Description

Technical Field

[0001] The invention relates to the technical field of sewage pipes, and in particular to a supporting device for butt-jointing installation of municipal sewage pipes. Background Art

[0002] Sewage pipes are composed of pipes and their ancillary structures for collecting and transporting urban sewage. Sewage flows from branch pipes into trunk pipes, then into main pipes, and finally into sewage treatment plants. The pipes are distributed from small to large, similar to rivers and in a tree-like shape. They are completely different from the circulation and penetration of water supply networks. Sewage generally flows from high to low in the pipes due to the water level difference at both ends of the pipes. The inside of the pipes is not under pressure, that is, it flows by gravity.

[0003] The support device for the connection and installation of municipal sewage pipes is an auxiliary equipment used in pipeline construction. It can help construction workers to complete the connection and installation of pipes efficiently and accurately. The support device is usually composed of a fixed plate, a support rod, a mounting frame and other parts. It can provide support for the connection and installation of pipes, and the support height can be adjusted according to actual needs to adapt to the installation of pipes of different diameters and lengths.

[0004] In the prior art, the steps for replacing a socket-and-spigot cement pipe after it is damaged are: use excavation equipment to dig the pipe, then take out the damaged pipe, and when the damaged pipe is close to the inspection well, the inspection well and the pipes between them need to be removed together, and the damaged pipe is replaced and the remaining pipes are reinstalled, and then the inspection well is rebuilt; When the damaged pipe is not near the inspection well, it needs to be removed. This application is for the replacement of the spigot-and-socket cement pipe, and the spigot-and-socket cement pipe connection method is sequential plug-in. After the pipe is removed, the installation length space left will be less than the length of the spigot-and-socket cement pipe, resulting in the inability to directly install and connect the pipe; Since both ends of the socket-and-spigot cement pipe are plug-in connections, the prior art cannot directly install a socket-and-spigot cement pipe of the original length due to limited installation dimensions after the original damaged socket-and-spigot cement pipe is removed. Only a socket-and-spigot cement pipe of a smaller length can be installed after removal, and a gap still remains. In the prior art, an inspection well is built at the gap, and the inspection well is not inspected regularly, which increases the construction materials for the maintenance of the socket-and-spigot cement pipe and wastes manpower to inspect the inspection well later.

[0012] As an improvement, a cushion block is provided on the bottom plate, and the hinged plate is in a horizontal state when in contact with the cushion block, and a manually adjustable adjustment end is provided at the end of the screw rod.

