[0002] Damper testing machines are essential equipment for testing the damping performance of materials, components, or systems under dynamic loading conditions. In the fields of structural dynamics and materials science, damping performance is a crucial parameter for measuring the energy dissipation capacity of materials or structures under dynamic loads such as vibration and impact. Therefore, the design and manufacture of damper testing machines are of great significance for ensuring the safety and stability of various engineering structures.

[0003] CN20202005912.5 is a novel patent in China that discloses a mechanism for adjusting and eliminating backlash in the moving crossbeam of a damper testing machine (authorization announcement number CN211904866U). This patented technology can achieve stepped adjustment of the test space with an adjustment interval of 500mm, which facilitates the adjustment of the test space. However, it slows down the positioning and testing of the sample, reducing the testing efficiency and flexibility.

[0004] Therefore, this application provides a moving crossbeam for a damper testing machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a moving crossbeam for a damper testing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The main frame has a movable crossbeam at its outer end. Multiple evenly distributed pin holes are drilled at one end of the main frame near the movable crossbeam. A connecting beam is fixedly connected to the left end of the movable crossbeam, and a sample mounting plate is located at the left end of the connecting beam. A support platform is fixedly connected to the upper end of the movable crossbeam, and a mounting plate is fixedly connected to the upper end of the support platform. Two symmetrical clamping cylinders are mounted on the mounting plate, and frame clamps are fixedly connected to the output ends of the clamping cylinders. The two frame clamps are located on the outer sides of the main frame and the movable crossbeam, respectively. Four evenly distributed connecting feet are fixedly connected to the outer end of the movable crossbeam, and rollers are rotatably connected to the upper ends of the connecting feet. The rollers are located on the outer side of the main frame and in contact with it. A pin-mounted cylinder is embedded within the movable crossbeam, and pins are fixedly connected to both power output ends of the pin-mounted cylinder. A geared motor is fixedly connected to the bottom end of the movable crossbeam, and a rack is fixedly connected to the outer end of the main frame. The output end of the geared motor meshes with the rack, enabling rapid sample positioning and testing, greatly improving testing efficiency and flexibility. This design can also adapt to samples of different sizes, meeting various testing needs.

[0008] As a further embodiment of this utility model: an electrical control box is fixedly connected to the bottom end of the movable crossbeam, and a warning light is installed on the outer end of the electrical control box. The electrical control box is electrically connected to the pin cylinder and the reduction motor. By observing the warning light, when the green light of the warning light is on, it indicates that the pin is in place and the movable crossbeam can move. When the red light is on, it indicates that the pin is locked and the movable crossbeam cannot move.

[0009] As a further embodiment of this utility model: a load sensor is fixedly connected between the connecting beam and the sample mounting connecting plate. The load sensor includes a connecting disc with multiple evenly distributed mounting holes drilled at the outer end of the connecting disc. The sensor body is mounted on the outer end of the connecting disc. The load sensor can be installed between the connecting beam and the sample mounting connecting plate through the connecting disc. At the same time, it can also facilitate the collection of load data of the sample mounted on the sample mounting connecting plate and transmit it to the warning light.

[0010] As a further improvement of this utility model, each of the two frame clamps is fixedly connected to a connecting block at one end close to the other, and a contact pad is fixedly connected to the outer end of the connecting block. By setting the connecting block and the contact pad, the possibility of damage to the main frame and the moving crossbeam can be reduced when the clamp cylinder retracts.

[0011] As a further improvement of this utility model, the bottom end of the frame clamp is fixedly connected to a bearing plate, which is located at the upper end of the support platform and slidably connected to the support platform. By setting the bearing plate, the frame clamp can be supported, making the horizontal direction of the frame clamp more stable.

[0012] As a further improvement of this utility model, a square groove is chiseled at the upper end of the frame clamp. By setting the square groove, technicians can easily remove the frame clamp from the output end of the clamp cylinder, thereby facilitating the regular maintenance and replacement of the frame clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device, by adopting a movable crossbeam design, enables rapid positioning and testing of samples, greatly improving testing efficiency and flexibility. At the same time, this design can also adapt to samples of different sizes to meet different testing needs.

[0015] 2. This device achieves stable control and position locking of the moving crossbeam by using a clamping cylinder and a pin mechanism. The clamping cylinder holds the main frame and the moving crossbeam tightly to form a stable support structure, effectively preventing the moving crossbeam from shaking and shifting during the test. The pin mechanism ensures that the moving crossbeam is accurately locked in the designated position, thereby guaranteeing the stability and accuracy of the test.

