Description

Technical Field

[0001] The utility model relates to the technical field of slope protection brick production, in particular to a slope protection brick turning device. Background Art

[0002] At present, slope protection bricks are mainly hexagonal slope protection bricks. As the representative of ecological grass bricks, hexagonal slope protection bricks are widely used in slope protection projects. Hexagonal slope protection bricks are combined with vegetation on the slope surface to form a vegetation protection layer to prevent soil erosion and slope collapse, and realize the protection of the project. The journal "Jiangxi Highway Science and Technology" No. 4, 2007, expounded the use of hexagonal slope protection brick technology for slope protection of the sand filling section of Lewen Expressway. Manufacturers use plastic regular hexagonal molds to produce slope protection bricks, pour concrete into the mold and cure and solidify it. After the slope protection bricks are formed, in order to facilitate the subsequent demoulding operation, the slope protection bricks transported on the production line need to be turned over. To this end, the formed slope protection bricks can be erected along the length direction using a hoist or manually, and then turned over. This operation method is labor-intensive and has low work efficiency.

[0003] Patent document CN209777575U in the prior art discloses a mechanism for automatically flipping goods by 180°. The mechanism is arranged between the first conveyor line and the second conveyor line. The structure includes a flip frame, which has a receiving cavity for accommodating goods. The upper and lower parts of the receiving cavity are respectively provided with an upper conveying roller and a lower conveying roller. The flip drive assembly drives the flip frame to rotate 180° to realize a 180° flip of the goods in the receiving cavity, which improves the flipping operation efficiency to a certain extent. However, there are some problems with the flipping mechanism: the distance between the upper conveying roller and the lower conveying roller of the receiving cavity cannot be adjusted. Since the slope protection bricks themselves are relatively heavy, when the slope protection bricks enter the receiving cavity and flip, they fall and slide out due to the lack of clamping. This situation not only increases the safety risk during the flipping process of the slope protection bricks, but also the slope protection bricks directly collide with the conveying rollers, thereby causing damage to the slope protection bricks and increasing the defective rate. Therefore, this design cannot be directly applied to the flipping of the slope protection bricks. For this reason, there is still room for improvement in the current flipping mechanism. Summary of the invention

[0004] In order to solve the problems pointed out in the background technology, the utility model proposes a slope protection brick turning device.

[0029] Please refer again Figure 3 The guide assembly includes a sleeve 10 and a guide shaft 11 inserted into the sleeve 10. The sleeve 10 is arranged on the first bracket 302. Both ends of the guide shaft 11 are installed on the annular seat 201. During the extension or retraction of the telescopic rod of the cylinder 5, the guide shaft 11 is supported and guided by the sleeve 10, so that the operation of the cylinder 5 is smoother. A reinforcing rib 12 is arranged between the sleeve 10 and the first bracket 302, thereby strengthening the connection strength between the sleeve 10 and the first bracket 302.

[0030] Specifically, the protection assembly includes two guard bars 13 arranged in parallel and spaced apart, and the two ends of the guard bars 13 are respectively connected to a flat support plate 14, and the support plate 14 is provided with a long hole, and a second bolt 15 is passed through the long hole, and the second bolt 15 is connected to the first bracket 302 or the second bracket 401.

[0031] Please refer again Figure 4 The four support components are arranged on the base 1 in a rectangular shape. The support components include a bearing seat 16 and a roller 17 rotatably arranged on the bearing seat 16. The roller 17 rolls in cooperation with the circular ring seat 201. An annular protrusion 18 is arranged on one side of the roller 17. The circular ring seat 201 is limited by the protrusion 18 to prevent the circular ring seat 201 from moving left and right during rotation. The four rollers 17 support the rotating bracket 2 so that the rotating bracket 2 rotates smoothly.

When the driven sprocket 20 rotates, the driving shaft 19 drives the transmission sprocket 25 and the transmission chain 24 to rotate, thereby driving the annular seat 201 to rotate, thereby realizing the flipping of the slope protection bricks.

[0034] The usage of this product is as follows:

[0035] After the slope protection bricks transported on the production line arrive at the workstation of the flipping device, they are first received and transported by the lower conveying unit. The specific working process of the lower conveying unit is: the belt conveyor 3 is running, and when the slope protection bricks are between the belt conveyor 3 and the roller conveyor 4, the cylinder 5 extends, pushing the belt conveyor 3 to move in the direction close to the roller conveyor 4, clamping the slope protection bricks between the two, and preventing the slope protection bricks from falling and sliding out during flipping. Then, the drive motor 21 is started, driving the active sprocket 22, the drive chain 23 and the driven sprocket 20 to rotate. In this process, the transmission chain 24 is driven to rotate through the transmission sprocket 25, pushing the annular seat 201 to rotate 180° forward, thereby realizing the operation of flipping the mold with the opening upward to the state with the opening downward. At this time, the positions of the upper conveying unit and the lower conveying unit after flipping are interchanged, that is, the lower conveying unit is placed in the upper part and the upper conveying unit is placed in the lower part. Then the cylinder 5 returns to its position, and the belt conveyor 3 moves in the direction away from the roller conveyor 4, releasing the slope protection bricks clamped between the two. Subsequently, the roller conveyor 4 starts to run, driving the slope protection bricks to be sent out between the belt conveyor 3 and the roller conveyor 4, and transferred to the downstream of the production line.

[0036] Next, the upper conveying unit placed at the bottom is operated. During the operation of the upper conveying unit, the annular seat 201 rotates 180° in the opposite direction, and the positions of the upper conveying unit and the lower conveying unit are interchanged again, and then the above steps are repeated to enter the next working cycle to achieve continuous slope protection brick turning operation.

[0037] The key improvement of the utility model is that: through the provided cylinder 5, on the one hand, during the flipping process, the cylinder 5 pushes the belt conveyor 3 to move in the direction close to the roller conveyor 4, thereby clamping the slope protection bricks; on the other hand, after the flipping is completed, the cylinder 5 pushes the belt conveyor 3 to move in the direction away from the roller conveyor 4, thereby releasing the slope protection bricks clamped therebetween. Through the above-mentioned arrangement, the slope protection bricks are prevented from falling and sliding out during flipping, thereby causing damage due to collisions.

[0038] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
