Description
Technical Field
[0001] This invention relates to the field of boiler maintenance auxiliary equipment technology, and in particular to a boiler support device for boiler maintenance and its usage method. Background Technology
[0002] As a core piece of equipment in industrial production and heating systems, boilers require periodic shutdowns for maintenance after long-term operation to ensure their safe and stable operation. During boiler maintenance, the boiler body or disassembled boiler components must be fixed and supported using support devices to detach them from the mounting base and maintain a stable posture, so that maintenance personnel can perform internal inspections, component replacements, and other operations. For example, a support device for the maintenance of a thermal production boiler, with application number "202310198467.0", includes a mounting block and a support plate. A height adjustment mechanism is fixedly installed on the top surface of the mounting block, and a telescopic mechanism is fixedly installed on the side of the mounting block. A clamping mechanism is fixedly installed on the top surface of the support plate. The height adjustment mechanism allows for adjustment of the height of the clamping mechanism; a motor provides power to the mechanism; a guide rail allows the mechanism to support the work area; the clamping mechanism allows for clamping the boiler for subsequent operations; a second motor provides power to the mechanism; the telescopic mechanism allows for adjustment of the horizontal distance of the device, further expanding its applicability; and a third motor provides power support. This invention is characterized by its strong practicality, wide applicability, and ease of movement.
[0003] Based on the aforementioned existing technology, it is known that existing boiler maintenance support devices, when in use, lack an effective synchronous linkage protective buffer structure. If the boiler is in a high position and there is no effective buffer structure, it may cause irreversible damage to maintenance personnel at the bottom if the boiler falls from a height, posing a safety hazard. Summary of the Invention

The driving bevel gear is fixedly installed at the bottom end of the outer wall of the transmission screw. The connecting frame is fixedly installed at the front end of the driving guide rail and the driven guide rail. The driven bevel gear is rotatably installed inside the connecting frame and meshes with the driving bevel gear for transmission. The support member is fixedly installed on the outer wall of the support base. The air cylinder is fixedly installed at the top end of the support member. The piston rod is movably installed inside the air cylinder. The piston plate is fixedly installed at one end of the piston rod.
[0006] Preferably, a linkage mechanism is fixedly provided at the outer end of the driven bevel gear. The linkage mechanism includes a turntable, a first connecting rod, and a second connecting rod. The turntable is fixedly provided on the outer side of the driven bevel gear. The first connecting rod is eccentrically provided on the outer wall of the turntable. The second connecting rod is hinged to the first connecting rod.
[0007] Preferably, the end of the second connecting rod away from the first connecting rod is hinged to the piston rod. When the turntable is rotating, the first connecting rod and the second connecting rod are in a state of synchronously pushing the piston rod and the piston plate to slide along the inner wall of the air cylinder.
[0008] Preferably, a guide mechanism is fixedly connected to the top surface of the support base. The guide mechanism includes a buffer guide rail, a buffer arm, a buffer bracket, and a buffer plate. The buffer guide rail is fixedly disposed at the top of the support base, the buffer arm is slidably disposed within the buffer guide rail, and the buffer bracket is fixedly disposed at the top of the buffer arm.
[0009] Preferably, one end of the buffer support plate is fixedly disposed on the outer wall of the buffer bracket, the other end of the buffer support plate is fixedly connected to the top end of the buffer support arm, and a buffer mechanism is provided inside the buffer guide rail.
[0010] Preferably, the buffer mechanism includes a buffer cylinder, a buffer support rod, a pressure relief pipe, a pressure relief valve, an air supply pipe, and a one-way valve. The buffer cylinder is fixedly installed inside the buffer guide rail and located below the buffer support arm. The buffer support rod is movably installed inside the buffer cylinder, and the top end of the buffer support rod is fixedly connected to the bottom end of the buffer support arm.
