On two sides of the inner cavity of the mounting box 4th is each a sliding groove 5 provided in which an electric slide 6th is slidably connected to which a connecting rod 7th is firmly connected, whose the electric slide 6th remote end with a movable rod 8th is firmly connected to the bottom of the mounting box 4th runs and with a mounting plate 9 is firmly connected. One side of the top of the bottom plate 1 is with a first electric push rod 15th firmly connected, while the other side of the top of the bottom plate 1 with a stand 16 is connected to which a connecting plate 17th is rotatably connected by a rotating shaft. In one of the stand 16 remote end of the connecting plate 17th is a through groove 18th provided in which a sliding wheel 19th is slidably connected, which is rotatably connected to the upper end of the first electric push rod 15th connected is. The connecting plate 17th is through a second electric push rod 20th with a support plate 21 firmly connected to a water tank 22nd and a detector 23 are provided. The detector 23 includes a housing 24 includes, in which a mounting housing 25th is firmly connected in which a warehouse 26th is embedded in which a rotating shaft 27 is provided. On the mounting housing 25th two grooves are provided, in each of which an electric motor 28 is firmly connected, the output shaft of which is connected to a driving gear 29 is firmly connected with a driven gear 30th engaged with one end of the rotating shaft 27 is firmly connected, while the other end of the rotating shaft 27 by a connecting element 31 with a third electric push rod 32 is firmly connected to the connecting element 31 remote end via a mounting element 33 with a probe 34 connected is. One side of the water tank 22nd is with a water pump 35 provided by a water pipe 36 with the inside of the water tank 22nd connected is. In the water tank 22nd remote end of the water pipe 36 is with an annular tube 37 connected to the mounting housing 25th is attached. On the ring-shaped tube 37 is a variety of nozzles 38 intended.

• Bei der Verwendung kann der Erfassungswagen über die Schubstange 41 in einen geeigneten Ort geschoben werden. Dann wird er durch die Befestigungsbox 4 fixiert. Der Betrieb des elektrischen Schiebers 6 wird über das Steuerfeld 42 gesteuert, womit die Verbindungsstange 7 nach unten bewegt werden kann. Die Verbindungsstange 7 treibt die bewegliche Stange 8 zum Bewegen nach unten an. Dadurch wird die Befestigungsplatte 9 nach unten verschoben, bis sie den Fußboden berührt. Dabei ist Lenkrolle 2 nicht beweglich. Die Verbindungsstange 7 stellt sicher, dass sich die bewegliche Stange 8 vertikal nach unten bewegt. Das Reibungsblatt 10 kann die Reibung zwischen der Befestigungsplatte 9 und dem Fußboden erhöhen und somit die Stabilität sicherstellen. Die Zusammenwirkung des Begrenzungsblocks 12 und der Rolle 11 begrenzt die Bewegung der beweglichen Stange 8 und vermeidet es somit, dass der Bewegungsbereich der beweglichen Stange 8 zu groß ist und somit die Oberseite der Befestigungsbox 4 beschädigt wird. Die Form der Rolle 11 kann die Reibung mit dem Begrenzungsblock 12 effektiv reduzieren. Die Feder 14 kann die reibungslose Bewegung der beweglichen Stange 8 unterstützen und wirkt als stoßdämpfender Puffer, wenn sie einer äußeren Kraft ausgesetzt ist. Das Steuerfeld 42 steuert den Betrieb der zweiten elektrischen Schubstange 20, womit die Stützplatte 21 zum Bewegen nach oben und unten angetrieben werden kann, wodurch die Höhenposition des Detektors 23 geändert wird, um die Erfassung der Position in verschiedenen Höhen zu erleichtern. Durch Steuern des Anhebens und des Absenkens der ersten elektrischen Schubstange 15 kann das Gleitrad 19 zum Gleiten in der Durchgangsnut 18 angetrieben werden kann, wodurch die Verbindungsplatte 17 auf dem Standgestell 16 gedreht wird, um die Winkelstellung des Detektors einzustellen und den Umfang der Erfassung zu erweitern. Bei der Erfassung mit dem Detektor 23 wird der Betrieb des Elektromotors 28 gesteuert, um das treibende Zahnrad 29 zum Drehen anzutreiben. Dadurch wird das angetriebene Zahnrad 30 gedreht, dessen Drehung eine Mitdrehung der Drehwelle 27 bewirkt, wodurch die Sonde 34 gedreht wird. Die dritte elektrische Schubstange 32 kann die Sonde 34 vorwärts oder rückwärts schieben. Die Position und die Winkelstellung können durch Steuern des Steuerfelds 42 selbst eingestellt werden, ohne auf manuelle Handeinstellung angewiesen zu sein, womit Zeit und Mühe gespart werden, die Stabilität der Arbeit sichergestellt und die Arbeitseffizienz verbessert wird. Durch Einschalten der Pumpe 35 kann bewirkt werden, dass das Wasser in dem Wassertank 22 durch die Düse 38 ausgestoßen wird, so dass der Zwischenraum zwischen der zu prüfenden Position und der Sonde 34 mit Wasser gefüllt wird, um eine Wasserfilmkopplung zu erreichen.

Working principle:

• When in use, the detection trolley can be moved via the push rod 41 be pushed into a suitable place. Then it is through the mounting box 4th fixed. The operation of the electric slide valve 6th is via the control panel 42 controlled what the connecting rod 7th can be moved down. The connecting rod 7th drives the moving rod 8th to move down. This will make the mounting plate 9 moved down until it touches the floor. There is a swivel castor 2 not movable. The connecting rod 7th makes sure that the moving rod 8th moved vertically downwards. The friction sheet 10 can reduce the friction between the mounting plate 9 and raise the floor and thus ensure stability. The interaction of the boundary block 12th and the role 11 limits the movement of the movable rod 8th thus avoiding the range of motion of the movable rod 8th is too big and thus the top of the mounting box 4th damaged. The shape of the role 11 can reduce the friction with the limiting block 12th effectively reduce. The feather 14th can smooth movement of the moving rod 8th support and act as a shock-absorbing buffer when exposed to an external force. The control panel 42 controls the operation of the second electric push rod 20th , bringing the support plate 21 Can be driven to move up and down, reducing the height position of the detector 23 is changed to make it easier to detect the position at different heights. By controlling the raising and lowering of the first electric push rod 15th can the glide wheel 19th for sliding in the through groove 18th can be driven, making the connecting plate 17th on the stand 16 is rotated to adjust the angular position of the detector and expand the scope of detection. When detecting with the detector 23 becomes the operation of the electric motor 28 controlled to the driving gear 29 to be driven to rotate. This will drive the gear 30th rotated, the rotation of which is a co-rotation of the rotating shaft 27 causes the probe 34 is rotated. The third electric push rod 32 can the probe 34 slide forwards or backwards. The position and angular position can be adjusted by controlling the control panel 42 can be adjusted by yourself without relying on manual manual adjustment, thus saving time and effort, ensuring work stability and improving work efficiency. By switching on the pump 35 can be caused to keep the water in the water tank 22nd through the nozzle 38 is ejected so that the gap between the position to be tested and the probe 34 is filled with water in order to achieve a water film coupling.
