Description

Technical Field

[0001] This invention relates to the field of engineering machinery, specifically to a parking assist device and an engineering vehicle. Background Technology

[0002] Construction machinery operates in complex and varied mountainous environments, requiring it to work in plains, mountains, deserts, hills, swamps, snowfields, and other terrains.

[0008] A roller includes a cylindrical body and a protrusion fixed to the outer wall of the cylindrical body; the cylindrical body includes a through hole extending through its own axial direction; and

[0009] A speed reducer is installed in the through hole, with both ends of the speed reducer extending out of the through hole; one end of the speed reducer is supported by the other end of the first crossbeam, and the other end of the speed reducer is supported by the other end of the second crossbeam.

[0010] In some embodiments, the anchoring mechanism includes:

[0011] The mounting bracket includes a first connecting rod, a second connecting rod, and a mounting rod; one end of the first connecting rod is rotatably connected to one of the second driving mechanisms, and the other end of the first connecting rod is fixedly connected to the mounting rod; one end of the second connecting rod is rotatably connected to the other second driving mechanism, and the other end of the second connecting rod is fixedly connected to the mounting rod; and

[0012] Multiple insertion ends are installed in a row on the mounting rod.

[0013] In some embodiments, the first connecting rod includes:

[0014] The first segment, one end of which is drivenly connected to one of the second drive mechanisms; and

[0015] The second segment has one end fixedly connected to the other end of the first segment, and the included angle between the first segment and the second segment is an obtuse angle. The protruding side of the connection between the first segment and the second segment is rotatably connected to the first crossbeam. The other end of the second segment away from the first segment is fixedly connected to the mounting rod.

[0016] In some embodiments, the second connecting rod includes:

[0017] The third segment, one end of which is drivenly connected to another of the second driving mechanisms; and

[0018] The fourth segment has one end fixedly connected to the other end of the third segment, and the included angle between the third segment and the fourth segment is an obtuse angle. The protruding side of the connection between the third segment and the fourth segment is rotatably connected to the second crossbeam. The other end of the fourth segment away from the third segment is fixedly connected to the mounting rod.

[0019] In some embodiments, the parking assist device is configured to be symmetrical and arranged symmetrically with respect to the cross-section at the midpoint of the central axis of the roller assembly.

[0020] This invention provides an engineering vehicle, including a vehicle body and a parking assist device provided by any of the technical solutions of this invention. The parking assist device is installed at the rear end of the vehicle body.

[0021] In some embodiments, when the engineering vehicle is traveling on flat ground, the first drive mechanism drives the booster mechanism to lift up, and the second drive mechanism drives the anchoring mechanism to lift up, so that both the booster mechanism and the anchoring mechanism leave the ground.

[0025] The parking assist device provided by the above technical solution includes an assist mechanism and an anchoring mechanism. The assist mechanism can be driven to rotate by a first drive mechanism, and the anchoring mechanism can be driven to rotate by a second drive mechanism. When it is necessary to securely park the engineering vehicle on a slope, the first drive mechanism allows the assist mechanism to contact the slope surface while remaining stationary, and the second drive mechanism allows the anchoring mechanism to contact the slope surface. When it is necessary to drive the engineering vehicle on a slope, the first drive mechanism allows the assist mechanism to contact the slope surface, and the assist mechanism is in a driven state. The assist mechanism can assist in increasing the driving force of the engineering vehicle, making the engineering vehicle have more power and smoother when going up the slope, and also enabling the engineering vehicle to meet the requirements of driving on steeper slopes. When it is necessary to drive the engineering vehicle on flat ground, both the assist mechanism and the anchoring mechanism are away from the ground, so that the engineering vehicle can be easily transferred and transported using its own driving system. It is evident that the above technical solution can increase the friction between the engineering vehicle and the slope as needed, making the vehicle more stable when operating on the slope and also increasing the power of the engineering vehicle to go uphill. It is highly practical and economical, and easy to control. Attached Figure Description

[0034] The following is combined with Figures 1-5 The technical solutions provided by this invention will be described in more detail below. The descriptions of exemplary embodiments are merely illustrative and are in no way intended to limit this disclosure or its application or use. This disclosure can be implemented in many different forms and is not limited to the embodiments described herein.

