Description

[Technical Field]

[0001] The present invention relates to a delivery mechanism for a submersible pump. [Background technology]

[0002] At the site of a river channel closure, the blocked water needs to be quickly drained using a submersible pump to prevent secondary disasters, but care must be taken when entering the disaster site and manually installing the submersible pump. For this reason, a pump vehicle has been proposed in which a submersible pump is loaded onto the bed of a vehicle, transported to the water's edge, and then landed using the vehicle's crane (see, for example, Patent Document 1). Another pump vehicle has been proposed in which a submersible pump is loaded onto the bed of a vehicle, transported to the water's edge, and then landed by sliding it on a running board installed on the water's surface from the bed (see, for example, Patent Document 2).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-240739 [Patent Document 2] Japanese Patent Application Publication No. 6-240740 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the pump vehicles described in Patent Documents 1 and 2 need to approach water, which often involves high water levels or soft ground. This requires the use of large construction machinery or the provision of an amphibious vehicle that can cope with soft ground.

[0005] The present invention has been made in consideration of these points, and aims to provide an underwater pump delivery mechanism that can deliver an underwater pump from above ground into water without the construction machine having to move to the water's edge. [Means for solving the problem]

[0006] One aspect of the present invention is a submersible pump delivery mechanism that delivers a submersible pump from above ground into water, and comprises a leading frame on which the submersible pump is installed and a trailing frame that follows the leading frame, the leading frame and the trailing frame being detachably connected, and the trailing frame being formed so that it can be delivered integrally by pushing out the trailing frame. [Effects of the Invention]

[0007] According to one aspect of the present invention, a trailing frame is connected to a leading frame, and a submersible pump mounted on the leading frame is sent from above ground into water by pushing the trailing frame. The submersible pump is sent into water by the construction machine pushing the trailing frame from a location away from the water's edge, without the construction machine having to move to the water's edge. This means that a submersible pump can be sent into water even with a small construction machine without approaching the water's edge, without using a large construction machine or an amphibious vehicle.

[0009] The following describes the delivery mechanism of the submersible pump of this embodiment. Figure 1 is a perspective view of the delivery mechanism of the submersible pump of this embodiment. Figure 2 is a perspective view of the leading frame of this embodiment. Figure 3 is a perspective view of the trailing frame of this embodiment. Note that while Figure 1 shows an example in which two trailing frames are connected to the leading frame, three or more trailing frames may be connected to the leading frame. In addition, in the following figures, arrow Fr indicates the front of the frame, arrow Re indicates the rear of the frame, arrow L indicates the left side of the frame, and arrow R indicates the right side of the frame.

[0010] As shown in Figure 1, the delivery mechanism 1 for the submersible pump 2 is formed by connecting a lead frame 10 and multiple trailing frames 30. A pair of submersible pumps 2 are installed inside the lead frame 10, and a pair of pump hoses 3 extending from the pair of submersible pumps 2 are passed inside each trailing frame 30 following the lead frame 10. The lead frame 10 and the trailing frames 30 are detachably connected, and the front and rear trailing frames 30 are also detachably connected to each other. By connecting the lead frame 10 and the multiple trailing frames 30, the frame length of the delivery mechanism 1 is extended.

[0011] Four floats 27 are provided on the leading frame 10, and two floats 44 are provided on the trailing frame 30. Each float 27, 44 functions as a handle for construction machinery, and is grasped by construction machinery such as a rotary fork to carry or send out the leading frame 10 and trailing frame 30. The leading frame 10 and the multiple trailing frames 30 are connected in a row, and the rearmost trailing frame 30 is pushed out by the construction machinery, sending out a pair of submersible pumps 2 from above ground away from the water's edge into the water.

