Description

Technical Field

[0001] The present invention relates to the technical field of rotating bridges, and in particular to a rotating bridge device that is convenient for monitoring. Background Art

[0002] A rotating bridge is a bridge constructed using the rotation method. Bridge rotation construction refers to a construction method in which the bridge structure is formed in a position other than the design axis and then rotated into place. It can convert operations above obstacles into operations on shore or near the ground.

[0003] According to the rotation direction of the bridge structure, it can be divided into vertical rotation construction method, horizontal rotation construction method and a combination of horizontal and vertical rotation methods. Among them, the horizontal rotation method is the most widely used, mainly used in situations where support is not available, such as crossing canyons, rivers, railways, highways, etc. The rotation system of a rotating bridge consists of a lower turntable, an upper turntable, a ball joint, a slide, and a traction system. The rotation process is generally achieved by using a jack to pull the traction cable to form a rotational force to achieve rotation.

[0004] However, the existing transport fixing devices for rotating bridges usually require the rotating bridge to be fully wrapped before being fixed on the transport vehicle body. Therefore, when the rotating bridge arrives at the transportation location, its external packaging needs to be disassembled before its internal structure can be inspected, which is time-consuming and labor-intensive. Once a problem occurs with the internal rotating bridge body, the packaging structure needs to be reconnected to its exterior before transportation. Therefore, the existing transport packaging method is not convenient for inspecting and monitoring the rotating bridge.

[0005] At the same time, when the transport vehicle turns, the centrifugal force of the vehicle will drive the rotating bridge to generate centrifugal force synchronously, which will cause the rotating bridge to swing. If the device is rigidly connected to the rotating bridge, it will not only easily cause extrusion damage to the wall, but long-term use will also cause damage to the device.

[0006] At the same time, when the vehicle starts or brakes suddenly, the rotating bridge will tend to move in the opposite direction due to its own inertia. If it is not supported in time with limited protection, it will easily cause damage to the rotating bridge or tilt and collapse. And when the transport vehicle reaches an uneven road surface, the rotating bridge will shake synchronously with the bumps of the road, which will easily cause damage to its structure or performance. Summary of the Invention

[0007] The purpose of the present invention is to provide a rotating bridge device that is easy to monitor, which solves the problem that the existing transportation fixing devices for rotating bridges usually need to fully wrap the rotating bridge and then fix it on the transport vehicle body. Therefore, when the rotating bridge arrives at the transportation location, its external packaging needs to be disassembled before its internal structure can be inspected, which is time-consuming and labor-intensive. Once a problem occurs with the internal rotating bridge body, the packaging structure needs to be reconnected to its exterior before transportation. Therefore, the existing transportation packaging method is not convenient for inspecting and monitoring the rotating bridge. At the same time, its shock-absorbing and buffering performance is limited when the transport vehicle starts to brake suddenly, makes sharp turns or passes through bumpy roads, and the protection of the rotating bridge is not comprehensive.

[0008] To achieve the above-mentioned object, the present invention adopts the following technical solution: a rotating bridge device that is convenient for monitoring, comprising a rotating bridge, wherein the bottom of the rotating bridge is provided with a fixing portion through a central support portion, the bottoms of both ends of the rotating bridge are provided with end supports, the top of the rotating bridge is provided with a top limit portion, and a controller is provided on one side of the top limit portion;

[0009] The central support portion includes a central frame, a plurality of support plates are arranged in a linear and uniform array inside the central frame, a plurality of side plates are provided on both sides of the central frame, a plurality of large suction cups are provided inside the side plates through a first adjusting screw, a first channel is provided inside the first adjusting screw, the other end of the large suction cup is connected to the first channel, a small suction cup is provided inside the large suction cup through a plurality of support rods, the other end of the small suction cup is connected to a second channel, and the second channel is located inside the first channel;

