Description

Technical Field

[0001] This invention belongs to the technical field of hydraulic pipe strength testing, and relates to a high wear-resistant and extrusion-resistant hydraulic pipe strength testing device. Background Technology

[0002] With the continuous improvement of performance standards for hydraulic systems in the industrial sector, the wear resistance and extrusion resistance of hydraulic hoses, as a key component of hydraulic systems, have become particularly critical. These characteristics not only directly affect the overall reliability and efficiency of hydraulic systems, but also necessitate the development of more advanced materials and testing methods to ensure that hydraulic hoses maintain excellent performance under various extreme conditions. This has become an important direction in current engineering technology development.

[0003] Currently, the strength test of hydraulic hoses typically involves injecting water at a certain pressure into the hose and conducting a step-by-step pressurization test, maintaining static pressure for a period of time at each pressure stage, and observing whether the hose deforms or leaks to assess its pressure resistance. However, this method can only simply test the internal pressure-bearing capacity of the hose. In actual applications, the hose may also be affected by external pressure. Simply testing the internal pressure-bearing capacity is insufficient to simulate the impact generated by the external environment during actual use, resulting in poor test results. Summary of the Invention

[0005] The technical implementation of the present invention is as follows: a high wear-resistant and extrusion-resistant hydraulic oil pipe strength testing device, comprising a base frame, a connecting frame, a door panel, a connecting mechanism, a liquid injection mechanism, and an extrusion testing mechanism.

The connecting frame is provided with the connecting mechanism and the extrusion testing mechanism. The base frame is provided with the liquid injection mechanism, which can inject liquid into the hydraulic oil pipe. The extrusion testing mechanism is used to extrude the hydraulic oil pipe.

[0006] Furthermore, it is particularly preferred that the connecting mechanism includes an electric guide rail, a connecting plate, a fixing stud, and a pressure gauge. Electric guide rails are installed on both sides of the connecting frame, and a connecting plate is connected between the moving parts of the two electric guide rails. A pressure gauge is installed in the middle of the top of the connecting plate, and a fixing stud is connected to the bottom of the connecting plate.

[0009] Furthermore, it is particularly preferred that the device also includes a protective mechanism, which includes a protective soft cover and a connecting iron ring. The protective soft cover is connected to the bottom of the connecting plate. The protective soft cover covers the fixing stud one and fixing stud two. The connecting iron ring is provided at the bottom of the protective soft cover.

[0010] Furthermore, it is particularly preferred that a temperature control mechanism is also included, which includes an air intake frame, an air guide pipe, a connecting pipe, a fan, a cooling plate, and a heating pipe. Two air intake frames are connected to the connecting frame, and a connecting pipe is connected to each of the two air intake frames.

The air guide pipe passes through the connecting plate and communicates with the inside of the protective soft cover. A fan is installed at the air intake frame, a heating pipe is installed inside one air intake frame, and a cooling plate is installed inside the other air intake frame. Two exhaust holes are opened in the middle of the partition, and the protective soft cover can be lowered to cover the exhaust holes.

[0011] Furthermore, it is particularly preferred that the device also includes a fixing mechanism, which includes a connecting ring and an annular magnet.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0030] A high wear-resistant and compression-resistant hydraulic hose strength testing device, such as Figures 1-5 As shown, it includes a base frame 1, a connecting frame 2, a door panel 3, a connecting mechanism, a liquid injection mechanism, and a compression testing mechanism. The top of the base frame 1 is connected to the connecting frame 2, and the door panels 3 are rotatably connected to the left and right sides of the front side of the connecting frame 2. The connecting frame 2 is equipped with a connecting mechanism and a compression testing mechanism. The base frame 1 is equipped with a liquid injection mechanism, which can inject liquid into the hydraulic oil pipe 100. The compression testing mechanism is used to compress the hydraulic oil pipe 100.

[0031] like Figures 2-4 As shown, the connecting mechanism includes an electric guide rail 41, a connecting plate 42, a fixing stud 43, and a pressure gauge 44. Electric guide rails 41 are installed on both the left and right sides of the connecting frame 2. A connecting plate 42 is connected between the moving parts of the two electric guide rails 41. The electric guide rails 41 can drive the connecting plate 42 to move up and down. A pressure gauge 44 is installed in the middle of the top of the connecting plate 42. A fixing stud 43 is connected to the bottom of the connecting plate 42. The sensing end of the pressure gauge 44 passes through the fixing stud 43.

[0032] like Figures 2-4As shown, the injection mechanism includes a submerged housing 51, a partition 52, a second fixing stud 53, a water pump 54, and an injection pipe 55. The submerged housing 51 is located in the lower part of the base frame 1. The submerged housing 51 contains hydraulic oil. The top of the submerged housing 51 is connected to the partition 52. The partition 52 has multiple evenly spaced leakage holes. The second fixing stud 53 is connected to the middle of the top of the partition 52. The second fixing stud 53 is hollow inside. The water pump 54 is installed inside the submerged housing 51. The outlet end of the water pump 54 is connected to the injection pipe 55. The injection pipe 55 is connected to the inside of the second fixing stud 53.

