Description

Technical Field

[0001] This utility model relates to the field of drainage equipment, and more specifically, it relates to a municipal drainage robot. Background Technology

[0002] A robot is an intelligent machine capable of semi-autonomous or fully autonomous operation. Robots can perform tasks such as work or movement through programming and automatic control. Among them, there are robots used for flood drainage, which are used for disaster relief and rescue after floods.

[0003] Chinese Patent CN217379195U discloses a hydraulic tracked drainage robot, including a tracked walking mechanism. Two tracked walking mechanisms are arranged in parallel. A mounting carriage is slidably connected to the inner side of a mounting mechanism. A drainage mechanism is fixedly installed inside the mounting carriage. Two first hydraulic cylinders are rotatably mounted on both sides of one side of the mounting mechanism. The output ends of the two first hydraulic cylinders are respectively connected to the two sides of the mounting carriage. Two second hydraulic cylinders are rotatably mounted on the upper surface of a connecting plate. The output ends of the two second hydraulic cylinders are respectively rotatably connected to the two sides of the mounting mechanism. This utility model utilizes the coordinated arrangement of the first and second hydraulic cylinders. Through the extension and retraction of the first and second hydraulic cylinders, the angle and height of the drainage mechanism can be adjusted. This function enables it to complete water pumping operations under various working conditions, making the adjustment of the height and angle of the drainage mechanism more convenient and flexible.

[0004] However, drainage robots are often large and heavy, and transporting them using ordinary flatbed trucks requires the use of hoisting or forklift equipment, which is quite troublesome.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a municipal drainage robot.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal drainage robot, including a body, on which a drive track is installed, and several lifting support legs are provided on the edge of the body. The lifting support legs adopt a hydraulic lifting structure, and a support plate is provided at the bottom end of the lifting support legs. The support plate and the bottom end of the lifting support legs are connected by a universal joint structure. The universal joint structure includes a ball head fixedly connected to the bottom end of the lifting support leg, a base fixedly connected to the top surface of the support plate, and two arc-shaped locking blocks detachably connected to the top surface of the base. A hemispherical groove for accommodating the lower half of the ball head is provided in the center of the top surface of the base. A locking groove is provided on the bottom surface of the arc-shaped locking blocks. The hemispherical groove and the locking grooves on the two arc-shaped locking blocks communicate to form a steering cavity for accommodating the movement of the ball head.

[0008] The present invention is further configured such that: the inner edges of the two arc-shaped blocks are provided with the same upper sealing ring, the inner edge of the sealing ring abuts against the ball head, the top surface of the base is provided with a lower sealing ring, the hemispherical groove is located inside the lower sealing ring, and the lower sealing ring abuts against the bottom surface of the two arc-shaped blocks.

[0009] The present invention is further configured such that: an arc-shaped groove is provided on the inner wall of the slot, and the upper sealing ring is inserted into the arc-shaped groove.

[0010] The present invention is further configured such that: the top surface of the base is provided with an annular groove, and the lower sealing ring is inserted into the annular groove.

[0011] The present invention is further configured such that the arc-shaped card block and the base are fixed by bolts.

[0012] In summary, this utility model has the following beneficial effects: During robot loading, the robot body is supported by lifting support legs on its edge, allowing the flatbed truck body (loading platform) to be inserted under the robot body. The flatbed truck only needs to tilt the carrying platform under the robot body without colliding with the robot's front and rear support legs. The optimal angle is to reverse perpendicular to the tracks. Retracting the lifting support legs lowers the robot body, placing it on the flatbed truck for easy loading of the drainage robot. After retracting the support legs, the robot rotates in place, ensuring that the entire robot, including the support legs, is on the carrying platform. The tracks can complete the rotation in place. This tracked drainage robot achieves its steering function through the speed difference between the two tracks. Specifically, when the inner and outer tracks rotate in opposite directions, the vehicle can complete a turning motion in place. The inner and outer tracks rotating in opposite directions at the same speed also keeps the center of gravity of the drainage robot almost unchanged during the turning process, allowing it to stably adjust its posture on the flatbed. Wooden boards can be placed on the flatbed to avoid wear caused by friction between the tracks and the flatbed's load-bearing surface. When transported to the destination, the drainage robot is rotated using the characteristics of the tracks until the lifting support legs are exposed on both sides of the flatbed. By extending the lifting support legs, the lifting support legs can be supported on the ground. Then, as the lifting support legs extend further, they can support the body, allowing the bottom of the body to separate from the flatbed truck. The flatbed truck can then be driven away to unload the drainage robot in place. Thus, the drainage robot can be transported without special vehicles, only with flatbed trucks of 4.2 meters or more, without any hoisting or forklift equipment. The robot's built-in lifting function can complete the loading and unloading. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0021] A municipal drainage robot, such as Figure 1 and Figure 6 As shown, the robot includes a body 1 equipped with drive tracks. These tracks propel the body 1, allowing it to adapt to various terrains and preventing it from easily sinking into the ground. Four lifting support legs 2 are mounted on the edges of the body 1. During loading, these legs support the body 1, allowing the flatbed truck (loading platform) to be inserted underneath. The flatbed truck only needs to tilt its platform under the body 1 without colliding with the robot's front and rear lifting support legs 2. The optimal angle is to reverse perpendicular to the tracks, retracting the lifting support legs 2 to lower the body 1 onto the flatbed truck for easy loading. After retracting the lifting support legs 2, the robot rotates in place, ensuring the entire robot, including the support legs, is on the loading platform. This tracked drainage robot achieves its steering function through the speed difference between its two tracks. Specifically, when the inner and outer tracks rotate in opposite directions, the vehicle can complete a turning motion in place. The fact that the inner and outer tracks rotate at the same speed in opposite directions also keeps the center of gravity of the drainage robot almost unchanged during turning, allowing it to stably adjust its posture on the flatbed. Wooden planks can be placed on the flatbed to prevent wear caused by friction between the tracks and the flatbed's load-bearing surface. Upon arrival at the destination, the drainage robot is rotated using the characteristics of the tracks until the lifting support legs 2 are exposed on both sides of the flatbed. By extending the lifting support legs 2, they can be supported on the ground. As the lifting support leg 2 extends further, it can support the body 1, allowing the bottom of the body 1 to separate from the flatbed truck. Then, the flatbed truck can be driven away to unload the drainage robot on the spot. This means that the drainage robot can be transported without special vehicles, only with flatbed trucks of 4.2 meters or more. No hoisting or forklift equipment is needed. The robot's built-in lifting function can complete loading and unloading. When the drainage robot is working, the lifting support leg 2 can be raised to increase the height of the body 1, giving the body 1 a deeper wading depth and improving the functionality of the product.

