[0008] According to the above technical scheme, the refueling device also includes a No. 1 slide rail, a fuel tank door, a seesaw, a No. 2 clamping block, a door handle and an oil pipe. The No. 1 slide rail is fixedly installed on the top of the auxiliary fuel tank, the fuel tank door is slidably installed on the top of the auxiliary fuel tank, the seesaw is rotatably installed on the top of the auxiliary fuel tank, the No. 2 clamping block is fixedly installed on the bottom of the seesaw near one end of the fuel tank door, the door handle is fixedly installed on the top of the fuel tank door, and the oil pipe is fixedly installed on the back of the tank body. The lubricating oil is introduced into the telescopic refueling pipe through the auxiliary fuel tank, and the telescopic refueling pipe sends the lubricating oil into the main fuel tank, so that when the lubricating oil in the main fuel tank needs to be replenished, the auxiliary fuel tank can send the lubricating oil into the main fuel tank in time, so that the main fuel tank can continuously provide lubricating oil to the hook to prevent the main fuel tank from lacking lubricating oil and being unable to provide lubricating oil to the hook for lubrication, resulting in the hook being unable to work normally.

[0009] According to the above technical solution, one end of the No. 1 clamping block close to the No. 1 rack is set to an inclined surface, a No. 1 clamping slot is opened on one side of the No. 1 rack close to the No. 1 clamping block, a No. 2 clamping slot is opened on the top of the oil tank door, a No. 1 spring is arranged between the rocker and the auxiliary oil tank, and the bottom of the No. 2 clamping block is set to an inclined surface, so that when the lubricating oil in the main oil tank needs to be replenished, the auxiliary oil tank can deliver the lubricating oil into the main oil tank in time, so that the main oil tank can continuously provide lubricating oil to the hook, so as to prevent the lubricating oil in the main oil tank from being insufficient and unable to provide lubricating oil to the hook for lubrication, resulting in the hook being unable to work normally.

[0010] According to the above technical solution, the No. 1 rack is meshed with the No. 1 gear, a No. 2 spring is provided between the No. 1 block and the baffle, a tooth groove is provided on the circumferential surface of the end of the telescopic refueling pipe close to the main oil tank, and the No. 1 gear is meshed with the tooth groove, so that the hook can completely grab the ton bag during operation and can smoothly complete the grabbing action, so as to prevent the hook from being without lubrication of lubricating oil for a long time, resulting in serious wear and tear of some components of the hook during daily work and losing its original function, causing the hook to fail to grab and the grabbing process to be slow and not smooth during daily work.

[0011] According to the above technical scheme, the clamping device includes a No. 2 gear, a No. 3 gear, a No. 2 slide rail, a No. 2 rack and a U-shaped clamp. The No. 2 gear is rotatably installed on the top of the main oil tank, the No. 3 gear is rotatably installed on the top of the main oil tank, the No. 2 slide rail is fixedly installed on the top of the main oil tank, the No. 2 rack is slidably installed inside the No. 2 slide rail, and the U-shaped clamp is fixedly installed on the side of the No. 2 rack away from the No. 3 gear. The movement of the pressure plate drives the U-shaped clamp to move, and the U-shaped clamp moves toward the middle and clamps the telescopic refueling pipe. During the process of the auxiliary oil tank refueling the main oil tank, the telescopic refueling pipe is clamped to provide a safe refueling space for it, so as to prevent the telescopic refueling pipe from moving excessively during the refueling process, causing the lubricating oil to leak to the outside of the main oil tank, causing unnecessary trouble or even danger.

[0012] According to the above technical solution, the clamping device also includes a turntable, a fourth gear, a sliding door, an L-shaped plate, a third rack, a conical plate, a revolving door and a stopper.

The movement of the first rack during refueling is limited by the No. 1 card block being inserted into the No. 1 card slot to prevent the pressure plate of the main oil tank from continuously moving downward due to gravity during refueling, resulting in failure to fully refuel the main oil tank after refueling.