[0012] As shown in Figure 2, the lead frame 10 is formed by joining multiple rectangular pillar-shaped metal frames, metal plates, etc. A rectangular parallelepiped installation case 11 for the pair of submersible pumps 2 is formed below the lead frame 10. A pair of upper frames 12 on both the left and right sides extend in the front-to-rear direction (discharge direction) to form the top surface of this installation case 11, and four upper bridges 13 lined up at intervals in the front-to-rear direction extend in the left-to-right direction (width direction). The pair of upper frames 12 are joined via the four upper bridges 13, so that the top surface of the installation case 11 is formed in the shape of a ladder frame.

[0013] Below the pair of upper frames 12 and the four upper bridges 13, a pair of lower frames 14 on both the left and right sides extend in the front-to-rear direction, and four lower bridges 15, spaced apart in the front-to-rear direction, also extend in the left-to-right direction. The pair of lower frames 14 are joined via the four lower bridges 15, forming the underside of the installation case 11 in the shape of a ladder frame. A lower plate 16 is joined to the undersides of the pair of lower frames 14 and the four lower bridges 15. Brackets 17 are joined to the two lower bridges 15 in the middle, and a pair of submersible pumps 2 are fixed to the brackets 17.

[0014] Three side bridges 18 extend in the up-down direction at intervals in the front-to-rear direction between the pair of upper frames 12 and the pair of lower frames 14. The pair of upper frames 12 and the pair of lower frames 14 are each joined via three side bridges 18, forming the side surfaces of the installation case 11 into a ladder frame shape. A pair of arc-shaped front frames 21 extend while curving diagonally downward and rearward from the front ends of the pair of upper frames 12 to the lower ends of the pair of lower frames 14, and a pair of sole frames 22 extend rearward from the rear ends of the pair of front frames 21, passing under the lower plate 16.

[0015] A pair of sliding surfaces 23 extending in the sending-out direction are formed on the undersides of the pair of front frames 21 and the pair of sole frames 22. By forming the pair of sliding surfaces 23 in a line, the contact area of ​​the leading frame 10 is reduced, suppressing frictional resistance. As the left and right sliding surfaces 23 are supported by the ground, the leading frame 10 is sent out in a stable position without swaying left and right. The sliding surfaces 23 of the pair of front frames 21 are inclined so that they rise in the sending-out direction, reducing the chance of the pair of sliding surfaces 23 getting caught on uneven ground, allowing the leading frame 10 to be sent out smoothly.

[0016] A pair of rear upper frames 24 extend diagonally downward and rearward from the rear ends of the pair of upper frames 12, and a pair of rear lower frames 25 extend diagonally upward and rearward from the rear ends of the pair of lower frames 14. The rear ends of the pair of rear upper frames 24 and the rear ends of the pair of rear lower frames 25 are joined via a pair of receiving members 51, and the pair of receiving members 51 are provided at the rear end of the leading frame 10. The pair of receiving members 51 constitute receiving metal fittings of a connecting mechanism for connecting the leading frame 10 and the trailing frame 30 or for connecting the trailing frames 30 together. The detailed configuration of the receiving members 51 will be described later.

[0017] A pair of float frames 26, one at the front and one at the back, are joined to the upper side of the leading frame 10. Four floats 27 are supported on the pair of float frames 26 as handles, and the leading frame 10 is carried by being grasped by construction machinery using the floats 27. Each float 27 is elastically deformed when grasped by the construction machinery, so that even construction machinery that has difficulty in fine-tuning force using hydraulic systems, etc., can grasp the floats 27 without damaging them. In addition, the buoyancy of the floats 27 keeps the submersible pump 2 afloat from the riverbed. Using the floats 27 as handles reduces the number of parts.

[0018] As shown in Figure 3, the trailing frame 30 is formed by joining multiple rectangular pillar-shaped metal frames, metal plates, etc. A pair of hose guides 31 for the submersible pumps 2 are formed on the underside of the trailing frame 30. A pair of upper frames 32 on both the left and right sides extend in the front-to-rear direction (the delivery direction) to form the top surface of this hose guide 31, and five upper bridges 33 lined up at intervals in the front-to-rear direction extend in the left-to-right direction (the width direction). The pair of upper frames 32 are joined via the five upper bridges 33, so that the top surface of the hose guide 31 is formed in the shape of a ladder frame.

