Description

Technical Field

[0001] The utility model relates to the technical field of robot bases, in particular to a support base for an inspection robot. Background Art

[0002] Inspection robots refer to automated equipment used to automatically patrol specific areas or facilities for the purpose of monitoring, inspection and maintenance. They are widely used in power systems (such as transmission lines and substations), petroleum and petrochemicals, rail transportation, campus security and other fields. With the advancement of technology, inspection robots are becoming more and more intelligent, and can complete inspection tasks efficiently and accurately in complex environments, greatly improving work efficiency and safety. In order to enable inspection robots to perform better inspection operations, they are usually equipped with a support base, which not only facilitates production and installation, but also provides a more stable mobile platform for the robot.

[0003] For example, the patent with announcement number CN219563082U discloses a power inspection robot base, including a base body, an inspection robot body mounted on top of the base body, four moving wheels connected to the base body, a drive assembly mounted inside the base body for driving the four moving wheels, an anti-collision strip mounted on the outside of the base body, and an upper seat and a lower seat. The upper seat is connected to the inspection robot body, a battery is mounted inside the upper seat, and the moving wheels and the drive assembly are mounted inside the lower seat. The upper and lower seats are detachably connected. By providing a split base, the moving wheels, drive device, and anti-collision strip are connected to the lower seat. When the inspection robot body can operate normally but the moving wheels cannot move, the lower seat can be removed and repaired, and then replaced with a new lower seat so that the device can continue to be used, thereby solving the technical problems existing in the prior art.

[0004] However, the robot base in the above technology still has the following problems:

[0005] Although the detachable structure separates the driving mechanism from the robot, making it easier to replace and maintain the driving mechanism of the robot, this split design increases the overall height of the robot to a certain extent, causing the center of gravity of the robot to move upward. When walking on a slope or when one side of the moving wheel presses on stones or obstacles on the road, the position of the moving wheel on one side will be too high, which will cause the robot to tilt to one side and roll over, resulting in poor walking stability. Utility Model Content

[0006] In response to the deficiencies of the existing technology, the present invention provides a support base for an inspection robot. For example, by changing the center of gravity of the base, the robot is less likely to roll over when a certain tilt angle occurs, thereby improving the walking stability of the robot.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support base for an inspection robot, comprising a mounting base installed at the bottom of the robot, the mounting base being provided with a cavity, the bottom surface of the cavity being slidably connected to a counterweight block, the upper surface of the counterweight block being connected to a driving rod, the two ends of the driving rod being respectively connected to the inner walls on both sides of the cavity in the mounting base, the bottom surface of the driving rod being fixedly connected to a limiting bar, a limiting groove being provided on the side of the counterweight block close to the limit bar, both ends of the limit groove being opened through, the limit bar being slidably connected to the limit groove, the top of the counterweight block being connected to a driving mechanism, the other end of the driving mechanism being connected to the driving rod, for driving the counterweight block to move laterally below the driving rod.

[0008] Furthermore, the length of the limiting strip is equal to the length of the driving rod.

[0009] Furthermore, the driving mechanism includes a driving motor and a gear. The driving motor is fixedly connected to the upper surface of the counterweight through a mounting seat. The gear is fixedly connected to the output end of the driving motor. A plurality of tooth grooves are provided on the side of the driving rod away from the counterweight. The plurality of tooth grooves extend from one end of the driving rod to the other end and are evenly distributed, and the gear is engaged with the tooth grooves.

[0010] Furthermore, both ends of the driving rod are fixedly connected with sliders, and the inner walls on both sides of the cavity are provided with sliding grooves. The two sliders are slidingly connected to the two sliding grooves respectively, and the inner wall at one end of the cavity is connected with a telescopic part, and the other end of the telescopic part is connected to the driving rod.

[0011] Furthermore, the telescopic member is an electric push rod, which is fixedly connected to the inner wall of one end of the cavity, and the output end of the electric push rod is fixedly connected to the driving rod, and the electric push rod is located above the counterweight block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This type of inspection robot uses a support base, and the driving mechanism can move the counterweight block on the driving rod, thereby moving the counterweight block in the cavity of the mounting base, and then changing the center of gravity of the mounting base, so that the inspection robot is less likely to roll over when walking on an inclined road.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1 - Figure 5 A support base for an inspection robot includes a mounting base 1 installed at the bottom of the robot. The mounting base 1 is provided with a cavity 101. The bottom surface of the cavity 101 is slidably connected to a counterweight 2. The upper surface of the counterweight 2 is connected to a driving rod 3. The two ends of the driving rod 3 are respectively connected to the inner walls on both sides of the cavity 101 in the mounting base 1. The bottom surface of the driving rod 3 is fixedly connected to a limiting bar 4. A limiting groove 201 is provided on the side of the counterweight 2 close to the limiting bar 4. Both ends of the limiting groove 201 are penetrated. The limiting bar 4 is slidably connected to the limiting groove 201. The top of the counterweight 2 is connected to a driving mechanism. The other end of the driving mechanism is connected to the driving rod 3, which is used to drive the counterweight 2 to move laterally below the driving rod 3.

