[0033] The following combination Figures 1-10 , the special operation vehicle provided by the embodiment of the present invention is described in detail through specific embodiments and application scenarios.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment provides a special operation vehicle, including: an operation platform 1, a boom 2, a walking chassis 3, a frame 4 and a leg support assembly 5.

[0035] The top of the boom 2 is connected to the working platform 1 ; the boom 2 is connected to the traveling chassis 3 , and the boom 2 can be telescopic relative to the traveling chassis 3 ; the frame 4 is connected to the traveling chassis 3 .

[0036] The leg support assembly 5 is arranged on the front and rear sides of the frame 4 along the walking direction of the walking chassis 3. The leg support assembly 5 includes a telescopic support member 51 and a lifting member 52. One end of the telescopic support member 51 is arranged on the frame 4, and the other end of the telescopic support member 51 is connected to the lifting member 52. The lifting member 52 is arranged vertically to the telescopic support member 51. The lifting member 52 is used to drive the lifting and lowering of the telescopic support member 51 to lift the walking chassis 3 and the frame 4 off the ground, and drive the walking chassis 3 to move under the drive of the telescopic support member 51.

[0037] It is understood that during aerial work, workers are lifted to a specific height using a special operation vehicle to perform aerial work on utility poles, building exterior walls, industrial tower furnace maintenance, high-altitude outdoor installation, orchard picking, etc. The work platform 1 is used to carry workers and is located on top of the boom 2. The work platform 1 generally includes a base, a hanging basket, and a mounting frame. The mounting frame is connected to the top of the boom 2. The base is mounted on the mounting frame, and the hanging basket is installed around the base to provide protection for workers from all heights around the base.

[0038] The boom 2 is connected to the walking chassis 3. The boom 2 is a telescopic arm setting. According to the specific height reached by the work platform 1, the extension of the boom 2 is adjusted so that the work platform 1 can deliver the staff to a specific location. When retracted, the body of the special work vehicle is folded to a smaller size, which is convenient for the special work vehicle to travel.

[0039] The traveling chassis 3 is a chassis equipped with a drive device that can autonomously drive the special operation vehicle and change its speed and direction, improving its maneuverability. The frame 4 is connected to the traveling chassis 3 and provides a mounting support for the outrigger support assembly 5.

[0040] The lifting member 52 of this embodiment can achieve vertical lifting to drive the telescopic support member 51 to move in the vertical direction, thereby adjusting the height of the telescopic support member 51 from the ground. Specifically, the lifting member 52 can be a telescopic rod, a screw assembly, or a slide rail and slider mechanism.

[0041] The telescopic support member 51 of this embodiment can be telescopic in the horizontal direction to drive the lifting member 52 to move in the horizontal direction and adjust the horizontal distance between the lifting member 52 and the frame 4. Specifically, the telescopic support member 51 can be a telescopic rod, a screw assembly, or a slide rail and slider mechanism.

[0042] When the special operation vehicle is in motion, the outrigger support device is folded on the frame 4 and moves with the traveling chassis 3. When the special operation vehicle needs to overcome an obstacle, the outrigger support device is deployed to support the traveling chassis 3 and overcome the obstacle. When the special operation vehicle is in operation, the outrigger support device is deployed to support the traveling chassis 3, achieving stable support for the traveling chassis 3 and the vehicle body.

[0043] Specifically, the front and rear sides of the running chassis 3 of this embodiment are both equipped with outrigger support assemblies 5. When an obstacle needs to be overcome, the running chassis 3 first faces the obstacle and stops moving. The telescopic support member 51 on the front side of the running chassis 3 extends forward to cross the obstacle, while the telescopic support member 51 on the rear side of the running chassis 3 extends a short distance backward to avoid the wheels of the running chassis 3. Then, the lifting member 52 at the end of the telescopic support member 51 descends vertically to contact the ground and continues to descend to lift the running chassis 3 off the ground, lifting the entire special operation vehicle off the ground. Next, the front telescopic support member 51 retracts, and the rear telescopic support member 51 extends, pushing the running chassis 3 and frame 4 from above the obstacle and over it. Finally, the lifting member 52 descends so that the wheels touch the ground, and the lifting member 52 and telescopic support member 51 retract to complete the obstacle overcome.

[0044] There are two ways to set up special operation vehicles, such as Figure 1 As shown, in the first configuration, the boom 2 is fixedly connected to the chassis 3, and the frame 4 is rotatably connected to the chassis 3. Driven by the frame 4, the outrigger support assembly 5 can rotate relative to the chassis 3, thereby adjusting the obstacle crossing angle and achieving a 360° obstacle crossing. In operation, the chassis 3 rotates synchronously with the boom 2.

