Description

Technical Field

[0001] This invention relates to the field of sewage pipeline technology, specifically to a support device for connecting and installing municipal sewage pipelines. Background Technology

[0002] Sewage pipelines consist of pipes and their ancillary structures that collect and transport urban sewage. Sewage flows from branch pipes into main pipes, then into the main trunk, and finally into sewage treatment plants. The pipelines are distributed in a tree-like pattern, from small to large, which is completely different from the circulation of water supply networks. Sewage generally flows from high to low in the pipelines due to the difference in water levels at both ends. The pipelines do not bear pressure and flow by gravity.

[0003] Support devices for municipal sewage pipeline connection and installation are auxiliary equipment used in pipeline construction. They help construction workers to complete the connection and installation of pipelines efficiently and accurately. The support device usually consists of a fixed plate, support rod, mounting frame, etc. It can provide support for pipeline installation and connection, and the support height can be adjusted according to actual needs to adapt to the installation of pipelines with different diameters and lengths.

[0004] The replacement steps for damaged socket-type cement pipes in the existing technology are as follows: dig the pipe area with excavation equipment, then remove the damaged pipe. When the damaged pipe is close to the inspection well, the inspection well and the pipe in between need to be removed together. After the damaged pipe is replaced and the remaining pipes are reinstalled, the inspection well is rebuilt.

[0005] When the damaged pipe is not near the inspection well, the damaged pipe must be removed. This application is for the replacement of socket-type cement pipes. The connection method of socket-type cement pipes is sequential plugging. After the pipe is removed, the installation length space will be less than the length of the socket-type cement pipe, making it impossible to directly install and connect the pipe.

[0006] Because socket-type cement pipes have plug-in connections at both ends, existing technologies cannot directly install new socket-type cement pipes of the original length after removing damaged ones due to installation size limitations. Instead, smaller-length socket-type cement pipes are installed after removal, leaving gaps. Existing technologies involve building inspection wells in these gaps and conducting periodic inspections of these wells. This increases the amount of building materials needed for repairing socket-type cement pipes and wastes manpower on subsequent inspections of the inspection wells. Summary of the Invention

[0007] To address the aforementioned problems, this invention proposes a support device for connecting and installing municipal sewage pipelines.

[0008] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0009] A support device for connecting and installing municipal sewage pipes includes several adjustable support mechanisms that allow socket-type cement pipes to be tilted and connected. Each adjustable support mechanism includes a main support frame, on which a hoisting mechanism is provided. The hoisting mechanism is connected at its end to an angle adjustment mechanism located inside the main support frame. The socket-type cement pipe is located on the angle adjustment mechanism, and the angle adjustment mechanism can adjust the inclination angle of the socket-type cement pipe. The angle adjustment mechanism is provided with a fixing mechanism that can fix the socket-type cement pipe.

[0010] The main support frame includes a top plate, the hoisting mechanism is fixed to the top plate, and several vertical piles are slidably inserted through the top plate. The vertical piles are inserted vertically into the ground. The angle adjustment mechanism includes a base plate, and the base plate has an end block that is slidably connected to the vertical pile. A hinge plate is hinged to one end of the base plate, and the hinge plate has several mounting holes. Two pipe pads are provided on the hinge plate, and a socket-type cement pipe is located on the pipe pad. A threaded rod is provided on the base plate, and a screw block is threadedly connected to the threaded rod. Both ends of the screw block have connectors. Two support rods are hinged to the bottom of the hinge plate, and the ends of the support rods have grooves. The connectors are located in the grooves and are slidably connected to the grooves.

[0011] As an improvement, the base plate is provided with two grooves on both sides of the lead screw, and a limiting plate is slidably provided in the groove. The bottom of the hinge plate is hinged with limiting rods on both sides of the two support rods. The two limiting rods are respectively engaged with the two limiting plates. The end of the limiting plate is provided with a connecting plate that passes through the base plate. The connecting plate is provided with a handle to facilitate the disengagement of the limiting plate from the limiting rods.

