Description
Technical field
The utility model relates to a kind of gate sync detection device; Particularly a kind of straight touch gate sync detection device; The detection of running stability when being mainly used in gate opening/closing in the Hydraulic and Hydro-Power Engineering is specially adapted in two suspension centre hydraulic headstock gear, especially the arc door headstock gears.
Background technology
The gate sync detection device is as an auxiliary device of opening and closing device; It detects performance and functional reliability; Accuracy to control of the running stability of two Hanging Point Gate and opening and closing device synchro control is most important; Concerning the gate of hinge flood discharge system, can obtain correct control signal, also will directly influence the normal keying operation of gate.Because the synchronous detection to large-scale gate all was the stroke detection acquisition indirectly after changing through headstock gear in the past; Can not directly react the working condition of gate in gate slot; Therefore; After considering the error of conversion generation, not only the precision to the stroke detection element proposes higher requirement, and the testing result reliability is not high.
Summary of the invention
The technical matters that the utility model will solve is: overcome deficiency of the prior art and provide a kind of environmental disturbances ability simple and compact for structure, easy for installation, anti-strong, can directly react the working condition of gate in gate slot, the more straight touch gate sync detection device of testing result.
The technical scheme that the utility model adopted is: straight touch gate sync detection device; It is characterized in that: it comprises the support that is fixedly installed on the lock gate leaf; And through rotation axis and the hinged spiral arm of this support; This spiral arm free end through turning axle hinged closely contact with the gate slot track and can be in this track the free rolling roller, said rotation axis and turning axle all belong to floor plan perpendicular to gate flap, wherein coaxial installation is used to detect the angular encoder of its rotational angle on the rotation axis.
Said rotation axis overcoat torsion spring, these torsion spring two ends are fixedly connected with rotation axis with support respectively.
Said support is a hollow sealing body, and angular encoder and torsion spring all are arranged in base inner, and in the junction of support and rotation axis waterproof grommet is set.
Said base inner is separated into two cavitys, and said angular encoder is with in torsion spring lays respectively at above-mentioned two different cavitys.
The beneficial effect of the utility model is: the utility model fixedly mounts support on lock gate leaf; While hinged spiral arm that closely contacts with gate slot on support; Coaxial setting angle scrambler in this spiral arm rotating shaft; Utilize the spiral arm swing directly to measure the variable in distance between gate flap and the gate slot, and reflect through the rotational angle of the detected spiral arm rotating shaft of angular encoder, thus obtained synchronizing signal is directly reliable; The many factors such as manufacturing, installation eliminated are to influence that operating gate produced; Make and detect data and directly reflect the operation conditions of gate in gate slot, the transformed error of avoiding various in the past indirect detection to certainly lead to has guaranteed the accuracy and the reliability of testing result; In addition, the utility model is simple and compact for structure, easy for installation, cost is low.

Embodiment
Like Fig. 1, shown in Figure 2; Present embodiment comprises the support 2 (being a hollow sealing body) that is fixedly installed on the lock gate leaf 1; Perforate and rotation axis 3 of rotating installation on this support 2; Said support 2 is provided with waterproof grommet 10 with the junction of rotation axis 3, can prevent effectively that sealing gets into support 2 inside, realizes anticorrosion, moistureproof simultaneously; Said rotation axis 3 one ends extend vertically arranged with it spiral arms 4 of support 2 outside also fixed connections (adopting key to connect), thereby realize the hinged of support 2 and spiral arm 4; The free end of said spiral arm 4 is through turning axle 5 hinged rollers 6, and this roller closely contacts with gate slot 9 tracks and can in this track, freely roll around turning axle 5; Said rotation axis 3 all belongs to floor plan perpendicular to gate flap 1 with turning axle 5; Wherein coaxial installation is used to detect the angular encoder 7 of its rotational angle on the rotation axis 3; In this example; Angular encoder 7 is fixedly installed on the rotation axis 3 away from spiral arm 4 one ends, said rotation axis 3 middle part overcoat torsion springs 8 (between spiral arm and angular encoder), and these torsion spring two ends are fixedly connected with rotation axis 3 with support 2 respectively; For the assurance device operate as normal, increase the service life, this example all is arranged in angular encoder 7 and torsion spring 8 in support 2 internal cavities.
As shown in Figure 3; Said support 2 comprises the machine base body 2-1 of both ends open; And the upper cover plate 2-2 and the lower cover 2-3 that are tightly connected with both ends open respectively, wherein be shaped on the median septum 2-4 that is parallel to upper cover plate 2-2 and lower cover 2-3 in the machine base body 2-1, whole seal chamber is separated into two independently cavitys; Angular encoder 7 and torsion spring 8 are laid respectively in above-mentioned two different cavitys, be independent of each other; In addition; Because rotation axis 3 passes upper cover plate 2-2 and median septum 2-4 (only in the junction of rotation axis and upper cover plate waterproof grommet being set) simultaneously; Make to be connected more stablely between rotation axis 3 and the support 2 that guaranteed the stability that rotation axis 3 rotates, it is constant that its pivot center is remained.
As shown in Figure 4; In the practical application, present embodiment is installed on the top or the bottom of gate flap 1 both sides, wherein support 2 is fixedly installed on the gate flap 1; Simultaneously spiral arm 4 with rotation axis 3 be the center laterally (towards gate slot one side) upwarp riding on the gate slot 9 of certain angle; This moment, torsion spring 8 received twisting strain, and spiral arm 4 makes that being positioned at its free-ended roller 6 closely contacts with gate slot 9 tracks under the twisting force of himself gravity and torsion spring 8; When deflection took place lock gate leaf 1, the distance between gate flap 1 and the gate slot 9 changed, and spiral arm 4 changes deflection angle, and reflects through the rotational angle of angular encoder 7 detected rotation axiss 3; The prior job information of presetting angle scrambler 7 when spiral arm 4 rotational angles during in its normal operation region, shows that the gate opening/closing operation is normal, and oil cylinder need not adjusted operation synchronously; When spiral arm 4 rotational angles exceed normal operation region, show that the gate deflection has exceeded deviation range, driving hydraulic system synchronization loop carries out oil cylinder and adjusts operation synchronously, reaches the purpose that gate flap 1 can steadily open and close operation.
Present embodiment separates stroke detection, demonstration with synchronous corrective control signal source, adopt digital quantity signal, and reliability is greatly improved, and is specially adapted to the synchronous deviation correction control system of closed loop of extended-top type arc door.
