Abstract

A main machine base mounting structure of a steel belt-type machine room-less elevator, comprising a main machine base (4). The main machine base (4) is fixed on a load beam (7); first support plates (5) and a second support plate (6) are fixed under the load beam (7); the main machine base (4) comprises a main machine base beam (4.1) and a guide wheel fixing plate (4.2); there are two first support plates (5), which are respectively fixedly connected to the lower sides of two ends of the load beam (7) and are oppositely disposed; there is only one second support plates (6) welded onto the lower side of the load beam (7); the first support plates (5) are connected to an auxiliary guide rail (3); and the second support plate (6) is connected to a main guide rail (2). In the present solution, the mounting structure of the main machine base (4) is fixed to the main guide rail (2) and the auxiliary guide rail (3) to be independent of a hoistway building structure, such that during construction, the construction of the hoistway can be carried out conventionally, thus saving hoistway construction costs. In addition, the simple mounting structure enables the stable operation of the elevator and makes the installation and maintenance convenient.

Description

Mounting structure of main frame of steel belt elevator without machine room

Technical field

The invention belongs to the technical field of elevator equipment, and specifically belongs to a machine room-less steel belt elevator main base installation structure.

Background technique

The main frame structure of the machine room-less elevator in the prior art is closely related to the building itself. For example, it is necessary to reserve a hole in the installation hoistway and pour cement to form a ring beam; It is fixed together with the building wall, which relies a lot on the building, and when the hoistway wall is constructed, the space limitation and other factors make the construction more inconvenient and increase the construction cost.

Summary of the invention

The invention provides a machine room-less steel belt elevator main base installation structure, so as to achieve the purpose of stabilizing the operation of the elevator and reducing the degree of dependence of the elevator structure on the building.

A main frame installation structure of a steel belt elevator without a machine room, which is characterized in that it comprises a main frame, the main frame is fixed on a bearing beam; and a pallet 1 and a pallet 2 are fixed under the bearing beam; The main frame structure includes a main frame beam and a guide wheel fixing plate; the one of the supporting plates is two pieces, and they are respectively fixedly connected to the lower sides of the two ends of the load-bearing beam, and are arranged opposite to each other; the two supporting plates are one piece , Welded on the lower side of the load beam; the first pallet is connected with the main rail; the second pallet is connected with the auxiliary rail.

Further, the pallet one and the pallet two include a pallet body, and a reinforcing rib is connected to the pallet body.

Further, a host and an anti-rope device are installed on the host base.

Further, the first and second pallets are connected to the main rail and the secondary rail through bolts and pressure guide plates.

The beneficial effects of the present invention:

In the present invention, the installation structure of the main base is fixed on the main guide rail and the auxiliary guide rail, so that it is not related to the hoistway building structure. During construction, the hoistway can only be constructed by conventional construction, which not only saves the cost of hoistway construction, but also the simple installation structure makes the elevator run stably; installation and maintenance are more convenient.
