Description

Technical Field

[0001] The invention relates to the technical field of pipeline laying, and in particular to a municipal construction drainage pipe laying device. Background Art

[0002] Drain pipe laying is a vital link in municipal engineering, involving the normal operation and maintenance of residential, commercial and industrial facilities. The main function of the drainage pipe system is to collect and guide wastewater and rainwater inside and outside the building, prevent water accumulation, protect the structure of the building, avoid water pollution, and improve the sanitary conditions of the living and working environment. An effective drainage system helps prevent fires, avoid foundation erosion, and reduce the impact on the environment. During the drainage pipe laying process, the drainage pipe system is usually large in scope, and most of the drainage pipes are laid in a straight line. Straight laying can effectively reduce water flow resistance and improve the efficiency of the drainage system. When two adjacent drainage pipes are connected in a straight line, the sealing is better.

[0003] In the existing municipal construction drainage pipe laying, the cooperation of cranes and manual labor is usually adopted to realize the connection and installation of two drainage pipes, but the following problems still exist. In the process of laying the drainage pipe, the drainage pipe is usually hoisted into the pit by a crane and a lifting rope, and then the drainage pipe is aligned with the previous section of the drainage pipe through manual adjustment, and then the sealing ring is cleaned and installed, and the drainage pipe is pushed into the pipe mouth of the previous section of the drainage pipe to complete the installation. However, manual adjustment usually has errors, and it cannot be guaranteed that the installation of each section of the pipeline is completely straight. The non-straight state will affect the sealing of the sealing area and increase the resistance of sewage during subsequent drainage.

At this time, the installer directly pushes the pipe to be installed into the inside of the previous section of the pipe, and the positioning installation can be quickly completed, ensuring that the two adjacent pipes are laid in a straight line, and there is no need to manually adjust the position of the pipe throughout the process, thereby improving the laying efficiency and ensuring the laying quality.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a municipal construction drainage pipe laying device, including a pipe 1 and a positioning box 2, and also includes a positioning unit installed on the positioning box 2, the positioning unit includes a positioning component installed inside the positioning box 2 and a fixing component installed on the side wall of the positioning box 2;

[0038] The positioning components include a linkage box 3 fixedly mounted on the upper end of the positioning box 2, a balance box 4 fixedly mounted on the lower side of one end of the linkage box 3 away from the positioning box 2, a close-fitting block 5 fixedly mounted on the lower ends of the positioning box 2 and the balance box 4, respectively, two mounting plates 6 fixedly mounted on the inner side walls of the balance box 4 and the positioning box 2, respectively, a driving screw 7 rotatably mounted between the two corresponding mounting plates 6, a nut block 8 threadedly mounted on both ends of the driving screw 7, a limiting groove 9 provided at the lower ends of the positioning box 2 and the balance box 4, a clamping rod 10 fixedly mounted on the lower end of the nut block 8, a square plate 11 fixedly mounted on the side wall of the lower end of the clamping rod 10, and a clamping plate 12 fixedly mounted on the square plate 11;

[0039] The close-fitting block 5 is located at the center of the positioning box 2. The close-fitting block 5 and the clamping plate 12 are both arc-shaped, and the curvature of both is equal to the curvature of the outer wall of the pipe 1. Thread grooves are provided at both ends of the two driving screws 7, and the thread directions of the two thread grooves on the same driving screw 7 are opposite. Multiple nut blocks 8 are threadedly installed on the corresponding driving screws 7 through the thread grooves. The clamping rod 10 passes through the corresponding limiting grooves 9 and the lower ends are located on both sides of the pipe 1. A driving assembly is installed inside the linkage box 3, and a transmission assembly is installed between the two driving screws 7 and the linkage box 3.

