Description

Technical Field

[0001] This invention relates to the field of prefabricated water meter protective well technology, specifically a prefabricated water meter protective well and its installation method. Background Technology

[0002] When installing water meters outdoors, it is necessary to construct a water meter well with the well cover located on the ground and the well body buried underground. The water meter is installed in the water meter well. Initially, water meter wells were constructed on-site using bricks, which resulted in long construction periods and high labor costs. To overcome the above-mentioned shortcomings of brick-structured water meter wells, a prefabricated form of water meter well combining steel structure and concrete structure was designed. Existing prefabricated water meter wells require hoisting into the foundation pit to be installed during installation.

[0003] However, the existing hoisting methods mostly use cranes to lift the prefabricated water meter wells into the foundation pit where they are to be installed. But when using a crane to lift the prefabricated water meter wells, the wells sway back and forth, requiring manual support for positioning, making installation extremely inconvenient. Furthermore, it is difficult to keep the well opening level when using a crane. After placing the well in the foundation pit, soil needs to be added to the gap between the protective well and the foundation pit before moving the well to level the opening, which is time-consuming and labor-intensive. Summary of the Invention

[0004] This invention provides a prefabricated water meter protective well and its installation method, which can effectively solve the problems in the existing hoisting methods mentioned above. These methods often involve using a crane to hoist the prefabricated water meter well into the installation pit.

[0012] According to the above technical solution, the fixed clamping assembly is provided with pit protection components on both sides, and the pit protection components include protective sleeves; A protective sleeve is provided on the outside of the connecting frame. One end of the protective sleeve has an adapter thread hole. A protective screw is rotatably connected inside the protective sleeve by a thread. A top block is welded to the top of the protective screw, and a handle is welded to the outside of the top block. The protective well body is provided with protective plates on both sides, and sliding grooves are opened on both sides of the protective plates.

A toggle hole is provided on the top of the protective plate, and a toggle block is welded to the top of the sliding plate. The toggle block passes through the toggle hole.

[0013] According to the above technical solution, the diameter of the adapter wire hole is equal to the diameter of the fixing bolt, and the outer surface of the sliding plate and the inner wall of the sliding groove are both smooth planes.

[0014] According to the above technical solution, the installation method of the prefabricated water meter protection well has the following operation steps: S1. Move the installation device to the top of the protective well body, attach the hooks to the top of the protective well body, and control the hoisting motor to drive the winding roller to rotate synchronously, so that the wire rope drives the protective well body to rise and detach from the ground. S2. Control the extension end of the lifting cylinder to descend, so that the inner support frame and inner support rod enter the interior of the protective well body. Control the stabilizing motor, adjust the cone to squeeze the adjusting ear and the inner support rod to move outward, and stabilize and fix the protective well body. S3. Using the movable wheels, the push device is moved to the position of the foundation pit. The support screw is rotated to fix the lifting cylinder. The hoisting motor rotates in the opposite direction, the wire rope extends, and the protective well body is driven into the foundation pit. S4. Rotate the adjusting bolts to ensure that the clamping hoops on both sides are firmly attached to the top of the protective well body. Rotate the fixing screw and push the rod to push the fixing rod inside the fixing sleeve to extend outward, so that the fixing plate firmly presses against both ends of the top of the pit, thus completing the fixing of the protective well body. S5. Start the hoisting motor to loosen the wire rope, remove the hook from the protective well body, start the stabilizing motor, rotate the adjusting cone in the opposite direction, separate the stabilizing block from the inner wall of the protective well body, remove the fixing bolts from the connecting sleeve and connecting frame, push the telescopic rod to retract into the telescopic sleeve to separate the connecting sleeve from the connecting frame. S6. Using the fixing bolts and adapter screw holes, fix the protective sleeve on the connecting frame, rotate the protective screw rod so that the top block presses against the protective plate held in the hand on one side, fix the protective plate on the top side of the pit, assemble and connect multiple protective plates, and reinforce both ends of the top of the pit.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a hoisting stabilization component, the entire installation device is moved to the top of the protective well using casters. Hooks are attached to the top of the protective well, and the hoisting motor, driven by the sequential meshing of bevel gears, synchronously rotates the winding rollers, causing the wire rope to lift the protective well and detach it from the ground. When a wire rope becomes slack, causing uneven stress, a pressure sensor transmits data to the control center of the electric actuator. The output end of the electric actuator corresponding to the slack wire rope retracts, and the rollers pull the wire rope to tighten it, thus ensuring that the hooks at the bottom of each wire rope receive equal stress. This significantly improves hoisting stability. Simultaneously, the extended end of the lifting cylinder is lowered, and the inner support frame enters the protective well body. The stabilizing motor drives the adjusting cone to rotate, and the adjusting cone presses against the adjusting ear, causing the inner support rod to extend outward. This ensures that the stabilizing block firmly adheres to the inner wall of the protective well body. With the support of the stabilizing block, the protective well body is guaranteed not to sway during ascent and descent, keeping the water meter well opening in a horizontal state. This greatly improves the stability of the protective well body during installation, eliminating the need to add soil to the gap between the protective well and the foundation pit and then move the water meter well to keep the opening horizontal, thus saving manpower.

