Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary tooling for ship segment construction, and more specifically, to a turning-over device and a turning-over method for ship thin plate segments. Background Art

[0002] During the shipbuilding process, thin plate segmented structures such as double bottom segments and segments with decks as the base surface usually adopt the reverse construction method, that is, the longitudinal and transverse frames are first welded on one side to form a reverse structure. Since the position of the segment during construction is opposite to its actual installation position, it must be turned 180° after the welding process is completed for subsequent welding and assembly.

[0003] At present, the commonly used turning method is to transport the thin plate segments to the turning area by welding lifting lugs with a Self-Propelled Modular Transporter (SPMT trolley), and then use a crane to lift and turn them in the air. In this method, the installation and removal of the lifting lugs is time-consuming and increases the construction cost. During the turning process, when the thin plate segments pass the critical turning point, they will produce a large downward acceleration due to the influence of gravity, which can easily cause the thin plate segments with insufficient strength to deform. At the same time, the crane operation is complicated, which increases the danger of the operation.

[0004] The existing thin plate segment turning operation not only requires a lot of manual work, but also the connection between the turning device and the thin plate segment production line is not tight enough, making it difficult to achieve efficient assembly line production. To solve these problems, a safer, more efficient and hoist-free turning device is urgently needed to reduce the deformation risk of thin plate segments, improve production efficiency, and ensure the safety and reliability of the entire turning process. Summary of the invention

[0005] Aiming at the problems of segment deformation and discontinuity of production line caused by the existing thin plate segment turning process, the present invention proposes a clamping thin plate segment turning device to reduce manual participation and crane resource occupation in the thin plate segment turning process, thereby improving operation quality, operation efficiency and safety.

[0006] Another object of the present invention is to provide a method for turning over thin plate segments to improve work quality, work efficiency and safety.

[0007] The technical solution adopted to achieve the purpose of the present invention is:

[0008] A clamping type thin plate segmented turning device, comprising a supporting mechanism, a turning mechanism, a turning driving mechanism and a limiting mechanism;

[0009] The supporting mechanism is used to support the flipping mechanism and the limiting mechanism;

[0010] The flipping mechanism includes a flipping bracket, a flipping clamping unit and a pallet lifting and lowering driving mechanism; the flipping clamping unit includes two pallets, each of which includes a frame surrounded by a fixed beam, two sections of telescopic movable beams and two longitudinal beams, and a plurality of supporting beams connecting the frame, and an empty slot corresponding to the SPMT trolley is provided in the frame, and the position corresponding to the empty slot when the telescopic movable beam is in a retracted state is an opening for the SPMT trolley to enter / exit the flipping area, and the frame is a complete closed structure when the telescopic movable beam is in an extended state; the two pallets are arranged antisymmetrically, and the fixed beam in one pallet is arranged opposite to the telescopic movable beam of the other pallet; a pallet support for supporting the deadweight of the pallet is installed on the frame; the pallet lifting and lowering driving mechanism is used to drive the two pallets to achieve the clamping and release of thin plate segments;

[0011] The limiting mechanism is installed on the frame of the tray and is used to lock the segmented state of the two trays clamping the thin plates during the turning process.

[0012] The limiting mechanism includes a locking member, a limiting pin and a limiting plug respectively installed at the relative positions of the two pallets; the locking member is composed of a driving motor, a driving connecting rod, a spring connecting rod and a locking pin; the driving motor is installed inside the pallet and fixedly connected to the pallet, one end of the driving connecting rod is fixedly connected to the driving motor, and the other end is connected to the locking pin through the spring connecting rod; in the locked state, the limiting plug is inserted into the limiting pin, and the locking pin is inserted into the socket on the limiting plug, which is used to lock the two pallets in the segmented state of clamping the thin plate during the flipping process.

[0013] It also includes a rotary releaser for realizing automatic unlocking of the limit mechanism, the rotary releaser includes a cylindrical container, a damping fluid, a metal rod and two sensors; the damping fluid fills the interior of the cylindrical container, the metal rod is vertically placed inside the cylindrical container and immersed in the damping fluid; the length of the metal rod is less than the height of the cylindrical container, and under the action of gravity and the damping fluid, the metal rod takes a certain amount of time to move to the lower end of the cylindrical container; the two sensors are respectively arranged at both ends of the cylindrical container, and when the metal rod reaches the lower end of the cylindrical container, the corresponding sensor is triggered, and the drive motor is controlled to work through the output signal of the sensor to realize automatic unlocking of the limit mechanism.

