Description

Technical Field

[0001] This application relates to the field of support platform technology, and in particular to a support platform for testing the safety performance of a main structure. Background Technology

[0002] With the rapid development of the construction industry, the number of complex structures such as high-rise buildings, bridges, and tunnels is constantly increasing, making the safety performance testing of the main structure particularly important. Testing personnel typically need to operate at heights or in complex structural locations to ensure the stability and safety of the structure. However, these testing environments are often characterized by uneven ground, confined spaces, and complex operations, placing extremely high demands on the stability, flexibility, and safety of the supporting equipment.

[0003] Currently, most support stands on the market use either fixed brackets or simple adjustable brackets. Fixed brackets are usually fixed to the ground by bolts or welding. While they offer high stability, they lack flexibility and are difficult to adapt to different testing environments. Simple adjustable brackets, although offering some height adjustment, often suffer from insufficient stability when facing uneven ground or complex operational requirements.

[0004] During the safety performance testing of the main structure, inspectors often need to operate at heights or in complex structural areas, which places extremely high demands on the stability of the support equipment. However, some existing support platforms lack sufficient stability when facing different testing environments and operational requirements. To improve stability, the supports are usually fixed to the ground, but on uneven ground, the feet at the bottom of the platform cannot make sufficient contact with the ground, making it difficult to set up stably. Utility Model Content

[0005] The purpose of this application is to address the problem that existing support platforms, when facing different testing environments and operational requirements, typically have their supports fixed to the ground. However, on uneven ground, the feet at the bottom of the platform cannot fully contact the ground, making it difficult to erect them stably. This application provides a support platform for testing the safety performance of the main structure.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A support frame for testing the safety performance of a main structure includes a base. Each of the four top corners of the base has a lifting groove, and a lifting rod is inserted into each lifting groove. A worktable is fixedly connected to the top of each lifting rod. Each of the four bottom corners of the base has an adjusting groove, and an adjusting rod is slidably connected inside each adjusting groove. A foot support is fixedly connected to the bottom of each adjusting rod. An adjusting screw is rotatably connected inside each adjusting groove. An adjusting screw groove adapted to the adjusting screw is formed at the top of each adjusting rod. The top of the adjusting screw passes through the base and is fixedly connected to an adjusting knob.

[0008] By adopting the above technical solution, and by setting up the adjustment screw, adjustment groove, adjustment slide rod, and foot support for coordinated use, it is easy to drive the adjustment screw through the adjustment groove and the adjustment slide rod to form a threaded connection by turning the adjustment knob, and push the foot support to move along the length of the adjustment slide rod, so that one end of the foot support comes into contact with the ground, thereby completing the adjustment of the foot support height and ensuring that the foot support comes into contact with the ground, so as to keep the base level on uneven ground.

[0009] Furthermore, an adjustment scale is provided on one side of the adjustment slide.

[0010] By adopting the above technical solution, and by setting up the adjustment scale and the adjustment slide rod in combination, it is easy to show the operator the extension length of the adjustment slide rod, thereby improving the practicality of the device.

[0011] Furthermore, a rubber pad is fixedly connected to the bottom of the foot support.

[0012] By adopting the above technical solution, the friction between the foot support and the ground is effectively increased by setting rubber pads, thereby improving the support stability of the device.

[0013] Furthermore, the base has symmetrically arranged storage slots inside, and an ejector block is rotatably connected to the top of the storage slots. A lifting screw is symmetrically fixed to one end of the worktable. One end of the lifting screw is embedded inside the storage slot and threadedly connected to the ejector block. A lifting assembly is installed at one end of the base.

[0014] By adopting the above technical solution, and by setting up the lifting component to work in conjunction with the receiving slot and the ejector block, the lifting component can be activated to drive the ejector block to rotate, thereby forming a threaded connection between the ejector block and the receiving slot, and pushing the receiving slot to move the worktable along the length of the lifting slide rod. This facilitates precise adjustment of the worktable height to adapt to different testing needs.

[0015] Furthermore, the lifting assembly includes a worm gear fixedly connected to one end of the ejector block, a main shaft rotatably connected to one end of the base, a worm gear meshing with the worm gear symmetrically fixedly connected to one end of the main shaft, a lifting motor fixedly connected to one end of the base, and the output end of the lifting motor fixedly connected to the main shaft.

[0016] By adopting the above technical solution and setting the worm gear and worm to work together, the starting lifting motor drives the main shaft to rotate, which in turn drives the worm gear to mesh with the worm wheel, and the worm wheel drives the ejector block to rotate, thus improving the practicality of the device.

[0017] Furthermore, a through groove is provided at one end of the workbench, and a grid plate is fixedly connected inside the through groove.

[0018] By adopting the above technical solution and using the combination of grid plates and through grooves, the weight of the workbench is effectively reduced, while the anti-slip properties of the workbench surface are improved, ensuring the safety of the testing personnel during operation.

[0019] Furthermore, each of the four bottom corners of the base is fixedly connected with a caster wheel.

[0020] By adopting the above technical solution and using the omnidirectional wheels in conjunction with the base, the base rolls against the ground through the omnidirectional wheels, thereby improving the portability of the base.

[0021] In summary, this application includes at least one of the following beneficial effects:

[0022] 1. By setting up the adjustment screw, adjustment groove, adjustment slide rod, and foot support for coordinated use, it is easy to drive the adjustment screw through the adjustment groove and the adjustment slide rod by turning the adjustment knob, and push the foot support to move along the length of the adjustment slide rod, so that one end of the foot support makes contact with the ground, thereby completing the adjustment of the foot support height and ensuring that the foot support is in contact with the ground to keep the base level on uneven ground.

