Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, and in particular to a support base for an inspection robot. Background Technology

[0002] Inspection robots are wheeled or tracked robots that integrate multiple sensors. With intelligent inspection technology as the core, they integrate robot body technology, non-contact detection technology for power equipment, multi-sensor fusion technology, navigation and behavior planning technology, etc., and can replace humans to complete inspection tasks in complex environments.

[0003] A search revealed that Chinese Patent Publication No. CN222661809U discloses a support base for an inspection robot, including a mounting base installed on the bottom of the robot. This support base for the inspection robot can move a counterweight on a drive rod through a drive mechanism, thereby moving the counterweight within the cavity of the mounting base, thus shifting the center of gravity and making the inspection robot less prone to tipping over on inclined surfaces.

[0004] However, considering that the weight of its counterweight is fixed, in actual inspection work, the robot may need to carry inspection equipment of different weights depending on the task requirements. The fixed weight counterweight is difficult to provide sufficient balance, and the robot's center of gravity is seriously offset. It is very easy for the robot to tip over during walking and turning, which threatens the safety of surrounding personnel and may even cause secondary accidents, resulting in greater losses. On the other hand, when carrying lighter equipment, the excessively heavy fixed counterweight will increase the robot's energy consumption and operating burden, reduce energy efficiency and working endurance. Therefore, a support base for inspection robots is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a support base for inspection robots, which aims to solve the problem that in actual inspection work, due to task requirements, robots need to carry inspection equipment of different weights. If the weight of the counterweight is fixed, it is difficult to provide sufficient balance according to the weight changes of the equipment, resulting in a serious shift in the robot's center of gravity. This makes the robot prone to tipping over when walking or turning, threatening the safety of surrounding personnel and even causing secondary accidents. Moreover, when carrying lighter equipment, an excessively heavy fixed counterweight will increase the robot's energy consumption and operating burden, reducing energy efficiency and working endurance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a support base for an inspection robot, comprising the support base, a counterweight seat slidably connected to the inner surface of the support base, a counterweight plate inserted into the top of the outer surface of the counterweight seat, a limit frame hinged to the rear of the outer surface of the counterweight seat, the bottom of the inner surface of the limit frame contacting the top of the outer surface of the counterweight plate, and a snap-fit ​​component provided on the inner surface of the counterweight seat.

[0007] The locking assembly includes a locking block, the outer surface of which is slidably connected to the front of the inner surface of the counterweight seat, the outer surface of which is elastically connected to the front of the inner surface of the counterweight seat via a spring, the top of the outer surface of which is locked to the front of the inner surface of the limiting frame, a lever fixedly connected to the outer surface of which is slidably connected to the front of the inner surface of the counterweight seat, a guide rod fixedly connected to the inner surface of the counterweight seat, and the middle of the inner surface of which is slidably connected to the outer surface of the guide rod.

The outer surface of the threaded rod is rotatably connected to the inner surface of the support base.

[0010] As a further description of the above technical solution:

[0011] A power assembly is provided on the left side of the inner surface of the support base. The power assembly includes a motor. The outer surface of the motor is fixedly connected to the left side of the inner surface of the support base. The output shaft of the motor is fixedly connected to a transmission disk A. The outer surface of the transmission disk A is connected to a transmission disk B via a belt drive. The outer surface of the transmission disk B is fixedly connected to the outer surface of the threaded rod.

[0012] As a further description of the above technical solution:

[0013] The outer surface of the support base is fixedly connected to a placement compartment at the front end. A spare counterweight plate is inserted into the inner surface of the placement compartment. A sliding cover is inserted into the top of the inner surface of the placement compartment. A latch is fixedly connected to the bottom of the outer surface of the sliding cover.

