Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a machine room-less elevator and its load-bearing beam structure. Background Art

[0002] As residents' living standards continue to improve, there is a growing demand for elevators to be installed in stairwells. However, some low-rise buildings lack elevator shafts and can only install machine-room-less elevators. Machine-room-less elevators have limited shaft area and limited space on the top floor. Therefore, the load-bearing beams of machine-room-less elevators cannot be fitted into the walls, and openings in the walls are not permitted, significantly increasing the installation difficulty and manufacturing cost of machine-room-less elevators. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a machine room-less elevator and its load-bearing beam structure, which has a simple structure, is safe and easy to construct, and can meet the load-bearing requirements of the load-bearing beam.

[0004] To solve the above problems, this utility model proposes a load-bearing structure for a machine room-less elevator, including load-bearing brackets at both ends of the load-bearing beam, wherein the load-bearing brackets are fixedly connected to the wall of the shaft.

[0005] The load-bearing support includes a main body and a supporting part. The supporting part is provided on the main body. The main body is provided with a plurality of reinforcing ribs arranged at predetermined intervals below the supporting part. The reinforcing ribs are fixedly connected to the main body and the supporting part respectively. The main body is fixedly connected to the wall of the shaft, and the supporting part is fixedly connected to the load-bearing beam.

[0006] As an improvement to the above technical solution, the surface of the supporting part is provided with an installation guide groove, and the load-bearing beam is provided on the installation guide groove.

[0007] As an improvement to the above technical solution, the main body is provided with a plurality of heavy-duty anchor bolts, and the main body is fixedly connected to the wall of the well shaft through the heavy-duty anchor bolts.

[0008] As an improvement to the above technical solution, the load-bearing support is a one-piece molded structure.

[0009] As an improvement to the above technical solution, a hydraulic shock absorber is provided between the bottom of the load-bearing beam and the supporting part.

[0010] As an improvement to the above technical solution, the hydraulic shock absorber includes a first hydraulic cylinder, a second hydraulic cylinder, and a hydraulic column;

[0011] The first hydraulic cylinder is sleeved outside the second hydraulic cylinder, and the second hydraulic cylinder is sleeved outside the hydraulic column. The hydraulic column can move up and down along the second hydraulic cylinder and is fixedly connected to the bottom of the load-bearing beam. The bottom of the second hydraulic cylinder is provided with an oil drain hole, and the side wall is provided with an oil return hole.

[0012] As an improvement to the above technical solution, the relative positions of the first hydraulic cylinder and the second hydraulic cylinder are fixed, and a through cavity is formed through the oil drain hole and the oil return hole.

[0013] Accordingly, this utility model also provides a machine room-less elevator, including the load-bearing beam structure described above.

[0014] The following are the beneficial effects of implementing this utility model:

[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0020] See Figure 1 and Figure 2 As shown, this utility model embodiment provides a load-bearing structure for a machine room-less elevator, including load-bearing brackets 2 at both ends of the load-bearing beam 1, wherein the load-bearing brackets 2 are fixedly connected to the wall of the shaft.

[0021] This invention improves the method of fixing load-bearing beams to walls, thereby reducing the difficulty and cost of installing load-bearing beams.

[0022] Specifically, the load-bearing support 2 includes a main body 21 and a supporting part 22. The supporting part 22 is provided on the main body 21. The main body 21 has a plurality of reinforcing ribs 23 arranged at predetermined intervals below the supporting part 22. The reinforcing ribs 23 are fixedly connected to the main body 21 and the supporting part 22 respectively. The main body 21 is fixedly connected to the wall of the shaft, and the supporting part 22 is fixedly connected to the load-bearing beam 1.

[0023] The main body of the load-bearing bracket 2 is fixedly connected to the wall, and the supporting part is used to support the load-bearing beam 1. The above structure does not require pre-drilled holes in the shaft wall, which reduces the installation difficulty and cost of the load-bearing beam while ensuring the load-bearing strength.

[0024] Preferably, the surface of the supporting part 22 is provided with an installation guide groove, and the load-bearing beam 1 is mounted on the installation guide groove. The installation guide groove plays a guiding and fixing role in the installation of the load-bearing beam 1, avoiding the problem of large offset distance of the load-bearing beam 1 during installation.

[0025] Preferably, the main body 21 is provided with a plurality of heavy-duty anchor bolts 3, and the main body 21 is fixedly connected to the wall of the well shaft through the heavy-duty anchor bolts 3.

[0026] Preferably, the load-bearing support 2 is a one-piece molded structure. This one-piece molded structure effectively improves the structural strength of the support and avoids the problem of easy breakage after prolonged use.

[0027] Preferred, see Figure 3 As shown, a hydraulic damping component 4 is provided between the bottom of the load-bearing beam 1 and the supporting part 22. Since the connection between the load-bearing beam 1 and the supporting part 22 is rigid, this structure provides a highly effective sound transmission medium for elevator vibration noise. To reduce the noise generated by the elevator during operation, a hydraulic damping component is installed between the load-bearing beam and the supporting part to reduce the vibration frequency of the load-bearing beam during operation.

[0028] Preferably, the hydraulic shock absorber 4 includes a first hydraulic cylinder 41, a second hydraulic cylinder 42, and a hydraulic cylinder 43;

[0029] The first hydraulic cylinder 41 is sleeved on the outside of the second hydraulic cylinder 42, and the second hydraulic cylinder 42 is sleeved on the outside of the hydraulic column 43. The hydraulic column 43 can move up and down along the second hydraulic cylinder 42 and is fixedly connected to the bottom of the load-bearing beam 1. The bottom of the second hydraulic cylinder 42 is provided with an oil drain hole 45 and the side wall is provided with an oil return hole 44.

[0030] Preferably, the relative positions of the first hydraulic cylinder 41 and the second hydraulic cylinder 42 are fixed, forming a through cavity through the drain hole 45 and the return hole 44. When the load-bearing beam 1 vibrates, the hydraulic cylinder 43 moves up and down with the load-bearing beam 1, while the hydraulic oil flows back and forth between the first hydraulic cylinder 41 and the second hydraulic cylinder 42 through the drain hole 45 and the return hole 44.

[0031] Accordingly, this utility model embodiment also provides a machine room-less elevator, including the load-bearing beam structure described above.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
