Abstract
The utility model discloses a kind of otic placode connection device, comprise monaural plate and bi-lug plate, described monaural plate is fixed with angle steel, described angle steel opening is towards bi-lug plate, two medial surfaces of described angle steel are all tangent with the arc surface of bi-lug plate side, described monaural plate and bi-lug plate are equipped with connecting bore, and the connecting bore of described monaural plate is concentric with the connecting bore of bi-lug plate, and described monaural plate is fixedly connected with bi-lug plate.When monaural plate is connected with bi-lug plate, the arc surface of bi-lug plate is directly made to contact with two medial surfaces on equal angle are tangent respectively, thus just ensure that monaural plate is concentric with the connecting bore of bi-lug plate, directly penetrate connection bearing pin, just achieve the connection of monaural plate and bi-lug plate.The beneficial effects of the utility model are: 1) structure is simple, easy to make; 2) effectively reduce aloft work labour intensity, make the safety of construction and installation higher; 3) installation effectiveness of equipment is substantially increased.
Description
Technical field
The utility model relates to a kind of otic placode connection device.
Background technology
The installation exercise of tower crane carries out in the air at height.Aloft work work amount is large, and labour intensity is high, causes the operation danger of aloft work person high.And in tower crane installation process, crane arm is respectively saved and connected by otic placode, its work capacity connecting work is very large, for aiming at otic placode connecting bore, conveniently penetrating bearing pin, aiming at otic placode connecting bore operation carrying out again and again, very easily for operator causes fatigue, cause safety misadventure.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of otic placode connection device, and this otic placode connection device is without the need to being again and again alignment pin axis hole and worried, and crane arm is respectively saved connect efficient and convenient, labour intensity is low.
For achieving the above object, the utility model adopts following technical proposals:
A kind of otic placode connection device, comprise monaural plate and bi-lug plate, described monaural plate is fixed with angle steel, described angle steel opening is towards bi-lug plate, two medial surfaces of described angle steel are all tangent with the arc surface of bi-lug plate side, described monaural plate and bi-lug plate are equipped with connecting bore, and the connecting bore of described monaural plate is concentric with the connecting bore of bi-lug plate, and described monaural plate is fixedly connected with bi-lug plate.
The connecting bore of described monaural plate is identical with the connecting bore size of bi-lug plate.
Described monaural plate is fixedly connected with by bearing pin with bi-lug plate, and described bearing pin is through the connecting bore of monaural plate and the connecting bore of bi-lug plate.
Described angle steel is equal angle.
Described monaural plate and bi-lug plate are welded with brace panel, play booster action.
When monaural plate is connected with bi-lug plate, the arc surface of bi-lug plate is directly made to contact with two medial surfaces on equal angle are tangent respectively, thus just ensure that monaural plate is concentric with the connecting bore of bi-lug plate, directly penetrate connection bearing pin, just achieve the connection of monaural plate and bi-lug plate, without the need to being again and again alignment pin axis hole and worried, crane arm is respectively saved connect efficient and convenient, labour intensity is low.
The beneficial effects of the utility model are:
1) structure is simple, easy to make;
2) effectively reduce aloft work labour intensity, make the safety of construction and installation higher;
3) installation effectiveness of equipment is substantially increased.
Accompanying drawing explanation
Fig. 1 is the birds-eye view of the utility model otic placode connection device;
Fig. 2 is the front view of the utility model otic placode connection device;
In figure, 1 is monaural plate, and 2 is bi-lug plate, and 3 is equal angle, and 4 is bearing pin, and 5 is brace panel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Figure 1-Figure 2, otic placode connection device, it comprises monaural plate 1 and bi-lug plate 2, monaural plate 1 welds equal angle 3, equal angle 3 opening is towards bi-lug plate, during equipment making, when making the connecting bore in bi-lug plate 2 and monaural plate 1 connecting bore concentric, on equal angle 3, two medial surfaces contact with the arc surface of bi-lug plate 2 is tangent respectively.Monaural plate 1 is fixedly connected with by bearing pin with bi-lug plate 2.Monaural plate 1 and bi-lug plate 2 are welded with brace panel 5.
When monaural plate 1 is connected with bi-lug plate 2, the arc surface of bi-lug plate 2 is directly made to contact with two medial surfaces on equal angle 3 are tangent respectively, thus just ensure that monaural plate 1 is concentric with the connecting bore of bi-lug plate 2, directly penetrate and connect bearing pin 4, just complete the connection of monaural plate 1 and bi-lug plate 2, without the need to being again and again alignment pin axis hole and worried, crane arm is respectively saved connect efficient and convenient, labour intensity is low.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
