Description

Technical Field

[0002] With the continuous development of the construction industry, prefabricated building components, especially semi-finished ceiling products, are increasingly used in construction. Semi-finished ceiling products are usually large in size, complex in shape, and heavy in weight. They are easily damaged during handling and transportation, affecting the construction progress and project quality. Traditional transportation of semi-finished ceiling products mostly relies on manual handling or simple mechanical equipment, which is inefficient and poses safety hazards.

[0003] After searching, it was found that the prior art publication number is CN115771555A, which discloses a building board transport vehicle, which includes: a base frame; and a discharging assembly arranged on one side of the base frame for discharging building boards; the discharging assembly includes: a first rotating rod rotatably connected to the base frame; 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 box, and the material box is rotatably connected to the base frame; a cross bar is fixedly connected at the connection between the first rotating rod and the second rotating rod; and a telescopic part rotatably connected to the cross bar. This scheme can prevent building boards from falling by setting an auxiliary assembly, and can further improve the scope of use 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 search and in combination with existing technologies, currently, the transportation of semi-finished ceiling panels mostly adopts manual handling or ordinary flatbed carts for transfer. The existing transportation methods have the following problems: First, there is a lack of effective limiting structure, and the panels are prone to slipping, tilting or even falling during transportation, posing a major safety hazard; second, the stacking process mainly relies on manual operation, which is not only labor-intensive and inefficient, but also easily causes the panels to be misplaced, affecting subsequent construction and use; third, the existing transportation device has a relatively fixed structure and lacks detachable or adjustable components. It has poor versatility and is difficult to adapt to different sizes or types of semi-finished ceiling panels. For this reason, this application proposes a transportation device for semi-finished ceiling panels. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1-Figure 3 , a transport device for semi-finished ceiling products, comprising a transport trolley 1, the upper end of which is fixedly mounted with a baffle 2 by a detachable connecting piece (such as a bolt), the baffle 2 forming a loading space for accommodating the semi-finished ceiling panels, and an external force is applied to the transport trolley 1 to make it move along the ground or track, thereby transporting the semi-finished ceiling panels to the target workstation, and outer casings 201 are fixedly mounted on the four corners of the transport trolley 1, and a spiral rod 202 is rotatably mounted in each outer casing 201, and the spiral gap of the spiral rod 202 constitutes a guide channel for accommodating the semi-finished ceiling panels, and the spiral rod 202 rotates to make the semi-finished ceiling panels placed in the spiral gap move downward along the spiral track until they abut against the bottom of the baffle 2, thereby realizing automatic stacking, specifically, the pitch of the spiral rod 202 matches the thickness of the semi-finished ceiling panels, ensuring that only one panel is allowed to pass through at a time, thereby avoiding stacking misalignment;

[0038] Two base plates 101 are installed at the upper end of the transport trolley 1. The base plate 101 on the left is fixedly sleeved on the outer surfaces of the two outer casings 201 located on the left side of the transport trolley 1. The base plate 101 on the right is slidably connected to the baffle 2 through a slide rail. The two outer casings 201 located on the right side of the transport trolley 1 are fixedly connected to the base plate 101 on the right side. The bottom end of the base plate 101 on the left side of the transport trolley 1 is fixedly connected to the air cylinder 301 through a clamp.

[0039] like Figure 3 、 Figure 4 As shown, a rectangular hole is provided on the outer surface of the baffle 2, and an auxiliary lifting plate 3 is passed through the rectangular hole. The auxiliary lifting plate 3 is horizontally arranged between two adjacent outer casings 201, and 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 on the inner side of the supporting baffle 2, and a limit block is fixedly installed on the bottom end of the lifting plate 31. The limit block contacts the outer surface of the auxiliary lifting plate 3, limiting the lifting plate 31 to only rotate in one direction upward. When the stacked semi-finished ceiling panels move upward, their edges first contact the bottom ends of the lifting plates 31 and push the lifting plates 31 to rotate upward. When the semi-finished ceiling panels completely pass through the lifting plates 31, the lifting plates 31 fall back under the action of gravity, and their edge areas are automatically located below the semi-finished ceiling panels. By pressing down the left end of the auxiliary lifting plate 3, the lifting plate 31 is driven to tilt upward, lifting the semi-finished ceiling panels for easy manual extraction.