[0011] Preferably, the pressure relief pipe is fixedly installed on the outer wall of the buffer cylinder, the pressure relief pipe communicates with the buffer cylinder, and a pressure relief valve is provided on the outer wall of the pressure relief pipe. One end of the air supply pipe is connected to the buffer cylinder, and the other end of the air supply pipe is connected to the air cylinder.
[0012] Preferably, the active mechanism includes a pulley and a transmission belt, the pulley is fixedly disposed on the outer wall of the transmission screw, and the transmission belt is connected to the pulley by friction transmission.
[0013] Preferably, the active guide rail is internally equipped with a support mechanism, which includes a displacement arm, a guide slider, a bracket, a support plate, and a boiler component. The displacement arm is slidably disposed within the active guide rail, and the displacement arm has a screw hole inside that matches the transmission screw. The guide slider is fixedly disposed on the outer wall of the displacement arm, the bracket is fixedly disposed on the top end of the displacement arm, the support plate is fixedly disposed on the top end of the displacement arm, and the boiler component is placed on the top end of the bracket.
[0014] This invention discloses a method for using a boiler support device for boiler maintenance, comprising the following steps: S1. Place the support base in the designated working position, and fix the active guide rail, driven guide rail, connecting bracket and bracket components on the top of the support base; fix the servo motor on the connecting bracket and fix the air cylinder on the top of the bracket components to complete the installation and positioning of the basic components of the device; S2. Start the servo motor. The output shaft at the bottom of the servo motor drives the transmission screw to rotate. The transmission screw rotates along its own axis inside the active guide rail and the driven guide rail. At the same time, the drive bevel gear at the bottom of the outer wall of the transmission screw rotates synchronously with the transmission screw. S3. The drive bevel gear meshes with the driven bevel gear inside the connecting frame, transmitting rotational power to the driven bevel gear, so that the driven bevel gear rotates stably around its own axis inside the connecting frame. S4. When the driven bevel gear rotates, the turntable fixedly connected to its outer side rotates synchronously; the first connecting rod eccentrically set on the outer wall of the turntable moves with the turntable, thereby driving the second connecting rod hinged to the first connecting rod to move synchronously. S5. The end of the second connecting rod away from the first connecting rod pushes the piston rod, and the piston rod drives the piston plate fixed at one end to slide along the inner wall of the air cylinder to compress the gas inside the air cylinder. S6. Connect the air cylinder to the buffer cylinder inside the buffer guide rail through the air supply pipe. The compressed gas in the air cylinder enters the buffer cylinder through the air supply pipe. The one-way valve on the air supply pipe controls the gas to flow unidirectionally to the buffer cylinder. S7. During the rotation of the transmission screw, it engages with the matching screw hole inside the displacement arm to drive the displacement arm to slide along the active guide rail; the bracket and support plate fixed at the top of the displacement arm are adjusted to the designated position along with the displacement arm, and the boiler component is placed on the top of the bracket for support. S8. When the boiler components show a tendency to fall, the buffer support arm slides into the buffer guide rail, causing the buffer support rod fixed at its bottom to move into the buffer cylinder; the compressed gas in the buffer cylinder generates a reverse buffering force, and the amount of gas released in the buffer cylinder can be controlled by adjusting the pressure relief valve on the pressure relief pipe to adjust the buffering force.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, a support base provides a stable bearing foundation for the entire device, ensuring the installation stability of the active mechanism and the transmission mechanism. In the active mechanism, the active guide rail and the driven guide rail jointly limit the transmission screw, so that the servo motor drives the transmission screw to rotate with precision. The transmission screw drives the drive bevel gear on the outer wall to rotate synchronously. By meshing with the driven bevel gear rotating on the connecting frame, the power is transmitted to the piston rod, pushing the piston plate to move in the air cylinder fixed by the support component. A stable air pressure buffer environment is built in advance. When the boiler shows a tendency to fall, the compressed gas in the air cylinder can immediately generate a buffer force to offset the impact, preventing the boiler from directly hitting the bottom, completely eliminating the safety hazards of the existing device, and ensuring the safety of maintenance personnel.
