Description

Technical Field

[0001] This utility model relates to the field of engine chassis mounting bracket technology, and more specifically, it relates to an engine chassis mounting bracket. Background Technology

[0002] In existing technologies, engine mounting brackets, as crucial support components in engine installation systems, are widely used in automotive manufacturing, construction machinery, marine power, power generation equipment, and industrial machinery. They provide reliable fixation and stable support to prevent displacement or tilting during operation. However, in practical applications, fixing or removing the engine from the bracket typically requires specialized equipment such as wrenches and screwdrivers. This process is cumbersome and demands a high level of skill from operators. Furthermore, when the engine needs installation, commissioning, regular maintenance, troubleshooting, replacement, or relocation, incompatible tools, incomplete equipment, or limited operating environments often prevent timely installation and removal. This not only impacts installation efficiency and maintenance progress but can also lead to bracket deformation and damage, and prolonged equipment downtime due to improper handling.

[0003] Secondly, although some improved equipment has achieved convenient fixing and removal of the engine through the cooperation of some snap-fit ​​structures and quick-release parts, its fixing structure design is simple and lacks stability and reliability. It is easy for the fixing structure to loosen or even fall off due to external forces such as vibration and impact generated during engine operation, dynamic load fluctuations caused by load changes, and external collisions. This not only affects the installation stability and operational safety of the engine, but may also cause problems such as engine displacement and tilting, equipment damage and failure, personnel safety hazards, increased risk of production accidents, and expanded economic losses.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a fixed chassis bracket for an engine, which has the following advantages: 1. A tool-free quick-release system, consisting of a control sleeve, clamping sleeve, clamping rod, travel groove, travel plate, clamping bracket, and return spring, is constructed within the engine mounting chassis bracket. When engine removal is required, the user rotates the control sleeve forward, causing the travel groove to rotate. The return spring then pushes the travel plate outward, causing the clamping bracket to be pulled out of the clamping groove, thus removing the clamping sleeve and clamping rod. To install and secure the engine, the reverse operation is performed. This effectively solves the problem of insufficient power when fixing the engine to a bracket or removing the engine from a mounting chassis. Removing the engine from the bracket usually requires the use of specialized equipment such as wrenches and screwdrivers for auxiliary fixing and disassembly. The operation steps are cumbersome and complex, and require a high level of skill from the operators. In cases where the professional tools are not compatible, the tools are not complete, or the operating environment is limited, timely disassembly and assembly operations are usually not possible. This not only affects the installation efficiency and maintenance progress of the engine, but may also cause bracket deformation and damage due to improper disassembly and assembly operations, and prolong equipment downtime. The tool-free disassembly and assembly operation of the engine has been realized, which improves the installation and maintenance efficiency and ease of operation of the engine.

[0014] 2. A multi-layered stabilizing and locking system is constructed using components such as a rotation rod, mounting bracket, sliding sleeve, support rod, movable plate, actuating plate, actuating hole, actuating groove, transmission block, transmission spring, support spring, and guide block. After the engine is installed and fixed, the support rod, together with the movable plate at its top, supports the sliding sleeve to one side of the actuating plate. The guide block and guide groove further limit the sliding sleeve, preventing accidental slippage. The outer wall of the sliding sleeve limits the rotation rod, preventing it from moving. The rotation rod and the actuating groove work together to limit the rotation of the control sleeve, preventing accidental rotation and thus preventing accidental unlocking of the fixed structure. This effectively solves the problem of existing... The technical defects of some improved equipment in the technology are that the fixed structure design is simple, lacks stability and reliability, and is prone to loosening or even accidental detachment due to external forces such as vibration and impact generated during engine operation, dynamic load fluctuations caused by load changes, and external collisions. This not only affects the installation stability and operational safety of the engine, but may also cause engine displacement and tilting, equipment damage and failure, personnel safety hazards, increased risk of production accidents, and expanded economic losses. The technology ensures the stability and reliability of the fixed structure and guarantees the safe and stable operation of the engine fixed chassis support. Attached Figure Description

