Abstract

A skip hoist with simple structure, small amount of maintenance, and automatic unload is provided, which comprises a derrick frame, a skip, a curve rail, an idle wheel, a wire rope, a hoister, a counter, as well as a cellar, wherein the skip outlet hole is equipped with an arc-like gate, a tongue plate, and two rolling wheels, the upper part inner side of the derrick frame is connected with two curve rails and is opposite to positions of the two rolling wheels on skip in the derrick fame, and the derrick frame outer side is fixed with a hoister. The skip hoist adopts a control circuit that can inversely start and automatically stop with limit switch, which is used for hoisting materials in electric power plant, cement plant, as well as sand yard. The skip hoist is also has the characteristics of small investment, easy manufacture, small floor area, which can be calculated.

Description

Skip hoist

Affiliated technical field

The utility model relates to a kind of device of carrying dispersed material of going straight up to, especially have simple in structure, maintenance is little and the skip hoist of automatic discharging.

Background technology

Present existing bucket elevator, it has floor area little than band conveyor, invests less advantage, but it also exists structure complicated, and material spilling is serious, and hopper and drive disk assembly are easy to wear, and maintenance is big, does not have the deficiency of metering.

Summary of the invention

Have the deficiency that structure is complicated, maintenance is big in order to overcome existing bucket elevator, the purpose of this utility model provide a kind of have single between structure, maintenance is little and the skip hoist of automatic discharging.

The utility model technical scheme that is adopted of dealing with problems is: it is made up of derrick, skip bucket, bend, pulley, steel rope, winch, counting machine and melt pit, wherein the skip bucket discharging opening is provided with a gates of segmental shape, a tongue is pulled and two rollers, two bends of side connection are corresponding with two roller positions on the interior skip bucket of derrick in the derrick top, and the outer side of derrick is fixed a winch.It is lifting means that this gig adopts a skip bucket charging and winch steel rope, so structure is very simple, wearing parts seldom, when skip bucket rises to bend, two rollers enter bend, track by bend inwardly promotes, gates of segmental shape is rotated up open discharging opening simultaneously tongue pull and release and sagging guiding Flow of Goods and Materials; Leave bend when skip bucket two rollers that fall again, rely on the gates of segmental shape self gravitation, gates of segmental shape, tongue are pulled with two rollers resetted.Thereby reach the utility model have simple in structure, maintenance is little and the purpose of automatic discharging.

The utility model beneficial effect be have simple in structure, maintenance is little, also have small investment automatic discharging the time, easy to manufacture, floor area is little, measurable.

Supplemental instruction

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structure figure of the utility model embodiment.

Among the figure 1, derrick 1-1, guide rail 2, pulley 3, skip bucket 3-1, buting iron 3-2, bucket body 3-3, gates of segmental shape 3-4, pin 3-5, roller 3-6, tongue pull 3-7, idler pulley 3-8, guide wheel 4, bend 5, steel rope 6, winch 7, counting machine 8, melt pit 8-1, funnel ZC, FC, just, reverse contactless switch ZXK, FXK, just, reverse stroke switch D, electrical motor ZA, FA just, reverse starter button TA, stop button

The specific embodiment

In Fig. 1,2,3 illustrated embodiments, at derrick (1) two inboard middle two guide rails (1-1) that are provided with; One outside wire rope hoist (6) sum counter (7); Top one inboard two bends (4) that connect; The top connects two pulleys (2) and a forward stroke switch (ZXK); The bottom connects a reverse stroke switch (FXK); Derrick (1) is fixing is employed above the melt pit (8), and melt pit (8) one sides are provided with a loading hopper (8-1), and skip bucket (3) is feeded in melt pit (8).It is provided with by the discharging opening of bucket body (3-2) side that a gates of segmental shape (3-3) flexibly connects by pin (3-4) and bucket body (3-2) and a tongue is pulled (3-6) on idler pulley (3-7) and gates of segmental shape (3-3) flexible connection skip bucket; Two rollers (3-5) also flexibly connect with gates of segmental shape (3-3); Upper and lower two sides of bucket body (3-2) respectively connect four guide wheels (3-8); Bucket body (3-2) top connects; Buting iron (3-1) is formed.Steel rope (5) on the winch (6) passes two pulleys (2) and is connected with skip bucket (3).When skip bucket (3) rose to bend (4), two rollers (3-5) entered bend (4), inwardly promoted, and gates of segmental shape (3-3) is rotated up discharging opening open simultaneously tongue and pull (3-6) and release and sagging guiding Flow of Goods and Materials; Work as skip bucket (3) two rollers of decline (3-5) again and leave bend, rely on gates of segmental shape (3-3) self gravitation that gates of segmental shape (3-3), tongue are pulled (3-6), two rollers (3-5) reset.Counting machine (7) adopts the Huo Shi sensor.This skip hoist also have small investment, easy to manufacture, floor area is little, measurable.

Shown in Fig. 4, this electric control circuit is the self-braking control circuit of reversible starting travel switch, its principle of work: when pressing forward or reverse starter button (ZA), (FA), forward or reverse contactless switch (ZC) (FC) start after, electrical motor (D) makes forward or reverse running drive buting iron (3-1) is done respectively, move down, stir forward or reverse stroke switch (ZXK) and (FXK) make normally closed interlock (ZXK) or (FXK) disconnect when walking to assigned position buting iron (3-1), corresponding reverse contactless switch of forward (ZC) or (FC) release, electrical motor (D) shuts down, need stop transport can be by stop button (TA) midway, normally closed interlock (FC) or (ZC) just can prevent, reverse contactless switch (ZC) is starting simultaneously (FC), plays chain effect.

Claims

A skip hoist it form by derrick, skip bucket, bend, pulley, steel rope, winch, counting machine and melt pit, it is characterized in that: the skip bucket discharging opening is provided with a gates of segmental shape, a tongue is pulled and two rollers, two bends of side connection are corresponding with two roller positions on the interior skip bucket of derrick in the derrick top, and the outer side of derrick is fixed a winch.