[0016] 2. Equipped with a fixed clamping assembly, after the protective well body is fully inserted into the foundation pit, align the clamping hoops with the top two sides of the protective well body, rotate the adjusting bolts to make the clamping hoops on both sides firmly attached to the top two sides of the protective well body, rotate the handle to drive the fixing screw to rotate, causing the lifting blocks at both ends of the fixing screw to move closer to each other, and push the push rod to push the fixing rod inside the fixing sleeve to extend outward, so that the fixing plate at the top of the fixing rod firmly presses against both ends of the top of the foundation pit. Utilizing the interaction force between the clamping hoops and the fixing plate, the protective well body can be firmly and stably fixed inside the foundation pit, ensuring that the protective well body will not shift during subsequent backfilling. At the same time, the fixing bolts can be removed from the connecting sleeve and connecting frame, separating the connecting sleeve from the connecting frame, and removing the separated device. The device can be flexibly disassembled, facilitating construction during backfilling.

[0017] 3. A foundation pit protection component is installed. By using fixing bolts and adapter screw holes, the protective sleeve is fixed to the connecting frame. By rotating the protective screw rod with the hand handle, the top block presses against the protective plate on one side, and the protective plate on one side is stably fixed to the top side of the foundation pit. By using the cooperation between the sliding plate and the sliding groove, multiple protective plates are assembled and connected to reinforce both ends of the top of the foundation pit, prevent the top of the foundation pit from collapsing, and bring convenience to the workers for subsequent work.

