Abstract
A connection apparatus for a rear-oblique pull rod of a miniature tower-type hoisting machinery comprises a tower cap, a balance arm and a rear-oblique pull rod; the end part of the balance arm is hinged to the bottom of the tower cap; the rear-oblique pull rod is connected with the other end of the balance arm and the top of the tower cap; and the balance arm and the rear-oblique pull rod are in hinged connection via a rotatable connection assembly. The beneficial effects comprise that a flexible reliable connection apparatus is provided for self mounting, dismounting of the balance arm of the miniature tower-type hoisting machinery, and an original fixed connection hinging point is changed into a rotatable connection hinging point, so that the balance arm, and mechanism and structural parts above the balance arm can be successfully pulled up or vertically put down through the rear-oblique pull rod, and workload of mounting and dismounting of the hoisting machinery or under transportation operating conditions is furthest reduced, and mounting, dismounting and conversion of transportation operating conditions are relatively rapid.
Description
Technical field
This invention relates to a kind of equilibrium arm connecting device of Mini-tower hoist tool, and particularly the oblique back stay connecting device of a kind of Mini-tower hoist tool, belongs to hoisting crane manufacturing technology field.
Background technology
Tower crane tower crane is called for short tower machine, also claims tower crane, and its crane arm is contained in the rotary crane on towering tower body top.Working space is large, is mainly used in the installation of vertical and horizontal feed and the building element of material in housing construction.By metal construction, operating mechanism and electric system three parts, formed.Metal construction comprises tower body, crane arm and base etc.Operating mechanism hoists, luffing, revolution and walking four parts.Electric system comprises electrical motor, controller, electric power distribution cabinet, connection line, signal and illumination equipment etc.
Between the common oblique back stay of Mini-tower hoist tool and equilibrium arm, by free bearing, be directly connected, tiltedly action without spin between back stay and equilibrium arm, if rotated, can produce laterodeviation wearing and tearing.During transportation oblique back stay can not folds flat on equilibrium arm.In recent years, three layers and with storied building, residential building, in the small building constructions such as low layer industrial building, adopts universal building tower crane more, install, transportation and conversion building site inconvenient, construction cost is high, operating efficiency is lower.Particularly when new countryside construction is constructed, often need to repeatedly dismantle and install, but after common tower crane dismounting, become a plurality of parts, in transportation, need to carry out transition by other transportation devices, if can increase traffic cost in the more situation that cannot fold placement of parts.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of oblique back stay connecting device of a kind of Mini-tower hoist tool without side wear can guarantee that oblique back stay and equilibrium arm rotate by hinge time.
Technical scheme: the oblique back stay connecting device of a kind of Mini-tower hoist tool, comprise tower cap, equilibrium arm and oblique back stay, equilibrium arm end is articulated with tower cap bottom, tiltedly back stay is connected with the equilibrium arm other end and tower crown portion respectively, described equilibrium arm and tiltedly hinged by rotary type coupling assembling between back stay.By coupling assembling, can guarantee that each connects hinge and in rotatable plane, is bearing unidirectional pulling force separately.In installation and unloading process, hinged place can smooth and easyly be rotated, and in transportation, can realize after oblique back stay folds and lying on equilibrium arm.
Preferred term, described coupling assembling is " work " character form structure, transition tie-beam in the middle of comprising and the connecting panel of both sides, described excessive tie-beam is fixedly connected with the connecting panel of both sides respectively, described connecting panel two ends are respectively equipped with pull bar hinge hole and equilibrium arm hinge hole, described coupling assembling is hinged by equilibrium arm hinge hole and equilibrium arm, hinged with oblique back stay by pull bar hinge hole.By the pull bar hinge hole on connecting panel and equilibrium arm hinge hole, realize equilibrium arm and oblique being connected of back stay, also guaranteed that junction can rotate smoothly simultaneously.
In order further to improve reliability of the present invention, the junction of described transition tie-beam and two side connecting plates is provided with brace panel.
Beneficial effect: the present invention is Mini-tower hoist tool installs, dismantles the connecting device that equilibrium arm provides flexibility and reliability certainly, make former fixing connection hinge become rotatable connection hinge, realized by oblique back stay smoothly cocked or rotation put down equilibrium arm and on mechanism, structure member, reduced to greatest extent installation and the dismantlement work amount of installation, dismounting and transportation operating mode; Also make the conversion of installing, dismantling and transporting operating mode become faster.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged view of junction of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the oblique back stay connecting device of a kind of Mini-tower hoist tool, comprise tower cap 1, equilibrium arm 2 and oblique back stay 3, equilibrium arm 2 ends are articulated with tower cap 1 bottom, tiltedly back stay 3 is connected with equilibrium arm 2 other ends and tower cap 1 top respectively, described equilibrium arm 2 and tiltedly hinged by rotary type coupling assembling 4 between back stay 3.By coupling assembling 4, can guarantee that each connects hinge and in rotatable plane, is bearing unidirectional pulling force separately.In installation and unloading process, hinged place can smooth and easyly be rotated, and in transportation, can realize after oblique back stay 3 folds and lying on equilibrium arm 2.
As shown in Figure 2, described coupling assembling 4 is " work " character form structure, transition tie-beam 41 in the middle of comprising and the connecting panel 42 of both sides, described excessive tie-beam 41 is fixedly connected with the connecting panel 42 of both sides respectively, described connecting panel 42 two ends are respectively equipped with pull bar hinge hole 43 and equilibrium arm hinge hole 44, described coupling assembling 4 is hinged by equilibrium arm hinge hole 44 and equilibrium arm 2, hinged with oblique back stay 3 by pull bar hinge hole 43.By the pull bar hinge hole 43 on connecting panel 42 and equilibrium arm hinge hole 44, realize equilibrium arm 2 and oblique being connected of back stay 3, also guaranteed that junction can rotate smoothly simultaneously.
In order further to improve reliability of the present invention, the junction of described transition tie-beam 41 and two side connecting plates 42 is provided with brace panel 45.
The present invention is Mini-tower hoist tool installs, dismantles the connecting device that equilibrium arm 2 provides flexibility and reliability certainly, make former fixing connection hinge become rotatable connection hinge, realized by oblique back stay 3 smoothly cocked or rotation put down equilibrium arm 2 and on mechanism, structure member, reduced to greatest extent installation and the dismantlement work amount of installation, dismounting and transportation operating mode; Also make the conversion of installing, dismantling and transporting operating mode become faster.
