Description

Technical Field

[0001] This invention relates to the field of shipboard equipment technology, and in particular to a shock-absorbing base for the engine room of a trailing suction hopper dredger. Background Technology

[0002] Dredgers are responsible for clearing silt from waterways and rivers to allow other vessels to pass smoothly. Types include cutter suction dredgers and trailing suction hopper dredgers. A generator set is typically installed in the engine room of a dredger. A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. Before use, the entire generator set needs to be installed on the base; however, most existing bases are designed for one type of generator set and cannot accommodate other types, presenting certain limitations. Furthermore, the generator set generates significant vibration during operation.

[0003] Chinese patent application number CN202122108777.8 discloses a shock-absorbing generator base. It uses a sleeve and a buffer plate between the base plate and the mounting plate to buffer vibrations as the buffer plate moves up and down. A guide rod and a return spring further buffer vibrations. A slider on the mounting plate effectively limits and fixes generator sets of different sizes. However, in actual use, this base cannot limit and fix the upper side of the generator set, causing it to loosen due to vibration during operation. Furthermore, because the second positioning plate is fixed in one place, the generator set, regardless of size, must be installed close to the second positioning plate, resulting in an off-center installation position and affecting the overall shock absorption effect of the base. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a shock-absorbing base for the engine room of a trailing suction hopper dredger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A shock-absorbing base for the engine room of a trailing suction hopper dredger includes a base fixed to the engine room by bolts. A plurality of shock absorbers are fixedly mounted on the top of the base. A mounting seat is fixedly mounted on the top of each shock absorber. The mounting seat is provided with a lower clamping assembly for clamping a generator set and an upper clamping assembly for clamping the upper side of the generator set. A transmission gearbox is provided between the upper clamping assembly and the lower clamping assembly. The transmission gearbox is fixedly mounted in the base. The lower clamping assembly is provided with auxiliary ball bearings that are slidably connected to the generator set and an auxiliary support structure for supporting the generator set.

[0006] Preferably, the lower clamping assembly includes a bidirectional screw rotatably connected within the mounting base, the input shaft of the transmission gearbox is connected to the bidirectional screw, a knob is provided at the end of the bidirectional screw, two opposing sleeves are threadedly connected to the bidirectional screw, each sleeve is provided with a lower clamping plate, and the mounting base is provided with a sliding groove for the sleeve to slide.

[0007] Preferably, the lower clamping plate includes a side plate disposed on the upper side of the sleeve and a bottom plate fixedly connected to the side plate, and the bottom plates of the lower clamping plates on both sides of the mounting base are slidably staggered, and the auxiliary ball bearings are disposed on the side plate and the bottom plate.

[0008] Preferably, a connecting plate is fixedly provided on the outer side of the side plate, and a sliding plate fixedly connected to the sleeve is slidably connected inside the connecting plate. A first elastic element is provided between the sliding plate and the connecting plate.

[0009] Preferably, the upper clamping assembly includes rotating rods rotatably connected to both sides of the mounting base, each of the rotating rods being fixed with an upper clamping plate that moves against the generator set, and the output shaft of the transmission gearbox being connected to the rotating rod.

[0010] Preferably, the auxiliary support structure includes an elastic telescopic tube fixed in the lower clamping plate, the elastic telescopic tube being inclined to the side plate and the bottom plate, and one end of the elastic telescopic tube being fixed to an L-shaped plate that slides in the lower clamping plate.

[0011] Preferably, the auxiliary support structure further includes a force-bearing block slidably connected within the upper clamping plate. The upper clamping plate has a movable groove for sliding the force-bearing block. An elastic telescopic rod is also provided between the inner wall of the movable groove and the force-bearing block. A pull rope is fixed on the force-bearing block. The end of the pull rope away from the force-bearing block passes through the upper clamping plate, the mounting base, the L-shaped plate, and the lower clamping plate in sequence and is connected to the telescopic end of the elastic telescopic tube.

[0012] Preferably, a groove is provided in the side plate, a movable plate is slidably connected in the groove, a second elastic element is provided between the movable plate and the inner wall of the groove, an elastic telescopic rod is fixed on the side of the movable plate away from the second elastic element, and an insertion hole is provided on the slide plate to cooperate with the elastic telescopic rod.

