きいものがあつた。 Conventional bucket carts for aerial work vehicles are mostly made of glass fiber reinforced plastic (FRP) and have a flange on the top end, making them lightweight and relatively strong and with excellent insulation performance. However, in reality, energized points such as pinholes often appear over time, and even though strict precautions are taken during work, concrete poles, wooden pillars, houses, etc. The collision not only caused damage to houses and other objects, but also caused damage to the bucket itself, often resulting in a significant drop in insulation performance. Incidentally, in accordance with the Safety and Health Regulations, buckets are subject to periodic withstand voltage tests every six months to ensure good maintenance, but buckets are forced to be replaced during these periodic inspections. There have been a large number of cases, and there has been a strong desire among those skilled in the art for a bucket bag that is not only unfavorable from an economic standpoint, but also has even better safety.

る。 Therefore, the purpose of this invention was to solve all of the problems mentioned above, by providing even better insulation and electrical resistance, eliminating the need for replacement at regular inspections, and significantly extending the service life. , provides a bucket tote for aerial work vehicles that is extremely safe and economical, and is characterized by a cushioning material with grooves that corresponds to the shape from the flange to the upper part of the wall. Molded from an insulating and electrically resistant rubber material, this molded cushioning material is fitted continuously or discontinuously over almost the entire circumference from the flange of the bucket to the upper part of the wall, and the lower outer periphery of the wall. A cushioning material, also made of insulating and electrically resistant rubber material, is fixed around the entire circumference.

ツト１のフランジ部３から壁部上部５ａにかけて
ほぼ全周に渡り連続状に嵌着している。 Specific embodiments will be described below with reference to the drawings. 1 is a bucket for an aerial work vehicle installed at the tip of a boom 2 that bends and extends; The material used is glass fiber reinforced plastic (FRP), which has excellent insulation performance. Further, as shown in FIGS. 2 and 3, 4 is a molded cushioning material made of an insulating and electrically resistant rubber material with a groove 4a corresponding to the shape extending from the flange portion 3 to the upper wall portion 5a. It is fitted continuously over almost the entire circumference from the flange portion 3 of the bucket 1 to the upper wall portion 5a.
なお、当該成形緩衝材４は、バケツト１とブー

る。 It should be noted that the molded cushioning material 4 may be fitted discontinuously depending on the mounting position of the bucket 1 and the boom 2, or only in the minimum necessary range, and from the viewpoint of suppressing weight increase as much as possible. It will be done.
またこの実施例では特に、図示のごとく当該成

が最も好ましい。 Moreover, in this embodiment, as shown in the figure, the inner surface abutting part 4b of the molded cushioning material 4 is made longer than the outer surface abutting part 4c, so that the molded cushioning material 4 can be easily fitted once it has been fitted. It is formed so as not to separate from the flange portion 3 and the wall upper portion 5a. Of course, it is possible to use the inner surface abutting portion 4b and the outer surface abutting portion 4c with the same size or with the outer surface abutting portion 4c being longer, but the detachment direction of the fitted molded cushioning material 4 may be Considering that the direction is from the inner surface of the upper wall portion 5a to the upper surface of the flange portion 3, the above-mentioned formation is most preferable in order to sufficiently prevent separation.

トで締着して固着させる方法も考えられる。 Numeral 6 denotes a cushioning material molded from a dielectric and electrically resistant rubber material like the molded cushioning material 4, and is fixed to the entire lower outer periphery of the wall portion 5 with an electrically dielectric and electrically resistant adhesive. In addition to this embodiment, as a fixing means, for example, the overlapping or abutting ends of the cushioning material 6 may be fastened with bolts and nuts, without using an adhesive having electrical insulation properties, or using it as an auxiliary. Another possible method is to fix it.

６は一応極めて容易に離脱しないように固着して
はいるが、万一の場合も考慮して足をかけること
が不可能な形状としたものである。 Furthermore, the cushioning material 6 according to this embodiment has a roughly chevron-shaped cross-sectional shape, especially in the thickness direction,
This prevents workers from stepping on their feet unnecessarily when going in and out of the bucket. That is, if the fixed position of the cushioning material 6 is a convenient position for the worker to enter and exit from the bucket, the worker will often consciously or unconsciously step on the bucket. As shown, the cushioning material 6 is fixed so that it will not come off very easily, but it is shaped so that it is impossible to put your foot on it in case of an emergency.
なお６ａは緩衝面であり、前記成形緩衝材４の
フランジ部対応周側面とともに主に被衝突物等に
直接当接するように設けられた接触面である。 Note that 6a is a buffer surface, which is a contact surface that is provided so as to come into direct contact mainly with the object to be collided with the peripheral side surface corresponding to the flange portion of the molded buffer material 4.
また、第５図は、緩衝面６ａを有し、かつ作業

を取換えればよいものである。 By the way, when this type of bucket with the above-mentioned configuration is used by disposing it at the tip of the boom 2, the molded cushioning material 4 and the cushioning material 6 made of insulating and electrically resistant rubber material are provided above and below the bucket.
However, instead of the conventional bucket bag body, it directly collides with or comes into contact with the object to be collided with, and the impact of the collision or contact on the bag bag body is significantly reduced. In addition, due to the deterioration of the rubber material due to long-term use, it may be necessary to replace the molded cushioning material 4 and the cushioning material 6, but in that case, only the molded cushioning material 4 etc. should be replaced without replacing the bag bag itself. All you have to do is replace it.

material, has a flange part at the upper end, and a cushioning material with grooves corresponding to the shape from the flange part to the upper part of the wall part is molded from an insulating and electrically resistant rubber material,
This molded cushioning material is fitted in a continuous or discontinuous manner over almost the entire circumference from the flange of the bucket to the upper part of the wall, and the same insulating and electrically resistant rubber is fitted over the entire lower outer periphery of the wall. By fixing the cushioning material molded from the material, the insulation and electric strength performance is further improved compared to the conventional molded cushioning material and cushioning material.Moreover, due to its excellent cushioning properties, it is possible to avoid accidental damage to concrete poles etc. during work. Even if it collides with a concrete pole, it will not cause damage to the concrete pole, etc.
There is no longer a decrease in dielectric strength of the bucket itself. Therefore, it has been possible to eliminate the need to replace the entire bucket, which was conventionally required for regular inspections every six months, and to provide a bucket that has excellent durability and high safety. be. Furthermore, when replacing the bag after many years of use, it is possible to simply replace the molded cushioning material and the cushioning material, which is much more economical than in the past, where the bag itself had to be replaced. It is.
