Abstract
The utility model belongs to the transport machinery, and can realize the middle-long distance forward and reverse load carrying run in the hauling operation of winches, the decrease of the abrasion of steel cables and the elimination of the lateral swing of ropes when the winches run. According to the size of the traction force, the utility model, which can be used in the places of power plants, quays, coal mines, etc., where long range traction hauling operation is needed, can be classified into a plurality of model numbers of 8 ton, 15 ton, 30 ton, 50 ton, etc. The utility model is mainly technically characterized in that two reels are adopted to rotate, rope slots on the two reels are dislocated mutually with the distance of a pitch, and the rope grooves are circumferential straight slots.
Description
This novel Transport Machinery that belongs to.
This later-model purpose is to solve long wearing and tearing apart from steel rope in the traction winch, teeter and two-way tape load transmission problem.
This novel scheme that in design, adopts two driven gear transmissions of a driving gear drive.See mark among Fig. 1, the 2:(figure: 1, driver pinion; 2, the driven big gear wheel of left end; 3, the driven big gear wheel of right-hand member; 4, steel rope; 5, reel) two reels are separately fixed on two driven big gear wheels, and 5 road groovings (circumference straight trough) are arranged on each reel.5 road groovings on first reel have a little angle to change α with respect to 5 road groovings on second reel, and this angle [alpha] has formed the distance of a slot pitch just.See Fig. 3: (mark among the figure: a, slot pitch; B, drum diameter; C, drum diameter; And the b=c) calculating of α:
α＝arccos (b
2+c
2-a
2)/(2bc) ＝arccos (2b
2-a
2)/(2b
2)
When driving gear rotated, two driven gears produced simultaneously in the same way and rotate.And be fixed on two reels on the driven gear also is to rotate in the same way.Again because of the slot pitch of the relative changing of the relative positions of grooving on two reels, so steel rope is walked around 180 ° of second road grooves that enter on first reel again after entering second a groove bottom on the reel by a groove bottom on first reel.Each fixedly moves in the grooving at it in operational process to reach steel rope with this rule, has avoided the phase mutual interference and the wearing and tearing that endwisely slip.Its wiring rule scheme drawing is seen Fig. 4.
Because be two reel transmissions, actual wiring is 4 circles, and its cornerite is 4 * 2 π, can not produce skidding basically.And the circumferential relative wear of steel rope and reel face is eliminated.(having only wriggling)
Because driving gear and one of them driven gear have the variation of angle [alpha], helical angle is unequal and in fact become spiral gear in design.(the tooth oblique angle of establishing driver pinion is β, and the tooth oblique angle of right-hand member big gear wheel also is β, the tooth oblique angle of left end big gear wheel be β+α) but the angle of α very little (＜4 °) so in transmission intensity and the life-span influence to gear little.
In system layout, adopt two-way tension can realize the bi-directional load.Plan sketch is seen Fig. 5: (mark among the figure: 6, winch; 7, track adjusting wheel; 8, tensioning dolly; 9, counterweight; 10, traction car pusher; 4, steel rope) the required counterweight of tensioning dolly is all calculated by the slack list tensile force.
Winch is divided into several models such as 8 tons, 15 tons, 30 tons, 50 tons according to the size of tractive force.
Present traction has two major types with winch: utmost point rope winch and endless rope winch are arranged, have utmost point rope winch only to be applicable to short range transmission (in about 100 meters).And the side travel amount is very big in the steel rope winding process, the serious wear between rope and the carrying roller.Endless rope winch is applicable to long apart from transmission.But existing endless rope winch mostly is single drum lateral compression slippage canoe.In transmission, because the steel rope lateral compression, and slippage on reel, easily producing folded rope phenomenon, rope has teeter, easily causes rope to break away from carrying roller.And serious wear, unfavorable to moving.Above-mentioned phenomenon more very, therefore often can not back transfer be loaded when the winch reverse drive.And this later-model " endless rope winch of double drums and vertical groove type " both can forward and reverse transfer charge, and the wearing and tearing of steel rope and reel are alleviated, and had also eliminated the teeter of rope.Help system's operation.Have the advantage that utmost point rope winch and endless rope winch are arranged concurrently, avoided their shortcoming.The place that needs to transport, dispatch goods applicable to power plant, harbour, mine etc.
Claims (1)
1, endless rope winch of double drums and vertical groove type.Can two-way (forward and reverse) tracted load.This winch has 1, two of a driver pinion to have the driven big gear wheel 2 and 3 (see figure 1)s of reel 5 respectively.And the grooving (circumference straight trough) that all has 5 roads to equate on each reel.It is characterized in that: driven big gear wheel 2 has a little angle to change α with respect to driven big gear wheel 3.This angle [alpha] makes the distance of a slot pitch of two drum rope groove tops (or bottom) changing of the relative positions just.
