As the base of an automobile, the girder is generally supported on the wheels via a suspension device, a front axle, and a rear axle. It mainly plays the role of supporting and connecting each assembly of the automobile and bearing various loads inside and outside the automobile. After the production and manufacturing of the girder are completed, it is necessary to detect the structure of the girder to prevent defective girders with cracks from entering the market.

[0003] In the prior art, such as "A Truck Girder Detection Device" with Chinese Patent No. CN109738457A, it includes a vehicle girder body. A support column is movably connected to the bottom of the vehicle girder body. A cross bar is fixedly connected to the side surface of the support column. A support bar is fixedly connected to the upper surface of the cross bar. A support plate is fixedly connected to the upper surface of the support bar. A connecting plate is fixedly connected to the back surface of the vehicle girder body. A first sliding groove is opened on the front surface of the vehicle girder body. A fixing plug is clamped in the first sliding groove. A first slider is slidably connected to the inner wall of the first sliding groove. A connecting rod is fixedly connected to the front surface of the first slider.

[0004] However, in the prior art, it is necessary to place the girder on a transportation mechanism to detect the structure of the girder. During this period, it is necessary to lift and place the girder and unload the girder, which not only increases the workload of girder detection, affects the efficiency of girder detection, but also makes it possible for the girder to be damaged during the loading and unloading process, and increases the floor area occupied by the girder detection equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a detection tooling for a light truck girder to solve the problems in the above background art that it is necessary to place the girder on a transportation mechanism to detect the structure of the girder. During this period, it is necessary to lift and place the girder and unload the girder, which not only increases the workload of girder detection, affects the efficiency of girder detection, but also makes it possible for the girder to be damaged during the loading and unloading process, and increases the floor area occupied by the girder detection equipment.

[0006] To achieve the above object, the present invention provides the following technical solution: A detection tooling for the girder of a light truck, including two vertical seats and a lifting frame. The lifting frame is fixedly installed between the tops of the two vertical seats. An elevating plate is movably installed on the lifting frame, and a girder clamping assembly is fixedly installed at the bottom of the center of the elevating plate. A swing assembly is movably installed at the bottom of the girder clamping assembly, and a line laser scanning assembly is fixedly installed on the swing assembly. The swing assembly includes a pressure rod, a fixed end, a grinding disc, a motor, a fixing plate, a driving wheel, a swing rod, a vertical rod, a rotating shaft, and an eccentric rod. The outer side of the fixed end is fixedly installed at one end of the pressure rod, and the bottom of the fixed end is fixedly installed with the top of the grinding disc. The bottom of the line laser scanning assembly is fixedly installed with the top of the other end of the pressure rod. The outer side of the bottom of the motor is fixedly installed with the elevating plate through the fixing plate, and the driving wheel is installed at the output end of the motor. The eccentric rod is fixedly installed on one side of the bottom of the driving wheel. A slot is opened on the swing rod, and the bottom of the eccentric rod is movably inserted into the inner side of the slot. The pressure rod is rotatably installed at the bottom of the fixing plate through the rotating shaft. One end of the swing rod is fixedly installed with the top of the pressure rod through the vertical rod. A rotating end is rotatably inserted at the top of the pressure rod, and the top end of the rotating end is fixedly installed with the bottom of the girder clamping assembly. After placing the girder on the ground in the detection area of the factory, move the vertical seats and the lifting frame on their tops to the top of one end of the girder. By lowering the height of the lifting frame, the girder clamping assembly clamps on both sides of the girder during the gradual downward movement, so as to limit the displacement path of the device, so that when the device is pushed, it can move along the outer edge of the girder to scan the structure of the girder. During the pushing process, the motor of the swing assembly is started, and the eccentric rod of the driving wheel circulates in the slot of the swing rod, so that the swing rod drives the pressure rod to swing left and right in a cycle on the upper surface of the girder through the vertical rod while moving forward. The grinding disc at the front end of the swinging pressure rod wipes the rust and dirt on the upper surface of the girder, which is convenient for the subsequent line laser scanning assembly to accurately scan the structure of the girder. And when the line laser scanning assembly follows the left and right cyclic swing of the pressure rod, it can make the scanning work of the girder more complete and be applicable to the scanning detection work of girders with a larger width.

