Abstract

The invention provides a continuous vacuum weld joint detector for a bottom plate of a large-sized storage tank. The continuous vacuum weld joint detector for the bottom plate of the large-sized storage tank is characterized by being provided with a display, a camera, a micro vacuum pump, a steering wheel, a load-bearing wheel, a clapboard and a soap water brush. According to the technical scheme, soap water can be automatically filled into a weld joint during vacuum weld joint detection work, and detection personnel can push the continuous vacuum weld joint detector of which the vacuum degree is over -40KPa for the bottom plate of the large-sized storage tank slowly along the weld joint to perform vacuum detection. Due to the adoption of the technical scheme, the problem of incapability of continuously detecting existing in an ordinary vacuum weld joint detector is solved; the continuous vacuum weld joint detector plays positive roles in lowering the weld joint detection working strength of the bottom plate of the large-sized storage tank and increasing the detection efficiency.

Description

Continous way large-scale storage tank base plate weld joint vacuum detector

Technical field

The present invention relates to a kind of steel plate butt-weld vacuum detection instrument, especially a kind of continous way large-scale storage tank base plate weld joint vacuum detector.

Background technology

Be close on the ground because the large-scale storage tank base plate has one side, make the base plate butt-weld can only carry out single-sided welding, and the more two-sided welding quality of weld seam single-sided welding quality be poor, therefore extremely important to the detection of large-scale storage tank base plate weldquality.Yet kerosene detection, full water test, inflation leak test etc. are commonly used simple and effective detection method for quality of welding line, are not suitable for the detection of large-scale storage tank base plate weld seam.

Therefore, large-scale storage tank base plate weldquality local vacuum-pumping detection method has appearred in prior art: at large-scale storage tank base plate face of weld position brushing suds, with weld seam inspection vacuum measuring tank cover,, in weld seam inspection vacuum detecting case, vacuumize, observe vacuum detecting case inside weld surface and whether produce bubble, thereby determine whether weld seam has leakage point.

All various weld joint vacuum detection cases in the prior art are batch (-type) and detect mode of operation: be coated with suds → vacuumize → observe adopt → emptying, and then repeat: adopt → emptying of painting suds → vacuumize → observe.Adopt the weld joint vacuum detection case of this batch operation mode to be detected large-scale storage tank base plate weldquality, its working strength is large, efficiency is low.

Summary of the invention

Purpose of the present invention: be for the problems referred to above of existing background technology, proposed a kind of continous way large-scale storage tank base plate weld joint vacuum detector.

The present invention is achieved in that a kind of continous way large-scale storage tank base plate weld joint vacuum detector, display, video line, camera, vacuum meter, minipump, housing, transparent plexiglass plate, dividing plate, stopper, sealing strip, deflecting roller, BOGEY WHEEL, pushing hands handle, suds brush etc., consists of; It is characterized in that: transparent plexiglass plate sticks on housing, camera, vacuum meter, minipump, stopper are arranged on transparent plexiglass plate, display is arranged on pushing hands upper, video line connects camera and display, sealing strip is arranged on housing bottom, deflecting roller, BOGEY WHEEL, pushing hands are being arranged on housing, and dividing plate tilts to be arranged in housing, and the suds brush is arranged in the middle of the dividing plate bottom.

Described continous way weld joint vacuum detector is characterized in that: deflecting roller, BOGEY WHEEL, pushing hands handle are installed on described housing.

Described continous way weld joint vacuum detector is characterized in that: described display is arranged on pushing hands on the position that is suitable for operator's observation.

Described continous way weld joint vacuum detector, it is characterized in that: described dividing plate tilts to be arranged in housing, housing is separated into to astrodome and soap water tank, 1 aperture that is communicated with astrodome a and soap water tank b diameter 1mm is arranged at dividing plate top, has an oblong aperture that the suds brush is installed in the middle of the dividing plate bottom.

Described continous way weld joint vacuum detector is characterized in that: described sealing strip (10) is soft shirt rim form sealing strip.

Advantage of the present invention: above-described a kind of continous way large-scale storage tank base plate weld joint vacuum detector, can carry out continuous vacuum detecting to large-scale storage tank base plate weld seam, thereby reduce testing staff's working strength, raising detection efficiency.
