[0034] In order to solve the problems in the prior art, the present application provides a lifting mechanism and a patrol robot platform, which can effectively avoid the problem that the precision and stability of the lifting mechanism and the patrol robot platform are deteriorated due to wear of the guide member.

[0035] As shown in FIG. 1, Figures 1-7 The embodiments of the present application provide a lifting mechanism, which comprises a telescopic assembly 1, a guide assembly 2 and a drive assembly 3.

[0036] The telescopic assembly 1 is telescopic along a first direction X, and the telescopic assembly 1 comprises a plurality of sleeves 11 arranged in sequence. Specifically, the first direction X is a vertical direction, and the telescopic assembly 1 is telescopic along the first direction X through the plurality of sleeves 11 arranged in sequence.

[0037] The guide assembly 2 is arranged between two adjacent sleeves 11, and the guide assembly 2 comprises a fixed plate 21 and a rolling element 22 rotatably arranged on the fixed plate 21. The fixed plate 21 is connected with one of the two sleeves 11, and the rolling element 22 abuts against the other sleeve 11.

[0038] The drive assembly 3 is arranged at one end of the telescopic assembly 1, and a movable end of the drive assembly 3 is connected with the other end of the telescopic assembly 1, for driving the telescopic assembly 1 to telescope along the first direction X.

[0039] In the present application, the telescopic assembly 1 is driven to telescope along the first direction X by the drive assembly 3, and the guide assembly 2 is arranged between two adjacent sleeves 11 of the telescopic assembly 1. The fixed plate 21 of the guide assembly 2 is connected with the side wall of one of the sleeves 11, and the rolling element 22 of the guide assembly 2 abuts against the side wall of the other sleeve 11. When the two sleeves 11 slide relative to each other, the rolling element 22 rotates to guide the two sleeves 11, which can effectively avoid the problem that the precision and stability of the lifting mechanism and the inspection robot platform are deteriorated due to abrasion.

[0040] In the related art, in order to ensure the precision of the telescopic assembly 1 during telescoping and the structural stability of the telescopic assembly 1 in the fully extended state, a guide sheet is arranged between the sleeves of the telescopic assembly 1. However, the sliding friction between the sleeves of the telescopic assembly 1 and the guide sheet during telescoping will make the guide sheet thinner and thinner. When the gap between the sleeves becomes larger, the precision of the telescopic assembly 1 during telescoping will be affected, the telescopic assembly 1 will shake during telescoping, and the structural stability of the telescopic assembly 1 in the fully extended state will also be affected, thereby affecting the precision of the camera robot during movement.

[0041] In the present application, the guide assembly 2 is arranged between two adjacent sleeves 11, and the guide assembly 2 comprises a fixed plate 21 connected with the side wall of one of the sleeves 11 and a rolling element 22 arranged on the fixed plate 21 and abutting against the side wall of the other sleeve 11. During telescoping of the telescopic assembly 1, the rolling of the rolling element 22 replaces the original sliding, thereby effectively reducing the abrasion of the guide assembly 2, prolonging the service life of the guide assembly 2, ensuring the precision of the telescopic assembly 1 during telescoping and the structural stability of the telescopic assembly 1 in the fully extended state, and further ensuring the precision of the camera robot during movement.

[0042] In some embodiments, the installation gap 12 is formed between two adjacent sleeves 11, and a plurality of guide assemblies 2 are arranged in the installation gap 12 and are evenly arranged in the circumferential direction.

[0043] In the present application, the installation gap 12 is formed between two adjacent sleeves 11, and the guide assembly 2 is arranged in the installation gap 12, and a plurality of guide assemblies are evenly arranged in the circumferential direction, so that the two adjacent sleeves 11 can be limited and guided from multiple directions, further ensuring the accuracy and structural rigidity of the telescopic assembly 1 during extension and contraction.

[0044] In an embodiment, the installation gap 12 is an annular structure, and the guide assembly 2 is an arc structure.

