AI Technical Summary
The hollow guide rail has the risk of being squeezed and deformed when the elevator safety clamp is operated, which limits its use scenarios and can only be used when there is no safety clamp on the counterweight side.
A semi-solid hollow guide rail is designed to ensure that the guide rail has sufficient stiffness when the safety clamp is operated by fixing the limiting parts at the tail of the guide rail and adding fillers such as cast iron and mineral powder materials into the internal cavity of the guide rail, or using pressure adjustable high-pressure air or magnetorheological fluid as the filler.
The safety pliers brake function used by hollow guide rails on the side of the car is realized, reducing the impact of elevator operation on the comfort of building residents, and maintaining the temperature of the guide rails through the heat storage effect of the material.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevators, and particularly to a semi-solidified hollow guide rail. Background Art
[0002] Hollow guide rails are deeply loved by the elevator industry because of their advantages of light weight and low cost when the cross-sectional strength is sufficient. However, when the elevator safety gear operates, there is a risk of extrusion deformation of the hollow guide rail, which greatly limits the usage scenarios of the hollow guide rail, making the hollow guide rail only applicable when there is no safety gear on the counterweight side. Summary of the Invention
[0003] The technical problem to be solved by the present invention is how to provide a hollow guide rail capable of safety gear braking.
[0004] To solve the above technical problem, a semi-solidified hollow guide rail provided by the present invention includes a hollow guide rail, a limiting member, and a filler; the limiting member is fixed at the tail of the hollow guide rail, and the filler is fixed in the internal cavity of the hollow guide rail.
[0005] Preferably, the limiting member is a steel plate and is fixed to the hollow guide rail by welding.
[0006] Preferably, the filler is made of cast iron material and mineral powder material.
[0007] The present invention also provides a semi-solidified hollow guide rail, including a hollow guide rail, a limiting member, and a filler; the limiting member is fixed on the periphery of the hollow guide rail to seal the internal cavity of the hollow guide rail; the filler is high-pressure air with adjustable pressure.
[0008] The present invention also provides a semi-solidified hollow guide rail, including a hollow guide rail, a limiting member, and a filler; the limiting member is fixed on the periphery of the hollow guide rail to seal the internal cavity of the hollow guide rail; the filler is magnetorheological fluid.
[0009] Compared with the prior art, the present invention has the following technical effects:
[0010] 1. The added filler has a certain stiffness, enabling the hollow guide rail to perform safety gear braking and thus be used on the car side.
[0011] 2. If the added filler has a shock-absorbing effect, it can reduce the impact of elevator operation on the comfort of building residents.
[0012] 3. If the added material has a heat storage effect, it can store the heat generated by the friction between the guide rail and the guide shoe and maintain the temperature of the guide rail. Brief Description of the Drawings
[0013] The following further elaborates the present invention in detail in conjunction with the drawings and specific embodiments:
[0014] Figure 1 Schematic diagram of the semi-solidified hollow guide rail structure of Example 1. Specific implementation manners
[0015] The following describes the implementation manners of the present invention through specific embodiments. 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 embodiments and the features in the embodiments 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 described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention complete and thorough, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.
[0016] Example 1
[0017] As Figure 1 shown, this embodiment provides a semi-solidified hollow guide rail, including a hollow guide rail 1, a limiting member 3, and a filler 2.
[0018] A steel plate is welded to the tail of the hollow guide rail 1 as the limiting member 3, and the filler 2 is added to the internal cavity of the hollow guide rail 1. The filler 2 can be cast iron material and mineral powder material. The prices of these two materials are relatively low compared to steel materials, and can meet the stiffness requirements when the safety clamp operates, enabling the hollow guide rail to be used when there is a safety clamp on the car side.
[0019] Example 2
[0020] This embodiment provides a semi-solidified hollow guide rail, including a hollow guide rail, a limiting member, and a filler.
[0021] The limiting member is fixed on the periphery of the hollow guide rail to seal the internal cavity of the hollow guide rail; the filler is high-pressure air with adjustable pressure. By adjusting the pressure of the high-pressure air, the stiffness of the hollow guide rail can be changed to meet the stiffness requirements when the safety clamp operates, enabling the hollow guide rail to be used when there is a safety clamp on the car side.
[0022] Example 3
[0023] This embodiment provides a semi-solidified hollow guide rail, which includes a hollow guide rail, a limiting member, and a filler. The limiting member is fixed on the periphery of the hollow guide rail to seal the internal cavity of the hollow guide rail; the filler is magnetorheological fluid. A device that generates a magnetic field can be added on both sides of the safety clamp, so that the stiffness of the filler 2, i.e., the magnetorheological fluid, inside the part of the hollow guide rail passed by the safety clamp increases, meeting the stiffness requirements when the safety clamp operates, and enabling the hollow guide rail to be used in the case where there is a safety clamp on the car side.
[0024] The above has described the present invention in detail through specific implementation manners and embodiments, but these do not constitute limitations on the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many deformations and improvements, which should also be regarded as the protection scope of the present invention.
