Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a truck system installed on an inclined surface.

[0002]

2. Description of the Related Art When performing work on an inclined surface such as roof construction, a work carriage can be installed and moved by using a steel frame of a main building at the time of new construction, but an existing roof material such as a slate or the like can be installed during repair work. The roofing material for renovation work must be temporarily placed on the folded plate and transported, or the existing roofing material must be removed and temporarily placed on the main building for transportation. For this reason, there is a danger that an accident may occur in which the existing roofing material is stepped on during the moving operation, or an accident may occur in which the wind may cause the vehicle to fall or fall.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a safe and efficient work system for performing dangerous work on an inclined surface at a high place such as a roof work regardless of new construction work or renovation work. It is an object of the present invention to provide a dolly system that can be raised and is lightweight and easy to handle.

[0004]

In a trolley system installed on an inclined surface, a gantry having a loose hole which is installed in an inclined direction and whose position can be adjusted, and a plurality of rails laid in a direction perpendicular to the gantry are provided. A bogie system comprising a bogie having a lower frame moving on a rail, an upper frame arranged horizontally, and a joining material connecting the lower frame and the upper frame.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

<A> Overall System Configuration FIG. 1 is a perspective view showing a state where a gantry 2 and a rail 3 according to the present invention are installed on a new or existing roofing material 1. FIG. 2 is a perspective view showing a state where a cart 4 according to the present invention is installed on the rail 3. In a bogie system installed on an inclined surface having a maximum inclination angle of a roof, a gantry 2 installed in an inclined direction and having a position-adjustable loose hole 5, and a plurality of rails laid in a direction orthogonal to the gantry 2 3, a bogie system including a bogie 4 having a lower frame 4b moving on the rail 3, an upper frame 4a arranged horizontally, and a joining material 4c connecting the lower frame 4b and the upper frame 4a.

<B> Mount The mount 2 is a rail support using, for example, an aluminum material. At a predetermined position in the extension direction of the gantry 2, there is provided a position-adjustable loose hole 5 for fixing the gantry 2 by using a screw 7 or the like provided on the existing roofing material 1. Since the gantry 2 is made of lightweight aluminum and has a predetermined length corresponding to the size of the trolley 4 described below, the trolley 4 receives the load placed on the trolley 4 with an evenly distributed load, and 1
The shape is such that the load on the load can be dispersed.

<C> Rail The rail 3 may be, for example, an aluminum steel square pipe. On both sides (upper and lower sides of the inclined surface) of the rail 3 mounted on the gantry 2 at predetermined intervals, one piece of a hinge type fixing plate 6 is fixed in advance by an arbitrary method such as welding. The rail 3 and the gantry 2 have a detachable structure by fastening another piece of the fixing plate 6 to the gantry 2 with, for example, screws 7.

<4> Bogie The bogie 4 is formed by an upper frame 4a, a lower frame 4b, and a joining material 4c.
The horizontal structure of the upper frame 4a is ensured by adjusting the length and angle of the joining material 4c. The upper frame 4a and the lower frame 4b are each made of a frame material or the like having a rectangular planar shape, and are connected by a reinforcing material 4d as necessary. A plurality of wheels 8 for traveling on the rails 3 are provided on the bottom surface of the lower frame 4b, and hold the cart 4 via the wheels 8. The upper frame 4a, the lower frame 4b, and the joining material 4c are all made of lightweight aluminum steel pipe square pipes, so that the gantry 2 and the bogie 4 themselves can be easily disassembled and transported.

[0010]

The operation of the truck system according to the present invention will be described below. According to this system, either new construction work or renovation work can be adopted, but the case of renovation work will be described below.

<A> Installation of a base Using a screw 7 of a roofing material 1 laid on a main building (a crossbar receiving a slack in parallel with a mound and an eave, not shown) constituting a roof portion. The position of the gantry 2 is adjusted along the loose hole 5 provided on the gantry 2, and the gantry 2 is installed and fixed between the purlins along the inclined surface of the roof. (FIG. 1) The installation interval of the gantry 2 is, for example, 1 m to 1.5 m. The number of the gantry 2 to be installed may be determined in consideration of work efficiency and economy. That is, if the gantry 2 is provided at many places on the roofing material 1 and the number of times of disassembly and conversion of the gantry 2 is reduced, the work efficiency is improved, but a large number of gantry 2 are required. vice versa,
If the number of times of disassembly and conversion of the gantry 2 is increased, the work efficiency is reduced, but the required number of gantry 2 is reduced and it becomes economical.

<B> Laying the rails The rails 3 are laid on the gantry 2 in the orthogonal direction. A piece of a hinge type fixing plate 6 is attached to the rail 3 in advance. The other piece of the fixing plate 6 in a free state is fastened to the gantry 2 by, for example, a screw 7, so that the rail 3 and the gantry 2 can be detachably and integrally fixed.

<C> Installation of the cart The cart 4 is installed on the rail 3. The cart 4 is previously formed integrally with an upper frame 4a, a lower frame 4b, and a joint member 4c using a lightweight aluminum steel pipe square pipe, and a wheel 8 is provided on the bottom surface of the lower frame 4b.
Are installed, and the cart 4 is installed on the rail 3 via the wheels 8. Alternatively, the truck 4 may be assembled and dismantled on site. The upper frame 4a on which the members for construction are mounted must be assembled so that the horizontal is secured by adjusting the length and angle of the joining material 4c.

<4> Movement of truck, dismantling and conversion of rails and gantry The truck 4 is moved along the rails 3 to the construction site where the roofing material 1 is replaced. The moving method may be either manual or using a machine. After the completion of the construction, the carriage 4 is moved along the rail 3 again to the next construction place. The rail 3 and the gantry 2 in the construction end section are dismantled, removed, and transported to the next construction site. The disassembly and removal of the rail 3 can be easily performed by removing the screw 7 connecting and fixing the rail 3 and the gantry 2. Subsequently, the gantry 2 fixed using the screws 7 of the roofing material 1 is removed. The removed base 2 is transported together with the rail 3 to the next construction site.

[0015]

Since the present invention has been described above,
The following effects can be obtained. <A> The gantry, rail, and bogie are lightweight and easily dismantled and diverted, so they can be easily moved. <B> Since the work can be performed on the inclined surface in a horizontal state, the work can be performed safely and efficiently.
