Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As Figure 1-3, a kind of lowering or hoisting gear of automatic airer, comprise the first fixed mount 20, second fixed mount 30, first winder 23, second winder 24, two tension force holding device 21, transformer 26, receiver of remote-control sytem 28, first cable wire 3, second cable wire 27 and motor 22, described first winder 23 and the second winder 24 are fixed on the first fixed mount 20, first winder 23 and the second winder 24 are in transmission connection by change-speed gearing 25, and motor 22 is fixed on the first winder 23 and the second winder 24 in the mode be in transmission connection.
Transformer 26 and receiver of remote-control sytem 28 are fixed on the second fixed mount 30, two tension force holding devices 21 are fixed on the first fixed mount 20 and the second fixed mount 30 respectively, a fixed pulley 2 is fixed with respectively in two tension force holding devices 21, two tension force holding devices 21 are installed with respectively and the first winder 23 and the just right horizontally tracting mouth 61 of the second winder 24, first cable wire 3 is by horizontally tracting mouth 61 solderless wrapped connection on the first fixed mount 20 in the race of the fixed pulley 2 of the first fixed mount 20 and on the wheel shaft of the first winder 23, second cable wire 27 is by horizontally tracting mouth 61 solderless wrapped connection on the second fixed mount 30 in the race of the fixed pulley 2 of the second fixed mount 30 and on the wheel shaft of the second winder 24.
By this, by two prefabricated the first fixed mount 20 and the second fixed mounts 30, by the motor 22, fixed pulley 2, winder, transformer 26 and other related accessory integrated installations that are installed separately before on two fixed mounts, the structure of producing component is simple, save the operation sequence of installation and removal, be convenient to install, cost-saving, the production budget of producer is reduced, the valency of purchasing of user is more cheap and convenient, simultaneously the spacing of two fixed mounts can according to the actual using area of user independently control, practical.
Tension force holding device 21 as Figure 4-Figure 6, comprise fixture 1, upper axle 4, lower shaft 5, fixed pulley 2, flexible member and cable wire 3, fixture 1 comprises base plate 12, mount pad 11 and protective cover 6, mount pad 11 is vertically fixed on base plate 12, mount pad 11 is provided with two third through-holes 111 for fixing above axle 4 and lower shaft 5 and fourth hole 112, fixed pulley 2 to be assemblied on lower shaft 5 and to be positioned at protective cover 6, upper axle 4 and lower shaft 5 are each passed through third through-hole 111 and fourth hole 112 is affixed removably with mount pad 11, fourth hole 112 is elongated, cable wire 3 solderless wrapped connection is in the race of fixed pulley 2, cable wire 3 is straight down from horizontal direction pile warp fixed pulley 2 rear steering.
As shown in Figure 4; protective cover 6 is affixed with mount pad 11 removably; usually we use the mode of bolt and nut to be tightened; fixed pulley 2 is positioned at protective cover 6; this protective cover 6 be provided with the horizontally tracting mouth 61 and vertical traction mouth 62 that pass in and out for cable wire 3 and for fixing upper axle 4 and lower shaft 5 first through hole 63 and the second through hole 64, second through hole 64 elongated.
By the arranged outside protective cover 6 at fixed pulley 2; prevent because fixed pulley under External Force Acting 2 and cable wire 3 produce distortion and cannot use; improve the service life of fixed pulley 2 and cable wire 3; the described horizontally tracting mouth 61 for cable wire 3 turnover and vertical traction mouth 62 limit the scope of beating of cable wire 3 simultaneously, make the more difficult wire jumper of cable wire 3.
See Fig. 4 and Fig. 6; the outside of mount pad 11 and protective cover 6 is respectively equipped with spring 7; certainly; other flexible members that spring 7 can be arranged between axle 4 and lower shaft 5 for extension spring, Compress Spring, torsionspring and being applicable to; described upper axle 4 and the two ends of lower shaft 5 are respectively equipped with the first annular groove 8 circumferentially, and the two ends of spring 7 are connected in the first annular groove 8 of axle 4 and lower shaft 5 respectively.
As shown in Figure 7 and Figure 8; the two ends of described upper axle and 4 lower shafts 5 are respectively equipped with the second annular groove 9; second annular groove 9 is positioned at inside the first annular groove 8; and this second annular groove 9 lays respectively at the outside of protective cover 6 and mount pad 11; the spring leaf 10 for limiting upper axle 4 and lower shaft 5 axial displacement is respectively provided with in second annular groove 9; this spring leaf 10 is connected in the second annular groove 9; by such design; limit the axial displacement of axle 4 and lower shaft 5; prevent spring 7 from tilting to cause discontinuity equalization, make the more difficult wire jumper of cable wire 3.
The course of work of whole device is: when the tractive force of cable wire 3 is by little increase, due to the second through hole 64 and fourth hole 112 elongated, under the effect of tractive force, lower shaft 5 and fixed pulley 2 are pulled to the one end away from upper axle 4 by the one end near upper axle 4, spring 7 produces elastic resistance with the tractive force of cushioning balance cable wire 3, the tractive force of cable wire 3 is changed steadily slow down, prevent cable wire 3 wire jumper; In like manner, when the tractive force of cable wire 3 is by when reducing greatly, lower shaft 5 and fixed pulley 2 are pulled to one end of close upper axle 4 by the one end away from upper axle 4, spring 7 produces elastic resistance with the tractive force of cushioning balance cable wire 3, make the tension variation of cable wire 3 steady equally, prevent cable wire wire jumper.This also further avoid because of fixed pulley 2 lack of lubrication, cable wire 3 and fixed pulley 2 rub the reasons such as exception, cable wire 3 are aging cause drawing time tension force too small cable wire 3 wire jumper that makes, prevent cable wire 3 and fixed pulley 2 excessive compression from producing wearing and tearing, reduce the service life of cable wire 3 and fixed pulley 2.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
