Description
Technical Field
[0001] The utility model relates to the technical field of steel corrugated pipe culvert connection, in particular to a flange socket type steel corrugated pipe culvert. Background Art
[0002] Stainless steel bellows are installed in liquid transportation systems as a flexible pressure-resistant pipe fitting to compensate for the mutual displacement of the connection ends of pipelines, machines, and equipment, absorb vibration energy, and play a role in vibration reduction and noise reduction. They have many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance. However, due to the different distances of liquid transportation, in actual use, it is necessary to connect the two ends of multiple bellows according to the distance the liquid needs to be transmitted.
[0003] At present, when installing the corrugated pipe, it is necessary to first place a laying frame for supporting the corrugated pipe on the ground at the laying position of the corrugated pipe, and then place the corrugated pipe on the top of the laying frame. Under the action of the laying frame, the middle parts of the open ends of the two adjacent corrugated pipes can be on the same horizontal line, and then adjust the position of one of the corrugated pipes until it fits with the open end of the other corrugated pipe. At the same time, the flanges at one end of the two corrugated pipes fit together, and then insert one end of the bolt from the through hole opened on the outside of one of the flanges into the through hole opened on the outside of the other flange until the bolts are inserted into the through holes distributed in a ring, and then install the nut to the outside of the bolt, and then use a fixing tool to rotate the nut and fix the bolt at the same time until the nut no longer rotates, so that the two adjacent corrugated pipes can be fixed through the flange.
[0004] Although the above method can connect and fix two adjacent corrugated pipes, due to the circular structure of the flange, the height of the through holes opened on the outside of the flange is different from the ground. When fixing the corrugated pipe, the construction workers need to change their posture according to the position of the through holes (sometimes they need to bend over, lie on their backs, squat, etc.) and continuously assemble bolts and nuts at different positions, thereby increasing the difficulty of fixing two adjacent corrugated pipes through the flange as well as the time and effort required. Utility Model Content

When fixing the corrugated pipe, the construction workers need to change their posture according to the position of the through holes (sometimes they need to bend over, lie on their backs, squat, etc.) and continuously assemble bolts and nuts in different positions, thereby increasing the difficulty of fixing two adjacent corrugated pipes through the flange as well as the time and energy required.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solution: a flange socket type steel corrugated pipe culvert, comprising:
[0007] Corrugated tubes that plug into each other.
[0008] Mounting rings are fixedly installed on both ends of the bellows.
[0009] The connecting component is rotatably mounted at the connection of two plug-in bellows and is used to connect two adjacent bellows. The connecting component can be rotated at the plug-in connection of the bellows with the axis of the bellows as the rotation axis to adjust the position of the connecting component.
[0010] As a further description of the above technical solution:
[0011] The connecting component includes.
[0012] The two fixing rings are respectively rotatably mounted on the mounting rings at both ends of the bellows.
[0013] The mounting holes are arranged on the fixing ring, and bolts are inserted into the mounting holes at the plug-in places of the two bellows for fixing the plug-in places of the bellows.
[0014] As a further description of the above technical solution:
[0015] The mounting ring is provided with a mounting groove for mounting a fixing ring, and the fixing ring can rotate in the mounting groove.
[0016] As a further description of the above technical solution:
[0017] There are multiple mounting holes, which are evenly arranged in an annular shape on the outer wall of the fixing ring.
[0018] As a further description of the above technical solution:
[0019] A plurality of mutually plugged connecting rings are also provided between the mutually plugged corrugated pipes, and the connecting rings can extend the end positions of the corrugated pipes.
[0020] As a further description of the above technical solution:

[0024] The utility model has the following beneficial effects:
[0025] In the present invention, when it is necessary to insert bolts into the remaining mounting holes, the fixing ring 1 is rotated. Since one bolt has been used to connect the fixing ring 1 and the fixing ring 2, the fixing ring 2 can be rotated synchronously with the fixing ring 1 until the mounting holes without bolts are rotated to be directly above the bellows 1 and the bellows 2. In this way, the mounting holes without bolts can be adjusted one by one to be directly above the bellows 1 and the bellows 2, and bolts can be inserted one by one into the inside of the bellows 1 and the bellows 2 and connected using nuts. This allows construction workers to always maintain the same posture to install multiple bolts and nuts, reducing the difficulty of connecting the bellows 1 and the bellows 2 and the time and effort required.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1-3 The utility model provides an embodiment of a flanged and socket-type steel bellows culvert, comprising:
[0033] Multiple bellows 1 and bellows 2 2 are arranged alternately and plugged into each other. By continuously staggering the installation of bellows 1 and bellows 2 2, the liquid transmission distance can be increased. At the same time, the bellows 1 and bellows 2 2 have the same shape and diameter, which is conducive to the docking and installation between the bellows 1 and bellows 2 2. At the joint of the two bellows, the outer diameter of the plug-in interface of the bellows 2 2 and the bellows 1 is the same as the inner diameter of the bellows 1, so that the bellows 1 and the bellows 2 2 can be plugged into each other.
