Description
Technical Field
The invention relates to a balance arm connecting device of a small tower crane, in particular to a connecting device of an inclined rear pull rod of a small tower crane, belonging to the technical field of crane manufacturing.
Background
Tower crane tower is called tower crane for short, and its boom is mounted on the rotating crane of high tower body. The working space is large, and the device is mainly used for vertical and horizontal conveying of materials and installation of building components in building construction. The device consists of a metal structure, a working mechanism and an electrical system. The metal structure comprises a tower body, a crane boom, a base and the like. The working mechanism has four parts of lifting, amplitude variation, rotation and walking. The electric system comprises a motor, a controller, a power distribution cabinet, a connecting circuit, a signal and lighting device and the like.
The common small tower crane is directly connected with the balance arm through the hinged support, the inclined rear pull rod and the balance arm do not rotate, and if the inclined rear pull rod and the balance arm rotate, lateral inclined abrasion can be generated. The inclined rear pull rod can not be folded and laid on the balance arm during transportation. In recent years, in small-sized building construction such as three-storey buildings, residential buildings, low-storey industrial buildings and the like, a general building tower crane is mostly adopted, so that the construction site is inconvenient to install, transport and convert, the construction cost is high, and the operation efficiency is low. Especially, when new rural construction facilities are built, repeated disassembly and assembly is often needed, but the common tower crane becomes a plurality of components after disassembly, other transportation equipment is needed to be used for transition in the transportation process, and the transportation cost is increased under the condition that a plurality of components cannot be folded and placed.
Disclosure of Invention
The invention aims to provide a connecting device of a rear inclined pull rod of a small tower crane, which can ensure that the rear inclined pull rod and a balance arm do not have lateral abrasion when rotating through a hinge point.
The technical scheme is as follows: the utility model provides a small-size tower crane machinery back pull rod connecting device that inclines, includes tower cap, balance arm and back pull rod to one side, and balance arm tip articulates in tower cap bottom, and the back pull rod that inclines is connected with the balance arm other end and tower cap top respectively, it is articulated through rotatable formula coupling assembling between balance arm and the back pull rod to one side. The connecting assembly can ensure that each connecting hinge point bears unidirectional tension in a respective rotatable plane. In the installation and dismantlement processes, articulated department can smoothly rotate, and in the transportation process, can realize keeping flat on the balance arm after oblique back pull rod is folding.
The priority, coupling assembling is "worker" font structure, including the connecting plate of middle transition tie-beam and both sides, transition tie-beam respectively with the connecting plate fixed connection of both sides, the connecting plate both ends are equipped with pull rod hinge hole and balance arm hinge hole respectively, coupling assembling is articulated through balance arm hinge hole and balance arm, and is articulated through pull rod hinge hole and oblique back pull rod. The balance arm is connected with the inclined rear pull rod through the pull rod hinge hole and the balance arm hinge hole in the connecting plate, and meanwhile, the rotation of the connecting part can be smooth and easy.
In order to further improve the reliability of the invention, a reinforcing plate is arranged at the joint of the transitional connecting beam and the connecting plates at the two sides.
Has the advantages that: the invention provides a flexible and reliable connecting device for self-mounting and dismounting the balance arm of the small-sized tower crane, so that the original fixed connecting hinge point becomes a rotatable connecting hinge point, the balance arm and the mechanism and the structural component on the balance arm are smoothly lifted or rotated by the inclined rear pull rod, and the mounting and dismounting workload of the mounting, dismounting and transporting working conditions is reduced to the utmost extent; and the conversion of the working conditions of installation, disassembly and transportation becomes quicker.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of the junction of the present invention.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1, the connecting device for the oblique rear pull rod of the small-sized tower crane comprises a tower cap 1, a balance arm 2 and an oblique rear pull rod 3, wherein the end part of the balance arm 2 is hinged to the bottom of the tower cap 1, the oblique rear pull rod 3 is respectively connected with the other end of the balance arm 2 and the top of the tower cap 1, and the balance arm 2 is hinged to the oblique rear pull rod 3 through a rotatable connecting assembly 4. By means of the connecting assembly 4 it is ensured that each connecting hinge point is subjected to a unidirectional tensile force in the respective plane of rotation. In the installation and dismantlement processes, articulated department can smoothly rotate, in the transportation, can realize keeping flat on balance arm 2 after oblique back pull rod 3 is folding.
As shown in fig. 2, the connection assembly 4 is of an "i" shaped structure, and includes a middle transitional connection beam 41 and two side connection plates 42, the transitional connection beam 41 is respectively and fixedly connected with the two side connection plates 42, two ends of the connection plates 42 are respectively provided with a pull rod hinge hole 43 and a balance arm hinge hole 44, the connection assembly 4 is hinged to the balance arm 2 through the balance arm hinge hole 44, and is hinged to the inclined rear pull rod 3 through the pull rod hinge hole 43. The balance arm 2 is connected with the inclined rear pull rod 3 through the pull rod hinge hole 43 and the balance arm hinge hole 44 on the connecting plate 42, and meanwhile, smooth rotation of the connecting position is guaranteed.
In order to further improve the reliability of the present invention, a reinforcing plate 45 is disposed at the connection position of the transitional connecting beam 41 and the two side connecting plates 42.
The invention provides a flexible and reliable connecting device for self-mounting and dismounting the balance arm 2 of the small-sized tower crane, so that the original fixed connecting hinge point becomes a rotatable connecting hinge point, the balance arm 2 and the mechanism and the structural component on the balance arm are smoothly pulled up or rotationally put down through the inclined rear pull rod 3, and the mounting and dismounting workload of the mounting, dismounting and transporting working conditions is reduced to the utmost extent; and the conversion of the working conditions of installation, disassembly and transportation becomes quicker.
