Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-5, the utility model provides an oil pipe elevator, including main part 1, the lockhole has been seted up at the middle part of main part 1, the slide has been seted up at the middle part of lockhole inner wall, the inside sliding connection of slide has crescent moon lock 3, crescent moon lock 3's one side seted up with crescent moon lock 3 vertically screw hole 8, the center of main part 1's one end articulates there is valve 13, one side fixedly connected with handle 15 of valve 13, fixed orifices 4 have all been seted up at the both ends at main part 1 top, the equal block in inside of two fixed orifices 4 is connected with lockpin 5, spout 9 has been seted up to the center level of the main part 1 other end, the inside sliding connection of spout 9 has transmission column 10, the inside fixed connection of slide and screw hole 8 is passed to the one end of transmission column 10.

Preferably, resistance increasing plates 2 are fixedly arranged on two sides of the slide way, so that the friction force between the elevator and the oil pipe can be effectively increased, and accidents caused by sliding of the oil pipe during lifting are avoided.

Preferably, the top of lockpin 5 is connected with locking screw 6, and the bottom of lockpin 5 articulates there is locking horizontal pole 7, can lock hoisting system, avoids rocking or oil pipe rocks because hoisting system, causes lockpin 5 to pop out, causes the incident.

Preferably, one side of spout 9 is provided with the spacing groove 12 with spout 9 vertical distribution, and spacing groove 12 corresponds the setting with spacing post 11, can prevent effectively that crescent 3 from rotating, can be to the better fixed of oil pipe.

Preferably, the locking columns 14 are fixedly connected to the two sides of one end of the valve 13 and one end of the slide way, the structure is simple and reasonable, and the oil pipe can be locked and fixed.

When the oil pipe elevator is used, firstly, the fixing pins in the locking columns 14 are pulled out by force upwards, then the valve 13 is rotated outwards by the handle 15, one end of the oil pipe to be lifted can be placed in the main body 1, then the limiting columns 11 are pushed, the limiting columns 11 drive the transmission columns 10 to slide in the sliding grooves 9, the transmission columns 10 drive the crescent moon locks 3 to rotate, the oil pipe is clamped, then the limiting columns 11 are rotated downwards by force, so that the limiting columns are clamped in the limiting grooves 12, the transmission columns 10 are fixed, the sliding of the transmission columns is prevented, then the valve 13 is closed by the handle 15, the valve 13 is fixedly locked by the fixing pins, then the lifting system can be clamped into the lugs at the two sides of the main body 1, then the two lockpins 5 are used for respectively penetrating through the two fixing holes 4, then the two locking cross rods 7 are sequentially rotated to be parallel to the bottom of the main body 1, then the two locking screws 6 are rotated downwards in sequence to be locked and fixed, at the moment, the lifting system is locked inside the lifting lug, because the lock pin 5 is locked with the main body 1, although the lifting system or the oil pipe shakes in the lifting process, the lock pin 5 cannot pop up, and is safer and more reliable, then the oil pipe can be lifted or descended, the friction force between the elevator and the oil pipe can be increased by the resistance-increasing plate 2 in the lifting or descending process, and the resistance-increasing plate is more stable and less prone to sliding, after the lifting is finished, the two locking screws 6 are rotated upwards in sequence, then the locking cross rod 7 is rotated to be parallel to the lock pin 5, the lock pin 5 is pulled out, the lifting system is taken down, then the fixing pin is pulled out upwards by force, the valve 13 is rotated through the handle 15, then the limiting column 11 is rotated upwards by force to be parallel to the transmission column 10, and then the crescent moon, when needing to change crescent moon lock 3, only need with the one end of transmission post 10 from the inside of screw hole 8 back-out, rotate crescent moon lock 3 afterwards, from one side of valve 13 roll out the slide, change new crescent moon lock 3, again with transmission post 10 screw in screw hole 8 in can, easy operation is convenient, during the transport, with during the promotion same method with lockpin 5 and fixed orifices 4 locking, can effectually avoid losing of lockpin 5.
