Description
Technical Field
[0001] The utility model relates to the technical field of buoyancy boxes, in particular to a buoyancy box with surge buffering performance. Background Art
[0002] At present, multifunctional small pontoons are mainly used for salvage and rescue and material transportation in flood relief and emergency response. Many heavy rescue equipment need to be placed on an operating platform spliced with multifunctional small pontoons.
[0003] The multifunctional small pontoon is suitable for the form of a single box or multiple boxes combined into a floating platform on rivers with a flow rate of no more than 2.5m / s. It can ensure that one or several operators can carry out rescue and salvage operations on the platform and transfer personnel and materials on the platform. In the textbook, there is no clear requirement for the applicable wind and wave level of the equipment. It only needs to be used with caution within the wind and wave height of 1.2 meters. Some general requirements are made - the flow rate is small, the water depth is appropriate, and there are no obstacles on the river bottom; but there are no clear requirements for the weight of the salvaged items during use and the frequency and range of movement of personnel and items. With the continuous development of new technical equipment, the number of medium and heavy rescue equipment is increasing, and the degree of mechanization and groupization is constantly improving. The harsh conditions around the clock require the rescue and support teams to give full play to the maximum efficiency of their equipment and complete the rescue and salvage tasks in flood control and emergency rescue.
[0004] However, the multifunctional small pontoon has a small carrying capacity in the form of a single box, and can only carry one person. It has poor stability and cannot be used for salvage operations. When four or more pontoons are spliced together (maximum splicing number 6×6), it can only meet the rescue, salvage and transfer operations when the wind and waves are relatively small. When the maximum splicing number is 6×6, heavy (large) rescue equipment and salvaged materials can only be used with caution, and the efficiency is very low. In addition, the small pontoon itself is greatly damaged during use, and the damage is more serious in the case of wind and waves. In addition, when transferring salvage materials and moving personnel in the case of wind and waves, there are more and more serious damage factors to the equipment.
[0005] Through daily training, use and maintenance of the multifunctional small pontoon, it was found that wind, waves, swells and the movement of loads during loading caused the small pontoon to rise and fall and swing left and right, which mainly aggravated the wear of the ear seat and buckle of the deck buckle and the longitudinal tensioning device, and even caused breakage, damage and slippage.
[0006] The technical performance and applicable environment of the multifunctional small pontoon are important prerequisites for successfully completing the salvage and rescue mission in flood control and rescue. Improving the technical performance and applicable environment of the multifunctional small pontoon is of great significance for completing the flood control and rescue mission. Utility Model Content
[0007] The utility model aims to solve the problems in the prior art that, due to wind and waves, swells and the movement of loads during the bearing process, a small buoyancy box may rise and fall, swing left and right, etc., causing serious wear and even damage to the ear seat, buckle and longitudinal tensioning device of the deck buckle; and heavy (large) rescue equipment can only be moved cautiously and has very low utilization efficiency. The utility model provides a buoyancy box with surge buffering performance.
[0008] The technical solution of the utility model to solve the above technical problems is as follows:
[0009] A buoyancy box with surge buffering performance comprises a plurality of boxes spliced to each other, the tops of two adjacent boxes being movably connected by an arched latch hinge connection device, the arched latch hinge connection device comprising two spring steels, the spring steels being in an arched structure, the two spring steels being respectively connected to opposite sides of two adjacent boxes, the two ends of the spring steels being respectively hinged with a mounting piece 1 and a mounting piece 2, the mounting piece 1 at one end of the spring steel being rotatably connected to the mounting piece 2 at the other end of the spring steel; the bottoms of the two adjacent boxes are movably connected by a pin hinge connection device.
