Description

Plane steel gate bottom-touching detection device

Technical Field

The utility model belongs to the technical field of thermal power plant, nuclear power station plane steel gate equipment, concretely relates to plane steel gate touches end detection device.

Background

The steel gate is one of important devices for opening and closing the water passing hole of the hydraulic building, has the functions of completely or partially closing the water passing hole to adjust the water levels and the flow rates of upstream and downstream, intercepting water flow to obtain flood control irrigation, guiding water to generate electricity, overhauling the water passing hole, and removing impurities in water such as silt, ice blocks and the like, and can be widely applied to hydraulic buildings such as thermal power plants, hydropower stations, pump stations, water taking and drainage systems, water conservancy drainage and irrigation, channel systems and the like.

In the prior art, in the process of descending and placing the steel gate, after an operator judges that the steel gate goes to the bottom through experience, the grabbing beam of the steel gate is separated from the steel gate body, and when the operator finds that the steel gate body is accidentally clamped and is not correctly placed at the bottom of a pool, the grabbing beam of the steel gate is separated, so that the steel gate body cannot be quickly lifted and cannot be re-installed in place. Therefore, it is highly desirable to develop a mechanism that can accurately determine whether the gate is installed in place, and that preferably ensures that the grab beam does not disengage from the gate when the gate is accidentally stuck.

Disclosure of Invention

The application provides a detection device at bottom of plane steel gate, this equipment not only can accurately judge the gate and install target in place, can also ensure that the gate is grabbed the roof beam and can not break away from with the gate when being blocked by accident.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a plane steel gate bottom-touching detection device comprises a hinged support, a rotating arm, a sliding rod, a sliding seat, a first rotating shaft, a second rotating shaft and a touch rod; the hinged support is fixedly arranged on an upper cross beam web plate of the gate through bolts, the hinged support is connected with the rotating arm and the sliding rod through the first rotating shaft, the rotating arm and the sliding rod are fixed, the included angle is 90 degrees, the sliding seat capable of sliding along the sliding rod is sleeved on the sliding rod, the lower end of the sliding seat is connected with the contact rod through the second rotating shaft, and the contact rod vertically penetrates through a gate body and extends downwards to touch the head of the probing end.

Further, the rotating arm and the sliding rod are integrally formed.

Furthermore, the rocking arm is the trapezium structure, and the upper end of rocking arm is equipped with supports the end, and the rocking arm vertical direction is provided with the strengthening rib.

The utility model has the advantages that:

the utility model discloses the feeler lever touches the end earlier the back gate door body can continue to descend until touching the end, and the feeler lever moves upward relative to the gate door body, because the free bearing is fixed on the entablature web plate of gate, so the slide can drive the slide bar to lift up, and the rocking arm that fixes 90 degrees with the slide arm rotates, and the rocking arm breaks away from with the gate grab beam that pushes up on its upper portion promptly, and the demonstration gate door body touches the end completely at this moment, and the latch mechanism of grabbing the beam just can with the gate door body unblock, grab beam can break away from; the utility model discloses rational in infrastructure, simple, the flexible operation can effectual protection plane steel gate's life, reduces the overhaul period of equipment, makes the life of equipment complete machine improve greatly.

in the figure, 1-hinged support, 2-rotating arm, 3-sliding rod, 4-sliding seat, 5-first rotating shaft, 6-second rotating shaft, 7-feeler lever, 8-upper cross beam web plate of gate, 9-gate body and 10-gate grabbing beam.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances.

Referring to fig. 1, the device for detecting the bottom contact of a planar steel gate comprises a hinged support 1, a rotating arm 2, a sliding rod 3, a sliding seat 4, a first rotating shaft 5, a second rotating shaft 6 and a contact rod 7; the hinged support 1 is fixedly arranged on a gate upper beam web plate 8 through bolts, the hinged support 1 is connected with a rotating arm 2 and a sliding rod 3 through a first rotating shaft 5, the rotating arm 2 and the sliding rod 3 are integrally formed, the included angle is 90 degrees, the rotating arm 2 is of a trapezoidal structure, the upper end of the rotating arm 2 is provided with a supporting end, the rotating arm 2 is supported between a gate grab beam 10 and the gate upper beam web plate 8 under the state that a gate body is not descended (the detection device is ready), the supporting end of the rotating arm is abutted to the lower end face of the gate grab beam 10, and reinforcing ribs are arranged in the vertical direction of the rotating arm 2 in order to increase the; slide 4 that can follow the slide is established to the cover on the slide bar 4, and slide 4 lower extreme passes through second pivot 6 and connects feeler lever 7, and feeler lever 7 vertically wears to establish gate door body 9 and stretches out downwards and touch and visit the end head portion.
