Description

Technical Field

[0001] This utility model relates to the field of space frame structure testing technology, specifically a space frame structure testing and identification device. Background Technology

[0002] A steel space frame structure is a spatial structure composed of multiple members connected at nodes in a specific grid pattern. It offers advantages such as low spatial stress, light weight, high stiffness, and good seismic performance; it can be used as roofs for buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, aircraft hangars, and workshops with large two-way column spacing. The disadvantage is the larger number of members converging at the nodes, making fabrication and installation more complex than with planar structures.

[0003] Traditional steel space frame deflection testing devices suffer from low testing efficiency. Specifically, after the steel space frame is placed in place, the hydraulic mechanism needs to be manually operated to apply pressure point by point. Since the steel space frame has a large area, there are hundreds of nodes that need to be tested, resulting in the testing of a single steel space frame taking tens of hours. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A space frame structure testing and identification device includes a testing mechanism and a transverse moving assembly. The testing mechanism includes a support frame, a crossbeam connected to the support frame, a slider slidably installed inside the crossbeam, a rotary motor connected to the slider, and a pressure frame slidably installed inside the support frame and connected to the output shaft of the rotary motor. The transverse moving assembly includes a drive motor connected to one end of the crossbeam and a threaded rod rotatably installed inside the crossbeam and connected to the output shaft of the drive motor. The slider is screwed to the threaded rod. A support assembly is provided inside the support frame.

[0007] By adopting the above technical solution, the rotating motor drives the output shaft to rotate the pressure frame, so that the long arc surface structure at the bottom of the pressure frame forms a continuous compression test on the top of the steel space frame. The arc surface structure can cover more than ten to dozens of nodes at one time. After the current area is tested, the rotating motor stops working, the pressure frame remains tilted, and then the drive motor drives the slider to move laterally along the cross frame through the threaded rod transmission mechanism, driving the rotating motor and the pressure frame to move to the next test position. This achieves systematic testing of all nodes of the steel space frame, which effectively reduces the testing time of a single steel space frame.

[0008] In a preferred embodiment, the present invention can be further configured such that the length of the pressure frame is less than the inner long side of the support frame, and the pressure frame is made of alloy material.

[0009] In a preferred embodiment, the present invention can be further configured such that the outer edges on both sides of the pressure frame are both arc-shaped.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the supporting assembly includes multiple frame sleeves respectively sleeved on the outside of multiple support legs of the support frame, two rods slidably connected between the support legs of the support frame and the frame sleeves, nuts screwed to the rods, and a support plate connected between two adjacent rods.

[0011] In a preferred embodiment, the present invention can be further configured such that: two nuts are vertically symmetrical about the vertical center plane of the support leg, and the nuts are attached to the outer side of the support leg.

[0012] In a preferred embodiment, the present invention can be further configured such that the tray is set as a triangle, and multiple trays are arranged in a matrix.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the rotating motor drives the output shaft to rotate the pressure frame, so that the long arc surface structure at the bottom of the pressure frame continuously compresses and tests the top of the steel space frame. The arc surface structure can cover more than ten to dozens of nodes at one time. After the current area is tested, the rotating motor stops working, the pressure frame remains tilted, and then the drive motor drives the slider to move laterally along the crossbeam through the threaded rod transmission mechanism, driving the rotating motor and the pressure frame to move to the next testing position. This realizes the systematic testing of all nodes of the steel space frame. This process effectively reduces the testing time of a single steel space frame.

[0015] 2. In this utility model, multiple pallets work together to place the steel grid frame to be tested at the bottom of the pressure frame, ensuring that the pressure frame can smoothly test the top of the steel grid frame. Moreover, after the steel grid frame is tested, by controlling the pressure frame to be placed horizontally, the operator can quickly lift the steel grid frame down, improving the comfort of using this device.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a space frame structure testing and identification device provided by this utility model.

[0029] Example 1:

[0030] Combination Figure 1-5 As shown, the present invention provides a space frame structure testing and identification device, including a testing mechanism 100 and a transverse component 200. The testing mechanism 100 includes a support frame 110, a cross frame 120 connected to the support frame 110, a slider 130 slidably installed inside the cross frame 120, a rotary motor 140 connected to the slider 130, and a pressure frame 150 slidably installed inside the support frame 110 and connected to the output shaft of the rotary motor 140.

[0031] The transverse component 200 includes a drive motor 210 connected to one end of the machine body and the cross frame 120, a threaded rod 220 rotatably installed inside the cross frame 120 and connected to the output shaft of the drive motor 210, a slider 130 screwed to the threaded rod 220, and a support component 300 provided inside the support frame 110.

[0032] Furthermore, the length of the pressure frame 150 is less than the inner long side of the support frame 110. The pressure frame 150 is made of alloy material. The size design of the pressure frame 150 allows it to rotate smoothly on the support frame 110. The use of alloy material ensures the structural strength of the pressure frame 150 and guarantees its service life.

[0033] Example 2:

[0034] Combination Figure 1-3 As shown, based on Embodiment 1, both outer edges of the pressure frame 150 are provided with arc surfaces 400. The arc surfaces 400 prevent the nodes on the steel grid frame from being scratched when the pressure frame 150 presses the steel grid frame.

[0035] Example 3:

[0036] Combination Figure 1 , 4 and Figure 5 As shown, in the above embodiment, the support assembly 300 includes multiple frame sleeves 310 respectively sleeved on the outside of multiple support legs of the support frame 110, two rods 320 slidably connected between the support legs of the support frame 110 and the frame sleeves 310, nuts 330 screwed to the rods 320, and support plates 340 connected between two adjacent rods 320. The multiple support plates 340 cooperate to place the steel mesh frame to be tested at the bottom of the pressure frame 150, ensuring that the pressure frame 150 can successfully test the top of the steel mesh frame.

[0037] Furthermore, the two nuts 330 are vertically symmetrical about the vertical center plane of the support leg of the support frame 110. The nuts 330 are attached to the outside of the support leg of the support frame 110. After unscrewing the nuts 330, the rod 320 can be pulled out from the frame sleeve 310, providing conditions for replacing the support plate 340.

[0038] Furthermore, the support plate 340 is configured as a triangle, and multiple support plates 340 are arranged in a matrix. The matrix arrangement of support plates 340 can stably support the steel space frame.

[0039] The working principle and usage process of this utility model are as follows: The rotating motor 140 and the drive motor 210 work together to achieve continuous detection of the steel space frame nodes. First, the rotating motor 140 drives the output shaft to rotate the pressure frame 150, so that the long arc surface 400 structure at the bottom of the pressure frame 150 forms a continuous compression detection on the top of the steel space frame. Based on its special arc surface 400 design, it can cover more than ten to dozens of nodes at one time. After the detection of the current area is completed, the rotating motor 140 stops working and keeps the pressure frame 150 in an inclined state. Then, the drive motor 210 drives the slider 130 to move laterally along the cross frame 120 through the threaded rod 220 transmission mechanism, which drives the rotating motor 140 and the pressure frame 150 to move as a whole to the next detection position, thereby realizing the systematic detection of all nodes of the steel space frame.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
