Description

Technical Field

[0001] The present application relates to the field of municipal road drainage pipe installation technology, and in particular to a municipal road drainage pipe installation device and an installation method thereof. Background Art

[0002] In recent years, the acceleration of urbanization and the continuous growth of population have put forward higher requirements for the construction and renewal of urban infrastructure. Among them, municipal drainage pipes, as an indispensable part of urban life, play an important role in drainage, water control and environmental protection. Drainage pipes refer to the system composed of pipes and ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. Urban drainage facilities are of great significance to urban construction.

[0003] Existing municipal drainage pipe installation equipment often requires the pipes to be hoisted into the trench in advance for placement. This way, the pipes come into contact with the soil, which will cause the pipe joints and the surface of the joints to be stained with mud or dust. Before the pipes are connected, the mud and dust at the adhesion points need to be cleaned manually, and then glue or lubricant is applied before manual docking. In addition, before the pipes are aligned and installed, soil needs to be filled around the pipes to fix them. All of these need to be done manually, which will waste a lot of installation time and manpower and material resources, and may cause a series of inconveniences such as delays in project progress. Summary of the Invention

[0004] In order to improve the problem of manual cleaning of dirt and dust at the pipe mouth and manual burying of the pipe edge before installation, which causes waste of installation time, the present application provides a municipal road drainage pipe installation device and an installation method thereof.

[0005] The municipal road drainage pipe installation device and installation method provided in this application adopt the following technical solutions:

[0006] A municipal road drainage pipe installation device includes a frame that moves in an excavated trench, and a plurality of inclined guide rods for guiding and limiting the pipes are symmetrically arranged on the upper part of the inner cavity of the frame. A plurality of motors are relatively arranged on both sides of the bottom of the frame, and a reciprocating screw is fixed to the output end of the plurality of motors. A plurality of cleaning mechanisms with the same structure and used to support the pipes are arranged on one side of the plurality of reciprocating screws. The cleaning mechanisms are used to scrape and clean dust on the surface of the pipes and apply lubricant to the docking interfaces. A plurality of mobile landfill mechanisms with the same structure and used to fix the landfill piles on both sides of the bottom of the pipes are arranged on one side of the reciprocating screw. The mobile landfill mechanism is used to push the treated pipes for docking and fixation.

[0007] By adopting the above technical solution, it is possible to achieve guidance and limitation of the pipeline, ensuring the straightness and position accuracy of the pipeline during installation. At the same time, the design of the cleaning mechanism enables the dust on the surface of the pipeline to be effectively scraped off, and the lubricant is evenly applied at the interface, thereby improving the sealing and stability of the pipeline docking. The mobile landfill mechanism can automatically fill and fix both sides of the bottom of the pipeline, reducing manual operations and improving construction efficiency.

[0008] Preferably, the cleaning mechanism includes a first spur gear fixedly arranged on the reciprocating screw, a second spur gear is meshed with one side of the first spur gear, a transmission assembly for transmission is provided on one side of the second spur gear, a grinding wheel for driving the pipe to rotate is fixed on one side of the transmission assembly, and a roller for applying lubricant to the joint of the pipe is fixed on one side of the grinding wheel.

[0009] By adopting the above technical solution, the cleaning mechanism realizes the synchronous rotation of the grinding wheel and the roller through gear transmission, so that the dust on the surface of the pipe is effectively scraped off during the rotation process, and the lubricant is evenly applied at the joint. This design not only improves the cleaning efficiency, but also ensures the accuracy and uniformity of the lubricant application, providing good conditions for pipe docking.

[0010] Preferably, one side of the roller is provided with a scraper and a cleaning strip for scraping dust and cleaning the pipe interface, one side of the scraper is fixedly provided with a storage bin fixedly connected to the frame and used to store lubricant, and one side of the storage bin is fixedly provided with a funnel for adding lubricant.

[0011] By adopting the above technical solution, the provision of scrapers and cleaning strips further enhances the cleaning effect of the cleaning mechanism on the pipe interface, ensuring a clean and tidy interface. The storage bin and funnel design facilitates the storage and addition of lubricant, ensuring a continuous and stable supply of lubricant to the roller, ensuring the continuity and stability of lubricant application.