[0040] Reference Figure 4-Figure 7The driving assembly includes a driving motor 13 fixedly mounted on the outer wall of the upper end of the linkage box 3, a driving rod 14 fixedly mounted on the driving end of the driving motor 13, a transmission wheel 15 fixedly mounted on the driving rod 14, a transmission rod 16 that is sealed and rotated and penetrates the upper wall of the balance box 4, a transmission wheel 2 17 fixedly mounted on the upper end of the transmission rod 16, and a transmission belt 18 sleeved between the transmission wheel 15 and the transmission wheel 2 17. The transmission assembly includes a bevel gear 19 fixedly mounted on the lower ends of the driving rod 14 and the transmission rod 16, and a bevel gear 20 fixedly mounted on the outer wall of the middle ends of the two driving screws 17, and the two bevel gears 19 are meshed with the corresponding bevel gear 20.

[0041] Specifically, the positioning component is used to position the pipe 1 installed in the previous section, find the center of the pipe 1 installed in the previous section, and facilitate the installer to directly align the subsequent pipe 1 to be installed with the previous section of the pipe 1 through the positioning component, so as to achieve the effect of rapid positioning and installation, and effectively improve the laying efficiency and quality. Because in the process of laying the pipe 1, the pipe 1 with a fixed diameter is usually used for laying, so by setting a close block 5 with the same curvature as the outer wall of the pipe 1, when the close block 5 is close to the outer wall of the pipe 1, the center of the arc of the close block 5 coincides with the arc of the pipe 1, and the center of the pipe 1 can be quickly found at this time. When the centers of the two pipes 1 are at the same horizontal height, the two pipes 1 are also in the same straight line in the vertical direction. At this time, the installer can quickly install the pipe 1 at the pipe mouth of the previous section of the pipe 1, and can ensure that the two pipes 1 are connected in a straight line. The straight line connection can effectively reduce the resistance of the water flow in the pipe 1 and improve the drainage efficiency. At the same time, the straight line installation can better improve the sealing of the sealing ring and improve the stability of the drainage system.

[0042] The clamping rod 10 and the clamping plate 12 are used to firmly fix the positioning box 2 and the balance box 4 on the pipe 1 installed in the previous section, which is convenient for the subsequent use of the fixing components, and the distances between the multiple clamping plates 12 and the corresponding close-fitting blocks 5 are the same, so that when the multiple clamping plates 12 are under the action of the driving assembly, the multiple clamping plates 12 move synchronously and uniformly toward the middle, and the multiple clamping plates 12 can contact the outer wall of the pipe 1 at the same time, ensuring that the close-fitting block 5 is close to the outer wall of the pipe 1, and then ensuring that the center of the close-fitting block 5 coincides with the center of the pipe 1. The function of the balance box 4 is to improve the stability of the positioning component, so that the positioning box 2 is more firmly fixed on the outer wall of the pipe 1, which is conducive to improving the stability and firmness of the fixing component when it is used.

[0043] During use, the installer first installs the first section of the pipe 1 at the outlet of the drainage pipe, then places the positioning box 2 and the balancing box 4 close to the outer wall of the first section of the installed pipe 1, and turns on the driving motor 13. The driving motor 13 drives the driving rod 14 to rotate through the driving end. The rotation of the driving rod 14 drives the transmission rod 16 to rotate synchronously through the transmission belt 18. The rotation of the driving rod 14 and the transmission rod 16 drives the corresponding bevel gear 19 to rotate, and then drives the corresponding bevel gear 20 to rotate. When the bevel gear 20 rotates, it will drive the corresponding driving screw 7 to rotate synchronously. When the two driving screws 7 rotate, the limiting groove 9 limits the corresponding nut block 8 through the clamping rod 10, so that the nut block 8 will not rotate synchronously. Then, when the driving screw 7 rotates, it will drive the nut blocks 8 at both ends to move synchronously toward the middle end. When the two nut blocks 8 move, the clamping plate 12 is driven to move synchronously through the clamping rod 10 until the clamping plate 12 is tightly clamped on the outer wall of the pipe 1, completing the positioning and fixing of the positioning box 2.

