A counterweight wheel installation structure for home elevators

Abstract

This utility model discloses a counterweight wheel installation structure for a home elevator, comprising two parallel counterweight frame beams. The key feature is that two upper beam plates perpendicular to the counterweight frame beams are provided at the ends of the beams, forming the installation space for the counterweight wheel. Each upper beam plate has several bolt holes. Shaft clamping plates are provided at both axial ends of the counterweight wheel and are fixed to a mounting plate. The mounting plate has tenons on both sides corresponding to the bolt holes. This design enables quick assembly and disassembly, as the mounting plate is plugged in and secured using a tenon-bolt structure, eliminating the need to disassemble all upper beam plates and other accessories. The integrated components, such as the shaft clamping plates, mounting plates, and sheave assembly, can be pre-assembled into modules, reducing the number of loose parts. The design, including the protective cover and symmetrical bolt holes, further reduces maintenance complexity.

Description

Technical Field

[0001] This utility model relates to the field of home elevator technology, specifically to an installation structure for counterweight wheels in home elevators, and more particularly to an installation structure for counterweight wheels that is easy to disassemble and maintain. Background Technology

[0002] Inorganic home elevators refer to an elevator structure in which the main unit, counterweight frame, and drive cabinet are directly arranged in the elevator shaft. The traction rope passes around the car's anti-coupling sheave, traction sheave, and counterweight sheave to transmit force and thus achieve the car's lifting and lowering. The counterweight frame is an essential component of traditional elevators. However, replacing, maintaining, or disassembling the counterweight sheaves in traditional counterweight frames requires disassembling the entire upper beam plate. Whether it's the counterweight sheave in a home elevator counterweight system as disclosed in patent publication number CN202279600U, or the counterweight sheave used in a side-mounted home elevator disclosed in patent publication number CN208883243U, the entire counterweight sheave assembly must be disassembled to complete the work. This structure is not only labor-intensive, cumbersome, and time-consuming, but also inconvenient for disassembly, assembly, and maintenance. Furthermore, because the shaft limiting mechanism and other components are independent parts, the number of parts is large, leading to significant negative effects on later maintenance. Additionally, traditional structures require repeated adjustments during reassembly, affecting efficiency. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned problems and provide a counterweight wheel installation structure for home elevators. It has the characteristics of fewer parts, ingenious structure, individual disassembly and maintenance of counterweight wheel components, simplified disassembly and assembly process through modular design, short time consumption, safety and reliability, improved maintenance efficiency, and low overall cost.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a counterweight wheel installation structure for a home elevator, comprising two parallel counterweight frame beams, characterized in that two upper beam plates perpendicular to the counterweight frame beams are provided at the ends of the counterweight frame beams, the counterweight frame beams and the two upper beam plates constitute the installation space of the counterweight wheel, and the two upper beam plates are provided with a plurality of bolt holes; axle clamping plates are provided at both axial ends of the counterweight wheel, and the axle clamping plates are fixed on the mounting plate; the mounting plate is provided with tenons on both sides corresponding to the bolt holes one by one.

[0005] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, the axle plate is provided with counterweight wheel axle mounting holes, which are either segmental or square holes, and the end of the counterweight wheel axle is a tangent of a round shaft or a square shaft structure that mates with the segmental hole.

[0007] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, the length of the upper beam plate is equal to the total width of the two parallel counterweight frame straight beams, the length of the mounting plate is less than or equal to the width of the upper beam plate, and the width of the mounting plate is equal to the distance between the two upper beam plates.

[0008] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, the bolt holes are arranged symmetrically along the length and width centerlines on the upper beam plate.

[0009] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, the tenon and the bolt hole are fitted with a clearance fit.

[0010] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, a counterweight wheel guard is provided between the two mounting plates, and the counterweight wheel guard is provided with a rope passage.

[0011] In the aforementioned counterweight wheel installation structure for a home elevator, preferably, the bolt hole is a rectangular hole.

[0012] This technical solution consists of a counterweight frame straight beam and two upper beam plates forming the counterweight wheel installation space. The axle clamp plate has either a circular or square hole that mates with the tangential or square end of the counterweight wheel axle to restrict axial displacement. The mounting plate and axle clamp plate are fixed with bolts, the spacing of which matches the axle length. The length of the upper beam plate is equal to the width of the straight beam, and the width of the mounting plate matches the spacing between the two upper beam plates, making it easy to match the mating parts one-to-one and reducing errors. Furthermore, the bolt holes are symmetrically distributed along the length and width centerlines, facilitating bidirectional installation. The tenon fits smoothly with the bolt holes, ensuring smooth assembly and disassembly. A counterweight wheel guard can be installed between the two mounting plates to protect the wheel groove and provide a rope passage. The bolt holes are rectangular in shape, providing installation tolerance.

[0013] Compared with the prior art, the advantages of this utility model are: it enables quick assembly and disassembly, and the mounting plate can be plugged in and fixed by means of tenon and bolt structure, without the need to disassemble all the upper beam plates and other accessories; the parts are integrated, and the shaft clamp plate, mounting plate and rope wheel assembly can be pre-assembled into modules, reducing the number of loose parts; the design of the protective cover and symmetrical bolt holes further reduces the complexity of maintenance.
