Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting hoisting, and in particular to a hoisting mechanism for installing water conservancy and hydropower pipe fittings. Background Art

[0002] The hoisting of water conservancy and hydropower pipe fittings refers to the process of lifting, moving and installing pipe fittings through cranes and other hoisting equipment in water conservancy and hydropower projects. This process is an important link in the construction of water conservancy and hydropower projects and is of great significance for ensuring construction progress, quality and safety.

[0003] In the process of hoisting existing water conservancy and hydropower pipe fittings, they are usually hoisted by clamping and pressing against the wall positions at both ends of the pipe fittings with clamping blocks or by binding them to the surfaces of both ends of the pipe fittings with binding straps. When the clamping method is used to hoist the pipe fittings, due to the heavy weight of the pipe fittings, the pipe ports are subjected to greater force during the clamping process, which can easily cause deformation of the ports and affect the sealing of the pipes. When the bundling method is used, when the pipe fittings shake in the air, the pipe fittings and the binding straps are prone to slippage, which poses a certain safety risk. At the same time, when these two methods are used to hoist right-angled bends, the pipe fittings are prone to tilting during the hoisting process. When adjusting, the pipe fittings are prone to shaking or tilting to a large extent, which is not conducive to installation and is difficult to operate. At the same time, when the pipe fittings collide during the installation process, it is not only easy for the operator to be scratched by the pipe fitting port, but also easy to cause damage to the pipe fitting port. Therefore, the present application provides a hoisting mechanism for the installation of water conservancy and hydropower pipe fittings to meet the needs. Summary of the invention

[0041] like Figures 1 to 12As shown, an embodiment of the present invention provides a hoisting mechanism for installing water conservancy and hydropower pipe fittings, including a hoisting plate 1, the top of the hoisting plate 1 is connected to the hoist through a steel cable 2, first motors 11 are arranged on both sides of the hoisting plate 1, a pair of sliders 12 are symmetrically arranged at the bottom of the hoisting plate 1, the sliders 12 are slidably connected to the hoisting plate 1 through the first motor 11, the bottoms of the two sliders 12 are respectively fixedly connected to a first connecting rod 31 and a second connecting rod 41, the bottom of the first connecting rod 31 is fixedly connected to a first hoisting frame 3, one side of the first hoisting frame 3 is provided with a first protective portion 5, and the first protective portion 5 is used to protect one end of the water conservancy and hydropower pipe fittings. An adjusting component 6 is arranged between the first protecting portion 5 and the first hoisting frame 3. The adjusting component 6 is used to adjust the center of gravity position of the water conservancy and hydropower pipe fittings during the hoisting process of the water conservancy and hydropower pipe fittings. The bottom of the second connecting rod 41 is rotatably connected with the second hoisting frame 4. The first hoisting frame 3 and the second hoisting frame 4 are used to clamp the water conservancy and hydropower pipe fittings. A second protecting portion 7 is arranged on one side of the second hoisting frame 4. The second protecting portion 7 is used to adjust the inclination angle of the second hoisting frame 4. When the staff hoists the water conservancy and hydropower pipe fittings with right-angle bends, when the operator moves the corresponding When one end of a pipe of the same size is inserted from one side of the first hanging frame 3, the outer surface of one end of the pipe will be clamped by the first guide roller 32 and the second guide roller 64 made of rubber and elastic, and the inclination angle of the second hanging frame 4 is adjusted by the second protection part 7, so that the second hanging frame 4 can be clamped at the right-angle bend of the water conservancy and hydropower pipe. Then the crane starts to work and gradually reels the steel cable 2. During the reeling process of the steel cable 2, the hanging plate 1 gradually rises. During the rising process, the operator can adjust the position of the pipe by controlling the first motors 11 on both sides so that the pipe can be kept Stable, the adjustment component 6 can also fine-tune the position of the pipe fittings in the air to prevent the pipe fittings from having a large swing amplitude in the air. At the same time, the adjustment component 6 can also rotate the first protection part 5 to one side of the first hanging frame 3, so that the first protection part 5 can protect one end of the water conservancy and hydropower pipe fittings located on the first hanging frame 3, and prevent dust in the air and rainwater and other debris from entering the pipeline. When installing the water conservancy and hydropower pipe fittings, the first protection part 5 will leave one end of the water conservancy and hydropower pipe fittings, so that one end of the water conservancy and hydropower pipe fittings can be connected and installed with the pipeline on the line.

