Therefore, they should not be construed as limitations on this invention.

[0031] like Figures 1-8 As shown, this invention provides a municipal engineering pipeline construction device for installing double-wall corrugated pipes in trenches. One end of the double-wall corrugated pipe is a socket end, and the other end is a spigot end. The device includes:

[0032] A walking device, which is installed on the trench;

[0033] The upper housing 100 is fixedly mounted on the traveling device to accommodate multiple double-walled corrugated pipes;

[0034] A guide mechanism 110 is disposed inside the upper housing 100 and divides the interior of the upper housing 100 into an upper cavity and a lower cavity. The guide mechanism 110 is used to guide a double-walled corrugated pipe from the upper cavity into the lower cavity.

[0035] A sealing mechanism is provided at one end of the lower cavity near the inlet end of the double-walled corrugated pipe, for fitting a sealing gasket onto the inlet end of the double-walled corrugated pipe.

[0036] The lower housing 200 is fixedly installed at the bottom of the upper housing 100 and communicates with the upper housing 100; the bottom of the lower housing 200 is open; the traveling device has a through groove through which the lower housing 100 can pass; the two ends inside the lower housing 200 are respectively provided with a socket lubrication device 230 and a socket lubrication device 220 corresponding to the socket end and the spigot end of the double-wall corrugated pipe; clamping and feeding devices 210 are respectively provided on both sides of the lower housing 200 parallel to its longitudinal axis; the clamping and feeding devices 210 are used to clamp the double-wall corrugated pipe in the lower housing 200, lower the double-wall corrugated pipe into the groove, and drive the double-wall corrugated pipe to connect with the double-wall corrugated pipe already installed in the groove.

[0037] In this technical solution, the walking device is a conventionally used trolley, including a chassis and wheel assemblies that drive the chassis to move. The walking device is used to move along both sides of the groove. The upper housing 100 is directly fixed or fixed to the chassis via a bracket. Multiple double-walled corrugated pipes are stored in the upper cavity of the upper housing 100, and one double-walled corrugated pipe is guided into the lower cavity by the guide mechanism 110. A sealing gasket is placed at the insertion end of the pipe in the lower cavity by the sealing mechanism, and then the pipe enters the lower housing 200. Preferably, the volume of the lower housing 200 is set to accommodate one double-walled corrugated pipe. A through slot can be opened on the chassis for the lower housing to pass through. Within the lower housing 200, the double-walled corrugated pipe is clamped and fixed by the clamping and feeding device 210. Lubricant is sprayed onto both ends of the double-walled corrugated pipe using the socket lubrication device 230 and the spigot lubrication device 220. The double-walled corrugated pipe is then lowered into the groove, aligning with the double-walled corrugated pipe already installed in the groove. Since the socket end of the double-walled corrugated pipe already installed in the groove was also lubricated within the lower housing 200 before installation, the spigot end of the double-walled corrugated pipe clamped and fixed by the clamping and feeding device 210 can be easily pushed into the socket end of the already installed double-walled corrugated pipe. After alignment, the traveling device continues to move forward along the groove to the next double-walled corrugated pipe installation position. In the above process, after the double-walled corrugated pipe in the lower cavity completes the sealing gasket installation and enters the lower box, the next double-walled corrugated pipe can be introduced into the lower cavity through the guide mechanism 110 to further improve construction efficiency.

[0038] In another embodiment, the sealing mechanism includes a clamping mechanism for fixing the double-walled bellows in the lower chamber and a fitting mechanism 130 for fitting a sealing gasket onto the insertion end of the double-walled bellows.

[0039] Specifically, refer to Figure 3 The clamping mechanism includes upper claw assemblies 120 symmetrically arranged on the inner walls of both sides of the lower cavity along the longitudinal axis of the lower cavity. The upper claw assembly 120 includes a first telescopic device 122 and an upper claw 121 horizontally arranged at the bottom of the lower cavity along the transverse axis of the upper housing 100. The upper claw 121 is arc-shaped to cooperate with the double-walled corrugated pipe. The fixed end of the first telescopic device 122 is fixedly connected to the lower cavity, and its movable end is fixedly connected to the upper claw 121.