[0012] As an improvement, the top plate is provided with several electric telescopic rods 1 on both sides, which can increase the span of the adjustable support mechanism. Each of the electric telescopic rods 1 is provided with an electric telescopic rod 2 at its end. The bottom of the electric telescopic rod 2 is provided with a support seat, and the support seat is provided with retractable casters.

[0013] As an improvement, the hoisting mechanism includes a double rope roller, a driving device is provided on one side of the double rope roller, and two hoisting ropes with the same winding direction but opposite output directions are provided on the outside of the double rope roller. Two correction frames are provided on the top plate, and an auxiliary wheel is provided on one side of the correction frame. The hoisting rope passes through the correction frame and the auxiliary wheel and extends downward, and a connecting hook connected to the bottom plate is provided at the bottom end.

[0014] As an improvement, the pipe gasket is fixedly connected to the hinge plate by bolts passing through the mounting holes. The pipe gasket is provided with several rotating wheels, which are in rolling connection with the socket-type cement pipe.

[0015] As an improvement, the fixing mechanism includes a rope locking device located above the socket-type cement pipe, with locking ropes at both ends located outside the socket-type cement pipe. The locking ropes pass through the mounting holes, and each end of the two locking ropes is provided with a connecting hook, which is connected to each other.

[0016] As an improvement, the base plate is provided with a pad, the hinge plate is in a horizontal state when in contact with the pad, and the end of the lead screw is provided with a manually adjustable end.

[0017] The construction process for laying pipes using support devices for connecting municipal sewage pipes is as follows:

[0018] If three socket-type cement pipes need to be excavated, they should be named Pipe 1, Pipe 2, and Pipe 3. Pipe 2 is located between Pipe 1 and Pipe 3. The socket-type cement pipe needs to be replaced with Pipe 2. The adjustment support mechanisms corresponding to the three socket-type cement pipes can be named Support 1, Support 2, and Support 3 respectively.

[0019] (1) The excavation equipment excavates the soil at the three socket cement pipes and removes the soil around pipe 1, pipe 2 and pipe 3. Pipe 2 is broken and removed. Then, the hoisting equipment is used to lift pipe 1 and pipe 3 away from their original positions.

[0020] (2) The excavation equipment continued to excavate pits of a certain depth at pipe 1, pipe 2 and pipe 3;

[0021] (3) The angle adjustment mechanism of support one is placed in the pit of pipe one. The pipe one is placed on the angle adjustment mechanism using hoisting equipment. The main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is hoisted. The hoisting mechanism is started to lift the pipe one through the angle adjustment mechanism. When the pipe one is lifted to the same level as the unexcavated socket cement pipe in the pit, the pipe one is pushed to one side manually or by equipment so that one end of the pipe one is connected to the unexcavated socket cement pipe on one side of the pit. The angle adjustment mechanism is started to adjust the angle of the pipe one to a certain angle. The pipe one is fixed on the angle adjustment mechanism through the fixing mechanism.

[0022] (4) The angle adjustment mechanism of support 2 is placed in the pit of pipe 2. The hoisting equipment is used to place pipe 1 on the angle adjustment mechanism. The main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is hoisted. The hoisting mechanism is started to lift pipe 2 through the angle adjustment mechanism. When pipe 2 is lifted to the same horizontal height as the other end of pipe 1, one end of pipe 2 is pushed to one side manually or by the equipment so that one end of pipe 2 is connected to the unexcavated socket cement pipe in the pit. The fixing mechanism fixes pipe 2 on the angle adjustment mechanism.

[0023] (5) The angle adjustment mechanism of support three is placed in the pit of pipe three. The hoisting equipment is used to place pipe three on the angle adjustment mechanism. The main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is hoisted. The hoisting mechanism lifts pipe three through the angle adjustment mechanism. When pipe three is lifted to the same level as the unexcavated socket cement pipe in the tunnel, the pipe three is pushed to the other side manually or by the equipment so that one end of pipe three is connected to the unexcavated socket cement pipe on the other side of the tunnel. At this time, the other end of pipe three is connected to the other end of pipe two. The fixing mechanism fixes pipe three on the angle adjustment mechanism.

