[0002] A refueling device is a device used to add fuel or lubricants to mechanical equipment, vehicles or other equipment that requires fuel or lubricants. Tower cranes play a very important role on construction sites, ensuring the smooth progress of construction projects. During the use of tower cranes, it is necessary to regularly refuel the tower crane's tank.

[0003] Since the engine of the tower crane is located at a high altitude, it is not convenient to refuel it with general refueling equipment. The traditional refueling method is to manually pour diesel into the fuel tank of the tower crane bucket by bucket using a portable oil bucket for refueling. This refueling method is very time-consuming and labor-intensive. Therefore, we propose an automatic refueling device for a tower crane to solve the above problem. Utility Model Content

[0007] Preferably, the oil outlet is connected to the corresponding oil storage tank through the top opening, and the oil delivery pipe is connected to the corresponding oil storage tank through the bottom opening.

[0008] Preferably, the conveying drive mechanism includes a motor and a driving rod. The motor is fixedly mounted on one side of the middle turntable, and one end of the driving rod is fixedly mounted on the output shaft of the motor. The other end of the driving rod is rotatably mounted on an inner wall of one side of the rotating groove. The driving rod is fixedly connected to the conveying disk. Through the conveying drive mechanism, the petroleum can be intermittently transported from the oil barrel to the tower crane oil tank.

[0009] Preferably, the multiple oil storage tanks are distributed in a circular array, and the capacities of the multiple oil storage tanks are consistent.

[0010] Preferably, the control box is located at a lower position on one side of the oil drum, and the motor is electrically connected to the control box.

[0011] Preferably, the plurality of lifting rings are distributed in a circular array, and circular grooves are provided in the lifting rings, so as to facilitate tying the slings of the tower crane to the plurality of lifting rings, thereby lifting the oil barrels filled with diesel to a suitable position at a high altitude.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the automatic refueling device for the tower crane, by tying the sling of the tower crane to a plurality of lifting rings, lifts the oil barrel filled with diesel to a suitable position at a high altitude, and rotates the upper oil storage tank filled with diesel to a lower position through a conveying drive mechanism, so that the diesel in the oil storage tank is intermittently transported to the oil pipeline through the bottom opening, and then the diesel is added to the oil tank of the tower crane through the oil outlet, thereby realizing automatic intermittent continuous refueling of the tower crane, and there is no need for manual transport of the portable oil tank for refueling.
