Description

Technical Field

[0001] The utility model relates to the technical field of pressure test equipment, in particular to an upper-mounted oil cylinder pressure testing machine. Background Art

[0002] The upper-mounted oil cylinder pressure testing machine is a device used to test and evaluate the strength and stability of long column materials and structures. The upper-mounted oil cylinder pressure testing machine applies pushing and pulling forces to load the long column and measures parameters such as its deformation, displacement, and stress under different loads.

[0003] There is no shielding mechanism on the existing upper-mounted oil cylinder pressure testing machine. Therefore, during the test process, it is impossible to protect against the fragments generated when an object breaks, which reduces the safety of the testing machine. Now, an upper-mounted oil cylinder pressure testing machine is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an upper-mounted oil cylinder pressure testing machine to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An upper-mounted oil cylinder pressure testing machine includes a base. A storage groove is opened on the base. A limiting plate is slidably connected inside the storage groove. A fixing component is arranged on the limiting plate and the storage groove. A protective plate is fixedly connected to the upper surface of the limiting plate. First springs are symmetrically and fixedly connected inside the protective plate.

[0007] A further improvement of the technical solution of the utility model is that one end of the first spring is fixedly connected to a flexible baffle. A connecting plate is fixedly connected to one side of the flexible baffle. A fixing bolt is threadedly connected inside the connecting plate. When the fixing bolt is unscrewed, the pulling force received by the first spring disappears, and the flexible baffle is driven into the protective plate for storage.

[0008] A further improvement of the technical solution of the utility model is that the fixing component includes a rubber clamping block. The rubber clamping block is fixedly connected to the limiting plate. A second spring is fixedly connected to the limiting plate. When the pressure received by the second spring decreases, the rubber clamping block is pushed into the positioning groove, improving the fit between the rubber clamping block and the positioning groove.

[0009] A further improvement of the technical solution of the utility model is that one end of the second spring is fixedly connected inside the rubber clamping block. A positioning groove is opened on the base. Ventilation holes are opened on the rubber clamping block. The rubber clamping block is movably connected inside the positioning groove. When the rubber clamping block is squeezed, the air inside it is discharged out through the ventilation holes.

[0010] A further improvement of the technical solution of the present utility model lies in that: a support frame is fixedly connected to the base, a lifting assembly is arranged inside the support frame, a first electric gripper is arranged on the lifting assembly, and a second electric gripper is arranged on the base. Starting the lifting assembly drives the first electric gripper to move up and down, thereby generating pressure and tension on one end of the object, and then completing the test.

[0011] A further improvement of the technical solution of the present utility model lies in that: a buffer plate is arranged on one side of the second electric gripper, a hollow rod is fixedly connected inside the second electric gripper, a rubber ball is fixedly connected inside the hollow rod, the connecting rod and the push plate are pushed into the hollow rod, squeezing the rubber ball, and can buffer the impact force.

[0012] A further improvement of the technical solution of the present utility model lies in that: a push plate is slidably connected inside the hollow rod, a connecting rod is fixedly connected to one side of the push plate, one end of the connecting rod is fixedly connected to the buffer plate, the connecting rod and the push plate are pushed into the hollow rod, squeezing the air inside the hollow rod, increasing the pressure inside the hollow rod, and can reduce the impact force generated during clamping.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0014] 1. The present utility model provides an upper-mounted oil cylinder pressure testing machine. Pull up the protective plate, driving the limit plate to move up synchronously, so that the rubber clamping block enters the positioning groove, and the second spring pushes the rubber clamping block into the positioning groove, improving the fit between the rubber clamping block and the positioning groove, thereby fixing the positions of the limit plate and the protective plate. Subsequently, pull out the two flexible baffles outward, stretching the first spring at the same time, making the two connecting plates stick together, and then use fixing bolts to connect the two, thereby fixing the positions of the two flexible baffles. Cooperating with the protective plate, it can avoid the fragments of the object splashing during the test and causing harm to the experimenter, thus improving the safety of the testing machine.

[0015] 2. The present utility model provides an upper-mounted oil cylinder pressure testing machine. The buffer plates on both sides clamp the object. When fixing the object, the impact force generated is pushed by the buffer plate to push the connecting rod and the push plate into the hollow rod, squeezing the rubber ball, which can buffer the impact force. At the same time, the air inside the hollow rod is squeezed, increasing the pressure inside the hollow rod, and then cooperating with the rubber ball to push the push plate outward, which can reduce the impact force generated during clamping, thereby avoiding damage to the test object and improving the accuracy of the test data.

