[0032] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0033] like Figures 1 to 5 As shown, a comprehensive hydraulic conduit training platform for multiple skills training includes a main body, basic training platforms 7 for hydraulic conduit assembly and disassembly on the left and right sides, and complex working condition training areas 8 on the front and rear sides. The main body of the training platform is a frame structure, including a main frame 1, two pull-out tool tables 2, two panel frames 3, two sets of panel frame support rods 4, two sets of complex working condition cavities for hydraulic conduit assembly and disassembly 5, and four drawers 6. The main frame is a rectangular cavity structure with an open front, welded from square steel pipes and steel plates. Casters are installed at the four corners at the bottom. The four drawers and two pull-out tool tables are installed in the cavity in the middle of the platform. The drawers and pull-out tool tables are fixed on both sides by ultra-quiet load-bearing slide rails. Training tools and various accessories are placed inside the drawers.

[0034] The hydraulic conduit dismounting basic training platform is composed of a hydraulic conduit dismounting basic operation panel 9 and various types and sizes of pipe joints (straight joint 15, four-way joint 18, right-angle joint 21, three-way joint 22), conduits (conduit 13, conduit 16, conduit 17), single-row pipe clamp 19, double-row pipe clamp (double-hole double-row pipe clamp 24, three-hole double-row pipe clamp 25), 8-shaped pipe clamp 26, P-shaped clamp 11, saddle-shaped clamp 14, rubber hose 10, stainless steel braided hose 20 and hand-operated reversing valve 12. Conduit 13, Conduit 16, Conduit 17), single-row pipe clamp 19, double-row pipe clamp (double-hole double-row pipe clamp 24, three-hole double-row pipe clamp 25), 8-shaped pipe clamp 26, P-shaped clamp 11, saddle-shaped clamp 14, rubber hose 10, stainless steel braided hose 20 and hand-operated reversing valve 12, various types of pipe joints are connected together through conduits and pipe joint sleeve nuts, and the pipe joint sleeve nuts are provided with fuse holes.

[0035] The conduit is provided with a plug cap 23.

[0036] The trainees can perform hydraulic conduit and pipe joint dismounting training and sleeve nut fuse dismounting training.

[0037] The hydraulic conduit dismounting basic training platform is cut from 2.5mm-thick stainless steel plate, and after being subjected to original wire drawing treatment, the panel is printed with "hydraulic conduit dismounting basic training platform", and the surface is coated with transparent protective paint.

[0038] The complex working condition training area is designed in reference to the central wing lower hydraulic system pipeline on a real airplane: including various types of joints (straight, right-angle, three-way and four-way), various pipe diameters (φ6 conduit 30, φ8 conduit 32, φ10 conduit 27, φ12 conduit 28, φ14 conduit 31, φ16 conduit 29), various fixing modes (single-row pipe clamp, P-shaped clamp and saddle-shaped clamp), finished oil filter 33, etc. The pipeline layout presents a three-dimensional form and is more complex, so that the trainees can actually understand the difficulties and key points of hydraulic conduit installation under complex working conditions on an airplane.

[0039] Further, the overall frame is welded from 50mm*50mm*3mm square tubes and 2mm steel plates.

[0040] Further, the panel frame is welded from angle steel, and the upper end of the frame is connected to the top end of the main body frame through a hinge, so that it can be opened and closed through the hinge, and the opening and closing mechanism is in the form of buckles, and five fixing angles are designed corresponding to five buckle slots, and the maximum opening and closing angle is 45°.

[0041] Further, the complex working condition operation cabin is made of 2mm-thick 45# steel plate, which is connected to the main body frame as a whole through a special welding process.

[0042] The hydraulic conduit comprehensive training platform using the multiple skill training can train the trainees in hydraulic conduit installation skills, master the hydraulic conduit installation procedures and installation methods, and train the trainees in the installation of hydraulic conduits under complex working conditions.

[0043] Disassembly training of conduit and pipe joint, disassembly of pipe: first, remove the safety nut on the outer sleeve nut of the hydraulic conduit disassembly training platform 7, and do not twist the nut without removing the safety nut. When disassembling the pipe, first determine the rotation direction of the outer sleeve nut. The direction of the outer sleeve nut can be determined using the right hand rule. Extend your right hand and make a fist, with your thumb pointing in the direction the outer sleeve nut needs to move. The direction of your four fingers is the direction the outer sleeve nut should be twisted. Use one wrench to fix the hexagonal pipe joint, and the other wrench to fix the hexagonal outer sleeve nut. Then, turn the wrench on the outer sleeve nut counterclockwise to loosen it. Do not use only one wrench to twist the outer sleeve nut without fixing the pipe joint, as this may cause the pipe to twist and be damaged. Storing the pipe: the training platform is equipped with a conduit hanger. During training, the disassembled conduit can be hung on the hanger to prevent damage to the conduit. Installing the pipe: first, align the flared end of the conduit with the tapered surface of the pipe joint and press them together. Then, use your hands to tighten the outer sleeve nut onto the pipe joint until it cannot be tightened further. Use two wrenches to tighten the outer sleeve nut: use one wrench to fix the hexagonal pipe joint, and the other wrench to fix the hexagonal outer sleeve nut. Then, turn the wrench on the outer sleeve nut clockwise to tighten it. Do not use only one wrench to twist the outer sleeve nut without fixing the pipe joint, as this may cause the pipe to twist and be damaged. The torque of the tightened outer sleeve nut should be determined based on the material, diameter, and working pressure of the pipe.

