Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a safety limiting device of an isolation lock of a rail transit vehicle door system, which has a compact structure, is easy to realize and can prevent the isolation lock from being started when a vehicle door is opened.
The technical scheme for achieving the purpose is as follows: the safety limiting device of the isolation lock of the rail transit vehicle door system comprises a first door page, a second door page, an isolation lock rod arranged at the top of the first door page and an isolation lock rod limiting component;
the isolating lock rod limiting component comprises a locking shaft support, a spring and a locking shaft with a lock head structure; the locking shaft support is fixed at the top of the first door leaf, the locking shaft is slidably inserted into the locking shaft support, the spring is sleeved outside the locking shaft, and the lock head structure is arranged at the end part of the locking shaft; a limit groove is formed in the isolation lock rod;
when the first door leaf and the second door leaf are in an open state, the lock head structure is clamped in the limit groove;
when the first door leaf and the second door leaf are in a closed state, the lock head structure is positioned outside the limit groove.
Further, an adjusting arm is arranged at the top of the second door page, and an adjusting screw is arranged on the adjusting arm; when the first door leaf and the second door leaf are in an open state, the adjusting screw is in non-contact with the lock head structure; when the first door leaf and the second door leaf are in a closed state, the adjusting screw pushes the lock head structure to be separated from the limit groove.
Still further, the adjusting arm is provided with an inserting port, and the isolating lock rod passes through the inserting port to be connected with the first door leaf.
Still further, be equipped with the auxiliary regulation arm on the regulation arm, set up adjusting screw connecting hole on the auxiliary regulation arm, adjusting screw passes the adjusting screw connecting hole sets up on the auxiliary regulation arm, and right side is relative to the tapered end structure.
The invention relates to a safety limiting device of an isolation lock of a rail transit vehicle door system, which comprises an isolation lock rod provided with a limiting groove and an isolation lock rod limiting component; in the state that the door leaf is opened, the lock head structure of the isolation lock rod limiting component is clamped in the limiting groove, so that the effect of limiting the motion of the isolation lock rod is achieved, and the isolation lock is disabled; in the state that the door leaf is closed, the lock head structure is ejected out of the limit groove, so that the degree of freedom of the isolation lock rod is released, and at the moment, the isolation lock rod can be operated to open the isolation lock, so that the door leaf loop is bypassed.
Drawings
FIG. 1 is a schematic diagram of a safety stop device of an isolation lock for a rail transit vehicle door system of the present invention;
FIG. 2 is a schematic view of the structure of a safety restraint device of a rail transit vehicle door system isolation lock with an adjustment arm of the present invention;
fig. 3 is a schematic front view of the safety restraint of the rail transit vehicle door system isolation lock with the adjustment arm of the present invention.
Detailed Description
For a better understanding of the technical solutions of the present invention, the following detailed description is made by way of specific examples in conjunction with the accompanying drawings:
referring to fig. 1 to 3, the safety limiting device of an isolation lock for a rail transit vehicle door system of the present invention includes a first door leaf 11, a second door leaf 12, an isolation lock rod 2 disposed at the top of the first door leaf, and an isolation lock rod limiting assembly.
The isolating lock bar limiting assembly includes a lock shaft support 31, a spring 32, and a lock shaft 33 with a lock head structure 34. The locking shaft support 31 is fixed at the top of the first door leaf 11, the locking shaft 33 is slidably inserted into the locking shaft support 31, the spring 32 is sleeved outside the locking shaft, and the lock head structure 34 is arranged at the end part of the locking shaft 33. The isolating lock rod 2 is provided with a limit groove 21.
When the first door leaf 11 and the second door leaf 12 are in the open state, no external force is applied to the lock head structure 34, and the locking shaft 33 acts outwards under the action of the restoring force of the spring 32, so that the lock head structure 34 is clamped in the limiting groove 21 to limit the lifting of the isolating lock rod 2. At this time, even if the key is rotated, the isolating lock lever 2 cannot be lifted, and therefore, when the door is opened, the isolating lock cannot be used, and the isolating lock is in a disabled state.
When the first door leaf 11 and the second door leaf 12 are in the closed state, the locking head structure 34 is separated from the limit groove 21 by manpower or external force, and the degree of freedom of the isolating lock lever 2 is released. At this time, the isolating lock is operated by using a key, the isolating lock rod 2 can be lifted up to activate the isolating switch, the driver is informed that the door is isolated, the safety loop is bypassed, namely, the isolating function is realized, and the safe driving can be continued.
Referring to fig. 2 and 3, in order to realize automatic detachment of the lock head structure 34 when the first door leaf 11 and the second door leaf 12 are in a closed state, an adjusting arm 4 is provided at the top of the second door leaf 12, an inserting port is provided on the adjusting arm 4, the isolating lock rod 2 passes through the inserting port to be connected with the first door leaf 11, an auxiliary adjusting arm 41 is provided on the adjusting arm 4, an adjusting screw connecting hole is provided on the auxiliary adjusting arm 41, and an adjusting screw 42 passes through the adjusting screw connecting hole to be provided on the auxiliary adjusting arm 41 and faces the lock head structure 34.
The set screw 42 is not in contact with the lock cylinder structure 34 when the first door leaf 11 and the second door leaf 12 are in the open state.
When the first door leaf 11 and the second door leaf 12 are in the closed state, the adjusting screw 42 pushes the lock head structure 34 to be separated from the limit groove 21, so that the automatic unlocking function of the isolation lock is realized when the door is closed.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the invention, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the invention as long as they fall within the true spirit of the invention.
