DETAILED DESCRIPTION

[0022] like Figures 1 to 6 As shown, a spider-type aerial work platform is shown, wherein a base 4 is arranged on a crawler wheel 3, and the base 4 is connected to a load-bearing arm 12 through a swivel seat 14, and an end of the load-bearing arm 12 is hinged to one end of a telescopic arm 11, and the other end of the telescopic arm 11 is hinged to an adjusting arm 10 of a parallel four-bar structure, and the other end of the adjusting arm 10 is hinged to a connecting plate 8, and the connecting plate 8 is connected to a work platform 7, and a fourth oil cylinder 1001 is arranged between the telescopic arm 11 and the adjusting arm 10, and a second oil cylinder 9 is arranged between the adjusting arm 10 and the connecting plate 8, and the second oil cylinder 9 and the fourth oil cylinder 1001 are used for adjusting the balance of the work platform 7.

[0023] The base 4 is equipped with track wheels 3 to ensure the stability of movement in complex terrain. The base 3 is connected to the carrying arm 12 through a swivel seat 14 to form a rotation center for omnidirectional operation.

[0024] The end of the carrying arm 12 is hinged to the telescopic arm 11, which is in turn connected to the adjusting arm 10 of the parallel four-bar structure. This design allows the working platform 7 to be telescopic in the vertical direction and tilted in the horizontal direction.

[0025] A fourth oil cylinder 1001 is provided between the telescopic arm 11 and the adjusting arm 10, and a second oil cylinder 9 is provided between the adjusting arm 10 and the connecting plate 8. The two oil cylinders work together to ensure that the working platform 7 can remain balanced and stable when operating at multiple angles.

[0026] The connecting plate 8 serves as a bridge between the working platform 7 and the adjusting arm 10, and ensures the free movement and positioning of the platform by means of articulation.

[0027] The support leg 2 has a storage function and can be folded up when not in use to reduce the floor space. The independent telescopic and rotation functions enable the support legs to adapt to different terrains and operating requirements, significantly improving the adaptability and stability of the platform.

[0028] In the preferred embodiment, the adjusting arm 10 includes an upper connecting rod 1003 and a lower connecting rod 1004, and the two ends of the upper connecting rod 1003 and the lower connecting rod 1004 are respectively hinged to the end of the telescopic arm 11 and the connecting rod seat 1002 to form a parallel four-bar mechanism. One end of the fourth oil cylinder 1001 is connected to the telescopic arm 11, and the other end is hinged to the middle position of the upper connecting rod 1003. The connecting rod seat 1002 is hinged to one end of the connecting plate 8, and one end of the second oil cylinder 9 is hinged to the middle position of the connecting rod 1003, and the other end is hinged to the connecting plate 8.

[0029] The adjusting arm 10 is designed as a parallelogram structure consisting of an upper connecting rod 1003 and a lower connecting rod 1004 . The design purpose of this structure is to achieve precise balance adjustment and angle adjustment of the working platform 7 .

[0030] The ends of the upper connecting rod 1003 and the lower connecting rod 1004 are respectively hinged to the telescopic arm 11 and the connecting rod seat 1002 to form a stable parallelogram structure. Such a design allows the working platform to move and tilt smoothly in multiple directions.

[0031] One end of the fourth oil cylinder 1001 is connected to the telescopic arm 11, and the other end is hinged to the middle of the upper connecting rod 1003. When the fourth oil cylinder 1001 is extended or retracted, it will change the angle between the upper connecting rod 1003 and the telescopic arm 11, thereby affecting the state of the entire parallelogram structure, and realizing the vertical balance adjustment of the working platform 7.

[0032] One end of the second oil cylinder 9 is hinged to the middle position of the upper connecting rod 1003, and the other end is hinged to the connecting plate 8. The telescopic action of the second oil cylinder 9 can adjust the position of the upper connecting rod 1003 relative to the connecting plate 8, thereby adjusting the horizontal inclination angle of the working platform 7.

[0033] Through the coordinated work of the second oil cylinder 9 and the fourth oil cylinder 1001, the utility model can achieve fine control of the balance and angle of the working platform 7. This not only allows the working platform to remain stable on uneven or inclined ground, but also can be adjusted to the optimal working angle according to actual working needs, greatly enhancing the safety and efficiency of aerial work.

[0034] In the preferred solution, an angle sensor is provided on the working platform 7, a control center 6 is provided on the base 4, the angle sensor is electrically connected to the control center 6, and the control center 6 is connected to the hydraulic control system on the base 4. The angle sensor monitors the tilt angle of the working platform 7 in real time and transmits the data to the control center 6. These sensors are usually high-precision and can detect slight angle changes to ensure the stability of the platform under any working conditions.

[0035] After receiving the data from the angle sensor, the control center 6 calculates the current tilt state of the working platform 7 through the built-in algorithm and determines whether adjustment is needed. If the platform deviates from the preset safe tilt range, the control center will send instructions to the hydraulic control system to adjust the telescopic state of the second cylinder 9 and the fourth cylinder 1001, thereby changing the tilt angle of the working platform to restore it to the safe range.

