Abstract
The invention discloses a connection structure of a crane arm with a flatted tower top. According to the connection structure, the crane arm is provided with a crane arm single-ear plate (11); the crane arm single-ear plate (11) is connected with a tower top single-ear plate (2) via a single-ear plate connecting plate. The connection structure of the crane arm with the flatted tower top is simple for processing and manufacturing, the crane arm is connected with the flatted tower top via the single-ear plate connecting plate, and processing accuracy is reduced, so that processing and manufacturing are simple; installing is convenient and fast; in installing processes, it is just needed to connect the two ends of the single-ear plate connecting plate with the crane arm and the flatted tower top via pin shafts; installing is flexible, and convenient, and is high in efficient; adjustment is convenient; when the crane arm is connected with the flatted tower top via the single-ear connecting plate, it is convenient and flexible to lift the crane arm to a certain angle to an installing position of a crane arm pull rod.
Description
Technical field
The present invention relates to a kind of crane arm connection structure, specifically a kind of crane arm and cab over type tower top connection structure.
Background technology
It is to be connected with the monaural plate on tower top by crane arm that the crane arm of existing flat-head tower crane is connected with tower top, and this connection request working accuracy is high, is difficult for processing; When installation, also can not guarantee precision, be unfavorable for installing; After installing, crane arm angle of inclination regulates difficulty.
In crane arm and tower top connection procedure, as shown in Figure 1, on crane arm top boom, ears plate 1 directly links together by bearing pin 3 with tower top monaural plate 2, therefore just there will be following technical disadvantages:
1, accuracy of manufacture requirement is high, and this connection mode is high to position, the hole dimension precision requirement of crane arm and tower top upper ear plate, needs to guarantee a lot of original unnecessary degree of precision sizes simultaneously, on manufacturing, increases difficulty;
2, very trouble of installation, in the process connecting in installation, need to be first monaural plate hole co-axially align on ears plate hole and tower top on crane arm, and then squeeze into bearing pin, and crane arm weight is large, and length is long, and while slinging, horizontal equilibrium degree is difficult to control, and installation difficulty increases;
3, be difficult for regulating, after crane arm is arranged on tower top, need lift crane arm and horizon at angle to the installation site of crane arm pull bar again, crane arm is difficult to be regulated, very dumb.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of crane arm and cab over type tower top connection structure, reaches processing and manufacturing simple, easy for installation, quick, the convenient object that regulates crane arm angle of inclination after installing.
To achieve these goals, this crane arm arranges crane arm monaural plate with cab over type tower top connection structure on crane arm, and crane arm monaural plate is connected by monaural plate connecting panel with tower top monaural plate.
Further, described monaural plate connecting panel is provided with two groups.
Further, the two ends of described monaural plate connecting panel all offer respectively the pin-and-hole corresponding with connecting bore on crane arm monaural plate and tower top monaural plate, and connect by bearing pin.
Compared with prior art, this crane arm has following beneficial effect with cab over type tower top connection structure:
1, processing and manufacturing is simple, and crane arm connects by being connected otic placode with tower top, has reduced working accuracy, makes processing and manufacturing very simple;
2, easy for installation, quick, when installation, only need to be connected by bearing pin with crane arm and tower top respectively connecting otic placode two ends, very flexibly, conveniently, efficiently;
3, easily regulate, crane arm is connected to after tower top by connecting otic placode, very convenient, flexible when crane arm lifts certain angle to the installation site of crane arm pull bar, easily regulate.
Accompanying drawing explanation
Fig. 1 is prior art mounting structure schematic diagram;
Fig. 2 is prior art mounting structure partial enlarged drawing;
Fig. 3 is mounting structure schematic diagram of the present invention;
Fig. 4 is mounting structure partial enlarged drawing of the present invention.
In figure: 1, crane arm ears plate, 11, crane arm monaural plate, 2, tower top monaural plate, 3, bearing pin, 4, monaural plate connecting panel.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 3 and Figure 4, this crane arm arranges crane arm monaural plate 11 with cab over type tower top connection structure on crane arm, and crane arm monaural plate 11 is connected by monaural plate connecting panel 4 with tower top monaural plate 2.
Further, described monaural plate connecting panel 4 is provided with two groups, has reduced working accuracy, makes processing and manufacturing very simple, and flexible adjustment is convenient, has guaranteed the intensity connecting simultaneously.
Further, the two ends of described monaural plate connecting panel 4 all offer respectively the pin-and-hole corresponding with connecting bore on crane arm monaural plate 11 and tower top monaural plate 2, and connect by bearing pin 3, easy for installation, quick, the convenient crane arm angle of inclination that regulates.
This crane arm and cab over type tower top connection structure be by increasing transition otic placode between crane arm and tower top are connected, and manufactures processing simple; Easy for installation, fast, very flexible; After crane arm is installed, the angle that easily regulates it to lift.
