Description

  The present invention relates to a dust remover, and more particularly to a dust remover for removing dust that floats or accumulates in water such as dams and rivers.

  In the vicinity of water intakes such as dams and rivers, there are a large amount of garbage such as dust and driftwood that floats and accumulates from the upstream. These garbage close the intake and prevent the intake, and if they are released downstream, they block the waterways for industrial and domestic water, damage the bridges, and also adversely affect the fishery near the river mouth. There is a risk of giving. For this reason, it is necessary to remove these garbage regularly.

Conventionally, as described in Patent Document 1, such a dust removal operation uses a dust remover provided near a water intake of a dam or a river. However, the position of the water surface near the intake varies greatly depending on the season, climate, etc., so these dust removers require lifting means, and wire ropes are particularly used for huge structures such as dams. ing. When raising and lowering a grab bucket, rake, or the like, which is a dust gripping means, using a wire rope, it is difficult to position the dust gripping means at a target position, making it difficult to perform an efficient dust removal operation. Moreover, even when the dust remover is movable along the dust removal screen (bar screen), only the dust in the vicinity of the dust removal screen can be removed, and the dust accumulated in the water is almost difficult to remove. . Moreover, in a huge structure such as a dam, dust removal in a wide range is necessary, and the structure of the dust remover itself is increased in size, and the work efficiency is poor for high cost.

In addition, the split assembly type work platform ship described in Patent Document 2 can easily join a plurality of floating body units by connecting pins, so that the workability at the time of assembly / disassembly is remarkably improved. .

However, when using the above-mentioned divided assembly type work platform ship as a dust remover on a river or lake, it is necessary to install heavy machinery such as a crane, and it is sufficient to simply join the floating unit with a connecting pin. The mechanical strength could not be secured, and there was a risk that the trolley could be disassembled due to local loads.
In addition, in order to strengthen the coupling between the floating body units, it may be possible to increase the number of connecting parts between the floating body units or to use a lot of welding, etc., but in these cases, the assembly and disassembly work becomes complicated, In the latter case, not only the on-site work becomes large-scale, but also harmful effects such as difficulty in water work and disassembly work occur.

  The problem to be solved by the present invention is to provide a dust remover that solves the above-described problems, is easy to assemble and disassemble, and can stably hold a crane. The purpose is to provide a dust remover that improves the work efficiency of cranes on a trolley and has a low impact on the natural environment.

Hereinafter, the dust remover according to the present invention will be described with reference to examples.
The dust remover of the present invention includes a plurality of floating units that are arranged and fixed over the top surfaces of the plurality of floating units in an assembly type carrier that is connected to a plurality of floating units, and a dust remover that has a swivel crane installed on the assembly type carrier. A reinforcing beam and the crane are installed on the reinforcing beam.

(Floating unit)
As a configuration of the floating unit, the floating unit disclosed in Patent Document 2 can be used. Specifically, as shown in FIG. 3 (a), the floating body unit 1 includes a float body 30 of a hollow body and an upper surface top plate 31 attached to the top of the float section and having an aspect ratio of 2: 1. Composed. The aspect ratio of the top surface top plate 31 is not limited to a ratio of 2 to 1 as long as the vertical length is designed to be an integral multiple of the horizontal length.

It is possible to provide a weight portion at the lower part of the floating body unit 1 as shown in Patent Document 2, but as will be described later, two or more floating body units are fixed with a connecting pin, in particular, the length of the floating body unit 1 There is no possibility that the floating unit rotates on the water and is turned sideways or in the opposite direction by simply fixing the sides facing each other, so that the weight portion can be omitted as shown in FIG.
In addition, when adjusting the draft of the floating unit, a predetermined amount of gravel, water, etc. is introduced from an openable / closable opening (not shown) provided on the top plate so that the draft of the floating unit can be adjusted. Has been.

