Abstract
The invention relates to a building crane. The building crane comprises a vertical support frame, a horizontal support frame, a moving body, a lifting rope, a lifting hook, a semi-ring metal ring, a circuit, a rectifier bridge system, a triode amplification system, an electromagnetic type relay system, an electric system, an operation room, a camera and a pressure sensor. Through the building crane, the electric shock of operators when the operators work near high-voltage wires can be effectively avoided; meanwhile, working information of the lifting rope and the lifting hook of the building crane can be fed to the operators clearly. The building crane is simple to operate and easy to popularize.
Description
Technical field
What the present invention relates to is a kind of crane, particularly a kind of construction-site crane.
Background technology
Construction-site crane is a kind of weight-lifting equipment the most frequently used on building ground, with a section spreading (height), as the form of a steel tower, is used for hanging construction and uses to obtain the raw-material equipment of construction such as stupefied, the scaffold tubes of reinforcing bar, wood.A kind of requisite equipment of building operation.For the classification of construction-site crane, can be divided into pitching amplitude variation type and carriage amplitude varying formula by luffing mode, can be divided into by operating mode can jack up and can not jack up, movable arm type can be divided into and bottom is rotary by the mode of turning, can be divided into rail mounted and jellyfish posture by fixed form, cab over type and tip formula can be divided into by pinnacle of a pagoda structure, machine automatization and manual control can be divided into by mode of operation.By having or not traveling gear can be divided into portable tower and fixed type.Can be divided into and can be divided into lower revolution mode and upper rotary mode according to structure revolution mode.
Construction-site crane is generally applied in building operation place.In the time that building operation place exists high tension cord, the use of construction-site crane is just restricted, and when construction-site crane is worked near high tension cord, is easy to occur dangerous.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the present invention is to provide a kind of construction-site crane, be easy to make operating personal to occur the problem of Danger Electric shock risk for solving when prior art construction-site crane is worked near high tension cord.
In order to achieve the above object, a kind of construction-site crane of the present invention, is made up of vertical bracing frame, horizontal shore, moving body, lifting rope, suspension hook, semi-ring wire loop, circuit, rectifier bridge system, aerotron amplification system, electromagnetic type relay system, power driven system, operator's compartment, camera, pressure sensor.
Described vertical bracing frame is connected with horizontal shore, and horizontal shore is connected with operator's compartment, and lifting rope is connected with moving body, and moving body is connected with horizontal shore, and suspension hook is connected with lifting rope.
Described semi-ring wire loop is connected on horizontal shore, semi-ring wire loop is connected with rectifier bridge system by circuit, rectifier bridge system is connected with aerotron amplification system by circuit, aerotron amplification system is connected with electromagnetic type relay system by circuit, and electromagnetic type relay system is connected with power driven system by circuit.
Camera is connected with moving body, and pressure sensor is connected with moving body.
The two ends of semi-ring wire loop are connected with IN1 port and the IN2 port of rectifier bridge system respectively, the GND port ground connection of rectifier bridge system, the OUT1 port of rectifier bridge system is connected with the base stage B port of aerotron amplification system, connect+12V of the collecting electrode C power supply of aerotron amplification system, the emitter E of aerotron amplification system is connected with the IN2 port of electromagnetic type relay system, the IN1 port of electromagnetic type relay system connects the needed high tension supply of motor operation, and the IN3 port of electromagnetic type relay system connects electrical motor positive pole.
The present invention can effectively prevent from when operating personal from working near high tension cord getting an electric shock.When horizontal shore of the present invention is during near high tension cord; the interior magnetic flow of semi-ring wire loop changes thereby produces inducing current; this current signal is first passed to rectifier bridge system by circuit; pass through again aerotron amplification system; finally pass to electromagnetic type relay system; now move electromagnetic type relay internal system contact, and power driven system is quit work, and has finally protected the safety of operating personal.The effect of pressure sensor is to detect the gravity that is raised object, prevents overload situations.The effect of camera is the job information to operating personal feedback lifting rope, suspension hook.
Advantage of the present invention is: can effectively prevent that operating personal from working near high tension cord time, get an electric shock, can effectively prevent overload situations, the job information of effectively life-saving, and lifting rope, suspension hook can be fed back to operator by clear.
