Description

  The present invention relates to an assembly-type trolley formed by connecting a large number of floaters.

  When constructing the retaining wall or bridge of an existing dam, a base boat that will serve as a scaffold will be levitated above the water, and heavy machinery will be installed on the base boat. This trolley is levitated above the water only when construction is completed, and is removed when the construction is completed. Therefore, the trolley is divided and formed as a square pole (cuboid) shaped floater that can be transported by truck, and is configured by connecting and assembling a predetermined number of floaters on site.

  This assembly type carrier is described in Patent Document 1. In this assembly type carrier, a male connecting portion that protrudes in the horizontal direction protrudes from a pair of adjacent side surface portions among the four side surface portions of the floater. Moreover, the female pair connection part which can connect a male type connection part is provided in the remaining pair of adjacent side parts. The female connection portion has an insertion hole that can penetrate the male connection portion, and an engagement member is engaged with and connected to the distal end portion of the male connection portion that is inserted through the insertion hole.

  However, the assembly type carrier of Patent Document 1 has a disadvantage that the width of one floater is small, so that it is not stable at the time of assembling (connecting) and disassembling on water, and workability is poor. In other words, considering that the assembly type carrier is used in a field where it is necessary to pass through a narrow road, it is necessary to form the floater with a size that can be loaded on the loading platform of a 4t truck or a 15t truck. And since the male type | mold connection part has protruded from the side part, each floater becomes small by that much. Even if the lateral width is reduced, the volume for obtaining sufficient buoyancy can be secured by increasing the overall height. However, a floater with a high overall height is easy to roll over in a state of being floated on water, and has poor stability.

  Moreover, the assembly-type base boat of patent document 1 makes the state which the male type | mold connection part protruded from the outer peripheral part also in the assembly state. Therefore, a wide gap is generated between the pier and the pier. Therefore, it not only hinders heavy equipment getting on and off, but may cause injury if an operator's leg accidentally enters.

Japanese Patent Laid-Open No. 10-280375

  An object of the present invention is to provide an assembly-type trolley capable of improving stability on water, improving assembly and disassembly workability, and improving safety.

In order to solve the above-mentioned problem, the assembly-type base boat of the present invention is an assembly-type base boat that detachably connects a plurality of floaters having a polygonal column shape having a plurality of side portions surrounding an outer periphery. A connecting member having a mounted portion at one end and a connected portion at the other end is provided, and the first and second side surface portions of the floater extend in the vertical direction and are recessed inward. A groove portion is provided, and a mounting portion for detachably mounting the mounted portion of the connecting member is provided on the groove portion of the first side surface portion so that the connected portion protrudes from the groove portion, and the second side surface A connecting portion for releasably connecting the connected portion of the connecting member is provided in the groove portion of the connecting portion; two or more mounting portions and the connecting portions are provided at predetermined intervals in the vertical direction of the groove portion; and The first connecting part located at the top has a circular shape Rutotomoni provided an insertion hole, provided an insertion slot of the first inverted U-shape having an open lower end to the second connecting portion of the lower except for the connection of and the insertion hole and the insertion slots The connected portion of the connecting member that has been inserted through is engaged by an engaging member that is movably disposed in the groove portion in the vertical direction, and the engaging member is the insertion hole of the first connecting portion. And an engagement groove portion formed of an inverted U-shaped groove corresponding to the insertion groove hole of the second connecting portion .

  In this assembly type carrier, a separate connecting member is detachably attached to connect each floater, so that the width of the floater can be formed as large as possible within a limited space. it can. As a result, since the total height of each floater can be lowered, the stability on water can be improved. Therefore, workability when assembling or disassembling a plurality of floaters on water can be improved.

  Moreover, the assembly-type base boat using this floater can make the clearance gap between the connected floaters small. In addition, a member for connection can be prevented from projecting to the outer peripheral portion of the assembly-type carriage. As a result, the gap with the quay can be reduced at the time of berthing. Therefore, it does not hinder heavy equipment traveling and getting on and off, and worker safety can be secured.

In addition, since the lower second connecting portion excluding the first connecting portion located at the uppermost portion is a substantially inverted U-shaped insertion groove hole, workability when disassembling the assembling type carrier on the water is improved. It can be improved. That is, when disassembling and removing the assembling type carrier, the engagement of the engaging member is released, and the connected portion of the connecting member is detached from the insertion hole only by the upper connecting portion of the adjacent floater. In this state, by lifting the floater upward, the connected portion of the lower connecting member can be detached from the insertion groove hole of the connecting portion. Therefore, the disassembly workability can be greatly improved.

