Technical Field
[0001] This utility model relates to the field of disassembly tools, specifically a tool for disassembling the manhole cover of a drying cylinder. Background Technology
[0002] The drying cylinder manhole cover removal tool is a specialized tool for disassembling the manhole cover inside the drying cylinder equipment. This tool plays an indispensable role in the daily maintenance, regular inspection, and handling of sudden failures of the drying cylinder equipment. It can ensure the smooth progress of maintenance and inspection work, thereby effectively improving the operating efficiency of the drying cylinder equipment and extending its service life.
[0003] Traditionally, disassembling a manhole cover requires workers to first use tools to secure the bolts to prevent rotation during disassembly, and then use another tool to limit the nuts to prevent loosening or falling off. Only after these preparations can each nut be tightened one by one to gradually remove the cover from the equipment. This process is cumbersome, time-consuming, and requires significant time and effort, increasing the workload of workers and significantly reducing work efficiency, thus affecting overall work progress and equipment maintenance efficiency. Therefore, a new tool for disassembling manhole covers for drying cylinders is proposed. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a tool for disassembling the manhole cover of a drying cylinder, which effectively simplifies the disassembly process and significantly improves work efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for disassembling the manhole cover of a drying cylinder, comprising a sleeve, a connecting plate fixed to the top of the sleeve, a cover provided on the top of the connecting plate, and a disassembly assembly provided on the top of the cover; The disassembly assembly includes a ring that fits against the top of the pressure cap. The ring has multiple sets of circular grooves arranged in a circular array inside. A fixed sleeve is slidably connected to the lower end of the inner wall of each groove. Limiting plates are fixedly connected to both sides of the fixed sleeve. The ring has an arc-shaped groove inside for the movement of the limiting plates. A vertical rod is provided at the top of the fixed sleeve. A return spring is sleeved on the outer wall of the vertical rod inside the circular groove. A circular block is fixed to the top of the return spring and to the curved outer wall of the vertical rod. A circular sliding groove is opened at the top of the ring. A slider is slidably connected inside the circular sliding groove. An L-shaped rod is fixed to the top of the slider. A moving block is slidably connected inside the L-shaped rod. A rope is fixed to the top of the moving block, and a wrench is wound around the end of the rope away from the moving block.
[0006] As a preferred technical solution, multiple sets of mounting holes are provided on both the connecting plate and the pressure cover. Bolts are placed in the mounting holes, and nuts are installed on the bolts to fix the connecting plate and the pressure cover.
[0007] As a preferred technical solution, the number of internal grooves of the ring matches the number of mounting holes.
[0008] As a preferred technical solution, the lower end of the fixing sleeve is provided with a hexagonal groove that matches the bolt.
[0009] As a preferred technical solution, the top end of the vertical rod passes through the upper end of the circular ring and is slidably connected to it, and a knob is fixed at the top end of the vertical rod.
[0010] As a preferred technical solution, the L-shaped rod has a movable groove inside, the movable groove is slidably connected to the movable block, and a connecting spring is installed at the top of the movable block.
[0011] In summary, the present invention has the following main advantages: This invention places a ring on top of the cap, aligning the inner groove of the ring with the mounting holes on the cap. This allows the hexagonal groove at the lower end of the fixing sleeve to tightly engage with the bolt head. Then, by engaging a wrench with a set of nuts, the bolt head is prevented from rotating with the nut due to the hexagonal groove inside the fixing sleeve, allowing the nut to be easily unscrewed. This facilitates convenient operation and efficient cap disassembly, significantly improving work efficiency and reducing labor intensity. After disassembly, multiple bolts engage with the fixing sleeve. During installation, simply placing the ring and cap back in their original positions allows the bolts to directly embed into the mounting holes, enabling rapid cap installation. This greatly improves installation efficiency and demonstrates high practicality and reliability. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0015] The embodiments of this utility model will be described below based on its overall structure.
