[0002] Prefabricated components refer to steel, wood or concrete components that are prefabricated in a factory or on-site according to design specifications. They can be further subdivided according to different process characteristics. For example, prefabricated composite slabs include prefabricated prestressed composite slabs, prefabricated truss reinforced composite slabs, prefabricated ribbed prestressed composite slabs (PK slabs), etc. Frame-type prefabricated components are also a commonly used type. After the production of frame-type prefabricated components is completed, the strength of the finished frame-type prefabricated components needs to be monitored to ensure the safety of the subsequent use of the frame-type prefabricated components.

[0014] Preferably, a method for using a strength monitoring device for producing frame-type prefabricated components comprises the following steps:

[0015] 1. First, place the frame-type prefabricated components one by one on the conveyor belt of the conveyor belt device. When the first group of frame-type prefabricated components moves to the bottom of the extrusion block, control the second hydraulic cylinder to extend, so that the two groups of placement plates cooperate with the U-shaped plates to clamp and fix the two ends of the frame-type prefabricated components;

[0016] Second, the first hydraulic cylinder is controlled to extend, so that the lifting frame and the extrusion block are lowered together, until the bottom of the extrusion block is tightly against the frame-type prefabricated component, and then the pressure on the frame-type prefabricated component is monitored in real time through the pressure sensor;

[0017] 3. After the strength monitoring of the first group of frame-type prefabricated components is completed, the second hydraulic cylinder is controlled to be shortened to allow the frame-type prefabricated components to fall back onto the conveyor belt of the conveyor device. At the same time, the first hydraulic cylinder is controlled to be shortened to drive the lifting frame to rise, forcing the two groups of clamping plates to approach each other. The frame-type prefabricated components located between the two groups of clamping plates on the conveyor belt of the conveyor device will be automatically centered on the conveyor belt of the conveyor belt device.

[0018] Fourth, the conveyor belt device is then controlled to drive the frame type prefabricated components to move until the second group of frame type prefabricated components moves to the bottom of the extrusion block, and the operation is repeated to continuously monitor the strength of the frame type prefabricated components;

[0019] 5. When the frame-type prefabricated components with qualified strength are about to fall from the transmission belt, the electric lifting rod is controlled to extend, and the guide plate is turned outward with its hinge axis as the axis, so that the qualified frame-type prefabricated components fall to the inner bottom of the bottom bin along the guide plate, and the unqualified frame-type prefabricated components fall directly to the ground, separating the qualified products from the unqualified products.

[0020] Compared with the prior art, the present invention provides a strength monitoring device for the production of frame-type prefabricated components and a method for using the same, which has the following beneficial effects:

[0021] 1. The present invention clamps and fixes the frame-type prefabricated component through the cooperation of the placement plate and the U-shaped plate. If the length of the frame-type prefabricated component is long, the double-axis motor can be controlled to drive the threaded rod to rotate clockwise, and the thread action is used to force the connecting plate to drive the second hydraulic cylinder to move to both sides of the bottom bin, and the second slider slides inside the second slide groove, so that the two groups of placement plates are separated from each other, increasing the distance between the two, and the two ends of the frame-type prefabricated component with a long length can be fixed. If the two ends of the prefabricated component are not clamped and fixed, the position of the placement plate at the bottom of the prefabricated component can be adjusted according to needs, so that the prefabricated component can be clamped and fixed at different positions, so that the device can monitor the strength data of the frame-type prefabricated component under different clamping conditions, thereby improving the application range of the entire device.

[0022] 2. When monitoring the strength of the frame-type prefabricated components, the present invention can place the frame-type prefabricated components one by one on the conveyor belt of the conveyor belt device. When the first group of frame-type prefabricated components moves to the right below the extrusion block, the second hydraulic cylinder is controlled to extend until the two groups of placement plates cooperate with the U-shaped plates to clamp and fix the two ends of the frame-type prefabricated components. Then, the first hydraulic cylinder is controlled to extend to allow the lifting frame to descend with the extrusion block until the bottom of the extrusion block is tightly against the frame-type prefabricated components, and the pressure on the frame-type prefabricated components is monitored in real time through the pressure sensor. After the strength monitoring of the first group of frame-type prefabricated components is completed, the second hydraulic cylinder is controlled to shorten so that the frame-type prefabricated components fall back onto the conveyor belt of the conveyor belt device, and then the conveyor belt device is controlled to drive the frame-type prefabricated components to move until the second group of frame-type prefabricated components moves to the right below the extrusion block. The strength of the frame-type prefabricated components is repeatedly monitored in this way. During the process, the operator only needs to continuously move to the conveyor belt of the conveyor belt device, so that the device can continuously monitor the strength of the frame-type prefabricated components, thereby improving the monitoring efficiency of the entire device.

