Abstract
A kind of syllogic arm crane, belongs to crane technical field, comprises rotating mechanism, turntable, jib lubbing mechanism, main hoisting mechanism, auxiliary hoisting mechanism, electric-control system and dynamical system, it is characterized in that this crane also comprises the boom system of a set of syllogic.The boom system of syllogic is made up of principal arm frame, principal arm tower head, secondary man-like shelf, secondary arm frame I, secondary arm frame II and drag-line.Principal arm frame lower end and turntable hinged, principal arm frame upper end is connected with principal arm tower head; Principal arm tower head there is the hinge of secondary arm frame I and bear the secondary man-like shelf of secondary arm frame I drag-line and secondary arm frame II drag-line pulling force; Secondary arm frame I lower end and principal arm tower head hinged; Secondary arm frame I upper end and secondary arm frame II lower end hinged; Secondary arm frame I is connected with the secondary man-like shelf on principal arm tower head with drag-line respectively with the head of secondary arm frame II.Effect of the present utility model and benefit are: jib be divide into three sections by this crane, and being convenient to increases lifting altitude, and manufacturing, transporting and installing all than being easier to.
Description
Technical field
The utility model belongs to technical field of crane equipment, relates to a kind of syllogic arm crane.
Background technology
The maximum lifting height of arm crane is determined by the length of jib.By the restriction of the conditions such as manufacture, transport and installation, the length of jib can not be done oversize.Only use one section of jib (principal arm frame) when lifting altitude is little, be called one-part form arm crane.When needing to increase lifting altitude, just on principal arm frame, increase by one section of secondary arm frame again, be called two-part arm crane.Two-part arm crane increases lifting altitude again, can only increase the length of principal arm frame and secondary arm frame, so the increase of lifting altitude is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of syllogic arm crane, to solve the problem.
The technical solution of the utility model is: this crane comprises rotating mechanism, turntable, jib lubbing mechanism, main hoisting mechanism, auxiliary hoisting mechanism, electric-control system and dynamical system, it is characterized in that this crane also comprises the boom system of a set of syllogic.The boom system of syllogic is made up of principal arm frame, principal arm tower head, secondary man-like shelf, secondary arm frame I, secondary arm frame II and drag-line.Principal arm frame lower end and turntable hinged, principal arm frame upper end is connected with principal arm tower head; Principal arm tower head there is the hinge of secondary arm frame I and bear the secondary man-like shelf of secondary arm frame I drag-line and secondary arm frame II drag-line pulling force; Secondary arm frame I lower end and principal arm tower head hinged; Secondary arm frame I upper end and secondary arm frame II lower end hinged; Secondary arm frame I is connected with the secondary man-like shelf on principal arm tower head with drag-line respectively with the head of secondary arm frame II.
Effect of the present utility model and benefit are: jib be divide into three sections by this crane, and being convenient to increases lifting altitude, and manufacturing, transporting and installing all than being easier to, and are particularly suitable for the fixing swinging arm crane of large-tonnage, big elevating height.

Detailed description of the invention
Below in conjunction with technical scheme and accompanying drawing, describe detailed description of the invention of the present utility model in detail.
As shown in Figure 1, wheel and the balance beam support of rotating operation mechanism turntable, and whole crane is rotated on the circular orbit on basis; Turntable is installed with drivers' cab, electric-control system, main hoisting mechanism, auxiliary hoisting mechanism, jib lubbing mechanism, counterweight beam, dynamical system, owner's cabinet frame and syllogic boom system; Jib lubbing mechanism, by the luffing pulley on variable-amplitude steel wire rope, turntable column and the luffing pulley on principal arm tower head, drives syllogic boom system to swing in vertical plane centered by hinge under principal arm frame, realizes luffing motion; Main hoisting mechanism, by the main lifting pulley on main hoist rope and principal arm tower head, drives main hoisting mechanism to make vertical displacement movement; Auxiliary hoisting mechanism, by the secondary lifting pulley on secondary hoist rope, secondary lifting pulley on principal arm tower head, secondary arm frame II top, drives the pair suspension hook that hoists to make vertical displacement movement; Dynamical system provides power supply for complete machine; Whole action of electric control system controls crane and miscellaneous function; Operating personnel implement the operation to complete machine in drivers' cab.
As shown in Figure 2, so-called syllogic boom system refers to that by these three sections of jibs of principal arm frame, secondary arm frame I and secondary arm frame II be the main boom system formed.Principal arm frame lower end is the hinge be connected with turntable, upper end is connected with principal arm tower head (principal arm frame tower head can regard a part for principal arm frame as), principal arm tower head is installed secondary man-like shelf and secondary arm frame I, secondary arm frame I and secondary arm frame II joins end to end, the head of secondary arm frame I is connected with the head of secondary man-like shelf by secondary arm frame I drag-line, and the head of secondary arm frame II is connected with the head of secondary man-like shelf by secondary arm frame II drag-line.During crane job, syllogic boom system integrally, under the traction of variable-amplitude steel wire rope, realizes luffing motion.
