The invention provides a
coiled tubing clamping device and an injection head using the same, belonging to the field of
oil production and drilling equipment. The clamping device includes a
saddle-type clamping block and a clamping block seat, wherein the
saddle-type clamping block is connected to the clamping block seat. The clamping device is characterized in that two sides of the
saddle-type clamping block are provided with tongue-like platforms, the tongue-like platform is provided with an opening hole, the back part of the saddle-type clamping block is provided with a recess, two sides of the clamping block seat are respectively provided with a pair of bosses, the recess of the saddle-type clamping block is inserted into a slot formed by the clamping block seat bosses, a running clearance is left between the recess and the slot, and the clamping block seat is provided with a positioning screw for limiting the position of the saddle-type clamping block. The injection head comprises an oil
pipe clamping mechanism and a transmission chain, wherein the oil
pipe clamping mechanism is mounted on the transmission chain through two hinge pin holes on the clamping block seat. The technical proposal has the advantages that the abrasion of the oil
pipe can be effectively reduced, the clamping device has
operational reliability, and the clamping blocks are convenient in replacement.