[0044] Example 2, reference Figure 8-Figure 11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the fixing component includes a receiving plate 21 fixedly mounted on the outer wall of the positioning box 2, a guide plate 22 fixedly mounted on the receiving plate 21, two branch plates 23 fixedly mounted on the guide plate 22, two support plates 24 respectively fixedly mounted on the inner walls of the two branch plates 23, a driving screw rod 25 rotatably mounted on the corresponding two support plates 24, and nut blocks 26 respectively threadedly mounted on the two ends of the corresponding driving screw rod 25, both ends of the two driving screw rods 25 are provided with spiral grooves, and the spiral directions of the two corresponding spiral grooves are opposite, the receiving plate 21 is located at the center of the positioning box 2, the receiving plate 21 is installed on the outer wall of the positioning box 2 by disassembling the assembly, the lower end of each nut block 26 is installed with a limiting assembly, and a synchronization assembly is installed between the two driving screw rods 25.

[0045] The limiting assembly includes limiting rods 30 respectively fixedly mounted on the lower ends of multiple nut blocks 26, and limiting plates 31 fixedly mounted on the side walls of the lower ends of the limiting rods 30. The multiple limiting plates 31 are all arc-shaped, and the curvature is equal to the curvature of the outer wall of the pipeline 1.

[0046] The synchronization component includes a second drive motor 32 fixedly mounted on one side of the branch plate 23, a synchronization wheel 33 respectively fixedly mounted on two second drive screws 25, a second transmission belt 34 sleeved between the two synchronization wheels 33, and a protection box 35 fixedly mounted between the two branch plates 23. The second transmission belt 34 is located in the protection box 35. The driving end of the second drive motor 32 is fixedly connected to one end of the corresponding second drive screw 25. Multiple installation grooves are provided on the arc surface of multiple limit plates 31, and a ball 36 is slidably installed inside each installation groove. The center of the circle of the close-fitting block 5 and the center of the circle of the limit plate 31 are on the same height level.

[0047] Specifically, the function of the fixing component is to fix and limit the pipe 1 to be installed. The limited pipe 1 is directly aligned with the previous pipe 1 due to the positioning component, and the two pipes 1 are in a straight line state. It has the advantage of not requiring manual position adjustment and directly ensuring that the limited pipe 1 is in a straight line with the previous pipe 1, thereby effectively improving the efficiency and quality of laying the pipe 1. In particular, when the two corresponding nut blocks 26 are in the closest state, the limiting plates 31 corresponding to the lower ends of the two nut blocks 26 are tightly attached to the outer wall of the pipe 1. Because the curvature of the limiting plates 31 is the same as the curvature of the outer wall of the pipe 1, the center of the pipe 1 located in the two corresponding limiting plates 31 is at the same height and on the same horizontal line as the center of the previous section of the pipe 1, and the guide plate 22 is a straight line. This makes it possible for the pipe 1 to be installed to be parallel to the guide plate 22 when it is fixed on the corresponding limiting plate 31, and the guide plate 22 is also parallel to the previous section of the pipe 1, so that the pipe 1 to be installed is parallel to the previous section of the pipe 1, and because the center of the circle is at the same height, the pipe 1 to be installed fixed by the fixing component is aligned with the previous section of the pipe 1 and in a straight line.

[0048] A plurality of balls 36 are arranged on the surface of the limit plate 31. The function of the balls 36 is as follows: when the limit plate 31 limits the pipe 1 to be installed, the balls 36 can make the pipe 1 slide inside the limit plate 31, so that the installer can push the pipe 1 to be installed between the two limit plates 31, and after aligning and installing the sealing ring, the installer can push the pipe 1 to be installed into the pipe mouth of the previous pipe 1 to complete the connection installation of the two pipes 1.

[0049] During use, after the positioning box 2 and the balancing box 4 are fixed on the outer wall of the upper section of the pipeline 1, the driving motor 2 32 is turned on, so that the driving motor 2 32 drives the corresponding driving screw 25 to rotate through the driving end, and at the same time drives the other driving screw 25 to rotate synchronously through the synchronous wheel 33 and the transmission belt 2 34. When the two driving screws 25 rotate, the nut blocks 26 at both ends are driven to approach each other to the closest distance. At this time, the corresponding two limit plates 31 are at a relatively closest distance (when the two limit plates 31 are at the closest distance, the two limit plates 31 are just at a distance close to the outer wall of the pipeline 1). At this time, the installer will install the pipeline to be installed 1 penetrates from the end to the corresponding two limiting plates 31. At this time, multiple limiting plates 31 limit the pipe 1 to be installed to prevent the pipe 1 to be installed from tilting relative to the previous pipe 1. Then, the pipe openings of the two pipes 1 that are close to each other are cleaned and a sealing ring is installed. After the installation is completed, the installer pushes from the end of the pipe 1 to be installed toward the direction of the first pipe 1, inserts the pipe opening of the pipe 1 to be installed into the inside of the previous pipe 1, and completes the connection installation. After the installation is completed, the drive motor 2 32 and the drive motor 1 13 are rotated in the opposite direction to make the multiple limiting plates 31 and the clamping plate 12 move outward, release the fixation and limiting of the pipe 1, and take out the device.