[0014] As a further description of the above technical solution:

[0015] A T-shaped plate is fixedly connected to the bottom of the outer surface of the counterweight base, and a T-shaped groove is formed on the inner surface of the support base. The outer surface of the T-shaped plate is slidably connected to the inner surface of the T-shaped groove.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] In this invention, the weight of the counterweight seat can be quickly and conveniently adjusted by inserting or removing counterweight plates on top of the counterweight seat, in conjunction with a snap-fit ​​component. When the inspection robot needs to carry inspection equipment of different weights, the operator can quickly increase or decrease the number of counterweight plates according to actual needs, flexibly changing the weight of the counterweight seat, so that the robot's center of gravity can be precisely adjusted, thereby quickly adapting to the stability requirements of different working conditions and significantly improving work efficiency.

[0024] 2. In this utility model, a storage compartment is provided at the front end of the outer surface of the support base, providing a dedicated storage space for the spare counterweight plate. When it is necessary to increase the weight of the counterweight base, the operator can quickly retrieve the spare counterweight plate from the storage compartment, avoiding the tedious process of searching for and moving the counterweight plate. At the same time, the sliding cover and locking design inside the storage compartment effectively prevents dust and moisture, and prevents the spare counterweight plate from sliding out during robot operation, ensuring not only the performance of the spare counterweight plate, but also the safety and convenience of the retrieval process.

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a support base for an inspection robot, including a support base 1. The support base 1 serves as the basic load-bearing component of the entire device, providing a stable installation platform for the subsequent installation and operation of various components, ensuring the relative position stability of each component during the operation of the inspection robot. A counterweight 6 is slidably connected to the inner surface of the support base 1, allowing the counterweight 6 to be adjusted within the support base 1. By changing the position of the counterweight 6, the center of gravity of the inspection robot can be flexibly adjusted to adapt to different working scenarios and terrain conditions, ensuring the stability of the robot's operation. The top of the outer surface of the counterweight 6 is inserted... A counterweight plate 9 is attached to the top of the counterweight base 6. By increasing or decreasing the number of counterweight plates 9, the weight of the counterweight base 6 can be easily and quickly adjusted, thereby meeting the requirements of the robot's center of gravity and stability under different working conditions and improving the robot's load adaptability. A limit frame 8 is hinged to the rear of the outer surface of the counterweight base 6. The bottom of the inner surface of the limit frame 8 contacts and connects with the top of the outer surface of the counterweight plate 9, so that the limit frame 8 can limit the counterweight plate 9 without affecting the loading and unloading operation of the counterweight plate 9, preventing the counterweight plate 9 from shifting or falling off due to vibration or other factors during robot operation, and ensuring the safety of robot operation.

[0035] Reference Figures 3-4The inner surface of the counterweight base 6 is provided with a snap-fit ​​component 11; this component is used to snap and unlock the limiting frame 8. By precisely controlling the position of the snap-fit ​​block 111, the limiting frame 8 can be effectively fixed or released, thus facilitating the loading and unloading of the counterweight plate 9. The snap-fit ​​component 11 includes a snap-fit ​​block 111, the outer surface of which is slidably connected to the front part of the inner surface of the counterweight base 6, allowing the snap-fit ​​block 111 to move flexibly within the counterweight base 6. Its position can be changed by external force to achieve snap-fit ​​or separation from the limiting frame 8. The outer surface of the snap-fit ​​block 111 is spring-loaded. Spring 113 is elastically connected to the front of the inner surface of counterweight 6. This elastic connection provides the resetting force for the locking block 111. When the locking block 111 is pressed inward by external force and releases its engagement with the limiting frame 8, spring 113 automatically pushes the locking block 111 back to its original position, re-engaging it with the limiting frame 8. This ensures the stability and reliability of the limiting frame 8 when fixing the counterweight plate 9. The top of the outer surface of the locking block 111 engages with the front of the inner surface of the limiting frame 8. This engagement method effectively fixes the limiting frame 8. When the limiting frame 8 is flipped downwards into place... The locking block 111 engages with the front of the limiting frame 8, firmly fixing the limiting frame 8 and ensuring that the counterweight plate 9 is reliably limited, preventing it from loosening. A lever 112 is fixedly connected to the outer surface of the locking block 111, providing the operator with a force application point. By moving the lever 112, the locking block 111 can be easily moved, enabling manual control of the locking block 111. This allows the operator to easily unlock and engage the limiting frame 8. The outer surface of the lever 112 slides against the front of the inner surface of the counterweight seat 6, ensuring that the lever 112 is in contact with the force application point. The mechanism can smoothly drive the locking block 111 to move, while also guiding and limiting the movement of the push block 112, ensuring that the locking block 111 can accurately engage or disengage with the limiting frame 8. The inner surface of the counterweight 6 is fixedly connected to the guide rod 114, and the middle of the inner surface of the locking block 111 penetrates and slides through the outer surface of the guide rod 114, allowing the locking block 111 to slide smoothly on the guide rod 114, further enhancing the stability and guidance of the movement of the locking block 111, and ensuring that the locking assembly 11 maintains good working performance during long-term use.

