Embodiment
It should be noted that in the case where not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Mutually combination.It is described in detail below in conjunction with 1 to 7 pair of specific embodiment of the invention of accompanying drawing.
As shown in Figures 1 to 3, the counterweight mounting system that the specific embodiment of the invention is proposed specifically includes jacking cylinder 4, counterweight
3rd, pull bar 6 and hitch bar 5, wherein, two jacking cylinders 4 are arranged vertically, and its bottom is fixed on the vehicle frame 1 of crane, are hung
The top of extension bar 5 is connected with counterweight support 2；As shown in figure 4, counterweight 3 is made up of three 3 pieces of counterweights, and it is provided with counterweight 3 perpendicular
Nogata is to the through hole 31 of extension, and the bottom surface of counterweight 3 is provided with the counterbore 32 of two fovea superiors, and (counterbore 32 and jacking cylinder 4 are one-to-one
Matching)；As shown in FIG. 5 and 6, pull bar 6 specifically includes sleeve pipe 61, base 63 and hangoff receptacle 62, and base 63 is fixedly installed on sleeve pipe
61 bottom, hangoff receptacle 62 is fixedly installed on the top of sleeve pipe 61, and pull bar 6 passes through spiral shell through the through hole 31 in counterweight 3, base 63
Bolt and the bottom surface of counterweight 3 are fixed, and hangoff receptacle 62 is used to be connected with hitch bar 5.
Generally, on crane, counterweight support 2 is connected with the turntable of crane；During work, counterweight support 2 follows turntable
Rotate.When mounting counterweight 3, turntable is first rotated into counterweight assembly side certain angle partially, then counterweight 3 is disposed
On jacking cylinder 4, the top of jacking cylinder 4 is inserted in the counterbore 32 of counterweight 3 bottom surface, then driven and match somebody with somebody by jacking cylinder 4
3 risings are weighed until preset height, now the top surface of counterweight 3 is closer to counterweight support 2, last revolving-turret is by hitch bar 5
It is connected with hangoff receptacle 62.
As it can be seen in figures 5 and 6, being provided with two slotted eyes 64 on hangoff receptacle 62, two slotted eyes 64 are arranged symmetrically in sleeve pipe 61
Both sides；Accordingly, as shown in fig. 7, the bottom of hitch bar 5 is provided with inverted T-shaped hook, inverted T-shaped hook coordinates with slotted eye 64.It will hang
When extension bar 5 is connected with hangoff receptacle 62, the inverted T-shaped hook of hitch bar 5 is first placed in the height matched with slotted eye 64, then driven
Hitch bar 5 is moved toward the direction of slotted eye 64, until in inverted T-shaped hook insertion slotted eye 64.In order to prevent in the course of work, hitch bar 5
Depart from slotted eye 64, step (counterbore 32 of similar fovea superior) is provided with slotted eye 64, behind inverted T-shaped hook insertion slotted eye 64, hang
Extension bar 5 is up moved slightly, and the outward flange for linking up with inverted T-shaped is caught in the range of step restriction；Under the position-limiting action of step,
Horizontal level between hitch bar 5 and hangoff receptacle 62 is limited to.
In example is further carried out, two through holes 31 are provided with force-bearing situation, counterweight 3 in order to improve, accordingly, are drawn
The quantity of bar 6 is also two, pull bar 6 with through hole 31 is one-to-one matches；Correspondingly, the quantity of slotted eye 64 and hitch bar 5 is four
It is individual, slotted eye 64 with hitch bar 5 is also one-to-one matches.
In addition, in order to prevent the problem of counterweight 3 is tilted, as shown in fig. 7, being provided with counterweight support 2 horizontally disposed
Pin-and-hole and the mounting hole arranged vertically, the processing of pin-and-hole is on the basis of the pivoting support mounting surface of turntable, it is ensured that levelness；Peace
When filling hitch bar 5, in the first insertion of hitch bar 5 mounting hole, then by the pin-and-hole on the pin-and-hole on the top of hitch bar 5 and counterweight support 2
Alignment, finally inserts horizontal bearing pin 7 in pin-and-hole.
Compared with prior art, above-mentioned counterweight mounting system has advantages below：
1) disassembly process of counterweight 3 is simpler, and semi-automation can be achieved；
2) simple in construction, reliability is high, and cost is low；
3) counterweight 3 is lifted by jacking cylinder 4, and rodless cavity oil-feed, oil cylinder cylinder diameter can reduce；
4) balance weight hanging is safe and reliable without mechanical locking using mechanical；
5) hitch bar 5 is positioned using horizontal bearing pin 7, it is to avoid the highly inconsistent situation of counterweight 3 or so occur.
In addition, the specific embodiment of the invention also proposes a kind of crane；The crane includes above-mentioned counterweight mounting system.
Finally, the specific embodiment of the invention also proposes a kind of counterweight hooking method, specifically includes following steps：
S0：Turntable is rotated to precalculated position, i.e., turntable is rotated into counterweight side certain angle partially；
S1：Counterweight 3 is placed on jacking cylinder 4, and in the top insertion counterbore 32 of jacking cylinder 4；
S2：Jacking cylinder 4 extends and drives counterweight 3 to move up, until reaching predetermined altitude so that the bottom of hitch bar 5
The height with hangoff receptacle 62 is held to match；
S3：The predetermined angular of rotating weight support 2, makes hangoff receptacle 62 be articulated on the bottom of hitch bar 5.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
