Description

Technical Field

[0001] The present invention relates to the technical field of ceiling transportation devices, and particularly to a transportation device for ceiling semi-finished products. Background Art

[0002] With the continuous development of the construction industry, the application of prefabricated building components, especially ceiling semi-finished products, in construction is becoming increasingly widespread. Ceiling semi-finished products are usually large in size, complex in shape, and heavy in weight, and are prone to damage during handling and transportation, which affects the construction progress and project quality. Traditional transportation of ceiling semi-finished products mostly relies on manual handling or simple mechanical equipment, with low efficiency and potential safety hazards.

[0003] After retrieval, it is found that the prior art publication number is CN115771555A, which discloses a building board transport vehicle. The building board transport vehicle includes: a chassis; and a discharging assembly provided on one side of the chassis for discharging building boards. The discharging assembly includes: a first rotating rod rotatably connected to the chassis; a second rotating rod, one side of which is rotatably connected to the first rotating rod, and the other side is rotatably connected to a material receiving box, and the material receiving box is rotatably connected to the chassis; a cross bar fixedly connected to the connection part of the first rotating rod and the second rotating rod; and a telescopic member rotatably connected to the cross bar. This solution can avoid the falling of building boards by setting an auxiliary assembly, and can further improve the use range of the transport vehicle by setting a moving assembly. By combining the discharging assembly, the auxiliary assembly and the moving assembly, the convenience of discharging building boards is greatly improved.

[0004] Therefore, based on the above retrieval and in combination with the existing technology, at present, the transportation of ceiling semi-finished product boards mostly uses manual handling or ordinary flat carts for transfer. The existing transportation methods have the following problems: First, there is a lack of an effective limiting structure, and the boards are prone to slipping, tilting or even falling during transportation, with relatively large safety hazards; Second, the stacking process mainly relies on manual operation, which not only has a large labor intensity and low efficiency, but also easily causes misalignment of the stacked boards, affecting subsequent construction use; Third, the structure of the existing transportation device is relatively fixed, lacking detachable or adjustable components, with poor versatility and difficulty in adapting to ceiling semi-finished product boards of different sizes or types. For this reason, this application proposes a transportation device for ceiling semi-finished products. Summary of the Invention

[0005] The purpose of the present invention is to provide a transportation device for ceiling semi-finished products to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A transportation device for semi-finished ceiling products, including a transportation cart, on the upper end of which a baffle is fixedly installed. The baffle forms a loading space for accommodating the semi-finished ceiling board. By applying an external force to the transportation cart, it moves along the ground or track, thereby transporting the semi-finished ceiling board to the target station. Four corners of the transportation cart are respectively fixedly installed with outer protection cylinders, and a screw rod is rotatably installed in each outer protection cylinder. The screw gap of the screw rod forms a guiding channel for accommodating the semi-finished ceiling board. When the screw rod rotates, the semi-finished ceiling board placed in the screw gap moves downward along the spiral track until it abuts against the bottom of the baffle, realizing automatic stacking. Two bottom plates are installed on the upper end of the transportation cart. The bottom plate on the right is slidably connected to the baffle, and the bottom end of the bottom plate on the left side of the transportation cart is fixedly connected with a pneumatic cylinder through a clamp.

[0007] As a further scheme of the present invention, a winding is rotatably installed at the inner end of the outer protection cylinder. The upper end of the winding is fixedly connected to the screw rod to achieve synchronous rotation. A limiting cylinder is also rotatably installed at the inner end of the outer protection cylinder. The upper end of the limiting cylinder is fixedly connected to the bottom end of the winding. An elastic clamping connection is realized between the limiting cylinder and the outer protection cylinder through a torsion spring coil. A driving rope is fixedly wound on the outer surface of the winding.

[0008] As a further scheme of the present invention, a driving rod penetrates through the inner end of the pneumatic cylinder. The end of the driving rod is fixedly connected with a movable plug through a bolt. The movable plug is located inside the pneumatic cylinder. A partition plate is fixedly installed at the inner end of the pneumatic cylinder. A movable tube penetrates through the outer surface of the partition plate, and the movable tube is connected to the movable plug through a traction wire. By setting a movable plug at the end of the driving rod and placing it inside the pneumatic cylinder, cooperating with the partition plate provided at the inner end of the pneumatic cylinder and the movable tube penetrating through the outer surface of the partition plate, and using the linkage structure between the movable plug and the movable tube through the traction wire, effective control of the gas flow or pressure transmission inside the pneumatic cylinder is achieved. The structure is compact, the response is sensitive, it is convenient to achieve precise driving and stable output, and the practicability and reliability of the device are improved.

