[0019] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] The following is for reference. Figures 1-4 Describes the test equipment according to embodiments of this application.

[0021] Please see Figure 1 and Figure 2 This application provides a test device 1, which is used as a work platform 2 for loading and unloading equipment.

[0022] Loading and unloading equipment typically refers to engineering machinery or industrial equipment used for loading, unloading, transferring, and stacking of goods, such as forklifts, loading arms, stackers, logistics loading and unloading platforms, and port lifting and unloading devices. This type of equipment is mainly used in warehousing, logistics, ports, workshops, and other places, undertaking core operational tasks such as handling, loading, unloading, lifting, and transferring of goods, and is an important piece of equipment for achieving efficient material flow.

[0023] As the core working component of the loading and unloading equipment that directly bears, contacts, or acts on the goods, the working platform 2 is mainly used to support the goods and perform lifting, extending, flipping, and lateral movements in coordination with loading and unloading actions. Some working platforms 2 can also adjust their posture according to the shape of the goods or operational needs to adapt to the loading and unloading requirements of goods of different sizes and weights. The structural strength, motion accuracy, load-bearing capacity, motion stability, and connection reliability of the working platform 2 directly determine the overall operational performance and safety of the loading and unloading equipment. Therefore, before the development, production, and delivery of the loading and unloading equipment, it is necessary to conduct special tests and functional performance tests on the working platform 2 to ensure that it can meet the actual loading and unloading operation requirements.

[0024] The test equipment 1 includes multiple movable supports 10 and multiple sets of connecting components 20. The multiple movable supports 10 are arranged sequentially in the horizontal direction and spaced apart from each other, and the multiple movable supports 10 are movably set in the horizontal direction; the multiple sets of connecting components 20 are installed one-to-one with the multiple movable supports 10, and the connecting components 20 are movably set relative to the movable supports 10. The connecting components 20 are used to connect to the work platform 2, and the connecting components 20 can drive the work platform 2 to move.

[0025] Multiple movable supports 10 form the main support structure of the test equipment 1. These supports are arranged sequentially in the transverse direction, with a preset interval between adjacent supports. This interval can be adjusted according to actual test requirements. The multiple movable supports 10 are movably positioned in the transverse direction. The transverse movement of the supports 10 can be achieved through various methods such as slide rail sliding, screw drive, and rack and pinion drive. In the slide rail sliding method, a transversely extending guide rail 30 is provided at the bottom of the movable support 10, allowing it to slide linearly along the guide rail 30. In the screw drive method, the movable support 10 is threadedly engaged with a transversely positioned screw, and rotating the screw drives the movable support 10 to move laterally.

[0026] The number of movable supports 10 is not specifically limited and is determined according to the support requirements of the work platform 2. There can be two, three, four or more. When there are two movable supports 10, the two movable supports 10 are symmetrically arranged on both sides of the test equipment 1. When there are three or more movable supports 10, each movable support 10 is evenly spaced along the transverse direction to form a multi-point support and connection foundation for the work platform 2.

[0027] Multiple sets of connecting components 20 are set one-to-one with multiple movable supports 10. Each set of connecting components 20 is installed on a corresponding movable support 10. The connecting component 20 serves as an intermediate connecting part between the work platform 2 and the movable support 10, and also as an execution part that drives the work platform 2 to move.

[0028] The connecting component 20 is movably set relative to the movable support 10. Its movement direction can be vertical, longitudinal, or multi-angle swing. The movement form can be implemented by means of hinge sliding, telescopic adjustment, and rotating shaft. In the hinge sliding mode, the connecting component 20 and the movable support 10 achieve sliding adjustment through the hinge seat and the sliding groove. In the telescopic adjustment mode, the connecting component 20 adopts a multi-stage telescopic rod 22 structure, which can move telescopically relative to the movable support 10.

[0029] The end of the connecting component 20 is used for detachable connection with the working platform 2 of the loading and unloading equipment. The connection can be made by bolt fastening, snap-fit, flange connection, etc., to ensure the connection stability between the working platform 2 and the connecting component 20, and at the same time facilitate the disassembly and replacement of different working platforms 2.

[0030] The connecting component 20 has its own driving function, which can drive the connected work platform 2 to move, swing, extend and retract under the action of power. Its driving source can be electric push rod, hydraulic cylinder, pneumatic cylinder or rotary motor and other driving components. The driving components are integrated inside or outside the connecting component 20 to provide power for the movement of the work platform 2.