[0036] After receiving the command from the control center 6, the hydraulic control system accurately controls the extension and retraction of the second cylinder 9 and the fourth cylinder 1001, and adjusts the angle of the working platform 7 by changing the length of the cylinder to ensure that the platform remains stable and safe during the operation.

[0037] The spider aerial work platform has improved its safety and its adaptability in complex environments. Through automated adjustment, it reduces the need for manual intervention, improves operational efficiency, and reduces the risks faced by operators, providing a more reliable and efficient solution for aerial work.

[0038] In the preferred embodiment, support legs 2 are provided around the base 4, and the ends of the support legs 2 are longitudinally hinged to the support rotating seat 1, and the other end of the support rotating seat 1 is vertically hinged to the base 4. One end of the support rotating seat 1 is hinged to one end of the first oil cylinder 5, and the other end of the first oil cylinder 5 is hinged to the middle bending position of the support leg 2. The ends of the support legs 2 are longitudinally hinged to the support rotating seat 1, and the other end of the support rotating seat 1 is vertically hinged to the base 4. This design allows the support legs 2 to be both unfolded to increase the stability of the platform and folded up for easy movement and storage. The vertical hinge point between the support rotating seat 1 and the base 4 allows the support legs 2 to rotate in a vertical plane, realizing the conversion from unfolding to folding, which is convenient for rapid adjustment under different working conditions.

[0039] One end of the first oil cylinder 5 is hinged to the support rotating seat 1, and the other end is hinged to the middle bending position of the support leg 2. Through the telescopic action of the first oil cylinder 5, the lifting and lowering of the support leg 2, that is, the unfolding or storage process, can be controlled.

[0040] In addition to controlling the deployment and storage of the support legs 2, the first oil cylinder 5 can also adjust the height of the entire track wheel 3 and the base 4 through its telescopic action, which is crucial for adjusting the horizontal state of the platform when working on uneven ground.

[0041] In the preferred embodiment, the supporting end of the supporting leg 2 is also hinged with a supporting foot 201. Since the supporting foot 201 can automatically adjust its posture according to the ground conditions, it can more evenly distribute the weight of the working platform, avoiding instability caused by excessive force on a single point, thereby significantly improving the overall stability of the working platform.

[0042] In the preferred embodiment, the support rotating seat 1 is also provided with a pin hole 101, and the pin passes through the pin hole 101 of the support rotating seat 1 and the base 4 to fix the position of the support rotating seat 1 after the rotation angle. When the support leg 2 is adjusted to the desired position, the operator can insert the pin through the pin hole 101 on the support rotating seat 1 and the corresponding fixed point of the base 4 to form a physical lock. In this way, even if external force interference is encountered during the operation, the support rotating seat 1 can be maintained at the set angle to ensure the stability of the support leg 2 and the overall safety of the platform.

[0043] The combined use of the pin hole 101 and the latch not only simplifies the locking process of the support leg 2, but also greatly improves the stability of the work platform during aerial work and reduces the safety risks caused by accidental movement of the support leg.

[0044] In the preferred embodiment, one end of the third oil cylinder 13 is connected to the load-bearing arm 12, and the other end of the third oil cylinder 13 is hinged to the telescopic arm 11. One end of the third oil cylinder 13 is connected to the load-bearing arm 12, and the other end is hinged to the telescopic arm 11. This connection mode allows the third oil cylinder 13 to directly act on the telescopic arm 11 when extending and retracting, driving it to move up and down.

[0045] When the third oil cylinder 13 is extended, it pushes the telescopic arm 11 to move upward, thereby increasing the height of the working platform 7. Conversely, when the third oil cylinder 13 is retracted, the position of the telescopic arm 11 is lowered, so that the working platform 7 is lowered. This height adjustment mechanism provides great flexibility for aerial work, and the working height can be quickly adjusted according to actual working needs.

[0046] In the preferred embodiment, the lower end of the carrying arm 12 is connected to the worm gear 1401 of the swivel seat 14 , the worm gear 1401 is rotatably connected to the base 4 , the worm gear 1401 is meshed with the worm 1402 , and the worm 1402 is disposed on the base 4 .

[0047] The lower end of the carrying arm 12 is connected to the worm wheel 1401 on the swivel seat 14. As a key component of the rotary transmission, the worm wheel 1401 has a tooth shape that matches the helical surface of the worm 1402, and can transmit torque and achieve deceleration.

[0048] The worm 1402 is fixed on the base 4 and meshes with the worm wheel 1401. When the worm 1402 rotates, it drives the worm wheel 1401 to rotate, thereby driving the carrying arm 12 to rotate around the axis. The transmission ratio of the worm gear is usually large, which can achieve low-speed and high-torque output, which is suitable for the smooth rotation of the carrying arm.

[0049] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
