Abstract

The utility model relates to a synchronous telescoping mechanism for the crane that is arranged along the radial direction, comprising a basal arm, a first telescoping arm, a second telescoping arm a telescoping oil cylinder and a reverse drawing steel wire. The cylinder body of the telescoping oil cylinder is positioned on the first telescoping arm with the piston rod positioned on the root of the basal arm. The root of the first telescoping arm is provided with a first fixed pulley, and one end of the reverse drawing steel wire is connected with the root of the second telescoping arm, while the other end is fixedly positioned on the head of the basal arm by crossing the first fixed pulley. The head of the first telescoping arm is provided with a third fixed pulley. One side of the outer circle of the third fixed pulley on the head of the first telescoping is provided with one or more than one fourth fixed pulley in a radiated manner. The tail of the second telescoping arm is provided with the second fixed pulley. One end of the extending steel wire is positioned on the root of the basal arm, while the other end is across the third fixed pulley. The second fixed pulley and the fourth fixed pulley are arranged on the root of the basal arm. The utility model relates to a synchronous telescoping mechanism in radial disposal for the crane, and the utility model has the advantages of simple and compact structure, convenient stallation and reliable performance.

Description

Hoisting crane radial arrangement synchronization telescope mechanism
Technical field
The utility model is mainly concerned with the hoisting crane field, refers in particular to a kind of hoisting crane radial arrangement synchronization telescope mechanism.
Background technology
Telescoping mechanism is the critical component of car hosit, and the carrying the when hoisting arm expansion of hoisting crane and arm lift heavy all realizes by telescoping mechanism.The quality of telescoping mechanism has extremely important effect to the lifting performance of car load to a certain extent.In the prior art, the home and abroad all adopts oil cylinder to add the telescoping mechanism of steel rope at present, and stretch mode adds synchronously for order, and flexible steel rope is arranged in two backlashs between the arm.But, increasing along with the hoisting crane tonnage, the diameter that is arranged in the flexible steel rope between the arm is also more and more thicker, traditional flexible steel rope is horizontal arrangement, caused the distance of side direction between arm excessive, when often being designed into the telescopic boom of cross section minimum, the rigidity of side direction is big inadequately, can't realize the equal strength design of arm, thereby have influence on the further raising of lifting weight.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the hoisting crane that the utility model provides a kind of simple and compact for structure, easy for installation, dependable performance is with radial arrangement synchronization telescope mechanism.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of hoisting crane radial arrangement synchronization telescope mechanism, it comprises basic arm, first telescopic boom, second telescopic boom, the telescopic oil cylinder and the steel rope of pulling back, it is characterized in that: the cylinder body of described telescopic oil cylinder is fixed on first telescopic boom, its piston rod is fixedly arranged on basic arm roots, the described first telescopic boom root is provided with first fixed pulley, the end of steel rope of pulling back is connected in the root of second telescopic boom, the other end is walked around the head that first fixed pulley is installed in basic arm, the head of described first telescopic boom is provided with the 3rd fixed pulley, the 3rd fixed pulley outer ring one side is provided with one or more the 4th fixed pulley radially on the head of described first telescopic boom, the afterbody of described second telescopic boom is provided with second fixed pulley, stretch out steel rope one end and be fixed in basic arm roots, the other end is walked around the 3rd fixed pulley, second fixed pulley and the 4th fixed pulley are fixed in the root of basic arm.
The described steel rope that stretches out is radial arrangement on the 3rd fixed pulley and the 4th fixed pulley.
Compared with prior art, advantage of the present utility model just is: the utility model hoisting crane is easy to maintenance with the simple compactness of radial arrangement synchronization telescope mechanism structure, assembling, can improve the complete machine performance of hoisting crane, the reliability of assurance work, mechanism of the present utility model is installed in the side between the arm, with the conventional mounting form relatively, the horizontal space between shared arm want half as large about, help the layout in arm cross section.
