DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it 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 indirectly connected 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.
[0022] Example:
[0023] like Figure 1-Figure 4 As shown, a compact household ladder includes a traction system 2, a car 3 and a counterweight 4 arranged in a hoistway 1. A U-shaped guide rail bracket 5 is provided on the counterweight 4 side of the hoistway 1. The counterweight 4 is located in a space surrounded by the guide rail bracket 5 and the hoistway 1. The middle part of the guide rail bracket 5 is bent toward the counterweight 4 to form a notch 53 on the car 3 side. A first car guide rail 54 is provided at the notch 53. A second car guide rail 56 is provided on the car 3 side of the hoistway 1. The first car guide rail 54 and the second car guide rail 56 are axially symmetrically distributed.
[0024] The utility model designs a notch 53 shape on the guide rail bracket 5 on the side of the counterweight 4, and arranges a first car guide rail 54 at the notch 53. A second car guide rail 56 corresponding to the first car guide rail 54 is arranged on the side of the car 3 of the hoistway 1. The car 3 is allowed to slide up and down through the first car guide rail 54 and the second car guide rail 56, thereby increasing the guide rail spacing on both sides of the car 3, increasing the width of the car 3, saving the space of the hoistway 1, and improving the utilization rate of the hoistway 1 of the home elevator.
[0025] The guide rail bracket 5 includes a side beam 51 and fixed beams 52 at both ends of the side beam 51 . The fixed beam 52 is connected to the shaft 1 . The notch 53 is located on the side beam 51 . The fixed beam 52 is provided with a counterweight guide rail 55 toward the counterweight 4 .
[0026] The guide rail bracket 5 arranged on the side of the shaft counterweight 4 can be used to install the car guide rail and the counterweight guide rail 55. It has multiple uses, a compact structure, saves space and material costs, and improves the space utilization of the shaft 1.
[0027] The counterweight 4 is provided with an avoidance groove 41 corresponding to the notch 53 on the side facing the car 3 .
[0028] The fixed beam 52 is connected to the shaft 1 via a reinforcing plate 57. The design of the reinforcing plate 57 improves the installation stability of the guide rail bracket 5.
[0029] The traction system 2 includes a traction machine 21 and a steel belt 22. A frame 23 is provided above the car 3. The traction machine 21 is mounted on the frame 23. The steel belt 22 is wound on the traction machine 21. One end of the steel belt 22 is connected to the counterweight 4. The other end of the steel belt 22 is connected to the car 3 by passing around the guide wheel 24. The traction system of the utility model adopts a traction ratio of 1:1, has a simple structure, high transmission efficiency, and good control accuracy.
[0030] The guide wheel 24 is fixed on the frame 23 via a mounting frame 25. A limiting groove 26 is provided on the surface of the guide wheel 24 for the steel belt 22 to bypass. An anti-jump bracket 27 is provided above the guide wheel 24. A limiting plate 28 is provided on the anti-jump bracket 27. A ball 29 is provided at the bottom of the limiting plate 28, extending out of the anti-jump bracket 27 and corresponding to the limiting groove 26. The ball 29 is in rolling connection with the limiting plate 28. The steel belt 22 passes between the anti-jump bracket 27 and the guide wheel 24 on the limiting groove 26. The setting of the limiting groove 26 and the anti-jump bracket 27 can prevent the steel belt 22 from deviating or even jumping out of the guide wheel 24, thereby improving the traction stability and safety; and the rolling friction of the ball 29 can also reduce the wear of the steel belt 22 when it jumps out, thereby extending the service life of the steel belt 22.
[0031] The mounting frame 25 is provided with long grooves 251 on both sides, and the anti-jump bracket 27 is connected to the mounting frame 25 through the long grooves 251 via bolts 252. This design makes the height of the anti-jump bracket 27 adjustable, so that the restricted space of the anti-jump bracket 27 on the steel belt 22 can be flexibly adjusted according to actual conditions, which is more practical.
[0032] The anti-jump bracket 27 is provided with a mounting groove 271, the limiting plate 28 is movably installed in the mounting groove 271, and a compression spring 272 is provided between the top of the limiting plate 28 and the anti-jump bracket 27. Through the design of the compression spring 272, the ball 29 can be stably pressed on the surface of the steel belt 22, and the steel belt 22 needs to overcome the elastic force of the compression spring 272 when jumping, so that the steel belt 22 is not easy to jump, thereby improving the safety of the elevator.