[0013] According to the above technical solution, the No. 1 rack is meshed with the No. 2 gear, the No. 2 gear is meshed with the No. 3 gear, and the No. 3 gear is meshed with the No. 2 rack. The U-shaped clamp plate moves toward the middle to drive the sliding door to slide. When refueling is needed, the sliding door slides open, thereby ensuring the safety of the main oil tank when refueling is not needed, preventing the fuel port from being always open, which may cause danger, and preventing the fuel port from being always open, causing the lubricating oil to be contaminated and its lubrication ability to be weakened.

[0014] According to the above technical solution, the No. 4 gear is meshed with the No. 3 rack, a No. 2 slide groove is provided on the top of the turntable, and a No. 3 slide groove is provided on the top of the main oil tank.

[0015] The present invention provides a ton bag grab hook, which has the following beneficial effects: (1) In this invention, a clamping shaft and a snap fastener are provided on the mounting base plate. The snap fastener can be a Velcro with stickiness. The snap fastener can adsorb the lifting lug of the ton bag to the mounting base plate through friction. A pressure sensor is installed at the air pipeline of the lifting cylinder. When the lifting lug is pulled upward, the weight of the ton bag triggers the pressure sensor. The control cabinet detects the pressure signal and controls the tensioning cylinder to release the hook assembly, thereby clamping the lifting lug. During the clamping, the hook is pulled downward under the action of gravity, and the positioning pin under the hook acts as a mechanical limit to prevent the hook from being pulled off the hook due to the pulling force of the heavy object. After the hook assembly is closed, the external lifting and handling equipment starts to carry the ton bag. After the goods are moved, the ton bag contacts the load-bearing pallet or shelf, the gravity on the lifting ear decreases and gradually tends to 0, the pressure sensor is released, the control cabinet receives the signal, controls the tensioning cylinder to loosen the hook, and the two positioning pins above the hook act as a mechanical limiter. The equipment is lifted upward, and the snap fastener automatically unhooks the goods from the hook under the action of gravity, achieving the purpose of unmanned automatic hanging of the ton bag lifting ear, saving time and effort and improving work efficiency.

[0016] (2) The invention introduces lubricating oil into the oil pipe through the main oil tank, and the oil pipe sends the lubricating oil to the rotating shaft of the hook, so that the hook is lubricated by the lubricating oil, allowing the hook to fully grasp the ton bag during operation and smoothly complete the grasping action, thereby preventing the hook from being deprived of lubricating oil for a long time, causing some components of the hook to be seriously worn out and lose their original functions during daily work, causing the hook to fail to grasp and the grasping process to be slow and unsmooth during daily work; lubricating oil is introduced into the telescopic refueling pipe through the auxiliary oil tank, and the telescopic refueling pipe sends the lubricating oil to the main oil tank, so that when the lubricating oil in the main oil tank needs to be replenished, the auxiliary oil tank can promptly send the lubricating oil to the main oil tank, allowing the main oil tank to continuously provide lubricating oil to the hook, thereby preventing the main oil tank from being insufficient to provide lubricating oil to the hook for lubrication, causing the hook to be unable to work normally.

[0017] (3) The invention drives the U-shaped clamping plate to move by the movement of the pressure plate. The U-shaped clamping plate moves toward the middle and clamps the telescopic filling pipe. When the auxiliary tank is refueling the main tank, the telescopic filling pipe is clamped to provide a safe refueling space for the main tank. This prevents the telescopic filling pipe from moving excessively during the refueling process, causing the lubricating oil to leak to the outside of the main tank, causing unnecessary trouble or even danger. The No. 1 clamping block is clamped into the No. 1 clamping slot to limit the movement of the No. 1 rack during refueling. This prevents the pressure plate of the main tank from moving downward continuously due to the influence of gravity during the refueling process, resulting in the main tank not being fully refueled after refueling.

[0018] (4) The invention drives the sliding door to slide by moving the U-shaped clamp plate toward the middle. When refueling is needed, the sliding door slides open, thereby ensuring the safety of the main fuel tank when refueling is not needed, preventing the fuel port from being always open, which may cause danger, and preventing the lubricating oil from being contaminated and its lubricating ability from being weakened due to the fuel port being always open. When the telescopic refueling pipe moves downward, the revolving door contacts the conical plate and opens. When refueling is needed, the revolving door opens, thereby preventing the lubricating oil from leaking and causing danger when refueling is not needed. BRIEF DESCRIPTION OF THE DRAWINGS
