Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall processing machine used on the inner wall surface of a ship that carries ore, coal, chips, and the like.

[0002]

[Prior Art]

 As disclosed in Japanese Utility Model Laid-Open No. 63-39492 and Japanese Utility Model Laid-Open No. 2-129455, there is a wall surface processing machine having a high-pressure water jet nozzle at the tip of the working machine system of a construction machine.

In this conventional wall processing machine, a water pump for supplying high-pressure water to the nozzle, a water tank, and the like are integrally mounted on a base machine of a construction machine.

Further, as the high-pressure water injection nozzle, only one direct injection nozzle is attached.

[0005]

[Problems to be solved by the device]

 The base machine in which the water tank and the like are integrated is large. Therefore, it is not easy to carry this base machine into a ship that carries chips and the like.

Further, in the case of removing chips adhering to shelves, ribs, pipes, stairs, etc. on the inner wall surface of a chip carrier, only the water stream intensively ejected from the conventional direct injection nozzle can remove the wall adhering chips. It cannot be removed efficiently. Wall deposits such as ores and coal that are heavy and easily eroded by water flow can be dropped by cutting them off with a direct jet, but wall-mounted chips are lighter than ores and coal and eroded by water flow. This is because it is difficult to get rid of it from the wall surface with only a direct jet.

The present invention has been made in view of the above points, and it is small and lightweight, can be easily carried into a ship, and can efficiently remove not only ore and coal but also wall deposits such as chips. It is intended to provide a wall processing machine.

[0008]

[Means for Solving the Problems]

 The invention according to claim 1 is a wall surface treatment machine in which a high-pressure water jet nozzle is provided at a tip of a working machine system of a construction machine, wherein high-pressure water is jetted to the high-pressure water jet nozzle with respect to a base machine of the construction machine. A high-pressure water pump unit for supply is installed separately, and this high-pressure water injection nozzle and high-pressure water pump unit are connected to each other by a water supply hose.

According to a second aspect of the present invention, as the high-pressure water injection nozzle of the first aspect, there is provided a wall surface treatment machine in which a direct injection nozzle capable of selectively supplying water by a switching valve and a widening injection nozzle are arranged in parallel.

A third aspect of the invention is a wall surface processing machine in which the high-pressure water pump unit according to the first aspect includes a hose reel that is rotated in the hose winding direction via a torque limiter.

[0011]

[Action]

 According to the first aspect of the present invention, the base machine is carried into the ship or the like, while the high-pressure water pump unit is installed on the deck of the ship, etc., and the working machine system of the construction machine is installed from this pump unit through the water supply hose. High-pressure water is supplied to the high-pressure water jet nozzle at the tip.

According to the second aspect of the invention, when the deposit on the wall surface is heavy like ore or coal and is easily corroded by water flow, the deposit on the wall surface is cut off by a direct jet flow. However, if the deposits on the wall are as light as chips and are not easily eroded by the water flow, operate the switching valve to switch the nozzle to be used from the direct injection nozzle to the expansion nozzle to remove water from a wide range of wall deposits. Make sure to wash it off by including it.

According to the third aspect of the present invention, when the base machine approaches the high-pressure water pump unit, the tension applied to the hose decreases and the torque limiter lowers the rotational force that can be transmitted. Rotate in the take-up direction and wind up the hose. When the base machine is stopped or when the base machine moves away from the high-pressure water pump unit, the tension applied to the hose increases and exceeds the torque that can be transmitted by the torque limiter. It spins in the opposite direction to feed the hose.

An engine 92, a water pump 94 that is driven by the engine 92 and sucks water from a water tank 93, and a hose reel 96 that receives high-pressure water via a pipe 95 that is drawn from the water pump 94. is set up.

Further, an oil tank 97 is provided between the engine 92 and the water tank 93, and an oil pump 98 driven by the engine 92 and a discharge from the oil pump 98 are provided on the oil tank 97. A hose reel operation valve 99 for controlling on / off of the hydraulic pressure is provided.

When the deposit on the wall is heavy like ore and coal and is easily eroded by the water flow, the deposit on the wall is cut off by the direct jet from the nozzle 16a for direct injection, and the deposit on the wall is dropped. , If the deposits on the wall are light like chips and are not easily eroded by the water flow, operate the switching valve 33 to switch the nozzle to be used from the direct injection nozzle 16a to the expansion nozzle 16b, and the fan-shaped jet By doing so, water can be contained in a wide range of wall deposits efficiently, and it can be washed away by the force of the jet flow.

In this way, the direct injection nozzle 16a and the expansion injection nozzle 16b are selected according to the attachment state of the tip or the like on the wall surface, and the vertical direction and the horizontal direction of the nozzle bending mechanism 32 are selected. The 180 degree swinging action and the adjustment of the water discharge pressure can be used to scrape off the chips, etc., that are heavily deposited on the ribs, pipes, shelves, stairs, etc. on the inner wall of the ship.

When the base machine 13a approaches the high-pressure water pump unit 17, the tension on the hose 19 decreases and falls below the rotational force that can be transmitted by the torque limiter 105, so the hose reel 96 moves in the hose winding direction.
