Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated aqueduct hoisting structure. Background Art

[0002] An aqueduct is an overhead channel that conveys water across rivers, valleys, depressions, and roads. It is commonly used for irrigation, flood control, and sediment removal, and large aqueducts can also be navigable. Constructed primarily of stone masonry, concrete, and reinforced concrete, aqueducts, as water-conveying structures, are widely used in civil engineering. Prefabricated aqueducts, owing to their high efficiency and ease of construction, are widely used in aqueduct projects.

[0003] Announcement No. CN217296921U discloses a prefabricated aqueduct hoisting structure for hoisting prefabricated aqueducts, including a hanger base plate, a hanger upright plate and a hoisting top plate, wherein the limit piers are placed on the hanger base plate, at least two hanger upright plates are placed on both end sides of the hoisting base plate, the hanger top plate is placed on the top of two mirror-opposite hanger upright plates, the segment clamping bolts pass through the hanger top plate and are arranged in the direction of the limit piers, and the hoisting top plate is provided with external hoisting equipment, which can not only reduce the difficulty of aqueduct hoisting construction, but also improve the quality of aqueduct hoisting construction.

[0004] In the existing aqueduct hoisting construction, rope hoisting is usually adopted, and the rope is directly connected to the aqueduct, and the hoisting stability is poor. The aqueduct hoisted by the rope is swaying in the air, which is easy to collide with the aqueduct and cause damage to the aqueduct. In addition, when the rope is used to hoist the prefabricated aqueduct, the rope hoisting the aqueduct in the air causes the rope to cause the aqueduct to shake, resulting in friction at the connection between the rope and the aqueduct. Using a rope to hoist the aqueduct multiple times is easy to cause the rope to break, which is easy to cause production accidents, which is dangerous. For this reason, we propose a prefabricated aqueduct hoisting structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated aqueduct hoisting structure to solve the problem proposed in the above-mentioned background technology that when using ropes to hoist the prefabricated aqueduct, the ropes will cause the aqueduct to shake because the ropes are hoisted in the air, resulting in friction at the connection between the ropes and the aqueduct. Using one rope to hoist the aqueduct multiple times can easily cause the rope to break, thereby easily causing production accidents and posing certain risks.

[0030] The rotating plates 5 are provided with four groups, and the four groups of rotating plates 5 are rotatably installed in the four groups of rotating seats 4;

[0031] The lifting rings 6 are provided in four groups, and the four groups of lifting rings 6 are fixedly mounted on the upper sides of the opposite ends of the four groups of rotating plates 5;

[0032] The adjusting component is movably mounted on the bottom plate 1 and the positioning pier 2. The adjusting component is used to adjust the distance between the two groups of positioning piers 2. The device places the prefabricated aqueduct in the two groups of positioning piers 2, and then connects it to the four groups of lifting rings 6 through ropes. The ropes drive the opposite ends of the four groups of rotating plates 5 to rise, and the opposite ends of the four groups of rotating plates 5 are lowered to fit the upper end of the prefabricated aqueduct, so that the prefabricated aqueduct can be fixed. Then, the adjusting component can be used to adapt and place prefabricated aqueducts of different widths.

[0033] Furthermore, the adjustment component includes a slide groove 7, which is opened in the base plate 1, and an opposing screw rod 8 is rotatably installed in the slide groove 7. Slide blocks 9 are fixedly installed on the lower sides of the two groups of positioning piers 2. The two groups of slide blocks 9 are sleeved on the left and right ends of the opposing screw rod 8. This structure drives the connected slide blocks 9 to slide in the slide groove 7 by rotating the opposing screw rod 8, so that the two groups of positioning piers 2 can be moved closer or farther away.

[0034] Furthermore, two groups of second screw rods 10 are installed in the upper ends of the two groups of positioning piers 2, and three groups of synchronous wheels 11 are rotatably installed in the lower ends of the two groups of side panels 3. The four groups of synchronous wheels 11 at the front and rear ends of the two groups of side panels 3 are fixedly connected to the upper ends of the four groups of second screw rods 10, and two groups of synchronous belts 12 are sleeved on the six groups of synchronous wheels 11. Two groups of synchronous wheels 11 are installed in the middle of the two groups of side panels 3, and rotating handles 13 are fixedly installed on them. This structure drives the three groups of synchronous wheels 11 and the synchronous belts 12 to rotate by rotating the rotating handles 13. The rotation of the synchronous wheels 11 drives the second screw rod 10 to rotate in the positioning pier 2, so that the side panels 3 can be raised on the positioning pier 2, which is convenient for fixing prefabricated aqueducts of different heights.

[0035] Furthermore, the two groups of positioning piers 2 are L-shaped, and the inner walls of the lower ends of the two groups of positioning piers 2 are arc-shaped. This structure makes the lower end of the prefabricated aqueduct fit with the inner walls of the lower ends of the two groups of positioning piers 2 according to the shape of the two groups of positioning piers 2.

[0036] Furthermore, rubber pads 14 are glued to the inner walls of the lower ends of the two groups of positioning piers 2. This structure prevents wear and damage to the prefabricated aqueduct and the inner walls of the positioning piers 2 when the prefabricated aqueduct is placed in the two groups of positioning piers 2 through the rubber pads 14 on the inner walls of the two groups of positioning piers 2.

[0037] Furthermore, the middle positions of the four groups of rotating plates 5 are rotatably connected to the four groups of rotating seats 4, and the opposite ends of the four groups of rotating plates 5 protrude from the inner wall of the positioning pier 2. The opposite ends of the four groups of rotating plates 5 are located between the two groups of positioning piers 2. This structure is based on the installation position of the four groups of rotating plates 5, so that when the opposite ends of the four groups of rotating plates 5 are raised, the opposite ends of the four groups of rotating plates 5 are attached to the upper edge of the prefabricated aqueduct.

[0038] Working principle: When hoisting the prefabricated aqueduct, Figure 2 、 Figure 3 and Figure 4 As shown, first rotate the opposing screw rod 8, and the opposing screw rod 8 rotates to drive the two sets of sliders 9 to slide in the slide groove 7. The two sets of sliders 9 slide and drive the two sets of positioning piers 2 to move closer or farther away, and then the prefabricated aqueduct is placed in the two sets of positioning piers 2. According to the height of the prefabricated aqueduct, rotate the rotating handle 13. The rotating handle 13 rotates and drives the two sets of synchronous wheels 11 to rotate. The two sets of synchronous wheels 11 rotate and drive the two sets of synchronous belts 12 and rotate the four sets of synchronous wheels 11 in the front and rear ends of the two sets of positioning piers 2. The four sets of synchronous wheels 11 rotate and drive the four sets of second screw rods 10 to rotate. The four sets of second screw rods 10 rotate and slide out from the two sets of positioning piers 2,
