[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A hydraulic engineering pipeline hoisting auxiliary device includes two base plates 1. A support column 2 is welded to the top of the base plate 1. A threaded rod 3 is rotatably connected to the inner side of the left support column 2. A limit rod 4 is fixedly connected to the inner side of the right support column 2. A first motor 5 is installed on the top of the left support column 2. A connecting shaft is connected to the top of the threaded rod 3 through a flat key. The output end of the bottom of the first motor 5 passes through the support column 2 and is fixedly connected to the top of the connecting shaft. A hoisting mechanism 6 is threadedly connected to the surface of the threaded rod 3. An auxiliary mechanism 7 is fixedly connected to the top of the hoisting mechanism 6.

[0027] The auxiliary mechanism 7 includes two fixed blocks 71, a rotating rod 72, a protective cover 73, a wind speed sensor 74, a controller, and a stepper motor 76. The fixed blocks 71 are welded to both sides of the top of the hoisting mechanism 6, and the rotating rod 72 is rotatably connected to the inside of the fixed blocks 71.

[0028] In this embodiment: The base plate 1 provides a stable bottom bearing surface for the entire hoisting auxiliary equipment, dispersing the pressure generated during operation and enhancing the equipment's stability in different ground environments. The support column 2 provides installation support points for components such as the threaded rod 3, the limiting rod 4, and the first motor 5, constructing a vertical force-bearing frame for the equipment. This ensures that the hoisting mechanism 6 and the auxiliary mechanism 7 maintain vertical stability during lifting and operation. The threaded rod 3, in cooperation with the first motor 5, converts the rotational motion of the first motor 5 into the vertical lifting motion of the hoisting mechanism 6, achieving control over the pipe hoisting height. The limiting rod 4 is set parallel to the threaded rod 3, limiting and guiding the movement of the hoisting mechanism 6, restricting the support beam 61 to move only in the vertical direction, preventing it from shifting or rotating during lifting. The first motor 5 provides the rotational support for the threaded rod 3. The power source is provided by the fixed block 71, which provides a mounting fulcrum for the rotating rod 72, enabling the rotating rod 72 to be stably connected to the hoisting mechanism 6. The rotating rod 72 connects the fixed block 71 and the protective cover 73, transmitting the rotational power of the stepper motor 76 to the protective cover 73, allowing the protective cover 73 to rotate around the axis of the rotating rod 72. The protective cover 73 can rotate downwards through the cooperation of the stepper motor 76 and the rotating rod 72, protecting the front of the hoisting mechanism 6 and reducing the impact of wind speed on the hoisting mechanism 6. The controller receives the wind force data transmitted by the wind speed sensor 74 and compares it with the preset safety threshold. Based on the analysis results, it controls the operating state of the stepper motor 76 to achieve automated intelligent protection. The stepper motor 76 drives the rotating rod 72 and the protective cover 73 to rotate by controlling the rotation angle and speed, thus protecting the hoisting mechanism 6.

[0029] Specifically, such as Figure 2 , Figure 3As shown, the side of the rotating rod 72 away from the fixed block 71 passes through and is fixedly connected to both sides of the protective cover 73. The protective cover 73 is rotatably connected to the top of the hoisting mechanism 6. The wind speed sensor 74 is installed on the top of the protective cover 73. The controller is installed on the front side of the left support column 2. The right side of the rotating rod 72 is fixedly connected to the mounting block. The stepper motor 76 is installed on the right side of the mounting block. The output end of the stepper motor 76 on the left side passes through the mounting block and is fixedly connected to the right side of the rotating rod 72.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the hoisting mechanism 6 includes a support beam 61, a moving groove 62, a connecting shaft 63, a second motor 64, a lead screw 65, a threaded block 66, a connecting rod 67, a lower half locking ring 68, and an upper half locking ring 69. The left side of the support beam 61 is threadedly connected to the surface of the threaded rod 3.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the right side of the support beam 61 is slidably connected to the surface of the limiting rod 4, the moving groove 62 is opened at the bottom of the inner side of the support beam 61, the connecting shaft 63 is fixedly connected to the inner side of the moving groove 62, the second motor 64 is installed on the right side of the moving groove 62, and the two lead screws 65 are fixedly connected to both sides of the connecting shaft 63.