[0010] By adopting the above technical scheme, the tops of multiple boxes are assembled and connected using an arched latch hinge connection device, and the bottoms of multiple boxes are assembled and connected using a pin hinge connection device. Since the spring steel has an arched structure, the two ends of the spring steel are respectively hinged to the mounting piece one and the mounting piece two, and the connected mounting piece one and the mounting piece two are rotatably connected, so that the arched latch hinge connection device has a certain bidirectional elastic force, which is used to overcome or alleviate the ups and downs and left and right swings of the pontoon caused by wind and waves, swells and load movement during use. It can play a buffering role when used in conditions of strong winds and waves and frequent movement of heavy materials, so as to prevent damage to components between the multifunctional pontoons and improve wear resistance.
[0011] Furthermore, the first mounting piece is provided with a protrusion, the second mounting piece is provided with a groove, the protrusion is embedded in the groove and connected by a first bolt, and the first mounting piece and the second mounting piece rotate around the first bolt.
[0012] By adopting the above technical solution, the protrusion is embedded in the groove and connected by bolt one, which can realize the rotation connection between mounting member one and mounting member two, and the detachable connection between mounting member one and mounting member two, thereby realizing the detachable connection of two spring steels.
[0013] Furthermore, the pin-hinged connection device includes multiple connection blocks 1 and multiple connection blocks 2, and the connection blocks 1 and connection blocks 2 are respectively connected to the opposite sides of two adjacent boxes, and the connection blocks 1 and connection blocks 2 correspond to each other, and the corresponding connection blocks 1 and connection blocks 2 are rotatably connected.
[0014] By adopting the above technical solution, the pin-hinged connection device composed of connecting block one and connecting block two can move freely within a certain range. When the working surface of the box moves due to surges or the transfer of heavy materials, the gap between the two buoyant boxes becomes larger, and the pin-hinged connection device moves freely. Under the action of its own elastic force, the gap between the two boxes is reduced, which plays a buffering role to prevent component damage and improve wear resistance.
[0015] Furthermore, the cross-section of the connecting block one is a "concave" shape, and the cross-section of the connecting block two is a "convex" shape. The connecting block two is inserted into the connecting block one and connected by bolt two, and the connecting block one and the connecting block two rotate around the bolt two.
[0016] By adopting the above technical solution, the protruding part of the connecting block 2 is inserted into the concave part of the connecting block 1, and connected by bolt 2, which can realize both the rotational connection between the connecting block 1 and the connecting block 2 and the detachable connection between the connecting block 1 and the connecting block 2, thereby realizing the detachable connection of the bottoms of the two adjacent boxes.
[0017] Furthermore, a surge inertia damping plate is provided at the bottom of the box body, and the surge inertia damping plate is located outside the box body. The surge inertia damping plate is lifted and lowered by a lifting device.
[0018] By adopting the above technical scheme, a double-layer structure combining a sealed box and a surge inertia damping plate is used. When the floating box rises and falls and swings left and right to a large extent due to the movement of the load during the process of wind and waves, large surges and the movement of heavy materials, the operating personnel adjust the lifting device to make the surge inertia damping plate installed at the bottom of the sealed box drop to a certain depth as required, and a certain hollow space is formed between the sealed box and the surge inertia damping plate. The difference between the gravity of the water in the hollow space and the adhesion between water and water, the adhesion between water and the box surface, the upward buoyancy of the floating box, the upward surge force of the surge, the downward gravity of the floating box, and the downward surge force of the surge is utilized to reduce the degree of up and down movement and left and right swing of the sealed box.
[0019] Furthermore, the lifting device includes an operating rod, which extends from the top of the box into the interior of the box. A driving gear is fixed on the operating rod, and a driven gear is meshed on the driving gear. The internal thread of the driven gear is connected to a screw, and the screw is connected to the surge inertia damping plate. The driving gear and the driven gear are both located inside the box.
[0020] By adopting the above technical solution, the operator turns the operating lever to make the operating lever drive the active gear to rotate, the active gear drives the driven gear meshing with it to rotate, the driven gear drives the lead screw threadedly connected to it to perform lifting movement, and the lead screw drives the surge inertia damping plate connected to it to perform lifting movement, so that a certain hollow space can be formed between the sealing box and the surge inertia damping plate.
