Technical Field

[0001] This utility model relates to the field of elevators, and in particular to a safety device for villa elevators. Background Technology

[0002] Elevator safety devices are a crucial part of elevator systems, and their main function is to ensure the safety of passengers and goods.

[0003] The safety clamp is a very important elevator safety device.

[0004] Safety clamps: To prevent accidents caused by sudden car falls due to broken hoisting wire ropes, slippage in the rope groove, or other reasons, safety clamps that can simultaneously cut off the control power and stop the car from falling should be installed on the car. Cars without safety clamps must not be used for passenger transport.

[0005] However, existing elevator safety brakes have a limited contact area with the elevator guide rails during braking, which increases the braking distance and poses a significant safety hazard.

[0006] Therefore, it is essential to invent a safety device for villa elevators. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] Example

[0033] Reference Figure 1-5A safety device for a villa elevator includes a bracket 1 and a support plate 2. The support plate 2 is fixedly installed on the bracket 1 via a connector 16. A wedge-shaped groove 9 is provided on the support plate 2. A wedge-shaped friction block 3 and a wedge-shaped friction block 4 are slidably installed in the wedge-shaped groove 9. A pull rod 7 is fixedly installed at the top of the wedge-shaped friction block 4 so as to connect with the elevator counterweight wire rope through the pull rod 7. In this way, when the elevator stalls, the counterweight pulls the pull rod 7 through the wire rope, so that the wedge-shaped friction block 3 and the wedge-shaped friction block 4 can contact and clamp with the vertical side of the T-shaped rail 17. At the same time, one end of the wedge-shaped friction block 3 14 will extend from the wedge-shaped friction block 3 and the wedge-shaped friction block 4 to contact and clamp with the lateral side of the T-shaped rail 17, thereby increasing the contact area with the T-shaped rail 17 and achieving braking more quickly.

[0034] In this embodiment, each of the wedge-shaped friction block 3 and the wedge-shaped friction block 4 has a through hole, and a wedge-shaped friction block 3 14 is slidably installed in each of the through holes of the wedge-shaped friction block 3 and the wedge-shaped friction block 2 4 so that during the normal operation of the elevator, one end of the wedge-shaped friction block 3 14 is hidden in the through hole to prevent the wedge-shaped friction block 3 14 from contacting the T-shaped rail 17. The wedge-shaped friction block 3 14 is arranged perpendicularly to the corresponding wedge-shaped friction block 3 and the wedge-shaped friction block 2 4.

[0035] In this embodiment, a wedge-shaped guide rail 11 corresponding to the wedge-shaped friction block 3, such as a T-shaped guide rail or a cross-shaped guide rail, is fixedly installed in the wedge-shaped groove 9 of the support plate 2.

[0036] In this embodiment, one end of the wedge-shaped friction block 3 is provided with a wedge-shaped guide groove 15 corresponding to the wedge-shaped guide rail 11, such as a T-shaped groove or a cross-shaped groove. The wedge-shaped friction block 3 is slidably connected to the corresponding wedge-shaped guide rail 11 through the wedge-shaped guide groove 15. By setting the wedge-shaped guide rail 11 and the wedge-shaped guide groove 15, the wedge-shaped friction block 3 14 can be limited. Under normal circumstances, it prevents the end of the wedge-shaped friction block 3 14 away from the wedge-shaped guide rail 11 from accidentally protruding from the through hole. At the same time, when braking is required, the end away from the wedge-shaped guide rail 11 can be made to protrude from the through hole and contact the T-shaped rail 17 under the movement of the wedge-shaped friction block 3 and the wedge-shaped friction block 4.

[0037] In this embodiment, a limiting groove 10, such as a T-shaped groove or a cross-shaped groove, is provided on both sides of the wedge-shaped groove 9 of the support plate 2 to limit the wedge-shaped friction block 3 and the wedge-shaped friction block 4, ensuring the stability between the wedge-shaped friction block 3 and the wedge-shaped friction block 4 and the wedge-shaped groove 9, and avoiding separation. The wedge-shaped friction block 3 and the wedge-shaped friction block 4 are slidably connected to the corresponding limiting groove 10.

[0038] In this embodiment, an upper anti-detachment plate 6 is fixedly installed on the top of the support plate 2 to limit the wedge-shaped friction block 3 and the wedge-shaped friction block 4 and prevent them from detaching from the support plate 2 under the pull of the pull rod 7. The upper anti-detachment plate 6 has a notch corresponding to the pull rod 7, and the pull rod 7 slides out from the notch.

[0039] In this embodiment, two reinforcing plates 5 are fixedly installed on the support plate 2. The two reinforcing plates 5 are distributed on both sides of the wedge groove 9. The first wedge friction block 3 and the second wedge friction block 4 are located between the corresponding reinforcing plate 5 and the wedge groove 9. The first wedge friction block 3 and the second wedge friction block 4 are slidably connected to the corresponding reinforcing plate 5 so as to limit the first wedge friction block 3 and the second wedge friction block 4 through the reinforcing plate 5, enhance the stability of the first wedge friction block 3 and the second wedge friction block 4 in the wedge groove 9, and prevent the first wedge friction block 3 and the second wedge friction block 4 from coming out of the wedge groove 9.

[0040] In this embodiment, wear-resistant plates 13 are fixedly installed on the opposing surfaces of wedge-shaped friction block 3 and wedge-shaped friction block 4 to improve the wear resistance of wedge-shaped friction block 3 and wedge-shaped friction block 4.

[0041] In this embodiment, each of the opposite surfaces of the wedge-shaped friction block 3 and the wedge-shaped friction block 4 is provided with a corresponding protrusion 12, such as a T-shaped protrusion or a zigzag protrusion, in order to ensure the stability of the wedge-shaped friction block 3 and the wedge-shaped friction block 4 in the wedge groove 9 and avoid separation. The protrusion 12 is slidably installed in the corresponding limiting groove 10.

[0042] In this embodiment, a self-adjuster is fixedly installed at the top of the wedge-shaped friction block 3, and a cavity is opened inside the top of the wedge-shaped friction block 3.

[0043] In this embodiment, the self-adjuster includes an adjusting screw 31 and a compression spring 32. One end of the adjusting screw 31 is slidably installed in the cavity so that the adjusting screw 31 can move along the adjusting screw 31. The other end of the adjusting screw 31 is fixedly connected to the upper anti-detachment plate 6. The compression spring 32 is sleeved on the outside of the adjusting screw 31 and is located between the wedge-shaped friction block 3 and the upper anti-detachment plate 6 so that the wedge-shaped friction block 3 can have a certain movement buffer space during the braking process of contacting the T-rail 17.

[0044] In this embodiment, an anti-detachment block 8 is fixedly installed at the bottom of the second wedge friction block 4 to prevent the second wedge friction block 4 from being ejected from the top of the wedge groove 9.

[0045] In this embodiment, a slot 51 is provided through the surface of the reinforcing plate 5. The position of the slot 51 corresponds to the position of the wedge-shaped friction block 3 14. The length of the slot 51 is greater than the width of the wedge-shaped friction block 3 14 so that the wedge-shaped friction block 3 14 can extend out of the slot 51 during braking and have a certain upward movement space, thereby avoiding affecting the movement of the wedge-shaped friction block 1 3 and the wedge-shaped friction block 2 4.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