[0010] The end support portion includes a bracket rotatably connected to the side wall of the central frame through a driving motor, a limiting horizontal plate is provided on the top of the bracket and is in contact with the side wall of the rotating bridge, a buffer airbag is provided on the side of the limiting horizontal plate close to the rotating bridge, and two groups of clamping airbags are symmetrically connected to the side of the buffer airbag close to the rotating bridge through a pressure valve, the clamping airbag and the buffer airbag have different contact surfaces with the rotating bridge respectively, an air pressure sensor is provided in the buffer airbag, and a pressure sensor is provided on the top of the limiting horizontal plate;

[0011] The top of each support plate is provided with a support member, and both sides of the top of each support member are provided with a support circular plate, and the support circular plate matches the position of the first adjusting screw. A support airbag is provided on the top of each support circular plate, and the support airbag is connected to the first channel and the second channel that are adjacent to each other. Multiple groups of the support airbags are connected to each other through exhaust pipes, and the other ends of the exhaust pipes located near both sides of the bracket are connected to the clamping airbags;

[0012] When the transport vehicle reaches a bumpy road section, the central frame moves upward, the small suction cup is squeezed into contact with the side wall of the rotating bridge and the internal gas flows along the second channel to the support airbag. After the top of the support airbag is squeezed into contact with the bottom of the rotating bridge, the gas inside it reaches the clamping airbag along the exhaust pipe. The volume of the clamping airbag increases to a maximum value and the internal air pressure value is greater than the preset pressure value of the pressure valve. The pressure valve opens, and the gas in the clamping airbag flows to the buffer airbag. The air pressure value detected by the air pressure sensor in the buffer airbag is greater than the set preset value. The pressure value detected by the pressure sensor on the top of the limit cross plate is greater than the set preset value. The controller controls the drive motor to reverse and drive the bracket to move away from the rotating bridge end.

[0013] The present invention has at least the following beneficial effects:

[0014] 1. This application arranges a central support part, an end support part and a top limit part. First, the rotating bridge is placed on the top of the central frame. When placed, the bottom of the rotating bridge contacts the top of the horizontal section of the support. Then, the two brackets are connected to the two ends of the central frame so that the top of the limiting cross plate contacts the side wall of the rotating bridge for support and limitation. Then, the first adjusting screw is rotated to drive the large suction cup to move until it contacts the bottom of the rotating bridge, supporting and limiting the bottom of both sides of the rotating bridge. Finally, the top plate is connected to the central frame through a connecting frame to limit the top of the rotating bridge. The structure is reasonable, and the frame combination fully supports and limits it, which not only effectively protects the rotating bridge, but also facilitates observation and monitoring by the staff.

[0015] 2. This application sets up a middle frame, a large suction cup, a supporting circular plate and a limiting horizontal plate and cooperates with each other. First, the rotating bridge is placed on the top of the middle frame. When placed, the bottom of the rotating bridge contacts the top of the supporting circular plate. Then, the two brackets are connected to the two ends of the middle frame, and the third adjusting screw is rotated to drive the limiting horizontal plate to adjust so that the top of the limiting horizontal plate contacts the side wall of the rotating bridge for support and limitation. Then, the first adjusting screw is rotated to drive the large suction cup to move until it contacts the bottom of the rotating bridge, supporting and limiting the bottom of both sides of the rotating bridge. Finally, the top plate is connected to the middle frame through the connecting frame, and the top of the rotating bridge is limited by the cooperation of the second adjusting screw, the limiting top plate, the positioning plate, the contact plate and the flexible protrusion. The structure is reasonable, and the frame combination fully supports and limits, which not only effectively protects the rotating bridge, but also facilitates observation and monitoring by staff.

[0016] 3. This application places the rotating bridge on top of the large suction cup by setting up a large suction cup, a small suction cup, a first channel, a second channel, a limiting horizontal plate, a buffer airbag and a supporting airbag, and the large suction cup is in elastic contact with the rotating bridge. At the same time, the gas in the large suction cup flows along the first channel to the supporting airbag, and the supporting airbag is in elastic contact with the bottom of the rotating bridge. The limiting horizontal plate is in close contact with the side wall of the rotating bridge, and the snap-on airbag is snapped onto both sides of the rotating bridge. Therefore, the rotating bridge achieves elastic connection during transportation, thereby effectively improving the supporting and buffering protection performance of the rotating bridge, and is more adaptable.

