The mechanical device has relatively simple structure and low cost, but it cannot provide fast cycle test under constant load, and the process of adjusting load is tedious, and the load response time is long. In addition, when the slip force test of the actuator is needed, this structure is difficult to realize the required dynamic response. The pneumatic adjustable load device has the advantage of convenient load adjustment, but its load dynamic response time is relatively long, which limits its application in high precision and fast response occasions. Although the hydraulic load test bench can provide a larger load range, its structure is complex, and the dynamic response speed is not ideal. In addition, the hydraulic system often accompanies high energy consumption and maintenance cost. The electromagnetic load adjustment method is not only convenient and fast, but also has a faster dynamic response speed. However, such equipment is bulky, has high energy consumption, and has high initial investment and operation cost.

DETAILED DESCRIPTION
[0022] The utility model is further illustrated by examples below, which aims to more clearly illustrate the technical scheme of the utility model, and should not be understood as a kind of limitation.
[0023] A portable variable load thrust test device is provided, which can be used for load test of thrust actuator.
[0024] As Figures 1 to 4As shown, the testing device comprises a support 1, which is the basic structure of the whole testing device, and mainly comprises a bottom plate and a column connected integrally. The support 1 has a longitudinal sliding groove 11 and a transverse sliding groove 12; the longitudinal sliding groove 11 is slidably fitted with a longitudinal sliding block 2, and the transverse sliding groove 12 is slidably fitted with a transverse sliding block 3; the longitudinal sliding block 2 is provided with a first guide surface 21 on the side facing the transverse sliding block 3, and the first guide surface 21 forms a 45° angle with the sliding direction of the longitudinal sliding block 2; the transverse sliding block 3 is provided with a second guide surface 31 on the side facing the longitudinal sliding block 2, and the second guide surface 31 forms a 45° angle with the sliding direction of the transverse sliding block 3; the first guide surface 21 and the second guide surface 31 are slidably abutted, so as to ensure that the first guide surface 21 can keep in contact with the second guide surface 31 when the longitudinal sliding block 2 moves up and down, and the longitudinal force can be converted into a transverse force of equal size. The longitudinal sliding block 2 is provided with a hanging device 29 for hanging a weight block 9 of adjustable weight, so as to adjust the size of the load according to the experimental requirements, and simulate different load conditions that the thrust actuator may encounter during work. The support 1 is provided with a loading table 13 in the extension direction of the transverse sliding groove 12, and the loading table 13 is used for fixing the thrust actuator to be detected.
[0025] During testing, the testing device is stably placed on a flat and stable surface; the thrust actuator is fixed on the loading table 13, and the front end of the push rod faces the transverse sliding block 3; the thrust actuator is started to generate thrust, and with the application of the thrust, the transverse sliding block 3 is pushed to move along the transverse sliding groove 12, so as to press the longitudinal sliding block 2; the contact between the first guide surface 21 of 45° and the second guide surface 31 of 45° converts the transverse force into a longitudinal force of equal size, so that the longitudinal sliding block 2 moves upward along the longitudinal sliding groove 11. The durability of the actuator is evaluated by keeping the longitudinal sliding block 2 at a certain height or pushing the longitudinal sliding block 2 to a specified position for multiple times.
[0026] In some preferred embodiments, the part where the first guide surface 21 and the second guide surface 31 are in contact is coated with a lubricating medium. The lubricating medium can significantly reduce the friction coefficient between the two contact surfaces, help reduce energy loss when the sliding block moves, and enable the sliding block to slide more smoothly, thereby improving the efficiency and accuracy of the whole testing process.
[0027] In some preferred embodiments, rolling slide rails are adopted between the longitudinal sliding groove 11 and the longitudinal sliding block 2, and between the transverse sliding groove 12 and the transverse sliding block 3, so as to reduce friction and improve the accuracy of testing.
[0028] As Figure 1 and Figure 2As shown in some preferred embodiments, the suspension device 29 is a suspension cable fixed to the bottom of the longitudinal slider 2; the bottom of the bracket 1 has a through hole for the suspension device 29 to pass through, which allows the user to conveniently suspend and adjust and replace the weight blocks 9 of different weights to adapt to different test requirements. In addition, this structure also facilitates maintenance and inspection, and the suspension cable is easy to disassemble and install, making the assembly and disassembly process of the entire system more convenient.
[0029] In some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11.
[0030] As shown in some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11. Figure 2 and Figure 3 As shown in some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11.
[0031] As shown in some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11. Figure 2 and Figure 3 As shown in some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11.
[0032] As shown in some preferred embodiments, the top end of the longitudinal sliding groove 11 is provided with a limiting device to limit the upper sliding limit position of the longitudinal slider 2, so as to avoid accidental outflow of the longitudinal slider 2 from the longitudinal sliding groove 11. Figure 4 As shown in some preferred embodiments, the tail end of the limiting slider 4 is cylindrical and partially exposed outside the lateral wall of the longitudinal sliding groove 11; the tail end of the limiting slider 4 has a scale. The scale value of the tail end of the limiting slider 4 corresponds to the thrust value of the limiting slider 4 exerted by the elastic element 5 after being compressed. This structure allows the operator to intuitively observe the movement of the limiting slider 4 during the test process, facilitating real-time monitoring; through the scale value, the thrust value of the limiting slider 4 exerted by the elastic element 5 after being compressed can be directly read, so as to accurately evaluate the slip force characteristics of the thrust executor and simplify the measurement process.
[0033] The above embodiments are exemplary, and the purpose is to illustrate the technical concept and characteristics of the utility model, so that those skilled in the art can understand the content of the utility model and implement it, and the protection scope of the utility model cannot be limited thereby. Any equivalent change or modification according to the spirit and essence of the utility model should be covered within the protection scope of the utility model.