[0021] Furthermore, the operating rod, the driving gear, the driven gear and the lead screw are collectively sleeved with a limiting sleeve on their exteriors, and the limiting sleeve is connected to the box body.
[0022] By adopting the above technical solution, the limit sleeve is used to limit the operating rod, the driving gear and the driven gear to only perform rotational movement, so that the lead screw performs lifting movement and drives the surge inertia damping plate to perform lifting movement.
[0023] Furthermore, the limiting sleeve includes a limiting ring, and the driving gear and the driven gear are both located inside the limiting ring.
[0024] By adopting the above technical solution, since the driving gear and the driven gear are both located inside the limiting ring, the limiting ring can limit the movement process of the driving gear and the driven gear, so that the driving gear and the driven gear only perform rotational movement but not lifting movement.
[0025] Furthermore, there are four groups of lifting devices, and the four groups of lifting devices are respectively arranged near the four corners of the box body.
[0026] By adopting the above technical solution, the four sets of lifting devices arranged near the four corners of the box can simultaneously drive the surge inertia damping plate to perform lifting movement, so that the force acting on the surge inertia damping plate is more balanced, which is more conducive to realizing the lifting movement of the surge inertia damping plate and exerting a buffering effect.
[0027] In summary, compared with the prior art, the above technical solution has the following beneficial effects:
[0028] (1) The spring steel is in an arched structure, and the two ends of the spring steel are respectively hinged to the mounting member 1 and the mounting member 2, and the connected mounting member 1 and the mounting member 2 are rotatably connected, so that the arched latch hinge connection device has a certain bidirectional elastic force, which is used to overcome or alleviate the ups and downs and left and right swings of the buoy caused by wind and waves, swells and load movement during use. It can play a buffering role when used in the case of strong winds and waves and frequent movement of heavy materials, so as to prevent damage to the components between the multifunctional buoys and improve the wear resistance;
[0029] (3) The pin-hinged connection device composed of the connection block 1 and the connection block 2 can move freely within a certain range. When the working surface of the box moves due to surges or heavy material transfer, the gap between the two buoys becomes larger, and the pin-hinged connection device moves freely. Under the action of its own elastic force, the gap between the two boxes is reduced, playing a buffering role to prevent component damage and improve wear resistance;
[0030] (3) By using a double-layer structure combining a sealed box and a surge inertia damping plate, when there are strong winds and surges or when heavy materials are being moved, the floating box will fluctuate up and down and swing left and right to a large extent due to the movement of the load. The operator can adjust the lifting device to lower the surge inertia damping plate installed at the bottom of the sealed box to a certain depth as required, so that a certain hollow space is formed between the sealed box and the surge inertia damping plate. The difference between the gravity of the water in the hollow space and the adhesion between water and water, the adhesion between water and the box surface, the upward buoyancy of the floating box, the upward surge force of the surge, the downward gravity of the floating box, and the downward surge force of the surge can be used to reduce the degree of up and down fluctuation and left and right swing of the sealed box.

DETAILED DESCRIPTION
[0037] The following is combined with Figure 1-5The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.
[0038] The utility model embodiment discloses a buoyancy box with surge buffering performance.
[0039] Reference Figure 1-Figure 5 A buoyancy box with surge buffering performance comprises a plurality of boxes 1 spliced with each other, the boxes 1 being a trapezoidal structure, the tops of two adjacent boxes 1 being movably connected by an arched latch hinge connection device 2, and the bottoms of two adjacent boxes 1 being movably connected by a pin hinge connection device 3, and being used to overcome or alleviate the ups and downs and left and right swings of the buoyancy box caused by wind and waves, surges and load movement during use, and can play a buffering role when used in conditions of strong winds and waves and frequent movement of heavy materials, so as to prevent damage to components between the multifunctional buoyancy boxes and improve wear resistance.
