DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-2The embodiment of the present invention provides a chassis, including a traveling device. In addition, the chassis also includes a body stabilizing mechanism and a lifting frame 3. The body stabilizing mechanism includes a frame 20, and the frame 20 is provided with a driving component for driving the lifting frame 3 to vertically lift and an adjusting component for adjusting the height of the moving wheels 10 of the traveling device. In the present embodiment, the frame 20 and the lifting frame 3 can both be preferably square frames, which can provide stable support, wherein the frame 20 supports the lifting frame 3, and the lifting frame 3 supports the material-retrieving device. The traveling device preferably has four moving wheels 10, and the four moving wheels 10 are respectively arranged at the four vertical prisms of the square frame 20, and more preferably, each vertical prism is provided with an adjusting component for adjusting the height of the four moving wheels 10, so that it can adapt to traveling in areas with many potholes. The lifting frame 3 is connected to the frame 20 below it through a driving assembly. The operator can control the vertical lifting of the lifting frame 3 by controlling the driving assembly, and then control the height of the material-retrieving device arranged on the lifting frame 3, so that it can continue to operate while moving, which can improve the efficiency and accuracy of material retrieving.

[0029] For details on the above drive components, see Figure 1-2 The driving assembly includes a first guide rail 42 and a third driving member 40. The first guide rail 42 and the third driving member 40 are both mounted on the frame 20. The first guide rail 42 and the third driving member 40 are both vertically arranged, and the pushing part of the third driving member 40 suspends the lifting frame 3. The lifting frame 3 is slidably arranged on the first guide rail 42. In this embodiment, the third driving member 40 adopts a hydraulic cylinder, and its pushing part is a piston. The lifting frame 3 is driven to rise and fall by hydraulic driving force. The hydraulic cylinder is a prior art, and its specific working principle is not described in detail here, or a motor screw is adopted. Specifically, in order to avoid affecting the space under the frame 20, the third driving member 40 is inverted, that is, the base of the third driving member 40 is installed on a rod body at a higher position of the frame 20, and then the lifting frame 3 is suspended by the piston of the third driving member 40, and then the lifting frame 3 is stably slid by the first guide rail 42. Of course, in addition to using hydraulic cylinders for driving, screw drives, chains, belts, gears or pneumatic drives can also be used. These are all feasible existing solutions, and their specific structures and working principles will not be described in detail here.

[0030] To refine the above adjustment components, see Figure 1-2The adjustment assembly includes a second guide rail 43 and a fourth drive member 41 for driving the moving wheel 10 to rise and fall vertically. The second guide rail 43 and the fourth drive member 41 are both mounted on the frame 20. The second guide rail 43 and the fourth drive member 41 are both vertically arranged, and the pushing portion of the fourth drive member 41 suspends the moving wheel 10, and the moving wheel 10 is slidably arranged on the second guide rail 43. In this embodiment, the purpose of the adjustment assembly is also to drive the moving wheel 10 to rise and fall, so it can also be implemented by a hydraulic cylinder. The fourth drive member 41 in this embodiment and the third drive member 40 in the above embodiment are actually the same components. The first and second are only for the purpose of making a distinction in naming, and no other restrictions are made, including the subsequent first drive member 11 and the second drive member 52. The first and second are only for the purpose of making a distinction, and the types of their motors can be the same or different. The first guide rail 42 and the second guide rail 43 are both equipped with a stroke sensor to detect the stroke, and then transmit the information to the manipulator for processing and monitoring. Of course, in addition to using hydraulic cylinders for lifting, the other lifting methods mentioned above are also suitable for this embodiment and will not be described in detail here.

[0031] The above scheme is further optimized. The frame 20 and the lifting frame 3 described above can be square frames in their overall shape. The frame 20 is below the lifting frame 3 and is slightly larger in size so that the lifting frame 3 can completely enter the frame 20. In order to facilitate the lifting frame 3 to slide on the first guide rail 42 installed on the frame 20, an open support arm 30 is provided on one opposite side of the square frame-shaped lifting frame 3 (i.e., it is inclined). Preferably, the support arm 30 is also square and has a horizontal cross bar 31. The two ends of the cross bar 31 are respectively slidably set on two vertical guide rails. In this way, the support arm 30 and the square frame-shaped lifting frame 3 can completely enter the frame 20.

[0032] As an optimization solution of the embodiment of the present invention, please refer to Figure 1-2 There are multiple action wheels 10, and the adjustment components correspond to the action wheels 10 one by one. In this embodiment, each action wheel 10 is configured with an adjustment component. For example, when there are four action wheels 10, the configured adjustment component can adjust the suspension of each action wheel 10.

