Rapid marking device for grid test area of ​​component surface inspection and its usage method

Abstract

This invention discloses a rapid marking device for a grid test area on a component surface and its usage method. The rapid marking device includes a storage mechanism, a matrix grid base mechanism, a marking component, and a positioning mechanism. The positioning mechanism replaces manual labor for rapid movement and adjustment of the grid-like flexible mesh, facilitating the maintenance of its position relative to the beam and improving marking efficiency. For non-planar beam surfaces, a directional telescopic spring is used to adjust the telescopic length according to local concave and convex positions, causing the grid-like flexible mesh to adhere to the component surface. This allows it to adapt well to different testing contact surface environments. Before and after the marking operation, the outer shell and top cover work together to replenish and store the paint. It is convenient to use and can significantly improve the efficiency of setting up test points in the test area, accelerate the testing process, significantly reduce the possibility of human interference, and improve the testing quality.

Description

Technical Field

[0001] This invention relates to the field of engineering technology for component surface inspection. More specifically, this invention relates to a rapid marking device for grid test areas on component surfaces and its method of use. Background Technology

[0002] Many structural component testing parameters involve requirements for the spacing of measuring points. Therefore, many standards stipulate that the testing area for these parameters must be gridded, specifying the grid size and the number of measuring points. For example, the concrete compressive strength rebound method requires 16 measuring points in a 20mm×20mm grid; the rebar corrosion potential requires at least 30 measuring points in a 100mm~300mm grid; and the concrete resistivity requires at least 30 measuring points in a 100mm~300mm grid. It can be seen that structural component testing parameters require a large number of measuring points in the testing area, necessitating the deployment of numerous grid areas, consuming significant technical personnel and preparation time. Given the diverse structural types of components on-site, such as circular columns, square columns, variable cross-section steel bridges, and precast T-beams, and the various curvature surfaces, conventional steel rulers and manual marking are unsuitable, resulting in low testing efficiency, severe disruption to on-site testing progress, and significant human interference.

[0003] In addition, concrete strength is a critical quality control indicator for engineering projects. Ensuring the accuracy and scientific validity of the data obtained from the ultrasonic rebound method is crucial for determining concrete strength. Currently, the ultrasonic rebound method for testing concrete strength in the industry requires drawing absolutely symmetrical positions on two pairs of sides of the beam to arrange measuring points. Most of these measurements are done manually, making it difficult to guarantee that the grid measuring areas on the two pairs of sides of the beam remain precisely symmetrical, which has a certain impact on the accuracy of the data. Summary of the Invention

[0004] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0005] Another objective of this invention is to provide a rapid marking device for the grid testing area on the surface of a component and its usage method, so as to solve the technical problems of low marking efficiency and difficulty in guaranteeing the quality of grid marking devices used on the surface of components in the prior art.

[0006] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides a rapid marking device for a grid test area on a component surface, comprising:

[0007] The storage mechanism includes an outer shell and a top cover. The outer shell has an opening on one side, and the top cover is fitted onto the opening of the outer shell and detachably connected to the edge of the opening. A C-shaped carrying handle is detachably connected to the middle of the outer side of the top cover, and the middle of the carrying handle is parallel to the plane of the top cover.

[0008] A matrix grid base mechanism includes directional guide sleeve rods, which are fixed to the inside of the top cover in a direction perpendicular to the top cover and arranged in a square matrix on the inside of the top cover. A directional telescopic spring is fixed axially inside the directional guide sleeve rod. A sliding rod is connected to the free end of the directional telescopic spring. One end of the sliding rod connected to the directional telescopic spring extends into the directional guide sleeve rod and is slidably connected to the inner wall of the directional guide sleeve rod. A porous absorbent coating layer is connected to one end of all directional guide sleeve rods facing the bottom surface of the outer shell. The edge of the porous absorbent coating layer extends beyond the directional guide sleeve rod.

[0009] The labeling assembly includes directional limiting rods respectively provided for each sliding rod. One end of the directional limiting rod is detachably connected to the free end of a sliding rod. The other end of all the directional limiting rods is fixedly connected to a mesh-like flexible mesh. A porous adsorbent dyeing layer is fixedly connected to the side of the mesh-like flexible mesh facing the porous adsorbent coating layer.

