Description

Technical Field

[0001] The utility model relates to the field of rainwater and sewage pipe networks, and in particular to a pipe burying device for rainwater and sewage pipe network reconstruction. Background Art

[0002] The rainwater and sewage pipe network is a type of urban infrastructure project, including the rainwater pipe network and the sewage pipe network, which are used to collect and discharge rainwater and wastewater in the city. The rainwater pipe network refers to the drainage system used to collect and transport rainfall in the city. It is composed of drainage pipes, manhole covers, rainwater inlets, inspection wells, etc. It is mainly used to avoid waterlogging and flood disasters in the city. During the renovation of the rainwater and sewage pipe network, a pipe laying device is needed to lift the pipes, so as to facilitate the underground laying of rainwater and sewage pipes. The pipe laying device is to bury the pipes in the concrete in a fixed position in advance, so that the pipe layout is more standardized and beautiful.

[0003] After searching, a pipe burying device for urban rainwater and sewage pipe network renovation with publication number CN217539850U is found, which specifically discloses a pipe burying device for urban rainwater and sewage pipe network renovation. The utility model includes a bracket, bottom plates are fixed to the bottom surfaces of both sides of the outside of the bracket, universal wheels are fixed to both sides of the outside bottom surface of the bottom plate, a pipe ring is arranged inside the bracket, a cushion block is fixed to the top surface of the outside of the bracket, a motor is arranged on the top surface of the outside of the cushion block, a wheel frame is fixed to the top surface of the outside of the bracket, and a rotating wheel is arranged inside the wheel frame. The device is used through a mobile device, so that it can be more convenient and quick to move and transport the pipes. At the same time, the arrangement of the pipe ring, the lifting rope, the rotating wheel and the motor can reduce the labor workload of the staff and improve the efficiency of pipe installation and laying, which greatly improves the practicability of the device.

[0004] During use, the existing pipeline burying device only lifts the pipeline by a steel cable, and then buries the pipeline underground by lowering the steel cable. This pipeline burying method is not stable enough and requires multiple workers or multiple pipeline burying devices to cooperate with each other to complete the pipeline burying work. In addition, the above-mentioned comparative cases also lack other means to stabilize the lifting, lowering and balancing of the rainwater and sewage pipes. This not only increases the overall cost of burying the rainwater and sewage pipes during long-term use, but also wastes time and effort to delay the renovation of the rainwater and sewage pipe network.

[0005] Therefore, it is necessary to invent a pipeline burying device for rainwater and sewage pipe network reconstruction to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a pipe burying device for the reconstruction of rainwater and sewage pipe networks. Through the cross frame plate, hydraulic cylinder, hydraulic rod, retractable frame, servo motor, steel cable drum and connecting steel cable, the tedious operation of the pipe burying work that requires multiple workers or multiple pipe burying devices to cooperate with each other is avoided. The hydraulic cylinder and servo motor are automatically lifted and lowered throughout the whole process, which saves the labor of workers. Moreover, the two-stage lifting also provides a certain safety guarantee for the rainwater and sewage pipe burying work, reduces the overall rainwater and sewage pipe burying cost, and speeds up the timeliness of the rainwater and sewage pipe network reconstruction work, so as to solve the problem that in the prior art, the pipe burying device only lifts the pipe by the steel cable during use, and then buries the pipe underground by descending the steel cable. Such a pipe burying method is not stable enough, and requires multiple workers or multiple pipe burying devices to cooperate with each other to complete the pipe burying work. In addition, the above-mentioned comparative case also lacks other means for stabilizing the lifting, lowering and balancing of the rainwater and sewage pipes. In this way, in the long-term use process, not only the overall rainwater and sewage pipe burying cost is increased, but also the time-consuming and labor-intensive rainwater and sewage pipe network reconstruction work is delayed.

The fixed frame can be driven by the hydraulic cylinder and the hydraulic rod to be balanced and lowered, so that the rainwater and sewage pipes can be completely fitted to the ground to be buried, which is convenient for workers to remove the connecting cable to complete the pipe burying work. Such a two-stage lifting and burying operation of the pipe avoids the cumbersome operation that requires multiple workers or multiple pipe burying devices to cooperate with each other to complete the pipe burying work. The hydraulic cylinder and the servo motor are automatically lifted and lowered throughout the whole process, which saves the labor of the workers, and the two-stage lifting also provides a certain safety guarantee for the burying of the rainwater and sewage pipes, reduces the overall burying cost of the rainwater and sewage pipes, and speeds up the time efficiency of the rainwater and sewage pipe network transformation work;

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The pipe embedding device for rainwater and sewage pipe network reconstruction shown includes a frame 1 for supporting the weight of the pipe;

[0029] The inner slide groove 6 is arranged inside the frame 1 and is used for connecting and installing the inner slide block 7, and a cross frame plate 8 is fixedly installed at one end of the inner slide block 7, a hydraulic cylinder 9 is arranged at the bottom of the cross frame plate 8, and a hydraulic rod 10 is movably connected inside the hydraulic cylinder 9;

[0030] A lifting rod 11 is arranged above the horizontal frame plate 8 and is used to drive the pipeline to perform preliminary lifting and lowering. A fixing frame 12 is fixedly installed at one end of the lifting rod 11. An inner through groove 13 is provided inside the fixing frame 12. An outer movable sleeve 14 is movably connected to the outside of the fixing frame 12. A positioning screw 15 is passed through one side of the outer movable sleeve 14.

