Description

Technical Field

[0001] The invention relates to a vibration reduction device for a lifting elevator, in particular to a mounting device for reducing the vibration transmitted outwards by an elevator main unit. Background Art

[0002] The elevator mainly includes the car, traction system, weight balance system and electric traction system, and the traction motor, that is, the elevator main unit, is the most important component of the electric traction system. In order to ensure the accuracy and stability of the car during movement, the elevator main unit and its working end need to be kept at a certain verticality and horizontality; on the other hand, in order to protect the elevator main unit and reduce the vibration caused by it, the elevator main unit needs to be installed on the vibration-damping seat. However, due to the different specific conditions of different elevator installation locations, their horizontality is also different. When the elevator main unit and the vibration-damping seat are installed in these locations, it will inevitably affect the horizontality of the elevator main unit and its working end; at the same time, due to the uneven weight of the elevator main unit, the pressure on the vibration-damping seat at various locations is also different, and the vibration-damping seat is installed with an elastic vibration-damping structure. Therefore, after the elevator main unit is installed on the vibration-damping seat, the vibration-damping seat will be tilted, thereby aggravating the tilt of the elevator main unit and its working end. Summary of the invention

[0003] The object of the present invention is to provide a vibration reduction adjustment installation device capable of adjusting the horizontality of an elevator main engine, so as to ensure the safety and stability of the elevator operation.

[0004] The horizontally adjustable elevator main engine vibration reduction device described in the present invention includes a fixed base and an adjustment seat arranged above the base, a gap is left between the bottom surface of the adjustment seat and the top surface of the base, an elastic vibration reduction component providing vibration reduction capability is provided at the top of the adjustment seat, a support plate is provided at the bottom of the elastic vibration reduction component, an adjustment buffer pad and an adjustment pressure plate are provided at the bottom of the support plate in sequence, an elastic member is provided at the bottom of the adjustment pressure plate, the bottom of the elastic member abuts against the top surface of the base, an adjustment screw and an adjustment nut are further provided, the adjustment nut is fixedly arranged on the adjustment seat, the adjustment screw is threadedly connected to the adjustment nut, and the end portion passes through the adjustment seat and the elastic vibration reduction component and abuts against the adjustment pressure plate.

[0005] The horizontally adjustable elevator main engine vibration reduction device has a plurality of bases arranged in parallel, each base is respectively equipped with an adjustment seat, and adjacent adjustment seats are fixedly connected to each other through a connecting plate.

[0006] The horizontally adjustable elevator mainframe vibration reduction device described in the present invention has a base arranged on the ground where the elevator mainframe is installed, and an adjustment seat supporting the elevator mainframe is arranged above the base. The number of the base and the adjustment seats thereon can be arranged in multiples according to the installation requirements of the elevator mainframe, and the adjacent adjustment seats are connected by a connecting plate so that all the adjustment seats are connected as a whole. An elastic vibration reduction component, a support plate and an elastic member are arranged in sequence between each adjustment seat and the base. The elastic vibration reduction component can be a multi-layered elastic vibration reduction pad, or other existing elastic vibration reduction structures, which are not described in detail here. Multiple elastic members can also be arranged between the same adjustment seat and the base, as well as an adjustment pressure plate and an adjustment member for driving the deformation of the elastic member. The base is an I-beam, which has a simple structure, high structural strength, large weight and high stability, and can simplify the structural complexity of the device and improve the working stability of the elevator mainframe. The adjustment seat is an inert mass block, which can be made of, for example, a high-density rigid material, or cast iron, steel structure, concrete, etc., to improve its load-bearing capacity and maintain the stability of the elevator mainframe during operation.

[0007] Before the elevator is installed, all the elastic parts in each adjustment seat have basically the same vertical thickness. After the elevator main unit is installed on the adjustment seat, due to the problem of ground flatness and the different weights of the elevator main unit at different positions, the elastic vibration damping components and elastic parts will be compressed to different degrees, resulting in different levels of height of their top surfaces, which also causes the elevator main unit to be unable to maintain the required horizontal state; for this reason, the adjustment screw can be rotated to change its pressure on the adjustment pressure plate, so that the elastic vibration damping components and elastic parts undergo different degrees of deformation, that is, different degrees of compression and vertical height are formed, until the top surfaces of all elastic parts are at the same level, or until the top surface of the adjustment seat is adjusted to a horizontal state, and the elevator main unit installed on the adjustment seat also reaches the required horizontality. Therefore, through the horizontally adjustable elevator main unit vibration damping device, the horizontality of the elevator main unit and its working end can be effectively guaranteed, thereby ensuring the safety and stability of the elevator operation.

Before the elevator is installed, all elastic parts in each adjustment seat have basically the same vertical thickness. After the elevator main unit is installed on the adjustment seat, due to the problem of ground flatness and the different weights of the elevator main unit at different positions, the elastic vibration damping components and elastic parts will be compressed to different degrees, resulting in different horizontal heights of their top surfaces, which also causes the elevator main unit to be unable to maintain the required horizontal state; for this reason, the adjusting screw can be rotated to change its pressure on the adjusting pressure plate, so that the elastic vibration damping components and elastic parts undergo different degrees of deformation, that is, different degrees of compression and vertical heights are formed, until the top surfaces of all elastic parts are at the same level, or until the top surface of the adjustment seat is adjusted to a horizontal state, and the elevator main unit installed on the adjustment seat also reaches the required horizontality.

[0018] like Figure 1 , 3 As shown in , 4, the elastic member 5 can be a spring, or a rubber member, or a rubber spring which is cylindrical and has an axial through hole as shown in the figure, and has a simple structure and stable operation. In addition, an adjusting pressure plate 6 is provided on the top surface of the rubber spring, and a pressure column 61 extending into the axial through hole of the rubber spring is provided in the middle of the bottom surface of the adjusting pressure plate, and the rubber spring is provided with a radial limit by the pressure column.
