Description

Technical Field

[0001] The invention relates to the field of indoor elevators, in particular to an indoor elevator with an offset reel and anti-rope-slipping properties. Background Art

[0002] As a small household elevator, indoor elevators are widely used in villas with 2-3 floors. Considering that the space occupied by indoor elevators cannot be too large, indoor elevators generally set a kind of vertical guide rail without a shaft between the floors, and the driving device of the elevator moves with the elevator car. Specifically, a motor is used to drive a drum to retract and release two cables wound on two pulleys to realize the lifting and lowering of indoor elevators. In the existing indoor elevators, the two pulleys are fixed on the top of the car symmetrically, and the reel is set in the middle area of ​​the top of the car. Since the size of the car of a small household electric car is often small, and the output shaft of the motor is roughly at the reel, the motor needs to be installed on one side of the middle area of ​​the top of the car, which makes the installation space of the motor small and difficult to install the motor; moreover, when the cable is wound on the reel, since the reel has a certain length and the reel is close to the reversing pulley, the angle of the cable changes greatly, which makes it easy for the cable to move horizontally on the reel, and it is easy for the cable to get out of its normal position on the reel. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an anti-rope-slipping indoor elevator with an offset reel, which can provide sufficient installation space for the motor that drives the reel to rotate by offsetting the reel. Moreover, by arranging a rope groove and an anti-slipping member on the reel, the cable can be effectively prevented from moving horizontally on the reel, thereby ensuring the normal operation of the elevator and effectively solving the problems existing in the prior art.

[0004] In order to solve the above problems, the present invention provides an anti-slip rope indoor elevator with an offset reel, including a car with a central area on the top, including: a fixed beam, the middle section of the fixed beam is hinged to the central area of ​​the car top; two reversing pulleys are respectively arranged at both ends of the fixed beam; a lifting member, connected to the fixed beam, including a reel with a rope groove, and a cable wound around the reel, the reel is arranged between the two reversing pulleys, the cable extends upward after being reversing by the two reversing pulleys, and the reel deviates from the central area; an anti-slip member, connected to the fixed beam, having an anti-slip portion parallel to the axial direction of the reel, and the minimum distance between the anti-slip portion and the edge of the rope groove is less than the outer diameter of the cable.

[0005] Furthermore, the anti-slip portion is a substantially vertical plate-shaped structure, and the anti-slip component also includes a horizontal plate connected to the fixed beam and a rib plate arranged between the anti-slip portion and the horizontal plate.

[0006] Furthermore, one end of the cable extends from the upper side of the reel to the reversing pulley away from the reel, and the other end of the cable extends from the lower side of the reel to the reversing pulley close to the reel.

[0007] Furthermore, the anti-slip component is arranged on a side of the reel facing the reversing pulley away from the reel.

[0008] Furthermore, two anti-slip parts are provided, and the two anti-slip parts are respectively arranged on both sides of the reel; in the anti-slip part between the reversing pulley close to the reel and the reel, the anti-slip part is formed with a through groove for the cable to pass through.

[0009] Furthermore, the connecting line of the two reversing pulleys roughly divides the reel in half.

[0010] Furthermore, the axis of the drum is offset relative to a direction perpendicular to a line connecting the two reversing pulleys, so that the direction in which the cable enters the rope groove is the same as the inclination direction of the outer edge of the rope groove at the corresponding position.

[0011] Furthermore, the reversing pulley is hinged to the fixed beam around a vertical axis so that the reversing pulley can face the direction in which the cable enters the rope groove.

[0012] Furthermore, the vertical axis is coaxial with the vertically extending portion of the cable.

[0013] Furthermore, the lifting member also includes a gearbox and a motor connected to the fixed beam, the output shaft of the gearbox is coaxially connected to the reel, the input shaft of the gearbox is perpendicular to the axis of the reel, and the motor is arranged on the side of the gearbox facing the reversing pulley away from the reel.

[0014] The beneficial effect of the present invention is that the present invention provides an anti-rope-slipping indoor elevator with an offset reel, which can provide sufficient installation space for the motor that drives the reel to rotate by offsetting the reel, and by arranging a rope groove and an anti-slipping member on the reel, the cable can be effectively prevented from moving horizontally on the reel, thereby ensuring the normal operation of the elevator and effectively solving the problems existing in the prior art.

