Abstract
The utility model discloses a grab head of a grab loader, which consists of connecting rods, pin shaft sleeves, a piston and a grab blade. The utility model is characterized in that the connecting rod is sequentially connected with the pin shaft sleeve, the piston, the pin shaft sleeve, the grab blade, the pin shaft sleeve and the connecting rod, each pin shaft sleeve consists of a shaft and a sleeve, the pin shaft sleeves are cylindrical sleeve pipes with the hollow inside and are made of MC casting type nylon, the shafts are in a solid cylindrical shape and are made of No.45 steel, and the grab blade is in a hook shape. Because the pin shaft sleeves adopt the MC casting nylon materials, the materials are hard, have wear resistance and have certain toughness, the service life of the pin shaft sleeves processed by the materials is 2 to 3 times of that of the pin shaft sleeves processed by No.45 steel, and the grab head of the grab loader has the advantages of production cost reduction and maintenance time saving.
Description
Technical field
The utility model relates to a kind of grab loader grappling fixture, is particularly useful for a kind of grab loader grappling fixture that the good pin sleeve of mill property is installed of grab loader in the mine vertical shaft construction.
Background technology
At present, with No. 45 steel processing and fabricatings, this part belongs to consumable accessory to the pin sleeve of the grab loader grappling fixture that uses in the mine construction mostly.No. 45 the steel abrasion resistance is relatively poor, uses a period of time pin sleeve just to need to change.And axle sleeve when wearing and tearing, bearing pin also is worn, and when changing cover, also will change bearing pin, not only delays production, and increases cost of production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, solves the pin sleeve and the bearing pin wear problem of grab loader grappling fixture, and a kind of grab loader grappling fixture that possesses the good pin sleeve of abrasion resistance is provided.
The utility model is that the technical scheme that the technical solution problem is adopted is:
A kind of grab loader grappling fixture, by connecting rod, pin sleeve, piston, grab lobe, its connecting rod successively with pin sleeve, piston, pin sleeve, grab lobe, pin sleeve and connecting rod and be connected.Described pin sleeve is, pin sleeve is made up of axle and cover, and described cover is the sleeve pipe of interior hollow-cylindrical, and its material is the MC monomer cast nylon, and described is solid cylindrical, and material is No. 45 steel, and grabbing lobe is hook-type.Because its material of pin sleeve is designed to the MC monomer cast nylon, the grab loader work reliability that makes has obtained improving greatly, and pin sleeve and bearing pin wear problem have obtained good solution.
The beneficial effects of the utility model are:
Because grab loader grappling fixture pin sleeve has adopted MC monomer cast nylon material, this material not only firmly but also wear-resistingly also have certain toughness, the pin sleeve that uses this materials processing be its application life No. 45 steel processing pin sleeve 2-3 doubly, this grab loader grappling fixture has reduced cost for producing, and has saved maintenance time.
