Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a construction lift installed at building construction sites, civil engineering work sites, etc., and used for lifting and lowering construction materials and the like.

Conventional technology Conventionally, at construction sites for multi-story, high-rise buildings, etc., transportation of materials between the ground and required floors, etc.
It is well known to install construction lifts.

Problems to be Solved by the Invention By the way, conventionally known construction lifts have a guide rail installed at the installation location and are guided by the guide rails to raise and lower the loading platform. Loading and unloading from the loading platform, both on the ground and on the upper floors under construction where materials are being distributed, requires loading equipment on both sides, or requires the use of other lifting equipment on site. However, in order to avoid disrupting the flow of work, it is necessary to rely on manual labor. The reality is that it requires a lot of effort, and it is difficult to expect a significant improvement in efficiency.

Therefore, it has been considered to combine a transportation device and a cargo handling device, and it is well known that a simple crane is installed on the loading platform of a truck. In many cases, the loading on the cargo platform becomes a chore. In addition, the truck does not move with the suspended load, and load handling is limited to when the truck is stopped, so even a simple combination cannot be expected to achieve stability and safety. Therefore, when using a construction lift as mechanical equipment that includes vertical movement, even if a crane is simply loaded, stable work cannot be performed, and the lift cannot perform a dual purpose.
In view of these problems, the present invention aims to improve lifting efficiency by shortening the loading and unloading time of loads and shortening the lifting cycle time, as well as reducing the labor involved in loading and unloading loads. The purpose of this invention is to provide a construction lift that can be used for construction purposes.

Means for Solving the Problems The present invention has the following technical means for achieving the above object. In other words, in a construction lift that combines a lift that moves up and down guided by guide rails and a cargo handling machine,
Two front columns are set up on both sides of the front and a rear column at the center of the rear on the loading platform of the lift, and a rigid frame is formed using spliced material, and a T-shaped A support frame is erected, and a loading/unloading crane is attached to the support frame. It is characterized by consisting of.

Function Guide rails are erected at the lift installation locations at construction sites, and loading platforms used to transport materials between the ground and the required floors are guided up and down by the guide rails. The work of loading and unloading materials onto the loading platform can be carried out efficiently and easily using the loading/unloading crane attached to the rigid frame on the loading platform. Since the lift is supported by the carrier, the effective area of the loading platform is not sacrificed, and the lift with lifting equipment can serve both functions. (Line break) As a result, the lifting cycle time of the intended purpose lift is shortened, and the lifting efficiency is greatly improved.

Example An embodiment of the present invention will be described with reference to the drawings.

In Figures 1 to 3, 1 is a guide rail, 2 is a loading platform, and loading platform 2 is a guide rail 1.
It is guided up and down by the guide. The loading platform 2 has two columns 3, 3 on both sides of the front and a column 4 at the center of the rear, and the tops of these columns are connected to a column joint material 5.
A rigid frame 6 which is triangular in plan view and connected by
A T-shaped support frame 7 is horizontally installed in the upper part of the frame body 6 so as to be supported by three pillars. The support frame 7 is connected to each support column 3, 4 by means of a cylindrical member 8 and a fixing pin at each end.
It can be configured to be able to be raised and lowered at a required height position. Reference numeral 9 denotes a loading/unloading crane, and this crane 9 has a telescoping arm 11 attached to a revolving frame 10 so as to be slidable back and forth, and a trolley hoist (chain block) 12 is moved on the telescoping arm 11 in the direction of the arm. It can be worn freely. The swing frame 10 of this crane 9 is rotatably attached to the support frame 7. That is, as shown in FIGS. 4 and 5, the rotating frame 10 is rotatably attached to the support frame 7 by a rotating shaft 13, and the rotating frame 10 has a guide roller 14 on its upper part. However, support rollers 15 are provided at their lower portions, and the telescoping arm 11 is attached to the rotating frame 10 so as to be slidable back and forth by these guide rollers 14 and support rollers 15. Further, the trolley hoist 12 is supported by the telescoping arm 11 via trolley moving wheels 16, and the trolley hoist 12 is movable in the direction of the telescoping arm 11.

In a device configured as described above, in order to load materials onto the loading platform 2, the trolley hoist 12 of the crane 9 lifts the materials and transfers them onto the loading platform 2, and also unloads the materials from above the loading platform 2. In this case, the materials may be hoisted up by the trolley hoist 12 of the crane 9 and moved to a predetermined location outside the loading platform 2.
Therefore, the work of loading and unloading materials onto the loading platform 2 that moves up and down between the ground and the required floors can be done without manual labor.
This can be done efficiently and easily using the crane 9, and not only can the entire upper surface of the loading platform 2 be utilized, but also the telescopic arm 11 can be accommodated within the frame 6 so that the lifting and lowering operations of the lift are not obstructed. , and can maintain overall stability. From this, it is possible to significantly shorten the lifting cycle time, and by increasing the lifting speed of the loading platform 2, the lifting efficiency can be improved.

Note that the possible range of loading and unloading operations using the trolley hoist 12 of the crane 9 can be widened by rotating the revolving frame 10, extending and contracting the telescoping arm 11, and moving the trolley hoist 12. Loading and unloading work can be carried out more conveniently and efficiently.

Effects of the Invention Since the present invention has and operates the technical means as described above, the loading capacity of the loading platform of the lift is ensured and the lift is lifted and lowered, and at the stop position of the lift, the lift is perpendicular to the guide rail. Work in the front and rear directions of the loading platform can be carried out stably even when work is performed in the direction of transport. Therefore,
The structure of the present invention is to add a rigid frame to a construction lift, which is mechanical equipment that can move in the vertical direction, to mount a crane three-dimensionally above the loading platform, and to increase the load capacity. In addition to ensuring stable operation, the function of both a lift and a crane is realized, and as intended, it shortens loading and unloading time, shortens lifting cycle time, and improves lifting efficiency. This has the effect of reducing the amount of effort required for loading and unloading cargo, making it an extremely important contribution to industry.