[0040] Reference Figure 1 and Figure 2 The arched latch hinge connection device 2 includes two spring steels 21, which are in an arched structure. The two spring steels 21 are respectively connected to opposite sides of two adjacent boxes 1. Specifically, the middle of the spring steel 21 is fixedly connected to the box 1, and the two ends of the spring steel 21 are respectively hinged with a mounting piece 1 22 and a mounting piece 23, and the mounting piece 1 22 at the end of one spring steel 21 is rotatably connected with the mounting piece 2 23 at the end of the other spring steel 21, so that the arched latch hinge connection device 2 has a certain bidirectional elastic force, which can play a buffering role when used in the case of strong winds and waves and frequent movement of heavy materials.
[0041] Specifically, a protrusion 221 is fixed on the mounting member 22, and a groove 231 is provided on the mounting member 23. The protrusion 221 is embedded in the groove 231 and connected by a bolt 7, and through holes corresponding to the bolt 7 are provided on the protrusion 221 and the mounting member 2 23. A gap is left at the connecting position of the mounting member 1 22 and the mounting member 2 23, so that the mounting member 1 22 and the mounting member 2 23 can rotate freely around the bolt 7, which can realize the rotation connection between the mounting member 1 22 and the mounting member 2 23, and the detachable connection between the mounting member 1 22 and the mounting member 2 23, thereby realizing the detachable connection between the two spring steels 21.
[0042] Reference Figure 1 and Figure 3The pin-hinged connection device 3 includes a plurality of connection blocks 1 31 and a plurality of connection blocks 2 32, wherein the connection blocks 1 31 and the connection blocks 2 32 are respectively connected to opposite sides of two adjacent boxes 1, and the connection blocks 1 31 and the connection blocks 2 32 correspond to each other, and the corresponding connection blocks 1 31 and the connection blocks 2 32 are rotatably connected. The pin-hinged connection device 3 can move freely within a certain range, and can reduce the gap between the two boxes 1 under the action of its own elastic force, thereby playing a buffering role.
[0043] Specifically, the cross-section of the connecting block 1 31 is a "concave"-shaped structure, and the cross-section of the connecting block 2 32 is a "convex"-shaped structure. The connecting block 2 32 is inserted into the connecting block 1 31 and connected by the bolt 2 8, and the connecting block 1 31 and the connecting block 2 32 are both provided with through holes corresponding to the bolt 2 8. A gap is left at the connecting position of the connecting block 1 31 and the connecting block 2 32, so that the connecting block 1 31 and the connecting block 2 32 can rotate freely around the bolt 2 8, which can realize the rotation connection between the connecting block 1 31 and the connecting block 2 32, and the detachable connection between the connecting block 1 31 and the connecting block 2 32, thereby realizing the detachable connection between the bottoms of the two adjacent boxes 1.
[0044] Reference Figure 1 The bolt 2 8 is perpendicular to the bolt 1 7. Since the box body 1 is a trapezoidal structure, there is a certain space on the upper side of the adjacent surfaces of two adjacent box bodies 1. When the box body 1 fluctuates up and down and swings left and right, the spring steel 21 on the top of the box body 1 will undergo elastic deformation, causing the mounting piece 1 22 and the mounting piece 2 23 to rotate around the bolt 1 7. At the same time, the connecting block 1 31 and the connecting block 2 32 at the bottom of the box body 1 rotate around the bolt 2 8, achieving a buffering effect and reducing the degree of up and down fluctuation and left and right swing of the sealed box body 1.
