Technical Field

[0001] This utility model relates to the field of industrial equipment installation, specifically an adjustable support base. Background Technology

[0002] In the field of industrial equipment installation, support bases are crucial components for ensuring stable equipment operation. Current technologies typically employ fixed structures (such as welded or bolted types), which prevent adjustment of the support point position and height, leading to the following drawbacks:

[0003] 1. Limited application scenarios: When there are deviations in the installation location of the equipment or the flatness of the ground, traditional support bases cannot be adapted, and additional shims or redesign of the installation base are required, resulting in high construction costs;

[0004] 2. Low adjustment efficiency: Although some adjustable support bases are equipped with threaded adjustment mechanisms, manual repeated tightening of bolts is required, resulting in low adjustment accuracy and long adjustment time. Utility Model Content

Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-2As shown, an adjustable support base includes a base 14, a frame 11, a support plate 7, a lead screw telescopic mechanism 16, and an adjustment mechanism. The adjustment mechanism includes a worm gear reducer 3, a handwheel 4, and a positioning assembly. The worm gear reducer 3 is fixed to the frame 11 via a reducer mounting base 15, and its output end is connected to the lead screw telescopic mechanism 16. The handwheel 4 is connected to the input end of the worm gear reducer 3 via a connecting shaft 17. The support plate 7 is slidably connected to the frame 11 via a guide shaft 6, and the telescopic end of the lead screw telescopic mechanism 16 is connected to the support plate 7. The positioning assembly includes a positioning screw 22, a positioning nut 20, a positioning handwheel 19, a positioning plate 23, and a nut mounting base 21. The positioning nut 20 is installed in the nut mounting base 21, the positioning screw 22 passes through the positioning nut 20 and is connected to the positioning handwheel 19, and the lower end of the positioning screw 22 is inserted into the inner hole of the positioning plate 23. The positioning plate 23 is fixed to the base 14. The rotating positioning handwheel 19 drives the positioning screw 22 to press down the positioning plate 23, thereby fixing the position of the frame through friction.

[0025] One end of the connecting shaft 17 is connected to the input shaft of the worm gear reducer 3 via a coupling 18, and the other end is connected to the handwheel 4 via a first fixed seat 5. Buffers 2 are provided on both sides of the support plate 7. The buffers 2 are fixed to the four corners of the base 14 via buffer mounting seats 12, and the buffers 2 are fixedly connected to the buffer mounting seats 12 via limit bolts 1. The buffers effectively reduce the impact of the frame on the base during the movement of the support plate. The guide shaft 6 is connected to the frame 11 via a linear bearing 10; the guide shaft 6 is fixedly connected to the support plate 7 via a second fixed seat 9. A linear guide rail 13 is also installed at the bottom of the frame 11. The linear guide rail 13 slides in conjunction with the guide rail groove on the base 14 to realize the movement of the support plate 7. The support plate 7 and the screw telescopic mechanism 16 are connected via a telescopic mechanism mounting seat 8. The worm gear reducer 3 and the lead screw telescopic mechanism 16 constitute a first-stage reduction and torque amplification system. The input torque of the handwheel 4 is transmitted through the coupling 18, which drives the lead screw telescopic mechanism 16 to realize the vertical lifting and lowering of the support plate 7.

[0026] In use, first install the support base of this utility model at the position where support is needed. Since the support part is a planar support plate 7, it can provide more support points. Push the frame 11 to move the support plate 7 to the appropriate position, and then rotate the handwheel 4 to support the support plate 7 on the required support point to achieve support for the object being supported.
