A through hole is formed in the bottom surface of the oil tank 3 in the vertical direction, and the length direction of the through hole points to the pulley 21. Slide in the through-hole and wear to be equipped with one and let out oil pole 4, the directional pulley 21 in bottom of draining pole 4, and let out the side of oil pole 4 and seted up draining groove 41, the top of draining groove 41 all seals the setting with the bottom, let out the both sides of oil pole 4 and be connected with an auxiliary rod 44 respectively, the length direction of auxiliary rod 44 is parallel with the length direction of draining pole 4. Each auxiliary lever 44 corresponds to one cam 22, and the bottom end of each auxiliary lever 44 abuts against the side surface of the corresponding cam 22.

When the gantry crane slides, the wheel shaft 2 rotates to drive the pulley 21 and the cam 22 to synchronously rotate. When the cam 22 rotates, the oil drainage rod 4 is pushed to slide in a reciprocating manner along the vertical direction, and when the top end of the oil drainage groove 41 enters the inside of the oil tank 3, the lubricating oil in the oil tank 3 enters the oil drainage groove 41 and is stored in the oil drainage groove 41; along with letting out the slip of oil pole 4, the bottom of draining groove 41 exposes from the bottom surface of oil tank 3, when the lubricating oil of storing in draining groove 41 can follow draining pulley 21 and rotate along with shaft 2, the lubricating oil on the pulley 21 side can disperse to between pulley 21 and the slide rail 1, and then lubricate between pulley 21 and the slide rail 1, self-lubricating arrangement in this scheme, every gantry crane slides a section distance, can carry out a lubrication to between pulley 21 and the slide rail 1, do not need operating personnel manual to lubricate base 11, thereby conveniently maintain the gantry crane.

The length of draining groove 41 is greater than the thickness of 3 diapalls of oil tank, the side top shaping of draining pole 4 has dog 42, sliding sleeve is equipped with only an oil section of thick bamboo 5 on draining pole 4, only an oil section of thick bamboo 5 is located oil tank 3, and offer the spout 52 that is used for holding dog 42 on the inside wall of only an oil section of thick bamboo 5, the top of spout 52 seals the setting, the uncovered setting in bottom, the cell wall and the dog 42 sliding fit of spout 52, and the length of spout 52 and the thickness sum of 3 diapalls of oil tank are greater than dog 42 and the distance of ending the oil groove 51 bottom.

The length of the oil drainage groove 41 is set to be larger than the thickness of the bottom wall of the oil tank 3, and a stop 42 is arranged at the top end of the side surface of the oil drainage rod 4. When the oil drainage rod 4 slides towards the inside of the oil tank 3, the oil drainage rod 4 jacks up the oil stopping cylinder 5 through the stop block 42, so that the lubricating oil in the oil tank 3 can flow into the oil drainage groove 41 and be stored in the oil drainage groove 41; when the oil drainage rod 4 slides towards the pulley 21, the oil stop block is firstly abutted against the bottom surface of the inner wall of the oil tank 3, so that the lubricating oil in the oil tank 3 is prevented from continuously entering the oil drainage groove 41, and then the bottom end of the oil drainage groove 41 is exposed from the bottom surface of the oil tank 3, and the lubricating oil stored in the oil drainage groove 41 is sprinkled on the pulley 21. When the portal crane slides, if the both ends of draining groove 41 are located the inside and outside of oil tank 3 respectively, then the bottom surface of ending the oil piece supports tightly with the inner wall bottom surface of oil tank 3 to guarantee that oil tank 3 is inside all can't communicate with the external world through draining groove 41 at any moment, avoid the lubricating oil in the oil tank 3 to last to spill from draining groove 41, reduce the waste to lubricating oil.

The oil stopping groove 51 is formed in the edge of the bottom end of the inner wall of the oil stopping cylinder 5, the oil stopping ring 31 is fixedly connected to the bottom surface of the inner wall of the oil tank 3, when the bottom surface of the oil stopping cylinder 5 abuts against the bottom surface of the inner wall of the oil tank 3, the oil stopping ring 31 is embedded with the oil stopping groove 51, the seepage path of lubricating oil in the oil tank 3 to the oil drainage groove 41 can be increased, therefore, when the oil stopping block abuts against the bottom surface of the inner wall of the oil tank 3, the lubricating oil in the oil tank 3 is prevented from flowing into the oil drainage groove 41, and the waste.

The bottom surface of the oil-stopping cylinder 5 is fixedly connected with a sealing gasket 53. When the oil stopping block abuts against the bottom surface of the inner wall of the oil tank 3, the sealing gasket 53 can increase the sealing performance between the bottom surface of the oil stopping cylinder 5 and the bottom surface of the inner wall of the oil tank 3, so that the lubricating oil in the oil tank 3 is prevented from flowing into the oil drainage groove 41, and the waste of the lubricating oil is reduced.

Two shunting blocks 43 are fixed on the oil drain rod 4, the two shunting blocks 43 are respectively positioned at two sides of the oil drain rod 4, one end of each shunting block 43 is connected with the oil drain rod 4, and the other end of each shunting block 43 points to the joint of the adjacent wheel axle 2 and the base 11. The shunting block 43 is obliquely arranged, and one end of the shunting block 43 connected with the oil drainage rod 4 is higher than the other end. The lubricating oil flowing on the oil drain rod 4 can be divided into two dividing blocks 43 and guided to the joint of the wheel axle 2 and the base 11 by the dividing blocks 43, so that the joint of the wheel axle 2 and the base 11 is lubricated, and the rotating friction force between the wheel axle 2 and the base 11 is reduced.
