Description

Technical Field

[0001] This utility model relates to the field of DES operating mechanism technology, and in particular to a DES three-position opening and closing position interlocking device. Background Technology

[0002] Currently, the industry's solutions for locking the opening and closing positions of DES all involve adding opening and closing positioning holes to the DES main body's transmission crank arm for locking. This structure is complex and not conducive to operation by maintenance personnel. They need to climb up to the main body to lock the position, which is extremely inconvenient. Furthermore, there is no locking electric circuit, which poses a risk of burning out the motor. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a DES three-position opening and closing position interlocking device, which can reliably lock the DES in the opening or closing state to ensure the operation safety of maintenance personnel.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a DES three-position opening and closing position interlocking device, the innovation of which is: including an interlocking plate baffle, a camshaft, a plug, a limit bolt and a motor output shaft; the interlocking plate baffle, camshaft, plug and motor output shaft are all installed on the DES operating mechanism;

[0005] The camshaft is mounted on the panel of the DES operating mechanism, and the end of the camshaft located inside the DES operating mechanism is engaged with the limit switch of the drive motor circuit, while the end of the camshaft located outside the DES operating mechanism is equipped with a locking plate baffle.

[0006] The locking plate baffle includes a triangular base plate and a limiting plate; the triangular base plate is in the shape of a right triangle and is fixedly installed on the end of the camshaft; the limiting plate has a pair and is respectively perpendicularly arranged on the two right-angled sides of the triangular base plate; the limiting plate is provided with positioning holes, and the axial directions of the positioning holes on the two limiting plates are perpendicular to each other.

[0007] The plug is installed on the panel of the DES operating mechanism, and the end of the plug located inside the DES operating mechanism is engaged with the motor output shaft. The end of the plug located outside the DES operating mechanism is provided with a limit hole perpendicular to the axis. The limit hole on the plug is engaged with the positioning hole on the two limit plates through limit bolts to achieve locking in the locked state and the closed state.

[0008] Furthermore, the end of the plug located inside the DES operating mechanism is provided with a limiting protrusion, and the motor output shaft is provided with a limiting groove that cooperates with the limiting protrusion.

[0009] Furthermore, the locking plate baffle is linked with the camshaft, which can drive the motor circuit limit switch to open or close. When the locking plate baffle is placed in the unlocking slot corresponding to the plug, the plug is separated from the motor output shaft, and the camshaft is separated from the drive motor circuit limit switch, allowing the DES operating mechanism to operate normally electrically. When the locking plate baffle is placed in the locking slot, the plug is inserted into the motor output shaft, and the camshaft will disconnect from the drive motor circuit limit switch, preventing the DES operating mechanism from operating electrically or manually. The DES operating mechanism can reliably lock in the open or closed position.

[0010] The advantages of this utility model are:

[0011] 1) In this utility model, by setting a locking plate baffle structure, in the electric state, the limit bolt is removed, and the locking plate baffle is rotated 45° to disengage it from the unlocking groove; then the plug is pressed inward so that the end of the plug is embedded in the motor output shaft; then the locking plate baffle is rotated until the other end enters the locking groove, and then the fixing bolt is installed to switch to the locked state; this DES opening and closing position locking scheme can reliably lock the DES in the opening or closing state, ensuring the operation safety of maintenance personnel.
