技术领域 technical field
本实用新型涉及一种塑料检查井焊接强度试验装置，属于产品性能检测与试验领域。 The utility model relates to a welding strength testing device for a plastic inspection well, which belongs to the field of product performance testing and testing.
背景技术 Background technique
检查井，俗称“窖井”，是在地下管线位置上每隔一定距离修建的竖井，是城市道路地下基础设施之一，主要供检修管道、清除污泥及用以连接不同方向、不同高度管线使用的构筑物。大部分设在转弯处、管道交汇处、管径或坡度改变处、跌水处以及直线管段上。塑料检查井由于具有密封性好，可全天候施工，不受天气制约，可分体组合，能上下调节高度，排水性能优异，施工方便，重量轻，易于运输，施工周期短，综合造价低，维护费用少等优点，而逐步取代了传统的砖砌结构或钢筋混泥土结构的检查井。塑料检查井在生产过程中通常需要对接焊，所以会产生焊接熔缝，但受材料性能、焊接温度、操作水平等因素的影响，焊缝往往会有虚焊、假焊、焊不透等现象，为保证塑料检查井的整体强度，也即保证焊缝的强度，必须对焊缝强度进行检测。而由于缺乏塑料检查井焊接强度专用检测装置，现有塑料检查井的焊接强度检测大多采用传统的机械拉伸式检测试验装置完成，其结构复杂，操作繁琐，可靠性差。为解决这一问题而必须设计一种塑料检查井焊接焊缝强度试验检测的专用装置。 Inspection wells, commonly known as "cellar wells", are shafts built at intervals of underground pipelines. They are one of the underground infrastructures of urban roads. They are mainly used for maintenance of pipelines, removal of sludge, and connection of pipelines in different directions and heights. structures used. Most of them are located at bends, pipe junctions, pipe diameter or slope changes, water drops, and straight pipe sections. Due to its good sealing performance, the plastic inspection well can be constructed around the clock without being restricted by the weather. It can be combined separately, and the height can be adjusted up and down. With the advantages of low cost and other advantages, it gradually replaced the inspection well of the traditional brick structure or reinforced concrete structure. Butt welding is usually required in the production process of plastic inspection wells, so welding seams will be produced. However, affected by factors such as material properties, welding temperature, and operating level, the welds often have virtual welding, false welding, and impenetrable welding. , in order to ensure the overall strength of the plastic inspection well, that is, to ensure the strength of the weld, the strength of the weld must be tested. However, due to the lack of special detection devices for the welding strength of plastic inspection wells, the welding strength detection of existing plastic inspection wells is mostly completed by traditional mechanical tensile testing devices, which have complex structures, cumbersome operations, and poor reliability. In order to solve this problem, it is necessary to design a special device for testing and detecting the strength of plastic inspection well welding seam.
实用新型内容 Utility model content
本实用新型的目的是提供一种水压式塑料检查井焊接强度专用试验装置及检测方法，完成塑料检查井焊接焊缝强度的试验检测，以克服传统塑料检查井焊接强度检测装置的结构复杂、操作繁琐的缺点和不足。 The purpose of this utility model is to provide a hydraulic type plastic inspection well welding strength special test device and detection method to complete the test and detection of the welding seam strength of the plastic inspection well, so as to overcome the complicated structure of the traditional plastic inspection well welding strength detection device. The shortcomings and shortcomings of cumbersome operation.
本实用新型按以下技术方案实现：一种塑料检查井焊接强度试验装置，包括机架1、工作台2、密封圈3、塑料检查井5、锁紧抱箍7；机架1通过地脚螺栓固定在地基上，工作台2通过螺栓安装在机架1上，密封圈3安装在工作台2上，工作台2上开设有注水孔4，塑料检查井5通过锁紧抱箍7安装在工作台2上部，塑料检查井5筒体连接处设有焊缝6。 The utility model is realized according to the following technical scheme: a plastic inspection well welding strength test device, including a frame 1, a workbench 2, a sealing ring 3, a plastic inspection well 5, and a locking hoop 7; the frame 1 passes through the anchor bolts Fixed on the foundation, the workbench 2 is installed on the frame 1 through bolts, the sealing ring 3 is installed on the workbench 2, the workbench 2 is provided with a water injection hole 4, and the plastic inspection well 5 is installed on the workbench through the locking hoop 7. On the upper part of the platform 2, a weld 6 is provided at the joint of the plastic inspection well 5 cylinder.
塑料检查井焊接强度试验装置检测方法，先将制作好的塑料检查井5井口朝下安置于工作台2上，用锁紧抱箍7将塑料检查井5锁紧固定在工作台2上，以保证井口可靠密封且加压时不脱落，再通过工作台2上开设的注水孔4向塑料检查井5内注满压力水至给定压强，保压至给定时间，观察塑料检查井5筒体连接焊缝6处是否出现裂纹、断裂、损坏、变形，从而达到对塑料检查井5焊缝强度的试验检测。 The detection method of the plastic inspection well welding strength test device is to first place the prepared plastic inspection well 5 on the workbench 2 with the wellhead facing down, and lock and fix the plastic inspection well 5 on the workbench 2 with the locking hoop 7, so that Ensure that the wellhead is reliably sealed and does not fall off when pressurized, and then fill the plastic inspection well 5 with pressurized water through the water injection hole 4 on the workbench 2 to a given pressure, keep the pressure for a given time, and observe the plastic inspection well 5 Whether there are cracks, fractures, damages, or deformations at the welding seam 6 of the body connection, so as to achieve the test and detection of the strength of the welding seam of the plastic inspection well 5.
一种塑料检查井焊接强度试验装置的工作原理为：当塑料检查井5内注满高压水后，高压水作用于塑料检查井5筒壁四周，作用于井筒壁径向的水压作用力互相平衡抵消，但会使筒臌胀。作用于井筒壁顶部的水压作用力，方向垂直向上，使井筒有轴向向上拉伸的趋势，而井筒体下部通过锁紧抱箍7与工作台2固结，作用于井筒壁下部工作台2上的水压作用力，方向垂直向下，使井筒有轴向向下拉伸的趋势，从而使塑料检查井5筒体受到了轴向向上和向下的作用力，这对力使塑料检查井5产生轴向拉力，焊缝6处为轴向受拉力的薄弱处，首先受破坏的应该是塑料检查井5的焊缝6处。因此，高压注水加压达到了焊缝强度试验检测的目的。 The working principle of a plastic inspection well welding strength test device is as follows: when the plastic inspection well 5 is filled with high-pressure water, the high-pressure water acts on the surrounding walls of the plastic inspection well 5, and the hydraulic forces acting on the radial direction of the well bore wall interact with each other. The balance cancels out, but makes the barrel swell. The hydraulic force acting on the top of the wellbore wall is vertically upward, making the wellbore have a tendency to stretch upward in the axial direction, and the lower part of the wellbore body is consolidated with the workbench 2 through the locking hoop 7, acting on the workbench at the lower part of the wellbore wall The force of water pressure on 2, the direction is vertically downward, makes the wellbore have a tendency to stretch downward axially, so that the cylinder of the plastic inspection well 5 is subjected to axially upward and downward forces, which make the plastic The inspection well 5 produces axial tension, and the weld 6 is the weak point under the axial tension, and the weld 6 of the plastic inspection well 5 should be damaged first. Therefore, high-pressure water injection pressurization achieves the purpose of weld strength test detection.
