Technical Field

The present invention relates to a lifting device for lifting a heavy object and a lifting and carrying method using the lifting device.

background

conventionally, when a heavy object such as a hoist is transported, the heavy object is lifted to a predetermined height using a lifting device including a crane such as a chain block, and then transported to a desired position by being moved on a load sheave beam (rail) by a load sheave or the like.

as an example of the hoisting apparatus, there is a hoisting apparatus of a hoisting machine of an elevator disclosed in patent document 1. For example, the abstract of the specification of the document describes "a hoisting bracket, a method of installing a hoisting machine, and a hoisting machine capable of ensuring a hoisting amount when hoisting the hoisting machine by a simple mechanism", and describes "the hoisting bracket includes a first member, a second member, a first adjusting mechanism, and a second adjusting mechanism. The first adjusting mechanism is configured to be capable of adjusting the position of the suspension point in the horizontal direction. The second adjusting mechanism is configured to be capable of adjusting the position of the suspension point in the vertical direction. The hoisting bracket is attached to two positions except for the top portion of the hoist in the vertical direction ".

as is apparent from fig. 1 and 2 of the patent, since the height of the machine room of the elevator is often lower than the size of the hoist (for example, the height of the machine room is about 2 m with respect to the size of the hoist larger than 1 m), in patent document 1, two hoisting brackets attached to the side surface are used as hoisting points instead of using the hoisting point at the top of the weight, thereby securing an installation space of the chain block.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object thereof is to provide a lifting apparatus that can extend a travel distance caused by one lifting using a relatively short rail, and a lifting and conveying method using the lifting apparatus.

In order to achieve the above object, a hoisting device for a heavy object according to the present invention includes a substantially horizontal first rail, a substantially horizontal second rail supported at one end thereof by the first rail, a first gate-shaped structure supporting one end of the first rail, a second gate-shaped structure supporting the other end of the first rail, a support member supporting the other end of the second rail, a first carriage moving on the first rail, a second carriage moving on the second rail, a third carriage movably provided on the first rail and the second rail, and a crane provided on each carriage and hoisting the heavy object.

Another hoisting device for heavy objects according to the present invention includes a substantially horizontal first rail, a substantially horizontal second rail supported at one end by the first rail, a first gate-shaped structure supporting one end of the first rail, a second gate-shaped structure supporting the other end of the first rail, a support member supporting the other end of the second rail, a first carriage and a third carriage that move on the first rail, a second carriage that moves on the second rail, and a crane provided in each carriage and hoisting the heavy object.

effects of the invention

according to the weight hoisting device and the hoisting method of the present invention, since the weight is moved from the additional track, the weight can be transported without temporarily placing the weight lifted by the crane on the ground when transporting the weight, and the moving distance of the weight is extended. Thus, the invention can reduce the working hours of the moving operation of the hoisting device and reduce the construction process and the construction cost.