[0016] 3. The device features a square slot, which allows technicians to easily remove the frame clamp from the output end of the clamp cylinder, facilitating regular maintenance and replacement of the frame clamp. This design not only improves the reliability and stability of the equipment but also reduces maintenance difficulty and cost. Attached Figure Description

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] Please see Figures 1-4A damper testing machine with a moving crossbeam includes a main frame 1, a moving crossbeam body 2 at the outer end of the main frame 1, and multiple evenly distributed pin holes 3 at the end of the main frame 1 near the moving crossbeam body 2. A connecting beam 4 is fixedly connected to the left end of the moving crossbeam body 2, and a sample mounting connecting plate 5 is provided at the left end of the connecting beam 4. A support platform 6 is fixedly connected to the upper end of the moving crossbeam body 2, and a mounting plate 7 is fixedly connected to the upper end of the support platform 6. Two symmetrical clamping cylinders 8 are mounted on the mounting plate 7, and frame clamps 9 are fixedly connected to the output ends of the clamping cylinders 8. 9 are located on the outside of the main frame 1 and the movable crossbeam 2 respectively. Four evenly distributed connecting feet 10 are fixedly connected to the outer end of the movable crossbeam 2. Rollers 11 are rotatably connected to the upper end of the connecting feet 10. The rollers 11 are located on the outside of the main frame 1 and are in contact with the main frame 1. A pin cylinder 12 is embedded in the movable crossbeam 2. Pins 13 are fixedly connected to both power output ends of the pin cylinder 12. A geared motor 14 is fixedly connected to the bottom end of the movable crossbeam 2. A rack 15 is fixedly connected to the outer end of the main frame 1. The output end of the geared motor 14 meshes with the rack 15.

[0025] Please see Figure 3 An electrical control box 201 is fixedly connected to the bottom of the movable crossbeam 2. In actual use, the electrical control box 201 can be equipped with a hand control box. The hand control box is connected to the electrical control box 201 to control the start and stop of the movement of the movable crossbeam. A warning light 202 is installed on the outer end of the electrical control box 201. The electrical control box 201 is electrically connected to the pin cylinder 12 and the reduction motor 14. By observing the warning light 202, when the green light of the warning light 202 is on, it indicates that the pin 13 is in place and the movable crossbeam can move. When the red light is on, it means that the pin 13 is locked and the movable crossbeam cannot move.

[0026] Please see Figure 4 A load sensor 401 is fixedly connected between the connecting beam 4 and the sample mounting connecting plate 5. The load sensor 401 includes a connecting disc 402. Multiple evenly distributed mounting holes 403 are drilled on the outer end of the connecting disc 402. A sensor body 404 is installed on the outer end of the connecting disc 402. The load sensor 401 can be installed between the connecting beam 4 and the sample mounting connecting plate 5 through the connecting disc 402. At the same time, it can also facilitate the collection of load data of the sample mounted on the sample mounting connecting plate 5 and transmit it to the warning light 202.

[0027] Please see Figure 2Two frame clamps 9 are fixedly connected to each other at their close ends with connecting blocks 901. Contact pads 902 are fixedly connected to the outer ends of the connecting blocks 901. By setting the connecting blocks 901 and contact pads 902, the possibility of damage to the main frame 1 and the moving crossbeam 2 when the clamp cylinder 8 retracts can be reduced. A bearing plate 903 is fixedly connected to the bottom end of the frame clamp 9. The bearing plate 903 is located on the upper end of the support platform 6 and is slidably connected to the support platform 6. By setting the bearing plate 903, the frame clamp 9 can be supported, making the frame clamp 9 more stable in the horizontal direction. A square groove 904 is chiseled at the upper end of the frame clamp 9. By setting the square groove 904, technicians can easily remove the frame clamp 9 from the output end of the clamp cylinder 8, thereby facilitating the regular maintenance and replacement of the frame clamp 9.

[0028] Working principle: Activating the clamping cylinder 8 causes its power output end to retract, driving the frame clamp 9 to clamp the main frame 1, making the main frame 1 less prone to deformation. Activating the reduction motor 14 causes its power output end to rotate, thereby using the meshing action of the reduction motor 14 and rack 15 to move the moving crossbeam 2 along the main frame 1. Controlling the pin cylinder 12 causes it to push the pin 13 into the insertion pin hole 3, thus locking the position of the moving crossbeam. After the sample is installed on the sample mounting connecting plate 5, controlling the pin cylinder 12 to retract the pin 13 allows the damper test to be performed on the sample.