[0016] 2. In this invention, the integrated design of buffering power and supporting power is achieved through a mechanical structure, eliminating the need for an additional power source. The servo motor of the active mechanism drives the transmission screw to complete the boiler support adjustment, and at the same time, through the meshing transmission of the driven bevel gear and the driven bevel gear, it directly provides motion power to the piston rod and piston plate of the transmission mechanism. The support base fixes the active guide rail, the driven guide rail and the bracket components, ensuring the positional accuracy of each transmission component and avoiding offset or jamming during power transmission. The tight cooperation between the air cylinder and the piston plate ensures the stability of the air pressure buffer. This simplifies the overall structure of the device, reduces the failure points of additional components, and lowers the manufacturing cost and maintenance difficulty of the equipment, solving the problems of redundant structure and high operating cost of existing devices.
[0017] 3. In this invention, through mechanical linkage design, the synchronous response of the buffering function and the support adjustment function is realized. When the servo motor starts and drives the transmission screw to rotate, the driving bevel gear on the outer wall of the transmission screw immediately drives the driven bevel gear to rotate, thereby pushing the piston rod and piston plate to move in the air cylinder. The buffering preparation action and the support adjustment action are carried out simultaneously, without the need for additional waiting for the buffering structure. The radial limit of the transmission screw by the active guide rail and the driven guide rail ensures the meshing accuracy of the driving bevel gear and the driven bevel gear, avoiding transmission delay that leads to buffering lag. The stable support of the support base further ensures the reliability of the linkage of each component, so that the device always maintains the instantaneous buffering capability during the boiler position adjustment process, solving the problem of slow buffering response and inability to deal with sudden drop risks in the existing device.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0021] Example, refer to Figures 1-8A boiler support device for boiler maintenance and its usage method are disclosed. The device includes a support base 1, with an active mechanism fixedly connected to the top surface of the support base 1. The active mechanism includes an active guide rail 101, a connecting bracket 1011, a servo motor 1012, a driven guide rail 1013, and a transmission screw 1014. The active guide rail 101 is fixedly mounted on the top surface of the support base 1, the connecting bracket 1011 is fixedly mounted on the top surface of the active guide rail 101, the servo motor 1012 is fixedly mounted on the connecting bracket 1011, and the driven guide rail 1013 is fixedly mounted on the top surface of the active guide rail 101. 13 is fixedly installed at the top of the support base 1. The transmission screw 1014 is fixedly installed at the bottom output shaft of the servo motor 1012. The transmission screw 1014 is rotatably installed within the active guide rail 101 and the driven guide rail 1013. A transmission mechanism is fixedly installed on the outer wall of the transmission screw 1014. The transmission mechanism includes a driving bevel gear 4, a connecting frame 401, a driven bevel gear 4011, a support member 4012, an air cylinder 4013, a piston rod 4014, and a piston plate 4015. The driving bevel gear 4 is fixedly installed on the transmission screw. At the bottom of the outer wall of 1014, a connecting frame 401 is fixedly mounted on the front end of the active guide rail 101 and the driven guide rail 1013. A driven bevel gear 4011 is rotatably mounted inside the connecting frame 401, and the driven bevel gear 4011 meshes with the driving bevel gear 4 for transmission. A support member 4012 is fixedly mounted on the outer wall of the support base 1. An air cylinder 4013 is fixedly mounted on the top end of the support member 4012. A piston rod 4014 is movably mounted inside the air cylinder 4013. A piston plate 4015 is fixedly mounted on one side of the piston rod 4014. At the end, the active mechanism (active guide rail 101, connecting bracket 1011, servo motor 1012, driven guide rail 1013, transmission screw 1014) at the top of the support base 1 drives the transmission mechanism (driving bevel gear 4, connecting frame 401, driven bevel gear 4011, bracket 4012, air cylinder 4013, piston rod 4014, piston plate 4015) to operate, realizing the movement of piston plate 4015 and piston rod 4014 within air cylinder 4013, providing a power basis for the subsequent buffering function of the device.