[0022] Furthermore, such as Figure 1As shown, the lifting support leg 2 adopts a hydraulic lifting structure. The hydraulic lifting structure is a technology well known to those skilled in the art, so it will not be described in detail here. The lifting support leg 2 of the hydraulic lifting structure can lift the body 1 smoothly. During the lifting process, the hydraulic lifting structure will drive the oil pump through the electric motor to deliver oil to the hydraulic cylinder, thereby realizing the lifting operation of the lifting support leg 2. Due to the good balance of the hydraulic lifting structure, there will be no shaking or trembling during lifting, making the operation more stable and reliable. Moreover, the slow lifting and lowering through hydraulic oil results in less noise compared to other types of lifting devices.

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, the bottom end of the lifting support leg 2 is provided with a support plate 3. The support plate 3 and the bottom end of the lifting support leg 2 are connected by a universal joint structure. The support plate 3 can increase the contact area between the lifting support leg 2 and the ground, thereby reducing the pressure and making it less likely for the lifting support leg 2 to sink into the ground. It also improves the stability of the body 1 when it is raised and lowered. Since the ground is often not perfectly flat, the support plate 3 connected by the universal joint structure can move freely to a certain extent and can adapt to uneven ground.

[0024] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the universal joint structure includes a ball head 4 welded to the bottom of the lifting support leg 2, a base 5 welded to the top surface of the support plate 3, and two detachable arc-shaped locking blocks 6 connected to the top surface of the base 5. The center of the top surface of the base 5 is provided with a hemispherical groove 7 to accommodate the lower half of the ball head 4. The bottom surface of the arc-shaped locking blocks 6 is provided with a locking groove 8. The hemispherical groove 7 and the locking groove 8 on the two arc-shaped locking blocks 6 are connected to form a steering cavity to accommodate the movement of the ball head 4. When the support plate 3 is fixed to the lifting support leg 2, the ball head 4 is inserted into the hemispherical groove 7. Then, the two arc-shaped locking blocks 6 are installed from the upper half of the ball head 4 onto the base 5, so that the ball is inserted into the locking groove 8. Then, the arc-shaped locking plate and the base 5 are fixed. The arc-shaped locking blocks 6 and the base 5 are fixed with bolts. This fixing method is relatively firm and easy to disassemble and assemble. The steering cavity formed by the hemispherical groove 7 and the locking groove 8 can accommodate the movement of the ball head 4, thereby facilitating the support plate 3 to fit on uneven road surfaces.

[0025] like Figure 3 , Figure 4 and Figure 5As shown, the inner edges of the two arc-shaped blocks 6 are provided with the same upper sealing ring 9, and the inner edge of the sealing ring abuts against the ball head 4. The top surface of the base 5 is provided with a lower sealing ring 10, and the hemispherical groove 7 is located inside the lower sealing ring 10. The lower sealing ring 10 abuts against the bottom surface of the two arc-shaped blocks 6. Since the working environment of the drainage robot is relatively complex, it often needs to wade through water or operate on muddy roads. Mud and sand can easily fall into the universal joint structure. The setting of the upper sealing ring 9 and the lower sealing ring 10 can form a sealing structure between the ball head 4 and the two arc-shaped blocks 6, and between the two arc-shaped blocks 6 and the base 5, so that the steering cavity is relatively clean and there is no gap between the ball and the inner wall of the steering cavity. It is easy for mud and sand to fall in, thus ensuring smooth movement of the ball and preventing wear and tear, thereby increasing its service life. Specifically, the inner wall of the slot 8 is provided with an arc-shaped groove 11, into which the upper sealing ring 9 is inserted. The top surface of the base 5 is provided with an annular groove 12, into which the lower sealing ring 10 is inserted. The arc-shaped groove 11 and the annular groove 12 respectively fix the upper sealing ring 9 and the lower sealing ring 10, facilitating their installation. The upper sealing ring 9 and the lower sealing ring 10 are made of rubber, which provides a good sealing effect and, through their deformation, does not interfere with the normal movement of the ball.

[0026] like Figure 4 As shown, several reinforcing plates 13 are welded to the outer wall of the base 5, and the reinforcing plates 13 are welded to the support plate 3. The reinforcing plates 13 can improve the connection strength between the base 5 and the support plate 3, so that the support plate 3 and the lifting support leg 2 can support the body 1 well.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
