Description

Technical Field

[0001] This utility model belongs to the field of special equipment technology, specifically relating to a police aerial work platform. Background Technology

[0002] At large gatherings, such as concerts and sporting events, where there is a large flow of people, various security measures are implemented to prevent chaos, including high-level guard duty.

[0003] High-level guard duty is a special type of guard duty, referring to guarding positions at elevated or important locations. These elevated positions generally offer a wider field of vision, facilitating the timely detection of anomalies or monitoring. During large-scale events or emergencies, high-level guard duty can provide commanders with crucial on-site information, aiding decision-makers in making accurate judgments.

[0004] Currently, in practical applications, security forces lack a mobile, high-level observation post. Utility Model Content

[0005] This utility model provides a police aerial work platform to solve the technical problem in the prior art of security forces lacking high-level observation posts that can be moved to suit different scenarios. This utility model includes: a vehicle body; The lifting assembly includes: The first support rod is mounted on the vehicle body; A drive cylinder is located inside the first support rod, with the telescopic rod end of the drive cylinder extending out of the first support rod; The second support rod is sleeved on the outside of the first support rod, and the end of the telescopic rod is connected to the second support rod; The third support rod is sleeved on the outside of the second support rod, and the third support rod and the first support rod are connected by the first sliding assembly; The fourth support rod is sleeved on the outside of the third support rod, and the fourth support rod and the second support rod are connected by a second sliding assembly; The lifting platform is connected to the outside of the fourth support rod.

[0006] This utility model utilizes a lifting component to combine a lifting platform with a vehicle body, providing a platform that can both move and rise, meeting the needs of high-level observation posts used in different scenarios.

[0007] Furthermore: the first support rod, the second support rod, the third support rod, and the fourth support rod are all I-beams composed of pairs; The first support rod has a first roller on its upper end facing the second support rod; The second support rod has a second lower roller at its lower end facing the first support rod, and a second upper roller at its upper end facing the third support rod. The third support rod has a third lower roller at its lower end on the side facing the second support rod, and a third upper roller at its upper end on the side facing the fourth support rod. The fourth support rod is provided with a fourth roller at its lower end on the side facing the third support rod. The advantages of this step are: the lifting assembly composed of I-beams has high structural strength, low processing difficulty, and good reliability; and the shape of the I-beams themselves can be used as a limiting groove for the movement of multiple rollers.

[0008] Further: The first sliding component includes: The first fixed end A is located on the side of the first support rod; The first fixed pulley is located on the side of the second support rod and above the first fixed end A on the same side. The first fixed end B is located on the side of the third support rod and below the first fixed end A on the same side. The first traction rope has its two ends connected to the first fixed end A and the first fixed end B respectively, and is wound around the top of the first fixed pulley; The second sliding component includes: The second fixed end A is located on the side of the second support rod and above the first fixed pulley; The second fixed pulley is located on the side of the third support rod and above the second fixed end A on the same side. The second fixed end B is located on the side of the fourth support rod and below the second fixed end A on the same side. The second traction rope is connected at both ends to the second fixed end A and the second fixed end B respectively, and is wound around the top of the second fixed pulley. The beneficial effect of this step is that the linkage between the third support rod and the fourth support rod is realized through the first sliding component and the second sliding component.

[0009] Furthermore: the lifting platform includes: Foot platform; A guardrail is installed above the foot platform; The storage platform, located on the opposite side of the guardrail, offers the following advantages: the foot platform provides a standing platform for security personnel, the guardrail provides protection, and the storage platform can be used to place or install security equipment.

[0010] Furthermore, the guardrail is equipped with an electric control console and at least one storage frame. The advantages of this step are: the electric control console allows the lifting vehicle to move and rise; the storage frame is used to store water cups, sun umbrellas, etc.

[0011] Furthermore, the guardrail is equipped with double-leaf protective doors, which has the beneficial effect of forming a closed-loop protective structure.

[0012] Furthermore: the storage platform is surrounded by warning lights, and the front of the vehicle is equipped with a headlight. The beneficial effects of this step are: the warning lights can deter potential criminals and eliminate hidden dangers, and the headlights can serve as illumination and guidance.

[0014] Furthermore, the lifting assembly and the vehicle body are at an angle of 85° to 90°. The beneficial effect of this step is to keep the center of gravity in the middle of the vehicle body and maintain stability.

[0015] The beneficial effects of this utility model are: 1. Through the structure of the lifting components and the vehicle body, a mobile high-level guard platform is provided, which can be used in different occasions according to needs, making it more convenient and flexible; 2. The lifting assembly is composed of multiple I-beams, which can achieve a shorter total length when retracted and meet the needs of high-level guard duty when extended. The I-beams themselves have high structural strength, are sturdy and durable, and the grooves on both sides of the web of the I-beams can be used as limit grooves, eliminating the need for additional limit grooves, thus reducing costs and processing difficulty.
