Description

Technical Field

[0001] This invention relates to the field of ship testing equipment technology, and in particular to a dynamometer mounting base. Background Technology

[0002] A dynamometer is a device used to measure the output torque or drive torque of machinery. It is primarily used to determine the shaft power characteristics of machines such as generators, electric motors, internal combustion engines, gas turbines, or pumps. Dynamometers are typically mounted on a ground rail using a metal stool.

[0003] During the production and commissioning of marine diesel engines, in order to minimize the damage to engine components and the impact of engine vibration caused by shaft misalignment, the installation and adjustment of the hydraulic dynamometer are necessary. For small dynamometers, due to their light weight, adjustment after the dynamometer is placed on the iron stool is relatively easy. However, for dynamometers used for testing large-bore, low-speed marine diesel engines, which weigh anywhere from hundreds to tens of tons, adjusting their position after placement on the iron stool is relatively difficult. Typically, a dedicated adjustment device needs to be fabricated, and the fixing and arrangement of this device require careful design based on the dynamometer's initial position, making the process cumbersome and resulting in low efficiency in dynamometer installation and adjustment.

[0004] Therefore, there is an urgent need for a dynamometer mounting base to solve the above problems. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] This embodiment provides a dynamometer mounting base for placing a dynamometer. Figure 1 As shown, the dynamometer mounting base includes a support mechanism 1 and an adjustment mechanism 2.

[0044] Reference Figures 1-3The support mechanism 1 of the dynamometer mounting base is configured to be fixedly mounted on the ground rail 200. The support mechanism 1 includes a support surface on which the dynamometer base 100 is mounted. The support mechanism 1 provides a mounting position for the dynamometer and, being fixed to the ground rail 200, helps improve the stability of the dynamometer during testing. The adjustment mechanism 2 includes a horizontal adjustment component 21 and a vertical adjustment component 22. The horizontal adjustment component 21 is connected to a part of the support mechanism 1 and is located around the periphery of the dynamometer base 100, enabling adjustment of the dynamometer's position on the horizontal plane. The vertical adjustment component 22 is connected to another part of the support mechanism 1 and is located below the dynamometer base 100, enabling adjustment of the dynamometer's height. In other words, after the dynamometer is placed on the dynamometer mounting base, the horizontal adjustment component 21 and the vertical adjustment component 22 can directly adjust the position of the dynamometer in the horizontal and vertical directions without the need for additional special adjustment devices, effectively shortening the adjustment time of the dynamometer coupling and improving the adjustment efficiency after the dynamometer is placed.

[0045] Specifically, continue to refer to Figure 1 The support mechanism 1 includes a first support member 11 and a second support member 12. Two first support members 11 are provided, arranged parallel to each other and spaced apart. Each first support member 11 extends along a first direction, perpendicular to the extension direction of the ground rail 200. The second support member 12 is positioned between the two first support members 11. The second support member 12 extends along a second direction, parallel to the extension direction of the ground rail 200. The upper surface of the second support member 12 is flush with the upper surfaces of the two first support members 11; the plane containing the upper surfaces of the second support member 12 and the two first support members 11 is the support surface. A horizontal adjustment component 21 is installed on the first support member 11, and a vertical adjustment component 22 is installed on the second support member 12. The first and second support members 11 form the support frame for the dynamometer mounting base, ensuring the stability of the dynamometer after it is seated.

[0046] More specifically, such as Figure 1 As shown, there are two second support members 12, which are parallel and spaced apart. Vertical adjustment components 22 are symmetrically connected to both ends of each second support member 12. Two first support members 11 and two second support members 12 are each provided, forming a rectangular support surface that corresponds to the four sides of the dynamometer base 100, ensuring the dynamometer is under balanced force.

[0047] Optionally, such as Figure 1-4As shown, the horizontal adjustment assembly 21 includes a first horizontal adjustment member 211 and a second horizontal adjustment member 212. Two sets of first horizontal adjustment members 211 are provided, spaced apart along a second direction. Two members in each set are symmetrically connected to both sides of the support mechanism 1 along a first direction. Correspondingly, two sets of second horizontal adjustment members 212 are also provided. Two sets of second horizontal adjustment members 212 are spaced apart along a first direction, and two members in each set are symmetrically connected to both sides of the support mechanism 1 along a second direction. In this embodiment, four first horizontal adjustment members 211 and four second horizontal adjustment members 212 are provided. The four first horizontal adjustment members 211 are respectively installed at both ends of the two first support members 11, and the four second horizontal adjustment members 212 are respectively installed on opposite sides of the two first support members 11. After the dynamometer is seated, the four first horizontal adjustment members 211 and the four second horizontal adjustment members 212 are located on the outer sides of the four apex corners of the dynamometer base 100.

