Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a forced-drive villa elevator. Background Technology

[0002] An elevator is a vertical lifting machine that primarily achieves vertical transportation through a main drive system. It consists of a box-shaped car and is used in multi-story buildings for transporting passengers or goods. As a vertical transportation tool, elevators have become essential and indispensable equipment in construction sites. To meet the needs of some users, villa elevators have developed rapidly, and the demand is constantly increasing. Because villa elevator shafts are generally smaller, the requirements for shaft space utilization are becoming increasingly stringent. In practical applications, elevator installation often faces challenges due to the limited top floor height, pit depth, and shaft dimensions.

[0003] The mainstream elevator types with high market acceptance mostly adopt a 2:1 suspension system. This type of elevator has a relatively complex structure, occupies a large space, and is not suitable for use in villas where shaft space is limited. In addition, the traction rope (steel belt or wire rope) in the main drive system of this type of elevator is generally wound on the main shaft at one end and connected to the car at the other end. The main shaft is a standard circle, and its position or structure for fixing the end of the steel belt has abrupt changes. When the steel belt is wound on it, some non-smooth transitions will occur due to the abrupt change in radius. After the elevator is running, these non-smooth transitions will cause corresponding vibrations during the operation. Moreover, the traction rope of this type of elevator is relatively long, and the number of turns on the main shaft is correspondingly increased, which exacerbates the vibration and affects the stability of the elevator operation. Utility Model Content

[0004] The present invention aims to provide a forced-drive villa elevator to overcome the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a forced-drive villa elevator, including a main drive mechanism, a reversing wheel assembly and a rope head fixing mechanism located on the top of the car. The main drive mechanism includes a drive component and a wheel. The drive component drives the main shaft to rotate. The wheel is fixedly connected to the main shaft. The outer side of the wheel is provided with a winding part for winding a steel strip. The winding part is a spiral curved surface. The pitch of the spiral curved surface is equal to the thickness of the steel strip. The steel strip is led out from the wheel, reversed to a horizontal position by the reversing wheel assembly, and then connected to the rope head fixing mechanism.

[0006] Furthermore, in the aforementioned forced-drive villa elevator, two wheel discs are symmetrically arranged on both sides of the drive unit, and the two wheel discs are fixed to both ends of the main unit's rotating shaft. Preferably, the wheel discs are fixedly connected to the main unit's rotating shaft via keys.

[0007] Furthermore, in the aforementioned forced-drive villa elevator, the wheel includes a wheel body and a pressure plate. The wheel body has a flat opening on its exterior, and the pressure plate is inlaid in the flat opening and detachably connected to the wheel body. The outer side of the pressure plate and the outer side of the wheel body are both curved surfaces, forming a winding section. A pressing groove is provided between the pressure plate and the flat opening on the exterior of the wheel body. One end of the steel strip is located in the pressing groove and is fixedly connected to the wheel by pressing with the pressure plate.

[0008] Furthermore, in the aforementioned forced-drive villa elevator, the connection point between the flat opening side and the winding section is the starting point of the steel strip winding on the winding section. The starting point of winding is provided with a rounded corner that transitions with the arc of the winding section, and the radius of the rounded corner is greater than the minimum bending radius of the steel strip.

[0009] Furthermore, in the aforementioned forced-drive villa elevator, two opposing baffles are provided on both sides of the wheel, with the two baffles protruding from the winding portion to form a limiting space for winding the steel strip. Preferably, the wheel body has grooves on both sides, and the baffles are annular, fitted outside the grooves. The baffles are fixedly connected to the wheel body by fasteners passing through the wheel body and the two baffles.

[0010] Furthermore, in the aforementioned forced-drive villa elevator, the inner side of the baffle is provided with a U-shaped pressure groove that is opposite to the flat opening. The bottom of the U-shaped pressure groove is an arc shape that matches the outer curved surface of the pressure plate. Both ends of the pressure plate extend into the U-shaped pressure grooves of the two baffles.

[0011] Furthermore, in the aforementioned forced-drive villa elevator, the winding portion of the wheel is manufactured by wire cutting.

[0012] Furthermore, in the aforementioned forced-drive villa elevator, the rope end fixing mechanism includes two rope end fixing components: rope end fixing component one and rope end fixing component two. The rope end fixing component one and rope end fixing component two are arranged side by side on the top of the car or are set opposite each other along a diagonal line on the top of the car.

[0013] Furthermore, in the aforementioned forced-drive villa elevator, the main drive mechanism is located at the bottom of the shaft, and a fixed pulley group is provided at the top of the shaft. The fixed pulley group is located on the support frame and includes two sets of fixed pulleys spaced apart along the axial direction of the main drive shaft. The steel belt led out from the wheel is led upward, passes through the fixed pulley group, and then led downward, is reversed to the horizontal by the reversing wheel group, and is then fixedly connected to the rope head fixing assembly.