[0007] Preferably, the lifting frame includes two adapter plates and a hydraulic telescopic rod. Guide rails are fixedly installed on both of the two adapter plates, and a top plate is fixedly installed on the top of the guide rails. The outer side of the hydraulic telescopic rod is fixedly installed on the top plate, and the bottom of the hydraulic telescopic rod is fixedly installed with the top of one side of the elevating plate. Through the control of the hydraulic telescopic rod, the elevating plate can move up and down between the adapter plates and the top plate along the guide rails, so as to adjust the downward pressure height of the girder clamping assembly.

[0008] Preferably, a limiting rod is movably inserted into the other side of the elevating plate, and the limiting rod is fixedly installed between the adapter plates and the top plate. The limiting rod is used to limit the other side of the elevating plate with a changed height to prevent the problem of side deviation of the elevating plate during the lifting process.

[0009] Preferably, the two stands each include a base plate, a vertical plate, and a lifting plate, the vertical plate is fixedly installed between the base plate and the lifting plate, and the adapter plate is fixedly installed on the top of the lifting plate, the base plate, the vertical plate, and the lifting plate constitute the main structure of the stand, and the stand serves as the bottom support structure of the entire device.

[0010] Preferably, universal wheels are symmetrically mounted on the bottom of the base plate to facilitate displacement of the device along the edge path of the beam to perform complete scanning and detection work.

[0011] Preferably, the beam clamping assembly includes an outer shell, an insertion shaft, and a movable block. The movable block is movably inserted into the inner side of the outer shell, and the insertion shaft is fixedly inserted into the axis of the movable block. Connecting rod one is rotatably installed on both sides of the movable block, and connecting rod two is rotatably installed on both connecting rods one. When the height of the beam clamping assembly is lowered, the insertion shaft and the pressure rod at the bottom thereof are squeezed by the upper surface of the beam and pushed upward along the inner side of the outer shell, so that the movable block fixed on the outer side of the insertion shaft drives connecting rod two to rotate through connecting rod one.

[0012] Preferably, clamping blocks are rotatably installed on both of the two connecting rods, and balls are rotatably installed on the clamping blocks. When the connecting rods rotate, the two clamping blocks will be driven to squeeze inward, thereby clamping the outer side of the beam, and the balls will roll on the outer side of the beam when the device moves along the beam to reduce friction.

[0013] Preferably, a mounting groove is provided on the clamping block, and a laser scanner is fixedly installed inside the mounting groove.

[0014] Preferably, the bottom of the plug shaft is fixedly mounted on the top of the rotating end head, and the connecting rod three is rotatably mounted on the clamping block, and the connecting rod three is rotatably mounted on the housing.

[0015] Preferably, a detection slot is provided through one end of the pressure rod, and the line laser scanning assembly comprises a lifting frame, a card plate is fixedly mounted on the lifting frame, and a second laser scanner is fixedly mounted on the card plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, during the inspection process of the beam, there is no need to load and unload the beam. The device only needs to be clamped on the top of the beam. When the device is pushed to move along the edge of the beam, the beam structure can be quickly and comprehensively scanned and inspected. This not only reduces the workload of beam inspection and improves the inspection efficiency, but also does not require the beam to be lifted during the entire inspection process, thus avoiding the problem of beam damage.

