Abstract
The utility model discloses an automatic escape speed reducer for a workover rig racking platform and belongs to the technical field of workover treatment. A shell fixes a roller central shaft and a centrifugal speed governor; the output shaft of the centrifugal speed governor is connected to the shell through a first bearing in a supporting way; a pinion is connected to the output shaft and is meshed with a gear wheel; the gear wheel is connected with a roller through a one-way bearing; the roller central shaft is connected to the inner circle of the roller through a second bearing; the roller is connected to the other end of the roller central shaft through a third bearing; a clockwork spring is connected to the outer circumference of the roller; and a steel wire rope is wound on the roller. By using the automatic escape speed reducer for the workover rig racking platform, the glide time is shortened; the speed is automatically adjusted from rapid speed to slow speed until stop; after personnel leave, automatic and rapid return is realized; and only one rope is needed, the mounting labor intensity during the moving process is alleviated.
Description
Technical field
The utility model relates to a kind of workover rig quadruple board platform escape automatic retarding machine, belongs to the workover treatment technical field.
Background technology
In the oil-gas field downhole operation construction, workover rig is as the workover rig extensive use, and quadruple board platform is the important component part of workover rig, and personnel withdraw the safety that directly has influence on personnel under its emergency.In process of production, the quadruple board platform staff can not guarantee personnel's safety because gliding speed is too fast in fleeing from the quadruple board platform process, increased the personal security risk.Usually speed is crossed slowly when accident occurs personnel and is withdrawn untimelyly when the quadruple board platform staff uses traditional device of runing away, and installs complicatedly, and rope is too much.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of workover rig quadruple board platform escape automatic retarding machine, can finish withdrawing of quadruple board platform personnel within the several seconds, has greatly shortened the time that emergency personnel is withdrawn.
A kind of workover rig quadruple board platform escape automatic retarding machine, shell resting barrel central axis and centrifugal speed limiter, the output shaft of centrifugal speed limiter passes through the clutch shaft bearing support and connection at shell, output shaft connects pinion, the pinion gear wheel, and gear wheel connects cylinder by unilateral bearing, the inner circle of cylinder connects drum central axis by the second bearing, the other end of drum central axis connects cylinder by the 3rd bearing, and the excircle of cylinder connects clockwork spring, and wirerope-winding is on cylinder.
Wirerope-winding drives gear wheel by unilateral bearing on cylinder, the large gear turn the small gear, what pinion connected is a centrifugal speed limiter, that is to say when wire rope pulls out the unilateral bearing drive gear wheel that works, gear wheel drives pinion again, and pinion drives centrifugal speed limiter can speed limit, and clockwork spring is more and more tighter simultaneously, clockwork spring drives cylinder wraparound wire rope when going back, and the unilateral bearing counter gear is not moved and can be accomplished automatic speed-limiting and returning quickly.
Because the wire rope on the cylinder all is wrapped on the cylinder when resetting, therefore when the diameter of cylinder is namely maximum, the fewer diameter of cylinder of wire rope is also just less thereupon, in the rotation of wire rope downdraw process intermediate roll also just from slow to fast, but because the speed limit effect of centrifugal speed limiter, wire rope is just pulled out also thereupon from fast to slow, and clockwork spring is also in that past to go out the resistance that cylinder receives larger to tight wire rope by pine in this process.Stop to the limit at last.When no longer including external force, wire rope pulls out.Unilateral bearing effect gear wheel between clockwork spring drive cylinder and the gear wheel no longer turns thereupon, and the wraparound wire rope is finished a work period fast,
The beneficial effect of advantage of the present utility model and generation is:
Traditional device rope of runing away is too many and be at the uniform velocity to glide in the middle of using, and it is excessive to the impact force on ground to adjust too fast personnel, if adjusted slow and prolonged personnel's departure time.The utility model has not only shortened the downslide time but also has automatically regulated the speed from fast to slow at last to stopping, and waits personnel to leave rear automatic returning quickly.And only need a rope.Alleviated in the removal of home process labour intensity has been installed.
Description of drawings
When considered in conjunction with the accompanying drawings, by the following detailed description of reference, can more completely understand better the utility model and learn easily wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, consist of a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model, such as figure wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of workover rig quadruple board platform escape automatic retarding machine, shell 2 resting barrel central axiss 5 and centrifugal speed limiter 3, the output shaft 13 of centrifugal speed limiter 3 passes through clutch shaft bearing 4 support and connection at shell 2, output shaft 13 connects pinion 1, pinion 1 engagement gear wheel 7, gear wheel 7 connects cylinder 9 by unilateral bearing 12, the inner circle of cylinder 9 connects drum central axis 5 by the second bearing 6, the other end of drum central axis 5 connects cylinder 9 by the 3rd bearing 8, the excircle of cylinder 9 connects clockwork spring 11, and wire rope 10 is wrapped on the cylinder 9.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
