More firm in order to support, this bracing or strutting arrangement is two groups.
In order to stablize well dish spring, described lower ball pad is reversed convex type, and described dish spring is enclosed within the protuberance of lower ball pad.
For good firm lower ball pad, 1/3 protuberance of described lower ball pad embeds in pad.
In order to make whole bracing or strutting arrangement more firm, described pad lower end is provided with mount pad.
For pad is more firmly located on mount pad, described pad is arranged on mount pad by screw.
Described lower ball pad is provided with regulating device, described regulating device comprises the bracket suitable with Cylinder Plunger, this bracket below is provided with ball pad, between bracket and upper ball pad, be provided with studs, one end of studs is fixed on bracket, the other end is fixed on ball pad, and in the middle part correspondence of studs, ball pad place is provided with suitable with it nut; The upper end of the lower end of upper ball pad and lower ball pad is suitable.
One end of described studs is threaded connection on bracket, and the other end is threaded connection on upper ball pad.
The corresponding bracket lower end in middle part of described studs is provided with set nut.
The relative prior art of the utility model has the following advantages:
1, upper ball pad of the present utility model and bracket consist of two groups of regulating devices of this mechanism studs, this device and flexible supporting device, stopper head cooperatively interact, flexible support part adopts ball to contact with regulating part, can make this device bear the unbalance loading of any direction on surface level, if upwarping appears in stopper head or under droop a numerical value when larger, slightly rotate and regulate part screw rod to adjust this mechanism height, and then make error in allowed limits.
2, the utility model is simple in structure, easy to operate, and stability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, steel pipe hydrostatic tester Cylinder Plunger bracing or strutting arrangement of the present utility model is described in further detail.
Steel pipe hydrostatic tester Cylinder Plunger bracing or strutting arrangement as shown in Figure 1, this bracing or strutting arrangement is two groups, comprise respectively pad 6 and top thereof with the suitable lower ball pad 4 of Cylinder Plunger, between pad 6 and lower ball pad 4, be provided with dish spring 5; Lower ball pad 4 is provided with screw rod 8, one end of screw rod 8 is fixed on the lower end of lower ball pad 4, the other end is through pad 6, tighten by nut 7 lower end at pad 6, lower ball pad 4 is reversed convex type, and dish spring 5 is enclosed within the protuberance of lower ball pad 4, and 1/3 protuberance of lower ball pad 4 embeds pad 6, pad 6 lower ends and be provided with mount pad 9, pad 6 is arranged on mount pad 9 by screw; Lower ball pad 4 is provided with regulating device, described regulating device comprises the bracket 10 suitable with Cylinder Plunger 12, these bracket 10 belows are provided with ball pad 3, between bracket 10 and upper ball pad 3, be provided with studs 1, one end of studs 1 is fixed on bracket 10, the other end is fixed on ball pad 3, and in the middle part correspondence of studs 1, ball pad 3 places are provided with suitable with it nut 2; The upper end of the lower end of upper ball pad 3 and lower ball pad 4 is suitable; Regulating device is two groups; One end of studs 1 is threaded connection on bracket 10, and the other end is threaded connection on upper ball pad 3; Corresponding bracket 10 lower ends in middle part of studs 1 are provided with set nut 11.
Dish spring 5 is inserted in lower ball pad 4 and is connected to become assembly with pad 6 by screw rod 8 and one group of nut, be installed on two groups of flexible supporting devices that form this mechanism on mount pad 9, this device is connected with follow-up trolley, the necessary pretension of flexible supporting device dish spring 5, and leave certain flying height, and then plunger can be fluctuated in allowed limits.Upper ball pad 3 consists of two groups of regulating devices of this mechanism studs 1 with bracket 10, this device and flexible supporting device, stopper head cooperatively interact, flexible support part adopts ball to contact with regulating part, can make this device bear the unbalance loading of any direction on surface level, if upwarping appears in stopper head or under droop a numerical value when larger, slightly rotating adjusting screw(rod) 8 can adjust this mechanism height, and then makes error in allowed limits.
