Description
Technical Field
The utility model relates to a crew cut tower machine root festival technical field, especially a jib loading boom and balance arm integration root festival structure of crew cut tower machine.
Background
Tower cranes are generally classified into flat-top and pointed-end tower cranes. The pointed tower crane refers to a tower crane with the top of a truss connected with a cargo boom and a balance arm through a pull rod, the flat-head tower crane does not have the structure, and the top of the flat-head tower crane is the balance arm and the cargo boom. At present, a cargo boom root section and a balance arm root section of a flat-top tower crane are both independently fixed at the top of a truss, the cargo boom is connected to the cargo boom root section, the balance arm is connected to the balance arm root section, and the cargo boom root section and the balance arm root section are connected through a pin shaft in order to keep balance. The structure makes the root section of the cargo boom and the root section of the balance arm difficult to install, because when the tower crane is installed, one crane is usually found to complete the assembly of the structures such as the cargo boom, the balance arm and the like of the tower crane. When the structure is assembled, the truss is stressed seriously and unbalanced, and the service life of the truss can be greatly reduced. And under the condition that the center is seriously deviated, the truss is very unstable during installation, and the risk of safety accidents exists. Meanwhile, after the installation is finished, in the hoisting process of the tower crane, the closer the cargo boom is to one side of the truss, the larger the tensile force is, the cargo boom root section and the balance arm root section of the structure are connected through the pin shaft, so that the tensile force applied to the pin shaft is the largest, the requirements on the size of the pin shaft and the structure connected with the pin shaft are very high, and the maximum weight of the tower crane capable of hoisting is severely limited by the structure.

An object of the utility model is to overcome prior art's shortcoming, provide a balance arm and jib loading boom integration root festival structure convenient to installation and bearing capacity are strong.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a jib loading boom and balance arm integration root festival structure of crew cut tower machine, root festival structure is cuboid frame construction, including four bearing bars and a plurality of connecting rod, among the cuboid frame construction, four bearing bars are formed through connecting a plurality of connecting rods, two connecting rod middle parts that lie in the below in four bearing bars are provided with the fixing base, be provided with the pinhole on the fixing base, be provided with the connector that is used for being connected with the level xarm of jib loading boom on the bearing bar at root festival structure both ends respectively, be provided with the pinhole on the connector.
Specifically, one side of root festival structure is provided with the platform, be provided with the railing on the platform.
In particular, the platform is located on the section of the frame structure between the fixed base and the boom.
Specifically, be provided with the pulley on the position that is close to the fixing base in the cuboid frame construction, the pulley that is close to the fixing base is fixed in on the connecting rod of root festival structure bottom to one side that is close to the jib loading boom in the cuboid frame construction also is provided with the pulley, and the pulley that is close to jib loading boom one side articulates on a connecting rod at root festival structure top.
Specifically, the connecting rods comprise a cross rod perpendicular to the bearing rod and an inclined rod inclined to the bearing arm, and two ends of any one of the connecting rods are connected with the bearing rod.
The utility model has the advantages of it is following:
after the root festival integration of jib loading boom and balance arm, when installing root festival structure, can not cause the focus of truss to seriously skew to root festival structure and the hookup location of truss are located the middle part of root festival structure, and root festival structure is as integral structure when jack-up, and bearing capacity is stronger and the installation is more convenient, has improved the installation effectiveness.