  Further, the mounting portion has a mounting hole through which the mounted portion of the connecting member can be installed, and has a through hole penetrating in a substantially vertical direction, and the mounting pin is passed through the through hole from above. It is preferable that the connecting members are individually attached by the above. If it does in this way, it can prevent mounting | wearing reliably so that a connection member may not drop | omit from a mounting part on the water.

  In the assembly type carrier of the present invention, a separate connecting member is detachably attached to connect each floater, so that the lateral width of the floater can be maximized. Therefore, the overall height of each floater can be lowered, and the stability on water can be improved. As a result, workability during assembly and disassembly can be improved. In addition, the assembled assemblage can reduce the gap between the floaters, and since the connecting member does not protrude from the outer peripheral portion, the gap between the float and the quay can be reduced. Therefore, it does not hinder heavy equipment traveling and getting on and off, and worker safety can be secured.

The upper surface portion 12 is provided with an opening portion for entering and exiting the inside due to maintenance or the like, and the opening portion is sealed with a lid 15. However, the opening positions of the upper surface portion 12 and the lid 15 can be changed as desired. Moreover, the upper surface part 12 is good also as a flat plate shape which does not provide an opening part and the lid | cover 15. FIG. The lower surface part 13 is a flat plate-shaped thing.

  Of the side surface portions 14a to 14d, the long side surface portions 14a and 14c are formed with a size twice as long as the short side surface portions 14b and 14d. Further, the side surface portions 14a to 14d are provided with groove portions 16 extending in the vertical direction along the vertical axis and recessed inward. The groove portions 16 of the side surface portions 14a and 14c are provided at a total of four locations: two locations spaced a predetermined distance from both side edges and two locations spaced a predetermined distance from the center. Further, the groove portions 16 of the side surface portions 14b and 14d are provided at two locations spaced apart from both side edges by a predetermined distance. Thereby, as shown in FIG. 1, the groove part 16 of the side part 14a and the groove part 16 of the side part 14c correspond to a horizontal direction. Moreover, the groove part 16 of the side part 14b and the groove part 16 of the side part 14d correspond to the vertical direction. And it is comprised so that the groove part 16 of the side surface parts 14b and 14d and the groove part 16 of the side surface parts 14a and 14c may correspond in the state which connected a pair of floater (for example, 11E, 11F) to the horizontal direction.

  Further, in the groove portions 16 of the side surface portions 14a to 14d, a groove steel 17 having a concave shape in plan view is disposed. A pair of mounting portions 18 and 18 and connecting portions 21 a and 21 b for releasably connecting the floaters 11 </ b> A to 11 </ b> J via connecting members 25 are provided in the channel steel 17.

The connecting portions 21a and 21b are provided at predetermined intervals in the vertical direction in the groove portions 16 of the other second side surface portions 14c and 14d that face the side surface portions 14a and 14b and are adjacent thereto.

  As shown in FIG. 3, the mounting portion 18 is composed of a rectangular block joined in the groove steel 17 so as to slightly protrude from the groove steel 17 in the horizontal direction. The protruding dimension of the mounting portion 18 is small enough to prevent interference between the side surface portions 14a to 14d of the floaters 11A to 11J to be connected due to manufacturing errors and thermal expansion. The mounting portion 18 is provided with a circular mounting hole 19 that extends in the horizontal direction and can accommodate the mounted portion 26 of the connecting member 25. Further, the mounting portion 18 is provided with a through hole 20 extending in the vertical direction so as to be orthogonal to the axis of the mounting hole 19.

The connecting portions 21a and 21b are plate-like members joined to the open ends of the channel steel 17 so as to slightly protrude from the channel steel 17 in the horizontal direction. The protruding dimensions of the connecting portions 21a and 21b are small enough to prevent the side surface portions 14a to 14d of the floaters 11A to 11J to be connected to interfere with each other, as with the mounting portion 18. A circular insertion hole 22 that can penetrate the connected portion 28 of the connecting member 25 is provided in the connecting portion (first connecting portion) 21 a disposed on the upper side of the channel steel 17. Moreover, the connection part (2nd connection part) 21b arrange | positioned under the channel steel 17 can penetrate the to-be-connected part 28 of the connection member 25, and is the substantially reverse U-shape which open | released the lower end. An insertion groove hole 23 is provided. Furthermore, in this embodiment, the guide 24 which guides the engaging member 31 to the lower connection part 21b is provided in the intermediate position of the groove part 16 which arrange | positions connection part 21a, 21b.

