Description

Technical Field

[0001] The present invention relates to elevator technology, and relates to a machine-roomless elevator. Background Art

[0002] For common machine-roomless elevators, the traction machine is arranged at the top of the hoistway and supported by guide rails, which brings the following two problems. First, when the car carrying the balance load is stuck in the hoistway and emergency rescue of the passengers in the car is required, the car cannot be moved only by electric brake release. It is necessary to hang heavy weights on the compensation or stack heavy weights on the car top. Searching for, carrying and hanging heavy weights not only takes time but also is inconvenient to operate. Therefore, the trapped passengers in the car cannot be rescued in a timely and fast manner. Second, since the guide rails bear a large load, permanent deformation is likely to occur, which affects the riding comfort in the car.

[0003] CN2535386Y discloses a machine-roomless elevator, in which the traction machine and the control cabinet are respectively installed on the car frame and the car top.

[0004] If in the traditional way, the control cabinet is powered by the trailing cable, which requires the trailing cable to transmit the power supply signal, increasing the manufacturing difficulty of the trailing cable. Once the power line fails under repeated high-speed bending, it is easy to cause the elevator to stop suddenly at high speed, reducing the riding experience, and even seriously harming the personal safety of passengers. The control cabinet using DC power supply can avoid the above problems, but it will face the problem of battery life of DC power supply. Summary of the Invention

[0087] The junction box 21 is fixed at a position in the middle or at the top of the hoistway 1;

[0091] Preferably, a plurality of junction boxes 21 are fixed at the middle and top positions of the hoistway 1;

[0092] The junction boxes 21 are connected by wire, and the junction boxes 21 communicate with the control cabinet wirelessly, and each time the control cabinet only communicates with the nearest junction box.

[0093] For the machine-roomless elevator of Embodiment 1, the traction machine 2 and the control cabinet 3 are fixedly installed on the top of the car 30b. There is no need to hang counterweights on the compensation or stack counterweights on the car top. The car 30b can be moved only by relying on electric brake release, which is convenient for rescuing trapped passengers in the car in a timely and fast manner, and avoids affecting the riding comfort in the car due to permanent deformation of the car guide rail under a large load; the control cabinet powered by direct current can be automatically charged to improve the endurance; it can ensure the communication quality between the control cabinet 3 and the landing call devices 23 on each floor and does not require a trailing cable.

[0094] Embodiment 2

[0095] Based on Embodiment 1, as Figure 3 、 Figure 4 shown, the machine-roomless elevator further includes a charging structure;

[0096] The charging structure includes a striking plate 41, a support member 56, a gear pair 53, an electrode mounting arm 52, a charging power electrode 51 and a swing arm 54;

[0097] The striking plate 41 is installed on the car 30b or its accessories and moves up and down in the hoistway along with the car 30b;

[0098] The support member 56 is installed on the car guide rail or the hoistway wall;

[0099] The gear pair 53 is installed on the support member 56;

[0100] The gear pair 53 includes a first rotating shaft 53a, a first gear 53b, a second rotating shaft 53c, and a second gear 53d;

[0101] The axis of the first rotating shaft 53a is in the vertical direction, and the first gear 53b is coaxially fixed to the first rotating shaft 53a;

[0102] The axis of the second rotating shaft 53c is in the horizontal direction, and the second gear 53d is coaxially fixed to the second rotating shaft 53c;

[0103] The second gear 53d meshes with the first gear 53b;

[0104] The charging power supply electrode 51 is fixed to one end of the electrode mounting arm 52;

[0105] The other end of the electrode mounting arm 52 is fixedly connected to the first rotating shaft 53a, so that the electrode mounting arm 52 rotates with the first rotating shaft 53a;

[0106] One end of the swing arm 54 is provided with a swing arm roller 54b that can rotate freely;

[0107] The other end of the swing arm 54 is fixedly connected to the second rotating shaft 53c, so that the rotation of the swing arm 54 can drive the second rotating shaft 53c to rotate in the same direction;

[0108] In the natural state, the swing arm 54 is in the initial position A, which is in the vertical direction and in the vertical movement direction of the striking plate 41;

[0109] When the striking plate 41 moves vertically with the car 30b and contacts the swing arm 54, the swing arm 54 can be pushed to the working position A', so that the other end of the swing arm 54 is away from the car.

