[0025] The following will disclose several embodiments of the present application with figures. For the purpose of clear illustration, many details of the embodiments will be described in the following description. However, it should be understood that these details of the embodiments should not be used to limit the present application. That is, in some embodiments of the present application, these details of the embodiments are not necessary. In addition, for the purpose of simplifying the figures, some conventional structures and components will be shown in a simple schematic manner in the figures.

[0026] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0027] Please refer to Figs. 1-3 When using simple tools for docking, it is usually only installed above the corrugated pipe, and the bottom lacks good support. Considering that the corrugated pipe is large in size, this insufficient support will increase the difficulty of docking, reduce convenience, and seriously affect the construction efficiency and quality. Based on this, the present application provides a corrugated pipe quick connecting device, which comprises a limiting part 1 for supporting, the limiting part 1 has two groups and is symmetrically arranged, and a connecting area 2 is arranged between the two groups of limiting parts 1 for docking the target object;

[0028] The limiting part 1 comprises a limiting ring 11, the limiting ring 11 is arranged in a preset angle and is fixed to the outside of the target object;

[0029] The two sides of the limiting ring 11 are provided with a driving part 3, and the driving part 3 is used to drive the two limiting rings 11 to approach each other.

[0030] The two groups of limiting parts 1 are symmetrically arranged and arranged in a preset angle. The bending angle can be set as an arc shape matched with the outer circumference of the corrugated pipe, so as to better fit the outside of the corrugated pipe. The limiting ring 11 is made of high-strength aluminum alloy material, which has the characteristics of light weight and high strength, and can not only facilitate installation but also ensure sufficient supporting force.

[0031] The limiting ring 11 is fixed to the outside of the target object (i.e. the corrugated pipe) by a special fixing method. A rubber non-slip pad can be provided inside the limiting ring 11 to increase the friction with the surface of the corrugated pipe. A plurality of mounting holes are provided on the limiting ring 11, and the limiting ring 11 is tightly fixed on the corrugated pipe by bolts passing through the mounting holes, ensuring that the limiting ring 11 will not shift during the connection process.

[0032] The connecting area 2 formed between the two sets of limiting parts 1 is the key space for docking the target object. In this subway drainage project, the bell and spigot of the two corrugated pipes are placed in this connecting area 2 for docking. Generally, the width is slightly larger than the pipe diameter of the corrugated pipe, and the height needs to be ensured to accommodate the connecting part of the bell and spigot.

[0033] The two sides of the limiting ring 11 are provided with driving parts 3, and each driving part 3 is connected with an independent control system, which can be operated by a remote controller. When it is necessary to drive the two limiting rings 11 to approach each other, the operator presses the corresponding button on the remote controller, and the driving part 3 starts to work, slowly pushing the limiting ring 11, so that the bell and spigot of the two corrugated pipes gradually approach until they are tightly docked.

[0034] In order to ensure the stability and synchronization of driving, a synchronous sensor is also provided on the driving part 3. The synchronous sensor can monitor the movement of the two driving parts 3 in real time and feed back the data to the control system. If the movement speed or position of the two driving parts 3 deviates, the control system will automatically adjust to ensure that the two limiting rings 11 can approach at the same time and synchronously, thereby ensuring the accurate docking of the corrugated pipes.

[0035] Operation process

[0036] First, install the two sets of limiting parts 1 on the outside of the two corrugated pipes to be connected, and fix the limiting ring 11 firmly by bolts and rubber non-slip pads.

[0037] Adjust the positions of the two corrugated pipes so that their bell and spigot are aligned with the connecting area 2.

[0038] The operator uses the remote controller to start the driving part 3 and push the two limiting rings 11 to approach each other. In this process, the synchronous sensor monitors the driving situation in real time to ensure that the limiting rings 11 move synchronously.

[0039] When the bell and spigot of the two corrugated pipes are tightly docked, turn off the driving part 3 and complete the connection operation.

[0040] The drive unit 3 can quickly drive the two limiting rings 11 to approach each other, realizing the rapid docking of the corrugated pipe. This avoids the tedious process of manually adjusting the socket in the traditional socket connection method, greatly shortens the connection time, and improves construction efficiency. The limiting rings 11 are bent at a preset angle and tightly fixed on the outside of the corrugated pipe, which can provide stable support and positioning for the corrugated pipe, ensure accurate alignment of the socket, reduce connection difficulties and sealing problems caused by alignment deviation, and improve the quality and reliability of the connection.

