Detailed Description

The technical scheme of the utility model is clearly and completely described below with reference to the accompanying drawings and the specific embodiments. The specific matters listed in the following examples are not limited to the technical features necessary for solving the technical problems of the technical solutions described in the claims. Meanwhile, the list is only a part of embodiments of the present utility model, but not all embodiments.

FIG. 1 is a schematic view of one embodiment of the bottom shaft gate support locking mechanism of the present utility model. The door plate 1, the bottom shaft 2, the swing arm 3 and the gate opening and closing mechanism 4 are the structure of the bottom shaft gate. Wherein, the bottom shaft 2 is fixed on the river course foundation 13 through the axle bed, and the door plant 1 is fixedly connected with the bottom shaft 2. The swing arm 3 is fixed at the end of the bottom shaft 2 and is positioned at the side surface of the door plate 1. The gate opening and closing mechanism 4 adopts a hydraulic oil cylinder, and a cylinder rod of the gate opening and closing mechanism is hinged with the swing arm 3 and is used for driving the bottom shaft 2 and the door plate 1 to rotate through the swing arm 3.

As shown in fig. 1, the support locking mechanism includes a support bar 5, one end of which is hinged to the swing arm 3, and the other end of which is attached to a support member 8 such as a support platform, and is movable on the support member 8. The support rod 5 extends in the swing direction of the swing arm 3, and as the swing arm 3 swings, the support rod 5 is driven to extend forward (right side in the drawing) or retract backward. A plurality of stop blocks 6 are arranged on the upper side of the support rod 5, and the stop blocks 6 are distributed at intervals along the length direction of the support rod 5. Above the support bar 5 there is a laterally arranged stop pin 9. The plurality of stop blocks 6 can pass through the position of the stop pin 9 along with the front and back extension of the support rod 5. When the stopper pin 9 is abutted to a position of one of the stoppers 6, it is possible to press against the support rod 5, restricting its movement, thereby locking the swing arm 3 and the door panel 1 at a predetermined angle. The cooperation of the stop pin 9 with the different stops 6 is controlled by a driving member 10.

In the embodiment shown in fig. 1, the driving member 10 employs a hydraulic cylinder, which is directly or indirectly connected to the stopper pin 9, for driving the stopper pin 9 to move up and down. When the stop pin 9 is driven to move upwards, the stop pin 9 is separated from the stop block 6 of the support rod 5, and the support rod 5 is not limited and can stretch back and forth. When the door plate 1 and the swing arm 3 rotate to a preset angle and the support rod 5 moves to a preset position along with the door plate, the driving part 10 controls the stop pin 9 to be fixed or move downwards, and the stop pin can be abutted against the stop block 6 at the corresponding position, so that the support locking function is realized. In this embodiment, the driving member 10 is provided above the stopper pin 9, and drives the stopper pin 9 by a link or the like. Likewise, the driving member 10 may be provided below to drive the stopper pin 9 through links disposed at both sides of the support rod 5.

Since it is only necessary to provide a supporting force for preventing the door panel 1 from tilting under normal conditions, as shown in fig. 1, the left side is the water supply direction, and the right side is the door panel 1 rotating and tilting direction. The stopper pin 9 only needs to restrict the movement of the support rod 5 to the right side to play a supporting locking role for the door panel 1. When the support bar 5 moves to the left, no restriction is required. As shown in fig. 3, the right side surface of the stopper 6 is a supporting surface abutting against the stopper pin 9, and on the left side surface opposite thereto, a guide rib 7 may be provided, and the top surface of the guide rib 7 is a slope extending obliquely from the surface of the support rod 5 to the top end of the stopper 6. An elastic structure is arranged in the driving mechanism 10 or the connecting structure between the driving mechanism 10 and the stop pin 9, so that the stop pin 9 can overcome the elastic force to be far away from the support rod 5 under the acting force of the guide rib plate 7. In the process of closing the gate, the driving part does not need to act, and the gate can be closed under the action of the guide rib plate 7 on the supporting rod 5.

In the embodiment not shown in the figures, the driving part 10 can also be arranged on the side of the support rod 5, and the driving stop pin 9 can be moved laterally, inserted into the stop 6 from the side of the support rod 5 or retracted and disengaged.

In another embodiment, not shown, the stops 6 may be spaced apart on the sides of the support bar 5. Correspondingly, the stop pin 9 is also arranged on one side of the support rod 5, and is driven by the driving component 10 to horizontally move from the side to abut against the stop block 6 or move up and down along the axis to contact with or separate from the stop block 6. The manner of closing the gate with the elastic structure and the guide rib 7 without actuation of the drive member is equally applicable to a structure in which the stopper 6 and the stopper pin 9 are provided on the side.

In another embodiment not shown in the drawings, a plurality of hole sites can be arranged in the middle of the supporting rod, the interval part between the hole sites is used as a stop block 6, the driving part drives the stop pin 9 to be inserted into or separated from the hole sites on the supporting rod, and the locking or unlocking of the supporting rod can be realized, so that the locking or unlocking of the moving position of the gate is realized.

As shown in fig. 2, in the embodiment in which the stopper pin 9 moves up and down, a positioning frame 11 is provided above the supporting member 8, and the positioning frame 11 has frame bodies on both sides of the supporting rod 5, on which guide grooves 12 are vertically provided. The stop pin 9 is arranged in the positioning frame 11, and two ends of the stop pin are respectively in sliding fit with the guide grooves 12 on two sides. On the one hand, plays a role in guiding the up-and-down movement of the stopper pin 9, and on the other hand, the stopper pin 9 is fixed in position in the horizontal direction to play a role in supporting the support rod 5.

Fig. 4 shows another embodiment of the present utility model. In this embodiment, the stop pin 9 is fixedly arranged, suspended transversely above the support rod 5. The supporting part 8 below the supporting rod 5 adopts a lifting structure. The support member 8 may be the driving end of the driving member 10 or may be a member connected to the driving end. The support rod 5 can be driven by the driving component to move up and down directly or indirectly. When the support bar 5 rotates downward, the stopper 6 provided at the upper side thereof can be disengaged from the stopper pin 9. After the support rod 5 moves upwards to rotate and lift, the stop block 6 arranged on the upper side of the support rod can be matched and abutted with the stop pin 9.

In the embodiment shown in fig. 1 and 2, the supporting rod 5 extends in the direction of rotating and falling the door panel 1, and the supporting rod 5 is propped against the stop pin 9 to play a supporting and locking role. It is expected that if the supporting rod 5 is extended in the direction of the rotation and lifting of the door panel 1, the stop pin 9 applies a pulling force to the supporting rod 5 through the stop block 6 of the supporting rod, so that the door panel 1 is prevented from toppling over, and a supporting and locking effect is achieved. In this way, the above-described stopper 6 arrangement of the support lever 5, the arrangement of the stopper pin 6, and the drive manner of both disengagement and contact are also applicable.

The above description of the specific embodiments is only for aiding in understanding the technical concept of the present utility model and its core idea, and although the technical solution has been described and illustrated using specific preferred embodiments, it should not be construed as limiting the present utility model itself. Workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit of the technology. Such modifications and substitutions are intended to be included within the scope of the present utility model.