[0009] As a further scheme of the present invention, two through holes are opened on the outer surface of the movable plug. Sealing covers are arranged on one side of the two through holes close to the movable tube, and a cooperating rod is fixedly installed on the outer surface of the sealing cover. The cooperating rod penetrates through the through hole, and the sealing cover and the movable plug are connected through a return spring. By opening through holes on the outer surface of the movable plug and setting a sealing cover on the side close to the movable tube, a cooperating rod fixedly installed on the outer surface of the sealing cover penetrates through the through hole, and the sealing cover and the movable plug are connected through a return spring. This structure can realize the axial movement of the cooperating rod under the action of an external force, thereby controlling the opening and closing of the through hole; when the external force is removed, the return spring pushes the sealing cover back to its original position to achieve automatic sealing.

[0010] As a further solution of the present invention, a gas guiding column is inserted through the inner end of the movable pipe. A flow guiding groove is formed on the outer surface of the gas guiding column, and the gas guiding column is connected to the movable pipe through a reset elastic sheet. A support plate is fixedly installed at the upper end of the transport cart. This structure can effectively guide the air flow and achieve the automatic reset function, ensuring the stability of gas flow and the reliable operation of the device. At the same time, the support plate fixedly installed at the upper end of the transport cart enhances the load-bearing capacity and stability of the overall structure, improving the safety and durability of the transport cart during use.

[0011] As a further solution of the present invention, two passive rings are rotatably installed at the upper end of the support plate. A gas guiding pipe is fixedly installed at the upper end of the support plate through a clamp. A passive plug is inserted through the inside of the gas guiding pipe. The passive plug is connected to the gas guiding pipe through an auxiliary spring. By rotatably installing passive rings at the upper end of the support plate and providing a gas guiding pipe fixed through a clamp, with a passive plug inserted through the inside of the gas guiding pipe and connected to it through an auxiliary spring, the passive plug can be driven to move under changes in air pressure or external forces, realizing the opening and closing control of the gas guiding path.

[0012] As a further solution of the present invention, an auxiliary rod is rotatably installed at one end of the passive plug close to the passive ring, and the end of the auxiliary rod is rotatably connected to the outer surface of the passive ring. A passive wheel is inserted through the inner end of the passive ring. A plurality of clamping plates are rotatably installed on the outer surface of the passive wheel through a rotating shaft. The clamping plates are arranged in a ring shape and are located inside the passive ring. A plurality of triangular teeth are fixedly installed at the inner end of the passive ring. The triangular teeth are arranged in a ring shape, and the end of the clamping plate is clamped between two adjacent triangular teeth.

[0013] As a further solution of the present invention, an extension plate is fixedly sleeved on the outer surface of the gas guiding pipe. A rectangular hole is formed on the outer surface of the extension plate. A passive block is inserted through the rectangular hole. An expansion rod is rotatably installed on the outer surface of the passive block through a rotating shaft. The telescopic end of the expansion rod is rotatably connected to the passive plug. Two locking rods are rotatably installed on the outer surface of the extension plate.

[0014] As a further solution of the present invention, two traction plates are rotatably installed on the outer surface of the passive block. The end of the traction plate is rotatably connected to the outer surface of the locking rod. By rotatably installing traction plates on the outer surface of the passive block and rotatably connecting the ends of the traction plates to the outer surface of the locking rod, a flexible linkage structure is formed.

[0015] As a further solution of the present invention, a plurality of locking blocks are fixedly installed on the outer surface of the passive wheel. The locking blocks are arranged in a ring shape. The locking blocks are clamped in the gaps between a plurality of locking blocks. This structure can effectively prevent the accidental sliding or rotation of the passive wheel, enhancing the stability and safety of the overall device and ensuring the reliable operation of the locking device.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By providing a detachable baffle at the upper end of the transport trolley, a loading space for accommodating the semi-finished ceiling board is formed, which can effectively prevent the board from slipping or tilting during transportation, and improve the stability and safety during transportation; 2. By matching the pitch of the screw rod with the thickness of the semi-finished ceiling board, it can ensure that only one board is allowed to pass through each time, effectively preventing the stacking misalignment caused by multiple boards falling simultaneously, and ensuring neat and orderly stacking.