[0014] Furthermore, in the aforementioned forced-drive villa elevator, the two steel belt traction paths are different. The steel belt mounted on one of the pulleys passes through at least one of a set of fixed pulleys and is connected to the first rope head fixing component. The steel belt mounted on the other pulley passes through at least one of a different set of fixed pulleys and is connected to the second rope head fixing component. The first rope head fixing component and the second rope head fixing component are arranged diagonally opposite each other along the top of the car.

[0015] Furthermore, in the aforementioned forced-drive villa elevator, the main drive mechanism is located at the top of the shaft, and the two steel belts have the same traction path. The steel belts drawn from the wheel are led downwards, reversed to the horizontal by the reversing wheel set, and then fixedly connected to the rope head fixing assembly. The first rope head fixing assembly and the second rope head fixing assembly are arranged side by side on the top of the car.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a 1:1 suspension system, which is simple, reliable, and space-saving, making it particularly suitable for villas with limited shaft space and ceiling height, thus greatly improving the utilization rate of shaft space. Furthermore, the 1:1 suspension system shortens the steel belt length, correspondingly reducing the number of winding turns, and allowing for a larger winding diameter and wheel diameter, thereby reducing steel belt wear and fatigue damage and extending the service life of the steel belt.

[0017] The main power mechanism of this utility model has better structural stability, is easy to disassemble and assemble, and is conducive to later maintenance; and the spiral curved surface of the winding wheel prevents abrupt changes in the winding radius of the steel belt, avoids elevator shaking caused by abrupt changes in winding, and improves the stability and comfort of elevator operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 like Figure 1-11As shown, a forced-drive villa elevator includes a main drive mechanism 1, a reversing wheel assembly 2 and a rope head fixing mechanism 3 located on the top of the car 7. The main drive mechanism 1 includes a drive component 11 and a wheel 12. The drive component 11 drives the main drive shaft 13 to rotate. The wheel 12 is fixedly connected to the main drive shaft 13. The outer side of the wheel 12 is provided with a winding part 121 for winding a steel belt 6. The steel belt 6 is led out from the wheel 12, reversed to the horizontal position by the reversing wheel assembly 2, and then connected to the rope head fixing mechanism 3.

[0022] In this embodiment, the reversing wheel assembly 60 converts the end of the steel belt 6 from vertical to horizontal, realizing the horizontal layout of the steel belt rope head structure. The layout is reasonable and compact, making clever use of the shaft plane space and effectively reducing the height occupation, especially reducing the requirements for the top floor height.

[0023] Among them, such as Figure 1-4 As shown, the drive unit 11 includes a reduction gearbox 111 and a servo motor 112. The reduction gearbox 11 is a gear reducer, which can increase the output torque and achieve stable and low-noise elevator lifting.

[0024] like Figure 1-4 As shown in Figure 7, two wheel discs 12 are provided, symmetrically arranged on both sides of the drive component 11, and the two wheel discs are fixed to both ends of the main unit shaft 13. Specifically, the wheel discs 12 are fixedly connected to the main unit shaft 13 by keys, which is simple and convenient to install, but it is not limited to this; it can also be connected by pins, fasteners, etc. The wheel discs 12 are located at both ends of the drive component 11 and the main unit shaft 13, which improves the structural stability of the main unit power mechanism and facilitates the disassembly and assembly of the wheel discs, which is beneficial for later maintenance.

[0025] To improve the rotational stability of the wheel, support bearing seats 14 can be set at both ends of the main shaft 13. By setting the support bearing seats 14, the load on the main shaft 13 can be reduced, and the wheel on both sides of the drive component 11 can be better supported, thereby improving the rotational stability of the wheel.

[0026] like Figure 1-6 As shown, the rope end fixing mechanism 3 includes two rope end fixing components: rope end fixing component one 301 and rope end fixing component two 302. Rope end fixing component one 301 and rope end fixing component two 302 are arranged side by side on the top of the car 7 or are arranged opposite each other along a diagonal of the top of the car 7.

[0027] like Figure 5-6As shown, the rope end fixing assembly includes a support rod 32 that passes through the fixing seat 31. The fixing seat 31 is fixed to the top of the car 7. A rope threading block 37 is installed at the end of the support rod 32. The rope threading block 37 and the reversing wheel assembly 2 are located on the same side of the fixing seat 31. A through opening 371 is opened on the rope threading block 37. A steel belt 6 that is horizontally led out from the reversing wheel assembly 2 extends into the small end of the opening 371 and extends out from the large end. Then, it is folded back at the large end and extends out from the small end. A steel belt clip 38 is installed at the end of the steel belt 6 that extends out from the small end. A wedge block 39 is pressed between the double-layer steel belts 6 inside the rope threading block 37. The wedge block 38 is adapted to the shape of the cavity of the opening.

