[0002] The use of bridge pipes for drainage pipes is a flexible and efficient solution, especially suitable for scenes with complex terrain, ecological sensitivity or limited underground space. Its core advantages are convenient construction and simple maintenance. However, due to the need to bypass obstacles or to match the undulating terrain, multiple bends will be designed. In the prior art, the installation of bends is carried out by hoisting, and the bends are wrapped with soft slings or nylon slings, and generally the hanging points are set at both ends of the bends or symmetrical positions. When installing the bends, the plane where the outer arc and the inner arc are located is generally perpendicular to the horizontal plane. However, when the bends are wrapped and fixed with soft slings or nylon slings, there will be slippage between the pipe and the soft slings and nylon slings. Therefore, when the inner contour of the bend needs to be facing downward, due to the influence of the center of gravity of the bend, the outer contour of the bend will deflect downward, so it is impossible to maintain a stable angle or direction during installation, which increases the difficulty of installation and docking between the bend and the straight pipe.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-9 The present invention provides a technical solution for a drainage pipe hoisting and installation device: A drainage pipe hoisting and installation device is used to hoist an angled curved pipe 1, including a clamping part, two clamping parts are provided, and the two clamping parts are symmetrically arranged about the curved pipe 1. The clamping part includes a positioning arc plate 3 and a clamping arc plate 4 made of steel plate. There is one positioning arc plate 3, and there are two clamping arc plates 4. The two clamping arc plates 4 are symmetrically arranged about the positioning arc plate 3. The clamping arc plate 4 is hinged to the positioning arc plate 3, and its hinge axis is parallel to the axis of the positioning arc plate 3. The hinge axis is located on the outer side of the positioning arc plate 3. A reset torsion spring 5 is sleeved on the hinge axis. Under the action of the reset torsion spring 5, a complete arc plate is not formed between the positioning arc plate 3 and the clamping arc plate 4.

[0021] When the clamping part clamps the bent pipe 1, the two clamping arc plates 4 and the positioning arc plate 3 form an excellent arc, at which time the reset torque of the reset torsion spring 5 increases, and at least one clamping assembly is provided on the positioning arc plate 3 along its radial direction. In this embodiment, two clamping assemblies are provided on each positioning arc plate 3, and the two clamping assemblies are symmetrical about the positioning arc plate 3. At least one clamping assembly is provided on the clamping arc plate 4 along its radial direction. In this embodiment, one clamping assembly is provided on the clamping arc plate 4, and the clamping assembly includes a clamping plate 6, a sliding frame 7 and a driving screw 8. The sliding frame 7 slides on the clamping part, and a scale (not shown in the figure) is provided on the sliding frame 7. The clamping plate 6 is fixedly connected to the sliding frame 7, and the driving screw 8 is threadedly engaged with the clamping part. The distal end of the driving screw 8 is rotatably connected to the clamping plate 6, and a rubber anti-skid pad 9 is provided on the side of the clamping plate 6 facing the bent pipe 1.

In this state, the reset torsion spring 5 has a restoring torsion force, but under the action of the limiting arc plate 10, the clamping arc plate 4 cannot rotate. When the limiting arc plate 10 slides in a direction away from the clamping arc plate 4 until it is not in contact with the clamping arc plate 4, under the action of the reset torsion spring 5, the clamping arc plate 4 rotates in a direction away from the bent pipe 1, so the clamping assembly on the clamping arc plate 4 does not clamp the bent pipe 1.

[0028] An angle sensor 30 is provided on the rotating shaft of the two connecting rods 16, and the angle sensor 30 is used to measure the angle between the two connecting rods 16 on the same lifting arm 17. A height sensor is provided near the mounting seat 20 of each lifting arm 17, and a handheld terminal (not shown in the figure) is also provided. The height sensor 31 and the angle sensor 30 are connected to the handheld terminal via wireless Bluetooth. After the data of the height sensor 31 and the angle sensor 30 are transmitted to the handheld terminal, the corresponding data can be intuitively seen. It should be noted that a mobile power supply, a Bluetooth module for data transmission, and a controller are also provided; the mobile power supply supplies power to the above-mentioned sensors, Bluetooth modules and controllers, and the controller, sensors and Bluetooth modules are electrically connected. The controller is used to process the data of the sensors, and then the Bluetooth module transmits the data to the mobile terminal, wherein the height sensor 31, angle sensor 30, Bluetooth module, and controller mentioned are all prior art.

[0029] In other embodiments, the height sensor 31, the angle sensor 30, the handheld terminal, the mobile power supply and the controller may not be provided, and an angle ruler may be used to replace the angle sensor 30, and the inclination angle of the curved pipe 1 may be adjusted manually visually and then moved or installed in this state.

[0030] Based on this embodiment, the method and working principle of lifting the bent pipe 1 are as follows: Figure 1 As shown, the cutting plane A is the cross section of the center of the curved pipe 1, and the cutting plane B is the longitudinal section of the center of the curved pipe 1.

