Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine slurry pipeline technology, and more specifically, to a tooling for quick-connect fitting. Background Technology

[0002] Miniature slurry balance tunnel boring machines (TBMs) are key equipment in the construction of urban underground pipe networks and various underground engineering projects. A large and complex slurry transport pipeline system is installed on the supporting trolley behind it—this system consists of dozens, even hundreds, of heavy-duty slurry hoses and metal joints connected in series with quick-connect clamps, running through the entire trolley structure. Due to long-term operation under harsh conditions of high pressure, high wear, and strong corrosion, the sealing reliability and structural stability of the pipeline connections directly affect the overall operational safety and construction efficiency of the machine.

[0003] However, current methods for connecting slurry pipes on the rear-mounted tunnel boring machine (TBM) still largely rely on manual hammering or general hand tools to crimp heavy hoses and connectors. This method is not only inefficient and extremely labor-intensive, but also lacks precise alignment and uniform pressure application, making it difficult to guarantee consistent crimping quality and greatly increasing the risk of high-pressure slurry leaks. Such problems severely restrict the continuity and progress of tunnel boring machine (TBM) construction, and may also disturb the strata, damage the tunnel face stability, and even pose a significant threat to the safety of on-site personnel. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a tooling for quick crimping of connectors to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A tooling for quick-connect fittings includes a tooling frame, a lower limit plate installed inside the tooling frame, an upper limit plate above the lower limit plate, the upper limit plate being connected to the output end of a first hydraulic telescopic rod, an installation groove connected to one side of the tooling frame, a sliding frame installed inside the installation groove, a slider slidably connected inside the sliding frame, and the top of the sliding frame being connected to an arc-shaped bracket via a second hydraulic telescopic rod.

[0007] Furthermore, the arc-shaped bracket is matched with the mud suction hose, and grooved pipe fittings are inserted at both ends of the mud suction hose. The mud suction hose and the grooved pipe fitting bracket are fixed together by safety clamps.

[0008] Furthermore, the lower limit plate is matched with the safety clamp.

[0009] Furthermore, a baffle is connected to the top of the lower limit plate.

[0010] Furthermore, a support frame is fixed at the top of the tooling frame, and the support frame is connected to the first hydraulic telescopic rod. The output end of the first hydraulic telescopic rod is connected through to one end of the tooling frame.

[0011] Furthermore, a straightening channel steel is connected to one side of the tooling frame, and one end of the straightening channel steel abuts against the grooved pipe joint.

[0012] Furthermore, limit frames are connected to both sides of the slider, and the top of the limit frame is provided with a threaded hole. A bolt is threaded inside the threaded hole, and one end of the bolt abuts against the slider.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting a lower limit plate and a straightening channel steel, the straightening channel steel can abut against the end face of the grooved pipe joint. With the lower limit plate and the baffle plate, the positioning constraint of the safety clamp is ensured, and the hose, the joint and the clamp are coaxially aligned. Then, the upper limit plate is driven by the first hydraulic telescopic rod to apply a stable and controllable clamping force to the safety clamp, which replaces the traditional manual knocking method, greatly shortens the single crimping time, improves the work efficiency, and ensures the consistency and reliability of the crimping quality.

[0015] (2) By setting an arc-shaped bracket that matches the outer contour of the slurry suction hose, and driving its lifting and lowering by a second hydraulic telescopic rod, the hose tail end can be stably and reliably automatically lifted. During the crimping operation, this structure can effectively overcome the sagging deformation caused by the weight of the heavy hose, keeping it in an ideal horizontal position, thereby ensuring that the hose axis is accurately aligned with the grooved pipe joint, avoiding problems such as uneven clamp crimping and sealing failure due to skew or bending. Furthermore, by setting a slider and sliding frame, the operator can manually or assistedly push the slider along the direction of the installation groove to quickly adjust the lateral position of the arc-shaped bracket according to the different lengths and specifications of the slurry suction hose, so that it accurately corresponds to the center of gravity of the hose.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a tooling for quick crimping of connectors is provided.