[0019] Below the pair of upper frames 32, a pair of lower frames 34 on both the left and right sides extend in the front-to-rear direction. Five side bridges 35 and four support frames 36 are provided between the pair of upper frames 32 and the pair of lower frames 34. The five side bridges 35 extend in the vertical direction at intervals in the front-to-rear direction. The four support frames 36 extend diagonally so as to connect the top and bottom of adjacent side bridges 35 in the front-to-rear direction. The pair of upper frames 32 and the pair of lower frames 34 are joined via the five side bridges 35 and four support frames 36, respectively.

[0020] A pair of front upper frames 37 extend diagonally downward and forward from the front ends of the pair of upper frames 32, and a pair of front lower frames 38 extend diagonally upward and forward from the front ends of the pair of lower frames 34. The front ends of the pair of front upper frames 37 and the front ends of the pair of front lower frames 38 are joined via a pair of hanging members 61, and the pair of hanging members 61 are provided at the front end of the trailing frame 30. The pair of hanging members 61 constitute hanging fittings of a connecting mechanism for connecting the leading frame 10 and the trailing frame 30 or for connecting the trailing frames 30 together. The detailed configuration of the hanging members 61 will be described later.

[0021] A pair of sliding surfaces 39 extending in the feed-out direction are formed on the undersides of the pair of front lower frames 38 and the pair of lower frames 34. By forming the pair of sliding surfaces 39 in a line, the contact area of ​​the trailing frame 30 is reduced, thereby suppressing frictional resistance. Because the left and right sliding surfaces 39 are supported by the ground, the trailing frame 30 is sent out in a stable position without swaying left and right. The sliding surfaces 39 of the pair of front lower frames 38 are inclined so that they rise in the feed-out direction, reducing the chance of the pair of sliding surfaces 39 getting caught on uneven ground, allowing the trailing frame 30 to be sent out smoothly.

[0022] A pair of rear upper frames 41 extend diagonally downward and rearward from the rear ends of the pair of upper frames 32, and a pair of rear lower frames 42 extend diagonally upward and rearward from the rear ends of the pair of lower frames 34. The rear ends of the pair of rear upper frames 41 and the rear ends of the pair of rear lower frames 42 are joined via a pair of receiving members 51, and the pair of receiving members 51 are provided at the rear end of the trailing frame 30. The receiving members 51 of the trailing frame 30 are configured in the same manner as the receiving members 51 of the leading frame 10. By providing the pair of receiving members 51 at the rear end of the trailing frame 30, another trailing frame 30 can be detachably connected behind the trailing frame 30.

[0023] A pair of front and rear float frames 43 are joined to the upper side of the following frame 30. Two floats 44 are supported on the pair of float frames 43 as handles, and the following frame 30 is carried by being grasped by construction machinery using the floats 44. Each float 44 is elastically deformed when grasped by the construction machinery, so that even construction machinery that has difficulty in fine-tuning force using hydraulic systems, etc., can grasp the floats 44 without damaging them. In addition, the buoyancy of the floats 44 keeps the submersible pump 2 afloat from the riverbed. Using the floats 44 as handles reduces the number of parts.

[0024] In this way, in the delivery mechanism 1 for the submersible pump 2, the lead frame 10 forms the framework of the installation case 11 for the submersible pump 2, and the trailing frame 30 forms the framework of the hose guide 31 for the submersible pump 2. When the lead frame 10 and the trailing frame 30 are delivered into the water, water resistance is reduced and the lead frame 10 and the trailing frame 30 are made lighter. Because the front of the lead frame 10 is open, the suction of the submersible pump 2 is not obstructed by the lead frame 10. In addition, the pump hose 3 is guided by the trailing frame 30.

