Abstract
The utility model discloses a high-precision long-distance hydraulic gate opening instrument. The instrument comprises a rope accommodation mechanism. The rope accommodation mechanism is composed of a driving motor and a reel; the reel is wound by a wire rope; the instrument further comprises a measuring mechanism; the measuring mechanism is composed of a measuring roller and a photoelectric encoder; the rope outlet end of the wire rope passes through the measuring roller of the measuring mechanism; a photoelectric limit switch for limiting the position of the wire rope is arranged between the measuring mechanism and the rope accommodation mechanism; and the wire rope is also provided with a weight for tensing the wire rope. Compared to a conventional measuring instrument, the high-precision long-distance hydraulic gate opening instrument has the following advantages: the measuring distance is long and can be theoretically infinite; the measuring precision is high, is free from the influences of the reel and the winding of the wire rope and can be controlled within 1 mm; and the measuring mechanism is independent, the rope extending distance can be directly measured, and the influence caused by uneven winding of the wire rope to the measuring precision is overcome.
Description
Technical field
The utility model relates to a kind of hydraulic gate aperture instrument, relates in particular to a kind of high precision length apart from hydraulic gate aperture instrument.
Background technology
Tradition hydraulic gate aperture instrument, adopts wirerope-winding reel mode, measures by photoelectric encoder the number of turns and the angle that reel rotates, and carries out product with drum diameter, converts the distance that wire rope moves horizontally to.At present, on hydraulic gate, utilize more.Because the appearance rope amount of reel is limited, cause opening self-detective instrument measuring distance limited, measurement range is generally in 16m; Moreover reel diameter changes after multiple wraps, measure the rope stretching length that volume cake can not directly reflect wire rope, therefore can not ensure the measuring accuracy under long distance.In the measurement range of 16m, measuring error is substantially in 10mm left and right.
In Process of Hydropower Plant Construction, the keying lift of the even permanent gate of some emergency gates even arrives 60m more than having reached 20m at present.Such as, be 60m to the keying lift of power station, family dam 1～5# diversion outlet closuring gate, in order to ensure reliability and the security of gate opening, must accurately measure gatage, need to design novel opening self-detective instrument for this reason.
Utility model content
The problem existing for above-mentioned prior art, the utility model object has been to provide a kind of high precision length that has solved above problem apart from hydraulic gate aperture instrument.
The technical solution of the utility model is: a kind of high precision length is apart from hydraulic gate aperture instrument, comprise Rong Sheng mechanism, described Rong Sheng mechanism is made up of drive motor and reel, on described reel, be wound with wire rope, also comprise measuring mechanism, described measuring mechanism is by measuring roller and photoelectric encoder forms, the rope-out end of described wire rope is through the measurement roller of measuring mechanism, described measuring mechanism and Rong Sheng mechanism between be provided with restriction wire rope position photoelectric limit switch, on described wire rope, be also provided with the weight of its tensioning;
As preferably, also comprise frame, described Rong Sheng mechanism, measuring mechanism, photoelectric limit switch are fixedly connected with frame respectively;
As preferably, described drive motor and reel are in transmission connection;
As preferably, described measurement roller is positioned in rotating shaft, and described photoelectric encoder is coaxial with rotating shaft;
As preferably, described measurement roller is two, and arranges by front and back;
As preferably, described photoelectric limit switch has two to be respectively photoelectric limit switch and lower photoelectric limit switch;
As preferably, described measurement roller is provided with the groove matching with wire rope.
The beneficial effects of the utility model are:
(1) measuring distance is long, and it is unlimited to accomplish in theory, and this device is 65m at present;
(2) measuring accuracy is high, is not subject to the impact of reel, wirerope-winding, and precision is controlled in 1mm;
(3) measuring mechanism independently, directly the rope stretching distance of measuring steel wire rope, overcomes the impact that wirerope-winding inequality causes measuring accuracy.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1. photoelectric encoder; 2. drive motor; 3. reel; 4. frame; 5. wire rope; 6. weight; 7. measure roller; 8. photoelectric limit switch.
Embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of high precision length is apart from hydraulic gate aperture instrument as shown in Figure 1, comprise Rong Sheng mechanism, described Rong Sheng mechanism is made up of drive motor 2 and reel 3, described drive motor 2 is in transmission connection with reel 3, on described reel 3, be wound with wire rope 5, also comprise measuring mechanism, described measuring mechanism is by measuring roller 7 and photoelectric encoder 1 forms, also comprise frame 4, described Rong Sheng mechanism, measuring mechanism, photoelectric limit switch 8 is fixedly connected with frame 4 respectively, the rope-out end of described wire rope 5 is through the measurement roller 7 of measuring mechanism, described measurement roller 7 is provided with the groove matching with wire rope 5, facilitate wire rope 5 cablings, described measurement roller 7 is two, and arrange by front and back, described measurement roller 7 is positioned in rotating shaft, described photoelectric encoder 1 is coaxial with rotating shaft, conveniently to wire rope, 5 outlets are measured, described measuring mechanism and Rong Sheng mechanism between be provided with restriction wire rope 5 positions photoelectric limit switch 8, described photoelectric limit switch 8 has two to be respectively photoelectric limit switch and lower photoelectric limit switch,
This Novel gate aperture instrument, is mainly divided into two large divisions, and the one, measuring mechanism, the 2nd, the Rong Sheng mechanism that translator drives.By drive motor 2 and photoelectric limit switch 8, measuring steel wire rope 5 is evenly arranged in above reel 3, and passes through weight 6 by wire rope 5 tensioning all the time.Measuring mechanism is no longer measured reel 3 as traditional approach, but directly rope-out end is measured.
This arrangement, can infinitely increase Rong Shengliang in theory, and therefore measuring stroke, can to reach 65m even more.Meanwhile, drive Rong Sheng mechanism by motor, wire rope 5 is wrapped in above reel 3; Rope is measured in weight 6 tensionings, has eliminated the disturbance to measuring junction when wire rope 5 is wound around, and ensures measuring accuracy.Meanwhile, independently measuring mechanism, the directly rope stretching distance of measuring steel wire rope 5, overcomes wire rope 5 and is wound around the uneven impact that measuring accuracy is caused.
The long range gate aperture instrument of a kind of novel high-precision that the utility model provides, has advantages of that measuring distance is long, measuring accuracy is high, has stronger practicality.
Above high precision length provided by the utility model is carried out to detailed introduction apart from hydraulic gate aperture instrument, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, to be possible to change of the present utility model and improvement, and can not exceed design and the scope of accessory claim defined, in sum, this description should not be construed as restriction of the present utility model.