[0048] Simultaneously, the first horizontal adjustment member 211 can adjust the position of the dynamometer base 100 in the first direction, and the second horizontal adjustment member 212 can adjust the position of the dynamometer base 100 in the second direction, with the first direction perpendicular to the second direction. Based on the above position settings, the four first horizontal adjustment members 211 and the four second horizontal adjustment members 212 can realize the position movement of the dynamometer base 100 on the horizontal plane and its micro-rotation within the horizontal plane, thereby achieving shaft alignment adjustment between the dynamometer and the diesel engine.

[0049] Specifically, refer to Figure 4 The first horizontal adjustment member 211 includes a first support plate 2111, a first pad plate 2112, and a first adjustment member (not shown). The first support plate 2111 includes a second support portion and a second mounting portion arranged vertically. The second mounting portion is connected to the support mechanism 1, and a plurality of first pad plates 2112 are sandwiched between the second mounting portion and the support mechanism 1. The second support portion is perpendicular to the support surface and is located above the support surface. One end of the first adjustment member is connected to the second support portion, and the other end abuts against the side of the dynamometer base 100. That is, by changing the number of first pad plates 2112, the distance between the first support plate 2111 and the dynamometer base 100 is adjusted, thereby adjusting the distance between the second support portion and the side of the dynamometer base 100, i.e., adjusting the installation distance of the first adjustment member. The first adjustment member can drive the dynamometer base 100 to move in a first direction. Exemplarily, the first adjustment member can be a hydraulic lifter commonly used in the prior art, preferably a hydraulic jack.

[0050] Similarly, the second horizontal adjustment member 212 includes a second support plate 2121, a second pad plate 2122, and a second adjustment member (not shown). The second support plate 2121 includes a third support portion and a third mounting portion arranged vertically. The third mounting portion is connected to the support mechanism 1, and a plurality of second pad plates 2122 are sandwiched between the third mounting portion and the support mechanism 1. The third support portion is perpendicular to the support surface and is located above the support surface. One end of the second adjustment member is connected to the third support portion, and the other end abuts against the side of the dynamometer base 100. That is, by changing the number of second pad plates 2122, the distance between the second support plate 2121 and the dynamometer base 100 is adjusted, thereby adjusting the distance between the third support portion and the side of the dynamometer base 100, i.e., adjusting the installation distance of the second adjustment member. The second adjustment member can drive the dynamometer base 100 to move in the second direction. Exemplarily, the second adjustment member can also be a hydraulic lifter commonly used in the prior art, preferably a hydraulic jack.

[0051] For more details, please refer to [link / reference]. Figure 4 The first leveling member 211 further includes a first reinforcing structure 2113. The first reinforcing structure 2113 is disposed on the side of the first support plate 2111 facing away from the dynamometer base 100. The first reinforcing structure 2113 is a group of intersecting reinforcing ribs used to improve the structural strength of the first support plate 2111. Correspondingly, the second leveling member 212 also includes a second reinforcing structure 2123. The second reinforcing structure 2123 is disposed on the side of the second support plate 2121 facing away from the dynamometer base 100. The second reinforcing structure 2123 is also a group of intersecting reinforcing ribs used to improve the structural strength of the second support plate 2121. In this embodiment, the specific structure of the first reinforcing structure 2113 and the second reinforcing structure 2123 is such that it does not affect the installation of the first support plate 2111 and the second support, while providing support to the second support portion and the second mounting portion or the third support portion and the third mounting portion from the back, ensuring the structural strength of the first leveling member 211 and the second leveling member 212.

[0052] Preferably, in this embodiment, the first reinforcing structure 2113 and the first support plate 2111 are welded together, and the second reinforcing structure 2123 and the second support plate 2121 are welded together to improve the overall structure and further improve the structural strength of the first horizontal adjustment member 211 and the second horizontal adjustment member 212.