[0012] Preferably, an L-shaped fixing plate for supporting the first spur gear, the second spur gear, the transmission assembly and the grinding wheel is fixed on one side of the storage bin, and a special-shaped supporting plate for supporting the pipeline is fixed on one side of the L-shaped fixing plate.

[0013] By adopting the above technical solution, the L-shaped fixed plate provides stable support for the gear transmission assembly and the grinding wheel, ensuring that the grinding wheel can drive the pipeline to rotate normally. The special-shaped support plate effectively supports the pipeline, preventing the pipeline from shaking and deflecting during the cleaning process, thereby improving the accuracy and stability of cleaning.

[0014] Preferably, the mobile landfill mechanism includes a special-shaped scraping shovel that movably penetrates through a reciprocating lead screw. One side of the special-shaped scraping shovel is provided with an inclined surface shovel blade for shoveling soil to landfill and fix both sides of the bottom end of the pipeline.

[0015] By adopting the above technical solution, the design of the special-shaped scraping shovel and the inclined surface shovel blade enables the mobile landfill mechanism to automatically shovel soil and landfill and fix both sides of the bottom of the pipeline, reducing manual operation and improving construction efficiency. At the same time, the shape design of the inclined surface shovel blade makes the soil shoveling smoother and the landfill more compact, improving the stability of the pipeline.

[0016] Preferably, one side of the special-shaped scraping shovel is provided with a horizontal sliding groove opened on the side of the bottom cross beam of the vehicle frame. One side of the inner cavity of the horizontal sliding groove is slidably provided with a special-shaped sliding block for supporting and limiting the pipeline. An arc-shaped receiving groove for supporting and limiting the pipeline is opened on one side of the special-shaped sliding block.

[0017] By adopting the above technical solution, the design of the horizontal sliding groove and the special-shaped sliding block enables the pipeline to be effectively supported and limited during the process of moving and filling soil, preventing the pipeline from shaking and deviating. The shape design of the arc-shaped receiving groove matches the outer shape of the pipeline, improving the stability and accuracy of the support.

[0018] Preferably, a horizontal connecting rod for driving the special-shaped sliding block to move is fixedly arranged on one side of the special-shaped sliding block in the inner cavity of the horizontal sliding groove. An abutting block for abutting against the special-shaped scraping shovel and driving the horizontal connecting rod to move is fixedly arranged on one side of the horizontal connecting rod.

[0019] By adopting the above technical solution, the design of the horizontal connecting rod and the abutting block enables the special-shaped sliding block to move synchronously with the movement of the special-shaped scraping shovel, realizing continuous support and limitation of the pipeline.

[0020] Preferably, a compression spring fixedly connected to the horizontal sliding groove is sleeved on one side of the horizontal connecting rod where the special-shaped sliding block is located. The compression spring is used to reset the special-shaped sliding block.

[0021] By adopting the above technical solution, the compression spring can enable the special-shaped sliding block to automatically reset after the movement and filling of soil are completed, preparing for the next push of the pipeline for docking.

[0022] Preferably, a plurality of shock absorbers for buffering are symmetrically arranged at the bottom of the vehicle frame. Wheels are arranged on one side of each of the plurality of shock absorbers.

[0023] By adopting the above technical solution, the shock absorbers and the wheels can provide an effective buffering effect during the movement of the vehicle frame, reducing the bumps caused by uneven ground. At the same time, the setting of the wheels enables the vehicle frame to move conveniently in the excavation trench, improving construction efficiency and flexibility.

[0024] An installation method, applied to the above-mentioned municipal road drainage pipe installation device, includes the following steps:

[0025] S01. With the help of a crane, lift the pipe above the inclined guide rod and then slowly place it at the bottom of the inner cavity of the vehicle frame along the inclined guide rod. At this time, the end of the pipe that needs to be coated with lubricant abuts against the arc surface of the scraper, and the other end abuts against the arc surface of the arc-shaped receiving groove on one side of the special-shaped slider. After the pipe is placed stably, remove the lifting rope;

[0026] S02. Subsequently, turn on the motor control switch. The motor rotates to drive the reciprocating screw fixed to the output end to rotate. The rotation of the reciprocating screw drives the first straight gear to rotate. Through the meshing of the first straight gear and the second straight gear, the second straight gear rotates synchronously. The second straight gear drives the transmission component rotatably arranged on the cross bar of the L-shaped fixed plate to rotate, and transmits the power to the grinding wheel fixedly arranged on one side of the transmission component. Since the grinding wheel abuts against the outer ring surface of the pipe and the outer ring surface is provided with rubber strips to increase friction, the pipe is driven to rotate;

