Description

Technical Field

[0001] This invention relates to the field of structural strength testing, specifically to a device for testing the structural strength of high-load-bearing matrix steel platforms. Background Technology

[0002] High-load-bearing matrix steel platforms are modularly assembled from multiple independent steel components. Each individual steel component is the fundamental load-bearing unit of the platform, and its structural strength directly determines the overall load-bearing safety and operational stability of the steel platform. They are widely used in heavy-duty industrial operations. During long-term service, individual steel components are prone to deformation, fatigue, cracking, and other damage. The failure of a single component can directly lead to safety hazards for the entire platform. Therefore, accurately detecting the strength parameters of individual steel structures is a core prerequisite for ensuring the safe operation of matrix steel platforms, requiring extremely high accuracy in the test data.

[0003] Currently, the core deficiency of existing steel platform single-unit steel structure strength testing equipment is its low accuracy in single measurements. Existing testing equipment only has a single testing station, and can only acquire one set of test data per test. The testing process is highly susceptible to interference from external factors such as equipment installation errors, point selection deviations, environmental disturbances, and fluctuations in applied stress. The single set of test data is highly random and has high dispersion, making it impossible to effectively avoid testing biases and accurately reflect the actual strength performance of a single steel structure. The lack of comparison and calibration for single data samples means measurement errors cannot be corrected, resulting in insufficient accuracy and reliability of the final test results, failing to meet the core requirement of high-precision testing of single steel structures in high-load-bearing matrix steel platforms.

[0004] In addition, most existing conventional testing equipment adopts a multi-power split structure and lacks a single-power dual-station switching testing structure. It is impossible to calibrate the error by comparing and averaging multiple sets of independent test data. It can only rely on the results of a single test to determine the strength of the component, which further exacerbates the problem of insufficient testing accuracy and cannot effectively solve the industry pain points of low accuracy of single measurement and poor data reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a strength testing device for high-load-bearing matrix steel platform structures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A strength testing device for a high-load-bearing matrix steel platform structure includes a platform on which a support frame is fixedly connected. An upper beam is fixedly connected to the top of the support frame, and a hydraulic cylinder is fixedly connected to the upper beam. Two support frames are symmetrically fixedly connected to both sides below the upper beam. Sliding sleeves are fitted on the outer sides of each support frame, and test beams are fixedly connected to the outer sides of the sliding sleeves. Test components are fixedly connected to the outer sides of each test beam. Locking plates are fixedly connected to the sides of each sliding sleeve. A locking cylinder is fixedly connected to the platform, locking one of the locking plates when the locking cylinder extends or retracts. A positioning column is fixedly connected below the platform, and a mounting base is fixedly connected to the bottom of the positioning column. Two symmetrically arranged lower guide wheels are fixedly connected to the mounting base. Symmetrically distributed upper guide wheels are fixedly connected below the upper beam.

[0007] As a further aspect of the present invention: the first steel cable passes through the equipment platform and slides in cooperation with the equipment platform.

[0008] As a further embodiment of the present invention: when the locking cylinder locks the left locking plate, the hydraulic cylinder extends and pulls the second steel cable to drive the right test beam upward, and the hydraulic cylinder retracts and pulls the first steel cable to drive the right test beam downward.

[0009] As a further embodiment of the present invention: when the locking cylinder locks the right locking plate, the hydraulic cylinder extends and pulls the second steel cable to drive the left test beam upward, and the hydraulic cylinder retracts and pulls the first steel cable to drive the left test beam downward.

[0010] As a further embodiment of the present invention: a locking hole is provided in the middle of the locking plate, and when the locking cylinder extends or retracts, its extension end is inserted into the corresponding locking hole.

[0011] As a further embodiment of the present invention: the test assembly includes a bearing fixed to the end of the test beam and a guide rail fixed to the equipment platform, a slider is slidably connected inside the guide rail, and a clamping unit is rotatably connected to both the bearing and the slider.

[0012] As a further embodiment of the present invention: the clamping unit includes a U-shaped frame, on which two opposing screws are threadedly connected, and clamping plates are fixedly connected to the ends of the screws.

