Description
the
【技术领域】【Technical field】
本发明涉及机械构造领域,尤其涉及一种焊补装置。 The invention relates to the field of mechanical structures, in particular to a welding repair device.
【背景技术】【Background technique】
随着一些容器、管道运行时间的持续增长,材质老化日趋严重,其表面产生裂缝或砂眼后,成喷射状泄漏,由于容器内的压力,直接用电焊焊补是达不到目的的,泄漏量只会越补越大。目前对于气、液容器的表面砂眼、裂缝等的封补抢修,一个是采用停输介质,进行捻压或加入塞具阻止其渗漏,再加入弧板焊接或卡具,达到堵漏的目的。另一种方法如图七所示,主要由固定支架8和压紧螺钉1组成,压紧螺钉1的前端设有连接帽3并与压紧垫块4连接为一体,在压紧垫块4下面设有密封垫片5。通常泄漏是由于腐蚀、开裂、受力变形等原因造成,所以此种办法的堵压密封效果一般很难奏效。即使该方法勉强可行,却不是长久之计,最终还是要进行二次作业,在停输介质后再进行焊补作业,未能一次性解决问题。现有的堵漏方法虽然可行,但是容易造成机械设备的损坏,另一方面该种方法及不安全,如果压力有所变动动,塞具将有可能受力弹出,造成恶性事故的发生。 With the continuous increase of the running time of some containers and pipelines, the aging of the material is becoming more and more serious. After cracks or sand holes appear on the surface, they leak in a spray shape. Due to the pressure in the container, it is impossible to directly repair the purpose by electric welding. It will only get bigger and bigger. At present, for the sealing and emergency repair of trachoma and cracks on the surface of gas and liquid containers, one is to use the stop medium, twist and press or add plugs to prevent leakage, and then add arc plate welding or fixtures to achieve the purpose of plugging . Another method, as shown in Figure 7, is mainly composed of a fixing bracket 8 and a compression screw 1. The front end of the compression screw 1 is provided with a connecting cap 3 and is connected with the compression pad 4 as a whole. A sealing gasket 5 is provided below. Usually leakage is caused by reasons such as corrosion, cracking, stress deformation, etc., so the sealing effect of this method is generally difficult to be effective. Even if this method is barely feasible, it is not a long-term solution. In the end, a secondary operation is required, and the welding repair operation is performed after the medium is stopped, which fails to solve the problem once. Although the existing plugging method is feasible, it is easy to cause damage to mechanical equipment. On the other hand, this method is not safe. If the pressure fluctuates, the plug may be ejected by force, resulting in a vicious accident.

【具体实施方式】【Detailed ways】
参见附图,本发明采用了一种焊补装置,其特征在于:包括成型罩、夹套、带柄钢球和石棉环条;夹套为三臂弹性夹具,其圆形口直径略大于成型罩圆形上开口,成型罩底部有方形槽,可放置石棉环条。 Referring to the accompanying drawings, the present invention adopts a welding repair device, which is characterized in that it includes a forming cover, a jacket, a handle steel ball and an asbestos ring strip; the jacket is a three-arm elastic clamp, and the diameter of its circular opening is slightly larger than that of the forming The upper opening of the cover is circular, and there is a square groove at the bottom of the forming cover, which can place asbestos ring strips.
进一步的,带柄钢球可以为硬质橡胶材料的圆球。 Further, the steel ball with a handle can be a hard rubber ball.
进一步的,焊补前,将夹套三条夹臂从成型罩圆形上开口缩形伸入,再将带柄钢球从成型罩方形下开口置入夹套三条夹臂中间,可以成悬空夹紧状态,并将石棉环条均匀的嵌于成型罩的底部方形槽中。 Further, before the welding repair, the three clamping arms of the jacket are retracted and extended from the circular upper opening of the forming cover, and then the steel ball with a handle is inserted into the middle of the three clamping arms of the jacket from the square lower opening of the forming cover to form a suspended clamp. Tight state, and evenly embed the asbestos ring strips in the square groove at the bottom of the forming cover.
进一步的,焊补后,用硬物推动带柄钢球,并将夹套从成型罩中拔出,此时沿成型罩圆形上开口方向拉钢球柄,直至受压封闭。 Further, after welding repair, push the steel ball with handle with a hard object, and pull out the jacket from the forming cover. At this time, pull the steel ball handle along the direction of the circular upper opening of the forming cover until it is closed under pressure.
具体焊补步骤: Specific welding repair steps:
步骤1:将夹套连同夹套内的带柄钢球预先置于成型罩内。夹套为三臂弹性夹具,其圆形口直径略大于成型罩圆形上开口,夹套三条夹臂从成型罩圆形上开口缩形伸入,再将带柄钢球从成型罩方形下开口置入夹套三条夹臂中间,成悬空夹紧状态。 Step 1: Place the jacket and the steel ball with handle inside the jacket in the forming cover in advance. The jacket is a three-arm elastic clamp. The diameter of its circular mouth is slightly larger than the circular upper opening of the forming cover. The three clamping arms of the jacket are stretched from the circular upper opening of the forming cover. The opening is placed in the middle of the three clamping arms of the jacket to form a suspended clamping state.
步骤2:将石棉环条(用石棉成分条的目的是防止在后序焊接时的高温损坏)均匀的嵌于成型罩的底部方形槽中。劲量以容器壁泄漏处为中心,稍用微力(石棉条与容器壁达到不渗水)达到贴于容器壁,原漏于容器壁表面的液体通过石棉条的密封后进入成型罩,泄漏介质从裂缝或砂眼喷出后形成扩容,对成型罩底边与容器壁之间的焊接难度降低。 Step 2: Insert asbestos ring strips (the purpose of using asbestos component strips is to prevent high temperature damage during subsequent welding) evenly in the bottom square groove of the forming cover. The energy is centered on the leaking part of the container wall, and it sticks to the container wall with a little force (the asbestos strip and the container wall are impervious to water). Cracks or sand holes are ejected to form expansion, which reduces the difficulty of welding between the bottom edge of the forming cover and the container wall.
步骤3:此时成型罩底边与容器壁之间已无压力,可以对其进行焊接(打包满焊)作业。焊接过程中,泄漏介质沿带柄钢球周围通过成型罩圆形上开口流出,由于上开口直径远远大于泄漏点,所以不但压力降低,而且排放流量增大,可以完全排除安全隐患。 Step 3: At this time, there is no pressure between the bottom edge of the forming cover and the container wall, and welding (full packing and welding) can be performed on it. During the welding process, the leakage medium flows out through the circular upper opening of the forming cover along the circumference of the handle steel ball. Since the diameter of the upper opening is much larger than the leakage point, not only the pressure is reduced, but also the discharge flow is increased, which can completely eliminate potential safety hazards.
步骤4:成型罩底边与容器壁之间满焊接完毕后,用硬物将带柄钢球向下推出夹套,并将夹套从成型罩中拔出,此时沿成型罩圆形上开口方向拉钢球柄,直至受压封闭。 Step 4: After the full welding between the bottom edge of the forming cover and the container wall is completed, use a hard object to push the steel ball with handle downwards into the jacket, and pull the jacket out of the forming cover. Pull the steel ball handle in the opening direction until it is closed under pressure.
步骤5:以满焊形式将成型罩上口打包焊死。 Step 5: Pack and weld the upper part of the forming cover in the form of full welding.
