Problems solved by technology

[0010] However, in the swivel arm type gondola device constructed before as mentioned above, since the trolley 93 and the counterweight 98 move in the opposite direction, and the amount of movement is also different corresponding to the weight ratio of the two, it is necessary to separate them. Equipped with the driving mechanism of the trolley 93 and the driving mechanism of the counterweight 98, and it is necessary to make the driving mechanisms of the two operate synchronously, there are problems that the driving mechanism is complicated and the control is troublesome.

Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings.

[0035] Fig. 1 is a side view of a gondola device to which a configuration example of a suspension trolley moving mechanism in the gondola device according to the present invention is applied, and Fig. 2 is a plan view thereof.

[0036] The illustrated gondola device 1 is disposed on a rail 2A laid on the roof of a building 2, and is rotatably supported on a support trolley 11 on a boom 12 as a boom member, and is movable along the boom 12. A trolley 13 as a suspension trolley is arranged on the ground, and a hanging basket box 15 as a workbench is suspended and supported up and down by a sling 14 as a sling member hanging from the trolley 13 . In addition, also have: travel drive mechanism 16 that travels along track 2A, drive the rotation drive mechanism 17 that cantilever 12 rotates, drive the hoisting drive mechanism 18 of hanging basket box 15 lifting, and drive trolley 13...

Abstract

A suspended carriage moving mechanism in a gondola device capable of interlocking a counterweight with a suspended carriage different in the moving direction and quantity with a simple constitution is provided. In this gondola device 1, a trolley 13 and the counterweight 19 are connected by an interlocking moving mechanism having a rear pulley mechanism 31, a front pulley mechanism 32 and an endless winder 33. The rear pulley mechanism 31 is constituted so that a driving wire 31W having the base end fixed to the rear end side of a boom 12 is joined at the tip to the trolley by winding and reversing a rear moving pulley 31M arranged on the counterweight and winding and reversing a rear fixed pulley 31F arranged on the rear end side of the boom. The front pulley mechanism is constituted so that a connecting wire 32W having the base end fixed to the tip side of the boom is joined at the tip to the trolley by winding and reversing a front moving pulley 32M arranged on the counterweight and winding and reversing a front fixed pulley 32F arranged on the tip side of the boom.

Description

technical field [0001] The present invention relates to a suspension trolley that is movably provided along the boom component on a boom component rotatably supported by a support column component, and suspended vertically by a suspension rope component hanging from the suspension trolley. A mechanism that moves a suspended trolley in a gondola device that supports a workbench. Background technique [0002] When cleaning windows of high-rise buildings or performing maintenance inspections on exterior walls, etc., a gondola device that supports a workbench is used in a manner that can be lifted and lowered by a suspension rope hanging from the upper part of the building. [0003] As such a gondola apparatus, there exists the technique disclosed by patent document 1, for example. It is formed by installing a trolley equipped with a coiling mechanism and a tilting and rotating boom on the roof of a building movably along the guide rails laid along the outer wall. The hanging ...
