Description

Technical Field

[0001] This utility model belongs to the field of aqueduct technology and relates to hoisting structures, particularly an aqueduct hoisting structure. Background Technology

[0002] Aqueduct hoisting structures are the machinery and tools used for the installation, maintenance, or dismantling of aqueducts. They help engineers and workers perform hoisting operations safely and efficiently, ensuring stability and safety. The main equipment includes cranes, hoisting machines, slings and chains, support frames, hydraulic equipment, hoisting platforms, and safety equipment. These devices are used for the component installation, periodic inspection and maintenance of new aqueducts, and the dismantling of existing aqueducts. When selecting and using this equipment, safety standards and operating procedures must be followed to ensure personal safety and the proper functioning of equipment during construction.

[0003] In most existing aqueduct hoisting structures, the connection between the aqueduct and the sling is directly made. This can lead to the slings losing strength due to friction and wear during use, increasing the risk of breakage. Therefore, this problem needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an aqueduct hoisting structure. The technical problem this utility model aims to solve is that the direct connection between the slings and the aqueduct can lead to a decrease in the strength of the slings due to friction and wear during use, increasing the risk of breakage.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A trough hoisting structure includes a base. Two first sliding grooves are formed on the top of the base. Two support rods are symmetrically fixedly connected inside the first sliding grooves. Two first clamping plates are symmetrically slidably fitted on the surfaces of the two support rods. Each of the two first clamping plates has a moving mechanism for moving the first clamping plates on its surface away from the support rods. Each of the two first clamping plates has a second storage groove on its surface near the support rods. A second clamping plate is slidably connected inside each of the two second storage grooves. Each of the two second storage grooves has an opening on one side, and an adjusting mechanism for adjusting the second clamping plates is provided inside each of the two openings. Two first storage grooves are formed on the surface of the first sliding grooves near the two first clamping plates. First tension springs are fitted on the surfaces of the two support rods near the two first storage grooves. One end of each of the two first tension springs is fixedly connected to one side of a first clamping plate, and the other end of each of the two first tension springs is fixedly connected to one side inside a first storage groove.

[0007] The working principle of this utility model is as follows: When in use, the base is first placed at the bottom of the aqueduct, and two first clamping plates are symmetrically installed on the top of the base. Both first clamping plates cooperate with the pressing plate on one side of the push plate. Because the pressing plate is set at an angle, when the sling moves the push plate upward, the pressing plate will press the push plate, so that they come closer to each other, thereby achieving the purpose of clamping and fixing the aqueduct.

[0008] The moving mechanism includes a second slide groove, which is opened on one side of the base. A push plate is slidably connected inside the second slide groove. First limiting rods are fixedly connected to both sides of the push plate. The two first limiting rods are slidably connected to the top of the base. A second tension spring is sleeved on the surface of the two first limiting rods. The top ends of the two second tension springs are fixedly connected to one side of the push plate. The bottom ends of the two second tension springs are fixedly connected to the top of the base. A connector is fixedly connected to the top of the push plate near the two first limiting rods. A pressing plate is fixedly connected to the surface of the push plate near the first clamping plate, and the pressing plate and the first clamping plate are configured to cooperate with each other.

[0009] The above structure allows the first clamping plate to move, thereby achieving the purpose of clamping and fixing the aqueduct.

[0010] The adjustment mechanism includes a third storage slot, which is located on one side of the slot opening. A rotating shaft is rotatably connected inside the third storage slot. An adjustment plate is fixedly sleeved on the surface of the rotating shaft near the slot opening, and the adjustment plate and the second clamping plate are configured to cooperate with each other. A worm gear is fixedly sleeved on one end of the rotating shaft, and a worm is fitted on the surface of the worm gear. The worm is rotatably connected inside the first clamping plate. A reset mechanism for resetting the second clamping plate is provided on the surface of the second clamping plate near the third storage slot.

[0011] The above structure allows for adjustment of the second clamping plate, thereby ensuring greater adaptability of the device.

[0012] The reset mechanism includes four second limiting rods, all of which are slidably connected to one side of the third storage slot. The four second limiting rods are evenly arranged in a square shape. All four second limiting rods are fixedly connected to one side of the second clamping plate. The other end of each of the four second limiting rods is fixedly connected to a limiting plate. A spring is sleeved on the surface of each of the four second limiting rods near the limiting plate. One end of each of the four springs is fixedly connected to one side of the limiting plate, and the other end of each spring is fixedly connected to one side inside the third storage slot.

[0013] The above structure allows the second clamping plate to be reset, thereby achieving the purpose of adjustment.

