[0026] Figure 6 for Figure 4 Enlarged view of point D. Detailed Implementation
[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0028] like Figures 1-6 As shown, a mobile gantry for debris penetration performance testing includes a gantry 1. The gantry 1 includes a crossbeam 11 arranged at the top and support frames arranged at the left and right ends of the crossbeam 11. The support frames are used to support the crossbeam 11. As one option, the crossbeam 11 is I-shaped. To facilitate the transfer of the gantry 1, in this embodiment, casters 12 are installed at the bottom of both the left and right sides of the gantry 1, such as at least two casters 12 on each side.
[0029] In this embodiment, a movable component 3 is slidably connected to the crossbeam frame 11. The movable component 3 includes a main body slidably connected to the crossbeam frame 11 and several first linear bearings arranged on the left and right sides of the main body. The main body can be a square component adapted to the shape of the crossbeam frame 11, with a hollow center to allow the crossbeam frame 11 to pass through. The state of the main body after being arranged on the crossbeam frame 11 is as follows. Figure 1 , Figure 2 As shown.
[0030] In one embodiment, the left side of the main body has two first linear bearings arranged vertically, and the right side of the main body has two first linear bearings arranged vertically, with the holes of the two first linear bearings on the same side corresponding longitudinally.
[0031] In this embodiment, a slide motor 13 is installed at the bottom of the crossbeam frame 1, and a winch 14 is installed on the slide motor 13. The winch 14 moves laterally within the length range of the slide motor 13.
[0032] The winch 14 includes a pull rope 15 wound around its inner cavity. The outer end of the pull rope 15 is connected to a connecting device 2. In order to facilitate the movement of the pull rope 15, in this embodiment, a first connecting frame 18 for mounting the first pulley 16 is provided on the winch 14, and a second connecting frame 19 for mounting the second pulley 17 is provided on the moving component 3. The pull rope 15 is wound around the first pulley 16 and the second pulley 17.
[0033] In one embodiment, one end of the pull rope 15 is equipped with a second connecting ring 20, which is connected to a first connecting ring 21 disposed on the connecting device.
[0034] The connecting device 2 is equipped with corresponding second linear bearings on its left and right sides respectively. The second linear bearings correspond to the first linear bearings in the longitudinal direction. That is, the left and right sides of the crossbeam frame 11 are equipped with the first linear bearing, the first linear bearing and the second linear bearing from top to bottom.
[0035] The first and second linear bearings are used to pass through the guide rods 31. As shown in the figure, corresponding guide rods 31 are arranged on the left and right sides of the crossbeam frame 11, respectively. The lower ends of the two guide rods 31 are connected to an impact hammer head 23. The impact hammer head 23 and the guide rods 31 constitute a penetrating device.
[0036] Furthermore, one end of the pull rope 15 is equipped with a second connecting ring 20, and the connecting device 2 is equipped with a first connecting ring 22 that cooperates with the second connecting ring 20. An electromagnet 22 is connected below the first connecting ring 22. The electromagnet 22 is used to magnetically attract the impact hammer head 23. The lower part of the impact hammer head 23 is used to install the impact wooden rod 24. The impact wooden rod 24 of different lengths can be selected according to actual needs.
[0037] The connecting device 2 is also equipped with an electromagnetic lock. If a hook-like component is installed on the upper part of the impact hammer, the hook-like component can be hung on the electromagnetic lock to ensure that the impact hammer will not fall and injure people when the equipment is powered off. Of course, the electromagnetic lock is optional, and not installing the electromagnetic lock will not affect normal testing.
[0038] The linear bearing and guide rod mentioned above is one implementation method. In this embodiment, first connecting holes can be directly opened on both sides of the connecting device 2, and second connecting holes can be opened on both sides of the moving component 3. The center hole of the first connecting hole is aligned with the center hole of the second connecting hole. The connecting device 2 is connected to the guide rod 31 through the first connecting holes on both sides. The guide rod 31 is in contact with the base plate of the connecting device 2. The moving component 3 is connected to the guide rod 31 through the second connecting holes on both sides.
[0039] The tops of the two guide rods 31 are connected to connectors, and dampers 32 are installed on the connectors. The dampers 32 are arranged directly above the crossbeam frame and are used to protect the relevant structures from colliding with the crossbeam frame 11 when the impact hammer penetrates the workpiece to be tested.
[0040] The operator can control the descent or ascent of the impact hammer head through the winch 14 and the slide table motor. When the impact hammer head is in the descent state, the guide rod 31 descends synchronously. When the impact hammer head is in the ascent state, the guide rod 31 rises synchronously. The guide rod 31 also ensures that the impact hammer head vertically impacts the point to be measured.
[0041] As one implementation method, a compatible PLC host, i.e., an intelligent control system, can also be configured. Operators operate this utility model through the intelligent control system. Of course, this is optional, and not setting it will not affect normal testing.
[0042] After determining the test position of the penetration device, the impact hammer is lowered by the winch 14. Once the impact wooden rod 24 can contact the test point of the test workpiece, the impact hammer is raised to the specified test height by the linear motor.
[0043] After this step is completed, the operator controls the electromagnet 22 to be de-energized, and the impact hammer falls to complete the penetration performance test on the test workpiece.
[0044] One of the test conditions is as follows: a 36kg impact hammer is dropped vertically free from a height of 1 meter above the test point. If the test point is not damaged after being impacted by the impacting wooden stick, the test is considered qualified.
[0045] The impact hammer head may include a counterweight to increase the overall weight or to precisely adjust the overall weight of the impact hammer head by adjusting the counterweight.
[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
