Description

[Detailed description of the invention] The present application proposes a work gondola suspension device that is capable of suspending a work gondola that ascends and descends along the outer wall surface of a structure via a hanging rope. As a hanging means, a running rail was laid along the roof parapet, and a trolley consisting of two hanging supports was placed on the running rail so that it could run.

However, there are cases where it is not possible to run the trolley by laying running rails due to the structure of the roof. , by fixing this, 2
A work gondola was suspended from a book suspension post.

However, according to this configuration, since the socket member is vertical, it is troublesome to insert or remove the long suspension support from the socket member, and it is difficult to fix the suspension support to the shaft cylinder. Therefore, there was an inconvenience in use that the direction could not be changed.

Therefore, the present invention improves the defects of the conventional one by providing the support with a means for arbitrarily setting the direction of the support, and by attaching the socket member for receiving the lower part of the support to the parapet so as to be able to rise and fall freely. The embodiment of the present application will be described in detail below with reference to the drawings. Reference numeral 1 denotes a large number of socket members arranged at predetermined intervals along the inner surface of the parapet A' of the structure A;
The socket member 1 is a channel member having an inward U-shaped cross section that is fixed to the inner surface of the parapet A' by bolts. A locking hole 2 is provided at the upper end of the channel member, and a bearing fitting 3 is provided at the lower end. The lower end portion is pivotally connected to the body 4 and the bearing tool 3 so as to be able to rise and fall freely in the front and rear direction,
It consists of a shaft tube 7 with a bottom extending vertically and having a connecting tool 6 removably connected to the locking hole 2 with a connecting piece 5 such as a pin at the upper end, and inside the lower end of the shaft tube 7. In this case, the locking rod 8 is suspended in the diametrical direction. Reference numeral 9 denotes a support tube whose lower part fits into the shaft tube 7, and a locking groove 10 that engages with the locking rod 8 is provided at the lower end of the support tube 9. The support cylinder 8 is held unrotatably with respect to the shaft cylinder 7 by engagement with the locking rod 8. 11 is a bearing ring fixed to the inner circumferential surface of the upper end of the support cylinder 9; 12 is a long shaft having a rotating shaft 13 rotatably supported by the bearing ring 11 at the lower end and having a large curved upper part; It is a hanging support made of a pipe and has a hanging tool 14 at its tip, and a hanging rope 15 of a self-elevating work gondola B is suspended through the hanging tool 14. Reference numeral 16 denotes a rotation position setting mechanism for adjusting the rotation position of the suspension strut 12 with respect to the shaft tube 7, which includes a fixing piece 18 that projects horizontally from the outer periphery of the upper end of the support tube 9 and has an engagement hole 17 bored therein. , an adjustment plate 20 that is attached to the outer periphery of the lower end of the hanging column 12 and has a plurality of engagement holes 19, 19, . a handle 20 having a handle 20 and the engagement hole 17
and a lock pin 22 that engages with the selected engagement hole 19.

However, the long hanging support 12 is parapetted.
When installing it upright on the inner peripheral surface of A', first remove the connecting piece 5 to release the connection of the shaft cylinder 7 to the mounting body 4, and then lower the shaft cylinder 7 backward as shown by the imaginary line in Figure 2. In this state, attach the support tube 9 to the shaft tube 7 and lock the locking rod 8.
Then, the rotating shaft 13 is supported on the bearing ring 11 of the support tube 9, and then the hanging strut 12 is erected together with the support tube 9 and the shaft tube 7, and the connection is made again. The shaft tube 7 is connected to the connector 6 via the piece 5. In this way, the hanging struts 12, 12 are respectively erected on the pair of adjacent socket members 1, 1 on the inner peripheral surface of the parapet, and the hanging ropes 15, 15 are connected to the respective hanging tools 14, 14. The work gondola B is suspended from the
When the self-propelled winder 23 attached to the work gondola B is driven in this state, the work gondola B moves up and down parallel to the outer wall surface of the structure A. Further, as shown in FIG. 5, when suspending work gondolas B with different widths from the suspension supports 12, 12, or when moving work gondolas B to one side, for example, to a corner of structure A, the work gondolas B are moved horizontally in the left and right direction. When doing so, the gondola B is lowered to the ground, the suspension rope 15 is loosened in this state, and the rotation position of the suspension strut 12 relative to the barrel hole 17 is adjusted by the rotation position setting mechanism 16, and the gondola B is rise again.

As described above, according to the present application, since the socket member is equipped with a shaft cylinder that can be raised and lowered, a long suspension support can be inserted and removed with the shaft cylinder lying down, and the suspension support can be inserted and removed. It is convenient for replacement work, and
Since it is equipped with a mechanism to set the direction of the hanging strut, it can be applied to work gondolas with different width dimensions, and the work gondola can be raised and lowered while being offset from the front position to the left and right with respect to the outer wall surface. It has the advantage of being highly versatile and capable of effectively working on the outer walls of the corners of structures.
