Abstract
The utility model discloses a discharge mechanism capable of discharging muck in any position in a lifting height range. The discharge mechanism comprises a main hoisting mechanism, a variable frequency motor, a transmission shaft, a brake, a reductor, two windlasses and a muck hopper, wherein an encoder is arranged on the input shaft of the windlass; a lifting appliance and a rope, which are arranged below the input shaft, are connected to the input shaft; the upper end of the rope is connected to the lifting appliance; and the lower end of the rope is sleeved and hung on an eccentric lifting eye of the muck hopper. The variable frequency motor drives the windlasses at the same time; and muck overturning and discharging can be realized by utilizing the windlasses through the eccentric distance between two lifting points on the muck hopper for the lifting appliance and the rope and two lifting points on the muck hopper for the main hoisting mechanism. As the discharge mechanism can overturn and dump muck in the muck hopper in any position in the lifting height range, the working condition suitability is high; and as hooking and unhooking operation of a rigid hard hook is eliminated from the whole working process, the overturning and the dumping are more flexible, faster and safer, the work efficiency is improved, and the work intensity of a driver is reduced.
Description
Technical field
The utility model belongs to subway work and uses elevator machinery, relates to a kind of dregs shedding mechanism.
Background technology
Main gantry crane or the crawler crane of adopting of subway work dregs output at present cooperates with special-purpose dregs bucket, will be transported to ground from the dregs that mine working goes out.The tipping bucket hook of transfer crane shedding mechanism is the hard hook of rigidity, can only export dregs at standing height, and the operation operating mode is restricted.
The utility model content
The utility model is to the defective that present transfer crane shedding mechanism exists, provide a kind of can be in the lifting altitude scope shedding mechanism of optional position output dregs.
The utility model is installed on the dolly, comprises main hoisting mechanism, variable-frequency motor, winch, retarder, dregs bucket; Establish coder on the winch input shaft, following connection suspender, rope tool; The both sides upper longitudinal of dregs bucket to mid point the center hanger is set, the bottom is provided with eccentric hanger, the suspender cover of main hoisting mechanism hangs on the center hanger of dregs bucket, the upper end of winch rope tool is connected on the suspender, the lower end cover hangs on the eccentric hanger of dregs bucket.
The quantity of said variable-frequency motor is one, and the quantity of winch is two, and variable-frequency motor drives two winchs simultaneously through transmission shaft and retarder.
The clear superiority of the utility model is:
1, utilize the attaching parts between winch and the dregs bucket to be suspender and rope tool, its rope capacity scalable, but can guarantee the optional position tipping bucket discharging of dregs bucket in the lifting altitude scope, adaptability for working condition is strong;
2, the rope tool of winch upper end is connected with suspender, and the lower end cover hangs on the dregs bucket, and entire work process need not withdraw from it; Saved the hard hook hook of rigidity and the action of breaking off relations; The tipping bucket discharging is safety more flexibly and fast, has improved work efficiency, has alleviated driver's working strength.
Description of drawings
Fig. 1 looks scheme drawing for the master of the utility model.
Fig. 2 looks scheme drawing for the left side of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is installed on the dolly 8, comprises main hoisting mechanism 1, variable-frequency motor 2, winch 3, transmission shaft 7, retarder 5, dregs bucket 4.Rope tool 32 upper ends are connected on the suspender 31, and the lower end cover hangs on the eccentric hanger 42 of dregs bucket 4 bottoms.Winch 3 goes up and down dregs bucket 4 through suspender 31, rope tool 32.Suspender 11 covers of main hoisting mechanism 1 hang over dregs bucket 4 upper longitudinal on the center of mid point hanger 41; Select the transmitting ratio of the retarder 5 of driving winch 3; The highest lifting velocity that guarantees winch 3 is identical with the highest lifting velocity of main hoisting mechanism 1; Regulate variable-frequency motor 2 through the frequency converter in coder 33 regulation and control systems again; Make two winchs 3 consistent, start the steady up-down that winch 3 and main hoisting mechanism 1 can guarantee dregs bucket 4 during work simultaneously with the lifting action of main hoisting mechanism 1.During the dregs overturning, winch 3 is through drg 6 brakings, and main hoisting mechanism 1 descends, and the dregs bucket is to overturn to the lower left in the center of circle with eccentric hanger 42, realizes the dregs overturning.After the dregs overturning finished, main hoisting mechanism 1 rose, and makes dregs bucket 4 be positioned at shown position, started main hoisting mechanism 1 once more and with hoisting machine 3 the dregs bucket was descended, and accomplished a working cycle.
