Description

The telescopic attaching frame of a kind of double leval jib
Technical field
The utility model relates to tower machine technology field, refers in particular to the telescopic attaching frame of a kind of double leval jib.
Background technology
Tower crane is the main heavy mechanical equipment in building ground, be responsible for the vital task of vertical transport, along with the continuous rising of depth of building, when the use of tower crane highly exceedes the unattached height of its regulation, must according to the regulation of tower crane service instructions, building is arranged attachment device (namely tower crane tower body and building between adopt rigid components to socket), to meet the strength and stability requirement of tower crane.When being especially elevated framework, lifting runs not steadily, attachment device inconvenient operation, there is larger potential safety hazard, brings very large difficulty to the tower crane work in building construction process.Tower machine all must use attaching frame after exceeding independent use height, and be connected with building by tower body, improve the stability of tower machine, the height that tower machine uses is higher, and the quantity of attaching frame is also more.Attaching frame itself is motionless in addition, and after just having added attaching frame, the height of tower machine could increase again.If only increase the height of tower machine, and do not increase attaching frame, just there is the machine of falling tower dangerous.。
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and is elevated the telescopic attaching frame of steady, easy to operate, practical double leval jib.
For achieving the above object, technical scheme provided by the utility model is: the telescopic attaching frame of a kind of double leval jib, it includes pedestal, framework, framework free bearing, wherein, framework free bearing is two, is bolted on pedestal respectively by corresponding free bearing, and framework free bearing two ends epirelief forms hinge position, connected by recessed arc contiguous block between two hinge positions, hinge position is provided with fraising; Framework is assemblied on framework free bearing by shrinking connecting-rod, the square frame-shaped that chassis body is become relative to assembly by some channel-section steels, and the base of frame after combination is provided with lower free bearing vertically downward, and frame roof both sides are provided with free bearing; Shrinking connecting-rod is made up of first, second, third, fourth connecting rod, wherein, first, second connecting rod one end is hinged on the fraising inside framework free bearing, the other end is upwards hinged with the lower free bearing of base of frame both sides, three, double leval jib one end is connected with reaming outside corresponding framework free bearing respectively, and the 3rd, the double leval jib other end is upwards hinged with the upper free bearing of frame roof both sides respectively; The length of first, second connecting rod is less than the 3rd, the length of double leval jib, and the framework after assembling is perpendicular between two framework free bearings.
Distance between two described framework free bearings is greater than lengths of frame.
The utility model, after employing such scheme, makes first, second, third, fourth connecting rod formation interlock by framework free bearing, is synchronously elevated framework, by framework lifting operation more steadily, reliably; By pinned connection after inside and outside strut regulates, safe and reliable; As long as this attaching frame in the setting range of this attaching frame, is all used to the distance of building girder in Ta Ji center.As long as outside connecting rod in adjustment, and the adjusting screw(rod) of one end, can obtain different installation dimensions, facilitate building operation, and the commonality of attaching frame; The structure lifting of this programme is steady, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, the telescopic attaching frame of double leval jib described in the present embodiment includes pedestal 1, framework 4, framework free bearing 5, wherein, framework free bearing 5 is two, is fixed on pedestal 1 respectively by corresponding free bearing bolt 2, and framework free bearing 5 two ends epirelief forms hinge position, connected by recessed arc contiguous block between two hinge positions, hinge position is provided with fraising; Framework 4 is assemblied on framework free bearing 5 by shrinking connecting-rod, the square frame-shaped that framework 4 main body is become relative to assembly by some channel-section steels, is provided with lower free bearing 6 vertically downward bottom the framework 4 after combination, and both sides, framework 4 top are provided with free bearing 7; Shrinking connecting-rod is made up of first, second, third, fourth connecting rod 8,9,10,11, wherein, first, second connecting rod 8,9 one end is hinged on the fraising inside framework free bearing 5, the other end is upwards hinged with the lower free bearing 6 of framework 4 two bottom sides, three, double leval jib 10,11 one end is connected with reaming outside corresponding framework free bearing 5 respectively, and the 3rd, double leval jib 10,11 other end is upwards hinged with the upper free bearing 7 of both sides, framework 4 top respectively; The length of first, second connecting rod 8,9 is less than the 3rd, the length of double leval jib 10,11, and the framework 4 after assembling is perpendicular between two framework free bearings 5; Distance between two described framework free bearings 5 is greater than framework 4 length.The utility model, after employing such scheme, makes first, second, third, fourth connecting rod formation interlock by framework free bearing, is synchronously elevated framework, by framework lifting operation more steadily, reliably; By pinned connection after inside and outside strut regulates, safe and reliable; As long as this attaching frame in the setting range of this attaching frame, is all used to the distance of building girder in Ta Ji center.As long as outside connecting rod in adjustment, and the adjusting screw(rod) of one end, can obtain different installation dimensions, facilitate building operation, and the commonality of attaching frame; The structure lifting of this programme is steady, easy to operate, practical.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
