Embodiment

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 indicated, the technical scheme in the application embodiment effectively solves the above-mentioned emergency disengaging device, seals in an emergency situation through gravity and falling of the blocking block, avoids leakage of liquid in the crane pipe, and solves the technical problem that the disengaging device is not necessarily in a vertical state during fluid loading and unloading, the blocking block cannot timely slide and seal due to the influence of friction, and sealing cannot be completed in time when emergency disengaging occurs. The general idea is as follows:

[0028] In view of the problems in the prior art, the utility model provides a kind of fluid loading and unloading arm emergency disengaging device, including liquid injection pipe 1, liquid injection pipe 1 is slidably installed with the transmission of transmission rod 2, the inside of liquid injection pipe 1 is slidably installed with the sealing of shuttle-shaped column 3, the inside of liquid injection pipe 1 is fixedly installed with the sealing of sealing pad 4, transmission rod 2 is symmetrically installed with the reset of spring 5;Shuttle-shaped column 3 bottom end is fixedly connected with transmission rod 2.

[0029] In summary, when the emergency occurs and the liquid injection pipe 1 and the liquid injection port are separated, the transmission rod 2 will be quickly reset under the elastic force of the two springs 5. The transmission rod 2 will drive the shuttle-shaped column 3 to slide and reset during the reset process, so that the shuttle-shaped column 3 can be inserted back into the sealing gasket 4. When the shuttle-shaped column 3 is inserted into the sealing gasket 4, the outlet of the liquid injection pipe 1 is sealed, avoiding the leakage of the liquid in the liquid injection pipe 1. No matter what angle the liquid injection pipe 1 is at, the sealing can be quickly completed when it is separated, achieving the effect of timely sealing when the emergency separation occurs.

[0030] The two ends of the transmission rod 2 are symmetrically provided with support plates 6 for providing support, and the two ends of the transmission rod 2 are symmetrically provided with threaded rods 7 for driving. The threaded rods 7 are threadedly connected with the support plates 6, and the side ends of the threaded rods 7 are fixedly provided with knobs 8 for rotating. The two sides of the support plates 6 are symmetrically fixedly provided with support rods 9 for force. The support rods 9 are slidably connected with the transmission rod 2.

[0031] In summary, when the size of the liquid injection port is larger, the knob 8 is counterclockwise rotated, which drives the threaded rod 7 to rotate counterclockwise. Since the threaded rod 7 is threadedly connected with the support plate 6, the counterclockwise rotation of the threaded rod 7 will push the support plate 6 to slide outward. After the support plate 6 slides outward, the two support plates 6 can assist the transmission rod 2 to abut against the edge of the liquid injection port when the liquid injection pipe 1 is inserted into the liquid injection port.

[0032] The transmission rod 2 is provided with pressure grooves 11 for assisting the spring 5.

[0033] In summary, the shuttle-shaped column 3 is streamlined, which can reduce the resistance to the flow of liquid as much as possible. When the separation occurs, the liquid flowing in the liquid injection pipe 1 will push the shuttle-shaped column 3 to reset by the pressure grooves 11, further assisting the spring 5 to timely seal the shuttle-shaped column 3.

[0034] Working principle:

[0035] The first step, in use, the liquid injection pipe 1 is inserted into the liquid injection port (the device to be injected liquid), the liquid injection pipe 1 is forced to insert, the transmission rod 2 is abutted against the two ends of the liquid injection port, the transmission rod 2 is resisted to overcome the elastic force of the two springs 5 and slide upward, the transmission rod 2 slides upward, the shuttle-shaped column 3 is lifted upward, the shuttle-shaped column 3 slides upward and is separated from the contact with the sealing pad 4, the liquid in the liquid injection pipe 1 can flow out along the gap between the shuttle-shaped column 3 and the sealing pad 4, and the fluid loading and unloading operation can be smoothly carried out (the liquid injection pipe 1 needs to be continuously inserted into the liquid injection port during the operation), when the liquid injection pipe 1 and the liquid injection port are separated due to an emergency, the transmission rod 2 loses the resistance, the transmission rod 2 is quickly reset under the elastic force of the two springs 5, the transmission rod 2 resets the shuttle-shaped column 3 in the process, so that the shuttle-shaped column 3 can be wiped back into the sealing pad 4, and the outlet of the liquid injection pipe 1 is sealed after the shuttle-shaped column 3 is inserted into the sealing pad 4, so as to avoid the leakage of the liquid in the liquid injection pipe 1.

[0036] The second step, the shuttle-shaped column 3 is streamlined, can reduce the resistance to the liquid flow as much as possible when the liquid flows, when the separation occurs, the liquid flowing in the liquid injection pipe 1 will push the shuttle-shaped column 3 to reset, further assist the spring 5, and the shuttle-shaped column 3 can be sealed in time, when the size of the liquid injection port is larger, the knob 8 is counterclockwise rotated (the angle of view), the knob 8 drives the threaded rod 7 to rotate counterclockwise, since the threaded rod 7 is screwed with the support plate 6, the threaded rod 7 counterclockwise rotation will drive the support plate 6 to slide outward, after the support plate 6 slides outward, the two support plates 6 can assist the transmission rod 2 to abut against the edge of the liquid injection port when the liquid injection pipe 1 is inserted into the liquid injection port.