[0031] During the test, the positions of multiple movable supports 10 were first adjusted laterally according to the lateral dimensions of the work platform 2 under test, changing the spacing between adjacent movable supports 10 to match the arrangement dimensions of the movable supports 10 with the dimensions of the connection parts of the work platform 2. Then, the positions of the connecting components 20 on each movable support 10 were adjusted to ensure precise alignment of the connecting components 20 with the connection points of the work platform 2 and to complete the fixed connection. After the work platform 2 was installed and fixed, the drive structure of the connecting components 20 was activated. The connecting components 20 then drove the work platform 2 to move along a preset trajectory, simulating the lifting, swinging, and translating conditions of the work platform 2 during actual operation of the loading and unloading equipment. This allowed for testing of the load-bearing capacity, operational stability, and structural strength of the work platform 2.

[0032] According to the test equipment 1 provided in the embodiments of this application, by setting multiple movable supports 10 that are movable in the lateral direction and multiple sets of connecting components 20 that are movable relative to the movable supports 10, it can flexibly adjust and adapt to loading and unloading equipment operating platforms 2 of different sizes and specifications. This eliminates the need to manufacture dedicated test equipment 1 for different operating platforms 2, effectively reducing the manufacturing cost and resource waste of the test equipment 1. Simultaneously, the connecting components 20 can directly drive the operation of the operating platform 2, realistically simulating actual working conditions, ensuring the accuracy of test results. Performance verification is not required after the operating platform 2 is produced, avoiding rework and optimization due to substandard performance, accelerating the development progress of loading and unloading equipment products, and improving overall production efficiency.

[0033] According to the test equipment 1 of this application, by adjusting the spacing of the movable support 10 and the position of the connecting component 20, the connection size of different work platforms 2 can be adapted, and by driving the work platform 2 to move through the connecting component 20, the working state under different working conditions can be simulated.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4According to some embodiments of this application, the connecting component 20 may include a mounting base 21 and a telescopic rod 22. The mounting base 21 is vertically movably mounted on the movable bracket 10 and is provided with a first connecting part 212. One end of the telescopic rod 22 is rotatably connected to the movable bracket 10 and is rotatable about an axis extending laterally. The other end of the telescopic rod 22 is provided with a second connecting part 221. The first connecting part 212 and the second connecting part 221 are respectively used to rotatably connect with two mating parts on the working platform 2.

[0035] The mounting base 21 is vertically movably mounted on the movable bracket 10. The vertical movement can be achieved by using a sliding groove and slider, a vertical screw drive, or a cylinder or hydraulic cylinder to drive the lifting. In the sliding groove and slider configuration, the movable bracket 10 has a guide groove extending vertically on the side facing the work platform 2. A sliding block that matches the sliding groove is fixed on the mounting base 21. The sliding block is embedded in the sliding groove, allowing the mounting base 21 to slide up and down along the sliding groove to adjust its height. In the vertical screw drive configuration, the mounting base 21 is threadedly engaged with a vertically arranged screw. By rotating the screw, the mounting base 21 can be stably raised and lowered. After adjustment, it can be positioned by a locking device.

[0036] The first connecting part 212 provided on the mounting base 21 is used to connect with one of the mating parts on the working platform 2. The first connecting part 212 can adopt the structure of hinged ear plate 2121, pin hole, ball joint, etc., which can realize rotational mating with the working platform 2 and adapt to the posture changes of the working platform 2.

[0037] One end of the telescopic rod 22 is rotatably connected to the movable bracket 10. The axis of this rotatable connection extends laterally, allowing the telescopic rod 22 to swing up and down around the lateral axis in a vertical plane. The rotatable connection structure can be in the form of pin hinge, rotating shaft with bearing, etc., to ensure that the telescopic rod 22 rotates smoothly and bears reliable load.

[0038] The telescopic rod 22 has its own length extension and retraction adjustment function. It can be an electric telescopic rod 22, a hydraulic telescopic rod 22, a pneumatic telescopic rod 22, or a multi-stage manual telescopic rod, etc. By changing its length and swinging itself, it can drive the work platform 2 in different postures. The end of the telescopic rod 22 away from the movable support 10 is provided with a second connecting part 221. The second connecting part 221 can also adopt a hinged ear plate 2121, a pin hole, a ball joint, etc., for rotational connection with another mating part on the work platform 2.

