Description

Technical Field

[0001] This utility model belongs to the field of safety device technology, and in particular relates to a locking device for preventing misoperation of emergency gate openers. Background Technology

[0002] Traditional anti-misoperation locking devices use a key-shaped drop indicator at the lock ring. When in use, the drop indicator is pulled out forcefully to open the outer cover for emergency braking. This structure has two drawbacks: first, the drop indicator is easy to fall off if it is not securely fastened, and difficult to pull open if it is too secure; second, it is troublesome to re-tie the rope after one use. Summary of the Invention

[0003] To address the problems in the prior art, this utility model provides a locking device for preventing misoperation of an emergency gate. The technical solution is as follows: it includes a ring, one end of which is sleeved with a chain, and the other end of the chain is connected to a locking mechanism. The locking mechanism includes a pressing plate, which is set on a first base plate. Two columns are set at the center of the first base plate, and collars are sleeved on the columns. One side of the collar is fixedly connected to an intercepting rod, and a limiting rod is provided at the lower part of the intercepting rod. A sliding groove is provided on the first base plate.

[0004] In a preferred embodiment, a protrusion extends from the lower part of the first base plate, and a spring is sleeved on the protrusion. The end of the spring away from the first base plate is sleeved with a protrusion on the second base plate.

[0005] In a preferred embodiment, the diameter of the second base plate is larger than that of the first base plate, and a lifting plate is provided at the edge of the second base plate.

[0006] In a preferred embodiment, the top of the lifting plate is flush with the first base plate.

[0007] In a preferred embodiment, the side wall of the lifting plate is provided with a connecting ring, and the other end of the chain is connected to the locking mechanism through the connecting ring.

[0008] In a preferred embodiment, the slide is a quarter-circle arc with the bottom center of the column as the center, and both ends of the slide are provided with grooves of the same length as the limiting rod.

[0009] In a preferred embodiment, the length of the interceptor bar is greater than the radius of the gate's locking ring.

[0010] In a preferred embodiment, the diameter of the circular ring is larger than the diameter of the locking ring of the circuit breaker.

[0011] In a preferred embodiment, the distance between the upper surface of the first base plate and the lower surface of the pressing plate is X cm, the height of the intercepting rod is Z cm, and the maximum compression of the spring is Y cm, where XZ≤Y.

[0012] The beneficial effects of this utility model are:

[0013] This device changes the interceptor bar from an "I" shape to an "|" shape by pressing the pressure plate to compress the spring, which in turn lifts the lifting ring on the lifting plate. This eliminates the problem of whether the rope is secure, improves the stability of operation in emergencies, and reduces the occurrence of accidents. After handling the emergency, pressing the pressure plate again will restore the interceptor bar to the "I" shape. It is simple to operate and highly efficient. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-6The diagram shows a locking device for preventing misoperation of an emergency gate, comprising a ring 1, one end of which is sleeved with a chain 2, and the other end of which is connected to a locking mechanism 4. The locking mechanism 4 includes a pressing plate 401, which is mounted on a first base plate 402. Two columns 404 are mounted at the center of the first base plate 402, and a collar 405 is sleeved on the column 404. One side of the collar 405 is fixedly connected to an intercepting rod 403. A limiting rod 410 is provided at the lower part of the intercepting rod 403. A sliding groove 411 is provided on the first base plate 402.

[0025] Furthermore, a protrusion extends from the lower part of the first base plate 402, and a spring 408 is sleeved on the protrusion. The end of the spring 408 away from the first base plate 402 is sleeved with a protrusion on the second base plate 406.

[0026] Furthermore, the diameter of the second base plate 406 is larger than the diameter of the first base plate 402, and a lifting plate 407 is provided at the edge of the second base plate 406.

[0027] Furthermore, the top of the lifting plate 407 is flush with the first base plate 402.

[0028] Furthermore, a connecting ring 409 is provided on the side wall of the lifting plate 407, and the other end of the chain 2 is connected to the locking mechanism 4 through the connecting ring 409.

[0029] Furthermore, the slide groove 411 is a quarter-circle arc, with the bottom center of the column 404 as the center, and both ends of the slide groove 411 are provided with grooves of the same length as the limiting rod 410.

[0030] Furthermore, the length of the interceptor bar 403 is greater than the radius of the gate locking ring 3.

[0031] Furthermore, the diameter of the ring 1 is larger than the diameter of the gate locking ring 3.

[0032] Furthermore, the distance between the upper surface of the first base plate 402 and the lower surface of the pressing plate 401 is X cm, the height of the intercepting rod 403 is Z cm, and the maximum compression of the spring 408 is Y cm, where XZ≤Y.

[0033] The above-mentioned device operates as follows: In the locked state, the intercepting rod 403 is parallel to the gate locking ring 3. When the ring 1 is lifted, the sum of the lengths of the two intercepting rods 403 is greater than the diameter of the gate locking ring 3. At this time, the locking mechanism 4 cannot pass through the gate locking ring 3, and the gate casing cannot be opened. If an emergency requires opening the gate casing, simply press the pressing plate 401 and press against the second base plate 406. At this time, the spring 408 is compressed, and the second base plate 406 rises, causing the lifting plate 407 to rise. During the rise, the intercepting rods 403 are lifted, causing the limiting rod 410 to disengage from the deep groove of the slide groove 411 and move to the shallow groove. The ring 1 is then lifted, and the intercepting rods 403 strike the gate locking ring 3, causing it to... Rotate around the column 404. At this time, the limit rod 410 slides to the deep groove at the other end of the slide groove 411. The limit rod 410 is perpendicular to the gate lock ring 3. At this time, continue to lift the ring 1 to pass the locking mechanism 4 through the gate lock ring 3, unlock the gate housing, and perform an emergency braking operation. During the restoration operation, pass the locking mechanism 4 through the gate lock ring 3, press the pressing plate 401 and press against the second base plate 406. The principle is the same as the unlocking situation. Bend the limit rod 410 to the deep groove at the other end of the slide groove 411, release the pressing plate 401, and the spring 408 returns to its original state. At this time, the intercepting rod 403 is horizontal to the gate lock ring 3, and the limit rod 410 is locked by the deep groove of the slide groove 411 and cannot move, thus completing the locking operation.
