[0017] The following is a further detailed description through specific implementation methods:

[0018] like Figures 1 to 4 As shown:

[0019] A pneumatic lifting guardrail device includes a support module, a plurality of drive modules, a guide module and a guardrail body 4. The support module is used to support and install the drive module and the guide module. The drive module is installed on the top of the support module. The support module is composed of a first gantry 1 and a second gantry 9, and the drive module is fixedly installed between the two gantries; the guide module is two slide rails 2 and a slider 3 adapted to the slide rails 2. The slide rails 2 are fixedly installed on the inner sides of the two columns of the first gantry 1, and the two sliders 3 are fixedly installed on both sides of the bottom of the guardrail body 4. The two sliders 3 are respectively slidably installed on the slide rails 2, so that the guardrail body 4 is installed between the two slide rails 2, that is, located at the first gantry 1. The slider 3 has a cylindrical structure, so that the slider 3 can slide on the slide rail 2 while the slider 3 can rotate relative to the slide rail 2, and the guardrail body 4 can be stored between the two gantries when it rises.

[0020] The driving module includes a linear cylinder 7, a connecting rod 5 and a connecting shaft 6. The two ends of the linear cylinder 7 are respectively fixedly installed on the top of the first gantry 1 and the second gantry 9, so that the linear cylinder 7 spans between the two gantries. The slide seat of the linear cylinder 7 is rotatably connected to one end of the connecting rod 5 through the connecting shaft 6. The other end of the connecting rod 5 is hinged to the guardrail body 4. A corresponding empty groove is provided at the guardrail body 4 to avoid interference between the guardrail body 4 and the connecting rod 5, so that the connecting rod 5 can smoothly drive the guardrail body 4 to move to the horizontal direction, so that the slide seat of the linear cylinder 7 can drive the top of the guardrail body 4 to move together through the connecting rod 5 while moving.

[0021] A limit baffle 8 is provided at the slide rail 2, so that when the guardrail body 4 is driven in a vertical state, the guardrail body 4 can be against the limit baffle 8, and the limit baffle 8 can support the guardrail body 4. Under the coordinated action of the sliding seat of the linear cylinder 7, the guardrail body 4 is clamped between the connecting rod 5 and the limit baffle 8, so that the placement of the guardrail body 4 is more stable.

[0022] The specific implementation process is as follows:

[0023] When using the up and down pneumatic lifting guardrail device, install the device at the corresponding equipment or place; when the device is started, the slide seat of the linear cylinder 7 drives the connecting rod 5 to move together through the connection rotation, and the connecting rod 5 drives the upper end of the guardrail body 4 to move, so that the guardrail body 4 rises between the two slide rails 2 while gradually moving horizontally until the guardrail body 4 is relatively horizontally placed at the bottom of the linear cylinder 7, and the first gantry 1 can be opened, so that people or objects can pass through the first gantry 1.

[0024] The up and down pneumatic lifting guardrail device installs the guardrail body 4 through the slide rail 2 installed at the first gantry 1, and drives the guardrail body 4 up and down in a pneumatic manner through the linear cylinder 7 installed between the first gantry 1 and the second gantry 9, so that the guardrail body 4 can be stored between the two gantries when it rises, reducing the space occupied in the height direction, making it easy for the device to be installed and used in a space with limited height, and convenient for users to use.
