Description

Technical Field

[0001] The present application relates to an elevator guide rail and guide shoe system, belonging to the technical field of elevators. Background Art

[0002] An elevator guide rail system generally consists of a guide rail and corresponding guide shoes. The cross-sectional shape of the guide rail generally has forms such as T-shaped and L-shaped. While the guide rail plays a guiding role, it bears the impact force of the car during elevator braking, the impact force during the emergency braking of the safety clamp, etc. The magnitudes of these forces are related to the load mass and speed of the elevator. Therefore, the guide rail should be selected according to the elevator speed and load mass. For example, the utility model patent with the publication number CN104261231A discloses an elevator roller guide shoe, specifically: the elevator roller guide shoe is installed on the elevator guide rail, a spring is installed between the shoe seat and the L-shaped bracket, and a floating fit is adopted, solving the problem that it is difficult to control the installation accuracy of the traditional guide shoe. Moreover, the spring plays an adaptive function and can be pressed against the guide rail during the operation of the elevator to ensure the smooth operation of the elevator. However, the elevator guide rail in the above patent uses a guide rail with a T-shaped cross-section. This guide rail has a single guiding platform. During the long-term operation of the elevator or when the safety clamp tightly clamps the guide rail body during an emergency brake of the elevator, it may generate a strong impact force on the guide rail, increasing the braking distance and the heat generation at the same time.

Detailed Embodiments

[0021] The following describes the present application in detail in conjunction with embodiments, but the present application is not limited to these embodiments.

[0022] See Figures 1-3 , an elevator guide rail and guide shoe system, characterized by comprising:

[0023] A guide rail 1, the guide rail 1 includes a guide rail plate 2, two parallel guide platforms 3 are arranged on the guide rail plate 2, a guide groove 4 is arranged on the outer side of the guide platform 3 along the length direction of the guide platform 3, and a cooling cavity 5 is arranged inside the guide platform 3 along the length direction of the guide platform 3;

[0024] Specifically, the cross-section of the guide rail is integrally in a "Π" shape, the guide rail has two guide platforms, the double guide platforms can reduce the emergency braking distance of the car, a cooling cavity is arranged inside each guide platform, reducing the heat generated during long-term operation or emergency braking, and can effectively reduce the temperature of the guide rail during high-speed and long-term operation of the elevator, improving the operation safety and service life.

[0025] A guide shoe 6, the guide shoe 6 includes a shoe seat, a pair of positive guide wheels 7 and a pair of side guide wheels 8 are installed on the shoe seat, the pair of side guide wheels 8 are respectively located on both sides of the two parallel guide platforms 3 and roll on the corresponding guide grooves 4, and the positive guide wheels 7 are located on the surface of the guide platform 3 and roll on the upper surface of the corresponding guide platform 3.

[0026] Specifically, the side guide wheels cooperate with the guide grooves. When the elevator is running at high speed, the trapezoidal guide grooves can prevent the lateral swing of the car. The positive guide wheels are adapted to the front surface of the guide platform. A plurality of screw holes are arranged on the shoe seat for connecting the car. The guide shoe is provided with side guide wheels and positive guide wheels. The positive guide wheels and the side guide wheels move in a rolling manner with the guide rail (guide platform) to reduce friction. By arranging two guide platforms on the guide rail, when the safety clamp clamps the guide rail during emergency braking of the elevator, it can generate friction with the safety clamp at the same time, generating a large longitudinal impact force, and dispersing the impact force to the two guide platforms. The two guide platforms bear the force together, which can reduce the braking distance and reduce the heat generation.

[0027] The shoe seat includes an upper shoe plate 9 and a lower shoe plate 10, and the upper shoe plate 9 and the lower shoe plate 10 are connected by a shoe plate bracket;

[0031] A plurality of heat dissipation fins 13 are arranged in the cooling chamber 5;

[0032] The heat dissipation fins 13 are staggeredly arranged on opposite side walls of the cooling chamber 5 .

[0033] Specifically, a plurality of heat dissipation fins are arranged in the cooling chamber. When the elevator runs for a long time or brakes urgently, the heat dissipation fins can dissipate heat for the guide rail in time by increasing the contact area between the guide rail and the air.

[0034] The groove section of the guide groove 4 is trapezoidal.

[0035] Specifically, a trapezoidal guide groove is provided on the side of the guide platform, which can improve the stability of the car during operation.