On the side surface of the floating body unit, at least two pairs of upper and lower connection plates 33 and 32 are arranged as engaging portions for connecting the floating body unit, and the number of connection plate pairs provided on the long side surface is as follows. It is an integral multiple of the pair of connecting plates provided on the short side.
Openings are formed in the connection plates 33 and 32 so that the connection pins 40 can be inserted as shown in FIG. In particular, in order to facilitate the insertion of the connecting pin 40, the opening of the connecting plate 33 is formed larger than the opening of the connecting plate 32, and the connecting pin is correspondingly thicker on the upper side than the lower side. . (In addition, code | symbol 30'-33 'shows the component of another floating body unit.)
In addition, an elliptical collar is formed on the upper end portion of the connecting pin 40 to prevent the connecting pin from falling off, and since the handling method thereof is described in detail in Patent Document 2, it is omitted here. .

  As a connection method of the floating body units 1, a plurality of floating body units 1 are floated on the water, and the floating body units 1 are sequentially fixed by the connection pins 40 so as to have a desired shape. As described above, the connection work of the floating unit used in the present invention can be performed on the water, and the dust remover according to the present invention can be used even in a narrow area where it is difficult to assemble the entire carrier on the ground. A trolley can be assembled.

(Assembly type carrier)
The shape of the trolley can be any shape, such as a square or a rectangle, but considering the installation of a swivel crane, the garbage can be shaped like an H-shape in FIG. 1 or a U-shape in FIG. The floatable unit 1 is preferably connected to the assembling-type carriage so as to form a U-shaped opening.

  In order to install a heavy machine such as a swivel crane on a trolley, a trolley fixed only by a connecting pin 40 lacks mechanical strength. Therefore, in the dust remover of the present invention, the reinforcing beam is arranged and fixed over the upper surfaces of the plurality of floating body units, and a crane is installed on the reinforcing beam. In this way, the load applied to the joint between the plurality of floating body units is reduced by configuring the crane weight and the load accompanying the crane work to be distributed to each floating body unit through the reinforcing beam. By supporting the weight of the crane with the entire floating body unit constituting the carriage, the position of the crane can be stably maintained even on the water surface. In addition, when fixing a crane, it cannot be overemphasized that fixing to a floating body unit can be used together in addition to fixing to the above-mentioned reinforcement beam.

Regarding the number and arrangement of the reinforcing beams, it is preferable that the swing crane is stably held and the weight of the crane and the load related to the operation by the crane are dispersed as much as possible in the entire floating body unit.
For example, as shown in FIG. 1 (b), two reinforcing beams 2 are fixed to each floating body unit 1 with respect to an H-shaped trolley connected to the floating body unit 1 by bolt connecting means such as bolts and nuts. . Next, a spacer beam 3 having the same height as that of the reinforcing beam 2 is disposed and fixed for each required floating body unit, and the reinforcing beam 4 and the reinforcing beam 4 are bridged so as to bridge the reinforcing beam 2 and the beam 3. Fix to beam 3.

Since the swivel crane is arranged and fixed on the reinforcing beam 2 at the position of the dotted circle in FIG. 1B, it is important to stabilize the positional relationship between the plurality of reinforcing beams 2. FIG. It is more preferable to arrange the plurality of reinforcing beams 2 on the same floating body unit as shown in FIG.
The material of the reinforcing beams 2 and 4 and the spacer beam 3 is preferably a material having high strength against twisting and bending, such as H-shaped steel.

(Swivel crane)
As the revolving crane 10 installed on the assembly-type trolley, an articulated crane having a support portion 11, a first arm 13, and a second arm 14 is preferable as shown in FIG. The support portion 11 includes a fixed portion that fixes the crane to the reinforcing beam 2 and a turning portion that can rotate 360 degrees with respect to the fixed portion while supporting the first arm.
In addition, an operator chair 12 is fixed to the turning portion, and the operator rotates around the fixed portion as the crane turns.

An auxiliary boom 15 that can be expanded and contracted is attached to the second arm 14. In order to increase the length of the auxiliary boom 15, it is also possible to remove the connecting member 21 at the tip of the auxiliary boom 15 and fix the auxiliary boom for extension separately.
The connecting member 21 is attached with a full turning rotator 16 as a turning jig, and is further connected to an attachment boom 17 and a grapple 18 as a gripping means for gripping dust.

