Abstract

The utility model discloses a clamp tool of a loader. An upper clamp body is hinged to a lower clamp body through a hinge-joint hinge pin, an oil cylinder is connected with the upper clamp body through an oil cylinder hinge pin, a shaft sleeve is connected with the lower clamp body through a shaft sleeve hinge pin, a fixing lug base on the inner side of the upper clamp body is connected with the shaft sleeve through a fixing pull rod, and the fixing lug base is fixed through a fixing pull rod hinge pin. The clamp tool has the advantages that the structural strength of the upper clamp body can be effectively enhanced through the fixing pull rod, meanwhile, the area of contact between the upper clamp body and wood is increased, the clamping force is increased, damage influences on the upper clamp body caused by the wood in operation are reduced, and the good effect for improving the structural strength, the complete-machine stability and the operation efficiency of the clamp is achieved.

Description

Loader clamp facility
Technical field
The utility model relates to a kind of clamp facility, especially the cylindrical facility of loader clamp.
Background technology
As everyone knows, loader clamp facility are widely used for the cylindrical materials such as handling and clamp timber, oil pipe, clamp facility are mainly made up of hinged upper clamp, lower clamp and oil cylinder, take handling timber as example, current loader clamp facility in the time of clamp operation and the contact area of timber generally all less, clamping force is inadequate, causes operation steady not; While, because timber is long, is difficult for capturing its center, and can produce an angle of inclination between caliper, also there will be the not steady phenomenon of caliper center of gravity imbalance, operation, particularly evident in the time of pavement roughness.Above situation all can cause timber to produce a larger instant impact to upper clamp, goes down for a long time and can make upper clamp fatigue deformation, reduces the structural strength of caliper, shortens the application life of clamp.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, operation is steady, reliability is high and can extend the clamp loader clamp facility in application life.
The purpose of this utility model is achieved in that upper clamp is hinged by hinging pin shaft and lower clamp, oil cylinder is connected with upper clamp by oil cylinder bearing pin, axle sleeve is connected with lower clamp by axle sleeve bearing pin, the fixed ear base of upper clamp inner side is connected with axle sleeve by steady brace, and fixes with steady brace bearing pin.
The beneficial effects of the utility model are: the structural strength that can effectively strengthen upper clamp by steady brace, increased the contact area of upper clamp and timber simultaneously, while reducing operation, because of the damage influence of timber reason to upper clamp, the structural strength, complete machine stability, the operating efficiency that improve clamp are had to good effect.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model embodiment.
1 upper clamp, 2 fixed ear bases, 3 lower clamps, 4 steady brace bearing pins, 5 steady braces, 6 hinging pin shafts, 7 axle sleeves, 8 axle sleeve bearing pins, 9 oil cylinder bearing pins, 10 oil cylinders in figure.
The specific embodiment
Embodiment: these clamp facility comprise upper clamp 1, fixed ear base 2, lower clamp 3, steady brace bearing pin 4, steady brace 5, hinging pin shaft 6, axle sleeve 7, axle sleeve bearing pin 8, oil cylinder bearing pin 9, oil cylinder 10, upper clamp 1 is hinged by hinging pin shaft 6 and lower clamp 3, a pair of oil cylinder 10 is connected with upper clamp 1 by oil cylinder bearing pin 9, upper clamp 1 is rotated around hinging pin shaft 6 axis under oil cylinder 10 effects, the interior plate of left and right upper clamp 1 respectively has a fixed ear base 2, above lower clamp 3, also there are two axle sleeves 7 simultaneously, be connected with lower clamp 3 by axle sleeve bearing pin 8, and also can rotate around axle sleeve bearing pin 8, the fixed ear base 2 of upper clamp 1 is connected with axle sleeve 7 by steady brace 5, and fixing with steady brace bearing pin 4, can be simultaneously along with the motion of upper clamp 1 rotates around axle sleeve bearing pin 8, simultaneously the lower end curved surface of steady brace 5 self flushes with the lower end curved surface of upper clamp 1.Can effectively strengthen the structural strength of upper clamp 1 by steady brace 5, increased the contact area of upper clamp 1 with timber simultaneously, while reducing operation, because of the damage influence of timber reason to upper clamp, the structural strength, complete machine stability, the operating efficiency that improve clamp are had to good economic benefit.

Claims (1)
