Description

Technical Field

[0002] Prefabricated panels are the modules or panels used in engineering projects. They are called prefabricated panels because they are prefabricated concrete parts that are produced and processed in the prefabrication yard and transported directly to the construction site for installation. When making prefabricated panels, first use wooden boards to nail a hollow model. After the hollow part of the model is filled with steel bars, the hollow part is filled with cement. After it dries, the wooden boards are knocked off, and what remains is the prefabricated panel. Prefabricated panels have many uses in construction, such as the cement boards covering the ditches beside the highway and the cement boards used as insulation layers on the roof. After the prefabricated panels are made, they must be erected at a certain inclination through a flip device, so that they can be transported while occupying a small space, and can be temporarily erected and stacked on the production line.

[0003] The prior art has the following deficiencies: when the prior flipping device flips the prefabricated panel, the device usually directly rotates to drive the prefabricated panel to flip. The prefabricated panel cannot remain stable during the flipping process, making it easy for the prefabricated panel to slip during the flipping process. At the same time, the prefabricated panel cannot be flipped more than 90° according to different needs, which will affect the flipping and loading and unloading of the prefabricated panel.

[0037] The present invention provides Figure 1A prefabricated panel turning device shown includes a fixing mechanism 1 and further includes:

[0038] The placing mechanism 2 is arranged on the top of the fixing mechanism 1 and is used for placing, flipping, loading and unloading the prefabricated panels;

[0039] The clamping mechanism 3 is arranged on the top of the placing mechanism 2 and is used for clamping the prefabricated board and further turning it over.

[0040] In order to conveniently flip the prefabricated panel, Figure 2 and Figure 4 As shown, the placement mechanism 2 includes two adjusting screws 201 and a rotating worm 203. The two adjusting screws 201 are respectively arranged on the inner walls at both ends of the top of the fixing mechanism 1. The outer walls of one side of the two adjusting screws 201 are fixedly sleeved with a driven worm wheel 202. The rotating worm 203 is arranged on the outer wall of one side of the fixing mechanism 1. A servo motor 204 is arranged at one end of the rotating worm 203. The rotating worm 203 is meshed with the two driven worm wheels 202. The outer sides of the two adjusting screws 201 are threadedly sleeved with a movable seat 205. A traction plate 206 is rotatably installed on the top of each movable seat 205, and a placement plate 208 rotatably installed on the top of the fixing mechanism 1 is arranged on the top of the traction plate 206. The servo motor 204 works through the meshing action between the rotating worm 203 and the driven worm gear 202, so that the two adjusting screws 201 rotate, which can drive the movable seat 205 to move, and then the inclination angle of the placement plate 208 can be adjusted under the traction action of the traction plate 206, so that the prefabricated plate can be flipped.

[0041] In order to keep the prefabricated panel stable on top of the placement plate 208 and further flip it, as shown in FIG. Figure 2 and Figure 5 As shown, the clamping mechanism 3 includes a blocking plate 301, which is rotatably installed on the outer wall of one side of the placement plate 208. The inner wall of the blocking plate 301 is provided with a first hydraulic cylinder 303, and the two output ends of the first hydraulic cylinder 303 are provided with clamping plates 305. Second hydraulic cylinders 307 are provided between the outer walls at both ends of the blocking plate 301 and the placement plate 208. The operation of the first hydraulic cylinder 303 enables the two clamping plates 305 to clamp and fix the prefabricated plate, and the operation of the two second hydraulic cylinders 307 can push the blocking plate 301 to rotate, so that the clamping mechanism 3 can drive the prefabricated plate to further flip, so that the prefabricated plate can remain stable during the flipping process.

[0042] In order to keep the placement plate 208 stable during the rotation process, Figure 2-Figure 4As shown, the fixing mechanism 1 includes a fixed base plate 101, and fixing frames 102 are fixedly installed at both ends of the outer wall of one side of the fixed base plate 101. The tops of the two fixing frames 102 are rotatably connected to the outer walls of both ends of one side of the placement plate 208 respectively. The two fixing frames 102 are rotatably connected to the outer walls of both ends of the placement plate 208, so that the placement plate 208 can stably drive the prefabricated plate to flip.

