Abstract
The utility model relates to a pneumatic brake controller for petroleum drill, in particular to a closed-loop controller to control uniform speed slamming down of a winch brake and a hook block assembly for petroleum drill remotely by making use of pneumatic principle. The controller consists of a driller control room, a pneumatic brake device, a well drilling winch and an electrical system. One end of a cylinder in the pneumatic brake device is connected with a pneumatic brake in the driller control room through an air pipeline. The piston end of the cylinder in the pneumatic brake device is connected with a brake shaft in the well drilling winch through a transmission shaft. The electrical system is respectively connected with an electronic control valve in the well drilling winch and the driller control room. The utility model can lead the hook block assembly to be slammed down at a uniform speed momently when the driller is operated to a certain speed.

The controller has ensured the security of petroleum drill, reduced the working intensity of driller and improved the automatic control level of petroleum drill.
Description
(1) technical field:
The utility model relates to a kind of device that oil-well rig is controlled, the closed-loop control device that utilizes oil drilling winch brake of pneumatic principle far distance controlled and hook block at the uniform velocity to transfer specifically.
(2) background technology: the lowering velocity of normal braking, snub and the hook block of general oil-well rig all is to handle the winch brake lever by the driller to control the winch drum rotating speed, when hook block is transferred, speed can be more and more faster, transfer if will remain a constant speed, the driller will adjust the brake weight size at any time, the driller operates at full stretch, and is tired easily.
(3) summary of the invention: technical problem to be solved in the utility model is how by pneumatic principle borer brake and hook block at the uniform velocity to be transferred.Specifically, project organization of the present utility model is: a kind of oil-well rig aerodynamic brake control device, it is by driller control house (1), gas control brake gear (2), drilling well winch (3) and electrical system (4) constitute, cylinder one end in the gas control brake gear (2) is stopped with the gas in the driller control house (1) by gas piping and is linked to each other, cylinder piston end in the gas control brake gear (2) joins by the brake axle (3.1) in power transmission shaft (2.3) and the drilling well winch (3), and electrical system (4) links to each other with electrically-controlled valve (1.5) in the driller control house (1) with drilling well winch (3) respectively.
Cylinder is divided into and often opens cylinder (2.2) and normally closed cylinder (2.1) in the gas control brake gear (2), and respectively with driller control house (1) in Chang Kaiqi stop (1.4) and normally closed gas stop (1.3) be connected.
In normally closed cylinder (2.1), be equipped with the spring of the snub that can realize the drilling well winch.
Have signal processor (4.1) and encoder (4.2) in the electrical system (4), encoder (4.2) is connected on winch drum shaft (3.3) and goes up and the tach signal of gathering is input in the signal processor (4.1), treated and amplify after the signal of telecommunication go to control electrically-controlled valve (1.5), make air pressure signal that changes with drum rotation speed of electrically-controlled valve (15) output, by shuttle valve (1.6) control signal amplifier (1.7), make adjustable air pressure of its output, and send into and often open cylinder (2.2) in the gas control brake gear (2).
The utlity model has following advantage: when (1) can make the driller operate a certain speed, hook block remained a constant speed constantly and transfers.(2) when hook block is transferred, the driller can control unclamping of the pressure of the drill size, brake very easily and stop tight.On the other hand, utilize pneumatic control also to improve the sensitivity of brake.(3) when gas circuit breaks down, gas control brake system gas out of hand, it can automatically check hook load by spring force firmly, has guaranteed the safety of oil-well rig, has alleviated driller's labour intensity, has improved the automatic control level of oil-well rig.
The utility model operating principle is described below:
Source of the gas is given the native system air feed.
The driller is by the output pressure of the manual pressure regulating valve 1.4 in the operation driller control house 1, again by shuttle valve 1.6 control signal amplifiers 1.7, make adjustable air pressure of its output, and send into and often open cylinder 2.2 in the gas control brake gear 2, gas pressure is converted into mechanical force, thereby realizes often opening the function that gas is stopped.
The driller is by the output pressure of the manual pressure regulating valve 1.3 in the operation driller control house 1, control signal amplifier 1.2 makes gas-pressure adjustable of its output, and sends into the normally closed cylinder 2.1 in the gas control brake gear 2, gas pressure is converted into mechanical force, thereby realizes the function that normally closed gas is stopped.After the front is converted into mechanical force with atmospheric pressure, drive the power transmission shaft 2.3 that is connected with piston rod, and then drive the brake axle 3.1 of drilling well winch 3, realize brake winch drum 3.2.
When the rotating speed of winch drum 3.2 is below or above the rotating speed of requirement, be connected on the tach signal of the coding 4.2 collection winch drum shafts 3.3 on the winch drum shaft 3.3, and be input in the signal processor 4.1, treated and amplify after the signal of telecommunication go to control electrically-controlled valve 1.5, make air pressure signal that changes with drum rotation speed of electrically-controlled valve 1.5 outputs, by shuttle valve 1.6 control signal amplifiers 1.7, make adjustable air pressure of its output, and send into and often open cylinder 2.2 in the gas control brake gear 2, by the linkage of narrating previously, adjusting is controlled the purpose that rig load is at the uniform velocity transferred to the brake weight of cylinder thereby reach.
When gas circuit broke down or have anti-collision signal input Pneumatic valve 1.1 to die, normally closed cylinder 2.1 was died, by the snub of spring force realization to winch.
