Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. An elevator limiting device is shown in fig. 1-5, and comprises an integrated maintenance and limiting mechanism 1 positioned at the upper end of a car guide rail, a lower limiting mechanism 2 positioned at the lower end of the car guide rail, and a triggering mechanism 3 positioned at the top or upper beam of an elevator car.
The integrated maintenance and limiting mechanism 1 comprises an upper limiting plate 101, wherein a lower opening guide groove 102 is formed in the upper limiting plate 101, and an upper stop switch beating plate 103 and an upper stop switch 104 are arranged above the lower opening guide groove 102; the lower open guide slot 102 is flanked by bayonet assemblies 105.
The bayonet lock assembly 105 includes bayonet lock seats 151 located at two sides of the lower opening guide slot 102, bayonet lock 152 is provided on the bayonet lock seats 151, bayonet lock strike plates 153 are provided on the bayonet lock 152, and a matched bayonet lock switch 154 is provided at the tail end of the bayonet lock 152.
The lower limit mechanism 2 comprises a lower limit plate 201, an upper opening guide groove 202 is arranged on the lower limit plate 201, and a lower stop switch beating plate 203 and a lower stop switch 204 are arranged below the upper opening guide groove 202.
The triggering mechanism 3 comprises a base 301, a movable limiting stop rod 302 is arranged on the base 301, and a verification switch 303 is arranged at the tail end of the base 301.
The side end of the limit stop lever 302 is provided with a handle 304, and the base 301 is provided with a corresponding clamping groove 305.
When the car overhauls and runs to an integrated overhauling and limiting mechanism or a lower limiting mechanism, a limiting stop rod triggers a stop switch through a stroke to stop the elevator; when the elevator serves as an operation platform and stops at the upper limit position, the bayonet lock is pushed out to limit the vertical movement of the limiting stop rod, so that the elevator car is fixed, and the function of overhauling the clamping plate is realized.
The utility model adopts the technical scheme that a limit stop lever arranged on a car roof or an upper beam is manually operated before an maintainer enters a hoistway, so that the limit stop lever protrudes out of a car. When personnel go up the sedan-chair top and overhaul the operation elevator, the spacing shelves pole with integral type overhaul and stop gear, lower stop gear (install on the car guide rail) cooperation. When the car overhauls and runs to the upper integrated overhauling and limiting mechanism, the limiting stop rod triggers the upper stop switch to beat the plate and the upper stop switch through the stroke so as to stop the elevator. The lower limit mechanism is realized in the same way.
When the elevator serves as an operation platform to stop at the upper limit position and a host machine and related accessories are required to be overhauled, the bayonet lock on the upper limiting plate is pushed out, and the vertical movement of the limiting stop rod is limited after the bayonet lock is pushed out, so that the elevator car is fixed, and at the moment, the integrated overhauling and limiting mechanism becomes an overhauling clamping plate functionally. Both are logically connected in series. The recovery to the normal state is the reverse operation. The clamping pin is restored firstly, the function of the overhaul clamping plate is removed, an operator restores the limit stop lever on the upper beam after normally withdrawing from the well, and the elevator can run all strokes of the well to serve all landing stations.
The using steps are as follows: a, an operator stretches into the top of a car outside a hoistway to push out a limit stop lever, a verification switch is arranged at the tail end of the limit stop lever, and the limit stop lever can only run when the elevator is completely pushed out or contracted into place;
b, operating the elevator on the upper car roof, opening the elevator to a certain height at the upper part of a hoistway, arranging an upper stop switch beating plate on an upper limit plate at a specific height for ensuring the safety space of personnel on the car roof, and pushing the upper stop switch beating plate to act to stop the switch by the upward movement stroke of a limit stop lever so as to stop the car, wherein the upper stop switch beating plate and the limit stop lever are provided with collision buffering so as to mechanically prevent the elevator from ascending; the same downlink limiting process is adopted;
And c, manually pushing out the bayonet lock on the upper limiting plate when the upper part of the lift car has enough safety space and parts such as a main machine, a traction sheave and the like are required to be maintained, so that a closed shape is formed between the bayonet lock and a lower opening guide groove on the upper limiting plate, and the lift car is prevented from descending. The bayonet lock is provided with a bayonet lock beating plate which is matched with the bayonet lock switch to verify the unique position of the bayonet lock when the bayonet lock is withdrawn;
the trigger mechanism, which is constructed as shown in figure 2,
The base can be arranged on the upper beam or the top of the car, an maintainer can adjust the position of the limit stop lever by stirring the handle of the limit stop lever, and only two designed position electric loop passages allow the elevator to run electrically; the buffer rubber is arranged at the head part of the limit stop lever, so that the shock absorption can be carried out when the limit stop lever is impacted under extreme conditions.
The size and the position of the upper stop switch beating plate are designed to enable the upper stop switch beating plate to be triggered when the limit stop rod is positioned above the clamping pin, and the upper stop switch beating plate is forced to rotate along the center so as to push the upper stop switch to act. At this time, the upper limiting plate has any space for the elevator to go upwards, so that the stopping distance is ensured.
The bayonet lock cardboard can trigger the normally closed bayonet lock switch when the bayonet lock is retracted to the closed state, guarantees that the safety circuit disconnection when last limiting plate becomes the maintenance cardboard.
When the integrated maintenance and limiting mechanism only plays the upper limiting function, the bayonet lock does not need to act (remains at the position of the switch of the bayonet lock). The refitting device meets the requirements of the standard GBT 21739-2008.5.3.2 part of the home elevator on the upper limit device.
The lower limiting mechanism cancels the parts such as the bayonet lock component, the bayonet lock switch and the like on the basis of the integrated maintenance and limiting mechanism. The function and structure meet the requirements of the mechanical stopping device under the standard GBT 21739-2008.4.2 part of the home elevator.
