Abstract
The utility model relates to a connecting structure of a wrap frame and a lower supporting seat of a tower crane, which is characterized by comprising a taper connector fixed on the wrap frame, and an inclined plate which is fixed at the position of the inner wall of the lower supporting seat, which is connected and matched with the taper connector, and the taper connector is arranged in the lower supporting seat. The utility model has the advantages that no eccentric phenomenon is caused in installation, natural and horizontal installation is carried out, and the installing speed and the safety coefficient of the tower crane can be improved.
Description
Technical field
The utility model relates to the connection structure of a kind of tower crane stock and undersetting, avoids having an accident in the tower crane installation process, makes the safer installation of tower crane.
Background technology
As shown in Figure 1, be the traditional tower crane stock and the connection structure scheme drawing of undersetting, the described traditional tower crane stock and the connection structure of undersetting, stock 2 connects undersetting 1 by dull and stereotyped joint 5, dull and stereotyped joint 5 inserts in the undersetting 1, and dull and stereotyped joint 5 is fixed on the stock 2.Because adopting, the junction of undersetting and stock faces cooperation directly, so no matter be that undersetting or stock are as long as wherein a side has off-centre in installation process, will cause undersetting and stock to cooperate, if top firmly can drop stock because oil cylinder is exerted oneself excessive or tower crane such as knocks at the safety misadventure generation.
Summary of the invention
The purpose of this utility model provides a kind of easy for installation and can improve the undersetting and the stock ways of connecting of the safety factor when installing.
In order to achieve the above object, the utility model provides the connection structure of a kind of tower crane stock and undersetting, it is characterized in that, comprises the tapering joint that is fixed on the stock, and the tapering joint is located in the undersetting.
Further, be connected the cooperation place with the tapering joint on the described undersetting inwall and be fixed with swash plate.
The utility model has the advantages that: do not have the accentric phenomenon during installation, parallel naturally packing into, improved the installation rate and the safety factor of tower crane.
Description of drawings
Fig. 1 is the traditional tower crane stock and the connection structure scheme drawing of undersetting;
Fig. 2 is a B place enlarged drawing among Fig. 1;
Fig. 3 is the connection structure scheme drawing of tower crane stock of the present utility model and undersetting;
Fig. 4 is a B place enlarged drawing among Fig. 3.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 3, connection structure scheme drawing for tower crane stock of the present utility model and undersetting, Fig. 4 is a B place enlarged drawing among Fig. 3, the connection structure of described tower crane stock and undersetting is made up of tapering joint 4 and swash plate 5, tapering joint 4 is fixed on the stock 2, swash plate 5 is welded on to be fixed on undersetting 1 inwall and is connected the cooperation place with tapering joint 4, and tapering joint 4 inserts in the undersetting 1.When being connected with undersetting 1 when cooperating, stock 2 just can be combined together very smoothly like this, even the accentric phenomenon occurs, tapering joint 4 also can slowly be connected cooperation with undersetting 1 along swash plate 5, the safety factor when so not only having increased installation rate but also having increased installation.
Claims (2)
1. the connection structure of tower crane stock and undersetting is characterized in that comprise the tapering joint (4) that is fixed on the stock (2), tapering joint (4) is located in the undersetting (1).
2. the connection structure of tower crane stock as claimed in claim 1 and undersetting is characterized in that, is connected the cooperation place with tapering joint (4) on described undersetting (1) inwall and is fixed with swash plate (5).
