Description

Technical Field

[0001] This utility model relates to the field of concrete engineering machinery technology, and in particular to the field of automatic concrete pipe insertion and extraction equipment technology, specifically referring to an air-leakage-proof pipe insertion and extraction equipment interface and pipe insertion and extraction equipment. Background Technology

[0002] With the launch of subway projects across the country and the continuous promotion and application of tunnel segment production lines, the demand for tunnel segments is increasing, placing higher demands on their production scale and efficiency. Due to the large size of tunnel segments, they are mostly manufactured using prefabrication methods. As the main assembly component in tunnel boring machine (TBM) construction, the quality of tunnel segments directly affects the overall quality and safety of the construction project. The vibration compaction process of prefabricated tunnel segments is a key technology in TBM production, affecting the density, durability, and strength of the segment concrete.

[0003] Attached vibration is one of the main vibration methods currently used, which uses compressed air to drive a vibrator to complete the vibration work. This method requires manual connection of the vibration air pipes, which is labor-intensive and inefficient. Furthermore, due to the poor sealing at the air pipe interfaces, air leakage occurs, reducing the amount of air entering the vibrator within the mold and causing uneven vibration of the precast components. Insufficient vibration of the tunnel segments severely affects the vibration quality, preventing timely removal of air from the precast components and resulting in numerous air bubbles. This seriously affects the compactness, durability, and strength of the tunnel segments. The presence of air bubbles within the segments can easily lead to breakage during later use, affecting project quality and safety.

[0004] Therefore, there is a need for an air-leak-proof pipe-connecting device that can automatically connect compressed air pipelines to replace manual labor, reduce the labor intensity of workers, streamline the number of workers required for the production line, and at the same time, minimize air leakage at the interface, ensure sufficient vibration of components, and guarantee the production quality of precast components. Summary of the Invention

[0005] The main purpose of this utility model is to provide an air-leakage-proof tube insertion and removal device interface and tube insertion and removal device, so as to solve the problems of high labor intensity and low production efficiency in the vibration process of precast shield tunnel segments in the prior art, which relies on manual connection of vibration air pipes, and the problem that the air pipe interface is not sealed tightly, resulting in a reduction in the amount of air entering the vibrator in the mold, insufficient vibration, and inability to guarantee the production quality of shield tunnel segments.

[0006] To achieve the above objectives, this utility model provides a leak-proof plug-in / plug device interface, including an equipment end interface flange, an equipment end air supply pipe, a mold end interface flange, and a mold end air supply pipe. The equipment end interface flange is located at one side port of the equipment end air supply pipe, and the mold end interface flange is located at one side port of the mold end air supply pipe. The equipment end interface flange and the mold end interface flange are connected by a tenon and mortise structure. The equipment end interface flange has a protruding tenon, and the mold end interface flange has a mortise groove that matches the tenon. A groove is provided on the end face of the equipment end interface flange and the mold end interface flange that contact each other, and a sealing ring is provided in the groove.

[0007] Furthermore, the groove is an annular groove, and an inwardly extending anti-detachment eave is provided on the outer side of the groove.

[0008] Furthermore, the sealing ring is fully embedded in the groove, and the height of the sealing ring is higher than the edge height of the groove.

[0009] Furthermore, the sealing ring is made of polyurethane or rubber material through a thermoplastic process.

[0010] Furthermore, a through hole is provided in the middle of the equipment end interface flange and the mold end interface flange, and the port of the gas transmission pipe is sleeved in the through hole.

[0011] Furthermore, a first fixing flange is provided on the back of the equipment end interface flange. The first fixing flange is sleeved on the equipment end gas supply pipe and connected to the equipment end interface flange by bolts to fix the equipment end interface flange.

[0012] Furthermore, a second fixed flange is fitted onto the gas supply pipe at the mold end, and a protective sleeve is fitted onto the gas supply pipe at the mold end between the second fixed flange and the mold end interface flange. The second fixed flange and the protective sleeve are connected by bolts.

[0013] To achieve the above objectives, this utility model also provides a leak-proof tube removal device, including a head and a support set at the bottom of the head. Using the leak-proof tube removal device interface, the air supply pipe at the device end of the leak-proof tube removal device interface is set in a Z-shape on the inside of the head.

[0014] Furthermore, a fixing device is provided at the connection between the head and the air supply pipe at the equipment end. The fixing device is sleeved on the air supply pipe at the equipment end and includes a support frame and several tension springs. The tension springs are evenly arranged between the support frame and the air supply pipe at the equipment end along the circumference of the air supply pipe at the equipment end.

[0016] This utility model features an air-leakage prevention structure at the interface of the tube insertion and removal equipment.

