Description

Technical Field

[0001] The present application relates to the technical field of railway tunnel construction equipment, and in particular to a magnetic levitation transportation module prefabricated panel transport vehicle. Background Art

[0002] Maglev trains are trains that are propelled by magnetic levitation. Due to the low friction, they can reach a speed of 600 kilometers per hour. The existing maglev railways are constructed with prefabricated panels. Maglev railway tunnels are straight tunnels with narrow space. In order to facilitate the rapid transportation of prefabricated panels, prefabricated panel transport vehicles are usually set up in the railway tunnels.

[0003] The existing prefabricated panel transport vehicle includes a traveling mechanism and a lifting mechanism. The lifting mechanism is arranged on the traveling mechanism. The traveling mechanism drives the lifting mechanism to move to the lifting position of the prefabricated panel or the installation position of the prefabricated panel. The lifting mechanism lifts or places the prefabricated panel so that the prefabricated panel can be quickly installed in the railway tunnel.

[0004] The traveling mechanism and the lifting mechanism in the above scheme usually operate independently, and it is difficult for the traveling mechanism and the lifting mechanism to form a mutual restriction. For example, when the traveling mechanism moves forward, the lifting mechanism may drop the precast panels, and the precast panels are also prone to fall due to unhooking, which results in poor safety in the lifting process of the precast panels. Summary of the invention

[0005] In order to improve the safety of transporting prefabricated panels by transport vehicles, the present application provides a magnetic levitation transportation module prefabricated panel transport vehicle.

[0006] The present application provides a magnetic levitation transportation module prefabricated panel transport vehicle, which adopts the following technical solution:

[0007] A magnetic levitation transportation module prefabricated panel transport vehicle, comprising:

[0008] A frame, rotatably connected to wheels;

[0009] A lifting frame is slidably arranged on the vehicle frame in a vertical direction;

[0010] A lifting assembly is arranged on the lifting frame and is used to lift the prefabricated panels. After sliding down the lifting frame, the lifting assembly is in a state of lifting or lowering the prefabricated panels. After sliding up the lifting frame, the lifting assembly is in a state of lifting the prefabricated panels.

[0011] The brake assembly includes a brake disc, a brake unit and a pulling wire rope. The brake disc is connected to the vehicle frame. The brake unit is arranged on the brake disc and is used to apply braking force to the wheel. One end of the pulling wire rope is connected to the brake unit, and the other end is connected to the hoisting frame. When the hoisting frame slides down, the hoisting frame drives the pulling wire rope to make the brake unit stop the wheel. When the hoisting frame slides up, the hoisting frame drives the pulling wire rope to make the brake unit release the braking force on the wheel.

[0012] The locking assembly comprises a locking oil box and a locking oil cylinder. The locking oil box is connected to the brake part, and the locking oil cylinder is connected to the lifting frame. A fluid medium flows between the locking oil box and the rod chamber of the locking oil cylinder. The rodless chamber of the locking oil cylinder is connected to the atmosphere. A locking spring is arranged in the rodless chamber of the locking oil cylinder. The locking spring is used to drive the locking oil cylinder to extend to fix the lifting state of the lifting assembly. When the brake part stops the parking wheel, the locking oil box is compressed to cause the locking oil cylinder to contract to release the locking cylinder from fixing the lifting state of the lifting assembly.

[0013] The supporting assembly includes a supporting plate and a supporting part. The supporting plate is rotatably connected to the lifting frame, and the supporting part is connected to the supporting plate. When the lifting frame slides up, the supporting part is used to make the supporting plate swing so that the end of the supporting plate is supported on the bottom end of the prefabricated board. When the lifting frame slides down, the supporting part is used to make the supporting plate swing in the opposite direction to release the support of the end of the supporting plate for the prefabricated board.