[0013] The construction process of laying pipes using the support device for municipal sewage pipe docking installation is as follows: If three socket-and-spigot cement pipes need to be excavated, the three socket-and-spigot cement pipes are named pipe one, pipe two, and pipe three. Pipe two is located between pipe one and pipe three, and the socket-and-spigot cement pipe needs to be replaced with pipe two. The corresponding adjustment support mechanisms of the three socket-and-spigot cement pipes can be named support one, support two, and support three; (1) Use excavation equipment to excavate the soil layer at the three socket-type cement pipes, and remove the soil around pipes 1, 2, and 3. Break and remove pipe 2, and then use lifting equipment to lift pipes 1 and 3 away from their original positions one by one; (2) The excavation equipment continues to dig a pit of a certain depth at pipes 1, 2, and 3; (3) The angle adjustment mechanism of support one is placed in the earth pit of pipe one, and pipe one is placed on the angle adjustment mechanism using a lifting device. The main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is lifted. The lifting mechanism is started to lift pipe one through the angle adjustment mechanism. When pipe one is lifted to the same level as the unexcavated socket-and-spigot cement pipe in the tunnel, pipe one is pushed to one side manually or by equipment so that one end of pipe one is connected to the unexcavated socket-and-spigot cement pipe on one side of the tunnel. The angle adjustment mechanism is started to adjust the angle of pipe one to a certain angle, and pipe one is fixed to the angle adjustment mechanism by a fixing mechanism. (4) The angle adjustment mechanism of support 2 is placed in the earth pit of pipe 2, pipe 1 is placed on the angle adjustment mechanism using a lifting device, the main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is lifted, the lifting mechanism is started to lift pipe 2 through the angle adjustment mechanism, and when pipe 2 is lifted to the same level as the other end of pipe 1, one end of pipe 2 is pushed to one side manually or by equipment so that one end of pipe 2 is butted against the unexcavated socket-and-spigot cement pipe in the tunnel, and the fixing mechanism fixes pipe 2 on the angle adjustment mechanism; (5) The angle adjustment mechanism of support three is placed in the earth pit of pipe three. Pipe three is placed on the angle adjustment mechanism using a lifting device. The main support frame is moved to the top of the angle adjustment mechanism and the angle adjustment mechanism is lifted. The lifting mechanism lifts pipe three through the angle adjustment mechanism. When pipe three is lifted to the same level as the unexcavated socket-and-spigot cement pipe in the tunnel, pipe three is pushed to the other side manually or by equipment so that one end of pipe three is butted against the unexcavated socket-and-spigot cement pipe on the other side of the tunnel. At this time, the other end of pipe three is butted against the other end of pipe two. The fixing mechanism fixes pipe three on the angle adjustment mechanism. (6) The angle adjustment mechanisms on support 1, support 2, and support 3 move downward at the same time, and the descending speed is adjusted according to the height angle adjustment mechanism. When moving downward, pipe 1 and pipe 2 change from an inclined state to a horizontal state. When in a horizontal state, pipe 1, pipe 2, and pipe 3 are installed and docked.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention is a supporting device for butt-jointed installation of municipal sewage pipes, which has the following advantages: 1. By setting up several adjustment support mechanisms to assist the installation and docking of the socket-type cement pipes, several socket-type cement pipes can be tilted to a certain angle under the drive of the angle adjustment mechanism, and several socket-type cement pipes can be tilted and docked during installation and docking. After docking, several socket-type cement pipes can be placed in predetermined positions at the same time, which can solve the problem that the original size socket-type cement pipes cannot be directly installed in the prior art, and save the construction materials for building the observation well.

[0015] 2. Since the angle adjustment mechanism can be adjusted up and down on the main support frame, the present invention can not only replace the underground socket-type cement pipes, but also replace the socket-type cement pipes on the ground, which expands the scope of application of the present invention. By inserting the piles into the ground, the present invention can be prevented from being offset during operation, and the support seat is used to support the present invention, which can greatly increase the stability.

[0016] 3. An angle adjustment mechanism is set by setting a slide groove on the support rod. At this time, the connecting head can move in the slide groove. When the rotation angle of the hinged plate needs to be fixed, the limit clamping plate can be pushed to one side of the groove through the handle to make the limit clamping plate and the limit clamping rod engage. At this time, when the hinged plate is rotated in the opposite direction, the limit clamping plate and the limit clamping rod are supported. Since the hinged plate is fixed, the connecting head slides in the slide groove. At this time, the supporting force between the screw block and the hinged plate disappears, avoiding long-term heavy pressure on the angle adjustment mechanism of the socket-type cement pipe, which may cause damage to the mechanical transmission components in the angle adjustment mechanism.

[0017] 4. The present invention adjusts the angle adjustment mechanism and the lifting mechanism of the supporting 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, and then drives all the socket-type cement pipes to descend at the same time, so that all the socket-type cement pipes can complete the installation and docking work at the same time, that is, when replacing the socket-type cement pipes of the original size, the construction process of replacing the existing socket-type cement pipes due to damage is changed, and the socket-type cement pipes of the same size can be installed.

The angle adjustment mechanism 3 can change the inclination angle of the socket-type cement pipe, which is convenient for the subsequent docking and 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.

