Description

Technical Field

[0001] The utility model relates to a machine shelf beam, in particular to a machine shelf beam with a frame structure. Background Art

[0002] For machine room-less elevators, the elevator traction machine is generally fixed to the top of the shaft through a machine beam. At present, the installation of the machine beam generally requires a hole to be reserved in the shaft during on-site construction, and the end of the machine beam is buried in the shaft wall during installation. The overall installation of the machine beam is inconvenient; moreover, the existing machine beam has a poor shock absorption effect. Since the machine beam is installed in the wall at the top of the shaft, the traction machine will generate large vibration and noise during operation, which has a greater impact on the users on the roof. Therefore, the existing technology has the problems of inconvenient installation and unsatisfactory shock absorption effect. Utility Model Content

[0003] The purpose of the utility model is to provide a frame structure machine shelf beam. The utility model has the characteristics of convenient installation and improved shock absorption effect.

[0004] The technical solution of the utility model is as follows: a frame structure shelf beam, comprising a shelf beam channel steel frame erected above a counterweight guide rail, one end above the shelf beam channel steel frame is provided with a counterweight guide rail top plate matching the counterweight guide rail; the other end above the shelf beam channel steel frame is provided with a shelf plate, a shock-absorbing pad is provided above the shelf plate, a rubber ring is provided between the shock-absorbing pad and the shelf plate, and a shock-absorbing pad is provided above the shock-absorbing pad; reinforcing ribs are provided between the shelf plate and the side surface of the shelf beam channel steel frame; a counterweight rope head assembly located on the side surface of the shelf plate is also provided above the shelf beam channel steel frame.

[0005] In the aforementioned frame structure shelf beam, the shock-absorbing pad and the shelf plate are connected to the shelf beam channel steel frame via bolts.

[0006] In the aforementioned frame structure shelf beam, the shelf beam channel steel frame includes two long channel steels distributed front and back, both ends of the two long channel steels are connected with side channel steels by bolts, and an intermediate reinforcement plate corresponding to the position of the shelf plate is also provided between the two long channel steels.

[0007] In the aforementioned frame structure shelf beam, the long channel steel includes a channel steel body, pads are provided at both ends of the channel steel body, notches corresponding to the position of the counterweight rope head assembly are provided at the upper and lower ends of the channel steel body, and reinforcing ribs are provided on both sides between the two notches.

[0008] In the aforementioned frame structure machine shelf beam, the counterweight rope head assembly includes a counterweight channel steel, and a counterweight rope head plate is provided above the counterweight channel steel.

[0009] In the aforementioned frame structure shelf beam, the shelf plate includes a plate body, and an opening cooperating with the traction rope is provided on the right side of the plate body.

[0010] In the aforementioned frame structure shelf beam, the shock-absorbing pad includes a shock-absorbing pad body, and the shock-absorbing pad body is also provided with a through hole that cooperates with the traction rope.