[0014] By adopting the above technical solution, when the transport vehicle lifts or lowers the prefabricated panel, the lifting frame is lowered to make the lifting assembly in a position where the prefabricated panel can be lifted or lowered, and the lifting frame drives the pulling wire rope to make the brake part stop the parking wheel, so that it is difficult for the frame to move by relying on the wheels when the prefabricated panel is lifted or lowered, thereby ensuring the safety of the prefabricated panel when it is lifted or lowered, and when the brake part stops the parking wheel, the locking oil box can drive the locking cylinder to contract to release the locking cylinder from fixing the lifting state of the lifting assembly, so that the lifting assembly can perform the lifting or lowering action.

[0015] When the transport vehicle is lifting the prefabricated panels, the lifting frame slides up to put the lifting assembly in a state of lifting the prefabricated panels, and the lifting frame drives and pulls the wire rope to make the brake part release the braking force on the wheels, so that the frame can automatically restore its walking ability when the prefabricated panels are lifted, and after the brake part releases the braking force on the wheels, the pressure on the locking oil box is released, and the locking cylinder can fix the lifting state of the lifting assembly under the drive of the locking spring, making it difficult for the lifting assembly to be lowered when lifting the prefabricated panels, thereby ensuring the safety of the prefabricated panel lifting process.

[0016] When sliding on the lifting frame to lift the prefabricated panel, the supporting part can drive the end of the supporting plate to support on the bottom end of the prefabricated panel to provide a stable supporting force for the prefabricated panel. On the one hand, it reduces the load of the lifting component, and on the other hand, the supporting plate can prevent the prefabricated panel from being unhooked and falling during the lifting process, thereby improving the safety of the prefabricated panel lifting process.

[0017] With the cooperation of the brake assembly, the locking assembly and the supporting assembly, mutual restrictions are formed between the movement of the frame and the lifting of the lifting assembly, making it difficult for the prefabricated panels to fall during the lifting process, thereby improving the safety of transporting prefabricated panels by the transport vehicle.

[0018] Optionally, the wheel is rotatably connected to an axle, the axle is connected to the frame, a brake groove is opened on the wheel, the brake disc is connected to the axle and is located in the brake groove, the brake part includes a brake rod, a brake plate and a brake wire rope, at least one group of brake rods is provided, each group of brake rods has two brake rods, one end of each group of two brake rods is slidably connected to the side wall of the brake disc, at least one brake plate is provided, and it corresponds to at least one group of brake rods, and one end of each group of two brake rods away from the brake disc is hinged to the corresponding brake plate The two brake rods of each group are arranged at an angle, at least one brake wire rope is arranged, and it corresponds to the brake rod of at least one group, the two ends of the brake wire rope are respectively connected to the ends of the two brake rods of the corresponding group close to the brake disc, the middle parts of all the brake wire ropes are connected to the ends of the pulling wire ropes away from the lifting frame, the pulling wire ropes are laid on the fixed pulley connected to the frame, when the lifting frame slides down, the pulling wire rope causes the brake wire rope to drive the two brake rods to reduce the angle, so that the brake plate is pressed against the groove wall of the brake groove.

[0019] By adopting the above technical solution, when the lifting frame slides down to lift or lower the prefabricated panel, the lifting frame can drive the pulling wire rope to move under the reversing action of the fixed pulley, and the pulling wire rope drives the middle part of the three brake wire ropes to move, so that the brake wire rope can drive the two brake rods to reduce the angle, so that the two brake rods can push the brake plate to press against the groove wall of the brake groove, so that during the lifting or lowering of the prefabricated panel, the frame is not easy to move, thereby improving the safety of lifting or lowering the prefabricated panel.

[0020] Optionally, the brake part also includes a brake spring, at least one brake spring is provided and corresponds one-to-one with at least one group of brake rods, the brake spring is arranged between two brake rods of the corresponding group, and the brake spring is used to drive the angle between the two brake rods to increase.

[0021] By adopting the above technical solution, after sliding on the lifting frame, the pulling force of the pulling wire rope on the brake wire rope is released. Under the elastic force of the brake spring, the angle between the two brake rods can be increased, so that the brake plate can be moved away from the groove wall of the brake groove, so that the wheel can automatically restore its rotation ability.