[0042] As an implementation method in this embodiment, Figures 2 to 9As shown, the first protection part 5 includes a first protection frame 51, a first airbag 53 is arranged in the first protection frame 51, first air pumps 52 are fixedly connected to both sides of the first protection frame 51, the first air pump 52 and the first airbag 53 are connected by a hose, a first transmission shaft 511 is fixedly connected to one side of the top of the first protection frame 51, a first gear 512 is fixedly connected to the middle of the first transmission shaft 511, the first airbag 53 is provided with an anti-collision airbag 531, the anti-collision airbag 531 is evenly distributed on the outer surface of the first protection frame 51, sealing airbags 532 are arranged on both sides of the first airbag 53, and a group of auxiliary rods 533 are sealingly and slidably connected to one side of the first protection frame 51, and the auxiliary rods 533 pass through one side of the first protection frame 51 and the inner side of the first hanging frame 3. The bottom is rotatably connected to the first guide roller 32, a group of positioning holes 33 are opened on one side of the first hanging frame 3, the number and position of the positioning holes 33 correspond to the number and position of the auxiliary rods 533, the first protection frame 51 is rotatably connected to one side of the first hanging frame 3 through the first transmission shaft 511, the adjustment component 6 includes a second motor 61, the second motor 61 is meshed and connected with the auxiliary frame 62 through gears, a second transmission shaft 63 is arranged below the auxiliary frame 62, the second transmission shaft 63 is connected to the second guide roller 64 through a belt, a first oil storage rod 65 is arranged on one side of the auxiliary frame 62, the first oil storage rod 65 is connected to the second oil storage rod 66 through a hose, the top of the auxiliary frame 62 is rotatably connected to the second gear 621, and one side of the auxiliary frame 62 is rotatably connected to the third The gear 622, the second gear 621 and the third gear 622 are staggered, the middle part of the second transmission shaft 63 is fixedly connected with the fourth gear 631, the fourth gear 631 is connected to the gear of the second motor 61 through the third gear 622, the first transmission wheel 632 fixedly connected at both ends of the second transmission shaft 63 is connected with the second transmission wheel 641 fixedly connected at both ends of the second guide roller 64 through a belt, one end of the first piston rod 651 in the first oil storage rod 65 is fixedly connected to one side of the auxiliary frame 62, the second oil storage rod 66 is internally slidably connected with the second piston rod 661, the first oil storage rod 65 and the second oil storage rod 66 are both provided with a return spring, the gear on the second motor 61 is connected to the first gear 512 through the second gear 621, and the second motor 6 1 is fixedly connected to the top of the first hanging frame 3, the auxiliary frame 62 is slidably connected to the upper part of the first hanging frame 3, the second guide roller 64 is rotatably connected to the top of the inner side of the first hanging frame 3, and the second oil storage rod 66 is fixedly connected to the positioning hole 33 located above the first hanging frame 3. When the operator places one end of the pipe fitting in the first hanging frame 3, the one end of the pipe fitting will be clamped between the first guide roller 32 and the second guide roller 64, and then the second motor 61 starts to rotate. When the second motor 61 starts to rotate, the second gear 621 meshed with the gear on the second motor 61 starts to rotate. Since the second gear 621 is meshed with the first gear 512 at this time, the first transmission shaft 511 will start to rotate under the action of the second gear 621.As a result, one side of the first protection frame 51 gradually approaches one side of the first hanging frame 3. When the first protection frame 51 is fitted with the first hanging frame 3, the second motor 61 stops rotating, and the first air pump 52 starts to inflate the first airbag 53, so that the first airbag 53 is completely inflated. During the inflating process of the first airbag 53, the gas in the first airbag 53 pushes the auxiliary rod 533, so that the auxiliary rod 533 extends out and is inserted into the positioning hole 33. When the auxiliary rod 533 located above is inserted into the positioning hole 33 above the first hanging frame 3, the auxiliary rod 533 pushes the second piston rod 661, so that part of the oil in the second oil storage rod 66 enters the first oil storage rod 65 through the hose and pushes the first piston rod 651. When the first piston rod 6 When the auxiliary frame 62 is extended, the auxiliary frame 62 is pushed to move the auxiliary frame 62 in the first hanging frame 3. When the auxiliary frame 62 moves, the second gear 621 is separated from the gear of the second motor 61 and the first gear 512, and the third gear 622 begins to mesh with the gear of the second motor 61 and the fourth gear 631. When the auxiliary frame 62 stops moving, the operator can adjust the position of the pipe according to the state of the pipe. When the pipe is tilted, the operator controls the second motor 61 to rotate. When the second motor 61 rotates, the gear on the second motor 61 drives the fourth gear 631 to rotate through the third gear 622. When the fourth gear 631 rotates, the first transmission wheels 632 on both sides of the second transmission shaft 63 are driven by the belt The second transmission wheel 641 rotates, thereby rotating the second guide roller 64, so that the pipe clamped at one end moves to the left through the friction of the second guide roller 64 made of rubber on the pipe, and because the other end of the pipe is clamped in the second hanging frame 4, the second hanging frame 4 moves to the left on the inner side of the hanging plate 1 through the slider 12 installed above, and the positions of the first connecting rod 31 and the second connecting rod 41 are adjusted synchronously, so that the first hanging frame 3 and the second hanging frame 4 are in the most stable position for clamping the pipe to maintain balance, so as to achieve the effect of fine-tuning the clamping position and improving stability. When the operator needs to install the pipe, the first air pump 52 will extract the air in the first air bag 53 to restore the first air bag 53 to its original state. In this process, the air is pushed up by the air. The auxiliary rod 533 will move back and leave the positioning hole 33. In the process of the upper auxiliary rod 533 leaving the upper positioning hole 33, the second piston rod 661 and the first piston rod 651 will gradually move back. Under the action of the first piston rod 651, the auxiliary frame 62 will also move in the opposite direction synchronously, so that the third gear 622 is separated from the gear of the second motor 61 and the fourth gear 631, and the second gear 621 is connected with the gear of the second motor 61 and the first gear 512. Then the operator controls the second motor 61 to rotate, and the gear of the second motor 61 drives the first gear 512 to rotate through the second gear 621, so that the first protection frame 51 gradually moves away from one side of the first hanging frame 3. In this process, one end of the pipe is gradually exposed.When one end of the pipe is completely exposed, the operator can then connect and install the pipe on the line.

