Abstract

The elevator movable sill comprises a bracket, a sill main body and a buffer component, wherein the bracket is used for being installed and fixed below an elevator door, the sill main body can be installed above the bracket in a reciprocating manner along a first direction, a sliding groove extending along a second direction is formed in the sill main body and is used for enabling the lower end of the elevator door to slide in the running direction of a switch door, the second direction is perpendicular to the first direction, a long groove hole extending along the first direction is formed in the top of the bracket, a sill supporting leg downwards penetrating into the long groove hole is formed in the bottom of the sill main body, the sill supporting leg can move in a reciprocating manner along the long groove hole, and the buffer component is installed between the sill supporting leg and the bracket and is used for providing elastic force for resetting after the sill main body moves. Therefore, the elevator car door or the landing door can be buffered by the movement of the sill main body, and the elevator car door or the landing door can be effectively prevented from being deformed. The invention has obvious anti-collision effect, no need of complex structure and low installation and transformation cost.

Description

Movable sill of elevator and elevator Technical Field The invention relates to the technical field of elevators, in particular to an elevator movable sill and an elevator. Background The elevator sill is generally arranged below the elevator door, a sliding groove of the sill is used for sliding a sliding block at the lower end of the elevator door in the running direction of the opening and closing door, the function of fixing the running track of the elevator door is achieved, and the elevator sill can be divided into a car door sill and a landing door sill. The installation of traditional goods lift sedan-chair door sill and elevator car is fixed structure, and easy striking (like the shallow by force in the door opening process) takes place when frequently advancing such as goods shallow, and the impact force directly is born by the door body, frequently bumps and easily leads to the door body to warp the damage, and then can arouse elevator trouble, produces the potential safety hazard. In the scheme of a high-strength anti-collision elevator door disclosed in Chinese patent CN 217398197U, the upper end of a door plate is hinged with a hanging plate, and the door plate is matched with a buffer assembly positioned between the lower end of the door plate and a sill, so that when the elevator door is impacted, the door plate can swing around a hinge point in a small range, and the impact force borne by the elevator door can be effectively relieved by a door plate sliding block through the buffer assembly. But this scheme structure is comparatively complicated, needs to reform transform the design to door plant upper and lower extreme, and periodic maintenance inspection is also comparatively complicated difficult. There is also an anti-deformation elevator sill disclosed in chinese patent CN 117963683A and a preparation process thereof, the scheme sets a compression-resistant body at the top of the fixed sill, and an anti-collision plate and an elastic member are arranged inside the elevator sill, so that the anti-deformation capability of the sill during vertical compression can be mainly prevented, and the pressure brought by sliding of an elevator door can be simply relieved. However, in this scheme, when the door body receives the level and hits, its lower extreme movable range still is limited in the sill spout, and the buffer effect of crashproof board is relatively poor. Disclosure of Invention The invention aims to provide the movable sill of the elevator, which can effectively protect the door body and reduce the deformation of the door body, and has the advantages of simple structure, convenient maintenance, good buffering effect and high use safety. Another object of the invention is to provide an elevator with the advantages of high reliability and low failure rate. In order to achieve the above object, the solution of the present invention is: The elevator movable sill comprises a bracket, a sill main body and a buffer component; the bracket is used for being installed and fixed below the elevator door; the elevator sill comprises a sill main body, a bracket, a sliding block, a door opening and closing mechanism and a door opening and closing mechanism, wherein the sill main body can be mounted above the bracket in a reciprocating manner along a first direction; the top of the bracket is provided with a long slot hole extending along a first direction, the bottom of the sill main body is provided with a sill support leg penetrating downwards into the long slot hole, and the sill support leg can reciprocate along the long slot hole; The buffer component is arranged between the sill support leg and the bracket and is used for providing elastic force for resetting the sill body after moving. Further, the buffer component is a spring, a shrapnel, a tension spring or rubber. The elevator door is a car door or a landing door, the bracket comprises an upper mounting plate and a side connecting plate which are mutually and vertically connected, the side connecting plate is vertically arranged and is laterally attached to and mounted on a car bottom plate or a floor, the upper mounting plate is horizontally arranged and is positioned at the top of the side connecting plate, the upper mounting plate is connected with the sill main body in a sliding manner and is provided with the long slot holes, and a plurality of triangular stiffening plates which are arranged at intervals along the second direction are further arranged between the upper mounting plate and the side connecting plate.