[0022] Optionally, at least one locking oil box is provided and corresponds one to one with the brake plate. The locking oil box is connected to one side of the brake plate close to the brake groove wall. When the brake plate applies braking force to the wheel, the locking oil box can be squeezed.

[0023] By adopting the above technical solution, when the brake pedal stops the wheel, the brake pedal can push the locking oil box against the groove wall of the brake groove. On the one hand, the friction between the brake pedal and the groove wall of the brake groove is increased by the locking oil box, thereby improving the braking performance of the brake pedal. On the other hand, the brake pedal can squeeze the locking oil box, so that the locking oil box can drive the locking cylinder to contract when the wheel is braked.

[0024] Optionally, the supporting part includes a supporting gear and a supporting rack, the supporting gear is rotatably connected to the lifting frame and is connected to the supporting plate, the supporting rack is meshed with the supporting gear and is connected to the frame, when the lifting frame slides up, the supporting rack drives the supporting gear so that the end of the supporting plate is supported on the bottom end of the prefabricated plate, when the lifting frame slides down, the supporting rack drives the supporting gear so that the supporting plate releases its support for the prefabricated plate.

[0025] By adopting the above technical solution, when the lifting frame slides up, the lifting frame drives the supporting gear to move upward relative to the supporting rack. Since the supporting rack is fixedly connected to the frame, the supporting rack can drive the supporting gear to rotate so that the end of the supporting plate can be supported on the bottom end of the prefabricated plate, thereby improving the safety of the prefabricated plate during the lifting process.

[0026] Optionally, the lifting assembly includes a lifting sprocket, a lifting chain, a hook, a transmission roller, a transmission sprocket and a lifting motor. The lifting sprockets are symmetrically arranged in at least two groups, and the number of lifting sprockets in each group is two. The two lifting sprockets in each group are rotatably arranged on the lifting frame. At least two lifting chains are arranged and correspond one-to-one with the at least two groups of lifting sprockets. The lifting chains are wound around the two lifting sprockets of the corresponding group. At least two groups of hooks are symmetrically arranged and correspond one-to-one with the at least two lifting chains. The number of hooks in each group is at least one. The hooks are hinged to the lifting chains and are used to hook the prefabricated panels.

[0027] There are two symmetrical transmission rollers, each of which is rotatably connected to the lifting frame. There are two groups of symmetrical transmission sprockets, which correspond to the transmission rollers one by one. Each group of transmission sprockets has at least one transmission sprocket, which is connected to the corresponding transmission roller. The transmission sprocket corresponds to the lifting chain one by one, and the transmission sprocket is meshed on the lifting chain. There are two lifting motors, which correspond to the transmission rollers one by one. The lifting motor is installed on the lifting frame. The output shaft of the lifting motor is connected to a connecting shaft, and the connecting shaft is connected to the transmission roller.

[0028] By adopting the above technical solution, when lifting the prefabricated board, the lifting motor is started, the lifting motor drives the transmission roller to rotate through the connecting shaft, the transmission roller drives the transmission sprocket to rotate, the transmission sprocket drives the lifting chain to rotate, the lifting chain drives the hook to move, and the hook is hooked on the prefabricated board during the movement to lift the prefabricated board, thereby making it easy to lift the prefabricated board.

[0029] Optionally, a locking hole is provided on the connecting shaft, two locking cylinders are provided and correspond one to one with the connecting shafts, and the movable end of the locking cylinder is used to be inserted into the locking hole under the drive of the locking spring to keep the transmission roller in a stationary state.

[0030] By adopting the above technical solution, after sliding on the lifting frame, the pressure on the locking oil box is released, and under the elastic force of the locking spring, the movable end of the locking cylinder can be inserted into the locking hole to make it difficult for the connecting shaft to rotate, thereby making it difficult for the prefabricated panel to be lowered during the lifting process.