[0022] like Figure 1 - Figure 5 As shown, the support base for an inspection robot in the present invention is similar in structure to the support base for an existing inspection robot, such as a power inspection robot base disclosed in the patent with announcement number CN219563082U. The main improvement of the present invention is that the possibility of the inspection robot tipping over can be reduced by changing the center of gravity of the base, thereby further improving the walking stability of the robot. Figures 1 to 5As shown, when the support base for the inspection robot in the present invention is in use, the driving mechanism on the mounting base 1 is connected to the horizontal system of the inspection robot. When the inspection robot walks on an uneven road surface, the horizontal system detects that the inspection robot tilts to one side, and then controls the driving mechanism to drive the counterweight block 2 to move under the driving rod 3, and moves the counterweight block 2 to the higher side of the inclined mounting base 1, so that through the weight of the counterweight block 2, the center of gravity of the mounting base 1 together with the inspection robot installed above is transferred to the higher part of the inclined surface, so that the inspection robot is not prone to rollover when walking on the inclined road surface, and the walking stability of the inspection robot is further improved.

[0023] like Figure 1 - Figure 5 As shown, the length of the limit bar 4 is equal to the length of the driving rod 3. Since the counterweight 2 needs to slide at the bottom of the driving rod 3, setting the length of the limit bar 4 equal to the length of the driving rod 3 can ensure that the counterweight 2 can move left and right under the driving rod 3 without being separated from the driving rod 3.

[0024] like Figure 1 - Figure 5 As shown, the drive mechanism includes a drive motor 5 and a gear 6. The drive motor 5 is fixedly connected to the upper surface of the counterweight 2 through a mounting base. The gear 6 is fixedly connected to the output end of the drive motor 5. A plurality of tooth grooves 301 are formed on the side of the drive rod 3 away from the counterweight 2. The plurality of tooth grooves 301 extend from one end of the drive rod 3 to the other end and are evenly distributed. The gear 6 engages with the tooth grooves 301. When the leveling system inside the inspection robot detects that the inspection robot is tilting to one side, the control starts the drive motor 5, driving the gear 6 to rotate. When the gear 6 rotates, through engagement with the tooth grooves 301 on the drive rod 3, when both ends of the drive rod 3 are fixed in the cavity 101, the rotation of the gear 6 drives the drive motor 5 to move laterally on the drive rod 3. The drive motor 5 drives the counterweight 2 fixed below to slide laterally below the drive rod 3, thereby completing the movement of the counterweight 2, and then changing the center of gravity of the mounting base 1, making it less likely for the inspection robot to tilt and tip over.

[0025] like Figure 1 - Figure 5As shown, both ends of the driving rod 3 are fixedly connected with sliders 7, and the inner walls on both sides of the cavity 101 are provided with slide grooves 102. The two sliders 7 are slidably connected to the two slide grooves 102 respectively. The inner wall at one end of the cavity 101 is connected with a telescopic member, and the other end of the telescopic member is connected to the driving rod 3. When the mounting base 1 together with the inspection robot installed above moves up and down on the slope, the telescopic member can drive the driving rod 3 to move back and forth in the cavity 101, and then drive the counterweight 2 to move back and forth in the cavity 101, so that the center of gravity moves back and forth in the mounting base 1, so that the mounting base 1 together with the installed inspection robot is not prone to rolling back and forth. The driving rod 3 can maintain the horizontal movement of the driving rod 3 forward and backward through the sliding of the sliders 7 at both ends and the slide grooves 102 on both sides to avoid tilting and misalignment. The telescopic member is also connected and controlled by the horizontal system in the inspection robot.

[0026] like Figure 1 - Figure 5 As shown, the telescopic member is an electric push rod 8, which is fixedly connected to the inner wall of one end of the cavity 101. The output end of the electric push rod 8 is fixedly connected to the drive rod 3. The electric push rod 8 is located above the counterweight 2. By starting the electric push rod 8, the drive rod 3 is driven to move back and forth, and then the counterweight 2 is driven to move back and forth in the cavity 101, completing the center of gravity transfer of the mounting base 1. The electric push rod 8 is located above the counterweight 2, which can prevent the electric push rod 8 from colliding with the counterweight 2 below when pushing and pulling the drive rod 3.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