Detailed implementation manner

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0020] Please refer to Figures 1 - 3 , a transport device for a semi-finished ceiling product, including a transport cart 1. The upper end of the transport cart 1 is fixedly installed with a baffle 2 through a detachable connecting member (such as a bolt). The baffle 2 forms a loading space for accommodating the semi-finished ceiling board. By applying an external force to the transport cart 1, it is moved along the ground or track, so as to transport the semi-finished ceiling board to the target station. Four corners of the transport cart 1 are respectively fixedly installed with outer protection cylinders 201. A screw rod 202 is rotatably installed in each outer protection cylinder 201. The screw gap of the screw rod 202 forms a guiding channel for accommodating the semi-finished ceiling board. When the screw rod 202 rotates, the semi-finished ceiling board placed in the screw gap moves downward along the spiral track until it abuts against the bottom of the baffle 2, realizing automatic stacking. Specifically, the pitch of the screw rod 202 matches the thickness of the semi-finished ceiling board, ensuring that only one board is allowed to pass through at a time and avoiding stacking misalignment; Two bottom plates 101 are installed at the upper end of the transport cart 1. The left bottom plate 101 is fixedly sleeved on the outer surfaces of the two outer protection cylinders 201 located on the left side of the transport cart 1. The right bottom plate 101 is slidably connected to the baffle 2 through a slide rail. The two outer protection cylinders 201 located on the right side of the transport cart 1 are fixedly connected to the right bottom plate 101. The bottom end of the left bottom plate 101 located on the left side of the transport cart 1 is fixedly connected with an air compression cylinder 301 through a clamp.

[0021] Such as Figure 3 , Figure 4As shown in the figure, a rectangular hole is formed on the outer surface of the baffle 2, and an auxiliary lifting plate 3 is inserted into the rectangular hole. The auxiliary lifting plate 3 is horizontally arranged between two adjacent outer protection cylinders 201. The right end of the auxiliary lifting plate 3 is rotatably installed with a lifting plate 31 through a rotating shaft. The lifting plate 31 is located inside the bearing baffle 2. A limiting block is fixedly installed at the bottom end of the lifting plate 31. The limiting block contacts the outer surface of the auxiliary lifting plate 3 to limit the lifting plate 31 to rotate only upward unidirectionally. When the stacked semi-finished ceiling plates move upward, their edges first contact the bottom end of the lifting plate 31 and push the lifting plate 31 to rotate upward. When the semi-finished ceiling plates completely pass through the lifting plate 31, the lifting plate 31 falls back under the action of gravity, and its edge area automatically lies below the semi-finished ceiling plates. By pressing the left end of the auxiliary lifting plate 3, the lifting plate 31 is driven to tilt upward to lift the semi-finished ceiling plates, facilitating manual extraction. Embodiment

[0022] Please refer to Figures 5 - 8 , a transportation device for semi-finished ceiling products. Based on Embodiment 1, a winding 203 is rotatably installed at the inner end of the outer protection cylinder 201. The upper end of the winding 203 is fixedly connected to the screw rod 202 to achieve synchronous rotation. A limiting cylinder 205 is also rotatably installed at the inner end of the outer protection cylinder 201. The upper end of the limiting cylinder 205 is fixedly connected to the bottom end of the winding 203. An elastic clamping connection is achieved between the limiting cylinder 205 and the outer protection cylinder 201 through a torsion spring coil 206. A driving rope 204 is fixedly wound on the outer surface of the winding 203; A driving rod 302 is inserted into the inner end of the air pressure cylinder 301. The end of the driving rod 302 is fixedly connected with a movable plug 303 through a bolt. The movable plug 303 is located inside the air pressure cylinder 301. A sealing rubber ring is sleeved on the outer surface of the movable plug 303 and contacts the inner wall of the air pressure cylinder 301 to increase airtightness. A pull rod 4 is rotatably installed on the outer surface of the baffle 2 through a rotating shaft. The bottom end of the pull rod 4 is clamped on the outer surface of the driving rod 302. When the pull rod 4 is pulled away from the baffle 2, the driving rod 302 moves toward the inside of the air pressure cylinder 301. If the pull rod 4 is pushed to rotate toward the baffle 2, its bottom end drives the driving rod 302 to move away from the air pressure cylinder 301.

