Abstract

PROBLEM TO BE SOLVED: To move and install a workbench scaffolding regardless of the angle and unevenness of a slope by moving the workbench scaffolding longitudinally by the expanding action of a boom and laterally by a crawler truck. SOLUTION: An opening/closing workbench 1 is fixed to the tip of a boom 2 of a crawler truck 3 through an exclusive attachment 4. The opening/closing workbench 1 is horizontally set by a workbench scaffolding adjusting jack 5, and a working machine is placed thereon. The boom 2 is extended into a specified position, and the opening/closing workbench 1 is widened or narrowed according to the shape of a slope with the aid of a workbench scaffolding support jack 6 so as to adjust the distance to the slope. After a constructing direction is adjusted by a sliding rotary base 10, work is started. Lateral movement is performed by the crawler truck 3 in the state of the boom 2 being shortened to a minimum.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can easily and safely move a work platform scaffold for work on a slope or a high place with a work machine or a person on the slope regardless of the length or width of the work surface. It is a construction method that can also be used as a scaffold and construction scaffold for emergencies.

[0002]

2. Description of the Related Art Conventionally, when performing a slope work of an anchor boring work or a large diameter boring work, a work scaffold using a building scaffold material, a work scaffold using a single pipe pipe,
Working scaffolds using steel, working scaffolds made of single pipe or H-shaped steel and suspended by crane, stationary moving scaffolds where steel is placed vertically and horizontally on a slope, and works on crane boom tip An aerial work platform equipped with a scaffold, with a loading load of 1500 kg or less, an elevator that lifts and lowers luggage when moving. In some cases, a gondola is hung on a large crane and a person is riding in it to investigate.

[0003]

The prior art,
Is the most common method for performing slope work or high-altitude work. However, many skilled workers are required, the construction period and construction cost are enormous, and the high-place work rate is high, which is dangerous. Is used on slope work sites, but it is unstable and dangerous because of the suspended scaffolding, and is not legally recognized in practice.
Cannot be used if the slope has irregularities. The lifting machine of the aerial work platform has no permissible mechanical load such that the total weight is about 5000 kg, so the load capacity is small and it cannot be used. However, even in an emergency, it is dangerous because people are riding on a crane, so permission from the relevant authorities has been granted.

[0004]

Means for Solving the Problems A boom is attached to a crawler type cart, and an opening / closing work platform scaffold is attached to the tip of the boom by a dedicated attachment. The maximum allowable load is 1500 kg or more so that mechanical work such as anchor boring work and large-diameter boring work can be carried out. It is easy because it is a cart.
The present invention is an aerial work platform scaffold moving method having the above-described configuration.

[0005]

[Function] An open / close work platform for mechanical work on slopes or high places is attached to the tip of the boom of a crawler-type trolley with a dedicated attachment, and the work machine or a person moves vertically while the boom expands and contracts. It is easy to move laterally because it is a crawler type trolley, so it can be moved and installed regardless of the angle or unevenness of the slope. In addition, because it is a crawler-type trolley, it can move more easily than a wheel-type trolley even in places with little undulation and low ground strength on the ground and high difficulty.
Can be installed.

[0006]

Embodiments of the present invention will be described below. (B) Opening / closing worktable (1) with a dedicated attachment (4) at the tip of the boom (2) of the crawler-type trolley (3)
Is fixed. (B) Using the work platform scaffolding adjustment jacky (5), the openable work table (1) is set horizontally and the work machine is mounted. (C) Extend the boom (2) to a predetermined position, measure the work platform scaffolding support jackie (6), and open and close the work platform (1).
The distance to the slope is adjusted by widening or narrowing according to the shape of the slope, and the work is started after the construction direction is adjusted by the slide type turntable (10). (D) Lateral movement is performed by the crawler type trolley (3) in a state where the boom (2) is contracted to the minimum, and thereafter the same operation steps are repeated. The present invention is a construction method capable of easily moving and installing a work scaffold irrespective of a slope angle and unevenness by the above method.

[0007]

According to the present invention, there is no need for skilled workers to make a slope work platform or a work place at a high place as in the prior art, thus eliminating labor shortage, shortening the construction period, and saving costs, thereby creating a work platform. Work rate at high altitude is reduced, safety is increased, slope angle,
It can be installed regardless of unevenness. In recent years, landslides, landslides, etc. caused by earthquakes, typhoons, frost heaves, etc. have frequently occurred, and can be used immediately for investigation and construction at the time of an emergency disaster.

Claims (1)

[Claims] 1. A workbench that can move with a work machine or a person on a slope or a high place while mounting a boom on a crawler-type trolley. Or
An openable workbench is attached. The equipment of the work platform scaffold includes a slide-type turntable that adjusts the construction direction and the distance to the work position, a fall prevention handrail, a detachable small hoist, a work platform scaffold support jackie, and the shape of the slope work position. A device that can be expanded or narrowed can be installed. Since such equipment can be installed, the vertical movement of the work platform scaffold is performed by the expansion and contraction operation of the boom, and the horizontal movement is performed by the crawler type bogie, so that the work platform scaffold at a high place can be easily moved.
