Description

Technical Field

[0001] This utility model relates to the field of traction machines, and in particular to a gearless traction machine. Background Technology

[0002] Gearless traction machines are elevator drive devices that are directly driven by an electric motor to drive the traction sheave. They eliminate the traditional gear reduction mechanism and have advantages such as simple structure, high efficiency, energy saving, and low noise. They are widely used in modern elevator systems.

[0003] However, existing gearless traction machines cannot monitor the wear of the traction sheave in real time during operation, requiring manual measurement at regular intervals. This is not only troublesome but also has a certain degree of lag.

[0004] Therefore, it is essential to invent a gearless traction machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gearless traction machine with the following technical solution: A gearless traction machine includes a gearless traction machine body, a traction wheel, a base, a control box, and traction wire rope position detectors, wherein: the traction wheel is coaxially fixedly installed on the output end of the gearless traction machine body, the base is fixedly installed on the gearless traction machine body, the control box is detachably fixedly installed on the base, and two traction wire rope position detectors are evenly fixedly installed on the control box, with both traction wire rope position detectors located on both sides below the traction wheel;

[0006] The traction wire rope position detector includes an encoder and a drum. The encoder is fixedly installed inside the control box. One end of the drum is fixedly connected to the output end of the encoder, and the other end of the drum extends out of the control box.

[0007] The traction steel wire rope on the traction sheave is positioned between the two traction steel wire rope position detectors and is in rolling contact with the drums of the two traction steel wire rope position detectors;

[0008] Both encoders are electrically connected to a controller inside the control box, which is electrically connected to an external alarm and power supply via control lines.

[0009] The base has a through-hole extending from front to back, and the control box is plugged into the mounting cavity. Both rollers protrude from the front side of the mounting cavity.

[0010] Guide rails are fixedly installed on both sides inside the mounting cavity of the base, and the guide rails are slidably connected to the control box.

[0011] Two connection holes are evenly spaced on one side of the base away from the traction sheave. The two connection holes are located on both sides outside the mounting cavity and are fixedly connected to the control box.

[0012] The control boxes are provided with guide rail grooves on both sides corresponding to the guide rails, and the guide rail grooves are slidably connected to the corresponding guide rails.

[0013] The control box is fixedly installed on the rear side away from the roller with a fixing lug corresponding to the connection hole, and a fixing member is installed between the connection hole and the fixing lug.

[0014] The front side of the control box has two limiting holes corresponding to the rollers. One end of the roller extends out from the corresponding limiting hole, and the end of the roller extending out from the limiting hole is flush with the outer end face of the traction wheel.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] The overall design of this utility model allows the traction steel wire rope to drive the drum and rotate the encoder output end during the operation of the gearless traction machine. This triggers the encoder to generate a corresponding electrical signal, which determines whether there is wear between the traction steel wire rope and the traction sheave. If the encoder does not generate a corresponding electrical signal during the operation of the gearless traction machine, it can be determined that wear has occurred between the traction steel wire rope and the traction sheave, and the controller will trigger an alarm.

[0027] Example

[0028] Reference Figure 1-5 A gearless traction machine includes a gearless traction machine body 1, a traction sheave 2, a base 3, a control box 4, and traction wire rope position detectors 5. The output end of the gearless traction machine body 1 is coaxially fixedly mounted with the traction sheave 2. The base 3 is fixedly mounted on the gearless traction machine body 1. The control box 4 is detachably fixedly mounted on the base 3. Two traction wire rope position detectors 5 are evenly fixedly mounted on the control box 4. The two traction wire rope position detectors 5 are located on both sides below the traction sheave 2.

[0029] The traction wire rope position detector 5 includes an encoder 51 and a drum 52. The encoder 51 is fixedly installed inside the control box 4. One end of the drum 52 is fixedly connected to the output end of the encoder 51, and the other end of the drum 52 extends out from the control box 4.

[0030] Specifically, encoder 51 is a photoelectric encoder;

[0031] The traction steel wire rope on the traction sheave 2 is positioned between the two traction steel wire rope position detectors 5 and rolls in contact with the drums 52 of the two traction steel wire rope position detectors 5, so that when the traction steel wire rope rotates, it drives the drums 52 to rotate, thereby triggering the encoder 51, thereby determining that the traction steel wire rope is on the correct running trajectory and that the traction sheave 2 and the traction steel wire rope have not experienced significant wear.

[0032] Both encoders 51 are electrically connected to the controller inside the control box 4. The controller is electrically connected to the external alarm and power supply via the control line 6.

[0033] Specifically, the controller uses a microcontroller; the alarm can be a buzzer. When the gearless traction machine body 1 drives the traction wheel 2 to rotate the traction steel wire rope normally, the encoder 51 loses the signal, which can determine that the traction steel wire rope and traction wheel 2 are worn. Thus, the buzzer is triggered by the controller to remind relevant personnel.

[0034] In this embodiment, the base 3 has a through-hole 7 from front to back. The control box 4 is inserted and installed in the installation cavity 7 to provide the necessary installation space for the control box 4, reduce the overall installation area, and facilitate the separate disassembly and assembly of the control box 4 later. Both rollers 52 protrude from the front side of the installation cavity 7 so as to contact the outer side of the traction steel wire rope.

[0035] In this embodiment, guide rails 8 are fixedly installed on both sides inside the mounting cavity 7 of the base 3. The guide rails 8 are slidably connected to the control box 4 so as to ensure the stability of the control box 4 installed inside the mounting cavity 7 through the guide rails 8.

[0036] In this embodiment, two connecting holes 9 are evenly provided on the side of the base 3 away from the traction wheel 2. The two connecting holes 9 are located on both sides outside the mounting cavity 7, and the connecting holes 9 are fixedly connected to the control box 4.

[0037] Specifically, the connecting hole 9 can be an internal thread hole.

[0038] In this embodiment, guide rail grooves 10 corresponding to guide rails 8 are respectively provided on both sides of the control box 4. The guide rail grooves 10 are slidably connected to the corresponding guide rails 8 so as to limit the control box 4 and ensure the stability of the control box 4.

[0039] In this embodiment, a fixing lug 11 corresponding to the connection hole 9 is fixedly installed on the rear side of the control box 4 away from the roller 52, and a fixing member 12 is installed between the connection hole 9 and the fixing lug 11.

[0040] Specifically, the fastener 12 can be made of bolts to connect to the connection hole 9, and at the same time facilitate the separate disassembly and assembly of the control box 4 later.

[0041] In this embodiment, the front side of the control box 4 has two limiting holes 13 corresponding to the roller 52. One end of the roller 52 extends out from the corresponding limiting hole 13 so as to support and limit the roller 52 through the limiting hole 13, ensuring the stability of the roller 52 during rotation and avoiding pressure from acting directly on the output end of the encoder 51. The end of the roller 52 extending out from the limiting hole 13 is flush with the outer end face of the traction wheel 2.

[0042] Any technical solution designed by those skilled in the art using the technical solution described in this utility model, or inspired by the technical solution of this utility model, that achieves the above-mentioned technical effects, falls within the protection scope of this utility model. 。
