Description

Technical Field

[0001] This utility model relates to the field of precast wall panel production technology, and more specifically, to a dual-function conveying platform. Background Technology

[0002] In automated production lines for precast wall panels, specialized conveying equipment is required to transport wall panel components (wall bricks are crucial parts of precast wall panels, hence also referred to as wall panel components in the industry) so that they can be processed by various equipment during transport. These specialized conveying devices typically use conveyor belts that can only transport components in a straight line. At certain specific equipment nodes, small wall panel components can be transported straight into the equipment, while large components require a 90-degree turn before being transported (the size of the wall panel components depends on the area; different models of precast wall panels use different sizes of wall panel components). This necessitates modifications to the equipment used to transport wall panel components to meet diverse transport requirements, leading to this design. Utility Model Content

[0003] The purpose of this utility model is to address the needs of the prior art and provide a dual-function conveying platform. This utility model is designed with a movable reversing frame to meet the reversing conveying requirements of large wall panel components. This utility model has both linear conveying and reversing conveying functions, which can meet the conveying requirements of different types of wall panel components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-function conveying platform includes a platform support, a U-shaped frame, a first long roller group, a second long roller group, and a roller transmission mechanism. The U-shaped frame is fixedly installed on the top of the platform support and includes two parallel box beams. The length direction of the box beams is set as the conveying direction of the wall panel components. The first and second long roller groups are installed inside the U-shaped frame and are respectively located at the beginning and end of the conveying direction of the wall panel components. A reversing frame is installed between the first and second long roller groups. The reversing frame is cross-shaped, and four short roller groups are filled and installed around the reversing frame. The roller transmission mechanism drives and connects the first long roller group, the second long roller group, and all the short roller groups. A reversing drive mechanism is installed below the reversing frame and is driven and connected to the reversing frame.

[0006] Furthermore, the first long roller group, the second long roller group, and all the short roller groups are installed at the same height, and the initial height of the reversing frame is lower than the installation height of the first long roller group, the second long roller group, and all the short roller groups.

[0007] Furthermore, the first long roller group, the second long roller group, and all the short roller groups each include several rotatably mounted roller bodies. Each roller body has a shaft head extending into the box beam. Each roller body has two transmission gears mounted on its shaft head. Adjacent roller bodies are connected by a chain drive, and the chain meshes with the transmission gears. The first long roller group includes a first long roller body and a second long roller body. The roller body transmission mechanism includes a motor, and the output end of the motor is connected to the shaft head of the first long roller body.

[0008] Furthermore, two symmetrically arranged bottom horizontal plates are connected and installed below the two box beams. Four vertical support plates are installed on the bottom horizontal plates, and the four vertical support plates are respectively set for four short roller groups. One end of the roller body of the short roller group is installed on the vertical support plate.

[0009] Furthermore, the reversing frame includes a center plate located at the center of the reversing frame. A main shaft is fixedly connected below the center plate. The main shaft has a splined section. The reversing drive mechanism includes a lifting assembly, which includes a cylinder seat and a rotating tube. A functional platform is provided inside the platform support. The cylinder seat is fixedly installed on the functional platform. The rotating tube is vertically and rotatably installed on the cylinder seat. The rotating tube is vertically continuous and has a splined hole inside. The splined section of the main shaft is matched and inserted into the splined hole. A first push cylinder is installed below the cylinder seat. The first push cylinder is installed vertically upward, and the piston rod end of the first push cylinder is inserted into and extends into the splined hole.

[0010] Furthermore, a limiting disk is connected to the outer wall of the spindle, the spline segment is located below the limiting disk, and the diameter of the limiting disk is larger than the diameter of the spline hole.

[0011] Furthermore, the reversing drive mechanism also includes a reversing assembly, which includes a second push cylinder and a rack. The second push cylinder is installed laterally, and the rack is connected to the piston rod end of the second push cylinder. A transmission gear ring is connected to the outer wall of the rotating tube, and the rack meshes with the transmission gear ring.

[0012] Furthermore, a linkage plate is fixedly connected to the side of the rack, and two limit rods are vertically installed on the functional platform. The two limit rods are located on the movement trajectory line of the linkage plate, and the linkage plate moves between the two limit rods.

