Assembly for stably installing ground sill

Abstract

The assembly comprises an elevator shaft and the ground sill arranged on one side of the elevator shaft, an installation bracket is installed on the surface of the elevator shaft, the ground sill is installed on one side of the installation bracket, a plurality of supporting pieces are installed on the other side of the installation bracket, and one side of each supporting piece is connected to the elevator shaft. The sliding blocks of the elevator door can pass through the gap areas among the supporting pieces when passing through the sliding grooves in the surface of the ground sill, deformation of the ground sill can be reduced when passing through the gap areas due to the fact that the installation bracket is stressed preferentially, and the installation bracket is installed between the ground sill and the elevator shaft. And the mounting bracket is mounted on the inner side surface of the elevator shaft in a larger area, and the matching between the mounting bracket and the ground sill is enhanced by the supporting piece, so that the mounting bracket can prevent the position of the ground sill from shifting, and the stability and the safety of the elevator in use are greatly enhanced.

Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a component for stably installing a floor sill. Background Art

[0002] Due to the current shortage of land resources, all kinds of newly built buildings are built high up. In order to facilitate people's lives and production, many elevators are usually installed in such buildings. However, such buildings are basically cast-in-place frame structures. During the construction process, corbels are basically not added to a certain section of the ring beam specifically for the elevator. Therefore, the elevator shaft is basically without corbels. For small-tonnage elevators, the weight of the goods entering and exiting the elevator will not be too large, and the force acting on the floor door sill will not be large. The conventional corbel-free floor door sill can fully ensure the normal operation of the elevator.

[0003] The authorization announcement number is CN211812948U, which discloses an elevator door panel with comprehensive performance. Combined with its specification and drawings, if this elevator door panel is installed on an elevator with large tonnage, the conventional corbel-free floor door sill is not enough. After a long period of operation, a large gap may appear between the sill and the building, causing the sill to deviate from its original position, and the door slider cannot slide normally in the sill groove, causing the elevator to malfunction; there is also a situation where the wheel just passes through the gap between the sill support feet, causing the sill to deform. Summary of the invention

[0004] The utility model mainly aims at the problems existing in the installation of the above-mentioned floor sills, and invents a component for stably installing the floor sills. When the slider of the elevator door passes through the slide groove on the surface of the floor sill, it will pass through the gap area between a number of support members. When passing through the gap area, the mounting bracket is subjected to the priority force, so the deformation of the floor sill can be reduced. Moreover, since the mounting bracket is installed between the floor sill and the elevator shaft, and the mounting bracket is installed on the inner surface of the elevator shaft with a larger area, the cooperation between the mounting bracket and the floor sill is also strengthened due to the support members, so the mounting bracket can avoid the displacement of the position of the floor sill.

[0005] The invention objective of the utility model is achieved through the following technical scheme: a component for stably installing a floor sill, comprising an elevator shaft, a floor sill arranged on one side of the elevator shaft, a mounting bracket installed on the surface of the elevator shaft, a floor sill installed on one side of the mounting bracket, and a plurality of supporting members installed on the other side of the mounting bracket, and one side of each of the supporting members is connected to the elevator shaft.

[0006] Preferably, a plurality of first mounting holes are provided on the surface of the mounting bracket, and the interior of the first mounting holes is connected to the surface of the elevator shaft through chemical anchor bolts.

[0007] Preferably, a first mounting groove is provided at the bottom of the floor sill, a plurality of second mounting holes are provided on the surface of the mounting bracket, a third mounting hole is provided on the surface of the support member, and first fixing bolts are installed inside the first mounting groove, the second mounting hole and the third mounting hole.

[0008] Preferably, a recessed surface is provided downwardly on one side of the mounting bracket, the floor sill is connected to the surface of the recessed surface, a second mounting groove is provided on the side wall of the floor sill, and the second mounting groove is connected to the mounting bracket via a second fixing bolt.

[0009] Preferably, the cross-section of the support member is L-shaped, and the side wall of the support member is provided with a fourth mounting hole, and the interior of the fourth mounting hole is connected to the side wall of the elevator shaft through a collision bolt.

[0010] Preferably, a plurality of slide grooves are provided on the surface of the floor sill, and sliders of the elevator door are slidably installed inside the slide grooves.

[0011] Preferably, the length of the floor sill is greater than the length of the mounting bracket, and this arrangement is for the elevator door to work normally.

[0012] Compared with the prior art, the utility model has the following beneficial effects: 1. When the slider of the elevator door passes through the slide groove on the surface of the floor sill, it will pass through the gap area between several supporting members. When passing through the gap area, the deformation of the floor sill can be reduced due to the priority force of the mounting bracket. Moreover, since the mounting bracket is installed between the floor sill and the elevator shaft, and the mounting bracket is installed on the inner surface of the elevator shaft with a larger area, the fit between the mounting bracket and the floor sill is also strengthened due to the supporting members. Therefore, the mounting bracket can avoid the displacement of the position of the floor sill, which greatly enhances the stability and safety of the elevator when in use. 2. The space required for the entire mounting structure is not significantly changed compared with the overall mounting structure of the traditional floor door, and the added accessories are relatively cheap, so the overall increased cost during the installation process is also relatively low.
