The beneficial effects of the utility model are
This structure is in the time of hoisting crane work, and support is connected with supporting seat by hubbing structure and latch-up structure makes stent support prevent the hypsokinesis oil cylinder; And in when transportation, the structure that unlocks, support rotate and makes support to fold around hubbing structure, thereby, prevent that the hypsokinesis oil cylinder is placed to, avoid transporting superelevation.
Description of drawings
Fig. 1 is the structural representation that the anti-hypsokinesis oil cylinder supporting construction of the utility model is in the state of propping;
Fig. 2 is the structural representation that the anti-hypsokinesis oil cylinder supporting construction of the utility model is in flat condition;
Fig. 3 is the enlarged diagram of A portion among Fig. 1.
The specific embodiment
Further specify architectural feature of the present utility model below in conjunction with accompanying drawing.
See also Fig. 1, Fig. 2 and Fig. 3, Fig. 1, Fig. 2 and Figure 3 shows that the utility model is arranged on the embodiment that is used to support the anti-hypsokinesis oil cylinder 2 that has surpassed on the principal arm 1, comprises supporting seat 3 and support 4.
Supporting seat 3 is fixed on the principal arm 1.Described supporting seat 3 comprises transverse slat 31 and is positioned at 31 liang of side connecting plates 32 of transverse slat and stay bearing plate 33, described connecting panel 32 is two and surrounds U-shaped with transverse slat 31, described stay bearing plate 33 is two and surrounds U-shaped with transverse slat 31 that the U-shaped that described stay bearing plate 33 and transverse slat 31 surround is stuck on the principal arm 1.
Described hubbing structure 43 comprises first bearing pin 431, be opened in the hinge hole of described connecting portion 41 and be opened in the connecting bore of described supporting seat 3.
Described latch-up structure 44 comprises second bearing pin 441, be opened in the through hole of connecting portion 41 and be opened in the interlocking hole of supporting seat 3; Described connecting portion 41 by first bearing pin 431 pass the hinge hole with connecting bore, pass through hole by second bearing pin 441 and be connected with supporting seat 3 with the interlocking hole, the external side end of first bearing pin 431 and second bearing pin 441 is connected safety pin pin 432.
Described supporting construction comprises that also second bearing, 5, the second bearings 5 are fixed in described principal arm 1 and are connected with the nylon block 6 of U-shaped.
See also Fig. 1, Fig. 2 and in conjunction with Fig. 3, principle of work of the present utility model is as follows:
1, in the time of hoisting crane work
Second bearing pin 441 that first bearing pin 431 of hubbing structure 43 passes the connecting bore of the hinge hole of connecting portion 41 and supporting seat 3 and latch-up structure 44 passes the interlocking hole of the through hole 41 and the supporting seat 3 of connecting portion, make support 4 be in the state of propping, then, surpass anti-hypsokinesis oil cylinder 2 and be positioned at support portion 42, at 4 time-outs of support, support 4 is 130 degree angles with jib 1 upper side, initialization height when the oil cylinder height that this moment, support was propped is its work.
2, when transportation
Extract second bearing pin 441 of latch-up structure 44, because first bearing pin 431 of hubbing structure 43 still passes the connecting bore of hinge hole and supporting seat 3, therefore, hubbing structure 43 is connected support 4 with supporting seat 3, and support 4 rotates with respect to supporting seat 3 around first bearing pin 431.Thereby support 4 does not support and has surpassed anti-hypsokinesis oil cylinder 2, then, has surpassed anti-hypsokinesis oil cylinder 2 and has set level, surpassed on the U-shaped nylon block 6 that anti-hypsokinesis oil cylinder 2 is positioned at second supporting seat 5, thereby, in the time of transportation, surpassed anti-hypsokinesis oil cylinder 2 and be placed to, reduced shipping height.In addition, because an end that has surpassed anti-hypsokinesis oil cylinder 2 is connected on the principal arm 1, therefore, when an other end that has surpassed anti-hypsokinesis oil cylinder 2 was positioned at U-shaped nylon block 6, the motion that has surpassed anti-hypsokinesis oil cylinder 2 can also be limited in the two side 61 of the nylon block 6 of U-shaped.