[0010] The positioning mechanism includes a movable frame with a loading arm mounted on its side. The loading arm has an arc-shaped slot along the horizontal direction. The slot is slidably connected to the loading arm. The slot is also fitted with the middle of a carrying rod to lock the carrying rod onto the loading arm.

[0011] Preferably, the mobile frame includes a horizontal beam positioned above the beam body, with vertical moving mechanisms symmetrically arranged at the ends of the beam. The loading arm has an L-shaped structure in the vertical plane, including a vertical arm and a horizontal arm arranged parallel to the beam. The upper end of the vertical arm is connected to the vertical moving mechanism, and the lower end of the vertical arm has a groove along the length of the beam. The horizontal arm passes through the groove and is slidably connected to the vertical arm. The slot is located at one end of the horizontal arm near the middle of the beam. The mobile frame also includes a fixed pulley component, which is symmetrically arranged vertically at the bottom of the beam and horizontally arranged on one side of the vertical arm facing the middle of the beam, for contacting the beam surface on the corresponding side and sliding on the beam surface on the corresponding side along the extension direction of the beam surface.

[0012] Preferably, the vertical moving mechanism includes a base, which is fixedly connected to the crossbeam. A limiting groove is formed vertically through the base. A first rack structure extending vertically is provided on one side of the limiting groove. The side of the limiting groove opposite to the first rack structure is provided as a sliding surface extending vertically. The upper end of the vertical arm passes upward into the limiting groove. The side of the vertical arm facing the first rack structure is provided as a second rack structure, and the side facing away from the first rack structure is slidably connected to the sliding surface. A rotating gear is meshed and connected between the first rack structure and the second rack structure.

[0013] Preferably, the fixed pulley component includes a screw nut seat, a pulley screw, and a directional pulley. One end of the screw nut seat is fixedly connected to the bottom of the corresponding crossbeam or the inner side of the vertical arm, and the other end is threadedly connected to the pulley screw. The end of the pulley screw located outside the screw nut seat is connected to the directional pulley. The directional pulley located at the bottom of the crossbeam has its axial direction aligned with the length direction of the crossbeam. The directional pulley located on one side of the vertical arm has its axial direction vertical. The directional pulley abuts against the surface of the beam on the corresponding side and can slide along the extension direction of the beam surface.

[0014] Preferably, the crossbeam is a horizontally arranged square frame structure, and the vertical moving mechanism is symmetrically arranged on the middle of the left and right sides of the crossbeam in the direction of movement of the fixed pulley component. Each side of the vertical moving mechanism is connected to a loading arm downwards. Fixed pulley components are symmetrically arranged on the front and rear sides of the crossbeam in the direction of movement of the fixed pulley component. The fixed pulley component at the bottom of the crossbeam is used to abut against the top surface of the beam. The fixed pulley components on the loading arms on both sides are arranged opposite each other and are used to abut against the two opposite sides of the beam to be tested. A pair of lifting rods are inserted into the slots on both sides. A pair of mesh-like tough mesh sheets are arranged opposite the two sides of the beam.

[0015] Preferably, the horizontal arm is symmetrically connected to the upper and lower sides of the middle section, and the upper and lower sides of the slide groove are provided with support grooves along the length direction corresponding to the support arms. The support grooves are connected to the slide groove and the length of the support grooves is less than the length of the slide groove. The support arms are located in the support grooves on the corresponding sides. The two sides of the support arms located along the length direction of the horizontal arm are symmetrically connected to the bottom of the corresponding sides of the support grooves with bidirectional limiting springs. The vertical arm has a limiting hole that extends horizontally through the side wall of the slide groove on the horizontal side. The inner wall of the limiting hole is provided with internal threads, and a fastening bolt is screwed into the limiting hole. A washer is fitted on the fastening bolt. The fastening bolt can pass through the limiting hole and abut against the horizontal arm to restrict the movement of the horizontal arm.

[0016] On the other hand, the present invention also provides a method for using a rapid marking device for a grid area of ​​a component surface inspection, comprising the following steps:

[0017] S1. Determine the size of the test area according to the test parameters and the requirements of the test method, and select the marking component with the required grid size;

[0018] S2. Determine the position of the test area marking according to the specification requirements, and detachably connect the end of the directional limiting rod away from the mesh-like tough mesh to the sliding rod. The marking assembly, the matrix mesh base mechanism and the top cover are integrated into one unit.

