Description

Elevator car wallboard preventing reinforcing ribs from falling off

Technical Field

The utility model relates to an elevator technical field, especially an elevator car wallboard that prevents strengthening rib and drop.

Background

The car of the elevator is formed by splicing a block of elevator car wall plate, in order to ensure the strength of the elevator car wall plate, reinforcing ribs need to be arranged on the back surface of the elevator car wall plate, the thickness of a steel plate of the existing elevator car wall plate is generally 1.0mm-1.5mm, if the reinforcing ribs are welded on the back surface, the decorative surface of the elevator car wall plate is blackened, and the attractiveness of the car is seriously influenced, therefore, the reinforcing ribs on the back surface of the existing elevator car wall plate are fixed in a bonding mode, but the bonding has a great defect, namely, the bonding agent is aged along with the lengthening of the service time, and the bonding firmness is influenced by the vibration during the operation of the elevator car, so that the phenomenon that the reinforcing ribs on the back surface of the elevator car wall plate fall off begins to appear along with the increase of the service life of the elevator, the fallen reinforcing ribs directly fall into a hoistway to smash other elevator components, the life threat to the maintenance personnel is formed;

in order to solve the problems, people consider that the two ends of the reinforcing rib are directly fixed on the back turned edges of the upper and lower bending parts of the elevator car wallboard through the bolts, but the practical application finds that the two ends of the reinforcing rib can generate large stress on the back turned edges of the upper and lower bending parts of the elevator car wallboard through the bolts, so that the reinforcing rib is not firmly bonded, and the reinforcing rib is accelerated to fall off, and when the height of the elevator car wallboard is higher, the stress can also enable the elevator car wallboard to generate large deformation, therefore, the elevator car wallboard which prevents the reinforcing rib from falling off under the premise of not influencing the existing reinforcing rib bonding is urgently needed.

SUMMERY OF THE UTILITY MODEL

In order to prevent it from droing under the prerequisite that does not influence current strengthening rib bonding, the utility model provides a prevent elevator car wallboard that strengthening rib drops, square hole has been seted up respectively at both ends about the strengthening rib, insert the one end of anticreep support in the square hole, the other end is fixed on the back turn-ups of department of bending about elevator car wallboard, when the strengthening rib drops because of the bonding agent is ageing, the anticreep support catches the strengthening rib to can also prevent it from droing under the prerequisite that does not influence current strengthening rib bonding, the emergence of dangerous accident has been avoided.

The technical scheme of the utility model is that: an elevator car wallboard for preventing reinforcing ribs from falling off comprises: the elevator car comprises an elevator car wall plate, a reinforcing rib, an anti-falling support and a connecting bolt; the method is characterized in that: the elevator car wallboard is bent the preparation by corrosion resistant plate through the four sides and is formed, the length of strengthening rib does the length of elevator car wallboard subtracts 20mm after subtracting the turn-ups width in the department of bending back from top to bottom, the strengthening rib passes through the adhesive and bonds in the back of elevator car wallboard, the strengthening rib is nearly style of calligraphy, is at the distance strengthening rib one end inserts in the square hole of strengthening rib, the other end of anticreep support passes through connecting bolt to be fixed on the back turn-ups of department of bending from top to bottom of elevator car wallboard, work as when the strengthening rib drops because of the adhesive is ageing, the anticreep support catches the strengthening rib prevents that it from falling into in the elevator well on the elevator car wallboard.

Further, the connecting hole that is connected the usefulness with adjacent elevator car wallboard is seted up to the department of bending in elevator car wallboard side, the connecting hole that is connected with elevator ceiling is seted up to the department of bending above the elevator car wallboard, the connecting hole that is connected with the elevator bottom plate is seted up to the department of bending below the elevator car wallboard.

Further, when the width of elevator car wallboard is greater than 300mm and when being less than or equal to 500mm the back of elevator car wallboard bonds one the strengthening rib, works as when the width of elevator car wallboard is greater than 500mm and when being less than or equal to 650mm the back of elevator car wallboard bonds two the strengthening rib works as when the width of elevator car wallboard is greater than 650mm and when being less than or equal to 700mm the back of elevator car wallboard bonds three the strengthening rib.

Furthermore, the whole anti-drop support is in a hook shape, the middle of one end of the anti-drop support is in a bracket hook shape, and the other end of the anti-drop support is provided with a bolt connecting hole.

Furthermore, the bolt connecting hole of the anti-falling support is arranged in the middle of the other end of the anti-falling support.

The beneficial effects of the utility model reside in that: the utility model discloses both ends have seted up square hole respectively about the strengthening rib, insert the one end of anticreep support in the square hole, the other end is fixed on the back turn-over of the department of bending about the elevator car wallboard, when the strengthening rib does not drop, the anticreep support does not have any contact with the strengthening rib, can not influence the effect that current strengthening rib bonded, when the strengthening rib drops because of the bonding agent is ageing, the anticreep support catches the strengthening rib, thereby can also prevent it and drop under the prerequisite that does not influence current strengthening rib bonding, the emergence of dangerous accident has been avoided.