[0025] The connecting mechanism of this embodiment will be described with reference to Figures 4 to 6. Figure 4 is a perspective view of the receiving member of this embodiment. Figure 5 is a perspective view of the hanging member of this embodiment. Figure 6 is an explanatory diagram of the connecting operation of the connecting mechanism of this embodiment. Note that in Figure 5, part of the rocking lever hidden by the hook plate is shown by a dashed line.

[0026] As shown in FIG. 4 , the receiving member 51 has a base plate 52 joined to the rear ends of the leading frame 10 and the trailing frame 30. The base plate 52 is formed in the shape of a vertically long rectangular plate, and a pair of guide plates 53 are joined to both side edges of the base plate 52. The lower parts of the pair of guide plates 53 are connected via horizontal connecting pipes (columnar parts) 55. The upper parts of the pair of guide plates 53 are bent outward in the left-right direction to form guide surfaces 54. The distance between the opposing guide surfaces 54 increases upward, and the hanging member 61 is guided by the guide surfaces 54 toward the connecting pipe 55.

[0027] As shown in Fig. 5, the hanging member 61 has a base plate 62 joined to the front ends of the leading frame 10 and the trailing frame 30. The base plate 62 is formed in the shape of a vertically long rectangular plate, and a pair of hook plates (hooks) 63 are joined to the front surface of the base plate 62, spaced apart in the left-right direction. The hanging openings of the pair of hook plates 63 open downward, and the opening width of the hanging openings of the pair of hook plates 63 is formed to be larger than the diameter of the connecting pipe 55. The lower tips of the pair of hook plates 63 are connected via a fixing pin 64, and the upper parts of the pair of hook plates 63 are connected via a support pin 65.

[0028] A generally C-shaped swing lever (lever) 66 is swingably supported on the support pin 65. One side (the upper side in the figure) of the swing lever 66 serves as an operating arm 67, and the other side (the lower side in the figure) of the swing lever 66 serves as a lock arm 68 that is generally L-shaped in side view. The swing lever 66 swings when the operating arm 67 comes into contact with or separates from the connecting pipe 55 of the receiving member 51. When the operating arm 67 is in a non-operated state, the opening of the swing lever 66 faces downward, and the hooking holes of the pair of hook plates 63 are opened. When the operating arm 67 is in an operated state, the opening of the swing lever 66 faces forward, and the lock arm 68 closes the hooking holes of the pair of hook plates 63.

[0029] The swing lever 66 is also formed with an upper side surface 71 and a lower side surface 72 that face the base plate 62. The upper side surface 71 is formed so as to move away from the base plate 62 in parallel when the hook opening is closed, and the lower side surface 72 is formed so as to abut against the base plate 62 when the hook opening is open. A lock pin 75 is supported between the pair of hook plates 63 by a bolt 73 and a nut 74 so as to be able to slide up and down. The lock is released when the lock pin 75 is lifted by the upper side surface 71 (see FIG. 6(A)), and is locked when the lock pin 75 drops between the upper side surface 71 and the base plate 62 (see FIG. 6(C)).

[0030] The connecting operation of the connecting mechanism will be described below. As shown in Figure 6(A), when the receiving member 51 and the hanging member 61 are in a disconnected state, the center of gravity of the swing lever 66 is toward the rear, so that the lower side surface 72 of the swing lever 66 abuts against the base plate 62. The operating arm 67 is positioned deep inside the hooking openings of the pair of hook plates 63, and the locking arm 68 is retracted from the hooking openings of the pair of hook plates 63. The openings of the swing lever 66 overlap with the hooking openings of the pair of hook plates 63, opening the hooking openings of the pair of hook plates 63. In addition, the lock pin 75 is lifted by the upper side surface 71 of the swing lever 66, releasing the lock.

