Description

Technical Field

[0001] The utility model relates to the technical field of elevator measurement, in particular to an elevator balance measurement auxiliary device. Background Art

[0002] As an important parameter for elevator use, the elevator balance coefficient directly affects the safety and comfort performance of traction-driven elevators. After the elevator is installed, balance measurement is required, mainly to ensure that the elevator can remain stable and safe during operation. Balance measurement can check whether the elevator's suspension system and counterweight system are operating normally, and ensure that the elevator can operate in a balanced manner under different load conditions. Through balance measurement, potential problems can be discovered and solved to ensure the safety and reliability of the elevator. Therefore, balance measurement is an important link to ensure the normal operation of the elevator, and it is also a guarantee of elevator safety and performance. When performing elevator balance measurement, it is generally necessary to adjust the mass difference between the elevator car and the counterweight to achieve a balanced state. Usually, the measurement personnel will adjust by moving the weights at the bottom of the elevator shaft to achieve an ideal balance state. This process requires the measurement personnel to move the weights to adjust the mass difference between the elevator car and the counterweight, which requires a large labor intensity for the measurement personnel, so an elevator balance measurement auxiliary device is proposed.

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] Reference Figures 1 to 4 The embodiment of the utility model provides an elevator balance measurement auxiliary device, including a temporary storage rack 10, a weight 20, a lifting mechanism 30 and a suspension mechanism 40.

[0030] The temporary storage rack 10 includes a base 11 and a vertical plate 12 arranged on the four sides of the base 11, and the vertical plate 12 encloses a temporary storage space for weights. Optionally, the cross section of the base 11 is rectangular, and the vertical plate 12 is arranged on the four corners of the base 11. The inner side of the vertical plate 12 is arc-shaped, and the curvature of the arc is equal to the curvature of the four corners of the weights 20. The weights 20 are stacked on the temporary storage space for weights, and the two sides of the weights 20 are provided with a card slot 21. The lifting mechanism 30 includes a lifting plate 31 embedded in the upper surface of the base 11, and the lifting and lowering of the lifting plate 31 can drive the weights 20 stacked in the temporary storage space for weights to be lifted and lowered. The suspension mechanism 40 includes a mounting portion 41 installed on the elevator car or the counterweight and a suspension arm 42 connected to the mounting portion 41, and the suspension arm 42 is provided with a card plate 43 corresponding to the card slot 21. When it is necessary to increase the counterweight of the elevator car or the counterweight, the weights 20 are raised by the lifting mechanism 30, and the required number of weights 20 are inserted into the hanging mechanism 40, and the corresponding number of weights 20 are hung on the elevator car or the counterweight by the hanging mechanism 40 to adjust the mass difference between the elevator car and the counterweight.

[0031] The upper end surface of the weight 20 is provided with a convex rib 23 so that there are gaps between the stacked weights 20, which facilitates the measurement personnel to stack the weights 20 in the weight temporary storage space.

[0032] Reference Figure 2The mounting portion 41 includes a transverse plate 411 and a column 412 disposed on the transverse plate 411. Optionally, the number of the columns 412 is two, and they are respectively disposed at both ends of the transverse plate 411. The transverse plate 411 and the columns 412 are integrally formed, and the columns 412 are provided with external threads. The mounting portion 41 is connected to the elevator car or the counterweight, and specifically, the columns 412 are threadedly connected to the bracket of the elevator car or the counterweight.

[0033] The suspension arm 42 is connected to the mounting portion 41 through a connecting rod 49. There are two suspension arms 42, and the distance between the two suspension arms 42 is equal to the width of the weight 20, so as to form a mechanical arm that can hold up the weight 20. A through hole 44 is provided on the suspension arm 42, and the clamping plate 43 passes through the through hole 44. Specifically, the through hole 44 is provided on one end of the suspension arm 42 away from the mounting portion 41. The clamping plate 43 is clamped on the through hole 44, and the clamping plate 43 can move on the through hole 44.

