Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for suspending work machines, gondolas, scaffolding, etc. used for cleaning and painting ship hulls and building exteriors, etc. The purpose of this device is to obtain a trolley that can be stably moved over the wall of a large structure without being obstructed by handrails, etc., and to perform cleaning, painting, etc. work using a work machine suspended from the trolley. To provide a device for traversing on the wall surface of a large structure, which can be carried out reliably and safely.

Hereinafter, the present invention will be explained with reference to the illustrated embodiment. In the figure, 1 is a large structure such as a ship body or a building, and a projecting wall 3 is provided along a wall surface 4 on an upper part 2 as an anchor or the like.

The drawings show the hull as a large structure.

In this case, the projecting wall 3 may be a projecting wall that constitutes the Gatsuta Suido.

Support arms 5 projecting to the front side of the wall surface 4 are removably attached to the projecting wall 3 at intervals in the longitudinal direction with bolts or the like, and the tip of each support arm 5 is attached to the upper part 2 of the large structure. It is supported via a support member 6.

Reference numeral 7 denotes a mole rail, which is supported by the upper tip of the support arm 5 and is disposed above the wall surface 4 along the wall surface 4.

Reference numeral 8 denotes a bogie, and the bogie frame is formed by rigidly connecting an upper frame 8a and a lower frame 8b, both of which are box-shaped, in an inverted shape via a connecting frame 8c with a gangway.The upper frame projects inside the bogie frame. A support wheel 9 and a pair of left and right support wheels 10 are provided at the lower part of the lower frame 8a, and a support wheel 11 is provided at the inner side of the lower frame 8b.

Then, the trolley 8 engages the support wheels 9 with the mole lua, holds the mole lua between both sides with support wheels 10 in order to prevent it from slipping off, and supports the support wheels 11 on the wall surface 4. It is suspended and supported by the mole-lua via support wheels 9 in the state of being in rotation.

In order to adjust the upright posture of the truck 8 according to the distance between the projecting wall 3 and the wall surface 40, the support wheels 11 can be moved forward or backward toward the wall surface 4 by a mechanism described below.

That is, a bearing 12 whose bearing portion is a screw hole is fixed to the end of the bottom plate of the lower frame 8b, and a bearing-shaped slide member 13 facing the bearing 12 on the wall surface 4 side moves back and forth in the opposite direction. It is set up so that it can move freely.

A shaft 14 with a slide member 13 attached to the tip thereof is screwed into the bearing 12 through a threaded portion 14a provided thereon, and the lower frame 8 is threaded through the bearing 12 and the slide member 13.
Both ends are supported on the bottom plate of b.

Further, a bevel gear 15 is rotatably provided on the lower frame 8b.

The shaft 14 includes a spline portion 14b,
It is slidably fitted to the bevel gear 15 at the spline portion 14b.

Also, a shaft 16 is provided between the upper and lower frames 8a and sb.
is pivotally supported, and a handle 17 is provided at its upper end,
Also, a bevel gear 18 is provided at the lower end to mesh with the bevel gear 15, and the bundle 17 in the upper frame 8a rotates the shaft 16 to rotate the shaft 14 via a gear mechanism and rotate the shaft 14 through a screw mechanism and slide. The member 13 can be moved forward or backward toward the wall surface 4 via a guide mechanism.

A slide member 13 that moves forward and backward together with this shaft 14
Similarly, a movable bearing 19 is attached to the bottom plate of the lower frame 8b so as to be slid and guided.
0, and a buffer spring 21 is interposed between the slide member 13 and the movable bearing 19 with the connecting pin 20 as the center, and the support wheel 11 attached to the movable bearing 19 is connected to the movable bearing 19. It moves forward or backward toward the wall surface 4 via the guide mechanism.

In addition, a power supply box 22, a DC motor 23 with a speed reducer, and its control box 24 are provided on the bottom plate of the upper frame 8a so that the trolley 8 can be operated horizontally by driving the support wheels 9. A chain 27 is stretched between the chain gear 25 fixed to the output shaft of the support wheel 90 and the chain gear 26 fixed to the axle of one of the supporting wheels 90, and further between a pair of chain gears 28 fixed to the axles of both supporting wheels 90. A chain 29 is stretched.

The upper frame 8a is further provided with an airless paint pump 30 and a paint tank (not shown), and the lower frame 8b is equipped with wires for hanging the paint machine, power supply cables,
A hoisting drum 32 capable of uniformly winding paint hoses, air hoses, etc. 31 in a group manner, and an AC motor 33 with a reduction gear and a chain drive device 34 for driving the hoisting drum 32 are arranged.

In the above configuration, the own weight and load of the cart 8 are received on the upper surface of the mole Lua via the support wheels 9, and the overturning moment is received on the side surface of the mole Lua via the support wheels 10, and on the wall surface 4 via the support wheels 11. If the DC motor 23 is driven to rotate the support wheels 9 via the traverse drive mechanism (25 to 29), the trolley 8 will traverse in a stable state.

In this case, the mole lua is arranged in front of the wall surface 4, and the trolley 8, which is suspended and supported by the mole luer, is arranged above the front of the wall surface 4 in an inverted shape. Traversing can be done reliably without being hindered by handrails, etc.

The coating machine suspended from such a dolly 8 is stable, and the painting work on the wall surface 4 can be performed safely and reliably by its lifting and lowering operations and the lateral movement of the dolly 8.

Since the DC electric motor 23 for driving the running wheels 9 is still placed on the upper frame 8a of the trolley 8, the overturning moment of the trolley 8 can be reduced, and this combined with the fact that the lower frame 8b can be painted. It can be effectively used for arranging workers and equipment.

Moreover, since the protruding length of the supporting wheels 11 protruding from the lower frame 8b relative to the wall surface 4 can be adjusted, even if the positional force 5 of the protruding wall 3 changes due to the large structure 1, the cart 8
can be used.

Further, although a bevel gear is used as the shaft 140 rotational force type, it is not limited to this mechanism.

As described above, the present invention provides a large structure with a horizontal mole rail along the wall thereof, suspends an inverted-shaped bogie from the lower part of its upper frame to the mole rail so as to be able to run and drive it; The cart is supported by the wall so that it can run freely, the overturning moment of the cart is received by the mole rail and the wall, and the cart is configured to run across the wall of a large structure, and the support wheels for running on the wall are screwed onto the lower frame of the cart. The trolley can be moved in a stable state by being elastically supported by a buffer spring on a slide member attached to the slide member so as to be movable back and forth by a mechanism, and by adjusting the movement of the slide member so as to be freely adjustable back and forth toward the wall surface.

At this time, the rails can be easily installed without being obstructed by handrails or the like.

In addition, even if it is not possible to accurately lay the mole rail along the shadow line due to changes in the shadow line drawn by the wall of a large structure or the condition of the rail installation location, the running rail installed on the lower frame of the upside-down bogie can be used. By adjusting the support portion (support wheels 11) back and forth toward the wall, the cart can maintain a constant attitude and run stably along the shadow line drawn by the wall.

With such a trolley, suspension support for work machines, gondolas, scaffolding, etc. can be ensured and safely, and by adjusting the traveling support part provided on the lower frame of the trolley back and forth, it can be placed as close to the wall surface as possible, so it can be used for the desired work. can.