[0045] Reference Figure 1 and Figure 4 The bottom of the box 1 is provided with a surge inertia damping plate 4, and the surge inertia damping plate 4 is located outside the box 1, so as to obtain a double-layer structure combining the sealed box 1 and the surge inertia damping plate 4. The surge inertia damping plate 4 is lifted and lowered by a lifting device 5. Specifically, the operator adjusts the lifting device 5 to make the surge inertia damping plate 4 installed at the bottom of the sealed box 1 drop to a certain depth as required, and a certain hollow space is formed between the sealed box 1 and the surge inertia damping plate 4. The gravity of the water in the hollow space, the adhesion between water and water, the adhesion between water and the surface of the box 1, the upward buoyancy of the buoyancy box, the upward surge force of the surge, the downward gravity of the buoyancy box, and the downward surge force of the surge are used to reduce the degree of ups and downs and left and right swings of the sealed box 1.
[0046] Reference Figure 1 and Figure 4There are four groups of lifting devices 5, which are respectively arranged near the four corners of the box body 1 and respectively correspond to the four corners of the surge inertia damping plate 4. The four groups of lifting devices 5 can simultaneously drive the surge inertia damping plate 4 to perform lifting motion, so that the force acting on the surge inertia damping plate 4 is more balanced, which is more conducive to realizing the lifting motion of the surge inertia damping plate 4 and exerting a buffering effect.
[0047] Reference Figure 1 , Figure 4 and Figure 5 The lifting device 5 includes an operating rod 51, which extends from the top of the box body 1 into the interior of the box body 1. A driving gear 52 is fixed on the operating rod 51, and a driven gear 53 is meshed on the driving gear 52. Both the driving gear 52 and the driven gear 53 are located inside the box body 1. The internal thread of the driven gear 53 is connected with a lead screw 54, and the lead screw 54 is connected to the surge inertia damping plate 4. The operator twists the operating rod 51, so that the operating rod 51 drives the driving gear 52 to rotate, the driving gear 52 drives the driven gear 53 to rotate, the driven gear 53 drives the lead screw 54 to perform lifting and lowering movements, and the lead screw 54 drives the surge inertia damping plate 4 to perform lifting and lowering movements, so that a certain hollow space can be formed between the sealed box body 1 and the surge inertia damping plate 4.
[0048] Reference Figure 4 and Figure 5 The operating rod 51, the driving gear 52, the driven gear 53 and the lead screw 54 are collectively sleeved with a limit sleeve 6 on the outside, and the limit sleeve 6 is fixedly connected to the box body 1. The limit sleeve 6 can limit the operating rod 51, the driving gear 52 and the driven gear 53 to only perform rotational movement, so that the lead screw 54 performs lifting movement and drives the surge inertia damping plate 4 to perform lifting movement.
[0049] Reference Figure 4 and Figure 5 The limiting sleeve 6 includes a limiting ring 61, and the driving gear 52 and the driven gear 53 are both located inside the limiting ring 61, so that the limiting ring 61 can limit the movement process of the driving gear 52 and the driven gear 53, so that the driving gear 52 and the driven gear 53 only perform rotational movement and do not perform lifting movement.
[0050] The implementation principle of the buoyancy box with surge buffering performance in the embodiment of the utility model is as follows: in the process of wind and waves, large surges and the movement of heavy materials, when the buoyancy box rises and falls and swings left and right to a large extent due to the movement of the load, the arched latch hinge type connection device 2 has a certain bidirectional elastic force, which can play a buffering role; the pin hinge connection device 3 can move freely within a certain range, and when the gap between the two buoyancy boxes becomes larger, the pin hinge connection device 3 moves freely, and under the action of its own elastic force, the gap between the two boxes 1 is reduced, playing a buffering role. The operator can lower the surge inertia damping plate 4 installed at the bottom of the sealed box 1 to a certain depth as needed by twisting the operating rod 51 of the lifting device 5, and form a certain hollow space between the sealed box 1 and the surge inertia damping plate 4. The gravity of the water in the hollow space, the adhesion between water and water, the adhesion between water and the surface of the box 1, the upward buoyancy of the floating box, the upward surge force of the surge, the downward gravity of the floating box, and the downward surge force of the surge can be used to reduce the degree of up and down fluctuation and left and right swing of the sealed box 1.
