[0002] With the continuous development and upgrading of urban infrastructure, the construction and maintenance of drainage ditches have gradually become an important part of urban management. During the installation and maintenance of drainage ditches, lifting equipment, as crucial equipment, is widely used for hoisting, transporting, and installing drainage ditch components. Traditional lifting equipment structures are typically large in size, inconvenient to operate, and difficult to adapt to drainage ditches of different sizes, posing challenges to construction efficiency and operational convenience. Therefore, designing a compact, adaptable, and easy-to-operate lifting equipment has become key to improving construction efficiency and reducing labor intensity.

[0003] Currently, common drainage ditch lifting devices generally consist of lifting rings, crossbeams, chains, and lifting plates. These devices are secured to the drainage ditch using connecting pins or other fixing devices and operated using lifting equipment. These devices typically employ simple connection structures, distributing the load evenly across the components through mechanical transmission. While the design of these devices often considers load-bearing capacity and stability, their large size and standardized design often limit their applicability to drainage ditches of varying sizes.

[0004] Existing drainage ditch lifting tools are often bulky, causing inconvenience when connecting to drainage ditches. Traditional lifting tool structures are often not well adapted to drainage ditches of different sizes, especially when the specifications of the drainage ditches vary greatly. The connection of the lifting tools is not flexible enough and is difficult, resulting in low installation and disassembly efficiency. Therefore, traditional lifting tools have significant limitations in operation, making it difficult to quickly connect to the drainage ditch, increasing the complexity and time cost of construction. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drainage ditch lifting device, which aims to improve the problem that traditional lifting devices are large in size and inconvenient to connect to drainage ditches.

[0011] The extension plate is slidably connected to a hanging plate on its outer wall, and the hanging plate has a locking groove inside.

[0012] As a further description of the above technical solution:

[0013] The limiting plate is internally slidably connected with a connecting pin, which passes through the inside of the hanging plate.

[0014] As a further description of the above technical solution:

[0015] The connecting pin is internally threaded with a bolt, and a cone is fixedly connected to one end of the bolt.

[0016] As a further description of the above technical solution:

[0017] A steel ball is slidably connected inside the connecting pin, and the steel ball is engaged with the locking groove.

[0018] As a further description of the above technical solution:

[0019] The cone is in contact with the outer wall of the steel ball.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the chain at the bottom of the crossbeam is first connected to the extension plate through the second lifting ring. Both the second lifting ring and the first lifting ring are reinforced with reinforcing plates to improve the connection strength.

[0030] 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.

[0031] Reference Figures 1-4This utility model provides an embodiment of a drainage ditch lifting device, comprising a crossbeam 1 and a drainage ditch body 2. A lifting ring 4 is fixedly connected to the top of the crossbeam 1, used to attach a crane or other lifting equipment for easy lifting operations. A second lifting ring 5 is fixedly connected to the bottom of the crossbeam 1. Both the second lifting ring 5 and the first lifting ring 4 have reinforcing components on one side to enhance the load-bearing capacity of the lifting device connection, ensuring it can withstand a large load during lifting. The drainage ditch body 2 is located at the bottom of the crossbeam 1, used to fix the drainage ditch structure and provide sufficient support. A slot 3 is provided inside the drainage ditch body 2, used to engage with an extension plate 7 to ensure the lifting device can firmly connect to the drainage ditch. A lifting assembly is provided at the bottom of the crossbeam 1, providing actual lifting functionality and ensuring the stability and ease of operation of the lifting device.

[0032] The lifting assembly includes a chain 6, one end of which is fixedly connected to the inside of the second lifting ring 5. The chain 6 is used to connect the lifting equipment through the second lifting ring 5, evenly distributing and transferring the weight to the lifting device, ensuring that the lifting device is not prone to slippage or instability during the lifting process. An extension plate 7 is fixedly connected to the other end of the chain 6, extending the length of the chain 6 to allow the lifting device to adapt to the lifting of drainage ditches of different sizes. A limit plate 9 is fixedly connected to the bottom of the extension plate 7, serving a positioning function to ensure a firm connection between the extension plate 7 and the drainage ditch body 2, and preventing the extension plate 7 from disengaging from the slot 3. The extension plate 7 engages with the slot 3, ensuring a secure connection between the extension plate 7 and the drainage ditch body 2, preventing slippage during lifting. The reinforcing assembly includes a reinforcing plate 8, one side of which is fixedly connected to one side of the first lifting ring 4, and the other side of which is fixedly connected to one side of the second lifting ring 5. The reinforcing plate 8 enhances the strength of the lifting ring connection, preventing bending or damage under heavy loads, and improving the stability and durability of the lifting device. The reinforcing plate 8 enhances the connection strength of the lifting ring, ensuring that the lifting device can withstand greater tensile force and working load, and adapt to different lifting needs.