[0019] S3. Determine the required position for the rapid marking device of the component surface detection grid area on the beam body according to the detection area line position in step S2, and clean the impurities on the corresponding position of the beam body surface.

[0020] S4. Using the directional telescopic spring, press the side of the top cover connected to the labeling assembly toward the inside of the outer shell, so that the porous absorbent dyeing layer on the mesh-like tough mesh is pressed into the porous absorbent coating layer to obtain the dyeing coating.

[0021] S5. Install the loading arm on the mobile frame, insert the slot into the loading arm, with the slot facing directly below the crossbeam, place the positioning mechanism on the top of the beam, so that the slot is perpendicular to the side of the beam where the detection area is located, move the mobile frame into place, adjust the distance between the slot and the side surface of the beam, and vertically embed the handle into the slot, with the mesh-like tough mesh facing the detection area on the beam;

[0022] S6. Press the top cover toward the beam and squeeze the directional telescopic spring at a uniform speed until all the contact points on the mesh-like toughness mesh are in contact with the test surface.

[0023] S7. Disconnect the mesh-like toughness mesh from the test surface, and move the positioning mechanism to the next position to be drawn as required. Repeat the above operation until the number of meshes that meet the specifications is obtained.

[0024] S8. Complete the grid line marking work, remove the quick marking device for the surface detection grid area from the beam, disengage the handle from the slot, and press the top cover into the outer shell until the top cover and the edge cover of the outer shell are merged to form a detachable connection for storage.

[0025] Preferably, when the support arm is not in operation, it is located in the middle of the support groove. When the top cover is continuously pressed towards the beam, the directional telescopic spring contracts, and the upper and lower bidirectional limiting springs on the side near the beam are compressed and contracted by the corresponding support arm. The fastening bolt is screwed into the limiting hole until the fastening bolt passes through the limiting hole and abuts against the horizontal arm, temporarily locking the position of the horizontal arm in the horizontal groove. When the mesh-like toughness mesh is separated from the test surface, the fastening bolt is loosened in the opposite direction. Under the restoring deformation action, the bidirectional limiting springs on both sides of the support arm in the horizontal direction push the support arm to move away from the beam, so that the mesh-like toughness mesh automatically detaches from the side of the beam, and the support arm returns to its original position.

[0026] The present invention has at least the following beneficial effects:

[0027] (1) The rapid marking device for the surface inspection grid area of ​​the component of the present invention, by using multiple directional telescopic springs arranged in an array and a mesh-like tough mesh with a certain toughness, can adjust the telescopic length according to the local unevenness of the component surface, so that the mesh-like tough mesh fits the component surface. It can quickly arrange the grid area for various detection parameters such as steel corrosion potential, ultrasonic rebound combined method of concrete compressive strength, and concrete resistivity, accurately and efficiently draw the required grid for detection, and has a wide range of applications.

[0028] (2) The rapid marking device for the grid test area of ​​the component surface detection of the present invention has the characteristics of being easy to carry, store and use, and having high grid drawing efficiency. The porous adsorption coating layer is set as a storage warehouse for the coating. By pressing the top cover into the storage shell, the porous adsorption dyeing layer on the grid-shaped tough mesh can come into contact with the porous adsorption coating layer and exchange coatings. When drawing the grid, the coating on the porous adsorption dyeing layer can be drawn on the component surface by pressing the top cover toward the component surface. This helps to reduce the manual inspection, reduce the inspection cost and improve the work efficiency.

[0029] (3) This invention sets loading arms and marking components on the two pairs of sides of the beam to be tested respectively. The fixed pulley components at the bottom of the crossbeam and the side of the vertical arm support and limit the positioning mechanism in the vertical and horizontal directions, ensuring that the marking components can maintain stable directional movement when they reach the test area. The marking components on both sides of the beam can move synchronously and symmetrically and draw grids relative to each other, which significantly improves the accuracy of the ultrasonic rebound method for measuring the compressive strength of concrete, reduces human interference, and realizes semi-automatic ultrasonic side method test point layout.

Therefore, they should not be construed as limitations on this invention.

