[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] See also Figure 7 The speed limiter 20 triggering device provided in one embodiment of the present application includes a speed limiter brake wire 10, a speed limiter 20 and a controller 30. One end of the speed limiter brake wire 10 is connected to the speed limiter 20, and the other end of the speed limiter brake wire 10 is connected to the controller 30.

[0031] In a machine room-less elevator, the speed limiter 20 is installed at the top of the elevator shaft. Since the operator cannot approach the speed limiter 20, the speed limiter 20 triggering device of the present embodiment is provided with a speed limiter brake wire 10, so that the operator can remotely trigger the speed limiter 20 through the speed limiter brake wire 10 outside the elevator shaft.

[0032] Specifically, see Figure 3 and Figure 7 The speed limiter brake wire 10 includes a brake wire body 11, and the brake wire body 11 includes a core wire 111. Optionally, the core wire 111 is a steel wire. The core wire 111 has a first end 1111 and a second end 1112, the first end 1111 is connected to the speed limiter 20, and the second end 1112 is connected to the controller 30.

[0033] See also Figure 3 In this embodiment, both the first end 1111 and the second end 1112 are provided with wire ears.

[0034] In one embodiment, see Figure 1 , Figure 2 and Figure 7The speed limiter brake line 10 also includes a first fixing assembly 12. The first fixing assembly 12 includes a sleeve 121, a first element 122 and a second element 123. The sleeve 121 is fixed relative to the controller 30. The sleeve 121 is provided with a first mounting hole and a second mounting hole 1212 on both sides along its axial direction. The first element 122 is disposed in the first mounting hole, and the second element 123 is disposed in the second mounting hole 1212. The first element 122 and the second element 123 cooperate to clamp the core wire 111.

[0035] Optionally, the sleeve 121 is a hexagonal column, and the hexagonal column is provided with a through hole adapted to the core wire 111. During installation, the core wire 111 is arranged in the through hole of the hexagonal column. Of course, in other embodiments, the sleeve 121 can also be other components, which is not limited thereto.

[0036] When installing, refer to Figure 8 , the sleeve 121 is sleeved on the second end 1112 of the core wire 111, and the sleeve 121 is tightened so that the sleeve 121 is fixed relative to the controller 30. If the speed limiter 20 does not need to be triggered, the first element 122 and the second element 123 are tightened so that the first element 122 and the second element 123 cooperate to clamp the core wire 111, so that the operator cannot pull the core wire 111, thereby preventing misoperation. At the same time, compared with the control clamp, the space occupied by the speed limiter brake wire of this embodiment is small.

[0037] See also Fig. 9 If the speed limiter 20 needs to be triggered, the first element 122 and / or the second element 123 are released to unlock the core wire 111. Then, the core wire 111 is pulled away from the speed limiter 20 to trigger the speed limiter 20. For example, a screwdriver is inserted into the inner hole of the wire ear at the second end 1112, and the core wire 111 is pulled by the screwdriver.

[0038] In one embodiment, see Figure 4 The first mounting hole is a first threaded hole, and the first element 122 is disposed in the first threaded hole and is threadedly connected to the hole wall of the first threaded hole. Optionally, the first element 122 is a screw.

[0039] Further, see Figure 4 The second mounting hole 1212 is a second threaded hole, and the second element 123 is disposed in the second threaded hole and threadedly connected to the hole wall of the second threaded hole. Optionally, the second element 123 is a butterfly bolt.

[0040] When installing, refer to Figure 8If the speed limiter 20 does not need to be triggered, a screw is set in the first threaded hole and the screw is turned until the screw contacts the core wire 111, and a butterfly bolt is set in the second threaded hole and the butterfly bolt is turned until the butterfly bolt contacts the core wire 111. In this way, the screw and the butterfly bolt cooperate to clamp the core wire 111, thereby locking the core wire 111, so that the operator cannot pull the core wire 111, thereby preventing misoperation.

[0041] See also Fig. 9 If the speed limiter 20 needs to be triggered, the butterfly bolt is screwed in the opposite direction, the butterfly bolt is separated from the core wire 111, and the core wire 111 is unlocked. Then, the core wire 111 is pulled away from the speed limiter 20 to trigger the speed limiter 20 to act.

[0042] In one embodiment, see Figure 8 and Fig. 9 The first fixing assembly 12 further includes a first gasket 124. The first gasket 124 is disposed between the sleeve 121 and the side wall of the controller 30, one side of the first gasket 124 is in conflict with the sleeve 121, and the other side of the first gasket 124 is in conflict with the side wall of the controller 30. By disposing the first gasket 124 between the sleeve 121 and the side wall of the controller 30, under the action of the first gasket 124, the sleeve 121 can be tightly connected with the side wall of the controller 30 to prevent the sleeve 121 from loosening.