[0013] Furthermore, the distance between the two limiting rods determines the single stroke of the rack, and the single stroke of the rack drives the rotating tube to rotate ninety degrees.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5The dual-function conveying platform shown includes a platform support 1, a U-shaped frame 2, a first long roller group 3, a second long roller group 4, and a roller transmission mechanism 7. The U-shaped frame 2 is fixedly installed on the top of the platform support 1. The U-shaped frame 2 includes two parallel box beams 21. In this invention, the length direction of the box beams 21 is set as the conveying direction of the wall panel components (i.e., Figure 1 (In the direction of the arrow in the image), the first long roller group 3 and the second long roller group 4 are installed inside the U-shaped frame 2. The first long roller group 3 and the second long roller group 4 are respectively located at the beginning and end of the conveying direction of the wall panel component. In order to meet the turning requirements of large wall panel components, a reversing frame 5 is installed between the first long roller group 3 and the second long roller group 4. A reversing drive mechanism 8 is installed below the reversing frame 5. The reversing drive mechanism 8 is connected to the reversing frame 5 for transmission. The reversing frame 5 can independently support large wall panel components. The reversing drive mechanism 8 can push the reversing frame 5 upward to lift the wall panel component. Then, the reversing frame 5 rotates to achieve the reversing rotation of the wall panel component. The reversing frame 5 is cross-shaped, and four short roller groups 6 are respectively filled and installed around the reversing frame 5. The short roller groups 6 are arranged parallel to the first long roller group 3 and the second long roller group 4. In the initial state, the height of the reversing frame 5 is lower than that of the short roller groups 6, the first long roller group 3 and the second long roller group 4. The short roller groups 6, the first long roller group 3 and the second long roller group 4 are installed at the same height. The wall panel components can be smoothly transferred by being lifted by the short roller group 6, the first long roller group 3, and the second long roller group 4. The roller transmission mechanism 7 drives the first long roller group 3, the second long roller group 4, and all the short roller groups 6 to rotate synchronously, so as to realize the linear conveying motion of the wall panel components lifted above. When encountering large wall panel components, the lifting reversing frame 5 can be operated. After the reversing frame 5 is lifted, it can pass the short roller group 6 and the first long roller group 4. The installation height of the long roller group 3 and the second long roller group 4 is such that the wall panel component is lifted on the reversing frame 5 to achieve a 90-degree reversal. After the reversal, the reversing frame 5 is lowered, so that the wall panel component is once again supported by the short roller group 6, the first long roller group 3 and the second long roller group 4, so as to achieve the output of the wall panel component after the reversal. After the reversing frame 5 is raised, it can exceed the installation height of the short roller group 6, the first long roller group 3 and the second long roller group 4. After the reversing frame 5 is lowered, it can be lower than the installation height of the short roller group 6, the first long roller group 3 and the second long roller group 4.

[0024] like Figure 2As shown, the first long roller group 3, the second long roller group 4, and all the short roller groups 6 of this utility model include several rotatably mounted roller bodies. The only difference is that the length of the roller body in the short roller group 6 is shorter than that in the long roller group. Each roller body has a shaft extending into the box beam 21. For the first long roller group 3 and the second long roller group 4, both ends of the roller body are rotatably connected to the two box beams 21 respectively. For the short roller group 6, one end of the roller body is rotatably connected to the corresponding box beam 21. Two transmission gears 72 are mounted on the shaft of each roller body. Adjacent roller bodies are connected by a chain 73, which meshes with the transmission gears 72. The purpose of designing two transmission gears 72 is to enable the chain 73 to mesh alternately. The first long roller group 3 includes a first long roller body 31 and a second long roller body 32. The roller transmission mechanism 7 includes a motor 71. The output end of the motor 71 is connected to the shaft head of the first long roller body 31 (coupling connection). The second long roller body 32 is first connected to the chain of the first long roller body 31. Then, transmission gears 72 are installed on both shaft heads of the second long roller body 32. This allows for the transmission of two parallel short roller groups 6. In this invention, the top of the box beam 21 is designed as a detachable top cover plate. After the top cover plate is removed, it is convenient to install and connect the gears and chains.

[0025] One end of the roller body of short roller group 6 is rotatably connected to box beam 21. To address the installation requirements at the other end of the roller body of short roller group 6, such as... Figure 2 and Figure 3 As shown, two symmetrically arranged bottom horizontal plates 22 are connected and installed below the two box beams 21. Four vertical support plates 23 are installed on the bottom horizontal plates 22. The four vertical support plates 23 are respectively set for four short roller groups 6. One end of the roller body of the short roller group 6 is rotatably installed on the vertical support plate 23. The installation of the bottom horizontal plates 22 should not affect the lifting and lowering movement of the reversing frame 5. The crossbar of the reversing frame 5 does not collide with the bottom horizontal plates 22 during the descent.

