[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] In order to solve the problems of heavy weight, poor running stability and mechanical strength, and complicated connection of the guide rail in the prior art, please refer to Figure 1-5 , this embodiment provides the following technical solutions:
[0027] A hollow guide rail for counterweight and balance of an elevator comprises a top plate 1 and side plates 2. The side plates 2 are symmetrically arranged on both sides of the top plate 1. The plane where the side plates 2 are located is perpendicular to the plane where the top plate 1 is located and connected to the top plate 1. An inclined plate 3 is arranged at the bottom of the side plate 2. The two inclined plates 3 are distributed in a mirror-symmetrical manner. The angle between the inclined plates 3 ranges from 15° to 120°. The appropriate angle can reduce the impact force, prevent dislocation, and enhance the overall structural strength of the guide rail.
[0028] A connecting panel 4 is horizontally connected to the outer side of the bottom of the inclined plate 3. The connecting panel 4 is provided with bolt holes for installation. The outer edge of the connecting panel 4 is provided with an upwardly curved surface 5. The height of the curved surface 5 is in the range of 5mm to 35mm, which increases the strength of the guide rail edge and improves the durability of the connection part.
[0029] The top plate 1, the side plate 2, the inclined plate 3, the connecting panel 4 and the curved surface 5 are manufactured by cold rolling forming from galvanized steel plates with a thickness of 1.5 mm to 4 mm. This thickness range is selected because it can ensure that the guide rail has sufficient strength and rigidity to support the weight of the elevator counterweight or balance weight, while ensuring the economy of the material and the convenience of processing.
[0030] The top surface of the top plate 1 is a plane or an arc surface. Different top surface shapes are adapted to the requirements of different types of elevator systems. The plane type is suitable for most traditional applications to provide a flat contact surface, while the arc type can improve stability or reduce friction in certain situations. The width of the top plate 1 ranges from 5mm to 18mm, which ensures that the guide rail has enough width to maintain structural stability without taking up too much space.
[0031] A connecting guide plate for hollow guide rails for counterweight and balance weight of elevators, comprising a dome edge 6, with side edges 7 provided on both sides of the bottom of the dome edge 6, the side edges 7 being vertically arranged, the bottom of the side edges 7 being connected to a bevel edge 8, the angle range of adjacent bevel edges 8 being 15° to 120°, ensuring that the bevel edge 8 matches the bevel plate 3 of the guide rail and avoiding installation problems caused by inconsistent angles; a horizontally arranged connecting edge 9 is connected to the outer side of the bottom of the bevel edge 8, the connecting edge 9 is provided with bolt holes for installation, an upwardly bent edge 10 is provided at the outer edge of the connecting edge 9, the height range of the bend 10 being 5mm to 40mm, for strengthening the connection strength between the guide rail and the outer end of the connecting guide plate and ensuring a smooth transition, the height of the bend 10 being higher than the height of the curved surface 5, ensuring that the bend 10 and the curved surface 5 can be flush after installation.
[0032] The thickness of the dome edge 6, the side edge 7, the bevel edge 8, the connecting edge 9 and the curved edge 10 ranges from 2 mm to 8 mm. The moderate thickness ensures that the connecting guide plate has the necessary strength, while facilitating transportation and installation and reducing the difficulty of construction.
[0033] A method for installing a hollow guide rail and a guide plate for counterweight and balancing weight of an elevator is based on a hollow guide rail for counterweight and balancing weight of an elevator and a guide plate for connecting the hollow guide rail for counterweight and balancing weight of an elevator, and comprises the following steps:
[0034] Step 1: Place the two hollow guide rail sections to be connected at the predetermined position, and ensure that the joint surface between the guide rails is clean and free of foreign matter;
[0035] Step 2: Place the connecting guide plate below the joint of the two hollow guide rails, so that the dome edge 6 and the side edge 7 penetrate into the top plate 1 and the side plate 2, until the connecting edge 9 and the connecting panel 4 are in contact, at which time the curved edge 10 is in contact with the curved surface 5, and the side edge 7 is in contact with the side plate 2;
[0036] Step 3: Use bolts 11 to pass through the corresponding bolt holes of the connecting edge 9 and the connecting panel 4 and install them to achieve the installation of the connecting guide plate and the hollow guide rail.
[0037] Working principle: When the elevator car moves up and down, the counterweight or balance weight slides along the hollow guide rail. The top plate 1 of the guide rail (whether it is flat or arc-shaped) provides a smooth movement path for the counterweight or balance weight, ensuring its precise displacement in the vertical direction. The connecting plate achieves seamless connection between the guide rail sections by precisely matching the inclined plate 3 and curved surface 5 of the guide rail through the inclined edge 8 and curved edge 10. This connection method not only maintains the continuity of the guide rail system, but also strengthens the mechanical strength between the sections of the guide rail to prevent dislocation or loosening.
[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0039] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
