Detailed Description

As shown in fig. 1 and 2, the gate lifting mechanical unhooking and mechanical hooking device of the present invention comprises: weight and lifting hook 8, weight and lifting hook 8 link together through round pin axle 6, and the weight includes: tup 1, connecting plate 2 and rod iron 4, tup 1 are cylindrical, and the one end of two connecting plates 2 is fixed at its lower extreme along cylindrical tup 1's length direction, and the other end is articulated through the one end of round pin axle 6 with lifting hook 8, and one side of two connecting plates 2 is opened jaggedly 3. The other end of the lifting hook 8 is a hook 7, a steel bar 4 is arranged between the two connecting plates 2 close to one end of the lifting hook 8, two sides of one end of the lifting hook 8 are respectively provided with a bulge 5, when the heavy hammer rotates around the pin shaft 6, the steel bar 4 is limited between the two bulges 5, and the steel bar 4 on the heavy hammer stirs the bulge 5 on the lifting hook to drive the lifting hook 8 to rotate.

The utility model discloses a gate lifts by crane mechanical unhook and mechanical couple device mainly includes following seven steps:

the method comprises the following steps: the hanging shaft 16 is connected with the lower beam body 17, and the hung object-gate is connected with the lower beam body 17;

step two: connecting an upper hanging beam 15 with an upper hanging ring 13 and a chain 14, and connecting the upper hanging ring 13 with a crane hook;

step three: the heavy hammer and the lifting hook 8 of the utility model are arranged in the center of the upper hanging beam 15 through the pin shaft 6;

step four: as shown in fig. 3 to 7, the automatic hook weight position mark 11 is attached to the upper hanging beam 15, i.e. the automatic hook weight position mark 11 is attached to the left side of the pin 6; attaching the position mark 12 of the automatic unhooking weight on the upper hanging beam 15, namely attaching the position mark 12 of the automatic unhooking weight on the right side of the pin shaft 6;

step five: one side of a supporting leg 18 of the upper hanging beam 15 is provided with a guide wheel 19, the other side is provided with a guide limiting device 20, and the upper hanging beam 15 can only move linearly up and down under the action of the guide wheel 19, the guide limiting device 20 and a guide rail (not shown in the figure);

step six: the crown block hook is connected with an upper hanging beam 15, and the hanging hook 8 is in a vertical state due to self weight and the limitation of the lower baffle 10. Before the gate installed on the lower hanging beam 17 is lifted, an operator manually pulls the hammer head 1 to one side of the position mark 11 of the automatic hook hammer, the upper hanging beam 15 linearly descends to the water along the gate guide rail through the guide wheels 19 and the guide limiting devices 20 on the two sides of the supporting leg 18, when the lower hook 7 of the hook 8 touches the hanging shaft 16 of the lower hanging beam 17, the hanging shaft 16 pushes the hook 8 away (as shown in fig. 4), the upper hanging beam 15 continuously descends, and the hook 8 automatically hangs into the hanging shaft 16 (as shown in fig. 5) due to the self weight, so that the automatic hook is completed. And the upper hanging beam 15, the lower hanging beam 17 and the gate arranged on the lower hanging beam 17 are lifted upwards through the top hook, so that the gate lifting is completed.

Step seven: before placing the gate, the operator manually pulls the hammer 1 to one side of the position mark 12 of the self-unhooking hammer, through the guide wheels 19 and the guide limiting devices 20 on two sides of the supporting leg 18 of the upper hanging beam 15, the upper hanging beam 15 linearly descends into water along the gate guide rail, after the gate arranged on the lower hanging beam 17 enters an underwater specified position, the lower hanging beam 17 and the gate are not moved, the upper hanging beam 15 continues to descend, the lifting hook 8 of the upper hanging beam 15 enters an idle state, meanwhile, the hammer 1 falls to the position of the upper baffle plate 9 due to self weight, and meanwhile, the steel rod 4 on the hammer stirs the lifting hook 8 to enter an unhooking state, so that automatic unhooking is completed. The overhead traveling crane hooks the upper hanging beam 15 and places the lower hanging beam 17 and the gate mounted thereon in the water, thereby completing gate placement.