[0013] Preferably, multiple elastic telescopic rods are provided and are not equidistant along the length of the moving plate.

[0014] Preferably, a push block is slidably connected inside the side plate to resist the movement of the movable plate, and the push block is fixedly connected to the pull rope.

[0015] Compared with the prior art, the present invention provides a shock-absorbing base for the engine room of a trailing suction hopper dredger, which has the following beneficial effects: 1. The shock-absorbing base of the trailing suction hopper dredger's engine room, through the lower clamping component and the transmission gearbox driving the upper clamping component, can simultaneously fix and limit the side and top of the generator set, ensuring the stability of the generator set installation and preventing the generator set from loosening due to vibration during operation. At the same time, it can automatically center the generator set on the base, ensuring the overall stress and vibration reduction effect of the base.

[0016] 2. The shock-absorbing base of the engine room of the trailing suction hopper dredger allows the sleeve and the lower clamping plate to slide elastically, so that when the lower clamping plate is in contact with the generator set while the upper clamping plate is not yet in contact with the generator set, the lower clamping assembly can continue to drive the upper clamping assembly to work until the upper clamping plate of the upper clamping assembly abuts against the top of the generator set and is limited.

[0017] 3. The shock-absorbing base of the trailing suction hopper dredger's engine room, by setting auxiliary balls on the lower clamping plate, allows the generator set to move by contacting the auxiliary balls when the upper and lower clamping components center and fix the generator set on the upper part of the base. This reduces the wear on the generator set during sliding and ensures the service life of the generator set. After the upper and lower clamping components have completed the fixing and limiting of the generator set, the L-shaped plate, together with the auxiliary balls, supports and limits the generator set, preventing the generator set from being squeezed and stressed by the auxiliary balls due to vibration during operation, which would cause spherical indentations on the generator set's outer shell.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A shock-absorbing base for the engine room of a trailing suction hopper dredger includes a base 1 fixed to the engine room by bolts. Several shock absorbers 2 are fixed on the top of the base 1. A mounting seat 3 is fixed on the top of the shock absorbers 2. The mounting seat 3 is provided with a lower clamping assembly for clamping a generator set 4 and an upper clamping assembly for clamping the upper side of the generator set 4. A transmission gearbox 5 is provided between the upper clamping assembly and the lower clamping assembly. The transmission gearbox 5 is fixed in the base 1. The lower clamping assembly is provided with auxiliary balls 6 that are slidably connected to the generator set 4 and an auxiliary support structure for supporting the generator set 4.

[0024] Specifically, during installation, generator set 4 is placed on mounting base 3. Then, the lower clamping assembly is controlled to move. The lower clamping assembly drives the upper clamping assembly through the transmission gearbox 5, which can simultaneously fix and limit the sides and top of generator set 4, ensuring the stability of generator set 4 installation and preventing generator set 4 from loosening due to vibration during operation. At the same time, it can automatically center generator set 4 on the top of base 1, ensuring the overall stress and vibration reduction effect of mounting base 3. By setting auxiliary ball bearings 6 on the lower clamping assembly, when the upper and lower clamping assemblies center and fix generator set 4 on the upper part of base 1, generator set 4 moves by contacting the auxiliary ball bearings 6, reducing the wear caused by the sliding of generator set 4 and ensuring the service life of generator set 4. The shock absorber 2 buffers and reduces the vibration generated by generator set 4 during operation.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, the lower clamping assembly includes a bidirectional screw 7 rotatably connected in the mounting base 3, the input shaft of the transmission gearbox 5 is connected to the bidirectional screw 7, a knob is provided at the end of the bidirectional screw 7, two sleeves 701 that move in opposite directions are threadedly connected to the bidirectional screw 7, a lower clamping plate 702 is provided on each sleeve 701, and a sliding groove 301 for sliding of the sleeve 701 is provided on the mounting base 3.

[0026] Furthermore, the lower clamping plate 702 includes a side plate 7021 disposed on the upper side of the sleeve 701 and a bottom plate 7022 fixedly connected to the side plate 7021, and the bottom plates 7022 of the lower clamping plates 702 on both sides of the mounting base 3 are slidably staggered, and auxiliary balls 6 are disposed on the side plate 7021 and the bottom plate 7022.