[0034] There are two mounting rings 3 fixedly sleeved on the outer wall of the bellows 1, and two mounting rings 10 fixedly sleeved on the outer wall of the bellows 2. The mounting rings 3 and 10 serve as mounting rings for the bellows, and are used to achieve the connection and fixation between the two plug-in bellows. The specific setting method is as follows:
[0035] The end of the mounting ring 13 close to the open end of the bellows 1 is flush with the open end of the bellows 1. Similarly, the end of the mounting ring 2 10 close to the open end of the bellows 2 2 is flush with the open end of the bellows 2 2, thereby achieving that when the bellows 1 and the bellows 2 are close to each other, one end of the mounting ring 13 can fit with one end of the mounting ring 2 10.
[0036] An annular groove 1 is provided on the outer wall of the mounting ring 1 3, and a fixing ring 4 is rotatably installed in the inner cavity of the annular groove 1. The fixing ring 1 4 can freely rotate on the outer wall of the mounting ring 1 3 through the annular groove 1. An annular groove 2 is provided on the outer wall of the mounting ring 2 10, and a fixing ring 2 8 is rotatably installed in the inner cavity of the annular groove 2. The fixing ring 2 8 can freely rotate on the outer wall of the mounting ring 2 10 through the annular groove 2.
[0037] Multiple mounting holes are provided on the outer walls of the fixing ring 1 4 and the fixing ring 2 8. The multiple mounting holes are evenly distributed in a circular shape on the outer walls of the fixing ring 1 4 and the fixing ring 2 8. By providing multiple mounting holes on the outside of the fixing ring 1 4 and the fixing ring 2 8, the bellows 1 and the bellows 2 2 can be connected by multiple sets of bolts, which is beneficial to improving the firmness of the connection between the bellows 1 and the bellows 2 2.
[0038] After the mounting ring 1 3 and one end of the mounting ring 2 10 are fitted together, manually rotate the fixing ring 1 4 and the fixing ring 2 8 until one of the mounting holes on the outer wall of the fixing ring 1 4 is rotated to the top of the bellows 1 1, and one of the mounting holes on the outer wall of the fixing ring 2 8 is rotated to the top of the bellows 2 2, align the mounting hole located just above the bellows 1 1 with the mounting hole located just above the bellows 2 2, and then insert the small end of the bolt into the mounting hole just above the bellows 1. The bolts are continuously inserted into and penetrate the inner cavity of the mounting hole located directly above the bellows 2 until the large head end of the bolt fits against the outer wall of the fixing ring 4, and then the small head end of the bolt is installed with a nut, and the nut is continuously rotated by a tool. With the cooperation of the thread, the nut continuously approaches the fixing ring 2 8 until one end of the nut fits against the outer wall of the fixing ring 2 8. Only under the continuous pressure of the large head end of the bolt and the nut on the fixing ring 4 and the fixing ring 2 8, the connection between the bellows 1 and the bellows 2 2 can be achieved.
[0039] In this embodiment, the shape and size of the fixing ring 1 4 and the fixing ring 2 8 are the same, and the mounting holes opened on the outer walls of the fixing ring 1 4 and the fixing ring 2 8 are in the same position. After the mounting hole located directly above the bellows 1 and the mounting hole located directly above the bellows 2 2 are aligned, the remaining mounting holes on the outer wall of the fixing ring 1 4 and the remaining mounting holes on the outer wall of the fixing ring 2 8 are all in an aligned state.
[0040] The fixing ring 1 4, the fixing ring 2 10 and the bolts constitute a connecting assembly of two bellows (i.e., bellows 1 1 and bellows 2 2). The connecting assembly can adjust the positions of the threaded holes on the fixing ring 1 4 and the fixing ring 2 10. When the bellows 1 1 and the bellows 2 2 need to be connected, first move the bellows 1 or the bellows 2 2 until the mounting ring 1 3 at one end of the bellows 1 and one end of the mounting ring 2 10 at one end of the bellows 2 2 fit together.
[0041] When it is necessary to insert bolts into the remaining mounting holes, rotate the fixing ring 1 4. Since one bolt has been used to connect the fixing ring 1 4 and the fixing ring 2 8, the fixing ring 2 8 can be rotated synchronously with the fixing ring 1 4 until the mounting holes without bolts are rotated to directly above the bellows 1 1 and the bellows 2 2. In this way, the mounting holes without bolts can be adjusted one by one to directly above the bellows 1 1 and the bellows 2 2, and bolts can be inserted into them one by one and connected using nuts. This allows construction workers to maintain the same posture while installing multiple bolts and nuts, reducing the difficulty, time and effort required for the connection between the bellows 1 and the bellows 2 2.