[0031] Combined with Figure 5 , Attachment Figure 7 , Attachment Fig. 9 , Attachment Fig.10As shown, the supporting main frame 1 includes a top plate 101, the hoisting mechanism 2 is fixed on the top plate 101, a plurality of piles 106 are slidably penetrated on the top plate 101, and the piles 106 are vertically inserted into the ground, and the angle adjustment mechanism 3 includes a bottom plate 301, and the bottom plate 301 is provided with an end block 312 slidably connected to the piles 106, and one end of the bottom plate 301 is hinged with a hinge plate 302, and the hinge plate 302 is provided with a plurality of mounting holes 303. Two pipe cushions 304 are provided on the connecting plate 302, and the spigot-and-socket cement pipe is located on the pipe cushions 304. A screw rod 306 is provided on the bottom plate 301, and a screw block 315 is threadedly connected to the screw rod 306. Both ends of the screw block 315 are provided with connectors 316. Two support rods 317 are hinged at the bottom of the hinged plate 302, and a slide groove 318 is provided at the end of the support rod 317. The connector 316 is located in the slide groove 318 and is slidably connected to the slide groove 318. The bottom plate 301 is provided with two grooves 309 located on both sides of the screw rod 306, and a limit clamping plate 310 is slidably provided in the groove 309. The bottom of the hinged plate 302 is hinged with a limit clamping rod 308 located on both sides of the two support rods 317. The two limit clamping rods 308 are respectively clamped with two limit clamping plates 310. The end of the limit clamping plate 310 is provided with a connecting plate 311 passing through the bottom plate 301, and the connecting plate 311 is provided with a handle 314 for facilitating the separation of the limit clamping plate 310 and the limit clamping rod 308. The bottom plate 301 is provided with a cushion block 313, and the hinge plate 302 is in a horizontal state when in contact with the cushion block 313. The end of the screw rod 306 is provided with a manually adjustable adjustment end 307; Before replacing the socket-and-spigot cement pipe, since several socket-and-spigot cement pipes need to be installed together, it is necessary to dig out the damaged socket-and-spigot cement pipe and several socket-and-spigot cement pipes on both sides thereof, and then continue to dig to a certain depth to facilitate the placement of the angle adjustment mechanism 3. This process can use engineering equipment such as an excavator; When replacing the spigot-and-socket cement pipe, the present invention connects the corresponding spigot-and-socket cement pipes one by one in sequence through a plurality of adjusting support mechanisms, and at the same time lowers all the spigot-and-socket cement pipes into place to complete the installation, specifically: Place a number of bottom plates 301 at the corresponding positions of the socket-and-spigot cement pipes, so that the corresponding angle adjustment mechanism 3 of the supporting main frame 1 is shifted and inserted into the ground through the pile 106 through the end block 312, and the hoisting mechanism 2 is started to drive the angle adjustment mechanism 3 to rise. When it rises to the predetermined position, the socket-and-spigot cement pipe is placed on the pipe cushion 304, and the socket-and-spigot cement pipe on the pipe cushion 304 is docked with the socket-and-spigot cement pipe that has not been dug out in the tunnel, and the socket-and-spigot cement pipe is fixed on the angle adjustment mechanism 3 through the fixing mechanism 4. At this time, the angle adjustment mechanism 3 at the edge can be adjusted, and the adjusting end 307 is rotated. The adjusting end 307 drives the screw rod 306 to rotate, and the screw rod 306 drives the screw block 315 to move The screw block 315 pushes the slide groove 318 against the driving support rod 317 to hinge relative to the hinge plate 302 through the connecting head 316. At this time, the hinge plate 302 can drive the socket-type cement pipe to flip. When the socket-type cement pipe flips to a certain angle, the adjustment support mechanism is continued to be placed to lift and dock the subsequent socket-type cement pipes. After the socket-type cement pipes are placed, the corresponding flip angle and height of the hinge plate 302 need to be adjusted. The socket-type cement pipe at the center does not need to be flipped, only the height needs to be lifted and the inclined socket-type cement pipes on both sides need to be docked. After all the socket-type cement pipes that have been adjusted are docked, the fixing mechanism 4 can be removed or loosened to facilitate the movement of several subsequent socket-type cement pipes when they are moved down and fully docked. After all the socket-type cement pipes are butt-jointed, the lifting mechanism 2 is started at the same time. Since the heights of several socket-type cement pipes are different, the power of the lifting mechanism 2 needs to be changed according to the height. During the downward movement, the adjusting end 307 needs to be rotated in the opposite direction so that the socket-type cement pipes gradually tend to a horizontal state. The adjusting end 307 of the present invention is manually operated and can be replaced by a driving 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 butt-jointed.

