Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a guide rail heating device. Background Art

[0002] In the elevator system, when the safety clamp of a high-speed elevator is braking, if the guide rail temperature is too low, the friction coefficient of the safety clamp will be unstable when braking, and in severe cases, the brake will fail, which seriously affects the safety of the elevator. Currently, there is no relevant patent to solve this problem. If there is a method to ensure that the temperature of the contact part of the guide rail of the safety clamp is appropriate when braking, it will be of great significance to strengthen the safety clamp of high-speed elevators. Summary of the invention

[0003] The technical problem to be solved by the present invention is to ensure that the temperature of the contact part of the guide rail is appropriate when the safety clamp is braking.

[0004] To solve the above technical problems, the present invention provides a guide rail device, including a guide rail preheating device, which is arranged between the guide shoe extension seat and the guide shoe and adjacent to the guide rail, and can move with the elevator to heat the low-temperature section of the guide rail.

[0005] Specifically, the guide rail preheating device comprises a guide rail preheating device structural member for connection and a heating device for heating.

[0006] Specifically, the guide rail preheating device structure consists of an upper connecting piece, a middle connecting piece and a lower connecting piece. The upper connecting piece is connected to the guide shoe extension seat; the lower connecting piece is connected to the guide shoe; and the middle connecting piece is used to install and support the heating device.

[0007] Specifically, the heating device includes an electrical device and a heating element. The electrical device is installed on the middle connecting piece, and the heating elements are arranged on both sides of the guide rail. When the high-speed elevator speed limiter is electrically triggered, the elevator control system starts the electrical device to supply power to the heating element.

[0008] Specifically, the rail temperature is below 2 degrees Celsius.

[0009] Specifically, the heating element is a coil, which can generate eddy current inside the guide rail, thereby heating the guide rail.

[0010] Specifically, the heating element is a laser emitter, which can emit a shaped multi-mode laser rectangular spot to the surface of the guide rail to heat the guide rail.

[0011] Specifically, the heating device also includes a temperature measuring element for adjusting the output power of the heating element, thereby controlling and adjusting the heating temperature of the guide rail.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] The guide rail device of the present invention moves along the guide rail following the elevator car and can heat the guide rail in the braking range to a temperature suitable for the safety clamp braking when the high-speed elevator safety clamp is braking.

[0014] The guide rail preheating device 4 is arranged between the guide shoe extension seat 3 and the guide shoe 5 and moves with the elevator. The guide rail preheating device 4 comprises a guide rail preheating device structural member 41 for connection and a heating device 42 for heating.

[0015] The device of the present invention can locally heat the guide rail instantaneously without the need to normally heat the entire guide rail, thus saving costs and being environmentally friendly. If the guide rail is accidentally frozen, the device can be activated to perform de-icing. In addition, the guide rail preheating device can be integrated with other functions such as acceleration detection, and has extremely high scalability. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] DETAILED DESCRIPTION

[0023] The following describes the implementation methods of the present invention through specific specific embodiments, and those skilled in the art can fully understand other advantages and technical effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through different specific implementation methods, and the details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without deviating from the overall design concept of the invention. It should be noted that the following embodiments and the features in the embodiments can be combined with each other in the absence of conflict. The following exemplary embodiments of the present invention can be implemented in a variety of different forms and should not be interpreted as being limited to the specific embodiments described 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.

[0024] Example 1

[0025] Figure 1 The elevator car system 6 is connected to the safety clamp and its frame 1, the safety clamp and its frame 1 are connected to the guide shoe extension seat 3, the guide shoe extension seat 3 is connected to the guide shoe 5, and the whole system moves up and down along the guide rail 2.

[0026] Figure 2 The guide rail preheating device 4 is arranged between the guide shoe extension seat 3 and the guide shoe 5, and moves up and down along the guide rail 2 along with the entire system.

[0027] Figure 3 The figure is a structural diagram of the guide rail preheating device. The guide rail preheating device structural member 41 is connected to the guide shoe extension seat 3 through the upper connecting member 411 by fasteners; and is connected to the guide shoe 5 through the lower connecting member 413 by fasteners. The electrical device 422 of the heating device 42 is installed on the middle connecting member 412, and the heating element 421 is arranged on both sides of the guide rail 2. The heating element is forked at the end to be fixed on both sides of the guide rail. When the high-speed elevator speed limiter is electrically triggered, the elevator control system starts the electrical device 422 to supply power to the heating element 421. Specifically, the trigger condition is when the temperature is lower than 2 degrees. The heating element 421 can be a coil, which can generate eddy currents inside the guide rail 2, thereby heating the guide rail 2 and playing the role of preheating the guide rail; the heating element 421 can also be a laser emitter, which can emit a shaped multi-mode laser rectangular spot to the surface of the guide rail 2 to uniformly heat the guide rail 2. When the speed limiter of a high-speed elevator is mechanically triggered, the elevator control system keeps the electrical device 422 started to supply power to the heating element 421. Due to the existence of the guide shoe extension seat 3, there is a distance difference between the safety clamp and its frame 1 and the guide rail preheating device 4, and the induction heating or laser heating takes a short time, so the heating device 42 can achieve the goal of preheating the guide rail 2. After the elevator stops, the elevator control system disconnects the electrical device 422 and no longer supplies power to the heating element 421. At the same time, the heating device 42 is also equipped with a temperature measuring element 423, which is used to adjust the output power of the heating element 421, and thus its heating effect on the guide rail 2.

[0028] The present invention has been described in detail above through specific implementation modes and embodiments, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
