Now its meaning has been expanded to describe various facilities for managing pedestrian traffic, protecting key infrastructure, setting perimeters, and distinguishing roads. At present, lifting bollards can generally only rise or fall slowly. When there are vehicles or pedestrians above the lifting bollards, the slowly rising lifting bollards may cause danger; when encountering an unexpected event and needing to raise the lifting bollards urgently, the lifting bollards cannot be raised in time to effectively intercept the vehicles; when there is a sudden power outage, the lifting bollards cannot continue to rise.

[0017] The first embodiment of the present application is:

[0018] See also Figure 1-Figure 2 , Figure 1 It is a structural schematic diagram of the utility model. Figure 2 It is an internal cross-sectional view of the utility model. The one-piece lifting column of the present embodiment comprises an outer cylinder 101, a lifting column body 102, an inner cylinder 103 and a protective assembly. The protective assembly comprises a retaining ring 104, a drainage component and a heating component. The drainage component comprises a drainage box 105 and a guide plate 106. The heating component comprises a thermally conductive silicone cylinder 107 and a heating block 108. The above-mentioned solution solves the problem that the one-piece pneumatic lifting column has poor protection and fails under the influence of rain or low temperature, thereby affecting the use of the lifting column. It can be understood that the above-mentioned solution can be used in scenarios where the lifting column is used.

[0019] According to this specific embodiment, the lifting column body 102 is fixedly connected to the outer cylinder 101 and is located in the outer cylinder 101, the inner cylinder 103 is fixedly connected to the lifting column body 102 and is located on one side of the lifting column body 102, the retaining ring 104 is fixedly connected to the outer cylinder 101 and is located on the side of the outer cylinder 101 close to the inner cylinder 103, the drainage member is arranged on the side of the outer cylinder 101 close to the retaining ring 104, the heating member is fixedly connected to the lifting column body 102 and is located on one side of the lifting column body 102, the lifting column body 102 operates to drive the inner cylinder 103 to push out of the outer cylinder 101 or retract to the outer cylinder 101, so as to temporarily block the passage and prevent vehicles from passing through, thereby maintaining traffic order, and the protection component is provided for the lifting column body 1 02 is protected to prevent external factors such as rain and low temperature from affecting the normal use of the lifting column body 102. Specifically, rainwater enters the outer cylinder 101 from the contact surface between the inner cylinder 103 and the outer cylinder 101, and is guided and discharged from the outer cylinder 101 by the drainage component, thereby preventing the rainwater from entering and causing the lifting column body 102 to malfunction. When the temperature is low in winter, the heating component operates to heat the hydraulic seat of the lifting column body 102 to keep the hydraulic oil viscous, thereby ensuring that the lifting column body 102 can operate normally. The retaining ring 104 is provided to filter debris in the rainwater to prevent debris from entering the outer cylinder 101, causing the inner cylinder 103 to be stuck when it is ejected or retracted, thereby solving the problem that the integrated pneumatic lifting column has poor protection and malfunctions under the influence of rain or low temperature, thereby affecting the use of the lifting column.

[0020] The guide plate 106 is fixedly connected to the outer tube 101 and is located near the inner tube 103. The drainage box 105 is arranged at the bottom of the guide plate 106. The guide plate 106 is used to guide the rainwater flowing into the inner tube 103 into the drainage box 105, and then discharge the inner tube 103 through the drainage box 105, so as to provide waterproof protection for the lifting column body 102 in the inner tube 103, thereby preventing the lifting column body 102 from malfunctioning due to the infiltration of rainwater.

[0021] Secondly, the thermally conductive silicone tube 107 is fixedly connected to the lifting column body 102 and is located on one side of the lifting column body 102. The heating block 108 is arranged on the side of the thermally conductive silicone tube 107 away from the lifting column body 102. The heating block 108 is a resistive heating block, which is a common technology on the market. It is used to heat the hydraulic seat of the lifting column body 102 to ensure that the lifting column body 102 can operate normally. The thermally conductive silicone tube 107 is set to conduct heat to the hydraulic seat, so that the heat of the heating block 108 can act evenly on the hydraulic seat.

[0022] When the protection component is in use, the retaining ring 104 is used to filter debris in the rainwater to prevent the debris from entering the outer cylinder 101, causing the inner cylinder 103 to be stuck when it is pushed out or retracted. After the rainwater enters the inner cylinder 103, it is introduced into the drainage box 105 through the guide plate 106, and then discharged from the inner cylinder 103 through the drainage box 105, so as to provide waterproof protection for the lifting column body 102 in the inner cylinder 103, thereby preventing the lifting column body 102 from malfunctioning due to rainwater infiltration. When the temperature is low in winter, the heating block 108 is powered on to generate heat, and the thermal conductive silicone tube 107 then transfers the heat to the hydraulic seat of the lifting column body 102, so that the hydraulic oil remains viscous, ensuring that the lifting column body 102 can operate normally.

[0023] The second embodiment of the present application is:

[0024] Based on the first embodiment, please refer to Figure 3 , Figure 3 20 is an internal cross-sectional view of the utility model. The one-piece lifting column of this embodiment further includes a warning component, and the warning component includes a mounting strip 201 and a flashing light strip 202 .

[0025] According to this specific embodiment, the warning component is arranged on one side of the inner tube 103. The warning component is used to warn the driver and pedestrians when the lifting column is used at night, so as to avoid traffic accidents caused by the driver failing to see the lifting column clearly when the lifting column is used at night.

[0026] The mounting bar 201 is fixedly connected to the inner tube 103 and is located at one side of the inner tube 103. The flashing light bar 202 is detachably connected to the mounting bar 201 and is located at a side of the mounting bar 201 away from the inner tube 103. The mounting bar 201 provides mounting conditions for the flashing light bar 202. The flashing light bar 202 is used to flash to remind drivers and pedestrians, so as to avoid traffic accidents caused by the driver failing to see the lifting column clearly when the lifting column is used at night.

[0027] When the warning component is in use, the flashing light bar 202 is installed on the installation bar 201. At night, the flashing light bar 202 is started. When the lifting column body 102 pushes out of the inner tube 103, the flashing light bar 202 flashes to remind the driver and pedestrians, so as to avoid traffic accidents caused by the driver failing to see the lifting column clearly when the lifting column is used at night.