[0023] 2. By setting up the lifting component to work in conjunction with the receiving slot and the ejector block, the lifting component can be activated to drive the ejector block to rotate, thereby forming a threaded connection between the ejector block and the receiving slot. This pushes the receiving slot to move the worktable along the length of the lifting slide rod, thus facilitating precise adjustment of the worktable height to adapt to different testing needs.

[0029] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0030] This application discloses a support platform for testing the safety performance of a main structure.

[0031] Reference Figure 1 - Figure 3 A support frame for testing the safety performance of a main structure includes a base 1. Each of the four top corners of the base 1 has a lifting groove 2. Lifting rods 3 are inserted into the lifting grooves 2. A worktable 4 is fixedly connected to the top of each of the lifting rods 3. Each of the four bottom corners of the base 1 has an adjusting groove 5. An adjusting rod 6 is slidably connected inside the adjusting groove 5. A foot support 7 is fixedly connected to the bottom of the adjusting rod 6. An adjusting screw 8 is rotatably connected inside the adjusting groove 5. An adjusting screw groove 9, which is adapted to the adjusting screw 8, is opened at the top of the adjusting rod 6. The top of the adjusting screw 8 passes through the base 1 and is fixedly connected to an adjusting knob 10.

[0032] One side of the adjusting slide bar 6 is equipped with an adjusting scale 11;

[0033] Furthermore, a rubber pad 12 is fixedly connected to the bottom of the foot support 7.

[0034] During use, since the ground may be uneven, when placing the base 1 on the ground of the testing area, the operator can rotate the adjustment knob 10 to rotate the adjustment screw 8. The adjustment screw 8 forms a threaded connection with the adjustment groove 9 at the top of the adjustment slide rod 6, and pushes the adjustment slide rod 6 up and down in the adjustment groove 5. This allows the operator to observe the extension length of the adjustment slide rod 6 using the adjustment scale 11 on one side of the adjustment slide rod 6, thereby adjusting the support height of the foot support 7 and ensuring that the foot support 7 is in contact with the ground. This ensures that the base 1 remains level on uneven ground. At the same time, the rubber pad 12 at the bottom of the foot support 7 increases the friction with the ground and prevents the platform from sliding during operation.

[0035] Reference Figure 1 - Figure 3 The base 1 has symmetrically opened storage slots 13 inside, and the top of the storage slots 13 is rotatably connected to the ejector block 14. One end of the worktable 4 is symmetrically fixedly connected to the lifting screw 15. One end of the lifting screw 15 is embedded in the storage slots 13 and threadedly connected to the ejector block 14. One end of the base 1 is equipped with a lifting component.

[0036] The lifting assembly includes a worm gear 16 fixedly connected to one end of the ejector block 14, a main shaft 17 rotatably connected to one end of the base 1, a worm 18 symmetrically fixedly connected to one end of the main shaft 17 and meshing with the worm gear 16, and a lifting motor 19 fixedly connected to one end of the base 1, with the output end of the lifting motor 19 fixedly connected to the main shaft 17.

[0037] In use, after adjusting the level of the base 1, the operator can adjust the height of the worktable 4 through the lifting assembly. First, by starting the lifting motor 19, the main shaft 17 is driven to rotate the worm gear 18, and the worm gear 18 meshes with the worm wheel 16, causing the ejector block 14 to rotate. At the same time, the ejector block 14 forms a threaded connection with the lifting screw 15, thereby driving the lifting screw 15 to push the worktable 4 and move the lifting slide bar 3 along the length of the lifting slide groove 2. This facilitates precise adjustment of the height of the worktable 4 to adapt to different testing needs.

[0038] Reference Figure 1 and Figure 2 One end of the workbench 4 is provided with a through groove 20, and a grid plate 21 is fixedly connected inside the through groove 20.

[0039] In use, the design of the grid plate 21 not only reduces the weight of the workbench 4, but also provides good ventilation and anti-slip properties, ensuring the safety of the testing personnel during operation. At the same time, the hollow structure of the grid plate 21 also facilitates the fixing or connection of testing instruments through the through slots 20.

[0040] Reference Figure 1 and Figure 2 The four corners of the bottom of the base 1 are all fixedly connected with casters 22.

[0041] When in use, if the platform needs to be moved, the operator can push the base 1 to drive the casters 22 to roll along the ground, thereby easily moving the platform to the designated location and effectively improving the portability of the platform.

[0042] The implementation principle of the support platform for testing the safety performance of the main structure in this embodiment is as follows: First, since the ground may be uneven, when the base 1 is placed on the ground of the testing area, the operator can rotate the adjustment knob 10 to drive the adjustment screw 8 to rotate. The adjustment screw 8 and the adjustment groove 9 at the top of the adjustment slide rod 6 form a threaded connection, and push the adjustment slide rod 6 to slide up and down in the adjustment groove 5. In this way, the extension length of the adjustment slide rod 6 can be observed with the adjustment scale 11 on one side of the adjustment slide rod 6 to adjust the support height of the foot support 7, so that the foot support 7 forms contact with the ground to ensure that the base 1 remains level on the uneven ground.

[0043] After adjusting the level of the base 1, the operator can start the lifting motor 19 to drive the main shaft 17 to rotate the worm gear 18, and make the worm gear 18 mesh with the worm wheel 16, which will drive the ejector block 14 to rotate. At the same time, the ejector block 14 will form a threaded connection with the lifting screw 15, thereby driving the lifting screw 15 to push the worktable 4 and move the lifting slide bar 3 along the length of the lifting slide 2, so as to make it easier to accurately adjust the height of the worktable 4.