[0023] An isolation plate is fixedly installed at the inner end of the air pressure cylinder 301. A movable tube 304 is inserted through the outer surface of the isolation plate. The movable tube 304 is connected to the movable plug 303 through a traction wire 305. Two through holes are formed on the outer surface of the movable plug 303. Sealing caps 306 are arranged on one side of the two through holes close to the movable tube 304. A matching rod is fixedly installed on the outer surface of the sealing cap 306. The matching rod is inserted into the through hole. The diameter of the matching rod is smaller than the aperture of the through hole. The sealing cap 306 is connected to the movable plug 303 through a return spring 307. When the movable plug 303 moves toward the movable tube 304, the sealing cap 306 closes the through holes on the outer surface of the movable plug 303; When the movable plug 303 moves away from the movable tube 304, the air pressure pushes open the sealing cover 306, allowing air to enter the chamber formed between the movable plug 303 and the movable tube 304, thereby achieving one-way airflow control and ensuring that the gas can only enter the chamber in one direction. At the same time, the opening and closing action of the sealing cover 306 effectively prevents the gas from flowing back.

[0024] like Figure 7 、 Figure 8 As shown, an air guide column 309 is provided at the inner end of the movable tube 304. A guide groove is provided on the outer surface of the air guide column 309. When the movable plug 303 moves toward the movable tube 304, the air guide column 309 moves under the action of air pressure. At this time, air flows along the guide groove to the right side of the movable tube 304. The air guide column 309 and the movable tube 304 are connected by a reset spring 308. After the air guide column 309 moves, it returns to its initial state under the elastic force of the reset spring 308. More specifically, a limit block is fixedly installed on the outer surface of the movable tube 304, and the limit block is located on the left side of the isolation plate, so that the movable tube 304 cannot move to the right when subjected to force. In the default state, the traction line 305 is in a straight state, the movable plug 303 moves toward the direction of the movable tube 304, and the traction line 305 is in a relaxed state.

[0025] like Figure 3 、 Figure 6 、 Figure 9 As shown, a support plate 102 is fixedly installed on the upper end of the transport cart 1, and two passive rings 413 are rotatably installed on the upper end of the support plate 102. An air duct 401 is fixedly installed on the upper end of the support plate 102 through a clamp. The air duct 401 is connected to the air cylinder 301, and a passive plug 402 is passed through the interior of the air duct 401. The passive plug 402 and the air duct 401 are connected by an auxiliary spring 403. Specifically, a sealing rubber ring is provided on the outer surface of the passive plug 402, and fits with the inner wall of the air duct 401 to increase air tightness. More specifically, an air vent is opened on the outer surface of the air duct 401. When the passive plug 402 is moved to the position of the air vent by air pressure, the air flows out along the gap between the passive plug 402 and the air vent.

[0026] like Figure 10 、 Figure 11 As shown, an auxiliary rod 414 is rotatably mounted on one end of the passive plug 402 close to the passive ring 413 via a rotating shaft, and the end of the auxiliary rod 414 is rotatably connected to the outer surface of the passive ring 413. A passive wheel 404 is passed through the inner end of the passive ring 413, and the end of the driving rope 204 is fixedly wound around the outer surface of the passive wheel 404. A plurality of clamping plates 411 are rotatably mounted on the outer surface of the passive wheel 404 via a rotating shaft. The clamping plates 411 are arranged in a ring shape and are located inside the passive ring 413. Specifically, the clamping plates 411 and the driven wheel 404 are connected by elastic pieces. A plurality of triangular teeth 412 are fixedly installed at the inner end of the passive ring 413. The triangular teeth 412 are arranged in a ring shape, and the end of the clamping plate 411 is stuck between two adjacent triangular teeth 412. When the passive ring 413 rotates forward, its triangular teeth 412 mesh with the clamping plate 411 to drive the driven wheel 404 to rotate synchronously. When the passive ring 413 rotates reversely, the ramp surface of the triangular teeth 412 contacts the end of the clamping plate 411, causing the clamping plate 411 to rotate towards the driven wheel 404. At this time, the passive ring 413 cannot drive the driven wheel 404 to rotate synchronously.