[0043] In order to keep the movable seat 205 stable during the movement, Figure 2 and Figure 3 As shown, movable grooves 103 are provided at both ends of the top of the fixed base plate 101, and the inner walls of the two movable grooves 103 are rotatably connected to the two adjusting screw rods 201 respectively, and the inner walls of the two movable grooves 103 are movably connected to the outer walls of the two movable seats 205 respectively. The movable grooves 103 can limit the movement of the movable seats 205, so that the traction plate 206 can stably push the placement plate 208 to adjust the tilt angle, and then the prefabricated plate can be conveniently flipped.

[0044] In order to provide power for the rotation of the placement plate 208, as Figure 2-Figure 4 As shown, the outer wall of the fixed base plate 101 on one side away from the fixed frame 102 is rotatably connected to the rotating worm 203, and the outer wall of one end of the fixed base plate 101 is fixedly connected to the servo motor 204. The servo motor 204 and the rotating worm 203 are connected by an output shaft transmission. The two ends of the bottom of the placement plate 208 away from the fixed frame 102 are fixedly installed with fixed seats 207, and the two fixed seats 207 are respectively rotatably connected to the tops of the two traction plates 206. The fixed base plate 101 can install and fix the rotating worm 203 and the servo motor 204. The servo motor 204 works through the meshing action between the rotating worm 203 and the two driven worm wheels 202, so that the two adjusting screws 201 rotate, and then under the rotational connection between the traction plate 206 and the fixed seat 207, the inclination angle of the placement plate 208 can be conveniently adjusted.

[0045] In order to conveniently flip the clamping mechanism 3, Figure 2 and Figure 4-Figure 5 As shown, fixed shafts 209 are fixedly installed on the outer walls at both ends of the placement plate 208, and connecting shafts 306 are fixedly installed on the outer walls at both ends of the blocking plate 301. The outer sides of the two fixed shafts 209 are rotatably connected to the cylinder parts of the two second hydraulic cylinders 307 respectively, and the outer walls of the two connecting shafts 306 are rotatably connected to the output shaft parts of the two second hydraulic cylinders 307 respectively. The fixed shafts 209 and the connecting shafts 306 can be installed on adjacent second hydraulic cylinders 307, and the operation of the two second hydraulic cylinders 307 can push the blocking plate 301 and the clamping plate 305 to flip.

[0046] In order to keep the clamping plate 305 stable during the adjustment process, Figure 2 and Figure 5 As shown, the clamping mechanism 3 includes a mounting groove 302, which is provided on the inner wall of the blocking plate 301, and the middle position of the inner wall of the mounting groove 302 is fixedly connected to the first hydraulic cylinder 303, and the outer walls of the two clamping plates 305 on one side close to the blocking plate 301 are fixedly installed with sliders 304, and the two sliders 304 are respectively fixedly connected to the two output ends of the first hydraulic cylinder 303, and the outer walls of the two sliders 304 are respectively movably connected to the two ends of the inner wall of the mounting groove 302, and the mounting groove 302 can limit the movement of the slider 304, so that the clamping plate 305 remains stable during the adjustment process, so that the clamping plate 305 can stably clamp and fix the prefabricated plate.

[0047] The specific implementation method is as follows: during the production and processing of the prefabricated board, it is necessary to flip it over, and the prefabricated board is placed on the top of the placement plate 208. The first hydraulic cylinder 303 works to make the two sliders 304 move along the inner wall of the installation groove 302, so that the distance between the two clamping plates 305 can be adjusted, so that the two clamping plates 305 can clamp and fix the outer walls of the two ends of the prefabricated board. At the same time, the blocking plate 301 can intercept the prefabricated board, and then the servo motor 204 works to make the rotating worm 203 rotate. Through the transmission action between the worm gears, the two driven worm wheels 202 rotate, and then the two adjusting screw rods 201 rotate, which can drive the two movable seats 205 on their outer sides along the inner walls of the adjacent movable grooves 103 toward the direction of the rotating worm 203. The placing plate 208 is moved, and then under the pushing action of the traction plate 206, the placing plate 208 is rotated around the connection position between it and the fixing frame 102, so that the inclination angle of the placing plate 208 can be adjusted. When the placing plate 208 is rotated to the maximum angle, the two second hydraulic cylinders 307 can work to push the blocking plate 301 to rotate on the outer wall of one side of the placing plate 208, so that the clamping plate 305 can continue to drive the prefabricated plate to rotate, and then the prefabricated plate can be further flipped, so that the flipping of the prefabricated plate is more convenient, and the situation that the prefabricated plate directly falls due to the rotation of the placing plate 208 can be avoided, and damage to the prefabricated plate can be avoided. The safety of the working environment can be ensured. This embodiment specifically solves the problem of falling and damage of the prefabricated plate during the flipping process in the prior art.