[0031] 6(B), when the hanging member 61 is brought close to the receiving member 51 from above, the pair of hook plates 63 of the hanging member 61 are guided toward the connecting pipe 55 by the guide surfaces 54 of the pair of guide plates 53 of the receiving member 51. The pair of hook plates 63 are lowered along the guide surfaces 54 of the pair of guide plates 53, and are smoothly guided to the connecting pipe 55. As described above, because the hanging openings of the pair of hook plates 63 are open, the pair of hook plates 63 enter inside the pair of guide plates 53, and the connecting pipe 55 begins to enter into the hanging openings of the pair of hook plates 63.

[0032] As shown in Figure 6(C), when the connecting pipe 55 enters the depths of the hook openings of the pair of hook plates 63, the connecting pipe 55 pushes up the operating arm 67, moving the swing lever 66. The lock arm 68 closes the hook openings of the pair of hook plates 63, connecting the receiving member 51 and the hanging member 61. The lower side surface 72 of the swing lever 66 moves away from the base plate 62, and the upper side surface 71 of the swing lever 66 faces the base plate 62 with a gap between them. A lock pin 75 drops into the gap between the upper side surface 71 of the swing lever 66 and the base plate 62, locking the receiving member 51 and the hanging member 61 in a connected state.

[0033] In this way, the pair of hook plates 63 support swing levers 66 that open and close the hanging openings, and the swing levers 66 are moved by the connecting pipe 55 that is inserted into the hanging openings to close the hanging openings. For example, the leading frame 10 and the trailing frame 30 can be easily connected by lowering the trailing frame 30 onto the leading frame 10 with a construction machine. In addition, the swing levers 66 that close the hanging openings of the pair of hook plates 63 are locked by a lock pin 75. The connecting pipe 55 is prevented from coming off the pair of hook plates 63, and the connection between the leading frame 10 and the trailing frame 30 will not be unintentionally released.

[0034] The unwinding operation of the pump hose will be described with reference to Fig. 7. Fig. 7 is an explanatory diagram of the unwinding operation of the pump hose of this embodiment.

[0035] As shown in Figures 7(A) and 7(B), the leading frame 10 is carried on a vessel 81 of an off-road transport vehicle (transport vehicle) 80. A pair of support posts 82 are provided on the vessel 81, spaced apart in the width direction, and a payout reel 83 is rotatably supported between the pair of support posts 82. A pump hose 3 is wound around the payout reel 83, and the tip of the pump hose 3 is connected to a submersible pump 2 installed on the leading frame 10. When the off-road transport vehicle 80 arrives at its destination, the vessel 81 is tilted, and the leading frame 10 slides down toward the ground while the pump hose 3 is paid out from the payout reel 83.

[0036] As shown in Figures 7(C) and 7(D), when the leading frame 10 is lowered to the ground, the off-road transport vehicle 80 moves away from the leading frame 10, causing the pump hose 3 to be unwound from the unwinding reel 83. Because the leading frame 10 and the submersible pump 2 have sufficient weight, the pump hose 3 is unwound from the unwinding reel 83 as the off-road transport vehicle 80 moves, without the leading frame 10 moving. The pump hose 3 is easily laid as the off-road transport vehicle 80 moves. In addition, the submersible pump 2 is protected by the leading frame 10 during transport and unloading by the off-road transport vehicle 80.

[0037] The sending-out operation of the sending-out mechanism will be described with reference to Fig. 8. Fig. 8 is an explanatory diagram of the sending-out operation of the sending-out mechanism of this embodiment. Note that although the symbols a and b are assigned to subsequent frames in Fig. 8, the symbols a and b may be omitted if no particular subsequent frame is specified.