  The connecting member 25 has a columnar shape in which a mounted portion 26 that is detachably attached to the mounting portion 18 is formed at one end, and a connected portion 28 that is detachably connected to the connecting portions 21a and 21b is formed at the other end. belongs to. The mounting portion 26 is provided with a through-hole portion 27 penetrating in the radial direction so as to coincide with the through-hole 20 in a state of being mounted in the mounting portion 18. The front end portion of the connected portion 28 is tapered so as to be easily inserted into the connecting portions 21a and 21b. The connected portion 28 is positioned at a portion (in the grooved steel 17) through which the insertion hole 22 and the insertion groove hole 23 are inserted in a state where the mounting portion 18 and the end surfaces of the connection portions 21a and 21b are in contact with each other. In addition, an engagement groove 29 is provided. The engaging groove 29 is provided so as to extend in parallel to the axis of the through hole portion 27. Thus, the engagement groove 29 is configured to extend in the vertical direction in a state of being mounted on the mounting portion 18. Further, the engaging groove 29 has a side surface located on the side of the connecting portions 21a and 21b extending vertically, and a side surface located on the bottom side of the grooved steel 17 is gradually narrowed from the upper side to the lower side. In this way, it is formed in a substantially right trapezoidal shape extending in an inclined manner.

  The connecting member 25 is individually mounted by penetrating the mounting pin 30 from the upper side with respect to the through hole 20 of the mounting portion 18 in a state where the mounted portion 26 is housed in the mounting portion 18. In this mounted state, the connected portions 28 protrude from the respective groove portions 16 in the horizontal direction. And after the to-be-connected part 28 is inserted with respect to each connection part 21a, 21b, one engagement member 31 is engaged with the engagement groove | channel 29, and is connected so that separation | detachment is possible. .

  The engaging member 31 is formed of a metal plate having a width that can be inserted into the channel steel 17 and having a wall thickness that is larger than the groove width of the engaging groove 29. The total length of the engaging member 31 is slightly smaller than the total height of the channel steel 17. A work hole 32 for engaging and disengaging work is provided at the upper end of the engaging member 31. An engaging hole portion 33 that engages with the engaging groove 29 of the connected portion 28 of the connecting member 25 inserted through the upper connecting portion 21 a is provided at the lower portion of the working hole 32. Further, an engaging groove portion 34 that engages with the engaging groove 29 of the connected portion 28 of the connecting member 25 inserted through the lower connecting portion 21 b is provided at the lower end portion of the engaging member 31. The engaging member 31 has an inclined surface 35 in which the thickness of the portion where the engaging hole portion 33 and the engaging groove portion 34 are formed becomes gradually thinner from the upper side to the lower side. The engagement hole 33 includes a substantially rectangular insertion portion 33a through which the connected portion 28 can be inserted, and an engagement portion that extends upward from the insertion portion 33a and engages with the engagement groove 29 of the connected portion 28. 33b. The engaging groove portion 34 is an inverted U-shaped groove that is engaged with the engaging groove 29 of the connected portion 28. The lower end of the engaging groove 34 is chamfered so that the groove width gradually increases. Further, a lightening portion 36 is provided between the engagement hole portion 33 and the engagement groove portion 34.

  Thus, each floater 11A-11J is comprised so that the connection member 25 of another body may be attached so that attachment or detachment is possible. Therefore, the width of each of the floaters 11A to 11J (the width of the side surfaces 14b and 14d) can be formed as large as possible within a range that can be stacked in a limited space. Specifically, the width of the floaters 11A to 11J of the present invention can be increased to about 2.4 m, compared to about 2.1 m for the conventional floater. As a result, when setting it as the same buoyancy, the total height of each floater 11A-11J can be made low. Moreover, since the width is widened, the stability on water can be improved. Therefore, workability when assembling or disassembling the plurality of floaters 11A to 11J on the water can be improved.

  Specifically, when assembling the carriage 10 using the floaters 11A to 11J, the connecting member 25 is attached to the predetermined side surface portions 14a and 14b, and the side surface portion 14a and the side surface portion 14c, and the side surface portion 14b and the side surface portion. By connecting 14d, the side surface portion 14a and the pair of side surface portions 14d and 14d, and the side surface portion 14c and the pair of side surface portions 14b and 14b so as to face each other, one trolley 10 can be formed.

  Specifically, as shown in FIG. 4A, the mounted portion 26 of the connecting member 25 is inserted into the mounting portion 18. Then, as shown in FIG. 4B, the axis of the through hole 20 of the mounting part 18 and the axis of the through hole part 27 of the connecting member 25 are made to coincide, and the mounting pin 30 is passed through from above. Further, as shown in the drawing, the engaging member 31 is disposed in the groove portion 16 of the connecting portions 21a and 21b and temporarily fixed by a predetermined jig.