[0043] In this embodiment, if Figures 2 to 9 As shown, after the first airbag 53 is inflated, the anti-collision airbag 531 will be in a bulging state. During the process of pipe hoisting, the installer can be prevented from being scratched by the edge of the pipe when in contact with the pipe. The sealing airbag 532 will swell up and enter one end of the pipe when inflated. When the pipe collides, it can increase the buffer to avoid damage to the port of the pipe and affect the sealing of the pipe during installation. At the same time, the second guide roller 64 drives the pipe to move and adjust in a small range in the air. At this time, the second lifting frame 4 moves to the left on the inner side of the lifting plate 1 through the slider 12 installed above, and synchronously adjusts the position of the first connecting rod 31 and the second connecting rod 41 to achieve fine-tuning of the clamping position, so that the center of gravity of the pipe can be adjusted during hoisting, so that the pipe can maintain a stable state, avoiding a large degree of shaking when adjusting the installation angle of the pipe, and reducing safety hazards in the key lifting process.

[0044] As an implementation method in this embodiment, Figures 10 to 12As shown, the top of the second hanging frame 4 is fixedly connected with a fifth gear 42, and the second hanging frame 4 is rotatably connected to the bottom of the second connecting rod 41 through the fifth gear 42. The top and bottom of the inner side of the second hanging frame 4 are both provided with auxiliary rollers 411, and the auxiliary rollers 411 are rotatably connected to the auxiliary plate 412. The auxiliary plate 412 is limited and slidably connected to the second hanging frame 4 through the first spring 413. The second protection part 7 includes an electric push rod 71, and the bottom of the electric push rod 71 is fixedly connected with a toothed plate 75, and the bottom of the toothed plate 75 is fixedly connected with a second protection frame 72. The two sides of the second protection frame 72 are fixedly connected with a second air pump 73, and a second air bag 74 is provided in the second protection frame 72. The second air bag 74 is connected to the second air pump 73 through a hose. The electric push rod 71 is fixedly connected to the second connecting rod 41, and the toothed plate 75 is slidably connected to the second connecting rod 41. The toothed plate 75 is meshed with the fifth gear 42, and the second protection frame 72 is located at the second hanging frame 4. On one side, when the pipe fitting to be hoisted has a right-angle bend, the operator needs to control the electric push rod 71 to extend. When the electric push rod 71 extends, it will push the tooth plate 75 below. When the tooth plate 75 is pushed, the fifth gear 42 meshing with the tooth plate 75 will rotate. When the fifth gear 42 rotates, the angle of the second hanging frame 4 will change. When the inclination angle of the second hanging frame 4 is appropriate, the electric push rod 71 stops extending. At this time, the bent pipe of the pipe fitting needs to be placed in the second hanging frame 4 so that the bent pipe can be clamped by two sets of auxiliary rollers 411 made of rubber and with elasticity. When the pipe fitting to be hoisted is a straight pipe, the two ends of the pipe fitting will be clamped and fixed on the first hanging frame 3 and the second hanging frame 4 respectively. At this time, the second protective frame 72 is located on one side of the pipe fitting. When the second air pump 73 discharges air into the second air bag 74, the second air bag 74 will swell and protect one end of the pipe fitting located on the second hanging frame 4.