[0027] S03. While the grinding wheel drives the pipe to rotate, the grinding wheel drives the roller to rotate on the storage bin. The rotating roller adsorbs the lubricant in the storage bin and coats it on the outer ring surface of the pipe. Before applying the lubricant, the scraper and the cleaning strip arranged at the lower end of the roller first process the outer ring surface of the pipe. The scraper scrapes the dust on the pipe, and the cleaning strip wipes and cleans the surface after scraping to ensure that the ring surface at the butt joint of the pipe is clean for subsequent lubricant application;

[0028] S04. The rotation of the reciprocating screw drives the special-shaped scraper connected to it by thread to move reciprocally. When the special-shaped scraper moves towards the abutting block, the inclined surface scraper on it shovels up the soil on both sides of the pipe to fill the bottom and both sides of the pipe, playing a role of supporting and fixing. When the special-shaped scraper moves and abuts against the abutting block, it pushes the abutting block to move synchronously. The abutting block drives the cross link to move, and the cross link drives the special-shaped slider to drive the pipe to move synchronously through the arc-shaped receiving groove, so that the pipe is butted and sealed and fixed with the previously installed pipe. Under the action of the compression spring, when the special-shaped scraper moves in the opposite direction, the special-shaped slider, the cross link and the abutting block will be pushed back to their original positions, and then the reset is realized, waiting for the next operation. In this way, the installation work of the drainage pipe is completed.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The lower scraper of the roller in the cleaning mechanism and the cleaning strip are used to process the outer ring surface of the pipeline first, and then the roller adsorbs lubricant for coating, ensuring the cleanliness and lubrication of the butt joint surface. At the same time, the mobile landfill mechanism fills and supports the soil during pipeline installation, reducing manual soil filling operations, saving a large amount of installation time, manpower and material resources, avoiding delays in the project progress, and effectively solving the problem that the existing installation equipment requires manual cleaning of pipeline soil and dust through the coordinated cooperation of the cleaning mechanism and the mobile landfill mechanism;

[0031] 2. After the pipeline is lifted above the inclined guide rod by a crane and then falls into the inner cavity of the vehicle frame, the cleaning mechanism automatically cleans and lubricates the pipeline. The special-shaped scraper in the mobile landfill mechanism shovels, fills and supports the soil, and promotes the butt joint of the pipeline. There is no need for multiple manual operations, improving the installation efficiency and reducing the labor cost. Furthermore, the cooperation between the crane and the vehicle frame realizes the precise placement of the pipeline. Combining the cleaning mechanism and the mobile landfill mechanism overcomes the inconvenience of the existing equipment that requires manual cleaning and butt joint of the pipeline;

[0032] 3. The motor drives the reciprocating lead screw to rotate, enabling the cleaning mechanism to clean and lubricate the pipeline. The special-shaped scraper in the mobile landfill mechanism reciprocates to fill and support the soil and promote the butt joint of the pipeline. With the automatic coordinated work of each mechanism, manual intervention is reduced, installation time is saved, and the project progress is guaranteed. At the same time, the motor drives the reciprocating lead screw, linking the cleaning mechanism and the mobile landfill mechanism to solve the problems of cumbersome manual operation and low efficiency of the existing installation equipment.

[0045] An embodiment of this application discloses a municipal road drainage pipe installation device and its installation method

[0046] Embodiment 1

[0047] Referring to Figure 1 , Figure 2 , a municipal road drainage pipe installation device includes a vehicle frame 100 and shock absorbers 101 provided at the four corners of the bottom of the vehicle frame 100 for reducing bumps caused by uneven ground during movement. And at the lower end of one side of each shock absorber 101 at the four corners of the vehicle frame 100, wheels 102 are provided. Under the action of the wheels 102, the vehicle frame 100 can drive the entire device to move at the bottom of the inner cavity of the excavated excavation trench 108. And on the upper cross beam inside the vehicle frame 100, two symmetrically arranged inclined guide rods 105 are fixedly provided. The surfaces of the two inclined guide rods 105 facing each other are inclined inwards, so that the pipeline 106 can fall into the inner cavity of the vehicle frame 100 through the inclined surfaces of the inclined guide rods 105 and come into contact with the cleaning mechanism 200 and the mobile landfill mechanism 300. And on one side of the upper end surfaces of the two cross beams at the bottom of the vehicle frame 100, two relatively arranged motors 103 are fixedly provided. And both of the two motors 103 are permanent magnet synchronous motors 103. And at the output end of each motor 103, a reciprocating lead screw 104 is connected by a coupling, thereby driving the cleaning mechanism 200 and the mobile landfill mechanism 300 to operate

