The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Referring to Fig. 1～Fig. 9, the various preferred embodiments of a kind of folding type leg disc mechanism of the utility model shown in it, folding type leg disc mechanism of the present utility model comprises the stay bearing plate 1 of captiveing joint with supporting leg 5, described stay bearing plate 1 is provided with the effect frame 2 that a plurality of and described stay bearing plate 1 is rotationally connected, preferably, each stay bearing plate 1 is symmetrical arranged with respect to described supporting leg 5; The bottom surface of described effect frame 2 under horizontality is lower than the horizontal surface of described stay bearing plate 1, between effect frame 2 of the present utility model and the stay bearing plate 1 for being rotationally connected, in effect frame 2 untapped states, the main body of effect frame 2 upwards is positioned at the position (such as Fig. 6 and shown in Figure 8) near supporting leg 5; And when the state of use, the main body of effect frame 2 rotates, and finally is horizontality (such as Fig. 7 and shown in Figure 9), jointly shares application force with stay bearing plate 1, and at this moment, the plane, bottom surface of effect frame 2 is lower than the bottom surface horizontal surface of stay bearing plate 1; Further, nonslipping spur 4 at the bottom of rubber-sole nonslipping spur 3 or the support pin is installed on the described effect frame 2, because the bottom surface of effect frame 2 under horizontality is lower than the horizontal surface of described stay bearing plate 1, add the effect of nonslipping spur 4 at the bottom of rubber-sole nonslipping spur 3 or the support pin, so that folding type leg disc mechanism of the present utility model has better support and anti-sideslip effect.
Preferably, effect frame 2 is rotationally connected by elastic axis and described stay bearing plate 1, and described elastic axis can be in elastic component and the rotating shaft part that remains close to supporting leg 5 positions in the untapped state at effect frame 2 for various in the prior art.
Further, referring to Fig. 3, comprise medial extremity (left side shown in Figure 3) and external side end (right side shown in Figure 3) on the described effect frame 2, have mounting groove 11 on the described stay bearing plate 1, as shown in Figure 2; Described effect frame 2 when horizontality, the medial extremity of described stay bearing plate 1 and described 11 spacing cooperations of mounting groove; In the utility model, be the inboard near a side of supporting leg 5, is the outside away from a side of supporting leg 5; Preferably, the medial extremity of effect frame 2 has ramp structure, and this ramp structure and described 11 spacing cooperations of mounting groove are when the main body of described effect frame 2 is positioned at the position of close supporting leg 5 (such as Fig. 6 and shown in Figure 8), effect frame 2 is recovered in the mounting groove 11, can reduce thus the space and use; When the main body of effect frame 2 is positioned at horizontality (such as Fig. 7 and shown in Figure 9), a side of mounting groove 11 (for example inboard) props up the ramp structure of described effect frame 2 medial extremitys, prevents from acting on frame 2 and is rotated further.
Preferably, the middle part of described effect frame 2 has the rotating hole 21 that matches with described elastic axis, as shown in Figure 3.
More preferably, the external side end of described effect frame 2 is provided with installs chute 22, as shown in Figure 3, nonslipping spur 4 at the bottom of rubber-sole nonslipping spur 3 or the support pin is installed on the described installation chute 22.Correspondingly, nonslipping spur 4 preferably has " worker " font cross section structure that matches with described installation chute 22 at the bottom of described rubber-sole nonslipping spur 3 or the support pin, as shown in Figure 4 and Figure 5.
Further referring to Fig. 4, described rubber-sole nonslipping spur 3 is comprised of rubber-sole nonslipping spur metal part 31 and downside rubber part 32; Referring to Fig. 5, nonslipping spur 4 is comprised of nonslipping spur metal part 41 at the bottom of the support pin and downside support pin part 42 at the bottom of the described support pin.
Principle of work of the present utility model and working process are:
Such as Fig. 1～shown in Figure 9, stay bearing plate 1 is welded to each other with vertical supporting leg 5; Effect frame 2 is hinged by elastic axis and stay bearing plate 1, and can do around elastic axis the rotation of certain angle, and elastic axis can make effect frame 2 keep relative static with stay bearing plate 1, and when horizontality, the lowest part of effect frame 2 is lower than stay bearing plate 1 bottom surface; Rubber-sole nonslipping spur 3 can optionally be installed on the effect frame 2 according to different use occasions from slide block of the anti-end of support pin 4, can certainly use simultaneously or the interval setting.11 have square groove on the described stay bearing plate 1, are welded with bracing frame 12, and bracing frame 12 is used for installing described elastic axis.
During use, the supporting leg dish is in the situation of not working, and effect frame 2 erects under the elastic force effect of elastic axis, and keeps certain angle.When the construction road surface is situation preferably during hard surfacing, rubber-sole nonslipping spur 3 is installed in the installation chute 22 of effect frame 2, the supporting leg dish is in state shown in Figure 6; When vertical leg 5 moved down, an end of effect frame 2 contacted with ground first, and under the application force between ground and the vertical leg 5, effect frame 2 begins to rotate; When stay bearing plate 1 bottom surface and ground distance 1cm(also can as required, during fabrication, be set as 2cm or other sizes with this distance) time, downside rubber part 32 and the ground of rubber-sole nonslipping spur 3 fit; When vertical leg 5 continues to move down, downside rubber part 32 produces deformation under the effect of pressure, when stay bearing plate 1 bottom surface contacts with ground, as shown in Figure 7, the compression of downside rubber part 32 reaches maxim, and at this moment the supporting leg dish has support and anti-effect of breakking away.
Another kind of situation when the construction road surface is the bad non-hard surfacing of situation, is installed on nonslipping spur at the bottom of the support pin 4 in the installation chute 22 of effect frame 2, and the supporting leg dish is in first state shown in Figure 8; When vertical leg 5 moved down, an end of effect frame 2 contacted with ground first, and effect frame 2 begins to rotate under the effect of ground and vertical leg 5; When stay bearing plate 1 bottom surface and ground distance 1cm, the downside support pin part 42 of nonslipping spur 4 contacts with the road surface at the bottom of the support pin; When vertical leg 5 continues to move down, downside support pin part 42 enters ground under the effect of pressure, when stay bearing plate 1 bottom surface contacts with ground, as shown in Figure 9, the inlet of downside support pin part 42 reaches maxim, and at this moment the supporting leg dish has and supports preferably and anti-sideslip effect.
Certainly, be understood that for those skilled in the art that the size of slide block of the anti-end of rubber-sole nonslipping spur 3 of the present utility model and support pin 4 can be carried out corresponding change as required to enlarge applicable situation.After wrecker construction finished, vertical leg 5 moved up behind the certain altitude, and effect frame 2 can return to initial condition under the effect of elastic axis, thereby reduces the lateral distance of supporting leg dish, is conducive to improve the passability that travels of wrecker.
And those skilled in the art also can according to different states of ground, select other Skidproof accessaries multi-form and size to replace rubber-sole nonslipping spur 3 and slide block of the anti-end of support pin 4 to use.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