[0017] 4. The present application sets up a buffer airbag, a clamping airbag, a pressure valve, a pressure sensor and an air pressure sensor to cooperate with each other. When the transport vehicle starts, the rotating bridge squeezes the limit cross plate and the buffer airbag, and the gas in the buffer airbag flows along the clamping airbag and the exhaust pipe to the support airbag, and the support airbag increases the supporting force on the bottom of the rotating bridge. At the same time, the pressure value detected by the pressure sensor is greater than the preset value, and the air pressure value detected by the air pressure sensor is less than the preset value. The controller controls the drive motor to rotate forward to drive the bracket to rotate toward the end of the rotating bridge, and the supporting force of the limiting crossbar on the rotating bridge is increased. When the transport vehicle makes a sharp turn, the rotating bridge further squeezes the large suction cup, and then squeezes the small suction cup so that the gas inside the small suction cup flows along the second channel to the support airbag. The side of the support airbag rises, thereby increasing its friction with the bottom of the rotating bridge. At the same time, the excess gas reaches the clamping airbag along the support airbag, and the volume of the clamping airbag increases and supports and limits the side wall of the rotating bridge, thereby preventing it from tilting. When the vehicle passes over a bumpy road, the center The frame drives the first adjusting screw and the supporting circular plate to move upward, and the small suction cup squeezes and contacts the side wall of the rotating bridge, and the internal gas flows along the second channel to the supporting airbag, and the gas in the supporting airbag flows to the clamping airbag. The air pressure in the clamping airbag is greater than the preset pressure value of the pressure valve, the pressure valve opens, and the gas in the clamping airbag reaches the buffer airbag. At the same time, the pressure value detected by the pressure sensor is greater than the set preset value. The air pressure value detected by the air pressure sensor is greater than the set preset value. The controller controls the driving motor to reverse and drive the bracket to rotate away from the rotating bridge end. The volume of the buffer airbag increases and supports and limits the side plate of the rotating bridge. The device can effectively squeeze, protect and fix rotating bridges of various models and sizes, with good support effect and excellent buffering and shock absorption effect. At the same time, when the transport vehicle drives the rotating bridge to start sudden braking, make sharp turns or bumpy roads, the coordinated movement of each component is adaptively adjusted respectively, thereby fully achieving the best buffering protection for problems arising during various transportation processes, improving the adaptability of the device, and ensuring the reasonable and efficient operation of the device.

The bottom of each support circular plate 104 is connected to the top of the horizontal section of the support member 105 through a fixing rod, and the top of each support plate 110 is provided with an elastic protrusion 109. The setting of the support circular plate 104 facilitates contact with the bottom of the rotating bridge 4.

[0037] A bottom frame 108 is provided at the bottom of the middle frame 101. The top of the bottom frame 108 is fixedly connected to the bottom bolts of the middle frame 101. One end of the horizontal section of the connecting frame 301 is fixedly connected to the bottom bolts of one side of the bottom frame 108. Through the setting of the bottom frame 108, the position of the middle frame 101 is raised.

[0038] The top of the bridge 302 is fixed with a plurality of adjusting screws, each of which is connected to the top of the bridge 302. The adjusting screws 306 are connected to the top of the bridge 302 by a plurality of adjusting screws. The adjusting screws 306 are connected to the top of the bridge 302 by a plurality of adjusting screws.

[0039] A rotating circular plate is provided at one end of the second adjusting screw away from the top plate 302, and a plurality of turning handles 304 are provided on the outer ring of the rotating circular plate. A plurality of anti-slip grooves are provided on the outer ring of each turning handle 304. The setting of the turning handle 304 facilitates the rotation of the rotating circular plate and the second adjusting screw.