[0036] Reference Figures 1-3 A threaded sleeve 10 is fixedly connected through the middle of the inner surface of the counterweight seat 6. A threaded rod 7 is threadedly connected through the inner surface of the threaded sleeve 10. The threaded sleeve 10 is fixed in the middle of the inner surface of the counterweight seat 6, providing a foundation for the threaded connection of the threaded rod 7. Through the threaded engagement with the threaded rod 7, the rotational motion of the threaded rod 7 is converted into the linear movement of the counterweight seat 6, realizing precise control of the position of the counterweight seat 6. The outer surface of the threaded rod 7 is rotatably connected to the inner surface of the support base 1, ensuring that the threaded rod 7 can rotate freely within the support base 1, providing the necessary motion conditions for it to drive the threaded sleeve 10 and the counterweight seat 6 to move, and ensuring the smooth operation of the transmission system.

[0037] Reference Figure 6 A power assembly 16 is provided on the left side of the inner surface of the support base 1. The power assembly 16 serves as the power source for moving the counterweight 6, providing power support for the entire center of gravity adjustment system. Through stable and reliable power output, it ensures that the counterweight 6 can be adjusted to the desired position. The power assembly 16 includes a motor 161. The outer surface of the motor 161 is fixedly connected to the left side of the inner surface of the support base 1, providing a stable mounting base for the motor 161 and ensuring that the motor 161 remains stable during operation. The output shaft of the motor 161 is fixedly connected to a transmission disc A162. The outer surface of the transmission disc A162 is connected to a belt 1. The transmission connection 63 includes a transmission disc B164. The transmission disc A162 is fixedly connected to the output shaft of the motor 161, which can effectively transmit the rotational power output by the motor 161. Through cooperation with the belt 163, the power is transmitted to the transmission disc B164, realizing long-distance power transmission and adjustment of the transmission ratio. The outer surface of the transmission disc B164 is fixedly connected to the outer surface of the threaded rod 7, so that the transmission disc B164 can transmit the rotational power transmitted from the belt 163 to the threaded rod 7, so that the threaded rod 7 can rotate according to the driving requirements of the motor 161, thereby driving the counterweight 6 to move and realizing the adjustment of the robot's center of gravity.

[0038] Reference Figures 1-2 , Figure 5 The outer surface of the support base 1 is fixedly connected to the front end of the storage compartment 4, which provides a dedicated storage space for the spare counterweight plate 14. This allows operators to quickly retrieve the spare counterweight plate 14 when the weight of the counterweight seat 6 needs to be increased, thus improving work efficiency. The spare counterweight plate 14 is inserted into the inner surface of the storage compartment 4, allowing it to be placed inside. A sliding cover 5 is inserted into the top of the inner surface of the storage compartment 4, which can protect the spare counterweight plate 14 from dust, moisture, and other external debris, preventing it from entering the storage compartment 4 and affecting its performance and use. It also prevents the spare counterweight plate 14 from sliding out of the storage compartment 4 due to vibration or other factors during robot operation. A latch 15 is fixedly connected to the bottom of the outer surface of the sliding cover 5, which can securely fix the sliding cover 5 to the top of the storage compartment 4, further enhancing the protection of the spare counterweight plate 14 inside the storage compartment 4, preventing the sliding cover 5 from opening accidentally, and ensuring the safety and stability of the spare counterweight plate 14 during storage.

