Description
Technical field
The utility model relates to elevators fields, and in particular to a kind of jacknife mast.
Background technique
Being constantly progressive and develop with society, the raising of people's living standard, skyscraper is increasing, and elevator becomes
The indispensable vehicles between building.In the installation of elevator, need to transport the derrick of elevator, due to traditional
The particularity of derrick geometry, accumulation rate is low during transportation for traditional derrick, and construction efficiency is lower, and installation accuracy is lower, time-consuming
Arduously.
Utility model content
In order to solve the above technical problems, accumulation rate is high during transportation for the derrick we have proposed a kind of jacknife mast,
Construction efficiency is high, and installation accuracy is high, time saving and energy saving.
In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of jacknife mast, including four derrick columns,
Four derrick beams, eight pin shafts and multiple fixing bolts；The square setting of four derrick beams, four derrick beams four
The derrick column is respectively arranged at angle, the both ends of the derrick beam pass through the pin shaft and the derrick column hinge respectively
Connection, the pin shaft two sides respectively symmetrically offer fixing threaded hole, the fixing bolt are provided in the fixing threaded hole.
Further, the derrick column is rectangular parallelepiped structure.
Further, the both ends of the derrick beam are connect with the two sides hinge of the derrick column respectively.
Further, the junction of the derrick beam and the derrick column is by two pieces of connecting plate overlappings and the pin shaft
Cooperation carry out hinge connection.
Further, the fixing bolt is separately positioned on the junction of the derrick beam Yu the derrick column.
Through the above technical solutions, the utility model is connect with derrick column by the pin hinge by the derrick beam,
The jacknife mast is in "-" type in the way of transport, transports to after erecting bed, is rotated by 90 ° and is square, then passes through institute
It is fixed to state fixing bolt, the jacknife mast structure is simple, and production and processing is simple, derrick accumulation rate during transportation
Height, construction efficiency is high, and installation accuracy is high, and time saving and energy saving, application effect is splendid.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Structural schematic diagram when Fig. 1 is a kind of installation of jacknife mast disclosed in the utility model embodiment；
Structural schematic diagram when Fig. 2 is a kind of transport of jacknife mast disclosed in the utility model embodiment.
In figure: 1, derrick column 2, derrick beam 3, pin shaft 4, fixing bolt
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model is described in further detail below with reference to embodiment and specific embodiment.
As depicted in figs. 1 and 2, a kind of jacknife mast, including four 1, four, derrick column, 2, eight, derrick beam pin shafts 3 and more
A fixing bolt 4；The square setting of four derrick beams 2, four derrick beams, 2 four corners are respectively arranged with an institute
Derrick column 1 is stated, the both ends of the derrick beam 2 pass through the pin shaft 3 respectively and connect with 1 hinge of derrick column, 3 liang of the pin shaft
Side respectively symmetrically offers fixing threaded hole, and the fixing bolt 4 is provided in the fixing threaded hole.
The derrick column 1 is rectangular parallelepiped structure.
The both ends of the derrick beam 2 are connect with the two sides hinge of the derrick column 1 respectively.
The junction of the derrick beam 2 and the derrick column 1 is the cooperation by two pieces of connecting plates overlappings and the pin shaft 3
Carry out hinge connection.
The fixing bolt 4 is separately positioned on the junction of the derrick beam 2 and the derrick column 1.
Through the above technical solutions, the utility model is connected with derrick column 1 by 3 hinge of pin shaft by the derrick beam 2
It connects, which is in "-" type in the way of transport, transports to after erecting bed, is rotated by 90 ° and is square, then leads to
It is fixed to cross the fixing bolt 4, the jacknife mast structure is simple, and production and processing is simple, which accumulates during transportation
Rate height is deposited, construction efficiency is high, and installation accuracy is high, and time saving and energy saving, application effect is splendid.
Above-described is only a kind of jacknife mast preferred embodiment of the utility model, it is noted that for ability
For the those of ordinary skill in domain, without departing from the concept of the present invention, can also make it is several deformation and
It improves, these are all within the protection scope of the present invention.