[0043] Further, see Figure 5 The first gasket 124 is provided with a first notch groove 1241, and the first notch groove 1241 extends from the middle of the first gasket 124 to the outer peripheral surface of the first gasket 124, so that the outer peripheral surface of the first gasket 124 has an opening. During installation, the brake wire body 11 enters the first notch groove 1241 through the opening, so that the first gasket 124 is installed on the core wire 111. During disassembly, the brake wire body 11 can be removed from the first notch groove 1241 through the opening. In this way, the disassembly and assembly of the first gasket 124 is convenient.

[0044] In one embodiment, see Figure 1 , Figure 3 and Figure 8 The brake wire body 11 further includes a speed limiter brake wire tube 112. The end of the speed limiter brake wire tube 112 close to the second end 1112 includes a first tube body 1121 and a second tube body 1122 connected to the first tube body 1121. The diameter of the first tube body 1121 is greater than the diameter of the second tube body 1122, and the second tube body 1122 is arranged close to the second end 1112. The first gasket 124 is arranged on the second tube body 1122.

[0045] Further, see Figure 1 , Figure 3 and Figure 8, the first fixing assembly 12 further includes a second gasket 125. The second gasket 125 is disposed on the second tube body 1122 and is located on the side of the side wall of the controller 30 away from the first gasket 124. One side of the second gasket 125 abuts against one end of the first tube body 1121 close to the second tube body 1122, and the other side of the second gasket 125 abuts against the side wall of the controller 30. During installation, the two sides of the second gasket 125 abut against the first tube body 1121 and the side wall of the controller 30 respectively, and under the action of the second gasket 125, the side wall of the controller 30 can be tightly connected with one end of the first tube body 1121 close to the second tube body 1122.

[0046] It should be noted that during installation, refer to Figure 8 and Fig. 9 The first gasket 124 and the second gasket 125 are respectively arranged on both sides of the side wall of the controller 30, and the two sides of the first gasket 124 are respectively in conflict with the sleeve 121 and the side wall of the controller 30, and the two sides of the second gasket 125 are respectively in conflict with one end of the first tube body 1121 close to the second tube body 1122 and the side wall of the controller 30, so that the first gasket 124 and the second gasket 125 cooperate to clamp the side wall of the controller 30, thereby fixing the speed limiter brake wire tube 112, the sleeve 121 and the side wall of the controller 30 to prevent misoperation.

[0047] Further, see Figure 5 The second gasket 125 is provided with a second notch groove 1251, and the second notch groove 1251 extends from the middle of the second gasket 125 to the outer peripheral surface of the second gasket 125, so that the outer peripheral surface of the second gasket 125 has an opening. During installation, the brake wire body 11 is placed into the second notch groove 1251 through the opening, so that the second gasket 125 is installed on the brake wire body 11. During disassembly, the brake wire body 11 can be removed from the second notch groove 1251 through the opening. In this way, the disassembly and assembly of the second gasket 125 is convenient.

[0048] In one embodiment, see Figure 1 and Figure 7 The speed limiter brake wire 10 further includes a bracket 13, the bracket 13 is fixed to the speed limiter 20, and the bracket 13 includes a first fixing portion 131 for fixing the brake wire body 11. In this way, the bracket 13 supports the brake wire body 11.

[0049] Further, see Figure 6 The first fixing portion 131 is provided with a third notch 1311, and the third notch 1311 extends to one side of the bracket 13 so that one side of the bracket 13 has an opening. In this embodiment, the third notch 1311 extends to the bottom of the bracket 13 so that the bottom of the bracket 13 has an opening.

[0050] During installation, the brake wire body 11 can be moved into the third notch groove 1311 through the opening. During disassembly, the brake wire body 11 can be moved out of the third notch groove 1311 through the opening. In this way, the disassembly and assembly of the brake wire body 11 is convenient.

[0051] In one embodiment, see Figure 1 and Figure 3 The end of the speed limiter brake wire tube 112 near the first end 1111 includes a third tube body 1123 and a fourth tube body 1124 connected to the third tube body 1123, the diameter of the third tube body 1123 is greater than the diameter of the fourth tube body 1124, and the fourth tube body 1124 is arranged near the first end 1111, and the fourth tube body 1124 passes through the third notch groove 1311. In this way, the speed limiter brake wire tube 112 is fixed.

[0052] Further, see Figure 1 , Figure 2 and Figure 7 The speed limiter brake wire 10 further includes a second fixing assembly 14. Optionally, the second fixing assembly 14 includes a nut, a gasket, etc. The second fixing assembly 14 is arranged on the fourth tube body 1124 and is located on the side of the first fixing portion 131 away from the third tube body 1123. The second fixing assembly 14 is used to lock the first fixing portion 131 and the speed limiter brake wire tube 112.