[0024] (6) The angle adjustment mechanisms on supports one, two and three move down at the same time. The descent speed is adjusted according to the height angle adjustment mechanism. When moving down, pipe one and pipe two change from an inclined state to a horizontal state. When they are in a horizontal state, pipe one, pipe two and pipe three are installed and connected.

[0025] Compared with the prior art, the advantages of this invention are as follows: This invention is a support device for connecting and installing municipal sewage pipelines, which has the following advantages:

[0026] 1. By setting up several adjusting support mechanisms to assist in the installation and connection of socket-type cement pipes, several socket-type cement pipes can be tilted to a certain angle under the drive of the angle adjustment mechanism. During installation and connection, several socket-type cement pipes are tilted and connected. After connection, several socket-type cement pipes are placed in the predetermined position. This can solve the problem that the original size socket-type cement pipes cannot be directly installed in the existing technology, and saves the building materials for building observation wells.

[0027] 2. Because the angle adjustment mechanism can be adjusted vertically and horizontally on the main support frame, this invention can replace not only underground socket-type cement pipes but also socket-type cement pipes on the ground, thus expanding the scope of application of this invention. Furthermore, by inserting the uprights into the ground, the invention can be prevented from shifting during operation, and the support base can be used to support the invention, which can greatly increase its stability.

[0028] 3. An angle adjustment mechanism is installed. A groove is set on the support rod, and the connector can move in the groove. When it is necessary to fix the rotation angle of the hinge plate, the limit plate can be pushed to the groove side by the handle, so that the limit plate and the limit rod are engaged. When the hinge plate is rotated in the opposite direction, the limit plate and the limit rod are the supporting objects. Since the hinge plate is fixed, the connector slides in the groove. At this time, the supporting force between the screw block and the hinge plate disappears, avoiding damage to the mechanical transmission components in the angle adjustment mechanism due to long-term heavy pressure on the socket cement pipe.

[0029] 4. This invention adjusts the angle of the support mechanism and the hoisting mechanism to lift and tilt the socket-type cement pipes one by one, reducing the horizontal length of the socket-type cement pipes during the process. Then, all the socket-type cement pipes are lowered at the same time, so that all the socket-type cement pipes can be installed and connected at the same time. That is, when replacing the original size socket-type cement pipes, the existing construction process of replacing socket-type cement pipes due to damage is changed, and socket-type cement pipes of the same size can be installed.

Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 As shown, a support device for connecting and installing municipal sewage pipes includes several adjustable support mechanisms that allow socket-type cement pipes to be tilted and connected. The adjustable support mechanism includes a main support frame 1, on which a hoisting mechanism 2 is provided. The end of the hoisting mechanism 2 is connected to an angle adjustment mechanism 3 located inside the main support frame 1. The socket-type cement pipe is located on the angle adjustment mechanism 3, and the angle adjustment mechanism 3 can adjust the inclination angle of the socket-type cement pipe. The angle adjustment mechanism 3 is provided with a fixing mechanism 4 that can fix the socket-type cement pipe.

[0043] Several adjustment and support mechanisms can support and adjust the installation of individual socket-type cement pipes. The main support frame 1 serves as the support device of this invention. The hoisting mechanism 2 can change the height of the socket-type cement pipe by changing the height of the angle adjustment mechanism 3. The angle adjustment mechanism 3 can change the inclination angle of the socket-type cement pipe, which facilitates the subsequent installation of several socket-type cement pipes. The fixing mechanism 4 can fix the socket-type cement pipe on the angle adjustment mechanism 3 to prevent it from slipping.

