Abstract
The utility model discloses a kind of derrick runway girder rob support, comprise the support be integrally welded, it comprises left socle (4), middle bracket (6) and right support (5); Left socle (4) is welded into as a whole by middle bracket (6) and right support (5), and left socle (4) and right support (5) bottom all have bolt hole, is fixed between the two by a bolt (3); Frame upper supports weighing arm pull bar by middle bracket (6), and middle bracket (6) and bottom bolts (3) snap in and hanging stick on fastening crane arm; Original upper bracket lower bracket carries out being integrated into a support by the utility model, uses a bolt to complete fixing, reaches structure and simply install object easily.
Description
Technical field
The utility model relates to a kind of derrick runway girder pull bar, specifically a kind of derrick runway girder rob support.
Background technology
Tower top formula tower machine all needs pulling-rod frame on crane arm when dismounting crane arm, at this moment will need rob support: be arranged on a kind of device of crane arm top boom for interim bracket crane arm pull bar, usually can arrange at interval of certain distance on crane arm by several rob support; Because crane arm pull bar is that a kind of joint number is a lot of and length is very long its one end of framing member is connected the other end by bearing pin and crane arm and is connected with tower top by bearing pin, as not having rob support, then when dismounting crane arm, pull bar can hang down.Particularly when field-strip, if do not have rob support, then pull bar has the danger of putting to fall to hurting sb.'s feelings.If there is no rob support during installation, bring great trouble can to the installation of pull bar.Therefore, very necessary for a simple and practical rob support being convenient to install of middle-size and small-size tower machine design.
At present conventional support as shown in Figure 1, uses the welding such as a steel plate combination gusset upper bracket 1, wherein on upper bracket 1 floor with 4 bolts hole, with Plate Welding lower bracket 2, also with four bolts hole; Penetrate 4 bolts 3 also suitably fastening, then rob support is securely connected at crane arm top boom, and during use, crane arm pull bar drops in the groove of upper bracket 1.But this structure pull bar support is divided into upper bracket 1 and lower bracket 2 two parts, need four bolts 3 to connect during connection, detachable part is too many, is to make, get ready the goods or install all relatively to bother, and when mounted, needs to install fastening four bolts 3, relatively loaded down with trivial details.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of derrick runway girder rob support, and structure is simple, it is convenient to install, and can meet the operating needs of dismounting.
To achieve these goals, the technical solution adopted in the utility model is: a kind of derrick runway girder rob support, comprises the support be integrally welded, and it comprises left socle, middle bracket and right support;
Left socle is welded into as a whole by middle bracket and right support, and left socle and right support bottom all have bolt hole, is fixed between the two by a bolt;
Frame upper supports weighing arm pull bar by middle bracket, and middle bracket and bottom bolts snap in and hanging stick on fastening crane arm.
Described left socle and right Zhi Shangduan are Open architecture.
On described middle bracket length and crane arm, hanging stick width matches.
Middle bracket and crane arm pull bar contact position are also provided with cushion block.
Compared with existing support, structure is simple, economical and practical, it is convenient to install, and only uses a bolt can complete connection and meets operating needs.Because crane arm rob support only uses when the dismounting of tower machine, the number of times used in the whole life cycle of tower machine is very few, especially for middle-size and small-size tower machine, crane arm pull bar weight is relatively little, supporting structure does not need to bear too many power, and therefore the rob support of this simple structure can meet the demands completely.
Accompanying drawing explanation
Fig. 1 is existing supporting structure schematic diagram;
Fig. 2 is the utility model structural representation.
In figure: 1, upper bracket, 2, lower bracket, 3, bolt, 4, left socle, 5, right support, 6, middle bracket.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of derrick runway girder rob support, comprises the support be integrally welded, and it comprises left socle 4, middle bracket 6 and right support 5;
Left socle 4 is welded into as a whole by middle bracket 6 and right support 5, and left socle 4 and right support 5 bottom all have bolt hole, is fixed between the two by a bolt 3;
Frame upper supports weighing arm pull bar by middle bracket 6, and middle bracket 6 and bottom bolts 3 snap in and hanging stick on fastening crane arm.
Described left socle 4 and right support 5 upper end are Open architecture, are convenient to crane arm pull bar and put into.
On described middle bracket 6 length and crane arm, hanging stick width matches, and tightly blocks hanging stick on crane arm by coordinating with bottom bolts 3.
Middle bracket 6 and crane arm pull bar contact position are also provided with cushion block, increase friction, reduce the wearing and tearing to middle bracket 6.
The utility model structure is simple, economical and practical, it is convenient to install, and only uses a bolt 3 can complete connection and meets operating needs, and because crane arm rob support only uses when the dismounting of tower machine, the number of times used in the whole life cycle of tower machine is very few.Especially for middle-size and small-size tower machine, crane arm pull bar weight is relatively little, and supporting structure does not need to bear too many power, and therefore the rob support of this simple structure can meet the demands completely.