[0018] In summary, the hoisting stabilization assembly can center the protective well body, allowing it to be moved closer to the center of the pit when moving it inside. This makes the gap between the protective well body and the pit more uniform, facilitating the installation of the fixing clamping assembly and the pit protection assembly. The snap-fit ​​connectors on the outer plate of the fixing clamping assembly are embedded in the slots of the fixing plate. The addition of the outer plate increases the contact area with both sides of the pit, further enhancing the stability of the protective well body. At the same time, the protective plates in the pit protection assembly can prevent the top and sides of the pit from collapsing, ensuring the safety of personnel at the bottom of the pit.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1-10 As shown, the present invention provides an installation device for a prefabricated water meter protective well, including a protective well body 1. A hoisting and stabilizing assembly 2 is provided on the top of the protective well body 1. The hoisting and stabilizing assembly 2 includes a lifting cylinder 201, a support frame 202, a lifting platform 203, a hoisting motor 204, a winding roller 205, a bevel gear 206, a steel wire rope 207, a hook 208, a hoisting frame 209, a stabilizing motor 210, a drive shaft 211, a moving groove 212, a moving rod 213, a connecting spring 214, an inner support frame 215, a sliding frame 216, an inner support rod 217, an adjusting ear 218, a return spring 219, a stabilizing block 220, a rubber pad 221, a rubber ring 222, a moving wheel 223, a support screw 224, a support seat 225, an adjusting cone 226, an electric push rod 227, a mounting seat 228, a roller 229, and a pressure sensor 230. Lifting cylinders 201 are installed at the four corners of the top of the protective well body 1. A support frame 202 is installed on the top of the lifting cylinder 201. A lifting platform 203 is fixedly connected to the bottom of the support frame 202. A hoisting motor 204 is fixedly installed on one side of the top of the lifting platform 203. The input end of the hoisting motor 204 is electrically connected to the output end of an external power supply. Winding rollers 205 are installed around the top of the lifting platform 203. The rotation output end of the hoisting motor 204 is fixedly connected to one end of one winding roller 205. Bevel gears 206 are fixedly connected to both ends of the two winding rollers 205. Bevel gears 206 are fixedly connected to one end of the other two winding rollers 205. 6. The bevel gears 206 on two adjacent winding rollers 205 mesh with each other in sequence. A steel wire rope 207 is wound around the outside of the winding roller 205. The steel wire rope 207 passes through the lifting platform 203 and is connected to a hook 208. Grooves are opened at the four corners of the top of the protective well body 1. Several hooks 208 are respectively hooked into the grooves. The hoisting motor 204 drives the connected winding rollers 205 to rotate. Under the sequential connection of the bevel gears 206, all winding rollers 205 rotate synchronously. The winding rollers 205 then synchronously drive the outer wound steel wire rope 207 to rotate for winding and unwinding operations, so that the hooks 208 are hooked into the grooves. The protective well body 1 can rise and fall smoothly. A rubber ring 222 is installed at the joint between the wire rope 207 and the lifting platform 203. The rubber ring 222 reduces friction between the wire rope 207 and the lifting platform 203, preventing damage to the wire rope 207 during prolonged movement and providing protection. Electric actuators 227 are fixedly installed at the four corners of the top of the hoisting frame 209. The input end of the electric actuator 227 is electrically connected to the output end of an external power source. A mounting base 228 is installed at the output end of the electric actuator 227, and a rotating component is mounted inside the mounting base 228. Rollers 229 and wire ropes 207 pass through the interiors of adjacent mounting bases 228. A pressure sensor 230 is installed at the connection between the hook 208 and the wire rope 207. When a wire rope 207 becomes slack, causing uneven force, the pressure sensor 230 transmits data to the control center of the electric actuator 227. The output end of the electric actuator 227 corresponding to the slack wire rope 207 retracts, and the rollers 229 pull the wire rope 207 inward to tighten it. This ensures that the hooks 208 at the bottom of each wire rope 207 are subjected to the same force, preventing the aging and slack of the wire rope 207 from affecting the stability of the hoisting. A lifting frame 209 is installed at the bottom of the lifting platform 203. A stabilizing motor 210 is fixedly installed inside the lifting frame 209. The input end of the stabilizing motor 210 is electrically connected to the output end of an external power supply. The output end of the stabilizing motor 210 is connected