[0039] The first connecting part 212 and the second connecting part 221 respectively connect to two different mating parts on the work platform 2. The two mating parts can be pre-set structures such as hinge seats and connecting lugs on the body of the work platform 2. Through the mating of the two rotating connections, the mounting base 21 and the telescopic rod 22 together form a stable two-point support constraint for the work platform 2. It can be understood that the work platform 2 is provided with multiple sets of assembly parts, and each set of assembly parts is provided with a movable bracket 10 and a set of connecting components 20.

[0040] During the experiment, the vertical position of the mounting base 21 on the movable bracket 10 can be adjusted according to the vertical height of the two mating parts on the working platform 2, so that the first connecting part 212 is aligned and connected with the corresponding mating part. Then, by adjusting the rotation and extension of the telescopic rod 22, the second connecting part 221 is precisely connected with the other mating part, completing the assembly of the working platform 2 and the connecting component 20. After assembly, the extension and retraction of the telescopic rod 22 and its swinging motion around the horizontal axis, combined with the vertical fine adjustment of the mounting base 21, can jointly drive the working platform 2 to complete various actions such as lifting, tilting, and tilting, realistically simulating the working posture of the loading and unloading equipment working platform 2 when actually loading and unloading goods.

[0041] Please see Figure 1 , Figure 3 and Figure 4 The movable support 10 may include a first longitudinal beam 11, a first vertical beam 14, a second vertical beam 15, and a second longitudinal beam 12. The first longitudinal beam 11 extends longitudinally; the first vertical beam 14 extends vertically, and its lower end is connected to the first longitudinal beam 11; the second vertical beam 15 extends vertically, and its lower end is connected to the first longitudinal beam 11 and spaced longitudinally from the first vertical beam 14, with the height of the second vertical beam 15 being less than the height of the first vertical beam 14; the second longitudinal beam 12 extends longitudinally and connects between the first vertical beam 14 and the second vertical beam 15, with one end of the second longitudinal beam 12 connected to the upper end of the second vertical beam 15 and the other end connected to the first vertical beam 14 and spaced apart from the upper end of the first vertical beam 14; wherein, the mounting base 21 is vertically movably mounted on the side of the second vertical beam 15 away from the first vertical beam 14, and one end of the telescopic rod 22 is rotatably connected to the upper end of the first vertical beam 14.

[0042] The first longitudinal beam 11, the first vertical beam 14, the second vertical beam 15, and the second longitudinal beam 12 are interconnected to form a stable frame structure, which can provide a reliable installation foundation for the connecting component 20 and adapt to the installation position requirements of the mounting base 21 and the telescopic rod 22, ensuring the stability of the connecting component 20 when it operates.

[0043] The first longitudinal beam 11 extends longitudinally and serves as the bottom support component of the movable bracket 10, bearing the weight of the entire movable bracket 10 and the components installed on it. It also provides connection support points for the first vertical beam 14 and the second vertical beam 15. The structure of the first longitudinal beam 11 can be made of rectangular tubing, I-beams, channel steel, etc., and its length is not specifically limited. It can be flexibly set according to the overall size requirements of the movable bracket 10. The longitudinal extension direction is perpendicular to the lateral movement direction of the movable bracket 10, ensuring that the first longitudinal beam 11 can stably support the movable bracket 10 when it moves laterally.

[0044] The first vertical beam 14 extends vertically, and its lower end is fixedly connected to the first longitudinal beam 11. The connection method can be welding, bolting, or integral molding. Welding ensures connection strength, while bolting facilitates disassembly and maintenance. As the main vertical support component of the movable bracket 10, the first vertical beam 14 is higher than the second vertical beam 15. Its upper end is used to install the telescopic rod 22, providing a stable support point for the rotation of the telescopic rod 22. The structure of the first vertical beam 14 can be the same as that of the first longitudinal beam 11, using rectangular square tubes, I-beams, etc., to ensure sufficient structural strength to withstand the force generated when the telescopic rod 22 moves.

