Description

Technical Field

[0002] At present, in the existing field of elevator technology, the traction machine is the core component of the elevator system. Its stability and reliability are directly related to the overall safety and operating efficiency of the elevator. The design of the traction machine base structure plays a vital role in the fixation of the stator part. However, the traditional traction machine base structure has some shortcomings in this regard.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN218465282U, which discloses a base structure for an elevator traction machine.

However, the electronic fixing seat of this patent is suspended in the hollow base plate and then fixed by bolts. While this arrangement reduces the difficulty of transportation and installation, it creates a safety hazard and does not provide sufficient support for the stator, resulting in more severe vibration.

[0053] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0054] Example 1

[0055] like Figure 1-4 As shown, an elevator traction machine base structure,

[0056] The elevator traction machine 5 includes a driving portion 51, an output shaft 52, and a traction sheave 53. The driving portion 51 is adapted to drive the output shaft 52 to rotate, thereby driving the traction sheave 53 to rotate. The specific structure of the elevator traction machine 5 is conventional and will not be described in detail in this embodiment.

[0057] The elevator traction machine base structure includes:

[0058] The base body 1 includes a base 11, support legs 12, and an arc-shaped bottom plate 13. The support legs 12 are connected to the top of the base 11, and the arc-shaped bottom plate 13 is connected to the top of the support legs 12.

[0059] The stator fixing frame 2 is placed on the arc-shaped bottom plate 13, the driving part 51 is installed in the stator fixing frame 2, and the output shaft 52 extends to the outside of the stator fixing frame 2;

[0060] Limiting component 1 3, limiting component 1 3 includes two connecting plates 31, the two connecting plates 31 are respectively connected to the two sides of the arc-shaped bottom plate 13, the two sides of the stator fixing frame 2 are in contact with the inner sides of the corresponding two connecting plates 31, and the stator fixing frame 2 and the connecting plates 31 are both provided with connecting holes 32, and a fixing component is passed through the connecting hole 32 to connect the connecting plates 31 and the stator fixing frame 2.

[0061] like Figure 2 、 Figure 4-7 As shown, the substrate structure further includes a second limiting component 4, and the second limiting component 4 includes an inner tooth 42 and an outer tooth 43;

[0062] The inner teeth 42 are located inside the arc-shaped bottom plate 13, and the outer teeth 43 are located on the outer peripheral surface of the stator fixing frame 2;

[0063] After the stator fixing frame 2 is placed on the arc-shaped bottom plate 13 , the inner teeth 42 and the outer teeth 43 are engaged with each other.

[0064] like Figure 5 As shown, the second limiting component 4 further includes a cover plate 41. A through slot is formed on the arc-shaped bottom plate 13, and the cover plate 41 is detachably connected to the outer peripheral surface of the arc-shaped bottom plate 13. The cover plate 41 is suitable for covering the through slot.

[0065] The inner teeth 42 are connected to one side of the contact surface between the cover plate 41 and the arc-shaped bottom plate 13 , and pass through the interior of the through slot.

[0066] like Figure 2 、 Figure 5 As shown, a shaft protection assembly 6 is connected to one side of one of the stator fixing frames 2 , and the output shaft 52 passes through the shaft protection assembly 6 .

[0067] like Figure 5 As shown, the shaft protection component 6 is a protective sleeve 61.

[0068] like Figure 2 、 Figure 5 、 Figure 8 As shown, a support assembly is provided at the bottom of the protective cover 61, and a shrinking assembly is provided on the base 11;

[0069] The support assembly is adapted to support the protective cover 61 and move in response to the vibration of the protective cover 61;

[0070] The retraction assembly is adapted to restore the support assembly after the support assembly has moved.

[0071] like Figure 5 As shown, the support assembly includes a support block 62 connected to the bottom of the protective cover 61;

[0072] A hinge rod 63 is movably hinged in the support block 62 .

[0073] like Figure 8 As shown, the retraction assembly includes a slider 64, a telescopic rod 65 and a spring 66;

[0074] A slide groove is provided on the base 11, and the slider 64 is slidably connected inside the slide groove;

[0075] The telescopic rod 65 is connected between the inner wall of the chute and the slider 64;

[0076] The spring 66 is sleeved on the outside of the telescopic rod 65 , and the two ends of the spring 66 are respectively connected to the inner wall of the slide groove and one end of the slider 64 .

