Abstract
The utility model discloses a bottom dumping device for the unloading of mine hoist skip, which conducts the improvement based on the original dumping device consisting of a fan shaped strobe(3), an idler wheel(5), a strobe shaft component(2), a dumping scroll(4) and so on. One side of a fan shaped plate(11) of the fan shaped strobe(3) is provided additionally with a buffering device so as to reduce the impact when opening and closing. Upper end of the fan shaped strobe(3) is connected with a skip through the strobe shaft component(2), and an arched plate(2) on the lower end covers a discharge opening of the skip, which increase the rotary force. The strobe shaft component(2) is in a joint bearing structure, and a central line of a lower straight rail(9) of the dumping scroll(4) is overlapped with the hoisting central line of the idler wheel, therefore, the utility model is characterized in that the fan shaped strobe(3) has small impact when opening and closing, small rotary resistance, good self locking performance, security and reliability and quick dumping and so on.
Description
One, affiliated technical field
The utility model is the end handler that a kind of mine hoisting dustpan unloading is used.
Two, background technology
At present, industries such as colliery, metallurgy promote gate and the curve trail load mode of using on the skip bucket, are to go up the open architecture form.In use, have following shortcoming: during gate opening, rotary arm is short, and the gate opening resisting moment is big, and is big to the derrick impulsive force, safety misadventure often occurs; Simultaneously, because shutter mass centre departs from the lifting line of centers, cause the skip bucket deflection, in service, skip bucket, cage shoe are fragile, thereby have seriously restricted the main shaft hooist ability, and influence the safe operation of elevator system.
Three, summary of the invention
The purpose of this utility model is that the gate opening resistance of this device is little for the unloading that promotes skip bucket provides handler of a kind of end, and self-locking property is good; The skip bucket outside can be do not given prominence to after gate is opened yet, thereby the unloading accident can not be occurred; The skip end opening does not need to close up yet, and helps unloading, can guarantee the unloading time requirement, is a kind of safe and reliable, unloads handler at the bottom of the fast novel skip bucket.
For achieving the above object, the technical scheme that the utility model is taked is: the discharging gear to former skip bucket improves, and is made up of sector gate, roller, gate Shaft assembly, dump rail etc.Be provided with cushion rubber by a side that contacts with skip on the quadrant of sector gate.The gate Shaft assembly is the oscillating bearing structure.Dump rail is
Shape, be that dump rail includes exit skirt, last straight rail, oblique rail, lower and straight track, following exit skirt etc. partly, the upper end of going up straight rail is last exit skirt, the lower end of lower and straight track is by garden curved track and tiltedly rail coupling, tiltedly the lower end of rail connects with lower and straight track by the garden curved track, and the lower end of lower and straight track is following exit skirt.The upper end of sector gate connects with skip bucket by the gate Shaft assembly, the arc of sector gate lower end covers the discharge port of skip bucket lower end, roller is placed in the dump rail, and roller also is installed in bottom on the quadrant of sector gate near the arc place by its roller shaft.Dump rail is fixed on the derrick, its lower and straight track line of centers and roller promote central lines.
The skip bucket that to fill special material when gig slowly rises and when unloading, roller enters lower and straight track through the following exit skirt of dump rail earlier, enter straight rail by lower and straight track through oblique rail again, this moment is in the guiding of dump rail and suppress down, is that the discharge port that the skip bucket bottom is opened in middle mind-set one sideway swivel unloads with the sector gate Shaft assembly.
Because the center of gravity of sector gate near the skip hoisting line of centers, can not cause the deflection of skip bucket; Roller is arranged near the arc place, and the rotary arm of the sector gate that extended has reduced the resisting moment that sector gate is opened, and set up cushion rubber on the quadrant of sector gate, when having reduced the sector gate opening and closing to the impulsive force of skip bucket, derrick.The gate Shaft assembly adopts the oscillating bearing structure, can avoid the influence of skip bucket distortion to the gate flexible movements; Can not give prominence to the skip bucket outside when sector gate is opened simultaneously yet; Sector gate can not opened under deadweight and material action of gravity voluntarily, and self-locking property is good; Between the last straight rail of dump rail and oblique rail, oblique rail and the lower and straight track all are garden arc transition, and roller moves in dump rail and can not take place to impact and the dead point phenomenon.Characteristics such as impulsive force is little when therefore the utlity model has opening and closing, and the rotational resistance square is little, and self-locking property is good, and safe and reliable, unloading is fast.

Fig. 3 is the utility model sector gate scheme drawing.
Five, specific implementation method
As shown in the figure, the utility model is made up of sector gate (3), roller (5), gate Shaft assembly (2), dump rail (4) etc.Sector gate (3) is formed the main body of sector gate (3) by an arc (12), two quadrants (11), is provided with bump rubber (13) on the side that contacts with skip in the left side of quadrant (11).Bump rubber (13) can be a rubber pad, to reduce sector gate (3) impulsive force to skip bucket, derrick (1) when closing.The arc (12) of sector gate (3) lower end covers the discharge port of skip bucket lower end, and the upper end of sector gate (3) is installed on the skip bucket by gate Shaft assembly (2).Gate Shaft assembly (2) is the oscillating bearing structure, influences the opening and closing of sector gate (3) to the skip bucket discharge port to avoid the skip bucket distortion.Roller (5) is placed in the dump rail (4), and roller (5) also is installed in last, the also close arc (12) of quadrant (11) of sector gate (3) by its roller shaft.Dump rail (4) be fixed on the derrick (1) with the corresponding position of roller (5).Dump rail (4) includes exit skirt (6), last straight rail (7), oblique rail (8), lower and straight track (9), following exit skirt (10) etc. partly, the upper end of going up straight rail (7) is last exit skirt (6), the lower end of going up straight rail (7) connects with oblique rail (8), tiltedly the lower end of rail (8) connects with lower and straight track (9), the lower end of lower and straight track (9) is following exit skirt (10), go up straight rail (7) and tiltedly be garden arc transition between rail (8), oblique rail (8) and the lower and straight track (9), its lower and straight track (9) line of centers and roller (5) promote central lines.When roller (5) slowly moves from bottom to top, exit skirt (10) enters lower and straight track (9) under the warp earlier, again through the oblique supreme straight rail of rail (8) (7), in the guiding of dump rail (4) pair roller (5) with suppress down, the discharge port of sector gate (3) being opened skip bucket unloads, and can not impact, the dead point.Sector gate (3) also can not be given prominence to the gabarit of skip bucket.Characteristics such as impulsive force is little when therefore the utlity model has opening and closing, and the rotational resistance square is little, and self-locking property is good, and safe and reliable, unloading is fast.
