Abstract
The utility model discloses a large upper opening type side fan-shaped door crank track unloading skip, and belongs to a lift coal skip. The skip box of the skip is arranged inside the frame; a coal-unloading port is arranged at the side face at lower part of the skip box and is provided with an unloading gate; a fixing curve track is arranged on the derrick; side fan-shaped structure is adopted for the unloading gate; a revolving shaft sleeve is respectively arranged at upper part of two fan-shaped side plates; an arc plate is arranged between left lower parts; an unloading shaft is arranged at right lower part; unloading rollers are arranged at both ends of the unloading shaft; a sloping linear tank rail is arranged for the crank track; a linear tank rail is respective at the upper and the lower ends of the sloping linear tank rail. When the skip runs to the crank track position, the unloading roller at the lower part of the unloading gate enters the crank track; the skip continues to move upward, the unloading roller moves according to the track of the crank track to open the unloading gate upward, making stored coal unloaded inside the skip box; after unloading is finished, the skip box moves downward, the unloading roller returns according to the track of the crank track to close the unloading gate forward. The skip has the advantages of simple structure, quickly and stably unloading, no coal loss and high safety and reliability.
Description
Technical field
The utility model relates to a kind of coal skip bucket of carrying, specifically a kind of large-scale open type side fan-shaped gate curve trail load skip bucket of going up.
Background technology
At present, in the large-scale skip bucket more than 20 tons, outer power unloading manner is all adopted in its unloading, promptly adopts cylinder or hydraulic actuating cylinder to open the skip bucket gate, and its shortcoming is: the unloading stop time grows that discharge rate is slow, equipment investment is big, fault is many, safe reliability is poor, complex structure, maintenance workload are big.
A kind of coal skip bucket of carrying is arranged, and this skip bucket has a framework, and framework is made of last dish, column and lower wall, and column is between last dish and lower wall, and the bucket case places framework, and circular arc unloading gate is installed bend on derrick at the bottom of the back open type is installed in the bottom of bucket case; The unloading gate has two side plates, and swivel sleeve is arranged at side plate top, and arc plate is arranged at the side plate bottom, and the unloading axle is arranged under the arc plate, and there is unloading roller at unloading axle two ends; Bend has skew lines grooved track, at the upper/lower terminal of skew lines grooved track one straight-line groove type track is arranged respectively, and straight line grooved track all is connected with skew lines grooved track by the camber track.Because the unloading gate of this skip bucket is mounted in the bottom of bucket case, the weight of the coal in the bucket case all is applied on the unloading gate, make the unloading pressure that gate bore too big, thereby it is big during unloading to the impact of bend and derrick, in addition, because the unloading gate is installed in the bottom of bucket case, can produce when unloading coal and spill the coal phenomenon.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, unloading quick and stable, peace can the higher large-scale open type side fan-shaped gate curve trail load skip buckets of going up of reliability.
The purpose of this utility model is achieved in that the lower side at the bucket case is provided with coal unloading hole, and the unloading gate is equipped with at the coal unloading hole place; The unloading gate adopts the side sector structure, and two fan-shaped side plates are arranged, and a swivel sleeve is respectively arranged at the top of biside plate, is connected by arc plate between the side plate, and arc plate is positioned at an end of side plate, and the unloading axle is positioned at the other end of side plate, and there is unloading roller at unloading axle two ends.
Beneficial effect: owing to adopt such scheme, when skip bucket ran to the bend position, the unloading roller of unloading both sides, gate bottom all entered the bend of a side separately, and skip bucket continues upward movement, and unloading roller is pressed the bend orbiting motion, will unload gate and upwards open; After the completion of discharge, skip bucket moves downward, and unloading roller returns by the bend track, and will unload gate and close downwards, thus the automation of realization dustpan unloading.Simultaneously, the unloading gate adopts the side sector structure, effectively alleviated in the bucket case storage coal to the pressure of gate, thereby reduced the gate opening resistance, when both having reduced unloading to the impulsive force of bend and derrick.In addition, the skip bucket coal unloading hole is arranged in bucket lower box part side, can make unloading coal stream form parabola, reduces and spills coal.This skip bucket is simple in structure, the unloading quick and stable, and the safe reliability height has reached the purpose of this utility model.

The specific embodiment
Embodiment: in Fig. 1: a kind of large-scale open type side fan-shaped gate curve trail load skip bucket of going up, the top of last dish 1 is connected with steel-cable suspensioning device, two or four root posts 2 are installed in the both sides of last dish 1, and column 2 fixes by modes such as riveting, weldering or bolt and bucket case 3 and lower wall 6; In the bottom of bucket case 3 unloading gate 4 is installed, unloading gate 4 is connected with bucket case 3 by anchor shaft 5, and unloading gate 4 can rotate around anchor shaft 5.Simultaneously, two bends 7 are installed on derrick, when the skip bucket up-and-down movement, two unloading rollers on the unloading gate 4 move in bend 7, thereby open or close unloading gate 4, reach and finish discharged purpose.
In Fig. 2, among Fig. 3: bend has skew lines grooved track, at the upper/lower terminal of skew lines grooved track one straight-line groove type track is arranged respectively, and straight line grooved track all is connected with skew lines grooved track by the camber track.Bend 7 is made up of base plate 13, right riser 14 and left riser 15, base plate 13 links with derrick, right riser 14 and left riser 15 are welded on more than the base plate and form groove, the segment of curve of right riser 14 and left riser 15 constitutes by two circular arcs that differ in size up and down and skew lines, can avoid the dead point, unloading pulley 12 is moved in groove steadily.
In Fig. 4, Fig. 5: unloading gate 4 mainly is made up of side plate 8, arc plate 9, axle sleeve 10, unloading axle 11 and unloading roller 12.Arc plate 9 is installed between biside plate 8, and the top of side plate 8 is equipped with two axle sleeves 10, and by axle sleeve 10, unloading gate 4 can rotate around anchor shaft 5; The lower left quarter of biside plate 8 is equipped with unloading axle 11, and unloading roller 12 is installed in the two ends of unloading axle 11, when unloading roller 12 moves in bend 7, can drive gate 4 and upwards open or close downwards.