[0028] In actual operation, the steel strip 6 is inserted into the small end of the rope-threading block 37 and extended out of the large end. The steel strip 6 wraps around the wedge block 39 from the large end and is then inserted back into the opening 371 of the rope-threading block 37. The end of the steel strip 6 extends out of the small end and is tightened before installing the steel strip clamp 38. The wedge surface between the wedge block 39 and the opening 371 is pressed tightly against the steel strip 30, thus completing the installation of the end of the steel strip 6 on the rope head fixing assembly.

[0029] On the support rod 32 located on the other side of the fixing base 300, opposite to the rope-threading block 37, a washer 34, an elastic element 33, and another washer 34 are sequentially fitted, and a double locking nut 33 is threaded and locked; a pin 36 is inserted radially on the support rod 32 adjacent to the outer side of the locking nut 33; the elastic element 33 on the support rod 32 provides a buffer elasticity for the rope end fixing assembly that holds the end of the steel strip 30; the pin 36 is used to prevent the locking nut 33 from falling off.

[0030] In this embodiment, the steel strip clamp 38 can be a structure with opposite fasteners interlocking to prevent the steel strip 6 from loosening; the end of the support rod 32 is threadedly assembled with the rope-threading block 37; a through groove is provided on the wedge block 39, and a locking pin is installed horizontally through the rope-threading block 37 and the through groove to prevent the wedge block 39 from disengaging from the rope-threading block 37.

[0031] In one embodiment, such as Figure 1-2 As shown, the main drive mechanism 1 is located at the bottom of the shaft, and a fixed pulley group 4 is located at the top of the shaft. The fixed pulley group 4 is located on the support frame 5 and includes two sets of fixed pulleys spaced apart along the axis of the main drive shaft 13. The steel belt 6 led out from the wheel 12 is led upward, passes through the fixed pulley group 4, and then led downward, passes through the reversing wheel group 2 to be reversed to the horizontal, and is then fixedly connected to the rope head fixing assembly.

[0032] In this embodiment, the two steel belts 6 have different traction paths. The steel belt 6 wound around one of the pulleys 12 passes through at least one of the fixed pulleys in a set of fixed pulleys and is connected to the rope end fixing component 301. The steel belt 6 wound around the other pulley 12 passes through at least one of the fixed pulleys in another set of fixed pulleys and is connected to the rope end fixing component 302. The rope end fixing component 301 and the rope end fixing component 302 are arranged diagonally opposite each other on the top of the car 7. Correspondingly, the reversing wheel group 2 is also arranged diagonally on the top of the car 7, so that the steel belt is connected to the corner of the car at a diagonal angle, forming a more stable connection structure. The elevator structure of this embodiment is simple and the operation is stable.

[0033] In this embodiment, a guide wheel 15 is provided diagonally above the wheel 12. The axis of the guide wheel 15 is parallel to the axis of the wheel 12 and is fixed to the drive member 11 by the wheel seat 151. The steel belt 6 wound on the wheel 12 is led out towards the car 7 after passing through the guide wheel 15, limiting the lead-out position of the steel belt 6 and ensuring smooth operation of the steel belt.

[0034] In another embodiment, such as Figure 3-4 As shown, the main drive mechanism 1 is located at the top of the shaft. The two steel belts 6 have the same traction path. The two steel belts 6, drawn from the wheel 12, are led downwards, reversed to the horizontal by the reversing wheel group 2, and then fixedly connected to a rope end fixing assembly. Rope end fixing assembly one 301 and rope end fixing assembly two 302 are arranged side by side on the top of the car 7. The elevator structure of this embodiment is simpler, especially reducing the requirements for the length or width of the shaft, occupying less space, and operating stably.

[0035] This invention employs a 1:1 suspension system, which is simple, reliable, and space-saving, making it particularly suitable for villas with limited shaft space and ceiling height, thus greatly improving the utilization rate of shaft space. Furthermore, the 1:1 suspension system shortens the steel belt length, correspondingly reducing the number of winding turns. While maintaining the same diameter after winding, the winding diameter and wheel diameter can be increased accordingly, reducing steel belt wear and fatigue damage, and extending the service life of the steel belt.

