Description

Technical Field

[0001] This utility model relates to the field of elevator steel belt traction machine technology, and in particular to a frame for a villa elevator steel belt traction machine. Background Technology

[0002] As an important vertical transportation tool for residential homes, the stability, quietness, and reliability of the traction machine system are crucial for villa elevators. Currently, most mainstream villa elevators employ a technology combining a permanent magnet synchronous traction machine with flat steel belt traction. The traction machine assembly is fixed to the top of the shaft or machine room by a rigid frame constructed of high-strength steel, providing a supporting foundation for the system. In addition to the main traction sheave that drives the steel belt, this frame also includes at least one guide wheel, used to change the winding direction of the steel belt to form the necessary wrap angle. The guide wheel is mounted on a rigid support via an axle and bearing assembly, and is rigidly fixed to the frame using high-strength bolts. This is crucial for maintaining the precise relative position between the traction sheave and the guide wheel.

[0003] However, in actual use, this type of fixed-connection guide wheel is prone to problems due to abnormal conditions of the steel belt. When the steel belt experiences uneven tension, abnormal lubrication, or misalignment, the abnormal load will directly act on the guide wheel: uneven tension leads to uneven wear of the wheel groove; insufficient lubrication or contamination causes abnormal noise; severe misalignment or torsion will cause the "edge-biting" phenomenon of friction between the edge of the steel belt and the hub, which not only accelerates the damage of the steel belt, but may also cause bearing damage due to lateral force, leading to a chain of failures such as increased vibration and unstable operation.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a steel belt traction machine frame for a villa elevator, including a frame 3 set in the elevator shaft, an equipment body 2 set on the top of the frame 3, a controller 1 fixed in the elevator shaft and capable of controlling the equipment body 2 set on one side of the frame 3, and a guide wheel 4 that cooperates with the equipment body 2 set inside the frame 3.

[0031] The steel belt has a flat design and multiple steel wires arranged in a rectangular array inside, also known as (bearing core: a thin steel rope made of several high-strength carbon steel wires, which is embedded in the steel belt parallel to the length direction). The steel belt is close to the guide wheel 4 and the working surface of the wheel body 2. It is usually designed with regular stripes or toothed structure. These stripes are embedded in the grooves 503 of the guide wheel 4 and the wheel body of the equipment body 2, which can be used for limiting.

[0032] The working principle of an elevator steel belt traction system is based on friction transmission, relying on the static friction between the traction sheave groove and the polyurethane-coated steel belt for drive. The process begins with the passenger's floor selection command being input into the control box. The control system calculates the optimal operating curve and directs the inverter to output a three-phase power supply with adjustable voltage and frequency, driving the rotor of the permanent magnet synchronous traction machine to generate precise torque. This torque drives the traction sheave to rotate, and the high-friction grooves engage to pull the steel belt linearly. The guide wheel 4 in the system forcibly changes the direction of the steel belt, increasing the traction wrap angle to improve transmission efficiency and achieving a compact layout. Finally, the steel belt, suspended on the traction sheave, is connected to the car and counterweight at both ends, allowing them to move relative to each other under the forward and reverse rotation control of the traction sheave, thus completing a smooth, efficient, and quiet vertical transportation task.

[0033] Floating component 5 is disposed on the surface of guide wheel 4;

[0034] The floating component 5 also includes a connecting sleeve 501 disposed on the surface of the guide wheel 4, and a correction pad 508 is disposed inside the connecting sleeve 501.

[0035] However, if the steel belt experiences uneven tension, abnormal lubrication, or deviation, the abnormal load will directly act on the guide wheel 4. Uneven tension will cause uneven wear of the wheel groove, insufficient lubrication or contamination will cause abnormal noise, and severe deviation or torsion will cause the "edge chipping" phenomenon of friction between the steel belt edge and the wheel hub. In order to solve the above problems, the floating correction pad 508 in this embodiment can be used to compensate for the movement of the steel belt stripes during steel belt transmission, thereby resisting the pressure when the steel belt swings horizontally, reducing the swing force of the steel belt, and keeping the steel belt stable.

