[0002] Drainage ditch covers are widely used in municipal and residential areas. Their installation and replacement require frequent handling. The covers are mostly made of concrete or metal and are quite heavy. Manual handling is not only inefficient but also prone to causing injuries. With the increasing mechanization of construction, the demand for specialized drainage ditch cover handling devices is becoming more and more urgent in order to reduce labor intensity and improve operational safety. Currently, there are significant problems with the handling of drainage ditch covers. Traditionally, they are mostly handled by simple supports or manually. Simple supports are not stable and are prone to slipping during handling, posing a safety hazard. They lack length adjustment functions, making them unsuitable for operators of different heights or covers of different sizes, resulting in poor flexibility. Their structural strength is insufficient, leading to deformation after prolonged use and a short service life. Manual handling is inefficient and prone to minor bumps and knocks, threatening personal safety. Ultimately, this leads to poor adaptability and low safety. Therefore, this application designs a drainage ditch cover handling device to solve the above problems. Utility Model Content

A bearing seat 9 is installed at the upper end of the frame 4, and the upper end of the bearing seat 9 is fixedly connected to the lower end of the hinge seat 10. An extension tube 3 is slidably provided inside one side of the circular pipe 1, and a handle 2 is installed on one side of the extension tube 3. A guide groove is opened on the side wall of the circular pipe 1 at the lower end of the extension tube 3, and limit plates are installed at both ends of the guide groove. An adjustment component is slidably provided on the inner side of the two limit plates. A hook is installed at the lower end of the other side of the circular pipe 1, and a clamping component is provided at the lower end of the hook. The circular pipe 1 and the extension tube 3 form an operating lever, and the frame 4 and the movable wheels 8 enable the device to move. The bearing seat 9 cooperates with the hinge seat 10 to rotate the operating lever, and the clamping component grabs the cover and lifts it. Convenience of operation; the adjustment component consists of a slider 13 and two locking blocks 14. The slider 13 is fixedly installed on the lower end of the other side of the extension tube 3. Both ends of the slider 13 have cavities. The two locking blocks 14 are slidably installed inside the two cavities respectively. Multiple limiting holes are equidistantly opened on the inner side of the two limiting plates. The slider 13 slides with the extension tube 3, and the locking blocks 14 are locked into different limiting holes to fix the extension length of the extension tube 3, which facilitates the adjustment of the operating rod length and adapts to different operating needs. A spring is installed between the locking blocks 14 and the slider 13. A pull rope 11 is connected to the inner side of the locking blocks 14. A baffle is installed at the lower end of the handle 2.

[0016] Working principle: When using this utility model, push the device next to the ditch cover, pull the pull ring to drive the locking block 14 to compress the spring through the pull rope 11, so that the locking block 14 disengages from the limiting hole. Adjust the length of the extension tube 3 extending out of the round tube 1 according to the height of the operator or the position of the cover. Release the pull ring, and the spring pushes the locking block 14 into the corresponding limiting hole for fixation. When it is necessary to clamp the ditch cover, one person holds the handle 2, and another person operates the clamping component to open the clamp 12 at the lower arm to clamp the cover. After clamping the cover, the person holding the handle 2 presses the handle down forcefully. 2. Press down on handle 2 to rotate the round tube 1 around the hinge seat 10, and transmit the force to the upper arm 5 through the hook. The upper arm and lower arm are hinged together, which drives the clamp 12 to further clamp the cover plate. Hang the fixing chain 7 on the hook 6 to fix the operating lever, and push the frame 4 to transport the cover plate to the target position through the moving wheels 8. After arriving, remove the fixing chain 7, pull the handle 2 upward to release the clamp 12 and complete the transport. After use, retract the extension tube 3 and push the device to the storage place, ensuring that the moving wheels 8 are placed stably, and complete the entire operation process.