to a drive shaft 211. A moving groove 212 is opened inside the drive shaft 211. A moving rod 213 is movably installed inside the moving groove 212. A connecting spring 214 connects the top end of the moving rod 213 and the top end of the moving groove 212. An adjusting cone 226 is fixedly installed at the bottom end of the moving rod 213. The moving groove 212 and the moving rod 213 are horizontally connected. The cross-sectional shape is a mutually fitting regular hexagon. When the stabilizing motor 210 drives the drive shaft 211 to rotate, the drive shaft 211 can drive the moving rod 213 in the moving groove 212 to rotate, thereby driving the adjusting cone 226 at the bottom of the moving rod 213 to rotate. An inner support frame 215 is fixedly installed at the bottom of the hoisting frame 209. Sliding frames 216 are installed around the inner support frame 215. Inner support rods 217 are slidably installed around the inner support frame 215. The top ends of the inner support rods 217 pass through the corresponding sliding frames 216. An adjusting lug 218 is welded to one end of the inner support rod 217, and an adjusting lug 218 is welded to the other end. A stabilizing block 220 has a rubber pad 221 bonded to one side. When the stabilizing block 220 contacts the protective well body 1, the rubber pad 221 acts as a buffer to prevent the stabilizing block 220 from damaging the inner wall of the protective well body 1. The side of the stabilizing block 220 is curved, allowing it to fit more closely to the inner wall of the protective well body 1. A return spring 219 connects the sliding frame 216 and the corresponding inner support rod 217. The inner side of the adjusting ear 218 is connected to the outer side of the adjusting cone 226 by a thread. The surface of the moving rod 213 and the inner wall of the moving groove 212 are both smooth surfaces. The cone 226 rotates within the adjusting ear 218, which expands the adjusting ear 218 outward, thereby driving the inner support rod 217 to move outward. This allows the stabilizing block 220 to fit tightly against the inner wall of the protective well body 1, fixing the protective well body 1 and preventing it from swaying during hoisting. When the adjusting cone 226 rotates in the opposite direction, the connecting spring 214 acts as a connector, gradually moving the adjusting cone 226 outward from the adjusting ear 218. Under the elastic action of the return spring 219, the inner support rod 217 returns to its original position, and the stabilizing block 220 separates from the protective well body 1. The bottom of the lifting cylinder 201 is equipped with a movable wheel 223. A support screw 224 is connected to one side of the movable wheel 223 by a threaded rotation. A support base 225 is welded to the bottom of the support screw 224. After the hook 208 and the stabilizing block 220 stably hoist and fix the protective well body 1, the movable wheel 223 can be used to move the protective well body 1 to the installation location for installation. By rotating the support screw 224, the entire device can be horizontally supported and fixed, so that the protective well body 1 can be stably and vertically placed in the pit. A fixing clamping assembly 3 is provided on the outside of the protective well body 1. The fixing clamping assembly 3 includes a telescopic sleeve 301, a positioning hole 302, a telescopic rod 303, a fixing hole 304, a positioning pin 305, a connecting sleeve 306, a connecting frame 307, a fixing bolt 308, a rotating seat 309, a fixing screw 310, a handle 311, a lifting block 312, a fixing sleeve 313, a fixing rod 314, a rotating seat 315, a pushing rod 316, a fixing plate 317, an outer plate 318, a slot 319, a clamping connector 320, a rotating disk 321, an adjusting bolt 322, a clamping clamp 323, and a limiting screw 324. Telescopic sleeves 301 are installed on both sides of the bottom of two adjacent support frames 202. Positioning holes 302 are evenly distributed on both sides of the telescopic sleeves 301. Telescopic rods 303 are slidably installed inside the telescopic sleeves 301. Fixing holes 304 are evenly distributed through one side of the telescopic rods 303. Positioning pins 305 are embedded inside the two positioning holes 302 and the fixing holes 304 on the telescopic sleeves 301 and the telescopic rods 303 on the same side. Connecting sleeves 306 are welded to the bottom of the telescopic rods 303. Connecting frames 307 are movably connected inside the connecting sleeves 306. The connecting sleeves 306 and the connecting frames 307 are connected by fixing bolts 308. The bottoms of two adjacent connecting frames 307... A rotating seat 309 is fixedly installed on the rotating seat 309. A fixing screw 310 is rotatably installed inside the rotating seat 309. A handle 311 is installed on the top of the fixing screw 310. Lifting blocks 312 are movably connected to both ends of the fixing screw 310 by threads. The threads at both ends of the fixing screw 310 rotate in opposite directions. A fixing sleeve 313 is fixedly installed on one side