[0031] Optionally, the hook includes a hook body and a closing rod, the hook body is hinged to the lifting chain, the closing rod is hinged to the hook body, the closing rod is connected to a swing rod, and a torsion spring is provided at the hinge between the closing rod and the hook body, the torsion spring is used to drive the closing rod to hook on the prefabricated board, when the closing rod is hooked on the prefabricated board, the prefabricated board drives the swing rod to swing so that the closing rod is pressed against the hook body.

[0032] By adopting the above technical solution, after the hook is hooked to the prefabricated board, the prefabricated board can push the swing arm to swing by its own gravity, and the swing arm drives the closing rod to swing, so that the closing rod is pressed tightly against the hook body, so that the hook can close its own opening after hooking to the prefabricated board by relying on the dead weight of the prefabricated board, thereby making it difficult for the prefabricated board to become unhooked.

[0033] Optionally, the hook body is provided with a button at the abutment position of the closing rod, the button is electrically connected to an indicator light, the indicator light is connected to the hook body, and when the button is squeezed, the indicator light is lit.

[0034] By adopting the above technical solution, when the prefabricated panel drives the swing arm to swing, the closing rod can be squeezed on the button to light up the indicator light, so that the closing condition of the hook opening by the closing rod can be intuitively judged according to the lighting condition of the indicator light.

[0035] Optionally, the number of hooks in each group is at least three.

[0036] By adopting the above technical solution and increasing the number of hooks, the lifting chain can continuously lift more than three prefabricated panels during rotation, thereby significantly increasing the efficiency of the transport vehicle in transporting the prefabricated panels.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. By setting the brake assembly, the locking assembly and the supporting assembly, the movement of the frame and the lifting of the lifting assembly are mutually restricted, and the prefabricated panels are not likely to fall during the lifting process, thereby improving the safety of the transport vehicle in transporting the prefabricated panels;

[0051] The following is combined with Figure 1-8 This application is described in further detail.

[0052] The present application discloses a magnetic levitation transportation module prefabricated panel transport vehicle. Figure 1 A magnetic levitation transportation module prefabricated panel transport vehicle includes a frame 1, a lifting frame 2, a lifting component 3, a brake component 4, a locking component 5 and a supporting component 6.

[0053] The frame 1 is rotatably connected to four wheels 11, and the four wheels 11 are symmetrically arranged on both sides of the moving direction of the frame 1. The lifting frame 2 is slidably arranged on the frame 1 along the vertical direction.

[0054] The lifting assembly 3 is arranged on the lifting frame 2 and is used for lifting the prefabricated panels. After the lifting frame 2 slides down, the lifting assembly 3 is in a state of lifting or lowering the prefabricated panels. After the lifting frame 2 slides up, the lifting assembly 3 is in a state of lifting the prefabricated panels.

[0055] Reference Figure 2 and Figure 3 The brake assembly 4 is provided with four groups, and corresponds to the wheels 11 one by one. The brake assembly 4 includes a brake disc 41, a brake part 42 and a pulling wire rope 43. The brake disc 41 is connected to the frame 1. The brake part 42 is arranged on the brake disc 41 and is used to apply braking force to the wheel 11. One end of the pulling wire rope 43 is connected to the brake part 42, and the other end is fixedly connected to the hoisting frame 2. When the hoisting frame 2 slides down, the hoisting frame 2 drives the pulling wire rope 43 to make the brake part 42 brake the wheel 11. When the hoisting frame 2 slides up, the hoisting frame 2 drives the pulling wire rope 43 to make the brake part 42 release the braking force on the wheel 11. When the hoisting assembly 3 is in motion, it can limit the movement of the frame 1 through the brake assembly 4.