[0020] Please see Figures 1-5 A mounting bracket for an engine chassis includes a base 1, a fixed seat 2 fixedly mounted on the base 1, a movable seat 3 movably mounted on the base 1, a detachable clamping sleeve 4 on both the movable seat 3 and the fixed seat 2, a detachable clamping rod 5 on the inner side of the clamping sleeve 4, a mounting bracket 6 fixedly mounted on the outer side of the clamping sleeve 4, a rotating rod 7 rotatably mounted in the mounting bracket 6, a control sleeve 8 rotatably mounted on the outer side of the clamping sleeve 4, a plurality of moving grooves 9 on one side of the control sleeve 8, an actuating plate 10 rotatably mounted on the outer side of the clamping sleeve 4, an actuating hole 11 and an actuating groove 12 on the actuating plate 10, the actuating groove 12 being arc-shaped and the actuating hole 11 being located at one end of the actuating groove 12, and the actuating plate 10 being... A transmission block 13 is fixedly connected to the side, and a transmission spring 14 is connected to one side of the transmission block 13. A matching block 15 is fixedly fixed to the outside of the clamping sleeve 4, and the other end of the transmission spring 14 is connected to the matching block 15. A clamping frame 16 is slidably provided on the side wall of the clamping sleeve 4. A clamping groove 17 is opened on the outside of the clamping rod 5. One end of the clamping frame 16 is inserted into the clamping groove 17. A traveling plate 18 is fixedly connected to one side of the clamping frame 16. A traveling groove 19 is opened in a variable diameter manner on the inside of the control sleeve 8. The outer wall of the traveling plate 18 fits against the inner wall of the traveling groove 19. A sliding sleeve 20 is slidably sleeved on the outside of the clamping sleeve 4. A support rod 21 is fixedly provided on one side of the sliding sleeve 20. A movable plate 22 is fixedly provided on the support rod 21. There are two movable plates 22.

[0021] A motor 23 is detachably mounted on one side of the base 1, and a lead screw 24 is rotatably mounted on the inner side of the base 1. The movable seat 3 is movably connected to the lead screw 24 via a thread. The output end of the motor 23 is connected to one end of the lead screw 24. Sliding grooves 25 are provided on both sides of the base 1, and sliding blocks 26 are slidably mounted in the sliding grooves 25. The sliding blocks 26 are detachably mounted on both sides of the movable seat 3. Multiple insertion holes 27 are provided on both the fixed seat 2 and the movable seat 3, and the insertion holes 27 on both sides of the movable seat 3 and the fixed seat 2 are symmetrically arranged.

[0022] In this embodiment, when the engine needs to be removed, the actuating plate 10 is first rotated forward. The actuating plate 10 drives the transmission block 13 on one side to rotate forward, and the transmission block 13 drives the transmission rod 30 on one side to rotate forward along the matching hole 29. At the same time, the transmission block 13 and the matching block 15 cooperate to compress the transmission spring 14. Simultaneously, the actuating plate 10 drives the actuating hole 11 and the actuating groove 12 to rotate forward. When the transmission spring 14 is compressed to its limit, the actuating hole 11 rotates to a position concentric with the movable plate 22. Then, the sliding sleeve 20 is pushed, causing the sliding sleeve 20 to drive the inner guide block 33 to slide along the guide groove 32, and causing the sliding... The sliding sleeve 20 drives one side of the support rod 21 and the movable plate 22 to slide into the action hole 11. The sliding sleeve 20 and the action plate 10 cooperate to compress the support spring 34 sleeved on the outside of the support rod 21. When the support spring 34 is compressed to its limit, the movable plate 22 set in the middle of the support rod 21 just slides through the action hole 11 and moves to the other side of the action plate 10. At this time, the action plate 10 is released, and the transmission spring 14 will reset and push the transmission block 13, so that the transmission block 13 drives one side of the transmission rod 30 to rotate in the opposite direction along the matching hole 29. The transmission block 13 will also drive the action hole 11 and the action groove 12 to rotate in the opposite direction through the action plate 10, so that the support rod 21 enters When the outer wall of the support rod 21 contacts one end of the inner wall of the motion groove 12, the motion plate 10 stops rotating. At this time, the support rod 21, together with the middle section movable plate 22, limits the sliding sleeve 20 to one side of the motion plate 10, so that the outer wall of one end of the sliding sleeve 20 no longer limits one end of the indexing rod 7. Then, the control sleeve 8 is rotated in the forward direction, and the control sleeve 8 will drive one side of the motion groove 9 to rotate in the forward direction. Then, the inner wall of the motion groove 9 presses against one end of the indexing rod 7. Due to the arc structure design of the two ends of the indexing rod 7 and the inner wall of the motion groove 9, the indexing rod 7 will then rotate in the mounting frame 6, so that one end of the indexing rod 7 moves out of the motion groove 9, and the other end of the indexing rod 7 will move closer to the card. When the tight sleeve 4 rotates in the direction of rotation, the control sleeve 8 will drive the inner variable-diameter travel groove 19 to rotate synchronously in the forward direction. Then, the return spring 28 gradually returns to its original position and pushes the travel plate 18, causing the travel plate 18 to move outward, so that the outer wall of the travel plate 18 is always in contact with the inner wall of the travel groove 19. At the same time, the travel plate 18 will drive the clamping bracket 16 to slide outward, so that the clamping bracket 16 is gradually pulled out of the clamping groove 17. Then, the clamping sleeve 4 and the clamping rod 5 are pulled up and down to the upper and lower sides respectively, so that the clamping sleeve 4 and the clamping rod 5 can be removed here. Then, refer to the above steps to remove the other corresponding clamping sleeves 4 and clamping rods 5, and then the engine can be removed.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: one end of the sliding sleeve 20 adopts a beveled structure design, and both ends of the indexing rod 7 and the inner edge of the moving groove 9 adopt a rounded structure design. A return spring 28 is movably provided on the outer side of the clamping frame 16. The two ends of the return spring 28 are respectively connected to one side of the traveling plate 18 and the outer wall of the clamping sleeve 4.

