There are also step-type ones, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. A fixed lifting device that serves specified floors. A vertical lift has a car that runs between at least two rows of rigid rails that are perpendicular or inclined at an angle of less than 15°.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figure 1-3 The utility model provides an embodiment: a thickened steel plate for the main beam of the elevator room floor, including a main steel beam 1, a total of two main steel beams 1, the two main steel beams 1 are symmetrically arranged, and a transverse steel beam 2 is fixedly installed between the two ends of the two main steel beams 1 by welding. The main steel beam 1 and the transverse steel beam 2 are both I-shaped steel beams. The two main steel beams 1 and the two transverse steel beams 2 are designed in a square structure and together constitute a thickened steel plate, as shown in the attached specification. Figure 1 As shown;

[0022] In particular, during specific use, the lengths of the main steel beam 1 and the transverse steel beam 2 can be dynamically selected according to the floor area of ​​the elevator room, that is, the size of the square structure formed by the main steel beam 1 and the transverse steel beam 2 is adapted to the internal floor area of ​​the elevator room, so that the square thickened steel plate formed by the main steel beam 1 and the transverse steel beam 2 can contact the four walls of the elevator room respectively;

[0023] A number of equally spaced linearly distributed triangular reinforcement ribs 5 are installed in the side grooves of the main steel beam 1 and the transverse steel beam 2. The number of triangular reinforcement ribs 5 on each side is not less than five. The triangular reinforcement ribs 5 can effectively improve the overall structural strength of the main steel beam 1 and the transverse steel beam 2, so that they have greater impact resistance, effectively improve the use effect and structural stability, and prevent deformation.

[0024] In this embodiment, the upper and lower horizontal planes of the main steel beam 1 and the transverse steel beam 2 are flush with each other, that is, the thickness of the main steel beam 1 and the transverse steel beam 2 are the same, and the thickness of the main steel beam 1 and the transverse steel beam 2 is between 18-22 mm. Therefore, when the thickness of the concrete in the machine room is relatively thin, the stability of the motor host during operation can be effectively improved by adding a certain thickness of thickened steel plate.

[0025] In this embodiment, in order to facilitate the installation of the thickened steel plate of the main beam of the utility model on the wall of the elevator machine room, upper mounting seats 3 are fixedly installed at both ends of the upper surface of the two main steel beams 1. The upper mounting seat 3 adopts an "L"-shaped structural design, and the upper mounting seat 3 is provided with mounting holes 4 for wall fixing. The "L"-shaped upper mounting seat 3 and the mounting holes 4 can be matched with the wall surface of the machine room wall, thereby completing the overall installation of the thickened steel plate.

[0026] In this embodiment, lower mounting plates 6 are fixedly mounted on both ends of the lower surfaces of the two main steel beams 1;

[0027] Furthermore, a spring damping rod 7 is fixedly mounted on the lower surface of each lower mounting plate 6, a buffer spring 8 is sleeved on the outside of the spring damping rod 7, and the top end of the buffer spring 8 is fixedly connected to the main steel beam 1;

[0028] With this structural design, during installation, the bottom end of the buffer spring 8 contacts the floor of the elevator room, and the overall installation of the thickened steel plate is completed through the upper mounting seat 3. When the buffer spring 8 and the spring damping rod 7 are actually used, when the mounting hole 4 of the upper mounting seat 3 becomes loose or falls off, the external impact force will act on the buffer spring 8 and the spring damping rod 7 through the main steel beam 1, so that the compressed buffer spring 8 and the spring damping rod 7 can be used as a force buffering structure, thereby effectively absorbing and buffering external forces, so that it has certain buffering protection characteristics, better guarantees the operation effect of the room, and improves safety in use.

[0029] Working principle: When the utility model is actually used, two main steel beams 1 and two transverse steel beams 2 are prepared, and Figure 1 The steel plate is welded and fixed in the state shown to form a square thickened steel plate structure;

[0030] It should be noted that, in actual use, the length of the main steel beam 1 and the transverse steel beam 2 can be dynamically selected and adjusted according to the floor area of ​​the elevator room. The basic requirement is that the square structure size formed by the welding of the main steel beam 1 and the transverse steel beam 2 is adapted to the internal floor area of ​​the elevator room, that is, the square thickened steel plate formed by the main steel beam 1 and the transverse steel beam 2 can be in contact with the four walls of the elevator room respectively;

[0031] After the above work is completed, the square thickened steel plate is laid on the floor of the elevator room, so that the buffer spring 8 and the spring damping rod 7 are in contact with the ground. At this time, the upper mounting seats 3 at the four corners are in contact with the four walls of the elevator, and the installation of the thickened steel plate is completed through the mounting holes 4 and the expansion bolts;

[0032] The utility model is suitable for installation and use in elevator machine rooms with thin concrete floors. When the concrete thickness of the machine room is thin, the installation of the utility model with a certain thickness of thickened steel plate can effectively improve the stability of the motor host during operation, improve the overall structural strength of the concrete machine room, and improve the performance;

[0033] The utility model installs a plurality of equally spaced linearly distributed triangular reinforcing ribs 5 in the side grooves of the main steel beam 1 and the transverse steel beam 2. The triangular reinforcing ribs 5 can effectively improve the overall structural strength of the main steel beam 1 and the transverse steel beam 2, so that the main steel beam 1 and the transverse steel beam 2 have greater impact resistance, effectively improve the use effect and structural stability, and prevent deformation.

[0034] When the buffer spring 8 and the spring damping rod 7 are actually used, when the mounting hole 4 of the upper mounting seat 3 becomes loose or falls off, the external impact force will act on the buffer spring 8 and the spring damping rod 7 through the main steel beam 1. The compressed buffer spring 8 and the spring damping rod 7 can be used as a force buffering structure, thereby effectively absorbing and buffering the external force, so that it has certain buffering protection characteristics, better guarantees the operation effect of the machine room, and improves the safety of use.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
