Description

Elevator frame and elevator

Technical Field

The utility model belongs to the technical field related to elevators, and in particular relates to an elevator car frame and an elevator.

Background Art

In the elevator field, when the elevator car is very deep or has a heavy load, an elevator car frame with sufficient strength is required to support the entire elevator car to run vertically in the hoistway, and a multi-track elevator car layout is usually adopted.

In order to ensure the structural strength of the elevator car frame, in addition to increasing the size of the elevator car frame structure, another way is to add diagonal tie rods to the elevator car frame. At present, the arrangement structure of the diagonal tie rods in the existing elevator car frame has limited force reinforcement on the elevator car frame, and the diagonal tie rods may need to pass through the secondary straight beam on the elevator car frame, thereby affecting the structural strength of the secondary straight beam itself, which will reduce the overall structural strength of the elevator car frame.

As shown in Fig. 1 and Fig. 3, in some embodiments, a tie rod hanging ear 230 is connected to the bottom bracket beam 23, and the bottom bracket beam 23 is connected to the diagonal tie rod 24 through the tie rod hanging ear 230. It should be noted that the tie rod hanging ear 230 and the diagonal tie rod 24 can be connected by a screw rod. Of course, for those skilled in the art, the diagonal tie rod 24 can also be fixed to the bottom bracket beam 23 by a connector such as a latch, which will not be elaborated here.

As shown in Fig. 1 and Fig. 3, in some embodiments, the car bottom bracket beam 23 includes a first car bottom bracket beam 231, which is arranged on the side of the auxiliary lower beam 222 away from the main lower beam 212; accordingly, the inclined rod 24 includes a first inclined rod 241, one end of which is connected to the first car bottom bracket beam 231, and the other end of which is arranged between the main straight beam 213 and the auxiliary straight beam 223 and connected to the car frame cross bar 25. That is to say, the elevator car frame 100 of this embodiment can realize the support of the part of the car bottom 10 extending out of the auxiliary lower beam 222 by the cooperation between the first car bottom bracket beam 231 and the first inclined rod 241, so that the bearing capacity of the car bottom 10 in the elevator car frame 100 can be further improved.

As shown in Fig. 1 and Fig. 3, in some embodiments, the car bottom bracket beam 23 further includes a second car bottom bracket beam 232, which is disposed between the auxiliary lower beam 222 and the main lower beam 212; correspondingly, the inclined rod 24 further includes a second inclined rod 242, one end of which is connected to the second car bottom bracket beam 232, and the other end of which is disposed between the main straight beam 213 and the auxiliary straight beam 223 and connected to the car frame cross bar 25. In this way, the structural strength of the elevator car frame 100 can be further improved.

In this embodiment, the number of the second car bottom bracket beam 232 is one, and the number of the second inclined rods 242 is two; the two second inclined rods 242 are symmetrically arranged on both sides of the second car bottom bracket beam 232. That is, the elevator car frame 100 of this embodiment can use two second inclined rods 242 to simultaneously carry the second car bottom bracket beam 232, so that the structural strength of the elevator car frame 100 can be further improved.

As shown in Figures 1, 3 and 4, in this embodiment, along the length direction of the auxiliary upper beam 221, the auxiliary straight beam 223 is arranged on the side of the main straight beam 213 away from the car bottom 10; the length of the auxiliary upper beam 221 is greater than the length of the main upper beam 211, and the length of the auxiliary lower beam 222 is correspondingly greater than the length of the main lower beam 212; a headrest 2231 is connected to the auxiliary straight beam 223, and the headrest 2231 can be fixed to the auxiliary straight beam 223 by welding, and the car frame cross bar 25 is connected to the auxiliary straight beam 223 through the headrest 2231; wherein, a preset space is formed between the auxiliary straight beam 223 and the car frame cross bar 25 along the length direction of the auxiliary upper beam 221, for accommodating a portion of the diagonal rod 24 passing along the inner side of the auxiliary straight beam 223. That is to say, the car frame cross bar 25 is separated from the auxiliary straight beam 223 by the cushioning member 2231, so as to make up for the distance of the auxiliary straight beam 223 from the main straight beam 213 in the length direction of the auxiliary upper beam 221 away from the car bottom 10. In this way, on the basis of ensuring the connection between the car frame cross bar 25 and the main straight beam 213 and the auxiliary straight beam 223, the auxiliary straight beam 223 can be arranged away from the first inclined rod 241. In this way, on the basis of satisfying the staggered arrangement of the first inclined rod 241 and the auxiliary straight beam 223, the structure of the elevator car frame 100 is simplified, and the arrangement of the first inclined rod 241 in the elevator car frame 100 is facilitated.

It should be noted that, in the elevator car frame 100, since the auxiliary straight beam 223 is arranged perpendicular to the auxiliary lower beam 222 and the auxiliary upper beam 221, in order to achieve the purpose of arranging the auxiliary straight beam 223 along the length direction of the auxiliary upper beam 221 on the side of the main straight beam 213 away from the car bottom 10, it can be achieved by extending the auxiliary lower beam 222 and the auxiliary upper beam 221 outward relative to the main lower beam 212 and the main upper beam 211, which will not be elaborated here.

Furthermore, along the length direction of the auxiliary upper beam 221, a preset gap is formed between the first oblique rod 241 and the auxiliary straight beam 223, so that the arrangement of the first oblique rod 241 is not constrained by the auxiliary straight beam 223. In this way, the arrangement of the first oblique rod 241 can be facilitated, and the first oblique rod 241 can be improved according to different needs, for example, using sound insulation materials for shock absorption and anti-collision treatment, or setting the cross-section of the first oblique rod 241 to a different shape, or setting the first oblique rod 241 to be thickened, which will not be elaborated here.

In this embodiment, the number of the first car bottom bracket beam 231 is one, and the number of the first inclined rods 241 is two; the two first inclined rods 241 are symmetrically arranged on both sides of the first car bottom bracket beam 231. And the two first inclined rods 241 are connected to two corresponding car frame cross bars 25, that is, the elevator car frame 100 of this embodiment can use two first inclined rods 241 to simultaneously support the two ends of the first car bottom bracket beam 231, so that the structural strength of the elevator car frame 100 can be further improved.

In one embodiment, the number of the first car bottom bracket beam 231 is one, and the number of the first diagonal rods 241 is at least two; one end of each of the at least two first diagonal rods 241 is connected to the same car frame cross bar 25, and the other end of each is connected to the same side of the first car bottom bracket beam 231.

A plurality of first inclined rods 241 and second inclined rods 242 can be arranged on the same side of the car frame cross bar 25 according to actual use.

In addition, the present application also provides an elevator, comprising the elevator car frame 100 described above.

In summary, the elevator car frame 100 of the present application uses a main car frame 21 and two auxiliary car frames 22 to support the car bottom 10, and then uses a diagonal tie rod 24 to support the car bottom support beam 23 and the car frame cross bar 25. Since the setting of the diagonal tie rod 24 will not destroy the structure of the auxiliary straight beam 223 on the auxiliary car frame 22, and the auxiliary straight beam 223 and the main straight beam 213 on the main car frame 21 can jointly support the diagonal tie rod 24 through the car frame cross bar 25, this can further ensure the overall structural strength of the elevator car frame 100, so that the elevator car frame 100 has high reliability and can adapt to the needs of various elevator car layouts.

The technical features of the above embodiments may be arbitrarily combined.