[0026] Example 1

[0027] like Figures 1-5As shown, the tooling for the quick-connect crimping fitting according to an embodiment of the present invention includes a tooling frame 1. A lower limit plate 2 is installed inside the tooling frame 1. A baffle 13 is connected to the top of the lower limit plate 2 to axially limit the safety clamp 12 and the grooved pipe fitting 11, preventing them from moving or shifting during the crimping process and ensuring the accuracy of the assembly position. An upper limit plate 3 is provided above the lower limit plate 2 and is connected to the output end of the first hydraulic telescopic rod 4. A support frame 14 is fixed to the top of the tooling frame 1. The support frame 14 is connected to the output end of the first hydraulic telescopic rod 4. The first hydraulic telescopic rod 4 is connected to the first hydraulic telescopic rod 4. The output end of the first hydraulic telescopic rod 4 is connected through to one end of the tooling frame 1. During the crimping operation, the first hydraulic telescopic rod 4 applies a controllable and uniform downward pressure, so that the upper limit plate 3 and the lower limit plate 2 work together to precisely compress the safety clamp 12 located between the two to the design position, thereby achieving a reliable locking and sealing of the hose and the joint. A straightening channel steel 15 is connected to one side of the tooling frame 1. One end of the straightening channel steel 15 abuts against the grooved pipe joint 11, which is used to guide and correct the hose during the initial positioning.

[0028] like Figures 1-3 As shown, a mounting groove 5 is connected to one side of the tooling frame 1. A sliding frame 6 is installed inside the mounting groove 5, and a slider 7 is slidably connected inside the sliding frame 6. The slider 7 can move flexibly along the length of the mounting groove 5 to adapt to the support requirements of hoses of different lengths. The top of the sliding frame 6 is connected to an arc-shaped bracket 9 via a second hydraulic telescopic rod 8. The shape of the arc-shaped bracket 9 matches the shape of the slurry suction hose 10. The arc-shaped bracket 9 has an anti-slip pad inside to further enhance friction and prevent the hose from accidentally slipping during lifting. Grooved pipe fittings 11 are inserted into both ends of the slurry suction hose 10. The slurry suction hose 10 and the grooved pipe joint 11 are fixed together by a safety clamp 12. The lower limit plate 2 matches the safety clamp 12. Limit frames 16 are connected to both sides of the slider 7. The top of the limit frame 16 is provided with a threaded hole 17. A bolt 18 is threaded inside the threaded hole 17. One end of the bolt 18 abuts against the sliding frame 6. When the slider 7 is adjusted to the appropriate position, the bolt 18 is tightened so that its end presses against the side wall of the sliding frame 6, which can firmly lock the slider 7 and prevent slippage during pressing or lifting, thus ensuring the stability and safety of the entire support system.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In summary, using the above-described technical solution of this utility model, the first step is to accurately insert the grooved pipe connector 11 into one end of the slurry suction hose 10. Next, a safety clamp 12 is placed on the lower limit plate 2, ensuring its correct position to prepare for subsequent precise crimping. Then, the slurry suction hose 10 with the grooved pipe connector 11 installed is placed on the safety clamp 12, ensuring the grooved pipe connector 11 at the near end of the hose is in close contact with the straightening channel steel 15. The position of the slider 7 can then be adjusted according to the slurry suction hose 10.

[0031] After adjustment, tighten bolt 18 to fix slider 7, ensuring no slippage occurs during the entire pressing or lifting process. Then, activate the second hydraulic telescopic rod 8 to lift the slurry suction hose 10 to a horizontal position. Next, place another semi-safety clamp 12 on the slurry suction hose 10 and use calipers or other calibration tools to align it with the lower safety clamp 12. Then, activate the first hydraulic telescopic rod 4 to move the upper limit plate 3 downward, causing the upper limit plate 3 to press against the safety clamp 12. When both safety clamps 12 are in the appropriate position, use screws to tighten the two clamps, achieving reliable locking and sealing between the slurry suction hose 10 and the grooved pipe joint 11.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