[0110] Preferably, the support member 56 is located at the top floor terminal 22a or the bottom floor terminal 22b.

[0111] Preferably, the accessory includes the car frame 30a.

[0112] Embodiment III

[0113] Based on the machine-roomless elevator of Embodiment II, as Figure 4 shown, the support member 56 is located at the top floor terminal 22a;

[0114] The lower end of the swing arm 54 is provided with a swing arm roller 54b that can rotate freely;

[0115] The upper end of the swing arm 54 is fixedly connected to the second rotating shaft 53c, so that the rotation of the swing arm 54 can drive the second rotating shaft 53c to rotate in the same direction;

[0116] When the car 30b is at a position other than the top floor terminal 22a, the electrode mounting arm 52 is in the initial position A, and at this time the charging power supply electrode 51 is located between the car 30b and the shaft wall 1;

[0117] When the strike plate 41 moves upward with the car 30b to the top terminal station 22a, it forces the swing arm 54 to rotate forward to the working position A', thereby driving the second rotating shaft 53c and the second gear 53d to rotate forward, and then driving the first gear 53b and the first rotating shaft 53a to rotate on a plane. The first rotating shaft 53a drives the electrode mounting arm 52 to rotate, so that the charging power supply electrode 51 rotates from the initial position A to the working position A', and is located directly above the energy storage device charging electrode 3a on the control cabinet 3 and is connected to the energy storage device charging electrode 3a.

[0118] Preferably, the second gear 53d is an incomplete gear. After the charging power supply electrode 51 rotates counterclockwise from the initial position A to the working position A', when the car 30b continues to rise subsequently, the strike plate 41 forces the swing arm 54 to continue to rotate forward, but the second gear 53d cannot continue to drive the first gear 53b to rotate. Eventually, the charging power supply electrode 51 stays at the working position A' waiting for the energy storage device charging electrode 3a, and the charging power supply electrode 51 is coupled with the energy storage device charging electrode 3a as the car 30b continues to rise, so as to charge the energy storage device in the control cabinet 3.

[0119] For the machine-roomless elevator of Embodiment 3, an energy storage device is arranged in the control cabinet 3, and the energy storage device supplies power to the traction machine 2; a charging device is arranged at the top terminal station 22a to charge the energy storage device. When the elevator works, the energy storage device supplies power to the traction machine 2. When the elevator car stops at the top terminal station 22a, the charging device charges the energy storage device to ensure its endurance. Only when the set charging conditions are met can the elevator car 30b be charged after running to the top terminal station 22a.

[0120] Embodiment 4

[0121] Based on the machine-roomless elevator of Embodiment 3, as Figure 5 、 Figure 6 shown, the charging structure further includes a strike plate driving device 42;

[0122] The strike plate driving device 42 is installed on the car 30b or its accessories and runs up and down in the hoistway with the car 30b;

[0123] The strike plate 41 is fixedly connected to the strike plate driving device 42 through a connecting member 43;

[0124] The strike plate driving device 42 is signal-connected to the control cabinet 3, and drives the connecting member 43 to send the strike plate 41 to the initial position C or the working position C' according to the instruction sent by the control cabinet.

[0125] When the striking plate 41 is in the initial position C, the striking plate 41 is vertically staggered in space from the swing arm 54 and the swing arm roller 54b. Even when the car 30b is at the top terminal station 22a, the striking plate 41 cannot force the swing arm 54 to rotate. Therefore, the charging power supply electrode 51 remains in its initial position A, prohibiting the charging of the energy storage device in the control cabinet 3.

[0126] When the striking plate 41 is in the working position C', during the process of the car 30b rising to reach the top terminal station 22a, the striking plate 41 can be coupled with the swing arm roller 54b and force the swing arm 54 to rotate, so that the charging power supply electrode 51 rotates to the working position A' to charge the energy storage device in the control cabinet 3.

[0127] For the machine-roomless elevator of the fourth embodiment, when the preset charging conditions (such as set time, elevator standby, insufficient power in the control cabinet, etc.) are met, the control cabinet 3 sends a working instruction to the striking plate driving device 42. The striking plate driving device 42 pushes the striking plate 41 from the initial position C to the working position C' through the connecting member 43, and then controls the elevator car to run towards the top terminal station 22a to complete the charging process of the energy storage device in the control cabinet 3.