[0045] like Figure 2 As shown, in the second configuration, the boom 2 is rotatably connected to the chassis 3, and the frame 4 is fixedly connected to the chassis 3. The boom 2 can rotate relative to the chassis 3, enabling flexible adjustment in different directions to expand the load area. Because the frame 4 is fixedly connected to the chassis 3, the outrigger support assembly 5 can cross obstacles in the direction of travel of the chassis 3. In the operating state, the boom 2 can rotate relative to the chassis 3.

[0046] The special operation vehicle provided by the present invention is provided with an operation platform 1, a boom 2, a walking chassis 3, a frame 4 and an outrigger support assembly 5. The boom 2 is connected to the walking chassis 3 and is retractably arranged on the walking chassis 3. The top of the boom 2 is connected to the operation platform 1, and the staff can perform high-altitude operations on the operation platform 1. In addition, by providing the frame 4 and the outrigger support assembly 5, the outrigger support assembly 5 includes a telescopic support member 51 and a lifting member 52. Through the lifting action of the lifting member 52 and the horizontal extension and contraction of the telescopic support member 51, the special operation vehicle is lifted from the ground and moved from the upper side of the obstacle to cross the obstacle. The operation is convenient and the efficiency of obstacle crossing is high.

[0047] like Figure 3 and Figure 4 As shown, along the moving direction of the walking chassis 3, telescopic support members 51 are provided at both ends of the front side of the frame 4 and both ends of the rear side of the frame 4 in this embodiment, and each telescopic support member 51 is provided in a one-to-one correspondence with the corresponding lifting member 52.

[0048] It can be understood that a telescopic support member 51 is provided at each end of the front and rear sides of the frame 4, and the force on the walking chassis 3 can be distributed around the chassis, so that when the walking chassis 3 is lifted off the ground using the lifting member 52, the walking chassis 3 can be evenly stressed, ensuring the stability and reliability of the walking chassis 3 when it is lifted and lowered in the height direction.

[0049] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the telescopic support member 51 of this embodiment includes a first leg cylinder.

[0050] The first outrigger oil cylinder includes a first cylinder barrel, a first piston and a first piston rod.

[0051] The first cylinder is fixedly connected to the frame 4 , the first piston is movably provided in the first cylinder, one end of the first piston rod is connected to the first piston, the first piston rod is passed through the first cylinder, and the other end of the first piston rod is connected to the lifting member 52 .

[0052] It is understandable that the first piston rod moves relative to the first cylinder, and the first piston rod drives the lifting member 52 to move horizontally relative to the frame 4, thereby adjusting the horizontal distance between the lifting member 52 and the frame 4.

[0053] Since the first leg cylinder can provide stable supporting force and the extension and retraction speed and position of the first leg cylinder can be accurately controlled by the hydraulic control system, the horizontal position of the lifting member 52 can be accurately adjusted to meet the requirements of different working heights.

[0054] like Figure 1 、 Figure 2 、 Figure 3and Figure 4 As shown, the lifting member 52 of this embodiment includes a second leg cylinder.

[0055] The second outrigger oil cylinder includes a second cylinder barrel, a second piston and a second piston rod.

[0056] The second cylinder is fixedly connected to the telescopic support 51, the second piston is movably provided in the second cylinder, one end of the second piston rod is connected to the second piston, the second piston rod is passed through the second cylinder, and the other end of the second piston rod is provided with a support plate.

[0057] It is understandable that the second piston rod moves relative to the second cylinder, and the second piston rod drives the support plate to move vertically relative to the telescopic support member 51 , thereby adjusting the vertical spacing of the support plate relative to the frame 4 .

[0058] Since the second leg cylinder can provide stable supporting force, and the extension and retraction speed and position of the second leg cylinder can be accurately controlled by the hydraulic control system, the vertical position of the lifting member 52 can be accurately adjusted, and effective support for the walking chassis 3 can be achieved.

[0059] Furthermore, since the support plate can automatically level itself to adapt to complex road conditions such as slopes, it ensures that the special operation vehicle can maintain a stable operating posture even on uneven ground to adapt to complex terrain in different situations.

[0060] like Figure 5 and Figure 6 As shown, in this embodiment, at least one of two adjacent telescopic support members 51 is movably provided on the frame 4 along the width direction of the traveling chassis 3 so as to be closer to or farther away from the center of the frame 4 .