[0045] In this embodiment, if Figures 10 to 12 As shown, during use, the second lifting frame 4 can not only clamp the position of the pipe bend to keep the pipe stable during the lifting process, but also cooperate with the second protective part 7 to clamp the straight pipe and further protect the pipe to prevent rainwater and other debris from entering the interior from the port of the pipe.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When the staff is hoisting the water conservancy and hydropower pipe fittings with right-angle bends, the operator first needs to place and clamp one end of the water conservancy and hydropower pipe fittings on the first hoisting frame 3, and adjust the inclination angle of the second hoisting frame 4 through the second protection part 7, so that the second hoisting frame 4 can be clamped at the right-angle bend of the water conservancy and hydropower pipe fittings, and then the crane starts to work and gradually reels the steel cable 2. During the process of reeling the steel cable 2, the hoisting plate 1 gradually rises. During the rising process, the operator can adjust the position of the pipe fitting by controlling the first motors 11 on both sides so that the pipe fittings can remain stable and adjust the position of the pipe fittings. Component 6 can also fine-tune the position of the pipe fittings when they are in the air to prevent the pipe fittings from having a large swing amplitude in the air. At the same time, the adjustment component 6 can also rotate the first protection part 5 to one side of the first hanging frame 3, so that the first protection part 5 can protect one end of the water conservancy and hydropower pipe fittings located on the first hanging frame 3, and prevent dust in the air and rainwater and other debris from entering the pipeline. When installing the water conservancy and hydropower pipe fittings, the first protection part 5 will leave one end of the water conservancy and hydropower pipe fittings, so that one end of the water conservancy and hydropower pipe fittings can be connected and installed with the pipeline on the line.

[0048] When the operator inserts one end of a pipe of the same size from one side of the first hanging frame 3, the outer surface of one end of the pipe will be clamped by the first guide roller 32 and the second guide roller 64 made of rubber and elastic, and then the second motor 61 starts to rotate. When the second motor 61 starts to rotate, the second gear 621 meshed with the gear on the second motor 61 starts to rotate. Since the second gear 621 is meshed with the first gear 512 at this time, the first transmission shaft 511 starts to rotate under the action of the second gear 621, so that one side of the first protection frame 51 gradually approaches one side of the first hanging frame 3. When the first protection frame 51 is in contact with the first hanging frame 3, the second motor 61 stops rotating, and the first air pump 52 starts to inflate the first airbag 53, so that the first airbag 53 When the first airbag 53 is fully inflated, the gas in the first airbag 53 will push the auxiliary rod 533, so that the auxiliary rod 533 extends out and is inserted into the positioning hole 33. When the auxiliary rod 533 located above is inserted into the positioning hole 33 above the first hanging frame 3, the auxiliary rod 533 will push the second piston rod 661, so that part of the oil in the second oil storage rod 66 enters the first oil storage rod 65 through the hose and pushes the first piston rod 651. When the first piston rod 651 is extended, it will push the auxiliary frame 62, so that the auxiliary frame 62 moves in the first hanging frame 3. When the auxiliary frame 62 moves, the second gear 621 is separated from the gear of the second motor 61 and the first gear 512, and the third gear 622 begins to mesh with the gear of the second motor 61 and the fourth gear 631.

