Abstract
Description
Technical Field
[0001] The utility model relates to the field of elevator vibration reduction, in particular to a disc spring vibration reduction device for elevator main engine installation. Background Technique
[0002] In the existing machine-roomless elevator, the main engine and the load-bearing beam are rigidly connected or connected with rubber pads. The effect of rigid connection is poor, and after the rubber of the rubber pad ages, it is very troublesome to replace in the machine-roomless environment. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a disc spring vibration reduction device for elevator main engine installation with good vibration reduction effect, long service life, simple installation and low cost.
[0004] In order to solve the above technical problems, the solution of the utility model is as follows:
[0005] A disc spring vibration reduction device for elevator main engine installation includes a mounting block connected to the main engine. An installation plate is arranged at the lower end of the mounting block. The installation plate is placed on the upper end of the load-bearing beam. A bolt hole is formed in the mounting block. A screw rod is arranged in the bolt hole. The screw rod passes through the installation plate and is connected to a nut arranged in the load-bearing beam. A first disc spring is arranged between the screw rod and the mounting block. A second disc spring and a third disc spring are arranged between the mounting block and the installation plate.
[0006] Preferably, the opening of the first disc spring faces downward.
[0007] Preferably, the opening of the second disc spring faces upward, and the opening of the third disc spring faces downward.
[0008] Preferably, the second disc spring and the third disc spring are symmetrically arranged.
[0009] Preferably, the nut is a double nut.
[0010] Preferably, the double nut is provided with a clamping spring washer and is tightened at the back.
[0011] Compared with the prior art, the utility model sets an installation plate on the load-bearing beam for installing the main engine, and directly connects the connection block between the installation plate and the main engine with bolts, passes through the connection plate and is connected to the load-bearing beam, and sets a first disc spring between the screw rod of the bolt and the mounting block, and sets a second disc spring and a third disc spring between the mounting block and the installation plate for vibration reduction, so as to transfer the vibration of the main engine during the operation of the elevator to the wall or the guide rail, thereby achieving the reduction of the vibration feeling during the operation of the elevator and making the customer experience better. The utility model has good vibration reduction effect, simple installation, low cost and long service life. Description of the Drawings

[0015] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the following described various embodiments of the present utility model can be combined with each other as long as they do not conflict with each other.
[0016] Refer to Figures 1-3 , a disc spring shock absorption device for elevator main engine installation of the present utility model includes a mounting block 2 connected to the main engine 1. A mounting plate 3 is arranged at the lower end of the mounting block 2. The mounting plate 3 is placed on the upper end of a bearing beam 4. A bolt hole is formed in the mounting block 2. A screw rod 5 is arranged in the bolt hole. The screw rod 5 passes through the mounting plate 3 and is connected to a nut 6 arranged in the bearing beam. A first disc spring 7 is arranged between the screw rod 5 and the mounting block 2. A second disc spring 8 and a third disc spring 9 are arranged between the mounting block 2 and the mounting plate 3.
[0017] In the present utility model, the opening of the first disc spring 7 faces downward. The opening of the second disc spring 8 faces upward. The opening of the third disc spring 9 faces downward. The second disc spring 8 and the third disc spring 9 are symmetrically arranged. The disc springs (the first disc spring 7, the second disc spring 8 and the third disc spring 9) have a large stiffness and strong buffer and shock absorption capabilities, can withstand large loads with small deformations, and effectively improve the shock absorption effect.
[0018] The double nuts are tightened back-to-back through a spring clip 10, and the spring clip 10 can play a role in shock absorption and buffering.
[0019] Specifically, the present utility model is to set a mounting plate on the bearing beam for installing the main engine, connect it to the bearing beam by directly connecting the connecting block between the mounting plate and the main engine with bolts, arrange a first disc spring between the screw rod of the bolt and the mounting block, and arrange a second and a third disc spring between the mounting block and the mounting plate for shock absorption, so as to transfer the vibration of the main engine during the operation of the elevator to the wall or the guide rail, thereby reducing the vibration feeling during the operation of the elevator and making the customer riding experience better.
[0020] The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
