Further, the inboard hook groove of hook portion is an arc groove on the described side plate upper bracket, and the inside and outside two sides of the gib head of hook portion are arc under the described hook plate down.

The inboard hook groove of hook portion and the radius of curvature of the inside and outside two sides of the gib head of hook portion and the corresponding coupling of cannelure of the upper and lower end face of bearing pin connector under the hook plate down on the described side plate upper bracket.

Again, the inboard hook groove of hook portion leans on the radius of curvature of tailgate direction one side inwall and the corresponding coupling of arcwall face in the bearing pin connector outside on the described side plate upper bracket.

The outer face of described side plate lower carriage is an arc.

The corresponding coupling of arcwall face in the radius of curvature of described side plate lower carriage outer face and the bearing pin connector outside.

Oil cylinder is implemented can give the outside thrust of oil cylinder seat of pulling pin when pulling pin owing to pull pin, and this oil cylinder seat of pulling pin hooks the bearing pin connector by upper and lower two places, thereby becomes effective support that the cylinder action of pulling pin is implemented.

The beneficial effects of the utility model:

The oil cylinder seat of pulling pin that the utility model is designed has the design of lordosis hook, realize location and support by the cannelure of being opened on the end face that hooks column type bearing pin connector, and can in groove, slide, change the position for the oil cylinder of pulling pin quickly and easily, thereby realize pulling out and installing diverse location place bearing pin on the same anchor ring.Have simple in structurely, easy to operate, can effectively improve the efficient of pulling out and installing of bearing pin.

The specific embodiment

Referring to Fig. 1～Fig. 5, the utility model oil cylinder seat structure of pulling pin is used for the link pins shaft coupling piece 7 and the oil cylinder 8 of pulling pin; Comprise, prop up seat board 1, be used for fixing the afterbody of the oil cylinder 8 of pulling pin; Two blocks of side plates 2,2 ', be connected to the both sides of a seat board 1, side plate 2,2 ' comprises fixed part 21,21 ' and stretch out from the both sides of fixed part 21,21 ' one end and to form upper bracket 22,22 ', lower carriage 23,23 ', upper bracket 22,22 ' end are hook-shape structure, has a hook groove, hook portion in the formation; Lower carriage 23 (is example with lower carriage 23) has two pin-and-holes 231,232 along its length; Two following hook plates 3,3 ', the one end is a hook-type, forms hook portion down, is connected in two blocks of side plates 2,2 ' lower carriage pin-and-hole 231,232 by two

bearing pins

4,4 ', 5,5 ' respectively, and is corresponding with the last hook portion of upper bracket; Tailgate 6 is connected in seat board 1 outboard end, connects seat board 1 and two blocks of side plates 2,2 '.

Referring to Fig. 4 a, Fig. 9, the inboard hook groove 221 of hook portion is an arc groove on the described side plate upper bracket 22, and the described inside and outside two sides 311,312 of the gib head 31 of 3 times hook portions of hook plate down are arc.
