Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a mainframe installation structure without a machine room. Background Art
[0002] At present, a considerable number of machine room-less elevator traction machines are installed on the machine beam, which is installed in the elevator shaft or on the guide rail. This installation method is relatively easy, has good connection reliability, and is more convenient for later maintenance.
[0003] However, when the winch is directly installed on the crane beam, its vibration is also transmitted to the crane beam when the winch is working. In most cases, this vibration appears as low-frequency vibration that the human ear is more sensitive to, and this low-frequency vibration is more likely to be transmitted along the shaft structure such as concrete and steel beams, which is easy to cause complaints from residents near the winch. Therefore, customers have put forward higher requirements for the shock absorption performance of the winch and the crane beam.
[0004] In addition, considering the ease of maintenance, the traction sheave of the traction machine is often cantilevered, which results in the ineffectiveness of installing the shock-absorbing components directly on the lower part, and may even cause the traction sheave to tilt with the change of elevator load. The same problem will occur with the hoist beam. Since the traction machine is often located on the side of the hoist beam, if the shock-absorbing components are installed directly on the lower part of the hoist beam, the hoist beam may even tip over.

[0034] In this embodiment, the bolt 2 is a locking bolt having two opposing nuts.
[0035] In this embodiment, a machine beam auxiliary support frame 8 is also installed on the lower middle side of the machine beam 1. The machine beam auxiliary support frame 8 can support the machine beam from the bottom and be fixed on the car guide rail. In this way, the force on the machine beam 1 is changed from the conventional two-point force to a three-point (triangle) force.
[0036] In this embodiment, the shock absorbing assembly 6 includes a rectangular bottom plate 601, an outer tube 602, a rectangular top plate 603, an inner tube 604, a lower positioning ring 605, an upper positioning ring 606, a shock absorbing spring 607, a damping block 608 and a cover body 609.