[0048] It should be noted that the shock absorber 101, the wheel 102, the motor 103, and the reciprocating lead screw 104 are all existing mechanisms, and their structural principles will not be elaborated here. The shock absorber 101 can adopt the DFBD Hongyan New King Kong cab spring shock absorber 5004-510125 of Hubei Baidi Automobile Technology Co., Ltd., and the motor 103 can adopt the HIM series permanent magnet synchronous motor. However, since they are existing mechanisms, they will not be described in detail here.

[0049] The shock absorbers 101 provided at the four corners of the bottom of the vehicle frame 100 cooperate with the wheels 102, enabling the device to move smoothly to a suitable position within the excavation groove 108; the inclined guide rods 105 symmetrically arranged on the upper cross beam of the inner cavity of the vehicle frame 100 guide the pipeline 106 to slide into the inner cavity and contact the cleaning mechanism 200 and the mobile landfill mechanism 300; while the permanent magnet synchronous motors 103 oppositely arranged on one side of the upper end surfaces of the bottom two cross beams drive the reciprocating lead screw 104 to rotate through a coupling, providing power for the cleaning mechanism 200 to clean and lubricate the pipeline 106 and the mobile landfill mechanism 300 to fix and dock the pipeline 106, and completing the installation of the drainage pipe under the coordinated cooperation of the two mechanisms.

[0050] Refer to Figures 3-8 , and several cleaning mechanisms 200 are provided on one side of several reciprocating lead screws 104, and the structures and installation methods of several mobile landfill mechanisms 300 are the same. The internal structures of the cleaning mechanisms 200 cooperate with each other to be able to scrape and clean the dust on the surface of the butting joint of the pipeline 106, and at the same time be able to apply a lubricant to the surface of the butting joint of the pipeline 106.

[0051] Refer to Figures 3-8 , and the cleaning mechanism 200 includes a first straight gear 201 fixedly and penetratingly arranged on the reciprocating lead screw 104, and the first straight gear 201 is rotatably arranged at the bottom of one side surface of the L-shaped fixing plate 210. One end of the reciprocating lead screw 104 penetrating the first straight gear 201 movably penetrates the L-shaped fixing plate 210, and the L-shaped fixing plate 210 is fixedly welded to the bottom cross beam of the vehicle frame 100. At the same time, a second straight gear 202 rotatably arranged on the L-shaped fixing plate 210 is meshed with the upper part of the first straight gear 201, and a transmission component 203 composed of a pulley and a belt is arranged on one side of the second straight gear 202. Furthermore, the rotation of the reciprocating lead screw 104 driving the first straight gear 201 is transmitted to drive the second straight gear 202 to rotate, so that the grinding wheel 204 fixedly arranged on one side of the transmission component 203 rotates accordingly.

[0052] Refer to Figures 3-8, on the side of the grinding wheel 204 away from the transmission component 203, a roller 205 is fixedly arranged. The outer ring surfaces of the roller 205 and the transmission component 203 are both in contact with the outer ring surface of the pipeline 106. And the outer ring surface of the grinding wheel 204 is provided with horizontal strip-shaped rubber strips to further increase the friction between the grinding wheel 204 and the pipeline 106, so that the grinding wheel 204 can drive the pipeline 106 to rotate.

[0053] Refer to Figures 3-8 , and the roller 205 is rotatably arranged at the upper end of one side of the storage bin 206. And the inner cavity of the storage bin 206 is used to store lubricating oil. The outer ring surface of the roller 205 is a soft brush made of oil-absorbing material. Then when the grinding wheel 204 drives the roller 205 to rotate, the roller 205 can adsorb the internal lubricant while rotating in the storage bin 206, and then roll and smear on the surface of the pipeline 106, so as to evenly smear the grease at the butting joint of the pipeline 106.