[0061] It is understandable that the operating site of special operation vehicles is usually limited. For example, when the substation power grid is being repaired, the substation poles are densely arranged, the narrowest distance between the poles is less than 3 meters, the cables above the poles are dense, and the minimum height from the ground is only 2.3 meters. When driving and turning, the length, width and height of the operation vehicle are all limited; when parking, the narrow site also requires the operation vehicle to reach the maximum operating height or the maximum extended width as much as possible within the limited working space.

[0062] In this embodiment, one of the two adjacent telescopic supports 51 can be moved relative to the frame 4. When space is limited and the special operation vehicle has a large turning radius, the traveling chassis 3 cannot achieve large steering angles. In this case, the special operation vehicle is lifted off the ground using the lifting member 52. Since the traveling chassis 3 and the frame 4 are connected by the inner and outer rings of the slewing bearing, they can rotate 360° relative to each other. Adjusting the rotation angle of the slewing bearing inner ring can adjust the steering angle of the traveling chassis 3. The lifting member 52 is then retracted, allowing the tires to touch the ground, and the special operation vehicle can now achieve steering in a narrow space. This method greatly improves the special operation vehicle's ability to maneuver through narrow spaces.

[0063] This embodiment can flexibly select the area of the bearing zone according to the space conditions on site by adjusting the distance between two adjacent telescopic support members 51. It can adapt to narrow spaces and can be flexibly adjusted, and has high universality.

[0064] like Figure 5 and Figure 6 As shown, this embodiment further includes a hydraulic cylinder 6.

[0065] There are four hydraulic cylinders 6 , which are arranged on the frame 4 , and the output end of each hydraulic cylinder 6 is connected to the corresponding telescopic support member 51 .

[0066] Along the width direction of the traveling chassis 3, the two hydraulic cylinders 6 are opened and closed synchronously.

[0067] It is understood that the hydraulic cylinder 6 is used to drive the position of the telescopic support member 51 on the traveling chassis 3, so that the telescopic support member 51 can move in the width direction. Since four hydraulic cylinders 6 are provided for the four telescopic supports 51, the telescopic supports 51 can be driven to move quickly, improving the efficiency of adjusting the spacing of the telescopic supports 51.

[0068] Specifically, the two hydraulic cylinders 6 in the width direction of the traveling chassis 3 are set to open and close synchronously, the telescopic support member 51 can be moved closer or farther away synchronously, and then the lifting member 52 can be opened and closed synchronously, ensuring uniform adjustment of the working area.

[0069] like Figure 3 and Figure 4 As shown, the telescopic support member 51 of this embodiment includes a plurality of first leg oil cylinders, and the plurality of first leg oil cylinders are connected end to end in sequence to achieve multi-stage telescopic extension.

[0070] It is understandable that since the telescopic distance of the outrigger oil cylinder is limited, in scenarios where there is a greater demand for the telescopic amount, this embodiment sets multiple first outrigger oil cylinders for assembly to expand the telescopic amount, thereby increasing the adjustment distance of the telescopic support 51 in the horizontal direction.

[0071] Specifically, the piston rod of the previous first-leg cylinder is connected to the cylinder of the next first-leg cylinder. The piston rod of the previous one extends first, and after reaching its stroke, the piston rod of the next one extends. The total stroke is the sum of the two piston rods. In this way, multiple first-leg cylinders can be installed in series to achieve cumulative telescopic stroke and expand the adjustment range.

[0072] like Figure 3 and Figure 4 As shown, the lifting member 52 of this embodiment includes a plurality of second leg oil cylinders, and the plurality of second leg oil cylinders are connected end to end in sequence to achieve multi-stage telescopic extension.

[0073] It is understandable that since the telescopic distance of the outrigger cylinder is limited, in scenarios where there is a greater demand for the telescopic amount, this embodiment provides a plurality of second outrigger cylinders for assembly to expand the telescopic amount, thereby increasing the adjustment distance of the lifting member 52 in the vertical direction.

[0074] Specifically, the piston rod of the previous second-leg cylinder is connected to the cylinder of the next second-leg cylinder. The piston rod of the previous one extends first, and after reaching its stroke, the piston rod of the next one extends. The total stroke is the sum of the two piston rods. In this way, multiple second-leg cylinders can be installed in series to achieve cumulative telescopic stroke and expand the adjustment range.

[0075] like Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, the special operation vehicle of this embodiment further includes: a first rotary support member 7.

[0076] The boom 2 is fixedly connected to the traveling chassis 3, and the frame 4 is rotatably connected to the traveling chassis 3.