[0027] Specifically, by rotating the knob at the end of the bidirectional screw 7, the bidirectional screw 7 rotates within the mounting base 3. When the bidirectional screw 7 rotates, the sleeves 701 on both sides move relative to each other, causing the sleeves 701 to drive the lower clamping plate 702 to move, thereby causing the lower clamping plates 702 on both sides of the mounting base 3 to move relative to each other and center the generator set 4.

[0028] Reference Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As a preferred technical solution of the present invention, a connecting plate 8 is fixedly provided on the outer side of the side plate 7021, and a sliding plate 801 fixedly connected to the sleeve 701 is slidably connected inside the connecting plate 8. A first elastic element 802 is provided between the sliding plate 801 and the connecting plate 8.

[0029] Furthermore, the upper clamping assembly includes rotating rods 9 rotatably connected to both sides of the mounting base 3. Each rotating rod 9 is fixed with an upper clamping plate 901 that moves against the generator set 4. The output shaft of the transmission gearbox 5 is connected to the rotating rod 9.

[0030] Specifically, the upper clamping assembly moves along with the lower clamping assembly under the action of the transmission gearbox 5. That is, when the bidirectional screw 7 rotates, it drives the rotating rod 9 to rotate through the gear meshing in the transmission gearbox 5. When the rotating rod 9 rotates, it drives the upper clamping plate 901 to flip, so that the upper clamping plate 901 presses down and limits the top side of the generator set 4. By elastically sliding the sleeve 701 and the lower clamping plate 702, the lower clamping plate 702 can clamp and contact the generator set 4 while the upper clamping plate 901 has not yet clamped and contacted the generator set 4. In order to ensure that the rotating rod 9 continues to rotate, the sleeve 701 continues to move along the axial direction of the bidirectional screw 7 of the lower clamping assembly, while the lower clamping plate 702 maintains the current clamping positioning position, so that the upper clamping assembly continues to work until the upper clamping plate 901 of the upper clamping assembly abuts and limits the top of the generator set 4.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the auxiliary support structure includes an elastic telescopic tube 10 fixed in the lower clamping plate 702. The elastic telescopic tube 10 is inclined to the side plate 7021 and the bottom plate 7022. One end of the elastic telescopic tube 10 is fixed with an L-shaped plate 11 that slides in the lower clamping plate 702.

[0032] Furthermore, the auxiliary support structure also includes a force-bearing block 12 slidably connected within the upper clamping plate 901. The upper clamping plate 901 has an active groove 13 for sliding the force-bearing block 12. An elastic telescopic rod 131 is also provided between the inner wall of the active groove 13 and the force-bearing block 12. A pull rope 121 is fixed on the force-bearing block 12. The end of the pull rope 121 away from the force-bearing block 12 passes through the upper clamping plate 901, the mounting base 3, the L-shaped plate 11, and the lower clamping plate 702 in sequence and is connected to the telescopic end of the elastic telescopic tube 10.

[0033] Furthermore, a groove 14 is provided in the side plate 7021, and a movable plate 141 is slidably connected in the groove 14. A second elastic element 142 is provided between the movable plate 141 and the inner wall of the groove 14. An elastic telescopic rod 143 is fixed on the side of the movable plate 141 away from the second elastic element 142. A socket 8011 that cooperates with the elastic telescopic rod 143 is provided on the slide plate 801.

[0034] Furthermore, a push block 15 is slidably connected inside the side plate 7021 to move against the movable plate 141, and the push block 15 is fixedly connected to the pull rope 121.