[0077] The working principle of this embodiment is as follows:

[0078] During the installation process, first fix the two supporting legs 12 on the base 11, and then fix the arc-shaped bottom plate 13 on the two supporting legs 12 to form the bottom support of the stator fixing frame 2;

[0079] Then, place the stator fixing frame 2 with the driving part 51 installed inside on the curved bottom plate 13, and then install the connecting plates 31 on both sides of the curved bottom plate 13. The connecting plates 31 fix the curved bottom plate 13 and the stator fixing frame 2. This part is the first fixation of the stator fixing frame 2.

[0080] After the first fixation, the two cover plates 41 are fixed on the arc-shaped bottom plate 13 to cover the two through slots on the arc-shaped bottom plate 13. At the same time, the inner teeth 42 provided on the cover plates 41 engage with the outer teeth 43 on the stator fixing frame 2 to achieve the second fixation of the stator fixing frame 2.

[0081] The stability of the stator fixing frame 2 is improved by fixing twice;

[0082] After the stator fixing frame 2 is fixed, the output shaft 52 connected to the driving part 51 in the stator fixing frame 2 extends to the outside of one of the connecting plates 31. A protective cover 61 is connected to one side of the connecting plate 31. The output shaft 52 is located inside the protective cover 61. The protective cover 61 protects and supports the output shaft 52.

[0083] Since the traction wheel 53 will vibrate during operation, when the vibration is too large, it will directly affect the output shaft 52, causing the output shaft 52 to vibrate or even produce obvious deflection. At this time, both the vibration and the deflection will directly act on the protective cover 61 outside the output shaft 52. When the protective cover 61 vibrates or deflects, it will drive the support block 62 and the hinged rod 63 movably hinged in the support block 62 to deflect, thereby driving the slider 64 at the other end of the hinged rod 63 to move in the slide groove on the base 11. During the movement of the slider 64, the telescopic rod 65 and the spring 66 are squeezed. At this time, the spring 66 will generate a reaction force to buffer and offset the deflection of the slider 64, thereby supporting the slider 64. The supporting force is transmitted to the hinged rod 63 and the support block 62 through the slider 64, and finally acts on the protective cover 61, so that the amplitude of the vibration and deflection of the protective cover 61 is reduced, thereby achieving the effect of reducing the vibration of the output shaft 52.

[0084] Example 2

[0085] like Figure 1 、 Figure 2 As shown, this embodiment further includes the following structures on the basis of the first embodiment: an adjustment component 7 and a shell 71 are provided on the protective cover 61, and the shell 71 is suitable for sliding on the outer peripheral surface of the protective cover 61 through the adjustment component 7;

[0086] The housing 71 is semicircular and hollow, and covers the outside of the traction sheave 53;

[0087] Limiting plates 72 are provided on both sides of the housing 71 , and limiting grooves are formed in the limiting plates 72 and pass through the limiting plates 72 .

[0088] like Figure 9 As shown, the adjustment assembly 7 includes a slide rail 73 and an adjustment plate 74 connected to the outer peripheral surface of the protective cover 61;

[0089] The adjustment plate 74 is slidably connected to the interior of the slide rail 73, and one end of the adjustment plate 74 is connected to the housing 71;

[0090] A locking component 75 is provided between the adjustment plate 74 and the slide rail 73 .

[0091] The working principle of this embodiment is as follows:

[0092] An adjustable housing 71 is provided on the outer circumference of the protective cover 61. The housing 71 covers the outside of the traction sheave 53. A limit plate 72 on the housing 71 is used to limit the position of the rope to prevent the rope from deflecting under the drive of the traction sheave 53, thereby affecting the normal movement of the elevator car.

[0093] It should be noted that one end of the shell 71 is connected to the adjustment plate 74, and the adjustment plate 74 moves in the slide rail 73 fixed on the outer surface of the protective cover 61. The position of the shell 71 and the limit plate 72 thereon is realized by changing the position of the adjustment plate 74. The position of the limit plate 72 can be adjusted according to actual use conditions, thereby controlling the position of the rope on the traction wheel 53. After the adjustment plate 74 is adjusted, it is necessary to fix the adjustment plate 74 and the slide rail 73. A U-shaped groove is provided on the slide rail 73, and a plurality of threaded holes are provided on the adjustment plate 74. The slide rail 73 and the adjustment plate 74 can be fixed by the cooperation of bolts and nuts.