[0040] Example 2: Please refer to Figure 5-Figure 8 A transport device for a semi-finished ceiling product is provided. Based on the first embodiment, a winding 203 is rotatably mounted on the inner end of an outer casing 201. The upper end of the winding 203 is fixedly connected to a spiral rod 202 to achieve synchronous rotation. A limiting cylinder 205 is also rotatably mounted on the inner end of the outer casing 201. The upper end of the limiting cylinder 205 is fixedly connected to the bottom end of the winding 203. The limiting cylinder 205 and the outer casing 201 are elastically connected by a torsion spring coil 206. A driving rope 204 is fixedly wound around the outer surface of the winding 203.

[0041] A driving rod 302 is passed through the inner end of the air cylinder 301, and the end of the driving rod 302 is fixedly connected to a movable plug 303 by bolts. The movable plug 303 is located inside the air cylinder 301, and the outer surface of the movable plug 303 is sleeved with a sealing rubber ring and contacts the inner wall of the air cylinder 301 to increase the air tightness. The outer surface of the baffle 2 is rotated by a rotating shaft and a pull rod 4 is installed. The bottom end of the pull rod 4 is clamped to 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 cylinder 301. If the pull rod 4 is pushed to rotate in the direction close to the baffle 2, its bottom end drives the driving rod 302 to move away from the air cylinder 301.

[0042] An isolation plate is fixedly installed at the inner end of the air cylinder 301. A movable tube 304 is passed through the outer surface of the isolation plate. The movable tube 304 is connected to the movable plug 303 by a traction line 305. Two through holes are provided on the outer surface of the movable plug 303. A sealing cover 306 is provided on the side of each through hole close to the movable tube 304. A matching rod is fixedly installed on the outer surface of the sealing cover 306. The matching rod is passed through the through hole. The diameter of the matching rod is smaller than the aperture of the through hole. The sealing cover 306 is connected to the movable plug 303 by a return spring 307. When the movable plug 303 moves toward the movable tube 304, the sealing cover 306 closes the through hole on the outer surface of the movable plug 303.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] like Figure 3 、 Figure 6 、 Figure 9As 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 guide tube 401 is fixedly installed on the upper end of the support plate 102 through a clamp. The air guide tube 401 is communicated with the air cylinder 301, and a passive plug 402 is passed through the interior of the air guide tube 401. The passive plug 402 and the air guide tube 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 guide tube 401 to increase air tightness. More specifically, an air vent is opened on the outer surface of the air guide tube 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.

[0047] 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.

[0048] Specifically, the clamping plate 411 and the passive wheel 404 are connected by a spring clip, and a plurality of triangular teeth 412 are fixedly installed on 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 clamped between two adjacent triangular teeth 412. When the passive ring 413 rotates forward, its triangular teeth 412 engage with the clamping plate 411, driving the passive wheel 404 to rotate synchronously. When the passive ring 413 rotates reversely, the slope surface of the triangular teeth 412 and the end base of the clamping plate 411 cause the clamping plate 411 to rotate toward the direction of the passive wheel 404. At this time, the passive ring 413 cannot drive the passive wheel 404 to rotate synchronously.

