Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a compact oil-free guide shoe for small shaft elevators such as villa elevators. Background Technology

[0002] Guide shoes are crucial connecting components between elevator guide rails and the car. Installed on the upper beam and bottom of the car frame, they guide the car and counterweight along the guide rails. Traditional guide shoes typically require oil cups for regular lubrication to reduce friction between the shoe liner and the guide rails. However, for home elevators such as those in villas, the shaft space is usually quite compact. Installing oil cups not only takes up space but also presents drawbacks such as oil leaks polluting the shaft environment and the need for regular lubrication maintenance.

[0003] Furthermore, existing guide shoe structures often suffer from problems such as inconvenient assembly and disassembly, insufficient structural strength, or poor cushioning effect, making it difficult to meet the comprehensive requirements of villa stairs for space saving, maintenance-free operation, and stable operation. Therefore, there is an urgent need for a guide shoe solution that is compact, requires no additional lubrication, and operates stably and reliably. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a compact, maintenance-free, stable-operating, and easy-to-disassemble oil-free guide shoe for villa stairwells. The specific technical solution is as follows: A compact, oil-free guide shoe for villa stairwells, comprising: A fixed mounting bracket has an assembly slot in the center and mounting parts symmetrically arranged on both sides of the assembly slot; A contact boot liner, the contact boot liner being disposed within the assembly groove, having a U-shaped cross-section to form a boot liner groove; Two pads are respectively placed between the two sides of the contact boot liner and the inner sidewall of the assembly groove.

[0012] Preferably, the material of the contact boot liner contains graphene.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, the integrated design of the fixed base plate, L-shaped fixed side plate, and fixed reinforcing plate, along with the interlocking structure of the external protrusion and the mounting opening between the side plate and the reinforcing plate, greatly enhances the rigidity and strength of the guide shoe body while ensuring a compact structure. It is particularly suitable for villa stairwells with limited space.

[0014] Secondly, the contact boot liner contains graphene material, which can generate lubricating substances on its own during friction, completely eliminating the need for an external oil cup, fundamentally avoiding the risk of oil leakage, achieving lifetime maintenance-free operation, saving maintenance costs, and being more environmentally friendly.

[0015] Thirdly, the nitrile rubber pads installed on both sides of the boot liner can not only fill the gaps to ensure the boot liner is installed firmly, but also effectively buffer the vibration and impact during elevator operation, thus improving ride comfort.

[0016] Fourthly, the disassembly notch on the fixed side plate provides operating space for tools, so that the guide shoe body does not need to be completely disassembled when replacing the shoe liner or pad, which greatly simplifies the maintenance process and saves time and manpower.

Detailed Implementation

[0019] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0021] like Figures 1 to 3 As shown, a compact villa stairwell oil-free guide shoe mainly consists of a fixed mounting bracket 1, two pads 2, and a contact shoe liner 3.

[0022] The fixed mounting bracket 1, serving as the main load-bearing structure, is integrally bent or welded from a metal plate. It includes a rectangular fixed base plate 12. On the upper surface of the fixed base plate 12, two L-shaped fixed side plates 13 are symmetrically arranged, with a certain distance between them, forming an assembly groove 11 for accommodating the contact shoe liner 3 and the pad 2. To greatly enhance structural strength, a fixed reinforcing plate 14 is vertically arranged at each of the two outer ends of each fixed side plate 13. The lower edge of the fixed reinforcing plate 14 is welded to the side of the fixed base plate 12. Furthermore, external protrusions 17 are stamped onto the outer surface of the fixed side plates 13, and corresponding mounting openings 18 with matching shapes are opened on the fixed reinforcing plates 14. During assembly, the external protrusions 17 are inserted into the mounting openings 18, achieving precise positioning and reinforced connection between the side plates and the reinforcing plates.

[0023] In the above implementation, the fixed base plate 12 and the fixed side plate 13 are connected by a spot welding process; the fixed reinforcing plate 14 is connected to the fixed base plate 12 and the fixed side plate 13 by a spot welding process.

[0024] The inner edge of the fixed reinforcing plate 14 extends toward the center of the assembly groove 11, partially blocking the opening end of the assembly groove 11, which can effectively prevent the internal pad 2 and contact shoe liner 3 from coming out during elevator operation vibration.

[0025] The contact shoe liner 3 is made of a wear-resistant composite material mixed with graphene, and its cross-section is U-shaped. The resulting shoe liner groove 31 is used to engage the elevator guide rail. Two pads 2 are made of nitrile rubber and are respectively filled between the left and right sides of the contact shoe liner 3 and the inner side of the fixed side plate 13. The pads 2 provide elastic support, ensuring that the contact shoe liner 3 is tightly fixed, and also absorb and dampen vibrations.

[0026] In some embodiments, chamfers are provided at the corners of the boot liner groove 31 on the contact boot liner 3, thereby improving the sliding stability of the guide boot.

[0027] A disassembly notch 15 is provided on the top or side of the fixed side plate 13. When it is necessary to replace the contact shoe liner 3 or the pad 2, maintenance personnel can reach through this notch to insert a tool, pry out the old part and press in the new part, which is very convenient.

[0028] Mounting holes 16 are provided at the mounting portions at both ends of the fixed mounting bracket 1. In this embodiment, the mounting holes 16 are preferably oblong holes, so that when the guide shoes are installed on the elevator car frame, the position of the guide shoes can be adjusted within a certain range to ensure that the alignment and clearance between them and the guide rails are optimal. Of course, the mounting holes 16 can also be designed as round holes according to actual needs.

[0029] The working principle of this utility model is as follows: the guide shoe is fixed to the elevator car frame through the assembly hole 16, so that the elevator guide rail is embedded in the shoe liner groove 31 of the contact shoe liner 3. When the elevator is running, the car slides along the guide rail through this guide shoe. Friction is generated between the contact shoe liner 3 and the guide rail, and the graphene material contained in it is precipitated during the friction to form a lubricating film, thus achieving self-lubrication. The rubber pads 2 on both sides ensure the stable clamping and operation buffering of the contact shoe liner 3.

[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
