Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, in particular to a mounting structure of a gas generator set. Background Art

[0002] Gas-fired generator sets are power generation equipment that use gas as a power source and are widely used in industrial, commercial and residential electricity supply. Their main advantages include high energy utilization efficiency, fast startup, and relatively low environmental pollution. With the continuous global pursuit of clean energy and energy efficiency, gas-fired generator sets are playing an increasingly important role in the modern energy structure.

[0003] Currently, gas generator sets are usually fixed on a supporting base with bolts and nuts. However, during operation, gas generator sets will generate large mechanical vibrations due to high-speed operation and constant changes in load. These vibrations will cause the fixing nuts to gradually loosen. Once the nuts are loose, the structural components of the unit will loosen, misalign, or suffer more serious mechanical damage, thereby affecting the structural stability and operational safety of the entire generator set.

[0004] In view of this, the present invention proposes an installation structure of a gas generator set to solve the above problems. Summary of the invention

[0017] The beneficial effects of the present invention are:

[0018] (1) In the present invention, the ratchet and the rotating shaft are coaxially arranged with the rotating shaft as the rotating shaft, and the ratchet teeth limit the teeth of the ratchet wheel, so that the ratchet wheel can rotate freely in one direction, while the ratchet teeth prevent the ratchet wheel from rotating in the opposite direction, thereby preventing the nut from rotating in the opposite direction on the outside of the bolt, increasing the pre-tightening force of the nut on the bolt, and allowing the frame and the bearing plate to be stably installed together, thereby improving the structural stability and operating safety of the gas generator device.

The slider and the limit plate are coaxially arranged with bolts, and the limit plate drives the helical teeth to engage in the inside of the slot, and the bolts pass through the holes of the frame and are inserted into the slider, so that the frame and the load-bearing plate can be firmly connected, thereby increasing the stability and load-bearing capacity of the entire device.

[0020] (3) In the present invention, the threaded sleeve and the bolt are engaged through threads, which better disperses the pressure on the bolt and reduces the damage to the bolt caused by excessive local load. In addition, the threaded sleeve further enhances the overall stability of the entire rotating assembly, the bolt and the bolt. The sleeve block is arranged on the outside of the nut, making the installation and adjustment of the nut easier. The user does not need to directly operate the nut, but can adjust it by rotating the ratchet, which is particularly useful in environments with narrow space or inconvenient operation. The threads in the threaded sleeve are engaged with the threads of the bolt to protect the threads of the threaded sleeve from damage, extend the service life of the bolt, and also protect the threads of the bolt from being corroded by the external environment.

[0021] (4) The ratchet teeth are squeezed by the insertion rod to disengage them from the teeth of the ratchet wheel, thereby quickly releasing the lock of the ratchet teeth on the ratchet wheel, so that the insertion rod controls the release of the ratchet wheel to facilitate the separation of the nut and the bolt, and the user can easily adjust the distance of the nut engaging and tightening the bolt.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] Example 1

[0045] like Figures 1 to 3 ,as well as Fig. 9 , Fig. 9 and Fig.10 A mounting structure of a gas generator set of the present invention comprises a gas generator mechanism 1, the gas generator mechanism 1 comprises a gas generator device 110, and a frame 120 is fixedly installed on the outer side of the gas generator device 110, and a hole is opened inside the frame 120, and two groups of frames 120 are provided, and the two groups of frames 120 are fixedly installed at the bottom of the two outer side walls of the gas generator device 110, and a bearing frame 2 is provided at the bottom end of the frame 120, and the bearing frame 2 comprises a bearing plate 210, and the bearing plate 210 is fixedly installed at the bottom of the frame 120, and an I-beam 220 is fixedly installed at the bottom end of the bearing plate 210, and a sliding component 3 is provided inside the bearing plate 210, and a limit frame 4 is fixedly installed on the inner bottom of the frame 120, and a bolt 5 is inserted inside the limit frame 4, and a positioning component 6 is inserted inside the sliding component 3, and the positioning component 6 is sleeved on the outer side of the bolt 5, and a nut 7 is sleeved on the outer side of the bolt 5;

[0046] A fastening structure 8, which is sleeved on the outside of the nut 7 and is used to limit the position of the nut 7;

[0047] The fastening structure 8 includes a sleeve block 810 , and the sleeve block 810 is sleeved on the outside of the nut 7 , and a rotating component 820 is sleeved on the outside of the sleeve block 810 , and a one-way limiting component 830 is fixedly installed on the bottom end of the positioning component 6 .

[0048] When the device is working, the rotation direction of the sleeve block 810 is limited through the mechanism of the one-way limiting component 830, so that the sleeve block 810 rotates in the tightening direction but cannot rotate in the opposite direction. This can effectively prevent the bolt 5 from loosening by itself under the action of vibration or repeated stress, thereby increasing the safety and stability of the connection between the frame 120 and the supporting plate 210. The matching sleeve block 810 of the one-way limiting component 830 drives the nut 7 to engage with the bolt 5 through the thread, ensuring that the bolt 5 is tightened with an appropriate torque of the bolt 5, thereby helping to achieve an ideal preload force.