[0040] The first telescopic devices 122 in the upper jaw assemblies 120 on both sides of the lower cavity extend simultaneously to clamp the double-walled corrugated pipe with both upper jaws. After the sealing gasket is installed, the first telescopic devices 122 on both sides retract simultaneously to release the double-walled corrugated pipe, allowing it to enter the lower housing 200. In actual use, a cross brace 122 can be provided between the first telescopic device 122 and the upper jaws 121, depending on the stroke of the first telescopic device 122 and the width of the upper housing 100. Multiple sets of clamping mechanisms can also be provided along the longitudinal axis of the lower cavity. Preferably, the upper jaws 121 are correspondingly engaged in the troughs on the outer wall of the double-walled corrugated pipe for more stable clamping of the double-walled corrugated pipe.

[0041] Reference Figure 4 and Figure 5 The sleeve mechanism includes a positioning annular plate 135, a pushing annular plate 134, a second telescopic device 131, and a third telescopic device 132. A through hole is provided on one side of the upper housing 100 near the insertion end of the double-walled corrugated pipe. The upper and lower ends of the positioning annular plate 135 are each provided with a second telescopic device 131. The fixed end of the second telescopic device 131 is fixedly connected to the inner wall of the upper housing 100, and its movable end is fixedly connected to the positioning annular plate 135. The positioning annular plate 135 is provided with multiple guide strips 133 along its circumference. Each guide strip 133 is perpendicular to one side of the positioning annular plate 135. One end of each guide strip 133 is hinged to the positioning annular plate 135, and a first tension spring is provided between the guide strip 133 and the positioning annular plate 135. Both ends of the first tension spring are fixedly connected to the positioning annular plate 135 and the guide strip 133, respectively. Under normal conditions, the first tension spring causes the guide strip 133 to be perpendicular to the positioning annular plate 135. The other end of the guide strip 133 passes through the through hole and extends out of the upper housing 100; the upper and lower ends of the push annular plate 134 are provided with the third telescopic device 132, the fixed end of the third telescopic device 132 is fixedly connected to the inner wall of the upper housing 100, and its movable end is fixedly connected to the push annular plate 134; the push annular plate 134 is movably sleeved on the outside of the guide strip 133 to push the sealing gasket from the guide strip 133 onto the double-walled corrugated pipe. The inner diameter of the positioning annular plate 131 is larger than the outer diameter of the double-walled corrugated pipe. The end face of the guide strip 133 facing the central axis of the positioning annular plate 131 is flush with the inner ring surface of the positioning annular plate 131. When the second telescopic device 131 and the third telescopic device 132 are extended, the positioning annular plate 135 and the pushing annular plate 134 are moved forward to the insertion end of the double-walled corrugated pipe. Each of the guide strips 133 can move to the outer periphery of the double-walled corrugated pipe, thereby moving the sealing gasket to the outer periphery of the double-walled corrugated pipe.

[0042] When using, refer to Figure 4 In the initial state, both the second telescopic device 131 and the third telescopic device 132 are retracted to their minimum travel state. At this time, the pushing annular plate 134 and the positioning annular plate 135 sequentially approach the inner wall of the upper housing 100, with a slight gap between the bottom surface of the pushing annular plate 134 and the top surface of each guide strip 133. First, the sealing gasket is manually placed on the outer periphery of each guide strip 133 on the outside of the upper housing 100. Since one end of each guide strip 133 is hinged to the positioning annular plate 135 and a first tension spring is provided between them, when placing the sealing gasket, each guide strip 133 can be pulled towards the central axis of the positioning annular plate 135, allowing the sealing gasket to be conveniently and quickly placed on each guide strip 133. Then, under the action of the first tension spring, each guide strip 133 returns to a state perpendicular to the positioning annular plate 135. Then, the second telescopic device 131 and the third telescopic device 132 extend simultaneously, moving the positioning annular plate 135 and the pushing annular plate 134 forward to the insertion end of the double-walled corrugated pipe. At this time, the guide strip 133 and the sealing gasket fitted on the guide strip 133 are also located on the outer periphery of the double-walled corrugated pipe. Then, the third telescopic device 132 retracts, stopping it in front of the expected position of the sealing gasket. The second telescopic device 131 continues to extend. When the sealing gasket touches the pushing annular plate 134, it stops moving forward with each of the guide strips 133 and finally detaches from the guide strip 133 and is fitted onto the double-walled corrugated pipe. The second telescopic device 131 stops extending after the sealing gasket detaches from the guide strip 133. Finally, the second telescopic device 131 and the third telescopic device 132 retract simultaneously, returning the positioning annular plate 135, the pushing annular plate 134, and each of the guide strips 133 to their initial state.

