Description

Technical Field

[0001] This utility model relates to the field of elevator host installation technology, and in particular to a platform elevator host base. Background Technology

[0002] The traction machine, a core component of an elevator, is commonly referred to as a steel belt machine or wire rope machine. The performance and design of its mounting base—the machine base—are crucial, directly impacting the elevator's operational stability, lifespan, and installation and maintenance efficiency. Traditional elevator machine bases have gradually revealed some common problems that urgently need to be addressed through long-term use. Traditional machine base structures are often redundant, with insufficiently compact component layouts. This necessitates reserving a large installation area in the traction machine room (i.e., the top floor space), increasing construction costs or hindering application in space-constrained environments. The positioning and fixing of critical components such as the machine base, guide rails, and speed governor often require extensive on-site measurement, adjustment, and welding work. In particular, the guide rail installation requires high precision, making the process cumbersome, inefficient, and prolonging the project cycle. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a platform elevator main unit base.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A platform elevator main unit base includes a main unit base plate, a guide rail bracket, main rails, auxiliary rails, and reinforcing ribs. A reinforcing rib is welded to each side of the top surface of the main unit base plate. The guide rail bracket is bolted to both ends of the main unit base plate. Two sets of guide rail fixing holes are provided on the guide rail bracket. The main rail and auxiliary rail are locked to the guide rail bracket by bolts passing through the two sets of guide rail fixing holes. The steel belt main unit is bolted to the main unit base plate. Two parallel, waist-shaped steel belt lower rope holes are provided on the main unit base plate corresponding to the output shaft of the steel belt main unit. Two rope head mounting holes are provided on each side of the steel belt lower rope holes. A speed limiter mounting hole is provided on the main unit base plate corresponding to the front of the steel belt main unit output shaft. Speed ​​limiter lower rope holes are provided on the main unit base plate before and after the speed limiter mounting hole.

[0005] The main unit base plate has oblong holes on the top surface of both ends, and the main unit base plate locks the guide rail bracket by threading bolts through the oblong holes.

[0006] The guide rail bracket is an L-shaped plate, with its short side abutting against the bottom surface of the main unit base plate and the main unit base plate and guide rail bracket being locked together with bolts.

[0007] The guide rail bracket has two waist-shaped spare guide rail fixing holes on each side of the guide rail fixing mounting hole.

[0008] The main rail and the auxiliary rail each have four mounting holes at the top and bottom, and the relative positions of the four mounting holes correspond to the positions of the guide rail fixing mounting holes on the guide rail bracket.

[0009] The inner side of the guide rail bracket is connected to a pressure plate via bolts through the guide rail fixing spare holes.

[0010] The pressure guide plate includes a U-shaped pressure guide plate and a pressure block with a guide groove on one side. The pressure block is pressed against the two sides of the main rail through the guide groove, and the U-shaped pressure guide plate is pressed against the two sides of the auxiliary rail through one side.

[0011] The contact surface between the steel strip main unit and the main unit base plate is provided with a main unit pad.

[0012] The beneficial effects of this utility model are as follows: By highly integrating and compactly arranging the main unit base plate, guide rail bracket, reinforcing ribs, and speed limiter mounting holes, this utility model not only reduces the number of components, effectively disperses and transfers loads, avoids stress concentration, and enhances the rigidity and stability of the overall structure, but also reduces the connection space and gap between the rope head plate and the main unit base in traditional designs, thereby effectively reducing the space occupied on the top layer. The pre-drilled spare mounting holes on the main unit base plate not only improve installation accuracy but also enhance the applicability of the main unit base. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: A platform elevator main unit includes a main unit base plate 2, a guide rail bracket 4, a main rail 7, a secondary rail, and reinforcing ribs 3. A reinforcing rib 3 is welded to each side of the top surface of the main unit base plate 2, effectively enhancing its bending and torsional strength. The guide rail bracket 4 is bolted to both ends of the main unit base plate 2. Two sets of guide rail fixing holes 400 are provided on the guide rail bracket 4. The main rail 7 and secondary rail 6 are locked to the guide rail bracket 4 by bolts passing through the two sets of guide rail fixing holes 400. The steel belt main unit 1 is bolted to the main unit base plate 2. Two parallel, waist-shaped steel belt lower rope holes 501 are provided on the main unit base plate 2 corresponding to the output shaft position of the steel belt main unit 1. Two rope head mounting holes 500 are provided on each side of the steel belt lower rope holes 501. A speed limiter mounting hole 601 is provided on the main unit base plate 2 corresponding to the front position of the output shaft of the steel belt main unit 1. Speed ​​limiter lower rope holes 600 are provided on the main unit base plate 2 on the front and rear sides of the speed limiter mounting holes 601.

[0015] The main unit base plate 2 has oblong holes on the top surface of both ends, and the main unit base plate 2 locks the guide rail bracket 4 by threading bolts through the oblong holes.

[0016] The guide rail bracket 4 is an L-shaped plate. The short side of the guide rail bracket 4 abuts against the bottom surface of the main unit base plate 2 and is locked with bolts to the main unit base plate 2 and the guide rail bracket 4.

[0017] The guide rail bracket 4 has two waist-shaped spare guide rail fixing holes 401 on each side of the guide rail fixing mounting hole 400.

[0018] The main rail 7 and the auxiliary rail 6 each have four mounting holes 700 at the top and bottom, and the relative positions of the four mounting holes 700 correspond to the positions of the guide rail fixing mounting holes 400 on the guide rail bracket 4.

[0019] The inner side of the guide rail bracket 4 is bolted with a pressure plate 701 through the guide rail fixing spare hole 401.

[0020] The pressure plate 701 includes a U-shaped pressure plate 7011 and a pressure block 7012 with a guide groove on one side. The pressure block 7012 is pressed against the two sides of the main rail 7 through the guide groove, and the U-shaped pressure plate 7011 is pressed against the two sides of the auxiliary rail 6 through one side.

[0021] The contact surface between the steel strip main unit 1 and the main unit base plate 2 is provided with a main unit pad 5.

[0022] The main unit base plate 2 is made of high-strength steel with a thickness of 12mm, effectively withstanding various loads generated during elevator operation. The main unit base plate 2 is bolted to the guide rail bracket 4. The use of pre-drilled holes and standardized bolt connections significantly simplifies the installation process. Installers only need to insert the bolts into the pre-drilled holes and tighten them according to the design requirements, eliminating the need for complex welding or adjustments, thus reducing installation time and labor costs. The bolt connection allows for fine-tuning and correction within a certain range, ensuring the main unit base is accurately installed in the predetermined position. This flexibility makes the installation process more efficient, especially suitable for complex site conditions or space-constrained environments. The bolt connection operation is simple and can be completed without specialized technicians, reducing the technical requirements for installers. Simultaneously, bolt connection tools, such as wrenches, are easy to carry and use, further improving installation convenience. The fully bolted installation method allows for easy disassembly and reinstallation of the main unit base when maintenance or repair is required. Simply loosen the bolts to remove the main unit base from the bracket for necessary maintenance or replacement without damaging other structures.
