Description

Technical Field

[0001] The utility model relates to the field of support beams, and specifically relates to a device for detecting the strength of a support beam. Background Technique

[0002] A support beam is a component that undertakes the functions of support and structural strength in new energy vehicles. It is usually made of lightweight materials such as aluminum alloy or carbon fiber composite materials. The design and manufacture of the support beam need to ensure sufficient strength and stiffness to ensure the safety and stability of the vehicle during driving. Therefore, during the use of the support beam, it is necessary to detect its strength, and the stress condition is evaluated by measuring the deformation of the material.

[0003] Currently, when installing strain gauges on the surface of a support beam, it is usually necessary to fix them with sealant. However, since the sealant needs to be applied repeatedly, and the strain gauge is small in volume, and the operator usually holds the power cord of the strain gauge, when the strain gauge is placed on the surface of the support beam and the sealant is applied repeatedly, the strain gauge will move under the external force during application, resulting in inconvenience in applying the sealant. Therefore, a device for detecting the strength of a support beam is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and avoid the inconvenience of applying sealant, the utility model proposes a device for detecting the strength of a support beam.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a device for detecting the strength of a support beam, including a "U"-shaped plate; a support plate is fixedly installed at the top end of the "U"-shaped plate, a limiting component is arranged on the top of the support plate, a coating component is arranged inside the limiting component, and a fixing component is arranged inside the "U"-shaped plate;

[0006] The limiting component includes an internally threaded sleeve fixedly installed on the top wall of the support plate. A threaded rod is threadedly connected inside the internally threaded sleeve. Fixing sleeves are fixedly installed on the front and rear sides of the bottom end of the threaded rod. A sliding rod is slidably connected inside the fixing sleeve. A pressure spring is fixedly installed at one end of the fixing sleeve close to the threaded rod. An abutting plate is fixedly installed at one end of the sliding rod close to the threaded rod.

[0007] Preferably, the top end of the threaded rod penetrates through the support plate and extends above the support plate. A circular handle is fixedly installed at the top end of the threaded rod. The operator can rotate the circular handle to drive the threaded rod to rotate. At this time, the threaded rod rotates inside the internally threaded sleeve and moves downward at the same time. One end of the pressure spring close to the threaded rod is fixedly installed on the end face of the abutting plate close to the sliding rod. The two abutting plates are pushed in the direction close to the threaded rod under the elastic force of the pressure spring. At this time, the two abutting plates limit the strain gauge.

[0008] Preferably, the smearing component includes an empty slot opened inside the bottom of the threaded rod. A rotating rod is rotatably connected to the top wall of the empty slot. A smearing block is fixedly connected to the bottom end of the rotating rod. A driven gear is fixedly installed on the surface of the top of the rotating rod. A driving gear is rotatably connected inside the threaded rod.

[0009] Preferably, the bottom end of the smearing block extends below the threaded rod. A notch is opened on the surface of the threaded rod. The notch communicates with the driven gear. The driving gear and the driven gear are meshed and connected. The driving gear extends outside the threaded rod. An operator can rotate the driving gear outside the threaded rod. At this time, the driving gear drives the meshed driven gear to rotate, and then drives the smearing block to rotate.

[0010] Preferably, the fixing component includes cavities opened inside the left and right sides of the "U"-shaped plate. Hollow blocks are fixedly installed on the front and rear sides inside the cavities. A solid block is slidably connected inside the hollow block close to the outside of the "U"-shaped plate. A fixing block is fixedly installed at one end of the solid block close to the outside of the "U"-shaped plate. A rolling roller is rotatably connected inside the fixing block close to one side of the "U"-shaped plate. A hexagonal convex block is fixedly installed in the middle of the bottom wall of the cavity. A rotating rod is rotatably connected to the top of the cavity where the "U"-shaped plate is located. A hexagonal groove is opened at the top end of the rotating rod. A connecting line is wound and connected to the surface of the rotating rod.

[0011] Preferably, the hexagonal convex block and the hexagonal groove are adaptively clamped. The top end of the rotating rod extends above the top wall of the "U"-shaped plate. One end of the connecting line away from the rotating rod is fixedly connected to the top of the solid block. The rotating rod can be rotated to wind the connecting line. At this time, the connecting line will pull the solid block and the fixing block to move, so that the two fixing blocks abut against the surface of the support beam, thereby limiting the position of the "U"-shaped plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The present utility model limits the position of the "U"-shaped plate by the two fixing blocks on the left and right sides abutting against the left and right sides of the support beam, so as to facilitate the rotation of the threaded rod on the surface of the "U"-shaped plate, thereby conveniently operating the threaded rod to facilitate smearing the sealing glue on the surface of the strain gauge;

[0014] An operator can limit the strain gauge by the two abutting plates. At this time, the strain gauge is stably limited on the surface of the support beam. After that, the strain gauge will not move during the process of smearing the sealing glue, thereby improving the efficiency of smearing the sealing glue. Description of the Drawings

[0025] The following will further describe the present application in detail in conjunction with the attached Figure 1 —7

[0026] An embodiment of the present application discloses a support beam strength detection device. Refer to Figure 1 , a support beam strength detection device, including a "U"-shaped plate 1; a support plate 2 is fixedly installed at the top of the "U"-shaped plate 1, a limiting component 3 is arranged on the top of the support plate 2, a coating component 4 is arranged inside the limiting component 3, and a fixing component 5 is arranged inside the "U"-shaped plate 1;

