Abstract
The utility model provides a two winch oil -well rigs play to rise system based on move fixed pulley train, including two winches, the derrick, hook and wire rope, these two winches are located the both sides of derrick, wire rope's one end is connected with a winch drum, wire rope's the other end passes behind the cylinder of this winch, walk around first fixed pulley of this winch orientation of orientation on the overhead traveling crane, walk around first movable pulley of this winch orientation of orientation on the tourist bus again, walk around the second fixed pulley in the overhead traveling crane after that, walk around the second movable pulley on the tourist bus again, analogize in proper order, cylinder with another winch after walking around all fixed pulleys and movable pulley in proper order is connected. This rises the system and adopts two winches to twine or relieve wire rope simultaneously to have accomplished the work that rises and descend the tourist bus, promoted the operating efficiency of well drilling work.
Description
Technical field
The utility model belongs to oil-well rig equipment technical field, relates to a kind of oil-well rig to hoisting system, is particularly a kind ofly convenient to the multiple twin car oil-well rig hoisting system based on dynamic fixed pulley train carrying out drilling fast.
Background technology
Existing oil-well rig hoisting system is primarily of winch, traveling system (comprising steel rope, overhead traveling crane, tourist bus and hook) and the derrick composition hanging traveling system, steel rope one end is fixed on the cylinder of winch, the other end is fixed on fastener of dead-line, the oscilaltion of tourist bus is only wound around by a winch or decontrols steel rope and realizes, therefore, its drilling, more bit change, control that drill bit is sent to, the velocity ratio of case in etc. is slower.
Summary of the invention
The purpose of this utility model is to provide a kind of multiple twin car oil-well rig hoisting system based on dynamic fixed pulley train, can fast lifting and put down tourist bus, promotes drilling efficiency.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of multiple twin car oil-well rig hoisting system based on dynamic fixed pulley train, comprise derrick, hook, steel rope and two winches being positioned at derrick both sides, one end of steel rope is connected with a winch drum, the other end of steel rope is through after the cylinder of this winch, walk around on overhead traveling crane towards first of this winch direction fixed pulley, walk around again on tourist bus towards first of this winch direction movable pulley, then second fixed pulley in overhead traveling crane is walked around, walk around second movable pulley on tourist bus again, the like, be connected with the cylinder of another winch until walk around all fixed pulleys successively with after movable pulley.
The utility model hoisting system is wound around simultaneously or decontrols steel rope by two winches makes tourist bus (tourist bus and running block) complete fast lifting and put down action, and then realize quick drilling, more bit change in drilling operation course, control drill bit and send to and cased work efficiency, thus improve the operating efficiency of drilling well work.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model hoisting system.
In figure: 1. the first winch, 2. steel rope, 3. overhead traveling crane, 4. tourist bus, 5. hook, 6. derrick, 7. the second winch.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, the utility model hoisting system, comprise the first winch 1 set gradually side by side, derrick 6 and the second winch 7, derrick 6 top is provided with overhead traveling crane 3, overhead traveling crane 3 is fixed pulley group, this hoisting system also comprises tourist bus 4, tourist bus 4 is running block, the lower drop handle of tourist bus 4 is connected with hook 5, the cylinder of the first winch 1 is connected with one end of steel rope 2, after the other end of steel rope 2 walks around the cylinder of the first winch 1, then first fixed pulley towards the first winch 1 direction on overhead traveling crane 3 is walked around, walk around first movable pulley towards the first winch 1 direction on tourist bus 4 again, then second fixed pulley in overhead traveling crane 3 is walked around, walk around second movable pulley on tourist bus 4 again, the like, be connected with the cylinder of the second winch 7 until walk around all fixed pulleys successively with after movable pulley, namely all fixed pulleys and movable pulley are connected in series by steel rope 2 successively, overhead traveling crane 3, tourist bus 4, steel rope 2 and hook 5 form traveling system.
First winch 1, derrick 6 and the second winch 7 are installed on rig substructure, and hook 5 is connected on the lower drop handle of tourist bus 4, and overhead traveling crane 3 is arranged on the top of derrick 6.The cylinder of the first winch 1 passes through the fast end wire rope handling of steel rope 2 on the fast sheave of overhead traveling crane 3, fast sheave by steel rope 2 wire rope handling in the fixed pulley group of overhead traveling crane 3, again by steel rope 2 wire rope handling on the running block of tourist bus 4, again by steel rope 2 wire rope handling in the fixed pulley group of overhead traveling crane 3, final steel rope 2 is worn back from the fixed pulley group of overhead traveling crane 3 and is connected with the cylinder of the second winch 7.
During the work of the utility model hoisting system: the wire rope drum clickwise of the first winch 1, the wire rope drum left-hand revolution of the second winch 7, two winches are wound around from two ends simultaneously and pull steel rope 2, and steel rope 2 draws tourist bus 4 upward movement, realizes hoisting of drilling tool.
When needing to transfer drilling tool: the wire rope drum left-hand revolution of the first winch 1, the wire rope drum clickwise of the second winch 7, two winches loosen steel rope 2 simultaneously, and tourist bus 4 and hook 5 and drilling tool drive steel rope to move downward by gravity, realize transferring of drilling tool.
First winch 1 is as main winch, and the second winch 7 is as secondary winch, and the rope woolding speed of two winches can be different, and this can regulate in the control system of rig of rig driller indoor.The rotating speed of secondary winch can carry out the setting of 0 ~ 100% with reference to the rotating speed of main winch.
The utility model provide a kind of can carry out drilling, based on the rig of the multiple twin car hoisting system of dynamic fixed pulley train, dead line end one end of rig is had to change use boring winch into by showing (former), formation multiple twin car hoisting system of rig makes full use of two winches to carry out being wound around and decontroling steel rope simultaneously, realizes fast lifting and put down tourist bus carrying out drilling operation.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of rig of the multiple twin car hoisting system based on dynamic fixed pulley train, and hoisting system comprises two winches, derrick, traveling system (traveling system is made up of overhead traveling crane, tourist bus, steel rope and hook).The hoisting system essence of rig is a set of assembly pulley, comprises fixed pulley group and running block, and overhead traveling crane belongs to fixed pulley group, and tourist bus belongs to running block.Two winches are installed on winch base, one end of steel rope is fixed on winch drum side, after being wound around by cylinder, be connected on the fast sheave of rig overhead traveling crane, again through on the running block of tourist bus and overhead traveling crane fixed pulley group, final steel rope is worn back by overhead traveling crane and is fixed on the cylinder of another well drilling hoist.It is boring winch that its technical scheme mainly will show that (former) have oil-well rig fastener of dead-line one end to change into use, and forms multiple twin car hoisting system of rig, is wound around simultaneously or decontrols by two winches the task that steel rope completes drilling.