[0038] As shown in Figure 8(A), when the leading frame 10 is lowered to a location away from the water's edge, the trailing frame 30a, held by the construction machine 85, is carried to the rear of the leading frame 10. The pair of hanging members 61 at the front end of the trailing frame 30a are aligned with the pair of receiving members 51 at the rear end of the leading frame 10, and the construction machine 85 lowers the trailing frame 30a behind the leading frame 10, connecting the leading frame 10 and the trailing frame 30a via the receiving members 51 and the hanging members 61. The pump hose 3 extending from the submersible pump 2 of the leading frame 10 is positioned inside the trailing frame 30a.

[0039] As shown in Figure 8(B), when the leading frame 10 and the trailing frame 30a are connected, the construction machine 85 pushes out the trailing frame 30a, and the leading frame 10 and the trailing frame 30a are sent out as a unit. As shown in Figure 8(C), the construction machine 85 grasps the next trailing frame 30b, and the trailing frame 30b grasped by the construction machine 85 is carried to the rear of the trailing frame 30a. The construction machine 85 lowers the trailing frame 30b behind the trailing frame 30a, and the trailing frames 30a, 30b are connected via the receiving member 51 and the hanging member 61.

[0040] As shown in Figure 8(D), when the leading frame 10 and the trailing frames 30a, 30b are connected, a single long frame is formed that extends from the work site of the construction machine 85 toward the water's edge. The construction machine 85 pushes out the rearmost trailing frame 30b, and the leading frame 10 and the trailing frames 30a, 30b are sent out together until the submersible pump 2 of the leading frame 10 is submerged in water. By integrating the leading frame 10 and the trailing frames 30a, 30b, the construction machine 85 can carry out the work of sending out the submersible pump 2 without approaching soft ground or the water's edge where the water level may rise.

[0041] As described above, according to the delivery mechanism 1 for the submersible pump 2 of this embodiment, the trailing frames 30a, 30b are connected to the leading frame 10, and the submersible pump 2 mounted on the leading frame 10 is delivered from above ground into water by pushing the trailing frame 30b. The submersible pump 2 is delivered into water by the construction machine 85 pushing the trailing frame 30b from a location away from the water's edge, without the need for the construction machine 85 to move to the water's edge. Therefore, the submersible pump 2 can be delivered into water even with a small construction machine without approaching the water's edge, without using a large construction machine or amphibious vehicle.

[0042] In this embodiment, the first frame and two subsequent frames are connected, but the first frame and one subsequent frame may also be connected, or the first frame and three or more subsequent frames may also be connected.

[0043] In this embodiment, the leading frame has a framework structure, but the leading frame is not particularly limited in structure as long as it can accommodate a submersible pump. Similarly, the trailing frame has a framework structure, but the trailing frame is not particularly limited in structure as long as it follows the leading frame.

[0044] Furthermore, in this embodiment, a pair of submersible pumps are installed on the leading frame, but one submersible pump may be installed on the leading frame, or three or more submersible pumps may be installed.

[0045] In addition, in this embodiment, the receiving member is provided on the leading frame and the hanging member is provided on the trailing frame, but the hanging member may be provided on the leading frame and the receiving member may be provided on the trailing frame.

[0046] Furthermore, in this embodiment, floats are provided as handles on the leading frame and the trailing frame, but the handles are not particularly limited as long as they are formed so as to be elastically deformable when gripped by the construction machine.

[0047] Furthermore, in this embodiment, a rotary fork is used as an example of a construction machine, but the construction machine is not particularly limited as long as it is capable of pushing in the trailing frame.

[0048] Furthermore, in this embodiment, an off-road transport vehicle is exemplified as the transport vehicle, but the transport vehicle is not particularly limited as long as it is capable of transporting the leading frame.

[0049] Furthermore, as long as the leading frame and the trailing frame are detachably connected, the connecting structure of the leading frame and the trailing frame is not limited.