[0033] For details on the above walking device, please refer to Figure 1-2, the walking device includes a first driving member 11 for driving the moving wheel 10 to rotate, and the first driving member 11 is installed on the adjustment assembly. In this embodiment, the number of the moving wheels 10 is preferably four, which can ensure the stability of the vehicle body. Of course, it is also feasible to set other numbers of moving wheels 10, and this embodiment is not limited to this. The first driving member 11 can drive the moving wheel 10 to rotate. The first driving member 11 can use a reduction motor, or a planetary reducer built into the moving wheel 10, and the motor drives the planetary reducer to drive the moving wheel 10. Preferably, each moving wheel 10 can be equipped with a motor to achieve four-wheel drive movement and ensure stable driving in muddy areas.

[0034] As an optimization solution of the embodiment of the present invention, tracks are installed on the outer side of the moving wheel 10, or the moving wheel 10 is a triangular track wheel, and tracks are installed to make the chassis suitable for more complex working scenes. In order to adjust the working scene, a push bucket can also be configured, and the push bucket can be detachably installed on the chassis. Specifically, the push bucket is detachably connected to the frame 20, and it is assembled to the frame 20 when necessary, and the pushing direction of the push bucket is the same as the driving direction of the chassis. When it is not needed, it can be removed from the frame 20, and the push bucket is an optional accessory of the chassis.

[0035] See also Figure 1-2 The embodiment of the present invention provides a trenching and leveling vehicle, which includes a material taking device and the above-mentioned chassis, and the material taking device is installed on the lifting frame 3. In this embodiment, the material taking device used for material taking operation is installed on the lifting frame 3, so that the trenching and leveling vehicle can, on the one hand, change the vertical position of the lifting frame 3 through the driving component, so that after the chassis is applied to the trenching and leveling vehicle, it can maintain the same vertical direction to perform material taking operation on a certain fixed point, thereby improving the efficiency and accuracy of material taking; on the other hand, the height of the moving wheel 10 of the walking device can be adjusted in real time through the adjustment component, so as to facilitate walking in potholes and bumps. When necessary (such as transportation, long-term parking, maintenance or operation), the height of the moving wheel 10 can be adjusted to be higher than the height of the bottom of the frame 20, so that the frame 20 can be directly supported on the ground, thereby improving the stability of the frame 20.

[0036] As an optimization solution of the embodiment of the present invention, please refer to Figure 1-2 The lifting frame 3 is provided with a rotating mechanism for driving the material taking device to work. In this embodiment, the material taking operation is limited to taking materials during the rotation process. Of course, in addition to this, a digging method similar to that of an excavator is also a feasible method, which is not limited in this embodiment.

[0037] For details on the above rotation mechanism, see Figure 1-2The rotating mechanism includes a rotating transmission shaft 50 mounted on the lifting frame 3, a stabilizing wheel for positioning the material taking device, and a second driving member 52 for driving the rotating transmission shaft 50 to rotate. The stabilizing wheel is mounted on the rotating transmission shaft 50, and the rotating axis of the stabilizing wheel is coaxially arranged with the rotating axis of the rotating transmission shaft 50. In this embodiment, the second driving member 52 is a reduction motor, and the rotating method mainly adopts the rotating transmission shaft 50. First, the rotating transmission shaft 50 is driven to rotate by the second driving member 52, and then the rotating transmission shaft 50 rotates with the stabilizing wheel. Since the material taking device is positioned by the stabilizing wheel, the material taking operation can be performed with the material taking device during the rotation process. Of course, in addition to using these methods, the rotating method can also adopt an engine and a gearbox to connect the rotating transmission shaft 50, drive the rotating frame 60 to drive the hopper 61 to rotate, including but not limited to a chain, belt or gear transmission device, which is not limited in this embodiment. The ditching and leveling vehicle also includes a power supply system, which includes a power generation unit and a power storage unit, etc., which can be used to generate electricity to supply power to the vehicle's electrical equipment. The power generation unit includes a generator. The above-mentioned engine can also drive the generator at the same time. The generator supplies power to the power storage unit or other power units. Therefore, when the rotating frame is in a high position or the gearbox is in neutral, the engine is started to generate electricity. The generator supplies power to the hydraulic system to lower the rotating frame and after the gear is engaged, the gearbox drives the rotating transmission shaft 50.

[0038] To optimize the above mentioned stabilization wheels, see Figure 1-2 The stabilizing wheel is an H wheel 51 sleeved on the rotating transmission shaft 50, and the H wheel 51 has a positioning groove for the material taking device to partially extend into, and the H wheel 51 is in rolling contact with the material taking device. In this embodiment, the H wheel 51 is used as the stabilizing wheel, which can be rotated by the rotating transmission shaft 50, and has a positioning groove for the rotating frame 60 of the material taking device to partially extend into.

