field [0001] The invention relates to a tower crane, in particular to a remote-controlled tower crane. Background technique [0002] At present, the operation of the tower crane used in the construction field is controlled by the operator in the operating room located on the top of the tower crane. Due to the relatively high tower crane and its special structure, the operator is located far away from the working surface, and must have the cooperation of the ground staff to complete a series of tasks. The ground staff often use gestures and other methods to communicate and command, so that It is difficult to ensure that the operation work is accurate and error-prone. And because the workplace is outdoors, it is easily affected by the environment, especially in rainy days, hoisting work cannot be carried out. At the same time, operators have to climb up and down many times a day, so there are also high requirements for operators. This kind of tower crane not only h...

Problems solved by technology

Due to the relatively high tower crane and its special structure, the operator is located far away from the working surface, and must have the cooperation of the ground staff to complete a series of tasks. The ground staff often use gestures and other methods to communicate and command, so that It is difficult to ensure that the operation work is accurate and error-prone

And because the workplace is outdoors, it is easily affected by the environment, especially in rainy days, hoisting work cannot be carried out. At the same time, operators have to climb up and down many times a day, so there are also high requirements for operators. This kind of tower crane not only has a relatively high risk, but also it is difficult to maintain accurate coordination between the ground construction commander and the tower crane operator, and it is very inconvenient to use. In order to overcome the problem of inconvenient operation of the tower crane, someone has also used it before. The method of wireless remote control was used to operate the hoisting construction test of the tower crane on the ground, but due to technical problems, the real wireless remote control operation of the tower crane could not be realized.