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0022] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0023] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0025] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] In the present invention, Figure 1-4 As shown in, there is provided an anti-slip rope indoor elevator with a reel offset, comprising a car 2 with a central area on the top, comprising: a fixed beam 1, the middle section of the fixed beam 1 is hinged to the central area of ​​the top of the car 2; two reversing pulleys 3, respectively arranged at both ends of the fixed beam 1; a lifting member, connected to the fixed beam 1, comprising a reel 4 with a rope groove 6, and a cable 5 wound around the reel 4, the reel 4 being arranged between the two reversing pulleys 3, the cable 5 extending upward after being reversing by the two reversing pulleys 3, and the reel 4 deviates from the central area; an anti-slip member 7, connected to the fixed beam 1, having an anti-slip portion 701 parallel to the axial direction of the reel 4, the minimum distance between the anti-slip portion 701 and the edge of the rope groove 6 being less than the outer diameter of the cable 5.

[0027] In order to facilitate the installation of the motor 9 driving the turntable to rotate, the indoor elevator of the present invention deviates the reel 4 from the central area, so that the reel 4 is close to one of the reversing pulleys 3, so that the motor 9 can be installed on the side of the reel 4 facing the other reversing pulley 3, thereby providing enough space for the installation of the motor 9. Since the reel 4 is offset from the midpoint of the line connecting the two reversing pulleys 3, the lengths of the cables 5 on both sides of the reel 4 are different, and then under the load of the car 2, the length deformation of the cables 5 on both sides of the reel 4 is different, which easily causes the car 2 to tilt. In order to solve this problem, a fixed beam 1 is provided to be rotatably connected to the car 2, and the reversing pulley 3 is provided on the fixed beam 1, and then when the length deformation of the cables 5 on both sides of the reel 4 is different, the fixed beam 1 can rotate relative to the car 2, and then the fixed beam 1 can be rotated to adapt to the difference in the length change of the cables 5 on both sides of the reel 4, and at the same time, the guide wheel of the car 2 cooperates with the middle of the slide rail of the elevator to keep the car 2 roughly balanced.

[0028] In order to allow the cable 5 to be wound on the drum 4 along the rope groove 6 and prevent the cable 5 from moving in the horizontal direction, the present invention provides a rope groove 6 on the drum 4. In order to further prevent the cable 5 from moving in the horizontal direction, the present invention also provides an anti-slip member 7, which can limit the cable 5 through the anti-slip portion 701, so that the cable 5 can be wound on the outside of the drum 4 along the rope groove 6, thereby enabling the car 2 to be raised and lowered in an orderly manner.

[0029] It should be noted that the central area of ​​the car 2 mentioned in the above content is the geometric center position of the top of the car 2. For example, as shown in the figure, the car is square, and the central area is the intersection of the diagonals of the top surface of the car.

[0030] In a preferred embodiment, the specific structure of the anti-slip member 7 can be set as follows: the anti-slip portion 701 is a roughly vertical plate-shaped structure, and the anti-slip member 7 also includes a horizontal plate 702 connected to the fixed beam 1, and a rib plate 703 arranged between the anti-slip portion 701 and the horizontal plate 702. Among them, by arranging the horizontal plate 702 on the fixed beam 1, the reel 4 can be rotated synchronously with the anti-slip member 7, and by arranging the rib plate 703, the structure of the anti-slip member 7 can be stabilized to prevent the anti-slip portion 701 from moving relative to the horizontal plate 702.

[0031] Of course, the anti-slip member 7 may also have other forms. For example, the anti-slip portion 701 may be an arc-shaped anti-slip portion 701 covering the outside of the reel 4, and a rope hole for the cable 5 to pass through is opened on the anti-slip portion 701.

[0032] To be more specific, Figure 1 and Figure 2 As shown, one end of the cable 5 extends from the upper side of the drum 4 to the reversing pulley 3 away from the drum 4, and the other end of the cable 5 extends from the lower side of the drum 4 to the reversing pulley 3 close to the drum 4. In this way, the maximum inclination angle of the cable 5 in the vertical direction can be reduced, and the force on the drum 4 in the vertical direction can be reduced.