[0043] In another embodiment, such as Figure 6 As shown, the lubrication device 220 includes a first annular tube 222, an outer support frame 221, and a fourth telescopic device 224. The outer support frame 221 is fixedly disposed on the side of the first annular tube 222 away from the double-walled corrugated pipe. One end of the fourth telescopic device 224 is fixedly connected to the lower housing 200, and its movable end is fixedly connected to the outer support frame 221. The inner diameter of the first annular tube 222 is larger than the outer diameter of the double-walled corrugated pipe. A plurality of first nozzles 223 are spaced apart on the inner annular surface of the first annular tube 222. A first liquid inlet is provided on the first annular tube 222.

[0044] The first inlet on the first annular pipe 222 is used to connect to a pipe, which is connected to an external lubricant pumping device to deliver lubricant into the first annular pipe 222, and then sprayed out through each of the first nozzles 223. Preferably, the first inlet is located at the upper end of the first annular pipe 222 to facilitate the rapid filling of the first annular pipe 222 with lubricant. After the double-walled corrugated pipe enters the lower housing 200, the fourth telescopic device 224 extends to allow the first annular pipe 222 to be fitted onto the insertion end of the double-walled corrugated pipe. At the same time, lubricant is introduced into the first annular pipe 222 through the first inlet on the first annular pipe 222, and then sprayed onto the outer periphery of the insertion end of the double-walled corrugated pipe through each of the first nozzles 223. The outer support frame 221 is as follows: Figure 6 As shown, it can be configured as a gate-type bracket, which can provide sufficient support for the first annular tube 222 without affecting the first annular tube 222 being sleeved on the double-walled corrugated pipe.

[0045] In another embodiment, such as Figure 7 As shown, the socket lubrication device 230 includes a second annular tube 231, an inner support frame 233, and a fifth telescopic device 234; the inner support frame 233 is fixedly connected to the inner annular surface of the second annular tube 231; one end of the fifth telescopic device 234 is fixedly connected to the lower housing 200, and its movable end is fixedly connected to the inner support frame 233; the outer diameter of the second annular tube 231 is smaller than the inner diameter of the double-walled corrugated pipe, and a plurality of second nozzles 232 are spaced apart on the outer annular surface of the second annular tube 231, and a second liquid inlet is provided on the second annular tube 231.

[0046] The second inlet on the second annular pipe 231 is used to connect to a pipeline, which is connected to an external lubricant pumping device to deliver lubricant into the second annular pipe 231, and then spray it out through each of the second nozzles 232. Preferably, the second inlet is located at the upper end of the second annular pipe 231 to facilitate the rapid filling of the second annular pipe 231 with lubricant. After the double-walled corrugated pipe enters the lower housing 200, the fifth telescopic device 234 extends to allow the second annular pipe 231 to extend into the socket end of the double-walled corrugated pipe. At the same time, lubricant is introduced into the second annular pipe 231 through the second inlet on the second annular pipe 231, and then sprayed onto the inner wall of the socket end of the double-walled corrugated pipe through each of the second nozzles 232. The inner support frame 233 is as follows: Figure 7 As shown, it can be configured as a Y-shaped bracket, which ensures sufficient support for the second annular tube 231 while not affecting the extension of the second annular tube 231 into the double-walled corrugated tube.

[0047] Both the first annular pipe 222 and the second annular pipe 231 can be formed by bending and connecting ordinary pipes.

