Abstract
The utility model relates to a walking rack of a small corrosion, defect and magnetic leakage detector for ferromagnetic flat plats. The utility model mainly solves the problems that the existing detector has easy detection failure and the labor intensity of operators is large. The utility model is characterized in that a sensor (1), an armature iron (9) and a magnet (2) are transversely connected with the lower part of a vehicle frame (3); a collision prevention block (10) is arranged on the armature iron (9); the lower end of the magnet (2) is connected with a pole shoe (6); the front end of the vehicle frame (3) is fixed with a front walking wheel (4), and the back end of the vehicle frame (3) is hinged with a back walking wheel (5); a shaft of the back walking wheel (5) is hinged with a hand-hold rod (8) of which the lower part is provided with a roller (7). The utility model not only has high detection accuracy rate and carries out continuous scan and detection on the reduced wall with surface corrosion and defects of tank bottom, but also has simple structure and small volume, detects the blind angle which can not be detected by other detection instruments and can also reduce the labor intensity of operators.
Description
Technical field:
The utility model relates to detecting instrument used in the petroleum storage tank field, the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of especially small-sized ferromagnetism instrument walker.
Background technology:
In oil and petrochemical industry and other industry, the storage tank of being made by ferromagnetic metal material constantly increases.Owing under physical environment and liquid level change condition, move all the year round, be subjected to the influence of multiple unfavorable factor, be subjected to various damages inevitably, especially the corrosion failure, the crack propagation that cause of chemical corrosion in the environment and galvanic corrosion and break etc., make dielectric leakage, cause major disaster and environmental pollution,, extent of corrosion is made assessment so at the bottom of needing storage tank in several years, check.And generally use at present and the detecting instrument that generally uses at present when storage tank bottom plate is detected, exist under the heating coil, near the corrosion default of the support column and storage tank corner is difficult for detecting or detect less than and the big problem of labor intensity of operating staff.
The utility model content:
In order to overcome easy omission of existing detector and the big deficiency of labor intensity of operating staff, the utility model provides the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of a kind of small-sized ferromagnetism instrument walker, the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of this small-sized ferromagnetism instrument walker not only detects the accuracy rate height, can subtract the continuous sweep detection to the wall of jar basal surface corrosion default, and it is simple in structure, volume is little, can detect other detecting instruments detect less than the dead angle, also alleviate labor intensity of operating staff.
The technical solution of the utility model is: the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of this small-sized ferromagnetism instrument walker comprises sensor, armature and magnet, sensor, armature and magnet laterally are connected the below of vehicle frame, anti-collision block is housed on the armature, the magnet lower end is connected with pole shoe, the vehicle frame front end is fixed with front walking wheel, the vehicle frame rear end is hinged with rear walking wheel, is hinged with the holding rod of bottom band roller on the rear walking wheel axle.
Sensor adopts magnetism-collected structure in the such scheme, and is covered with the protection box; Sensor is connected under the vehicle frame by bolt; Magnet is permanent magnet.
The utlity model has following beneficial effect: this small-sized ferromagnetism dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting instrument walker is owing to take such scheme, by promoting the walking of detector walker, can pass through multichannel sensor continuous sweep, realize the detection of no dead angle, have the problem that detects the dead angle and alleviated labor intensity of operating personnel with regard to having solved existing detector like this.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-sensor among the figure, 2-magnet, the 3-vehicle frame, the 4-front walking wheel, the 5-rear walking wheel, the 6-pole shoe, the 7-roller, the 8-holding rod, 9-armature, 10-prevents collision block.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1; the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of this small-sized ferromagnetism instrument walker comprises sensor 1; armature 9 and magnet 2; sensor 1 is connected subordinate in the vehicle frame 3 by bolt; sensor 1 adopts magnetism-collected structure; and be covered with the protection box; magnet 2 and armature 9 laterally are connected the middle subordinate of sensor 1 right-hand member vehicle frame 3; magnet 2 lower ends are connected with pole shoe 6; magnet 2 is permanent magnet; anti-collision block 10 is housed on the armature 9; vehicle frame 3 front ends are fixed with front walking wheel 4, and vehicle frame 3 rear ends are hinged with rear walking wheel 5, are hinged with the holding rod 8 of bottom band roller 7 on 5 of the rear walking wheels.
During actual the use, this walker is placed on the detected flat board, promote this walker walking, magnetize by 2 pairs of ferromagnetic metal flat boards of magnet, the dull and stereotyped corrosion default of ferromagnetic metal produces stray field, can show on computers by the continuous sweep information that multichannel sensor 1 is gathered defective, detect the problem that has the easy omission of corrosion default with regard to having solved like this, alleviated labor intensity of operating personnel simultaneously with fixed point.And sensor 1 adopts magnetism-collected structure and highly can regulate; thereby improved the sensitivity of sensor 1; because of sensor 1 is covered with the protection box; so sensor 1 is crashproof; because of rear walking wheel 5 and holding rod 8 employing articulated structures, total can be rotated up and down again, realize the detection of no dead angle; can detect under the heating coil near short edges such as support column is, storage tank bottom plate corner.So the dull and stereotyped corrosion default Magnetic Flux Leakage Inspecting of this small-sized ferromagnetism instrument structure not only detects the accuracy rate height, can subtract the continuous sweep detection to the wall of jar basal surface corrosion default, and simple in structure, can detect present detecting instrument can't detected dead angle.