[0013] As a further aspect of the present invention, the contact surface between the clamping plate and the steel is provided with anti-slip texture.

[0014] As a further embodiment of the present invention, it also includes a device rack, on which the device platform is connected.

[0016] Compared with existing technologies, the advantages of this invention are: by setting symmetrically distributed test components on the equipment platform, this invention can perform strength tests using different test components on both sides, thereby obtaining different test results. Averaging the two different test results improves the accuracy of the test results. Furthermore, the device switches test components via a locking cylinder, with a single hydraulic cylinder achieving the testing objectives of different test components, resulting in a high degree of integration.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to the attached diagram. A strength testing device for a high-load-bearing matrix steel platform structure includes a device platform 1, which is mounted on a device frame 25. The device platform 1 allows for overall movement, height adjustment, and fixed-point strength testing, adapting to different application scenarios. The core load-bearing structure of the device is the device platform 1, and all testing structures are integrated and installed on the device platform 1.

[0030] The equipment frame 25 serves as the supporting and movable base for the entire equipment and mainly consists of a chassis 26, a moving handle 27, moving wheels 28, and a telescopic rod 29. The moving handle 27 is fixedly installed on the side of the chassis 26 and, together with multiple moving wheels 28 evenly distributed at the bottom of the chassis 26, allows for the movement of the entire equipment. Simultaneously, the telescopic rod 29 is fixedly mounted on the chassis 26, and the equipment platform 1 is fixed to the top of the telescopic end of the telescopic rod 29. The overall working height of the equipment platform 1 can be flexibly adjusted by the telescopic movement of the telescopic rod 29. The telescopic rod 29 and the chassis 26 can be connected by a sliding connection or a fixed connection. When the chassis 26 and the telescopic rod 29 are connected by a sliding connection, a collar is fixedly connected to the bottom of the telescopic rod 29, and the collar is used to achieve a sliding connection with the chassis 26. At this time, a wing bolt is fixedly connected to the side of the collar. By tightening the wing bolt, the position of the collar is locked, thereby fixing the position of the telescopic rod 29.

[0031] A positioning column 10 is fixedly installed at the bottom of the equipment platform 1. The bottom end of the positioning column 10 is fixedly connected to the mounting base plate 11. To cooperate with the steel cable transmission operation, two lower guide wheels 12 are symmetrically installed on the mounting base plate 11. Correspondingly, two upper guide wheels 13 are symmetrically arranged below the upper beam 3 on the upper part of the equipment. The upper and lower guide wheels cooperate with each other to effectively constrain the steel cable transmission trajectory and reduce transmission friction.

[0032] Two sets of symmetrically arranged support frames 2 are fixedly installed on the upper end of the equipment platform 1. The two sets of support frames 2 are fixed on the left and right sides of the bottom of the upper beam 3, respectively, forming a stable support structure for the upper beam 3. A hydraulic cylinder 4 is fixedly installed on the top surface of the upper beam 3, serving as the core power source for the equipment's testing action and providing continuous power output for the lifting and lowering testing action of the test beam 6. A pulley 14 is fitted at the bottom of the hydraulic cylinder 4. The pulley 14 is wound with a first steel cable 15 and a second steel cable 16, forming a dual-cable independent transmission structure. The first steel cable 15 passes downward through the equipment platform 1 and forms a sliding fit with the equipment platform 1. The end of the first steel cable 15 passes around two lower guide wheels 12 and is finally fixedly connected to the bottom of the test beam 6. The second steel cable 16 is laid upward, passes around two upper guide wheels 13, and is fixedly connected to the top of the test beam 6. By extending and retracting the hydraulic cylinder 4, the pulley 14 is linked, realizing the cable winding and unwinding transmission and driving the test beam 6 to complete the lifting and lowering action.

