Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection robot technology, specifically an inspection robot with anti-collision function. Background Technology
[0002] To provide effective protection for inspection robots in the event of a collision, a crash beam is typically installed in front of them. This crash beam absorbs the impact kinetic energy by breaking or deforming itself, thereby protecting the robot's core components from damage. Its operating speed is generally less than 30 km / h.
[0003] However, to ensure continuous energy absorption, the strength of the crash beam should not be too high, which makes it more susceptible to damage in a collision. Once the crash beam is damaged, it needs to be replaced, which not only increases maintenance costs but also wastes resources. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention proposes an inspection robot with anti-collision function, which reduces the maintenance cost of the device after an impact.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an inspection robot with anti-collision function, comprising a robot body and an anti-collision beam, wherein a mounting connecting block is fixedly connected to the side wall of the robot body, the anti-collision beam is slidably connected to the mounting connecting block, an energy-absorbing connecting member is detachably connected to the side wall of the anti-collision beam, and a bolt is threadedly connected to one side wall of the energy-absorbing connecting member, one end of the bolt passing through the energy-absorbing connecting member and threadedly connected to the mounting connecting block, and an energy-absorbing component is provided inside the anti-collision beam.
[0006] Preferably, the energy-absorbing component includes a fixing block fixed to the inner wall of the anti-collision beam, and an energy-absorbing counterweight is provided on one side of the fixing block, and a spring is fixedly connected to one side wall of the energy-absorbing counterweight.
[0007] Preferably, a sealing plate is fixedly connected to one end of the anti-collision beam, and a small hole is opened on one side wall of the sealing plate, with a whistle connected to one end of the small hole.
[0008] Preferably, the outer wall of the energy-absorbing counterweight is fixedly fitted with a soft sleeve, and the outer wall of the soft sleeve is interference-fitted with the inner wall of the anti-collision beam.
[0009] Preferably, one end of the mounting connector has a chamfer.
[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention connects the robot body and the anti-collision beam using an energy-absorbing connector. When the anti-collision beam impacts an object, the impact force is transferred to the energy-absorbing connector. If the impact force exceeds the connector's bearing capacity, it breaks. The broken connector absorbs the impact's kinetic energy, thus protecting the robot body. Therefore, after an impact, maintenance only requires replacing the energy-absorbing connector, reducing post-impact repair costs. Furthermore, the energy-absorbing counterweight works in conjunction with a spring. When the anti-collision beam impacts an object, a portion of the impact force causes the counterweight to move. This moving counterweight compresses the spring, converting a portion of the impact force into the counterweight's kinetic energy and the spring's potential energy. This buffers the force on the energy-absorbing connector, reducing its potential damage and further lowering maintenance costs. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Please see Figures 1 to 5An inspection robot with anti-collision function includes a robot body 1 and an anti-collision beam 2. The side wall of the robot body 1 is fixedly connected to a mounting block 3. The anti-collision beam 2 is slidably connected to the mounting block 3. The side wall of the anti-collision beam 2 is detachably connected to an energy-absorbing connector 5. The energy-absorbing connector 5 is made of easily broken and damaged plastic material, while the anti-collision beam 2 is made of metal material, so that the bearing capacity of the anti-collision beam 2 is greater than the bearing capacity of multiple energy-absorbing connectors 5. After the robot body 1 is impacted, the energy-absorbing connector 5 will break and absorb energy first. As long as the impact force is not too large, the anti-collision beam 2 will not be damaged. A bolt 6 is threadedly connected to one side wall of the energy-absorbing connector 5. One end of the bolt 6 passes through the energy-absorbing connector 5 and is threadedly connected to the mounting block 3. An energy-absorbing component is set inside the anti-collision beam 2.
[0015] As can be seen from the above structure: by setting up the energy-absorbing connector 5 to connect the robot body 1 and the anti-collision beam 2, after the anti-collision beam 2 of the robot body 1 hits an object, the impact force is transmitted to the energy-absorbing connector 5. When the impact force exceeds the bearing limit of the energy-absorbing connector 5, the energy-absorbing connector 5 breaks and is damaged. The energy-absorbing connector 5 absorbs the kinetic energy of the impact through its breakage and damage, thereby protecting the robot body 1. In this way, after an impact, the maintenance of this device only requires replacing the energy-absorbing connector 5, thereby reducing the maintenance cost of this device after an impact.
[0016] See Figure 4 and Figure 5 The energy-absorbing component includes a fixed block 7 fixed to the inner wall of the anti-collision beam 2, and an energy-absorbing counterweight 8 is provided on one side of the fixed block 7. A spring 9 is fixedly connected to one side wall of the energy-absorbing counterweight 8. The force of the spring 9 is only enough to press the energy-absorbing counterweight 8 into contact with the fixed block 7. Its strength cannot be too high, so that when the robot body 1 collides with an object at a speed of more than 5 km / h, the reaction force received by the energy-absorbing counterweight 8 can compress the spring 9. By using the energy-absorbing counterweight 8 and the spring 9 together, after the anti-collision beam 2 collides with an object, part of the impact force will cause the energy-absorbing counterweight 8 to move. The moving energy-absorbing counterweight 8 compresses the spring 9, converting part of the impact force into the kinetic energy of the energy-absorbing counterweight 8 and the potential energy of the compressed spring 9, buffering the force borne by the energy-absorbing connector 5, thereby reducing the possibility of damage to the energy-absorbing connector 5 and further reducing the maintenance cost of this device.
[0017] See Figures 1 to 5 One end of the anti-collision beam 2 is fixedly connected to a sealing plate 10, and a small hole 11 is opened on one side wall of the sealing plate 10. One end of the small hole 11 is connected to a whistle 4. By setting the sealing plate 10, the end of the anti-collision beam 2 can be sealed. When the energy-absorbing counterweight 8 moves, the air in the anti-collision beam 2 can be compressed, so that the air is discharged through the small hole 11 and the whistle 4, causing the whistle 4 to make a whistle sound to remind the personnel on site.
[0018] See Figure 4 The outer wall of the energy-absorbing counterweight 8 is fixedly fitted with a soft sleeve, and the outer wall of the soft sleeve is interference-fitted with the inner wall of the anti-collision beam 2. By setting the soft sleeve, the sealing performance of the energy-absorbing counterweight 8 can be increased, ensuring that the energy-absorbing counterweight 8 can force the air out of the anti-collision beam 2.
[0019] See Figure 2 and Figure 3 One end of the mounting connecting block 3 is chamfered; by setting the chamfer, it is easier to insert the anti-collision beam 2 when installing it, and the mounting connecting block 3 can support and limit the anti-collision beam 2 during installation, so that no one needs to hold the anti-collision beam 2, which facilitates the installation of the anti-collision beam 2.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
