Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a stable elevator door machine installation structure. Background Art
[0002] There are mainly three installation methods for elevator door machines: installation on the car frame column, installation on the door lintel, and installation on the car top. In the installation method of the car frame column, the moving parts such as the door machine and the door panel are stressed on the car column and have no connection with the enclosures and the car bottom that passengers can touch. Therefore, this installation method will not have an adverse impact on the stability of the car and is applicable to elevators with high comfort requirements. Among them, the door machine is connected to the car column through a door machine fixing bracket. Its limitation is that when the height dimension between the door machine fixing bracket and the car door is quite different, the stability of the door machine fixing bracket becomes poor, resulting in poor stability of the door machine operation, unstable process of opening and closing the car door, and potential installation hazards. For example, in a high-speed elevator, the interior height of the car is generally large, and there is a wind deflector at the top. When the door machine is installed on the car frame column, the installation position of the door machine fixing bracket will be relatively high, resulting in poor stability of the door machine operation and potential safety hazards during the use of the high-speed elevator.

[0004] The technical solution of the utility model is realized as follows: a stable elevator door machine installation structure includes a car bottom bracket, two groups of car frame columns arranged at intervals left and right on the car bottom bracket, and a door machine;
[0005] A door machine fixing bracket is provided on the front side corresponding to each group of the car frame columns;
[0006] A straight beam extending forward and backward is connected between the door machine fixing bracket and the corresponding car frame column; and a support rod extending vertically is connected between the door machine fixing bracket and the car bottom bracket;
[0007] A pull beam extending left and right is connected between the two groups of door machine fixing brackets; the door machine is fixed on the pull beam.
[0008] Furthermore, a car frame upper beam is connected between the tops of the two groups of car frame columns; the door machine fixing bracket is located below the car frame upper beam; an inclined pull rod is connected between the door machine fixing bracket and the car frame upper beam.
[0009] Further, a plurality of vertical connecting plates are arranged at intervals in the left - right direction on the tie beam; the door machine is fixedly connected to the vertical connecting plates; a horizontal connecting plate is connected between the plurality of vertical connecting plates.

[0017] The following elaborates on the preferred embodiments of the utility model in detail with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the utility model.
[0018] Such as Figure 1Shown is an installation structure of a stable elevator door machine according to this embodiment. This elevator door machine installation structure is particularly applicable to elevators where the height of the car door is significantly different from the height of the car and where high requirements are placed on the comfort of the elevator. The elevator door machine installation structure includes a car bottom bracket 1, car frame columns 2, a car frame upper beam 3, and a door machine. The car bottom bracket 1, car frame columns 2, and car frame upper beam 3 are combined to form the car skeleton of the elevator. Specifically, the car frame columns 2 are fixedly spaced left and right on the car bottom bracket 1, and the car frame upper beam 3 is connected between the tops of two groups of car frame columns 2. Among them, a door machine fixing bracket 4 is arranged on the front side corresponding to each group of car frame columns 2. A straight beam 5 extending front and back is connected between the door machine fixing bracket 4 and the corresponding car frame column 2 on that side. Through the connection of this straight beam 5, the door machine fixing bracket 4 is fixed to the car frame column 2. And a support rod 6 extending vertically is connected between the door machine fixing bracket 4 and the car bottom bracket 1. This support rod 6 can play a certain supporting role for the door machine fixing bracket 4 to improve the stability of the installation of the door machine fixing bracket 4.
[0019] A tension beam 7 extending left and right is connected between two groups of door machine fixing brackets 4. Through this tension beam 7, the two groups of door machine fixing brackets 4 are connected to form an integral structure. The aforementioned door machine 8 is fixed to the tension beam 7. The door machine 8 in this embodiment is a conventional mechanism in the elevator field and is an opening and closing device for the elevator car door.
[0020] In this embodiment, the aforementioned door machine fixing bracket 4 is located below the car frame upper beam 3. An inclined pull rod 9 is connected between the door machine fixing bracket 4 and the car frame upper beam 3. This inclined pull rod 9 has two ends in the front-back direction to be able to form a pulling effect on the door machine fixing bracket 4 and further improve the stability of the installation of the door machine fixing bracket 4.
[0021] A number of vertical connecting plates 71 are arranged at intervals in the left-right direction on the aforementioned tension beam 7. The door machine 8 is fixedly connected to the vertical connecting plates 71. A horizontal connecting plate 72 is connected between a number of vertical connecting plates 71. Through the connection of this horizontal connecting plate 72, a number of vertical connecting plates 71 are connected to form an integral structure to improve the connection strength of the door machine.
[0022] During specific installation, there is an overlapping position in the up-down direction between the above-mentioned door machine 8 and the tension beam 7. Through this tension beam 7, the gap between the door machine 8 and the elevator car door lintel can be blocked, reducing the wind noise during high-speed operation of the elevator.
[0023] During actual use, when installing the door machine fixing bracket 4, the straight beam 5 and the support rod 6 can effectively support and fix the door machine fixing bracket 4, so as to improve the stability of the connection and fixation of the door machine fixing bracket 4. The door machine 8 is fixed on the door machine fixing bracket 4 through the tension beam 7. By the above method, the stability of the operation of the door machine 8 can be effectively improved. The main force after the installation of the door machine 8 is on the car frame column 2, which will not affect the center of gravity and comfort of the car, and is applicable to the assembly requirements of elevators with a large height difference between the door machine fixing bracket 4 and the car door and high requirements for elevator comfort. Through the pulling of the diagonal tension rod 9, the door machine fixing bracket 4 can be further supported, effectively improving the stability of the installation and fixation of the door machine fixing bracket 4.
[0024] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
