Abstract
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.Beneficial effect: what the utility model was Mini-tower hoist tool installs, dismantles equilibrium arm certainly provides the connecting device of flexibility and reliability, 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 transport operating mode; Also make the conversion of installing, dismantle and transporting operating mode become faster.
Description
Technical field
This utility model 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.Formed by metal construction, operating mechanism and electric system three parts.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, be directly connected by free bearing, tiltedly action without spin between back stay and equilibrium arm, if rotated, can produce laterodeviation wearing and tearing.When transport 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, installs, transport and conversion building site inconvenience, and construction cost is high, and operating efficiency is lower.Particularly in the time that new countryside construction is constructed, often need to repeatedly dismantle and install, but after the dismounting of common tower crane, become multiple 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 purpose of this utility model is to provide a kind of oblique back stay connecting device of a kind of Mini-tower hoist tool without side wear can ensure 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 " work " font coupling assembling between back stay.Can ensure that by coupling assembling each connection hinge is bearing unidirectional pulling force in rotatable plane 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.Transition tie-beam in the middle of described coupling assembling comprises and the connecting panel of both sides, described transition 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.Realize equilibrium arm and oblique being connected of back stay by the pull bar hinge hole on connecting panel and equilibrium arm hinge hole, also ensured that junction can rotate smoothly simultaneously.
In order further to improve reliability of the present utility model, the junction of described transition tie-beam and two side connecting plates is provided with brace panel.
Beneficial effect: what the utility model was Mini-tower hoist tool installs, dismantles equilibrium arm certainly provides the connecting device of flexibility and reliability, 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 transport operating mode; Also make the conversion of installing, dismantle and transporting operating mode become faster.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view of the utility model junction.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
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 " work " font coupling assembling 4 between back stay 3.Can ensure that by coupling assembling 4 each connection hinge is bearing unidirectional pulling force in rotatable plane 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 transition 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.Realize equilibrium arm 2 and oblique being connected of back stay 3 by the pull bar hinge hole 43 on connecting panel 42 and equilibrium arm hinge hole 44, also ensured that junction can rotate smoothly simultaneously.
In order further to improve reliability of the present utility model, the junction of described transition tie-beam 41 and two side connecting plates 42 is provided with brace panel 45.
What the utility model was Mini-tower hoist tool installs, dismantles equilibrium arm 2 certainly provides the connecting device of flexibility and reliability, 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 transport operating mode; Also make the conversion of installing, dismantle and transporting operating mode become faster.
