Abstract
The utility model discloses a parallels structure during concatenation of main chord tube of crane arm frame, comprises a base, the one end of base is equipped with the limiting plate, be equipped with the (gate)wedge on the base, sliding fit has the slider on the (gate)wedge, the middle part of its (gate)wedge is equipped with inside sunken recess, be equipped with the guide rail on the (gate)wedge up end of recess both sides, the bottom middle part of slider is equipped with and cooperates the bead with the guide slot, the middle part of bead is equipped with transfers knothole, adjusting bolt has been closed among the accent knothole soon, adjusting bolt's an other end rotation closes on the limiting plate of one end, be equipped with on the terminal surface under the slider of bead both sides with guide rail complex guide slot, the up end of slider is equipped with the skid resistant course. The utility model discloses satisfied main chord tube when installation required precision than higher requirement, stability is good, and its adjusting range is big in addition, requirement in the time of can satisfying the concatenation of multiple main chord tube, and application range is wide, through the structural design of slider up end skid resistant course to increase the frictional force between main chord tube and the slider, messenger's equipment is more stable.
Description
Technical field：
This utility model is related to crane frock clamp field, relates generally to during a kind of crane arm support main chord tube splicing
Parallels structure.
Background technology：
Arm support group pipe refers to carry out spelling the operation that point connects by the body of arm support main chord tube and two end connectors, is whole arm support
1st procedure of manufacturing process flow, is also the basis that arm support group fans operation.Often 4 main chord tubes in section jib structure
It is main stress part in hoisting operation, spell point precision and welding quality is very big to the rigidity of arm support and intensity effect.In the past
In production model, have been used up old-fashioned polylith tabular parallels and be overlapped, in splicing, adjustment is loaded down with trivial details, be difficult to meet
Adjustment accuracy and use requirement that equipment is installed, and in splicing rotation process, moving easily occurs in general parallels, stable
Property poor, thus affect install.
Utility model content：
This utility model purpose is exactly the defect in order to make up prior art, provides a kind of crane arm support main chord tube splicing
When parallels structure.
This utility model is achieved through the following technical solutions：
A kind of parallels structure during crane arm support main chord tube splicing, includes base, one end of described base is provided with limit
Position plate, described base is provided with wedge, described wedge is sliding combined with slide block it is characterised in that：The middle part of described wedge sets
Have a groove caving inward, the wedge upper surface of described groove both sides is provided with guide rail, the center bottom of described slide block be provided with
Guide groove coordinates fin, and the middle part of described fin is provided with adjustment hole, is combined with adjustment bolt in described adjustment hole, described adjustment bolt
Other end screw on limiting plate at one end, the slide block lower surface of described fin both sides is provided with and the leading of guide rail cooperation
Groove, the upper surface of described slide block is provided with skid resistant course.
The utility model has the advantages that：
This utility model is adjusted by bolt and fixes the demand with the relative motion of slide block to meet height for the wedge, mistake
Journey middle guide and guide groove play the effect of positioning and guiding reinforcing it is ensured that the stability of wedge and slide block, when meeting main chord tube and installing
The higher requirement of required precision, good stability, and also its adjusting range is big, requires, make when can meet multiple main chord tube splicing
Wide with scope, by the structure design of upper end of slide block face skid resistant course, thus increasing the frictional force between main chord tube and slide block, make to set
Standby more stable.
Brief description：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
Referring to accompanying drawing.
Parallels structure during a kind of splicing of crane arm support main chord tube, includes base 1, and one end of base 1 is provided with spacing
Plate 2, base 1 is provided with wedge 3, and wedge 3 is sliding combined with slide block 4, and the middle part of wedge 3 is provided with the groove 5 caving inward, recessed
The wedge upper surface of groove 5 both sides is provided with guide rail 6, and the center bottom of slide block 4 is provided with and coordinates fin 7, the middle part of fin 7 with guide groove
It is provided with adjustment hole, be combined with adjustment bolt 8 in adjustment hole, the other end of adjustment bolt 8 screws on limiting plate 2 at one end,
The slide block lower surface of fin 7 both sides is provided with the guide groove with guide rail cooperation, and the upper surface of slide block 4 is provided with skid resistant course 9.
