Abstract
The utility model relates to a slider suitable for crane telescopic boom, including friction section and with external section perpendicular of setting up of friction section, friction section with external section integrated into one piece, friction section be the arc, and a friction section upper surface is equipped with the oil groove that two intersections are the X type, and the oil filler point is located the nodical of two cross oil groove to be located, external section under the narrow width is provided with the bolt hole that supplies hexagon socket head cap screw to pass in the external section, fixes on hanging the wall through soket head cap screw. The utility model has the advantages of 1, curved surface nylon sliding block docks into the U type, increases davit and slider contact surface, and stress concentration when reducing the atress has improved the intensity that the polygon stretches out and draws back the arm, and simultaneous processing single piece cost is lower. 2, groove design has the self -lubricating function.
Description
Technical field
The utility model is related to a kind of slide block, more particularly to a kind of slide block suitable for telescopic crane boom.
Background technology
Need to arrange nylon slide block between each joint arm of box type telescopic boom crane, to support and keep each section telescopic arm
Between relative slip.In existing technology, the front lower slider designs between each joint arm of General polygon meshes telescopic arm are into pros
Shape structure, the contact area very little between the slide block of this square structure and each joint arm, so as to cause telescopic arm and shoe contact
Position stress concentration phenomenon.
Utility model content
Technical problem to be solved in the utility model is：A kind of slide block suitable for telescopic crane boom is provided, to solve
Certainly above-mentioned technical problem.
The utility model is by solving the problems, such as the technical scheme for adopting set forth above：
A kind of slide block suitable for telescopic crane boom, including friction section 1 and vertically disposed with friction section 1 external section 2,
The friction section 1 is integrally formed with described external section 2, and the friction section 1 is arc, and the upper surface of friction section 1 is provided with two
Intersect the oil groove 3 in X-type, oil filler point 4 is located at the point of intersection of two crossed oil grooveses 3, described external section 2 up-narrow and down-wide, external section 2
On be provided with the bolt hole 5 passed through for hexagon socket head cap screw, be fixed on by soket head cap screw and hung on wall.
The lower end of described external section 2 is cambered outwards arc.
Thickness of external section of described 2 thickness more than friction section 1.
The thickness at the described middle part of friction section 1 is equal with the thickness at the two ends of friction section 1.
Described friction section 1 is change wall thickness friction section.
Described friction section 1 is less than the thickness of the other end away from the thickness of described external section 2 one end.
Described two intersect the oil duct 6 at the maximum spacing of the oil groove 3 in X-type with two oil grooves of linking.
The material of described slide block is high-strength nylon.
Described bolt hole 5 is counterbore, and the depth at the step of counterbore away from upper surface is slightly less than the thickness of nut.
Described bolt hole 5 is special-shaped through hole, and the special-shaped through hole cross section is middle isosceles trapezoid, two ends it is semicircle and
Two ends semicircle is convenient to fix respectively with upper and lower two base of isosceles trapezoid as diameter.
The beneficial effects of the utility model are：1st, the multiple slide block monomers of multiple blades, curved surface nylon are circumferentially arranged with
Slide block is butted into U-shaped, increases arm and slider contact surface, and stress concentration when reducing stress improves the strong of polygon telescopic arm
Degree, while it is relatively low to process cost per unit.2nd, trench design has self-lubricating function.
