Remote control safety tower crane based on point position coordinate and hoisting method of remote control safety tower crane

Abstract

The invention discloses a remote control safety tower crane based on a point position coordinate and a hoisting method of the remote control safety tower crane. The remote control safety tower crane comprises an aerial photography device, a wireless transmitter and receiver, a remote controller, a central controller, an alarm device, a display device and a tower crane collision prevention pre-warning system, wherein the aerial photography device is located at the tip of a tower crane body, and is sequentially connected with the remote controller and the central controller in a cab of the tower crane body through the wireless transmitter and receiver; the central controller is also connected with the alarm device, a motor of the tower crane body and the tower crane collision prevention pre-warning system; the tower crane collision prevention pre-warning system comprises a safety distance measurement system which is connected with the central controller; and the safety distance measurement system is sequentially connected with an ultrasonic probe, a temperature sensor and a humidity sensor through wireless signals. The hoisting method is simple to operate; tower crane operating personnel has the scientific basis when operating the tower crane due to an intelligent operation; and the relatively normative and scientific operation can be carried out.

Description

technical field [0001] The invention relates to a tower crane used in construction, in particular to a remote control safety tower crane based on point coordinates. Background technique [0002] Tower crane is the most commonly used lifting equipment on the construction site. an essential device. [0003] However, with the use of tower cranes, some safety problems have also been exposed. One of the main problems is the driver's line of sight during the operation. The scene on the construction site is more complicated, and there are many obstacles, and the driver's line of sight is often blocked. At this time, if the operation is improper, it is easy to cause a safety accident. At present, on the construction site, the ground staff mainly tells the driver the specific situation below through the walkie-talkie or the signal flag-bearer. This is not only time-consuming and laborious, but also a huge safety hazard if the language is wrong. [0004] Due to the characteristics ...

Problems solved by technology

[0005] The purpose of the present invention is to: provide a remote control safety tower crane based on point coordinates, which solves the problem of the driver's blind spot in operation, and take aerial photography of the construction site where the tower crane is located through the aerial photography device, and make a grid coordinate map, using angle-coordinate The expression method of the construction site is realized to accurately locate the position on the construction site, and finally the motor operation of the tower crane is controlled by the remote control, so as to avoid the potential safety hazards caused by the blind area of ​​the operator's perspective and the instruction operation of the ground staff; the anti-collision warning system of the tower crane is adopted to Ultrasonic distance measurement is performed on the buildings around the tower crane, and the alarm prompts to prevent the tower crane from colliding with the surrounding buildings; in addition, a hoisting method based on point coordinates for remote control of the tower crane is provided. This hoisting method enables the tower crane to operate intelligently The personnel have a scientific basis when operating the tower crane, and can operate in a more standardized and scientific manner
