The invention discloses a crown block jacking prevention device for a petroleum derrick. The crown block jacking prevention device comprises the petroleum derrick, wherein an infrared sensing device is arranged at the middle upper part of the petroleum derrick; a derrick crown block is arranged at the top of the petroleum derrick; a traveling block is arranged at the middle lower part of the petroleum derrick; a numerical control winch is arranged at the bottom of the outer side of the petroleum derrick; a winch numerical control operation panel is arranged on the side surface of the numericalcontrol winch; a winch base is arranged at the bottom of the numerical control winch; the derrick crown block, the traveling block and the numerical control winch are connected through a steel wire rope; a distance sensor is arranged at the top of the traveling block; and the distance sensor sends the distance between the derrick crown block and the traveling block to a computer through a wireless network. When the traveling block moves to the position of the infrared sensing device, infrared rays are affected, so that the alarming and reminding effects are achieved, and the traveling block is prevented from jacking the derrick crown block; and by using the device, the tripping operation of an oil well can be safely and conveniently carried out, and the crown block can be effectively prevented from being jacked and collided during traveling.

    本发明公开了一种石油井架防顶天车装置,包括:石油井架,石油井架的中上部设置红外感应装置,在石油井架的顶部设置井架天车,在石油井架的中下部设置游动滑车,在石油井架的外侧底部设置数控绞车,在数控绞车的侧面设置绞车数控操作盘,在数控绞车的底部设置绞车底座,井架天车、游动滑车和数控绞车通过钢丝绳连接,所述游动滑车顶部设置有距离传感器,所述距离传感器通过无线网将井架天车于游动滑车之间的距离发送到电脑上。使得游动滑车在运动到红外感应装置位置时,红外线接受收到影响,达到报警提醒的作用,避免游动滑车顶上井架天车,使用该装置可以安全、方便地进行油井起下钻作业,又可以有效预防游动上行时顶撞天车。