[0014] It also includes a distance measuring device, which is used to measure the distance between the two trays, and control the limiting mechanism to be locked or unlocked according to the distance between the two trays measured by the distance measuring device.

[0015] The flip bracket includes two X-shaped rotating brackets with the same structure; the pallet lifting drive mechanism includes four sets of winch mechanisms installed on the flip bracket, and each two sets of winch mechanisms pull the opposite ends of two pallets through traction rope guide wheels and multiple pallet traction ropes; the pallet positioning columns are fixedly connected to the corresponding X-shaped rotating brackets, and the two ends of each pallet are slidably connected to the corresponding pallet positioning columns; the thickness of each pallet is less than the height of the SPMT trolley; the pallet positioning column provides a track for the pallet to move in the height direction, and the pallet traction rope controls the vertical lifting and lowering of the pallet on the pallet positioning column.

[0016] There are two sets of distance measuring devices, which are respectively located on both sides of the flip bracket; each set of the distance measuring device includes a laser transmitter / receiver and a laser reflector.

[0017] The support mechanism is composed of two A-shaped support frames with the same structure, which are arranged opposite to each other and fixedly connected to the ground at the bottom; a rotating pair is installed on the top of each A-shaped support frame, and the flip driving mechanism is connected to the X-shaped rotating bracket through the rotating pair.

[0018] The rotary releaser is vertically installed on the side of the driving motor and is placed inside the tray together, and the height of the cylindrical container is similar to that of the driving motor.

[0019] A turning method using the clamping thin plate segmented turning device comprises the following steps:

[0020] (1) Two SPMT trolleys carry the thin plate segments to the turning area; the telescopic movable crossbeam of the pallet at the lower end is retracted to form an opening for the trolley to enter the turning area. The pallet is lower than the SPMT trolley at the lowest point, and the SPMT trolley uses the height difference to carry the thin plate segments into the pallet area; the telescopic movable crossbeam of the pallet is extended to close the opening, and the pallet frame at the lower end is a complete closed structure;

[0021] (2) The winch mechanism is started, and the two pallets are driven by the pallet traction rope. The two ends of the upper pallet slide down along the corresponding pallet positioning columns, and the two ends of the lower pallet slide along the corresponding pallet positioning columns to lift the thin plate segments. The two pallets move to the middle of the flip bracket, so that the relative distance between the upper and lower pallets is minimized. The two pallets clamp the thin plate segments, and at the same time, as the pallets move, the limit plugs are inserted into the limit pins;

[0022] (3) The distance measuring device monitors the relative distance between the two pallets in real time; when the relative distance remains unchanged for a period of time, the distance measuring device transmits a signal to the locking member, and the locking pin extends out and inserts into the jack at the corresponding position of the limit plug, thereby completing the locking of the limit mechanism;

[0023] (4) The flip drive mechanism drives the flip bracket and its components and thin plates to rotate 180° in sections;

[0024] (5) After the flipping mechanism is stabilized, the metal rod in the rotary releaser moves to the lower end of the cylindrical container, triggering the corresponding sensor; the sensor transmits a signal to the drive motor in the locking member, and the locking pin is retracted, completing the unlocking of the limit mechanism;

[0025] (6) The winch mechanism pulls up the upper pallet and lowers the lower pallet. The lower pallet carries the thin plate segments and descends. The lower pallet slowly descends to the lowest point. The weight of the thin plate segments is borne by the SPMT trolley after the height of the lower pallet is lower than the height of the SPMT trolley. The telescopic movable crossbeam contracts to form an opening for the trolley to drive out of the flipping area. The SPMT trolley carries the flipped thin plate segments and leaves the pallet area.

[0026] After the SPMT trolley carries the turned-over thin plate segment out of the pallet area, the turning-over process of the next thin plate segment is immediately carried out.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The thin plate segment turning device of the present invention uses two pallets to clamp the thin plate segments. Through the reasonable design of the turning device, no crane or lifting lugs are required in the whole process of turning over the thin plate segments, and no cutting or grinding of the lifting lugs is required, which can avoid structural deformation of the thin plate segments during the turning process, reduce manual participation and occupation of crane resources in the process of turning over the thin plate segments, improve operation quality, and increase operation safety.

[0029] 2. A rotary releaser and a limiting mechanism are provided in the thin plate segmented turning device of the present invention, and the action of the limiting mechanism can be controlled according to the signal provided by the rotary releaser to realize automatic unlocking of the limiting mechanism, thereby ensuring that the limiting mechanism can be released in time after the rotation is completed, thereby greatly improving the operating efficiency and safety of the turning device.

