Abstract
The utility model relates to a crane windproof device with an orbit. A pusher is in a powerdown state when an iron wedge is raised by the windproof device and the crane moves and works; a machine frame of the windproof device is provided with the pusher and a drive mechanism which comprises a drive shaft, a brake arm, a lever, and a main lever; the drive shaft is arranged on the machine frame; one end of the lever is fixed on the drive shaft, and the other end is connected with the push rod; one end of the main lever is fixed on the drive shaft, and the other end is connected with the brake arm; the other end of the brake arm is provided with the iron wedge; one end of the positioning rod is fixed on the machine frame, and the other end is provided with a signal switch which can be touched by the lever; a positioning device which is used for stopping the lever is arranged between the machine frame and the lever; the signal switch of the circuit in which the pusher exists is touched by the lever and is turned off when the iron wedge is kept in a raising state by the positioning device, which leads the pusher to turn off the power, thus, the electricity is saved as well as the service life of the pusher is prolonged.
Description
Technical field
The utility model relates to a kind of hoisting crane wind-proof device, especially is applicable to the rail hoisting crane, and traveling mechanism of the larger traveller such as handling bridge, span winch.
Background technology
Hoisting crane is in the loading and unloading operation process, and regular meeting runs into the indefinite high wind of wind-force, wind direction, the invasion and attack of fitful wind; Under the unware situation of operating personal, hoisting crane is moved by wind, and operating personal can't in time stop, and influences normal lifting operation, can cause disastrous effects such as sport car, overturning when serious.Existing hoisting crane wind-proof device can head it off, but existing hoisting crane wind-proof device takes, as number of patent application 00235671.6 " hoisting crane wind-proof device ", when the brake control lever of hoisting crane wind-proof device is mentioned iron wedge, hoisting crane walking work, pusher is in the energising mode of operation all the time, promptly takes the service life that electricity has reduced pusher again.
Summary of the invention
The purpose of this utility model is when the brake control lever of hoisting crane wind-proof device is mentioned iron wedge, hoisting crane walking work, to make pusher be in off-position.
For achieving the above object, the utility model adopts following technical scheme: this hoisting crane wind-proof device, comprise the frame that is fixed on the crane locomotive wheel carrier, an electro hydraulicthruster is set on the frame, the push rod of described pusher is connected with transmission device on being located at described frame, this transmission device comprises axle drive shaft, brake control lever, lever and main lever, described axle drive shaft is arranged on the frame, described lever one end is fixed on the axle drive shaft, the other end is connected with described push rod, one end of described main lever is fixed on the axle drive shaft, the other end is connected with described brake control lever, and the other end of described brake control lever is provided with the iron wedge, and an end of radius stay is fixed on the described frame, the other end is provided with and can be provided with the registration device that makes described lever stop between frame and lever by the signal switch of lever shake-up.
Described registration device is to be made of with the reverse link that is arranged on described lever and described push rod junction elongated end the electromagnet that is fixed on the described frame, and described reverse link has a hole that matches with electromagnet.
Hoisting crane is when the walking operation, and existing hoisting crane wind-proof device is removed the braking to hoisting crane, needs pusher work to keep the iron wedge to be raised; And employing the utility model can keep the iron wedge to be raised by registration device, and simultaneously the signal switch that is touched in the circuit of control pusher place by lever opens circuit, and makes the pusher outage, is power saving like this, has prolonged service life of pusher again.