[0040] A third adjusting screw is rotatably provided at the bottom center of the limiting horizontal plate 202, one end of which passes through the bracket 201 through a screw sleeve. Round rods are provided on both sides of the bottom of the limiting horizontal plate 202, one end of which passes through the top of the bracket 201 through a sliding sleeve. The fixing part 5 includes a fixing plate 501 fixedly connected to the bottom bolt of the bottom frame 108 and two fixed side frames 502 symmetrically arranged on both sides of the top of the fixing plate 501. Several supporting diagonal rods 503 are provided on the opposite sides of the two fixed side frames 502.

When placing, the bottom of the swivel bridge 4 contacts the top of the supporting circular plate 104, so that the swivel bridge 4 is stably placed on the top of the middle frame 101.

The structure is reasonable, and the frame combination fully supports and limits the position, which can not only effectively protect the rotating bridge 4, but also facilitate observation and monitoring by the staff.

[0042] Second embodiment

[0043] Reference Figure 6-10 As can be seen from the first embodiment, the rotating bridge 4 is clamped and fixed on all sides when being transported by the device, especially through multiple adjustment screws for adjustment, so the adjustment accuracy is poor and the clamping effect is also poor. At the same time, when the vehicle starts or brakes suddenly, due to the inertia of the rotating bridge 4 itself, the rotating bridge 4 will exert a large force on the limiting horizontal plate 202, so long-term use will cause damage to the limiting horizontal plate 202 or the bracket 201; at the same time, when the transport vehicle passes a sharp turn, the rotating bridge 4 will turn accordingly and exert a large lateral pressure on the first adjusting screw on one side and the large suction cup 103 on the top under the action of centrifugal force, which will cause damage to the first adjusting screw under the action of this lateral pressure; and when reaching a bumpy road section, the transport vehicle will cause the rotating bridge 4 to vibrate when it is bumpy, and the lack of a shock absorbing device will affect the safety and integrity of the rotating bridge 4. In order to solve the above problems and ensure the stability and safety of the rotating bridge 4 during transportation, the rotating bridge device that is easy to monitor also includes a controller on one side of the top limit part 3, which electrically controls various electrical components.

[0044] A first channel 6 is provided inside the first adjusting screw, and the other end of the large suction cup 103 is connected to the first channel 6. A small suction cup 7 is provided inside the large suction cup 103 through multiple groups of support rods. The other end of the small suction cup 7 is connected to a second channel 8. The second channel 8 is located inside the first channel 6. Therefore, when the rotating bridge 4 is placed on the top of the large suction cup 103, the rotating bridge 4 squeezes the large suction cup 103 and does not squeeze the small suction cup 7. The gas in the large suction cup 103 is discharged along the first channel 6. When the rotating bridge 4 moves to one side under the action of centrifugal force, the rotating bridge 4 will further Squeeze the large suction cup 103 on one side, and the rotating bridge 4 will be squeezed with the small suction cup 7 and the gas therein will be discharged along the second channel 8, thereby realizing elastic protection and phased and adsorption fixing of the rotating bridge 4 when encountering a sharp turn during transportation, with stronger adaptability and a more compact structure. At the same time, the large suction cup 103 is connected to the small suction cup 7 by a support rod, which will not affect the supporting effect of the small suction cup 7, and can also ensure the ventilation performance of the large suction cup 103 and the first channel 6, avoiding problems such as blockage or poor gas circulation.

[0045] A buffer airbag 13 is provided on the side of the limiting horizontal plate 202 close to the rotating bridge 4. The buffer airbag 13 is symmetrically connected to two groups of snap-on airbags 11 on the side close to the rotating bridge 4 through a pressure valve 12. The contact surfaces of the snap-on airbag 11 and the buffer airbag 13 with the rotating bridge 4 are different. As can be seen from the figure, the buffer airbag 13 contacts the bottom of the left and right ends of the rotating bridge 4, and the snap-on airbag 11 is located on the side of the buffer airbag 13 close to the rotating bridge 4. At the same time, the snap-on airbag 11 contacts the front and rear sides of the rotating bridge 4. Therefore, when the volume of the snap-on airbag 11 increases, the front and rear sides of the rotating bridge 4 will be snapped. , thereby hindering the rotation deviation of the rotating bridge 4, an air pressure sensor is provided in the buffer airbag 13, and the air pressure sensor is used to detect the air pressure value inside the buffer airbag 13, and a pressure sensor is provided on the top of the limiting horizontal plate 202, and the pressure sensor is used to detect the pressure value on the top of the limiting horizontal plate 202. The snap-fit airbag 11 and the two side surfaces of the rotating bridge 4 close to the first adjusting screw are snapped into each other, and the supporting airbag 9 is in contact with the side of the rotating bridge 4 close to the limiting horizontal plate 202. This design can provide all-round buffering protection for the rotating bridge 4 with the help of the snap-fit airbag 11 and the supporting airbag 9.