[0039] As an optimization solution of the embodiment of the present invention, please refer to Figure 1-2, there is at least one rotating transmission shaft 50 and all of them are mounted on the lifting frame 3, each of the rotating transmission shafts 50 is provided with the stabilizing wheel and the two are coaxially arranged; the stabilizing wheel installed on the rotating transmission shaft 50 is a driving wheel, which is fixed on the rotating transmission shaft 50, and the rotating transmission shaft 50 is installed on the lifting frame 3 through a bearing, and each of the stabilizing wheels is a driven wheel, and the output shaft of the second driving member 52 is connected to the driving wheel, and some of the driven wheels are connected to the driving wheel. In this embodiment, as shown in the above embodiment, the lifting frame 3 can be a square frame, then the rotating transmission shafts 50 here can preferably be four, respectively arranged on the four horizontal edges of the square frame, and these four edges form a square, so that the material taking device can have more installation positions, and it can also be more stable after installation. The driving wheel is an H wheel 51 sleeved on the rotating transmission shaft 50, and the H wheel 51 has a positioning groove for the material taking device to partially extend into, and the H wheel 51 is in rolling contact with the material taking device, while the other driven wheels can be rotatably mounted on the lifting frame 3 using bearings, specifically, the driven wheels are fixed on the corresponding outer rings of the bearings, and the inner rings of the bearings are fixed on the lifting frame 3. Still taking the four rotating transmission shafts 50 as an example, if each rotating transmission shaft 50 is equipped with a motor to drive it, the preparation cost of the vehicle will increase. Therefore, the working principle of the synchronous wheel can be adopted, and a chain 53 is used to connect two of the rotating transmission shafts 50. A sprocket that cooperates with the chain 53 is arranged on the rotating transmission shaft 50. One of them is driven by the second driving member 52, and the other is driven by the chain 53. As for the remaining two rotating transmission shafts 50, they can also be driven by the chain 53, or directly driven by the material taking device that is driven and in a rotating motion. Because the material taking device is rotating, the stabilizing wheel installed on it will definitely rotate accordingly, so the stabilizing wheel can rotate with the rotating transmission shaft 50. For chain transmission, belt or gear meshing can also be used for transmission, which is determined according to the specific product structure. This structural form can also be applied to the above-mentioned action wheel 10, specifically: a supporting frame is arranged inside the action wheel 10, and a plurality of stabilizing wheels are arranged on the supporting frame, and the action wheel 10 is positioned by supporting each of the stabilizing wheels, and one of the stabilizing wheels is a driving wheel, and the other stabilizing wheels are all driven wheels. The output shaft of the first driving member 11 is connected to the rotating shaft of the driving wheel, and some of the driven wheels are transmission-connected to the driving wheel. The transmission connection can adopt a sprocket chain, and of course each driven wheel can also be a follower. By adopting this structural form, a higher reduction ratio can be obtained, a smaller power source can be used, and the first driving member 11 occupies less space.

[0040] For details on the above-mentioned reclaiming device, please refer to Figure 1-2, the material taking device includes at least one hopper 61 and a rotating frame 60 driven to rotate by the rotating mechanism, the rotating frame 60 is installed on the stabilizing wheel, the hopper 61 rotates with the rotating frame 60, and the hopper 61 is provided with a taking tooth 62 that can dig materials during the rotation of the rotating frame 60, and the taking tooth 62 extends in the rotation direction of the rotating frame 60. In this embodiment, it mainly includes a rotating frame 60, the rotating frame 60 is driven to rotate by the above-mentioned driving mechanism, and the hopper 61 rotates the rotating frame 60, so that the ground can be dug during the rotation of the rotating frame 60, that is, the material taking operation is realized. In conjunction with the above-mentioned driving assembly, the lifting frame 3 can be gradually lowered to reduce the working height of the material taking device installed on the lifting frame 3, so that the material taking operation can be realized in the same vertical direction. In fact, the material taking operation mainly relies on the material taking teeth 62 provided on the hopper 61. The hopper 61 is used to temporarily store the excavated materials. Moreover, the trenching and leveling vehicle with such a structure can excavate synchronously during the moving process. For example, during the operation, the rotating frame 60 is lowered to collect materials, and the trenching and leveling vehicle travels at a slow speed. Preferably, the hopper 61 can be selected in different shapes according to different actual operation scenarios, such as V-shaped, U-shaped, etc.

[0041] To further optimize the above reclaiming device, please refer to Figure 1-2 There are multiple hoppers 61, each of which is arranged around the rotating frame 60. Each hopper 61 is provided with a material taking tooth 62, and each of the material taking teeth 62 extends in the same rotation direction of the rotating frame 60. In this embodiment, in order to improve the efficiency of taking materials, multiple hoppers 61 can be provided, so that during the rotation process, the number of excavations will increase after one rotation, which can greatly improve the efficiency of taking materials. Preferably, the hoppers 61 can be arranged around the rotating frame 60 at intervals and evenly.