[0033] exist Figure 2 In the embodiment shown, more specifically, the anti-slip member 7 is arranged on the side of the reel 4 facing the reversing pulley 3 away from the reel 4. Since the inclination angle of the cable 5 in the horizontal direction between the reel 4 and the reversing pulley 3 which is closer is larger, the cable 5 here is easier to move horizontally when winding. By such an arrangement, when the cable 5 at this location is wound on the reel 4, the anti-slip member 7 can be close to the place where the cable 5 enters the rope groove 6, which can have a good limiting effect.

[0034] Of course, in a replaceable embodiment, it can also be arranged like this, that is, there are two anti-slip parts 7, and the two anti-slip parts 7 are respectively arranged on both sides of the reel 4; in the anti-slip part 7 between the reversing pulley 3 close to the reel 4 and the reel 4, the anti-slip part 701 is formed with a through groove for the cable 5 to pass through.

[0035] More specifically, the line connecting the two reversing pulleys 3 roughly divides the reel 4 in half.

[0036] A further optimization is that the axis of the drum 4 is offset relative to a direction perpendicular to the line connecting the two reversing pulleys 3 so that the direction in which the cable 5 enters the rope groove 6 is the same as the inclination direction of the outer edge of the rope groove 6 at the corresponding position.

[0037] like Figure 4 As shown, the left reversing pulley 3 is closer to the drum 4, and the cable 5 led out of the left reversing pulley 3 is wound around the end of the drum 4 close to the gearbox 8. The drum 4 is offset and tilted to the left toward the end of the gearbox 8. By setting it in this way, the axis of the drum 4 is tilted, so that when the cable 5 at this location enters the rope groove 6, the angle between the cable 5 and the outer edge of the rope groove 6 is smaller, further preventing the cable 5 from escaping from the rope groove 6. Moreover, as Figure 4 As shown, by arranging the reel 4 in this way, when installing the motor 9, the end of the motor 9 away from the central area can be away from the fixed beam 1, which is not only suitable for installing a longer motor 9, but also convenient for installing the structural components on the top of the car 2.

[0038] It should be noted that, “the direction in which the cable 5 enters the rope groove 6 is the same as the inclination direction of the outer edge of the rope groove 6 at the corresponding position” means that the inclination direction of the cable 5 entering the rope groove 6 compared to the fixed beam 1 is the same as the inclination direction of the outer edge of the rope groove 6 at the corresponding position compared to the fixed beam 1, and does not mean that the inclination angle of the cable 5 when entering the rope groove 6 compared to the fixed beam 1 is the same as the inclination angle of the edge of the rope groove 6 at the corresponding position compared to the fixed beam 1.

[0039] A further optimization is that the reversing pulley 3 is hinged to the fixed beam 1 around a vertical axis so that the reversing pulley 3 can face the direction in which the cable 5 enters the rope groove 6. Specifically, as shown in the figure, the reversing pulley 3 has a pulley bracket, and the pulley bracket is rotatably connected to the solid beam. Through such an arrangement, when the reel 4 winds the cable 5, the reversing pulley 3 rotates, which can prevent the cable 5 from abutting against the wheel rim of the reversing pulley 3, and can also prevent the cable 5 from slipping out of the reversing pulley 3.

[0040] A further optimization is that the vertical axis is coaxial with the vertically extending portion of the cable 5. Thus, when the entire reversing pulley 3 rotates around the vertical axis, the upwardly extending direction of the cable 5 can rotate coaxially with the reversing pulley 3, preventing the upwardly extending portion of the cable 5 from moving in the horizontal direction, preventing the cable 5 from escaping from the reversing pulley 3, and maintaining the stability of the vertically extending portion of the cable 5.

[0041] To be more specific, the lifting member also includes a gearbox 8 and a motor 9 connected to the fixed beam 1, the output shaft of the gearbox 8 is coaxially connected to the reel 4, the input shaft of the gearbox 8 is perpendicular to the axis of the reel 4, and the motor 9 is arranged on the side of the gearbox 8 facing away from the reel 4.

[0042] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0043] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
