Description

Technical Field

[0001] This utility model relates to the field of gas cylinder filling operation technology, specifically to an auxiliary tooling for filling CO2 gas cylinders with an electrically operated explosion valve. Background Technology

[0002] The function of the CO2 cylinder with an electrically operated valve is to pressurize the fuel tank by compressing CO2 gas, thereby stabilizing the fuel tank pressure within a certain range during navigation. Specifically, the pressurized CO2 gas released from the CO2 cylinder with the electrically operated valve first enters the forward fuel compartment, compressing the fuel and entering the anti-sway compartment through the front duct of the anti-sway compartment. The fuel in the anti-sway compartment then enters the rear fuel compartment through the rear duct. In this way, the fuel is continuously delivered to the combustion chamber for combustion through the fuel pipe and interlock valve, and the thermal energy is converted into mechanical energy by the engine propulsion system, thereby enabling the underwater vehicle to navigate autonomously.

[0003] Currently, the filling operation of CO2 cylinders with electrically operated valves lacks dedicated auxiliary tooling and is instead completed using an auxiliary platform. This filling method has the following problems:

[0004] (1) CO2 cylinders do not have a dedicated safety protection limit structure, which poses a risk of slipping and falling to the ground.

[0005] (2) The auxiliary platform only serves as a support and lacks functions such as flipping and tilting, which means that only about 2 / 3 of the low-temperature liquid CO2 in the CO2 cylinder can be used normally, and the remaining gas cannot be pressurized to the fuel tank, which is a waste.

[0006] (3) During the filling operation, the operator's hands are easily frostbitten because he / she needs to hold the CO2 cylinder for a long time.

[0007] Therefore, how to effectively reduce or eliminate the safety hazards and reduce the testing costs during CO2 cylinder filling operations is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] To address the aforementioned problems, this invention provides an auxiliary tooling for filling CO2 cylinders with an electrically operated valve. This tooling enables the CO2 cylinder to be flipped. Before flipping, the support frame is locked, and the CO2 cylinder is in a normal filling state. After filling, the CO2 cylinder is flipped, placing it in an inverted position to facilitate subsequent pressurization of the fuel tank. This method effectively improves safety during filling and subsequent use, while also preventing gas waste caused by the inability to flip or tilting of the CO2 cylinder.

[0009] Specifically, this utility model provides an auxiliary tooling for filling CO2 cylinders with an electrically operated valve, comprising:

[0010] Frame;

[0011] A support frame, mounted on the vehicle frame, is used to hold CO2 cylinders. The support frame is configured with a flipping structure for flipping the CO2 cylinders.

[0012] A limiting component, provided on the support frame, is used to limit the tilting angle of the CO2 cylinder;

[0013] A locking assembly, located on the support frame, is used to secure the CO2 cylinder.

[0014] Furthermore, the frame is symmetrically arranged with two columns on both sides, and the top of the column is provided with a bearing seat. The two sides of the support frame are connected to the bearing seat by pins, so that the support frame can rotate around the pin axis.

[0015] Furthermore, the locking assembly includes:

[0016] The curved pressure plate is hinged to the support frame at one end and connected to the support frame at the other end by bolts.

[0017] Furthermore, the limiting component is located on the side where the support frame and the arc-shaped pressure plate are connected by bolts, and it includes:

[0018] The limiting groove plate and the arc-shaped pressure plate are connected to the limiting groove plate by bolts;

[0019] The limiting groove plate is provided with an arc-shaped limiting groove, and the column is provided with a limiting post at the corresponding position of the arc-shaped limiting groove. The limiting post extends into the arc-shaped limiting groove to limit the flipping angle of the CO2 cylinder.

[0020] Furthermore, the end of the arc-shaped pressure plate that is bolted to the support frame is provided with a U-shaped opening.

[0021] Furthermore, the auxiliary tooling for filling CO2 cylinders with electrically operated valves also includes:

[0022] A positioning component is disposed on the side where the arc-shaped pressure plate is hinged to the support frame, the positioning component comprising:

[0023] A positioning pin is inserted into the column and extends through the column toward the support frame;

[0024] A positioning plate is provided on the support frame and corresponds to the position of the positioning pin. It has two positioning holes, and the positioning pin is inserted into the corresponding positioning hole to lock the support frame.

[0025] Furthermore, the support frame is provided with a support plate at the bottom, which is used to support the CO2 cylinder; the support frame is provided with an arc-shaped bracket at the top, which is provided with a wedge-shaped block for supporting the CO2 cylinder after it has been flipped over.

[0026] Working principle:

[0027] During inflation, the CO2 cylinder is placed normally on the support frame and fixed by the locking assembly. After the CO2 cylinder is fixed, the positioning pin is inserted into the corresponding positioning hole of the positioning plate to fix the support frame and prevent it from rotating. At this time, the tooling is in the cylinder filling state. After the CO2 cylinder is filled, the positioning pin is pulled out, the support frame is flipped over, and after it is flipped into place, the positioning pin is inserted into the corresponding positioning hole to flip the cylinder to the inverted state.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] (1) The auxiliary tooling for filling CO2 cylinders with electric explosion valve provided by this utility model can realize the fixing and flipping of CO2 cylinders, which can effectively improve the safety of CO2 cylinder filling process.

