Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a structure of a bucket mounted at the tip of a boom. Since it can take a posture such as fixing a part of the body closely, it can be done without leaning forward and the work posture can be done, and the tools and equipment used for working at high places in the bucket can be handy. The present invention relates to a bucket structure for an aerial work vehicle that can be taken out, used and stored.

[Conventional technology]

Generally, as shown in FIG. 3, an aerial work vehicle 1 is equipped with a bucket 4 and the like at the tip of a boom 3 which is erected and extendable by pivotally attaching a base end to a turntable 2 mounted on a chassis 1a. In reality, the worker M is riding on the bucket 4 to perform work at a high place.

However, the loading position of various equipment and various tools a (for example, large pipe wrench, hammer) used in the conventional bucket 4 is the floor portion 14 of the bucket 4 as shown in FIG. Small and lightweight equipment, tools b
(For example, a driver or pliers) is attached to the work waist belt B or the like carried by the worker M, picks up the floor portion 14 when working, and pulls out the work waist belt B each time. is the current situation.

[Problems to be solved by the device]

As described above, when there is no suitable space for placing various equipments, various tools a, etc. on the floor 14 in the bucket 4,
I had no choice but to bring the bucket 12, tool box 13, etc. into the narrow bucket 4, and I also used a dedicated waist belt B for work, but this waist belt B for work is relatively heavy and long. The fatigue of the worker M cannot be neglected in the work of time, and various heavy and bulky equipment that cannot be attached to the work waist belt B, various tools a, etc. are complicated to handle from the work box and the like. There are problems, and various equipment,
When the loading position of the various tools a and the like is on the floor 14 of the bucket 4, the worker has many problems in safety management such as breaking the work posture when taking the equipment and the various tools a and compelling extra movements. Since there is a problem and the cross-sectional shape of the bucket 4, especially the inner side surface 15 is formed as a vertical shape as shown in FIG. The waist, legs, knees, etc. are pressed against the inner surface 16 and the inner surface 15, and the legs are oriented and placed diagonally.The posture is unnatural and the center of gravity of the body tends to be outside the bucket. In terms of work, there was a problem of lack of promptness and safety.

[Means for Solving the Purpose and Problem of Invention]

The present invention has been made in view of the above problems,
The purpose is to stabilize the work posture of the worker when working in the bucket equipped at the tip of the boom of an aerial work vehicle, and also efficiently take out and store various tools and equipment used. In order to achieve the purpose, in an aerial work vehicle equipped with a bucket at the tip of a boom, in order to achieve the purpose, the bucket is composed of an inner case and an outer case. It has a heavy structure, and the vicinity of the upper edge of the inner case is projected toward the inside of the case by a predetermined width to form a bulging portion, and the lower portion of the bulging portion is curved toward the outer case to form a pocket portion. Then
The lower part of the inner case is brought closer to the outer case side so that the lower width of the inner case is wider than the upper width of the inner case.

[Action]

Since the configuration as described above is adopted, the worker's foot is placed in the depth space for the scaffold when working in the bucket, so that it is possible to directly face the bucket side wall and maintain the vertical posture on the bulging portion. Since it can take a posture that tightly fixes a part of the body such as the waist, it can perform work without leaning forward and leaning, and tools, equipment, parts, etc. are properly placed in the pocket provided on the inner circumference of the bucket. Since it can be placed and stored, workability is improved, work efficiency is improved, and fatigue due to an unnatural posture can be reduced, enabling safe work in high places.

[Embodiment] An embodiment of the bucket structure for an aerial work vehicle according to the present invention will be described in detail below with reference to Fig. 1 (a) and Figs. 2 to 3.

As described above, the aerial work vehicle 1 is configured by equipping the turntable 2 mounted on the chassis 1a with the base end pivotally erected, and provided with the bucket 4a at the tip of the boom 3 which is extensible and retractable. When working at a high place, the worker M rides on the bucket 4a and performs a predetermined work at a high place. The bucket 4a shown in FIG. 1 (a) has the bucket structure according to the present invention.
4a This was carried out on the entire inner wall of the inner surface. That is, the bucket 4a mounted on the tip of the boom 3 of the aerial work vehicle 1 has a double structure including an outer case 4b and an inner case 4c, and the sizes of the outer case 4b and the inner case 4c are shown in the same figure. As described above, the outer case 4b is formed large, and the inner case 4c, which is slightly smaller in size, is integrally lining-supported inside the outer case 4b by a soft resin having a high insulating property. Inner case 4c
The vicinity of the upper edge of the bucket 4a is inwardly projected by a predetermined width W to form a bulging portion 5, and the lower portion of the bulging portion 5 is curved toward the outer case 4b to form a pocket 6. The lower part of the pocket 6 is gradually widened toward the bucket floor 7.

Hereinafter, the operation of the bucket structure for an aerial work vehicle according to the present invention will be described based on the above configuration.

That is, the vicinity of the upper edge of the inner case 4c is protruded toward the inside of the bucket 4a by a predetermined width W to form a bulging portion 5, and a scaffolding depth space 8 is provided below the pocket 6. Therefore, since the operator's foot can be placed in the scaffolding depth space 8, it is possible to face the side surface of the bucket, and a part of the body such as the waist is brought into close contact with the vertical portion 9 of the bulging portion 5 while maintaining the vertical posture. Since it can take a fixed posture, the work posture can be performed without leaning forward, and the pocket 6 provided on the inner circumference of the bucket 4a is loaded in the bucket, for example, various tools such as valves, boosters, and insulators, equipment, Since the parts a, b, etc. can be appropriately arranged and stored, tools, equipment, parts a, can be placed inside or outside the bucket 4 as is conventionally done.
There is no need to hang a canvas (canvas) bucket 12 that holds b, etc., and a wide working space can be secured in the bucket 4b, and tools, equipment, parts a, b, etc. are accidentally dropped. There is no danger of causing it, work is good, work efficiency is improved, and fatigue due to an unnatural posture can be reduced.

Incidentally, FIG. 1 (b) relates to the present invention, and is an embodiment in which the pocket provided in the bucket is limited to a pair of opposed longitudinal side walls.

In each figure, the same parts are designated by the same reference numerals.

[Effect of device]

As described in detail above, the present invention has a structure in which an aerial work vehicle equipped with a bucket at the tip of a boom has a double structure consisting of an inner case and an outer case. The inside of the case is protruded by a predetermined width to form a bulge portion, and the lower portion of the bulge portion is curved toward the outer case side to form a pocket portion, and the lower side of the inner case approaches the outer case side. Since the lower width of the inner case is configured to be wider than the upper width of the inner case, the operator's foot is placed in the depth space for scaffolding when working in the bucket, so that the bucket side wall can be directly faced. Since it is possible to take a posture in which a part of the body such as the waist is tightly fixed to the bulging part while maintaining the vertical posture, the work posture can be performed without leaning forward, and further, it is provided on the inner circumference of the bucket. In your pocket A tool, equipment, improvement of appropriately arranged housing to workability good work efficiency Okeru parts like, equal various excellent effects attained together also reduce fatigue due to unnatural posture.
