Description
Technical field
The utility model relates to the multi-functional killer of a kind of winch.
Background technology
Existing cargo lift, mining following problem occurs with the elevator cage and the winch of digging up mine with mine car in the long-term use process: 1, no overload protection.Rise article when overweight when winch hangs, still work on, thereby, with the burn-down of electric motor of winch; 2, after the cage of winch lands, winch still continues to put rope, causes the long appearance of steel rope to twine the situation of beating strand each other.
The utility model content
The purpose of the utility model provides the multi-functional killer of a kind of winch, and it both can have been controlled winch and shut down when overweight, the motor of protection winch; Again can be after hanging object or cage land; In time the control winch is shut down, and prevents that steel rope is long, avoids steel rope to beat strand.Thereby, can solve the problem that prior art exists.
The utility model is realized through following technical scheme for realizing above-mentioned purpose: the multi-functional killer of winch, comprise housing, and the movable lower connecting rod of installing in the housing, lifter plate is installed on the top of lower connecting rod; The lower end of lower connecting rod passes outside the housing; The periphery of lower connecting rod is installed first spring, and first spring is positioned at housing, side contacts in the first spring lower end and the housing base plate, and the top of first spring contacts with lifter plate; Install sensor and lower sensor in the housing, upper sensor is positioned at the lifter plate top, and lower sensor is positioned at the lifter plate below; The interior week or the periphery of first spring are pacified second spring, and second spring is positioned at housing, side contacts in the lower end of second spring and the housing base plate; The length of first spring is greater than the length of second spring.
In order further to realize the purpose of the utility model, can also adopt following technical scheme: guide pillar is installed in the said housing, is offered pilot hole on the lifter plate, guide pillar cooperates with pilot hole lower connecting rod is play the guiding role.Said housing is connected and composed by upper plate, lower plate and shell; Upper plate is connected fixing with lower plate through shell; Offer through hole on the lower plate, through hole cooperates with lower connecting rod is movable.Said upper sensor and lower sensor are near switch or travel switch.
The advantage of the utility model is: it is equipped with upper sensor, lower sensor, lower connecting rod and first spring.When hanging object was overweight, lower sensor sent the signal control winch and shuts down; When cage landed, upper sensor control winch was shut down, thereby, both can protect the safety of winch motor, can prevent the situation that steel rope is crossed the long dozen strand again.The utility model also has compactness simple for structure, advantage cheap for manufacturing cost and easy to use.
Description of drawings
Fig. 1 is the structural representation of the multi-functional killer of the said winch of the utility model; Fig. 2 is the A-A line sectional structure scheme drawing along Fig. 1; Fig. 3 is the B-B line sectional structure scheme drawing along Fig. 1.
Reference numeral: 1 upper connecting rod, 2 lower connecting rods, 3 fixed blocks, 4 lifter plates, 5 guide pillars, 6 pilot holes, 7 nuts, 8 upper plates, 9 lower plates, 10 first springs, 11 second springs, 12 upper sensors, 13 lower sensors, 14 shells, 15 through holes.
The specific embodiment
The multi-functional killer of the described winch of the utility model comprises housing, the movable lower connecting rod 2 of installing in the housing.As shown in Figure 1, lifter plate 4 is installed on the top of lower connecting rod 2.The lower end of lower connecting rod 2 passes outside the housing.The periphery of lower connecting rod 2 is installed first spring, 10, the first springs 10 and is positioned at housing.Side contacts in first spring, 10 lower ends and the housing base plate, the top of first spring 10 contacts with lifter plate 4.Install sensor 12 and lower sensor 13 in the housing, upper sensor 12 is positioned at lifter plate 4 tops, and lower sensor 13 is positioned at lifter plate 4 belows.The interior week of first spring 10 or periphery are pacified second spring, 11, the second springs 11 and are positioned at housing, side contacts in the lower end of second spring 11 and the housing base plate.The length of first spring 10 is greater than the length of second spring 11.Said first spring 10 makes lifter plate 4 that the trend near upper sensor 12 arranged all the time for lifter plate 4 provides upwards predetermincd tension.Described first spring 10 and second spring 11 all can be substituted by existing other elastic components, but, can know that through experiment the result of use of other elastic components is not as first spring 10 and second spring, 11 ideals.Can be provided with upper connecting rod 1 on the housing, so that be connected fixing with steel rope.Fix for easy of rise plate 4 is connected with lower connecting rod 2, fixed block 3 is installed on the lower connecting rod 2.
During work, earlier said upper connecting rod 1 is connected with the work body, lower connecting rod 2 is connected fixing with the winch steel rope, and cage is connected cooperation through movable pulley with the winch steel rope; Restart winch; When hanging object is overweight; Lower connecting rod 2 can pulling lifter plates 4 overcomes the elastic force of first spring 10 earlier, overcomes first spring 10 again with second spring, 11 common elastic force move down, when lifter plate 4 and lower sensor 13 are touched or sensed lifter plate 4; Lower sensor 13 is to the control setup give a signal, and control setup is shut down winch; After cage lands; Lower connecting rod 2 loses pulling force, and lower connecting rod 2 moves up under the effect of first spring 10 with lifter plate 4, when upper sensor 12 is touched or sensed lifter plate 4; Upper sensor 12 is to the control setup give a signal, and control setup is shut down winch.
For ease of processing and manufacturing, as shown in Figure 1, said housing can be connected and composed by upper plate 8, lower plate 9 and shell 14.Upper plate 8 is connected fixing with lower plate 9 through shell 14.Offer through hole 15 on the lower plate 9, through hole 15 and 2 movable cooperations of lower connecting rod.
Said upper sensor 12 can be existing near switch or travel switch with lower sensor 13.As shown in Figure 2, guide pillar 5 is installed in the said housing, offer pilot hole 6 on the lifter plate 4, guide pillar 5 cooperates with pilot hole 6 lower connecting rod 2 is play the guiding role.The utility model not part of detailed description is known technology.
