Abstract
The utility model discloses a multisection telescopic arm support which is composed of a tower frame and a telescopic section; a plurality of sections of telescopic sections which are in sleeve connection with each other are sheathed and connected with the interior of the tower seat, a steel wire rope is tied at the lower end of the telescopic section at the top part, the steel wire rope passes round a top end pulley wheel, a lower end pulley wheel and a tower seat pulley wheel which are on each telescopic section at the middle part, and the steel wire rope is wound on a winding drum of a winding machine; the utility model has the advantages of big telescoping range, simple structure and convenient operation and benefits for transfer and transportation.
Description
The utility model belongs to jib-type crane tool technical field, relates in particular to the improvement of jib-type crane jib.
The jib-type crane tool mainly comprises hoisting crane (containing automobile crane, rubber tired crane, crawler crane) and tower crane voluntarily.The flexible power of the former its jib is hydrostatic drive, and its extension elongation and stretching speed all are subjected to the restriction of Hydraulic Elements, can't realize big stroke, fast speed; Adopt telscoping hydaulic cylinder in order to strengthen collapsing length, this structure not only structure is loaded down with trivial details, and seal complex has increased the seepage chance, very easily produces the downhill race of slip joint, and hydraulic actuating cylinder is in pressured state for a long time, is easy to flexural deformation.The latter's lifting pylon is the main body of hoisting crane, mostly adopt captive joint formula pylon, this version, trouble transportation inconvenience is installed, at present, has occurred the flexible tower structure of forming by inside and outside two sections pylons on the market, though this structure make integral transportation length reduced near half, but still existing the stroke deficiency, stretching speed is slow, operation is inconvenient, transportation lengths is still longer, can not adapt to the needs of civil construction.In sum, existing telescopic jib have all that stroke is little, the speed of stretching out is slow, the shortcoming of troublesome poeration, transportation inconvenience.
The purpose of this utility model is exactly that the hoisting crane multi-joint telescoping that a kind of transportation lengths is little, stroke is big, simple in structure jib will be provided.
In order to achieve the above object, the utility model comprises tower seat and slip joint, at least be socketed with the slip joint that two joints interlock each other on the tower seat, wire line hitch lies in the lower end of this multi-stage telescopic arms top of the trellis slip joint, and walk around top pulley and following head sheave on each slip joint at middle part successively, finally walk around tower seat pulley and be wound on the lifting drum.When the steel rope of lifting drum scrolling on it, the steady lifting of each slip joint.
After adopting this structure, owing to be socketed with multi-stage telescopic arms on the tower seat, transportation lengths shortens dramatically, and helps shifting and transportation; Just can make and stretch steadily that stroke is big owing to drive the steel rope that is wound on the lifting drum again so that respectively saving telescopic boom stretches simultaneously; And can determine arbitrarily as required to need not on-site installation by stroke, simple to operation.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a specific embodiment of the utility model hoisting crane multi-joint telescoping jib.
Be socketed with the slip joint (4) that can be positioned at middle part slip joint (2,3) and top on the fixing tower seat 1 shown in Figure 1 along two joints that tower seat 1 slides, steel rope 11 has two to detain respectively on two button mooring points 6 that lie in top slip joint 4 lower ends, and walk around the top pulley 5 that lays respectively on the middle part slip joint 3 that respectively saves the jib both sides, following head sheave 8 successively, walk around the top pulley 7 of middle part slip joint 2, following head sheave 10 again, walk around the tower seat pulley 9 on the tower seat 1 at last and be wound in simultaneously on the same cylinder side of lifting drum 12.When lifting drum 12 rotates counterclockwise, tighten up two steel ropes 11 of both sides simultaneously, make the slip joint 2,3 and the top slip joint 4 at middle part stretch out synchronously equably, above-mentioned symmetric arrangement makes each slip joint stressed evenly, motion is steadily; When lifting drum 12 clockwise rotated, two steel ropes 11 loosened simultaneously, and each saves slip joint and regains synchronously, and retraction tower seat 1 inside makes transportation lengths shorten dramatically, and were convenient to shift transportation.
The top pulley and the following head sheave of each joint middle part slip joint are movable pulley, 9 on tower seat pulley is a fixed pulley, top pulley 5,7 on the slip joint 2,3 of middle part all is installed on corresponding slip joint top to next fragment position, to control the maximum overhang of every joint slip joint, when making telescopic boom reach maximum overhang and not slippage guarantees its safety and stability.It is the box type construction of rectangle that tower seat 1 and slip joint adopt cross sectional shape, so both can obtain higher structural stability and bulk strength, can alleviate deadweight again, rationally uses material.Certainly, tower seat and jib also can adopt other corresponding construction pattern.
Claims (4)
1, a kind of hoisting crane multi-joint telescoping jib, comprise tower seat (1), it is characterized in that: be socketed with the slip joint (2,3,4) that two joints interlock each other on the tower seat (1) at least, steel rope (11) button lies in the lower end of the slip joint (4) at top, and the top pulley (5,7) on each slip joint (2,3) in the middle part of walking around successively, following head sheave (8,10) and tower seat pulley (9), and be wound on the lifting drum (12).
2, multi-joint telescoping jib according to claim 1, it is characterized in that: its top pulley of the slip joint at described middle part (2,3) (5,7), down head sheave (8,10) and tower seat pulley (9) be for being arranged in the jib both sides symmetrically, and every side all is installed with steel rope (11).
3, multi-joint telescoping jib according to claim 1 is characterized in that, top pulley (5,7) and tower seat pulley (9) lay respectively at corresponding slip joint (2,3) and tower seat (1) top to upper/lower positions.
4, multi-joint telescoping frame according to claim 1 is characterized in that: it is the box type construction of rectangle that telescopic boom (2,3,4) and tower seat (1) all adopt the cross section.
