Abstract
The invention discloses an automatic start-stop device for a hydraulic and pneumatic tong. The automatic start-stop device is characterized in that two one-way pneumatic switches are respectively connected onto air inlet pipelines of a tong-sending air cylinder end and a tong-receiving air cylinder end of a tong receiving and sending air cylinder in parallel and are respectively connected with a left air inlet end and a right air inlet end of two piston air cylinders through air pipelines. The two piston air cylinders are fixedly arranged in a vertical direction far away from a handle of a hydraulic station power switch and are in articulated connection with piston connecting rods. When an air source of the end of the tong receiving and sending air cylinder is started to push the hydraulic and pneumatic tong to a wellhead to work, compressed air enters the right ends of the two piston air cylinders through the started one-way pneumatic switches to push the two piston air cylinders to move to the left, the piston connecting rods pull the handle of the hydraulic station power switch to move to a started direction, and the hydraulic station power switch is turned on. In the same way, when the hydraulic and pneumatic tong is stopped, the hydraulic station power switch is turned off. The hydraulic and pneumatic tong does not have invalid operation within a less-frequently using period, the abrasion and energy consumption of each parts of a hydraulic station are reduced, the environmental pollution is reduced, and the service life of the hydraulic and pneumatic tong is prolonged.
Description
Technical field
The present invention relates to the automatic startup in petroleum drilling workover fluid gas tong uses and stop.
Background technique
Petroleum drilling well workover liquid gas tong in making a trip, expand reaming, fast drilling use relatively more frequent, use interval time shorter, the slow well section of rate of penetration make up a joint less or some accident or complex process in the use of liquid gas tong just long interval time.But the post workman because being busy with other work, has just neglected shutting down when liquid gas tong does not use for a long time in using liquid gas tong process, make its in the long-time obsolete time all the time in operating condition.This had both aggravated the wearing and tearing of liquid gas tong hydraulic station, oil hydraulic pump, hydraulic pipe line, had also wasted the energy loss of its 35-55KW, both be unfavorable for extension device service time, more the pollution that causes to environment while being unfavorable for energy loss.
Summary of the invention
Also make its wasting phenomena in operating condition for the current ubiquitous liquid gas tong in scene in long-time no situation, purpose of the present invention has aimed to provide a kind of liquid gas tong automatic start-stop device, stops equipment attrition and energy waste that lost motion causes.Starting the source of the gas that advances fluid cylinder that liquid gas tong is pushed to after well head work, the work of stop solution gas tong regain while advancing fluid cylinder that liquid gas tong is removed to well head when this liquid gas tong automatic start-stop device adopts with liquid gas tong comes the automatic start-stop principle of synchronization control liquid gas tong hydraulic station power switch to realize the synchronous automatic start-stop of liquid gas tong.
The objective of the invention is to complete like this:
A kind of liquid gas tong automatic start-stop device is mainly by sending and receiving pincers cylinder, send the pincers air pipe, receive the pincers air pipe, unidirectional air cock, unidirectional air cock, two piston-cylinders, piston rod, hydraulic station power switch handle forms, sending on the pincers air pipe of sending and receiving pincers cylinder is parallel with unidirectional air cock, with gas pipeline, with the right inlet end of two piston-cylinders, be connected, receive on the pincers air pipe and be parallel with unidirectional air cock, with gas pipeline, with the left inlet end of two piston-cylinders, be connected, two piston-cylinders are fixed on the Vertical direction apart from hydraulic station power switch handle, one end of piston rod and the tailpiece of the piston rod chain connection of two piston-cylinders, the other end of piston rod and hydraulic station power switch handle chain connection.
The beneficial effect of advantage of the present invention and generation is:
1, the present invention has source of the gas now to carry out control circuit at the scene, and assembling is simple, cost is low, has advantages of generally and uses.
Synchronous start stop apparatus when 2, the present invention uses because of employing liquid gas tong, reduced liquid gas tong long-time equipment attrition, energy loss and environmental pollution that the used time lost motion does not cause, extended the working life of all corollary equipments of liquid gas tong hydraulic station.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of liquid gas tong automatic start-stop device is mainly by sending and receiving pincers cylinder 1, send pincers air pipe 2, receive pincers air pipe 3, unidirectional air cock 4, unidirectional air cock 5, two piston-cylinders 6, piston rod 7, hydraulic station power switch handle 8 forms, sending on pincers air pipe 2 of sending and receiving pincers cylinder 1 is parallel with unidirectional air cock 4, with gas pipeline, with the right inlet end of two piston-cylinders 6, be connected, receive on pincers air pipe 3 and be parallel with unidirectional air cock 5, with gas pipeline, with the left inlet end of two piston-cylinders 6, be connected, two piston-cylinders 6 are fixed on the Vertical direction apart from hydraulic station power switch handle 8, one end of piston rod 7 and the tailpiece of the piston rod chain connection of two piston-cylinders 6, the other end of piston rod 6 and hydraulic station power switch handle 7 chain connections.
The handle of unidirectional air cock 3 and unidirectional air cock 4 is removed to the position of opening normally creeping into etc. while frequently not using liquid gas tong, when the source of the gas that uses liquid gas tong to open sending and receiving pincers cylinder is pushed liquid gas tong to well head work, the pressurized air that promotes sending and receiving pincers cylinder 1 lead up to send pincers air pipe 2 enter sending and receiving pincers cylinder send the pincers end to promote liquid gas tong to move to well head, another road enters the right-hand member of two piston-cylinders 6 by unidirectional air cock 4, promoting two piston-cylinders 6 is moved to the left, piston rod 7 pulls hydraulic station power switch handle 8 to move to the direction of opening, the hydraulic station power switch is opened, hydraulic station and sending and receiving pincers cylinder is almost synchronizeed startup.When the end-of-job of liquid gas tong at well head, when the source of the gas of sending and receiving pincers cylinder is removed the well head working position to liquid gas tong, the pressurized air of regaining sending and receiving pincers cylinder 1 is leaded up to and is received the receipts pincers end that pincers air pipe 3 enters sending and receiving pincers cylinder and pull liquid gas tong to remove well head, another road enters the left end of two piston-cylinders 6 by unidirectional air cock 5, promoting two piston-cylinders 6 moves right, piston rod 7 promotes hydraulic station power switch handle 8 and moves to the direction of closing, and the hydraulic station power switch is closed.Guarantee that liquid gas tong be not there is no lost motion in the frequent spreadable life, reduce wearing and tearing and the energy consumption of its hydraulic station all parts, environmental contamination reduction, the working life of prolongation liquid gas tong.
Make a trip etc. frequent use liquid gas tong during, the handle of unidirectional air cock 3 and unidirectional air cock 4 is manually removed to the position to pass, liquid gas tong just can automatic start-stop, and the moment while reducing the frequent start-stop of hydraulic station power supply starts the infringement that load causes each contact of circuit and generator.