[0022] Furthermore, a linkage mechanism is fixedly provided at the outer end of the driven bevel gear 4011. The linkage mechanism includes a turntable 5, a first connecting rod 501, and a second connecting rod 5011. The turntable 5 is fixedly provided on the outer side of the driven bevel gear 4011. The first connecting rod 501 is eccentrically provided on the outer wall of the turntable 5. The second connecting rod 5011 is hinged to the first connecting rod 501. Through the linkage mechanism (turntable 5, first connecting rod 501, and second connecting rod 5011) at the outer end of the driven bevel gear 4011, the rotation of the driven bevel gear 4011 is converted into the linkage driving force of the first connecting rod 501 and the second connecting rod 5011, which transmits power to the movement of the piston rod 4014.
[0023] Furthermore, the end of the second connecting rod 5011 furthest from the first connecting rod 501 is hinged to the piston rod 4014. When the turntable 5 is rotating, the first connecting rod 501 and the second connecting rod 5011 are in a state of synchronously pushing the piston rod 4014 and the piston plate 4015 to slide along the inner wall of the air cylinder 4013. This ensures that when the turntable 5 rotates, the first connecting rod 501 and the second connecting rod 5011 synchronously push the piston rod 4014 and the piston plate 4015 to slide stably along the inner wall of the air cylinder 4013, thus ensuring that the inflation action of the air cylinder 4013 is carried out in an orderly manner.
[0024] Furthermore, a guide mechanism is fixedly connected to the top surface of the support base 1. The guide mechanism includes a buffer guide rail 3, a buffer support arm 301, a buffer bracket 3011, and a buffer support plate 3012. The buffer guide rail 3 is fixedly installed at the top of the support base 1. The buffer support arm 301 is slidably installed in the buffer guide rail 3. The buffer bracket 3011 is fixedly installed at the top of the buffer support arm 301. Through the guide mechanism (buffer guide rail 3, buffer support arm 301, buffer bracket 3011, and buffer support plate 3012) at the top of the support base 1, the buffer support arm 301 slides in the buffer guide rail 3, and works with the buffer bracket 3011 and the buffer support plate 3012 to provide guidance and initial support for the boiler.
[0025] Furthermore, one end of the buffer support plate 3012 is fixedly mounted on the outer wall of the buffer bracket 3011, and the other end of the buffer support plate 3012 is fixedly connected to the top end of the buffer support arm 301. The buffer guide rail 3 is provided with a buffer mechanism inside. The buffer bracket 3011 and the buffer support arm 301 are connected through the buffer support plate 3012 to enhance the structural stability of the guide mechanism. At the same time, the buffer mechanism inside the buffer guide rail 3 enhances the buffer protection capability of the device.
[0026] Furthermore, the buffer mechanism includes a buffer cylinder 6, a buffer support rod 601, a pressure relief pipe 6011, a pressure relief valve 6012, an air supply pipe 6013, and a one-way valve 6014. The buffer cylinder 6 is fixedly installed inside the buffer guide rail 3 and located below the buffer support arm 301. The buffer support rod 601 is movably installed inside the buffer cylinder 6, and the top end of the buffer support rod 601 is fixedly connected to the bottom end of the buffer support arm 301. Through the buffer mechanism (buffer cylinder 6, buffer support rod 601, pressure relief pipe 6011, pressure relief valve 6012, air supply pipe 6013, and one-way valve 6014), the buffer support arm 301 drives the buffer support rod 601 to move inside the buffer cylinder 6, thus constructing a buffer protection structure to cope with the impact of the boiler falling.
