Description

Technical Field

[0001] The invention relates to a connection device, in particular to an automatic docking mechanism for explosion-proof connectors, which is mainly used for automatic connection of explosion-proof connectors in explosion-proof places with high automation requirements. Background Art

[0002] Explosion-proof connectors are widely used for electrical and communication connections of various types of equipment in explosion-proof occasions. In explosion-proof occasions, when one device needs to supply power or communicate to another device, the operator usually manually connects the explosion-proof connector to meet this demand. In order to meet the explosion-proof requirements, the flameproof explosion-proof connector usually needs to tighten the locking nut on the female head for more than 10 turns when connecting, rather than simply plugging and unplugging. Therefore, when a device needs to frequently connect and disconnect with another device automatically, the conventional automatic connector connection solution is not applicable. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic docking mechanism for explosion-proof connectors which can realize automated operation, reduce the workload of operators and improve work efficiency.

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] The present invention discloses an automatic docking mechanism for explosion-proof connectors, which is used for docking a male head and a female head of an explosion-proof connector. The female head comprises a female head body and a locking nut. The locking nut is suitable for rotating relative to the end of the female head body. The mechanism comprises a first gear, a second gear and a gear driving device. The gear driving device is connected to the first gear and is suitable for driving the first gear to rotate. The second gear is used to be sleeved outside the locking nut and fixedly connected to the locking nut. The first gear is meshed with the second gear. When the male head extends into the locking nut, the gear driving device drives the first gear to rotate, and the first gear drives the second gear to rotate, thereby driving the locking nut to rotate, thereby completing the connection between the male head and the female head.

[0006] Furthermore, it also includes a guide sleeve, which is connected to the end of the second gear close to the male head, and the male head is first inserted into the guide sleeve when the male head and the female head are connected.

[0007] Furthermore, the guide sleeve and the second gear are welded to each other.

[0008] Furthermore, the second gear is connected to the locking nut via a screw.

[0009] Furthermore, it also includes a base, which is a plate-shaped body, and is provided with a first through hole and a second through hole. The gear drive device passes through the first through hole and is connected to the base, and the second through hole is used to connect to the female head body.

[0010] Furthermore, the gear driving device includes an explosion-proof servo motor and a reducer, and the explosion-proof servo motor drives the first gear to rotate after being decelerated by the reducer.

[0011] Furthermore, the reducer is a planetary reducer.

[0012] Furthermore, it also includes an explosion-proof proximity switch, which is used to measure the distance between the male head and the female head. When the distance between the male head and the female head reaches a predetermined value, the explosion-proof proximity switch controls the explosion-proof servo motor to start, driving the locking nut to tighten.

[0013] Furthermore, the explosion-proof proximity switch is arranged on the base.

[0014] Furthermore, the number of teeth of the first gear is smaller than the number of teeth of the second gear.

[0015] Compared with the prior art, the automatic docking mechanism of the explosion-proof connector of the present invention has at least the following beneficial effects:

[0016] The present invention discloses an automatic docking mechanism for explosion-proof connectors. The mechanism comprises a first gear, a second gear and a gear driving device. The gear driving device is connected to the first gear. The gear driving device is suitable for driving the first gear to rotate. The first gear drives the second gear to rotate by meshing. The second gear is used to be sleeved outside a locking nut and is fixedly connected to the locking nut. Therefore, the locking nut can be tightened by controlling the action of the gear driving device. The mechanism is suitable for connecting explosion-proof connectors of automated equipment, reduces the workload of operators, improves work efficiency, and avoids wrong connection and missed connection of explosion-proof connectors.

The gear driving device 33 is connected to the first gear 31, and the gear driving device 33 is suitable for driving the first gear 31 to rotate. The second gear 32 is used to be sleeved outside the locking nut 22 and fixedly connected to the locking nut 22. The first gear 31 is meshed with the second gear 32. When the male head 01 extends into the locking nut 22, the gear driving device 33 drives the first gear 31 to rotate, and the first gear 31 drives the second gear 32 to rotate, thereby driving the locking nut 22 to rotate and tighten, thereby completing the connection between the male head 01 and the female head 02. The explosion-proof connector automatic docking mechanism of the present invention includes a first gear 31, a second gear 32, and a gear driving device 33. The gear driving device 33 is connected to the first gear 31, and the gear driving device 33 is suitable for driving the first gear 31 to rotate. The first gear 31 drives the second gear 32 to rotate by meshing. The second gear 32 is used to be sleeved outside the locking nut 22 and fixedly connected to the locking nut 22. Therefore, the locking nut 22 can be tightened by controlling the action of the gear driving device 33.
