Description

Technical Field

[0001] This utility model relates to the field of aerospace test specimen loading technology, specifically to a test specimen loading device. Background Technology

[0002] Aerospace refers to the navigation activities of aircraft within the Earth's atmosphere and the navigation activities of aircraft in outer space. The development of aviation has significantly changed the structure of transportation. Aircraft contain numerous rods and short beams, which require loading tests before being put into use.

[0003] Currently, existing test members such as rods and short beams lack protective devices during loading tests. When the test member breaks during the loading test, some debris is generated. This debris has a large kinetic energy when the test member breaks and is easy to fly, causing injury to the operators observing nearby. Utility Model Content

[0004] The purpose of this invention is to provide a test specimen loading device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a test specimen loading device, comprising:

[0006] The base plate has a bearing seat fixed on both the left and right sides of its upper side. A first hydraulic cylinder is installed on the bearing seat. The telescopic end of the first hydraulic cylinder is connected to an L-shaped connector. The L-shaped connector is slidably connected to the bearing seat.

[0007] Two supporting sidewalls are fixed to the upper left and right ends of the base plate, respectively. A second hydraulic cylinder is fixed to the top of each of the two supporting sidewalls. The telescopic ends of the two second hydraulic cylinders are connected to a lifting plate base. Transparent protective plates are fixed to the lower front and rear edges of the lifting plate base. A third hydraulic cylinder is installed in the upper middle part of the lifting plate base. The telescopic end of the third hydraulic cylinder slides through the lifting plate base and is connected to a pressing seat.

[0008] Preferably, the transparent protective plate is made of high-strength transparent glass, which facilitates observation while providing protection.

[0009] Preferably, a slide rail is fixed on the bearing seat, and a slide block is fixed at the bottom of the L-shaped connector. The slide block is slidably mounted on the slide rail to improve the stability of the L-shaped connector installation.

[0010] Preferably, the distance between the two transparent protective plates is greater than the width of the support seat, so that the two transparent protective plates can cover the support seat.

[0011] Preferably, a buffer pad is fixed to the bottom of the transparent protective plate to provide a buffering effect and reduce the impact when the transparent protective plate comes into contact with the base plate.

[0012] Preferably, the L-shaped connector has multiple connection holes.

[0013] Preferably, the pressing seat is located between the front and rear transparent protective plates.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By fixing transparent protective plates on the lower front and rear edges of the lifting plate seat, when the second hydraulic cylinder pushes the lifting plate seat down, the two transparent protective plates move down to surround the bearing seat and the test piece. The two transparent protective plates can block the debris generated when the test piece breaks, and prevent the debris from causing damage to the surrounding observers.

[0016] 2. The test piece is equipped with a first hydraulic cylinder, an L-shaped connector, a third hydraulic cylinder, and a pressing seat. Both ends of the test piece are connected to the two L-shaped connectors. The two first hydraulic cylinders can apply tensile load to the test piece when they work. At the same time, the third hydraulic cylinder pushes the pressing seat downward, so that the pressing seat presses the test piece and applies downward pressure to the test piece. The operation is simple and meets the requirements. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 4 The test specimen loading device shown includes:

[0026] The base plate 1 has a bearing seat 2 fixed on both the left and right sides of the upper side. A first hydraulic cylinder 3 is installed on the bearing seat 2. The telescopic end of the first hydraulic cylinder 3 is connected to an L-shaped connector 4. The L-shaped connector 4 is slidably connected to the bearing seat 2.

[0027] Two supporting sidewalls 5 are fixed to the upper left and right ends of the base plate 1, respectively. A second hydraulic cylinder 6 is fixed to the top of each of the two supporting sidewalls 5. The telescopic ends of the two second hydraulic cylinders 6 are connected to the lifting plate base 7. Transparent protective plates 8 are fixed to the lower front and rear edges of the lifting plate base 7. A third hydraulic cylinder 9 is installed in the middle of the upper side of the lifting plate base 7. The telescopic end of the third hydraulic cylinder 9 slides through the lifting plate base 7 and is connected to the pressing seat 10.

[0028] The transparent protective panel 8 is made of high-strength transparent glass, which facilitates observation while providing protection.

[0029] A slide rail 11 is fixed on the bearing seat 2, and a slide block 12 is fixed on the bottom of the L-shaped connector 4. The slide block 12 is slidably installed on the slide rail 11 to improve the stability of the L-shaped connector 4 installation.

[0030] The distance between the two transparent protective plates 8 is greater than the width of the support seat 2, so that the two transparent protective plates 8 can cover the support seat 2.

[0031] A buffer pad 13 is fixed to the bottom of the transparent protective plate 8 to provide a buffering effect and reduce the impact when the transparent protective plate 8 comes into contact with the base plate 1.

[0032] The L-shaped connector 4 has multiple connection holes 14.

[0033] The pressing seat 10 is located between the front and rear transparent protective plates 8.

[0034] In this invention, the test piece is placed between two L-shaped connectors 4, with both ends of the test piece connected to the two L-shaped connectors 4. When the loading experiment begins, the two second hydraulic cylinders 6 work together to push the lifting plate seat 7 downward. The downward movement of the lifting plate seat 7 causes the two transparent protective plates 8 at its bottom to move downward, so that the buffer pads 13 at the bottom of the two transparent protective plates 8 contact the base plate seat 1. The two transparent protective plates 8 sandwich the bearing seat 2 and the test piece in the middle. The transparent protective plates 8 are made of high-strength transparent glass, which is convenient for observation and can also block the debris generated when the test piece breaks, preventing the debris from causing injury to the surrounding observers. The two first hydraulic cylinders 3 work to apply tensile load to the test piece. At the same time, the third hydraulic cylinder 9 works to push the pressing seat 10 downward, so that the pressing seat 10 presses the test piece and applies downward pressure to the test piece. The operation is simple and meets the requirements.
