Abstract
The invention relates to an anti-creep device, in particular to a windproof anti-skid device for preventing an orbit-type crane from blowing away during outside work. The anti-creep device comprises an electric hydraulic thruster, skates, a pressure wheel and a lifting device. The pressure wheel is fixed under the crane; the skates are located below the pressure wheel; a gap is arranged between the skates and the pressure wheel; the skates are suspended on the lifting device on the upper part; the lifting device is connected with the electric hydraulic thruster which is connected with a motor of the crane; and the upper surfaces of the skates are concave. The invention has the advantages that the device is connected with a PLC (Programmable Logic Controller) electrical appliance control module to automatically identify the parking and operating states of the device; the automatic anti-creep device can automatically operate under the circumferences of inoperation or outage or sharp-edged gust of the crane so as to prevent the crane from sliding; the device has the time-delay function so that the device starts to operate when a cart operating mechanism is in brake parking, thereby preventing sudden brake from causing large inertial force.
Description
Technical field
The present invention relates to a kind of anti-creep device, is that a kind of locomotive crane at outside work prevents the windproof friction skidding device that blown away by strong wind.
Background technology
All to install at the locomotive crane of outside work such as handling bridge, transfer crane, bucket-wheel stacker reclaimer, span winch etc. and to prevent the windproof friction skidding device that blown away by strong wind; Claim anti-creep device; It is under the effect of electro hydraulicthruster, to make the skate that drops on the orbital plane mention or put down, and plays the slip that stops road wheel or the effect of rolling.Anti-creep device is the windproof friction skidding device of crane safety; Under crane operating status; Can defend the invasion and attack of flaw and play windproof protective effect, simultaneously also can with combineds action such as anchoring device, windproof stay cord, play the effect of the windproof automatic guarantee of safety under the hoisting crane off working state.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of anti-creep device is provided,, can work automatically, prevent that hoisting crane from sliding by PLC control.
According to technical scheme provided by the invention, a kind of anti-creep device comprises electro hydraulicthruster, skate, pressure wheel and lifting device; Pressure wheel is fixed under the hoisting crane, and skate is positioned at the pressure wheel below, and skate hangs on the lifting device of top through flexible element, and said lifting device is connected with electro hydraulicthruster; Said electro hydraulicthruster links to each other with the motor of hoisting crane.
Said skate upper surface is a spill.Be provided with the gap between skate and the pressure wheel.
Advantage of the present invention is: this device is connected with the PLC electrical control module, reaches the state that whole automatic identification equipments stop and turn round; Automatically anti-creep device can be worked when hoisting crane quits work or outage and under the situation of sharp-edged gust automatically, prevents that hoisting crane from sliding; Delay function is arranged, guarantee traveling mechanism of the larger traveller behind stopping-down, this device just works, in order to avoid braking suddenly causes excessive force of inertia.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in the figure: as to the present invention includes electro hydraulicthruster 1, skate 2, pressure wheel 3 and lifting device 4; Pressure wheel 3 is fixed under the hoisting crane, and skate 2 is positioned at pressure wheel 3 belows, is provided with the gap between skate 2 and the pressure wheel 3; Skate 2 hangs on the lifting device 4 of top through flexible element, and said lifting device 4 is connected with electro hydraulicthruster 1; Said electro hydraulicthruster 1 links to each other with the motor of hoisting crane.
Said lifting device comprises driven pulley 5; Connect steel rope 6; Elasticity coupling link 7 is formed, and connects steel rope 6 and through driven pulleies 5 electro hydraulicthruster 1 is combined with elasticity coupling link 7, is connected execution via elasticity coupling link 7 and skate 2 through pin again.
