Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The vertical integrated mechanical stopping device of the home elevator is composed of fixed mechanical stopping parts 2 arranged on the upper side and the lower side of a guide rail 1 and a movable mechanical stopping part 4 arranged on an upper beam 3 of a cage as shown in figures 1 to 7.

The fixed mechanical stopping component 2 comprises a mechanical stopping plate 201, a stopping opening 202 is arranged on the mechanical stopping plate 201, and a self-resetting travel switch 203 is arranged on the back of the stopping opening 202.

The type of the self-resetting travel switch can be Shi Mai race elevator limit switch (T4 VH 336-11Z-M20-1058).

The stopping opening 202 is of a U-shaped structure, and the structure is shown in fig. 3.

The shape of the stopping opening 202 can also adopt a J-shaped structure as shown in FIG. 4, which can save materials and reduce manufacturing cost.

The check openings 202 of the fixed mechanical check member 2 attached to the lower side of the guide rail 1 are distributed upward, and the check openings 202 of the fixed mechanical check member 2 attached to the upper side of the guide rail 1 are distributed downward.

The movable mechanical stopping part 4 comprises a shell 401, a bolt component 402 is arranged on the shell 401, a contact component 403 is arranged on the bolt component 402, and a striking bow 404 is arranged at the end part of the bolt component 402; the interior wall of the housing 401 is provided with a passive door switch 405 that cooperates with the contact assembly 403.

The wall of the housing 401 is provided with a kidney-shaped hole 406 which is matched with the bolt component 402.

The kidney-shaped hole 406 includes a long groove 461, and arc-shaped bayonets 462 are disposed at two ends of the long groove 461, and the diameter of the arc-shaped bayonets 462 is greater than the width of the long groove 461.

The bolt assembly 402 comprises a moving rod 421, a threaded rod 422 matched with the waist-shaped hole 406 is arranged on the side surface of the moving rod 421, an operating rod 423 is connected with the threaded rod 422 through external threads, and an internal threaded hole is formed in the operating rod 423.

The moving rod 421 is further provided with a stop tube 424 located inside the bow 404.

And the stop tube 424 mates with the stop port 202.

The number of passive door switch is two, is located the both sides of casing inner wall respectively, cooperatees with the contact subassembly, realizes the monitoring and the feedback to the maintenance state.

The utility model discloses an installation: fixed mechanical stopping components are respectively installed at the upper end and the lower end of the guide rail, a stopping opening of the fixed mechanical stopping component at the upper end faces downwards, and a stopping opening at the lower end faces upwards. The mechanical stop plate is mounted on the guide rail by fasteners.

The movable mechanical stopping component is arranged at the corresponding position of the upper beam of the cage and is matched with the fixed mechanical stopping component to act.

In the non-operating state, the movable mechanical stopping component does not influence the normal operation space.

When the maintenance is needed, firstly, the operating lever in the bolt assembly is rotated outwards, and then the internal threaded rod is moved to the position of the corresponding arc bayonet on the shell, the contact assembly can be contacted with the passive door switch at the position to enter a maintenance state, and meanwhile, the operating lever is rotated inwards (clamped into the arc bayonet), so that the operating lever cannot be moved (only when the operating lever is moved to the position, the elevator can enter the maintenance state, only when the operating lever returns to the original position, the elevator can enter a normal operation state, and the elevator cannot operate under other conditions); at the moment, in an overhaul state, when the lift car moves upwards or downwards to a position fast enough, the impact bow collides with a self-reset travel switch (namely a limit switch) so that the lift decelerates and stops. If the elevator continues to move upwards or downwards due to inertia or other reasons, the blocking opening part on the mechanical blocking plate can collide with the blocking pipe (which can be a rubber round pipe) part in the bolt assembly, so that the elevator is mechanically blocked to move upwards or downwards.
