Description

Technical Field

[0001] This utility model relates to the technical field of connection buffer devices for engines, and in particular to a connection buffer device for industrial gas engines. Background Technology

[0002] The core processes of a gas turbine engine mainly consist of two parts: the mixing process and the combustion process. The purpose of both core processes is to ensure that the combustion process is efficient and complete. Throughout the entire process, whether it is the mixing or combustion process, the engine itself will vibrate. If rigid connections are used, the vibration will inevitably be transmitted to other parts. Nowadays, various damping devices are generally used to reduce the impact of engine vibration on the overall vibration.

[0003] A search revealed Chinese Patent Publication No. CN108638828A, which discloses a bus engine bracket, including a base frame, a buffer pad, a vertical frame, a first connecting frame, and a second connecting frame. The vertical frame is located at the upper end of the base frame, and the upper end of the vertical frame is connected to the first connecting frame. The front of the first connecting frame has an elongated opening, through which a first screw is slidably connected. While this technical solution effectively prevents the bracket assembly from cracking and breaking due to expansion caused by high temperatures, it cannot effectively decompose the vibration energy generated by the engine during operation, relying solely on the shock-absorbing pad. Furthermore, the buffer pad is prone to plastic deformation under long-term unidirectional impact, leading to a rapid decline in its buffering performance over time. This significantly reduces the service life of the engine and external mechanisms due to vibration. Therefore, a connecting buffer device for industrial gas engines is provided to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a connecting buffer device for industrial gas engines, which effectively buffers and reduces vibrations of the gas engine during use, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connecting buffer device for an industrial gas engine, comprising: a mounting box, four sets of guide columns fixedly connected to the inner side of the mounting box, an upper mounting plate provided on the upper side of the inner side of the mounting box, multiple sets of heat dissipation mounting through holes opened on the inner side of the upper mounting plate, a limit screw provided above each set of guide columns, several sets of shock absorption and buffer mechanisms installed on the bottom wall of the inner side of the mounting box, and an air intake fan embedded in the inner side of the mounting box.

[0006] As a further embodiment of this utility model: each set of shock-absorbing and buffering mechanisms includes two sets of side rotating bases, a first damping rod is rotatably connected to the inner side of the side rotating base, a first support spring is sleeved on the outer side of the first damping rod, a second damping rod is arranged between the two sets of side rotating bases, a second support spring is sleeved on the outer side of the second damping rod, a middle double-sided rotating seat is fixedly connected to the movable end of the second damping rod, and an upper support platform is fixedly connected above the middle double-sided rotating seat.

[0009] As a further improvement of this utility model, each set of guide posts is provided with a screw hole that matches the limiting screw, so as to prevent the upper mounting plate from detaching from the four sets of guide posts.

[0010] As a further improvement of this utility model, the two ends of the first support spring are respectively fixedly connected to the two ends of the first damping rod.

[0011] As a further embodiment of this utility model: the lower part of the second damping rod is fixedly connected to the lower bottom wall of the mounting box, and the two ends of the second support spring are respectively fixedly connected to the lower part of the middle double-sided rotating seat and the lower bottom wall of the mounting box.

[0012] As a further improvement of this utility model, the two ends of the bilateral rotating seat are respectively rotatably connected to the movable ends of the two sets of first damping rods in each set of shock absorption and buffer mechanisms.

[0013] As a further improvement of this utility model: when the limiting screw is tightly connected to the screw hole above the guide post, the upper support platform is exactly in close contact with the bottom of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the linkage design of the first damping rod and the second damping rod transforms the vertical vibration of the engine into a composite motion of axial compression and lateral tension or compression, thereby achieving three-dimensional vibration energy dispersion. The rotation linkage mechanism of the double-sided rotating seat effectively avoids unidirectional impact overload and significantly reduces the transmission of vibration to the engine and external frame.

[0016] 2. In this utility model, the intake fan and multiple sets of heat dissipation mounting holes form a through-type forced air cooling system, which directly dissipates heat from the high-heat area at the bottom of the engine. The matrix layout of the holes is adapted to the mounting holes of engines of different sizes, achieving the fixed function while taking into account the versatility of the airflow channel and improving the heat dissipation efficiency.

The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 4 In this embodiment of the present invention, a connecting buffer device for an industrial gas engine includes: a mounting box 1, four sets of guide posts 2 fixedly connected to the inner side of the mounting box 1, an upper mounting plate 3 provided on the upper inner side of the mounting box 1, four sets of guide through holes adapted to the guide posts 2 on the inner side of the upper mounting plate 3, and multiple sets of heat dissipation mounting through holes 4 on the inner side of the upper mounting plate 3. The opening position of the heat dissipation mounting through holes 4 is adapted to various sizes of industrial gas engine fixing holes, and a screw can be used to pass through the bottom of the heat dissipation mounting through holes 4 and the fixing holes of the industrial gas engine and be threaded to a nut. The engine is fixed in place. Each set of guide posts 2 is provided with a limit screw 5 above it. Each set of guide posts 2 is provided with a screw hole that matches the limit screw 5. This can prevent the upper mounting plate 3 from detaching from the four sets of guide posts 2. When the limit screw 5 is removed, the upper mounting plate 3 can be removed to fix the industrial gas engine on it. Several sets of shock absorption and buffer mechanisms 6 are installed on the bottom wall of the mounting box 1. An air intake fan 7 is embedded in the inner side of the mounting box 1. Air is drawn in from both sides of the mounting box 1 and blown out from the heat dissipation mounting hole 4, thereby cooling the industrial gas engine.