[0046] The support circular plate 104 matches the position of the first adjusting screw. Therefore, it can be seen from the figure that the multiple groups of first screws in the same row correspond to a support circular plate 104 on one side. A support airbag 9 is provided on the top of the support circular plate 104. The support airbag 9 is connected to the first channel 6 and the second channel 8 that are adjacent to the large suction cup 103. Therefore, when the large suction cup 103 is squeezed, the gas inside it will flow to the support airbag 9 along the first channel 6. At this time, the volume of the support airbag 9 increases and is squeezed and contacted with the bottom of the rotating bridge 4, thereby realizing elastic contact between the support airbag 9 and the rotating bridge 4. The multiple groups of support airbags 9 are interconnected through the exhaust pipe 10. The other end of the exhaust pipe 10 located near both sides of the bracket 201 is connected to the clamping airbag 11. Therefore, when the small suction cup 7 is squeezed, the gas inside it flows along the second channel 8 to the inside of the support airbag 9. Since the volume of the top of the support airbag 9 has reached the maximum value under the squeezing action of the bottom of the rotating bridge 4, this part of the gas will be discharged into the clamping airbag 11 along the exhaust pipe 10.

[0047] During use, in the initial state, the openings of the large suction cup 103 and the small suction cup 7 are both in the open state. At this time, the outside air can circulate arbitrarily along the first channel 6 and the second channel 8. The large suction cup 103 and the small suction cup 7 are not squeezed, and the support airbag 9 on the top of the support circular plate 104 is synchronously in the initial compression state. At this time, the first adjusting screw is adjusted according to the approximate size of the rotating bridge 4, and then the height of the multiple groups of large suction cups 103 is adjusted so that it can fully support the rotating bridge 4. At the same time, the third adjusting screw is adjusted so that the limiting horizontal plate 202 on the top of the third adjusting screw can contact the side of the rotating bridge 4, and then the rotating bridge 4 is placed on the top of the large suction cup 103. The rotating bridge 4 squeezes the large suction cup 103, and the gas in the large suction cup 103 circulates along the first channel 6 to the inside of the support airbag 9. The volume of the support airbag 9 increases under the action of the gas and is squeezed against the bottom of the rotating bridge 4. Contact, with the help of the elastic force driven by the supporting airbag 9 itself, not only can it ensure that the supporting airbag 9 is in close contact and support with the bottom of the rotating bridge 4, avoiding the problem of poor adjustment accuracy and uneven support of the rotating bridge 4, but also improving the adjustment accuracy and ensuring the all-round fixation of the rotating bridge 4 without dead angles. At the same time, with the help of the elastic adsorption and fixing effect of the large suction cup 103, not only can the fixing effect of the rotating bridge 4 be improved, but the deformability of the large suction cup 103 can also be used to adaptively adjust and change the rotating bridge 4, ensuring that the large suction cup 103 can wrap the rotating bridge 4 in all directions, avoiding gaps when adjusting the height of the large suction cup 103 and causing its unstable support for the rotating bridge 4. Finally, by adjusting the second adjusting screw in the top limit part 3, the second adjusting screw drives the bottom contact plate 308 to contact the top of the rotating bridge 4 to limit its top.