[0056] Reference Figure 1 , Figure 3 and Figure 4 The locking assembly 5 includes a locking oil box 51 and a locking oil cylinder 52. The locking oil box 51 is provided with four groups, and corresponds to the brake part 42 one by one. Each group of locking oil boxes 51 is connected to the corresponding brake part 42. The locking oil cylinder 52 is fixedly connected to the lifting frame 2. Fluid medium flows through the pipeline between the rod chambers of all the locking oil boxes 51 and the locking oil cylinder 52. The rodless chamber of the locking oil cylinder 52 is provided with an air hole 521. The air hole 521 allows the rodless chamber of the locking oil cylinder 52 to be in contact with the rodless chamber of the locking oil cylinder 52. The locking oil box 51 is connected to the atmosphere, and a locking spring 53 is arranged in the rodless cavity of the locking oil cylinder 52. One end of the locking spring 53 is fixedly connected to the fixed end of the locking oil cylinder 52, and the other end is fixedly connected to the movable end of the locking oil cylinder 52. The locking spring 53 is used to drive the locking oil cylinder 52 to extend to fix the lifting state of the lifting assembly 3. When the brake part 42 stops the parking wheel 11, the locking oil box 51 is compressed to make the locking oil cylinder 52 contract to release the locking oil cylinder 52 from fixing the lifting state of the lifting assembly 3. When the frame 1 moves, the locking assembly 5 can limit the movement of the lifting assembly 3. In the present application, the fluid medium is hydraulic oil.

[0057] Reference Figure 1 and Figure 5 There are four supporting components 6, which are symmetrically arranged on the hoisting frame 2. The supporting components 6 include a supporting plate 61 and a supporting portion 62. The supporting plate 61 is rotatably connected to the hoisting frame 2, and the supporting portion 62 is connected to the supporting plate 61. When the hoisting frame 2 slides up, the supporting portion 62 is used to swing the supporting plate 61 so that the end of the supporting plate 61 is supported on the bottom end of the prefabricated board. When the hoisting frame 2 slides down, the supporting portion 62 is used to swing the supporting plate 61 in the opposite direction to release the support of the end of the supporting plate 61 on the prefabricated board. The supporting components 6 play a role in preventing the prefabricated board from falling.

[0058] During use, when the transport vehicle lifts or lowers the precast panel, the lifting frame 2 is lowered to make the lifting assembly 3 in a position where the precast panel can be lifted or lowered, and the lifting frame 2 drives the pulling wire rope 43 to make the brake part 42 stop the parking wheel 11, so that when the precast panel is lifted or lowered, the frame 1 is difficult to move by relying on the wheel 11, thereby ensuring the safety of the precast panel when it is lifted or lowered, and when the brake part 42 stops the parking wheel 11, the locking oil box 51 can drive the locking cylinder 52 to contract, so as to release the locking cylinder 52 from fixing the lifting state of the lifting assembly 3, so that the lifting assembly 3 can be lifted or lowered.

[0059] When the transport vehicle is lifting the prefabricated panels, the lifting frame 2 slides up to put the lifting assembly 3 in a state of lifting the prefabricated panels, and the lifting frame 2 drives the pulling wire rope 43 to make the brake part 42 release the braking force on the wheel 11, so that the frame 1 can automatically restore the walking ability when the prefabricated panels are lifted, and after the brake part 42 releases the braking force on the wheel 11, the pressure on the locking oil box 51 is released, and the locking cylinder 52 can fix the lifting state of the lifting assembly 3 under the drive of the locking spring 53, so that the lifting assembly 3 is difficult to be lowered when lifting the prefabricated panels, thereby ensuring the safety of the prefabricated panel lifting process.

[0060] When sliding on the lifting frame 2 to lift the precast panel, the supporting portion 62 can drive the end of the supporting plate 61 to support the bottom end of the precast panel to provide a stable supporting force for the precast panel. On the one hand, it reduces the load of the lifting component 3. On the other hand, the supporting plate 61 can prevent the precast panel from being unhooked and falling during the lifting process, thereby improving the safety of the precast panel lifting process.

[0061] With the cooperation of the brake assembly 4, the locking assembly 5 and the supporting assembly 6, mutual restrictions are formed between the movement of the frame 1 and the lifting of the lifting assembly 3, and the prefabricated panels are not prone to falling accidents during the lifting process, thereby improving the safety of transporting prefabricated panels by the transport vehicle.