[0027] Furthermore, the pressure relief pipe 6011 is fixedly installed on the outer wall of the buffer cylinder 6, and the pressure relief pipe 6011 is in communication with the buffer cylinder 6. The outer wall of the pressure relief pipe 6011 is provided with a pressure relief valve 6012. One end of the air supply pipe 6013 is connected to the buffer cylinder 6, and the other end of the air supply pipe 6013 is connected to the air cylinder 4013. The pressure inside the buffer cylinder 6 is adjusted by the pressure relief pipe 6011 and the pressure relief valve 6012. The air supply pipe 6013 is used to connect the buffer cylinder 6 and the air cylinder 4013 to realize gas transmission, so as to ensure that the buffering effect of the buffer mechanism is controllable and stable.
[0028] Furthermore, the active mechanism includes a pulley 1015 and a transmission belt 1016. The pulley 1015 is fixedly mounted on the outer wall of the transmission screw 1014, and the transmission belt 1016 is connected to the pulley 1015 by friction transmission. Through the friction transmission between the pulley 1015 and the transmission belt 1016 in the active mechanism, the multiple transmission screws 1014 rotate synchronously, thereby improving the coordination and stability of the active mechanism's operation.
[0029] Furthermore, a support mechanism is installed inside the active guide rail 101. This support mechanism includes a displacement arm 2, a guide slider 201, a bracket 2011, a support plate 2012, and a boiler component 2013. The displacement arm 2 is slidably disposed within the active guide rail 101. The displacement arm 2 has a threaded hole inside that matches the transmission screw 1014. The guide slider 201 is fixedly disposed on the outer wall of the displacement arm 2. The bracket 2011 is fixedly disposed at the top end of the displacement arm 2. The support plate 2012 is fixedly installed at the top of the displacement arm 2, and the boiler component 2013 is placed at the top of the bracket component 2011. Through the support mechanism (displacement arm 2, guide slider 201, bracket component 2011, support plate 2012, boiler component 2013) in the active guide rail 101, the transmission screw 1014 drives the displacement arm 2 to slide stably. The boiler component 2013 is stably supported by the bracket component 2011 and the support plate 2012, which facilitates maintenance operations.
[0030] This invention discloses a method for using a boiler support device for boiler maintenance, comprising the following steps: S1. Place the support base 1 in the designated working position, and fix the active guide rail 101, driven guide rail 1013, connecting bracket 1011 and bracket 4012 on the top of the support base 1; fix the servo motor 1012 on the connecting bracket 1011, and fix the air cylinder 4013 on the top of the bracket 4012 to complete the installation and positioning of the basic components of the device; S2. Start the servo motor 1012. The output shaft at the bottom of the servo motor 1012 drives the transmission screw 1014 to rotate. The transmission screw 1014 rotates along its own axis inside the active guide rail 101 and the driven guide rail 1013. At the same time, the drive bevel gear 4 at the bottom of the outer wall of the transmission screw 1014 rotates synchronously with the transmission screw 1014. S3. The drive bevel gear 4 meshes with the driven bevel gear 4011, which is rotatably disposed inside the connecting frame 401, and transmits the rotational power to the driven bevel gear 4011, so that the driven bevel gear 4011 rotates stably around its own axis inside the connecting frame 401. S4. When the driven bevel gear 4011 rotates, the turntable 5 fixedly connected to its outer side rotates synchronously; the first connecting rod 501 eccentrically set on the outer wall of the turntable 5 moves with the turntable 5, thereby driving the second connecting rod 5011 hinged to the first connecting rod 501 to move synchronously. S5. The end of the second connecting rod 5011 away from the first connecting rod 501 pushes the piston rod 4014. The piston rod 4014 drives the piston plate 4015, which is fixed at one end, to slide along the inner wall of the air cylinder 4013, thereby compressing the gas inside the air cylinder 4013. S6. The air cylinder 4013 is connected to the buffer cylinder 6 inside the buffer guide rail 3 through the air supply pipe 6013. The compressed gas in the air cylinder 4013 enters the buffer cylinder 6 through the air supply pipe 6013. The one-way valve 6014 on the air supply pipe 6013 controls the gas to flow unidirectionally to the buffer cylinder 6. S7. During the rotation of the transmission screw 1014, it cooperates with the matching screw hole opened inside the displacement arm 2 to drive the displacement arm 2 to slide along the active guide rail 101; the bracket 2011 and support plate 2012 fixed at the top of the displacement arm 2 are adjusted to the designated position with the displacement arm 2, and the boiler component 2013 is placed on the top of the bracket 2011 for support. S8. When the boiler component 2013 shows a tendency to fall, the buffer support arm 301 slides into the buffer guide rail 3, causing the buffer support rod 601 fixed at its bottom end to move into the buffer cylinder 6; the compressed gas in the buffer cylinder 6 generates a reverse buffering force, and the amount of gas released in the buffer cylinder 6 can be controlled by adjusting the pressure relief valve 6012 on the pressure relief pipe 6011 to adjust the buffering force.