[0025] When the industrial gas engine is running, the vibration it generates is transmitted to the upper mounting plate 3 through the fixing screw. At this time, the cooperation between the guide post 2 and the guide through hole keeps the upper mounting plate 3 sliding vertically. The four sets of guide posts 2 form a rectangular constraint frame to prevent lateral displacement. The threaded connection of the limiting screw 5 at the top of the guide post 2 not only limits the upper displacement limit of the upper mounting plate 3, but also allows the engine to be installed as a whole after disassembly. The shock absorption and buffer mechanism 6 absorbs the vibration energy transmitted by the upper mounting plate 3 through the elastic support. At the same time, the airflow generated by the intake fan 7 forms a through air duct through the heat dissipation mounting through hole 4 to remove the heat from the bottom of the engine. The layout of multiple sets of heat dissipation mounting through holes 4 ensures heat dissipation coverage for engines of different sizes.

[0026] Each shock absorption and buffer mechanism 6 includes two sets of rotating bases 61. A first damping rod 62 is rotatably connected to the inner side of each rotating base 61. A first support spring 63 is sleeved on the outer side of the first damping rod 62. The two ends of the first support spring 63 are fixedly connected to the two ends of the first damping rod 62, respectively. A second damping rod 64 is provided between the two sets of rotating bases 61. A second support spring 65 is sleeved on the outer side of the second damping rod 64. A middle double-sided rotating seat 66 is fixedly connected to the movable end of the second damping rod 64. The lower part of the damping rod 64 is fixedly connected to the lower bottom wall of the mounting box 1. The two ends of the second support spring 65 are fixedly connected to the lower part of the middle double-sided rotating seat 66 and the lower bottom wall of the mounting box 1, respectively. The upper support platform 67 is fixedly connected above the middle double-sided rotating seat 66. The two ends of the middle double-sided rotating seat 66 are rotatably connected to the movable ends of the two sets of first damping rods 62 in each set of shock absorption and buffer mechanism 6. When the limit screw 5 is tightly connected to the screw hole above the guide post 2, the upper support platform 67 is just close to the lower part of the upper mounting slide plate 3.

[0027] When vibration is transmitted to the damping mechanism 6, the vertical vibration of the upper mounting plate 3 forces the upper support platform 67 to press down on the middle double-sided rotating seat 66. At this time, the second damping rod 64 and the second support spring 65 generate axial compression damping, consuming longitudinal vibration energy. Simultaneously, the descent of the middle double-sided rotating seat 66 drives the two sets of first damping rods 62 to rotate around the side rotating base 61. The first support spring 63 is stretched or compressed during rotation, forming a lateral buffer. The combined motion of the first damping rod 62 and the second damping rod 64 converts unidirectional vibration into multidirectional energy dissipation. The close contact between the upper support platform 67 and the upper mounting plate 3 forms preload, increasing the initial stiffness of the damping mechanism.

[0028] The working principle of this utility model is as follows: The operator first places the industrial gas engine on the surface of the upper mounting plate 3, aligns it with the engine fixing hole through the heat dissipation mounting through hole 4, and uses a screw to pass through the through hole to complete the mechanical locking. At this time, the limiting screw 5 has not yet been screwed into the screw hole at the top of the guide column 2. The upper mounting plate 3 can be installed along the four sets of guide columns 2. Tighten the limiting screw 5 so that the upper support platform 67 and the upper mounting plate 3 form a pre-pressure contact.

[0029] The vertical vibration generated during engine operation is transmitted to the upper mounting plate 3 through the fixing screw. The sliding fit between the guide post 2 and the guide through hole guides the vibration to be transmitted in the vertical direction. At this time, the upper mounting plate 3 presses down on the upper support platform 67, forcing the middle double-sided rotating seat 66 to compress the second damping rod 64 and the second support spring 65. The vertical vibration energy is consumed through axial damping. The descent of the middle double-sided rotating seat 66 synchronously drives the two sets of first damping rods 62 to rotate around the side rotating base 61, causing the first support spring 63 to undergo tensile or compressive deformation, converting the lateral vibration into spring deformation energy. The rotational motion of the first damping rod 62 and the linear motion of the second damping rod 64 form a spatial linkage, decomposing the single-direction impact into three-dimensional energy dissipation.

[0030] The intake fan 7 operates continuously during engine operation. External cold air is drawn in from both sides of the mounting box 1, passes around the shock absorption mechanism 6, and is blown to the bottom of the engine through the directional air duct formed by the heat dissipation mounting holes 4. The matrix layout of multiple sets of holes ensures that the heat source areas of engines of different sizes can be covered by airflow, realizing the simultaneous functions of vibration absorption and heat dissipation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
