Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows: referring to fig. 1-2, a guidance system for an elevator includes:

the guide rail 1 is fixed on a well wall along the vertical direction, the guide rail 1 is provided with two guide surfaces 2 deviating from the well wall where the guide rail is located, a first included angle between the two guide surfaces 2 is alpha, and the angle is more than 0 degrees and less than 180 degrees;

with guide rail 1 sets up relatively and is fixed in guide shoe 3 on the car, guide shoe 3 including guide shoe support 4, set up in two gyro wheels 5 on the guide shoe support 4, two contained angle between the axis of gyro wheel 5 with first contained angle equals, each the outer fringe face 6 of gyro wheel 5 respectively with one the spigot surface 2 offsets, thereby makes guide shoe 3 follows the extending direction motion of guide rail 1.

When the guide system needs to be installed in a small shaft, because the space in the shaft is limited, the included angle between the axes of the two guide surfaces 2 and the two idler wheels 5 can be enlarged, so that the guide rails 1 and the guide shoes 3 are arranged in an extended mode towards two sides, the relative distance between the wall of the shaft and the wall of the lift car occupied by the guide rails is reduced, the space between the wall of the shaft and the wall of the lift car is fully utilized, and the use space of the lift car is ensured.

The first included angle alpha is 0 degrees < alpha <180 degrees, the adjustable range is large, the angle is flexible, and the application range is wide. Preferably, the first included angle α may be set to 90 °.

As shown in fig. 1 and 2, the width of the guide surface 2 in the radial direction is greater than the width of the roller 5 in the axial direction, so that the entire outer edge surface 6 of the roller 5 abuts against the guide surface 2, and the roller can stably roll in the extending direction of the guide surface 2.

Referring to fig. 1 and 2, the guide rail 1 may be formed in a V shape by re-processing a surface treatment using an existing angle iron. Simple structure and convenient manufacture. Compared with the existing T-shaped guide rail, the production cost can be reduced by about 30 percent, and the guide rail has more market competitiveness.

In the arrangement of the conventional guide system, the T-shaped guide rails are oppositely arranged on both sides of the hoistway wall, so that the length or width of the car is reduced, and therefore, the conventional T-shaped guide rails are not suitable for installation in a small hoistway. The guide rail 1 is arranged to be V-shaped, and can be fixed on the oblique opposite angle of the well in different fixing modes such as welding, nuts and the like, so that corners in the well can be flexibly utilized. According to in the rectangle, the diagonal is the longest, set up along diagonal relatively, can reduce its occupation on length or width, guarantee the space in the car in the little well.

Referring to fig. 4 and 5, the guide shoe support 4 includes a base 7 fixedly connected to the car, and a roller bracket 8 welded to the base 7 for fixing the roller 5.

The roller 5 is rotatably connected to one end of a roller shaft, and the other end of the roller shaft is fixed on the roller bracket 8 through a nut assembly 9.

As shown in fig. 4 and 5, the base 7 is provided with a plurality of waist-shaped through holes 11 for connecting with the car. The waist-shaped through hole 11 is arranged, so that the relative position of the guide shoe 3 and the car can be adjusted more conveniently when the guide shoe 3 is fixed, and the outer edge surface 6 of the roller 5 is completely abutted against the guide surface 2.

Example two: referring to fig. 3, a guide system for an elevator, in the present embodiment, has a structure substantially similar to that of the embodiment, except that the guide rail 1 includes a rail housing 12 for fixedly coupling with a hoistway wall, and a guide body 13 integrally coupled to the rail housing 12, and the guide body 13 has an isosceles trapezoid shape. The two sides of the guide body 13 are provided with guide surfaces 2, and a first included angle between the two guide surfaces 2 is alpha, wherein alpha is more than 0 degree and less than 180 degrees.

In a preferred embodiment, a shock absorbing pad 10 is further sleeved on the roller shaft, and the shock absorbing pad 10 is located between the roller 5 and the roller bracket 8. The elevator car has the advantages that the effects of shock absorption, noise reduction and the like can be achieved, the car runs more stably, and the elevator is more comfortable to take.

The principle and the implementation mode of the invention are explained by applying specific embodiments in the invention, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
