The problems that the crane with a crane lifting arm is required to be equipped with a lifting winch, the structure is complex and the overturning stability of the crane is low in the prior art are solved. The crane with the connecting rod telescopic lifting arm comprises a lifting arm, an amplitude-change cylinder, a turntable and a chassis, wherein the lifting arm consists of a connecting rod mechanism, a telescopic cylinder, an amplitude-change bracket, a lifting steel wire rope and a lifting hook; two rod heads at the left end of the connecting rod mechanism are connected with the lifting steel wire rope; two rod heads at the right end of the connecting rod mechanism are hinged with the amplitude-change bracket through a pin shaft; the hinged joint of two rods at the right end of the connecting rod mechanism is hinged with the telescopic cylinder which is fixed on the amplitude-change bracket; the amplitude-change bracket is connected with the turntable of the crane through the amplitude-change cylinder; and the turntable is connected with the chassis through a slewing bearing. When the crane with the connecting rod telescopic lifting arm is used for an automobile crane, the chassis with fewer axles can be used, and when the crane with the connecting rod telescopic lifting arm is used for a crawler crane, light weight crawler discharging can be realized.
Description
Technical field
The utility model relates to elevator machinery, and particularly a kind of arm is the hoisting crane of shrinking connecting-rod.
Background technology
The crane arm of prior art has two kinds: a kind of is that single cylinder adds rope row telehoist arm (like Fig. 1), promotes two joint arms, 5 realization fore and aft motion through the telescopic oil cylinder 3 that is fixed on the basic arm 4.Be separately fixed at two, three joint arm top sheaves 2 simultaneously and promote three joint arms, 1 realization fore and aft motion.Another kind is a heavy wool cylinder telehoist arm (like Fig. 2), saves arms 1 realization fore and aft motion through telescopic oil cylinder 3 and 6 promotions, the two joint arms 5, three that are fixed on basic arm 4 and the two joint arms 5 respectively.
The crane arm of prior art, the driver train of fore and aft motion is complicated, installs, safeguards relatively difficulty, and telescopic oil cylinder influences the lifting performance of hoisting crane from great.
Use the hoisting crane of the crane arm of prior art, structure is as shown in Figure 5.Arm 7 is connected with turntable 9 through amplitude oil cylinder 8, and turntable 9 is installed on the hoisting crane chassis 10.The hoisting crane of prior art need be equipped with the winding plant 11 that hoists, simultaneously, because of its arm 7 from great, influence the overturning stability of hoisting crane.
Summary of the invention
The purpose of the utility model is the deficiency that exists to prior art; A kind of hoisting crane with connecting rod telescopic hoist boom is provided, solves the hoisting crane of the crane arm that uses prior art, need to be equipped with the winding plant that hoists; Complex structure, and the problem of hoisting crane overturning stability difference.
The utility model is realized through following technical scheme.
A kind of hoisting crane with connecting rod telescopic hoist boom; Comprise: arm, amplitude oil cylinder, turntable, chassis; It is characterized in that: said arm is made up of connecting rod mechanism, telescopic oil cylinder, luffing support, hoisting wirerope and suspension hook; Two bar heads of said connecting rod mechanism left end are connected with said hoisting wirerope, and two bar heads of said connecting rod mechanism right-hand member are hinged through bearing pin and said luffing support, and the hinged place of two bars of said connecting rod mechanism right-hand member is hinged with the said telescopic oil cylinder that is fixed on the said luffing support; Said luffing support is connected with rotating platform of crane through said amplitude oil cylinder, and said turntable is connected with said chassis through pivoting support.
The utility model compared with prior art has the following advantages and beneficial effect:
1, the arm main body adopts connecting rod mechanism.Simple in structure, in light weight, cost of manufacture is low, use, easy to maintenance.
2, the winding plant that need not hoist.Remove the winding plant that hoists, can select more low power driving engine for use, make the turntable layout compacter, reduce product weight, practice thrift cost.
3, the flexible and luffing of band rated load.Operation is simpler, quick during hoisting heavy.
4, use the bar telescopic hoist boom can effectively alleviate the hoisting crane deadweight, when being used for car hosit, can adopt the few chassis of the number of axle; When being used for crawler crane, but the lightweight crawler belt is got off.

The utility model is further described through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 4,5,6, shown in 7; A kind of car hosit with connecting rod telescopic hoist boom; Comprise: arm 7, amplitude oil cylinder 8, turntable 9, chassis 10; Said arm 7 is made up of connecting rod mechanism 7-1, telescopic oil cylinder 7-2, luffing support 7-3, hoisting wirerope 7-4 and suspension hook 7-5; Two bar heads of said connecting rod mechanism 7-1 left end are connected with said hoisting wirerope 7-4, and two bar heads of said connecting rod mechanism 7-1 right-hand member are hinged through bearing pin and said luffing support 7-3, and the hinged place of two bars of said connecting rod mechanism 7-1 right-hand member is hinged with the said telescopic oil cylinder 7-2 that is fixed on the said luffing support 7-3; Said luffing support 7-3 is connected with rotating platform of crane 9 through said amplitude oil cylinder 8, and said turntable 9 is connected with said chassis 10 (getting off) through pivoting support.Relatively rotating through the swing type mechanism that is arranged between them of getting on or off the bus realizes.When using rubber-tyred chassis (car chassis or All-terrain chassis), the car load configuration is as shown in Figure 7.Chassis 10 is 4, but is not limited to 4.
Like Fig. 4,5,6, shown in 8; A kind of crawler crane with connecting rod telescopic hoist boom; Comprise: arm 7, amplitude oil cylinder 8, turntable 9, chassis 10; Said arm 7 is made up of connecting rod mechanism 7-1, telescopic oil cylinder 7-2, luffing support 7-3, hoisting wirerope 7-4 and suspension hook 7-5; Two bar heads of said connecting rod mechanism 7-1 left end are connected with said hoisting wirerope 7-4, and two bar heads of said connecting rod mechanism 7-1 right-hand member are hinged through bearing pin and said luffing support 7-3, and the hinged place of two bars of said connecting rod mechanism 7-1 right-hand member is hinged with the said telescopic oil cylinder 7-2 that is fixed on the said luffing support 7-3; Said luffing support 7-3 is connected with rotating platform of crane 9 through said amplitude oil cylinder 8, and said turntable 9 is connected with said crawler body 10 through pivoting support.The car load configuration is as shown in Figure 8.
The utility model method of work:
Initial connecting rod mechanism 7-1 is folding (like Fig. 4) entirely, and this moment, telescopic oil cylinder 7-2 was full reduced.After flexible plan was confirmed, telescopic oil cylinder 7-2 stretched out by predetermined intention, middle the bearing pin (hinged places of two bars) that its cylinder bar promotes connecting rod mechanism 7-1 travel forward (at this moment, can confirm that according to the principle of connecting rod mechanism whole arm is extending).After reaching expectation length, telescopic oil cylinder 7-2 motion stops, and telescoping boom stops to stretch out.The arm withdrawal is moved and is stretched out action on the contrary.The luffing motion of arm is realized with luffing support 7-3 by amplitude oil cylinder 8 jointly.When amplitude oil cylinder 8 when state shown in Figure 5 stretches out, luffing support 7-3 clockwise rotates around turntable 9 pivotal points.Because fixing through bearing pin between connecting rod mechanism 7-1 and the luffing support 7-3, the connecting rod telescopic boom is just along with the luffing support clockwise rotates.The rotation of getting on the bus then drives through the miniature gears that rotary reducer is with of captiveing joint with turntable.Realize 360 ° of unrestricted rotations.
