Description
Technical field
The utility model relates to a kind of winch that is applied to petroleum drilling and mining, specifically, relates to a kind of single shaft and directly drives electric winch.
Background technology
Now; usually can use winch during petroleum drilling and mining; winch commonly used generally adopts asynchronous dynamo through helical wheel deceleration case drive roller shaft; main brake generally adopts the hydraulic disk brake; like this structure is set so that the monnolithic case of winch is larger; complexity is installed, is inconvenient to use, it is required for people therefore to invent a kind of Novel winch that can address this problem.
The utility model content
The purpose of this utility model is to provide a kind of single shaft directly to drive electric winch, and it is larger mainly to solve the existing winch profile that exists in the prior art, complexity is installed, the problem of being inconvenient to use.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Single shaft directly drives electric winch, comprise the first winch frame and the second winch frame that link to each other by pipe link, also comprise and being arranged between the first winch frame and the second winch frame, and the winch drum shaft that links to each other with the two respectively, described the first winch frame and the second winch frame opposing to the side also be respectively equipped with the brake gear that links to each other with winch drum shaft and be provided with the permagnetic synchronous motor of center shaft.
Specifically, the center shaft of described permagnetic synchronous motor is connected with an end of winch drum shaft by expansion sleeve, and this permagnetic synchronous motor also is fixed on its nearest winch frame; Described brake gear comprises the braking tong holder that brake clamp and brake disc are installed, and described brake disc is connected with winch drum shaft one end key, and is fixed on its nearest winch frame.
Consider the stability of connection, the two ends of described winch drum shaft are provided with bearing seat, and the two ends of winch drum shaft link to each other with nearest winch frame by bearing seat respectively.
Consider the convenience in the practical application, described pipe link is positioned at the upper end of the first winch frame and the second winch frame.
Further, the bottom of described the first winch frame and the second winch frame also is provided with supporting seat, and braking tong holder and permagnetic synchronous motor all are positioned on this supporting seat.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model adopts permagnetic synchronous motor to replace AC variable frequency asynchronous motor acceleration and deceleration case in the past to drive winch, saved drop-gear box, manufacturing and maintenance cost have been saved thus, the permagnetic synchronous motor volume is less simultaneously, energy consumption is lower, so that the integral structure of winch is more simple compact, and be easy to install.
(2) in the utility model, winch brake adopts the gas control dish to stop, can realize simultaneously service braking and safety arrestment, and do not need special hydraulic efficiency pressure system, only need the source of the gas of access rig just can realize, and do not have oil leaking pollution, such setting has namely reduced the complexity of operation, also eliminate environmental pollution, had very high practical value.
(3) the utility model adopts expansion sleeve connection winch cylinder and permagnetic synchronous motor, has reduced the requirement to setting accuracy, has fully taken into account the simplicity in the practical application.
(4) in the utility model, also be provided with the supporting seat that supports each parts, and also be provided with the pulley that is recoverable to below supporting seat, the utility model structure is more stable in such being arranged so that, and conveniently moving.