[0041] The device is relatively simple to operate. Only one operator needs to control the drive unit 3 via remote control to complete the connection operation. It does not require multiple workers to work together, which reduces labor costs and labor intensity. The preset angle of the limit ring 11 and the size of the through area 2 can be adjusted according to the corrugated pipes of different diameters. It has strong applicability and can meet the connection requirements of corrugated pipes of different specifications.

[0042] Positioning blocks 13 are fixed on both sides of the limiting ring 11, and a screw hole 14 is provided on the block body of the positioning block 13 from top to bottom.

[0043] There are two limit rings 11 in each group, and they are arranged symmetrically. The screw holes 14 between the two positioning blocks 13 correspond one-to-one, and screws 12 are inserted into them.

[0044] The threads inside the screw holes 14 between the two positioning blocks 13 have opposite directions, and the positioning blocks 13 are controlled to move relative to each other by the screw 12.

[0045] The positioning blocks 13 fixed on both sides of the limiting ring 11 are made of high-strength cast iron to ensure that they will not be damaged when subjected to large pressure. The positioning blocks 13 are designed in the shape of cuboids, and their surfaces are polished to be smooth and flat. The positioning blocks 13 and the limiting ring 11 are firmly connected by welding. The screw holes 14 on the positioning blocks 13 run from top to bottom to ensure that the screw 12 can be screwed in and out smoothly.

[0046] The screw 12 is made of high-quality alloy steel, possessing high strength and toughness. Each set of limiting rings 11 has two rings arranged symmetrically, with corresponding threaded holes 14 between the two positioning blocks 13. The length of the screw 12 is customized according to the distance between the two positioning blocks 13, ensuring it can completely pass through the threaded holes 14. The threads inside the threaded holes 14 between the two positioning blocks 13 rotate in opposite directions; this is a key design feature of the device. When the screw 12 is rotated, due to the opposite thread directions, the two positioning blocks 13 will move relative to each other under the action of the screw 12.

[0047] Operating procedures

[0048] First, install the two sets of limiting parts 1 on the outside of the two corrugated pipes to be connected to ensure that the limiting ring 11 fits tightly with the corrugated pipe.

[0049] Insert the screw rod 12 into the corresponding positioning block 13 screw hole 14, at this time the screw rod 12 is in the initial position, the distance between the two positioning blocks 13 is larger.

[0050] Use a wrench or other tool to rotate the screw rod 12, as the two positioning block 13 screw hole 14 thread direction is opposite, with the rotation of the screw rod 12, the two positioning blocks 13 will gradually close. In this process, the limiting ring 11 will also move, leading to the gradual alignment of the two bell and spigot.

[0051] Continue to rotate the screw rod 12 until the two bell and spigot are tightly connected and the required connection tightness is achieved.

[0052] Finally, check the connection to ensure that the connection is firm and reliable.

[0053] By rotating the screw rod 12, the relative movement of the two positioning blocks 13 can be achieved, thereby moving the limiting ring 11 to complete the connection of the corrugated pipe. Compared with the traditional bell and spigot connection method of multiple people working together, this operation method is more convenient and can be completed by a single person, greatly improving the connection efficiency and saving construction time. The positioning block 13 and the screw rod 12 are designed to cooperate, so that the corrugated pipe can be accurately aligned during connection. Since the rotation of the screw rod 12 is controllable, the operator can accurately control the relative movement distance of the two positioning blocks 13 according to the actual needs, thereby ensuring the accuracy of the bell and spigot connection of the corrugated pipe and improving the connection quality.

[0054] The positioning block 13 is firmly connected with the limiting ring 11, and the screw rod 12 is tightly matched with the screw hole 14. This structure design makes the entire connection device provide stable support force during connection, ensuring that the corrugated pipe does not shift or shake during connection, and ensuring the stability and reliability of the connection. The device can be adapted to the connection needs of corrugated pipes of different diameters by replacing screw rods 12 of different specifications and adjusting the installation position of the positioning block 13. This makes the device have strong versatility and can be widely used in various drainage projects, reducing engineering costs.

[0055] The driving part 3 includes a sleeve 31, and the inner side of the sleeve 31 is provided with a telescopic piece, one end of the telescopic piece is provided with a shaft 33.