[0032] Combined with Figure 8 As shown, the fixing mechanism 4 includes a rope lock 401, the rope lock 401 is located above the socket-type cement pipe, and locking ropes 402 located outside the socket-type cement pipe are provided at both ends. The locking ropes 402 pass through the mounting hole 303, and the ends of the two locking ropes 402 are both provided with connecting hooks 403, and the two connecting hooks 403 are connected to each other; When the socket-and-spigot cement pipe is fixed on the hinged plate 302, the rope lock 401 is placed on the socket-and-spigot cement pipe, and the locking rope 402 is passed through the mounting hole 303, and the two connecting hooks 403 passing through the mounting hole 303 are hooked with each other. At this time, the rope lock 401 can be adjusted to tighten the locking rope 402 to achieve the purpose of fixing the socket-and-spigot cement pipe on the hinged plate 302. The rope lock 401 belongs to the prior art and is generally composed of a shell, an operating handle, a wire-reeling mechanism and a wire-releasing mechanism.

[0033] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 6 As shown, a plurality of electric telescopic rods 102 are provided on both sides of the top plate 101 to increase the span of the adjustable support mechanism, and a plurality of electric telescopic rods 102 are provided at the ends of the electric telescopic rods 102. A support seat 104 is provided at the bottom of the electric telescopic rods 103, and a retractable universal wheel 105 is provided in the support seat 104. When placing the supporting main frame 1, the electric telescopic rod 102 can be started to extend and retract to adjust the distance between the supporting seats 104 to adapt to excavation tunnels with different spans. The electric telescopic rod 2 103 can be started to extend and retract to adjust the height of the top plate 101 to cope with excavation tunnels of different depths. When the retractable universal wheel 105 in the supporting seat 104 needs to be moved, the universal wheel 105 can extend out of the supporting seat 104, and the placed supporting main frame 1 can be moved at this time.

[0034] Combined with Figure 5 , Attachment Figure 6 As shown, the hoisting mechanism 2 includes a double rope drum 201, one side of the double rope drum 201 is provided with a driving device, the double rope drum 201 is provided with two ropes 202 with the same winding direction but opposite output ends, the top plate 101 is provided with two correction frames, one side of the correction frame 203 is provided with an auxiliary wheel 107, the rope 202 passes through the correction frame 203 and the auxiliary wheel 107 and extends downward, and the bottom end is provided with a connecting hook 204 connected to the bottom plate 301; When the hoisting mechanism 2 is started, the driving device is started to rotate forward to make the double-rope drum 201 release the rope 202, and the driving device is started to rotate backward to make the double-rope drum 201 tighten the rope 202. Since the two ropes 202 are located at both ends of the double-rope drum 201, the output end of the rope 202 cannot be located at the center of the double-rope drum 201 at this time. When the rope 202 passes through the correction frame 203, the rope 202 can be located at the center of the double-rope drum 201, which can prevent the rope 202 from being separated from the auxiliary wheel 107.

[0035] Combined with Figure 7 As shown, the pipe cushion 304 is fixedly connected to the hinge plate 302 by bolts passing through the mounting holes 303, and a plurality of runners 305 are provided on the pipe cushion 304, and the runners 305 are rollingly connected to the spigot-and-socket cement pipe; The distance between the two pipe gaskets 304 can be adjusted according to the installation hole 303, and the rotating wheel 305 can assist the movement of the socket-type cement pipes during the installation and docking of several socket-type cement pipes.

