[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 The present invention provides an embodiment of a bridge robot base, comprising a support leg 1 and a fixed platform 2. The fixed platform 2 is installed on the upper end of the support leg 1, and a support component 3 is provided on the upper end of the fixed platform 2. The support component 3 includes a fixed base 301, a fixed block 302, a positioning hole 303, a fixing groove 304, a support plate 305, a connecting plate 306, a first connecting hole 307, and a second connecting hole 308.

[0025] The surface of the fixed platform 2 is provided with a fixed base 301, and the interior of the fixed base 301 is provided with a fixed block 302. The surface of the fixed base 301 is provided with several sets of positioning holes 303 at equal intervals in a ring. The fixed block 302 is provided with a fixed groove 304. The surface of the fixed base 301 is provided with eight sets of support plates 305. The upper end of the fixed block 302 is provided with a connecting plate 306. The periphery of the connecting plate 306 is provided with several sets of first connecting holes 307, and the center of the connecting plate 306 is provided with six sets of second connecting holes 308. The lifting function component is installed in the fixed groove 304 and connected to the output end of the lifting function through the second connecting holes 308. At this time, it is connected to the robot on the surface of the connecting plate 306 through the outer first connecting holes 307. When the robot does not need to carry the lifting function, the connecting plate 306 is connected to the support plate 305 through the first connecting holes 307, and the robot is connected to it through the second connecting holes 308. The two sets of holes are used in a reasonable way to install robots with different requirements.

[0026] This device, through the setting of support component 3, solves the problems of limited anti-tilt force of traditional cylindrical robot bases, which may cause the robot to shift or even fall over, and the inefficient use of internal space of cylindrical bases, making it difficult to install components with lifting functions.

[0027] Furthermore, the fixed block 302 has eight sets of movable slots 4 inside, and guide rods 5 are movably connected in the movable slots 4. The upper end of the guide rod 5 is fixedly connected to the connecting plate 306, and the other end of the guide rod 5 is fixedly connected to a limit ring 6. The diameter of the limit ring 6 is adapted to the movable slot 4. Figure 3 As shown, this structure is used to move the guide rod 5 and the limiting ring 6 along the movable groove 4 when the lifting mechanism drives the connecting plate 306 to rise via a robot base equipped with a lifting function, thereby improving the stability of the device.

[0028] Furthermore, a fixed base 301 is fixedly connected to the bottom outer side of the fixed block 302. The support plate 305 is a right-angled trapezoid. The inner walls of the eight sets of support plates 305 are fixedly connected to the outer surface of the fixed block 302, and the bottom is fixedly connected to the fixed base 301. The positioning hole 303 is located between the eight sets of support plates 305, and the position of the first connecting hole 307 corresponds to that of the support plate 305. Figure 2 As shown, this structure is designed to withstand external impacts or high-speed turns by using a robust support plate 305 on the base. The fixed base 301 increases the width and stability of the bottom support, greatly improving the anti-tilt capability and enabling it to cope with lateral forces under various complex working conditions, thus ensuring the stability of the robot.

[0029] Furthermore, a spring 7 is provided at the bottom of the movable groove 4, and a damper 8 is installed inside the spring 7. The upper end of the spring 7 is connected to the bottom of the limiting ring 6, and the lower end of the spring 7 is connected to the bottom of the movable groove 4. Figure 4 As shown, this structure is used to compress the spring 7 and damper 8 when the connecting plate 306 drives the guide rod 5 and the limiting ring 6 to descend, through the setting of the spring 7 and damper 8 in the movable groove 4, which has good stability.

[0030] Furthermore, a protective pad 9 is provided at the bottom of the connecting plate 306, and the protective pad 9 has a certain degree of toughness. For example... Figure 3 As shown, this structure is used to prevent the bottom of the connecting plate 306 from directly contacting the fixed block 302 when the connecting plate 306 is lowered, thereby avoiding wear and improving the service life of the device.

[0031] Furthermore, the positions of the eight sets of movable slots 4 and the eight sets of support plates 305 are staggered, with the movable slots 4 located between the support plates 305. For example... Figure 3 As shown, this structure is used to intersect with the support plate 305 through the opening position of the movable groove 4, so as to avoid affecting the inner diameter of the movable groove 4 when the support plate 305 is under force, thereby causing the inner diameter of the movable groove 4 to change.

[0032] Furthermore, the surface of the fixed platform 2 is provided with holes that match the positioning holes 303. For example... Figure 1 and Figure 2 As shown, the structure is designed to facilitate the installation and removal of the base 301 from the base 2 by opening holes in the surface of the fixing platform 2.

[0033] Working principle: When using, such as Figure 1 As shown, first align the positioning hole 303 with the hole on the surface of the fixing platform 2, and then connect them with bolts, as follows. Figure 2 As shown, based on the robot's usage requirements, it is determined whether a lifting function needs to be installed. If installation is required, the lifting function component is installed in the pre-reserved fixing slot 304 within the fixing block 302, and connected to the output end of the lifting function through the second connecting hole 308. At this time, it connects to the robot on the surface of the connecting plate 306 through the first connecting hole 307 on the outer side. When the robot does not require a lifting function, the connecting plate 306 is connected to the support plate 305 through the first connecting hole 307, and the robot connects to it through the second connecting hole 308. The two sets of holes are used appropriately to install robots with different requirements, such as... Figure 3 and Figure 4 As shown, through the robot base equipped with a lifting function, when the lifting mechanism drives the connecting plate 306 to rise, the guide rod 5 and the limiting ring 6 move along the movable groove 4. Due to the stability of the device, and through the setting of the spring 7 and damper 8 in the movable groove 4, when the connecting plate 306 drives the guide rod 5 and the limiting ring 6 to descend, the spring 7 and damper 8 are squeezed, which has good stability. At the same time as the connecting plate 306 descends to the bottom, the protective pad 9 contacts the top of the fixing block 302, avoiding direct contact between the bottom of the connecting plate 306 and the fixing block 302. The above is the complete working principle of this utility model.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