[0042] Example 2
[0043] The connection method of Example 1 is only suitable for the construction method of laying corrugated pipes from one end in sequence. However, when laying the corrugated pipes, in order to save the construction period required for laying the corrugated pipes and increase the laying rate, the two ends of the laying section will generally be moved closer to the middle section of the laying, so as to achieve the purpose of saving laying time. When laying the corrugated pipes from the two ends to the middle, it is often necessary to cut one end of the corrugated pipe due to the long length of the corrugated pipe, so that one end of the two corrugated pipes located in the middle of the laying section can be smoothly fitted and connected. However, due to certain errors in the cutting and laying of the corrugated pipes, the two corrugated pipes located at the connection in the middle of the laying section cannot be tightly connected, which makes it easy for leakage to occur during liquid transmission.
[0044] In this embodiment, a connecting ring 1 is fixedly installed on one end of the mounting ring 3 close to the mounting ring 2 10, and a connecting ring 2 6 is detachably installed on the end of the connecting ring 1 away from the mounting ring 3, and a plurality of plug-in columns 5 are fixedly installed in a ring-shaped distribution on the end of the connecting ring 1 away from the mounting ring 3, and a plurality of plug-in holes compatible with the plug-in columns 1 5 are opened in a ring-shaped distribution on the end of the connecting ring 2 6 close to the connecting ring 1. Before the bellows 1 and the bellows 2 2 are connected, the connecting ring 2 6 is placed between the bellows 1 and the bellows 2 2, and then the plurality of plug-in columns 5 distributed in a ring are inserted into the plurality of plug-in holes distributed in a ring, until one end of the plug-in column 5 is in contact with the inner wall of the plug-in hole away from its own open end, and one end of the connecting ring 2 6 is tightly fitted with one end of the connecting ring 1.
[0045] The end of the connecting ring 2 6 away from the connecting ring 1 is detachably installed with the connecting ring 3 11, and the end of the connecting ring 2 6 away from the sealing ring 1 13 is fixedly installed with the plug-in column 2 12. The end of the connecting ring 3 11 close to the connecting ring 2 6 is provided with a mounting hole. When the connecting ring 3 11 is placed between the connecting ring 2 6 and the bellows 2 2, the connecting ring 3 11 is allowed to move closer to the connecting ring 2 6 until multiple plug-in columns 2 12 are inserted into multiple mounting holes at the same time.
[0046] The plug-in column 1 5 serves as a plug-in column between the installation ring and the connecting ring, and the plug-in column 2 12 serves as a plug-in column of the adjacent connecting ring, thereby enabling installation between the installation ring and the connecting ring.
[0047] A connecting ring four 9 movably connected to the connecting ring three 11 is fixedly installed on one end of the mounting ring two 10 close to the mounting ring one 3. After the connecting ring one and the connecting ring two 6 are connected, the connecting ring three 11 is installed between the connecting ring two 6 and the bellows two 2 until one end of the connecting ring three 11 is fitted with the other end of the connecting ring two 6. At the same time, the bellows two 2 is moved so that one end of the connecting ring four 9 is tightly fitted with the other end of the connecting ring three 11.
[0048] A sealing ring 13 is fixedly installed on the end of the connecting ring 2 6 close to the connecting ring 1, and an annular sealing groove 1 that is compatible with the sealing ring 13 is fixedly installed on the end of the connecting ring 1 away from the mounting ring 3. When one end of the connecting column 1 5 is in contact with the inner wall of the plug-in hole away from its own open end, the end of the sealing ring 13 away from the connecting ring 2 6 is inserted into the interior of the annular sealing groove 1 and in contact with the inner wall of the annular sealing groove 1 away from its own open end, thereby increasing the sealing between the connecting ring 2 6 and the connecting ring 1, and avoiding leakage when the liquid passes between the connecting ring 2 6 and the connecting ring 1.
[0049] Sealing rings 2 7 are fixedly installed at both ends of connecting ring 3 11, and annular sealing grooves 2 that are compatible with sealing ring 2 7 are provided at one end of connecting ring 2 6 close to connecting ring 3 11 and one end of connecting ring 4 9 away from mounting ring 2 10. When one end of connecting ring 3 11 is tightly fitted with one end of connecting ring 2 6, one of sealing rings 2 7 is inserted into the inside of the annular sealing groove 2 opened at one end of connecting ring 2 6, and then bellows 2 2 is moved to allow the other sealing ring 2 7 to be inserted into the inside of the annular sealing groove 2 opened at one end of connecting ring 4 9, until one end of the two sealing rings 2 7 is fitted with the inner walls of the two annular sealing grooves 2 away from the open ends, which is beneficial to increase the sealing between connecting ring 3 11 and connecting ring 2 6 as well as connecting ring 4 9.
[0050] Due to the uncertain length of the laying section, when the two adjacent corrugated pipes (corrugated pipe 1 and corrugated pipe 2 2) located in the middle of the laying section cannot be plugged in, the connecting rings (including connecting ring 1, connecting ring 2 2, connecting ring 3 11 and connecting ring 4 9 connected to one end of the two adjacent corrugated pipes) are placed between the two adjacent corrugated pipes (corrugated pipe 1 and corrugated pipe 2 2) and assembled, so as to compensate between the two adjacent corrugated pipes (corrugated pipe 1 and corrugated pipe 2 2) and allow bellows 1 1 and bellows 2 2 to be smoothly connected.
[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
