Problems solved by technology

[0003] In the prior art, tower crane operators belong to high-altitude high-risk occupations, and fall accidents are very likely to occur when the operator enters and exits the tower crane, and when the tower crane loses control due to load, the operator has no way to escape at all, even in the insurance field. The tower crane operators are classified as six types of personnel, and the right to purchase insurance is not granted, which shows that the tower crane operators are at great risk

Embodiment

[0022] Such as figure 1 As shown, the induction control system for the tower crane of the present invention includes the following steps: S1: place the user's arm between multiple infrared sensors and turn on the infrared sensor; S2: when the infrared sensor is turned on, the current detected by the infrared sensor The infrared signal is regarded as the zero point; S3: When the infrared signal detected by the infrared sensor changes compared with the zero point, the tower crane is controlled according to the change. In the step S3, the following method is adopted to control the tower crane according to the change: when the infrared signal detected by the sensor at the upper part becomes stronger, and the infrared signal detected at the lower part becomes stronger, the hook of the tower crane is controlled to lift The arm moves near the point; when the infrared signal detected by the upper sensor becomes weak, and the infrared signal detected at the lower part becomes weak, the ...

Abstract

The invention discloses an inductive control system for a tower crane. A method comprises the steps that S1, a user arm is placed among a plurality of infrared sensors, and the infrared sensors are started; S2, when the infrared sensors are started, infrared signals detected by the infrared sensors serve as the zero point; and S3, when the infrared signals detected by the infrared sensors change compared with the zero point, the tower crane is controlled according to the change. According to the inductive control system for the tower crane, through the steps, control over the tower crane is achieved, thus an operator does not enter and get out of the tower crane, falling accidents do not appear, even if the tower crane loses control, safety of the operator can also be ensured, meanwhile, a new tower crane control bin does not need to be built, and cost is low.

Description

Technical field [0001] The invention relates to the field of tower crane control, in particular to an induction control system for the tower crane. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites, also known as "tower cranes", which are extended section by section (height) (referred to as "standard section") to lift steel bars and wood panels used in construction. , Concrete, steel pipe and other construction materials. Tower crane is an essential equipment on the construction site. The function of the tower crane tip is to withstand the upper load from the boom pull rope and the balance boom pull rope, and directly transmit it to the tower body structure through the slewing tower, turntable, bearing and other structural components. The top of the self-elevating tower has truncated cone column type, forward or backward tilting truncated cone column type, herringbone type and diagonal brace type. All upper slewing to...
