Abstract
The utility model discloses a case stop device is cuted to stromatolite, include: stand subassembly, square steel tube and bolt, 2 the bottom of individual stand subassembly is fixed respectively and is set up on the box bottom plate of case is cuted to the stromatolite, 2 the top of individual stand subassembly is connected with the square steel tube through the bolt respectively, forms the gate -type frame, can limit the box of case was sheared to the stromatolite vertical motion and plane twist motion effectively to its simple structure, preparation, installation and applied all very convenient.
Description
Technical field
The utility model relates to submarine pipeline seismic resistance field, particularly relates to a kind of lamination and shears case stop means.
Background technology
Native case conventional in shaketalle test roughly has three kinds of forms: rigid box, flexible box and shearing case.Shear case to be usually formed by stacking by 10 ~ 20 layers of steelframe, adjacent two layers can relative sliding, is better than rigid box and flexible box, is considered to ideal model casing in the detrusion of the simulation soil body.
At present, great majority are sheared case and are not adopted stop means, make the vertical movement of casing and plane twisting motion be difficult to control; Minority is sheared case and is then used simple and easy steelframe to be fixed casing, may cause colliding between casing and steelframe friction, effectively cannot ensure the horizontal single-headed motion of casing.Therefore, in actual use, above-mentioned form all has some limitations.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of lamination and shears case stop means, comprises a kind of lamination and shears case stop means, comprising: columns assemblies, square steel tube and bolt; The bottom of two described columns assemblies is fixedly installed on described lamination respectively and shears on the box bottom of case; The top of two described columns assemblies is connected with described square steel tube respectively by described bolt, composition portal frame, is used for limiting vertical movement and the plane twisting motion that described lamination shears case.
Preferably, described columns assemblies comprises round steel pipe and deep groove ball bearing; Described round steel pipe at least equidistantly arranges ten described deep groove ball bearings.
Preferably, be interference fit between described round steel pipe and described deep groove ball bearing, to ensure that described lamination shears the horizontal single-headed motion of case.
By one or more technical scheme of the present utility model, the utility model has following beneficial effect or advantage:
This application provides a kind of lamination and shear case stop means, comprising: columns assemblies, square steel tube and bolt; The bottom of 2 columns assemblies is fixedly installed on lamination respectively and shears on the box bottom of case; The top of 2 columns assemblies is connected with square steel tube respectively by bolt, composition portal frame, effectively can limit vertical movement and plane twisting motion that lamination shears the casing of case, and its simple structure, make, install and apply all very convenient.
Further, this stop means, when being applied to lamination and shearing case, can combinationally use, sliding resistance is very little, and spacing solid and reliable, anti-wear performance is good, the little material of friction factor can be selected if desired to manufacture, to reduce sliding resistance further, meet the requirement of special test.
Accompanying drawing explanation
The structural representation of the lamination shearing case stop means that Fig. 1 provides for the utility model embodiment;
The stereographic map of the lamination shearing case stop means that Fig. 2 provides for the utility model embodiment.
Wherein: 1-lamination shears case, 2-columns assemblies, 3-square steel tube, 4-bolt, 5-round steel pipe, 6-deep groove ball bearing, 7-box bottom.
Embodiment
In order to make the utility model the technical staff in the technical field more clearly understand the utility model, below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described in detail.
See Fig. 1, the lamination that the utility model embodiment provides shears case 1 stop means, comprising: columns assemblies 2, square steel tube 3 and bolt 4.
The bottom of 2 columns assemblies 2 is fixedly installed on lamination respectively and shears on the box bottom 7 of case 1.When fixing, welding can be selected, the mode that to be spirally connected etc. is fixed.
The top of 2 columns assemblies 2 is connected with square steel tube 3 respectively by bolt 4, composition portal frame, is used for limiting vertical movement and the plane twisting motion that lamination shears case 1.
Further, columns assemblies 2 comprises round steel pipe 5 and deep groove ball bearing 6; Round steel pipe 5 at least equidistantly arranges 10 deep groove ball bearings 6.In addition, between round steel pipe 5 and deep groove ball bearing 6, require interference fit, can ensure that lamination shears the horizontal single-headed motion of case 1.
In concrete implementation process, the application selects the lamination be made up of 13 layers of steel frame to shear case 1 and is described.
Casing stop means is made up of columns assemblies 2, square steel tube 3 and bolt 4.
Wherein, columns assemblies 2 is made up of round steel pipe 5 and deep groove ball bearing 6.Before lamination shearing case 1 carries out shaketalle test, first at the first-class pitch arrangement of each round steel pipe 5 13 deep groove ball bearings 6 to form columns assemblies 2, interference fit is required between round steel pipe 5 and deep groove ball bearing 6, then two columns assemblies 2 roots (i.e. bottom) are welded on respectively the relevant position that lamination shears the box bottom 7 of case 1, last columns assemblies 2 top connects to form portal frame by bolt 4 and square steel tube 3.
In process of the test, 13 deep groove ball bearings 6 can ensure that lamination shears the horizontal single-headed motion of case 1, and whole device can limit vertical movement and the plane twisting motion that lamination shears case 1.
By one or more technical scheme of the present utility model, the utility model has following beneficial effect or advantage:
This application provides a kind of lamination and shear case stop means, comprising: columns assemblies, square steel tube and bolt; The bottom of 2 columns assemblies is fixedly installed on lamination respectively and shears on the box bottom of case; The top of 2 columns assemblies is connected with square steel tube respectively by bolt, composition portal frame, effectively can limit vertical movement and plane twisting motion that lamination shears the casing of case, and its simple structure, make, install and apply all very convenient.
Further, this stop means, when being applied to lamination and shearing case, can combinationally use, sliding resistance is very little, and spacing solid and reliable, anti-wear performance is good, the little material of friction factor can be selected if desired to manufacture, to reduce sliding resistance further, meet the requirement of special test.
Although described preferred embodiment of the present utility model, one of ordinary skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the utility model scope.