[0024] Matching block 15 has a matching hole 29. A transmission rod 30 is connected to one side of transmission block 13. One end of transmission rod 30 slides into the matching hole 29. Transmission spring 14 is movably sleeved on the outside of transmission rod 30.

[0025] Multiple anti-slip strips 31 are fixedly provided on the outer walls of the control sleeve 8, the sliding sleeve 20, and the action plate 10.

[0026] A guide groove 32 is provided on the outer side of the clamping sleeve 4, and a guide block 33 is provided in the guide groove 32. The guide block 33 is fixedly installed on the inner side of the sliding sleeve 20.

[0027] A spring 34 is movably sleeved on the outside of the support rod 21. One end of the spring 34 is connected to the sliding sleeve 20, and the other end of the spring 34 is in contact with the action plate 10.

[0028] More specifically, when the engine needs to be installed and fixed, firstly, the motor 23 is turned on, causing the lead screw 24 to rotate. Due to the threaded connection between the lead screw 24 and the movable seat 3, the movable seat 3 will then drive the sliding block 26 to slide along the sliding groove 25, adjusting the positions of the fixed seat 2 and the movable seat 3 to achieve longitudinal adaptation of the engine. Then, the engine is placed on the fixed seat 2 and the movable seat 3, so that the reserved mounting holes on the engine are concentrically aligned with the corresponding insertion holes 27 on the fixed seat 2 and the movable seat 3. Then, multiple clamping rods 5 are passed through the insertion holes 27 on the fixed seat 2 or the movable seat 3 from the bottom, while also passing through the reserved mounting holes on the engine. Then, the clamping sleeve 4 is fitted onto the outside of the clamping rods 5 from the top. After the control sleeve 8 is rotated in the reverse direction, it will drive the moving groove 9 on one side to rotate in the reverse direction and reset. The control sleeve 8 will also drive the inner variable-diameter travel groove 19 to rotate in the reverse direction and reset. Then, the inner wall of the travel groove 19 gradually presses against the outer wall of the travel plate 18, causing the travel plate 18 to slide inward. The travel plate 18 will cooperate with the outer wall of the clamping sleeve 4 to press against the reset spring 28. At the same time, the travel plate 18 will drive the clamping bracket 16 on one side to gradually slide inward and reset, causing one end of the clamping bracket 16 to re-clamp into the clamping groove 17. At this time, the control sleeve 8 drives the original moving groove 9 to rotate to the position corresponding to the indexing rod 7. Then, the action plate 10 is rotated in the forward direction again, causing the action plate 10 to drive the action hole 11 and the action groove 12 to rotate in the forward direction again. The action plate 10 will then drive another... The side transmission block 13 rotates forward, and then the transmission block 13 and the matching block 15 cooperate again to press the transmission spring 14. When the actuating hole 11 rotates to the position concentric with the movable plate 22, the support spring 34 resets and pushes the sliding sleeve 20 to slide reset. Then the sliding sleeve 20 will drive the inner guide block 33 to slide reset along the guide groove 32, and the sliding sleeve 20 will drive the one-side support rod 21 and the two movable plates 22 to slide reset. At the same time, the oblique structure at one end of the sliding sleeve 20 will push the arc structure at the corresponding end of the indexing rod 7 outward, so that the indexing rod 7 will rotate and reset in the reverse direction in the mounting frame 6. When the support spring 34 is fully reset, the movable plate 22 set at the top of the support rod 21 moves back to the original side of the actuating plate 10, and the other end of the indexing rod 7 is inserted into the... In the action groove 9, the action plate 10 is released again. The transmission spring 14 pushes the transmission block 13 to rotate in the opposite direction and reset. Then, the transmission block 13 drives the transmission rod 30 on one side to rotate in the opposite direction and reset. The transmission block 13, through the action plate 10, drives the action hole 11 and the action groove 12 to rotate in the opposite direction and reset to a position that does not correspond to the support rod 21 and the movable plate 22. Then, the support rod 21, together with the movable plate 22 at its top, supports the sliding sleeve 20 to one side of the action plate 10. With the help of the guide block 33 and the guide groove 32, the sliding sleeve 20 is limited to prevent accidental sliding. The outer wall of the sliding sleeve 20 limits the rotation rod 7, making the rotation rod 7 unable to move. Then, the rotation rod 7 and the action groove 9 work together to limit the rotation of the control sleeve 8 and prevent the control sleeve 8 from rotating accidentally.This prevents accidental unlocking of the fixing structure, thus ensuring stable installation of the engine.