[0022] The following further elaborates on the present utility model in conjunction with embodiments:

[0023] Embodiment 1

[0025] Specifically, pull up the protection plate 4, driving the limit plate 3 to move upward synchronously, so that the rubber clamping block 502 enters the positioning groove 501. The pressure on the second spring 503 decreases, then the rubber clamping block 502 is pushed into the positioning groove 501, and the air in the positioning groove 501 enters the rubber clamping block 502 through the ventilation hole 504, improving the fit between the rubber clamping block 502 and the positioning groove 501, thereby fixing the positions of the limit plate 3 and the protection plate 4. Subsequently, pull out the two flexible baffles 7 outward, stretching the first spring 6 at the same time, so that the two connecting plates 8 are in contact with each other, and then use the fixing bolt 9 to connect the two, thereby fixing the positions of the two flexible baffles 7. Cooperating with the protection plate 4, it can avoid the fragments of the object splashing during the test and causing harm to the experimental personnel, thus improving the safety of the testing machine.

[0026] Embodiment 2

[0027] As Figures 1-5 shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, a support frame 10 is fixedly connected to the base 1, a lifting assembly 11 is arranged inside the support frame 10, a first electric gripper 12 is arranged on the lifting assembly 11, and a second electric gripper 13 is arranged on the base 1;

[0028] Specifically, both ends of the object to be tested are respectively fixed in the first electric gripper 12 and the second electric gripper 13, and the lifting assembly 11 is started to drive the first electric gripper 12 to move up and down, thereby generating pressure and tension on one end of the object, and then completing the test.

[0029] Embodiment 3

[0030] As Figures 1-5 shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, a buffer plate 131 is arranged on one side of the second electric gripper 13, a hollow rod 132 is fixedly connected inside the second electric gripper 13, a rubber ball 133 is fixedly connected inside the hollow rod 132, a push plate 134 is slidably connected inside the hollow rod 132, one side of the push plate 134 is fixedly connected with a connecting rod 135, and one end of the connecting rod 135 is fixedly connected to the buffer plate 131;

[0031] Specifically, when the second electric gripper 13 fixes an object, the buffer plates 131 on both sides clamp the object. When the impact force generated during object fixation is applied, the buffer plates 131 push the connecting rod 135 and the push plate 134 into the hollow rod 132, squeezing the rubber ball 133. This can buffer the impact force and simultaneously squeeze the air inside the hollow rod 132, increasing the internal pressure of the hollow rod 132. Thus, in cooperation with the rubber ball 133, the push plate 134 is pushed outwards, reducing the impact force generated during clamping and thereby avoiding damage to the test object and improving the accuracy of test data.

[0032] Next, the working principle of the upper-mounted oil cylinder pressure testing machine will be specifically described.

[0033] As Figures 1-5 shown, both ends of the object to be tested are respectively fixed in the first electric gripper 12 and the second electric gripper 13. The buffer plates 131 on both sides clamp the object. When the impact force generated during object fixation is applied, the buffer plates 131 push the connecting rod 135 and the push plate 134 into the hollow rod 132, squeezing the rubber ball 133. This can buffer the impact force and simultaneously squeeze the air inside the hollow rod 132, increasing the internal pressure of the hollow rod 132. Thus, in cooperation with the rubber ball 133, the push plate 134 is pushed outwards, reducing the impact force generated during clamping and thereby avoiding damage to the test object. Subsequently, the protective plate 4 is pulled upwards, driving the limit plate 3 to move upwards synchronously, causing the rubber block 502 to enter the positioning groove 501. The pressure on the second spring 503 is reduced, and the rubber block 502 is pushed into the positioning groove 501, thereby fixing the positions of the limit plate 3 and the protective plate 4. Subsequently, the two flexible baffles 7 are pulled outwards, simultaneously stretching the first spring 6, causing the two connecting plates 8 to be in contact. Then, the fixing bolts 9 are used to connect the two, thereby fixing the positions of the two flexible baffles 7. In cooperation with the protective plate 4, it can prevent the fragments of the object from splashing during the test and causing harm to the experimenter. The lifting assembly 11 is started to drive the first electric gripper 12 to move up and down, thereby applying pressure and tension to one end of the object and completing the test.

[0034] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