[0045] In the present application, the sleeve 11 is a cylinder, and the adjacent sleeves 11 have different inner diameters, so as to realize the nesting of the sleeves 11, and the plurality of sleeves 11 are arranged with the same center, so that the installation gap 12 between the two sleeves 11 is an annular structure with equal width, and the guide assembly 2 is an arc structure and is evenly distributed in the installation gap 12 to limit and support the two adjacent sleeves 11.

[0046] Specifically, the guide assembly 2 of the installation gap 12 between the two sleeves 11 is more than 3 groups, which can ensure the guiding accuracy between the two sleeves 11.

[0047] In another embodiment, the installation gap 12 is a frame structure, and the guide assembly 2 is provided with four groups, and the four groups of guide assemblies 2 are arranged on the four sides of the installation gap 12.

[0048] In the present application, the cross section of the sleeve 11 is square, the installation gap 12 between the two sleeves 11 is a frame structure, the guide assembly 2 is provided with four groups, and the four groups of guide assemblies 2 are arranged on the four sides of the installation gap 12, wherein two opposite guide assemblies 2 guide and right the sleeve 11 along the length direction, and the other two opposite guide assemblies 2 guide and right the sleeve 11 along the width direction, so that the sleeve 11 can be righted from four sides, and the accuracy and structural stability of the telescopic assembly 1 during extension and contraction are ensured.

[0049] In some embodiments, the fixed plate 21 includes a first fixed plate 211 and a second fixed plate 212, the rolling member 22 includes a first rolling member 221 rotatably arranged on the first fixed plate 211 and a second rolling member 222 rotatably arranged on the second fixed plate 212, and the first fixed plate 211 and the second fixed plate 212 are respectively connected with the side walls of the two adjacent sleeves 11; wherein, when the telescopic assembly 1 is extended to the limit length, the first fixed plate 211 abuts against the second fixed plate 212.

[0050] Specifically, two first fixing plates 211 and two second fixing plates 212 are arranged on one side of the sleeve 11, the two first fixing plates 211 are arranged in a horizontal direction and are spaced apart, and the two second fixing plates 212 are arranged in a horizontal direction and are spaced apart, so that the two sleeves 11 can be kept in a vertical state after the first fixing plate 211 and the second fixing plate 212 abut, thereby ensuring the structural stability of the telescopic assembly 1.

[0051] In the present application, the two adjacent sleeves 11 include an outer sleeve 11 located on the outer side and an inner sleeve 11 located on the inner side, wherein the first fixing plate 211 is arranged on the inner surface of the outer sleeve 11, and the first rolling member 221 is arranged on the first fixing plate 211 and abuts against the outer surface of the inner sleeve 11; the second fixing plate 212 is arranged on the outer surface of the inner sleeve 11, and the second rolling member is arranged on the second fixing plate 212 and abuts against the inner surface of the outer sleeve 11, which can double-position the two adjacent sleeves 11, thereby further improving the accuracy and structural stability of the telescopic assembly 1 during the telescopic process. In addition, when the telescopic assembly 1 is fully extended, the end of the first fixing plate 211 abuts against the end of the second fixing plate 212, thereby playing a limiting role and preventing the telescopic sleeve from continuing to extend and falling off.

[0052] In some embodiments, the surface of the fixing plate 21 is arranged in a matrix with a plurality of mounting grooves 213, and the plurality of rolling members 22 are respectively embedded in the plurality of mounting grooves 213.

[0053] In the present application, the fixing plate 21 is arranged in a matrix with a plurality of mounting grooves 213, and the rolling member 22 is arranged in the mounting groove 213 and can roll in the mounting groove 213, so that the plurality of rolling members 22 can abut against the sleeve 11 and play a guiding role, thereby further improving the accuracy and structural stability of the telescopic assembly 1 during the telescopic process.

[0054] As shown in Figure 6 In some embodiments, the mounting groove 213 is provided with an elastic support 23 for supporting the rolling member 22, so that part of the rolling member 22 extends to the outside of the mounting groove 213.

[0055] In the present application, by arranging the elastic support 23 in the mounting groove 213, the rolling member 22 can be supported, so that the rolling member 22 can abut against the side wall of the sleeve 11, thereby playing a guiding and righting effect.