[0031] In use, the support base 1 serves as the core load-bearing component of the entire device. Its top surface is fixedly connected to the active guide rail 101 and the driven guide rail 1013 of the active mechanism, and the air cylinder 4013 of the transmission mechanism is fixed through the bracket 4012. The support base 1 provides a stable installation benchmark for the active mechanism and the transmission mechanism through its own stable structural characteristics, avoiding positional displacement of each component due to unstable foundation during subsequent mechanical actions, and ensuring the overall stability of the device from the root. The connecting bracket 1011 of the active mechanism is fixedly mounted on the top of the active guide rail 101. The servo motor 1012 is fixedly mounted on the connecting bracket 1011. The connecting bracket 1011 provides a rigid mounting carrier for the servo motor 1012, preventing the servo motor 1012 from becoming loose due to vibration during operation. When the device needs to start working, the servo motor 1012 is powered on and runs, and its bottom output shaft drives the transmission screw 1014 to rotate synchronously. Since the transmission screw 1014 is rotatably mounted inside the active guide rail 101 and the driven guide rail 1013, the active guide rail 101 and the driven guide rail 1013 form a bidirectional radial limit on the transmission screw 1014, restricting the transmission screw 1014 to rotate only along its own axis, avoiding radial sway or deviation during rotation, ensuring that the transmission screw 1014 maintains a precise rotation trajectory, and providing a stable foundation for subsequent power transmission. When the transmission screw 1014 rotates, the drive bevel gear 4, which is fixedly installed at the bottom of its outer wall, rotates synchronously with the transmission screw 1014. At this time, the connecting frame 401 is fixedly installed at the front end of the active guide rail 101 and the driven guide rail 1013. The driven bevel gear 4011, which is rotatably installed inside the connecting frame 401, forms a meshing transmission relationship with the drive bevel gear 4. The circumferential rotational power of the drive bevel gear 4 is transmitted to the driven bevel gear 4011 through the meshing action of the tooth surfaces, so that the driven bevel gear 4011 rotates stably around its own axis inside the connecting frame 401. The connecting frame 401 ensures that the driven bevel gear 4011 and the drive bevel gear 4 always maintain a precise meshing gap by supporting the rotation of the driven bevel gear 4011, so as to avoid tooth slippage, jamming or transmission delay during the power transmission process. The rotational power of the driven bevel gear 4011 directly acts on the piston rod 4014 of the transmission mechanism. The piston rod 4014 is movably inserted inside the air cylinder 4013, and one end of the piston rod 4014 extending into the air cylinder 4013 is fixedly connected to the piston plate 4015. The outer wall of the piston plate 4015 is tightly fitted with the inner wall of the air cylinder 4013 (ensuring gas sealing). Driven by the power of the driven bevel gear 4011, the piston rod 4014 drives the piston plate 4015 along the air cylinder 4013. The inner wall of 013 reciprocates axially. When the piston plate 4015 slides into the air cylinder 4013, the gas inside the air cylinder 4013 is compressed, gradually forming a pressure environment with a preset pressure. During this process, the support member 4012 provides a stable installation support for the air cylinder 4013 through a fixed connection with the support base 1, preventing the air cylinder 4013 from shifting position under the movement of the piston plate 4015 or the action of gas pressure, and ensuring the stable construction of the pressure buffer environment. During the rotation of the drive screw 1014 driven by the active mechanism, in addition to transmitting power to the transmission mechanism, the drive