[0053] More specifically, the first leveling member 211 is detachably connected to the first support member 11. In this embodiment, a first through hole is formed on the second mounting portion, a first through hole is formed at a corresponding position on the first pad 2112, and a first mounting hole is formed at a corresponding position on the end of the first support member 11. A first mounting bolt passes through the first through hole and the first through hole in sequence and is screwed into the first mounting hole, thereby achieving a reliable connection between the first support plate 2111 and the first support member 11. Correspondingly, the second leveling member 212 is detachably connected to the first support member 11. The connection method between the second leveling member 212 and the first support member 11 is basically the same as the connection method between the first leveling member 211 and the first support member 11. Specifically, a second through hole is formed on the third mounting portion, a second through hole is formed at a corresponding position on the second pad 2122, and a second mounting hole is formed at a corresponding position on the side of the first support member 11. A second mounting bolt passes through the second through hole and the second through hole in sequence and is screwed into the second mounting hole, thereby achieving a reliable connection between the second support plate 2121 and the first support member 11. After the dynamometer is adjusted, the first and second mounting bolts can be turned in the opposite direction to disassemble the first leveling component 211 and the second leveling component 212. The operation is simple and saves time.

[0054] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the vertical adjustment assembly 22 includes a first bracket 221 and a first height adjustment component (not shown). The first bracket 221 is tunably connected to the side end face of the second support member 12. One end of the first height adjustment component is connected to the first bracket 221, and the other end abuts against the bottom surface of the dynamometer base 100. The first height adjustment component can drive the dynamometer base 100 to move up and down. In this embodiment, four vertical adjustment assemblies 22 are provided, and the four vertical adjustment assemblies 22 are respectively connected to the two ends of the two second support members 12. That is, the four vertical adjustment assemblies 22 can lift the dynamometer base 100 from the bottom, thereby realizing the adjustment of the dynamometer height. For example, the first height adjustment component can be a hydraulic lifter commonly used in the prior art, preferably a hydraulic jack.

[0055] Specifically, see Figure 5The first bracket 221 includes a first mounting portion 2211 and a first support portion 2212 connected at an angle. The first mounting portion 2211 is fitted to the side end face of the second support member 12 and its height is adjustable. The first support portion 2212 is parallel to the upper surface of the second support member 12, and a first height adjustment member is connected to the first support portion 2212. In this embodiment, the first mounting portion 2211 and the first support portion 2212 are vertically connected. The side of the second support member 12 has multiple third mounting holes along its height direction, and the first mounting portion 2211 has corresponding third through holes. A second mounting bolt passes through the third through holes and is screwed into any one of the third mounting holes to achieve a reliable connection between the first mounting portion 2211 and the second support member 12. By changing the position of the third mounting holes connected to the first mounting portion 2211, the distance between the first support portion 2212 and the bottom surface of the dynamometer base 100 can be adjusted, that is, the installation spacing of the first height adjustment member can be adjusted.

[0056] More specifically, the first bracket 221 also includes a third reinforcing structure. This third reinforcing structure connects the first mounting portion 2211 and the first support portion 2212. In this embodiment, the third reinforcing structure is a reinforcing rib, which is vertically connected to the first mounting portion 2211 and the first support portion 2212. There can be one reinforcing rib or multiple reinforcing ribs spaced apart, as long as they do not affect the connection between the first mounting portion 2211 and the second support member 12. The specific number and arrangement can be determined according to the actual situation, and this embodiment does not impose any limitations. This third reinforcing structure improves the connection strength between the first mounting portion 2211 and the first support portion 2212, and enhances the stress on the first support portion 2212, ensuring the stability of the dynamometer base 100 when the first height adjustment member lifts it.

[0057] More specifically, in this embodiment, the third reinforcing structure is welded to the first mounting part 2211 and the first support part 2212 respectively, so as to improve the structural integrity of the first bracket 221 and ensure the structural strength of the first bracket 221.

[0058] Understandably, in this embodiment, when adjusting the shaft alignment of the dynamometer and the diesel engine, the dynamometer mounting base is first firmly fixed to the ground rail 200 with bolts. At this time, the support mechanism 1 of the dynamometer mounting base cannot move. Then, the dynamometer is hoisted to a suitable position on the dynamometer mounting base. Finally, the dynamometer is finely adjusted in various directions by the adjustment mechanism 2 of the dynamometer mounting base to meet the installation accuracy requirements of the dynamometer spindle, reduce the fine adjustment time of the dynamometer, and improve the coupling efficiency of the dynamometer.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
