Description

Technical Field

[0001] The utility model relates to the field of gate turning, in particular to a large gate turning auxiliary tooling. Background Art

[0002] Large gates such as accident inspection gates and flat working gates weigh dozens of tons each, and each section is relatively high. There is a great safety risk in upright transportation, so they must be dismantled and turned over before anti-corrosion overhaul to facilitate gate transportation. At present, the turning operation of the Gezhouba gate is to weld the turning lugs, use the turning piers and the gate crane to drive the gate to turn over. Although it reduces the safety risk compared with turning over in mid-air, due to the large size and weight of the gate, the bottom of both sides of the gate will generate impact force at the moment of leaving the pier during the turning process, and there are still safety hazards such as loose constraints, broken wire ropes, and falling and injuring people. Therefore, in order to reduce the safety risks of hoisting and turning over, improve work efficiency, and reduce economic costs, turning tooling is used to turn over large gates.

[0005] In a preferred solution, a baffle is provided at the rear of the base, and when the flip seat rotates to the bottom and contacts the baffle, the flip seat is in a horizontal state.

[0018] like Figures 1 to 3 As shown, a large gate turning auxiliary tooling includes two sets of turning support mechanisms. The two ends of the large gate are respectively placed on the two sets of turning support mechanisms. The gate is arranged vertically. Since the lengths of different gates vary significantly, two independent turning support mechanisms are used to support the two ends of the bottom of the gate. The turning operation of gates of different lengths can be adjusted by changing the spacing between the turning support mechanisms.

[0019] The flip support mechanism includes a base 1, a receiving cavity is provided on the upper side of the base 1, and a flip seat 2 is provided in the receiving cavity. Specifically, the base 1 includes support plates 101 on both sides, the support plates 101 are connected by a connecting plate 102, two groups of support plates 101 and the connecting plate 101 form the receiving cavity, and the flip seat 2 is arranged between the two groups of support plates 101.

[0020] The flip seat 2 is rotatably mounted on the base 1 via the rotating shaft 3. A placement groove 201 is provided on the upper side of the flip seat 2. The length of the placement groove 201 is determined according to the thickness of the gate. In specific use, the base 1 and the flip seat 2 are both hollow structures, which are made by welding 20mm steel plates, so that they have a large load-bearing capacity while not being bulky, which is beneficial to reducing the weight of the entire tooling and facilitating movement. Since the placement groove 201 is provided on the flip seat 2, the gate can be limited to prevent the gate from sliding greatly during the turning process.

[0021] like Figure 3 As shown, a limit plate 4 is provided on one side of the base 1, and through holes cooperating with the positioning pin 5 are provided on the limit plate 4 and the rotating shaft 3. When the flip seat 2 is flipped to a horizontal state, the positioning pin 6 is used for positioning to keep the flip seat 2 in a horizontal state, which is conducive to lifting the gate to the placement groove 201. When the flip seat 2 is in a horizontal state, the height of the bottom of the placement groove 201 of the flip seat 2 is higher than the height of the base 1, so as to prevent the gate from touching the base 1 and affecting the flat placement of the gate.

[0022] Preferably, a baffle 7 is provided at the rear of the base 1. When the flip seat 2 rotates to the bottom and contacts the baffle 7, the flip seat 2 is in a horizontal state. At this time, the baffle 7 supports the flip seat 2. When the gate is placed vertically on the flip seat 2, it remains stable, and the baffle 7 also strengthens the lateral structural strength of the base 1.

[0023] Preferably, reinforcing ribs 103 are provided on the outer side of the support plate 101 so that the base 1 has a greater load-bearing capacity in the longitudinal direction.

[0024] Preferably, an inclined surface is provided on the upper side of the support plate 101. When the flip seat 2 flips to the front end to contact the ground, the height of the bottom of the placement groove 201 is higher than the height of the inclined surface, so that the support plate 101 will not interfere with the gate when the flip seat 2 flips.

[0025] A limit baffle 104 is provided on the side of the base 1 away from the large gate to limit the horizontal position of the large gate. The two groups of limit baffles 104 of the flipping support mechanism are respectively arranged at both ends of the large gate to prevent the gate from moving horizontally during the flipping process and reduce the risk.

[0026] The use process of this tool is as follows:

[0027] 1. Place the flip support mechanism in parallel and in alignment with the length of the lifting gate, rotate the flip seat 2 to a horizontal position, support the flip seat 2 with the baffle 6, insert the positioning pin 5 into the through holes of the rotating shaft 3 and the limit plate 4, and keep the flip seat 2 in a horizontal state;

[0028] 2. Use the wire rope of the dam top gantry crane to lift the gate through the lifting lugs, and place the bottom of the gate flat on the placement groove 201;

[0029] 3. Pull out the positioning pin 5, use the door machine to pull the top of the gate, and drive the gate to rotate slowly around the rotating shaft 3 and the turning seat 2 synchronously;

[0030] 4. After the gate is turned over, use the wire rope of the dam top gantry crane to lift the gate horizontally through the diagonal lifting ears on the gate flat plate and place it on the trailer, and pull it to the metal knot center for anti-corrosion overhaul.
