[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] A known authorized patent with publication number CN219714688U discloses a scaffolding testing device. Its background art addresses the problem that "current devices for load-bearing capacity testing are large in size and inconvenient to assemble and disassemble, making them difficult to apply flexibly in construction site environments." To address this, the proposed solution includes a lower base, an upper distribution beam, and a connecting plate. The upper distribution beam comprises two main steel beams, two secondary steel beams, and a fixed structure mounted on the main steel beams. The main steel beams are located above the secondary steel beams. The lower base comprises two bottom main beams and two bottom secondary beams. The secondary beams are located on the bottom main beams. The bottom main beams are equipped with a load-bearing device for applying vertical loads, and the load-bearing device is detachably connected to the fixed structure via the connecting plate.

[0004] However, in implementing the relevant technologies, the following problems were found with the above technical solutions: the existing load testing devices usually apply pressure in the vertical direction for testing, which is inconvenient for testing the horizontal lateral force on the scaffold. The testing method is relatively simple and may result in an incomplete testing effect. Utility Model Content

The connecting block is slidably engaged with a moving plate, the other top end of the multi-segment telescopic scissor lift frame is hinged to the moving plate, and one bottom end of the multi-segment telescopic scissor lift frame is hinged to the mounting frame.

Finally, the electric hoist rewinds the rope to perform a horizontal lateral load test. This method achieves both vertical and lateral load testing of the scaffold, avoiding the limitations of a single testing method, ensuring comprehensive testing, and effectively improving the testing results.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1

[0033] Please see Figure 1 - Figure 5 The present invention provides a scaffold load testing device, comprising: a base 1 and a scaffold 2;

[0034] The main controller 3 is fixedly installed at the top corner of the base 1;

[0035] Movable plates 4 are spaced apart on the top of the base 1;

[0036] An adjustment mechanism is provided on the base 1 to drive the moving plate 4 to move horizontally;

[0037] A lifting mechanism is installed on the adjustment mechanism to drive the vertical movement of the moving plate 4;

[0038] The electric hoist body 5 is fixedly installed on the top of the movable plate 4;

[0039] A force sensor 6 is fixedly connected to the end of the rope of the electric hoist body 5. The force sensor 6 is an S-type force sensor, and its model can be selected according to the detection range. For example, a GY-SA type S-type force sensor with a measurement range of 0-3000N is not specified here. Both the force sensor 6 and the electric hoist body 5 are electrically connected to the main controller 3.

[0040] A safety latch 7 is fixedly connected to the top of the force sensor 6;

[0041] The steel wire rope 8 is wrapped around the scaffold 2;

[0042] And connecting rings 9 fixedly connected to both ends of the wire rope 8, with the safety lock 7 and connecting rings 9 locked together.

[0043] The technical solution provided in this embodiment is as follows: In use, the scaffold 2 is erected on the base 1 and fixed thereon. Then, the wire rope 8 is hung on the detection position on the scaffold 2, and the moving plate 4 is moved below the wire rope 8 by the moving mechanism, so that the electric hoist body 5 is aligned with it. At the same time, the rope of the electric hoist body 5 is released to a certain length so that the safety lock 7 and the connecting ring 9 can be connected and locked. Then, the moving plate 4 is moved by the lifting mechanism to adjust the height position, so that the electric hoist body 5 and the wire rope 8 are taut and then stopped. Then, the main controller 3 starts the electric hoist body 5 to rewind, so that the force sensor 6 moves down, and with the cooperation of the safety lock 7 and the connecting ring 9, the wire rope 8 is aligned with the force sensor 6. The scaffold 2 is subjected to a downward pulling force, thereby conducting a vertical load test on the scaffold 2. The data detected by the force sensor 6 is displayed by the main controller 3. When the scaffold 2 is subjected to a horizontal lateral load test, the moving mechanism moves the moving plate 4 out from under the scaffold 2, and the lifting mechanism moves the moving plate 4 upward to keep the electric hoist body 5 and the wire rope 8 horizontal. Then, the electric hoist body 5 is started to rewind the rope to apply a horizontal lateral pulling force to the scaffold 2. Thus, the vertical and lateral load test of the scaffold 2 is achieved, avoiding the situation of a single test method, ensuring the comprehensiveness of the test, and effectively improving the test results.