[0049] Example 2

[0050] like Figures 2 to 9As shown, on the basis of Example 1, the sliding assembly 3 includes a slide groove 310, and the slide groove 310 is opened inside the bearing plate 210, the top ends of the two inner side walls of the slide groove 310 are each provided with a limit groove 320, and the bottom ends of the two inner side walls of the slide groove 310 are each provided with a card groove 330, the positioning assembly 6 includes a slider 610, the inside of the slide groove 310 is each inserted with a slider 610, and the outer side wall of the slider 610 is fixedly installed with a limit block 620, the limit block 620 is slidably connected to the inside of the limit groove 320, and a limit plate 630 is sleeved on the outer side wall of the bolt 5, and the limit plate 630 is located below the slider 610, as shown in FIG. Figure 5 In the embodiment, the top of the limit plate 630 is fixedly mounted with a helical tooth 640, such as Figure 6 In the figure, a gasket 650 is sleeved on the outer wall of the bolt 5, and the gasket 650 is located at the bottom end of the limit plate 630, the bottom two sides of the slider 610 are arranged in an inclined surface, the inner diameter size of the limit groove 320 is matched with the inner diameter size of the limit block 620, the inner diameter size of the slot 330 is matched with the outer diameter size of the helical tooth 640, and the nut 7 is located directly below the gasket 650.

[0051] When the device is working, the slider 610 and the limit block 620 are respectively inserted into the slide groove 310 and the limit groove 320, and the slider 610 moves in the slide groove 310 and the limit groove 320 through the limit block 620 to just below the hole opened inside the frame 120, so that the bolt 5 can pass through the hole inside the supporting frame 2 and the inside of the slider 610. The gasket 650 and the limit plate 630 are squeezed by the nut 7, so that the limit plate 630 drives the helical teeth 640 to engage in the inside of the slot 330, and then the position of the slider 610 is in an engaged state, thereby firmly connecting the frame 120 and the supporting plate 210, thereby increasing the stability and bearing capacity of the entire device.

[0052] Example 3

[0053] like Figures 4 to 10As shown, on the basis of Example 1, the rotating assembly 820 includes a circular gear 821, and the circular gear 821 is fixedly installed on the outer side of the sleeve block 810, a threaded sleeve 822 is fixedly installed on the bottom end of the sleeve block 810, and the threaded sleeve 822 is meshed with the bolt 5 through threads, a rotating disk 823 is fixedly installed on the bottom end of the threaded sleeve 822, a rotating shaft 824 is inserted into the interior of the limiting plate 630, and a wide gear 825 is fixedly installed on the outer side of the rotating shaft 824, the inner diameter size of the sleeve block 810 is adapted to the outer diameter size of the nut 7, the circular gear 821 is meshed with the wide gear 825 through teeth, and the one-way limiting assembly 830 includes a vertical plate 831, The vertical plate 831 is fixedly installed on the bottom end of the limiting plate 630, and a U-shaped frame 832 is fixedly installed on the outer side of the vertical plate 831, a ratchet 833 is fixedly installed on the outer side of the rotating shaft 824, a hinge rod 834 is fixedly installed on the bottom end of the inner wall of the U-shaped frame 832, and a ratchet 835 is hinged on the outer side of the hinge rod 834, one end of the ratchet 835 is hinged to the hinge rod 834, a first spring 836 is fixedly installed on the outer side of the ratchet 835, and a fixed plate 837 is fixedly installed on the other end of the first spring 836, the bottom end of the fixed plate 837 is fixedly installed on the bottom of the inner wall of the U-shaped frame 832, and the other end of the ratchet 835 is engaged with the teeth of the ratchet 833.

[0054] When the device is working, the threaded sleeve 822 and the bolt 5 are meshed through the thread, so as to disperse the pressure on the outer thread of the bolt 5 and reduce the damage to the outer part of the thread of the bolt 5 caused by the excessive load on the local thread of the outer thread of the bolt 5. The rotating disk 823 drives the sleeve block 810 to be sleeved on the outer side of the nut 7 through the threaded sleeve 822 and the circular gear 821, so that the nut 7 is installed on the outer side of the bolt 5 more easily. The user rotates the rotating disk 823 to adjust the meshing position of the nut 7 on the outer side of the bolt 5, thereby improving the practicality of the operation of the bolt 5 and the nut 7 in a narrow space. At the same time, the thread in the threaded sleeve 822 is meshed with the thread of the bolt 5 to protect the nut 7. The thread of the sleeve 822 is not damaged, which extends the service life of the bolt 5, and the circular gear 821 is meshed with the wide gear 825 through the teeth. The ratchet 833 and the rotating shaft 824 are coaxially arranged with the rotating shaft 824, and the ratchet 835 limits the teeth of the ratchet 833, so that the ratchet 833 can rotate freely in one direction, and the ratchet 835 prevents the ratchet 833 from rotating in the opposite direction, thereby preventing the nut 7 from rotating in the opposite direction on the outside of the bolt 5, increasing the pre-tightening force of the nut 7 on the bolt 5, and allowing the frame 120 and the supporting plate 210 to be stably installed together, thereby improving the stability of the internal structure and operation safety of the entire gas generator device 110.

