The utility model relates to a steel structure ultrasonic testing device, which comprises a handle, a probe device at the lower end of the handle, and a shell with an opening at the lower end; a sealing seat is sliding inside the shell, an installation hole is arranged in the middle of the sealing seat, and a probe is fixed in the installation hole. The upper and lower ends of the probe are projected between the upper and lower ends of the sealing seat and the top wall of the outer shell. Elastic reset parts are provided; water intake holes are arranged on the top wall of the shell, and water intake holes are connected with water supply pipes; water outlets are arranged on the side wall of the shell, and also water outlets are connected with the lower side of the water outlet and probe; when water is not supplied to the outer shell, the sealing seat is located on the upper side of the water outlet and the lower end of the probe is located in the shell, which can effectively avoid wear; when flaw detection is carried out, the water outlet is first outward. Water supply in the shell, under the action of water pressure, the probe is pressed downward to reach the appropriate detection position. At the same time, water flows out of the outlet and forms a water film on the workpiece at the probe, which improves the detection accuracy and reduces the wear of the probe.

一种钢结构超声波检测设备
本技术涉及超声探伤领域,尤其涉及一种钢结构超声波检测设备。
技术介绍
超声波探伤具有不破坏材料结构的特性,因此,其普遍应用于材料领域的探伤检测。由于超声波会受到空气的阻隔干扰,影响了检测准确性。目前,大量的钢结构用超声波检测时,操作者弯腰手持超声波探头对钢结构进行检测,由于钢结构面积大、数量多、探头磨损过大,探头使用寿命降低,增加了探伤检测成本;而且长时间弯腰或下蹲检测容易造成操作者疲劳,劳动强度大、检测速度慢,从而造成检测效率低下。
技术实现思路
本技术所要解决的技术问题是提供一种有效减少探头磨损的钢结构超声波检测设备。为解决上述技术问题,本技术的技术方案是:一种钢结构超声波检测设备,包括手柄,所述手柄的下端设有探头装置,所述探头装置包括下端开口的外壳;所述外壳内滑动设有密封座,所述密封座居中设有安装孔,所述安装孔内固定有探头,所述探头的上下两端均突出于所述密封座的上下端面且所述探头的上端与所述外壳的顶壁之间设置有弹性复位件;所述外壳的顶壁上设有进水孔,所述进水孔连接有供水管;所述外壳的侧壁上设有出水口,还包括出水通道,所述出水通道连通所述出水口和所述探头的下侧;未向所述外壳内供水时,密封座位于所述出水口的上侧且所述探头的下端位于所述外壳内;当向所述外壳内供水时,所述密封座处于所述出水口的下侧。作为优选的技术方案,所述外壳内设有导向套,所述导向套和所述外壳之间设置所述出水通道且所述出水口设置在所述导向套上。作为优选的技术方案,所述导向套的下端相对所述外壳的顶壁的距离小于所述外壳的下端相对所述外壳的顶壁的距离。作为优选的技术方案,所述导向 ...