[0041] like Figure 1-3 As shown in Figures 6 and 7, the present invention provides a rapid marking device for a grid area of ​​a component surface inspection, comprising:

[0042] The storage mechanism includes an outer shell 2 and a top cover 3. The outer shell 2 has an opening on one side, and the top cover 3 is fitted onto the opening of the outer shell 2 and is detachably connected to the edge of the opening of the outer shell 2. A C-shaped handle 4 is detachably connected to the middle of the outer side of the top cover 3, and the middle of the handle 4 is parallel to the plane of the top cover 3.

[0043] The matrix grid base 21 mechanism includes a directional guide sleeve rod 5, which is fixed to the inside of the top cover 3 in a direction perpendicular to the top cover 3 and arranged in a square matrix on the inside of the top cover 3. A directional telescopic spring 6 is fixed axially inside the directional guide sleeve rod 5. A sliding rod 7 is connected to the free end of the directional telescopic spring 6. One end of the sliding rod 7 connected to the directional telescopic spring 6 extends into the directional guide sleeve rod 5 and is slidably connected to the inner wall of the directional guide sleeve rod 5. A porous absorbent coating layer 8 is connected to one end of all directional guide sleeve rods 5 facing the bottom surface of the outer shell 2. The edge of the porous absorbent coating layer 8 extends beyond the directional guide sleeve rod 5.

[0044] The labeling assembly includes a directional limiting rod 9 provided for each sliding rod 7. One end of the directional limiting rod 9 is detachably connected to the free end of a sliding rod 7. The other ends of all the directional limiting rods 9 are fixedly connected to a mesh-like flexible mesh 10. A porous absorbent dyeing layer 11 is fixedly connected to the side of the mesh-like flexible mesh 10 facing the porous absorbent coating layer 8.

[0045] The positioning mechanism includes a movable frame 12, a loading arm 13 is provided on the side of the movable frame 12, and an arc-shaped slot 14 is provided on the loading arm 13 along the horizontal direction. The slot 14 is slidably connected to the loading arm 13, and the slot 14 is configured to cooperate with the middle of the handle 4 to lock the handle 4 on the loading arm 13.

[0046] The rapid marking device for the grid area of ​​component surface inspection in this embodiment can be used in the following steps:

[0047] S1: According to the requirements of the detection method corresponding to the detection parameters, determine the size of the detection area, select the mesh-like tough mesh sheet 10 of different sizes (number of meshes, size of mesh units) and the required coating, and add the coating to the porous absorbent coating layer 8 as a coating reserve. The mesh-like tough mesh sheet 10 is a steel mesh sheet made of steel fiber, which has a certain toughness and can be bent at a certain angle and recover its deformation to adapt to the surface of the component to be coated with different shapes. The outer shell 2 and the top cover 3 are preferably square structures.

[0048] S2: Determine the marking position of the test area according to the specification requirements, weld and fix the mesh-like tough mesh 10 to the directional limiting rod 9, and then detachably connect the directional limiting rod 9 to the sliding rod 7. One end of the sliding rod 7 is installed in the directional sliding sleeve rod 5 and can move along the axial direction of the directional sliding sleeve rod 5 through the directional telescopic spring 6 set in the same axis, thereby connecting the top cover 3, the matrix mesh base 21 mechanism and the marking assembly into one, forming the prepared marking main structure;

[0049] S3. Determine the required position for the rapid marking device of the detection grid area on the component surface on the beam 1 according to the position of the detection area line drawing in step S2, and clean the impurities on the surface of the beam 1 at the corresponding position.

[0050] S4: Press the assembled labeling main structure into the storage shell through the top cover 3, and use the directional telescopic spring 6 to drive the mesh-like tough mesh 10 to press the porous absorbent dyeing layer 11 into the porous absorbent coating layer 8 to exchange and obtain the dyeing coating.

[0051] S5: Install the loading arm 13 on the mobile frame 12, insert the slot 14 into the loading arm 13, with the slot 14 facing directly below the crossbeam 15. Place the positioning mechanism at the top near the detection area of ​​the beam 1, so that the slot 14 is perpendicular to the side of the beam 1 where the detection area is located. After moving the mobile frame 12 into place, adjust the distance between the slot 14 and the lateral surface of the beam 1 to ensure that the subsequent installation position of the main labeling structure is appropriate from the surface of the beam 1. Secure the main labeling structure using the handle 4. The handle 4 is inserted into the slot 14 of the loading arm 13. The inner side of the slot 14 is a non-smooth surface. It can be stably inserted when the weight of the top cover 3, the matrix grid base 21 mechanism, and the marking component is not large. The specific shape of the slot 14 can also be designed as needed to ensure that it is easy to install and disassemble and that the connection is stable. At this time, the middle part of the handle 4 is located vertically, the directional guide sleeve rod 5, the sliding rod 7, and the directional limit rod 9 are located horizontally, and the grid-like tough steel sheet is located vertically, parallel to the surface of the detection area of ​​the beam 1.