[0023] 3. In the present invention, when the first hydraulic cylinder is shortened to drive the lifting frame to rise, the connecting rod drives the two groups of moving blocks to approach each other, thereby driving the two groups of clamping plates to approach each other. During the process, the frame-type prefabricated component located between the two groups of clamping plates on the conveyor belt device will be automatically centered. After that, the frame-type prefabricated component located in the middle position on the conveyor belt moves to the bottom of the extrusion block as the conveyor belt rotates, thereby ensuring the accuracy of the device's monitoring of the strength data of the frame-type prefabricated component. When the first hydraulic cylinder drives the lifting frame to descend, the two groups of clamping plates will move away from each other again. This process is repeated, and the position of each group of frame-type prefabricated components can be continuously centered. There is no need to manually center the position of the frame-type prefabricated components, thereby reducing the labor intensity of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Furthermore, a method for using a strength monitoring device for producing frame-type prefabricated components is provided, and the steps of the method for using the device are as follows:

[0046] 1. First, the frame-type prefabricated components are placed one by one on the conveyor belt of the conveyor belt device 13. When the first group of frame-type prefabricated components moves to the right below the extrusion block 11, the second hydraulic cylinder 902 is controlled to extend, so that the two groups of placement plates 901 cooperate with the U-shaped plate 10 to clamp and fix the two ends of the frame-type prefabricated components;

[0047] Second, the first hydraulic cylinder 3 is controlled to extend, so that the lifting frame 12 and the extrusion block 11 are lowered together, until the bottom of the extrusion block 11 is tightly against the frame-type prefabricated component, and then the pressure on the frame-type prefabricated component is monitored in real time through the pressure sensor 18;

[0048] 3. After the strength monitoring of the first group of frame-type prefabricated components is completed, the second hydraulic cylinder 902 is controlled to be shortened, so that the frame-type prefabricated components fall back onto the conveyor belt of the conveyor belt device 13. At the same time, the first hydraulic cylinder 3 is also controlled to be shortened, so as to drive the lifting frame 12 to rise, forcing the two groups of clamping plates 503 to approach each other, and the frame-type prefabricated components located between the two groups of clamping plates 503 on the conveyor belt of the conveyor belt device 13 will be automatically centered on the conveyor belt of the conveyor belt device 13;

[0049] Fourth, the conveyor belt device 13 is then controlled to drive the frame-type prefabricated components to move until the second group of frame-type prefabricated components moves to the bottom of the extrusion block 11, and the operation is repeated to continuously monitor the strength of the frame-type prefabricated components;

[0050] 5. When the frame-type prefabricated components with qualified strength are about to fall from the transmission belt, the electric lifting rod 15 is controlled to extend, and the guide plate 14 is turned outward with its hinge axis as the axis, so that the qualified frame-type prefabricated components fall to the inner bottom of the bottom bin 8 along the guidance of the guide plate 14, and the unqualified frame-type prefabricated components fall directly to the ground, so that the qualified products are separated from the unqualified products.

[0051] Embodiment 1, as Figure 1-3 and Figure 5-6 As shown, when centering the frame-type prefabricated components of different lengths, if the length of the frame-type prefabricated component is longer, the control drive mechanism 4 drives the two sets of screw rods 1 to rotate clockwise synchronously, and uses the threaded action to force the limit plate 2 to gradually descend, thereby limiting the highest position to which the lifting frame 12 can rise. In this way, it is possible to avoid excessive squeezing pressure of the two sets of clamping plates 503 on the frame-type prefabricated components, causing damage to the frame-type prefabricated components. On the contrary, if the length of the frame-type prefabricated component is shorter, the control drive mechanism 4 drives the two sets of screw rods 1 to rotate counterclockwise, so that the position of the limit plate 2 rises, and the effective minimum distance between the two sets of clamping plates 503 can be reduced again, which is convenient for clamping and centering the shorter frame-type prefabricated components.

[0052] Embodiment 2, as Figure 1-6 and Fig. 9 As shown, in the process of shortening the first hydraulic cylinder 3 and driving the lifting frame 12 to rise, the connecting rod 504 drives the two groups of moving blocks 501 to approach each other, and the moving blocks 501 also slide on the sliding rod 502, thereby driving the two groups of clamping plates 503 to approach each other, and the frame-type prefabricated components located between the two groups of clamping plates 503 on the conveyor belt device 13 will be clamped by the two groups of clamping plates 503 and automatically centered, and then the frame-type prefabricated components located in the middle position on the conveyor belt will move to the bottom of the extrusion block 11 as the conveyor belt rotates, thereby ensuring the accuracy of the device's monitoring of the strength data of the frame-type prefabricated components, and when the first hydraulic cylinder 3 drives the lifting frame 12 to descend, the two groups of clamping plates 503 will move away from each other, and this process is repeated, so that the position of each group of frame-type prefabricated components can be continuously centered.