[0062] In particular, refer to Figure 1 A plurality of lifting cylinders 21 are arranged between the lifting frame 2 and the frame 1 . The lifting cylinders 21 are fixedly connected to the frame 1 . The movable ends of the lifting cylinders 21 are fixedly connected to the lifting frame 2 . The lifting cylinders 21 can drive the lifting frame 2 to slide in the vertical direction relative to the frame 1 .

[0063] Reference Figure 2 The wheel 11 is connected to a travel motor 113, which is fixed to the frame 1. The output shaft of the travel motor 113 is connected to the wheel 11 through a belt transmission. The travel motor 113 drives the wheel 11 to rotate, so as to drive the frame 1 to move in the railway tunnel.

[0064] Specifically, refer to Figure 6 The brake part 42 includes a brake rod 421 , a brake plate 422 and a brake wire rope 423 .

[0065] Reference Figure 2 The wheel 11 is rotatably connected to an axle 111 , the axle 111 is fixedly connected to the frame 1 , a brake groove 112 is provided on one side of the wheel 11 close to the frame 1 , and the brake disc 41 is fixedly connected to the axle 111 and is located in the brake groove 112 .

[0066] Reference Figure 6There are three groups of brake rods 421, which are evenly arranged around the brake disc 41. Each group of brake rods 421 has two brake rods, and one end of each group of two brake rods 421 is slidably connected to the side wall of the brake disc 41. There are three brake plates 422, which correspond to the three groups of brake rods 421. One end of each group of two brake rods 421 away from the brake disc 41 is hinged on the corresponding brake plate 422, and the two brake rods 421 in each group are arranged at an angle.

[0067] Reference Figure 2 , Figure 3 and Figure 6 There are three brake wire ropes 423, which correspond to the three groups of brake rods 421 one by one. The two ends of the brake wire rope 423 are respectively fixedly connected to one end of the two brake rods 421 of the corresponding group close to the brake disc 41. The middle part of the brake wire rope 423 is slidably passed through the brake disc 41 and the axle 111. The middle parts of the three brake wire ropes 423 are all fixedly connected to the end of the pulling wire rope 43 away from the lifting frame 2. The pulling wire rope 43 is slidably passed through the axle 111. The pulling wire rope 43 is laid on the fixed pulley 431 fixedly connected to the frame 1. When the lifting frame 2 slides down, the pulling wire rope 43 causes the brake wire rope 423 to drive the two brake rods 421 to reduce the angle, so that the brake plate 422 is pressed against the groove wall of the brake groove 112.

[0068] When the lifting frame 2 slides down to lift or lower the precast panel, the lifting frame 2 can drive the pulling wire rope 43 to move under the reversing action of the fixed pulley 431, and the pulling wire rope 43 drives the middle part of the three brake wire ropes 423 to move, so that the brake wire rope 423 can drive the two brake rods 421 to reduce the angle, so that the two brake rods 421 can push the brake plate 422 to press against the groove wall of the brake groove 112, so that during the lifting or lowering of the precast panel, the frame 1 is not easy to move, thereby improving the safety of lifting or lowering the precast panel.

[0069] Further, refer to Figure 6 The brake part 42 also includes a brake spring 424. Three brake springs 424 are provided and correspond one to one with the three groups of brake rods 421. The brake spring 424 is fixed between two brake rods 421 of a corresponding group. The brake spring 424 is used to drive the angle between the two brake rods 421 to increase.

[0070] After the lifting frame 2 slides up, the pulling force of the pulling wire rope 43 on the brake wire rope 423 is released. Under the elastic force of the brake spring 424, the angle between the two brake rods 421 can be increased, so that the brake plate 422 can move away from the groove wall of the brake groove 112, so that the wheel 11 can automatically restore its rotation ability.

[0071] Furthermore, refer to Figure 6There are three locking oil boxes 51 in each group, and they correspond one to one with the three brake plates 422 of the corresponding brake part 42. The locking oil box 51 is fixedly connected to one side of the brake plate 422 close to the wall of the brake groove 112. When the brake plate 422 applies braking force to the wheel 11, the locking oil box 51 can be squeezed.