[0045] The second vertical beam 15 also extends vertically, with its lower end fixedly connected to the first longitudinal beam 11. It is longitudinally spaced from the first vertical beam 14, and this spacing can be flexibly adjusted according to the installation requirements of the connecting assembly 20, ensuring that the installation positions of the mounting base 21 and the telescopic rod 22 do not interfere with each other, while also adapting to the connection point layout of the work platform 2. The height of the second vertical beam 15 is less than that of the first vertical beam 14. Its upper end is connected to the second longitudinal beam 12, forming the upper auxiliary support structure of the movable bracket 10. The side facing away from the first vertical beam 14 is used to install the mounting base 21, providing guidance and support for the vertical movement of the mounting base 21. The structure of the second vertical beam 15 is adapted to that of the first vertical beam 14, ensuring the consistency and stability of the overall structure.

[0046] The second longitudinal beam 12 extends longitudinally and connects the first vertical beam 14 and the second vertical beam 15. One end of the second longitudinal beam 12 is fixedly connected to the upper end of the second vertical beam 15, and the other end is connected to the first vertical beam 14 and spaced apart from the upper end of the first vertical beam 14. The second longitudinal beam 12 enhances the connection stability between the first vertical beam 14 and the second vertical beam 15, preventing deformation due to longitudinal spacing. It also helps to share the force borne by the first vertical beam 14 and the second vertical beam 15, improving the structural rigidity of the entire movable support 10. The structure of the second longitudinal beam 12 is the same as that of the first longitudinal beam 11, and the connection can be made by welding or bolting to ensure reliable connection.

[0047] The mounting base 21 is vertically movably mounted on the side of the second vertical beam 15 opposite to the first vertical beam 14. This mounting position allows the first connecting part 212 of the mounting base 21 to be closer to the mating part of the work platform 2, facilitating the connection between the two and avoiding interference with the first vertical beam 14 and the telescopic rod 22. A vertically extending guide structure, such as a guide groove or a vertical guide rail 30, can be provided on the side of the second vertical beam 15 opposite to the first vertical beam 14. This guide structure cooperates with the sliding parts on the mounting base 21 to achieve smooth vertical movement of the mounting base 21.

[0048] One end of the telescopic rod 22 is rotatably connected to the upper end of the first vertical beam 14. Since the first vertical beam 14 is higher than the second vertical beam 15, the pivot point of the telescopic rod 22 is higher than the installation height of the mounting base 21. This height difference, combined with the extension and rotation of the telescopic rod 22, allows for more flexible driving of the work platform 2 to complete pitch, tilt, and other attitude adjustments. Simultaneously, it ensures that the telescopic rod 22 and the mounting base 21 do not interfere with each other during operation, improving the overall coordination of the connecting assembly 20. Furthermore, because the first vertical beam 14 and the second vertical beam 15 are spaced apart, the other end of the telescopic rod 22 must extend at least to the second vertical beam 15, extending the overall length of the telescopic rod 22 and thus increasing its range of motion. Additionally, the telescopic rod 22 and the mounting base 21 are installed on different vertical beams, making the overall force distribution on the movable support 10 more even and its stability higher. The rotatable connection between the telescopic rod 22 and the upper end of the first vertical beam 14 can be achieved using a pin hinge, a rotating shaft with bearings, or other methods, with the rotation axis extending laterally.

[0049] In some examples, the two mating parts on the work platform 2 are vertically aligned, and the telescopic rod 22 is located above the mounting base 21. In its initial state, the telescopic rod 22 can extend horizontally, so that the second connecting part 221 on the telescopic rod 22 is vertically aligned with the first connecting part 212. The height of the mounting base 21 is adjusted according to the distance between the two assembly parts so that the distance between the first connecting part 212 and the second connecting part 221 corresponds to the distance between the two mating parts. Then, the first connecting part 212 and the second connecting part 221 are respectively connected to the two mating parts. When the telescopic rod 22 is shortened, the work platform 2 is in an upward tilting state, and when the telescopic rod 22 is extended, the work platform 2 is in a downward tilting state.

[0050] Please see Figure 1 , Figure 3 and Figure 4According to some embodiments of this application, the movable support 10 of the test equipment 1 may further include a support base 17. The support base 17 may include two stiffening plates 171. The two stiffening plates 171 extend longitudinally and are spaced laterally. One end of the stiffening plate 171 in the longitudinal direction is connected to the side of the first vertical beam 14 facing the second vertical beam 15. The lower end of the stiffening plate 171 is connected to the upper side wall of the second vertical beam 12. One end of the telescopic rod 22 is rotatably connected between the two stiffening plates 171 and is connected to the upper end of the stiffening plate 171 near the first vertical beam 14.

