Abstract
A swing reducing device for a hoister hook belongs to a load hanging device of a crane. The swing reducing reel drum of the swing reducing device is manufactured with a section with un-equal diameters; the swing reducing reel drum is coupled with the main lifting reel drum; the hydraulic system of lifting tool is of no power form. The swing reducing device for a hoister hook has the functions of simplicity, legerity, quickness and reliable swing reducing ability, fitting for reducing swing for the suspended load of container cranes in railways, highway, port and any freight yard, and other classes of container cranes. The swing reducing device for a hoister hook can improve the loading and unloading efficiency.
Description
The utility model belongs to the load erecting by overhang of hoisting crane.
In the container hanging operation, for making suspender contraposition quick and precisely, improve handling efficiency, the specific purpose container hoisting crane is equipped with antirolling apparatus.The antirolling apparatus of external hoisting crane adopts complex hydraulic system forms such as torque motor more, container crane for the medium and small tonnage of China, have that mechanism's complexity, weight are big, problems such as maintenance difficulty and cost height, if particularly hydraulic part does not pass a test, then leakage of oil is serious, pollute the goods yard, the user very dislikes.
The purpose of this utility model is, for addressing the above problem, to subtract and shake reel and make non-equal diameter cross section, reach subtract shake the rope with main raising line synchronous, make hydraulic efficiency pressure system become unpowered type (not having devices such as motor, fuel tank and oil pump), system is greatly simplified, overcome the problem that complex hydraulic system exists, and saved electric energy.
Figure 1 shows that the lifting mechanism on the monkey and subtract swing mechanism; Fig. 2 shakes steel rope winding schematic diagram for subtracting; Fig. 3 is the sling hydraulic pressure schematic diagram.Among the figure: (1)-supporting; (2)---pulley; (3)-subtract and shake reel; (4)-electrical motor; (5)-drg; (6)-reductor; (7)-coupler; (8)-hoisting drum; (9)-supporting; (10)-gear; (11)-steel rope; (12)-oil cylinder; (13)-compression indicator; (14)-flow regulating valve; (15)-quick coupling; (16)-shutoff valve; (17)-energy storage.Subtract and shake reel (3) and drive by a pair of gear transmission by hoisting drum (8), subtract and shake steel rope (11) and be bonded on the piston rod of diagonal suspender oil cylinder through pulley (2), the epicoele of oil cylinder (12) is communicated with energy storage through flow regulating valve, subtract the size of shaking each diameter of section of reel and be according to the layout design of dolly top sheave (2) and suspender upper cylinder (12), in the suspender lifting process, subtract and shake reel and make to subtract and shake steel rope and main hoist rope is synchronous fully, subtract and shake steel rope in tension all the time, and the piston of oil cylinder is not moved, the loss of hydraulic efficiency pressure system noenergy.When suspender shakes because of reasons such as hoisting crane brakes in service, the distance of the corresponding dolly top sheave of each oil cylinder piston pole clearance (2) will change on four jiaos of the suspenders, to shake length of steel wire rope constant and subtract, certainly will cause the piston of each oil cylinder to move up and down like this, oil is extruded and produces loss of pressure when flowing through flow regulating valve, consumed and shaken mechanical energy, made and shake rapid decay, it is static that suspender recovers at short notice.Energy storage (17) can balance each oil circuit flow, and lax subtracting shaken steel rope and recovered tensioning state rapidly in providing pressure to make to shake.Energy storage can also be to the hydraulic efficiency pressure system repairing.Regulate the flow regulating valve openings of sizes and can control stabilizing efficiency.
Subtract and shake the reel vertical section grooving line of centres and can make as shown in Figure 4 cydariform, also can replace with as shown in Figure 5 half cydariform and taper shown in Figure 6.
It is light and handy that this crane hanger subtracts the swing mechanism structure, and reliable in action is easy to manufacture, owing to do not have hydraulic efficiency gear such as electrical motor, oil pump, fuel tank on the suspender, thus in light weight, and save electric energy.This mechanism is applicable to that container handling crane and other all kinds hoisting crane hang subtracting of carrying and shake.
Claims (2)
1, a kind of crane hanger subtracts swing mechanism, have and subtract winding mechanism and the sling hydraulic pressure system of shaking, it is characterized in that subtracting and shake the interlock of reel [3] and main hoisting drum [8], subtract and shake steel rope [11] and be connected through the piston rod of pulley [2] with suspender oil cylinder [12], the epicoele of oil cylinder [12] is communicated with energy storage [17] through flow regulating valve [11].
2, subtract swing mechanism by the described crane hanger of claim 1, it is characterized in that subtracting and shake reel and make non-equal diameter cross section.
