Description
Technical field
The present invention relates to a kind of New-type plate fish tail board component, be particularly suitable for use in tower crane.
Background technology
At present, it is widely used in the derrick crane in construction project, the main load bearing component of its short transverse is by all
The tower body that multi-standard section is combined.Wherein, most commonly seen, bearing capacity standard knot type of attachment the most reliable is used
Fish platee type of attachment, as shown in Fig. 1, Fig. 3, Fig. 4.
But it is regrettably, complex due to fabricating, cause the cost of fish platee relatively high.Except big
Type, high-end tower crane are obtained outside more application, in general middle or small tonnage, the tower crane of common class, then be typically with
Adapter sleeve, the mode of bolt connection pair carry out standard knot connection, as shown in Figure 3.The normal of standard knot tower body can so be ensured
Carrying, can reach again reduces the purpose of cost, and better quality products at good values, more presses close to the demand of normal client, therefore
Application is widely.And, it is necessary to possess preferable mechanical process capacity, from examining for manufacturing cost in the manufacturing process of fish platee
Consider, in, the standard knot of trourelle is using fish platee when being connected, more high processing is not often born by client.
In order to which the fish platee type of attachment being generally used for large-tonnage tower crane, function is excellent is promoted, common shelves are applied to
In the tower crane of secondary middle or small tonnage, to reach on the premise of facilitating user, ensureing use, the purpose of manufacturing cost, root are reduced
A kind of new board-like fish tail board component is developed according to above-mentioned thinking.
The content of the invention
For above-mentioned existing technical problem, the present invention provides a kind of New-type plate fish tail board component, has exclusively carried out mark
The improvement of quasi- section type of attachment, with the improvement for the market adaptability for improving tower crane, while widening the standard knot linked vector graph in tower
The application coverage of machine tonnage.
To achieve the above object, the present invention provides a kind of New-type plate fish tail board component, including two board-like fish platees, both
Bottom is connected to the top of adjacent two lateral surface of main string, and in one high and one low arrangement, both top is respectively equipped with
At least two connection pin shaft holes；When two main strings connections up and down, the board-like fish platee of the main string in lower section by connect bearing pin with it is upper
The bottom of the main string in side is fixedly connected.
In order to keep easy to connect, ensure bearing function, this board-like fish platee employs the connected mode of many bearing pins, and together
Two board-like fish platees on one main string are arranged in height so that the controlled area increase of connection bearing pin, are connected more firm.
Further, the top of described board-like fish platee 2 is rectangular configuration, and bottom is inverted trapezoidal structure.
Further, main string uses angle steel or square steel tubular construction.Tower crane maximum load power determine in the case of, in, trourelle
Tower body can easily be assembled using such a standard section main string, make that the early stage of tower crane is installed, later stage dismantlement work is significantly reduced.
The present invention uses New-type plate fish platee and pin shaft connection structure, and uses based on the section bars such as angle steel, square steel tube
String, possesses the advantages of being easy to buying, manufacture convenient for production, install in place accurate, and the standard knot of tower crane can be made to connect more square
Just, rationally, easy system, practical, reach on the premise of adapter sleeve, the standard knot manufacturing cost of bolt pair form is not significantly improved,
It will be promoted the use of with connection reliability, fish platee structure easy to use on the standard knot of common middle or small tower crane.It is specific excellent
Point is described below：
1st, structure type is easily achieved.Structure construction is relatively easy, and is substituted commonly using the manufacturing method of plate thereof of excellent material
The fish platee of material forging molding so that the processing and manufacturing cost of board-like fish platee is full less than the manufacturing cost for forging fish platee
The foot demand in market.
2nd, install and safeguard more convenient.The mounting characteristic of bearing pin connection, installation compared with adapter sleeve auxiliary connection, is safeguarded and not
Need the complicated operation that high-altitude is tightened so that tower body it is easier for installation.
3rd, it is wider using coverage.Because the construction theory and fish platee of the standard knot of angle steel or the main beam string structure of square steel tube
Structure type is more similar, and the application of the standard knot of the main string of angle steel, square steel tube so that this component coverage is wider
It is general, therefore this component is applied to various lifting tonnages, multiple section tower body.
By the application of the technology, the convenience of tower crane is improved, the awareness of client is improved, the adaptability of product is obtained
Certain raising is arrived.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 5, New-type plate fish tail board component of the present invention includes two board-like fish platees 2, board-like fish platee 2 it is upper
Portion is rectangular configuration, and bottom is inverted trapezoidal structure.
The bottom of two board-like fish platees 2 is connected to the top of adjacent two lateral surface of main string, and in one high and one low
Arrangement, the top of two board-like fish platees 2 is respectively equipped with least two connection pin shaft holes.When two main string connections up and down,
The board-like fish platee 2 of the main string in lower section is fixedly connected by connecting the bottom of the main string in bearing pin 3 and top.As shown in fig. 6, in order to keep
Easy to connect, guarantee bearing function, new board-like fish platee employs the connected mode of double pin axle.
Also, the main string of standard knot uses angle steel or square steel tubular construction so that this component coverage is more extensive.
To sum up, the technology of the present invention has fully demonstrated rational in infrastructure, and manufacturing process is easily achieved；From structure construction, production system
Consideration is made, with advantage practical, that adaptation marketability is strong.During manufacture and use, using board-like fish platee structural type
Formula and bearing pin connection so that the installation capability of standard knot is improved, and is provided for producers, product operation person more good
Mounting process, be that tower crane is safely and conveniently used, have laid a good foundation.Meanwhile, have one to the design of other products
Fixed reference value.