[0039] Reference Figures 3-4 , Figure 6A T-shaped plate 12 is fixedly connected to the bottom of the outer surface of the counterweight seat 6. A T-shaped groove 13 is opened on the inner surface of the support base 1. The outer surface of the T-shaped plate 12 is slidably connected to the inner surface of the T-shaped groove 13. The T-shaped plate 12 is fixed to the bottom of the outer surface of the counterweight seat 6 and cooperates with the T-shaped groove 13 opened on the inner surface of the support base 1 to provide guidance and limit for the sliding of the counterweight seat 6 in the support base 1, prevent the counterweight seat 6 from shaking or deviating during the movement, and ensure that the counterweight seat 6 can slide smoothly along the predetermined direction.

[0040] Reference Figures 2-3 , Figure 5 The top of the outer surface of the counterweight base 6 has a limiting groove to ensure that the counterweight plate 9 can be accurately inserted into the predetermined position on the top of the counterweight base 6, preventing the counterweight plate 9 from being misaligned or tilted during installation, and ensuring the accuracy and stability of the installation of the counterweight plate 9. The top of the outer surface of the sliding cover 5 is slanted. The slanted design can effectively guide rainwater and other liquids from flowing down the surface of the sliding cover 5, preventing liquid from accumulating on the top of the sliding cover 5 and seeping into the placement chamber 4, which would damage the spare counterweight plate 14. The top of the outer surface of the support base 1 is hinged with a top cover 2, which can be easily opened when maintenance or repair of the inside of the support base 1 is required, making it convenient for operators to operate. The front end of the outer surface of the top cover 2 is fixedly connected to a fixing part 3, which is firmly fixed to the support base 1 when the top cover 2 is closed, ensuring that the top cover 2 will not be accidentally opened due to vibration or other factors during robot operation. The top of the outer surface of the top cover 2 is equipped with an inspection device, which enables the inspection robot to achieve the inspection effect.

[0041] Working principle: When the inspection robot travels to the slope, the motor 161 is started, which drives the threaded rod 7 to rotate through the action of two sets of transmission discs and belt 163. When the threaded rod 7 rotates, the counterweight 6 fixed on the outer surface of the threaded sleeve 10 is moved laterally due to the threaded connection with the threaded sleeve 10. When the counterweight 6 moves laterally to the end that first contacts the slope, the center of gravity of the device will change, so that the device will not tilt when traveling on the slope.

[0042] When adding inspection equipment to the inspection robot, the weight of the counterweight 6 needs to be increased according to the weight of the added equipment. This ensures that the anti-tilting effect of the counterweight 6 will not be weakened after the center of gravity changes due to the addition of inspection equipment. When increasing the weight of the counterweight 6 by adding a counterweight plate 9, firstly, simultaneously press the lever 112 on the counterweight 6 inward, causing it to simultaneously drive the two sets of locking blocks 111 inward to release the fixed state between the front end of the limiting frame 8 and the front end of the counterweight 6. Then, flip the limiting frame 8 upward to release the limit on the top of the counterweight plate 9 inserted at the top of the counterweight 6, allowing the counterweight plate 9 to be vertically pulled out or inserted. After releasing the fixation of the sliding cover 5 on the placement compartment 4, slide the sliding cover 5 to the right to open the placement compartment 4. Then, take out a specified number of spare counterweight discs 14 from inside the placement chamber 4 and insert them into the slots set on the top of the counterweight base 6. Then, flip the limiting frame 8 downward so that its front end simultaneously presses the inclined surfaces of the two sets of locking blocks 111, causing the two sets of locking blocks 111 to retract inward so that the locking blocks 111 can be inserted into the front end of the limiting frame 8. When the top of the locking block 111 is fully inserted into the inside of the limiting frame 8, the locking block 111 will expand outward under the elastic force of the spring 113 and lock into the inside of the limiting frame 8, thereby fixing the counterweight disc 9 on the counterweight base 6. Then, re-insert the sliding cover 5 into the top of the placement chamber 4 and fix the sliding cover 5 to the top of the placement chamber 4 through the latch 15, thereby completing the increase of the weight of the counterweight base 6.