[0033] Each set of support frames 2 is fitted with a sliding sleeve 5 on its outer side. The sliding sleeve 5 can slide smoothly vertically along the support frame 2, providing guidance and limiting for the lifting and lowering of the test beam 6. The test beam 6 is fixedly welded to the outer side of the sliding sleeve 5 to ensure that the sliding sleeve 5 and the test beam 6 move synchronously and avoid deviation and jamming during the testing process. In order to realize the function of independent operation of the test beam 6 on one side and alternating testing on both sides, a locking plate 8 is fixedly installed on the side of the sliding sleeve 5. At the same time, a locking cylinder 9 is fixedly installed on the equipment platform 1, and a locking hole 17 is opened in the middle of the locking plate 8. In actual operation, through the extension and retraction of the locking cylinder 9, its extension end can be precisely inserted into the locking hole 17 of the corresponding side locking plate 8 to complete the locking and fixing of the sliding sleeve 5 on one side, thereby realizing the locking and positioning of the single-sided testing mechanism and meeting the needs of independent testing on one side.

[0034] The equipment utilizes differentiated locking positioning with locking cylinder 9 to independently control the operation of the left and right test beams 6, allowing for flexible and adjustable testing methods. When locking cylinder 9 locks the left locking plate 8, the left sliding sleeve 5 and test beam 6 are fixed and limited. At this time, hydraulic cylinder 4 extends outward, pulling the second steel cable 16 to drive the right test beam 6 upward. When hydraulic cylinder 4 retracts inward, it pulls the first steel cable 15 to drive the right test beam 6 downward, completing the strength test of the right steel platform structure. Conversely, when locking cylinder 9 locks the right locking plate 8, the right testing mechanism remains fixed, and the extension and retraction of hydraulic cylinder 4 can link with the left test beam 6 to complete the up-and-down reciprocating testing action. Alternating operation on both sides can effectively improve overall testing efficiency and adapt to batch testing production needs.

[0035] To achieve precise clamping and strength testing of the matrix steel platform, test components 7 are mounted on the ends of the test beams 6. Test components 7 mainly consist of a bearing 18, a guide rail 19, a slider 20, and a clamping unit 21. The guide rail 19 is fixedly mounted on the equipment platform 1, and the slider 20 is slidably mounted inside the guide rail 19, allowing for horizontal sliding adjustment of its position along the guide rail 19. The bearing 18 is fixed to the end of the test beam 6, and clamping units 21 are rotatably mounted on both the bearing 18 and the slider 20. These units can adaptively fine-tune the clamping angle according to the installation angle and dimensions of the steel platform, adapting to different testing conditions.

[0036] The fixture unit 21 uses a U-shaped frame 22 as its main structure. Two opposing screws 23 are symmetrically threaded onto the U-shaped frame 22, and a clamping plate 24 is fixedly installed on the inner end of each screw 23. During operation, rotating the screws 23 pushes the clamping plates 24 to move relative to each other, thus clamping and fixing the steel platform profile. Simultaneously, the surfaces of the clamping plates 24 that contact the steel are machined with anti-slip textures, which significantly improves clamping friction and effectively prevents slippage or displacement of the steel during high-strength testing, ensuring the accuracy of the test data and fully meeting the precision and stability requirements of industrial floor testing. Furthermore, other fixture units 21 can be set according to testing needs. For example, if there are holes on the surface of the steel structure, bolts can be directly used to pass through the holes to connect the steel structure to the bearing 18 for fixation.

[0037] In practical use, the clamping unit 21 clamps both ends of the steel structure to be tested. Then, the locking cylinder 9 is activated to lock the locking plate 8 on the other side. This causes the hydraulic cylinder 4 to extend and retract, driving the shaft seat 18 in the clamping unit 21 to move upward. After the shaft seat 18 brings the steel structure to a vertical position, a tensile test can be performed. If a compressive test is required, the steel structure can be placed between the test beam 6 and the equipment platform 1. Then, the compressive test is performed by driving the test beam 6 downward. During the tensile and compressive tests, appropriate pressure sensors and displacement sensors are selected according to the specific steel structure. The specific models can be selected by those skilled in the art based on the test object and existing finished products.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