[0030] 3. In the thin plate segmented turning device of the present invention, the locking member in the limit mechanism is composed of a driving motor, a driving connecting rod, a spring connecting rod and a locking pin. The locking member is controlled by rotating the releaser to drive the connecting rod to extend and retract, thereby realizing the extension and retraction of the locking pin. When the locking pin is extended, if it does not find a suitable socket for matching, the spring connecting rod has a buffering effect, which can ensure that the locking pin will not be damaged, thereby ensuring the safety and stability of the turning operation.

[0031] 4. In the thin plate segment flipping device of the present invention, the cooperation of the limit plug, limit pin and locking member in the limit mechanism ensures that the relative displacement of the two pallets remains unchanged during the flipping process of the thin plate, and at the same time ensures that even if the thin plate segment slides, the thin plate segment will not separate from the flipping bracket, thereby improving the safety of production operations.

[0032] 5. The thin plate segment turning device of the present invention does not need to be reset after completing a thin plate segment turning, and can immediately carry out the next turning operation, thereby reducing the segment secondary transportation caused by the thin plate segment turning, effectively reducing time consumption and improving work efficiency.

[0033] 6. The thin plate segmented turning device of the present invention can realize automatic locking and unlocking operations according to the clamping condition of the pallet and the turning completion condition, thereby improving the automation level of the entire turning process.

[0034] 7. The thin plate segment turning method of the present invention is started and ended by the SPMT trolley for transportation, and there is no need to move the SPMT trolley during the turning process, which is consistent with the existing thin plate segment manufacturing process and is closely connected with the upstream and downstream processes.

DETAILED DESCRIPTION

[0051] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the following description is a detailed description of the embodiments, but it is not an exhaustive description of all possible implementation methods. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0052] The schematic diagram of the clamping type thin plate segment turning device of the present invention is as follows Figure 1-Figure 13 As shown, it includes a supporting mechanism, a turning mechanism, a turning drive mechanism and a limiting mechanism. The turning drive mechanism is used to realize the turning of the thin plate segments.

[0053] The support mechanism is used to support the flip mechanism and the limit mechanism. In this embodiment, the support mechanism is composed of two A-shaped support frames 4 with the same structure, and the two A-shaped support frames 4 are arranged opposite to each other and the bottoms are fixedly connected to the ground.

[0054] The flipping mechanism includes a flipping bracket 3, a flipping clamping unit and a pallet lifting and lowering driving mechanism. The flipping and clamping unit includes two pallets 6, each of which includes a frame surrounded by a fixed beam 16, two sections of telescopic movable beams 8 and two longitudinal beams, and a plurality of supporting beams connecting the frame. An empty slot corresponding to the SPMT trolley is provided in the frame. When the telescopic movable beam is in a retracted state, the position corresponding to the empty slot is the opening for the SPMT trolley to enter / exit the flipping area. When the telescopic movable beam is in an extended state, the frame is a complete closed structure. The two pallets 6 are arranged in an anti-symmetrical manner, and the fixed beam 16 in one pallet is arranged opposite to the telescopic movable beam 8 of the other pallet. A pallet support 12 for supporting the deadweight of the pallet 6 is installed on the frame. In this embodiment, the pallet support 12 is placed at the bottom of the pallet 6, and a conventional cross-shaped pallet support is adopted. The pallet lifting and lowering driving mechanism is used to drive the two pallets 6 to achieve the clamping and release of the thin plate segments.

[0055] In this embodiment, the flip bracket 3 includes two X-shaped rotating brackets with the same structure. Fig.10 The diagram shows the connection between the pallet lifting drive mechanism and the pallet. The pallet lifting drive mechanism includes four groups of winch mechanisms 9 installed on the flip bracket 3. Each two groups of winch mechanisms pull the opposite ends of two pallets 6 through the traction rope guide wheel 13 and multiple pallet traction ropes 10. The pallet traction rope 10 is connected to the pallet through the pallet joint 11. The two ends of the pallet positioning column 7 are fixedly connected to the corresponding X-shaped rotating bracket, and the two ends of each pallet 6 are slidably connected to the corresponding pallet positioning column 7; the thickness of each pallet 6 is less than the height of the SPMT trolley 1. The pallet positioning column 7 mainly provides a track for the pallet 6 to move in the height direction. The pallet traction rope 10 mainly controls the vertical lifting and lowering of the pallet 6 on the pallet positioning column 7. The two pallets 6 move to the middle of the pallet positioning column 7 at the same time to achieve the clamping of the thin plate segment. The two pallets 6 move to the two ends of the pallet positioning column 7 at the same time to achieve the release of the thin plate segment.

