Description

Technical Field

[0001] The invention relates to the technical field of diesel engine vibration reduction, in particular to an adjustable diesel engine vibration reduction support device. Background Art

[0002] As a widely used power equipment, diesel engines play a core role in multiple industrial fields and critical infrastructure. However, during the operation of diesel engines, mechanical vibration and load fluctuations often produce large vibrations and noise. These vibrations not only affect the service life of the generator, but may also interfere with surrounding equipment and the environment. Therefore, how to effectively reduce and control the vibration problem in the operation of diesel engines has become the key to ensuring the long-term and stable operation of the equipment.

[0003] Traditional diesel engine shock-absorbing support devices mostly use simple spring shock absorbers or rubber shock-absorbing pads. Although these devices can reduce vibration transmission to a certain extent, they often have problems such as unstable shock absorption effect and poor adaptability. Especially in the case of large load fluctuations, traditional shock-absorbing devices are often difficult to cope with, resulting in increased vibration amplitude and damage to the equipment.

[0004] In recent years, with the continuous progress of material science and shock absorption technology, adjustable shock absorption support devices have gradually become a hot topic of research. Adjustable shock absorption support devices can not only be flexibly adjusted according to the specific needs of the equipment, but also can achieve ideal shock absorption effects under different working conditions. For example, the ZTF adjustable damping spring shock absorber is designed based on the joint working principle of spring and damper. The spring absorbs vibration energy and the damper dissipates excess vibration energy to achieve a dual shock absorption effect. In addition, the shock absorber also has an adjustable damping function, making it more adaptable to various complex working environments.

[0005] However, the existing adjustable shock-absorbing support devices still have some shortcomings. For example, some devices have complex structures and are difficult to install and maintain; although some devices have adjustment functions, the adjustment range is limited and it is difficult to meet the diverse needs of different equipment. Therefore, it is particularly important to develop an adjustable diesel engine shock-absorbing support device with a simple structure, convenient installation and a wide adjustment range. Summary of the invention

[0006] The object of the present invention is to provide an adjustable diesel engine shock absorbing support device to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an adjustable diesel engine shock absorbing support device, comprising a diesel engine, a base is arranged under the diesel engine, a plurality of support components are arranged on the top of the base, the support components include a first base fixedly mounted on the top surface of the base, a first groove is arranged on the top of the first base, a lifting track is arranged on the inner wall of the first groove, a first support rod is slidably connected to the lifting track, and the top of the first support rod matches the specifications of the support groove at the bottom of the diesel engine.

[0008] According to the above technical solution, the diesel engine includes two groups of engines, and a second base fixedly installed on the top of the base is arranged between the two engines. A plurality of metal rods are fixedly installed on the top of the second base, and the plurality of metal rods are commonly connected to a support plate. Second support rods are extended from both side walls of the support plate, and the second support rods are connected to the engines. The engines are supported at multiple angles by the first support rods and the second support rods.

[0009] According to the above technical solution, a telescopic shell is arranged on the top of the first support rod, and a high-strength alloy spring is arranged inside the telescopic shell.

[0010] According to the above technical solution, the high-strength alloy spring includes a third base fixed on the top of the first support rod and located in the inner area of ​​the telescopic shell, a lower reinforcement plate is fixedly installed on the top of the third base, an adjustable damper is installed in the top middle area of ​​the lower reinforcement plate, an upper reinforcement plate is fixedly installed on the top of the adjustable damper, and a spring wrapped around the outside of the adjustable damper is arranged between the lower reinforcement plate and the upper reinforcement plate.

[0011] According to the above technical solution, a lower extension plate is welded to one side of the lower reinforcement plate, a slot hole is set in the end area of ​​the lower extension plate, a bottom block is fixedly installed at the bottom of the lower extension plate, and a plurality of first positioners are evenly installed on the side walls of the bottom block from top to bottom.

[0012] According to the above technical solution, an upper extension plate welded to one side of the upper reinforcement plate is arranged in the vertical upper area of ​​the slot hole, an insertion rod is fixedly installed in the end area of ​​the upper extension plate, a second positioner is installed at the bottom of the insertion rod, and the first positioner matches the second positioner.

[0013] According to the above technical solution, different types of support and shock absorption forms for the engine are achieved by remotely adjusting the damping coefficient of the adjustable damper. The PLC system matched with the engine sets the operating power of the engine to P, which is divided into 12 levels from P1 to P12. P1 indicates that the operating power of the engine is the smallest, and P12 indicates that the operating power of the engine is the largest. The PLC system sets the damping coefficient of the adjustable damper to M, which is divided into 12 levels from M1 to M12. M1 indicates that the damping coefficient of the adjustable damper is the smallest, and M12 indicates that the damping coefficient of the adjustable damper is the largest. Accordingly, P1-P12 corresponds to M1-M12.

[0014] According to the above technical solution, the damping coefficient of the adjustable damper after adjustment is detected by sensing the second positioner with the first positioner at the corresponding horizontal position, so as to ensure that the adjustment of the adjustable damper is always correct.

[0015] According to the above technical solution, when the operating power of one engine is at the P12 level, the second support rod on one side of the other engine can be driven to retract, so that this engine is supported only by the first support rod.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by providing a high-strength alloy spring, the adjustable damper cooperates with the spring to flexibly adjust the shock absorption effect according to the actual working state and environmental requirements of the diesel engine. For example, when the load is large, the damping coefficient can be increased to reduce the propagation of vibration; when running under light load, the damping can be appropriately reduced to improve the stability of the equipment.

