Description

Technical Field

[0001] The utility model relates to a flaw detection device, in particular to an adjustable steel plate flaw detection vehicle. Background Art

[0002] Steel plates can be flaw detected by a flaw detection trolley. A Chinese patent with the publication number of "CN117110429A" discloses a multi-probe plate flaw detection trolley, which includes a bracket. The bottom of the bracket is connected with multiple probes through a universal mechanism, and a moving component for moving the bracket is also arranged on the bracket. For this flaw detection trolley, the moving component drives the bracket to move on the surface of the steel plate, and multiple probes at its bottom are used to perform flaw detection operations on the steel plate. For the flaw detection trolley with this structure, the coupling effect between the probes and the steel plate surface is poor. In order to make the probes fit the steel plate surface, during the walking process, the operator needs to apply a force obliquely upward to the top of the probe bracket, so that the bracket can use the rear roller as a fulcrum to apply a force to several probes at the front end of the bracket, so as to make it fit the steel plate surface. This operation method is not only inconvenient for applying force, but also difficult to control the force, and it is easy to cause fatigue after long-term operation. In addition, there are also some flaw detection trolleys that achieve probe coupling through the self-weight or load of the probe holder, but due to their overall heavy weight, they are not easy to adjust. Summary of the Invention

[0046] The setting of the L-shaped driving member enables the operator to drive the hanging bracket and the probe assembly to rise and fall along the guide rail or slider on the vehicle body through the vertical rod of the L-shaped driving member, so that the probe can be attached to or separated from the surface of the steel plate. Compared with the existing flaw detector cart, its operation is more convenient, the labor intensity is lower, and the operator can easily control the pressing force between the probe and the steel plate to ensure the coupling between the probe and the steel plate, thereby improving the flaw detection effect.

[0047] Among them, the vehicle body is used to install components such as the probe assembly and the L-shaped driving member. There are several walking wheels provided below the bottom plate of the vehicle body. In this embodiment, the number of walking wheels is four, and the four walking wheels are installed on the bottom surface of the bottom plate. The bracket is installed above the bottom plate, and its bottom end is fixedly connected to the bottom plate. The bracket is formed by connecting several steel materials or profiles. Specifically, the bracket includes two vertical struts 13 whose bottom ends are fixedly connected to the bottom plate, and two diagonal struts 14 whose bottom ends are fixedly connected to the bottom plate and whose tops are fixedly connected to the vertical struts. The vertical struts and the diagonal struts are fixedly connected by several connecting rods 15. A handle 16 for facilitating the operator to push the vehicle body is also provided at the top of the diagonal strut.

[0048] An operating platform 17 is provided at the top of the bracket. A display touch screen 18 is provided on the surface of the operating platform. An installation box 19 for placing the power supply is fixedly connected below the operating platform.

[0049] A main chassis 20 is also fixedly provided between the two diagonal struts, and the flaw detection host is arranged inside the main chassis.

[0050] At the edge of the operating platform close to the L-shaped driving member, a second guiding hole 21 for limiting and guiding the vertical rod is provided. In this embodiment, an angle steel 22 is fixedly provided at the edge of the operating platform, and the second guiding hole is provided on the surface of the angle steel.

[0051] The second guiding hole and the L-shaped driving member are basically located in the same vertical plane. A push rod 23 is provided at the top end of the vertical rod of the L-shaped driving member. The push rod or the vertical rod passes through the second guiding hole to realize the guiding and limiting functions of the L-shaped driving member.

[0052] In order to realize the limiting of the L-shaped driving member and the automation function of the adjustable steel plate flaw detection vehicle, proximity switches 24 are respectively provided at both ends of the second guiding hole. The flaw detection host can turn on or off components such as the water pump and the probe according to the signals of the proximity switches to realize automatic flaw detection.

[0053] The L-shaped driving member is used to drive the probe assembly to lift, so that several probes on the probe frame can be closely attached to the surface of the steel plate, thereby realizing the flaw detection of the steel plate.

[0054] The L-shaped driving member includes a vertical rod and a horizontal rod, and the vertical rod and the horizontal rod are basically perpendicular to each other. The bottom end of the vertical rod is fixedly connected to one end of the horizontal rod.

[0055] The middle part of the L-shaped driving member is rotatably arranged on the vehicle body. In this embodiment, a connecting shaft 25 is provided on the bracket. Connecting holes 26 are provided at the bottom end of the vertical rod and the rear end of the horizontal rod. The end parts of the connecting shaft respectively pass through the connecting holes at the bottom end of the vertical rod and the end of the horizontal rod. The vertical rod and the horizontal rod are also connected by a fixing pin 27. The fixing pin and the connecting shaft realize the fixation of the vertical rod and the horizontal rod, and the L-shaped driving member can rotate around the connecting shaft, thereby driving the probe frame at the front end of the horizontal rod to lift.

