Abstract
The utility model discloses a kind of oil-well rig collision-proof protector, it is characterized in that: comprise weight, pullswitch and lifting rope; Described weight is annular, is enclosed within tourist bus dead line, can moves up and down along tourist bus dead line; Described pullswitch is fixed on attachment point near tourist bus terminal, and this pullswitch is connected with weight by lifting rope.Described pullswitch also connects colliding crown block by electromagnetic valve and controls gas circuit, controls tourist bus motion by the action of pullswitch.The utility model structure is simple, reliable in action.
Description
Technical field
The utility model relates to petroleum drilling safety features, specifically a kind of oil-well rig collision-proof protector.
Background technology
Oil-well rig tourist bus anti-collision is a critical component of rig safe operation.Although according to petroleum drilling safety management regulations, every bench drill machine must install 3 cover colliding crown blocks to guarantee the generation of avoiding touching serious accident.Even if under requirement strict like this, within nearly 2 years, collision case still happens occasionally.Its reason is that installations and facilities unfailing performance also exists some problems.
The anticollision device that current rig is installed mainly contains: the electronics colliding crown block that the control of pulleying valve, weight hammer type colliding crown block and coder calculate.The service condition of the most frequently used colliding crown block: 1, pulleying valve is arranged on winch drum, relies on steel rope floor height and movement position to carry out trigger action, triggers not too reliable.2, weight hammer type colliding crown block is positioned by the horizontal steel rope that draws under being arranged on overhead traveling crane, and tourist bus upper limit of movement location triggered is horizontal draws steel rope, drives lower step weight air cock to realize anti-collision control by steel rope guiding; Steel rope guiding is loaded down with trivial details, and gas circuit controls response lag, slow movement.3, electronics colliding crown block is all drive coder to carry out calculating the movement travel of tourist bus by drum rotating substantially.This colliding crown block Problems existing is exactly, the load variations of steel rope, the accurate performance of calculating of elongation variable effect coder.Need regularly to carry out zero verification; And transmission device calculation procedure is comparatively complicated, fault rate is high, poor reliability.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and provide a kind of oil-well rig collision-proof protector, this device reliability is high, and structure is simple, easily manufactured.
Realizing the technical solution of the utility model is: a kind of oil-well rig collision-proof protector, comprises weight, pullswitch and lifting rope; Described weight is annular, is enclosed within tourist bus dead line, can moves up and down along tourist bus dead line; Described pullswitch is fixed on attachment point near tourist bus terminal, and this pullswitch is connected with weight by lifting rope.
Described pullswitch connects colliding crown block by electromagnetic valve and controls gas circuit, controls tourist bus motion by the action of pullswitch.
Described weight inner ring is provided with anti-wearing liner.
Be flush fit between described abrasionproof lining and weight.
The opening of described weight connects with bolt.
Described pullswitch is preferably fixedly installed in overhead traveling crane base or is fixed on tourist bus dead line termination by wire clips clamp.
Described lifting rope length is more than 1.5 meters.
The beneficial effects of the utility model are:
1, the utility model structure is simple, reliable in action.With weight through the direct connecting stay wire switch of lifting rope, intermediate link is few, and problem points is just few, and reliability is just high, can also effectively solve response lag problem.
2, when brake is highly determined, pullswitch is fixed on below overhead traveling crane base, is not arranged on dead line, so both can meet the inadequate problem of braking path, what be also beneficial to drilling process switches steel rope, in order to avoid forget that dismounting wire clips clamp causes fault.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Number in the figure: 1-weight, 2-tourist bus dead line, 3-wire clips clamp, 4-pullswitch, 5-lifting rope, 6-anti-wearing liner, 7-bolt.
Detailed description of the invention
As shown in Figure 1, a kind of oil-well rig collision-proof protector, comprises weight 1, pullswitch 4 and lifting rope 5; Described weight 1 is annular, is enclosed within tourist bus dead line 2, can moves along tourist bus dead line 2; Pullswitch 4 is fixedly mounted at tourist bus dead line 2 termination wire clips clamp 3; Described pullswitch 4 is connected with weight 1 by lifting rope 5; This pullswitch 4 connects colliding crown block by electromagnetic valve and controls gas circuit, controls tourist bus motion by the action of pullswitch 4.Described weight 1 inner ring is also provided with anti-wearing liner 6.Be flush fit between described abrasionproof lining 6 and weight 1.The opening of described weight 1 connects with bolt 7.Described lifting rope 5 length is 1.5 meters.
Working process of the present utility model is: annular weight 1 is looped around on tourist bus dead line 2, annular weight 1 is arranged on the up high position of tourist bus, when tourist bus meets or exceeds this position, tourist bus contacts annular weight 1 and drives annular weight 1 up, cause pullswitch 4 action, pullswitch 4 connects colliding crown block by electromagnetic valve and controls gas circuit, controls tourist bus motion by the action of pullswitch 4; Perform anti-collision defencive function.
