Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of replacement of drilling equipment, and particularly relates to a replacement device for a traveling block in drilling equipment. Background Art
[0002] In the related art, during normal use, if it is necessary to replace the traveling block, without lowering the derrick, the following steps are carried out:
[0003] (1) Before replacement, all the equipment connected under the traveling block needs to be unloaded completely. When the traveling block is slowly lowered to be close to the rotary table surface, with the cooperation of a pneumatic winch, the traveling block is pulled by a wire rope sling, and after the traveling block is placed at the entrance of the substructure ramp, it is slowly slid to the lower end of the substructure ramp.
[0004] (2) Loosen the dead line anchor and the live line anchor, and start to draw the drilling wire rope with a drum rope extractor until all is drawn out.
[0005] (3) If it is necessary to replace the traveling block, lift the old traveling block away, and then lift the traveling block to be replaced to the lower end of the substructure ramp.
[0006] (4) Start the operation of threading the drilling wire rope. First, connect a 1 / 4″ lead rope to one end of the drilling wire rope with a clamp. When tying the lead rope, hang one end of the lead rope on the pneumatic winch and lift it to the crown block through the pneumatic winch. Reserve about 1.5 meters of the length of the drilling wire rope head. When the drilling wire rope is pulled to below the crown block platform, the derrickman fixes the drilling wire rope with a section of rope, unties the lead rope clamp, passes through the first crown block pulley and then fixes the lead rope again. Subsequently, still with the cooperation of the pneumatic winch, the drilling wire rope is pulled to the substructure ramp, and then passes through the first traveling block pulley, and all the pulleys are threaded in accordance with the above steps.
[0007] (5) After threading the traveling block, carefully check the crown block and the traveling block pulleys. After ensuring that there is no error, with the cooperation of the pneumatic winch, pull one end of the drilling wire rope to the drum, install and fix the live line head of the drum, arrange the drilling wire rope on the drum, and finally fix the dead line anchor.
[0008] In summary, at present, the operations of replacing the traveling block and the wire rope in the derrick drilling industry are completely completed by the cooperation of manpower and on-site equipment. The existing technology requires a large number of equipment and personnel, and the safety risk of high-altitude operation is high. More than 2 derrickmen are required to work at heights, and the height from the ground can reach 50 meters. The operation is complex and cumbersome, and the operation time is long. It is easy to make mistakes and cause rework, increasing the cost. Content of the Utility Model
