Description

Technical Field

[0001] This utility model relates to the field of PC board storage technology, specifically to an assembled PC board placement rack. Background Technology

[0002] Precast precast concrete (PC) panels are precast concrete components. A precast PC panel support frame is a support structure specifically designed for building applications to install and support precast PC panels. This structure is typically composed of precast metal or plastic components and features a simple assembly and installation process.

[0003] A search revealed that Chinese patent CN204822551U discloses a prefabricated building PC board placement rack. The patent describes a technical solution that uses two or more placement racks working together to create a lightweight, simple, and space-saving structure that effectively protects the PC boards from damage during storage and facilitates the stacking and hoisting of the PC boards.

[0004] In this solution, the width and length of prefabricated PC panels vary depending on their application in construction. The placement rack in this solution only considers the length of the prefabricated PC panels but not their width. Therefore, the device cannot be used when the width varies, making it impossible to place prefabricated PC panels of different widths into the placement rack, thus affecting work efficiency. To solve this technical problem, this utility model proposes a prefabricated PC panel placement rack. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This utility model provides an assembled PC board placement rack. It has the following beneficial effects:

[0017] (1) The motor drives the movement of the connecting block one through the operation of the bidirectional threaded rod, thereby causing the top plate to move up and down under the limit of the slide groove one. The movement of the top plate is limited by the fixed block to ensure the consistency of direction. At the same time, the start of the electric push rod drives the movement of the slider one and the clamping plate. The clamping plate maintains the consistency of movement direction under the cooperation of the slide groove two and the slider two. This cooperative mechanism realizes the effect of precise positioning and fixing of assembled PC boards of different widths and lengths, solves the problem that the traditional placement rack cannot effectively place different assembled PC boards, and improves work efficiency and accuracy.

[0018] (2) The clamp is connected to the connecting block 2 by a pin. The inner groove allows the connecting block 2 to move freely inside. Once the pin is fixed, the placement plate can be placed stably on the connecting block 2. The anti-slip pad ensures the stable placement of the object. The insertion hole is used for the accurate positioning of the pin to ensure the firm fixation of the connecting block 2. This synergistic effect realizes the stacking effect of assembled PC boards of different thicknesses, solves the problem that the existing assembled PC board placement rack has a fixed stacking width spacing and cannot adapt to the stacking of assembled PC boards of different thicknesses, and improves work efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] Example 1: A prefabricated PC board placement rack includes a rack body 1. A motor 2 is fixedly connected to the front outer wall of the rack body 1. A bidirectional threaded rod 3 is fixedly connected to the output end of the motor 2. The bidirectional threaded rod 3 is rotatably connected to the left side of the rack body 1. Connecting blocks 4 are threaded to the outer walls of both ends of the bidirectional threaded rod 3. A top plate 5 is fixedly connected to the top wall of the connecting blocks 4. Sliding grooves 6 are provided on both sides of the top of the rack body 1, and the connecting blocks 4 are slidably connected in the sliding grooves 6. A positioning block 25 is fixedly connected to the bottom of the other end of the top plate 5. A connecting rod 20 is fixedly connected to the right side of the rack body 1, and the positioning block 25 is slidably connected to the outer wall of the connecting rod 20. 5. Fixed blocks 7 are fixedly connected to both sides of the top. Electric push rods 8 are rotatably connected inside the fixed blocks 7. Slider 9 is rotatably connected to the output end of the electric push rods 8. At the same time, a pair of clamping plates 10 are provided on the top of the top plate 5. Slide grooves 11 are opened on the outer sides of the clamping plates 10. Slider 9 is shaped like the earth and is engaged in slide grooves 11. Slider 9 is slidably connected in slide grooves 11. Slider 12 is fixedly connected to the bottom of the clamping plate 10. A pair of slide grooves 13 are opened on the top of the top plate 5. Slider 12 is shaped like the H and is engaged in slide grooves 13. Slider 12 is slidably connected in slide grooves 13. At the same time, clamping plate 10 is slidably connected to the top of the top plate 5.

[0028] The motor 2 is started, causing the bidirectional threaded rod 3 to rotate inside the placement frame body 1, thereby driving the connecting block 4 to move in the opposite direction. The movement of the connecting block 4 causes the top plate 5 to move in the opposite direction accordingly. The consistent movement direction of the top plate 5 is ensured by the limiting of the slide groove 6 and the bottom positioning block 25. Once the two sides of the top plate 5 have moved to the same length as the assembled PC board, they are adjusted according to the width of the PC board. The electric push rods 8 on the fixing blocks 7 on both sides of the top plate 5 are started, pushing the clamping plate 10 on the slider 9 to move inward. At the same time, the clamping plate 10 moves under the limiting of the slider 12, ensuring the consistency of the movement direction. This design allows for the accurate placement of assembled PC boards of different sizes, improving work efficiency and accuracy.