[0034] A limiting plate 451 is provided at one end of the card plate 43 located on the outer side of the suspension arm 42, and a limiting groove 46 corresponding to the limiting plate 451 is provided on the outer side of the suspension arm 42. A handle 48 is provided on the side surface of the limiting plate 451 away from the card plate 43. The measurement personnel can pull the card plate 43 to move in the through hole 44 through the handle 48. A limiting block 452 is provided on the upper surface of the card plate 43, a first limiting rail 47 corresponding to the limiting block 452 is provided on the inner side of the suspension arm 42, and a second limiting rail 22 corresponding to the limiting block 452 is provided on the inner wall of the card slot 21. When the measurement personnel pulls the card plate 43 to move in the through hole 44 through the handle 48, the limiting block 452 moves on the first limiting rail 47 or the second limiting rail 22.

[0035] Specifically, when it is necessary to increase the counterweight of the elevator car or the counterweight, the clamping plate 43 is pulled toward the outside of the suspension arm 42 until the end surface of the clamping plate 43 away from the limit plate 451 is parallel to the inner side surface of the suspension arm 42, or when the end surface of the clamping plate 43 away from the limit plate 451 enters the through hole 44, the weights 20 on the weight temporary storage space are raised, and the weights 20 are clamped between the two suspension arms 42. When the required number of weights 20 are raised to the upper end of the through hole 44, the lifting of the weights 20 is stopped, and the clamping plate 43 is clamped into the clamping groove 21 of the weights 20, and then the lifting plate 31 of the lifting mechanism 30 is lowered. At this time, the required number of weights 20 are lifted by the clamping plate 43 and hung on the hanging wall, so as to achieve the adjustment of the mass difference between the elevator car and the counterweight.

[0036] Optionally, the first limiting rail 47 does not penetrate the inner side of the through hole 44, so that when the card plate 43 is pulled toward the outer side of the suspension arm 42, the card plate 43 will not be pulled out of the through hole 44; at the same time, the limiting plate 451 makes it so that when the card plate 43 is pulled toward the inner side of the suspension arm 42, the card plate 43 will not be pushed out of the through hole 44. That is, the card plate 43 is limited in the through hole 44 and cannot be separated from the through hole 44, so that during the transportation process, the card plate 43 is always on the suspension arm 42, so that the card plate 43 is prevented from being lost during transportation.

[0037] Reference Figure 3 The lower end of the vertical plate 12 is provided with a mounting seat 13, and the mounting seat 13 is provided with a plurality of mounting holes 14. The base 11 is provided with a mounting groove 15 corresponding to the mounting seat 13, and the bottom wall of the mounting groove 15 is provided with a threaded hole 16 corresponding to the mounting hole 14. Optionally, the number of the mounting holes 14 is three, and the three mounting holes 14 are not in a straight line to increase the stability of the vertical plate 12 after installation. The thickness of the mounting seat 13 is equal to the thickness of the mounting groove 15.

[0038] The mounting seat 13 is threadedly connected to the vertical plate 12 , so that the mounting seat 13 and the vertical plate 12 are easy to disassemble, and the temporary storage rack 10 is convenient to transport, thereby avoiding the need for a large space when transporting the temporary storage rack 10 .

[0039] Reference Figure 4 The lifting mechanism 30 further includes a lifting cylinder 32 disposed in the base 11, and the lifting plate 31 is disposed on the lifting end of the lifting cylinder 32. Optionally, the upper surface of the lifting plate 31 is parallel to the upper surface of the base 11.

[0040] The utility model discloses an auxiliary device for measuring balance of an elevator. The specific implementation method is as follows: when the mass difference between the elevator car and the counterweight needs to be adjusted when measuring the balance of the elevator, the weights 20 are temporarily stored in a stacked manner in the temporary storage space of the temporary storage rack 10, and the weights 20 are moved upward and clamped between the two suspension arms 42 of the suspension mechanism 40 through the lifting plate 31 of the lifting mechanism 30. In this process, according to the number of weights 20 to be added, the corresponding number of weights 20 are lifted onto the card plate 43 on the suspension arm 42, and the card plate 43 is clamped into the card slot 21 of the weight 20, and then the lifting plate 31 is lowered. At this time, the weights 20 on the card plate 43 are suspended on the suspension mechanism 40, and the weights 20 under the card plate 43 are separated from the suspension mechanism 40. Since the suspension mechanism 40 is installed on the elevator car or the counterweight through the mounting portion 41, the mass difference between the elevator car and the counterweight is adjusted. In this process, the measurement personnel do not need to move the weight 20, which reduces the labor intensity of the measurement personnel and effectively improves the efficiency of the elevator balance measurement.
