  Next, an example of a method for installing the heavy article transport device 10 on the stairs 11 will be described. First, the lower base 60 is installed on the lower floor 13, and the upper base 50 is installed on the landing 14. Next, the worker passes the pair of rails 20 to the lower base 60 and the upper base 50 and fixes the lower layer side rail member 22 of both rails 20 to the connecting member 64 of the lower base 60. Thereby, the rail 20 is connected to the undercarriage 60 so as to freely rotate in a direction away from the stairs 11.

  Next, both rails 20 are rotated in a direction away from the staircase 11 with the support shaft 65 as a fulcrum, and the inclination angles of the rails 20 are adjusted. When both the rails 20 have a desired inclination angle, the worker fastens the gantry side fastening hole 53a and the rail side fastening hole 53b with the bolt 54 and the nut. When both rails 20 are longer than the length between the lower gantry 60 and the upper gantry 50 and the two rails 20 cannot be adjusted to a desired inclination angle, the two rails 20 are connected to the gantry side fastening holes 53a and the rails. By adjusting the communication position with the side fastening hole 53b, it is connected to the upper base 50 with an inclination angle close to a desired inclination angle. In addition, the installation method of the heavy article conveyance apparatus 10 is not limited to an above-described method.

Specifically, the worker installs the intermediate support base 80 on an arbitrary tread surface 11a, and holds the lower wall 20b of the rail 20 positioned above the clip 20 with the clip 82.

  Next, the worker installs the carriage 30 on both rails 20 and fastens the free end of the rope 71 of the hoisting machine 70 to the carriage 30 via the fixed pulley 26. Next, the worker adjusts the overlap margin between the inclined portion side stay 42 and the horizontal portion side stay 41 of the telescopic device 40 to position the top plate 33 horizontally.

  Next, the operation of the heavy article transport device 10 will be described by taking as an example the case of transporting the heavy article 12 from the lower floor 13 to the landing 14. The worker places the heavy load 12 on the top plate 33 of the carriage 30 and operates the hoisting machine 70.

  When the carriage 30 is pulled to the landing 14, the worker stops the operation of the hoisting machine 70, removes the heavy load 12 from the carriage 30, and the series of operations ends. In addition, if the inclination angle of the rail 20 changes during conveyance of the heavy article 12, the limit switch 90 detects that the inclination of the rail 20 has changed.

  When the limit switch 90 detects that the inclination of the rail 20 has changed, the operation of the hoisting machine 70 is stopped based on the detection information. Furthermore, the speaker 72e emits an alarm sound or a pre-recorded voice to inform surrounding workers that the inclination of the rail 20 has changed and call attention.

  That is, since both the rails 20 can be positioned at an arbitrary inclination angle regardless of the inclination angle of the stairs 11, when the length of the rail 20 is longer than the length between the upper and lower frames 50, 60 due to a design error of the building, The rail 20 can be easily laid by absorbing the error only by adjusting the upper platform 50 side of the rail 20 in the vertical direction. Therefore, it is possible to easily perform the installation work of the heavy material transport device 10 on site. Furthermore, the heavy article transport device 10 can be easily installed on stairs having different specifications.

  Moreover, the 1st fastening part 53 is a simple structure provided with the base side fastening hole 53a and the rail side fastening hole 53b. Therefore, in the heavy article transport device 10, both rails 20 can be laid on the stairs 11 with a simple structure regardless of the inclination of the stairs 11. Further, since the gantry side fastening hole 53a and the rail side fastening hole 53b have a long hole shape, the position where the gantry side fastening hole 53a and the rail side fastening hole 53b communicate with each other can be finely adjusted. Therefore, in the heavy article conveyance device 10, the inclination angle of the rail 20 can be adjusted with high accuracy.

  Moreover, since the base side fastening hole 53a and the rail side fastening hole 53b are each simply a long hole shape, they are easily formed. Further, the top plate 33 of the carriage 30 is positioned horizontally using the telescopic device 40. Therefore, since the heavy article 12 is placed horizontally on the carriage 30, it can be safely transported without falling.

  The telescopic device 40 includes a horizontal portion side stay 41 and an inclined portion side stay 42, and can horizontally position the carriage horizontal portion 31 with a simple structure in which the overlapping portions 46 are fastened by bolts 47 and nuts 48. it can.
