Detailed Description
As shown in fig. 1 to 8, the present embodiment is a lock restricting device for a lock gate, including a base 1, a lock body 2, and a lock mechanism.
The locking body 2 is a T-shaped integrated structure consisting of a bolt 2-1, a locking connecting piece 2-2 and a bolt balancing piece 2-3, the bolt 2-1 and the bolt balancing piece 2-3 are coaxially arranged, and the axis of the locking connecting piece 2-2 is vertical to the axis of the bolt 2-1 and the locking connecting piece 2-2. The locking link 2-2 is used to balance the weight of the bolt 2-1 so that the centre of gravity of the locking body 2 is located on the axis of the locking link 2-2.
In this example, the locking body 2 is rotatably mounted on the base 1 via a locking shaft 3, the axis of which intersects the axis of the bolt 2-1 and the axis of the locking connector 2-2 and is perpendicular to the axis of the bolt 2-1 and the axis of the locking connector 2-2. When the locking body is not acted by external force (namely, the initial state), the locking connecting piece 2-2 on the locking body 2 is in a vertical state, and the bolt 2-1 is horizontal and exposed out of the machine base 1 (see fig. 5).
In the embodiment, the base 1 is provided with a bottom plate 1-3, two side plates 1-1 and a connecting plate 1-2 which are vertically fixed on the bottom plate 1-3, wherein the two side plates 1-1 are parallel to each other and are vertically connected to the same side of the connecting plate 1-2. The locking body 2 is arranged between the two side plates, the locking shaft 3 is horizontal, and two ends of the locking shaft are respectively connected to the side plates 1-1 at two sides.
In the embodiment, a vertical guide groove is arranged below the bolt balance piece 2-3 in an initial state, and the guide groove is formed by enclosing two side plates 1-1, a connecting plate 1-2 and a supporting plate 1-4 for connecting the two side plates 1-1. A locking block 7 capable of moving up and down along the guide groove is arranged in the guide groove, and an action mechanism capable of pushing the locking block 7 to move is arranged below the locking block 7.
In this example, the actuating mechanism has two rotating shafts 5 arranged in parallel, the rotating shafts 5 are horizontal, and both ends of the rotating shafts 5 are respectively rotatably connected to the connecting plate 1-2 and the supporting plate 1-4, wherein one rotating shaft 5 is exposed after passing through the connecting plate 1-2, and the rocker arm 4 is fixed on the exposed end. The two rotating shafts 5 are respectively provided with a cam 6, the upper edge of the cam 6 is provided with a section of tooth 6-1, the two cams 6 on the two rotating shafts 5 are symmetrically arranged and are mutually meshed and connected through the teeth 6-1 on the two rotating shafts, thereby realizing the synchronous and reverse rotation of the two cams 6.
In the embodiment, an arc groove 7-1 parallel to the rotating shaft 5 is formed on the lower end surface of the locking block 7 corresponding to the two cams 6 below the locking block.
In the embodiment, the locking limiting device for the gate is connected and installed on the concrete foundation on two sides of the gate 8 through foundation bolts, the locking limiting device for the gate is used for bearing the dead weight load of the gate 8, and the rotation and the limiting rotation of the locking body 2 realize the unlocking and locking operation of the gate 8.
The working principle of the embodiment is as follows:
in the initial state, the locking body 2 is controlled by the self-weight balance of its structure and is in a freely rotatable horizontal state.
When the gate 8 needs to be locked, the rocker arm 4 is rotated to the locking position, the two cams 6 are synchronously rotated, the convex surfaces of the two cams 6 are rotated to the vertical position from the horizontal position, the locking block 7 is pushed to ascend, the locking block 7 enters the rotating space of the locking body 2 to limit the rotation of the locking body 2, the bolt 2-1 of the locking body 2 bears the self-weight load of the gate 8 and is transmitted to the locking block 7 and the machine base 1 through the locking connecting piece 2-2 of the locking body 2, and the locking operation of the gate 8 is realized (see fig. 9). After the locking operation is finished, the rocker arm 4 is released, and at the moment, under the action of the arc groove 7-1 at the lower end of the locking block 7 and the dead weight of the locking block 7, the force for enabling the convex surfaces of the two cams 6 to continuously draw close to the middle of the arc groove 7-1 is applied, so that the initial horizontal state cannot be automatically recovered, and the locking state is stable.
When the gate 8 needs to be unlocked, the gate 8 is lifted up by the hoist, the gate 8 is separated from the locking limiting device, the rocker arms are rotated to the initial position in opposite directions during locking, the two cams 6 rotate synchronously, the convex surfaces of the cams 6 rotate to the horizontal position from the vertical position, the locking block 7 descends stably by means of self weight, the locking block exits from the rotating space of the locking body 2, the locking body 2 can rotate freely and does not bear load any more, and the unlocking operation of the gate 8 is realized (see fig. 10).