[0052] S6: Push the top cover 3 toward the surface of the component at a uniform speed, and move the slot 14 synchronously until all the contact points on the mesh-like tough mesh 10 are in contact with the test surface. Apply the mesh-like dyeing paint to the corresponding position on the surface of the beam 1.

[0053] S7: Pull back the slot 14 to detach the mesh-like tough mesh 10 from the test surface of the beam 1, and repeat the above operation as required until the number of meshes required by the specification is met, and then store it through the storage shell.

[0054] The rapid marking device for the grid test area of ​​the component surface inspection in this embodiment includes a storage mechanism, a matrix grid base 21 mechanism, a marking component, and a positioning mechanism. The top cover 3 is mounted on the loading arm 13. The moving frame 12 of the positioning mechanism replaces manual labor for rapid movement and adjustment of the grid-like flexible mesh sheet 10, and facilitates maintaining its position relative to the beam 1, thus improving marking efficiency. For non-planar and uneven surfaces of the beam 1, when the top cover 3 with the marking component is pressed towards the surface of the beam 1, the directional telescopic spring 6 set at the corresponding position changes the telescopic length according to the local unevenness, so that the flexible grid-like flexible mesh sheet 10 fits into the component surface. It can adapt well to different inspection contact surface environments and ensure grid marking. The quality is ensured by setting a matching storage structure between the top cover 3 and the outer shell 2, which stores and protects the marking component inside the outer shell 2, making it easy to carry and transfer. After the top cover 3 is pressed into the outer shell 2, under the action of the set directional telescopic spring 6, the porous adsorbent dyeing layer 11 installed on the mesh-like tough mesh 10 approaches and even contacts the porous adsorbent coating layer 8 above to obtain supplementary coating. The matrix mesh base 21 mechanism and the marking component are installed on the top cover 3, which also facilitates the uniform application of pressure. The rapid marking device for the entire component surface detection grid test area is portable and easy to use. The grid marking speed is fast and it can be used for different detection parameters and different component surface conditions. It has a wide range of applications and is conducive to improving the detection efficiency of the test area on site and saving detection time.

[0055] In another technical solution, such as Figure 1 , 3 As shown in Figure -5, the mobile frame 12 includes a horizontal beam 15 positioned above the beam 1. A vertical moving mechanism 16 is symmetrically arranged at the end of the horizontal beam 15. The loading arm 13 has an L-shaped structure in the vertical plane, including a vertical arm 17 and a horizontal arm 18 parallel to the horizontal beam 15. The upper end of the vertical arm 17 is connected to the vertical moving mechanism 16. The lower end of the vertical arm 17 has a groove 19 along the length of the horizontal beam 15. The horizontal arm 18 passes through the groove 19 and is slidably connected to the vertical arm 17. A slot 14 is located at one end of the horizontal arm 18 near the middle of the horizontal beam 15. The mobile frame 12 also includes a fixed pulley component 20. The fixed pulley component 20 is symmetrically arranged vertically at the bottom of the horizontal beam 15 and horizontally arranged on one side of the vertical arm 17 facing the middle of the horizontal beam 15. It is used to contact the surface of the beam 1 on the corresponding side and can slide along the extension direction of the beam 1 surface on the corresponding side.

[0056] When the movable frame 12 is set on the surface to be tested of beam 1, the pulleys of the fixed pulley components 20 slide along the beam axis to adjust the position of the crossbeam 15. The height of the corresponding side is adjusted by the symmetrically arranged fixed pulley components 20 at the bottom, so that the crossbeam 15 is horizontal and the vertical arm 17 is vertical. Thus, when the vertical moving mechanism 16 drives the vertical arm 17 to move, it remains vertical. At this time, the cross arm 18 faces the side of the beam 1 where the test area is located, and simultaneously, the fixed pulleys on the fixed pulley components 20 on the side of the vertical arm 17 contact the side of the beam 1, i.e., the test surface, ensuring that the pulleys of all fixed pulley components move along the beam axis. The fixed pulley component can stabilize the overall device and directional movement. Then, the handle 4 is installed on the slot 14. The slot 14 can slide relative to the slide groove 19 along the length of the crossbeam 15. The mesh-like tough mesh 10 is adjusted to an appropriate position from the test surface of the beam 1 when the directional telescopic spring 6 is not under pressure. Then, the height position of the loading arm 13 and the marking component is adjusted by the translational movement frame 12 and the vertical movement mechanism 16 to reach the required marking grid area. Press the top cover 3 by hand until all the contact points of the mesh-like tough mesh 10 are in contact with the test surface to complete the grid line marking work.