[0031] The retractable frame 16 is arranged above the fixed frame 12, and is used for secondary adjustment of the height distance of the pipeline. A servo motor 17 is arranged on the outside of the retractable frame 16, and the output end of the servo motor 17 is fixedly connected to a connecting rod 18, and a steel cable drum 19 is fixedly installed on the outside of the connecting rod 18, and a connecting steel cable 20 is fixedly connected to the outside of the steel cable drum 19. The steel cable descends under the drive of the servo motor 17, and there is no need to loosen the steel cable to let the pipeline escape from the pipeline burying device. In this way, one end of the pipeline will be heavy and the other end will be light during the loosening process, thereby causing installation hazards. The fixed frame 12 can be driven by the hydraulic cylinder 9 and the hydraulic rod 10 to perform a secondary balanced descent so that the rainwater and sewage pipes can be completely fitted to the ground to be buried, making it convenient for workers to remove the connecting steel cable 20 to complete the pipeline burying work.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a roller 2 is provided on the outside of the frame 1, a resistance shaft 3 is provided on one side of the frame 1, a fixing rod 4 is fixedly installed on the outside of the resistance shaft 3, and a screw positioning cone 5 is penetrated on the top of the fixing rod 4. The roller 2 on the outside of the frame 1 can be used to directly push the device to the pipeline burying site where a pit has been dug. The cross frame plate 8 is slidably connected to the frame 1, and the hydraulic cylinder 9 and the hydraulic rod 10 are vertically distributed. The power of the hydraulic cylinder 9 and the hydraulic rod 10 is sufficient to support the lifting pressure of the rainwater and sewage pipes.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the outer movable sleeve 14 is movably connected to the fixing frame 12, and the positioning screw 15 is symmetrically arranged with the central axis of the outer movable sleeve 14. The center of gravity is adjusted by the outer movable sleeve 14, so that the rainwater and sewage pipes can be stably lifted by the pipe burying device under the lifting of three sets of connecting steel cables 20. A first pipe clamp 21 is fixedly installed at one end of the connecting steel cable 20, and a fixing bolt 22 passes through the outside of the first pipe clamp 21. One end of the fixing bolt 22 is movably connected with a second pipe clamp 23. The first pipe clamp 21, the fixing bolt 22 and the second pipe clamp 23 have a simple structure. The matching first pipe clamp 21 and the second pipe clamp 23 can be selected according to rainwater and sewage pipes of different sizes to facilitate pipeline burying. The second pipe clamp 23 is threadedly connected to the first pipe clamp 21, and the fixing bolt 22 is symmetrically arranged with the central axis of the second pipe clamp 23. The cost of the first pipe clamp 21 is low, and it is convenient for the operator to replace it in time if a fault occurs, without delaying the normal use of the device.

[0034] The practical working principle of the present invention is as follows: first, the device is pushed to the location where the rainwater and sewage pipes are placed, and then the external power supply is turned on. The matching first pipe clamp 21 and second pipe clamp 23 are selected through rainwater and sewage pipes of different sizes to facilitate the burying of the pipes. Then, the first pipe clamp 21 and the second pipe clamp 23 are sleeved on the outside of the rainwater and sewage pipes through the fixing bolts 22, and the center of gravity is adjusted through the external movable sleeve 14. Then, the positioning screw 15 is tightened to fix the position of the current three sets of connecting cables 20. After the preparation work is completed, the switch of the servo motor 17 can be started, and the servo motor 17 drives the cable drum 19 to rotate, thereby driving the connecting cable 20 to reel in. As the connecting cable 20 is reeled in, the rainwater and sewage pipes are lifted a certain distance, and then the device can be directly pushed to the pipe burying location where the pit has been dug, and then the same operation is used to relax the connecting cable 20 to lower the rainwater and sewage pipes into the dug pit. Subsequently, there is no need to loosen the cable to let the pipes leave the pipe burying device. This In this way, one end of the pipeline will be heavy and the other end will be light during the loosening process, thus causing installation hazards. The switch of the hydraulic cylinder 9 can be turned on, and the lifting of the hydraulic cylinder 9 and the hydraulic rod 10 can drive the fixed frame 12 to lift up and down above the frame 1. The fixed frames 12 at both ends are lowered synchronously to allow the rainwater and sewage pipes to be balanced and lowered, so that they are completely fitted to the ground to be buried, making it convenient for workers to take off the connecting steel cable 20 and the first pipe clamp 21 and the second pipe clamp 23 to complete the pipeline burying work. Such a two-level lifting and burying pipeline operation avoids the cumbersome operation that requires multiple workers or multiple pipeline burying devices to cooperate with each other to complete the pipeline burying work. The hydraulic cylinder 9 and the servo motor 17 are automatically lifted and lowered throughout the process, saving the labor of the workers. Finally, after completing the installation and use of all the pipeline burying devices according to the above operations, turn off the switch of the hydraulic cylinder 9, turn off the switch of the servo motor 17, and cut off the external power supply if it is not used for a long time. In this way, the use process of the pipeline burying device for the transformation of the rainwater and sewage pipeline network is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