  In this state, the floaters 11A to 11J are lifted by a crane and placed on the water. Then, an operator rides on the floaters 11A to 11J floated on the water, the floaters 11A to 11J to be assembled are approached, and the connected portion 28 of the connecting member 25 is connected to the connecting portions 21a and 21b. For example, an operator rides on each of the floaters 11A and 11B and pulls each other with a rope, thereby bringing the side surface portion 14a of the floater 11A closer to the side surface portion 14c of the floater 11B as shown in FIG. 4C. And the to-be-connected part 28 of the connection member 25 with which the mounting part 18 of the floater 11A was mounted is inserted through the connecting parts 21a and 21b of the floater 11B. Thereafter, as shown in FIG. 4D, the engaging member 31 is pushed downward, and the engaging member 31 is engaged with the engaging groove 29 of the coupled portion 28.

  In this way, the desired side surface portions 14a, 14b and the side surface portions 14c, 14d are brought close to each other and connected by the connecting member 25 and the engaging member 31, so that the base boat composed of a large number of floaters 11A to 11J shown in FIG. Assemble 10 with desired shape and area.

  In this base boat 10, the connecting member 25 protruding from the side surface portions 14a, 14b of the first floater 11A is penetrated and connected to the connecting portions 21a, 21b of the side surface portions 14c, 14d of the second floater 11B. A gap between adjacent floaters 11A and 11B can be reduced. Therefore, there is no trouble when heavy equipment travels on the carriage 10, and the safety of the operator can be ensured. Moreover, since the connection member 25 should just be connected only to the side part 14a, 14b to connect, it can be set as the state which the member for connection does not protrude from an outer peripheral part. As a result, the gap with the quay can be reduced at the time of berthing. Therefore, it does not hinder heavy equipment getting on and off, and the safety of workers can be secured.

  In addition, since the connecting member 25 is mounted by penetrating the mounting pin 30 from the upper side with respect to the mounting portion 18, it is securely mounted so that the connecting member 25 does not fall off the mounting portion 18 in a state where it is floated on water. Can be prevented.

  On the other hand, when the work is completed and the carriage 10 is removed, first, the engagement member 31 is lifted upward to release the engagement of the connection member 25 with the connected portion 28. Then, a bar or the like is inserted between the floaters 11A to 11J, and the connected portion 28 of the connecting member 25 is detached from the insertion hole 22 only by the upper connecting portion 21a of the adjacent floaters 11A to 11J as shown in FIG. 5A. . In this state, the floaters 11A to 11J on the side of the connecting portions 21a and 21b are pulled upward. Thereby, as shown to FIG. 5B, the to-be-connected part 28 of the lower side connection member 25 can be made to detach | leave from the insertion groove hole 23 of the connection part 21b.

  Thus, since the trolley 10 of this invention uses the connection part 21b located below the floaters 11A-11J as the insertion groove part which opened the lower end, disassembly workability | operativity can be improved significantly. Then, after all the floaters 11 </ b> A to 11 </ b> J are lifted to the land, the mounting pin 30 is removed and the connecting member 25 is detached from the mounting portion 18.

  In addition, since the trolley 10 of this embodiment is attached only to the side surface parts 14a and 14b which connect the connection member 25, the mounting part 18 of the side surface parts 14a and 14b located in an outer peripheral part is utilized effectively. can do. For example, as shown in FIG. 6A, a rubber buffer 37 for cushioning is mounted on the mounting portion 18 so that the carrier 10 can be prevented from directly interfering at the time of berthing. In addition, as shown in FIG. 6B, a buoy 38 as a mark may be attached to the attachment portion 18.

  Moreover, the assembly-type base boat of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the said embodiment, although the groove part 16 was provided so that it might extend over the upper-lower end of side part 14a-14d, it is good also as a structure provided only in the intermediate part of an upper-lower end.

  Moreover, in the said embodiment, although the mounting part 18 and the connection parts 21a and 21b were provided in two places at predetermined intervals with respect to the groove part 16, you may provide three or more places. In this case, it is preferable that the lower connecting portion excluding the connecting portion 21a located at the uppermost portion is an insertion groove hole 23 having an open lower end. Moreover, the shape and the connection structure of the mounting portion 18, the connection portions 21a and 21b, and the connection member 25 can be changed as desired.

  Furthermore, in the said embodiment, although the floaters 11A-11J were formed in the quadrangular column shape, what is necessary is just to be a polygonal column shape. However, in order to prevent a gap from being generated in the assembled state, it is preferable to use an even-numbered polygonal columnar shape.

  And in the said embodiment, although the groove part 16 was provided in all the side parts 14a-14d and the mounting parts 18 and 18 or the connection parts 21a and 21b were provided, the groove part 16 was provided only in the predetermined side parts 14a-14d. The mounting portions 18 and 18 or the connecting portions 21a and 21b may be provided. However, in this case, it is preferable that the groove portion 16 is provided only on the facing surface, the mounting portions 18 and 18 are provided on one side, and the connecting portions 21a and 21b are provided on the other side.