of the rotating seat 309. A fixing rod 314 is slidably installed inside the fixing sleeve 313. A rotating seat 315 is installed on the outer side of the top end of the fixing rod 314. A push rod 316 is rotatably connected between one lifting block 312 on the same side and one end of the rotating seat 315. A fixing plate 317 is installed on the top end of the fixing rod 314. The fixed plate 317 is connected to external plates 318 at both ends. Slots 319 are provided on both sides of the fixed plate 317. A connector 320 is provided on one side of the external plate 318, which is embedded in the slot 319. The slots 319 and connector 320 have a matching "T" shape in cross-section. The external plate 318 is movably connected to the slots 319 via the connectors 320 and the slots 319, allowing for flexible disassembly. The external plate 318 can reinforce both ends of the pit top, preventing collapse and ensuring convenient connection of water pipes. A rotating disk 321 is fixedly installed on the other side of the rotating base 309. The rotating disk 321 contains... An adjusting bolt 322 is rotatably connected. A clamping hoop 323 is threadedly connected to the outside of the adjusting bolt 322. The inner side of the clamping hoop 323 is tightly fitted to the top two sides of the protective well body 1. Limiting screws 324 are evenly installed on one side of the rotating disk 321. The clamping hoop 323 is aligned with the top two sides of the protective well body 1. The adjusting bolt 322 is rotated so that the clamping hoop 323 on both sides is firmly fitted to the top two sides of the protective well body 1. After the clamping hoop 323 is fixed, the fixing bolt 308 on the rotating disk 321 is rotated. The fixing bolt 308 presses the adjusting bolt 322 to limit the position of the adjusting bolt 322 and prevent the clamping hoop 323 from loosening due to the rotation of the adjusting bolt 322. The fixed clamping assembly 3 is provided with pit protection assembly 4 on both sides. The pit protection assembly 4 includes a protective sleeve 401, an adapter thread hole 402, a protective thread rod 403, a top block 404, a handle 405, a protective plate 406, a sliding groove 407, a sliding plate 408, a telescopic spring 409, a toggle hole 410, and a toggle block 411. A protective sleeve 401 is provided on the outer side of the connecting frame 307. One end of the protective sleeve 401 has an adapter thread hole 402. The diameter of the adapter thread hole 402 is equal to the diameter of the fixing bolt 308. When the protective well body 1 is stably fixed inside the pit, the fixing bolt 308 is removed from the connecting sleeve 306 and the connecting frame 307. The telescopic rod 303 is pushed into the telescopic sleeve 301 to retract, thus separating the connecting sleeve 306 from the connecting frame 307. After the telescopic rod 303 is fixed with the positioning pin 305, the fixing bolt 308 is inserted back into the connecting frame 307 and through the adapter thread hole 402. 02. The protective sleeve 401 is fixed on the connecting frame 307 to prepare for the subsequent fixing of the protective plate 406, so that the fixing bolt 308 can be used for different functions. The protective sleeve 401 is connected to the protective screw rod 403 through a threaded rotation. The top of the protective screw rod 403 is welded to the top block 404, and the outside of the top block 404 is welded to the handle 405. Protective plates 406 are set on both sides of the protective well body 1. Sliding grooves 407 are opened on both sides of the protective plate 406. A sliding plate 408 is slidably installed in the sliding groove 407 on one side. The outer surface of the sliding plate 408 is flush with the sliding groove 407. The inner walls are all smooth planes. A telescopic spring 409 is evenly connected between one side of the sliding plate 408 and the corresponding sliding groove 407. The sliding plate 408 inside one protective plate 406 is embedded in the sliding groove 407 on one side of an adjacent protective plate 406. A toggle hole 410 is provided at the top of the protective plate 406. A toggle block 411 is welded to the top of the sliding plate 408, passing through the toggle hole 410. Using the fixing bolt 308 and the adapter screw hole 402, the protective sleeve 401 is fixed to the connecting frame 307. The protective screw is rotated by hand using the handle 405. Rod 403 is moved out of the protective sleeve 401, so that the top block 404 presses against the protective plate 406 held by the worker on one side, and the protective plate 406 on one side is stably fixed to the top side of the pit. By using the cooperation between the sliding plate 408 and the sliding groove 407, the actuating block 411 is pulled to compress the telescopic spring 409, and multiple protective plates 406 are assembled and connected together. With the help of other top blocks 404, multiple connected protective plates 406 are fixed to both sides of the top of the pit, and the top of the pit is reinforced to prevent the top of the pit from collapsing.