[0072] When the brake plate 422 brakes the wheel 11, the brake plate 422 can push the locking oil box 51 to press against the wall of the brake groove 112. On the one hand, the locking oil box 51 increases the friction between the brake plate 422 and the wall of the brake groove 112, thereby improving the braking performance of the brake plate 422. On the other hand, the brake plate 422 can squeeze the locking oil box 51, so that the locking oil box 51 can drive the locking cylinder 52 to contract when the wheel 11 is braked.

[0073] Specifically, refer to Figure 5 The supporting part 62 includes a supporting gear 621 and a supporting rack 622. The supporting gear 621 is rotatably connected to the lifting frame 2 and is fixedly connected to the supporting plate 61. The supporting rack 622 is meshed with the supporting gear 621 and is fixedly connected to the frame 1. The supporting rack 622 is slidably connected to the lifting frame 2. When the lifting frame 2 slides up, the supporting rack 622 drives the supporting gear 621 to support the end of the supporting plate 61 on the bottom end of the prefabricated plate. When the lifting frame 2 slides down, the supporting rack 622 drives the supporting gear 621 to release the supporting plate 61 from supporting the prefabricated plate.

[0074] When the lifting frame 2 slides up, the lifting frame 2 drives the supporting gear 621 to move upward relative to the supporting rack 622. Since the supporting rack 622 is fixedly connected to the frame 1, the supporting rack 622 can drive the supporting gear 621 to rotate, so that the end of the supporting plate 61 can be supported on the bottom end of the prefabricated plate, thereby improving the safety of the prefabricated plate during the lifting process.

[0075] Specifically, refer to Figure 4 and Figure 7 The lifting assembly 3 includes a lifting sprocket 31, a lifting chain 32, a hook 33, a transmission roller 34, a transmission sprocket 35 and a lifting motor 36.

[0076] Reference Figure 7 There are four groups of lifting sprockets 31 symmetrically arranged, each group of lifting sprockets 31 has two lifting sprockets, each group of two lifting sprockets 31 is rotatably arranged on the lifting frame 2, and the two lifting sprockets 31 are arranged in the vertical direction. There are four lifting chains 32, which correspond to the four groups of lifting sprockets 31 one by one, and the lifting chains 32 are wound around the two lifting sprockets 31 of the corresponding group. There are four groups of hooks 33 symmetrically arranged, which correspond to the four lifting chains 32 one by one, and each group of hooks 33 has at least one hook, which is hinged on the lifting chain 32 and is used to hook the precast panel.

[0077] Reference Figure 4 , two transmission rollers 34 are symmetrically arranged, and each transmission roller 34 is rotatably connected to the lifting frame 2. Two groups of transmission sprockets 35 are symmetrically arranged, and correspond to the transmission rollers 34 one by one. The number of each group of transmission sprockets 35 is two, and they are all fixedly connected to the corresponding transmission rollers 34. The transmission sprockets 35 correspond to the lifting chains 32 one by one. The transmission sprockets 35 are meshed on the lifting chains 32 and are located outside the area surrounded by the lifting chains 32. Two lifting motors 36 are arranged, and correspond to the transmission rollers 34 one by one. The lifting motors 36 are fixedly connected to the lifting frame 2. The output shaft of the lifting motor 36 is fixedly connected to the connecting shaft 361, and the connecting shaft 361 is fixedly connected to the transmission rollers 34.

[0078] When lifting the prefabricated board, the lifting motor 36 is started, and the lifting motor 36 drives the transmission roller 34 to rotate through the connecting shaft 361, and the transmission roller 34 drives the transmission sprocket 35 to rotate, and the transmission sprocket 35 drives the lifting chain 32 to rotate, and the lifting chain 32 drives the hook 33 to move. The hook 33 is hooked on the prefabricated board during the movement to lift the prefabricated board, thereby making it easy to lift the prefabricated board.

