Technical Field

[0001] This invention relates to the field of residential elevator devices, and in particular to a lifting elevator for low-rise residential buildings. Background Technology

[0002] With the continuous advancement of urban-rural integration in my country, people's lifestyles have undergone fundamental changes, further promoting the continuous increase in the number of floors in residential buildings and leading to an increase in the use of elevators in new urban communities. As one of the important means of transportation for people, elevators bring convenience, but the incidence of elevator safety accidents is also increasing. Therefore, how to ensure elevator safety and make it more effective in serving everyone has become an increasingly important issue of common concern.

[0003] In recent years, elevators have been gradually installed in low-rise residential buildings. Low-rise elevators have low operating speeds, and when malfunctions occur, they are often stopped by friction locking. The stopping position is difficult to determine, and the friction buffer wear is relatively large, making maintenance troublesome. Summary of the Invention

A vertical groove is formed on one side of the auxiliary safety rail, and an embedded slide rail is embedded in the inner wall of the vertical groove. The inner rail slide bar is slidably installed within the embedded slide rail. The deceleration mechanism is fixedly installed on the side of the car. A deceleration drive groove is formed on one side of the deceleration mechanism. A micro motor is fixedly installed on the inner wall of the deceleration drive groove.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1-7 The elevator shown is a type of elevator for low-rise residential buildings, which consists of a car 1, auxiliary safety rails 2, and deceleration rails 3.

[0025] The front and rear sides of the deceleration groove 3 are equipped with inner rail slide bars 21. A vertical groove is opened on one side of the auxiliary safety groove bar 2. An embedded slide rail 33 is embedded in the inner side wall of the vertical groove. The inner rail slide bar 21 is slidably installed in the embedded slide rail 33. There are multiple deceleration grooves 3, which are fixedly installed on the side of the car 1 and distributed at the upper and lower ends of the side.

[0026] A deceleration drive groove 22 is provided on one side of the deceleration groove 3. A micro motor 25 is fixedly installed on the inner wall of the deceleration drive groove 22. A drive screw 26 is connected to the micro motor 25. A push frame 28 is screwed onto the drive screw 26. The push frame 28 can move horizontally under the rotation of the drive screw 26. A deceleration back pressure column 31 is slidably inserted on the push frame 28. A spring pressure block 18 is fixedly installed at one end of the deceleration back pressure column 31. A spring retaining ring 27 is fixedly installed at the other end of the deceleration back pressure column 31, which mainly serves as a limit. A deceleration buffer spring 30 is sleeved on the deceleration back pressure column 31 between the spring pressure block 18 and the push frame 28.

[0027] The outer side of the spring-loaded block 18 is set as an inclined surface 24. A stop block 20 is integrally connected to the bottom of the inclined surface 24. A deceleration pressure wheel 19 is rotatably installed on the inclined surface 24. After being compressed, the spring-loaded block 18 presses the deceleration buffer spring 30 to compress the force.

[0028] A deceleration strip assembly 32 is also fixedly installed on the inner wall of the vertical groove. The deceleration strip assembly 32 consists of several deceleration inclined surfaces 34. The outer side of the inclined surface 34 is a pressing inclined surface. A blocking groove 35 is opened on the pressing inclined surface of the inclined surface 34. The blocking block 20 extends into the blocking groove 35 and stops when it slides to the bottom of the blocking groove 35. The deceleration pressure roller 19 presses onto the inclined surface 34. In this embodiment, in conjunction with a speed sensor, when the speed exceeds the limit, the micro motor 25 starts to drive the push frame 28 to move, push the blocking block 20 into the blocking groove 35, and the deceleration pressure roller 19 presses onto the deceleration inclined surface 34 to decelerate and stop.

[0029] An upper mounting frame 4 is fixedly installed at the bottom of the car 1. A lower mounting frame 5 is connected to the bottom of the upper mounting frame 4 via a frame clamping spring 7. Several limiting posts 10 are inserted on the lower mounting frame 5. A column top hinge 9 is fixedly installed on the top of the limiting posts 10. Two support rods 12 are rotatably installed on the column top hinge 9. An end hinge 8 is rotatably installed at the end of the support rods 12. A frame bottom slide groove 16 is opened at the bottom of the upper mounting frame 4. The number of frame bottom slide grooves 16 is the same as the number of limiting posts 10. A frame bottom slide column 15 is fixedly installed in the frame bottom slide groove 16. Two frame bottom sliders 13 are slidably installed on the frame bottom slide column 15. The two frame bottom sliders 13 move in opposite directions. The bottom of the frame bottom sliders 13 is fixedly installed together with the end hinge 8. A frame bottom horizontal spring 17 is sleeved on the frame bottom slide column 15 between the frame bottom sliders 13 and the inner wall of the frame bottom slide groove 16.

[0030] The upper mounting frame 4 and the lower mounting frame 5 serve as the last buffer protection for the car 1. They provide buffering when the car lands, and the double buffering is achieved through the support rod 12 that unfolds under pressure and the frame clamping spring 7.

[0031] The deceleration ramp 34 corresponds to the number of floors. This embodiment is mainly for installation in buildings with six floors or less. Taking a six-story building as an example, the deceleration ramp 34 has six floors, and each floor's exit is positioned at a lower location. In this way, when the buffer stops, it can stop the car 1 at the exit.

[0032] In this embodiment, a limiting bottom ring 11 is fixedly installed at the bottom of the limiting post 10, and auxiliary sliders 6 are installed at both ends of the lower mounting frame 5. The auxiliary sliders 6 extend into the vertical groove to facilitate limiting the lower mounting frame 5.

[0033] In this embodiment, spring mounting plates 14 are fixedly installed at both ends of the spring 7. The upper mounting frame 4 and the lower mounting frame 5 are both provided with mounting plate grooves. The spring mounting plates 14 are fixedly installed into the mounting plate grooves by screws, which facilitates replacement and maintenance.

[0034] In this embodiment, a number of limiting horizontal columns 29 are slidably inserted on the push frame 28. One end of the limiting horizontal column 29 is fixedly installed on the inner wall of the deceleration drive groove 22, and it is mainly used to limit the push frame 28.

[0035] In this embodiment, a number of assisting balls 23 are installed on the upper and lower walls of the deceleration drive groove 22. When the spring-loaded block 18 is pressed, it moves with the assistance of the assisting balls 23.

[0036] The above structure is assisted by an overspeed detection mechanism. When the elevator overspeeds, the micro motor 25 starts and drives the drive cylinder 27 to rotate, which causes the push frame 28 to push the spring block 18 out. The deceleration pressure roller 19 presses onto the deceleration inclined surface 34. When it rolls on the deceleration inclined surface 34, it is decelerated and buffered by the deceleration buffer spring 30 until the stop block 20 reaches the bottom of the stop slide 35 and stops. At this time, the car door of the car 1 is aligned with the exit, which facilitates rescue and exit.

[0037] The upper mounting bracket 4 and lower mounting bracket 5 at the bottom serve as a landing protection device. They provide double cushioning through the frame clamp springs and the horizontal spring 17 at the bottom of the frame, which is linked to the support rod 12. The cushioning effect is good.

[0038] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
