Description

Technical Field

[0001] The utility model relates to the field of aerial work platforms, in particular to a scissor-type aerial work platform with a safety protection structure. Background Art

[0002] In the field of aerial work, scissor lifts are widely used in various construction, maintenance and inspection work due to their flexibility and stability. However, under certain conditions, such as curved and inclined sites, traditional scissor lifts face significant technical challenges. These challenges mainly stem from the platform's reliance on level ground and its limitations in mobility and stability.

[0003] Scissor lifts are designed to operate on level ground for stability and safety. When used on uneven or sloping ground, the platform may tilt, increasing the risk of operators falling and compromising the structural integrity of the equipment. The use of blocks or other temporary leveling methods can partially solve the tilt problem, but this method limits the platform's mobility. Once the blocks are in place, the platform cannot be moved easily, which reduces work efficiency, especially in operations that require frequent position adjustments. Although crawler equipment provides better traction and stability on uneven terrain, they also have difficulty maintaining a stable position on curved and sloping sites, especially in situations that require precise positioning and high-precision operations. Utility Model Content

[0004] The main purpose of the utility model is to provide a scissor-type aerial work platform with a safety protection structure, which solves the problem that when used on an uneven or inclined ground, the platform may tilt, increasing the risk of an operator falling.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a scissor-type aerial work platform with a safety protection structure, the protection structure is: the driving crawler is connected to the base, the hinged seat in the middle of the base is hinged to the middle of the balance seat, an automatic telescopic rod is provided between the end of the base and the end of the balance seat, the telescopic end of the automatic telescopic rod is hinged to the end of the base, the cylinder body of the automatic telescopic rod is hinged to the end of the balance seat, an inclination sensor is provided on the balance seat, a winch is also provided on the base, a fixed anchor point is provided at the end of the maintenance channel, and the fixed anchor point is connected to the winch through a rope.

[0006] In a preferred embodiment, the two protection structures are connected via a connecting frame, both ends of the connecting frame are respectively connected to the balance seats of the protection structures, and at least one winch is provided on the connecting frame.

[0007] In the preferred embodiment, an inclination sensor is also provided on the balancing seat, and the inclination sensor is electrically connected to the controller, and the controller is connected to the automatic telescopic rod.

[0008] In the preferred embodiment, a plurality of adjustment seats are provided around the circumference of the scissor lift, and the adjustment seats abut against the upper surface of the balance seat.

[0009] In a preferred embodiment, the scissor lift is fixed to the upper surface of the balance seat by a fixed rod.

[0010] In the preferred embodiment, a stabilizing bar is provided on the top working platform of the scissor lift, and the stabilizing bar is used to be connected to the side wall of the maintenance passage.

[0011] The utility model provides a scissor-type aerial work platform with a safety protection structure. Through the linkage of the automatic telescopic rod and the inclination sensor, the platform can automatically adjust its posture to maintain stability on inclined or uneven ground, significantly reducing the risk of overturning caused by uneven ground. The added stabilizing rod and fixed anchor point provide additional longitudinal and lateral support through the cooperation of ropes and winches, effectively preventing the aerial work platform from shaking and deflecting during operation, and ensuring the personal safety of operators. The design of the drive track allows the platform to move in complex terrain without limiting mobility like the traditional pad leveling method, thereby improving mobility and work efficiency at the construction site. The combination of the inclination sensor and the controller realizes automated balance adjustment, reduces the need for manual intervention, and enables the platform to adapt to various ground conditions more intelligently. It greatly improves the safety and efficiency of operations in complex and harsh environments, bringing significant progress to the aerial work industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figures 1 to 8 As shown, a scissor-type aerial work platform with a safety protection structure, the protection structure is: the driving crawler 8 is connected to the base 9, the hinged seat in the middle of the base 9 is hinged to the middle of the balance seat 10, an automatic telescopic rod 11 is provided between the end of the base 9 and the end of the balance seat 10, the telescopic end of the automatic telescopic rod 11 is hinged to the end of the base 9, the cylinder of the automatic telescopic rod 11 is hinged to the end of the balance seat 10, an inclination sensor 12 is provided on the balance seat 10, a winch 7 is also provided on the base 9, a fixed anchor point 1 is provided at the end of the maintenance channel 3, and the fixed anchor point 1 is connected to the winch 7 through a rope 2. The driving crawler 8 provides good traction and stability of the platform on different terrains, especially suitable for uneven or soft surfaces.