[0055] Example 4

[0056] like Fig. 9 and Fig.10As shown, on the basis of Example 1, the fastening structure 8 also includes an ejection component 840, and the ejection component 840 is inserted into the interior of the U-shaped frame 832, the ejection component 840 includes an insertion rod 841, and the insertion rod 841 is inserted into the interior of the U-shaped frame 832, a second spring 842 is sleeved on the outer side of the insertion rod 841, and a ejection block 843 is fixedly installed on the other end of the insertion rod 841, and the two ends of the second spring 842 are respectively fixedly installed on the inner wall of the U-shaped frame 832 and the outer side of the ejection block 843, the second spring 842 is in an elastic static state, the other end of the ratchet 835 is arranged in an inclined surface, and the outer side of the ejection block 843 conflicts with the outer side of the ratchet 835.

[0057] When the device is working, the insertion rod 841 drives the top block 843 to squeeze the ratchet 835, and the ratchet 835 rotates around the hinge rod 834 to make the ratchet 835 disengage from the teeth of the ratchet wheel 833, quickly releasing the locking of the ratchet wheel 833 by the ratchet 835, so that the rotation direction of the nut 7 on the outside of the bolt 5 is not restricted, so as to facilitate the separation of the nut 7 and the bolt 5. When the above-mentioned insertion rod 841 drives the top block 843 to squeeze the ratchet 835, the second spring 842 is in a pulling state. Then, when the insertion rod 841 is loosened, the elastic force of the second spring 842 pulls the top block 843, so that the insertion rod 841 drives the top block 843 to release the ratchet 833 and automatically pushes the insertion rod 841 back to its original position. The automatic resetting of the insertion rod 841 simplifies the operation process and reduces the possibility of operation errors. After tightening or loosening operations, the user does not need to manually reset the position of the insertion rod 841, thereby improving work efficiency.

[0058] Working principle: The user inserts the slider 610 into the inside of the slide groove 310, and the limit block 620 follows the slider 610 to be inserted into the inside of the limit groove 320, and the gas generator device 110 and the frame 120 are placed directly above the carrier plate 210, and the positions of the gas generator device 110 and the frame 120 are fine-tuned so that the holes opened inside the frame 120 correspond to the slide groove 310. The staff drives the slider 610 and the limit block 620 to slide inside the slide groove 310 and the limit groove 320 to directly below the holes opened inside the frame 120, and the positions of the gas generator device 110 and the frame 120 are fine-tuned again so that the holes opened inside the frame 120 correspond to the slider 610, and the bolt 5 is inserted into the limit The frame 4 passes through the hole and the slider 610 opened inside the frame 120, and the top of the bolt 5 is stuck in the inside of the limit frame 4. Then the limit plate 630 and the gasket 650 are sequentially put upward from the bottom of the bolt 5. When the nut 7 is placed inside the sleeve block 810, the rotating disk 823 drives the nut 7 to engage with the bottom of the bolt 5 through the threaded sleeve 822, the circular gear 821 and the sleeve block 810. At the same time, the threaded sleeve 822 is synchronously engaged with the bolt 5 through the thread. The gasket 650 and the limit plate 630 are squeezed by the nut 7, so that the limit plate 630 drives the helical teeth 640 to engage in the inside of the slot 330, and then the position of the slider 610 is in an engaged state, so that the frame 120 and the supporting plate 210 are stably installed together.

[0059] When the circular gear 821 follows the nut 7 to mesh and rotate with the bolt 5 through the sleeve block 810, the circular gear 821 meshes with the wide gear 825 through the teeth, and the ratchet 833 and the rotating shaft 824 are coaxially arranged with the rotating shaft 824 as the rotating shaft, so that the ratchet 833 rotates following the wide gear 825. At this moment, the inclined surface of the ratchet 833 conflicts with the inclined surface of one end of the ratchet 835, so that the ratchet 835 rotates about the axis of the hinge rod 834, and the ratchet 835 squeezes the first spring 836, so that the ratchet 833 rotates following the wide gear 825, so that the ratchet 833 can rotate freely in one direction, while the ratchet 835 prevents the ratchet 833 from rotating in the opposite direction, thereby preventing the nut 7 from rotating in the opposite direction on the outside of the bolt 5, thereby increasing the pre-tightening force of the nut 7 on the bolt 5.

[0060] By pressing the insert rod 841, the insert rod 841 drives the top block 843 to squeeze the outer side of the ratchet 835, so that the ratchet 835 rotates about the axis of the hinge rod 834, and the ratchet 835 squeezes the first spring 836. At this moment, the other end of the ratchet 835 disengages from the teeth of the ratchet wheel 833, so that the rotation direction of the ratchet wheel 833 is not restricted. The rotating disk 823 drives the nut 7 to engage with the outer side of the bolt 5 through the threaded sleeve 822, the circular gear 821 and the sleeve block 810. When the nut 7 disengages from the outer side of the bolt 5, the bolt 5 is taken out from the inside of the slider 610 and the limit frame 4, so as to facilitate the separation of the frame 120 and the supporting plate 210.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
