[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0023] Example 1

[0024] Reference Figures 1-3 This embodiment provides a leveling single-leg experimental frame, including a column 100, a fixing member 200 on the column 100, a slide groove 101 on the column 100, a fixed pulley group 102 on the top of the slide groove 101, a crossbeam 103 on the slide groove 101, a movable pulley group 104 on the crossbeam 103, a support rod 300 on one side of the column 100, a first fixed pulley 301 on the support rod 300, a load 303 suspended on the first fixed pulley 301 by a rope 302, and the other end of the rope 302 wrapped around the fixed pulley group 102 and the movable pulley group 104.

[0025] Furthermore, there are two columns 100, which are fixed to the ground. The fastener 200 is located between the two columns 100, and a connecting rod is also provided between the two columns 100 to connect them into one unit.

[0026] Specifically, the movable pulley block 104, the fixed pulley block 102, and the corresponding first fixed pulley 301 are all arranged in pairs, close to the two columns 100. In this embodiment, one set of movable pulley block 104 has four pulleys, and one set of fixed pulley block 102 also has four pulleys. Therefore, the crossbeam 103 is suspended by 8 movable pulleys and 16 ropes. Thus, if the load 303 is 1 ton, the crossbeam 103 requires a force of 16 tons to overcome the weight of the load 303 and push the crossbeam 103 downward. Therefore, a 16-ton level test can be achieved using a 1-ton load. It should be noted that the 1:16 force conversion is a theoretical conversion based on the number of movable pulleys. In actual operation, due to the friction of pulleys and rollers, the actual force required is greater than 16 tons. The specific friction value needs to be obtained by specific measurement based on the equipment used. In one example, the actual force was around 18 tons when using pulleys with higher friction. Of course, the existence of friction is not a technical problem that this application needs to solve. It is only necessary to record the actual measured value in the experiment and add the load-bearing force of the example in the test.

[0027] Furthermore, one end of the leveling leg is fixed to the U-shaped plate 202, and the other end rests against the crossbeam 103, causing the leveling leg to extend and push the crossbeam 103 downward to conduct the test.

[0028] The fastener 200 includes a crossbeam 201, and a U-shaped plate 202 is fixed to one side of the crossbeam 201. The U-shaped plate 202 is located above the crossbeam 103.

[0029] The crossbeam 201 is fixed between two columns 100 and extends towards the middle to fix a U-shaped plate 202. The U-shaped plate 202 includes two side plates and a back plate. The two side plates are set on both sides of the back plate, forming a U-shaped structure when viewed from above. Bolt holes are set on the two side plates along the vertical direction. The leveling leg is set in the middle of the U-shaped plate 202 and is fixed by bolts.

[0030] Bolt holes 203 are provided on the side of the U-shaped plate 202.

[0031] The top of the column 100 is provided with a second fixed pulley 105. The rope 302 passes around the first fixed pulley 301 and the second fixed pulley 105 and is connected to the fixed pulley group 102 and the movable pulley group 104.

[0032] Rollers 103a are provided on both sides of the crossbeam 103 and connected to both sides of the slide groove 101.

[0033] The support pole 300 includes a first diagonal pole 304 and a second diagonal pole 305. One end of the second diagonal pole 305 is supported on the ground, one end of the first diagonal pole 304 is connected to the top of the column 100, and the other end of the first diagonal pole 304 is connected to the second diagonal pole 305.

[0034] A crossbar 306 is provided at the connection between the first diagonal bar 304 and the second diagonal bar 305, and the first fixed pulley 301 is fixed on the crossbar 306.

[0035] Specifically, refer to Figure 1 The load 303 is suspended on the rope 302. The rope 302 passes around the first fixed pulley 301 and the second fixed pulley 105 and is wound around the side movable pulley. Then it is wound around the fixed pulley and the movable pulley in sequence. Finally, it passes around the last fixed pulley and is fixed to the column 100, realizing the application of the movable pulley group and achieving the effect of using a small weight to conduct a large weight level test.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