[0031] Step 1: Install the hoisting installation device of the present application on the elbow 1; The specific process is as follows: pre-adjust the angle of the central axis of the two clamping parts according to the bending angle of the curved pipe 1, then adjust each clamping assembly according to the diameter of the curved pipe 1 so that the clamping plate 6 reaches the position of clamping the curved pipe 1, then place the positioning arc plates 3 of the two clamping parts on the curved pipe 1, move the two positioning arc plates 3 so that the clamping plates 6 on the two positioning arc plates 3 are both adapted to the curved pipe 1, and then rotate each clamping arc plate 4 respectively so that the clamping arc plate 4 and the positioning arc plate 3 form a complete arc. During the rotation process, the clamping arc plate 4 first pushes the limiting arc plate 10 to slide until the clamping arc plate 4 contacts the positioning arc plate 3 and forms a complete arc plate. During this process, the first spring 12 of the limiting arc plate 10 continues to be compressed when sliding. When the clamping arc plate 4 contacts the positioning arc plate 3 and forms a complete arc plate, the limiting arc plate 10 is reset under the action of the first spring 12, and then the limiting arc plate 10 limits the rotation of the clamping arc plate 4.

[0032] In the above process, the value of the angle sensor 30 can be compared with the bending angle of the curved pipe 1 to determine whether the hoisting installation device of the present application is stably and correctly installed on the curved pipe 1.

[0033] Step 2: One hook 2 of the crane is hung with the lifting ring 18, and the other hook 2 is hung with the adjusting ring 19, and then the lifting is performed; When lifting, first lift the hook 2 connected to the lifting ring 18 until the elbow 1 is completely suspended. Since the lifting ring 18 is located at the intersection of the two lifting arms 17, when the elbow 1 is completely suspended, the inner side of the elbow 1 is vertically downward. By observing the values ​​of the two height sensors on the mobile terminal, it is possible to intuitively understand whether the elbow 1 is vertically downward. The values ​​of the two height sensors should be consistent. When installing this device on the pipeline, the installation is accurate by comparing the value of the angle sensor with the bending angle of the elbow. When the values ​​of the two height sensors are consistent during lifting, it can be known that the elbow is vertically bent downward. When the height difference of the two height sensors reaches the value corresponding to the pipeline inclination angle, it is known that the adjustment of the pipeline inclination angle is completed. When reaching the designated lifting position, the value of the height sensor can be used to determine whether there is a docking error between the pipeline and the pipeline to be docked, thereby improving the accuracy of pipeline lifting, ensuring the accuracy of installation docking, and improving the efficiency of pipeline docking installation.

[0034] In the above process, the slider 21 on the lifting arm 17 slides along the mounting seat 20, and the elastic shaft 23 on the slider 21 moves from the starting point of the annular groove 24 to the end point of the linear groove 25, so the driving shaft 22 does not rotate and the second spring is compressed.

[0035] Then, the hook 2 connected to the adjusting lifting ring 19 is lifted to adjust the state of the elbow 1. In this embodiment, the elbow 1 is adjusted to a horizontal state at one end and an inclined state at the other end. The angle between the two lifting arms 17 and the values ​​of the two height sensors can be used to determine whether the elbow 1 has reached the installation position.

[0036] Step 3: After completing the installation, remove the hoisting installation device of the present application; after hoisting the elbow 1 to the designated position and connecting it to the pipeline at its installation position, remove the hoisting installation device of the present application. The specific process is as follows: first, the hook 2 is lowered at the same time. Under the gravity of the lifting arm 17 and the action of the second spring, the slider 21 of the lifting arm 17 slides along the driving shaft 22. During the sliding process, the elastic shaft 23 moves from the spiral groove 26 to the annular groove 24. During this process, the driving shaft 22 rotates. Under the action of the gear set 27, the winding shaft 28 rotates, so that the wire rope 29 is wound on the winding shaft 28. Therefore, the sliding arc rod 11 pulls the limit arc plate 10 to move. When the limit arc plate 10 does not contact the clamping arc plate 4, under the action of the reset torsion spring 5 and the gravity of the clamping arc plate 4, the clamping arc plate 4 moves away from the elbow 1, so that the clamping assembly on the clamping arc plate 4 does not clamp the elbow 1. In this process, when the elastic shaft 23 moves from the end point of the spiral groove 26 to the end point of the annular groove 24, under the action of the first spring 12, the driving shaft 22 rotates in the opposite direction, so that the elastic shaft 23 returns to the starting position of the annular groove 24. At the same time, the limit arc plate 10 is reset. Then, the hook 2 is lifted upwards to remove the device of the present application from the bent pipe 1 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Within the technical scope disclosed by the present invention, technicians familiar with the technical field can make equivalent replacements or changes based on the technical scheme and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