screw 1014 also uses its own rotational characteristics to cooperate with the device's support requirements for the boiler. Through cooperation with the relevant support structure, the boiler is kept in a stable state detached from the installation base during maintenance, which is convenient for maintenance personnel to operate. At the same time, the preset air pressure buffer environment built in the air cylinder 4013 is always in standby state: if the boiler has an unexpected tendency to fall during the support process, the compressed gas in the air cylinder 4013 will immediately transmit a reverse buffer force through the piston plate 4015 and piston rod 4014 to offset the impact kinetic energy when the boiler falls, and prevent the boiler from directly hitting the bottom of the device or the ground, so as to achieve synchronous coordination of support adjustment and buffer protection.

Place the support base (1) in the designated working position, and fix the active guide rail (101), driven guide rail (1013), connecting bracket (1011) and bracket (4012) on the top of the support base (1); fix the servo motor (1012) on the connecting bracket (1011), and fix the air cylinder (4013) on the top of the bracket (4012) to complete the installation and positioning of the basic components of the device; S2. Start the servo motor (1012). The output shaft at the bottom of the servo motor (1012) drives the transmission screw (1014) to rotate. The transmission screw (1014) rotates along its own axis inside the active guide rail (101) and the driven guide rail (1013). At the same time, the drive bevel gear (4) at the bottom of the outer wall of the transmission screw (1014) rotates synchronously with the transmission screw (1014). S3. The drive bevel gear (4) meshes with the driven bevel gear (4011) which is rotatably disposed inside the connecting frame (401), and transmits the rotational power to the driven bevel gear (4011), so that the driven bevel gear (4011) rotates stably around its own axis inside the connecting frame (401); S4. When the driven bevel gear (4011) rotates, the turntable (5) fixedly connected to its outer side rotates synchronously; the first connecting rod (501) eccentrically set on the outer wall of the turntable (5) moves with the turntable (5), thereby driving the second connecting rod (5011) hinged to the first connecting rod (501) to move synchronously. S5. The end of the second connecting rod (5011) away from the first connecting rod (501) pushes the piston rod (4014), and the piston rod (4014) drives the piston plate (4015) fixed at one end to slide along the inner wall of the air cylinder (4013) to compress the gas inside the air cylinder (4013). S6. The air cylinder (4013) is connected to the buffer cylinder (6) inside the buffer guide rail (3) through the air supply pipe (6013). The compressed gas in the air cylinder (4013) enters the buffer cylinder (6) through the air supply pipe (6013). The one-way valve (6014) on the air supply pipe (6013) controls the gas to flow unidirectionally to the buffer cylinder (6). S7. During the rotation of the transmission screw (1014), it engages with the matching screw hole inside the displacement arm (2) to drive the displacement arm (2) to slide along the active guide rail (101); the bracket (2011) and support plate (2012) fixed at the top of the displacement arm (2) are adjusted to the designated position along with the displacement arm (2) to place the boiler component (2013) on the top of the bracket (2011) for support; S8. When the boiler component (2013) shows a tendency to fall, the buffer support arm (301) slides into the buffer guide rail (3), causing the buffer support rod (601) fixed at its bottom end to move into the buffer cylinder (6); the compressed gas in the buffer cylinder (6) generates a reverse buffering force, and the amount of gas released in the buffer cylinder (6) can be controlled by adjusting the pressure relief valve (6012) on the pressure relief pipe (6011) to adjust the buffering force.