When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may be not directly connected to the other devices but have an intermediary device.

[0037] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] The dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Common structural elements or elements of the same kind are given the same reference numerals in the various drawings, and repeated descriptions of them are omitted where appropriate.

[0040] For ease of description, the following directions are defined in the embodiments described below: the length direction of the frame is L, and the width direction of the frame is W. The width direction of the mounting beam assembly 11 is the same as the width direction of the frame and also the same as the axial direction of the roller 121 of the roller assembly 12.

[0041] See Figure 1 This invention provides a parking assist device, including an assist mechanism 1, a first drive mechanism 2, a second drive mechanism 3, and an anchoring mechanism 4. The assist mechanism 1 includes a mounting beam assembly 11 and a roller assembly 12; the roller assembly 12 is rotatably mounted on the mounting beam assembly 11. The first drive mechanism 2 is drivenly connected to the mounting beam assembly 11 to drive the mounting beam assembly 11 to rotate. The second drive mechanism 3 is mounted on the mounting beam assembly 11. The anchoring mechanism 4 is drivenly connected to the second drive mechanism 3 to rotate under the drive of the second drive mechanism 3.

[0042] The parking assist device is symmetrical as a whole, with the plane of symmetry being the plane passing through the axial center of the roller assembly 12. The parking assist device is installed at the rear of the vehicle body 5. Because the parking assist device has a symmetrical structure, the force on the vehicle along its width direction W is balanced.

[0043] See Figure 1 The first drive mechanism 2 is used to drive the booster mechanism 1 to pitch, thereby changing the angle of the booster mechanism 1 relative to the ground, so that the booster mechanism 1 can be in contact with the ground or away from the ground. The first drive mechanism 2 is located between the roller assembly 12 and the vehicle body 5.

[0044] One end A1 of the first drive mechanism 2 is rotatably connected to the vehicle frame, and the other end B1 is rotatably connected to the mounting beam assembly 11 of the booster mechanism 1. The number of first drive mechanisms 2 can be one, two, or more than two. In some embodiments of the present invention, the number of first drive mechanisms 2 is one, and the first drive mechanism 2 is installed at the middle of the width direction of the mounting beam assembly 11. Here, the width direction of the mounting beam assembly 11 is the same as the width direction of the vehicle frame. The first drive mechanism 2 can adopt pneumatic, hydraulic, or electric drive forms. In some embodiments, the first drive mechanism 2 adopts a hydraulic cylinder. The hydraulic oil source for the hydraulic cylinder can be the hydraulic system of the engineering vehicle. This configuration eliminates the need for additional power sources, making the structure of the engineering vehicle more compact and requiring fewer components.

[0045] See also Figure 1 The mounting beam assembly 11 is a load-bearing component of the roller assembly 12 and also a load-bearing component of the anchoring mechanism 4. In some embodiments, the mounting beam assembly 11 includes a first crossbeam 111, a second crossbeam 112, and an intermediate beam 113. One end A2 of the first crossbeam 111 is configured to be rotatably connected to the vehicle body 5, and the other end B2 of the first crossbeam 111 is fixedly connected to the first axial end A3 of the roller assembly 12. One end A4 of the second crossbeam 112 is configured to be rotatably connected to the vehicle body 5, and the other end B4 of the second crossbeam 112 is fixedly connected to the second axial end B3 of the roller assembly 12. The intermediate beam 113 is located between the first crossbeam 111 and the second crossbeam 112; one end of the intermediate beam 113 is fixedly connected to the first crossbeam 111, and the other end of the intermediate beam 113 is fixedly connected to the second crossbeam 112; the first drive mechanism 2 is drivenly connected to the intermediate beam 113. The mounting beam assembly 11 can be made of a lightweight and wear-resistant material to improve its service life.

[0046] The first crossbeam 111, the second crossbeam 112, and the intermediate beam 113 form an I-beam structure, ensuring structural stability and reliability. The intermediate beam 113 is located near the other end of the first crossbeam 111 and the other end of the second crossbeam 112, providing more space for the installation of the first drive mechanism 2. The roller assembly 12 is situated between the first crossbeam 111 and the second crossbeam 112. The axial direction of the roller assembly 12 is parallel to the longitudinal direction of the intermediate beam 113.

