[0002] Aerial work platforms are widely used in equipment installation, maintenance, and high-altitude construction. As they are manned equipment, their safety is a major concern for customers, and overloading is one of the major causes of safety accidents.

[0003] A Chinese patent with publication number CN107601383A discloses an aerial work platform vehicle, which includes a lifting arm, a working platform, and a weighing device. The lifting arm is connected to the working platform to lift and support the working platform, and the weighing device is located at the connection between the lifting arm and the working platform to weigh the working platform.

[0004] Regarding the aforementioned technologies, it has been found that existing aerial work platforms require protective structures for safety purposes. However, most existing protective structures are simple steel frame structures with poor protective effects, posing safety hazards when personnel operate the platform. Furthermore, the fixed space of the work platform restricts operation during use, affecting the operator's flexibility. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a device to prevent personnel from being crushed in an aerial work platform vehicle.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The bent baffle tube is evenly fixed on the main frame from top to bottom, and the positioning baffle is fixedly installed on the bent baffle tube.

[0009] As a preferred embodiment, several auxiliary pipes supporting the base plate are installed between the main frame and the lowest bending stop pipe, and the two ends of the auxiliary pipes are fixedly connected to the main frame and the bending stop pipe respectively.

[0010] As a preferred embodiment, the moving frame includes a left frame and a right frame, the right frame is fixedly installed on the right side of the left frame, and a mating port corresponding to the inlet and outlet is provided between the left frame and the right frame.

[0011] As a preferred embodiment, the left and right frames are provided with sliding rods on the side facing the fixed frame portion, which slide in conjunction with the bent stop tube, and the sliding rods are fixedly connected to both the left and right frames.

[0012] As a preferred embodiment, the cage baffle includes a main frame and diagonal braces fixed to the main frame. The lower ends of both the main frame and the diagonal braces are provided with connecting locks that are fixed to the bent baffle tubes.

[0013] As a preferred embodiment, the connecting lock frame includes a first clamping plate and a second clamping plate, the head of the second clamping plate is rotatably connected to the first clamping plate, and a connecting bending plate is fixedly installed at the lower end of both the first clamping plate and the second clamping plate, and a connecting groove is provided on the connecting bending plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This application designs the equipment protective frame as a structure in which a fixed frame part and a movable frame part cooperate. When easy to use, the position of the movable frame part on the fixed frame part can be controlled by an electric cylinder. This allows for easy adjustment of the position of the movable frame part to change the overall protection mode of the equipment protective frame during use. When the movable frame part moves outward, it can drive the extension platform to extend synchronously. Personnel on the bottom shell of the equipment can stand on the extension platform to free up the bottom shell of the equipment, thus ensuring better access for items to be placed or removed from the bottom shell of the equipment. Moreover, the extension platform increases the working space for operators, providing more operating space and facilitating high-altitude fixed-point operations. At the same time, by installing a man-cage guard on the fixed frame part, the man-cage guard can be quickly installed by connecting a locking frame, thereby increasing the safety of personnel during operation.