[0054] Refer to Figures 3-8 , and a scraper 207 is arranged at the lower end of the roller 205. And the scraper 207 is fixedly connected to the storage bin 206. At the same time, one side of the scraper 207 is in contact with the outer ring surface of the interface of the pipeline 106. Then it is used to scrape the dust on the surface of the butting joint of the pipeline 106. And a number of cleaning strips 208 with the same structure are fixedly arranged on the arc surface of the scraper 207. And a number of cleaning strips 208 are in contact with the outer ring surface of the pipeline 106. Then the surface of the pipeline 106 cleaned by the scraper 207 is cleaned again by the cleaning strips 208, so that the surface of the pipeline 106 can have a relatively clean surface when applying lubricant next, so that the lubricant is smeared more evenly, thereby increasing the lubrication effect and making the subsequent docking smoother.

[0055] Refer to Figures 3-8 , and a funnel 209 for adding lubricant is fixedly arranged at the upper end of one side of the storage bin 206. And the funnel 209 is communicated with the inner cavity of the storage bin 206. And a transparent observation window made of acrylic board is arranged on the upper surface of the storage bin 206 to observe the lubricant added therein. And a special-shaped support plate 211 is fixedly arranged at the lower end of one side of the L-shaped fixing plate 210 where the grinding wheel 204 is located. And the special-shaped support plate 211 is used to support the pipeline 106. The side of the special-shaped support plate 211 in contact with the pipeline 106 is set to be arc-shaped and fits the outer ring surface radian of the pipeline 106. At the same time, the arc surface on the special-shaped support plate 211 is the same as the arc surface of the scraper 207, and the height is also the same.

[0056] It should be noted that the highest liquid level of the lubricant contained in the storage bin 206 exceeds the bottom of the roller 205, so that when the roller 205 rotates, it can continuously absorb the lubricant to smear the surface of the pipeline 106. The widths of the roller 205 and the scraper 207 are the same as the docking width of the pipeline 106, and the width should be set to not less than fifteen centimeters.

[0057] The output end of the motor 103 rotates to drive the reciprocating lead screw 104 to rotate synchronously. Then, the rotation of the reciprocating lead screw 104 drives the first straight gear 201 to rotate. While the first straight gear 201 rotates, it drives the second straight gear 202 meshed on one side of it and arranged on the L-shaped fixing plate 210 to rotate synchronously. Thus, the transmission component 203 also rotatably arranged on the cross bar of the L-shaped fixing plate 210 on one side of the second straight gear 202 rotates. Then, the power is transmitted to the grinding wheel 204 fixedly arranged on one side of the transmission component 203. Since the grinding wheel 204 can be in fit and abutment with the outer ring surface of the pipeline 106, when the transmission component 203 rotates to drive the grinding wheel 204 to rotate, the grinding wheel 204 increases the friction with the outer ring surface of the pipeline 106 through the rubber strip arranged on its outer ring surface, thereby driving the pipeline 106 to rotate.

[0058] While the grinding wheel 204 drives the pipeline 106 to rotate, the grinding wheel 204 also drives the roller 205 fixedly arranged on one side of it to rotate on the storage bin 206. Thus, while the roller 205 rotates, it adsorbs the lubricant in the storage bin 206 and smears it on the outer ring surface of the pipeline 106. Before smearing the lubricant, the scraper 207 and the cleaning strip 208 arranged at the lower end of the roller 205 are responsible for scraping the dust on the pipeline 106 and wiping and cleaning the surface after scraping respectively, so that the outer ring surface of the butt joint of the pipeline 106 is cleaned, and then the lubricant is smeared.

[0059] Refer to Figures 3-6 As shown in [reference], a mobile landfill mechanism 300 is arranged between the reciprocating lead screw 104 and the cleaning mechanisms 200 arranged on both sides of the bottom cross beam of the vehicle frame 100. The mobile landfill mechanisms 300 are symmetrically arranged on the cross beams on both sides of the bottom of the vehicle frame 100, and the structures between the mobile landfill mechanisms 300 are the same and can be used to landfill the soil piles 107 on both sides of the bottom of the pipeline 106, thereby realizing the support and fixation of the pipeline 106, so that the pipeline 106 can be on the same horizontal line as the already connected part, which is convenient for subsequent docking.