[0056] In this embodiment, a rotating pair 5 is installed on the top of each A-shaped support frame 4, and the flip driving mechanism is connected to the X-shaped rotating bracket through the rotating pair 5, driving the X-shaped rotating bracket and the components and thin plates thereon to flip in sections. The flip driving mechanism can adopt a structure form such as electric drive and hydraulic drive.

[0057] The limiting mechanism is installed on the frame of the tray 6 and is used to lock the state of the two trays 6 clamping the thin plate segment 2 during the flipping process.

[0058] The limiting mechanism is as follows Fig.11As shown, in this embodiment, the limiting mechanism includes a locking member, a limiting pin 14-1 and a limiting plug 14-2 respectively installed at the relative positions of the two trays 6. The locking member is composed of a driving motor 14-3, a driving connecting rod 14-4, a spring connecting rod 14-5 and a locking pin 14-6. The driving motor 14-3 is installed inside the tray and fixedly connected to the tray 6. One end of the driving connecting rod 14-4 is fixedly connected to the driving motor 14-3, and the other end is connected to the locking pin 14-6 through the spring connecting rod 14-5. In the locked state, the limiting plug 14-2 is inserted into the limiting pin 14-1, and the locking pin 14-6 is inserted into the jack on the limiting plug, which is used to lock the state of the two trays 6 clamping the thin plate segment 2 during the flipping process. In this embodiment, the sockets on each of the limit plugs 14-2 are arranged in two rows, and there are two drive rods 14-4, spring links 14-5 and locking pins 14-6 in each locking member, which are arranged in parallel, and the spacing between the two locking pins 14-6 is consistent with the spacing between the sockets on the limit plug 14-2. The drive motor 14-3 controls the extension and retraction of the drive link 14-4, thereby realizing the extension and retraction of the locking pin 14-6. When the locking pin 14-6 is extended, if no suitable socket is found for matching, the spring link 14-5 has a buffering effect, which can ensure that the locking pin will not be damaged. The two locking pins are horizontally connected to the same drive motor through the drive link and the spring link, and together constitute a complete locking member. In this embodiment, there are six sets of the limiting mechanisms in each pallet, which are respectively installed on one side of the fixed beams of the two pallets. Through the cooperation of the corresponding limiting plugs, limiting pins and locking parts, the relative displacement of the two pallets remains unchanged during the flipping of the thin plates, and even if the thin plate segments slide, the thin plate segments will not separate from the flipping mechanism.

[0059] It also includes a rotary releaser 14-7 for realizing automatic unlocking of the limiting mechanism. In this embodiment, the rotary releaser is as follows Fig.13As shown, it includes a cylindrical container 14-7-1, a damping fluid 14-7-2, a metal rod 14-7-3 and two sensors 14-7-4. The damping fluid 14-7-2 fills the inside of the cylindrical container 14-7-1, and the metal rod 14-7-3 is vertically placed inside the cylindrical container 14-7-1 and immersed in the damping fluid 14-7-2. The length of the metal rod 14-7-3 is less than the height of the cylindrical container 14-7-1. Under the action of gravity and the damping fluid, the metal rod 14-7-3 takes a certain amount of time to move to the lower end of the cylindrical container. The two sensors 14-7-4 are respectively arranged at the two ends of the cylindrical container 14-7-1. When the metal rod 14-7-3 reaches the lower end of the cylindrical container, the corresponding sensor 14-7-4 is triggered, and the drive motor 14-3 is controlled to work through the signal of the sensor 14-7-4. In this embodiment, in order to reduce the possibility of collision damage, the rotary releaser 14-7 is preferably installed vertically on the side of the drive motor 14-3, and placed together inside the tray 6, and the height of the cylindrical container 14-7-1 is similar to the height of the drive motor 14-3. The rotary releaser 14-7 can control the operation of the drive motor 14-3 through the signal transmitted by the sensor, thereby driving the locking pin 14-6 to retract, realize the automatic unlocking of the limit mechanism, and ensure that the limit mechanism can be released in time after the rotation is completed and stabilized, which greatly improves the efficiency and safety of the turning device. The rotary releaser 14-7 is set according to the needs of use. One rotary releaser can control one limit mechanism, or one rotary releaser can control multiple limit mechanisms.