[0051] The support base 17 is mainly used to provide a stable and reliable rotating installation base for the telescopic rod 22, so as to avoid the problem of stress concentration and insufficient connection strength caused by the telescopic rod 22 being directly hinged to the upper end of the first vertical beam 14, and at the same time ensure that the telescopic rod 22 will not wobble or shake during rotation.

[0052] The support base 17 is composed of two stiffening plates 171, both of which extend longitudinally and are spaced apart from each other in the transverse direction, forming an installation space between them to accommodate the end of the telescopic rod 22.

[0053] One end of the stiffening plate 171 in the longitudinal direction is connected to the side of the first vertical beam 14 facing the second vertical beam 15. The connection method can be welding, bolting, or integral molding. Welding can ensure the connection rigidity between the stiffening plate 171 and the first vertical beam 14, while bolting facilitates later disassembly and maintenance. The lower end of the stiffening plate 171 is connected to the upper side wall of the second longitudinal beam 12, so that the stiffening plate 171 receives dual support from the first vertical beam 14 and the second longitudinal beam 12, forming a triangular stable support structure, which significantly improves the overall support rigidity, effectively disperses the load transmitted to the upper end of the first vertical beam 14 when the telescopic rod 22 moves, and prevents the upper end of the first vertical beam 14 from deforming or being damaged due to repeated stress.

[0054] One end of the telescopic rod 22 is rotatably connected between two stiffening plates 171, and its installation position is located at the upper end of the stiffening plate 171 near the first vertical beam 14. This arrangement makes the rotation center of the telescopic rod 22 more stable, and at the same time makes the swing trajectory of the telescopic rod 22 more matched with the connection point of the working platform 2. Hinge holes can be opened on the inner sidewalls of the two stiffening plates 171 respectively. The end of the telescopic rod 22 is hinged between the two hinge holes by a structure such as a pin, bearing or bushing, so that the telescopic rod 22 can rotate smoothly around the horizontally extending axis. During the rotation, the two stiffening plates 171 provide lateral restraint to prevent the telescopic rod 22 from lateral movement and ensure the motion accuracy when driving the working platform 2.

[0055] During the operation of the test equipment 1, the tensile and compressive forces and overturning forces generated by the extension, contraction, and swing of the telescopic rod 22 are transmitted to the stiffening plate 171 through the hinge point, and then distributed by the stiffening plate 171 to the first vertical beam 14 and the second longitudinal beam 12, and finally transmitted to the overall structure of the movable support 10, thus avoiding excessive local stress. The setting of the support seat 17 not only improves the structural strength and service life of the hinge part of the telescopic rod 22, but also ensures the coaxiality and stability of the movement of the telescopic rod 22, making the working platform 2 more stable and reliable when simulating various working conditions, further improving the accuracy of test data, and also enhancing the overall structural rigidity of the upper part of the movable support 10, extending the service life of the test equipment 1.

[0056] Please see Figure 1 , Figure 3 and Figure 4 According to some embodiments of this application, the cross-sectional shape of the stiffening plate 171 in the transverse direction is L-shaped. The stiffening plate 171 includes a first extension extending vertically and a second extension extending longitudinally. The second extension is connected to the lower end of the first extension. The first extension is fixedly connected to the first vertical beam 14, and the second extension is connected to the upper side wall of the second longitudinal beam 12. One end of the telescopic rod 22 is connected to the upper end of the first extension.

[0057] The stiffener 171 has an L-shaped cross-section in the transverse direction. It is composed of two parts: a first extension and a second extension. The first extension extends vertically, and the second extension extends longitudinally. The second extension is directly connected to the lower end of the first extension. The two are perpendicular to each other to form a stable L-shaped support structure. This structure can withstand both vertical loads and longitudinal bending moments at the same time and is not prone to bending or twisting.

[0058] One end of the telescopic rod 22 is rotatably connected to the upper end of the first extension, which is located above the first vertical beam 14 and close to the inner side of the support base 17. This allows the rotation fulcrum of the telescopic rod 22 to be more concentrated, and the swing trajectory to better meet the movement requirements of the working platform 2. Furthermore, the upper end of the first extension extends above the second extension, and the L-shaped structure forms a notch. After the telescopic rod 22 is connected to the upper end of the first extension, the notch position allows the telescopic rod 22 to rotate, reducing the risk of interference during operation.