[0029] Example 2: The difference between this example and Example 1 is that multiple placement plates 17 are provided on the inner sidewalls of the two side clamps 10, and anti-slip pads 18 are fixedly connected to the top of each placement plate 17. A pair of inner grooves 14 are opened on the inner sidewalls of the clamps 10, and a pair of connecting blocks 15 are fixedly connected to the outer sidewalls of the placement plates 17. The connecting blocks 15 correspond to the inner grooves 14 and are slidably connected in the inner grooves 14. Insertion holes 19 are opened on both the connecting blocks 15 and the sidewalls of the clamps 10. A pin 16 is provided on the outside of the clamps 10 and is slidably connected in the insertion hole 19. A base plate 21 is fixedly connected to the bottom of the placement rack body 1. Connecting frames 22 are fixedly connected to both sides of the base plate 21. An electric hydraulic rod 23 is fixedly connected to the bottom of the connecting frame 22. Multiple casters 24 are fixedly connected to the bottom of the base plate 21.

[0030] Depending on the thickness of the assembled PC board, the distance between the placement plates 17 on the clamping plate 10 is adjusted by pulling out the pin 16. First, all placement plates 17 except the bottom one are removed, and then the assembled PC board is placed on the bottom placement plate 17, with the anti-slip pad 18 ensuring stability. Subsequently, placement plates 17 are inserted layer by layer and secured with the pins 16 to ensure the safe placement of multiple assembled PC boards and prevent friction. During movement, the electric hydraulic rod 23 on the connecting frame 22 is activated, causing the casters 24 to touch the ground, thereby moving and fixing the placement frame body 1. This design improves the practicality and work efficiency of the placement frame body 1, ensuring the safe placement and movement of the assembled PC boards.

[0031] During operation, the placement rack body 1 needs to be adjusted according to the length and width of the assembled PC board. First, the motor 2 is started. Under the action of the motor 2, the bidirectional threaded rod 3 rotates inside the left side of the placement rack body 1. The rotation of the bidirectional threaded rod 3 drives the connecting blocks 4 at both ends to move in the opposite direction. When the connecting blocks 4 move, they will drive the top plates 5 on their respective tops to move in the opposite direction on the placement rack body 1. At the same time, they are limited by the sliding grooves 6 opened on both sides. The other side of the top plate 5 is limited by the bottom positioning block 25 on the connecting rod 20 inside the right side of the placement rack body 1. This makes The top plate 5 maintains a consistent direction during movement. After both top plates 5 move to the same length as the assembled PC board, they are adjusted according to the width of the assembled PC board. By activating the electric push rods 8 on the fixing blocks 7 on both sides of the top plate 5, the electric push rods 8 will push the clamping plate 10 on the slider 1 9 to move inward. At the same time, the slider 1 9 will be limited and slide in the slide groove 2 11, causing a jamming phenomenon when pushing the clamping plate 10 to move. At this time, the clamping plate 10 moves towards the edge of the assembled PC board under the action of the electric push rods 8. The clamping plate 10 is limited in the slide groove 3 by the slider 2 12. Within 13, the clamping plates 10 move in the same direction. Through their cooperation, the effect of placing assembled PC boards of different lengths and widths is achieved, improving work efficiency. Since there are many assembled PC boards, in order to save the number of placement rack bodies 1, multiple assembled PC boards will be stacked on the placement rack body 1. At this time, according to the thickness of the assembled PC board, the distance between the placement plates 17 on the clamping plates 10 is adjusted. First, the pin 16 is pulled out, and all the upper placement plates 17 are removed, leaving the bottom placement plate 17. Then, the assembly... The prefabricated PC boards are placed on the bottom placement plate 17, and the anti-slip pad 18 provides an anti-slip effect. The placement plate 17 is inserted again and the pin 16 is inserted to fix it. Through their cooperation, the placement rack body 1 can hold multiple prefabricated PC boards without friction, which improves the practicality and work efficiency of the placement rack body 1. When moving, the electric hydraulic rod 23 on the connecting frame 22 is activated. At this time, the electric hydraulic rod 23 retracts, causing the caster 24 to land and move. The caster 24 lowers to support and fix the placement rack body 1.