[0050] The remaining structures are the same as those of Example 1.

[0051] Example 3, reference Figure 1 and Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the disassembly component includes threaded holes 27 opened on the receiving plate 21 and the side wall of the positioning box 2, threaded rods 28 threadedly installed on the two corresponding threaded holes 27, and pentagonal nuts 29 threadedly installed on the corresponding threaded rods 28.

[0052] Specifically, the disassembly assembly enables the fixing component to be removed from the positioning component, making it easier for installers to carry and move the device, and can effectively reduce the footprint of the device during storage, making it easier to store, effectively improving the applicability of the device, and reducing the difficulty of the installers during their work.

[0053] The remaining structure is the same as that of Example 2.

[0054] In summary, the working principle of the present invention is as follows: the installer first installs the first section of the pipe 1 at the outlet of the drainage pipe, then places the positioning box 2 and the balance box 4 close to the outer wall of the first section of the installed pipe 1, and turns on the drive motor 13. The drive motor 13 drives the drive rod 14 to rotate through the drive end. The drive rod 14 rotates through the transmission belt 18 to drive the transmission rod 16 to rotate synchronously. The rotation of the drive rod 14 and the transmission rod 16 drives the corresponding bevel gear 19 to rotate, and then drives the corresponding bevel gear 20 to rotate. When the bevel gear 20 rotates, it will drive the corresponding driving screw 17 to rotate synchronously. When the two driving screws 7 rotate, the limiting groove 9 limits the corresponding nut block 8 through the clamping rod 10, so that the nut block 8 will not rotate synchronously. Then, when the driving screw 7 rotates, the nut blocks 8 at both ends will be driven to move synchronously toward the middle end. When the two nut blocks 8 move, the clamping plate 12 is driven to move synchronously through the clamping rod 10 until the clamping plate 12 is tightly clamped on the outer wall of the pipe 1, thereby completing the positioning and fixation of the positioning box 2.

[0055] After the positioning box 2 and the balancing box 4 are fixed on the outer wall of the previous section of the pipeline 1, the driving motor 2 32 is turned on, so that the driving motor 2 32 drives the corresponding driving screw 25 to rotate through the driving end, and at the same time drives the other driving screw 25 to rotate synchronously through the synchronous wheel 33 and the transmission belt 2 34. When the two driving screws 25 rotate, the nut blocks 26 at both ends are driven to approach each other to the closest distance. At this time, the corresponding two limit plates 31 are at a relatively closest distance (when the two limit plates 31 are at the closest distance, the two limit plates 31 are just at a distance close to the outer wall of the pipeline 1). At this time, the installer inserts the pipeline 1 to be installed from the end into the corresponding two limit plates 31. At this time, multiple limit plates 31 limit the pipeline 1 to be installed to prevent the pipeline 1 to be installed from tilting relative to the previous section of the pipeline 1.

[0056] Then the installer cleans the adjacent pipe openings of the two pipes 1 and installs sealing rings. After the installation is completed, the installer pushes from the end of the pipe 1 to be installed in the direction of the first section of the pipe 1, and inserts the pipe opening of the pipe 1 to be installed into the interior of the previous section of the pipe 1 to complete the connecting installation. After the installation is completed, the drive motor 2 32 and the drive motor 1 13 are rotated in reverse to make the multiple limit plates 31 and the clamping plate 12 move outward, release the fixation and limit of the pipe 1, and take out the device.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