[0044] Combined with appendix Figure 5 Appendix Figure 7 Appendix Figure 9 Appendix Figure 10As shown, the main support frame 1 includes a top plate 101, the hoisting mechanism 2 is fixed to the top plate 101, and a plurality of uprights 106 are slidably inserted through the top plate 101, the uprights 106 being vertically inserted into the ground. The angle adjustment mechanism 3 includes a base plate 301, the base plate 301 having an end block 312 slidably connected to the uprights 106, and a hinge plate 302 hinged to one end of the base plate 301. The hinge plate 302 has a plurality of mounting holes 303. The connecting plate 302 is provided with two pipe pads 304, and the socket-type cement pipe is located on the pipe pads 304. The base plate 301 is provided with a threaded rod 306, and a screw block 315 is threadedly connected to the threaded rod 306. Both ends of the screw block 315 are provided with connectors 316. The bottom of the hinge plate 302 is hinged with two support rods 317. The end of the support rod 317 is provided with a sliding groove 318, and the connector 316 is located in the sliding groove 318 and is slidably connected to the sliding groove 318.

[0045] The base plate 301 is provided with two grooves 309 located on both sides of the lead screw 306. A limiting plate 310 is slidably provided in the grooves 309. The bottom of the hinge plate 302 is hinged with a limiting rod 308 located on both sides of the two support rods 317. The two limiting rods 308 are respectively engaged with the two limiting plates 310. The end of the limiting plate 310 is provided with a connecting plate 311 that passes through the base plate 301. The connecting plate 311 is provided with a handle 314 to facilitate the disengagement of the limiting plate 310 from the limiting rods 308.

[0046] The base plate 301 is provided with a pad 313. When the hinge plate 302 contacts the pad 313, it is in a horizontal state. The end of the lead screw 306 is provided with a manually adjustable end head 307.

[0047] Before replacing the socket-type cement pipe, since several socket-type cement pipes need to be installed together, the damaged socket-type cement pipe needs to be dug out and several socket-type cement pipes on both sides of it need to be dug out as well. Then, a certain depth needs to be dug to facilitate the placement of the angle adjustment mechanism 3. This process can be carried out using engineering equipment such as excavators.

[0048] In this invention, when replacing socket-type cement pipes, the corresponding socket-type cement pipes are sequentially connected one by one through several adjusting support mechanisms, and then all socket-type cement pipes are simultaneously lowered into position to complete the installation. Specifically:

[0049] Several base plates 301 are placed at the corresponding positions of the socket-type cement pipes. The angle adjustment mechanism 3 of the main support frame 1 is moved to a different position and inserted into the ground through the end block 312 via the pile 106. The hoisting mechanism 2 is started to drive the angle adjustment mechanism 3 to rise. When it rises to the predetermined position, the socket-type cement pipe is placed on the pipe pad 304, and the socket-type cement pipe on the pipe pad 304 is connected with the socket-type cement pipe that has not been excavated in the tunnel. The socket-type cement pipe is fixed to the angle adjustment mechanism 3 by the fixing mechanism 4. At this time, the angle adjustment mechanism 3 at the outermost edge can be adjusted. The adjusting end 307 is rotated, which drives the screw 306 to rotate. The screw 306 drives the screw block 315 to move. The screw block 315 abuts against the slide groove 318 through the connector 316, driving the support rod 317 to hinge relative to the hinge plate 302. At this time, the hinge plate 302 can drive the socket cement pipe to rotate. After the socket cement pipe rotates to a certain angle, the adjustment support mechanism is placed to lift and connect the subsequent socket cement pipes. After the socket cement pipes are placed, the corresponding hinge plate 302 needs to be adjusted in terms of rotation angle and height. The socket cement pipe in the center does not need to be rotated, but only needs to be raised and connected to the socket cement pipes on both sides. After all the socket cement pipes have been adjusted and connected, the fixing mechanism 4 can be removed or loosened to facilitate the movement of several socket cement pipes when they are moved down and connected.

[0050] After all the socket-type cement pipes are connected, the hoisting mechanism 2 is started simultaneously. Since the heights of the socket-type cement pipes are different, the power of the hoisting mechanism 2 needs to be adjusted according to the height. During the descent, the adjusting end 307 needs to be rotated in the opposite direction to make the socket-type cement pipes gradually move towards a horizontal state. The adjusting end 307 of this invention is manually operated and can be replaced by a drive motor for easy operation until the socket-type cement pipes are in a horizontal state. At this time, all the socket-type cement pipes can be installed and connected.