[0048] After the initial loading is completed, the pressure sensor on the top of the limiting cross plate 202 detects the pressure value, and the air pressure sensor inside the supporting airbag 9 detects the air pressure value. The pressure value and the air pressure value are both conventional stable values. When the transport vehicle starts or brakes suddenly, the analysis is mainly based on the starting of the transport vehicle. Due to the inertia problem of the rotating bridge 4 itself, the rotating bridge 4 will squeeze the limiting cross plate 202 backward. At the same time, since the third adjusting screw and the bracket 201 are vertically arranged, the third adjusting screw will be squeezed with the bracket 201 after long-term use, causing damage to it. When the limiting cross plate 202 is squeezed, the pressure value detected by its pressure sensor increases. At the same time, when the limiting cross plate 202 is squeezed, the supporting airbag 9 on one side is squeezed, and the air pressure value detected by the air pressure sensor decreases. Figure 9As shown, at this time, the controller controls the drive motor to start forward rotation and then drives the bracket 201 to rotate toward the end of the rotating bridge 4. At this time, the buffer airbag 13 on the side of the limiting horizontal plate 202 is subjected to increased squeezing pressure, and the gas inside the buffer airbag 13 flows along the pressure valve 12 to the clamping airbag 11. The volume of the clamping airbag 11 increases and protects both sides of the rotating bridge 4. At the same time, the excess gas in the clamping airbag 11 continues to flow in the opposite direction along the exhaust pipe 10 to the support airbag 9 near the side of the bracket 201. The support force of the support airbag 9 on the bottom of the rotating bridge 4 on this side is increased, and the friction between the top of the support airbag 9 and the rotating bridge 4 is increased, thereby preventing the rotating bridge 4 from moving backward under the action of its own inertia and detaching from the top of the support airbag 9. At the same time, with the help of the rotation of the bracket 201, the angle between the third adjusting screw and the side of the rotating bridge 4 can be increased to ensure that the supporting force of the limiting horizontal plate 202 on one side of the rotating bridge 4 is sufficient, thereby preventing the rotating bridge 4 from damaging the limiting horizontal plate 202 and the third adjusting screw in the reverse direction.

[0049] The transport vehicle starts and begins to transport the vehicle stably. When the vehicle encounters a sharp turn, the transport vehicle and the loaded rotating bridge 4 have centrifugal force under the action of the centrifugal force. Therefore, the rotating bridge 4 will further squeeze the large suction cup 103 on one side under the action of the centrifugal force. At this time, the rotating bridge 4 further squeezes the small suction cup 7. The small suction cup 7 can not only improve the supporting force and protective fixing effect on this side of the rotating bridge 4, but also avoid damage to the first adjusting screw. At the same time, the gas in the small suction cup 7 will flow along the second channel 8 to the inside of the supporting airbag 9, and the supporting airbag 9 will further support the bottom of the rotating bridge 4 upward, and the rotating bridge 4 will be tilted. The supporting force on the bottom of the centrifugal outer side of the bridge 4 increases, and synchronously, the squeezing force on the large suction cup 103 on the centrifugal inner side of the rotating bridge 4 decreases when the rotating bridge 4 rotates, and the squeezing force on the inside of the large suction cup 103 decreases, and the gas in the supporting airbag 9 at the corresponding position will flow back to the large suction cup 103 on this side, and the supporting force of the supporting airbag 9 on the centrifugal inner side of the rotating bridge 4 is reduced. Therefore, when the rotating bridge 4 turns, there is a difference in the supporting force of the supporting airbags 9 distributed at the bottom of the rotating bridge 4. Under the action of this difference, the centrifugal movement of the bottom of the rotating bridge 4 to the outside will be hindered, further improving its stability when turning.

[0050] Synchronously, when the rotating bridge 4 turns, the amount of gas in the support airbag 9 on the centrifugal outer side increases, and the support airbag 9 is already in close contact with the bottom of the rotating bridge 4. The friction between the support airbag 9 and the rotating bridge 4 on this side increases, but the volume of the support airbag 9 does not increase too much. Therefore, the gas in the support airbag 9 will reach the clamping airbag 11 along the exhaust pipe 10. The air pressure only includes the gas in the small suction cup 7. Therefore, the air pressure is less than the opening preset value of the pressure valve 12. The pressure valve 12 does not open, and the gas only remains in the clamping airbag 11. The volume of the snap-on airbag 11 increases under the action of the gas. Since the snap-on airbag 11 is located on both sides of the rotating bridge 4 and on the same side as the large suction cup 103, under the action of this force, the support area of the snap-on airbag 11 on the centrifugal outer side of the rotating bridge 4 increases, and the corresponding supporting force of the snap-on airbag 11 on the centrifugal outer side of the rotating bridge 4 increases, thereby increasing the supporting and protecting effect of the rotating bridge 4, further avoiding the side bending of the rotating bridge 4 when passing a curve, thereby causing damage to the entire device and even the transport vehicle, thereby causing major safety accidents.

