Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to a steel wire spring structure for the upper sill device of a side-opening hall door of an elevator. Background Technology

[0002] The landing door sill device plays a crucial role in elevator operation. It not only seals off the landing entrance and car entrance but also plays a vital role in ensuring passenger safety. As the outer door of the elevator, the landing door uses a mechanical locking device and electrical interlocking system to ensure it is locked when closed, preventing accidental opening during elevator operation that could lead to falls or shearing accidents. The opening and closing of the landing door is driven by the car door opening knife, which is electrically interlocked with the car door. The elevator cannot start if the door is not fully closed. Currently, door lock structures commonly use left and right mounting plates on the same side, resulting in a relatively bulky overall structure that is unsuitable in some scenarios. Summary of the Invention

[0003] To address the aforementioned technical problem of a relatively large overall structure, this utility model provides a steel wire spring structure for the elevator side-opening hall door sill device.

[0004] The technical solution of this utility model is as follows: A steel wire spring structure for an elevator side-opening hall door sill device includes a door head base plate assembly, a driven hanging plate assembly, an active hanging plate assembly, and a linkage steel wire rope assembly. The door head base plate assembly includes a top plate and a back plate. The top plate is horizontally positioned at the top of the back plate. Mounting brackets are provided on both sides of the back plate, and a guide rail is provided between the mounting brackets. The roller assembly on the driven hanging plate assembly slides into the inner groove of the guide rail. The steel wire rope of the linkage steel wire rope assembly is wound around both ends of the rope wheel of the driven hanging plate assembly. The steel wire rope fixing bracket is located at the bottom of the middle top plate and is fixed to the rope ends of both ends of the linkage steel wire rope assembly by fasteners. The fixed shaft on the linkage steel wire rope assembly is fixed together with the active hanging plate assembly by nuts. The roller assembly on the active hanging plate assembly slides into the inner groove of the guide rail. The two ends of the counterweight spring are respectively hooked onto the hook and hook assembly of the driven hanging plate assembly. The hook assembly is located at the bottom left side, and the hook is located at the upper right side of the driven hanging plate assembly.

[0005] The guide rail is fixed to both ends of the door head base plate assembly by bolts. The middle part of the mounting bracket has a trapezoidal cross-section. The switch assembly is fixed to the door head base plate assembly by bolts and nuts. The wire rope fixing bracket is riveted to the door head base plate assembly by rivets.

[0006] The driven mounting plate assembly has an inclined plate on top, and a hook is provided on the inclined plate.

[0007] The wire rope fixing bracket is fixed in the middle to the top plate, and the two sides of the wire rope fixing bracket are vertically downward. The wire rope fixing bracket is equipped with fixing components.

[0008] The technical solution of this utility model has a novel structure and a clever and simple design. By setting driven hanging plate components and active hanging plate components on the inner and outer sides of the guide rail, the guide rail length is shorter and the overall structure is compact. There is a linkage steel wire rope component to link the driven hanging plate components and the active hanging plate components. A counterweight spring ensures that the system can reset without pressure, thus guaranteeing strength. The counterweight spring is fixed to the hook and hook assembly, making it very safe and secure.