[0057] In another technical solution, such as Figure 1 , 3 As shown, the vertical moving mechanism 16 includes a base 21, which is fixedly connected to the crossbeam 15. A limiting groove 22 is vertically opened on the base 21. A vertically extending first rack structure 23 is provided on one side of the limiting groove 22. The side of the limiting groove 22 opposite to the first rack structure 23 is provided as a vertically extending sliding surface. The upper end of the vertical arm 17 passes upward into the limiting groove 22. The side of the vertical arm 17 facing the first rack structure 23 is provided as a second rack structure 24, and the side facing away from the first rack structure 23 is slidably connected to the sliding surface. A rotating gear 25 is meshed and connected between the first rack structure 23 and the second rack structure 24.

[0058] By setting up a structure in which the first rack structure 23, the second rack structure 24, and the meshing transmission gear 25 cooperate, when the second rack structure 24 is pressed down, the gear 25 rotates downward, and under the meshing action, the second rack structure 24 moves downward. Similarly, when the second rack structure 24 is pulled up, the gear 25 rotates upward, and under the meshing action, the second rack structure 24 moves upward. Of course, an additional locking structure can be set to more stably lock the relative position of the second rack structure 24, such as setting a clip on the part of the second rack structure 24 exposed in the limiting groove 22.

[0059] In another technical solution, such as Figure 1 , 3As shown, the fixed pulley component 20 includes a screw nut seat 26, a pulley screw 27, and a directional pulley 28. One end of the screw nut seat 26 is fixedly connected to the bottom of the corresponding crossbeam 15 or the inner side of the vertical arm 17, and the other end is threadedly connected to the pulley screw 27. The end of the pulley screw 27 located outside the screw nut seat 26 is connected to the directional pulley 28. The directional pulley 28 located at the bottom of the crossbeam 15 has its axial direction aligned with the length direction of the crossbeam 15. The directional pulley 28 located on one side of the vertical arm 17 has its axial direction vertical. The directional pulley 28 abuts against the surface of the beam 1 on the corresponding side and can slide along the extension direction of the surface of the beam 1.

[0060] By setting the fixed pulley component 20 as a screw-type mating structure, when it is necessary to adjust the distance between the directional pulley 28 and the surface of the beam 1, the pulley screw 27 is pushed towards the screw nut seat 26, and the pulley screw 27 moves in a straight line. Thus, while adjusting the spacing, the direction of movement of the directional pulley 28 remains unchanged. The two fixed pulley components 20 symmetrically arranged at the bottom of the crossbeam 15 can be flexibly and independently adjusted according to the local conditions of the corresponding position of the beam 1, ensuring that the crossbeam 15 remains horizontal. Furthermore, by setting the directional pulleys 28 at the bottom of the crossbeam 15 and on the side of the vertical arm 17 respectively, which abut against the corresponding side surface of the beam 1, it is beneficial to ensure that the entire marking assembly can move in a directional and stable manner on the positioning mechanism.

[0061] In another technical solution, such as Figure 3 As shown, the crossbeam 15 is a horizontally arranged square frame structure. The vertical moving mechanism 16 is symmetrically arranged on the middle of the left and right sides of the crossbeam 15 in the direction of movement of the fixed pulley component. Each side of the vertical moving mechanism 16 is connected to a loading arm 13 downwards. Fixed pulley components 20 are symmetrically arranged on the front and rear sides of the crossbeam 15 in the direction of movement of the fixed pulley component. The fixed pulley component at the bottom of the crossbeam 15 is used to abut against the top surface of the beam 1. The fixed pulley components on the loading arms 13 on both sides are arranged opposite each other and are used to abut against the two opposite sides of the beam 1 to be tested. A pair of lifting rods 4 are inserted into the slots 14 on both sides. A pair of mesh-like tough mesh sheets 10 are arranged opposite the two sides of the beam 1.