[0060] In order to automatically realize the locking and unlocking of the limit mechanism, a distance measuring device 15 is also included. The distance measuring device 15 is used to measure the relative distance between the two trays 6, and the limit mechanism is controlled to be locked or unlocked according to the distance between the two trays measured by the distance measuring device 15. In this embodiment, there are two sets of distance measuring devices 15, which are respectively located on both sides of the flip bracket 3. The layout diagram of the distance measuring device is shown in FIG. Fig.12 As shown, each set of the distance measuring device includes a laser transmitter / receiver 15-1 and a laser reflector 15-2. The laser transmitter / receiver 15-1 and the laser reflector 15-2 are respectively arranged vertically at both ends of the center line of the tray 6 along the length direction. The limit mechanism 14 and the distance measuring device 15 cooperate to automatically realize the locking and unlocking of the limit mechanism, thereby improving the automation level of the thin plate turning device.

[0061] The size of the thin plate segment to be turned over in this embodiment is smaller than the size of the pallet and larger than the spacing between the telescopic movable crossbeams. The specific turning method is as follows:

[0062] (1) Transportation of thin plate segments: combined Figure 2 and Figure 3 , two SPMT trolleys carry the thin plate segments to the turning area; the telescopic movable crossbeam of the pallet at the lower end is retracted to form an opening for the trolley to enter the turning area. The pallet is lower than the SPMT trolley at the lowest point, and the SPMT trolley uses the height difference to carry the thin plate segments into the pallet area. Afterwards, the telescopic movable crossbeam of the pallet extends to close the opening, and the pallet frame at the lower end is a complete closed structure.

[0063] Specifically, before the thin plate segment 2 that needs to be turned over is transported to the pallet area, it is first necessary to ensure that the support mechanism is firmly placed on the ground, the height of the bottom pallet 6 from the ground is less than the height of the SPMT trolley 1 from the ground, and the two telescopic movable beams 8 on the bottom pallet 6 are retracted by hydraulic control. The gaps of the two telescopic movable beams 8 are the openings for the trolley to enter the turning area. At this time, the deadweight of the pallet 6 is borne by the pallet support 12 contacting the ground. The SPMT trolley 1 carries the thin plate segment 2 and uses the height difference between it and the bottom pallet 6 to drive into the empty slot of the pallet from the opening of the telescopic movable beam 8 of the bottom pallet 6. After the SPMT trolley 1 has completely entered the empty slot and the thin plate segment 2 is against the limit plug 14-2 of the bottom pallet 6, the telescopic movable beam 8 of the bottom pallet is extended by hydraulic control to close the opening, and the pallet frame at the lower end becomes a complete closed structure with the strength to bear the deadweight of the pallet and the weight of the thin plate segment 2. At this time, the weight of the thin plate segment 2 is still borne by the SPMT trolley 1.

[0064] (2) Clamping of thin plate segments: The winch mechanism is started and the two pallets are driven by the pallet traction rope. The two ends of the upper pallet slide down along the corresponding pallet positioning columns, and the two ends of the lower pallet slide along the corresponding pallet positioning columns to lift the thin plate segments. The two pallets move to the middle of the flip bracket to minimize the relative distance between the upper and lower pallets. The two pallets clamp the thin plate segments, and at the same time, the limit plug is inserted into the limit pin as the pallets move.

[0065] Specifically, the winch mechanism 9 located on both sides of the two X-shaped rotating brackets is started, and the pallet traction rope 10 is driven through the traction rope guide wheel 13 to control the upper and lower pallets 6 to move to the middle position of the pallet directional column 7. When the rising height of the bottom pallet 6 is higher than the height of the SPMT trolley 1, the bottom pallet 6 bears the responsibility. Figure 4 This is a three-dimensional schematic diagram of the pre-flipping of the thin plate in sections according to the present invention, combined with Figure 4 It can be seen that when the upper and lower trays 6 move to the middle of the tray directional column 7, the limit plugs 14-2 on the upper and lower trays are respectively inserted into the limit pins 14-1, and the two trays 6 clamp the thin plate segment 2 and apply a certain pressure.

