Abstract
The utility model discloses an inner ear plate of a tower crane pin roll connecting tower body standard knot. The inner ear plate of the tower crane pin roll connecting tower body standard knot comprises an inner ear body (1), and hangers (1111, 1211) are arranged on the inner ear body (1). The inner ear plate of the tower crane pin roll connecting tower body standard knot is characterized in that the inner ear body (1) is made of carbon structural steel materials of a mark of Q235B, and the cross section is of triangle shape. The inner ear plate of the tower crane pin roll connecting tower body standard knot effectively solves the problems of poor continuous stability and welding performance between standard knots of a tower body of a tower crane.
Description
Technical field
The utility model relates to tower machine component device technical field, is specifically related to the interior otic placode that tower machine bearing pin connects tower-body standard section.
Background technology
The tower machine, it is our said tower crane, be called again tower crane, it is a kind of weight-lifting equipment for building operation, the body of the tower of tower machine is made of a plurality of standard knots usually, between each standard knot all by otic placode connection fastened to each other, therefore the making material of otic placode can directly have influence on the stability of body of the tower, at present, tower machine manufacturing enterprise in producing during otic placode usually No. 35 Steel materials of employing make, because No. 35 Steel materials are not easy to punching press, and the welding performance of itself is relatively poor, has brought certain potential safety hazard for production and the use of tower machine.
Summary of the invention
The technical problems to be solved in the utility model provides the interior otic placode that tower machine bearing pin connects tower-body standard section, connective stability and the poor problem of welding performance in this technical scheme has efficiently solved between the standard knot of tower machine body of the tower between the otic placode.
The utility model is achieved through the following technical solutions:
Tower machine bearing pin connects the interior otic placode of tower-body standard section, comprise interior otic placode body 1, interior otic placode body 1 is provided with hangers 1111,1211, connecting portion, it is characterized in that: described interior otic placode body 1 is that the carbon structure Steel material of Q235B is made by the trade mark, and shape of cross section is triangular in shape.
The further Technological improvement plan of the utility model is:
Described interior otic placode body 1 comprises side plate A11, side plate B12.
The further Technological improvement plan of the utility model is:
The top 111 of described side plate A11 is provided with hangers A1111, and the bottom is connecting portion A112; The top 121 of described side plate B12 is provided with hangers B1211, and the bottom is connecting portion B122.
The utility model compared with prior art, have following obvious advantage: the interior otic placode body employing of the utility model trade mark is that the carbon structure Steel material of Q235B is made, the carbon structure Steel material of Q235B possesses preferably percentage elongation, intensity, good toughness and castability, be easy to pressing and jointing, improved the weld strength between interior otic placode and the standard knot, thereby improved the stability that connects between the standard knot, the otic placode body cross-section adopts triangle in the utility model simultaneously, be convenient to the better docking between each standard knot, also improved the connective stability between the standard knot simultaneously.
Description of drawings
Fig. 1 is structural representation one of the present utility model;
Fig. 2 is structural representation two of the present utility model.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises interior otic placode body 1, and interior otic placode body 1 is provided with hangers 1111,1211, connecting portion, and interior otic placode body 1 is that the carbon structure Steel material of Q235B is made by the trade mark, and shape of cross section is triangular in shape; Interior otic placode body 1 comprises side plate A11, side plate B12; The top 111 of side plate A11 is provided with hangers A1111, and the bottom is connecting portion A112; The top 121 of side plate B12 is provided with hangers B1211, and the bottom is connecting portion B122.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