Specifically, the gears installed at the output end of each group of engines 8 are inconsistent, and then the matching external structures are different. The external structure is used to receive the energy supply from the engine 8. The diesel engine 1 in this embodiment can be connected to two different external structures at the same time, or only one external structure can be connected to the diesel engine 1 in this embodiment. The number of external structures to be connected is selected according to production requirements to achieve the purpose of operating a single external structure or multiple external structures. A second base 9 fixedly mounted on the top of the base 2 is arranged between the two engines 8, and a plurality of metal rods 10 are fixedly mounted on the top of the second base 9, and the plurality of metal rods 10 are connected to a support plate 11 together, and second support rods 12 are extended from both side walls of the support plate 11, and the second support rods 12 are connected to the engine 8, and the engine 8 is supported at multiple angles by the first support rods 7 and the second support rods 12, and the number of the first support rods 7 and the second support rods 12 is small, and the space around the engine 8 is small, so that the engine 8 can be supported and fixed and the heat dissipation efficiency of the engine 8 can be improved; A telescopic housing 13 is arranged on the top of the first support rod 7. The telescopic housing 13 is assembled by multi-layer circular shells and can be raised and lowered by manual or electric control. In this embodiment, the telescopic housing 13 is remotely controlled by electric control. A high-strength alloy spring 14 is arranged on the inner side of the telescopic housing 13. The high-strength alloy spring 14 has excellent elasticity and durability, is responsible for absorbing vibration energy, and alleviates the mechanical impact from the diesel engine. The high-strength alloy spring 14 includes a third base 15 fixed to the top of the first support rod 7 and located in the inner area of ​​the telescopic housing 13. The top of the third base 15 is fixedly installed A lower reinforcement plate 16 is provided, an adjustable damper 17 is installed in the middle area of ​​the top of the lower reinforcement plate 16, an upper reinforcement plate 18 is fixedly installed on the top of the adjustable damper 17, a spring 19 is arranged between the lower reinforcement plate 16 and the upper reinforcement plate 18 and is wound around the outer side of the adjustable damper 17, and different types of support and shock absorption forms of the engine 8 are realized by remotely adjusting the damping coefficient of the adjustable damper 17, and the PLC system matched with the engine 8 sets the operating power of the engine 8 to P, which is divided into 12 levels from P1 to P12, where P1 indicates that the operating power of the engine 8 is the smallest, and P12 indicates that the operating power of the engine 8 is the largest. The PLC system sets the damping coefficient of the adjustable damper 17 to M, which is divided into 12 levels from M1 to M12. M1 indicates that the damping coefficient of the adjustable damper 17 is the smallest, and M12 indicates that the damping coefficient of the adjustable damper 17 is the largest. Correspondingly, P1-P12 corresponds to M1-M12. If the operating power of the engine 8 increases and the vibration frequency of the engine 8 increases, the damping coefficient of the corresponding adjustable damper 17 increases, thereby increasing the damping strength of the adjustable damper 17. By increasing the damping strength, the shock absorbing effect on the engine 8 is enhanced, and the supporting performance of the engine 8 can also be improved. If the engine 8 is always supported with a high-strength damping coefficient, the damping quality of the engine 8 will be low. This damping support mode will damage the engine 8 after a long period of operation. The spring 19 will deform with the adjustable damper 17, which also has the effect of damping the engine 8. The adjustable damper 17 and the spring 19 can flexibly adjust the damping effect according to the actual working state and environmental requirements of the diesel engine. For example, when the load is large, the damping coefficient can be increased to reduce the propagation of vibration; when running under light load, the damping can be appropriately reduced to improve the stability of the equipment. A lower extension plate 20 is welded to one side of the lower reinforcement plate 16, a slot hole 21 is set in the end area of ​​the lower extension plate 20, a bottom block 24 is fixedly installed at the bottom of the lower extension plate 20, and a plurality of first positioners 25 are evenly installed on the side wall of the bottom block 24 from top to bottom, an upper extension plate 22 welded to one side of the upper reinforcement plate 18 is set in the vertical upper area of ​​the slot hole 21, a plug rod 23 is fixedly installed in the end area of ​​the upper extension plate 22, and a second positioner 26 is installed at the bottom of the plug rod 23, the first positioner 25 matches the second positioner 26, and the plug rod 23 and the slot hole 21 are in the same A vertical line, the process of adjusting the damping coefficient of the adjustable damper 17 is that the adjustable damper 17 drives the upper reinforcement plate 18 to rise or fall, and then drives the insertion rod 23 to rise or fall. When the insertion rod 23 rises or falls, the second positioner 26 also rises and falls accordingly. The second positioner 26 senses the first positioner 25 at the corresponding horizontal position, and the damping coefficient after the adjustment of the adjustable damper 17 is detected to ensure that the adjustment of the adjustable damper 17 is always correct. If the adjustment of the adjustable damper 17 is found to have an error after the detection, the PLC system calls for manual inspection. This detection process ensures that the adjustable damper 17 maintains excellent performance in long-term use and extends its service life; The second support rod 12 is a telescopic rod, one end of which is fixed to the side wall of the support plate 11, and the other end is non-fixedly connected to the engine 8. When the operating power of one of the engines 8 is at the P12 level, the second support rod 12 on one side of the other engine 8 can be driven to retract, so that this engine 8 is supported only by the first support rod 7. The vibration frequency of the engine 8 reaching the P12 level is high. Separating the two engines 8 can reduce the vibration of the other engine 8, and also reduce the vibration of the engine 8 reaching the P12 level. If it is not the above situation, the second support rod 12 is driven again to extend and snap into the side groove of the corresponding engine 8; By providing the first support rod 7 and the second support rod 12 which are not fixedly connected to the engine 8 , various types of engines 8 can be matched, and the installation and removal of the engine 8 are also convenient.