[0026] like Figure 1 and Figure 4As shown, the commutator 5 includes a center plate 51, which is located at the center of the commutator 5. The center plate 51 is a square plate, and a set of crossbars is connected to each of the four sides of the center plate 51. A main shaft 52 is fixedly connected to the bottom of the center plate 51. The main shaft 52 is provided with a spline section 521. The commutator drive mechanism 8 includes a lifting assembly 81, which includes a cylinder seat 811 and a rotating tube 812. A function table 11 is provided inside the platform support 1. The cylinder seat 811 is fixedly installed on the function table 11, and the rotating tube 812 is vertically and rotatably installed on the cylinder seat 811. The rotating tube 812 is vertically continuous, and a splined hole 8121 is provided inside the rotating tube 812. The splined section 521 of the main shaft 52 is inserted into the splined hole 8121. The length of the splined hole 8121 is greater than the length of the splined section 521. A first push cylinder 813 is installed below the cylinder seat 811. The first push cylinder 813 is installed vertically upwards. The piston rod end of the first push cylinder 813 is inserted into and extends into the splined hole 8121. The first push cylinder 813 is a hydraulic push cylinder to generate a large thrust to lift the reversing frame 5 and the large wall panel components above it. After the piston rod rises, it can lift the main shaft 52, thus creating the lifting effect of the reversing frame 5. The extension length of the piston rod of the first push cylinder 813 is no more than half the length of the spline section 521 of the main shaft 52. In this way, the spline section 521 of the main shaft 52 always maintains more than half of its length engaged with the rotating tube 812. After the reversing frame 5 is lifted, the reversing frame 5 is completely higher than the highest point of the short roller group 6, the first long roller group 3, and the second long roller group 4. In this way, the steering of the reversing frame 5 is not affected. After the piston rod of the first push cylinder 813 retracts, the reversing frame 5 is subjected to weight. Under the action of force, it automatically descends and resets. The outer wall of the main shaft 52 is connected to the limiting plate 522. The spline section 521 is located below the limiting plate 522. The diameter of the limiting plate 522 is larger than the diameter of the spline hole 8121. The limiting plate 522 determines the descent depth of the reversing frame 5. When the limiting plate 522 contacts the top of the rotating tube 812, the reversing frame 5 descends to the correct position. The reversing frame 5 sinks and is hidden below the highest point of the short roller group 6, the first long roller group 3, and the second long roller group 4, so that the wall panel component is supported by the short roller group 6, the first long roller group 3, and the second long roller group 4.

[0027] like Figure 3 and Figure 5As shown, the reversing drive mechanism 8 also includes a reversing assembly 82, which includes a second push cylinder 821 and a rack 822. The second push cylinder 821 is horizontally fixed, and the rack 822 is connected to the piston rod end of the second push cylinder 821. A transmission gear ring 814 is fixedly connected to the outer wall of the rotating tube 812. The rack 822 meshes with the transmission gear ring 814. The extension and retraction of the piston rod of the second push cylinder 821 can drive the rack 822 to move linearly. Through the meshing relationship between the rack 822 and the transmission gear ring 814, the rotating tube 812 can be rotated. Since the rotating tube 812 and the main shaft 52 of the reversing frame 5 are splinedly connected, the rotation of the rotating tube 812 can also cause the reversing frame 5 to turn. The turning of the reversing frame 5 can drive the wall panel component above it to turn. Since the wall panel component only Since a 90-degree rotation is required, this utility model has a linkage plate 823 fixedly connected to the side of the rack 822. Two limit rods 824 are vertically installed on the function platform 11. The two limit rods 824 are located on the movement trajectory line of the linkage plate 823. The linkage plate 823 moves between the two limit rods 824. The distance between the two limit rods 824 determines the single movement stroke of the rack 822. The rack 822 completes one movement stroke and drives the rotating tube 812 to rotate 90 degrees, which realizes the 90-degree rotation of the reversing frame 5 and the wall panel component. The length of the crossbars around the center plate 51 of the reversing frame 5 is designed to be consistent, so that the reversing frame 5 can be directly lowered and hidden after each 90-degree rotation. The next reversal only needs to be rotated in the opposite direction to the previous reversal.

[0028] like Figure 2 As shown, there are gaps H1 and H2 between adjacent short roller groups 6. H1 and H2 can just accommodate the hidden crossbar of the reversing frame 5. H1 and H2 are both smaller than the width of the small wall panel component. Therefore, the transmission and conveying of the small wall panel component will not stop at the positions of H1 and H2. This utility model is equipped with a vision inspection system. When the vision detects a large wall panel component (the area is generally more than 4 times that of the small wall panel component), the reversing frame 5 can be activated to reverse the direction, and the small wall panel component can pass directly.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