[0049] When the auxiliary frame 62 stops moving, the operator can adjust the position of the pipe according to the state of the pipe. When the pipe is tilted, the operator controls the second motor 61 to rotate. When the second motor 61 rotates, the gear on the second motor 61 drives the fourth gear 631 to rotate through the third gear 622. When the fourth gear 631 rotates, the first transmission wheels 632 on both sides of the second transmission shaft 63 drive the second transmission wheel 641 to rotate through the belt, thereby rotating the second guide roller 64, so that the pipe clamped at one end is moved to the left through the friction force of the second guide roller 64 made of rubber on the pipe. Because the other end of the pipe is clamped in the second hanging frame 4, the second hanging frame 4 moves to the left on the inner side of the hanging plate 1 through the slider 12 installed above, so that the first hanging frame 3 and the second hanging frame 4 are in the most stable position to clamp the pipe to maintain balance, so as to achieve fine-tuning of the clamping position. To improve the stability, when the operator needs to install the pipe fittings, the first air pump 52 will extract the air in the first air bag 53 to restore the first air bag 53 to its original state. During this process, the auxiliary rod 533 pushed out by the air will move back and leave the positioning hole 33. In the process of the upper auxiliary rod 533 leaving the upper positioning hole 33, the second piston rod 661 and the first piston rod 651 will gradually move back. Under the action of the first piston rod 651, the auxiliary frame 62 will also move in the opposite direction synchronously, so that the third gear 622 is separated from the gear of the second motor 61 and the fourth gear 631, and the second gear 621 is connected to the gear of the second motor 61 and the first gear 512. Then the operator controls the second motor 61 to rotate, and the gear of the second motor 61 drives the first gear 512 to rotate through the second gear 621, so that the first protection frame 51 gradually moves away from one side of the first hanging frame 3.

[0050] During this process, one end of the pipe fitting is gradually exposed. When one end of the pipe fitting is completely exposed, the operator can connect and install the pipe fitting on the line. After the first airbag 53 is inflated, the anti-collision airbag 531 will be in a bulging state. During the process of pipe fitting hoisting, it can prevent the installer from being scratched by the edge of the pipe fitting when contacting the pipe fitting. The sealing airbag 532 will swell and enter one end of the pipe fitting when inflated. When the pipe fitting collides, it can increase the buffer to prevent the port of the pipe fitting from being damaged and affecting the sealing of the pipe fitting during installation. At the same time, the second guide roller 64 drives the pipe fitting to move and adjust in a small range in the air, so that the position of the center of gravity of the pipe fitting can be adjusted during hoisting, so that the pipe fitting can maintain a stable state, avoiding a large degree of shaking when adjusting the installation angle of the pipe fitting, and reducing the safety hazards in the key hoisting process. When the pipe fitting to be hoisted has a right-angle bend, the operator needs to control the electric push rod 71 to extend. When the electric push rod 71 extends, it will push the tooth plate 75 below. When the tooth plate 75 When pushed, the fifth gear 42 meshing with the tooth plate 75 will rotate. When the fifth gear 42 rotates, the angle of the second hanging frame 4 will change. When the second hanging frame 4 is tilted at a suitable angle, the electric push rod 71 stops extending. At this time, the bent pipe of the pipe fitting needs to be placed in the second hanging frame 4 so that the bent pipe can be clamped by the two sets of auxiliary rollers 411 made of rubber and having elasticity. When the pipe fitting to be hoisted is a straight pipe, the two ends of the pipe fitting will be clamped and fixed on the first hanging frame 3 and the second hanging frame 4 respectively. At this time, the second protection frame 72 is located on one side of the pipe fitting. When the second air pump 73 discharges air into the second air bag 74, the second air bag 74 will swell and protect one end of the pipe fitting located on the second lifting frame 4. During use, the second lifting frame 4 can not only clamp the position of the pipe bend to keep the pipe fitting in a stable state during the lifting process, but also cooperate with the second protection part 7 to clamp the straight pipe fitting and further protect the pipe fitting to prevent rainwater and other debris in the air from entering the interior from the port of the pipe fitting.