[0059] The upper end of the first extension can be provided with a hinge hole or hinge lug for inserting a pin and hinged to the end of the telescopic rod 22. The hinge axis extends laterally, allowing the telescopic rod 22 to swing smoothly in the vertical plane. At the same time, the L-shaped stiffener 171 structure can provide sufficient support thickness for the hinge part, preventing the hinge hole from deforming due to excessive force, and ensuring that the telescopic rod 22 rotates smoothly without jamming.

[0060] Please see Figure 1 , Figure 3 and Figure 4According to some embodiments of this application, the movable bracket 10 may further include a third vertical beam 16 and a third longitudinal beam 13. The third vertical beam 16 extends vertically, and its lower end is connected to the first longitudinal beam 11. The first brush collar and the third vertical beam 16 are respectively connected to the two ends of the first longitudinal beam 11. The second vertical beam 15 is connected to the middle of the first longitudinal beam 11, and the height of the third vertical beam 16 is less than the height of the second vertical beam 15. The third longitudinal beam 13 extends longitudinally and is connected between the second vertical beam 15 and the third vertical beam 16. One end of the third longitudinal beam 13 is connected to the upper end of the third vertical beam 16, and the other end of the third longitudinal beam 13 is connected to the second vertical beam 15 and spaced apart from the upper end of the second vertical beam 15. The mounting base 21 is movable between the upper end of the second vertical beam 15 and the third longitudinal beam 13.

[0061] The third vertical beam 16 extends vertically and is fixedly connected to the first longitudinal beam 11 at its lower end. The first vertical beam 14 and the third vertical beam 16 are located at opposite ends of the length of the first longitudinal beam 11, while the second vertical beam 15 is located in the middle of the first longitudinal beam 11. The three beams are arranged sequentially along the longitudinal direction, forming a continuous support structure for the movable support 10 in the longitudinal direction. This avoids the problem of excessively large suspended area and uneven stress on the working platform 2 due to insufficient longitudinal support span. The height of the third vertical beam 16 is less than the height of the second vertical beam 15, so that the upper end of the third vertical beam 16 is lower than the upper end of the second vertical beam 15, thus creating a height difference between the second vertical beam 15 and the third vertical beam 16. This provides space for the subsequent arrangement of the third longitudinal beam 13 and the vertical movement of the mounting base 21.

[0062] The third longitudinal beam 13 extends longitudinally and is positioned between the second vertical beam 15 and the third vertical beam 16. One end of the third longitudinal beam 13 is fixedly connected to the upper end of the third vertical beam 16, and the other end extends toward the second vertical beam 15, maintaining a distance from the upper end of the second vertical beam 15. This structure reliably connects the second vertical beam 15 and the third vertical beam 16, improving the overall rigidity of the lower structure of the movable support 10, without interfering with the vertical movement path of the mounting base 21. The connection between the third longitudinal beam 13 and the second vertical beam 15 and the third vertical beam 16 can be achieved by welding or bolting, ensuring that the overall frame is not easily deformed and can stably withstand the loads transmitted by the working platform 2 and the connecting assembly 20.

[0063] Since the entire working platform 2 is located above the longitudinal extension area after the connection is completed, the addition of the third vertical beam 16 and the third longitudinal beam 13 significantly increases the bottom support span of the movable support 10, greatly improving the bending resistance and overturning resistance of the overall frame. When the telescopic rod 22 drives the working platform 2 to perform pitching, swinging and other actions, it can effectively prevent the movable support 10 from shaking, deforming or tilting, ensuring the continuous stability of the test process and the authenticity and reliability of the test data.

[0064] Please see Figure 1 , Figure 3and Figure 4 According to some embodiments of this application, the first connecting part 212 is provided with a first connecting hole that extends laterally, and the first connecting part 212 is used to rotatably connect with the mating part through a connecting pin 3 that passes through the mating part and the first connecting hole.

[0065] The first connecting part 212 is provided with a first connecting hole that runs horizontally through the center. The first connecting hole is either a smooth hole or a threaded hole with smooth walls and high coaxiality to ensure smooth rotation without jamming. The corresponding mating part on the working platform 2 is also provided with a through hole that matches the first connecting hole. During assembly, the connecting pin 3 is sequentially inserted into the through hole of the mating part and the first connecting hole, so that the first connecting part 212 and the mating part form a hinge structure. The two can rotate relative to each other around the axis of the connecting pin 3. The connecting pin 3 can be a pin, bolt, hinge shaft, or other structures. A bushing or bearing can also be fitted on the outside of the connecting pin 3 to further reduce rotational friction and extend service life.

