Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a load-bearing beam assembly. Background Technology

[0002] As the market for self-built elevators continues to expand, the application of home elevators is becoming increasingly widespread. Home elevators typically have smaller top floors and pits, and most currently employ a beamless structure with the main unit resting on guide rails. However, some users, due to specific needs or performance requirements, may request a beam-supported structure during home elevator installation. While this structure provides stronger load-bearing capacity and ensures elevator stability, it also presents space challenges. Since the main unit needs to be fixed to the beam, it occupies a significant amount of top floor space, further confining what is already limited ceiling space. This is especially problematic in low-rise residences or in smaller spaces, where the main unit's large footprint results in the beam being installed too low, causing some elevator components to be higher than the beam, thus hindering proper installation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a load-bearing beam assembly that is not prone to interference with the top-level structure and can effectively avoid some of the load-bearing beams of the top-level structure.

[0004] To solve the above-mentioned technical problems, this utility model provides a load-bearing beam assembly, including a main load-bearing beam assembly, a secondary load-bearing beam assembly, a main unit, a steel strip rope head assembly, a connecting plate, a steel strip, and a rope head seat; the main load-bearing beam assembly and the secondary load-bearing beam assembly are connected through the connecting plate; the steel strip rope head assembly and the rope head seat are both disposed on the secondary load-bearing beam assembly, and the steel strip rope head assembly is connected to the rope head seat; the main load-bearing beam assembly includes a main load-bearing beam and a main load-bearing beam guide wheel, and the main unit and the main load-bearing beam guide wheel are both disposed on the main load-bearing beam; the secondary load-bearing beam assembly includes a secondary load-bearing beam, a first secondary load-bearing beam guide wheel, a second secondary load-bearing beam guide wheel, and a car guide wheel, and the first secondary load-bearing beam guide wheel and the second secondary load-bearing beam guide wheel are both disposed on the secondary load-bearing beam; the steel strip sequentially passes through the main unit, the main load-bearing beam guide wheel, the first secondary load-bearing beam guide wheel, the car guide wheel, the second secondary load-bearing beam guide wheel, and the steel strip rope head assembly.

[0005] As an improvement to the above scheme, the main load-bearing beam is installed at a lower height than the secondary load-bearing beam.

[0007] As an improvement to the above solution, the main load-bearing beam guide wheel is fixed to the main load-bearing beam by a main guide wheel clamping plate, the first secondary load-bearing beam guide wheel and the second secondary load-bearing beam guide wheel are respectively fixed to the secondary load-bearing beam by a main guide wheel clamping plate, and the car guide wheel guide wheel clamping plate is fixed to the top of the car.

[0008] As an improvement to the above solution, a host mounting base is also included, wherein the host is fixed to the main load-bearing beam via the host mounting base.

[0009] As an improvement to the above solution, the connecting plate is provided with an opening, one end of the steel strip is wrapped around the main unit, and the other end passes through the opening after passing around the main load-bearing beam guide wheel, and then passes around the first auxiliary load-bearing beam guide wheel.

The first side plate is connected to the first secondary load-bearing beam, and the third side plate is connected to the second secondary load-bearing beam.

[0012] As an improvement to the above solution, an elevator gantry frame located at the bottom of the secondary load-bearing beam is also included.

[0023] 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.

[0024] See Figure 1 , Figure 1 The specific structure of the load-bearing beam assembly of this utility model is shown, including a main load-bearing beam assembly 1, a secondary load-bearing beam assembly 2, a main unit 3, a steel strip rope head assembly 4, a connecting plate 5, a steel strip 6, and a rope head seat 7; the main load-bearing beam assembly 1 and the secondary load-bearing beam assembly 2 are connected by the connecting plate 5; the steel strip rope head assembly 4 and the rope head seat 7 are both provided on the secondary load-bearing beam assembly 2, and the steel strip rope head assembly 4 is connected to the rope head seat 7; the main load-bearing beam assembly 1 includes a main load-bearing beam 11 and a main load-bearing beam guide wheel 12, the main unit 3 and the main load-bearing beam guide wheel 12, and the main load-bearing beam guide wheel 12. The heavy beam guide wheels 12 are all located on the main load-bearing beam 11; the secondary load-bearing beam assembly 2 includes a secondary load-bearing beam 21, a first secondary load-bearing beam guide wheel 22, a second secondary load-bearing beam guide wheel 23 and a car guide wheel 24, with the first secondary load-bearing beam guide wheel 22 and the second secondary load-bearing beam guide wheel 23 both located on the secondary load-bearing beam 21; the steel belt 6 sequentially passes around the main unit 3, the main load-bearing beam guide wheel 12, the first secondary load-bearing beam guide wheel 22, the car guide wheel 24, the second secondary load-bearing beam guide wheel 23 and the steel belt rope head assembly 4.

[0025] It should be noted that by distinguishing between the main load-bearing beam assembly 1 and the secondary load-bearing beam assembly 2, the various components that were previously placed on the same load-bearing beam are divided into two parts. A certain height difference is set between the two parts, and they are connected by a connecting plate 5. This saves a significant amount of top-floor space without sacrificing elevator performance, avoiding situations where installation is impossible. Furthermore, the car guide wheel 24 is fixedly connected to the top of the elevator car. By sequentially winding the steel belt 6 around the main unit 3, the main load-bearing beam guide wheel 12, the first secondary load-bearing beam guide wheel 22, the car guide wheel 24, the second secondary load-bearing beam guide wheel 23, and the steel belt rope end assembly 4, and adjusting the length of the steel belt 6 suspended between the first and second secondary load-bearing beam guide wheels 22 and 23, the height of the car guide wheel 24 is adjusted, ultimately achieving the lifting and lowering control of the elevator car.

