Description

The dregs bucket tipping device

Technical field

The utility model belongs to subway work and uses elevator machinery, relates to a kind of pure mechanically operated dregs bucket tipping device.

Background technology

Be used for main gantry crane or the crawler crane of adopting of subway work dregs output at present and cooperate, will be transported to ground from the dregs that mine working goes out with special-purpose dregs bucket.Because of adopting crawler crane output dregs, its employable dregs bucket capacity of institute is long-pending less, and operating efficiency is low, and energy consumption is big, and cost is high.Adopt gantry crane output dregs at present mostly; It mainly is that the employed dregs bucket capacity of gantry crane is long-pending bigger; Operating efficiency is high; But the present dregs way of output is two kinds basically: a kind of is that suspension hook is realized tipping bucket with artificial the cooperation, and another kind is to carry out tipping bucket in certain fixed position with special-purpose bucket tipping device or hydraulic pressure bucket tipping device, and dregs in the dregs bucket is poured out.The defective of this dual mode is: need artificial the extension unload the tipping bucket hook when using the suspension hook tipping bucket, this mode not only efficient is low and have certain potential safety hazard; Adopt special-purpose bucket tipping device in certain fixed position during tipping bucket; Because of this device generally is installed on a certain ground of the gantry crane crossbeam; The dregs bucket must be transported to gantry crane girder end through dolly just can carry out tipping bucket; If in the time of need carrying out dregs output in other position, can't realize that then in use there is certain limitation in this mode; Adopting the hydraulic pressure bucket tipping device to carry out tipping bucket then needs special hydraulic efficiency pressure system, cost higher.

The utility model content

The purpose of the utility model is the defective that exists to the present subway work dregs way of output, and a kind of pure mechanically operated dregs bucket tipping device of simple in structure, low cost of manufacture is provided.

The utility model comprises dolly, dregs bucket and shedding mechanism, and the structure of shedding mechanism mainly comprises mainboard hook, hanging beam, tipping bucket hook, main hoisting drum, retarder, electrical motor, slide, leading screw, dental type coupling, fixed guide; Said shedding mechanism is installed on the dolly.

Said tipping bucket hook is connected with slide lower end otic placode through bearing pin, and the tipping bucket hook can swing around bearing pin, during with the release tipping bucket from the part of horizontal application force of dregs bucket.

Said tipping bucket hook structure can be the polylith plate hook and is formed by stacking, or epimere is the box type construction of square-section, and hypomere is the variable section structure of plate hook, and tipping bucket hook stability is with stressed good when making tipping bucket.

Said slide is the box type construction that steel plate weldering knot forms, and Stability Analysis of Structures is stressed good.

Connecting rod all is set between the said slide and between the tipping bucket hook, and adopts flange to connect, make slide become as a whole with the tipping bucket hook, strengthen the integral rigidity and the synchronized movement property of structure, the flange connection is convenient, and scalable also reduces transport difficulty simultaneously.

In the said slide guide pin bushing is installed, trapezoidal or square thread is connected for coarse-pitch between guide pin bushing and the leading screw, makes leading screw pass to slide synchronously from the power of retarder.

The lower end otic placode arranged outside movable guiding rail of said slide, its cross section is a reversed convex type, is that the fixed guide of spill cooperates with the cross section, the cross section after the cooperation is a rectangle, guarantees the straightness accuracy of whole guide rail, and slide is operated steadily.

Said electrical motor adopts the variable ratio frequency changer electrical motor of band brake, and the tipping bucket hook unloads synchronism through variable frequency control, and its frequency converter can be shared with other actuating mechanism.

The two ends of said fixed guide are provided with travel switch, the accurate position that control tipping bucket hook unloads.

Compared with prior art, the advantage of the utility model is:

1, the tipping bucket hook is hung automatically and is unloaded the dregs bucket;

2, the automatic overturning dregs of tipping bucket hook bucket;

3, shedding mechanism is installed on the dolly, can realize the dregs output of optional position, high efficiency;

4, adopt pure mechanical drive, simple in structure, cost is low, fault rate is low, easy to maintenance succinct, safe and reliable.