[0051] Combined with appendix Figure 8 As shown, the fixing mechanism 4 includes a rope locking device 401, which is located above the socket-type cement pipe. Both ends of the rope locking device 401 are provided with locking ropes 402 located outside the socket-type cement pipe. The locking ropes 402 pass through the mounting hole 303, and each end of the two locking ropes 402 is provided with a connecting hook 403, which is connected to each other.

[0052] When fixing the socket-type cement pipe onto the hinge plate 302, the rope locking device 401 is placed on the socket-type cement pipe, and the locking rope 402 is passed through the mounting hole 303. The two connecting hooks 403 passing through the mounting hole 303 hook each other. At this time, the rope locking device 401 can be adjusted to tighten the locking rope 402 to achieve the purpose of fixing the socket-type cement pipe onto the hinge plate 302. The rope locking device 401 is existing technology and generally consists of a shell, an operating handle, a wire take-up mechanism, and a wire release mechanism.

[0053] Combined with appendix Figure 3 Appendix Figure 4 Appendix Figure 6 As shown, the top plate 101 is provided with several electric telescopic rods 102 on both sides, which can increase the span of the adjustable support mechanism. Each of the electric telescopic rods 102 is provided with an electric telescopic rod 103 at its end. The bottom of the electric telescopic rod 103 is provided with a support seat 104, and the support seat 104 is provided with a retractable caster wheel 105.

[0054] When placing the main support frame 1, the electric telescopic rod 102 can be activated to extend and retract to adjust the distance between the support seats 104 to accommodate excavation tunnels with different spans. The electric telescopic rod 103 can be activated to extend and retract to adjust the height of the top plate 101 to cope with excavation tunnels of different depths. When the main support frame 1 needs to be moved, the retractable casters 105 inside the support seats 104 can extend out of the support seats 104, at which time the main support frame 1 can be moved.

[0055] Combined with appendix Figure 5 Appendix Figure 6 As shown, the hoisting mechanism 2 includes a double rope roller 201. A driving device is provided on one side of the double rope roller 201. Two hoisting ropes 202 with the same winding direction but opposite output directions are provided on the outside of the double rope roller 201. Two correction frames are provided on the top plate 101. An auxiliary wheel 107 is provided on one side of the correction frame 203. The hoisting ropes 202 extend downward through the correction frame 203 and the auxiliary wheel 107. A connecting hook 204 connected to the bottom plate 301 is provided at the bottom end.

[0056] When the hoisting mechanism 2 is started, starting the drive device to rotate forward will cause the double rope roller 201 to release the hoisting rope 202, and starting the drive device to rotate in reverse will cause the double rope roller 201 to tighten the hoisting rope 202. Since the two hoisting ropes 202 are located at both ends of the double rope roller 201, the output end of the hoisting rope 202 cannot be located at the center of the double rope roller 201. When the hoisting rope 202 passes through the correction frame 203, the hoisting rope 202 can be located at the center of the double rope roller 201, which can prevent the hoisting rope 202 from detaching from the auxiliary wheel 107.

[0057] Combined with appendix Figure 7As shown, the pipe gasket 304 is fixedly connected to the hinge plate 302 by bolts passing through the mounting hole 303. The pipe gasket 304 is provided with a plurality of rotating wheels 305, and the rotating wheels 305 are in rolling connection with the socket-type cement pipe.

[0058] The distance between the two pipe gaskets 304 can be adjusted according to the mounting holes 303. The rotating wheel 305 can assist in moving the socket-type cement pipes during the installation and docking process.

[0059] The construction process for laying pipes using support devices for connecting municipal sewage pipes is as follows:

[0060] If three socket-type cement pipes need to be excavated, they should be named Pipe 1, Pipe 2, and Pipe 3. Pipe 2 is located between Pipe 1 and Pipe 3. The socket-type cement pipe needs to be replaced with Pipe 2. The adjustment support mechanisms corresponding to the three socket-type cement pipes can be named Support 1, Support 2, and Support 3 respectively.