[0014] Compared with the prior art, the aqueduct hoisting structure of this utility model has the following advantages:

[0015] 1. This utility model adopts a technical solution of hoisting the aqueduct through a base and clamping plates, which can reduce the phenomenon of sling breakage. This effectively solves the problem that the sling may lose strength due to friction and wear during use when directly connected to the aqueduct, increasing the risk of breakage. In use, the base is first placed at the bottom of the aqueduct. Push plates are installed at both ends of the base, and connectors are installed on the top of the two push plates. The base and the sling can be connected through the connectors to achieve the purpose of raising and lowering the base. After the position is determined, the two push plates can be moved upward by the crane. Two first clamping plates are symmetrically installed on the top of the base, and the two first clamping plates cooperate with the pressing plate on one side of the push plate. Because the pressing plate is inclined, when the sling moves the push plate upward, the pressing plate will press the push plate, so that they come together and achieve the purpose of clamping and fixing the aqueduct.

Each of the two support rods 102 has a first tension spring 105 on the surface near the two first storage slots 104. One end of each of the two first tension springs 105 is fixedly connected to one side of the first clamping plate 2, and the other end of each of the two first tension springs 105 is fixedly connected to one side inside the first storage slot 104.

[0024] Preferably, the moving mechanism includes a second slide groove 103, which is opened on one side of the base 1. A push plate 3 is slidably connected inside the second slide groove 103. A first limiting rod 301 is fixedly connected to both sides of the push plate 3. The two first limiting rods 301 are slidably connected to the top of the base 1. A second tension spring 302 is sleeved on the surface of the two first limiting rods 301. The top ends of the two second tension springs 302 are fixedly connected to one side of the push plate 3, and the bottom ends of the two second tension springs 302 are fixedly connected to the top of the base 1. A connector 303 is fixedly connected to the top of the push plate 3 on the side near the two first limiting rods 301. A pressing plate 304 is fixedly connected to the surface of the push plate 3 on the side near the first clamping plate 2, and the pressing plate 304 and the first clamping plate 2 are configured to cooperate with each other.

[0025] Preferably, the adjustment mechanism includes a third storage slot 203, which is opened on one side of the slot opening 202. A rotating shaft 405 is rotatably connected inside the third storage slot 203. An adjustment plate 404 is fixedly sleeved on the surface of the rotating shaft 405 near the slot opening 202, and the adjustment plate 404 and the second clamping plate 4 are mutually cooperated. A worm gear 406 is fixedly sleeved on one end of the rotating shaft 405. A worm 407 is fitted on the surface of the worm gear 406. The worm 407 is rotatably connected inside the first clamping plate 2. A reset mechanism for resetting the second clamping plate 4 is provided on the surface of the second clamping plate 4 near the third storage slot 203.

[0026] Furthermore, the reset mechanism includes four second limiting rods 401. The four second limiting rods 401 are all slidably connected to one side of the third storage groove 203, and the four second limiting rods 401 are evenly arranged in a square shape. The four second limiting rods 401 are all fixedly connected to one side of the second clamping plate 4. The other end of the four second limiting rods 401 is fixedly connected to the limiting plate 402.

[0027] The working principle of this utility model is as follows: In use, the base 1 is first placed at the bottom of the aqueduct. Push plates 3 are installed at both ends of the base 1, and connectors 303 are installed on the top of each push plate 3. The base 1 can be connected to the slings via the connectors 303, thus achieving the purpose of raising and lowering the base 1. Once the position is determined, the crane can move the two push plates 3 upwards. Two first clamping plates 2 are symmetrically installed on the top of the base 1, and both first clamping plates 2 cooperate with the pressing plates 304 on one side of the push plates 3. Because the pressing plates 304 are inclined, when the slings move the push plates 3 upwards, the pressing plates 304 will press against the push plates 3, causing them to move closer together, thereby clamping and fixing the aqueduct. The purpose is to install a second clamping plate 4 on one side of each of the two first clamping plates 2, and the second clamping plate 4 slides on one side of the first clamping plate 2. When the aqueduct is too small and the first clamping plate 2 cannot clamp and fix it, the worm 407 inside the first clamping plate 2 can be rotated. A worm wheel 406 is fitted on the surface of the worm 407, and the worm wheel 406 is connected to the rotating shaft 405 on one side of the adjusting plate 404. When the worm wheel 406 rotates, the angle of the adjusting plate 404 can be adjusted. The adjusting plate 404 cooperates with the second clamping plate 4. When the angle of the adjusting plate 404 is adjusted, the second clamping plate 4 can be squeezed and moved forward, thereby ensuring that some small-sized aqueducts can be fixed.

[0028] In summary, in this utility model, during use, the base is first placed at the bottom of the aqueduct. Push plates are installed at both ends of the base, and connectors are installed on the top of both push plates. The base can be connected to the slings through the connectors to achieve the purpose of raising and lowering the base. Once the position is determined, the two push plates can be moved upward by the crane. Two first clamping plates are symmetrically installed on the top of the base, and both first clamping plates cooperate with the pressing plate on one side of the push plate. Because the pressing plate is inclined, when the slings move the push plate upward, the pressing plate will press the push plate, causing them to come closer together, thereby achieving the purpose of clamping and fixing the aqueduct.