[0051] When the vehicle travels on a bumpy road section, the front end of the vehicle first contacts the bumpy raised road. At this time, the transport vehicle transfers the raised road section to the middle frame 101 end with the help of the bottom frame 108. The middle frame 101 transfers the raised bump to the support circular plate 104 end. The support circular plate 104 further moves upward and squeezes the support airbag 9. The top of the support airbag 9 and the bottom of the rotating bridge 4 squeeze each other to cushion the impact and avoid hard contact and thus causing extrusion damage to the bottom of the rotating bridge 4. At the same time, when the middle frame 101 moves upward, it will synchronously drive the first adjusting screw to move upward with the help of the side plate 102. When the first adjusting screw moves upward, The large suction cup 103 is further squeezed and contacted with the side wall of the rotating bridge 4, thereby driving the small suction cup 7 to be squeezed with the rotating bridge 4, so that the gas in the small suction cup 7 flows along the second channel 8 to the supporting airbag 9. Since the top of the supporting airbag 9 is squeezed synchronously with the bottom of the rotating bridge 4, the volume of the supporting airbag 9 does not increase, and the original gas in the supporting airbag 9 and the gas flowing along the second channel 8 need to flow along the exhaust pipe 10 to the clamping airbag 11. Therefore, the volume of the clamping airbag 11 increases and clamps the two sides of the rotating bridge 4. At the same time, since the gas in the clamping airbag 11 at this time mainly comes from the small suction cup 7 and the supporting airbag 9, the clamping airbag 1 1 is greater than the pressure preset value set by the pressure valve 12, the pressure valve 12 opens, and the excess gas in the card airbag 11 flows into the buffer airbag 13. The air pressure value detected by the air pressure sensor in the buffer airbag 13 is greater than the set preset value. At the same time, since the middle frame 101 moves upward, the middle frame 101 will drive the bracket 201 and the limit cross plate 202 to rise at the same time, and then the pressure value detected by the pressure sensor on the top of the limit cross plate 202 is greater than the set preset value. In order to avoid damage caused by close compression between the limit cross plate 202 and the side of the rotating bridge 4 when passing through a bumpy road section, when the pressure value detected by the pressure sensor is greater than the set preset value When the air pressure value detected by the air pressure sensor is greater than the preset value, the driving motor starts to reverse and drives the bracket 201 to rotate away from the end of the rotating bridge 4. The distance between the limiting horizontal plate 202 and the side wall of the rotating bridge 4 continues to increase. This increase not only avoids the close squeezing contact between the limiting horizontal plate 202 and the side wall of the rotating bridge 4, but also leaves room for the volume increase of the buffer airbag 13, thereby ensuring that the buffer airbag 13 can increase in volume and support and protect the side wall of the rotating bridge 4, and changes the original hard squeezing contact of the limiting horizontal plate 202 into an elastic wrapping fixation, thereby improving its support effect and ensuring the stability and damagelessness of the rotating bridge 4 when passing through bumpy sections.

[0052] The device can effectively squeeze, protect and fix rotating bridges 4 of various models and sizes, with good supporting effect and excellent buffering and shock absorption effect. At the same time, when the transport vehicle drives the rotating bridge 4 to start sudden braking, make sharp turns or go through bumpy roads, it adaptively adjusts the coordinated movement of each component, thereby fully achieving the best buffering protection for problems arising during various transportation processes, improving the adaptability of the device, and ensuring the rational and efficient operation of the device.