[0026] Specifically, the main load-bearing beam 11 is installed at a lower height than the secondary load-bearing beam 21 to avoid the structure of the top floor of the building, and the elevator gantry is installed at the bottom of the secondary load-bearing beam 21 to prevent the elevator structure from hitting the secondary load-bearing beam 21.

[0027] See Figure 2 The main load-bearing beam 11 includes a first main load-bearing beam 111 and a second main load-bearing beam 112 arranged in parallel with each other, which can effectively ensure the symmetry and balance of the main load-bearing beam 11.

[0028] See Figure 3 The secondary load-bearing beam 21 includes a first secondary load-bearing beam 211 and a second secondary load-bearing beam 212 arranged in parallel with each other to ensure the symmetry and balance of the secondary load-bearing beam 21.

[0029] See Figure 4 , Figure 5 and Figure 6 The main load-bearing beam guide wheel 12 is fixed to the main load-bearing beam 11 by the main guide wheel clamping plate 81. The first secondary load-bearing beam guide wheel 22 and the second secondary load-bearing beam guide wheel 23 are respectively fixed to the secondary load-bearing beam 21 by the secondary guide wheel clamping plate 82. The car guide wheel 24 is fixed to the top of the car by the car guide wheel clamping plate 83. By setting the main guide wheel clamping plate 81, the secondary guide wheel clamping plate 82, and the car guide wheel clamping plate 83, each guide wheel can be stably fixed to its corresponding component.

[0030] Specifically, the load-bearing beam assembly of this utility model also includes a main unit mounting base 9, and the main unit 3 is fixed to the main load-bearing beam 11 through the main unit mounting base 9.

[0031] See Figure 7The connecting plate 5 has an opening 51. One end of the steel belt 6 is wound around the main unit 3, and the other end passes through the opening 51 after passing around the main load-bearing beam guide wheel 12, and then passes around the first auxiliary load-bearing beam guide wheel 22. By setting this opening 51, the steel belt 6 can connect the main load-bearing beam guide wheel 12 and the first auxiliary load-bearing beam guide wheel 22 with the shortest possible length, and there is no need to add other guide wheels in the middle for steering.

[0032] like Figure 6 As shown, the secondary load-bearing beam assembly 2 also includes a first fixing plate 251 and a second fixing plate 252, both of which are fixedly connected to the first secondary load-bearing beam 211 and the second secondary load-bearing beam 212.

[0033] like Figure 3 As shown, the secondary load-bearing beam assembly 2 also includes a rope end plate 26, which includes a first side plate 261, a second side plate 262, and a third side plate 263. The first side plate 261, the second side plate 262, and the third side plate 263 are connected in sequence to form a "U"-shaped structure. The second side plate 262 is connected to the side walls of the first fixing plate 251 and the second fixing plate 252. The first side plate 261 is connected to the first secondary load-bearing beam 211, and the third side plate 263 is connected to the second secondary load-bearing beam 212. The rope end seat 7 is fixed to the secondary load-bearing beam assembly 2 through the rope end plate 26. By designing the rope end plate 26 as a "U"-shaped structure, with adjacent sides at 90°, the structure is more stable and less prone to deformation.

[0034] It should be noted that by setting the fixing plate at a position that can abut against the rope end plate 26, when the rope end plate 26 is subjected to a certain force, part of the force can be discharged to the first fixing plate 251 and the second fixing plate 252, so that the rope end plate 26 is not easily deformed or tilted, thus enhancing the strength of the rope end plate 26.

[0035] See Figure 8 It also includes an elevator gantry 10 located at the bottom of the secondary load-bearing beam 21, which provides support and guidance for the elevator car, making the elevator operation more stable and safe.

[0036] As can be seen from the above, this utility model, by introducing the main load-bearing beam assembly 1 and the secondary load-bearing beam assembly 2, achieves the separation of various components, which were previously placed on the same load-bearing beam, into two parts of different heights without sacrificing elevator performance. This saves a significant amount of top-floor space and avoids the impact of the original top-floor structure of the building on the normal installation of the elevator. By setting the connecting plate 5, the main load-bearing beam assembly 1 and the secondary load-bearing beam assembly 2 are stably connected together. By the main unit 3 stretching the steel belt 6, and with the cooperation of the steel belt rope head assembly 4 and the guide wheel, the length of the steel belt 6 is controlled to adjust the height of the car guide wheel 24, ultimately achieving the lifting and lowering control of the elevator car. This utility model also provides a main guide wheel clamping plate 81, a secondary guide wheel clamping plate 82, and a car guide wheel clamping plate 83 to ensure that the main load-bearing beam guide wheel 12, the first secondary load-bearing beam guide wheel 22, the second secondary load-bearing beam guide wheel 23, and the car guide wheel 24 are stably connected to the main load-bearing beam 11, the secondary load-bearing beam 21, and the car, respectively. The secondary load-bearing beam assembly 2 also includes a first fixing plate 251, a second fixing plate 252, and a rope end plate 26. The first fixing plate 251 and the second fixing plate 252 are used to achieve a fixed connection between the first secondary load-bearing beam 211 and the second secondary load-bearing beam 212, and abut against the rope end plate 26. The rope end plate 26 is used to connect the rope end seat 7, so that the rope end seat 7 can be stably fixed on the secondary load-bearing beam assembly 2.

[0037] 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 invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