[0062] The crossbeam 15 is designed as a square structure with four equal sides, as shown in the example. Figure 3The upper and lower ends are equipped with fixed pulley components for directional movement. Vertical moving mechanisms 16 and fixed pulley components are symmetrically arranged downwards on the left and right sides. For testing environments requiring the drawing of absolutely symmetrical positions of measuring points on two pairs of sides of the beam 1, two loading arms 13 are symmetrically arranged on the vertical moving mechanisms 16 at both ends of the crossbeam 15. The fixed pulley components on the two loading arms 13 respectively abut against the two pairs of sides of the beam 1. Vertical support is provided by the fixed pulley components at the bottom of the crossbeam 15, and horizontal support is provided by the fixed pulley components on the sides of the vertical arm 17. The movement direction of the fixed pulley component is on a straight line that is parallel to each other. The fixed pulley component can drive the moving frame 12 to move in a directional direction along the extension direction of the beam 1. The vertical position of the loading arms 13 on both sides of the beam 1 is adjusted symmetrically by the vertical moving mechanism 16. The distance between the slot 14 and the side of the beam 1 is adjusted symmetrically by the sliding action of the slide groove 19 and the cross arm 18. After the handle 4 is inserted, the positions of the mesh-like tough mesh 10 on both sides are exactly the same and symmetrical. This applies pressure to the top cover 3 on both sides and obtains the corresponding mesh lines on both sides of the beam 1.

[0063] In another technical solution, such as Figure 1 , 4 As shown in Figure 6, the horizontal arm 18 is symmetrically connected to the upper and lower sides of the middle section with support arms 29. The upper and lower sides of the slide groove 19 are provided with support grooves 30 along the length direction corresponding to the support arms 29. The support grooves 30 are connected to the slide groove 19 and the length of the support grooves 30 is less than the length of the slide groove 19. The support arms 29 are located in the support grooves 30 on the corresponding sides. The two sides of the support arms 29 located along the length direction of the horizontal arm 18 are symmetrically connected to the bottom of the corresponding sides of the support grooves 30 with bidirectional limiting springs 31. The vertical arm 17 has a limiting hole 32 that runs through the horizontal direction on the side wall of the slide groove 19 on the horizontal side. The inner wall of the limiting hole 32 is provided with internal threads. A fastening bolt 33 is screwed on the limiting hole 32. A washer 34 is sleeved on the fastening bolt 33. The fastening bolt 33 can pass through the limiting hole 32 and abut against the horizontal arm 18 to restrict the movement of the horizontal arm 18.

[0064] Support arm 29 is positioned in the middle of support groove 30. Along the length of support groove 30, two sides of support arm 29 are connected to the corresponding bottom sides of support groove 30 by bidirectional limiting springs 31. Thus, when support arm 29 deviates from the middle of support groove 30, the bidirectional limiting springs 31 on both sides can apply tension or thrust respectively, forming a bidirectional limiting effect, allowing support arm 29 to automatically return to its original position. Support arm 29 structures are symmetrically arranged on the upper and lower sides of horizontal arm 18, with corresponding support grooves 30 and bidirectional limiting springs 31, ensuring that the force applied to horizontal arm 18 to restore its position is uniform and symmetrical. This ensures that the mesh-like flexible mesh sheet 10 always remains vertical, which is beneficial for ensuring the quality of mesh drawing. When external force compresses the top cover 3, except for the directional telescopic springs… In addition to being compressed, the bidirectional limiting spring 31 at the support arm 29 is also subjected to force. The support arm 29 is in a non-central position within the support groove 30. The fastening bolt 33 is screwed into the limiting hole 32 to press against and tighten the cross arm 18. The friction force is used to lock the cross arm 18 in place. When the marking component reaches the optimal distance from the surface of the beam 1, the cross arm 18 is limited, which does not affect the subsequent continuous pressure on the top cover 3. Between the fastening bolt 33 and the cross arm 18, after the fastening bolt 33 applies pressure against the cross arm 18, the friction force between the fastening bolt 33 and the cross arm 18 is greater than the resultant force of the restoring deformation applied by all the bidirectional limiting springs 31 to the support arm 29, thereby ensuring that the position of the cross arm 18 relative to the slide groove 19 can be stably locked.