[0066] According to some embodiments of this application, the second connecting part 221 is provided with a second connecting hole that extends laterally, and the second connecting part 221 is used to rotatably connect with the mating part through a connecting pin 3 that passes through the mating part and the second connecting hole.

[0067] The second connecting part 221 is provided with a second connecting hole that runs horizontally through it. The second connecting hole is similar in arrangement to the first connecting hole, also running horizontally through it, and is used to achieve a rotatable connection with another mating part on the work platform 2 via a connecting pin 3. The connecting pin 3 also passes through the through hole of the second connecting hole and the corresponding mating part, so that the second connecting part 221 and the mating part form a hinged structure that can rotate relative to each other. This ensures that the work platform 2 can freely adjust its posture during the extension, retraction and swinging of the telescopic rod 22, without jamming or being subjected to forced force.

[0068] During the use of test equipment 1, connecting pin 3 ensures a reliable connection between the working platform 2 and the connecting component 20, withstands tensile and compressive loads and overturning moments during the test, and meets the rotation requirements of the working platform 2 under simulated working conditions, making the movement more closely resemble the actual loading and unloading operation. At the same time, the connecting pin 3 is easy to assemble and disassemble, allowing for quick replacement and debugging of different working platforms 2, further improving the efficiency of test equipment 1 and reducing test preparation time.

[0069] Please see Figure 1 , Figure 3 and Figure 4 According to some embodiments of this application, the mounting base 21 may include a base body 211, which is movably connected to the movable bracket 10. The first connecting part 212 includes two ear plates 2121 that extend longitudinally and are spaced apart laterally. The two ear plates 2121 are located on the side of the base body 211 away from the movable bracket 10, and the first connecting hole passes through the two ear plates 2121 in sequence.

[0070] The seat 211 is directly and movably connected to the movable bracket 10. The mating structure between the two can be in the form of a slider and a vertical guide rail 30, or a sliding sleeve and a guide post, so that the seat 211 can slide stably along the vertical of the movable bracket 10. After adjustment, it can be positioned by a set screw, a locking pin or a buckle to ensure that no accidental slippage occurs during the test.

[0071] The first connecting part 212 consists of two ear plates 2121, both extending longitudinally and spaced apart laterally, forming a clamping space to accommodate the corresponding mating parts of the work platform 2. The number of ear plates 2121 is not specifically limited and can be two, three, or more. When two ear plates 2121 are used, they are symmetrically distributed on both sides of the seat 211 away from the movable bracket 10, providing stable clamping for the mating parts of the work platform 2 and effectively preventing lateral swaying or shaking after connection. Both ear plates 2121 are fixedly connected to the seat 211. The connection method can be welding, bolting, or integral molding, ensuring the connection strength between the ear plates 2121 and the seat 211, and capable of withstanding the tensile and torsional forces generated during the movement of the work platform 2.

[0072] The first connecting hole passes through the two ear plates 2121 sequentially along the transverse direction. The first connecting holes on the two ear plates 2121 are coaxially arranged and have the same diameter, which facilitates the smooth insertion of the connecting pin 3 and enables rotational engagement. The connecting pin 3 passes through the first connecting holes on the two ear plates 2121 and the corresponding holes on the mating part of the working platform 2, allowing the working platform 2 to rotate freely around the transverse axis between the two ear plates 2121. The structure of the double ear plate can effectively increase the bearing area of ​​the hinge part, disperse local stress, and prevent the single ear plate 2121 from being deformed or broken due to excessive force.

[0073] According to some embodiments of this application, the telescopic rod 22 may include a first rod segment, a second rod segment, and a threaded sleeve. One end of the first rod segment is rotatably connected to the movable bracket 10, and the other end is provided with an external thread; one end of the second rod segment is rotatably connected to a mating part, and the other end is provided with an external thread; the threaded sleeve is sleeved between the first rod segment and the second rod segment, and the threaded sleeve is threadedly engaged with the external threads of the first rod segment and the second rod segment respectively, and rotating the threaded sleeve drives the first rod segment and the second rod segment to move closer to or further away from each other.