[0047] The other end B2 of the first crossbeam 111 has a first mounting hole 1110, and one end of the reducer 122 of the roller assembly 12 is installed in the first mounting hole 1110. The other end B2 of the first crossbeam 111 supports the first end A3 of the roller assembly 12 in the axial direction. The other end B3 of the second crossbeam 112 has a second mounting hole 1120, and the other end of the reducer 122 of the roller assembly 12 is installed in the second mounting hole 1120. The other end B4 of the second crossbeam 112 supports the second end B3 of the roller assembly 12 in the axial direction.

[0048] See Figure 1 The roller assembly 12 includes a roller 121 and a reducer 122. The roller 121 includes a cylinder 121a and a protrusion 121b fixed to the outer wall of the cylinder 121a; the cylinder 121a includes a through hole 121c extending through its own axial direction. The reducer 122 is installed in the through hole 121c, with both ends of the reducer 122 extending out of the through hole 121c; one end of the reducer 122 is supported by the other end of a first crossbeam 111, and the other end of the reducer 122 is supported by the other end of a second crossbeam 112.

[0049] The roller 121 is cylindrical, with a through hole 121c extending through its axial direction. Multiple protrusions 121b, each a rectangular block structure, are provided on the outer surface of the roller 121. These protrusions 121b are arranged in rows along the axial direction of the roller 121. Multiple rows of protrusions 121b are arranged around the circumference of the roller 121. Gaps exist between adjacent protrusions 121b in the same row and between adjacent rows of protrusions 121b. These gaps allow the roller assembly 12 to be inserted into the soil, ensuring a secure clamping between the roller assembly 12 and the ground. By controlling the insertion depth of the protrusions 121b, the protrusions 121b can be positioned only shallowly on the ground surface, allowing the roller assembly 12 to rotate relative to the ground. The relative position of the protrusions 121b of the roller assembly 12 and the ground is controlled by the first drive mechanism 2. The first drive mechanism 2 uses a hydraulic cylinder. The longer the cylinder extends, the greater the angle at which the roller assembly 12 is raised, and the greater the distance between the roller assembly 12 and the ground. Conversely, the shorter the cylinder extends, the smaller the angle at which the roller assembly 12 is raised, and the closer the distance between the roller assembly 12 and the ground. The relative position of the roller assembly 12 and the ground can be controlled by adjusting the extension length of the first drive mechanism 2.

[0050] It should be noted that since the booster mechanism 1 is the supporting component of the second drive mechanism 3 and the anchoring mechanism 4, when the first drive mechanism 2 drives the booster mechanism 1 to pitch, the second drive mechanism 3 installed on the booster mechanism 1 and the anchoring mechanism 4 driven by the second drive mechanism 3 will also pitch accordingly.

[0051] There are two second drive mechanisms 3. One end A5 of one second drive mechanism 3 is rotatably connected to the first crossbeam 111, and the other end B5 of the second drive mechanism 3 is rotatably connected to the anchoring mechanism 4. One end A6 of the other second drive mechanism 3 is rotatably connected to the second crossbeam 112, and the other end B6 of the second drive mechanism 3 is rotatably connected to the anchoring mechanism 4.

[0052] Both second drive mechanisms 3 can be pneumatic, hydraulic, or electric drive mechanisms. In some embodiments, both second drive mechanisms 3 are hydraulic cylinders. The cylinder barrel end of the hydraulic cylinder is rotatably connected to the first crossbeam 111 and the second crossbeam 112, and the piston end of the hydraulic cylinder is rotatably connected to the first connecting rod 411 and the second connecting rod 412. To make the pitch angle of the first connecting rod 411 and the second connecting rod 412 controllable, the bend of the first connecting rod 411 is rotatably connected to the other end B2 of the first crossbeam 111, and the bend of the second connecting rod 412 is rotatably connected to the other end B3 of the second crossbeam 112. The two second drive mechanisms 3 are located above the top of the roller assembly 12.