[0036] In the above structure, such as Figure 10-11 As shown, the winding section 121 is a spiral surface, and the pitch of the spiral surface is equal to the thickness of the steel strip 6. A spiral is a curve that unfolds in a vortex shape within a plane. It typically rotates around a central point and gradually moves away from the central point as the rotation angle increases, exhibiting a gradually spreading trend in its shape. The distance of any point on it relative to the central point is: r = r0 + (P / 360) * θ Among them, such as Figure 11As shown, r0 is the distance between the starting point and the center point, P is the pitch, and θ is the cumulative rotation angle. The pitch P is taken to be equal to the steel strip thickness. Figure 11 The double-dotted line represents a circle with radius r0. The spiral surface of the winding section gradually moves away from the center point as the rotation angle increases, and the distance between it and the circle with radius r0 gradually increases. In this embodiment, the steel strip is 3mm, i.e., P=3mm. When the steel strip returns to the starting point after one turn, its radius r=r0+P, that is, the value of r is exactly 3mm larger than the steel strip wound in the first layer. At this time, continuing to wind the steel strip for the second turn will not result in any sudden change in radius value. Regardless of how many layers are wound, the radius change of all steel strip windings follows the above formula, which is a linear gradual value without sudden changes, avoiding elevator shaking and ensuring stable elevator operation.

[0037] like Figure 8-11 As shown, the roulette wheel 12 includes a roulette wheel body 122 and a pressure plate 123. The roulette wheel body 122 has a flat opening 1221 on its outside. The pressure plate 123 is inlaid in the flat opening 1221 and is detachably connected to the roulette wheel body 122. The outer side of the pressure plate 123 and the outer side of the roulette wheel body 122 are both curved surfaces, forming a winding part 121. A pressing groove 125 is provided between the pressure plate 123 and the flat opening 1221 on the outside of the roulette wheel body 122. One end of the steel strip 6 is located in the pressing groove 125 and is fixedly connected to the roulette wheel 12 by pressing with the pressure plate 123.

[0038] like Figure 9-11 As shown, the connection point between the flat opening 1221 and the winding section 121 is the starting point of the steel strip 6 winding on the winding section 121. The starting point of the winding has a rounded corner 1222 that transitions smoothly with the arc of the winding section 121. The radius of the rounded corner 1222 is greater than the minimum bending radius of the steel strip 6. The steel strip 6 is wound on the wheel 12. Compared to being directly wound on the main shaft, the outer diameter of the winding is increased. In this embodiment, the ratio of the outer diameter of the wheel 12 to the outer diameter of the main shaft 13 is greater than 2:1, that is, the outer diameter of the wheel 12 is greater than twice the outer diameter of the main shaft 13. The increased outer diameter of the winding reduces the restriction on the bending radius of the steel strip, expanding the range of steel strip applications. Furthermore, the increased outer diameter of the winding allows the radius of the rounded corner 1222 at the starting point of the winding to increase accordingly, making the arc radius greater than the minimum bending radius of the steel strip. This avoids the steel strip bulging caused by a large bending angle during the initial winding, improving the stability and comfort of the elevator operation. In addition, increasing the outer diameter of the winding can increase the running speed of the steel belt, thereby increasing the elevator's lifting speed.

[0039] like Figure 8-9As shown, in order to prevent the steel belt from deviating during the lifting and lowering of the car, two baffles 124 are provided on both sides of the wheel 12. The two baffles 124 protrude from the winding part 121, forming a limiting space for winding the steel belt 6, providing guidance and limiting for the winding of the steel belt, preventing the steel belt from deviating during operation, and effectively ensuring the stability and smoothness of the steel belt winding.

[0040] The main body 122 of the wheel has grooves on both sides. The baffle 124 is annular and is fitted outside the grooves. The baffle 124 is fixedly connected to the main body 122 of the wheel by fasteners passing through the main body 122 of the wheel and the two baffles 124. The installation is simple and convenient, and it can improve the strength and stability of the overall structure of the wheel 12.

[0041] In addition, such as Figure 8-9 As shown, the inner side of the baffle 124 is provided with a U-shaped pressure groove 1241 opposite to the flat opening 1221. The bottom of the U-shaped pressure groove 1241 is an arc shape that matches the outer curved surface of the pressure plate 123. Both ends of the pressure plate 123 extend into the U-shaped pressure grooves 1241 of the two baffles 124. By setting the U-shaped pressure groove 1241, the pressing strength of the pressure plate 123 on the steel strip 6 can be improved, ensuring the stability of the connection between the steel strip 6 and the wheel 12.

[0042] Furthermore, the winding portion 121 of this invention is manufactured by wire cutting. The specific processing method includes the following steps: S1, wire cutting the spiral curved surface of the winding portion 21; S2, wire cutting the pressing groove 25 to cut the wheel 2 into the wheel body 22 and the pressure plate 23. Since the curved surface cannot be machined by turning, it requires four-axis or five-axis CNC machining, which is difficult and costly. Compared with four-axis or five-axis CNC machining, wire cutting greatly reduces the processing difficulty, reduces the processing cost, improves the feasibility of the process, and is conducive to implementation and application.

[0043] The main power mechanism of this utility model has better structural stability, is easy to disassemble and assemble, and is conducive to later maintenance; and the spiral curved surface of the winding wheel prevents abrupt changes in the winding radius of the steel belt, avoids elevator shaking caused by abrupt changes in winding, and improves the stability and comfort of elevator operation.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
