Abstract
The invention relates to a connecting rod-telescopic crane boom, relates to lifting machinery, and solves the problems that the traditional crane boom has a complicated drive mechanism and is difficult to install and maintain. The connecting rod-telescopic crane boom provided by the invention comprises a connecting rod mechanism, a lifting steel wire rope, a telescopic oil cylinder, a derricking oil cylinder and a derricking support, wherein one end of the connecting rod mechanism is connected with the lifting steel wire rope, and the other end of the connecting rod mechanism is hinged with the derricking support through a pin shaft; and the other end of the connecting rod mechanism is also hinged with the telescopic oil cylinder fixedly arranged on the derricking support, and the derricking support is connected with a crane rotating platform through the derricking oil cylinder. The connecting rod-telescopic crane boom is used for automobile cranes or crawler cranes, and has the advantages of simple structure, light weight, low cost of production, convenience in use and maintenance and the like.
Description
Technical field
The present invention relates to elevator machinery, particularly a kind of arm of hoisting crane.
Background technology
The crane arm of prior art, generally two kinds commonly used: a kind of is that single cylinder adds rope row telehoist arm (like Fig. 1), realizes fore and aft motion through the telescopic oil cylinder 03 promotion two joint arms 05 that are fixed on the basic arm 04.Be separately fixed at two, three joint arm top sheaves 02 simultaneously and promote three joint arms, 01 realization fore and aft motion.Another kind is a heavy wool cylinder telehoist arm (like Fig. 2), saves arms 01 realization fore and aft motion through telescopic oil cylinder 03 and 06 promotion, the two joint arms 05, three that are fixed on basic arm 04 and the two joint arms 05 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.Be illustrated as three joint arm arms, if the arm joint number is many more, its shortcoming is obvious more, even can't adopt above-mentioned two kinds of stretch modes.
Summary of the invention
The object of the invention is exactly the deficiency that exists to prior art, and a kind of connecting rod telehoist arm is provided, and it is complicated to solve existing crane arm driver train, installs, problem difficult in maintenance.
The present invention realizes through following technical scheme.
A kind of connecting rod telehoist arm; It is characterized in that: said arm comprises: connecting rod mechanism, hoisting wirerope, telescopic oil cylinder, amplitude oil cylinder, luffing support; Said connecting rod mechanism one end is connected with said hoisting wirerope; The said connecting rod mechanism other end is hinged through bearing pin and said luffing support, and the said connecting rod mechanism other end is also hinged with the said telescopic oil cylinder that is fixed on the said luffing support, and said luffing support is connected with rotating platform of crane through said amplitude oil cylinder.
Said hoisting wirerope is through the pulley connecting shackle.
The present invention compared with prior art has the following advantages and beneficial effect:
Because the arm main body adopts connecting rod mechanism, makes crane arm simple in structure, in light weight, cost of manufacture is low, use, easy to maintenance.Because turntable is realized the luffing motion of arm through amplitude oil cylinder and luffing support, so operation is simpler during hoisting heavy, fast.

Fig. 2 is the structural representation of the heavy wool cylinder telehoist arm of prior art;
Fig. 3 is a kind of structural representation (folded state) of connecting rod telehoist arm;
Fig. 4 is a kind of structural representation (mode of operation) of connecting rod telehoist arm;
Fig. 5 is the birds-eye view of Fig. 4.
The present invention is further described through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 3,4, shown in 5; A kind of connecting rod telehoist arm; Comprise: connecting rod mechanism 3, hoisting wirerope 1, telescopic oil cylinder 4, amplitude oil cylinder 2, luffing support 6; Said connecting rod mechanism 3 one ends are connected with said hoisting wirerope 1; Said connecting rod mechanism 3 other ends are hinged through bearing pin and said luffing support 6, and said connecting rod mechanism 3 other ends are also hinged with the said telescopic oil cylinder 4 that is fixed on the said luffing support 6, and said luffing support 6 is connected with rotating platform of crane 7 through said amplitude oil cylinder 2.
Said hoisting wirerope 1 is through pulley connecting shackle 5.
Method of work of the present invention:
Initial connecting rod mechanism 3 is folding (like Fig. 3) entirely, and this moment, telescopic oil cylinder 4 was full reduced.After flexible plan was definite, telescopic oil cylinder 4 stretched out by predetermined intention, and its cylinder bar promotes the axially preceding motion of intermediate pin (at this moment, can confirm that according to the principle of connecting rod mechanism whole arm is in elongation) of connecting rod mechanism 3.After reaching expectation length, telescopic oil cylinder 4 motions stop, 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 by amplitude oil cylinder 2 and luffing support 6 jointly.When amplitude oil cylinder 2 when state shown in Figure 3 stretches out, luffing support 6 clockwise rotates around the turntable pivotal point.Because fixing through bearing pin between connecting rod mechanism 3 and the luffing support 6, the connecting rod telescopic boom is just along with the luffing support clockwise rotates.
Claims (2)
1. connecting rod telehoist arm; It is characterized in that: said arm comprises: connecting rod mechanism (3), hoisting wirerope (1), telescopic oil cylinder (4), amplitude oil cylinder (2), luffing support (6); Said connecting rod mechanism (3) one ends are connected with said hoisting wirerope (1); Said connecting rod mechanism (3) other end is hinged through bearing pin and said luffing support (6); Said connecting rod mechanism (3) other end is also hinged with the said telescopic oil cylinder (4) that is fixed on the said luffing support (6), and said luffing support (6) is connected with rotating platform of crane (7) through said amplitude oil cylinder (2).