[0049] An extension plate 406 is fixedly mounted on the outer surface of the air guide tube 401. A rectangular hole is formed on the outer surface of the extension plate 406. A passive block 408 is inserted into the rectangular hole. The passive block 408 can move freely in the rectangular hole, and a telescopic rod 407 is rotatably mounted on the outer surface of the passive block 408 through a rotating shaft. The telescopic end of the telescopic rod 407 is rotatably connected to the passive plug 402. In a default state, the telescopic rod 407 is in a fully extended state. Two locking rods 405 are rotatably mounted on the outer surface of the extension plate 406 through a rotating shaft. Two traction plates 409 are rotatably mounted on the outer surface of the passive block 408. The ends of the traction plates 409 are rotatably connected to the outer surfaces of the locking rods 405. In a default state, the traction plates 409 and the locking rods 405 are perpendicular to each other. When the passive block 408 moves toward the direction close to the air guide tube 401, the traction plates 409 change from a vertical state to an inclined state. Therefore, the locking rod 405 rotates upward under the traction force of the traction plates 409.

[0050] A plurality of locking blocks 410 are fixedly installed on the outer surface of the passive wheel 404. The locking blocks 410 are arranged in a ring shape, and the end of the locking rod 405 is triangular. When the passive wheel 404 rotates forward, the locking blocks 410 contact the inclined surface of the locking rod 405, so that after the locking blocks 410 rotate, they return to their initial state under the traction force of the telescopic rod 407.

[0051] like Figure 2 、 Figure 12 As shown, a driving gear 207 is fixedly sleeved on the upper end of the winding 203, and the driving gear 207 is located in the outer casing 201. The driving gear 207 and the driving gear 207 inside the opposite outer casing 201 are tensioned by a toothed belt 103. The two bottom plates 101 above the transport trolley 1 are connected by two folding rods 104. The center folded parts of the two folding rods 104 are rotatably installed with tensioning wheels 105. The tensioning wheel 105 is inserted into the toothed belt 103. When the two bottom plates 101 approach each other, the folding action of the folding rod 104 causes the tensioning wheel 105 to approach synchronously, thereby tensioning and expanding the toothed belt 103, effectively preventing the toothed belt 103 from failing in transmission when the spacing between the bottom plates 101 is reduced.

[0052] The tightness of the toothed belt 103 is automatically adjusted through mechanical linkage to ensure stable and reliable power transmission of the transmission system under different working conditions, while also being able to load semi-finished panels of different sizes.

[0053] The working principle of the present invention is:

[0054] When taking out the semi-finished plate, the pull rod 4 is pulled intermittently, so that the bottom end of the pull rod 4 drives the driving rod 302 to move toward the inside of the air cylinder 301. At this time, the movable plug 303 squeezes the air into the inside of the movable tube 304 and begins to squeeze the air guide column 309 to move. Then the air comes to the inside of the air guide tube 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 resets, the passive plug 402 returns to its initial state under the elastic force of the auxiliary spring 403. Then, in the process of pulling the pull rod 4, it moves toward the direction close to the passive ring 413. When the passive ring 413 rotates, its triangular teeth 412 engage with the clamping plate 411, driving the passive wheel 404 to rotate synchronously, and winding the driving rope 204 around the outer surface of the passive wheel 404.

[0055] The driving rope 204 is pulled to rotate the winding 203, which compresses the torsion spring 206 during the rotation. Then the spiral rod 202 starts to rotate, causing the semi-finished plate inside the baffle 2 to move upward, and then the worker can take out the semi-finished plate.

[0056] When the baffle 2 is placed inside the baffle 2, since the torsion spring coil 206 is in a compressed state, when the pull rod 4 is pushed toward the baffle 2, the driving rod 302 moves in the direction away from the air cylinder 301, and then the movable plug 303 pulls the movable tube 304 to move through the traction line 305. Since the chamber between the air cylinder 301 and the passive plug 402 is in a closed state, the passive plug 402 moves 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, it pulls the passive block 408 to move through the telescopic rod 407. At this time, the passive block 408 moves toward the direction close to the air guide tube 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, and the passive wheel 404 rotates in the opposite direction under the traction force of the driving rope 204.

[0057] The screw rod 202 also starts to rotate at this time, and drives the semi-finished plate to move downward. After the pressure on the pull rod 4 is finished, the screw rod 202 also stops rotating. The above actions are repeated continuously to realize the loading of the semi-finished plate.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
