Abstract
The utility model provides a single gear transmission drilling machine winch and belongs to the technical field of oil exploitation. The drilling machine winch includes a single roller spindle and two high-power AC frequency converting motors. The two high-power AC frequency converting motors are arranged in axial symmetry and the single roller spindle is taken as the symmetry axis. And pinions installed on spindle noses of the high-power AC frequency converting motors engage with bull gears installed on the spindle nose of the single roller spindle. The spindle nose of one of the high-power AC frequency converting motors connects with a low-power AC frequency converting motor reducer through a clutch. The single gear transmission drilling machine winch in the utility model adopts a dynamic braking device of the AC frequency converting motor as a main brake to realize well drilling operations of a drilling machine such as tripping and the like; and adopts a hydraulic disc brake arranged on an end of the single roller spindle as an auxiliary brake to realize an automatic drilling function of a low-power motor. The single gear transmission drilling machine winch in the utility model adopts a single gear transmission method and has characteristics of high transmission efficiency, low noise, compact structure, small outer dimension and low weight, thereby satisfying requirements of normal well drilling operations of the drilling machine.
Description
Technical field
The utility model belongs to technical field of petroleum extraction, relates to a kind of petroleum drilling and mining lifting means, relates in particular to a kind of single gear transmission boring winch, can be used for not comprovincial oil production.
Background technology
Along with the development of alternating frequency conversion technique, the AC frequency conversion electric drilling machine arises at the historic moment in recent years, and winch just must be adapted to the characteristics of alternating frequency conversion technique as the core component of rig, has performance and high driving efficiency and economic serviceability reliably.At present, what generally use is secondary gear case transmission electrical drawworks and chain-driving electrical drawworks, the complex structure of the electrical drawworks of these two kinds of type of drive; Volume is big, and quality is big, and cost is high; Efficient is low, and inconvenient installation, brings a lot of inconvenience for normal well-digging operation.
The utility model content
The purpose of the utility model is the problem to existing secondary gear case transmission electrical drawworks and the existence of chain-driving electrical drawworks; A kind of driving efficiency height that just has is provided, and economic serviceability is strong, and noise is little; Compact conformation, little, the lightweight single gear transmission of oad boring winch.
The single gear transmission boring winch of the utility model comprises a single drum shaft, two high power AC adjustable frequency motors; Said two high power AC adjustable frequency motors are the axis symmetric arrangement with single drum shaft, and respectively through miniature gears that is installed in its spindle nose and the big gear wheel engagement that is installed in said single drum shaft spindle nose, realize the transmission of active force; Wherein the spindle nose of a high power AC adjustable frequency motor is connected with miniwatt alternating-current variable frequency motor retarder through power-transfer clutch, realizes small machine automatic bit feed function.
The utility model adopts alternating-current variable frequency motor resistance braking action to be the winch main brake.Being provided with hydraulic disc brake at an end of single drum shaft is assist brake.
The principle of work of the utility model: by two high speeds, wideband, high-performance ac variable-frequency electric motor active force is provided, respectively through direct drive list drum shaft after the one-level gear change; Adopt the AC frequency conversion vector control technology to control main motor and realize the rising of rig, drilling operation such as drilling tool down,, realize small machine automatic bit feed function through power-transfer clutch dislodging miniwatt alternating-current variable frequency motor retarder.
The relative prior art of the utility model has the following advantages:
1, the utility model winch structure is simple, and is in light weight, and oad is little, easy for installation, and integral module can be realized on-the-spot Fast Installation rapidly, satisfies normal well-digging operation.
2, the utility model adopts the single gear transmission, has higher driving efficiency, improves 10% than chain-driving electrical drawworks, improves 6% than secondary gear case transmission electrical drawworks, has improved drilling efficiency greatly, has practiced thrift drilling time.
3, the utility model adopts the high class gear transmission, has stable drive, noise is low, safeguards advantages such as simple, has very strong economic serviceability.
Description of drawings
Fig. 1 is the structure principle chart of the utility model.
The specific embodiment
Further specify below in conjunction with the structure and the transmission principle of accompanying drawing the utility model winch.
With reference to Fig. 1; A kind of boring winch of single gear transmission; Comprise a single drum shaft 3, two high power AC adjustable frequency motors 8; Two high power AC adjustable frequency motors (8) are the axis symmetric arrangement with single drum shaft (3), and respectively through 6 engagements of miniature gears 7 that is installed in high power AC adjustable frequency motor spindle nose and the big gear wheel that is installed in single drum shaft 3 spindle noses, realize the transmission of active force.The spindle nose of a high power AC adjustable frequency motor 8 is connected with miniwatt alternating-current variable frequency motor retarder 4 through power-transfer clutch 5 therein, realizes small machine automatic bit feed function.
This boring winch adopts AC frequency conversion vector control technology, is main brake with the alternating-current variable frequency motor resistance braking, realizes the drilling operations such as, time drilling tool of rig; With the hydraulic disc brake that is arranged on single drum shaft 3 one ends is assist brake 1, realizes small machine automatic bit feed function.
Claims (3)
1. the boring winch of a single gear transmission; Comprise a single drum shaft (3), two high power AC adjustable frequency motors (8); It is characterized in that: said two high power AC adjustable frequency motors (8) are the axis symmetric arrangement with single drum shaft (3), and respectively through miniature gears (7) that is installed in high power AC adjustable frequency motor spindle nose and big gear wheel (6) engagement that is installed in said single drum shaft (3) spindle nose; Wherein the spindle nose of a high power AC adjustable frequency motor (8) is connected with miniwatt alternating-current variable frequency motor retarder (4) through power-transfer clutch (5).
2. the boring winch of single gear transmission according to claim 1, it is characterized in that: an end of said single drum shaft (3) is provided with assist brake (1).