[0056] The probe frame is provided at the front end of the cross bar through a number of hanging brackets. The front end of the cross bar has a first guiding hole, and a connecting pin is arranged in the first guiding hole. Both ends of the connecting pin are respectively arranged at the top ends of the hanging brackets, and the bottom ends of the hanging brackets are fixedly arranged on the probe frame through bolts. When the probe frame moves up and down, the connecting pin moves in the first guiding hole, so that the probe frame can move up and down along the slider on the vehicle body surface.

[0057] The probe frame is used to install a number of probes. In this embodiment, the probe frame is a rectangular frame structure, which includes two mounting rods 28 arranged parallel up and down. Connecting plates 29 are respectively arranged at both ends of the mounting rods, and the upper and lower ends of the connecting plates are fixedly connected to the corresponding mounting rods. The mounting rods can be made of profiles. The probe frame is slidably arranged on the vehicle body through a guide rail assembly. Specifically, the guide rail assembly includes guide rails 30 fixedly arranged on the surface of the connecting plates. A number of probes are fixed to the bottom of the probe frame through probe seat assemblies 31. A slider mounting plate 32 is arranged at the front end of the vehicle body, and sliders 33 adapted to the guide rails are respectively arranged on the left and right sides of the slider mounting plate. During operation, the probe frame and the hanging brackets at its top are vertically lifted and lowered along the sliders on both sides of the probe frame under the drive of an L-shaped driving member, so that the probes can be closely attached to the plate.

[0058] The probe is used to detect the flaws of the plate, and it is arranged on the probe frame through a probe seat assembly.

[0059] In this embodiment, the probe seat assembly includes an adjusting seat 34 connected to the mounting rod. The adjusting seat is locked on the mounting rod at the lower side of the probe frame through a locking bolt 35. A lifting plate 36 is arranged on the front surface of the adjusting seat. The lifting plate and the adjusting seat are slidably matched through a guide bar 37 and a sliding seat 38. A spring 39 is connected between the top end of the lifting plate and the adjusting seat. The spring can drive the lifting plate to descend, so as to press the probe at the bottom end of the lifting plate against the surface of the steel plate.

[0060] A U-shaped seat 40 is arranged at the bottom end of the lifting plate. The probe is installed on the U-shaped seat. The middle part of the U-shaped seat is hinged to the bottom end of the lifting plate, and both sides of the probe are hinged to the U-shaped seat. The probe seat assembly with this structure enables the probe to adapt to the uneven surface of the steel plate.

[0061] In order to protect the probe assembly and prevent the probe from colliding with objects in front of or on both sides of the vehicle body and being damaged, a collision prevention frame 41 is arranged at the front end of the vehicle body. The rear end of the collision prevention frame is fixedly arranged on the vehicle body, and the front end of the collision prevention frame is located in front of the probe assembly. The whole probe assembly is surrounded by the collision prevention frame to prevent the probe from colliding with objects in front of or on both sides of the vehicle body and being damaged.

[0062] To achieve positioning, an encoder assembly is further provided on the probe frame. The encoder assembly includes an encoder fixing bracket 42 fixedly connected to the probe frame and an encoder 43 provided on the encoder fixing bracket. A roller 44 is connected to the input shaft of the encoder. The roller is located below the bottom plate. When the L-shaped driving member drives the probe frame to descend and makes the probe closely fit the steel plate, the roller provided on the probe frame just contacts the surface of the steel plate. When the operator pushes the vehicle body forward, the roller rolls on the surface of the steel plate, and the encoder can sense the moving distance of the vehicle body.

[0063] To further improve the coupling effect between the probe and the steel plate, a water tank 45 is also provided on the probe frame. The water tank is fixedly arranged on the mounting rod on the upper side of the probe frame. The water tank is integrally strip-shaped, and a plurality of water outlet interfaces 46 are provided on its front side. The water outlet interfaces are connected to the water inlet of the corresponding probe through pipes. The water inlet of the water tank is connected to the water outlet end of a water pump 47 through a pipe, and the water pump can be directly arranged on the surface of the bottom plate.

[0064] The following is the specific working process of the adjustable steel plate flaw detector vehicle.

[0065] The operator first adjusts the position of the adjusting seat on the probe frame and locks it on the mounting rod through the locking bolt. During flaw detection, the operator pushes the vehicle body forward through the handle, and at the same time pushes the vertical rod through the push rod to make the L-shaped driving member rotate a certain angle around the connecting shaft. When the L-shaped driving member rotates, the hanger at the front end of the cross bar moves along the first guiding hole, and at the same time drives the probe frame fixedly connected thereto to descend until a plurality of probes at the bottom of the probe frame are pressed tightly against the surface of the steel plate.

[0066] During the pressing process, the lifting plate and the U-shaped seat can overcome the elastic force of the spring and rise relative to the adjusting seat under the action of the steel plate, and the driving plate, the U-shaped seat and the probe plate are further pressed tightly against the surface of the steel plate under the reaction force of the spring.

[0067] After the flaw detection is completed, all components are reset for the next flaw detection.