[0029] In summary, during the use or operation of the overall equipment: when the engine needs to be removed, first rotate the actuating plate 10 forward. The actuating plate 10 drives the transmission block 13 on one side to rotate forward, and the transmission block 13 drives the transmission rod 30 on one side to rotate forward along the matching hole 29. At the same time, the transmission block 13 and the matching block 15 cooperate to compress the transmission spring 14. Simultaneously, the actuating plate 10 drives the actuating hole 11 and the actuating groove 12 to rotate forward. When the transmission spring 14 is compressed to its limit, the actuating hole 11 rotates to a position concentric with the movable plate 22, and then pushes the sliding sleeve 20, causing the sliding sleeve 20 to drive the inner guide block 33 along the guide groove 32. The sliding sleeve 20 causes one side of the support rod 21 and the movable plate 22 to slide into the action hole 11. The sliding sleeve 20 and the action plate 10 cooperate to compress the support spring 34 sleeved on the outside of the support rod 21. When the support spring 34 is compressed to its limit, the movable plate 22 set in the middle of the support rod 21 just slides through the action hole 11 and moves to the other side of the action plate 10. At this time, the action plate 10 is released, and the transmission spring 14 will reset and push the transmission block 13, so that the transmission block 13 drives one side of the transmission rod 30 to rotate in the opposite direction along the matching hole 29. The transmission block 13 will also drive the action hole 11 and the action groove 12 to rotate in the opposite direction through the action plate 10, so that the support rod 21 enters the action groove 12. When the outer wall of the support rod 21 contacts one end of the inner wall of the action groove 12, the action plate 10 stops rotating. At this time, the support rod 21, together with the middle section movable plate 22, limits the sliding sleeve 20 to one side of the action plate 10, so that the outer wall of one end of the sliding sleeve 20 no longer limits one end of the indexing rod 7. Then, the control sleeve 8 is rotated in the forward direction. The control sleeve 8 will drive one side of the action groove 9 to rotate in the forward direction. Then, the inner wall of the action groove 9 presses against one end of the indexing rod 7. Due to the arc structure design of the two ends of the indexing rod 7 and the inner wall of the action groove 9, the indexing rod 7 will then rotate in the mounting frame 6, so that one end of the indexing rod 7 moves out of the action groove 9, and the other end of the indexing rod 7 will move towards the... When the clamping sleeve 4 is rotated in the direction of the control sleeve 8, the inner variable-diameter travel groove 19 will rotate synchronously in the forward direction. Then, the return spring 28 will gradually return to its original position and push the travel plate 18, causing the travel plate 18 to move outward, so that the outer wall of the travel plate 18 is always in contact with the inner wall of the travel groove 19. At the same time, the travel plate 18 will drive the clamping bracket 16 to slide outward, so that the clamping bracket 16 will gradually be pulled out of the clamping groove 17. Then, the clamping sleeve 4 and the clamping rod 5 will be pulled up and down to remove the clamping sleeve 4 and the clamping rod 5 at this point. Then, the other corresponding clamping sleeves 4 and clamping rods 5 will be removed by referring to the above steps. Then the engine can be removed.