[0030] (2) By flipping the CO2 cylinder connector, the liquid CO2 in the CO2 cylinder can flow out normally during use, which solves the problem of waste of liquid CO2 in the CO2 cylinder caused by the inability to tilt and flip. Attached Figure Description

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] Example 1

[0044] like Figure 1 As shown, this embodiment provides an auxiliary tooling for filling CO2 cylinders with electric explosion valves, including: a frame 1, a support frame 2, a limiting component, a positioning component, and a locking component, wherein, as... Figure 2 As shown, the overall structure of the frame 1 is H-shaped. The main body of the frame 1 is welded from channel steel. The bottom of the frame is equipped with movable casters 11 with braking function. Two symmetrically arranged columns 12 are set in the middle of the frame 1. Diagonal bracing is provided on both sides of the columns 12. Bearing seats 61 are set at the top of the columns 12. Figure 3 As shown, the support frame 2 is used to place the CO2 cylinder 7, and its two sides are connected to the bearing seat 61 by pins 6 so that the support frame 2 can be flipped.

[0045] The support frame 2 consists of a U-shaped frame 21, a support plate 22, and an arc-shaped bracket 23. The U-shaped frame 21 is welded together from rectangular square tubes on both sides and an arc-shaped support at the bottom. The support plate 22 is welded to the bottom of the U-shaped frame 21 and is square in shape. It is used to support the bottom of the CO2 cylinder 7. The arc-shaped bracket 23 is located at the top of the U-shaped frame 21. Its inner wall is provided with wedge-shaped blocks 24 to form a wedge-shaped constriction structure, which is used to limit the CO2 cylinder 7 after it is turned over and prevent it from sliding down.

[0046] The locking assembly is mounted on the U-shaped frame 21 of the support frame 2. It is an arc-shaped pressure plate 3, with one end hinged to the U-shaped frame 21 and the other end connected to the locking assembly via bolts 31. The end of the arc-shaped pressure plate 3 connected to the bolts 31 has a U-shaped opening for easy disassembly. The positioning assembly is located on the side where the arc-shaped pressure plate 3 is hinged to the U-shaped frame 21. It includes a positioning pin 51 and a positioning plate 5. The positioning pin 51 extends from the outside of the column 12, passing through the column 12 and towards the U-shaped frame 21. Figure 5As shown, the positioning plate 5 is a square plate fixed to the U-shaped frame 21. It has a pin 6 and two positioning holes 52. The pin 6 is used to connect to the bearing seat 61. The two positioning holes 52 correspond to the two states of the CO2 cylinder 7 (filled state and inverted state). Inserting the positioning pin 51 into the corresponding positioning hole 52 locks the current support frame 2 and the CO2 cylinder 7, preventing them from flipping and ensuring normal operation.

[0047] like Figure 6-8 As shown, the limiting assembly includes a limiting groove plate 4 and a limiting post 42. The limiting groove plate 4 is arranged opposite to the positioning plate 5, and is equipped with a pin 6 and an arc-shaped limiting groove 41. The two pins on the positioning plate 5 and the limiting groove plate 4 are respectively connected to the bearing seats 61 on the two columns 12, thereby supporting the support frame 2 and realizing its flipping function. The limiting post 42 is set on the column 12 and corresponds to the arc-shaped limiting groove 41. The limiting post 42 extends into the arc-shaped limiting groove 41 to limit the flipping angle of the CO2 cylinder 7. A locking nut 32 is installed on the upper part of the limiting groove plate 4. The screw of the bolt 31 is connected to the locking nut 32 to realize the locking function of the CO2 cylinder 7.

[0048] Specifically, such as Figure 9 As shown, its usage process is as follows:

[0049] (1) When filling CO2 cylinder 7 with live explosive valve, pull out the positioning pin 51 on the frame 1 from the positioning hole 52 of the positioning plate 5, rotate the support frame 2, and when the support frame 2 is in the filling position, insert the positioning pin 51 on the frame 1 into the positioning hole 52 of the positioning plate 5. At this time, the bottom of CO2 cylinder 7 is facing down, and the support frame 2 and CO2 cylinder 7 are in the locked state of the filling position, that is, CO2 cylinder 7 is in the normal filling state.

[0050] (3) After the filling operation of CO2 cylinder 7 with electric explosion valve is completed, pull out the positioning pin 51 on the frame 1 from the positioning hole 52 of the positioning plate 5, rotate the support frame 2, and when the support frame 2 is in the inverted position, insert the positioning pin 51 on the frame 1 into the positioning hole 52 of the positioning plate 5. At this time, the top (connector end) of CO2 cylinder 7 is facing down, and the support frame 2 and CO2 cylinder 7 are in the inverted position locked state, that is, CO2 cylinder 7 is in the normal resting state, and the fuel tank can be pressurized in this state later.

[0051] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