[0042] To further refine the above-mentioned reclaiming device, please refer to Figure 1-2 The material taking device also includes a feeding mechanism for transporting the material taken out of the hopper 61 to the outside of the vehicle. In this embodiment, the feeding mechanism can facilitate the material taken out of the material taking device to be transported to a distant place, and in conjunction with the loading vehicle, synchronous loading can also be achieved, which greatly improves the working efficiency of the entire material taking operation.

[0043] For details on the above feeding mechanism, please refer to Figure 1-2The feeding mechanism includes an annular material blocking cover 80, a discharge bin 70 installed on the top of the material blocking cover 80, and a conveying assembly for transferring the material in the discharge bin 70. The hopper 61 is driven by the rotating frame 60 to rotate relative to the material blocking cover 80. The inner side surface of the hopper 61 has a notch and the notch is blocked by the material blocking cover 80. The discharge port of the discharge bin 70 is located directly above the conveying assembly, and the feed port of the discharge bin 70 is the opening on the top of the material blocking cover 80. In this embodiment, the material blocking cover 80 can block the accidentally leaked material outside the vehicle, or outside the driving component, the adjustment component and the rotating mechanism. When the hopper 61 on the rotating frame 60 is rotating, the material blocking cover 80 can block the material in the hopper 61 to prevent it from falling out from the gap. When the hopper 61 rotates to the highest point, it is just above the feed port of the discharge bin 70. At this time, the material falls into the discharge bin 70 through the gap, and then falls into the conveying component below it through the discharge port of the discharge bin 70 to be transported away. Preferably, the discharge bin 70 can be equipped with a controller that controls the opening or closing of the discharge port, so that the feeding mechanism is suitable for more working conditions. Of course, in addition to this method of synchronously transporting the material, the material can also be transported away in a single time or a single batch, and it is not necessary to transport the material synchronously in a coherent manner. This method is also feasible. This embodiment is not limited to this.

[0044] For details on the above conveyor components, please refer to Figure 1-2 The conveying assembly includes a conveyor belt 71, one side of which is located directly below the discharge port of the discharge bin 70, and the other side extends outside the vehicle. In this embodiment, the conveying assembly uses a conveyor belt 71, which can be docked with an external transport vehicle to load the material into the vehicle during the material collection process, so as to facilitate transportation out of the site. Of course, in addition to this, other separate transportation methods are also feasible, such as manually using a cart to push the material away. This embodiment is not limited to this.

[0045] As an optimization scheme of the embodiment of the present invention, the trenching and leveling vehicle also includes a control room for operators to operate and control. The trenching and leveling vehicle also includes a wired controller or a wireless remote control to control each component that needs to be controlled, such as controlling lifting and rotation, etc. Of course, it is still necessary to leave the vehicle for observation and control when necessary; the trenching and leveling vehicle also includes a navigation operation system, which uses the principles of "subtractive manufacturing" and "additive manufacturing" to automatically control the first drive member, the second drive member, the third drive member and the fourth drive member through the manipulator. The navigation operation system scans the operation area to generate a navigation 3D operation map, and the material layer is cut or transferred or raised in sequence according to the 3D operation map to finally complete the project. The chassis also includes at least one of a geodesic sensor and a horizontal sensor. For example, the driving wheel 10 of the trenching and leveling vehicle can be equipped with a geodesic sensor, and the frame 20 can be equipped with a horizontal sensor, and the detected information is transmitted to the manipulator for processing, so as to control each suspension lifting and lowering on the undulating road surface to keep the frame 20 stable, and control part of the first drive member 11 to rotate forward when turning, and part of the first drive member 11 to rotate slowly, not rotate or reverse, thereby changing the turning angle. The chassis also includes at least one of a geodesic sensor and a horizontal sensor. For example, the driving wheel 10 of the trenching and leveling vehicle can be equipped with a geodesic sensor, and the frame 20 can be equipped with a horizontal sensor. The detected information is transmitted to the manipulator for processing to control the lifting of each suspension on an uneven road surface to keep the frame 20 stable, and control part of the first driving member 11 to rotate forward when turning, and part of the first driving member 11 to rotate slowly, not rotate or reverse, thereby changing the turning angle.

The control software can be compatible with a variety of manipulators, a variety of operating systems, and a variety of communication methods.

The wireless methods include but are not limited to infrared, WIFI, Bluetooth, GPRS, ZigBee, 2.4GHz, 5GHz, 60GHz, 3G, 4G, 5G, 6G, etc. The running status of the vehicle can be monitored and adjusted through the remote manipulator to meet the short-range or remote work of the vehicle.

[0047] The controller used here includes a device with a wireless signal receiver, a device with a wireless signal receiver without transmission capability, and a receiving and transmitting hardware device, which has a receiving and transmitting hardware device capable of performing two-way communication on a two-way communication link.