[0030] When the engine needs to be installed and fixed, first turn on the motor 23, which drives the lead screw 24 to rotate. Due to the threaded connection between the lead screw 24 and the movable seat 3, the movable seat 3 will drive the sliding block 26 to slide along the sliding groove 25, adjusting the position of the fixed seat 2 and the movable seat 3 to achieve longitudinal adaptation of the engine. Then, place the engine on the fixed seat 2 and the movable seat 3, so that the reserved mounting holes on the engine are concentrically aligned with the corresponding insertion holes 27 on the fixed seat 2 and the movable seat 3. Then, pass multiple clamping rods 5 through the insertion holes 27 on the fixed seat 2 or the movable seat 3 from the bottom, while also passing the clamping rods 5 through the reserved mounting holes on the engine. Then, fit the clamping sleeve 4 onto the outside of the clamping rods 5 from the top, and then rotate in the opposite direction to operate. The control sleeve 8 will drive the one-sided moving groove 9 to rotate in the opposite direction to reset, and the control sleeve 8 will also drive the inner variable-diameter traveling groove 19 to rotate in the opposite direction to reset. Then, the inner wall of the traveling groove 19 will gradually press against the outer wall of the traveling plate 18, causing the traveling plate 18 to slide inward. The traveling plate 18 will cooperate with the outer wall of the clamping sleeve 4 to press against the reset spring 28. At the same time, the traveling plate 18 will drive the one-sided clamping bracket 16 to gradually slide inward to reset, so that one end of the clamping bracket 16 will re-clamp into the clamping groove 17. At this time, the control sleeve 8 will drive the original moving groove 9 to rotate to the position corresponding to the indexing rod 7, and then rotate the action plate 10 in the forward direction again, so that the action plate 10 will drive the action hole 11 and the action groove 12 to rotate in the forward direction again. The action plate 10 will also drive the one-sided transmission block 13 to rotate in the forward direction again. The transmission block 13 and the matching block 15 work together again to press the transmission spring 14. When the actuating hole 11 rotates to the position concentric with the movable plate 22, the support spring 34 resets and pushes the sliding sleeve 20 to slide reset. Then the sliding sleeve 20 will drive the inner guide block 33 to slide reset along the guide groove 32, and the sliding sleeve 20 will drive the support rod 21 on one side and the two movable plates 22 to slide reset. At the same time, the oblique structure at one end of the sliding sleeve 20 will push the arc structure at the corresponding end of the indexing rod 7 outward, so that the indexing rod 7 will rotate and reset in the opposite direction in the mounting frame 6. When the support spring 34 is fully reset, the movable plate 22 at the top of the support rod 21 moves back to the original side of the actuating plate 10, and the other end of the indexing rod 7 is inserted into the moving groove 9. Then it is released again. When the actuation plate 10 is activated, the transmission spring 14 pushes the transmission block 13 to rotate in the opposite direction and reset. Then, the transmission block 13 drives the transmission rod 30 on one side to rotate in the opposite direction and reset. The transmission block 13 also drives the actuation hole 11 and the actuation groove 12 to rotate in reverse and reset to a position that does not correspond to the support rod 21 and the movable plate 22 through the actuation plate 10. Then, the support rod 21, together with the movable plate 22 at its top, supports the sliding sleeve 20 to one side of the actuation plate 10. With the help of the guide block 33 and the guide groove 32, the sliding sleeve 20 is limited to prevent accidental sliding. The outer wall of the sliding sleeve 20 limits the rotation rod 7, making the rotation rod 7 unable to move. Then, the rotation rod 7 and the movement groove 9 work together to limit the rotation of the control sleeve 8, preventing the control sleeve 8 from rotating accidentally, thereby preventing the fixed structure from being accidentally unlocked.This ensures the stable installation of the engine.