[0065] This invention also provides a method for using a rapid marking device for a grid testing area on the surface of a component, combined with... Figure 1-7 As shown, it includes the following steps:

[0066] S1. Determine the size of the test area according to the test parameters and the requirements of the test method, and select the marking component with the required grid size;

[0067] S2. Determine the position of the test area marking according to the specification requirements, and detachably connect the end of the directional limiting rod 9 away from the mesh tough mesh 10 to the sliding rod 7. The marking assembly, the matrix mesh base 21 mechanism and the top cover 3 are integrated.

[0068] S3. Determine the required position for the rapid marking device of the detection grid area on the component surface on the beam 1 according to the position of the detection area line drawing in step S2, and clean the impurities on the surface of the beam 1 at the corresponding position.

[0069] S4. Using the directional telescopic spring 6, press the side of the top cover 3 connected to the labeling component into the outer shell 2, so that the porous absorbent dyeing layer 11 on the mesh-like tough mesh 10 is pressed into the porous absorbent coating layer 8 to obtain the dyeing coating.

[0070] S5. Install the loading arm 13 on the mobile frame 12, insert the slot 14 into the loading arm 13, the slot 14 is set facing directly below the crossbeam 15, place the positioning mechanism on the top of the beam 1, so that the slot 14 is perpendicular to the side of the detection area on the beam 1, after the mobile frame 12 moves into place, adjust the distance between the slot 14 and the side surface of the beam 1, and embed the handle 4 vertically into the slot 14, with the mesh-like tough mesh 10 facing the detection area on the beam 1;

[0071] S6. Press the top cover 3 toward the beam 1 and squeeze the directional telescopic spring 6 at a uniform speed until all the contact points on the mesh-like tough mesh 10 are in contact with the test surface.

[0072] S7. Disconnect the mesh-like tough mesh 10 from the test surface, and move the positioning mechanism to the next position to be drawn as required. Repeat the above operation until the number of meshes that meet the specifications is obtained.

[0073] S8. Complete the grid line marking work, remove the quick marking device for the surface detection grid area from the beam 1, disengage the handle 4 from the slot 14, and press the top cover 3 into the outer shell 2 until the top cover 3 and the opening edge cover of the outer shell 2 merge to form a detachable connection for storage.

[0074] This method utilizes a rapid marking device for the grid testing area on the component surface to draw a grid on the surface of the component beam 1. The installation and disassembly operations are simple and convenient, and the grid-shaped flexible mesh sheet 10 can be replaced according to different grid specifications. Under the action of the directional telescopic spring 6, continuous pressure is applied towards the component surface to achieve adhesion between the grid-shaped flexible mesh sheet 10 and the component surface, ensuring the quality of the grid drawing. Before and after use, the paint is replenished and stored through the cooperation of the outer shell 2 and the top cover 3. It is convenient to use and can significantly improve the efficiency of the detection area and test point layout of various methods, speed up the detection process, significantly reduce the possibility of human interference, and improve the detection quality.

[0075] In another technical solution, such as Figure 1 , 4As shown in Figure 7, when the support arm 29 is not in operation, it is located in the middle of the support groove 30. When it continuously presses the top cover 3 towards the beam 1, the directional telescopic spring 6 contracts. The upper and lower bidirectional limiting springs 31 on the side near the beam 1 are compressed and contracted by the corresponding support arm 29. The fastening bolt 33 is screwed into the limiting hole 32 until the fastening bolt 33 passes through the limiting hole 32 and abuts against the horizontal arm 18, temporarily locking the position of the horizontal arm 18 in the horizontal groove. When the mesh-like tough mesh 10 is separated from the test surface, the fastening bolt 33 is loosened in the opposite direction. Under the restoring deformation action, the bidirectional limiting springs 31 on both sides of the support arm 29 push the support arm 29 to move away from the beam 1, so that the mesh-like tough mesh 10 automatically separates from the side of the beam 1, and the support arm 29 returns to its original position.

[0076] By setting up a cooperative structure between the support arm 29 and the bidirectional limiting spring 31, the top cover 3 is pressed down to assist in pressing the marking grid lines, reducing the difficulty of manual operation and improving the efficiency of manual grid drawing.

They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