[0079] Further, refer to Figure 4 A locking hole 362 is provided on the connecting shaft 361, and two locking cylinders 52 are provided, which correspond one to one with the connecting shaft 361. The movable end of the locking cylinder 52 is used to be inserted into the locking hole 362 under the drive of the locking spring 53 to keep the driving roller 34 in a stationary state.

[0080] In particular, refer to Figure 1 , Figure 3 and Figure 4 The two locking cylinders 52 are respectively located on both sides of the frame 1 in the direction of travel, and fluid medium flows through pipelines between all the locking oil boxes 51 on each side of the frame 1 in the direction of travel and the rod chambers of the locking cylinders 52 on the corresponding side.

[0081] After sliding up the lifting frame 2, the pressure on the locking oil box 51 is released, and under the elastic force of the locking spring 53, the movable end of the locking cylinder 52 can be inserted into the locking hole 362, so that the connecting shaft 361 is difficult to rotate, thereby making it difficult for the precast panel to be lowered during the lifting process.

[0082] Reference Figure 7 and Figure 8In order to prevent the prefabricated board from being unhooked, the hook 33 includes a hook body 331 and a closing rod 332. The hook body 331 is hinged to the lifting chain 32, and the closing rod 332 is hinged to the hook body 331. The closing rod 332 is fixedly connected with a swing rod 333. The closing rod 332 and the swing rod 333 are arranged at an acute angle. A torsion spring 334 is arranged at the hinge between the closing rod 332 and the hook body 331. The two ends of the torsion spring 334 are respectively fixedly connected to the closing rod 332 and the hook body 331. The torsion spring 334 is used to drive the closing rod 332 to hook on the prefabricated board. When the closing rod 332 is hooked on the prefabricated board, the prefabricated board drives the swing rod 333 to swing so that the closing rod 332 is pressed against the hook body 331.

[0083] After the hook 33 is hooked to the prefabricated board, the prefabricated board can push the swing rod 333 to swing by its own gravity, and the swing rod 333 drives the closing rod 332 to swing, so that the closing rod 332 is pressed tightly against the hook body 331. Therefore, by relying on the dead weight of the prefabricated board, the hook 33 can close its own opening after being hooked to the prefabricated board, thereby making it difficult for the prefabricated board to be unhooked.

[0084] Further, refer to Figure 8 A button 335 is fixedly provided on the hook body 331 at the abutting position of the closing rod 332. The button 335 is electrically connected to an indicator light 336. The indicator light 336 is fixedly connected to the hook body 331. When the button 335 is squeezed, the indicator light 336 lights up.

[0085] When the prefabricated plate drives the swing arm 333 to swing, the closing rod 332 can be pressed against the button 335 to light up the indicator light 336. Thus, according to the lighting of the indicator light 336, it is possible to intuitively judge whether the closing rod 332 is closing the opening of the hook 33.

[0086] Reference Figure 7 In order to enable the transport vehicle to transport multiple prefabricated panels at a time, the number of hooks 33 in each group is at least three.

[0087] By increasing the number of hooks 33, the lifting chain 32 can continuously lift more than three prefabricated panels during the rotation process, so that the efficiency of transporting the prefabricated panels by the transport vehicle is significantly increased.

[0088] The implementation principle of a magnetic levitation transportation module prefabricated panel transport vehicle in an embodiment of the present application is as follows: when in use, the lifting cylinder 21 drives the lifting frame 2 to slide vertically, and when the lifting frame 2 slides down to lift or lower the prefabricated panel, the brake assembly 4 brakes the parking wheel 11 to enable the lifting assembly 3 to safely lift or lower the prefabricated panel, and when the lifting frame 2 slides up to lift the prefabricated panel, the brake assembly 4 automatically releases the braking force on the wheel 11, and the locking assembly 5 locks the lifting state of the lifting assembly 3 to make it difficult for the lifting assembly 3 to be lowered during the lifting process, and the supporting assembly 6 provides support force to the bottom end of the prefabricated panel to prevent the prefabricated panel from falling during the lifting process, thereby improving the safety of the transport vehicle in transporting the prefabricated panels.

[0089] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
