Description

[Detailed description of the invention] The present application relates to a suspension trolley for a working gondola that is capable of suspending a working gondola that moves up and down along the outer wall surface of a structure via a hanging rope, and in particular, It can be applied to work gondolas of different dimensions, and it is also possible to efficiently work on the outer wall surface of the structure at the corner of the structure.The embodiment of the present application will be described in detail below with reference to the drawings. 2, 2' and a pair of left and right vertical rods 3, 3', drive wheels 5, 5 are mounted at the left and right corners of the front lower surface of the rectangular frame 4, and driven wheels 5, 5 are mounted at the middle of the rear lower surface for switching the running direction. It is a moving truck equipped with wheels 6, and the driving wheels 5, 5 are mounted on a frame 4.
The drive wheels 5, 5 are driven by a motor 8 mounted on the front lower surface of the frame 4. They are interlocked and connected by a shaft 9. Further, the driven wheel 6 is supported by a bearing member 11 on a mounting shaft 10 rotatably installed vertically on the rear lower surface of the frame 4, and an operating handle 12 for changing direction is mounted on the mounting shaft 10. It is being Therefore, this movable trolley 1 moves freely on the roof of the structure A by driving the motor 8 and operating the operating handle 12. Reference numerals 13, 13 denote vertically extending shaft cylinders whose lower ends are pivotally mounted 14 to the left and right positions of the front part of the frame body 4 so as to be tiltable in the front and rear directions. A fixture 17 is provided for removably connecting the other end of the stay 16 rotatably supported via a fixture 15 on the frame 4 with a pin or the like, and inside the lower ends of the shaft tubes 13, 13. There is a locking rod 18
are horizontally suspended in the diametrical direction. Reference numerals 19 and 19 denote support tubes whose lower parts fit into the shaft tubes 13 and 13, and a locking groove 20 that engages with the locking rod 18 is provided at the lower end of the support tubes 19 and 19. Locking groove 2
0 and the locking rod 18, the shaft cylinder 1
Support tubes 19, 19 for 3, 13 are held unrotatable. 21 is a bearing ring fixed to the inner peripheral surface of the upper end of each of the support cylinders 19, 19, and 22 is a rotating shaft 2 rotatably fitted to the bearing ring 21 at the lower end.
2' and a hanging support made of a long tube with a large curve at the top, and a hanging tool 23 at the tip.
A self-elevating work gondola B is suspended from the pair of left and right suspension columns 22, 22 via the hanging device 23 so as to be parallel to the outer wall surface of the structure A using a hanging rope 24. It will be done. 25 is the shaft cylinder 13
It is a rotation position setting mechanism for setting the rotation position of the hanging column 22 relative to the shaft cylinder 13, and has a fixing part 27 that projects horizontally from the outer circumference of the upper end of the shaft cylinder 13 and has an engagement hole 26.
An adjustment plate 29 is attached to the outer periphery of the lower end of the hanging column 22 and has a plurality of engagement holes 28, 28, . and a lock pin 31 that engages with the engagement hole 26 and the engagement holes 28, 28, . . . Reference numeral 32 denotes a balance weight installed at the rear of the movable cart 1.

As shown in FIGS. 1, 2 and 3, the work gondola B is connected to the hanging tool 23 via the hanging rope 24.
When the gondola B is suspended and the self-propelled winder 23 attached to the gondola is driven, the working gondola B moves up and down along the outer wall surface of the structure A. In addition, as shown in Fig. 3, when suspending work gondolas B with different widths from the suspension supports 22, 22, or when moving work gondolas B horizontally in the left-right direction, for example, in order to shift the work gondolas B to a corner of structure A. When doing so, the gondola B is lowered to the ground, the suspension rope 24 is loosened in this state, and the rotation position of the suspension strut 22 relative to the shaft tube 13 is adjusted by the rotation position setting mechanism 25, and the gondola B is also lowered. After being moved on the ground, the gondola B is raised again. After the work on the outer wall by the work gondola B is completed, the gondola B is raised to a height above the parapet part A' of the structure A, and in this state, the mobile cart 1 is moved on the roof of the structure A. This allows the work gondola B to be pulled onto the roof.

Note that when sequentially connecting or removing the support tube 19 and the long suspension column 22 from the shaft tube 13, the stay 16 and the shaft tube 13 are uncoupled and the stay 16 and the shaft tube 13 are tilted. In this state, the support cylinder 19 and the hanging strut 22 are connected to or removed from the shaft cylinder 13.

As described above, according to the present application, the directions of the pair of left and right hanging struts can be changed independently.
It is highly versatile as it can be applied to work gondolas with different width dimensions, and the work gondola can also be raised and lowered while being deviated left and right from the front position of the moving trolley, making it particularly easy to move around the corners of structures. It has the advantage of being convenient when working on exterior walls.