[0032] In this embodiment: By setting a support beam 61 to connect the threaded rod 3 and the limiting rod 4, the load during the hoisting process is transferred to the support column 2 and the base plate 1. The moving groove 62 provides installation space and a movement track for the threaded block 66 and the lead screw 65. The connecting shaft 63 can transmit the rotation of the right lead screw 65 to the left lead screw 65, so that the lead screws 65 on both sides can move synchronously towards or away from each other. The second motor 64 drives the right lead screw 65 to rotate, providing power for the horizontal movement of the lower half locking ring 68 and the upper half locking ring 69. The thread of the left lead screw 65 is set to clockwise, and the thread of the right lead screw 65 is set to counterclockwise. At the same time, it cooperates with the threaded block 66. The rotational motion of the second motor 64 is converted into the linear motion of the threaded block 66. Driven by the lead screw 65, the threaded block 66 moves horizontally along the moving groove 62. Through the connecting rod 67, the lower half-clamping ring 68 and the upper half-clamping ring 69 move synchronously. The connecting rod 67 transmits the horizontal motion of the threaded block 66 to the lower half-clamping ring 68, so that the lower half-clamping ring 68 can move synchronously with the movement of the threaded block 66. The lower half-clamping ring 68 and the upper half-clamping ring 69 cooperate to form a clamping structure for the pipe. The upper half-clamping ring 69 and the lower half-clamping ring 68 together constitute a complete pipe clamping device. The opening and closing of the device with the lower half-clamping ring 68 is achieved by rotation.

[0033] Specifically, such as Figure 4 , Figure 5As shown, the threaded block 66 is threadedly connected to the surface of the lead screw 65, the connecting rod 67 is welded to the bottom of the threaded block 66, the lower half of the locking ring 68 is welded to the front side of the bottom of the connecting rod 67, and the upper half of the locking ring 69 is rotatably connected to the top of the lower half of the locking ring 68.

[0034] Specifically, such as Figure 5 As shown, a snap-fit ​​groove 8 is provided on the top of the rear side of the lower snap-fit ​​ring 68, and a snap-fit ​​block 9 is welded to the bottom of the rear side of the upper snap-fit ​​ring 69. The snap-fit ​​block 9 and the snap-fit ​​groove 8 are engaged to snap together.

[0035] In this embodiment: by setting the snap-fit ​​groove 8, which cooperates with the snap-fit ​​block 9, the upper snap-fit ​​ring 69 and the lower snap-fit ​​ring 68 can be quickly connected and locked. By setting the snap-fit ​​block 9, which cooperates with the snap-fit ​​groove 8 of the lower snap-fit ​​ring 68, the upper snap-fit ​​ring 69 and the lower snap-fit ​​ring 68 can be tightly connected.

[0036] Specifically, such as Figure 5 As shown, the inner walls of both the upper half snap ring 69 and the lower half snap ring 68 are fitted with protective sleeves 10, and the surface of the protective sleeves 10 is engraved with anti-slip textures.

[0037] Specifically, such as Figure 4 As shown, a reinforcing ring 11 is welded to the connection between the top of the connecting rod 67 and the threaded block 66, and the surface of the reinforcing ring 11 is coated with an anti-corrosion coating.

[0038] In this embodiment: by setting a protective sleeve 10, the clamping ring is prevented from directly contacting the pipe surface, thus preventing scratches, wear, and other damage to the pipe surface during clamping. By setting anti-slip textures, the friction between the ring and the pipe is increased, effectively preventing the pipe from sliding during hoisting. By setting a reinforcing ring 11, the structural strength and fatigue resistance of this part are enhanced, the stress borne by the connecting rod 67 during hoisting is distributed, and the risk of breakage at the connection due to excessive force is reduced. By setting an anti-corrosion coating, the reinforcing ring 11 can adapt to the complex outdoor environment of water conservancy projects, extending the service life of the equipment.

[0039] Working Principle: First, the operator places the equipment on the work site using the base plate 1. Then, the operator starts the first motor 5 via the PLC controller 75. Its output power is transmitted to the threaded rod 3 through the connecting shaft. The rotation of the threaded rod 3 causes the lifting mechanism 6, which is threaded to it, to rise and fall vertically along the limit rod 4, controlling the pipe lifting height. Next, when it is necessary to clamp the pipe, the operator starts the second motor 64 via the PLC controller 75, which drives the lead screw 65 to rotate. Since the thread on the left lead screw 65 is clockwise and the right lead screw is counterclockwise, the two lead screws 65 synchronously drive the threaded blocks 66 to move towards or away from each other along the moving groove 62. The threaded blocks 66, through the connecting rod 67, drive the lower half of the locking ring 68 and the upper half of the locking ring 69 to move horizontally. Afterwards, the operator... After the operator places the pipe inside, the operator then rotates the upper half of the locking ring 69 to engage the locking block 9 with the locking groove 8 of the lower half of the locking ring 68, thus clamping the pipe. Then, during the hoisting process, the wind speed sensor 74 monitors the ambient wind force data in real time and transmits it to the PLC controller 75. The PLC controller 75 compares the received data with the preset safety threshold. If the wind force exceeds the threshold, the controller controls the stepper motor 76 to operate. The stepper motor 76 drives the rotating rod 72 and the protective cover 73 to rotate. The protective cover 73 rotates downward to protect the front of the hoisting mechanism 6 and reduce the impact of wind speed. Finally, after the pipe is hoisted, the operator can reset the first motor 5 and the second motor 64 by controlling the PLC controller 75.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
