Description

Technical Field

[0001] The present invention belongs to the technical field of engineering robots, and particularly relates to a robot chassis with an adjustable integrated hydraulic system and an engineering robot. Background Art

[0002] Engineering robots are widely used in construction sites. They can simulate construction actions, replace manual labor to complete intelligent operations, save labor intensity, and have high efficiency and high precision. Commonly used ones include transportation robots, loading and unloading robots, demolition robots, etc.

[0003] An engineering robot generally includes a body, a robotic arm, as well as a chassis and crawlers installed at the bottom of the body. The crawlers are connected to the chassis and are controlled and driven by a hydraulic system. In the existing related technologies, when an engineering robot works at a construction site, if it encounters uneven terrain or terrain with potholes, it will affect the normal walking of the crawlers of the engineering robot chassis. Therefore, it is necessary to adjust the distance between the two crawlers of the robot to avoid uneven terrain or terrain with potholes, so that the engineering robot can adapt to different working environments.

[0004] Moreover, when an engineering robot constructs on terrain with a certain slope, the hydraulic oil inside the hydraulic system will tilt towards the lower side, causing the outlet pipe to suck in air instead of oil during the process of adjusting the crawlers, resulting in air intrusion into the hydraulic system to produce adverse effects and causing faults in the hydraulic system.

[0046] Referring to Figures 1 - 8 , one embodiment of the present invention provides an adjustable robot chassis for an integrated hydraulic system, including:

[0047] An installation base 100, the installation base 100 is provided with a hydraulic system 200 and a pushing mechanism 300;

[0048] A traveling mechanism 400, the traveling mechanism 400 is arranged on the left and right sides of the installation base 100, and the traveling mechanism 400 is respectively connected to the hydraulic system 200 and the pushing mechanism 300 on the installation base 100;

[0049] Wherein, the hydraulic system 200 includes a hydraulic cylinder 210 and a hydraulic oil tank 220, the hydraulic cylinder 210 is connected to the traveling mechanism 400 and is used to push the traveling mechanism 400 to change the distance between the two traveling mechanisms 400;

[0050] The hydraulic oil tank 220 is provided with an oil outlet pipe 230 and an oil return pipe 240, and the oil outlet pipe 230 is located at the middle position of the hydraulic oil tank 220;

[0051] The oil outlet pipe 230 is provided with a floating device 500 for controlling the opening and closing of the oil outlet pipe 230.

[0052] In this embodiment, referring to Figure 1, Specifically, the mounting base 100 is provided with a hydraulic system 200, a pushing mechanism 300, and traveling mechanisms 400 are arranged on both the left and right sides of the mounting base 100. The hydraulic system 200 includes a hydraulic cylinder 210 and a hydraulic oil tank 220. The hydraulic oil tank 220 has an oil outlet pipe 230 and an oil return pipe 240. The hydraulic cylinder 210 is fixedly installed in the mounting base 100 by bolts, and the hydraulic cylinder 210 is connected to the traveling mechanism 400. The traveling mechanism 400 is pushed by the hydraulic cylinder 210 to change the distance between the traveling mechanisms 400 on both sides of the mounting base 100, so that the traveling mechanism 400 can obtain an appropriate width according to different terrains; the hydraulic oil tank 220 is used to load hydraulic oil, and the hydraulic oil tank 220 is fixedly installed above the mounting base 100 by bolts. The oil outlet pipe 230 and the oil return pipe 240 of the hydraulic oil tank 220 are communicated with the hydraulic cylinder 210. The oil outlet pipe 230 provides hydraulic oil for the hydraulic cylinder 210, causing the hydraulic cylinder 210 to generate pressure, making the hydraulic cylinder 210 perform a linear motion, driving the traveling mechanism 400 to change the distance. After the movement of the hydraulic cylinder 210 is completed, the excess hydraulic oil is returned to the hydraulic oil tank 220 through the oil return pipe 240 to complete a complete working cycle. As Figure 3 shown, the oil outlet pipe 230 of the hydraulic oil tank 220 is located at the middle position of the hydraulic oil tank 220, and floating devices 500 are arranged at both ends of the oil outlet pipe 230 for controlling the opening and closing of the oil outlet pipe 230, so that the oil outlet pipe 230 in the hydraulic oil tank 220 can normally suck hydraulic oil without being evacuated, ensuring the stability of the equipment and also extending the service life of the hydraulic system 200; as Figure 3 shown, when the chassis is working on a horizontal road, the floating devices 500 at both ends of the oil outlet pipe 230 are in an open and closed state, and hydraulic oil can enter from both ends; Figure 7 、 Figure 8 shown, when the chassis is working on an uphill or downhill road, the hydraulic oil will tilt to one side, causing one end of the oil outlet pipe 230 to be in an open and closed state and the other end to be in a closed state, ensuring that one side of the oil outlet pipe 230 is always in an open and closed state; in this embodiment, no matter what slope the chassis is working on, it can normally suck hydraulic oil without being evacuated, ensuring the stable operation of the robot and improving the overall uphill / downhill ability of the robot.

