Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, the present invention provides an operation locking control for the upper and lower doors of the navigation hole of the axle river gate: including pier 1, support 2, control lever 3, go up door 4, lower door 5, waterproofing steel plate 6 and stagnant water rubber 7, pier 1 top is provided with support 2, pier 1 all is provided with nine, be provided with the spout between, and go up the embedding of door 4 in this spout, it fixes with waterproofing steel plate 6 to lock through the bolt to go up the inside bottom of door 4, lower door 5 embedding is inside last door 4, lower door 5 top is the P shape, and this P shape bottom bonds has stagnant water rubber 7, stagnant water rubber 7 bottom is laminated with waterproofing steel plate 6, lower door 5 embedding is inside last door 4, support 2 bottom is through control lever 3 respectively with last door 4 and lower door 5 carry out bolted connection.

Wherein the top end of the lower door 5 is P-shaped, and the protruding side is protruded forward, which is beneficial to seal the space between the lower door 5 and the upper door 4 to form a water gate.

The upper door leaf 4 is composed of a front clamping plate and a rear clamping plate, the clamping plate at the front end is L-shaped, and the bottom end of the front clamping plate protrudes backwards, so that the front clamping plate can be attached to the P-shaped top end of the lower door leaf 5 conveniently, and a water gate is formed.

The thickness of the water-stop rubber 7 is more than five centimeters, which is beneficial to sealing the joint of the lower door 5 and the waterproof steel plate 6, namely sealing between the upper door 4 and the lower door 5.

The thickness of the waterproof steel plates 6 is larger than five centimeters, and the waterproof steel plates are beneficial to supporting the P-shaped head of the lower door leaf 5.

The working principle is as follows: under the normal working condition, when the gate is opened and the lower door leaf 5 runs to the top dead center position, the limit switch 1SP1 is switched off, at the moment, the coil of the intermediate relay 1KJ1 is powered off, the normally open point of the intermediate relay 1KJ1 is switched off, and the lower door leaf 5 stops running upwards; the intermediate relay 1KJ1 is closed at a normally closed point, and the upper door 4 can be moved upward (forward rotation) by pressing the upper door 4 raising button 2SB 1; the lower door 5 control circuit and the upper door 4 control circuit, when the gate is closed and the upper door 4 moves to the bottom dead center position, the limit switch 2SP2 is turned off, and the coil of the intermediate relay 2KJ2 is powered off: the normally open point of the intermediate relay 2KJ2 is turned off, and the downward operation of the upper door leaf 4 is stopped; the intermediate relay 2KJ2 is closed at a normally closed point, and the lower door 5 can be operated downward (reversed) by pressing the lower door 5 lowering button 1SB 2. Thereby realizing the operation sequence of the upper and lower door leaves 5: when the gate is opened, the lower door 5 is opened first, and then the upper door 4 is opened; when the gate is closed, the door leaf 4 is closed first, then the door leaf 5 is closed, under the maintenance working condition (when the limit switch is not operated, another locked gate is operated), the normally closed point of the intermediate relay with locking function is connected in parallel with a button SB to be unlocked (namely the part of the irregular coil in the lower diagram), and the operation can be realizedThe upper and lower door leaves 5 now operate the unlocking operation. The upper door 4 normal rotation button 2SB1 is locked with the lower door 5 upper limit 1SP1 (normally closed point 1KJ1 in the figure), that is: when the lower door 5 reaches the top dead center, 1SP1 (top dead center limit switch of the lower door 5) is turned off, and the upper door 4 is lifted (rotated forward) by pressing the door opening button 2SB1 of the upper door 4; before the lower door 5 does not reach the upper limit, 1SP1 is closed, the coil of the intermediate relay 1KJ1 is electrified, the normally closed point of the intermediate relay 1KJ1 is opened, at the moment, the door opening button 2SB1 of the upper door 4 is pressed, the circuit is not closed, and the upper door 4 can not realize the ascending operation; however, in some working conditions, the lower door 5 does not reach the upper limit, and at this time, the upper door 4 needs to be opened, the unlocking button 2SB can be used for unlocking, and the upper door 4 can be lifted and operated at any time as long as the two buttons 2SB1 and 2SB are pressed simultaneously, and the door closing button 1SB2 of the lower door 5 is locked with the lower limit 2SP2 of the upper door 4, namely: when the upper door 4 reaches the bottom dead center, 2SP2 (the top door 4 bottom dead center limit switch) is turned off, the closing button 1SB2 of the door 5 is pressed, and the lower door 5 descends (rotates reversely); before the upper door 4 reaches the lower limit, 2SP2 is closed, and the door 5 closing button 1SB2 is pressed, so that the circuit is not closed and the lower door 5 cannot perform the lowering operation. However, in abnormal conditions, the upper door 4 does not reach the lower limit position, and the lower door 5 needs to be closed, so that the unlocking button 1SB can be used_{Solution (II)}As long as 1SB is pressed simultaneously₂And 1SB_{Solution (II)}The lower door leaf 5 can descend at any time by the two buttons, and the upper door leaf 5 and the lower door leaf can run interlocking operation under normal working conditions, so that the damage of a gate component caused by misoperation can be avoided; and an unlocking operation in the case that the locking is not released in the case of maintenance.