[0036] Example 2:

[0037] Reference Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the floating component 5 also includes a mating groove 513 formed on the surface of the connecting sleeve 501 for mating with the steel strip, and a correction pad 508 located in the mating groove 513. The inner wall of the mating groove 513 has a groove 503, and the correction pad 508 is a floating design.

[0039] The above design provides compensation space for the alignment pad 508 when it is squeezed by the steel strip, thereby offsetting the pressure of the steel strip.

[0040] Specifically, a movable plate 507 is fixedly connected to one side of the alignment pad 508, and a pressure pad 505 is fixedly connected to the side of the movable plate 507 near the inner wall of the groove 503. The side of the pressure pad 505 away from the movable plate 507 is fixedly connected to the inner wall of the groove 503.

[0041] The pressure pad 505 is located in the groove 503 and is made of rubber. Rubber has a certain plasticity and pressure resistance. Therefore, when the alignment pad 508 is pressed and squeezes the pressure pad 505, the pressure pad 505 can deform accordingly and absorb the pressure.

[0042] Specifically, a compensation hole 506 is provided in the middle of the pressure pad 505, and the cross-sectional shape of the compensation hole 506 is a vertical elliptical design.

[0043] By setting the compensation hole 506, the pressure absorption effect of the pressure pad 505 can be further improved, and the overall deformation resistance of the pressure pad 505 can also be enhanced.

[0044] Specifically, the groove 503 has a movable groove 514 inside, and the inner and outer diameters of the movable plate 507 are horizontally slidably connected to the inner wall of the movable groove 514.

[0045] By setting the movable groove 514, the movable plate 507 slides horizontally in the movable groove 514. When the correction pad 508 is pressed, the movable plate 507 can slide towards the pressure pad 505 in the movable groove 514. This not only prevents the correction pad 508 from shifting, but also reduces some of the pressure on the correction pad 508 by using friction.

[0046] Specifically, a compression ring 509 is fixedly connected to the surface of the alignment pad 508. The compression ring 509 is made of silicone and has an elliptical cross-sectional shape.

[0047] By setting the compression ring 509, which is a raised part on the surface of the correction pad 508, it can be embedded and attached to the stripes on the surface of the steel belt, thereby limiting the steel belt and improving the stability of the steel belt drive.

[0048] Example 3:

[0049] Reference Figures 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, the connecting sleeve 501 has a semi-circular arc design, and there are two connecting sleeves 501, which are concentric.

[0051] When subsequent personnel need to maintain the guide wheel 4, they only need to loosen the bolt 510 and remove the two connecting sleeves 501 from the surface of the guide wheel 4 to perform partial maintenance, which can effectively reduce the manpower and time consumed by the traditional maintenance method (removing the guide wheel 4 as a whole).

[0052] Specifically, threaded holes 512 are provided on the opposite sides of the two connecting sleeves 501, and mating holes 511 are provided on the surface of the guide wheel 4. Bolts 510 are threadedly connected between the two threaded holes 512 and the mating holes 511. The floating assembly 5 also includes a slot 504 provided on the surface of the guide wheel 4. A plate 502 is inserted into the slot 504, and the side of the plate 502 near the connecting sleeve 501 is fixedly connected to the connecting sleeve 501.

[0053] The bolts 510 can be used to fix the connecting sleeve 501 to the surface of the guide plate and act on the steel strip; the insert plate 502 and the slot 504 can guide the connecting sleeve 501 and assist in the alignment of the holes when the personnel install the connecting sleeve 501, thereby improving the efficiency of the personnel's operation.

[0054] In use, when the equipment body 2 is used in conjunction with the guide wheel 4 to pull the steel belt, the steel belt embedded in the groove 503 on the surface of the connecting sleeve 501 will first come into contact with the correction pad 508. The correction pad 508 is a floating design. When the steel belt swings or deviates from its track, the floating correction pad 508, together with the pressure pad 505, can provide horizontal resistance to the steel belt, thereby reducing the swing phenomenon of the steel belt and improving the stability of the steel belt transmission. In addition, when the guide wheel 4 is maintained by personnel, only the bolts 510 need to be unscrewed and the two connecting sleeves 501 need to be pulled out from the surface of the guide wheel 4 for partial maintenance, without the need for complete disassembly.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