[0074] One end of the first rod segment is rotatably connected to the movable bracket 10, specifically hinged to the upper end of the stiffening plate 171 of the support base 17, allowing the first rod segment to swing stably around the transverse axis. The other end of the first rod segment is machined with external threads for forming a transmission fit with a threaded sleeve. The end of the second rod segment away from the working platform 2 is also provided with external threads. These external threads can be reverse threads from the external threads on the first rod segment. When reverse threads are used, rotating the threaded sleeve can make the first and second rod segments move synchronously towards or away from each other, improving the length adjustment efficiency.

[0075] A threaded sleeve is fitted between the first and second rod sections. The inner wall of the sleeve is machined with internal threads at corresponding positions to match the external threads of the first and second rod sections, achieving connection through threaded engagement. The outer wall of the threaded sleeve can be provided with knurled texture, a flat bayonet, or a insertion hole, facilitating rotation using tools such as wrenches and handwheels. During rotation, the threaded drive propels the first and second rod sections closer together or further apart, thus achieving continuous stepless adjustment of the overall length of the telescopic rod 22, adapting to work platforms 2 of different sizes and connection point spacings.

[0076] Before assembling the work platform 2, the length of the telescopic rod 22 can be pre-adjusted by rotating the threaded sleeve according to the actual distance between the two mating parts. This ensures that the second connecting part 221 at the end of the second rod segment can be precisely aligned with the corresponding mating part on the work platform 2. After connection, fine adjustments can be made according to the test posture requirements to ensure that the work platform 2 is in a reasonable test posture. This purely mechanical telescopic rod 22 is not easily damaged, is easy to maintain, and has high length adjustment accuracy. It can meet the assembly and adaptation requirements of different work platforms 2. At the same time, it can maintain a fixed length during the test and will not change in length due to force, ensuring the stability of the movement trajectory of the work platform 2 and the authenticity and reliability of the test data.

[0077] Please see Figure 1 and Figure 2 According to some embodiments of this application, the test equipment 1 may also include a plurality of guide rails 30, which extend laterally and are spaced apart longitudinally. The movable support 10 is slidably connected to the guide rails 30 and can move along the guide rails 30.

[0078] Multiple guide rails 30 are arranged extending laterally, with the extension direction of the guide rails 30 being consistent with the arrangement direction of the movable support 10. At the same time, the multiple guide rails 30 are arranged at intervals in the longitudinal direction. The number of guide rails 30 is not specifically limited and can be two, three, four or more. When there are two guide rails 30, the two guide rails 30 are located on both sides of the longitudinal direction of the bottom of the test equipment 1, symmetrically arranged below the movable support 10. When there are three or more guide rails 30, each guide rail 30 is evenly spaced in the longitudinal direction, together providing balanced support for the movable support 10.

[0079] The guide rail 30 can take various forms, such as a linear slide rail, a rectangular guide rail 30, a cylindrical guide shaft, or a T-slot guide rail 30. The guide rail 30 can be directly fixed to the base of the test equipment 1 or the ground foundation. The fixing methods include expansion bolt tightening, pressure plate clamping, welding fixing, etc., to ensure that the guide rail 30 will not shift or loosen during the movement of the movable support 10 and the test stress. The bottom of the movable support 10 slides in conjunction with the guide rail 30. The engagement method can be a sliding block nested with the guide rail 30, a sliding sleeve engaging with the guide shaft, or a roller engaging with the guide rail 30. The sliding engagement structure can reduce the frictional resistance when the movable support 10 moves, making lateral adjustment more effortless and smooth.

[0080] Before testing different work platforms 2, each movable support 10 can be pushed synchronously or separately along the guide rail 30 according to the lateral connection dimensions of the work platform 2. This changes the lateral spacing between adjacent movable supports 10, allowing the connecting components 20 on each movable support 10 to align with the corresponding connection points on the work platform 2, thus completing the adaptation adjustment. The guide rail 30 not only provides reliable motion guidance for the movable supports 10 but also distributes the overall weight of the movable supports 10, connecting components 20, and work platform 2, preventing the movable supports 10 from sinking or shifting under load, and ensuring that the work platform 2 maintains a stable posture and uniform force during the test.

[0081] The guide rail 30 enables the lateral sliding adjustment of the movable support 10. The structure is simple and reliable with high adjustment accuracy. It can quickly adapt to the work platform 2 with different widths and different connection point layouts, further improving the versatility and adaptability of the test equipment 1. At the same time, the guide rail 30 structure is easy to process and install, which helps to reduce the overall manufacturing cost of the test equipment 1 and improve the efficiency of equipment debugging and testing.
