Description

Technical Field

[0001] This utility model relates to the field of bomb disposal robot technology, specifically a bomb disposal robot transfer structure. Background Technology

[0002] Bomb disposal robots are specialized equipment used by bomb disposal personnel to handle or destroy suspected explosive items, avoiding unnecessary casualties. They can be used in various complex terrains for bomb disposal and are mainly used to replace bomb disposal personnel in carrying and transferring suspected explosive items and other hazardous materials. Due to their high technological content, bomb disposal robots are often quite expensive.

[0003] A published patent document with announcement number CN219132296U discloses a bomb disposal robot. This published patent document describes a second rotating shaft driven by a motor-driven connecting shaft, which rotates due to the meshing of two bevel gears. The cutting blades on the second rotating shaft clear vegetation from the bomb disposal area. Simultaneously, the first rotating shaft rotates with the second rotating shaft under the transmission component. The long rod on the first rotating shaft breaks up the soil on the bomb disposal area and detonates unexploded ordnance in the shallow layer of the ground. As the tracked vehicle moves forward, lime in the material box flows to the ground through the discharge pipe, which facilitates the demarcation of the bomb disposal area and makes it easier for staff to inspect. However, in the aforementioned published patent document, the bomb disposal robot vehicle body requires additional space for conversion or turning, making it unsuitable for conversion or turning in confined spaces and resulting in poor flexibility of use. Utility Model Content

[0004] The purpose of this invention is to provide a transfer structure for a bomb disposal robot, which solves the problems mentioned in the background art.

[0005] This application provides a transport structure for an explosive ordnance disposal (BOD) robot, including a BOD robot frame. The BOD robot frame has an internal steering assembly, which includes a support plate and four electric cylinders. All four electric cylinders are fixedly mounted on the top inner wall of the BOD robot frame, and their output ends are fixedly mounted to the top of the support plate. A servo motor is fixedly mounted in the middle of the top of the support plate, and four conversion shafts are equidistantly arranged below the support plate. The output end of the servo motor passes through the support plate and is fixedly mounted with a driving bevel gear. A roller is fixedly mounted at one end of each conversion shaft, and a driven bevel gear is fixedly mounted at the other end. The driving bevel gear meshes with all four driven bevel gears.

[0006] By adopting the above technical solution, the electric cylinder drives the support plate to move downward, so that the rollers contact the ground. The servo motor drives the active bevel gear to rotate, and the active bevel gear drives the four conversion shafts to rotate through the four driven bevel gears, which in turn drives the four rollers to rotate synchronously, thereby driving the bomb disposal robot frame to rotate in place to turn or turn around.

[0007] Optionally, the front and rear sides of the bomb disposal robot frame are symmetrically equipped with wide track wheels and narrow track wheels. A rotating shaft is connected through the middle of the wide track wheel and is rotatably mounted to the bomb disposal robot frame. A rotating shaft is connected through the middle of the narrow track wheel and is rotatably mounted to the bomb disposal robot frame. A transverse track is provided between the wide track wheel and the narrow track wheel.

[0008] By adopting the above technical solution, the transverse track between the wide track wheel and the narrow track wheel ensures the stability of the bomb disposal robot's chassis during horizontal movement.

[0009] Optionally, support rods are fixedly connected to the front and rear of one side of the bomb disposal robot frame. Small track wheels are provided on the opposite sides of the two support rods. A rotating shaft three is connected through the middle of the small track wheel and is interference-fitted. The rotating shaft three is rotatably installed with the support rod. An inclined track is provided between the wide track wheel and the small track wheel.

[0010] By adopting the above technical solution, the inclined track between the wide track wheel and the small track wheel enables the bomb disposal robot frame to climb.

[0011] Optionally, a dual-head motor is fixedly installed inside the bomb disposal robot frame, and the output ends of the dual-head motor on the front and rear sides are respectively fixedly installed with the two rotating shafts.

[0012] By adopting the above technical solution, the dual-head motor drives the two rotating shafts and the wide track wheel to rotate, thereby driving the horizontal and oblique tracks to move, providing kinetic energy for the movement of the bomb disposal robot's chassis.

[0013] Optionally, two kits are sleeved on and rotatably connected to the conversion shaft, with the top of the kits fixedly installed to the bottom of the support plate.

[0014] By adopting the above technical solution, the kit ensures the stability of the conversion shaft rotation.

[0015] Optionally, a mounting base is fixedly connected to the top of the bomb disposal robot frame, and the mounting base has several mounting holes.

[0016] By adopting the above technical solution, the mounting holes on the mounting base facilitate the installation of the explosive ordnance disposal robot's robotic arm.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses a steering assembly consisting of a support plate, an electric cylinder, a servo motor, an active bevel gear, a driven bevel gear, a conversion shaft, a kit, and rollers to drive the bomb disposal robot frame to rotate in place. It is suitable for turning or turning around in confined spaces and is quite flexible in use.

