Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to an elevator guide rail and a car counterweight co - track elevator. Background Art

[0002] The traditional elevator structure is designed with the car and the counterweight arranged on different tracks, that is, two independent guide rails for the car and two independent guide rails for the counterweight. This type of structural design has two deficiencies. First, there is a large amount of space on both sides of the car guide rail that cannot be utilized. Second, the car is supported by only two guide rails, resulting in insufficient stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a guide rail that can guide both the car and the counterweight at the same time.

[0004] Another technical problem to be solved by the present invention is to provide an elevator that makes full use of the hoistway space and has more stable guidance.

[0005] To solve the above - mentioned technical problems, the present invention provides an elevator guide rail, including a first guiding portion and a second guiding portion; the first guiding portion and the second guiding portion are perpendicular to each other.

[0006] Preferably, the first guiding portion has three guiding surfaces.

[0007] Preferably, the second guiding portion has three guiding surfaces.

[0008] Preferably, the guiding surfaces are formed by machining.

[0009] The present invention also provides a car counterweight co - track elevator, including a car, a counterweight, a first elevator guide rail and a second elevator guide rail; the first elevator guide rail is the aforementioned elevator guide rail; the first guiding portion guides the car, and the second guiding portion guides the counterweight.

[0010] Preferably, the car counterweight co - track elevator includes two first elevator guide rails, and the first elevator guide rails are arranged on the same side of the car.

[0011] The present invention also provides a car counterweight co - track elevator, including a car, a counterweight and four first elevator guide rails; the first elevator guide rail is the elevator guide rail according to any one of claims 1 to 4; two of the first elevator guide rails are arranged on the same side of the car, and the other two first elevator guide rails are arranged on the other side of the car.

[0018] The following illustrates the implementation manners of the present invention through specific examples. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific implementation manners. The details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without departing from the overall design concept of the invention. It should be noted that, without conflict, the following examples and the features in the examples can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited only to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0019] Embodiment 1

[0020] As Figure 1 described, this embodiment provides an elevator guide rail including a first guiding portion 41 and a second guiding portion 42; the first guiding portion 42 and the second guiding portion 42 are perpendicular to each other. The elevator guide rail further includes a guide rail body 43. When the elevator guide rail is installed in the hoistway, it is fixed by pressing the guide rail body against the guide rail bracket. Usually, the first guiding portion has three guiding surfaces 411, 412, 413, and the second guiding portion also has three guiding surfaces 421, 422, 423. The guiding surfaces are formed into smooth surfaces by machining.

[0021] Embodiment 2,

[0022] As Figure 2As shown in the figure, this embodiment provides a car and counterweight co - track elevator, including a traction machine disposed at the top of the hoistway or in the machine room 7; a wire rope 3 bypasses the traction machine 1, one end is connected to the car top beam 8 at the top of the car 9, and the other end is connected to the counterweight through a counterweight pulley 2; two first elevator guide rails 4 are installed in the hoistway, and the first elevator guide rail 4 is the elevator guide rail described in Embodiment 1; a car guide shoe 5 is installed on the car, and a counterweight guide shoe 6 is installed on the counterweight. The car is guided by the guiding surface of the first guiding part through the car guide shoe 5, and the counterweight is guided by the guiding surface of the second guiding part through the counterweight guide shoe 6.

[0023] As Figure 3 shown, in this embodiment, the first elevator guide rails are arranged on the same side of the car. On the other side of the car, there are two second elevator guide rails. The second elevator guide rails can be T - shaped guide rails in the prior art or the same as the first elevator guide rails. The car and counterweight co - track structural design arranges the counterweight on the side of the car guide rails, making full use of the space on both sides of the car guide rails and eliminating the need to separately reserve space for counterweight arrangement. Compared with the traditional design of 2 guide rails for the car, the car in this embodiment adopts 3 or 4 guide rails, greatly improving the stability of the car.

[0024] As Figure 4 shown, in an alternative embodiment, the first elevator guide rails are arranged on the same side of the car. On the other side of the car, there is one second elevator guide rail. The three - rail type meets the certain stability requirements of the car while saving the cost of one guide rail.

[0025] As Figure 5 shown, in another alternative embodiment, the counterweight can be divided into two parts and arranged on both sides of the car respectively. Two of the first elevator guide rails are arranged on the same side of the car, and the other two first elevator guide rails are arranged on the other side of the car. The double - counterweight type can meet the design requirements of the energy consumption ratio system for large - tonnage elevators, and at the same time, divides the original large counterweight of the same mass into two small counterweights, reducing the risk of large impulse of the large counterweight.

[0026] The above has described the present invention in detail through specific embodiments and examples, but these do not constitute a limitation to the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many modifications and improvements, which should also be regarded as the protection scope of the present invention.