[0060] Refer to Figures 3-6, and the mobile landfill mechanism 300 includes a special-shaped scraping shovel 301 movably penetrating through the reciprocating screw rod 104, and the special-shaped scraping shovel 301 is slidably arranged with the bottom cross beam of the vehicle frame 100. Furthermore, during the process of the reciprocating screw rod 104 driving the special-shaped scraping shovel 301 to reciprocate, the special-shaped scraping shovel 301 is guided and limited. On the opposite side of the special-shaped scraping shovel 301, there is an inclined surface shovel 302 that contacts the soil surface and can shovel the soil. Furthermore, during the movement process, the two sides at the bottom end of the pipeline 106 are landfilled to achieve support and fixation.

[0061] Refer to Figures 3-6 , and a horizontal sliding groove 308 is opened on the side surface of the bottom cross beam of the vehicle frame 100. And a baffle is arranged outside the horizontal sliding groove 308 to block the soil scraped by the special-shaped scraping shovel 301. On the side of the inner cavity of the horizontal sliding groove 308 away from the special-shaped scraping shovel 301, a special-shaped sliding block 303 is slidably arranged. And the surfaces of the special-shaped sliding block 303 and the horizontal sliding groove 308 are both set as smooth surfaces, thereby increasing the sliding effect while reducing wear. On the side of the special-shaped sliding block 303 located at the special-shaped scraping shovel 301, an arc-shaped receiving groove 304 is opened. And the radian of the arc-shaped receiving groove 304 can be mutually attached and abutted against the outer ring surface of the pipeline 106, thereby realizing the support and limitation of the pipeline 106.

[0062] Refer to Figures 3-6 , a horizontal connecting rod 305 with a length greater than half of the reciprocating screw rod 104 is fixedly arranged on the surface of one side of the inner cavity of the horizontal sliding groove 308 of the special-shaped sliding block 303. And at the end of the horizontal connecting rod 305 away from the special-shaped sliding block 303, there is a contact block 306 that protrudes from the inner cavity of the horizontal sliding groove 308 and can abut against the special-shaped scraping shovel 301. Furthermore, when the special-shaped scraping shovel 301 moves and abuts against the contact block 306, the contact block 306 is driven to move, so that the contact block 306 drives the horizontal connecting rod 3 and the special-shaped sliding block 303 to move. At the same time, the special-shaped sliding block 303 will drive the pipeline 106 to move and dock with other already installed pipelines 106. A compression spring 307 is sleeved on the outer ring surface of the horizontal connecting rod 305 on the side of the special-shaped sliding block 303. And one end of the compression spring 307 away from the special-shaped sliding block 303 is fixed to the inner cavity of the horizontal sliding groove 308, and the other end of the compression spring 307 abuts against the surface of the special-shaped sliding block 303. Furthermore, when the special-shaped sliding block 303 moves, the compression spring 307 is compressed, so that the compression spring 307 stores energy, and then waits to push the special-shaped sliding block 303 back to its original position.

[0063] The rotation of the output end of the motor 103 drives the reciprocating lead screw 104 to rotate, thereby driving the special-shaped scraping shovel 301 threadedly connected thereto to move reciprocally. When the special-shaped scraping shovel 301 moves towards the abutting block 306, the inclined surface shovel 302 provided on the special-shaped scraping shovel 301 will scoop up the soil on both sides of the pipeline 106. The scooped-up soil can support and fix the bottom of the pipeline 106. When the special-shaped scraping shovel 301 moves to the abutting block 306, it will push the abutting block 306 to move together, so that the abutting block 306 can drive the cross connecting rod 305 fixedly connected thereto to move. During the movement of the cross connecting rod 305, it will drive the special-shaped slider 303 fixedly connected thereto to move, and drive the pipeline 106 to move through the arc-shaped receiving groove 304 provided on one side of the special-shaped slider 303, so that the pipeline 106 can be butted, sealed and fixed with the previously installed pipeline 106. When the special-shaped scraping shovel 301 moves in the opposite direction, under the action of the compression spring 307, the special-shaped slider 303, the cross connecting rod 305 and the abutting block 306 will be pushed back to their original positions to wait for the next operation.