[0053] In one embodiment, the oil outlet pipe 230 is a composite oil outlet pipe 230, including a first pipe 231 and a second pipe 232, and the first pipe 231 is connected to the second pipe 232 through a tee pipe 233. Fixed rods 234 are arranged at both ends of the second pipe 232; [[ID=I2]]

[0054] The floating device 500 is arranged on the fixed rods 234 at both ends of the second pipe 232, and the floating device 500 is rotatably connected to the fixed rods 234.

[0055] In this embodiment, referring to Figure 2 , specifically, the oil outlet pipe 230 is a composite oil outlet pipe 230, which is composed of a first pipe 231, a second pipe 232 and a tee pipe 233. The first pipe 231 and the second pipe 232 are connected through the tee pipe 233; fixing rods 234 are arranged at both ends of the second pipe 232, and a floating device 500 is rotatably arranged on the fixing rods 234 to control the opening and closing of the second pipe 232 through the floating device 500; when the chassis is in an inclined state, the floating device 500 of the second pipe 232 rotates on the fixing rods 234 to open one end and close the other end.

[0056] In one of the embodiments, the floating device 500 includes:

[0057] A first connecting rod 510, the first connecting rod 510 is arranged on the fixing rod 234, and one end of the first connecting rod 510 is rotatably connected to the fixing rod 234;

[0058] A floating ball 520, the floating ball 520 is arranged at the other end of the first connecting rod 510, and the floating ball 520 is fixedly connected to the first connecting rod 510;

[0059] A second connecting rod 530, the second connecting rod 530 is arranged on the fixing rod 234, and one end of the second connecting rod 530 is rotatably connected to the fixing rod 234;

[0060] A cover plate 540, the cover plate 540 is arranged at the other end of the second connecting rod 530, and the cover plate 540 is fixedly connected to the second connecting rod 530.

[0061] In this embodiment, referring to Figures 4 - 6 , the floating device 500 includes a first connecting rod 510, a floating ball 520, a second connecting rod 530 and a cover plate 540; as Figure 3 shown, when the chassis is working on a horizontal road, the hydraulic oil in the hydraulic oil tank 220 is in a normal state, the floating ball 520 floats in the hydraulic oil, and through the buoyancy of the floating ball 520, the first connecting rod 510 rotates upward. The first connecting rod 510 drives the second connecting rod 530 to rotate accordingly through the hinge connecting piece 550, so that the cover plate 540 opens upward, and both ends of the second pipe 232 are in an open state; Figure 7 , Figure 8As shown, when the chassis is working on an uphill or downhill road, the hydraulic oil in the hydraulic oil tank 220 will tilt to one side. The float ball 520 on the tilted side of the hydraulic oil floats in the hydraulic oil. Through the buoyancy of the float ball 520, the first connecting rod 510 rotates upward. The first connecting rod 510 drives the second connecting rod 530 to rotate accordingly through the hinge connecting piece 550, so that the cover plate 540 opens upward, and the port on this side of the second pipeline 232 is in an open or closed state, as Figure 5 shown; on the other hand, the float ball 520 on the side without hydraulic oil sinks downward under the action of gravity. The float ball 520 drives the first connecting rod 510 to rotate downward. The first connecting rod 510 drives the second connecting rod 530 to rotate accordingly through the hinge connecting piece 550, so that the cover plate 540 at one end of the second connecting rod 530 is pressed downward, as Figure 6 shown. At the same time, due to the action of the hinge connecting piece 550, the cover plate 540 presses the second pipeline 232, so that the port on this side of the second pipeline 232 is tightly closed, preventing air from entering from this side when extracting hydraulic oil, which may cause air to invade the hydraulic system 200 and produce adverse effects, resulting in failures of the hydraulic system 200.

