Description

Main machine lifting device for elevator

Technical Field

The invention relates to the field of elevator installation, in particular to a main machine lifting device for elevator main machine installation. The elevator main machine can be lifted to a desired installation position by means of the main machine lifting device.

Background

An elevator machine, such as a traction machine, typically needs to be placed at the top of the hoistway. In the process of installing the elevator main machine, a base is generally manufactured, the elevator main machine is fixed on the base, and then the elevator main machine is lifted to a specified installation position through a lifting mechanism. However, in the case of a limited height of the top floor of the shaft, especially in the case of a household elevator shaft in a private home, the main machine is often located within a small distance from the top of the shaft due to the small shaft space. It is difficult to lift the elevator main machine to a designated installation position by the lifting pedestal, and it is usually only possible to lift to a height lower than the ideal installation position. How to safely and efficiently lift an elevator main machine to the top of a shaft is a problem which always troubles elevator manufacturers and elevator installers.

Disclosure of Invention

The technical problem underlying the present invention is therefore to provide an improved main machine hoisting device which is capable of safely and efficiently raising an elevator main machine to an installation position at the top of a hoistway.

The technical problem is solved by a main machine hoisting device for an elevator, which main machine hoisting device has a hoisting mechanism for hoisting the main machine of the elevator and a load bearing seat for bearing the main machine of the elevator. According to the solution of the invention, the main unit hoisting device also has a support for supporting the load carrier, which support is supported below the load carrier, wherein a hoisting member is arranged on the support, wherein the hoisting mechanism exerts a hoisting force on the hoisting member such that the main unit hoisting device can be moved along the guide rails of the elevator. Compare with prior art hoist mechanism direct action on the elevator host computer, hoist mechanism acts on the lifting member of support, because the lifting member is settled and is bearing seat below and bear the seat and have the difference in height, therefore can bear the seat and improve to the well top for the installation of elevator host computer is more high-efficient more convenient.

According to a preferred embodiment of the invention, the stand has at least two tripods arranged parallel to one another, preferably right-angled tripods, although non-right-angled tripods are also conceivable. The first right-angle side of the right-angle tripod supports the bearing seat, the second right-angle side of the right-angle tripod is parallel to or attached to a guide rail of the elevator, and the vertex of the right-angle tripod, which is opposite to the first right-angle side, is connected through a connecting rod. It is also preferred that at least one guide rail fixing element is arranged on the second right-angle side of the right-angle tripod for movably fixing the bracket on the guide rail of the elevator. It is further preferred that two right-angled tripods are provided to abut against the guide rails of the elevator, that two guide rail fixtures are arranged on each second right-angled side of the two right-angled tripods, and that the guide rail fixtures on the different second right-angled sides are aligned with each other, so that the carriage can be moved more firmly on the guide rails. The elevator is characterized in that the guide rail of the elevator is a T-shaped guide rail, and the support can be fixed on the guide rail along the guide rail in a movable mode through the guide rail fixing piece, so that the host lifting device can move stably along the guide rail, and the risk of shaking or falling of the host is effectively reduced. It is also conceivable to arrange the lifting means on the connecting rod of the support, for example, in particular in the form of a lifting eye and in the middle of the connecting rod, on which lifting eye the hook of the lifting mechanism can be directly hooked, thus lifting the entire main unit lifting device.

According to a further preferred embodiment of the invention, at least two main machine connecting holes, preferably four main machine connecting holes, are provided in the load carrier for fixed connection to the elevator main machine. The host can be fixed on the bearing seat through the host connecting hole by using a bolt. It is also conceivable to provide the carrier plate with a recess for the passage of the lifting means.

According to another preferred embodiment of the invention, the elevator to which the invention relates is preferably a home elevator, because the home elevator hoistway is narrow, the above-described main machine lifting device is more required to lift the elevator main machine to the top of the hoistway to complete the installation of the elevator main machine.

Drawings

Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. The attached drawings are as follows:

fig. 1 shows a schematic view of a main machine lifting device according to the invention.

Detailed Description

As shown in fig. 1, the main machine lifting device according to the invention mainly comprises a load bearing seat 1 and a support frame 2, wherein the load bearing seat 1 is used for bearing the main machine of the elevator and transporting the main machine to an installation position, and the support frame 2 is supported below the load bearing seat 1. The support 2 is composed of two right-angle tripods 5 and a connecting rod 6, the two right-angle tripods 5 are arranged in parallel, the right-angle sides are supported below the bearing seat 1, and the vertexes opposite to the bearing seat 1 are connected through the connecting rod 6. At least one guide rail fixing element 7 for fixing to a T-shaped guide rail of the elevator is arranged on the other leg of each leg (i.e. the leg which does not support the support base). Preferably, two rail mounts 7 are arranged on each right-angled side (as shown) and are arranged opposite one another. The entire main machine hoisting device can be moved stably on the T-shaped guide rails of the elevator by means of the guide rail fixing 7. The guide rail fixing piece 7 is fixed on the other right-angle side of the bracket 2 through a bolt.

On the connecting rod 6, a lifting element 4 is arranged, which lifting element 4 is designed according to the invention as a lifting eye. A lifting mechanism, such as an electric hoist, is arranged at the top of the elevator, and a hook of the electric hoist is hung in a hole of the lifting hanging hole, so that the whole host lifting device is lifted.

Host machine connecting holes 3 are arranged at corresponding positions on the bearing seat 1, and the elevator host machine is fixed on the bearing seat 1 through the host machine connecting holes 3 by bolts. The elevator machine is lifted to the corresponding position by the lifting force exerted by the lifting mechanism on the lifting eye. A recess 8 for the passage of the lifting mechanism is also provided on the carrier base 1. Because guide rail mounting 7 is movably attached to support 2 on the T-shaped guide rail, the host can always walk along the track in the lifting process, and the risk of shaking or falling of the host is effectively reduced. Because bear seat 1 highly be higher than the lifting hole in vertical direction, so can promote the elevator host computer to construct the position of equidistance with the lifting, can directly promote the elevator host computer to the mounted position at top promptly, furthest reduces the manpower and pays out for whole lift process is more high-efficient.

Although possible embodiments have been described by way of example in the above description, it should be understood that numerous embodiment variations exist, still by way of combination of all technical features and embodiments that are known and that are obvious to a person skilled in the art.