[0019] 2. The technical solution of this application uses a dual-head motor to drive two rotating shafts and wide track wheels to rotate, thereby driving the horizontal track and the diagonal track to move, so as to provide kinetic energy for the movement of the bomb disposal robot frame. The horizontal track can ensure the stability of the horizontal movement of the bomb disposal robot frame, and the diagonal track enables the bomb disposal robot frame to have climbing function.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-4This utility model provides a transport structure for an explosive ordnance disposal robot, including an explosive ordnance disposal robot frame 1. The frame 1 has a steering assembly 2 inside. The steering assembly 2 includes a support plate 21 and four electric cylinders 22. The four electric cylinders 22 are all fixedly installed on the top inner wall of the frame 1. The output end of the electric cylinders 22 is fixedly installed on the top of the support plate 21. A servo motor 23 is fixedly installed in the middle of the top of the support plate 21. Four conversion shafts 25 are equidistantly arranged below the support plate 21. The output end of the servo motor 23 passes through the support plate 21 and is fixedly installed with a drive bevel gear 26. A roller 24 is fixedly installed at one end of the conversion shaft 25, and a driven bevel gear 27 is fixedly installed at the other end of the conversion shaft 25. The drive bevel gear 26 is meshed with the four driven bevel gears 27.

[0028] In this technical solution, the electric cylinder 22 drives the support plate 21 to move downward, so that the roller 24 contacts the ground until the bomb disposal robot frame 1 is suspended in the air. The servo motor 23 then drives the active bevel gear 26 to rotate. The active bevel gear 26 drives the four conversion shafts 25 to rotate through four meshing driven bevel gears 27, which in turn drives the four rollers 24 to rotate synchronously, thereby driving the bomb disposal robot frame 1 to rotate in place. This is suitable for turning or turning around in place in confined spaces.

[0029] In some technical solutions, such as Figure 1-2 As shown, the front and rear sides of the bomb disposal robot frame 1 are symmetrically equipped with wide track wheels 3 and narrow track wheels 4. A pivot 6 is inserted through the middle of the wide track wheel 3 and is connected with an interference fit. The pivot 6 is rotatably mounted to the bomb disposal robot frame 1. A pivot 7 is inserted through the middle of the narrow track wheel 4 and is connected with an interference fit. The pivot 7 is rotatably mounted to the bomb disposal robot frame 1. A cross track 9 is provided between the wide track wheel 3 and the narrow track wheel 4.

[0030] During use, the horizontal stability of the bomb disposal robot chassis 1 can be ensured by the transverse track 9 between the wide track wheel 3 and the narrow track wheel 4.

[0031] In some technical solutions, such as Figure 1-2 As shown, support rods 13 are fixedly connected to the front and rear of one side of the bomb disposal robot frame 1. Small track wheels 5 are provided on the opposite sides of the two support rods 13. A rotating shaft 3 8 is connected through the middle of the small track wheel 5 with an interference fit. The rotating shaft 3 8 is rotatably installed with the support rod 13. An inclined track 10 is provided between the wide track wheel 3 and the small track wheel 5.

[0032] In use, the oblique track 10 between the wide track wheel 3 and the small track wheel 5 enables the bomb disposal robot frame 1 to climb.

[0033] In some technical solutions, such as Figure 1-2As shown, a dual-head motor 14 is fixedly installed inside the bomb disposal robot frame 1. The output ends of the dual-head motor 14 on the front and rear sides are fixedly installed with two rotating shafts 6 respectively.

[0034] In use, the dual-head motor 14 drives the two rotating shafts 6 and the wide track wheel 3 to rotate, thereby driving the horizontal track 9 and the diagonal track 10 to move, so as to provide kinetic energy for the movement of the bomb disposal robot frame 1.

[0035] In some technical solutions, such as Figure 4 As shown, two kits 28 are sleeved on and rotatably connected to the conversion shaft 25, and the top of the kits 28 is fixedly installed to the bottom of the support plate 21.

[0036] When in use, the stability of the rotation of the conversion shaft 25 is ensured by the kit 28.

[0037] In some technical solutions, such as Figure 1 As shown, the top of the bomb disposal robot frame 1 is fixedly connected to a mounting base 11, and the mounting base 11 has several mounting holes 12.

[0038] When in use, the mechanical arm of the bomb disposal robot can be easily installed through the mounting holes 12 on the mounting base 11.

[0039] Working principle: During use, the dual-head motor 14 drives the two rotating shafts 6 and the wide track wheel 3 to rotate, thereby driving the horizontal track 9 and the diagonal track 10 to move, so as to provide kinetic energy for the movement of the bomb disposal robot frame 1. The horizontal track 9 can ensure the stability of the horizontal movement of the bomb disposal robot frame 1, and the diagonal track 10 enables the bomb disposal robot frame 1 to climb. When the bomb disposal robot frame 1 travels to a narrow space, the electric cylinder 22 drives the support plate 21 to move downward, so that the roller 24 contacts the ground until the bomb disposal robot frame 1 is suspended in the air. The servo motor 23 then drives the active bevel gear 26 to rotate. The active bevel gear 26 drives the four conversion shafts 25 to rotate through the four meshing driven bevel gears 27, which can drive the four rollers 24 to rotate synchronously, thereby driving the bomb disposal robot frame 1 to turn or turn around in place.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
