Abstract
An inspection ruler for longitudinally welded joints of casings consists of a fixed ruler (1), two positioning supports (2) and a movable ruler (3), wherein the fixed ruler (1) is marked with a cylinder specification, the two positioning supports (2) capable of moving left and right can be locked on the fixed ruler (1), and the movable ruler (3) is marked with scales and with end tips. Besides, the movable ruler (3) is vertically mounted on the fixed ruler (1) and capable of sliding vertically relative to the fixed ruler (1), and the tip of the movable ruler (3) at a zero position and ends of the two positioning supports (2) are positioned on the same circular arc. The inspection ruler is capable of measuring edge angles of longitudinally welded joints of casings with different sizes within a certain specification, and users can read welded joint unfitness and welded joint reinforcement value conveniently and accurately.
Description
Technical field
The utility model relates to the vertical welding joint detection ruler of a kind of housing, is used for the vertical welding joint angularity of measuring vessel housing, unfitness of butt joint, weld reinforcement.
Background technology
Requirement according to GB150-1998 " Steel Pressure Vessels ", after assembling of shell ring longitudinal seam and welding are finished, should check unfitness of butt joint, angularity and the weld reinforcement of vertical welding joint on request, at present, the angularity measuring method of standard recommendation and common way all are to equal 1/6Di (Di is an internal diameter) and be not less than the interior model of 300mm or outer model is measured with chord length.Adopt such measuring method, need not make different inspection templates simultaneously when the diameter of housing, take a lot of work and time-consuming, when the cylindrical shell specification was many, the quantity of model also increased thereupon, brought certain difficulty for the management and the use of model.Measure for vertical welding joint unfitness of butt joint, weld reinforcement, method commonly used at present goes to measure with welding inspection ruler exactly, because measured surface is a circular arc, the location of welding inspection ruler is difficulty relatively, can not measure needed numerical value accurately.
Summary of the invention
The purpose of this utility model provides the vertical welding joint angularity of housing of different size in a kind of energy measurement certain specification scope, and can read the vertical welding joint detection ruler of housing of welding seam misalignment amount and weld reinforcement numerical value easily and accurately.
The technical scheme that realizes above-mentioned purpose is: the vertical welding joint detection ruler of a kind of housing, it can move left and right by a scale that indicates the cylindrical shell specification, two and the positioning supports and a moving chi that indicates scale, head band point that can be locked on the scale form, moving chi is vertically mounted on the scale, and moving chi scale relatively slides up and down, and the chi point when moving the chi zero-bit and the ends of two positioning supports are positioned on the same circular arc.
The utility model has the advantages that: use the housing angularity of different size in detection ruler energy measurement certain specification scope, exempted the worry that the housing of each specification is made a block check model; When checking unfitness of butt joint and weld reinforcement, this detection ruler can accurate in locating, and is convenient, read the numerical value of welding seam misalignment amount and weld reinforcement accurately.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, the vertical welding joint detection ruler of a kind of housing, it can move left and right by a scale that indicates the cylindrical shell specification 1, two and the positioning supports 2 and a moving chi 3 that indicates scale, head band point that can be locked on the scale 1 form, moving chi 3 is vertically mounted on the scale 1, and moving chi 3 scale 1 relatively slides up and down, and the chi point when moving chi 3 zero-bits and the ends of two positioning supports 2 are positioned on the same circular arc.And guarantee that two distances between positioning supports 2 ends equal 1/6Di, and greater than 300mm.
Principle of work of the present utility model is as follows:
When measuring the vertical welding joint angularity of housing with this detection ruler, the housing specification that earlier two positioning supports 2 is adjusted to scale 1 demarcation is consistent with measured housing specification, with the detection ruler standing upright, check that two positioning supports 2 of chi prop up the housing of weld seam both sides, the tip position of moving chi 3 is near a side weld, the axis of checking chi is vertical with the housing longitudinal seam, the moving chi 3 that slides makes the housing of needle point contact weld seam either side, reading on the at this moment moving chi 3 is the angularity of the vertical welding joint of this place's housing, move the position of checking chi, measure the difference angularity, the greatest measure that draws is the angularity of the vertical welding joint of this housing.Adopt same measuring method, move and check chi, measure the numerical value of longitudinal seam both sides mother metal respectively, the difference of both sides numerical value is the unfitness of butt joint at this place; Measure the numerical value of longitudinal seam highest point and the numerical value of weld seam either side mother metal respectively, the difference of two numerical value is the reinforcement of this place's weld seam.
Claims (1)
1. vertical welding joint detection ruler of housing, it is characterized in that: it can move left and right by a scale (1) that indicates the cylindrical shell specification, two and the positioning supports (2) and a moving chi (3) that indicates scale, head band point that can be locked on the scale (1) form, moving chi (3) is vertically mounted on the scale (1), and moving chi (3) scale (1) relatively slides up and down, and the chi point when moving chi (3) zero-bit and the ends of two positioning supports (2) are positioned on the same circular arc.
