The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Examples

The utility model discloses a heavily press decline buffering elevator, refer to figure 1 ~ 4 and show, including setting up car 20 in elevartor shaft 10. The bottom of the car 20 is provided with a slide bar 32, a slide block 40 and a buffer bar. The slide bar 32 is fitted at its side with a wedge 34. Slide 40 is located on the side of slide bar 32 adjacent to wedge 34. The slide block 40 slides in a direction perpendicular to the slide bar 32. Two buffer rods are coaxially hinged at the bottom of the car 20. One end of each of the two buffer rods is respectively positioned at two sides of the sliding block 40, and the other end of each of the two buffer rods is provided with a buffer wheel 56. A buffer block 60 is provided on the inner wall of the elevator shaft 10. The buffer block 60 is gradually widened from top to bottom. Two buffer wheels 56 are respectively located on both sides of the buffer block 60. With the above optimized design, after the car 20 of the elevator reaches the corresponding floor, the sliding rod 32 is moved to push the wedge 34 against the sliding block 40; the slide 40 is inserted between two buffer rods which are far from each other at the end and close to each other at the other end, so that the buffer wheel 56 is clamped on the buffer block 60; in the elastic range of the buffer rod, the lower the height of the car 20 is, the tighter the buffer wheel 56 is clamped, the better the buffer effect is, in the bearing range of the elevator, the over-descending of the elevator can be well avoided, the load of a sling and a driving source is reduced, and the service life of the elevator is prolonged; meanwhile, the buffer wheel 56 and the buffer block 60 are used, so that hard contact can be avoided, and the service life is long.

The buffer block 60 includes at least two widened amplitudes. The widening amplitude above is smaller than the widening amplitude below. The small widening width above can be suitable for small loads; when the load exceeds a certain level, the buffer strength can be increased by a large downward widening width. And the service life of parts can be further prolonged by the aid of hierarchical buffering.

The buffer block 60 includes a first buffer portion 61 and a second buffer portion 62. The included angle between two side surfaces of the first buffer part 61 is 20-45 degrees. The second buffer portion 62 is continuously provided at the end of the first buffer portion 61. The included angle between the two side surfaces of the second buffer part 62 is 90-135 degrees.

The buffer rods include a rotary table 52, a first front buffer rod 53, a second front buffer rod 54 and a rear buffer rod 55. The turntables 52 of the two buffer rods are coaxially hinged at the bottom of the car 20. The first front buffer rods 53 are arranged on one side of the rotary discs 52, and the first front buffer rods 53 on the two rotary discs 52 are gradually far away. The second front buffer rods 54 are arranged at the tail ends of the first front buffer rods 53, and the second front buffer rods 54 on the first two front buffer rods 53 are gradually close to each other. The rear buffer rods 55 are disposed at the other side of the rotary table 52, and the rear buffer rods 55 on the two rotary tables 52 are gradually distant. A buffer wheel 56 is provided at the end of the rear buffer rod 55. When the sliding rod 32 is moved, the sliding block 40 is inserted between the two second front buffer rods 54, and the second front buffer rods 54 are clamped on the sliding block 40, so that the reliability is improved; meanwhile, when the sliding block 40 is moved out, the two buffer wheels 56 are separated by the buffer block 60 under the residual of the weight of the car 20, so that the car 20 can normally fall.

An elastic member 57 is disposed outside the second front bumper 54. The elastic part 57 can make the two front buffer rods 54 have the tendency of approaching each other, so that the rebounding speed is increased, and the running stability of the elevator is ensured.

The slider 40 is provided with a triangular head 41. The tip part of the triangular head 41 is positioned between the two front buffer rods 54. The triangular head 41 can make the sliding block 40 be more easily inserted between the two second front buffer rods 54, and when sliding out, the distance between the two second front buffer rods 54 can be reduced as much as possible, thereby saving space.

The slider 40 has a guide surface 42 formed on an end portion thereof facing the triangular head 41. Guide surface 42 is located on the forward side of wedge 34. The guide surface 42 enables the wedge 34 to be better pushed against the rear end of the slide 40.

The wedge surface of the wedge 34 is provided with a holding surface 35 parallel to the moving direction thereof. The holding surface 35 is pushed against the rear end of the slider 40. The holding surface 35 can convert the force given by the car 20 into a force acting on the component itself, reducing the system load on the movable member.

The car 20 has a bottom provided with a mounting plate 50 and a rotating shaft 51. The mounting plate 50 is wrapped around the bottom of the bumper beam. The shaft 51 is located within the mounting plate 50. The buffer rod is hinged to the car 20 by a rotating shaft 51. The mounting plate 50 can offset the vertical force applied to the buffer rod, thereby reducing the burden on the rotation shaft 51.

A connecting plate 30 is provided at the bottom of the car door 21 of the car 20. The connecting plate 30 is hinged with a connecting rod 31. The other end of the link 31 is hinged to the end of the slide lever 32. The bottom of the car 20 is provided with a chute 33. The slide rod 32 is slidably disposed in the slide groove 33. When the car door 21 is opened, the slide rod 32 can be pulled to enable the elevator to have a buffer function; when the car door 21 is closed, the slide lever 32 can be pushed to unlock the elevator.
