Be attached with the drilling well tong of well head, the free end of steel wire rope is located near drilling well tong, now baffle plate also therewith by
Near band to drilling well tong, expansion plate is extended therewith, and the barrier of the left and right sides is carried out to steel wire rope, once steel wire rope breaks
The limitation being fixedly connected of through hole, the splashing of steel wire rope in accident, the stop and baffle plate due to the expansion plate of its left and right sides
It can be limited by largely, so that injury of the reduction of high degree to the driller near rig floor, realizes reduction hydraulic pressure
Steel wire rope on cat head break after harm purpose.
It is preferred that, the expansion plate is arranged on the hydraulic catwork body of the rope outlet left and right sides by rotating shaft.It is to stretch
Contracting plate can be rotated on hydraulic catwork around the shaft, can suitably be protected hence for different upper shackle height
Shield, is adjusted flexibly the angle of expansion plate as needed, improves applicability of the present utility model.
It is preferred that, the expansion plate is made up of N sections of sheet materials, and N sections of sheet materials are from the connection end of expansion plate and hydraulic catwork, to stretching
The connection end of contracting plate and baffle plate, width is gradually reduced with height, and every section of sheet material can insert larger one block of sheet material adjacent thereto
In, wherein N is the integer more than or equal to 2.It is that sheet material of the expansion plate by N sections of width with highly gradually reducing is constituted, every section of plate
Material can be retracted into adjacent bigger one section sheet material so that expansion plate is the structure of mechanical retractable bar, so as to realize
Flexible function.
It is preferred that, two pieces of expansion plates are parallel to each other and perpendicular to baffle plate.So that two pieces of composition sides between expansion plate and baffle plate
The region of shape, is easy to steel wire rope freely to walk wherein, it is ensured that to the protection iris action of steel wire rope.
It is preferred that, the part of the steel wire penetrating through hole is bonded or is welded on through-hole wall.By being bonded or welding
Ensure the secure and reliable connection between steel wire rope and baffle plate, it is ensured that baffle plate can be moved with moving for steel wire rope, from
And ensure the protective action to steel wire rope.
The utility model compared with prior art, has the following advantages and advantages：
The through hole that the utility model is used on the supplemental protective structure of rig floor hydraulic catwork, steel wire penetrating baffle plate, then with
The drilling well tong of well head is attached, and the part of steel wire penetrating through hole is fixed on through-hole wall so that steel wire rope movement is stretched
When long, baffle plate is also moved therewith by the expansion plate of both sides, in baffle plate moving process expansion plate be can extend or
Shorten, from without influenceing the normal of steel wire rope on hydraulic catwork to use.Baffle plate is taken to the free end of steel wire rope when using
Near drilling well tong, expansion plate is extended therewith, and the barrier of the left and right sides, the thing once steel wire rope breaks are carried out to steel wire rope
Therefore, the limitation being fixedly connected of through hole in the stop and baffle plate due to the expansion plate of its left and right sides, the splashing meeting of steel wire rope
Limited by largely, so that injury of the reduction of high degree to the driller near rig floor, realizes reduction hydraulic pressure cat
Steel wire rope on head break after harm purpose.