[0056] Specifically, the elastic support 23 comprises opposite first and second ends 231 and 232 and an elastic bending portion 233 connecting the first and second ends 231 and 232, and the elastic support effect is realized through the elastic bending portion 233, wherein the first end 231 abuts against the rolling member 22, and a groove matched with the outer shape of the rolling member 22 is arranged at the first end 231 to increase the contact area between the elastic support 23 and the rolling member 22, so as to avoid that the normal rolling of the rolling member 22 is affected due to the small contact area between the elastic support 23 and the rolling member 22, and the smoothness of the rolling of the rolling member 22 is ensured.

[0057] As shown in Figures 6-7 In some embodiments, the guide assembly 2 further comprises an adjusting member 24, the adjusting member 24 comprises an adjusting bolt 241 threadedly connected with the fixed plate 21 and an adjusting plate 242 arranged at the abutting position of the adjusting bolt 241, one side of the adjusting plate 242 abuts against the second end 232 of the elastic support 23, and the adjusting plate 242 can be adjusted horizontally by rotating the adjusting bolt 241, so as to adjust the extrusion force of the adjusting plate 242 on the elastic support 23, the abutting force between the rolling member 22 and the sleeve 11 is adjusted by changing the elastic change amount of the elastic support 23, the elastic force of the elastic support 23 is prevented from being too large to affect the smoothness of the rolling of the rolling member 22, and the elastic force of the elastic support 23 is also prevented from being too small to provide better support, so that the sleeves 11 are prevented from shaking.

[0058] Specifically, one adjusting plate 242 corresponds to a plurality of elastic supports 23, that is, the compression amount of the plurality of elastic supports 23 can be adjusted by one adjusting plate 242, and an adjusting hole is arranged on the side wall of the sleeve 11, the adjusting hole corresponds to the adjusting bolt 241, so as to facilitate the rotation of the adjusting bolt 241.

[0059] In some embodiments, the rolling member 22 is a ball or a roller.

[0060] In the present application, the rolling member 22 is a ball, and the rolling of the ball in the installation groove 213 realizes the guiding of the two sleeves 11; the rolling member 22 can also be a roller, the ball is arranged in the horizontal direction, and the rolling of the roller realizes the guiding of the two sleeves 11.

[0061] In some embodiments, the telescopic assembly 1 further comprises a limiting frame 13 arranged at the bottom of the sleeve 11, and the limiting frame 13 is used for limiting the adjacent two sleeves 11.

[0062] In the present application, the limiting frame 13 is fixed at the bottom of the sleeve 11 by a fastener, and the adjacent two sleeves 11 can be limited by the limiting frame 13, so as to prevent the two sleeves 11 from being disengaged.

[0063] Specifically, the limiting frame 13 is arranged at the bottom of the outer sleeve 11, and limits the adjacent inner sleeve 11 inside the outer sleeve 11, so as to prevent the inner sleeve 11 from falling off.

[0064] The lifting mechanism drives the telescopic assembly 1 to extend and retract along the first direction X through the driving assembly 3, and the telescopic assembly 1 is guided between the adjacent two sleeves 11 through the guiding assembly 2. The fixed plate 21 of the guiding assembly 2 is connected with the sidewall of one of the sleeves 11, and the rolling piece 22 of the guiding assembly 2 abuts against the sidewall of the other sleeve 11. When the relative sliding between the two sleeves 11 occurs, the rolling piece 22 guides the two sleeves 11 by rotating itself, which can effectively avoid the problem that the precision and stability of the lifting mechanism and the inspection robot platform are deteriorated due to abrasion.

[0065] The embodiment of the present application provides an inspection robot platform, which comprises the lifting mechanism and a guide rail arranged at one end of the lifting mechanism.

[0066] In the present application, the guide rail is connected by the ends of the plurality of lifting mechanisms, and the lifting of the guide rail is completed through the synchronous lifting of the plurality of lifting mechanisms. After the height of the guide rail is adjusted, the camera robot moves along the guide rail, thereby completing the inspection work.