[0027] Refer to Figure 1 - Figure 3 , the limiting component 3 includes an internal thread sleeve 31 fixedly installed on the top wall of the support plate 2, a threaded rod 32 is threadedly connected inside the internal thread sleeve 31, fixing sleeves 33 are fixedly installed on both the front and rear sides of the bottom end of the threaded rod 32, a sliding rod 34 is slidably connected inside the fixing sleeve 33, a compression spring 35 is fixedly installed at one end of the fixing sleeve 33 close to the threaded rod 32, a contact plate 36 is fixedly installed at one end of the sliding rod 34 close to the threaded rod 32, the top end of the threaded rod 32 penetrates through the support plate 2 and extends above the support plate 2, a circular handle is fixedly installed at the top end of the threaded rod 32, an operator can rotate the circular handle to drive the threaded rod 32 to rotate. At this time, while the threaded rod 32 rotates inside the internal thread sleeve 31, it moves downward. One end of the compression spring 35 close to the threaded rod 32 is fixedly installed on the end face of the contact plate 36 close to the sliding rod 34. The two contact plates 36 are pushed in the direction close to the threaded rod 32 under the action of the elastic force of the compression spring 35. At this time, the two contact plates 36 limit the strain gauges.

[0028] Refer to Figure 4 , the coating component 4 includes an empty groove 41 opened inside the bottom of the threaded rod 32, a rotating rod 42 is rotatably connected to the top wall of the empty groove 41, a coating block 43 is fixedly connected to the bottom end of the rotating rod 42, a driven gear 44 is fixedly installed on the surface of the top of the rotating rod 42, a driving gear 45 is rotatably connected inside the threaded rod 32, the bottom end of the coating block 43 extends below the threaded rod 32, a notch is opened on the surface of the threaded rod 32, and the notch communicates with the driven gear 44. The driving gear 45 and the driven gear 44 are meshed and connected. The driving gear 45 extends outside the threaded rod 32. An operator can rotate the driving gear 45 outside the threaded rod 32. At this time, the driving gear 45 drives the meshed driven gear 44 to rotate, and then drives the coating block 43 to rotate.

[0029] Refer to Figure 5 - Figure 7, the fixing component 5 includes cavities 51 opened inside the left and right sides of the "return" shaped plate 1. Hollow blocks 52 are fixedly installed on the front and rear sides inside the cavity 51. A solid block 53 is slidably connected inside the hollow block 52 on the side close to the outside of the "return" shaped plate 1. A fixing block 54 is fixedly installed at one end of the solid block 53 close to the outside of the "return" shaped plate 1. A rolling roller 55 is rotatably connected inside the fixing block 54 on the side close to the "return" shaped plate 1. A hexagonal convex block 56 is fixedly installed in the middle of the bottom wall of the cavity 51. A rotating rod 57 is rotatably connected to the top of the "return" shaped plate 1 at the cavity 51. A hexagonal groove 58 is opened at the top end of the rotating rod 57. A connecting line 59 is wound and connected to the surface of the rotating rod 57. The hexagonal convex block 56 and the hexagonal groove 58 are adapted and clamped. The top end of the rotating rod 57 extends above the top wall of the "return" shaped plate 1. One end of the connecting line 59 away from the rotating rod 57 is fixedly connected to the top of the solid block 53. The rotating rod 57 can be rotated to wind the connecting line 59. At this time, the connecting line 59 will pull the solid block 53 and the fixing block 54 to move, so that the two fixing blocks 54 abut against the surface of the support beam, thereby limiting the position of the "return" shaped plate 1.

[0030] Working principle: After the operator wipes the surface of the support beam clean, then place the "return" shaped plate 1 on the top of the support beam, and at this time the center of the "return" shaped plate 1 is directly above the wiped part of the support beam. Then the operator pulls up the rotating rod 57 to make the hexagonal convex block 56 disengage from the hexagonal groove 58. Then the operator rotates the rotating rod 57. At this time, the rotating rod 57 will wind the connecting line 59, and the connecting line 59 will pull the solid block 53 to move into the hollow block 52. At this time, the solid block 53 will drive the fixed fixing block 54 to move. At this time, the fixing block 54 moves towards the side wall of the support beam. The positions of the left and right fixing blocks 54 are limited on the surface of the support beam, thereby limiting the position of the "return" shaped plate 1. And if it is necessary to adjust the position of the "return" shaped plate 1, the operator can push the "return" shaped plate 1. At this time, when the thrust received by the "return" shaped plate 1 is greater than the friction between the rolling roller 55 and the support beam, the "return" shaped plate 1 is pushed and moves;

[0031] After that, the operator applies the sealant to the bottom end of the application block 43, and then rotates the threaded rod 32. At this time, the threaded rod 32 rotates and moves downward inside the internal thread sleeve 31, so that the bottom end of the threaded rod 32 moves towards the position close to the support beam. Then, the operator simultaneously pulls the two sliding rods 34 to drive the abutting plate 36 to compress the compression spring 35, and places the strain gauge on the top of the support beam, and makes the strain gauge located directly below the application block 43. Then, the operator releases the sliding rod 34. At this time, the sliding rod 34 abuts against the surface of the strain gauge under the action of the resilience of the compression spring 35, so that the side wall of the strain gauge is defined by the two abutting plates 36. At this time, the operator rotates the driving gear 45, and the driving gear 45 will drive the engaged driven gear 44 to rotate, and the driven gear 44 will drive the fixed rotating rod 42 to rotate. At this time, the rotating rod 42 drives the application block 43 to rotate on the top of the strain gauge. At this time, the application block 43 can apply the sealant to the top of the strain gauge, and due to the limitation of the abutting plate 36, the strain gauge will not shift.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