[0033] Reference Figure 4 and Figure 5An extension plate 7 has a slidably connected hanging plate 10 on its outer wall. The hanging plate 10 is used to connect the lifting device to the fixed part of the drainage ditch. Its outer wall is slidably connected to the extension plate 7, allowing the hanging plate 10 to be adjusted as needed to accommodate drainage ditches of different sizes. A locking groove 11 is provided inside the hanging plate 10, which engages with a steel ball 15 to ensure a secure connection between the hanging plate 10 and the connecting pin 12, preventing the hanging plate 10 from loosening or shifting during hoisting. A connecting pin 12 is slidably connected inside the limiting plate 9, connecting the extension plate 7 and the hanging plate 10 to ensure that both parts are firmly fixed during hoisting. The connecting pin 12 passes through the hanging plate 10, allowing it to slide within the hanging plate 10, thus achieving stable adjustment between the hanging plate 10 and the extension plate 7. A bolt 13 is threaded inside the connecting pin 12, used to adjust the tightness of the connecting pin 12, ensuring stable operation during use and preventing instability during hoisting due to loosening. A cone 14 is fixedly connected to one end of bolt 13. The design of cone 14 helps to form a tighter fit with steel ball 15 during installation, thereby enhancing the locking force of connecting pin 12 and ensuring that the connection part of the lifting device is not easy to loosen. Steel ball 15 is slidably connected inside connecting pin 12. The sliding of steel ball 15 inside connecting pin 12 can adjust its position according to the shape of locking groove 11, ensuring that the various parts of the lifting device can be stably fitted under different usage conditions. Steel ball 15 is fitted into locking groove 11. After connecting pin 12 is locked by the action of bolt 13 and cone 14, steel ball 15 is firmly fixed in locking groove 11, thereby ensuring that the connection between lifting plate 10 and extension plate 7 is stable and reliable. Cone 14 fits against the outer wall of steel ball 15. The shape and material of cone 14 allow it to make close contact with steel ball 15, increasing the locking effect and preventing the various parts of the lifting device from loosening or shifting during lifting. The design of cone 14 optimizes the force distribution, enabling the connection part to bear the pressure evenly when a load is applied, thereby improving the safety and stability of the lifting device.

[0034] Working principle: When using this drainage ditch lifting tool, first adjust the appropriate size of the lifting plate 10 according to the drainage ditch body 2 to be lifted. Then insert the lifting plate 10 into the outer wall of the extension plate 7. When fixing the lifting plate 10, insert the connecting pin 12 into the limiting plate 9 and the lifting plate 10. Then rotate the bolt 13 to drive the cone 14 into the connecting pin 12. Then the outer wall of the cone 14 fits against the steel ball 15, driving the steel ball 15 to be embedded in the locking groove 11. Then the limiting plate 9 and the lifting plate 10 are connected and limited by the connecting pin 12, which achieves the effect of easy connection with the drainage ditch.

[0035] During the subsequent hoisting, the crane connects to the crossbeam 1 via lifting ring 4. Then, the chain 6 at the bottom of the crossbeam 1 connects to the extension plate 7 via lifting ring 5. Both lifting ring 5 and lifting ring 4 are reinforced by reinforcing plates 8 to improve the connection strength. Then, the extension plate 7 is embedded into the slot 3 on the drainage ditch body 2, so that the lifting plate 10 fits into the opening on the drainage ditch body 2. Then, the lifting device can be connected to the drainage ditch body 2, achieving the effect of facilitating connection with the drainage ditch.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