[0077] The frame 4 and the walking chassis 3 are connected through the first swivel support 7. The inner ring of the first swivel support 7 is fixed to the walking chassis 3. The frame 4 is provided with a first mounting hole. The first mounting hole is sleeved on the outer ring of the first swivel support 7. The outer ring of the first swivel support 7 is rotatably provided on the inner ring.

[0078] It is understood that the provision of the first slewing support 7 enables the frame 4 to rotate 360° relative to the chassis 3, thereby adjusting the frame 4's posture and direction. Especially when the special operation vehicle is in motion and the passage space is relatively narrow, the outrigger support assembly 5 can be driven to lift the chassis 3 off the ground. At this time, the frame 4 remains stationary, the boom 2 and chassis 3 are driven to rotate. After the chassis 3 rotates to a predetermined angle, the outrigger support assembly 5 is driven to lower the chassis 3 back to the ground. The outrigger support assembly 5 retracts the chassis 3 until it contacts the ground, thereby achieving flexible steering in narrow spaces. Therefore, the structure in which the frame 4 can rotate 360° relative to the chassis enables the special operation vehicle to both traverse obstacles 360° and steer 360° in confined spaces.

[0079] Specifically, the first rotary support member 7 can be a turntable, the inner ring of the turntable is fixed to the walking chassis 3, the mounting hole of the frame 4 is sleeved with the outer ring of the turntable, and the rotation of the outer ring relative to the inner ring realizes the rotation of the frame 4 relative to the walking chassis 3.

[0080] like Figure 2 and Figure 10 As shown, the special operation vehicle of this embodiment further includes: a second rotary support member 8.

[0081] The boom 2 is rotatably connected to the traveling chassis 3 , and the frame 4 is fixedly connected to the traveling chassis 3 .

[0082] The boom 2 and the walking chassis 3 are connected through a second slewing support 8. The inner ring of the second slewing support 8 is fixed to the boom 2. The walking chassis 3 is provided with a second mounting hole. The second mounting hole is sleeved on the outer ring of the second slewing support 8. The outer ring of the second slewing support 8 is rotatably arranged on the inner ring.

[0083] It is understood that the provision of the second slewing support 8 enables the boom 2 to rotate 360° relative to the chassis 3, thereby adjusting the posture and direction of the boom 2. When the special operation vehicle is in motion, the outrigger support assembly 5 can be driven to lift the chassis 3 off the ground, enabling the special operation vehicle to traverse obstacles in its direction of travel. When the special operation vehicle is in operation, the ability of the boom 2 to rotate 360° relative to the chassis 3 enables the boom 2 to rotate, expanding its operating range.

[0084] Specifically, the second rotary support 8 can be a turntable, the inner ring of the turntable fixes the boom 2, the mounting hole of the walking chassis 3 is sleeved with the outer ring of the turntable, and the rotation of the outer ring relative to the inner ring realizes the rotation of the boom 2 relative to the walking chassis 3.

[0085] like Figure 1 and Figure 2 As shown, the special operation vehicle of this embodiment further includes: a luffing mechanism 9.

[0086] The luffing mechanism 9 is connected to the boom 2 to adjust the elevation angle of the boom 2 relative to the traveling chassis 3 .

[0087] It is understandable that the luffing mechanism 9 includes a luffing cylinder and an articulated support mechanism, and the articulated support mechanism is driven by the luffing cylinder to further drive the change of the pitch angle of the boom 2.

[0088] In this embodiment, the boom 2 is flexibly adjusted in three dimensions by providing the luffing mechanism 9 , thereby ensuring the working stability of the boom 2 .

[0089] like Figure 1 and Figure 2 As shown, the special operation vehicle of this embodiment further includes: a platform crane 10.

[0090] The platform crane 10 includes a platform support 101 and a hook 102 .

[0091] The platform support 101 is installed on the working platform 1 , and the hook 102 is installed on the platform support 101 in a liftable manner.

[0092] It is understood that workers may need to replace parts or use different tools while performing on-site operations on the work platform 1. The platform crane 10 can provide on-site material lifting services for workers on the work platform 1. The platform support 101 is connected to the work platform 1, and the hook 102 can move vertically relative to the platform support 101 to install materials on the ground and transfer the materials to the work platform 1 as the hook 102 rises.

[0093] Specifically, the platform crane 10 may use an independent battery installed on the platform bracket 101 , or may be connected to a hydraulic power device or an electric power device on the traveling chassis 3 through a pipeline.

[0094] This embodiment integrates aerial work and material lifting by installing a platform crane 10 on the work platform 1, meeting both the needs of indoor and outdoor aerial manned work and material lifting.
