Abstract
A limit system for a follow-up rail crane is characterized in that clamping arms are symmetrically hinged to the left side and the right side of a crane body at the upper end of an I-steel guide rail, the upper ends of the clamping arms are hinged to a cylinder body of a brake hydraulic cylinder and a piston cylinder respectively, an oil inlet and an oil return opening of the brake hydraulic cylinder are connected with an oil inlet and an oil return opening of an electromagnetic reversing valve respectively, a hoisting pre-control button and a control relay are serially connected into a circuit, a normally open contact of the control relay is parallelly connected with the hoisting pre-control button, one end of a hoisting start button is connected onto a joint of the hoisting pre-control button with the control relay, and the other end of the hoisting start button is connected with a hoisting control circuit.
Description
Technical field
The present invention relates to a kind of hoisting crane caging system, particularly a kind of trailing type track crane caging system belongs to the hoisting crane technical field.
Background technology
The locomotive crane of outdoor work, particularly harbour, are often blown away, blow down by strong wind easily, even blow to Jiang Haizhong, thereby cause enormous economic loss when unmanned operation is not taked measures necessary again with locomotive crane.Similar reason occurring is: unattended, when hoisting crane stops at a certain position, when sweeping strong wind; Especially wind-force is bigger, and more heavy-duty machine receives a certain side force, because of force of rolling friction between hoisting crane wheel and guide rail less; When wind-force acquires a certain degree, rise and pay attention to along the guide rail walking, and in case walking; Then produce acceleration/accel, walk faster and faster acting on of wind-force.And when going to tail track, because huge inertia, thereby hoisting crane is toppled over.In order to prevent the generation of this type of accident.Many users adopt the most original method, and after the end of job was shut down, artificial added a module between wheel and guide rail, and this method had both bothered also unreliable, can not reach the purpose of safety guard-safeguard.Also have some users to adopt mechanical brake device now, this device leans on spring force to clamp in orbit.Raised by hydraulic efficiency gear during the heavy-duty machine walking more, it prevents that wind-force from having provoked the sight machine and having moved the friction that light is produced by the spring gripping power entirely, so its braking force can not be very big again; The opposing party is in order to push spring force open, very big hydraulic thrust, so complex structure; Energy consumption is big, and it is also unreliable to brake.Be out of order easily.In addition, the position fixing system of existing hoisting crane generally is after hoisting crane quits work, and just plays the positioning action to hoisting crane, and in fact, hoisting crane owing to there is load, receiving under external force or the unexpected situation, more is easy to generate the danger of toppling in work.
Summary of the invention:
The objective of the invention is to: a kind of trailing type track crane caging system is provided, overcomes the existing above-mentioned defective of existing track crane caging system.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of trailing type track crane caging system; It is the left and right sides at the lifting fuselage of I-beam section guide rail upper end; Toggle clamp gripping arm symmetrically; The upper end of clamping limb is hinged with cylinder body, the piston cylinder of braking liquid cylinder pressure respectively; The oil inlet of braking liquid cylinder pressure links to each other respectively with return opening with the oil inlet of solenoid directional control valve respectively with return opening, and lifting is controlled button and control relay is connected in the circuit in advance, and it is parallelly connected that button is controlled in the open contact of control relay and lifting in advance; One of lifting start button is terminated at lifting control in advance on button and the node that control relay links to each other, an other end of lifting start button is connected with the lifting control circuit.
Principle of work of the present invention is: press lifting when controlling button in advance, at this moment, control relay is started working, and control relay is through the control solenoid directional control valve; Solenoid directional control valve is started working simultaneously, under solenoid directional control valve control, to the plunger shaft input hydraulic pressure oil of braking liquid cylinder pressure, so; The I-beam section guide rail is clamped in the clamping limb lower end that is installed in the left and right sides of lifting fuselage, the hoisting crane location, and at this moment, the lifting start button is connected simultaneously; After pressing the lifting start button, connect the hoisting operation circuit, at this moment, get into the hoisting operation program; Because lifting work and spacing chain each other is so when quitting work, said process is opposite.
Beneficial effect: the present invention is owing to lifting work and spacing chain each other, so the present invention has safe and reliable advantage.Effectively prevent at heavy-duty machine and working,, receive under external force or the unexpected situation, be easy to generate the danger of toppling owing to there is load.