[0027] Example 1

[0028] like Figure 1 The diagram illustrates a leak-proof connector for a plug-in device, comprising an equipment-end flange 1, an equipment-end air supply pipe 2, a mold-end flange 3, and a mold-end air supply pipe 4. The equipment-end flange 1 is located at one end of the equipment-end air supply pipe 2, and the mold-end flange 3 is located at one end of the mold-end air supply pipe 4. The equipment-end flange 1 and the mold-end flange 3 are connected by a tenon-and-groove structure. The equipment-end flange 1 has a protruding tenon 10, and the mold-end flange 3 has a mortise 30 that matches the tenon 10. A groove 11 is provided on the end face of the equipment-end flange 1 and the mold-end flange 3 where they contact each other, and a sealing ring 12 is placed within the groove 11. The groove 11 and the sealing ring 12 together constitute a leak-proof structure, which is located on the end face of the equipment-end flange 1.

[0029] Specifically, the groove 11 is an annular groove 11, and an inwardly extending anti-detachment eave 111 is provided on the outer side of the groove 11, such as... Figure 2 The cross-section of the groove 11 shown is stepped, and the sealing ring 12 is prevented from falling out of the groove 11 by the obstruction of the anti-detachment eaves 111.

[0030] Specifically, such as Figure 2 As shown, the sealing ring 12 is entirely embedded in the groove 11. The height h of the sealing ring 12 is higher than the edge height H of the groove 11, which is equivalent to the sealing ring 12 having a protrusion relative to the end face. The cross-section of the sealing ring 12 is stepped. After the interface connection is completed, the equipment end interface flange 1 and the mold end interface flange 3 are pressed against each other, and the sealing ring 12 is in a compressed state, making tight contact with the equipment end interface flange 1 and the mold end interface flange 3 respectively, ensuring the airtightness of the interface.

[0031] Specifically, the sealing ring 12 is made of polyurethane or rubber material through a thermoplastic process.

[0032] Specifically, a through hole is provided at the middle position of the equipment-end interface flange 1 and the mold-end interface flange 3, and the port of the gas supply pipe is sleeved in the through hole. The gas supply pipe is tightly connected to the interface flange.

[0033] Specifically, a first fixed flange 21 is provided on the back of the equipment end interface flange 1. The first fixed flange 21 is sleeved on the equipment end gas supply pipe 2 and connected to the equipment end interface flange 1 by bolts, for fixing the equipment end interface flange 1.

[0034] Specifically, a second fixed flange 41 is fitted onto the gas supply pipe 4 at the mold end, and a protective sleeve 43 is fitted onto the gas supply pipe 4 at the mold end between the second fixed flange 41 and the mold end interface flange 3. The second fixed flange 41 and the protective sleeve 43 are connected by bolts.

[0035] Example 2

[0036] like Figure 3 and Figure 4 The device shown includes a head 5 and a support 6 located at the bottom of the head 5. The device uses an air-proof insertion and removal device interface. The device end air supply pipe 2 of the air-proof insertion and removal device interface is arranged in a Z-shape on the inside of the head 5 and passes through the head 5 of the insertion and removal device.

[0037] Specifically, such as Figure 4 As shown, a fixing device is provided at the connection between the head 5 and the equipment end air supply pipe 2. The fixing device is sleeved on the equipment end air supply pipe 2 and includes a support frame 51 and several tension springs 52. The tension springs 52 are evenly arranged between the support frame 51 and the equipment end air supply pipe 2 along the circumference of the equipment end air supply pipe 2. The position of the equipment end air supply pipe 2 is adjusted by the tension springs 52, thereby adjusting the position of the equipment end interface flange 1, so that the tenon 10 of the equipment end interface flange 1 and the tenon 30 of the mold end interface flange 3 can be interlocked, ensuring a tight connection at the interface.

[0038] Example 3

[0039] As a further improvement to Embodiment 2, in practical applications, the device can be equipped with multiple leak-proof insertion / removal interfaces arranged side-by-side on a single insertion / removal device, according to actual needs, thus functioning as a multi-interface insertion / removal device. For example... Figure 5 The 3-port insertion and removal device shown has 3 air-proof insertion and removal interfaces arranged side by side on one device. It can be used to connect the three vibration air inlets of the mold at the same time, and input gas at the same time to complete the vibration process, so that the vibration is more thorough.

[0040] The specific working state of the tube extraction and insertion device provided by this utility model is as follows: The device end interface flange 1 is installed to the port of the device end air supply pipe 2 using bolts. The mold end interface flange 3 is installed onto the mold end air supply pipe 4. The device is then installed on the vibration station. When the mold moves to the vibration station, the tube extraction and insertion device can autonomously identify the mold model and adjust the position of the device end air supply pipe 2 via the tension spring 52, thereby adjusting the position of the device end interface flange 1 so that the device end interface flange 1 and the mold end interface flange 3 can fit tightly together. After the position adjustment is completed, the cylinder drives the device end air supply pipe 2 to extend towards the mold. The device end interface flange 1 and the mold end interface flange 3 are connected by a tenon and mortise structure. The mold end interface flange 3 and the device end interface flange 1 fit tightly together and press against each other, compressing the sealing ring 12 to ensure the airtightness of the interface. After the interface connection is completed, the compressed gas is released by electrical control. After vibration for a period of time, the compressed gas supply is stopped, and the device end air supply pipe 2 is retracted by the cylinder, completing the vibration process.

[0041] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
