The winding unit 31 of now take is located at link span 2 and is illustrated the working process of this actuating device 3 as example:
Adopt this structure, be rotated in the forward winding unit 31, so that traction element 32 is wound on winding unit 31, be that the length of traction element 32 between link span 2, bracing frame 1 reduces, and then the distance furthering between link span 2 tops, bracing frame 1, drive link span 2 upwards to rotate, and then spare tyre 100 is moved up from ground with respect to bracing frame 1.Contrarotation winding unit 31, discharges traction element 32, and the length between link span 2, bracing frame 1 increases, and is subject to the effect of weight of spare tyre 100, and spare tyre can move to ground from the top down gradually.
In scheme, in conjunction with Fig. 1 to Fig. 5, Fig. 3 is the structural representation of actuating device 3 in Fig. 1 more specifically, and Fig. 4, Fig. 5 are assembly drawing, the section-drawing of worm-and-wheel gear in Fig. 3; Link span 2 can swing up and down by horizontal bearing pin 21 with bracing frame 1, above-mentioned bracing frame 1 top is provided with fixed pulley 11, winding unit 31 is worm-and-wheel gear, worm-and-wheel gear is connected with link span 2 tops, comprise intermeshing worm screw 311, worm gear 312, worm screw 311 is connected with rocking handle 313, and the rotating shaft of worm gear 312 is connected with folding and unfolding wheel 314, and the rotating shaft of fixed pulley 11, folding and unfolding wheel 314 is all parallel with horizontal bearing pin 21; Traction element 32 is steel rope, and one end of steel rope is wound on folding and unfolding wheel 314, the other end is connected with link span 2, middle part is wound on fixed pulley 11.
Particularly, as shown in Figure 3, the first spacer 315 can be set, it is provided with the first chamber for accommodating worm gear 312, with the second chamber for accommodating worm screw 311, the bearing of trend of the first chamber, the second chamber vertically arranges, and worm gear 312 and worm screw 311 are installed in the first spacer 315, and the first spacer 315 is connected on link span 2 by threaded fasteners.In the first adjacent position of spacer 315, the second spacer 316 is set, folding and unfolding wheel 314 is installed in this spacer, and the rotating shaft of worm screw 311 is connected with folding and unfolding wheel 314 through the through hole 3142 of the second spacer 316 sidewalls.
As shown in Figure 6 and Figure 7, Fig. 6, Fig. 7 are front view, the side sectional view of folding and unfolding wheel 314 in Fig. 3; The sidewall of folding and unfolding wheel 314 is provided with degree of depth groove 3141 vertically, and folding and unfolding wheel 314 is provided with the through hole 3142 being parallel to radially, and this through hole 3142 is corresponding with groove 3141 bottoms, and groove 3141 bottoms are also provided with axially extended tapped bore 3143.In installation process, first through hole 3142 is passed in one end of steel rope, to put into groove 3141 with the compressing tablet of groove 3141 shape adaptations, again by being plugged in the screw-driving in tapped bore 3143, compressing tablet is fixed in groove 3141, compresses steel rope, realize steel rope and folding and unfolding and take turns 314 be connected.When like this, folding and unfolding wheel 314 rotates can by wire rope roll around or discharge.
Adopt this structure, forward shakes rocking handle 313, drive worm screw 311 to rotate, worm screw 311 drives the worm gear 312 being engaged with to rotate, worm gear 312 drives folding and unfolding wheel 314 synchronously to rotate, the steel rope one end being attached thereto is further wound on folding and unfolding wheel 314, thereby reduces the distance between bracing frame 1, link span 2, drive link span 2 upwards to rotate relative to bracing frame 1.Oppositely shake rocking handle 313, steel rope is released, and is subject to spare tyre effect of weight, and the relative bracing frame 1 of link span 2 rotates, and spare tyre is transferred.
The effect that there is reduction of speed and improve output torque due to worm-and-wheel gear, therefore adopt above-mentioned actuating device 3, operating personal is by shaking a less moment of torsion of rocking handle 313 outputs, just can increase output torque by worm-and-wheel gear, the spare tyre that weight is larger rises or transfers, and operating process is simple, convenient.
Can expect, the folding and unfolding wheel 314 that above-mentioned winding unit 31 is not limited in turbine and worm 311 mechanisms and is attached thereto, can also be made as other devices such as cylinder; Above-mentioned draw gear is also not limited in steel rope, can also adopt the miscellaneous parts such as chain.In addition, above-mentioned actuating device 3 is not also only for the mode of roll device and traction element 32 combinations, for example can replace with hydraulic actuating cylinder, by the cylinder barrel of hydraulic actuating cylinder, cylinder bar be connected with bracing frame 1 respectively, link span 2 tops connect, piston rod shortens can make the relative bracing frame 1 of link span 2 upwards swing, and piston rod extends and can make the relative bracing frame 1 of link span 2 to lower swing.
In the another kind of specific embodiment, as shown in Figure 3 and Figure 4, above-mentioned rocking handle 313 can eccentric setting with the rotating shaft of worm screw 311.
Adopt this structure; relative worm screw 311 eccentric settings of rocking handle 313 can increase the arm of force; the structure with respect to rocking handle 313 with the concentric setting of worm screw 311; use identical strength to shake rocking handle 313; eccentric structure can further increase the moment of output, makes operating personal more laborsaving when transferring and regain spare tyre.Certainly, rocking handle 313 also can with the concentric setting of worm screw 311.
On this basis, the lead angle of above-mentioned worm screw 311 can be set to be less than 3 °.Like this, make worm-and-wheel gear there is auto-lock function, make the position of tire to stop operating and be fixed on current location with rocking handle 313, further guarantee the working stability of above-mentioned draw off gear.
In the another kind of specific embodiment, as shown in Figure 8 and Figure 9, Fig. 8 is the structural representation that in Fig. 1, bracing frame 1 is connected by limiting component 12 with link span 2, the exploded drawings that Fig. 9 is Fig. 8; Above-mentioned draw off gear can also comprise and selectively limits the limiting component 12 that link span 2 horizontally rotates with respect to bracing frame 1.Adopt this structure, when standby tire is positioned on vehicle frame 200, by limiting component 12, can avoid link span 2 with respect to bracing frame 1 occurred level displacement, further guarantee working stability.
In concrete scheme, above-mentioned limiting component 12 is pull bar, and the two ends of pull bar removably connect by two bearing pins and bracing frame 1, link span 2 respectively.
Like this, when needs are spacing, pull bar is installed between bracing frame 1, link span 2, the fixing pull bar of length can limit the distance between bracing frame 1, link span 2, to avoid the two occurred level displacement, realizes simply, easily spacing effect.When spacing, pull bar is pulled down between bracing frame 1, link span 2, the two can be rotated by relative level.
In addition, the utility model also provides a kind of construction machinery and equipment, comprises vehicle frame 200 and is located at the spare tyre draw off gear on vehicle frame 200, and spare tyre draw off gear adopts the spare tyre draw off gear of construction machinery and equipment as above.
Because above-mentioned spare tyre draw off gear has as above technique effect, therefore, comprise that the construction machinery and equipment of this spare tyre draw off gear also should have identical technique effect, at this, no longer describe.