[0056] The telescopic piece controls the shaft 33 to make reciprocating motion along the horizontal center axis.

[0057] One end of the shaft 33 is provided with a sleeve ring 32, and the middle part of the sleeve ring 32 is provided with a through hole matched with the screw rod 12.

[0058] The sleeve 32 is installed between the two positioning blocks 13 and is sleeved with the screw rod 12. The control shaft 33 drives the sleeve 32 to drive the two target objects to move close to or away from each other along the horizontal central axis.

[0059] The sleeve 31 is made of high-strength stainless steel material, and the inner wall thereof is finely polished to reduce the friction with the telescopic part. The length and diameter of the sleeve 31 are designed according to the actual application scene and the required telescopic stroke. The telescopic part is selected as an electric push rod which has precise stroke control and large thrust output capacity. The electric push rod converts electric energy into mechanical energy of linear motion through the built-in motor and transmission mechanism. One end of the telescopic part is connected with the inner wall of the sleeve 31 through a special sliding guide rail, so as to ensure that the telescopic part can stably move linearly in the sleeve 31.

[0060] One end of the shaft 33 is connected with the telescopic part through a shaft coupling, so as to ensure that the power transmission between the shaft 33 and the telescopic part is stable and reliable.

[0061] The sleeve 32 is made of high-strength plastic. The through hole formed in the middle of the sleeve 32 is accurately matched with the size of the screw rod 12. A smooth wear-resistant coating is arranged on the inner wall of the through hole, so as to reduce the friction with the screw rod 12. The outer diameter of the sleeve 32 is slightly smaller than the spacing between the two positioning blocks 13, so as to ensure that the sleeve 32 can freely slide between the two positioning blocks 13.

[0062] Operation process

[0063] Two sets of limiting parts 1 are respectively installed outside the two corrugated pipes to be connected, and the screw rod 12 is inserted into the corresponding screw hole 14 of the positioning block 13.

[0064] The sleeve 32 is installed on the screw rod 12, and the sleeve 32 is ensured to be located between the two positioning blocks 13. The sleeve 31 of the driving part 3 is fixed at a suitable position, so that the movement direction of the telescopic part is consistent with the direction of the shaft 33 of the screw rod 12.

[0065] The telescopic part is started, and the telescopic part starts to work. The control shaft 33 moves along the horizontal central axis in a reciprocating manner. When the shaft 33 is pushed forward, the sleeve 32 moves forward along the screw rod 12. Since the sleeve 32 is sleeved with the screw rod 12, and the thread directions on the inner sides of the screw holes 14 between the two positioning blocks 13 are opposite, the movement of the sleeve 32 drives the two positioning blocks 13 to move relatively, so that the bell and spigot joints of the two corrugated pipes gradually approach each other. When the telescopic part reaches the maximum stroke, the bell and spigot joints of the two corrugated pipes are tightly connected.

[0066] If it is necessary to disassemble or adjust the connection of the corrugated pipes, it is only necessary to control the telescopic part to move in the opposite direction, so that the shaft 33 drives the sleeve 32 to move backward, and the two positioning blocks 13 move in opposite directions, so that the two corrugated pipes gradually separate.

[0067] The telescopic part of the driving part 3 can automatically control the movement of the shaft 33 and the collar 32, realize the quick connection and separation of the corrugated pipe, and reduce the complexity and labor intensity of manual operation. The operator only needs to start the telescopic part to complete the connection process, which greatly improves the construction efficiency.

[0068] The telescopic part can accurately control the movement stroke of the shaft 33, thereby accurately control the movement distance of the collar 32, and further accurately control the relative movement of the two positioning blocks 13. This makes the bell and spigot of the corrugated pipe accurately aligned and tightly butt-jointed, improves the connection precision and quality, and reduces the problems such as water leakage caused by loose connection.

[0069] The driving part 3 can adapt to corrugated pipes with different pipe diameters and different connection requirements by adjusting the stroke and thrust of the telescopic part. Whether it is a small drainage corrugated pipe or a large bridge drainage corrugated pipe, the device can be used for quick connection, and has strong universality.

[0070] Since most of the operations are automatically completed by the driving part 3, the opportunities for manual direct contact with the corrugated pipe and the screw rod 12 are reduced, the risk of injury to the operator during the connection process is reduced, and the safety of construction is improved.