[0016] A tool for removing the manhole cover of a drying cylinder, such as Figures 1 to 6 As shown, it includes a sleeve 100, a connecting plate 110 fixed to the top of the sleeve 100, a pressure cap 120 provided on the top of the connecting plate 110, and a disassembly assembly 200 provided on the top of the pressure cap 120. The disassembly assembly 200 includes a ring 210 that fits against the top of the pressure cap 120. The ring 210 has multiple circular grooves 220 arranged in a circular array inside. A fixing sleeve 230 is slidably connected to the lower end of the inner wall of each groove 220. Limiting plates 240 are fixedly connected to both sides of the fixing sleeve 230. The ring 210 has an arc-shaped groove 241 inside for the limiting plates 240 to move. A vertical rod 250 is provided at the top of the fixing sleeve 230. A return spring 260 is sleeved on the outer wall of the vertical rod 250 inside the circular grooves 220. The top of the return spring 260 is fixed to the curved outer wall of the vertical rod 250. Block 270 and ring 210 have a circular groove 280 at the top. A slider 290 is slidably connected inside the circular groove 280. An L-shaped rod 291 is fixed at the top of the slider 290. A moving block 293 is slidably connected inside the L-shaped rod 291. A rope 294 is fixed at the top of the moving block 293. A wrench 296 is wrapped around the end of the rope 294 away from the moving block 293. The number of circular grooves 220 inside the ring 210 matches the number of mounting holes 121. The lower end of the fixing sleeve 230 has a hexagonal groove 231 that matches the bolt 130.
[0017] When it is necessary to remove the pressure cap 120, the ring 210 is placed on top of the pressure cap 120, so that the circular groove 220 inside the ring 210 corresponds one-to-one with the mounting hole 121 on the pressure cap 120. At this time, the hexagonal groove 231 at the lower end of the fixing sleeve 230 is aligned with the head of the bolt 130 in the mounting hole 121. By rotating the knob 251, the vertical rod 250 is rotated, and the vertical rod 250 drives the fixing sleeve 230 to rotate. Since the limiting plates 240 on both sides of the fixing sleeve 230 slide in the arc groove 241 inside the ring 210, The axial movement of the retaining sleeve 230 is restricted, thereby ensuring a tight engagement between the hexagonal groove 231 and the head of the bolt 130. Then, by engaging the wrench 296 with the nut 140 on a set of bolts 130, and turning the wrench 296 to tighten the nut 140, the bolt 130 will not rotate with the nut 140 because the head of the bolt 130 is limited by the hexagonal groove 231 inside the retaining sleeve 230. This allows the nut 140 to be easily unscrewed from the bolt 130. After the nut 140 is removed, the L-shaped rod 291 can be moved above the next set of nuts 140 by sliding the slider 290 within the circular groove 280. This process is repeated to disassemble each set of bolts 130 and nuts 140 sequentially. During disassembly, the return spring 260 consistently applies a downward force to the vertical rod 250, ensuring that the hexagonal groove 231 at the lower end of the fixing sleeve 230 fits tightly against the head of the bolt 130. This guarantees stability during disassembly and allows for better coordination with the wrench 296 to complete the nut removal process. The 140-degree twisting operation makes it convenient for workers to operate and can efficiently complete the disassembly of the cover 120, greatly improving work efficiency and reducing labor intensity. After disassembly, multiple sets of bolts 130 will engage with the fixing sleeve 230. During installation, the ring 210 and cover 120 can be placed back in their original positions, allowing the multiple sets of bolts 130 to be directly embedded into the mounting hole 121, thereby enabling the quick installation of the cover 120. This greatly improves installation efficiency and has high practicality and reliability.
[0018] Please refer to this carefully. Figure 1 and Figure 2 Both the connecting plate 110 and the pressure cover 120 have multiple sets of mounting holes 121. Bolts 130 are placed in the mounting holes 121, and nuts 140 are installed on the bolts 131 to fix the connecting plate 110 and the pressure cover 120.
[0019] By using bolts 130 and nuts 140 to make the connecting plate 110 and the pressure cap 120 more secure and reliable, they can withstand greater disassembly force, ensuring that the connecting plate 110 and the pressure cap 120 will not loosen or separate during disassembly, thus ensuring the smooth progress of the entire disassembly process.
[0020] Please refer to this carefully. Figures 3 to 5The top of the vertical rod 250 passes through the upper end of the ring 210 and is slidably connected to it, and a knob 251 is fixed at the top of the vertical rod 250.
[0021] By setting knob 251, the operator can easily rotate the vertical rod 250, which in turn makes it easier for the fixing sleeve 230 to be snapped into the bolt 130.
[0022] Please refer to this carefully. Figure 6 The L-shaped rod 291 has a moving groove 292 inside, which is slidably connected to the moving block 293. A connecting spring 295 is installed at the top of the moving block 293.
[0023] By setting the moving slot 292, a stable sliding track is provided for the moving block 293, ensuring that the moving block 293 can move in a straight line along a predetermined path when subjected to external force, without any deviation or jamming.