[0062] In one embodiment, hinge connecting pieces 550 are provided between the first connecting rod 510, the second connecting rod 530 and the fixed rod 234. The hinge connecting pieces 550 are respectively connected to the first connecting rod 510, the second connecting rod 530 and the fixed rod 234. The first connecting rod 510 drives the second connecting rod 530 through the hinge connecting piece 550.

[0063] In this embodiment, the first connecting rod 510, the second connecting rod 530 and the fixed rod 234 are connected through the hinge connecting piece 550. At the same time, due to the action of the hinge connecting piece 550, the cover plate 540 can press the second pipeline 232, so that the port of the second pipeline 232 is tightly closed, preventing air from entering from this side when extracting hydraulic oil, which may cause air to invade the hydraulic system 200 and produce adverse effects, resulting in failures of the hydraulic system 200.

[0064] As needed, the first connecting rod 510 and the second connecting rod 530 can be connected by an elastic connecting member (not shown in the figure); one end of the first connecting rod 510 is rotatably connected to one end of the fixed rod 530, and one end of the second connecting rod 530 is also rotatably connected to one end of the fixed rod 234, and the second connecting rod 530 is located between the fixed rod 234 and the first connecting rod 510; when the chassis works on an uphill or downhill road, the hydraulic oil in the hydraulic oil tank 220 will tilt to one side, and the float ball 520 on the tilted side of the hydraulic oil floats in the hydraulic oil. Through the buoyancy of the float ball 520, the first connecting rod 510 is rotated upward, and the first connecting rod 510 drives the second connecting rod 530 to rotate upward through the elastic connecting member, so that the cover plate 540 is opened upward, and the port of the second pipeline 232 on this side is in an open and closed state to maintain the flow of hydraulic oil; in addition, the float ball 520 on the side without hydraulic oil sinks downward under the action of gravity, drives the first connecting rod 510 to rotate downward through the float ball 520, and the first connecting rod 510 drives the second connecting rod 530 to rotate downward through the elastic connecting member, so that the cover plate 540 abuts against the second pipeline 232, and the port of the second pipeline 232 on this side is in a closed state, avoiding air from entering from this side when extracting hydraulic oil, resulting in air intrusion into the hydraulic system 200 to produce adverse effects and causing faults in the hydraulic system 200.

[0065] In this embodiment, due to the elastic force of the elastic connecting member, when the float ball 520 sinks downward under the action of gravity, the float ball 520 drives the first connecting rod 510. Under the elastic force of the elastic connecting member, the first connecting rod 510 presses downward, providing pressure to the second connecting rod 530, so that the cover plate 540 at one end of the second connecting rod 530 presses tightly against the port of the second pipeline 232 on this side.

[0066] In one of the embodiments, an installation groove 110 is provided in the middle of the installation base 100, the hydraulic cylinder 210 is disposed in the installation groove 110, and the push rod 211 of the hydraulic cylinder 210 is connected to the traveling mechanism 400 for pushing the traveling mechanism 400 to change the distance between the two traveling mechanisms 400.

The end of the pushing rod 211 of the hydraulic cylinder 210 is fixedly connected to the traveling mechanism 400, and is used to drive the traveling mechanism 400 to adjust the distance when making a linear motion. One end of the pushing mechanism 300 slides in the sliding groove 120, and the other end is connected to the traveling mechanism 400, and is used to support the traveling mechanism 400 to improve the stability of the traveling mechanism 400 when adjusting the distance.

[0069] In one embodiment, two hydraulic cylinders 210 are symmetrically arranged left and right in the installation groove 110, and the directions of the pushing rods 211 of the two hydraulic cylinders 210 are opposite, and are respectively used to be connected to the traveling mechanism 400.

[0070] In this embodiment, specifically, two hydraulic cylinders 210 are provided in the installation groove 110, and the directions of the pushing rods 211 of the two hydraulic cylinders 210 are opposite, and are used to connect the traveling mechanisms 400 on both sides of the installation base 100. When adjusting the distance, the two hydraulic cylinders 210 adjust the traveling mechanism 400 at the same time to improve the stability of the traveling mechanism 400 during adjustment. According to needs, more than two hydraulic cylinders 210 can be provided in the installation groove 110, and are arranged in integer multiples of two, depending on the actual use requirements.