[0018] 2. In the present invention, during the scanning and pushing process of the girder structure, the motor of the swinging assembly starts, and the eccentric rod of the driving wheel circulates within the slot of the swinging rod, causing the swinging rod to drive the pressing rod through the vertical rod to move forward while swinging left and right in a cycle on the upper surface of the girder. The grinding disc at the front end of the swinging pressing rod wipes off the rust and dirt on the upper surface of the girder, facilitating the subsequent precise scanning of the girder structure by the line laser scanning assembly. Moreover, when the line laser scanning assembly follows the left and right cyclic swinging of the pressing rod, the scanning work of the girder can be more complete, and it can be applied to the scanning and detection work of girders with a larger width.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figures 1-7Shown: A detection tooling for a light truck beam, including two vertical seats 1 and a lifting frame 2. The lifting frame 2 is fixedly installed between the tops of the two vertical seats 1. A lifting plate 3 is movably installed on the lifting frame 2, and a beam clamping assembly 4 is fixedly installed at the bottom of the center of the lifting plate 3. A swing assembly 5 is movably installed at the bottom of the beam clamping assembly 4, and a line laser scanning assembly 6 is fixedly installed on the swing assembly 5. The swing assembly 5 includes a pressure rod 50, a fixed end 51, a grinding disc 52, a motor 53, a fixing plate 54, a driving wheel 55, a swing rod 56, a vertical rod 57, a rotating shaft 58, and an eccentric rod 59. The outer side of the fixed end 51 is fixedly installed at one end of the pressure rod 50, and the bottom of the fixed end 51 is fixedly installed with the top of the grinding disc 52. The bottom of the line laser scanning assembly 6 is fixedly installed with the top of the other end of the pressure rod 50. The outer bottom of the motor 53 is fixedly installed with the lifting plate 3 through the fixing plate 54, and the driving wheel 55 is installed at the output end of the motor 53. The eccentric rod 59 is fixedly installed on one side of the bottom of the driving wheel 55. A slot 560 is opened on the swing rod 56, and the bottom of the eccentric rod 59 is movably inserted into the inner side of the slot 560. The pressure rod 50 is rotatably installed with the bottom of the fixing plate 54 through the rotating shaft 58. One end of the swing rod 56 is fixedly installed with the top of the pressure rod 50 through the vertical rod 57. A rotating end 410 is rotatably inserted at the top of the pressure rod 50, and the top of the rotating end 410 is fixedly installed with the bottom of the beam clamping assembly 4; After placing the beam on the ground in the detection area of the factory, move the vertical seat 1 and the lifting frame 2 on its top to the top of one end of the beam. By lowering the height of the lifting frame 2, the beam clamping assembly 4 is clamped on both sides of the beam during the gradual downward movement, so as to limit the displacement path of the device, so that when the device is pushed, it can move along the outer edge of the beam to scan the beam structure. During the pushing process, the motor 53 of the swing assembly 5 is started, and the eccentric rod 59 of the driving wheel 55 will move cyclically in the slot 560 of the swing rod 56, so that the swing rod 56 drives the pressure rod 50 on the upper surface of the beam through the vertical rod 57, swinging left and right in a cycle while moving forward. The grinding disc 52 at the front end of the swinging pressure rod 50 will wipe the rust and dirt on the upper surface of the beam, which is convenient for the subsequent line laser scanning assembly 6 to accurately scan the beam structure. And when the line laser scanning assembly 6 follows the left and right cyclic swing of the pressure rod 50, the scanning work of the beam can be more complete, and it can be applied to the scanning detection work of beams with a larger width.

[0030] According to Figure 1 and Figure 2As shown, the lifting frame 2 includes two adapter plates 20 and hydraulic telescopic rods 23. Guide rails 21 are fixedly installed on both of the two adapter plates 20, and a top plate 22 is fixedly installed at the top of the guide rails 21. The outside of the hydraulic telescopic rod 23 is fixedly installed on the top plate 22, and the bottom of the hydraulic telescopic rod 23 is fixedly installed with the top of one side of the lifting plate 3. The lifting plate 3 can move up and down between the adapter plate 20 and the top plate 22 along the guide rail 21 under the control of the hydraulic telescopic rod 23, so as to adjust the pressing height of the beam clamping assembly 4.

[0031] According to Figure 1 and Figure 2 As shown, a limiting rod 24 is movably inserted into the other side of the lifting plate 3, and the limiting rod 24 is fixedly installed between the adapter plate 20 and the top plate 22. The limiting rod 24 is used to limit the other side of the lifting plate 3 with changed height to prevent the problem of side deviation of the lifting plate 3 during the lifting process.

[0032] According to Figure 1 and Figure 2 As shown, both of the two upright seats 1 include a bottom plate 10, a vertical plate 11, and a lifting plate 12. The vertical plate 11 is fixedly installed between the bottom plate 10 and the lifting plate 12, and the adapter plate 20 is fixedly installed on the top of the lifting plate 12. The bottom plate 10, the vertical plate 11, and the lifting plate 12 constitute the main structure of the upright seat 1, and the upright seat 1 serves as the bottom support structure of the entire device.

[0033] According to Figure 2 As shown, universal wheels 13 are symmetrically installed at the bottom of the bottom plate 10, which is convenient for the device to move along the edge path of the beam to perform a complete scanning and detection work.