[0053] See also Figure 1In some embodiments, the first connecting rod 411 includes a first segment 411a and a second segment 411b. One end of the first segment 411a is drivenly connected to one of the second driving mechanisms 3. One end of the second segment 411b is fixedly connected to the other end of the first segment 411a, and the included angle between the first segment 411a and the second segment 411b is an obtuse angle. The protruding side of the connection between the first segment 411a and the second segment 411b is rotatably connected to the first crossbeam 111. The other end of the second segment 411b away from the first segment 411a is fixedly connected to the mounting rod 413. Both the first segment 411a and the second segment 411b can be straight rods, and the first segment 411a and the second segment 411b can be integral or welded together. The length of the first segment 411a is less than the length of the second segment 411b. The connection between the first segment 411a and the second segment 411b is located at the other end of the first crossbeam 111. The connection between the first segment 411a and the second segment 411b is rotatably connected to the other end B2 of the first crossbeam 111 through components such as a connecting plate and a pin.

[0054] See also Figure 1 In some embodiments, the second connecting rod 412 includes a third segment 412a and a fourth segment 412b. One end of the third segment 412a is drivenly connected to another second driving mechanism 3. One end of the fourth segment 412b is fixedly connected to the other end of the third segment 412a, and the included angle between the third segment 412a and the fourth segment 412b is an obtuse angle. The protruding side of the connection between the third segment 412a and the fourth segment 412b is rotatably connected to the second crossbeam 112; the other end of the fourth segment 412b away from the third segment 412a is fixedly connected to the mounting rod 413. Both the third segment 412a and the fourth segment 412b can be straight rods, and they can be integral or welded together. The length of the third segment 412a is less than the length of the fourth segment 412b. The connection between the third segment 412a and the fourth segment 412b is located at the other end of the second crossbeam 112. The connection between the third segment 412a and the fourth segment 412b is rotatably connected to the other end B3 of the second crossbeam 112 through components such as connecting plates and pins.

[0055] See also Figure 1 In some embodiments, the anchoring mechanism 4 includes a mounting frame 41 and a plurality of insertion ends 42. The mounting frame 41 includes a first connecting rod 411, a second connecting rod 412, and a mounting rod 413; one end of the first connecting rod 411 is rotatably connected to one of the second driving mechanisms 3, and the other end of the first connecting rod 411 is fixedly connected to the mounting rod 413; one end of the second connecting rod 412 is rotatably connected to another second driving mechanism 3, and the other end of the second connecting rod 412 is fixedly connected to the mounting rod 413. The plurality of insertion ends 42 are arranged in a row on the mounting rod 413. Each insertion end 42 is approximately toothed, with a gap between adjacent insertion ends 42, allowing for easier insertion into the ground.

[0056] Driven by the second drive mechanism 3, the anchoring mechanism 4 can rotate to a position where the insertion end 42 is higher than the roller assembly 12, such as... Figure 3 and Figure 4 As shown; it can also be rotated so that the insertion end 42 is below the position of the roller assembly 12, as shown. Figure 5 As shown, the anchoring mechanism 4 has a first connecting rod 411 and a second connecting rod 412 at two positions along the length of the mounting rod 413, which makes the force on the anchoring mechanism 4 more balanced and the movement more stable during lifting.

[0057] See Figures 2 to 5 This invention provides an engineering vehicle, including a vehicle body 5 and a parking assist device provided by any of the technical solutions of this invention. The parking assist device is installed at the rear end of the vehicle body 5.

[0058] The engineering vehicles can specifically include pipe-transporting machines, welding vehicles, and other engineering machinery. These vehicles can be used in steep slope conditions, such as slopes with angles ranging from 15° to 30°. This greatly expands the application range of engineering vehicles, improves their climbing ability, slope stability and safety, solves the problems of construction on steep slopes, reduces construction costs, and protects the natural environment.

[0059] See Figure 3 In some embodiments, when the engineering vehicle is traveling on flat ground 6, the first drive mechanism 2 drives the booster mechanism 1 to lift up, and the second drive mechanism 3 drives the anchoring mechanism 4 to lift up, so that both the booster mechanism 1 and the anchoring mechanism 4 leave the ground.

[0060] When driving on a flat road, the first drive mechanism 2 retracts, the roller assembly 12 is raised away from the ground, and at the same time the second drive mechanism 3 retracts, driving the anchoring mechanism 4 to continue to rise. The entire booster device is located outside the vehicle's ground angle range, which meets the requirement of climbing steep slopes without collision.