[0023] like Figure 11 An installation method for a prefabricated water meter protection well, the operation steps of which are as follows: S1. Move the installation device to the top of the protective well body 1, attach the hook 208 to the top of the protective well body 1 around the perimeter, and control the hoisting motor 204 to drive the winding roller 205 to rotate synchronously, so that the wire rope 207 can drive the protective well body 1 to rise and detach from the ground. S2. Control the lifting cylinder 201 to descend, so that the inner support frame 215 and the inner support rod 217 enter the protective well body 1. Control the stabilizing motor 210, and the adjusting cone 226 to squeeze the adjusting ear 218 and the inner support rod 217 to move outward, so as to stabilize and fix the protective well body 1. S3. Using the moving wheel 223, the device is pushed to move the protective well body 1 to the pit position. The support screw 224 is rotated to fix the lifting cylinder 201. The hoisting motor 204 rotates in the opposite direction, the wire rope 207 extends, and the protective well body 1 is driven into the pit. S4. Rotate the adjusting bolt 322 to make the clamping hoops 323 on both sides firmly attached to the top two sides of the protective well body 1. Rotate the fixing screw 310 and push the push rod 316 to push the fixing rod 314 in the fixing sleeve 313 to extend outward, so that the fixing plate 317 firmly presses against the top two ends of the pit, thus completing the fixing of the protective well body 1. S5. The hoisting motor 204 is started, which loosens the wire rope 207. The hook 208 is removed from the protective well body 1. The stabilizing motor 210 is started, the adjusting cone 226 rotates in the opposite direction, and the stabilizing block 220 separates from the inner wall of the protective well body 1. The fixing bolt 308 is removed from the connecting sleeve 306 and the connecting frame 307. The telescopic rod 303 is pushed to retract into the telescopic sleeve 301, which separates the connecting sleeve 306 from the connecting frame 307. S6. Using the fixing bolts 308 and the adapter screw holes 402, fix the protective sleeve 401 on the connecting frame 307, rotate the protective screw rod 403 so that the top block 404 presses against the handheld protective plate 406 aligned on one side, fix the protective plate 406 on the top side of the pit, assemble and connect multiple protective plates 406 together, and reinforce both ends of the top of the pit.