[0064] The implementation principle of the municipal road drainage pipe installation device in the embodiment of the present application is as follows: First, the pipeline 106 is lifted by a crane above the inclined guide rod 105, and then slowly lowered to the bottom of the inner cavity of the vehicle frame 100 through the inclined guide rod 105. At the same time, one end of the pipeline 106 that needs to be coated with lubricant abuts against the arc surface of the scraping knife 207, and the other end of the pipeline 106 abuts against the arc surface of the arc-shaped receiving groove 304 provided on one side of the special-shaped slider 303. After the pipeline 106 is placed stably, the lifting rope is removed, and then the control switch of the motor 103 is turned on to make the motor 103 operate. Then, the output end of the motor 103 drives the reciprocating lead screw 104 to rotate, thereby driving the first straight gear 201 to rotate. While the first straight gear 201 rotates, it drives the second straight gear 202 to rotate synchronously. Then, the second straight gear 202 drives the transmission assembly 203 rotatably arranged on the cross bar of the L-shaped fixing plate 210 to rotate, and then transmits the power to the grinding wheel 204 fixedly arranged on one side of the transmission assembly 203. Since the grinding wheel 204 abuts against the outer ring surface of the pipeline 106, when the grinding wheel 204 rotates, the friction with the outer ring surface of the pipeline 106 is increased through the rubber strip provided on its outer ring surface, thereby driving the pipeline 106 to rotate.

[0065] While the grinding wheel 204 drives the pipeline 106 to rotate, the grinding wheel 204 also drives the roller 205 to rotate on the storage bin 206. Then, while the roller 205 rotates, it adsorbs the lubricant in the storage bin 206 and applies it to the outer ring surface of the pipeline 106. Before applying the lubricant, the outer ring surface of the pipeline 106 is processed by the scraper 207 and the cleaning strip 208 arranged at the lower end of the roller 205. Among them, the scraper 207 is responsible for scraping the dust on the pipeline 106, and the cleaning strip 208 is responsible for wiping and cleaning the surface of the pipeline 106 after scraping, further cleaning the ring surface at the butt joint of the pipeline 106, and then applying the lubricant.

[0066] Meanwhile, while the reciprocating lead screw 104 rotates, it also drives the special-shaped scraper 301 threadedly connected thereto to move reciprocally. When the special-shaped scraper 301 moves towards the abutting block 306, the inclined surface scraper 302 provided on the special-shaped scraper 301 will scoop up the soil on both sides of the pipeline 106 and fill the bottom of the pipeline 106 to achieve the effect of supporting and fixing. When the special-shaped scraper 301 abuts against the abutting block 306 during the moving process, the special-shaped scraper 301 will push the abutting block 306 to move synchronously, and then the abutting block 306 drives the cross link 305 to move synchronously. During the moving process of the cross link 305, it will drive the special-shaped slider 303 to move together, and drive the pipeline 106 to move synchronously through the arc-shaped receiving groove 304, so that the pipeline 106 can be docked and sealed and fixed with the previously installed pipeline 106. When the special-shaped scraper 301 moves in the opposite direction, under the action of the compression spring 307, the special-shaped slider 303, the cross link 305 and the abutting block 306 will be pushed back to their original positions, thus realizing the reset and waiting for the next operation.

[0067] Embodiment 2

[0068] Refer to Figures 1-8 , an installation method, applied to the above-mentioned municipal road drainage pipe installation device, including the following steps:

[0069] S01. At the beginning of the installation operation, use a crane to hoist the pipeline 106 to be installed directly above the inclined guide rod 105. Then, along the guidance of the inclined guide rod 105, slowly and steadily lower the pipeline 106 to the bottom of the inner cavity of the vehicle frame 100. During this process, the end of the pipeline 106 that needs to be coated with lubricant is in close contact with the arc surface of the scraper 207, and the other end of the pipeline 106 is accurately in contact with the arc surface of the arc-shaped receiving groove 304 arranged on one side of the special-shaped slider 303. After the pipeline 106 is stably placed at the bottom of the inner cavity of the vehicle frame 100, carefully remove the lifting rope to complete the hoisting and preliminary positioning work of the pipeline.