[0036] The construction process of laying pipes using the support device for municipal sewage pipe docking installation is as follows: If three socket-and-spigot cement pipes need to be excavated, the three socket-and-spigot cement pipes are named pipe one, pipe two, and pipe three. Pipe two is located between pipe one and pipe three, and the socket-and-spigot cement pipe needs to be replaced with pipe two. The corresponding adjustment support mechanisms of the three socket-and-spigot cement pipes can be named support one, support two, and support three; (1) Use excavation equipment to excavate the soil layer at the three socket-type cement pipes, and remove the soil around pipes 1, 2, and 3. Break and remove pipe 2, and then use lifting equipment to lift pipes 1 and 3 away from their original positions one by one; (2) The excavation equipment continues to dig a pit of a certain depth at pipes 1, 2, and 3; (3) The angle adjustment mechanism 3 of support one is placed in the earth pit of pipe one, and pipe one is placed on the angle adjustment mechanism 3 using a lifting device. The main support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is lifted. The lifting mechanism 2 is started to lift pipe one through the angle adjustment mechanism 3. When pipe one is lifted to the same level as the unexcavated socket-and-spigot cement pipe in the tunnel, pipe one is pushed to one side manually or by equipment so that one end of pipe one is connected to the unexcavated socket-and-spigot cement pipe on one side of the tunnel. The angle adjustment mechanism 3 is started to adjust the angle of pipe one to a certain angle, and pipe one is fixed to the angle adjustment mechanism 3 by the fixing mechanism 4. (4) The angle adjustment mechanism 3 of support 2 is placed in the earth pit of pipe 2, and pipe 1 is placed on the angle adjustment mechanism 3 using a lifting device. The main support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is lifted. The lifting mechanism 2 is started to lift pipe 2 through the angle adjustment mechanism 3. When pipe 2 is lifted to the same level as the other end of pipe 1, one end of pipe 2 is pushed to one side manually or by equipment so that one end of pipe 2 is connected to the unexcavated socket-type cement pipe in the tunnel, and the fixing mechanism 4 fixes pipe 2 on the angle adjustment mechanism 3. (5) The angle adjustment mechanism 3 of support three is placed in the earth pit of pipe three, and pipe three is placed on the angle adjustment mechanism 3 using a lifting device. The main support frame 1 is moved to the top of the angle adjustment mechanism 3 and the angle adjustment mechanism 3 is lifted. The lifting mechanism 2 lifts pipe three through the angle adjustment mechanism 3. When pipe three is lifted to the same level as the unexcavated socket-and-spigot cement pipe in the tunnel, pipe three is pushed to the other side manually or by equipment so that one end of pipe three is butted against the unexcavated socket-and-spigot cement pipe on the other side of the tunnel. At this time, the other end of pipe three is butted against the other end of pipe two, and the fixing mechanism 4 fixes pipe three on the angle adjustment mechanism 3. (6) The angle adjustment mechanisms 3 on the support 1, support 2, and support 3 move downward at the same time, and the descending speed is adjusted according to the height angle adjustment mechanism 3. When moving downward, the pipes 1 and 2 are changed from an inclined state to a horizontal state. When they are in a horizontal state, the pipes 1, 2, and 3 are installed and docked.

[0037] Specific implementation method: The present invention provides a support device for municipal sewage pipe docking installation. When the present invention is used to replace and install a damaged socket-type cement pipe: Dig out the damaged socket-and-spigot cement pipe and several socket-and-spigot cement pipes on both sides of it, then continue digging to a certain depth, place the angle adjustment mechanism 3 at the corresponding position of the socket-and-spigot cement pipe, make the supporting main frame 1 correspond to the position of the angle adjustment mechanism 3 and insert it into the ground through the pile 106, start the hoisting mechanism 2 to drive the angle adjustment mechanism 3 to rise, and when it rises to the predetermined position, place the socket-and-spigot cement pipe and connect it with the socket-and-spigot cement pipe on the ground, and fix the socket-and-spigot cement pipe on the angle adjustment mechanism 3 through the fixing mechanism 4. At this time, the angle adjustment mechanism 3 can be adjusted to the edge. The angle adjustment mechanism 3 of the edge, at this time the socket-type cement pipe is flipped at a certain angle, and the adjustment support mechanism is continued to be placed to dock and flip the subsequent socket-type cement pipes. The socket-type cement pipe at the center does not need to be flipped, only the height needs to be lifted and the inclined socket-type cement pipes on both sides need to be docked. After all the adjusted socket-type cement pipes are docked, the fixing mechanism 4 can be removed or loosened, and the lifting mechanism 2 is started intermittently at the same time. The start of the lifting mechanism 2 makes the socket-type cement pipe gradually tend to a horizontal state until the socket-type cement pipe is in a horizontal state. At this time, all the socket-type cement pipes can be installed and docked.