[0061] from Figure 3 As can be seen, when traveling on flat ground 6, the booster mechanism 1 is driven away from the ground by the first drive mechanism 2, and the anchoring mechanism 4 is lifted off the ground along with the booster mechanism 1 and also driven away by the second drive mechanism 3. Therefore, the anchoring mechanism 4 is also away from the ground. Under this condition, neither the booster mechanism 1 nor the anchoring mechanism 4 functions.

[0062] from Figure 3 It can also be seen that under this working condition, the anchoring mechanism 4 is far away from the working platform of the engineering vehicle, and the anchoring mechanism 4 will not interfere with the working platform of the engineering vehicle.

[0063] See Figure 4In some embodiments, when the engineering vehicle is traveling on the ramp 7, the first drive mechanism 2 drives the booster mechanism 1 to rotate so that the roller assembly 12 contacts the ground of the ramp 7, and the second drive mechanism 3 drives the anchoring mechanism 4 to lift so that the anchoring mechanism 4 leaves the ground of the ramp 7. In this condition, the engineering vehicle travels on the steep ramp 7. The first drive mechanism 2 extends, the roller assembly 12 is in contact with the ground, and at the same time, the second drive mechanism 3 continues to retract, causing the anchoring mechanism 4 to continue to lift. The reducer 122 of the roller assembly 12 is activated, causing the roller assembly 12 to rotate and, in conjunction with the track beam traveling mechanism, provide a powerful boost for the entire machine to ascend the ramp.

[0064] from Figure 4 As can be seen, when traveling on ramp 7, the protrusions 121b on the outer surface of the roller 121 of the roller assembly 12 can contact the ground. As the roller 121 rotates, the protrusions 121b at different circumferential positions of the roller assembly 12 continuously contact the ground, increasing the friction between the roller assembly 12 and the ground. Therefore, under this condition, the roller assembly 12 can play at least two roles: the roller assembly 12 itself rotates under the drive of the reducer 122, increasing the driving force for the engineering vehicle to go uphill, and also increasing the friction between the engineering vehicle and the ground of ramp 7, preventing the engineering vehicle from slipping or rolling backward.

[0065] from Figure 4 It can also be seen that under this condition, the anchoring mechanism 4 is lifted by the second drive mechanism 3, and the anchoring mechanism 4 is away from the ground of the ramp 7. The anchoring mechanism 4 is inactive at this time. Under this condition, the anchoring mechanism 4 is also away from the working platform of the engineering vehicle, and the anchoring mechanism 4 will not interfere with the working platform of the engineering vehicle.

[0066] See Figure 5 In some embodiments, when the engineering vehicle is operating on the ramp 7, the first drive mechanism 2 drives the booster mechanism 1 to rotate so that the roller assembly 12 of the booster mechanism 1 contacts the ground of the ramp 7, and the second drive mechanism 3 drives the anchoring mechanism 4 to rotate so that the anchoring mechanism 4 contacts the ground of the ramp 7.

[0067] When the engineering vehicle stops and operates on the steep slope 7, the engineering vehicle stops moving. At this time, the first drive mechanism 2 extends, the roller assembly 12 is in contact with the ground, and the second drive mechanism 3 continues to extend, keeping the anchoring mechanism 4 pressed down and embedded below the ground. At the same time, the reducer 122 of the roller assembly 12 is turned off to increase the ground contact range of the whole vehicle and improve the stability of the whole vehicle operation.

[0068] from Figure 5As can be seen, under this working condition, the protrusion 121b on the outer surface of the roller 121 of the roller assembly 12 remains in contact with the ground, and the insertion end 42 of the anchoring mechanism 4 is also inserted into the ground. Both the roller assembly 12 and the anchoring mechanism 4 can increase the friction between the engineering vehicle and the road surface of the ramp 7, making the engineering vehicle more stably parked on the ramp 7, and making the engineering vehicle more stable and reliable when operating on the ramp 7.

[0069] In some embodiments, when the engineering vehicle is operating on the ramp 7, the reducer 122 of the roller assembly 12 is in a stopped state, and the roller 121 of the roller assembly 12 is in contact with the ground of the ramp 7 to increase the friction between the engineering vehicle and the road surface of the ramp 7.

[0070] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