  In order to remove the dust in the water or the bottom of the water, it is necessary for the grapple 18 to move deeply into the water. For this purpose, the attachment boom 17 is indispensable as shown in FIG. However, when removing wood or the like floating on the water, it is preferable to remove the attachment boom 17 and connect the grapple directly to the rotator 16.

  When the grapple 18 is located underwater, the grapple is out of the operator's field of view, and therefore the opening and closing direction of the grapple claw cannot be confirmed. For this reason, from the positional relationship between the mounting direction of the rotator 16 with respect to the attachment boom 17 and the mounting direction of the grapple 18 with respect to the attachment boom 17, for example, the positions of the mounting pins 19 and 20 for fixing the two or the attachment boom 17. It is possible to specify the opening and closing direction of the grapple claw using the provided mark or the like as a mark.

The rotation operation of the turning portion in the support portion 11 described above, the rotation operation of each arm, the expansion and contraction operation of the auxiliary boom 15, the rotation operation of the rotator 16, and the opening and closing operation of the grapple 18 are all performed by hydraulic operation. Each operating mechanism is supplied with hydraulic oil via a hydraulic hose from a generator hydraulic unit separately installed on the carriage.
Further, when connecting the auxiliary boom or the attachment boom 17, it is necessary to change the length of the hydraulic hose. For example, these operations can be performed by using a hydraulic hose having a quick joint joint. It becomes possible to carry out efficiently.

  The hydraulic fluid used for swiveling cranes, swiveling jigs, or grapples and the grease for moving parts use highly biodegradable materials, so even if hydraulic fluid and grease are released into water, It is possible to suppress the influence exerted to the minimum. For example, fatty acid ester synthetic oil (product name: Highland Zinen 46, manufactured by Shin Nippon Oil Co., Ltd.) is used as the hydraulic oil having biodegradability, and biodegradable grease (product name: Bionock) using vegetable oil as the grease. Zinen (manufactured by Shin Nippon Oil Co., Ltd.) can be suitably used.

(Dust storage container)
In order to transport the dust collected by the dust remover from the water to the ground, it is possible to move the dust directly with a swivel crane installed on an assembly-type carrier, but the dust held by the grapple is temporarily It is also possible to provide a storage container 6 (see FIG. 1 (b)) that can be stored and transported together. The storage container 6 is preferably a container having an opening on the upper surface, and an opening / closing door is installed on the side of the container and the container is tilted so that dust contained in the container can be discharged.
The storage container 6 can be detachably attached to a floating body in which two floating body units 1 are fixedly arranged by fixing means 7 (the fixing means can be arranged not only on the side surface of the floating body unit but also on the bottom surface side). It is possible to arrange in
Further, a drain hole is provided in the bottom of the storage container 6 so that when the storage container 6 is lifted by a crane or the like placed on the ground, excess water can be discharged.

(Observation means)
Since the dust remover of the present invention is provided with observation means for observing the underwater or the bottom of the water, the position and shape of the dust can be discriminated using the observation means even in underwater work, Since the position can be set appropriately, the efficiency of dust removal work can be further improved.
As the observation means, an underwater camera or sonar that detects visible light or infrared light can be used. As the installation method of the underwater camera, there are a method of fixing in the middle of the attachment boom, a method of fixing to a part of the trolley such as sonar, and a method of hanging underwater from the trolley.

  The dust remover according to the present invention is not limited to the above-described one, and for example, a technique known in the technical field can be applied, for example, an outboard motor is attached to a trolley, and an assembly-type trolley itself is self-propelled. Needless to say.

  As described above, according to the dust remover of the present invention, it is possible to provide a dust remover that is easy to assemble and disassemble, and that can stably hold a crane. It is possible to improve the working efficiency of the crane and to provide a dust remover with a low load on the natural environment.
