Abstract
The invention discloses a device and a method for reducing a gap between a hoistway door sill and a lift car door sill. The device comprises a first lift car door sash and a second lift car door sash which are arranged at the entrance-exit of a lift car, and a baffle plate for reducing the gap between the lift car door sill on the lower part of the entrance-exit of the lift car and the hoistway door sill on the lower part of a landing entrance-exit, wherein a door vane is arranged on the first lift car door sash or a first hanging plate which is connected with the first lift car door sash; and the baffle plate is arranged on the front side of the lift car door sill and connected with the first lift car door sash or the second lift car door sash, and can be driven by the first lift car door sash or the second lift car door sash to move to and fro between a first position and a second position in the length direction of the lift car door sill. The baffle plate is driven by the opening and closing motion of the lift car door sashes to move along the length direction of the lift car door sill; when a lift car door is opened, the gap between the lift car door sill and the hoistway door sill can be reduced; and when closed, the lift car door can keep away from the roller of the door lock of a hoistway door. The device has the advantages of simple structure and low cost.
Description
Technical field
The present invention relates to the elevator technology field, especially a kind of device that is used to reduce hoistway door sill and car door sill gap, and a kind of method that reduces hoistway door sill and car door sill gap.
Background technology
At present in the elevator industry, for guaranteeing the safety distance of the normal operation of elevator, gap between lading door dill and the car door sill needs about 30mm usually, because this gap is bigger, when leading to herein, the passenger is easy to generate unsafe sensation, and cause foreign matter to fall into hoistway easily from this gap, cause the damage of associated components.The existing mode that reduces the landing sill gap mainly contains following two kinds:
One, fixed type gap blocker structure.As shown in Figure 1, at two sections car door sill link stoppers 18 of car door sill 4 upward swing door width L scope internal fixation, itself and car door sill 4 adopts alternate manner such as bolts to fix, under gate closing back door cutter, block is not set for avoiding every lock roller position, the Room, and lading door dill block 19 is set at cooresponding every layer of entrance hall gate sill 9 place; When Elevator landing was stopped, the car door sill link stopper of car door sill 4 18 was used with lading door dill block 19 on the lading door dill 9 and has reduced the gap of lading door dill 9 with car door sill 4.The method weak point is, needs two sections car door sill blocks 18 of design on car door sill 4, and whenever on the door one section lading door dill block 19 need be set also layer by layer, and cost is higher.And since at the lading door dill block 19 on the lading door dill 9 under the door roller of the Room, when elevator has a power failure, lading door dill block 19 might just in time be stuck in the centre of a cutter 1, cause directly to open the gate rescue, can only move by jiggering and just can open gate after car is avoided gate door cutter and block, rescue very inconvenient.
Its two, Chinese patent 200780052012.7 disclosed rotary block structures.It pivots by block and seals gap between lading door dill and the car door sill, but it can not allow block flush with sill, influences attractive in appearancely, and realizes that mechanism is comparatively complicated, thereby the cost height.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of device that is used to reduce hoistway door sill and car door sill gap is provided, it is simple in structure, and cost is low.
The device that is used to reduce hoistway door sill and car door sill gap of the present invention, comprise the first car door leaf and the second car door leaf of being located at the car gangway, and the baffle plate that is used to reduce gap between the lading door dill of the car door sill of bottom, car gangway and landing doorway bottom, on the described first car door leaf or with the described first car door leaf bonded assembly, first link plate on be provided with a cutter, it is characterized in that: described baffle plate is located at the front side of described car door sill, and be connected with described first car door leaf or the described second car door leaf, this baffle plate can move around between the primary importance and the second place at the length direction of the described car door sill in drive lower edge of described first car door leaf or the described second car door leaf; When described primary importance, described first car door leaf and the described second car door leaf are opened, described baffle plate traverses described first car door leaf and the pairing described gap of the described second car door leaf door opening width, and when the described second place, described first car door leaf and the described second car door leaf are closed, and described baffle plate is positioned at a side of the close described second car door leaf of described door cutter vertical projection.
As the preferred embodiment of technique scheme, between described car door sill and described baffle plate, be provided with guide chute and the guide that matches.
As the preferred embodiment of technique scheme, the length of described baffle plate is equal to or greater than the width of described car gangway.
As the preferred embodiment of technique scheme, when described first car door leaf and the described second car door leaf were closed, the distance of described baffle plate and described door cutter vertical projection was greater than 7mm.
As the preferred embodiment of technique scheme, the spacing between described baffle plate and the described car door sill is greater than 2mm, and the spacing between described baffle plate and the described lading door dill is greater than 7mm.
As the preferred embodiment of technique scheme, the sense of motion of described first car door leaf and the described second car door leaf is opposite; Described baffle plate is captiveed joint with the described first car door leaf.
Preferred embodiment as technique scheme, described baffle plate is connected with the described second car door leaf through link gear, this link gear comprises second link plate that is installed in described second car door leaf upper end, is located at this second link plate both sides and be located at the fixed pulley of both sides of described baffle length direction and steel rope or the belt on this fixed pulley respectively respectively, and described baffle plate is all captiveed joint with described steel rope or belt with described second link plate.
The method that is used to reduce hoistway door sill and car door sill gap of the present invention, the device that being used to of its application reduces hoistway door sill and car door sill gap comprises the first car door leaf and the second car door leaf of being located at the car gangway, and the baffle plate that is used to reduce gap between the lading door dill of the car door sill of bottom, car gangway and landing doorway bottom, on the described first car door leaf or with the described first car door leaf bonded assembly, first link plate on be provided with a cutter, it is characterized in that: described baffle plate is located at the front side of described car door sill, and be connected with described first car door leaf or the described second car door leaf, this baffle plate can move around between the primary importance and the second place at the length direction of the described car door sill in drive lower edge of described first car door leaf or the described second car door leaf; When described primary importance, described first car door leaf and the described second car door leaf are opened, described baffle plate traverses described first car door leaf and the pairing described gap of the described second car door leaf door opening width, and when the described second place, described first car door leaf and the described second car door leaf are closed, and described baffle plate is positioned at a side of the close described second car door leaf of described door cutter vertical projection.