[0053] Working principle: before use, the device is powered on. First, the frame prefabricated components are placed one by one on the conveyor belt of the conveyor belt device 13. When the first group of frame prefabricated components moves to the bottom of the extrusion block 11, the second hydraulic cylinder 902 is controlled to extend until the two groups of placement plates 901 cooperate with the U-shaped plate 10 to clamp and fix the two ends of the frame prefabricated components. Then the first hydraulic cylinder 3 is controlled to extend to allow the lifting frame 12 to descend with the extrusion block 11. During the process, the first slider 17 slides downward inside the first slide groove 16 until the bottom of the extrusion block 11 is tightly against the frame prefabricated component. Then, the pressure on the frame prefabricated component is monitored in real time through the pressure sensor 18. After the pressure sensor 18 reaches the specified pressure value, if the frame prefabricated component is not damaged, the strength of the frame prefabricated component is qualified, otherwise it is unqualified. After the strength monitoring of the first group of frame prefabricated components is completed, the second hydraulic cylinder 902 is controlled to shorten so that the frame prefabricated component falls back onto the conveyor belt of the conveyor belt device 13, and the first The hydraulic cylinder 3 is also shortened, driving the lifting frame 12 to rise. During the process, the connecting rod 504 drives the two groups of moving blocks 501 to approach each other, thereby driving the two groups of clamping plates 503 to approach each other, and the frame-type prefabricated components located between the two groups of clamping plates 503 on the conveyor belt device 13 will automatically be centered on the conveyor belt device 13, and then the conveyor belt device 13 is controlled to drive the frame-type prefabricated components to move until the second group of frame-type prefabricated components moves to the right below the extrusion block 11, and this can be repeated continuously. The strength of the frame prefabricated components is monitored regularly. When the qualified frame prefabricated components on the conveyor belt device 13 are about to fall from the transmission belt, the electric lifting rod 15 is controlled to extend, and the guide plate 14 is turned outward with its hinge axis as the axis, so that the qualified frame prefabricated components fall to the inner bottom of the bottom warehouse 8 along the guidance of the guide plate 14, and the unqualified frame prefabricated components fall directly to the ground, so that the qualified products are separated from the unqualified products, and the qualified products collected at the bottom of the bottom warehouse 8 are regularly packed in batches.

1. First, the frame-type prefabricated components are placed one by one on the conveyor belt of the conveyor belt device (13). When the first group of frame-type prefabricated components moves to the position directly below the extrusion block (11), the second hydraulic cylinder (902) is controlled to extend, so that the two groups of placement plates (901) cooperate with the U-shaped plates (10) to clamp and fix the two ends of the frame-type prefabricated components; Second, the first hydraulic cylinder (3) is controlled to extend, so that the lifting frame (12) and the extrusion block (11) are lowered together, until the bottom of the extrusion block (11) is tightly pressed against the frame-type prefabricated component, and then the pressure on the frame-type prefabricated component is monitored in real time through the pressure sensor (18); 3. After the strength monitoring of the first group of frame-type prefabricated components is completed, the second hydraulic cylinder (902) is controlled to be shortened, so that the frame-type prefabricated components fall back onto the conveyor belt of the conveyor belt device (13). At the same time, the first hydraulic cylinder (3) is controlled to be shortened, so as to drive the lifting frame (12) to rise, so as to force the two groups of clamping plates (503) to approach each other. The frame-type prefabricated components located between the two groups of clamping plates (503) on the conveyor belt of the conveyor belt device (13) will be automatically centered on the conveyor belt of the conveyor belt device (13); Fourth, the conveyor belt device (13) is then controlled to drive the frame-type prefabricated components to move until the second group of frame-type prefabricated components moves to the bottom of the extrusion block (11), and the operation is repeated to continuously monitor the strength of the frame-type prefabricated components; 5. When the frame-type prefabricated components with qualified strength are about to fall from the transmission belt, the electric lifting rod (15) is controlled to extend, so that the guide plate (14) is turned outward with its hinge axis as the axis, so that the qualified frame-type prefabricated components fall to the inner bottom of the bottom bin (8) along the guidance of the guide plate (14), and the unqualified frame-type prefabricated components fall directly to the ground, thereby separating the qualified products from the unqualified products.
