Abstract
The utility model relates to the technical field of elevators, and discloses a landing door limiting device for elevator maintenance. The landing door limiting device comprises a base arranged on a lift car. The base is fixedly installed above a framework, facing a landing door, of the lift car. The base is connected with a limiting pin through a rotating component. When rotates to the horizontal position, the limiting pin penetrates through the landing door. When rotates to the vertical position, the limiting pin is attached to the frame side of the lift car. According to the landing door limiting device, when a maintenance worker works on a car roof, the landing door is reliably limited, the danger caused by facts that the landing door is self-closed and articles fall into a hoistway is avoided, and the safety of the maintenance worker and an elevator hoistway device is guaranteed. At the same time, the landing door limiting device can be packed up freely, so that normal operation of an elevator is not hindered.
Description
Technical field
The utility model relates to the elevator technology field, relates in particular to a kind of elevator reparing Room thresholding device processed.
Background technology
In the operation of part cage top overhauling, need to keep Room door opening-wide state.At present, still do not have specialized equipment and Room door is carried out spacing, the maintainer generally adopts screwdriver or simple and easy block to snap in the mode of lading door dill, carries out spacing to Room door.The mode that snaps in sill with screwdriver or simple and easy block carries out because Room door has certain self-closing power, being easy to take place spacing inefficacy in the operation when spacing, and Room door automatically resets and causes crushing personnel's event and take place.And the easy loosening hoistway or played into hoistway by personnel's mistake and to cause danger or cause the damage of lift facility of dropping of these limited objects.
The utility model content
The purpose of this utility model is in order to address the above problem, to provide a kind of elevator reparing with Room thresholding device processed, the staff need be kept in the operation of sedan-chair top under the unlimited situation of Room door, realizing reliably spacing to Room door.
The technical scheme that the utility model is taked is:
A kind of elevator reparing Room thresholding device processed, it is characterized in that, comprise the pedestal that is arranged on the car, described pedestal is fixedly mounted on car in the face of the framework top of Room door, on described pedestal, connect locating dowel pin by turning unit, described locating dowel pin penetrates when rotating to level attitude in the door of the described Room, and described locating dowel pin is attached at described car frame side when rotating to vertical position.
Further, fixedly mount telescoping mechanism on the described pedestal, described telescoping mechanism has a flexible end that can protrude upward, and described turning unit is installed in the flexible end of described telescoping mechanism.
Further, described pedestal is positioned at described car frame near the position of car frame side.
Stretch out the described Room outdoors when further, described locating dowel pin rotates to level attitude.
Further, the maximum elongation amount of the flexible end of described telescoping mechanism is 50 to 100cm.
Further, the stretch mode of described telescoping mechanism is mechanical, electric or hydraulic way.
The beneficial effects of the utility model are:
1, thresholding device processed in the Room is arranged on the car, makes things convenient for service personnel when the maintenance of sedan-chair top, to use at any time;
2, device is spacing reliable, can restore after the use, does not influence elevator and normally uses;
3, device is realized scalable function, can use when car position is devious, guarantees that device all can play a role in all cases.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model first embodiment;
Accompanying drawing 2 is structural representations of the utility model second embodiment.
Label in the accompanying drawing is respectively:
1. car; 2. pedestal;
3. Room door; 4. turning unit;
5. locating dowel pin; 6. telescoping mechanism;
7. sill.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model elevator reparing with Room thresholding device processed elaborated.
Referring to accompanying drawing 1, accompanying drawing 1 is first embodiment of the present utility model, elevator reparing Room thresholding device processed, comprise the pedestal 2 that is arranged on the car 1, pedestal 2 is fixedly mounted on car 1 top framework top to Room door 3, mounting rotating unit 4 on pedestal 2, turning unit 4 can rotate for hinge or other and mechanism that can be spacing, at turning unit 4 locating dowel pin 5 is installed, locating dowel pin 5 can be rotated with turning unit 4 rotating shafts, and can be fixed on some anglecs of rotation, when locating dowel pin 5 rotates to level attitude, penetrate in the Room door 3.When sedan-chair jacking row keeps in repair, when car 1 moves near the Room door 3, this moment, the sedan-chair top slightly exceeded lading door dill 7, make things convenient for the service personnel turnover, open Room door 3, will put locating dowel pin 5 and upwards be turned to horizontal direction from vertical direction, just in time withstand Room door 3, to stop Room door 3 self-closing, at this moment the service work personnel can enter sedan-chair jacking row maintenance activity.After maintenance activity finishes, locating dowel pin 5 upset is downwards returned back to vertical direction (dotted line position among the figure), make on its frame sides that is close to car 1, continue by the operation of normal running order recovery elevator.The vertical position of locating dowel pin does not influence the normal use of elevator.Can try one's best near a side of car 2 in the position of pedestal 2, at this moment can open hoistway door 3 big as far as possible, the convenient for maintaining personnel operation.The length of locating dowel pin 5 can be made as the whole width that passes Room door 3, makes spacing more reliable.
Referring to accompanying drawing 2, accompanying drawing 2 is second embodiment of the present utility model, when sedan-chair jacking row keeps in repair, if chance Room door 3 is opened the back sedan-chair and is pushed up when being positioned at the below of sill 7, the position of the locating dowel pin 5 of the device of embodiment one is below sill 7, can't realize upwards stirring to horizontality, namely can not limit the self-closing of Room door 3, present embodiment fixedly mounts telescoping mechanism 6 at pedestal 1 on the basis of embodiment one, telescoping mechanism 6 has a flexible end that can protrude upward, turning unit 4 is installed in the flexible end of telescoping mechanism 6, locating dowel pin 5 is installed on the turning unit 4, when the position that locating dowel pin 5 occurs is below sill 7, the flexible end of telescoping mechanism 6 is drawn out to the top of sill 7, the self-closing of Room door 3 limited.According to common situation, the maximum elongation amount of the flexible end of telescoping mechanism 6 is arranged to 50 to 100cm and is advisable, and the stretch mode of telescoping mechanism 6 is chosen as machinery, electric, hydraulic pressure or alternate manner.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