[0044] Training on the installation and removal of safety wire for outer sleeve nut: first, determine the tension direction of the safety wire and position the safety hole. Then, according to the safety position and the size of the safety hole, select the appropriate size of the safety wire and cut the appropriate length, straighten it, and then pass it through the safety starting point (should pass through the more difficult end first). Fold and tighten the safety wire, so that the outer safety wire is tightly attached to the bolt head and pressed below the perforated safety wire, then make the first twist knot at the safety starting point with a twist angle of 120°. Make a twist knot with a twist angle of 60°, and keep the safety wire tight during the process. When the distance between the twist knot and the next safety hole is less than 3mm, stop the process. Use flat-nose pliers or fish-mouth pliers to tighten and straighten the twisted safety wire between the two fasteners, and pass one safety wire through the second fastener safety wire. At the same time, tighten the two safety wires, so that the outer safety wire is tightly attached to the bolt head and pressed below the perforated safety wire, then make the first twist knot with a twist angle of 120°. Finally, make 4-7 twist knots with a twist angle of 60° counterclockwise, and slightly tighten them with fish-mouth pliers or flat-nose pliers. Use wire clippers (oblique pliers) to cut off the excess safety wire, leaving 4-6 twist knots at the end. Use fish-mouth pliers or flat-nose pliers to bend the braid tail and press it against the side of the fastener in the direction of the safety wire to complete the installation training of the outer sleeve nut safety wire. The removal method can be referred to the installation method.

[0045] Hydraulic conduit disassembly and assembly basic training platform sealing test: first, the air outlet joint of the hand-operated air pressure pump is connected with the reserved pressure charging joint of the hydraulic conduit disassembly and assembly basic training platform through a rubber hose, and the sealing of the φ10 pipeline is tested. First, the reversing valve is in the closed state, the pressure rod is repeatedly pressed down, and the value of the pressure gauge is observed. When the predetermined pressure is quickly reached, the pressure rod is stopped, the air pressure is fine-tuned through the fine-tuning pressure rod, and the value of the pressure gauge is observed. When the predetermined pressure is reached, the φ10 pipeline is filled with air pressure. Wait for a period of time, and observe the pressure change of the pressure gauge. If the pressure does not change, the φ10 pipeline is sealed well, and the next step of testing can be performed. If the pressure decreases, it indicates that there is a joint leak in the φ10 pipeline. After finding the leak and resealing it, the next step of testing is performed. For φ6 pipeline air pressure test, adjust the hand-operated reversing valve handle to the right lower position, and then the φ10 conduit is connected with the φ6 pipeline through the hand-operated reversing valve. Then the pressure rod is repeatedly pressed down, and the value of the pressure gauge is observed. When the predetermined pressure is quickly reached, the pressure rod is stopped, the air pressure is fine-tuned through the fine-tuning pressure rod, and the value of the pressure gauge is observed. When the predetermined pressure is reached, the φ10 and φ6 pipelines are filled with air pressure. Wait for a period of time, and observe the pressure change of the pressure gauge. If the pressure does not change, the φ6 pipeline is sealed well, and the next step of testing can be performed. If the pressure decreases, it indicates that there is a joint leak in the φ6 pipeline. After finding the leak and resealing it, the next step of testing is performed. For Φ8 pipeline air pressure test, adjust the hand-operated reversing valve handle to the right upper position, and then the φ10 conduit is connected with the φ8 pipeline through the hand-operated reversing valve. Then the pressure rod is repeatedly pressed down, and the value of the pressure gauge is observed. When the predetermined pressure is quickly reached, the pressure rod is stopped, the air pressure is fine-tuned through the fine-tuning pressure rod, and the value of the pressure gauge is observed. When the predetermined pressure is reached, the φ10 and φ8 pipelines are filled with air pressure. Wait for a period of time, and observe the pressure change of the pressure gauge. If the pressure does not change, the φ8 pipeline is sealed well. If the pressure decreases, it indicates that there is a joint leak in the φ8 pipeline. After finding the leak and resealing it.

[0046] After the pressure test is completed, the pressure in the test conduit is discharged by rotating the air release valve. The connecting hose is loosened and placed in its original position.

[0047] The above is only a further embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the scope disclosed by the present application, which belongs to the protection scope of the present application.