[0024] The working principle and usage process of this invention are as follows: When installing the water meter protection well, push the lifting cylinder 201 to move the installation device directly above the protection well body 1. At this time, the extended end of the lifting cylinder 201 is in the extended state, and the inner support frame 215 is located directly above the well opening of the protection well body 1. Control the lifting cylinder 201 to lower the extended end of the lifting cylinder 201. When the inner support frame 215 enters the interior of the protection well body 1, the extended end of the lifting cylinder 201 stops lowering. Hooks 208 are then attached to the top of the protection well body 1 around the perimeter. The hoisting motor 204 is started, and the hoisting motor 204 drives the connected winding roller 2. 05 rotates, and under the sequential connection of the bevel gear 206, all the winding rollers 205 rotate synchronously. The winding rollers 205 then synchronously drive the outer winding wire rope 207 to rotate for winding operation. The rubber ring 222 installed at the joint between the wire rope 207 and the lifting platform 203 can reduce the friction between the wire rope 207 and the lifting platform 203 and protect the wire rope 207. Under the pulling action of the wire rope 207, the bottom of the protective well body 1 is separated from the ground, and the hoisting motor 204 is stopped. At this time, the protective well body 1 is in the hoisted state. When the stabilizing motor 210 is started, the stabilizing motor 210 drives the drive shaft 211 to rotate. The cross-sectional shape of the moving groove 212 and the moving rod 213 are mutually fitted regular hexagons. When the stabilizing motor 210 drives the drive shaft 211 to rotate, the drive shaft 211 can drive the moving rod 213 in the moving groove 212 to rotate, which in turn drives the adjusting cone 226 at the bottom of the moving rod 213 to rotate. The inner side of the adjusting ear 218 is connected to the outer side of the adjusting cone 226 by a thread. The adjusting cone 226 moves into the adjusting ear 218. The adjusting cone 226 rotates in the adjusting ear 218, expanding the adjusting ear 218 outward, which drives the inner support rod 217 to move outward. When the stabilizing block 220 is tightly attached to the inner wall of the protective well body 1, the stabilizing motor 210 stops running, and the stabilizing block 220 fixes the protective well body 1 to prevent the protective well body 1 from swinging around. The bottom of the lifting cylinder 201 is equipped with a movable wheel 223. A support screw 224 is connected to one side of the movable wheel 223 by a threaded rotation. A support base 225 is welded to the bottom of the support screw 224. After the hook 208 and the stabilizing block 220 stably hoist and fix the protective well body 1, the movable wheel 223 is used to push the device to move the protective well body 1 to the foundation pit where it is to be installed for installation. When the protective well body 1 is moved directly above the foundation pit, the support screw 224 is rotated according to the level of the ground to make the whole device in a horizontal and fixed state, so that the protective well body 1 can be stably and vertically placed inside the foundation pit. After the device is stably fixed, the extended end of the lifting cylinder 201 is controlled to descend. At the same time, the hoisting motor 204 is started. The hoisting motor 204 rotates in the opposite direction. Under the mutual meshing action between the bevel gears 206, the winding roller 205 is driven to rotate synchronously. The wire rope 207 extends and drives the protective well body 1 to descend stably into the foundation pit. When the protective well body 1 is completely inside the foundation pit, the hoisting motor 204 stops running. Align the clamping hoops 323 with the top sides of the protective well body 1, and rotate the adjusting bolts 322 to ensure that the clamping hoops 323 are firmly attached to the top sides of the protective well body 1. After the clamping hoops 323 are fixed, rotate the fixing bolts 308 on the rotating disk 321. The fixing bolts 308 press against the adjusting bolts 322 to limit the position of the adjusting bolts 322, preventing the clamping hoops 323 from loosening due to the rotation of the adjusting bolts 322. After the clamping hoops 323 are fixed, rotate the handle 311 to rotate the fixing screw 310. Under the action of the threaded connection, the two ends of the fixing screw 310 are raised. As the lowering blocks 312 approach each other, under the combined action of the push rod 316 and the rotating seat 315, the push rod 316 pushes the fixed rod 314 inside the fixed sleeve 313 to extend outward. When the fixed plate 317 at the top of the fixed rod 314 firmly presses against both ends of the top of the pit, the rotation of the fixed screw 310 stops, and the snap joint 320 on the outer plate 318 is embedded into the slot 319 through the slot 319. The increase of the outer plate 318 increases the contact area with both sides of the pit, further increasing the stability of the protective well body 1, and at the same time preventing the top of the pit from collapsing. After the protective well body 1 is fixed, the hoisting motor 204 is rotated to slack the wire rope 207, allowing the hook 208 to be removed from the protective well body 1. The stabilizing motor 210 is then started, driving the drive shaft 211 to rotate in the opposite direction. This, in turn, controls the adjusting cone 226 to rotate in the opposite direction. The reverse rotation of the adjusting cone 226 causes it to gradually move outward from inside the adjusting lug 218. Under the elastic action of the return spring 219, the inner support rod 217 returns to its original position. The stabilizing block 220 is separated from the inner wall of the protective well body 1. The fixing bolt 308 is removed from the connecting sleeve 306 and the connecting frame 307, and the positioning pin 305 is removed. The telescopic rod 303 is pushed into the telescopic sleeve 301 to retract, causing the connecting sleeve 306 to separate from the connecting frame 307. After fixing the telescopic rod 303 with the positioning pin 305, the fixing bolt 308 is inserted back into the connecting frame 307. The support screw 224 is rotated to separate the support seat 225 from the bottom surface. The driving wheel 223 pushes the lifting cylinder 201 to remove the separated device from the top of the pit, making it easier for subsequent workers to go down to the bottom of the pit to connect water pipes. After the separated device is removed, the protective sleeve 401 is fixed to the connecting frame 307 by using the fixing bolt 308 and the adapter thread hole 402. The protective screw 403 is rotated by hand handle 405 to move the protective screw 403 out of the protective sleeve 401, so that the top block 404 presses against the protective plate 406 held by the worker on one side, and the protective plate 406 on one side is stably fixed to the side of the top of the pit. By using the cooperation between the sliding plate 408 and the sliding groove 407, the actuating block 411 is pulled to compress the telescopic spring 409, assembling and connecting multiple protective plates 406 together. With the help of other top blocks 404, multiple connected protective plates 406 are fixed to both sides of the top of the pit, which reinforces the top of the pit and prevents the top of the pit from collapsing, which would cause inconvenience to the workers in connecting water pipes.
