Description

Anticreep hoistway door

Technical field

The utility model relates to mechanical equipment technical fields, and in particular to a kind of hoistway door.

Background technique

The hall door of elevator is caused to will lead to hall door disengaging by abnormal external force collision and initiation falls terraced accident, therefore country is to the Room The anticollision of door requires have certain technical specification, and current each manufacturer has reached this specification.But specification only requires The door-plate of hall door is subjected to after swing ball hits, the deflection of door-plate, and a possibility that do not consider secondary impact or bigger shock.

Famous brand name has some corresponded manners higher than national standard, general manufacturer only steel plate do it is thick a little and , national standard is basic demand.

Present hoistway door bottom relies solely on the anti-off board on guide groove and hall door on sill and carries out stress.Its In, anti-off board be it is straight, after being hit, it is difficult to resist secondary impact or bigger shock.In addition, if anti-off board On guide shoe abrasion, the anticollision that will affect hall door is horizontal.

Utility model content

The purpose of the utility model is to provide a kind of anticreep hoistway doors, solve at least one above technical problem.

The technical issues of the utility model is solved can be realized using following technical scheme:

Anticreep hoistway door, the hall door including elevator and the sill below the hall door, with the length of the sill Direction is spent as left and right directions, and the bottom of the hall door is equipped at least one piece of anti-off board, the anti-off board and is embedded in the sill In guide groove, the bottom of the anti-off board is forwards or rear is bent to form mousing-hook,

Along the left and right directions of the sill, the upper end of side wall close to the mousing-hook side of the guide groove is equipped with convex The separation prevention bar risen；

The bottom of the hall door is additionally provided with the guide shoe for guiding the hall door glide direction, and the guide shoe is embedded in the guide groove In, the front and rear sides of the guide shoe are respectively held against the side wall of the separation prevention bar and the guide groove.

The utility model by anti-off board be arranged mousing-hook, corresponding separation prevention bar is set in the guide groove of sill, When hall door is by hitting, this mousing-hook can be hooked in the separation prevention bar of sill, and anti-off board will not deviate from out of guide groove, from And hall door is made to can continue to resist secondary impact that may be present or bigger shock, it prevents hall door from falling off and causes safe thing Therefore.Meanwhile guide shoe plays the role of positioning and guiding, keeps hall door more steady in sliding.

Optionally, the inside of the mousing-hook is equipped with several along triangle reinforcing rib in the front-back direction.

Mousing-hook is equipped with reinforcing rib, improves the intensity of mousing-hook, is unlikely to deform mousing-hook after bearing to hit.

Optionally, any one side of the anti-off board is equipped with bar shaped reinforcing rib along vertical direction.

Anti-off board is equipped with reinforcing rib, enhances the ability of anti-deformation of anti-off board.

Optionally, the length of the mousing-hook in the longitudinal direction is 4~8mm.

Optimize the size of mousing-hook, if size is too short, mousing-hook may be hooked less than separation prevention bar, can if size is too long Increase the installation difficulty of anti-off board.

As a preferred embodiment, the guide shoe includes at least one plate body and is set in each plate body lower end Rubber sleeve, the upper end of the plate body is bolted on the bottom of the hall door；

The anti-off board is arranged between the guide shoe.

Further, the front and rear sides surface of the guide shoe is equipped with the strip groove along left and right directions.

To reduce the frictional force between guide shoe and sill slot, abrasion is reduced.

As another preferred embodiment, the guide shoe is guide shoe made of a rubber, and the guide shoe is equipped with for described anti- The through-hole that de- plate passes through, the front and rear sides of the guide shoe are respectively held against the side wall of the separation prevention bar and the guide groove.

Guide shoe is rubber material, has elasticity, is easily installed.

Further, carbon fiber layer or polytetrafluoroethylene ethylene layer are covered on the inside of the through-hole.Carbon fiber layer and polytetrafluoroethylene (PTFE) Layer has high-intensitive, self-lubricating characteristic, can effectively slow down the abrasion of guide shoe caused by elevator longtime running, without be used in through-hole with Lubricant is added on the contact surface of anti-off board.