[0066] (3) Locking of the limit mechanism: The distance measuring device monitors the relative distance between the two pallets in real time; when the relative distance remains unchanged for a period of time, the distance measuring device transmits a signal to the locking member, and the locking pin extends and inserts into the jack at the corresponding position of the limit plug, thereby completing the locking of the limit mechanism;

[0067] like Fig.12 and 13 As shown, after the thin plate is clamped in sections, the relative positions of the two trays 6 remain unchanged for a certain period of time. Based on this, the distance measuring device 15 sends a control signal, which is transmitted to the driving motor 14-3 of the locking member. The driving motor drives the locking pin 14-6 to extend and insert into the corresponding position of the limit plug 14-2, thereby completing the locking of the limit mechanism 14. It can be understood that at least one of the two locking pins 14-6 on a locking member is inserted into the limit plug 14-2, and the uninserted locking pin 14-6 will not affect itself and the limit plug 14-2 under the action of the spring connecting rod 14-5.

[0068] (4) Turning over of the thin plate segment: The turning drive mechanism drives the turning bracket and its components and the thin plate segment to rotate 180°.

[0069] refer to Figure 6 and Figure 7 ,in Figure 6 This is a 90° flipped three-dimensional diagram. Figure 7 It is a 180° flipped three-dimensional schematic diagram; preferably, two external motors drive the entire mechanism through the left and right rotating pairs 5 to rotate toward the thin plate segment 2 against one end of the thin plate limit plug 14-2. During the rotation, the two trays 6 continue to apply pressure to the thin plate segment 2. There is friction between the thin plate segment 2 and the trays 6. The thin plate limit plug 14-2 bears a certain pressure. When the mechanism rotates to 180°, the external motor stops driving the mechanism to rotate.

[0070] (5) Unlocking of the limit mechanism: After the flip mechanism is stabilized, the metal rod in the rotary releaser moves to the lower end of the cylindrical container, triggering the corresponding sensor; the sensor transmits a signal to the drive motor in the locking member, and the locking pin is retracted, completing the unlocking of the limit mechanism.

[0071] refer to Figure 8 and Fig.13 ,in Figure 8 This is a three-dimensional schematic diagram of the limiting mechanism of the present invention unlocking the thin plate and lowering the tray in sections. Fig.13It is a cross-sectional diagram of the rotary releaser; after the flipping mechanism clamps the thin plate and rotates 180°, after a period of time, the flipping mechanism returns to a stable state, and at the same time, the metal rod 14-7-3 inside the rotary releaser 14-7 contacts the sensor 14-7-4 at the bottom, transmits a signal to the locking member through the circuit, and the limit mechanism 14 is unlocked.

[0072] (6) Transporting the thin plate segments out: The winch mechanism pulls up the upper pallet and lowers the lower pallet. The lower pallet carries the thin plate segments and descends. The lower pallet slowly descends to the lowest point. The weight of the thin plate segments is borne by the SPMT trolley after the height of the lower pallet is lower than the height of the SPMT trolley. The telescopic movable crossbeam contracts to form an opening for the trolley to drive out of the flipping area. The SPMT trolley carries the flipped thin plate segments out of the pallet area.

[0073] Fig. 9 The three-dimensional schematic diagram of the flipping process is shown below. After the flipping process is completed, the winch mechanism 9 located on both sides of the two X-shaped rotating brackets is started, and the pallet traction rope 10 is driven by the traction rope guide wheel 13 to control the upper and lower pallets 6 to move to both sides of the directional column. The height of the bottom pallet 6 is lowered to be lower than the height of the SPMT trolley 1. The weight of the thin plate segment 2 is borne by the SPMT trolley 1, and the deadweight of the bottom pallet 6 is borne by the pallet support 12. The telescopic movable crossbeam 8 is retracted by hydraulic control. The notch of the two telescopic movable crossbeams 8 is the opening for the trolley to drive out of the flipping area. The SPMT trolley 1 carries the flipped thin plate segment 2 out of the pallet area to complete the flipping. At this time, the next thin plate segment can be flipped immediately, and the flipping steps are repeated as above.

[0074] The thin plate segment turning device and turning method of the present invention use a pallet to clamp the thin plate segment, which can avoid structural deformation of the thin plate segment during the turning process, improve the work quality, and increase the work safety. No crane or lifting lug is required in the whole turning process, and no cutting or grinding of the lifting lug is required, which reduces the manual participation and crane resource occupation in the turning process of the thin plate segment. And after completing a thin plate segment turning, there is no need to reset, and the next turning operation can be carried out immediately, which reduces the secondary transportation of the segments caused by the turning of the thin plate segment, effectively reduces time cost, and improves work efficiency.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