[0033] like Figures 2-5 As shown, the extrusion testing mechanism includes an air pump 61, an air injection pipe 62, a sliding rod 63, a sliding frame 64, a screw motor 65, a cylinder 66, an extrusion column 67, an elastic element 68, and a solenoid valve 69. The air pump 61 is installed on the top right side of the connecting frame 2. The sliding rod 63 is slidably connected to the connecting plate 42. The sliding frame 64 is installed at the bottom of the sliding rod 63. The sliding rod 63 can slide up and down along the connecting plate 42. The screw motor 65 is installed on the connecting plate 42. The lead screw of the lever motor 65 is rotatably connected to the sliding frame 64, so that when the lever motor 65 operates, it can drive the sliding frame 64 to move up and down through the lead screw. Cylinders 66 are installed on both the left and right sides of the sliding frame 64. An extrusion column 67 is slidably connected inside the cylinder 66. An elastic element 68, which is a connecting spring, is connected between the extrusion column 67 and the cylinder 66. A solenoid valve 69 is provided at the bottom of the cylinder 66. The air injection pipe 62 is connected to the cylinder 66.

[0034] This device can be used to test the strength of hydraulic hose 100. During operation, both ends of hydraulic hose 100 are screwed into fixing stud 43 and fixing stud 53 respectively. After this, the water pump 54 is operated to extract hydraulic oil from the sinker 51 and send it into hydraulic hose 100 through injection pipe 55 and fixing stud 53. The pressure gauge 44 can test the internal pressure of the hose, thus achieving the effect of testing the strength of hydraulic hose 100. During pressure testing, the air pump 61 can be operated to inject gas into cylinder 66 through air injection pipe 62. The gas pushes the extrusion column 67 to move, causing the two extrusion columns 67 to move away from each other, compressing the elastic element 68. After a period of inflation, the solenoid valve 69 can be opened to release the gas. When the solenoid valve 69 releases air, it controls the air pump 61 to shut off. At this time, the gas is discharged, and under the action of the elastic element 68, the extrusion column 67 resets and can extrude the hydraulic oil pipe 100, thereby testing the extrusion strength of the hydraulic oil pipe 100. In this way, the strength test and extrusion test of the hydraulic oil pipe 100 can be achieved simultaneously. During the actual test, the screw motor 65 can be controlled to drive the screw on it to move up and down, thereby driving the sliding frame 64 to move up and down, so as to adjust the up and down position of the extrusion column 67 and adjust the position of extrusion on the hydraulic oil pipe 100, so as to test the strength at different positions on the hydraulic oil pipe 100. At the same time, the electric guide rail 41 can be controlled to drive the connecting plate 42 to rise and fall according to the different lengths of the hydraulic oil pipe 100, thereby adjusting the distance between the first fixing stud 43 and the second fixing stud 53.

[0035] like Figure 6 and Figure 7 As shown, it also includes a protective mechanism, which includes a protective soft cover 71 and a connecting iron ring 72. The bottom of the connecting plate 42 is connected to the protective soft cover 71. The protective soft cover 71 covers the fixing stud 43 and the fixing stud 53. The bottom of the protective soft cover 71 is provided with a connecting iron ring 72.

[0036] When testing the hydraulic oil pipe 100, the protective soft cover 71 can be pulled down by the connecting iron ring 72, so that the protective soft cover 71 covers the hydraulic oil pipe 100 during the test. If the hydraulic oil pipe 100 breaks during the test, the protective soft cover 71 can block the hydraulic oil in the hydraulic oil pipe 100, thus preventing the hydraulic oil from splashing during the test.

[0037] like Figures 8-10As shown, it also includes a temperature control mechanism, which includes an air intake frame 81, an air guide pipe 82, a connecting pipe 87, a fan 83, a cooling element 85, and a heating element 86. Two air intake frames 81 are connected to the upper rear side of the connecting frame 2, and a connecting pipe 87 is connected to each of the two air intake frames 81. A one-way valve is provided at the connecting pipe 87. An air guide pipe 82 is connected between the two connecting pipes 87. The air guide pipe 82 passes through the connecting plate 42 and communicates with the inside of the protective soft cover 71. A fan 83 is installed at the air intake frame 81. A heating element 86 is installed inside the left air intake frame 81, and a cooling element 85 is installed inside the right air intake frame 81. Two exhaust holes are opened in the middle of the partition plate 52. The protective soft cover 71 can be lowered to cover the exhaust holes. When gas is added into the protective soft cover 71, the excess gas will be discharged through the exhaust holes.

[0038] During the test, the operation of the cooling element 85 can be controlled, and then the operation of the fan 83 near the cooling element 85 can be controlled to inject cold air into the protective soft cover 71 through the air guide pipe 82 and the connecting pipe 87, so that the hydraulic oil pipe 100 cools down and is tested in a low-temperature environment. The operation of the heating element 86 can also be controlled, and then the operation of the fan 83 near the heating element 86 can be controlled to inject hot air into the protective soft cover 71 through the air guide pipe 82 and the connecting pipe 87, so that the hydraulic oil pipe 100 heats up and is tested in a high-temperature environment. In this way, by using the cooling element 85 and the heating element 86 together, the effect of simulating high-temperature and low-temperature environment testing can be achieved, so as to simulate the strength of the hydraulic oil pipe 100 under different environments.

[0039] like Figure 11 As shown, it also includes a fixing mechanism, which includes a connecting ring 91 and an annular magnet 92. The connecting ring 91 is connected to the middle of the bottom of the connecting plate 42, and the annular magnet 92 is connected to the bottom of the connecting ring 91.

[0040] like Figure 12 and Figure 13 As shown, it also includes a second annular magnet 10. Two second annular magnets 10 are connected to the top of the partition 52. The second annular magnets 10 can attract the connecting iron ring 72.

[0041] After the test is completed, pull the connecting iron ring 72 upward to retract the protective soft cover 71. The upward movement of the connecting iron ring 72 allows it to contact the annular magnet 92, which in turn attracts the connecting iron ring 72. During the test, the connecting iron ring 72 can be pulled downward to magnetically attract the annular magnet 10, thus helping to fix the connecting iron ring 72.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