[0035] Specifically, after the two lower clamping plates 702 clamp and limit the sides of the generator set 4, the two upper clamping plates 901 then press down and limit the top side of the generator set 4, achieving rapid centering and positioning of the generator set 4. This ensures that the generator set 4 applies force evenly to the multiple shock absorbers 2 when it vibrates, thus ensuring the overall vibration damping effect of the base. Before the upper clamping plates 901 abut against the generator set 4, the force-bearing block 12 abuts against the generator set 4 to receive force, the elastic telescopic rod 131 is compressed, and the force-bearing block 12 slides into the movable groove 13. When the force-bearing block 12 moves, it applies tension to the pull rope 121, which pulls the elastic telescopic tube 10 at the other end, causing the elastic telescopic tube 10 to be stretched and pushing the L-shaped plate 11 along the elastic telescopic tube. The L-shaped plate 11 moves axially, causing it to abut against the generator set 4, which is in contact with the auxiliary ball bearing 6 at this time. The L-shaped plate 11, together with the auxiliary ball bearing 6, supports and limits the generator set 4, preventing the generator set 4 from being squeezed and stressed by the auxiliary ball bearing 6 due to vibration during operation, which would cause a spherical indentation on the outer shell of the generator set 4. When the pull rope 121 is pulled, the pull rope 121 drives the push block 15 to apply downward pressure to the moving plate 141, causing the moving plate 141 to drive the elastic telescopic rod 143 to move downward. The elastic telescopic rod 143 is inserted into the insertion hole 8011 of the slide plate 801, limiting the position between the sleeve 701 and the lower clamping plate 702, thereby ensuring the clamping and limiting state of the lower clamping plate 702 on the side of the generator set 4.

[0036] Reference Figure 6 As a preferred technical solution of the present invention, multiple elastic telescopic rods 143 are provided and are unequally spaced along the length direction of the moving plate 141. Specifically, by providing multiple elastic telescopic rods 143 at unequal intervals on the moving plate 141, it can be ensured that at least one elastic telescopic rod 143 is always connected to the insertion hole 8011, and the remaining elastic telescopic rods 143 that are not connected to the insertion hole 8011 automatically retract when they come into contact with the sliding plate 801.

[0037] Working principle: When installing generator set 4, it is placed on the two lower clamping plates 702 on the upper side of the mounting base 3. By rotating the knob at the end of the double-acting screw 7, the double-acting screw 7 is rotated in the mounting base 3. When the double-acting screw 7 rotates, the sleeves 701 on both sides move relative to each other, causing the sleeves 701 to drive the lower clamping plates 702 to move, thereby causing the lower clamping plates 702 on both sides of the mounting base 3 to move relative to each other and center the generator set 4. The upper clamping assembly moves with the lower clamping assembly under the action of the transmission gearbox 5. That is, when the bidirectional screw 7 rotates, it drives the rotating rod 9 to rotate through the gear meshing in the transmission gearbox 5. When the rotating rod 9 rotates, it drives the upper clamping plate 901 to flip, so that the upper clamping plate 901 presses down and limits the top side of the generator set 4. After the two lower clamping plates 702 clamp and limit the generator set 4 on both sides, the two upper clamping plates 901 then press down and limit the top side of the generator set 4 and center it. When the upper clamping plates 901 clamp the generator set 4 in the center, the generator set 4 slides on the auxiliary balls 6 on the side and bottom of the lower clamping plates 702. Before the upper clamping plate 901 abuts against the generator set 4, the force-bearing block 12 abuts against the generator set 4 to receive force, the elastic telescopic rod 131 is compressed, and the force-bearing block 12 slides into the movable groove 13. When the force-bearing block 12 moves, it applies a pulling force to the pull rope 121, and the pull rope 121 pulls the elastic telescopic tube 10 at the other end, causing the elastic telescopic tube 10 to be stretched and pushing the L-shaped plate 11 to move along the axial direction of the elastic telescopic tube 10, so that the L-shaped plate 11 abuts against the generator set 4 which is in contact with the auxiliary ball 6 at this time. The L-shaped plate 11, in conjunction with the auxiliary ball 6, supports the generator set 4. The support limit prevents the generator set 4 from being squeezed and stressed by the auxiliary ball bearings 6 due to vibration during operation, which could cause a spherical indentation on the outer shell of the generator set 4. When the pull rope 121 is pulled, the pull rope 121 drives the push block 15 to apply downward pressure to the moving plate 141, causing the moving plate 141 to move the elastic telescopic rod 143 downward. The elastic telescopic rod 143 is inserted into the insertion hole 8011 of the slide plate 801, limiting the position between the sleeve 701 and the lower clamping plate 702, thereby ensuring the clamping and limiting state of the lower clamping plate 702 on the side of the generator set 4.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