[0048] Refer to Figure 6 , Figure 7A concave groove 41 is provided in the middle of the placement plate 208, and a connecting hole 42 for connecting to an external air pressure mechanism is provided in the concave groove 41. A mounting ring 43 is provided at the concave groove 41, and an elastic diaphragm 44 is provided on the mounting ring 43. The upper end surface of the elastic diaphragm 44 is convex upward in an arc shape and protrudes from the upper surface of the placement plate 208. The convex height L of the elastic diaphragm 44 is 10 to 20 mm, and preferably 12 mm. In this way, a flexible buffer support can be provided when the prefabricated board is placed, and the damage of the prefabricated board can be prevented. Moreover, the setting of the elastic performance of the elastic diaphragm 44 can ensure that when the prefabricated board is placed, the elastic diaphragm 44 is pressed and sinks into the concave groove 41. When the elastic diaphragm 44 is compressed, the elastic diaphragm 44 is concave downward into an arc shape and sinks into the concave groove 41, and the depth P of the sinking is 2 to 8 mm, preferably, it can be 5 mm, and the upper end surface of the elastic diaphragm 44 is lower than the upper end surface of the placement plate 208, and the difference Q is 0.1 to 1 mm, preferably, it can be 0.5 mm. In this solution, the thickness H of the elastic diaphragm 44 should be less than the depth D of the mounting ring 43, wherein the elastic diaphragm 44 and the placement plate 208 area on the outer peripheral side of the mounting ring 43 have a smooth transition. This difference can be conducive to cleaning and also ensure the flatness and close fit between the prefabricated plate and the placement plate 208. Since the prefabricated plate is in a close fit when contacting the elastic diaphragm 44, and when the elastic diaphragm 44 is compressed and sinks into the concave groove 41, a certain space will be formed, so that natural adsorption can be achieved, but this adsorption performance is relatively low. At this time, it can be connected to the external air pressure mechanism in conjunction with the connecting hole 42 to form negative pressure adsorption.

[0049] The elastic diaphragm 44 is provided with a plurality of adsorption holes 45, and the adsorption holes 45 are conical holes, the end with a smaller aperture is connected to the concave groove 41, and the end with a larger aperture is connected to the atmosphere. The setting of the adsorption holes 45 is more conducive to the effect of negative pressure adsorption, and due to the setting of the conical holes, the release of this adsorption performance can be increased. In particular, when the elastic diaphragm 44 is convex upward, the aperture of the lower end of the adsorption hole 45 is smaller, which can be set to 0.2 to 0.5 mm, or 0.5 to 1 mm, and this aperture is also conducive to cleaning; when the elastic diaphragm 44 is concave downward, the aperture of the lower end of the adsorption hole 45 will become larger, which can be set to 1 to 2 mm. This change in aperture can effectively increase the adsorption performance of the prefabricated board during negative pressure adsorption. The elastic diaphragm 44 can be a rubber sheet, a nylon sheet, etc., or an elastic support rib 46 can be clamped in the middle of the rubber sheet, such as Figure 8 As shown, the elastic supporting ridges 46 can be used to effectively maintain the convex and concave states, thereby achieving better cushioning and adsorption effects.

[0050] When cleaning is needed, dust on the elastic diaphragm 44 can be removed by backblowing using the air pressure mechanism. When the elastic diaphragm 44 is convex upward, the aperture of the lower end of the adsorption hole 45 is smaller, which effectively prevents dust from entering the concave groove 41.

[0051] In addition, when the prefabricated panel is separated from the placement panel, the negative pressure can be cancelled to achieve rapid unloading, or the air flow can be used to achieve rapid unloading of the prefabricated panel.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
