Abstract

PURPOSE: To improve the efficiency of the removing work, by installing a grasping device which can exchange various attachments suitable for a scattered matter attached to the inner wall of the hold of a tanker, to the tip of an arm. CONSTITUTION: An inboard scratching device is grasped by operating the cylinder for grasping device of a grasping device to which the support pin 50 and the link support pin 51 of the inboard scratching device having a blasting device 60 are installed at the tip of the arm. When an air injection type inboard scratching device is selected and grasped, the attached scattered matter is scratched out by a wire brush 66 or a flexible spatula 68 installed to the tip of a scratching plate 67, and at the same time, the scattered matter is blasted out by a pressurized atmosphere by the first blasting driving device 60. And when a rotary inboard scratching device to rotate a blasting unit installing case is selected, the wire brush or a flexible spatula at the tip is reciprocated or rotated continuously by rotating a rotary circle, so as to cut down the scattered matter continuously. By such a way, various inboard scratching devices can be selected in a short time, and the scratching work mode can be converted.

The upper revolving structure 302 is provided with a hose reel 319 for winding the hose 321 used for supplying water from the water source to the water tank 304. The hydraulic excavator is constituted by a hydraulically operated blade 318 via an arm 341 on a lower traveling body 301 of the hydraulic excavator.

[0006]

However, in the powder raw material scraping device shown in FIG. 11 and the wall surface processing device shown in FIG. 12, only the jet water is used for scraping depending on the size, specific gravity and water content of the removed material. In some cases, the mode of action cannot be changed, and effective scraping work may not be performed. Then, although there are attachments A, B, and C dedicated to the wall surface treatment, hooks 332 thereof are hooked on a hook 329 on the working machine side, a hole 334 for connection and a hole 330 on the working machine side are aligned, and a pin is inserted. , Fixed. In this case, it takes a long time to insert the pin, and the pin may be scuffed after use, which makes it difficult to pull out the pin or damages the pin.

Further, in the powder raw material scraping device shown in FIG. 11, since the pressurizing pump 207 and the water pump 306 for the scraping spray water are installed on the carriage 209 and the upper swing body 302, the water spraying is performed. Nozzle 204, high pressure water jet nozzle 3
Since the distance to 56 is long, there is a problem that the capacity is insufficient in a small pump having a large piping resistance.

In the construction machine 200 with the powder raw material scraping device for the waste storage tank on the inner wall of the hold shown in FIG. 11, for example, the pressurizing pump 207 for injecting high-pressure water onto the truck 209 and the rear portion of the truck 209. Since the water tank 218 is additionally installed, the rear portion of the construction machine 200 becomes long, and the workability deteriorates in a narrow ship requiring a small turning radius, and the weight increases.

Further, in the wall processing machine shown in FIGS. 12 to 14, the thick pipes attached to the boom and the arm hinder the work, and the projections around the water supply and drain pipes provided along the ship wall are provided. Often interferes with things, deformation,
It is easily damaged. In addition, there is a movement limitation due to the connecting pipe or the hose. Further, since only the spatula 203 at the tip reciprocates in the left-right direction, the tip of the spatula 203 is far from the operator, is hard to see, and is a rigid body, which easily damages the ship wall. Further, since the spatula plate 203 does not tell the operator even if it interferes with the spatula plate 203, there is a problem that the surrounding projections such as the water supply / drainage pipes provided along the ship wall are damaged.

Further, in the case of a scraper having a strong adhesive force, it may not be possible to carry out an effective scraping work by a scraping motion of only vertical and horizontal movements.

The present invention has been made in view of the above problems and relates to an inboard scraping work vehicle suitable for a scrap attached to the inner wall of a storage tank hold, and in particular, it is attached to a concave portion such as a keel of a hold during a tip unloading work. To provide an inboard scraping work vehicle that facilitates effective replacement of attachments in the inboard ship scraping work used to drop chips left between reinforcing ribs of the hold wall to the bottom of the ship. With the goal.

In the in-board scraping work vehicle 1 configured to scrape off the debris attached to the inner wall of the storage tank hold, according to the type, size, specific gravity and water content of the debris attached to the inner wall of the storage tank hold. It is possible to select the inboard scraping device 35 provided with the small and lightweight blow-off driving devices 60 and 134 adapted to them. In addition, the gripping device cylinder 38 is operated by the gripping device 33 that attaches the support pin 50 and the link support pin 51 of the selected inboard scraping device 35 to the tip of the arm 32 and grips the inboard scraping device 35. Can be easily gripped.

In the inboard scraping work vehicle 1 in which the air jet type inboard scraping device 35A or 35B is selectively gripped, the storage tank hold by the wire brush 66 or the flexible spatula 68 attached to the tip of the scraping plate 67. The scraping material attached to the inner wall is scraped off and the first blow-off drive device 6
When the pressure is 0, the air is blown away in the pressurized atmosphere 61a. This pressurized atmosphere 61a is attached between the air blower 61 and the hydraulic motor 63 for driving the air blower inside the blow-off unit mounting case 54. Therefore, the air blower 61 is connected between the inlet of the atmosphere 61a and the air nozzle 65 of the outlet. Since the length of the pipeline is short and the air supply / exhaust resistance is small, the working capacity is exhibited even with the small air blower 61. Further, by using the first blow-off drive device 60 which can be made compact, the weight of the vehicle is reduced and the vehicle is compact. Because of this, it is possible to move freely within a narrow ship.

When the stored water prepared in the ship can be used by connecting it to the water supply pipe, a wire brush attached to the tip of the scraping plate 67 by selectively gripping the water jet type inboard scraping device 35E or 35F. 66 or a flexible spatula 68 scrapes off the debris attached to the inner wall of the storage tank hold, and the second blow-off drive device 134 blows away the pressurized distribution water jetted from the water jet nozzle 138. . This pressurized water is supplied to the water pump 1 inside the blow-off pump unit mounting case 130.
Since 33 and the hydraulic motor 63 for driving the water pump are attached, the pipe length between the water suction tube 120 and the water injection nozzle 138 at the outlet is shortened, so that the supply / discharge resistance is small. As a result, even the small pump 133 can exert its working capacity. As a result, the weight of the vehicle is reduced by using the second blow-off drive device 134 that can be downsized,
It is compact. Because of this, it is possible to move freely within a narrow ship.

In addition, the inboard scraping work vehicle 1 is small and lightweight, and has a long reach from the power tilt device 52 capable of swing-tilting in the left-right direction to the tip of the blow-off unit mounting case 54. Swing tilt operation can be performed greatly. As a result, the working range of the scraping plate 67 is widened, and while avoiding obstacles such as outfitting piping, the deposits on the corners of the bulkhead bulkhead can be scraped off in the left-right direction with good workability even in a narrow ship.

A swivel inboard scraping device 35C for swiveling the blow-off unit mounting case 54,
The inboard scraping work vehicle 1 that selectively grips 35D, 35G or 35H turns the turning circle 115 to reciprocate the wire brush 66 at the tip or the flexible spatula 68 or continuously turn the posture. Since it is constituted by means, the blow-off unit mounting case 54 can be swung to continuously shave off the deposits on the corners of the bulkhead partition by the rotating wire brush 66 or flexible spatula 68.