[0070] S02. After the positioning of the pipeline 106 is completed, the control switch of the motor 103 is turned on, and the motor 103 starts to operate. The output end of the motor 103 drives the reciprocating lead screw 104 to rotate. The rotation of the reciprocating lead screw 104 drives the first straight gear 201 to rotate synchronously. Since the first straight gear 201 meshes with the second straight gear 202, the rotation of the first straight gear 201 will drive the second straight gear 202 to rotate synchronously. The second straight gear 202 drives the transmission component 203 rotatably arranged on the cross bar of the L-shaped fixing plate 210 to rotate. The transmission component 203 transmits power to the grinding wheel 204 fixedly arranged on one side thereof. Since the grinding wheel 204 is in close contact with the outer ring surface of the pipeline 106 and there is an adhesive strip on the outer ring surface of the grinding wheel 204, the friction with the outer ring surface of the pipeline 106 is increased. Therefore, when the grinding wheel 204 rotates, it can drive the pipeline 106 to rotate.

[0071] While the pipeline 106 is rotating, the grinding wheel 204 will also drive the roller 205 to rotate on the storage bin 206. Before applying the lubricant, the scraper 207 and the cleaning strip 208 arranged at the lower end of the roller 205 will first process the outer ring surface of the pipeline 106. The scraper 207 is responsible for scraping off the dust on the pipeline 106, and the cleaning strip 208 wipes and cleans the surface after scraping, ensuring that the ring surface at the docking port of the pipeline 106 is relatively clean and dust-free, and making preparations for the subsequent application of the lubricant.

[0072] S03. As the roller 205 rotates, it will adsorb the lubricant in the storage bin 206 and evenly apply it to the outer ring surface of the pipeline 106 to ensure the lubricity during the docking of the pipeline 106. At the same time, the rotation of the reciprocating lead screw 104 will also drive the special-shaped scraper 301 threadedly connected thereto to move reciprocally. When the special-shaped scraper 301 moves towards the abutting block 306, the inclined surface scraper 302 provided on the special-shaped scraper 301 will scoop up the soil on both sides of the pipeline 106 and fill the bottom and both sides of the pipeline 106, thus playing a role in supporting and fixing. When the special-shaped scraper 301 abuts against the abutting block 306 during the movement, it will push the abutting block 306 to move synchronously. The abutting block 306 drives the cross link 305 to move synchronously. During the movement of the cross link 305, it will drive the special-shaped slider 303 to move together. The special-shaped slider 303 drives the pipeline 106 to move synchronously through the arc-shaped receiving groove 304, enabling the pipeline 106 to be docked with the previously installed pipeline 106 and achieving sealing and fixing.

[0073] S04. When the special-shaped scraper 301 moves in the opposite direction, under the action of the compression spring 307, the special-shaped slider 303, the cross link 305 and the abutting block 306 will be pushed back to their original positions to achieve reset and wait for the next operation. Through the coordinated work of the above parts, the device can efficiently and accurately complete the installation task of the municipal road drainage pipe.

[0074] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.

Use a crane to lift the pipe (106) above the inclined guide rod (105), and then slowly place it along the inclined guide rod (105) to the bottom of the inner cavity of the frame (100). At this time, one end of the pipe (106) to be coated with lubricant abuts against the arc surface of the scraper (207), and the other end abuts against the arc surface of the arc-shaped receiving groove (304) on one side of the special-shaped slider (303). After the pipe (106) is placed stably, remove the lifting rope; S02. Subsequently, the motor (103) control switch is turned on, and the motor (103) drives the reciprocating screw (104) fixed to the output end to rotate, and the rotation of the reciprocating screw (104) drives the first spur gear (201) to rotate, and the first spur gear (201) is engaged with the second spur gear (202), so that the second spur gear (202) rotates synchronously, and the second spur gear (202) drives the transmission assembly (203) set on the crossbar of the L-shaped fixed plate (210) to rotate, and transmits power to the grinding wheel (204) fixed on one side of the transmission assembly (203). Since the grinding wheel (204) is in contact with the outer annular surface of the pipe (106), and the outer annular surface is provided with a rubber strip to increase friction, the pipe (106) is driven to rotate; S03. While the grinding wheel (204) drives the pipeline (106) to rotate, the grinding wheel (204) drives the roller (205) to rotate on the storage bin (206). The roller (205) rotates to adsorb the lubricant in the storage bin (206), and applies it to the outer ring surface of the pipeline (106). Before applying the lubricant, the scraper (207) and the cleaning strip (208) provided at the lower end of the roller (205) first process the outer ring surface of the pipeline (106).
