Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail technology, specifically a hollow guide rail for elevators. Background Technology

[0002] In elevator operating systems, hollow guide rails are the core guiding components of the counterweight device, and their performance directly affects the stability and safety of elevator operation. The design of HT60-K guide rails needs to be selected according to the speed and load capacity of the elevator.

[0003] Existing guide rails are mostly integral heavy-duty structures with low modularity and large weight. During installation in elevator shafts, they require the use of large hoisting equipment, and subsequent maintenance and replacement require the disassembly of a large number of parts, which is cumbersome, time-consuming and labor-intensive, increasing maintenance costs. At the same time, most hollow guide rails are not optimized for corrosion prevention and vibration reduction, have weak surface rust prevention capabilities, and are prone to corrosion when exposed to the humid and dusty environment of the shaft for a long time. They also lack effective internal vibration damping filling, resulting in significant noise and vibration during operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hollow guide rail for elevators. It solves the problems of existing guide rails being mostly integral heavy-duty structures with low modularity, large weight, requiring large hoisting equipment during elevator shaft installation, and necessitating the disassembly of numerous components for subsequent maintenance and replacement, resulting in cumbersome, time-consuming, and labor-intensive operations and increased maintenance costs. In addition, most hollow guide rails are not optimized for corrosion prevention and vibration reduction, have weak surface rust resistance, are prone to corrosion in the humid and dusty environment of the shaft, and lack effective internal vibration damping filling, resulting in significant noise and vibration during operation.

[0005] This utility model provides the following technical solution: a hollow guide rail for elevators, including a hollow guide rail, a first connecting plate, a second connecting plate, and a third connecting plate. The surfaces of the hollow guide rail, the first connecting plate, the second connecting plate, and the third connecting plate are all provided with a plurality of corresponding threaded holes, and bolts are installed in the threads inside the corresponding threaded holes.

[0006] Both ends of the hollow guide rail are fixedly connected to short plates on their inner walls. The surfaces of the two short plates are fixedly connected to positioning rods. The surfaces of the first connecting plate and the second connecting plate are fixedly connected to mounting plates. The surfaces of the two mounting plates are provided with positioning holes that match the positioning rods.

[0007] Preferred technical solution 1: The hollow guide rail body is a hollow structure integrally formed from galvanized sheet.

[0008] Preferred technical solution 2: A positioning block is fixedly connected to one end of the first connecting plate, and a positioning groove matching the positioning block is opened on the surface of the second connecting plate.

[0009] Preferred technical solution three: Each bolt surface is fitted with an anti-slip pad.

[0010] Preferred technical solution four: Both ends of the hollow guide rail are provided with end caps, and the end caps are made of polystyrene.

[0011] Preferred technical solution five: The internal cavity of the hollow guide rail is filled with polystyrene particles.

[0012] Compared with the prior art, this utility model provides a hollow guide rail for elevators, which has the following advantages: First, adjacent hollow guide rails are connected and assembled. The operator first inserts the first connecting plate into the positioning rod on the inner short plate of one section of the hollow guide rail, and then inserts the second connecting plate into the positioning rod on the inner short plate of another section of the hollow guide rail to achieve initial positioning, keeping the first and second connecting plates stable and preventing shaking. Then, the two sections of hollow guide rails are brought closer together, and the positioning block fixedly connected to one end of the first connecting plate is embedded in the positioning groove opened on the surface of the second connecting plate to ensure that the positions of the first and second connecting plates are accurately aligned. Next, the third connecting plate is attached to the other side of the two sections of hollow guide rails, so that the hollow guide rails and the first connecting plate are aligned. Multiple threaded holes on the surfaces of the first, second, and third connecting plates are fully aligned. Bolts fitted with anti-slip pads are then screwed into the corresponding threaded holes and tightened, completing the secure connection of adjacent hollow guide rails. After the hollow guide rails are assembled, polystyrene particles are filled inside. End caps are then inserted at both ends of the hollow guide rails to seal the internal cavity. During elevator operation, the hollow guide rails can stably perform their counterweight guiding function, and the polystyrene particles provide vibration and noise reduction. This invention allows for rapid assembly of hollow guide rails. The hollow guide rails are integrally formed from galvanized steel sheets, and the internal polystyrene particles reduce vibration and noise. Overall installation is convenient, maintenance is easy, and the stability and service life of the elevator's counterweight guiding function are improved. Attached Figure Description
