The specific details are as follows: 1. When disassembling the manhole cover, the entire assembly is moved using the casters, allowing the support frame to move above the manhole cover. The winch is then activated to unwind the wire rope, causing the movable frame to move downwards. A positioning hook can be inserted into the drainage hole on the manhole cover, securing it. The winch then rewinds the wire rope, allowing the movable frame to move upwards. During this upward movement, the guide rod slides on the support frame, and the winch is powered by a battery, enabling the manhole cover to be removed. The support frame can then be moved to transport the manhole cover, allowing access to the manhole for further work. When installing the manhole cover, the support frame is moved so that the cover is above the manhole opening, allowing the wire rope to unwind and lower the cover for installation. This design allows for quick and easy disassembly of the manhole cover, facilitating its movement and subsequent installation, thus enhancing its practicality. 2. After removing the manhole cover, the support frame can be moved to one side of the manhole opening. At this point, a winch can be used to continue moving the movable frame downwards, causing the guide rod to move upwards. The upward movement of the guide rod pushes the connecting plate upwards via a push plate, which in turn moves the movable rod upwards, stretching the telescopic spring. The movable plate then moves one end of the pull rope upwards. The pull rope, made of steel wire, pulls the connecting block, causing the guide wheel to rotate, which in turn rotates the rotating rod. The rotation of the rotating rod then drives the cam to rotate, which in turn pushes the movable plate downwards, causing the movable rod to slide on the fixed plate and stretch the return spring. The upward movement of the movable frame then pushes the movable plate downwards, causing the rubber pad on the movable plate to contact the ground. The rubber pad helps to position the entire structure, preventing further movement. Therefore, during underground operations, the support frame is easily positioned after movement, preventing accidental movement and improving convenience and practicality.

[0018] The positioning assembly 2 includes two sets of movable rods 201 symmetrically slidably connected to both sides inside the support frame 1. A movable frame 202 is fixedly installed on the top of each set of two movable rods 201. A telescopic spring 203 is sleeved on the outside of each movable rod 201 below the movable frame 202. Both ends of the telescopic spring 203 are fixedly connected to the movable frame 202 and the support frame 1, respectively, to facilitate the reset of the movable rods 201 after movement. A connecting plate 204 is fixedly installed at the bottom of each of the two movable rods 201, and symmetrically installed on the top of the movable frame 107. There are guide rods 111, which are slidably connected to the support frame 1. Push plates 205 are fixedly installed on one side of each guide rod 111 below the two connecting plates 204. Moving the push plates 205 upwards can push the connecting plates 204 upwards. Pull ropes 206 are fixedly installed on one side of the bottom of each of the two movable frames 202.

[0019] Working principle: Before using this portable UHPC manhole cover removal device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 4As shown, when disassembling the manhole cover, the entire assembly is moved using the casters 103, causing the support frame 1 to move above the manhole cover. The winch 104 is then activated to unwind the wire rope 105, causing the movable frame 107 to move downwards. The positioning hook 110 can then be inserted into the drainage hole on the manhole cover, hooking the cover in place. Afterwards, the winch 104 can rewind the wire rope 105, allowing the movable frame 107 to move upwards. During this upward movement, the guide rod 111 slides on the support frame 1, and the winch is assisted by the battery. The machine 104 is powered so that the manhole cover can be removed. Then the movable support frame 1 can be used to transport the manhole cover. After the manhole cover is removed, it can be used to enter the well for operation. When installing the manhole cover, the movable support frame 1 makes the manhole cover above the well opening, so that the wire rope 105 can be unwound and the manhole cover can be lowered for installation. This allows the manhole cover to be quickly removed and is easy to move after removal, which facilitates the transportation of the manhole cover and the subsequent installation, thus improving its practicality. After the manhole cover is removed, the support frame 1 can be moved to one side of the manhole opening. At this time, the winch 104 can be used to continue to move the movable frame 107 downward, causing the guide rod 111 to move upward. The upward movement of the guide rod 111 pushes the connecting plate 204 upward through the push plate 205, which in turn drives the movable rod 201 upward to stretch the telescopic spring 203. The movable plate 208 drives one end of the pull rope 206 upward. The pull rope 206 is made of steel wire. The pull rope 206 can then pull the connecting block 215 to rotate the guide wheel 214, causing the rotating rod 213 to rotate. After rotation, the cam 216 rotates, which pushes the moving plate 208 to move downward, causing the moving rod 207 to slide on the fixed plate 102 and stretch the return spring 210. Then, the upward movement of the movable frame 107 can push the moving plate 208 to move downward, so that the rubber pad 209 on the moving plate 208 comes into contact with the ground. The rubber pad 209 can be used to position the whole and prevent the whole from moving again. Therefore, when the support frame 1 moves during downhole operations, it is easy to position it and prevent the support frame 1 from moving accidentally, thus improving convenience and practicality.
