The crown block slide wire anti-scraping device for the petroleum drilling machine comprises a vertical plate, a transverse plate is fixedly installed at the position, close to the top, of the right side of the vertical plate, a plurality of identical transverse plates are arranged on the right side of the transverse plate, a connecting mechanism is arranged between every two transverse plates, and threaded blocks are movably connected to the bottoms of the transverse plates; by arranging an air cylinder, a gear, rack side blocks and clamping blocks, after a slide wire penetrates through the space between the two clamping blocks, the air cylinder is driven, so that the air cylinder pushes a right rack to move, the right rack drives the gear to rotate, the gear drives a left rack to move, and the slide wire is clamped in the clamping blocks. The two racks drive the two side blocks to move relatively, the two side blocks drive the corresponding clamping blocks to move, the slide wire is fixed through the relative movement of the two clamping blocks, only the air cylinder needs to be driven to contract during subsequent disassembly, and compared with a traditional bolt fixing mode, the slide wire fixing device is more convenient to use.
本发明公开了一种石油钻机用天车滑线防刮装置,包括竖板,所述竖板右侧靠近顶部处固定安装有横板,所述横板右侧设有若干个相同的横板,且两个所述横板之间设有连接机构,所述横板底部活动连接有螺纹块,所述螺纹块上螺纹连接有螺杆,相邻两个所述螺杆相互连接,通过设置有气缸、齿轮、齿条侧块和夹块,在滑线穿过两个夹块之间后,驱动气缸,使得气缸推动右侧齿条移动,右侧齿条带动齿轮转动,齿轮带动左侧齿条移动,两个齿条带动两个侧块相对移动,两个侧块带动对应夹块移动,通过两个夹块的相对移动实现对滑线的固定操作,且后续拆卸只需驱动气缸收缩即可,相较于传统的螺栓的固定方式而言,更加便捷。
