Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below with reference to the technical solutions of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that in the following embodiments, the elevator door includes a landing door and a car door.
An elevator door sill comprises more than two rectangular tubes 1 arranged side by side and reinforcing plates 2 which are positioned at two ends of each rectangular tube 1 and connected with the end parts of the rectangular tubes 1 at the same side; the bottom of the rectangular tube 1 is provided with a backing plate 3.
The tip of homonymy at each rectangular pipe 1 passes through reinforcing plate 2 and welds even, passes through backing plate 3 at the bottom and welds even with each rectangular pipe 1, constitutes integrative with the structural strength who strengthens the sill. The gaps between the rectangular tubes 1 form guide channels for the doors to slide laterally within the guide channels. The number of the guide grooves of the sills can be changed by increasing or decreasing the number of the rectangular pipes 1, for example, when two rectangular pipes 1 exist, the guide grooves between the sills are single grooves; when three rectangular pipes 1 are arranged, the guide grooves between the sills are double grooves; similarly, the guide slots between the sills of the number of the rectangular tubes 1 are increased to form a plurality of grooves, so that the elevator car sill can be suitable for car doors and landing doors of different specifications. In addition, the connecting position of the backing plate 3 and the rectangular tube 1 is changed, for example, the backing plate 3 is connected to the left side of the bottom of the rectangular tube 1, and the elevator can be used as a sill of a left-opening elevator; the base plate 3 is connected to the right side of the bottom of the rectangular tube 1 and can be used as a sill of a right-opening elevator; when the base plate 3 is connected to the middle part of the rectangular tube 1, the elevator can be used as a sill of a center-split elevator.
In the present embodiment, the rectangular tube 1, the reinforcing plate 2 and the backing plate 3 are made of metal, and the rectangular tube 1 may be a hollow tube to reduce weight. Rectangular pipe 1 passes through welded connection with reinforcing plate 2, backing plate 3 and rectangular pipe 1's bottom welded connection. The base plate 3 is arranged in the middle of the rectangular pipe 1 and used as a sill of the center-split elevator; as shown in fig. 1, 3 rectangular tubes 1 are double-groove guide grooves; as shown in FIG. 3, there are 2 rectangular tubes 1, which are single-groove guide grooves.
Further, as shown in fig. 2, the base plate 3 includes a horizontal plate 4 and a vertical plate 5 located on one side of the horizontal plate 4, and the vertical plate 5 is provided with a mounting hole 6 for a toe guard 11.
In the embodiment, the backing plate 3 is a bent piece of steel plate, and is formed by bending a vertical plate and a transverse plate 4 which are integrally connected. The toe guard 11 mounting hole 6 on the vertical plate 5 is used for mounting the toe guard 11. Toe guards 11 are typically installed under the sill of the elevator landing doors and car doors to prevent elevator passengers from getting in and out of the elevator with their feet stuck in the hoistway causing shearing injury when the elevator is not completely flat or the car sill surface is below or above the landing sill.
Further, as shown in fig. 1 and 2, a plurality of groups of strip-shaped holes 7 corresponding to the positions of the rectangular tubes 1 are distributed on the transverse plate 4.
The bar hole 7 is a welding hole, and is positioned on the transverse plate 4 below each rectangular tube 1, and is used for welding the bottom of the base plate 3 and the bottom of the rectangular tube 1, so that the elevator door is prevented from sliding in the guide groove due to the influence of welding in the guide groove. In addition, the design of the multiple groups of strip-shaped holes 7 can weld the backing plate 3 on the left side, the right side or the middle part of the bottom of the rectangular pipe 1 according to the requirements of elevators with different specifications so as to serve as sills of a left-opening elevator, a right-opening elevator and a middle-opening elevator respectively. In the prior art, the sill manufactured by bending the steel plate, planing the aluminum alloy and casting iron is often formed in one step, and different processing workpieces or tools are needed for elevators with different specifications. The manufacturing process is simple and flexible in the production process, and the production cost is reduced while the structural strength of the sill is ensured.
Further, as shown in fig. 3, dust passing holes 8 are formed in the horizontal plate 4 of the backing plate 3.
In the sliding and opening process of the elevator door, the dust passing hole 8 is used for discharging dust or sundries falling into the guide groove between the rectangular pipes 1 so as to avoid influencing the normal sliding of the landing door or the car door on the guide groove.
Further, as shown in fig. 4, the rectangular tube 1 is provided with a door pocket attachment hole 9 on the side opposite to the riser 5.
The door pocket can be a door pocket of a landing door or a car door, and the rectangular pipe 1 is fixedly connected with the door pocket at the position of the door pocket connecting hole 9 through a bolt.
Further, as shown in fig. 1, the bottom of the backing plate 3 is provided with a connecting member 10.
In this embodiment, connecting piece 10 is the C type piece of bending, and the C type piece has the high characteristics of structural strength for connect sill and well steel corbel or civil engineering corbel, in this embodiment, bend the piece and be connected with steel corbel or civil engineering corbel with the C type through the rhombus screw.
The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above description is only a specific implementation method of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions and improvements made within the spirit of the present invention should be included in the protection scope of the present invention.