[0061] (1) The excavation equipment excavates the soil at the three socket cement pipes and removes the soil around pipe 1, pipe 2 and pipe 3. Pipe 2 is broken and removed. Then, the hoisting equipment is used to lift pipe 1 and pipe 3 away from their original positions.

[0062] (2) The excavation equipment continued to excavate pits of a certain depth at pipe 1, pipe 2 and pipe 3;

[0063] (3) The angle adjustment mechanism 3 of the support is placed in the pit of the pipe. The pipe is placed on the angle adjustment mechanism 3 using hoisting equipment. The main support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is hoisted. The hoisting mechanism 2 is started to lift the pipe through the angle adjustment mechanism 3. When the pipe is lifted to the same level as the unexcavated socket cement pipe in the pit, the pipe is pushed to one side manually or by equipment so that one end of the pipe is connected to the unexcavated socket cement pipe on one side of the pit. The angle adjustment mechanism 3 is started to adjust the angle of the pipe to a certain angle. The pipe is fixed on the angle adjustment mechanism 3 by the fixing mechanism 4.

[0064] (4) The angle adjustment mechanism 3 of the support is placed in the pit of the pipe. The pipe is placed on the angle adjustment mechanism 3 using the hoisting equipment. The support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is hoisted. The hoisting mechanism 2 is started to lift the pipe through the angle adjustment mechanism 3. When the pipe is lifted to the same level as the other end of the pipe, the pipe is pushed to one side manually or by the equipment so that the pipe is connected to the unexcavated socket cement pipe in the pit. The fixing mechanism 4 fixes the pipe on the angle adjustment mechanism 3.

[0065] (5) The angle adjustment mechanism 3 of the support is placed in the pit of the pipe. The pipe is placed on the angle adjustment mechanism 3 using hoisting equipment. The support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is hoisted. The hoisting mechanism 2 lifts the pipe through the angle adjustment mechanism 3. When the pipe is lifted to the same level as the unexcavated socket cement pipe in the pit, the pipe is pushed to the other side manually or by equipment so that one end of the pipe is connected to the unexcavated socket cement pipe on the other side of the pit. At this time, the other end of the pipe is connected to the other end of the pipe. The fixing mechanism 4 fixes the pipe on the angle adjustment mechanism 3.

[0066] (6) The angle adjustment mechanism 3 on support one, support two and support three moves down at the same time. The descent speed is adjusted according to the height angle adjustment mechanism 3. When moving down, pipe one and pipe two change from the inclined state to the horizontal state. When in the horizontal state, pipe one, pipe two and pipe three are installed and connected.

[0067] Detailed Implementation: The present invention provides a support device for connecting and installing municipal sewage pipes. When using the present invention to replace and connect damaged socket-type cement pipes:

[0068] The damaged socket-type cement pipe is excavated, along with several other socket-type cement pipes on both sides. Excavation continues to a certain depth. The angle adjustment mechanism 3 is placed at the corresponding position on the socket-type cement pipe. The main support frame 1 is aligned with the angle adjustment mechanism 3 and inserted into the ground via the vertical pile 106. The hoisting mechanism 2 is activated to lift the angle adjustment mechanism 3. When it reaches the predetermined position, the socket-type cement pipe is placed and aligned with the existing socket-type cement pipe on the ground. The fixing mechanism 4 secures the socket-type cement pipe to the angle adjustment mechanism 3. At this point, the adjustable part is at its outermost position. The angle adjustment mechanism 3 is used to rotate the socket cement pipe at a certain angle. The adjustment support mechanism is then placed to connect and rotate the subsequent socket cement pipes. The socket cement pipe in the center does not need to be rotated; it only needs to be raised and connected to the socket cement pipes on both sides that are tilted. After all the socket cement pipes have been adjusted and connected, the fixing mechanism 4 can be removed or loosened. At the same time, the hoisting mechanism 2 is started intermittently. The hoisting mechanism 2 makes the socket cement pipes gradually tend to be horizontal until the socket cement pipes are horizontal. At this time, all socket cement pipes can be installed and connected.

[0069] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