[0034] According to Figure 3 、 Figure 4 and Figure 5 As shown, the beam clamping assembly 4 includes a housing 40, an insertion shaft 41, and a movable block 42. The movable block 42 is movably inserted into the inside of the housing 40, and the insertion shaft 41 is fixedly inserted at the center of the movable block 42. Link rods one 43 are rotatably installed on both sides of the movable block 42, and link rods two 44 are rotatably installed on both of the two link rods one 43. When the height of the beam clamping assembly 4 drops, the insertion shaft 41 and the pressure rod 50 at its bottom are squeezed by the upper surface of the beam, and are pushed upward along the inside of the housing 40, so that the movable block 42 fixed to the outside of the insertion shaft 41 drives the link rod two 44 to rotate through the link rod one 43.

[0035] According to Figure 3 and Figure 4 As shown, clamping blocks 46 are rotatably installed on both of the two link rods two 44, and balls 47 are rotatably installed on the clamping blocks 46. When the link rod two 44 rotates, it will drive the two clamping blocks 46 to squeeze inward, so as to clamp the outside of the beam, and the balls 47 roll on the outside of the beam when the device moves along the beam to reduce the friction force.

[0036] According to Figure 3 As shown, a mounting groove 48 is formed on the clamping block 46, and a first laser scanner 49 is fixedly installed inside the mounting groove 48. The two first laser scanners 49 are respectively used for scanning and detecting the structures on both sides of the girder.

[0037] According to Figure 3 and Figure 4 As shown, the bottom of the insertion shaft 41 is fixedly installed with the top of the rotating end 410. A third connecting rod 45 is rotatably installed on the clamping block 46, and the third connecting rod 45 is rotatably installed with the housing 40. The third connecting rod 45 is used to enhance the structural strength of the girder clamping assembly 4.

[0038] According to Figure 5, a detection groove 501 is formed through one end of the pressure rod 50. The line laser scanning assembly 6 includes a lifting frame 60. A clamping plate 61 is fixedly installed on the lifting frame 60, and a second laser scanner 62 is fixedly installed on the clamping plate 61. The clamping plate 61 and the second laser scanner 62 fixed thereon are adjusted in height inside the lifting frame 60. The second laser scanner 62 detects the structure on the upper surface of the girder through the detection groove 501.

[0039] Usage method and working principle of this device: After placing the girder on the ground in the detection area of the factory, move the upright seat 1 and the lifting frame 2 on its top to the top of one end of the girder. The lifting plate 3 can be displaced up and down between the adapter plate 20 and the top plate 22 along the guide rail 21 under the control of the hydraulic telescopic rod 23, so as to adjust the pressing height of the girder clamping assembly 4. By lowering the height of the lifting frame 2, when the girder clamping assembly 4 gradually moves downward, when the height of the girder clamping assembly 4 decreases, the insertion shaft 41 and the pressure rod 50 at its bottom are squeezed by the upper surface of the girder and pushed upward along the inside of the housing 40, so that the movable block 42 fixed on the outside of the insertion shaft 41 drives the second connecting rod 44 to rotate through the first connecting rod 43. When the second connecting rod 44 rotates, it will drive the two clamping blocks 46 to squeeze inward, so as to clamp the outside of the girder, and the ball 47 rolls on the outside of the girder when the device moves along the girder to reduce the friction force.

[0040] The main beam clamping assembly 4 defines the displacement path of the device, so that when the device is pushed, it can displace along the outer edge of the main beam to scan the main beam structure. During the pushing process, the motor 53 of the swing assembly 5 is started, and the eccentric rod 59 of the driving wheel 55 circulates in the slot 560 of the swing rod 56, so that the swing rod 56 drives the pressing rod 50 on the upper surface of the main beam through the vertical rod 57, and swings left and right in a cycle while advancing. The grinding disc 52 at the front end of the swinging pressing rod 50 wipes the rust and dirt on the upper surface of the main beam, facilitating the subsequent precise scanning of the main beam structure by the line laser scanning assembly 6. When the line laser scanning assembly 6 follows the left and right cyclic swing of the pressing rod 50, the scanning work of the main beam can be more complete, and it can be applied to the scanning and detection work of main beams with a larger width.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
