Abstract
The traveling anti-collision safe control system of snub-type crane comprises a distance sensing device, a brake control device, and a brake actuating device. The distance sensing device can sense a distance signal and convert the distance signal into an electric signal and then transmits the electric signal to the brake control device, the brake control device outputs a discontinuous snub signal to the brake actuating device. Compared with the prior art, the utility model can prevent a crane from impacting a bumper with a strong inertia force and reduce the inertia force by gradually reducing traveling speed of the crane. However, reducing the traveling speed of the crane can also reduce the work efficiency, so an encoder and the like can be installed to ensure the traveling speed is reduced by about 50% when the crane enters a distance about 5m from an track end, which can ensure the inertia momentum when the crane impacting the bumper can be reduced even when the limit switch of the crane fails.
Description
Technical field
The utility model system belongs to the hoisting crane technical field, specifically is a kind of point braking type hoisting crane that is used for transfer crane etc. crashproof safety control system of walking.
Background technology
The hoisting crane that transfer crane etc. are walked in orbit when walking to tail track, sends signal cut movable motor power supply by limit switch, its objective is to allow hoisting crane not plunge off the tracks.But the impact that is subjected to during hoisting crane work is very serious, add that working environment is generally all relatively poor, the damage rate of limit switch is very high, and this can cause the effect of hoisting crane force of inertia and impact the car bumper of tail track, can cause the danger that hoisting crane damages and hoisting crane plunges off the tracks in the course of time.
Summary of the invention
In order to prevent that hoisting crane from impacting the car bumper of tail track, reduce hoisting crane and damage probability, prevent that hoisting crane from plunging off the tracks, the utility model system proposes a kind of applicable to the hoisting crane of common small-sized no variable frequency control, also applicable to goliath, the hoisting crane walking anticollision safety system that impacts of minimizing equipment significantly, concrete technical scheme is as follows:
A kind of point braking type hoisting crane crashproof safety control system of walking comprises distance sensing device, braking control device and brake executive device; Described distance sensing device distance of reaction signal, and pass to braking control device after range signal converted to electric signal, the braking control device output point of discontinuity signal of stopping is given the brake executive device.Described braking control device is PLC; Described brake executive device is a drg.
As improving 1, described distance sensing device is a rang sensor, and rang sensor has two groups.Two groups of rang sensors are located at the head and the tail two ends of hoisting crane, the distance when being used to induce the heavy-duty machine forward-reverse respectively.
Can also further select speed sensor for use; Described speed sensor induces the heavy-duty machine speed of travel, and speed signal is converted to electric signal passes to braking control device.
As improving 2, described distance sensing device is an inductor, and inductor output electric signal is given braking control device.Inductor is embedded in predetermined normal danger, induces the heavy-duty machine walking position.
Equally, can also further select speed sensor for use; Described speed sensor induces the heavy-duty machine speed of travel, and speed signal is converted to electric signal passes to braking control device.
As improving 3, described distance sensing device is a coder.Coder can be the cireular frequency that induces the heavy-duty machine road wheel, also can be the cireular frequency (this mode, actual is the cireular frequency of indirect induction line travelling wheel) of the drive motor of induction line travelling wheel.Because native system is to be used for the hoisting crane of walking in orbit such as transfer crane, the walking path of hoisting crane is fixed, so, can induce the cireular frequency of heavy-duty machine road wheel with coder, calculate by programming, obtain the linear velocity of hoisting crane road wheel and travel distance etc.
In the technique scheme, in brake process, the speed of hoisting crane be can gather simultaneously, quantity and density that point is stopped signal output determined.
The action principle of the utility model system is, coder/inductor/rang sensor (sending signal)-PLC (send point of discontinuity stop signal)-drg (point is stopped and realized the deceleration purpose)-reduce and impact.
Compared with prior art, the utility model system can prevent that hoisting crane from impacting car bumper with huge force of inertia effect, reduces force of inertia with the method that reduces the hoisting crane speed of travel gradually.But reduce the hoisting crane speed of travel and also can reduce work efficiency, so can be when coder etc. being installed allowing in the 5m left and right sides scope of the hoisting crane injection end, the speed of travel is reduced about 50%, even the inertia kinetic energy like this during the impact of the limit switch of hoisting crane inefficacy also can minimizing hoisting crane.