[0132] The driving motor 41a is signal-connected to the control cabinet 3, and drives the striking plate rotating shaft 41c according to the working instruction sent by the control cabinet 3 to drive the first swing arm 41d to rotate forward, so that the first swing arm 41d moves away from the car 30b or its accessories to reach the working position B';

[0133] When the first swing arm 41d is in the working position B', during the upward movement of the car 30b, the first swing arm 41d will force the swing arm 54 to rotate forward to charge the energy storage device in the control cabinet 3.

[0134] Preferably, the striking plate 41 further includes a coil spring 41b;

[0135] The coil spring 41b is used to force the striking plate rotating shaft 41c to rotate reversely to drive the first swing arm 41d to rotate reversely when the driving motor 41a does not work, so that the first swing arm 41d approaches the car 30b or its accessories and returns to the initial position B.

[0136] When the first rocker arm 41d is in the initial position B, it and the swing arm 54 are both in the vertical state, and they are vertically offset in space.

[0138] One end of the second rocker arm 41e is pivotally installed on the car 30b or its accessories and is located below the striking plate rotating shaft 41c, and the other end is slidably connected to the first rocker arm 41d.

[0139] In the machine-roomless elevator of Embodiment 5, the first rocker arm 41d has two states, the initial position B and the working position B'. When the driving motor 41a works, it can drive the first rocker arm 41d to rotate through the rotating shaft 41c; when the preset charging conditions (such as the set time, the elevator is on standby, the control cabinet has insufficient power, etc.) are met, the control cabinet 3 sends a working instruction to the driving motor 41a, and the driving motor 41a drives the first rocker arm 41d located at the initial position B to rotate counterclockwise to its working position B', and then the elevator runs towards the top terminal station 22a to complete the charging process.

[0140] Embodiment 6

[0141] Based on Embodiment 1, the machine-roomless elevator further includes a charging structure;

[0142] As Figure 8 、 Figure 9 shown, the charging structure includes a support member 56, an installation arm driving device 60, an electrode installation arm 52, and a charging power supply electrode 51;

[0143] The support member 56 is installed on the car guide rail or the hoistway wall, and is located at the top terminal station 22a or the bottom terminal station 22b;

[0144] The installation arm driving device 60 is installed on the support member 56;

[0145] The installation arm driving device 60 includes a third rotating shaft 60a and an arm motor 60b;

[0146] The charging power supply electrode 51 is fixed to one end of the electrode installation arm 52;

[0147] The other end of the electrode installation arm 52 is connected to the third rotating shaft 60a, so that the electrode installation arm 52 rotates with the third rotating shaft 60a;

[0148] The electrode installation arm 52 has two positions, the initial position is A, and the working position after rotation is A';

[0149] The installation arm driving device 60 is signal-connected to the control cabinet 3. When receiving a working instruction sent by the control cabinet 3, it drives the third rotating shaft 60a to drive the electrode installation arm 52 to rotate forward so that the electrode installation arm 52 reaches the working position A', making the charging power supply electrode 51 exactly above the energy storage device charging electrode 3a on the control cabinet 3. The charging power supply electrode 51 is connected to the energy storage device charging electrode 3a, thus completing the charging process. When not receiving a working instruction sent by the control cabinet 3, it drives the third rotating shaft 60a to drive the electrode installation arm 52 to rotate in reverse away from the energy storage device charging electrode 3a to reach the initial position A, prohibiting charging the energy storage device in the control cabinet 3.

[0150] For the machine-roomless elevator of Embodiment 6, when the preset charging conditions (such as set time, elevator standby, insufficient power in the control cabinet, etc.) are met, the control cabinet 3 sends a working instruction to the arm motor 60b. The arm motor 60b drives the third rotating shaft 60a to rotate, thereby sending the charging power supply electrode 51 from the initial position A to the working position A'. Subsequently, the elevator car 30b runs towards the top terminal station 22a until the energy storage device charging electrode 3a and the charging power supply motor 51 are coupled with each other, realizing charging the control cabinet 3.

[0151] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
