Abstract
Claims
1. A lifting platform, characterized in that, include: platform; A lifting mechanism is provided at the bottom of the platform, and the lifting mechanism is used to drive the platform to lift. A fence gate assembly includes a gate frame and a fence gate. The gate frame surrounds the side of the platform opposite to the lifting mechanism, and the side of the gate frame has an opening. The fence gate is movably connected to the gate frame from the opening, and the fence gate includes an open state and a closed state. A locking device, including a locking element, is movably disposed on the fence gate assembly; When the fence gate is closed and the locking member is in the first position, the gate frame and the fence gate are locked to restrict the movement of the gate frame relative to the fence gate; when the locking member is in the second position, the gate frame and the fence gate are unlocked to allow the gate frame to move relative to the fence gate.
2. The lift platform of claim 1, wherein, The first position is higher than the second position; The locking device further includes: A push rod, one end of which is connected to the bottom of the locking member, and the other end extends downward and protrudes from the bottom of the platform; A top frame is positioned on the lifting mechanism corresponding to the position of the top rod. The top frame is used to abut against the other end of the top rod when the platform moves downward to a set position, thereby driving the top rod and the locking member to move upward.
3. The lift platform of claim 1, wherein, The locking element includes a locking groove facing the fence gate; When the locking member is in the first position, the door frame and the fence gate are engaged and locked by the locking groove; When the locking member is in the second position, the locking groove and the fence gate assembly are spaced apart along the height direction to avoid the fence gate assembly.
4. The lift platform of claim 3, wherein, The locking groove includes a first sidewall and a second sidewall disposed opposite to each other, wherein the length of the first sidewall along the height direction is less than the length of the second sidewall along the height direction. When the locking member is in the first position, the interference between the first sidewall and the fence gate assembly is less than the interference between the second sidewall and the fence gate assembly; When the locking member is in the second position, the first sidewall is spaced apart from the fence gate assembly along the height direction to avoid the fence gate assembly, and the bottom of the second sidewall is attached to the top of the fence gate assembly.
5. The lift platform of claim 2, wherein, The top rod passes through the door frame along the height direction, and the top rod includes an extension portion that extends downward and protrudes from the bottom of the platform; The top frame is positioned on the lifting mechanism corresponding to the position of the extension. The top frame is used to abut against the extension when the platform moves downward to a set position, thereby driving the top rod and the locking member to move upward.
6. The lift platform of claim 5, wherein, The set position is the lowest position of the platform within its movable range in the height direction.
7. The lift platform of claim 5, wherein, The locking device further includes an elastic element, which is sleeved on the extension. When the platform moves to the set position, the top frame abuts against the elastic element, causing the elastic element to contract towards the platform, so that the elastic element provides an elastic restoring force to the top rod.
8. The lift platform of claim 7, wherein, The locking device further includes a limiting part, one end of the elastic member abuts against the platform, and the other end is connected to the limiting part; when the platform moves to the set position, the top frame abuts against the limiting part, and the limiting part drives the elastic member to retract towards the platform.
9. The lift platform of claim 2, wherein, The top rod is a cylindrical rod, and a square hollow structure is provided inside the door frame along the height direction. The top rod passes through the hollow structure, and the top end of the top rod extends out of the hollow structure and connects with the locking member.
10. An aircraft fueler characterized by, It includes a mobile device and a lifting platform as described in any one of claims 1-9, wherein the bottom of the lifting mechanism is connected to the mobile device, and the mobile device is used to move the lifting platform on the ground.
11. The aircraft refueling vehicle according to claim 10, characterized in that, Includes a reset sensor, which is electrically connected to the moving device, and the reset sensor is fixed to the bottom of the lifting mechanism; When the lifting mechanism moves the platform to the lowest position, the reset sensor outputs a first signal, and the moving device is used to switch to the movable mode in response to the first signal. When the lifting mechanism moves the platform away from the lowest position, the reset sensor outputs a second signal, and the moving device switches to a non-movable mode in response to the second signal.
