[0002] The technical background of height positioning frames stems from the need for precise height positioning in various engineering and industrial applications. Traditional manual adjustment is labor-intensive and inefficient, requiring height positioning devices to improve efficiency. In pipeline construction, to ensure the quality of steel pipe connection, the height of steel pipes of different diameters needs to be adjusted. In the field of photovoltaic power generation, height positioning frame technology is also needed to solve the problem of inconvenient height adjustment of existing photovoltaic rooftop power generation positioning frames. When machining centers process parts of different sizes, they also need height positioning fixtures to avoid interference and improve processing efficiency.

[0003] Height positioning frames are used in various engineering and industrial scenarios by adjusting a mobile platform to different heights and then fixing it. However, in practical applications, the device relies on manual adjustment. When facing scenarios with large loads and high-frequency adjustments, the operation is time-consuming and labor-intensive, resulting in low efficiency, increased costs, reduced safety and practicality, and a narrowed scope of application.

[0034] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6The lifting mechanism 2 includes a baffle 210. The top of the baffle 210 is fixedly connected to the bottom of the base 5. Multiple hollow tubes 203 are fixedly connected to the four corners of the bottom of the base 5. Support columns 209 are slidably connected to the inner wall of the hollow tubes 203. A spring 206 is fixedly connected to the top of the support column 209. A base plate 205 is fixedly connected to the bottom of the support column 209. Multiple guide grooves 208 are opened on the outer wall of the baffle 210. A pin 207 is slidably connected to the inner wall of the guide groove 208. A rotating shaft 201 is rotatably connected to the middle of the inner wall of the baffle 210. A limit gear 202 is fixedly connected to the outer wall of the rotating shaft 201. A cam 204 is fixedly connected to an adjacent end of the rotating shaft 201.

[0035] Specifically, the baffle 210 can protect the lifting mechanism 2, the hollow tube 203 can prevent the spring 206 from bending and deforming during the stretching and contraction process, the rotating shaft 201 can drive the limit gear 202 and the cam 204 to rotate together to adjust the height of the mechanism, and the pin 207 can limit the cam 204 to a fixed angle to stably fix the mechanism at the required height.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The top of the guide rail 15 is fixedly connected to a guardrail 1, the two ends of the support rod 14 are threaded with anti-loosening nuts 4, the inner wall of the guardrail 1 is fixedly connected with multiple safety buckles 12, the left side of the guardrail 1 is fixedly connected with a ladder 9, the top of the base 5 is fixedly connected with a protective cover 11, and the top of the protective cover 11 is provided with a ventilation opening 13.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 A hinge 24 is fixedly connected to the outer wall of the protective cover 11, a control box 8 is fixedly connected to the outer wall of the protective cover 11, a tire frame 25 is fixedly connected to the bottom of the base 5, a wheel 6 is rotatably connected to the inner wall of the tire frame 25, a control box 8 is fixedly connected to the top of the base 5 near the edge, and a nameplate 7 is fixedly connected to the outer wall of the motor 22.

[0039] Specifically, hinge 24 can open the protective cover 11 for easy maintenance and repair, control box 8 can control the start and stop of motor 22, and wheels 6 and tire rack 25 allow the device to move for easy transportation.

[0040] Working principle: When the motor 22 is turned on, the motor 22 drives the first transmission bevel gear 21 to rotate, the first transmission bevel gear 21 drives the second transmission bevel gear 23 to rotate, and then drives the transmission threaded rod 10 to rotate. The slider 20, which is connected to the transmission threaded rod 10, will move left and right on the slide rail 19, so that the bracket 3 extends to both sides with the middle support rod 14 as the center. The guide rail 15 will also move up and down due to the extension of the bracket 3, thereby achieving the purpose of adjusting the height.

[0041] Rotating the shaft 201 causes the cam 204 and the limiting gear 202 to rotate together. The rotation of the cam 204 pushes out the bottom plate 205, supporting it on the ground. When the appropriate height is reached, insert the pin 207 from the guide groove 208 into the limiting gear 202, which is fixedly connected to the cam 204, so that the cam 204 is fixed and does not rotate. Pull out the pin 207, and the spring 206 in the first hollow tube 203 and the support column 209 will retract, restoring the bottom plate 205 and the cam 204 to their original positions.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
