The supporting member 122 can rotate around one end connected to the barrel body of the inner barrel 12, the supporting member 122 can rotate to be close to the barrel body of the inner barrel 12, the driving component 13 is provided with an electromagnetic member at a position close to the inner barrel 12, the electromagnetic member generates magnetism when being electrified, the electromagnetic member is close to the barrel body of the inner barrel 12 to enable the inner barrel 12 to have magnetism, so that the supporting member 122 is magnetically attracted to the barrel body of the inner barrel 12, the supporting member 122 is prevented from blocking the inner barrel 12 to descend when the inner barrel 12 descends, the supporting member 122 which is not received is prevented from being broken when the inner barrel 12 descends, the supporting member 122 plays a role of protecting the supporting member 122, meanwhile, the electromagnetic member can enable the supporting member 122 to be magnetically attracted to the barrel body of the inner barrel 12, when the electromagnetic member is powered off, the supporting member 122 can be separated from the barrel body of the inner barrel 12, and can rotate to fall to be abutted to the groove on the fixing member 112, the driving component 13 falls to be separated from the inner barrel 12 to be in contact with the inner barrel 12, so that the acting force generated by the collision of the lifting pile 1 when the vehicle can be transmitted to the ground through the supporting member 122, reduce the effort that inner tube 12 received, simultaneously, drive assembly 13 drops, can avoid inner tube 12 to conduct the effort to drive assembly 13 on, prevent that drive assembly 13 from receiving the damage, improve drive assembly 13's life, it is more convenient to the maintenance of lift stake 1.

The control system 14 can control the driving assembly 13, so that the driving assembly 13 can be controlled, the control system 14 can control the driving assembly 13 through an electric signal, meanwhile, the control system 14 controls the extending or retracting of the clamping member 111 through the electric signal, the driving assembly 13 is provided with an electromagnetic member, the control system 14 controls the electromagnetic member to be powered on or off, and controls the magnetism of the electromagnetic member, so that the supporting member 122 can be magnetically attracted on the barrel body of the inner barrel 12, the supporting member 122 is prevented from obstructing the descending of the inner barrel 12, meanwhile, the magnetism of the electromagnetic member is controlled, the falling of the supporting member 122 can be controlled, and the middle-level bearing capacity of the inner barrel 12 is improved.

The speed detector is arranged outside the lifting pile 1, the approaching speed of an approaching vehicle can be detected, when the approaching vehicle keeps or accelerates the approaching speed of the lifting pile 1, the control system 14 controls the clamping piece 111 to extend out and abut against the groove position 121, the electromagnetic piece is powered off, the supporting piece 122 falls down, the driving component 13 is separated from the inner cylinder 12 to deal with the vehicle with the current higher speed, and the collided vehicle is intercepted.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit of the present invention are intended to be included within the scope of the present invention.