[0027] An extension plate 406 is fixedly sleeved on the outer surface of the air duct 401. A rectangular hole is formed in the outer surface of the extension plate 406. A passive block 408 is inserted through the rectangular hole. The passive block 408 can move freely in the rectangular hole. The outer surface of the passive block 408 is rotatably installed with a telescopic rod 407 through a rotating shaft. The telescopic end of the telescopic rod 407 is rotatably connected to the passive plug 402. By default, the telescopic rod 407 is in a fully extended state. Two locking rods 405 are rotatably installed on the outer surface of the extension plate 406 through rotating shafts. Two traction plates 409 are rotatably installed on the outer surface of the passive block 408. The end of the traction plate 409 is rotatably connected to the outer surface of the locking rod 405. By default, the traction plate 409 and the locking rod 405 are perpendicular to each other. When the passive block 408 moves towards the air duct 401, the traction plate 409 changes from a vertical state to an inclined state. Therefore, under the traction force of the traction plate 409, the locking rod 405 rotates upward; A plurality of locking blocks 410 are fixedly installed on the outer surface of the driven wheel 404. The locking blocks 410 are arranged in a ring shape. The locking blocks 410 are stuck in the gaps between the plurality of locking blocks 410. The end of the locking rod 405 is triangular. When the driven wheel 404 rotates forward, the locking block 410 contacts the inclined surface of the locking rod 405. After the locking block 410 rotates, it returns to the initial state under the traction force of the telescopic rod 407.

[0028] As Figure 2 、 Figure 12 shown, a driving gear 207 is fixedly sleeved on the upper end of the winding 203. The driving gear 207 is located inside the outer protection cylinder 201. The driving gear 207 and the driving gear 207 inside the opposite outer protection cylinder 201 are tensioned and sleeved by a toothed belt 103. The two bottom plates 101 above the transport trolley 1 are connected by two folding rods 104. Tensioning wheels 105 are rotatably installed at the center folding points of the two folding rods 104. The tensioning wheels 105 are inserted into the toothed belt 103. When the two bottom plates 101 approach each other, the folding action of the folding rods 104 causes the tensioning wheels 105 to approach synchronously, thereby tensioning and expanding the toothed belt 103, effectively preventing the transmission failure of the toothed belt 103 when the distance between the bottom plates 101 decreases; The tightness of the toothed belt 103 is automatically adjusted through mechanical linkage to ensure stable and reliable power transmission of the drive system under different working conditions, and at the same time, it is also possible to load semi-finished boards of different sizes.

[0029] The working principle of the present invention is as follows: When taking out the semi-finished board, the pull rod 4 is intermittently pulled, so that the bottom end of the pull rod 4 drives the drive rod 302 to move towards the inside of the air compression cylinder 301. At this time, the movable plug 303 squeezes the air into the inside of the movable tube 304, and starts to squeeze the air guide column 309 to move. Subsequently, the air comes into the inside of the air guide pipe 401 and pushes the passive plug 402. When the passive plug 402 moves, it drives the passive ring 413 to rotate through the auxiliary rod 414. When the pull rod 4 returns to its original position, the passive plug 402 returns to its initial state under the elastic force of the auxiliary spring 403, and then moves towards the direction close to the passive ring 413 during the pulling process of the pull rod 4. When the passive ring 413 rotates, its triangular teeth 412 mesh with the clamping plate 411, driving the passive wheel 404 to rotate synchronously, and winding the drive rope 204 around the outer surface of the passive wheel 404; During the process of the drive rope 204 being pulled, it drives the winding 203 to rotate. During the rotation of the winding 203, the torsion spring coil 206 is compressed. Subsequently, the screw rod 202 starts to rotate, causing the semi-finished board inside the baffle 2 to move upward. Subsequently, the worker can take out the semi-finished board; When placing the baffle 2 into the baffle 2, since the torsion spring coil 206 is in a compressed state, when pushing the pull rod 4 towards the baffle 2 at this time, the drive rod 302 moves away from the air compression cylinder 301. Subsequently, the movable plug 303 pulls the movable tube 304 to move through the traction wire 305. Since the chamber between the air compression cylinder 301 and the passive plug 402 is airtight, the passive plug 402 moves along with the movement of the movable tube 304. Since the telescopic rod 407 is in a fully extended state, when the passive plug 402 moves at this time, it pulls the passive block 408 to move through the telescopic rod 407. At this time, the passive block 408 moves towards the direction close to the air guide pipe 401, and the traction plate 409 changes from a vertical state to an inclined state. Therefore, the locking rod 405 rotates upward under the traction force of the traction plate 409. At this time, the passive wheel 404 rotates in the reverse direction under the traction force of the drive rope 204; The screw rod 202 also starts to rotate at this time and drives the semi-finished board to move downward. After the pressure on the pull rod 4 is ended, the screw rod 202 also stops rotating. By continuously repeating the above actions, the loading of the semi-finished board is realized.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