[0048] In another embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the clamping and feeding device 210 includes a screw 212 and a motor 211 that drives the screw 212. Multiple sliders 213 are sleeved on the screw 212, and the sliders 213 are threadedly connected to the screw 212. The sliders 213 on the screws 212 on both sides of the lower housing 200 are symmetrically arranged. A sixth telescopic device 214 is correspondingly provided at the bottom of each slider 213, with the movable end of the sixth telescopic device 214 facing the groove. A lower support rod 215 is hinged to the movable end of the sixth telescopic device 214. The lower support rod 215 is perpendicular to the sixth telescopic device, and a second tension spring 217 is provided between the lower support rod 215 and the movable end of the sixth telescopic device 214. A lower jaw 216 is fixedly connected to the end of the lower support rod 215 away from the sixth telescopic device 214, and the lower jaw 216 is arc-shaped to cooperate with the double-walled corrugated pipe.

[0049] Furthermore, when the sixth telescopic device 214 is in its shortest length state, the top surface of the lower support rod 215 is in contact with the bottom surface of the lower housing 200, and the lower claw 216 is located inside the lower housing 200.

[0050] Under no external force, the lower support rod 215 remains perpendicular to the movable end of the sixth telescopic device 214 under the action of the second tension spring 217, i.e., it remains horizontal. The sliders 213 on both sides are arranged in pairs, so the lower claws 216 on the corresponding two lower support rods 215 jointly clamp the double-walled corrugated pipe. First, the sixth telescopic device 214 is in its shortest length state. After the double-walled corrugated pipe completes the sealing gasket installation in the lower cavity, the first telescopic devices 122 on both sides are simultaneously contracted to release the double-walled corrugated pipe. The double-walled corrugated pipe will fall into each pair of lower claws 216 in the lower housing 200, where each pair of lower claws 216 clamps and fixes the double-walled corrugated pipe. After the inlet and outlet ends of the double-walled corrugated pipe are coated with lubricant, the sixth telescopic devices 214 on both sides are simultaneously extended, moving the double-walled corrugated pipe down into the groove, as... Figure 8As shown. Then, the motors 211 on both sides are started simultaneously, driving the corresponding screws 212 to rotate, thereby driving each slider 213 to move forward simultaneously, so as to move the double-walled corrugated pipe forward to dock with the double-walled corrugated pipe already installed in the groove. After docking, the sixth telescopic devices 214 on both sides are retracted at the same time. At this time, each lower support rod 215 will rotate downward around the hinge point of its movable end with the sixth telescopic device 214 due to the resistance of the double-walled corrugated pipe until it leaves the double-walled corrugated pipe, and then return to the horizontal state under the action of the second tension spring 217. Preferably, the lower claw 216 is correspondingly locked in the trough on the outer wall of the double-walled corrugated pipe to more stably clamp the double-arm corrugated pipe. In this invention, the first telescopic device 122, the second telescopic device 131, the third telescopic device 132, the fourth telescopic device 224, the fifth telescopic device 234 and the sixth telescopic device 214 can be selected from suitable pneumatic, electric or hydraulic telescopic cylinders according to the load and stroke requirements, and there is no limitation here.

[0051] In another embodiment, the guiding mechanism 110 includes two guide plates 111 symmetrically arranged on the inner wall of the upper housing 100 along the longitudinal axis of the upper housing 100. The guide plates 111 are hinged to the inner wall of the upper housing 100, and a telescopic rod 112 is provided between the bottom surface of the guide plate 111 and the inner wall of the upper housing 100. The two ends of the telescopic rod 112 are respectively hinged to the guide plate 111 and the inner wall of the upper housing 100. When the two guide plates 111 are in a horizontal state, the distance between them is less than the diameter of the double-walled corrugated pipe.

[0052] Within the upper housing 100, two guide plates 111 divide the interior of the upper housing 100 into an upper cavity and a lower cavity. The telescopic rod 112 is extended or retracted to adjust the angle between the guide plates 111 and the inner wall of the upper housing 100, thereby adjusting the distance between the two guide plates 111. (Refer to...) Figure 3 When the telescopic rods 112 on both sides retract simultaneously, the two guide plates 111 rotate downwards simultaneously, allowing the double-walled corrugated pipe located in the upper cavity to pass between them and enter the lower cavity. Then, the telescopic rods 112 on both sides extend simultaneously, so that the two guide plates return to horizontal, preventing the remaining double-walled corrugated pipe from continuing to enter the lower cavity.

[0053] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