[0023] The hinged connection between the base 9 and the balancing seat 10 allows the balancing seat 10 to be adjusted in angle relative to the base 9 to adapt to the inclined or undulating ground, thereby ensuring the levelness and stability of the entire platform.

[0024] The automatic telescopic rod 11 connects the base 9 and the balance seat 10, and can automatically adjust the length according to the ground conditions, assisting the balance seat to maintain levelness, while enhancing the stability of the overall structure.

[0025] The inclination sensor 12 is installed on the balance seat 10 and is used to monitor the inclination angle of the platform in real time. The data is fed back to the control system to automatically adjust the automatic telescopic rod 11 to maintain the balance of the platform 10.

[0026] The winch 7 is connected to the rope 2 of the fixed anchor point 1: The winch is installed on the base and connected to the fixed anchor point 1 by a rope, which can provide additional stability and positioning capabilities when necessary, especially in high or strong wind conditions, or when the platform is at a high altitude.

[0027] In the preferred embodiment, the two protection structures are connected by a connecting frame 6, and the two ends of the connecting frame 6 are respectively connected to the balance seat 10 of the protection structure, and at least one winch 7 is provided on the connecting frame 6. The two ends of the connecting frame 6 are respectively connected to the balance seats 10 of the two protection structures, ensuring a firm connection between the two parts and avoiding separation or looseness during use. The existence of the connecting frame 6 strengthens the structural stability of the entire system, can better resist lateral forces, and protect the safety of operators.

[0028] In the preferred embodiment, the balancing seat 10 is also provided with an inclination sensor 12, which is electrically connected to the controller, and the control is connected to the automatic telescopic rod 11. The inclination sensor 12 continuously monitors the inclination angle of the balancing seat 10, and can quickly detect the inclination caused by uneven ground or external force. When it is detected that the inclination exceeds the preset safety range, the inclination sensor 12 will send a signal to the controller, and the controller will instruct the automatic telescopic rod 11 to perform corresponding actions according to the received data to restore the horizontal state of the platform. © The controller continuously adjusts the extension degree of the automatic telescopic rod 11 by receiving real-time data from the inclination sensor 12, forming a dynamic balance adjustment cycle to ensure that the platform remains as horizontal as possible at any time.

[0029] In the preferred embodiment, a plurality of adjustment seats 401 are provided around the scissor lift 4, and the adjustment seats 401 are against the upper surface of the balance seat 10. The adjustment seats 401 help to evenly distribute the weight of the scissor lift 4 to the balance seat 10, ensuring that during the lifting process, the weight of the platform will not be concentrated at a certain point, but evenly dispersed, reducing the risk of local overload.

[0030] The adjustment seat 401 increases the contact area between the scissor lift 4 and the balance seat 10, provides greater friction and support force, and prevents sliding or instability during operation.

[0031] In the preferred embodiment, the scissor lift 4 is fixed to the upper surface of the balance seat 10 by a fixed rod 13. The fixed rod 13 serves as a direct physical connection between the scissor lift 4 and the balance seat 10, which enhances the structural rigidity between the two, reduces shaking and vibration during the lifting process, and ensures the stability of the platform. Through the connection of the fixed rod 13, the position of the scissor lift 4 on the balance seat 10 is locked, preventing position deviation caused by external force during movement or operation, and improving the accuracy and reliability of operation.

[0032] In the preferred embodiment, a stabilizing bar 5 is provided on the top working platform of the scissor lift 4, and the stabilizing bar 5 is used to connect with the side wall of the maintenance passage 3. The stabilizing bar 5 provides additional lateral stability for the scissor lift 4 by connecting with the side wall of the maintenance passage 3. In a narrow or complex maintenance passage 3, the use of the stabilizing bar 5 enables the scissor lift 4 to operate more safely and efficiently, and maintain good operating performance even in a limited space.

[0033] 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.
