Description
Technical Field
The utility model relates to a tow chain supports and fixing device among dolly tow chain power supply system, more specifically says, relates to a detachable tow chain support.
Background
As shown in fig. 1, the bracket 1 of the conventional trolley drag chain system is directly welded to the steel structure 2, and the design scheme has the following disadvantages:
1) because the conventional bracket is overlapped by using angle steel, in order to increase the stability of the bracket structure, one support of the bracket needs to be welded at the edge of the steel structure, but the area is positioned in a high stress area of the main structure, the stress concentration is large, and the influence on the fatigue strength is large;
2) the manufacturing problems of secondary fire and secondary coating of a welding area of the structure are caused on a welding structure of the welding type bracket;
3) when the position of the drag chain row is required to be adjusted, the drag chain row is difficult to adjust, and the bracket is often integrally cut for adjustment;
4) in the use, if the support goes wrong, the maintenance is inconvenient, the whole support needs to be replaced, and the support is welded at high altitude.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a detachable tow chain support solves current welding stent and produces tired problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a detachable drag chain support is connected to a steel structure and comprises a cross rib base connected to the steel structure and a support main body connected to the lower end of the cross rib base;
the cross rib base comprises a first rib plate, and a second rib plate and a third rib plate which are respectively vertically connected to two side surfaces of the first rib plate in a mirror symmetry manner, the top ends of the first rib plate, the second rib plate and the third rib plate are all connected with the steel structure, and the bottom ends of the first rib plate, the second rib plate and the third rib plate are all connected with an upper flange;
the support main body comprises a support body, a lower flange is connected to the top end of the support body, the lower flange is connected with the upper flange, a fourth rib plate and a fifth rib plate are respectively connected between the two side faces of the top end of the support body and the lower surface of the lower flange, and a chassis is connected to the bottom of the support body.
The lower flange is connected with the upper flange through bolts and nuts.
Stress holes are formed in the upper ends of the second rib plate, the third rib plate, the fourth rib plate and the fifth rib plate.
And a base plate is also arranged between the lower flange and the upper flange.
The support main part is made for the channel-section steel material.
In the technical scheme, the utility model provides a detachable tow chain support, cross muscle base through upper portion is as an organic whole with steel construction welding, solves the fatigue strength problem of support, and the support main part of lower part adopts the channel-section steel, increases the intensity and the stability of structure. The lower flange is connected with the upper flange through bolts, so that the problems of secondary fire striking and secondary coating manufacturing of the bracket in the installation process can be solved. The overall height difference of the support can be adjusted by increasing the base plate of the cross rib and the support main body. When the support main part goes wrong in the use, the support main part of lower part is placed on the ground for maintenance through dismantling the bolt, and the problems of high altitude welding and the like are avoided.

Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
Please refer to fig. 2 to 7, the present invention provides a detachable drag chain support, which is connected to the steel structure 2, the support of the present invention includes a cross-shaped rib base connected to the steel structure 2 and a support body connected to the lower end of the cross-shaped rib base, wherein the cross-shaped rib base on the upper portion is welded to the middle of the steel structure 2, so as to solve the fatigue strength problem of the support.
The cross rib base comprises a first rib plate 3, a second rib plate 4 and a third rib plate 5 which are respectively vertically connected to two side faces of the first rib plate 3 in a mirror symmetry mode, the top ends of the first rib plate 3, the second rib plate 4 and the third rib plate 5 are connected with a steel structure 2, and the bottom ends of the first rib plate 3, the second rib plate 4 and the third rib plate 5 are connected with an upper flange 6.
The support main body comprises a support body 7, a lower flange 8 is connected to the top end of the support body 7, the lower flange 8 is connected with an upper flange 6 through bolts and nuts 9, a fourth rib plate 10 and a fifth rib plate 11 are respectively connected between the two side faces of the top end of the support body 7 and the lower surface of the lower flange 8, and a chassis 12 is connected to the bottom of the support body 7. The lower flange 8 is connected with the upper flange 6 through bolts and nuts 9, and the problems of secondary fire striking and secondary coating manufacturing of the bracket in the installation process can be solved.