[0044] Furthermore, the adjustment mechanism includes two electric slides 10 symmetrically fixedly installed on the top of the base 1, and a mounting bracket 11 fixedly installed on the top of the slide block of the electric slide 10. The moving plate 4 is located inside the mounting bracket 11 and slides in cooperation with the mounting bracket 11. The electric slide 10 is a linear module, such as a lead screw module, and is electrically connected to the main controller 3. The mounting bracket 11 is installed on the moving parts of the module, such as a slider or nut seat.

[0045] Specifically, by setting up an electric slide table 10, the mounting frame 11 can be moved horizontally, thereby causing the moving plate 4 and the electric hoist body 5 to move, which facilitates the adjustment of the position of the electric hoist body 5 during lateral test inspection.

[0046] Furthermore, the lifting mechanism includes a multi-segment telescopic scissor lift 12 disposed inside the mounting frame 11, a connecting block 13 hinged to one end of the top of the multi-segment telescopic scissor lift 12, and a power component disposed on the mounting frame 11 for driving the multi-segment telescopic scissor lift 12. The connecting block 13 and the moving plate 4 are slidably engaged. The other end of the top of the multi-segment telescopic scissor lift 12 is hinged to the moving plate 4, and one end of the bottom of the multi-segment telescopic scissor lift 12 is hinged to the mounting frame 11.

[0047] The power components include a motor 14 fixedly mounted on one side of the inner wall of the mounting bracket 11, a lead screw 15 fixedly connected to the output end of the motor 14, and a movable block 16 threadedly connected to the surface of the lead screw 15 and slidably connected to the mounting bracket 11. The movable block 16 is hinged to the other end of the bottom of the multi-segment telescopic scissor lift 12. The motor 14 is electrically connected to the main controller 3.

[0048] Specifically, the motor 14 drives the lead screw 15 to rotate, which in turn moves the movable block 16, enabling the multi-segment telescopic scissor lift 12 to extend and retract. During the extension and retraction of the multi-segment telescopic scissor lift 12, the connecting block 13 slides, thereby causing the movable plate 4 to move up and down within the mounting frame 11 through the multi-segment telescopic scissor lift 12, so as to adjust the height position. During horizontal lateral inspection, the movable plate 4 can be raised to a suitable height to make the inspection points of the electric hoist body 5 and the scaffold 2 parallel. During vertical inspection, the movable plate 4 can be adjusted to a suitable height as needed.

[0049] Example 2

[0050] Based on Embodiment 1, in this embodiment: the base 1 is provided with a fixing mechanism for limiting the position of the scaffold 2.

[0051] The fixing mechanism includes a bidirectional screw 17 rotatably connected to the top of the base 1, a groove formed on the top of the base 1, two connecting brackets 18 threadedly connected to the surface of the bidirectional screw 17 and sliding in the groove, a second motor 19 fixedly mounted on the base 1 and whose output end is connected to the bidirectional screw 17, and a clamping component provided at the end of the connecting brackets 18, wherein the second motor 19 is electrically connected to the main controller 3.

[0052] The clamping components include a U-shaped plate 20 fixedly installed at the end of the connecting frame 18, electric push rods 21 fixedly installed on both sides of the inner wall of the U-shaped plate 20, and an arc-shaped clamping plate 22 fixedly connected to the output end of the electric push rods 21. The electric push rods 21 and the main controller 3 are electrically connected.

[0053] The technical solution provided in this embodiment is as follows: During the test, the scaffold 2 is mounted on the upper side of the connecting frame 18, and the two connecting frames 18 are moved relative to each other by the motor 19 driving the bidirectional screw 17 to adjust the spacing of the arc-shaped clamps 22 according to the width of the scaffold 2. Then, the arc-shaped clamps 22 are moved by the electric push rod 21 so that the arc-shaped clamps 22 contact and clamp with the legs of the scaffold 2, thereby achieving the function of limiting and fixing the scaffold 2 to ensure the stability of the scaffold 2 during the test.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
