Description

Technical Field

[0001] This utility model relates to the field of assembly and debugging tooling technology for underwater vehicles, specifically to an auxiliary tooling for inserting and removing safety pins on underwater vehicles. Background Technology

[0002] During the pre-test commissioning of a certain underwater vehicle's control section, it is necessary to connect and disconnect a safety socket in a certain control section of the product. The structure of safety socket 1 is as follows: Figure 1 As shown, the safety socket is disconnected by a safety pin. However, due to the special structure of this safety socket 1, which contains a spring with high rigidity, the only tool currently used is a T-shaped handle 12 (as shown). Figure 2 As shown, the operation process is relatively complicated and slow. It requires two people to work together to connect before debugging and disconnect after debugging. One person uses the T-shaped handle 12 to lift the safety socket 1 upwards, and the other person pulls out or inserts the safety pin 11 into the safety socket 1 before the debugging of the control section 13 can be carried out.

[0003] CN217225404U discloses a lifting tool for a safety socket on a vessel, comprising a rocker and a T-shaped puller, which utilizes the lever principle to lift the safety socket. However, this tool still requires two people to use: one person uses the T-shaped puller to lift the safety socket, while the other person inserts the rocker, locks it in place, and then pries the safety socket upwards. Furthermore, the rocker needs to make way for the pin hole, making its use relatively cumbersome.

[0004] Therefore, there is a need for a safety pin insertion and removal auxiliary tool that can reduce the labor required for debugging the control section of an underwater vehicle and improve work efficiency. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides an auxiliary tool for inserting and removing safety pins on underwater vehicles. By using a handle for lifting, a single person can lift the safety socket with one hand, thereby enabling the insertion and removal of safety pins by a single person, which can effectively improve work efficiency.

[0006] Specifically, this utility model is implemented as follows:

[0007] A safety pin insertion and removal auxiliary tooling for underwater vehicles, comprising:

[0008] The support base supports the safety socket during use;

[0009] The connecting shaft has a threaded section at the bottom for connecting to the threaded hole of the safety socket;

[0010] A lifting handle is slidably connected to the support base and to the connecting shaft for lifting the safety socket.

[0011] Furthermore, the support base is U-shaped overall, and the lifting handle and connecting shaft are located inside the support base. The two sides of the lifting handle are slidably connected to the inner walls of the two sides of the support base.

[0012] Furthermore, the support base includes:

[0013] The support handle is arranged parallel to the lifting handle;

[0014] The support feet are located at both ends of the support handle and together with the support handle form a U-shaped structure. The end of the support foot that contacts the underwater vehicle is arc-shaped.

[0015] Furthermore, the inner walls on both sides of the support base are provided with vertically arranged positioning grooves, and the two sides of the lifting handle are provided with positioning protrusions, which are slidably connected in the positioning grooves.

[0016] Furthermore, the connecting shaft is provided with a knurled section, which is used to rotate the connecting shaft.

[0017] The working principle of this utility model:

[0018] In use, place the fixture above the safety socket, then rotate the connecting shaft to connect it with the threaded hole on the top of the safety socket. Next, press your palm against the support base, with your fingers below the lifting handle, and apply force in a "fist-like" motion to move the lifting handle and its connecting shaft upwards, thus lifting the safety socket upwards to expose the safety pin hole on the side. Insert the safety pin into the safety socket to disconnect it from the underwater vehicle's control section. To restore connection, pull out the safety pin, release the lifting handle, and the safety socket will automatically reset under the action of the internal spring, restoring the connection.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) The underwater vehicle safety pin insertion and removal auxiliary tool provided by this utility model can be completed by a single person, which reduces the labor required for the debugging of the underwater vehicle control section and greatly improves the work efficiency of the operator.

[0021] (2) By using this tooling, the quality hazard of the safety socket being unable to be lifted due to damage to the threaded hole of the safety socket caused by improper operation when using the T-shaped handle at the present stage is eliminated. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 3-4 As shown, this embodiment provides an auxiliary tooling for inserting and removing safety pins on an underwater vehicle, including: a support base 2, a connecting shaft 3, and a lifting handle 4. The support base 2 consists of two support legs 21 and a support handle 22. The bottom of the support legs 21 is arc-shaped, closely fitting the arc-shaped outer surface of the control section 13 of the underwater vehicle, allowing the tooling to be placed above the safety socket 1 of the control section 13. The support handle 22 is horizontally arranged, with its two ends fixedly connected to the two support legs 21, forming a U-shaped structure together with the support legs 21.

[0032] The connecting shaft 3 and the lifting handle 4 are located inside the support base 2. The lifting handle 4 is parallel to the support handle 22, and its two ends are positioning protrusions 41. A positioning groove 23 is provided on the inner side of the support foot 21, and the positioning protrusions 41 are located in the positioning groove 23 and can move up and down along the positioning groove 23. The connecting shaft 3 is a screw rod in whole. Its bottom is used to connect to the threaded hole of the safety socket 1, and its upper part is connected to the lifting handle 4. Specifically, it can be connected by bearings, threads, etc., so that the connecting shaft 3 can rotate. In this embodiment, the connecting shaft 3 and the lifting handle 4 are threadedly connected. The lifting handle 4 is restricted by the positioning protrusions 41 and the positioning groove 23 and cannot rotate axially. Therefore, when the connecting shaft 3 is rotated, only the connecting shaft 3 moves up and down. The connecting shaft 3 is provided with a knurled section 31 so that the operator can rotate the connecting shaft 3 to connect it with the threaded hole of the safety socket 1.

[0033] Specifically, the operating procedure for this tooling is as follows:

[0034] 1) When debugging the control section 13, align the connecting shaft 3 of the tool with the threaded hole of the safety socket 1, and then rotate the connecting shaft 3 downward through the knurled section 31 to screw it into the threaded hole;

[0035] 2) During commissioning, the operator can hold the support handle 22 and the lifting handle 4 of the fixture at any time as needed to connect or disconnect the safety socket 1 from the control section 13. When disconnecting, press the support handle 22 with your palm and place your fingers below the lifting handle 4. Apply force with a "fist" motion to move the lifting handle 4 and its connecting shaft 3 upward, thereby lifting the safety socket 1 upward to expose the radial safety pin hole of the safety socket 1. Then, insert the safety pin 11 into the safety socket 1 to disconnect it from the underwater vehicle control section 13.

[0036] Conversely, when connected, the safety pin 11 is pulled out, the lifting handle 4 is released, and the safety socket 1 is reset by the spring return force, so that the safety socket 1 is in the connected state.

[0037] 3) After the control section 13 is debugged, the operator only needs to rotate the tooling connecting shaft 3 to unscrew the threaded hole of the safety socket 1.

[0038] 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 can make various simple deductions, modifications, or substitutions based on the concept of this invention.
