The specific embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the partial enlarged drawing among Fig. 1.Adjustable piston ring of the present utility model comprises circular piston ring group 3, mainly by a plurality of end to end gripper shoe 31 dismountable connecting to form, connects by rotatable guiding mechanism 32 between adjacent two gripper shoes 31.So the quantity of the gripper shoe 31 of installing in the piston ring group 3 can determine according to actual needs that the radian between adjacent two gripper shoes 31 can be regulated.
This piston ring group 3 is divided into two-layer up and down, and two-layer structure is identical, and this gripper shoe 31 Yi Bian be minor face, can be designed to the shape of the isosceles trapezoid that is similar to fillet as shown in the figure on one side for long limit.Fixedly connected by modes such as bolt 34 and nuts 35 in long limit with adjacent two gripper shoe 31 of layer, minor face is by rotatable guiding mechanism 32 connections.This bolt 34, nut 35 and guiding mechanism 32 are connected and fixed bilevel gripper shoe 31 simultaneously.The bolt 34 outer supporting sleeves 33 that are with are with the distance between two-layer about fixing.
Fig. 3 be the A-A of Fig. 2 to cutaway view, as shown in the figure, guiding mechanism 32 two ends are stud 321, are used for gripper shoe 31 fixing.Stud 321 respectively is welded with a double-screw bolt up and down to 322, and this double-screw bolt comprises left double-screw bolt and right double-screw bolt to 322, be welded on respectively on the correspondence position of two studs 321, and vertical with stud 321.
Be equipped with in the middle of the left and right sides double-screw bolt can left rotation and right rotation adjustment cover 323, assemble the back and guarantee that left and right sides double-screw bolt is isometric.When needs are adjusted the piston ring radian, adjust cover 323 rotation simultaneously for two up and down, make the 321 parallel indentations simultaneously of two studs to reach the adjustment purpose.Be to save cost consideration, one in two studs 321 also can be adopted bolster to replace, and this bolster is fixed with gripper shoe 31 by pad and split pin.
Be provided with one or more jack 1 in the middle of the piston ring group 3, the quantity of setting determines that according to the diameter of storage tank the two ends of jack 1 link to each other with piston ring group 3 by jack pad assembly 2.Fig. 4 is the structural representation of jack pad assembly 2, and support seat board 21 1 sides of jack pad assembly 2 link to each other with gripper shoe 31, welding supporting seat 22 on the opposite side.As shown in the figure, support seat board 21 and be the trapezoidal shape of approximate right angle with engage 31, its hypotenuse and gripper shoe 31 link to each other by screw bolt and nut, weld fixed supporting seat 22 on its right-angle side.This supporting seat 22 is a rectangular slab, and jack 1 is fixed on this supporting seat 22.
Adjustable piston ring of the present utility model, be combined into by a plurality of gripper shoes, highly be 200m, length can be determined according to the diameter of storage tank, adopt governor motion to regulate radian between the gripper shoe, large-scale storage tank can satisfy the above storage tank construction of 2m diameter and use according to the specification of the wallboard Thickness Design piston ring of storage tank with piston ring.The utility model is a kind of general utility tool, and one-time investment can use when making the storage tank of multiple different size, and is quick and easy, save time and save money, and reached beneficial technical effects.
