Abstract
The utility model discloses an outer ear plate of a tower crane pin roll connecting tower body standard knot. The outer ear plate of the tower crane pin roll connecting tower body standard knot comprises an inner ear body (111), and a hanger (121) is arranged at the upper end of the outer ear body (1). A connecting portion (121) is arranged at the opposite end of the outer ear body (1). The outer ear plate of the tower crane pin roll connecting tower body standard knot is characterized in that the outer ear body (1) is made of carbon structural steel materials of a mark of Q235B. The outer 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 outer 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 adopts No. 35 Steel materials to make when producing otic placode usually, 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 outer otic placode that tower machine bearing pin connects tower-body standard section, and this technical scheme has efficiently solved connective stability and the poor problem of welding performance between the outer otic placode between the standard knot of tower machine body of the tower.
The utility model is achieved through the following technical solutions:
Tower machine bearing pin connects the outer otic placode of tower-body standard section, comprises outer otic placode body 1, and outer otic placode body 1 upper end is provided with hangers 111, and the opposite end is connecting portion 121, it is characterized in that: described outer otic placode body 1 is that the carbon structure Steel material of Q235B is made by the trade mark.
The further Technological improvement plan of the utility model is:
Be arc-shaped transition section 13 between described outer otic placode body 1 top 11 and the bottom 12.
The further Technological improvement plan of the utility model is:
The top 11 of described outer otic placode body 1 is provided with hangers 111, and bottom 12 is connecting portion 121.
The utility model compared with prior art, have following obvious advantage: the outer 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 outer otic placode and the standard knot, thereby improved the stability that connects between the standard knot, between the outer otic placode body top of the utility model and the bottom arc-shaped transition section is set simultaneously, is convenient to the better docking between each standard knot.
Description of drawings
Fig. 1 is main TV structure scheme drawing 1 of the present utility model;
Fig. 2 is left TV structure scheme drawing 1 of the present utility model.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises outer otic placode body 1, outer otic placode body 1 upper end is provided with hangers 111, the opposite end is connecting portion 121, described outer otic placode body 1 is that the carbon structure Steel material of Q235B is made by the trade mark, be arc-shaped transition section 13 between described outer otic placode body 1 top 11 and the bottom 12, the top 11 of described outer otic placode body 1 is provided with hangers 111, and bottom 12 is connecting portion 121.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