[0050] As described above, the first aspect is a submersible pump delivery mechanism (1) that delivers a submersible pump (2) from land to underwater. The mechanism includes a leading frame (10) on which the submersible pump is mounted and a trailing frame (30) that follows the leading frame. The leading frame and the trailing frame are detachably connected, and the trailing frame and the leading frame can be delivered together by pushing out the trailing frame. With this configuration, the trailing frame is connected to the leading frame, and the submersible pump mounted on the leading frame is delivered from land to underwater by pushing in the trailing frame. The submersible pump is delivered underwater by pushing the trailing frame from a location away from the water's edge, without the construction machine having to move to the water's edge. Therefore, a submersible pump can be delivered underwater even with a small construction machine without approaching the water's edge, without using a large construction machine or an amphibious vehicle.

[0051] In the second embodiment, the trailing frame of the first embodiment is provided with a handle (float 44) that elastically deforms when grasped by the construction machine (85). With this configuration, the trailing frame is carried by the construction machine via the handle. Even in construction machines where fine adjustment of force is difficult using hydraulic systems or the like, the float's elastic deformation allows the frame to be grasped without being damaged.

[0052] In the third aspect, the handle of the second aspect is a float. With this configuration, the buoyancy of the float keeps the submersible pump off the riverbed. Using the float as the handle reduces the number of parts.

[0053] In a fourth aspect, in any one of the first to third aspects, a pair of sliding surfaces (23, 39) extending in the sending-out direction are formed on the leading frame and the trailing frame. With this configuration, the contact surfaces of the leading frame and the trailing frame are made small, thereby suppressing frictional resistance and allowing the leading frame and the trailing frame to be sent out in a stable posture.

[0054] In the fifth aspect, the front sides of the pair of sliding surfaces are inclined in the direction of release in the fourth aspect, reducing the risk of the sliding surfaces getting caught on uneven ground, allowing the leading and trailing frames to be released smoothly.

[0055] In a sixth aspect, in any one of the first to fifth aspects, the leading frame forms the framework of the submersible pump installation case (11), and the trailing frame forms the framework of the submersible pump hose guide (31). This configuration reduces water resistance when the leading frame and trailing frame are sent out into the water, and also reduces the weight of the leading frame and trailing frame. In addition, the leading frame does not impede the suction of the submersible pump. Furthermore, the trailing frame can guide the pump hose.

[0056] The seventh aspect is any one of the first to sixth aspects, in which a horizontal pillar-like portion (connecting pipe 55) is provided at the rear end of the leading frame, a downward-opening hook (hook plate 63) is provided at the front end of the trailing frame, a lever (swing lever 66) that opens and closes the hanging opening is swingably supported on the hook, and the lever is moved by the pillar-like portion inserted into the hook's hanging opening to close the hanging opening. With this configuration, the leading frame and the trailing frame can be easily connected by lowering the trailing frame onto the leading frame with construction machinery.

[0057] In the eighth aspect, in the seventh aspect, the hook is provided with a locking member (lock pin 75) that locks the lever that closes the hanging opening. This configuration prevents the pillar from coming off the hook, and prevents the connection between the leading frame and the trailing frame from being unintentionally released.

[0058] In a ninth aspect, in the seventh or eighth aspect, the leading frame is provided with a guide plate (53) that guides the hook toward the pillar-shaped portion. With this configuration, the hook is smoothly guided along the guide plate to the pillar-shaped portion.

[0059] In a tenth aspect, in any one of the first to ninth aspects, a pump hose connected to the submersible pump is wound around a payout reel (83) on a transport vehicle (rough terrain transport vehicle 80), and the pump hose is paid out from the payout reel when the transport vehicle moves away from the leading frame lowered to the ground. With this configuration, the pump hose of the submersible pump can be easily laid by the transport vehicle traveling.

[0060] Although the present embodiment and modifications have been described, other embodiments may be obtained by combining the above-described embodiments and modifications in whole or in part.

[0061] Furthermore, the technology of the present invention is not limited to the above-described embodiments, and may be variously changed, substituted, or modified within the scope of the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of symbols]
