Abstract
The utility model discloses a steel pipe leg butt -joint structural of hoist, it includes the ring flange, the bolt is equipped with the round pin axle in the bottom of last steel pipe leg, is equipped with the ring flange in the lower part of last steel pipe leg, is equipped with and sells the pinhole that the axle corresponds at the top of lower steel pipe leg, is equipped with the lower flange dish on the upper portion of lower steel pipe leg, is equipped with the bolt on upper and lower ring flange. The utility model discloses rational in infrastructure, excellent in use effect can be fast, the efficient dismouting to used repeatedly is difficult damage also, has improved the dismouting efficiency of equipment.
Description
Technical field:
This utility model relates to crane, the steel pipe lower limb docking structure particularly used on a kind of crane.
Background technology:
On road and bridge door machine, many employing flower stand joist steel pipe lower limb structures, the restriction installed due to lifting altitude and transport, the steel pipe lower limb of these road and bridge door machines mostly needs abutting joint, then is connected by bolt group.When engineering project is complete need again to dismount after use on another project building site again, owing to steel pipe lower limb docks, bolt group is by side force, easily cause joint and the deformation of bolt group, and then can not install fast and effectively when causing secondary to use, and need correction or again make, this waste that can cause equipment and the delay of time.
Summary of the invention:
The purpose of this utility model is to design a kind of rational in infrastructure, steel pipe lower limb docking structure of the preferable crane of using effect.
The technical solution of the utility model is, a kind of steel pipe lower limb docking structure of crane, it includes ring flange, bolt, it is characterized in that: be provided with bearing pin in the bottom of upper steel pipe lower limb, be provided with upper flange plate in the bottom of upper steel pipe lower limb, be provided with the pin-and-hole corresponding with bearing pin at the top of lower steel pipe lower limb, it is provided with lower flange on the top of lower steel pipe lower limb, upper and lower ring flange is equipped with bolt.It is provided with support reinforcing plate in the junction of upper and lower ring flange Yu upper and lower steel pipe lower limb.It is fixed with protective cover outside upper and lower ring flange.Described protective cover is that sheet iron is made.
This utility model is rational in infrastructure, using effect good, it is possible to dismount fast and efficiently, and reuse be not easy to damage, improve the dismounting efficiency of equipment.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Specific embodiment of the utility model is:
A kind of steel pipe lower limb docking structure of crane, it includes bolt 3, it is provided with bearing pin 5 in the bottom of upper steel pipe lower limb 1, it is provided with upper flange plate 2 in the bottom of upper steel pipe lower limb, it is provided with the pin-and-hole corresponding with bearing pin at the top of lower steel pipe lower limb 6, it is provided with lower flange 4 on the top of lower steel pipe lower limb, upper and lower ring flange is equipped with bolt；The present embodiment is provided with support reinforcing plate 8 in the junction of upper and lower ring flange Yu upper and lower steel pipe lower limb；The present embodiment is fixed with protective cover 7 outside upper and lower ring flange；Described protective cover is that sheet iron is made, and protective cover can be not only ring flange shading wind and rain, it is to avoid ring flange and bolt generation corrosion, and ring flange dismounting is the most convenient, can service life of effective lifting means；Protective cover is owing to using sheet iron to make simultaneously, there is slight dislocation in the most upper and lower steel pipe lower limb, sheet iron just can clearly reflect, it is simple to user of service and maintainer scent a hidden danger and accident sign in time, it is possible to further ensures the use safety of equipment.
When this utility model is installed, the angle of ring flange is vertical with steel pipe axis, is 78 degree of angles with horizontal line, replaces bolt group to bear side force with bearing pin, it is ensured that flange, bolt group are all not likely to produce deformation, it is possible to being dismounted for multiple times uses.And the junction weldering at ring flange with steel pipe lower limb adds support reinforcing plate, it is possible to further ensure the firm of steel pipe lower limb.
Above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive, and within the protection domain that the obvious change thus extended out or variation are created still in this utility model.