[0015] like Figure 4 , 56, 7, 8, 9, 10, 11, 12, 12, 13, 14, 15, 16. In use, a switch assembly 6 is located on the bottom left side of the top plate, with a switch box at its bottom. An emergency unlocking assembly 8 is fixed to the corresponding hole at the bottom of the door head base plate assembly 1. A bayonet is located on the right side of the switch assembly 6, and a plug assembly is located on the left side of the active mounting plate assembly 4. A barb 14 is formed on the upper left side of the door lock assembly 5, with a limiting groove 13 below it. A limiting shaft is located in the limiting groove 13 and fixed to the active mounting plate assembly 4. A ball bearing a is located outside the limiting shaft. A limiting block 15 is located at the lower part of the door lock assembly 5, with a limiting rod inside the limiting block 15. The limiting rod is engaged in the movable slot of the active mounting plate assembly 4. A ball bearing b is located on the upper right side of the door lock assembly 5, and a plug assembly is located below the barb 14. The active mounting plate assembly... 4. A mounting plate 19 is provided in the upper middle part. The mounting plate 19 is smaller at the top and larger at the bottom. The upper part is trapezoidal and the lower part is rectangular. The door lock assembly 5 is rotatably mounted on the upper part of the mounting plate 19. There are notches on the upper parts of both sides of the trapezoidal part. The notch on the left side is provided with a wear-resistant block. The emergency unlocking assembly 8 includes a lock sleeve 20, a triangular lock 21, a lock plate 22, a retaining spring 23 and a fixing spring 24. The lower outer wall of the lock sleeve 20 has a recess. The fixing spring 24 is stuck in the recess and fixed to the bottom of the door head base plate assembly 1. The lock sleeve 20 is provided with a triangular lock 21. The upper part of the triangular lock 21 is provided with a mounting block. The mounting block is provided with a mounting hole. The mounting hole of the lock plate 22 is fixed through the mounting hole. The two lock plates 22 are arranged vertically. The upper part of the lock plate 22 is provided with a locking hole. The triangular lock 21 is provided with a insertion hole a. The lock sleeve 20 is provided with a insertion hole b. One end of the retaining spring 23 is stuck in the insertion hole a and the other end is stuck in the insertion hole b. The switch assembly 6 has a downward protrusion in the middle, and its two sides are fixed to the top plate. A latch is provided in the middle of the switch assembly 6, and a limiting outer wall is formed on the right side of the middle of the switch assembly 6. This limiting outer wall contacts the wear-resistant block. The hall door sill device is fixed in the elevator shaft by connecting brackets, expansion bolts, etc. When someone in the elevator car presses the button for the corresponding floor, the elevator car will reach the corresponding floor. After the car stops, the elevator door knife arm will open, and the opened door knife arm will clamp the two door balls on the door lock assembly 5. The moving door balls on the door lock assembly 5 will drive the lock hook to rotate and lift downwards, disconnecting the plug assembly on the lock hook from the switch assembly 6 mounted on the door head base plate assembly 1. The motor on the elevator door operator rotates, driving the door knife via a belt. This causes the active mounting plate assembly 4 to slide on the guide rail 2. The linkage steel wire rope assembly 7, fixed to the active mounting plate assembly 4, moves along with it. Finally, the driven mounting plate assembly 3 moves to the same end as the active mounting plate assembly 4. When it reaches the limit position of the rightmost door head bottom plate assembly 1, it stops moving, the elevator door is fully open, and the counterweight spring is firmly pulled open, allowing people inside and outside the elevator car to freely enter and exit. When someone inside the car presses the close button or no one outside presses the call button within a certain period of time, the motor drives the elevator door knife to close. The force acting on the door ball of the door lock assembly 5 disappears, and the lock hook on the door lock assembly 5 returns to a horizontal state under its own weight.Simultaneously, the counterweight springs 9, fixed to the hooks of the driven mounting plate assembly 3 and the hook assembly 10 respectively, automatically tighten, thereby driving the driven mounting plate assembly 3 to move to the left. The active mounting plate assembly 4 moves along with it under the action of the linkage wire rope assembly 7. When the contact assembly on the door lock assembly 5 inserts into the switch assembly, the limiting device on the base plate assembly stops. The driven mounting plate assembly 3 and the active mounting plate assembly 4 stop moving. At the same time, the plug assembly on the door lock assembly 5 is also fully in contact with the auxiliary contact assembly, and the circuit is fully connected. After receiving the command, the elevator car moves up and down. When the elevator malfunctions and the door cannot be opened normally or needs maintenance, the emergency unlocking assembly 7 can be turned by using a triangular key. The unlocking rod on the emergency unlocking assembly 7, that is, the lock plate 22, moves the limiting rod through the locking hole, pushing the bolt of the door lock assembly 5, thereby lifting the lock hook downward. The outer wall of the lock hook is arc-shaped, so it smoothly engages with the locking slot. When the lock hook is lifted downward, the elevator doors on both sides can be opened by gently pulling them with your hands from the outside of the car.
