TECHNICAL FIELD

[0001] The present application relates to the technical field of slope protection, in particular to a twisted king block production device and method. BACKGROUND

[0002] The twisted king block is a kind of facing block, which is generally placed in the outermost layer of the breakwater to protect the breakwater by weakening the impact force of the wave. The twisted king block belongs to a relatively complex component in the concrete prefabricated component, which is composed of three rods, the two end rods are parallel, and the middle rod is orthogonal to the two end rods. The material is concrete, which is poured by a fixed mold at one time. The twisted king block is widely used in marine wharf projects and other projects, and the production quantity is large. In the prefabrication and pouring process of the twisted king block, a series of processes such as mold erection, concrete pouring, curing, mold removal, and secondary curing are required. The production links are more, the production efficiency is low, the production area is large, and it is difficult to avoid confusion in manual operation, which affects the overall construction progress. In addition, the vibration and compaction of the produced twisted king block is poor, which easily leads to poor quality of the produced twisted king block. SUMMARY

[0003] The present application provides a twisted king block production device and method to solve the problem that the existing production device has more production links, which easily affects the construction progress, and the produced twisted king block has poor compaction.

[0004] In a first aspect, the present application provides a twisted king block production device, comprising: a rack; a centrifugal disc, which is rotationally arranged on the rack; a mold, which is arranged on the centrifugal disc and is adapted to rotate with the centrifugal disc, and the mold is provided with a feeding port; a hopper, the discharge end of which is correspondingly arranged with the feeding port of the mold.

[0005] Advantages: The discharge end of the hopper corresponds to the feeding end of the mold, so that the material can continuously and stably enter the mold, and the centrifugal force can drive the material to quickly fill the corners, gaps and other areas that are difficult to fill by traditional gravity filling, effectively overcoming the defects of uneven material accumulation, local hollows, and non-dense edge filling in the traditional filling method. The material is uniformly filled into the mold by the centrifugal force, which not only improves the density of the twist king block, but also makes the internal structure of the twist king block more uniform and stable, thereby enhancing the structural strength of the twist king block. Compared with the prior art, the present application can reduce the number of workstations and the area occupied by the site during production, eliminate the vibration workstation and independent formwork workstation in traditional production, and the mold setting can be directly completed on the centrifugal disc, and the material can be compacted simultaneously during the centrifugal filling process. Not only simplifies the production process, but also avoids the time loss caused by material transfer and process switching, and shortens the production cycle of a single batch of twist king blocks.

[0006] In an alternative embodiment, further comprising: The adjustable fixing device has a fixed state of fixing the mold to the centrifugal disc, and an unlocked state of disconnecting the mold from the centrifugal disc.

[0007] Advantages: The adjustable fixing device can fix the mold on the centrifugal disc, avoiding the mold from shaking or deviating under the action of centrifugal force, thereby causing uneven internal structure of the twist king block. At the same time, the adjustable fixing device can adapt to molds of different sizes by adjusting the clamping range or the stroke of the top bar. When the adjustable device is in the unlocked state, the mold can be disconnected from the centrifugal disc, facilitating the quick transfer of the mold after material injection to the curing area, thereby indirectly improving the turnover rate of the mold.

[0008] In an alternative embodiment, further comprising a protective ring, the protective ring being arranged on the centrifugal disc, the protective ring being enclosed to form a containing cavity, the containing cavity being used for at least partially containing the mold.

[0009] Advantages: The containing cavity formed by the protective ring can limit the mold, avoiding the risk of outward sliding, dumping or even flying out of the mold when the centrifugal disc drives the mold to rotate, thereby improving the safety during production. At the same time, the containing cavity can limit the radial shaking amplitude of the mold, avoiding the quality problems of twist king block such as size deviation and uneven internal structure caused by excessive shaking of the mold.

[0010] In an alternative embodiment, the adjustable fixing device comprises a pressing device movably arranged on the protective ring, and the pressing device is adapted to press the mold.

[0011] Advantages: The pressing device is movably arranged on the protective ring, and the protective ring is used as a force support. By adjusting the tightness of the pressing device, different specifications of the mold can be adapted. For the mold with large size or heavy weight, the pressing device can be adjusted to a tighter state to increase the pressing force to adapt to larger centrifugal force, so as to ensure that the mold does not deviate or shake during rotation. For the mold with small size or thin wall thickness, the pressing device can be appropriately loosened to avoid deformation of the mold due to excessive pressing force and to protect the integrity of the mold.

[0012] In an alternative embodiment, the adjustable fixing device comprises a pressing device movably arranged on the protective ring, and the pressing device is adapted to press the mold. The driving member; The transmission device is connected between the driving member and the rotating shaft of the centrifugal disc.

[0013] Advantages: The output power of the driving member can be adjusted to adjust the rotating speed of the centrifugal disc, and the centrifugal force of different molds can be adapted.

[0014] In an alternative embodiment, the pressing device is arranged along the circumference of the protective ring.

[0015] Advantages: The multiple pressing devices arranged along the axial direction of the protective ring can apply force to the mold from multiple directions of the protective ring, avoiding excessive local force on the mold due to single-point or single-side pressing. At the same time, the load can be dispersed, the mold can be fixed from multiple directions, the risk of mold slipping or flying out can be reduced, and the safety of the production process can be further ensured.

[0016] In an alternative embodiment, multiple adjusting holes are arranged on the protective ring to adapt to different positions of the pressing device.

[0017] Advantages: The multiple adjusting holes arranged on the protective ring provide multiple mounting points for the pressing device, so that the twist king block can adapt to different specifications of the mold, thereby producing twist king blocks of different specifications.

[0018] In an alternative embodiment, the hopper is arranged on the mold.

[0019] Advantages: The hopper is positioned above the mold, allowing for adjustment of the distance between the hopper's outlet and the mold's inlet based on the mold's height, inlet location, and material filling progress. This ensures optimal alignment between the two. For taller molds, the hopper can be raised to prevent collisions and interference; for shorter molds, the hopper can be lowered to shorten the material's descent distance, reducing splashing and dust during the fall, minimizing raw material loss, and preventing splashed material from contaminating the mold's outer wall or the production environment.

[0020] In one alternative embodiment, a connecting pipe is also included, which is detachably disposed between the feed inlet of the mold and the discharge end of the hopper.

[0021] Beneficial effects: Different lengths of connecting pipes can be used to adapt to different heights of torsion blocks, thus accommodating the production of different torsion blocks. At the same time, the connecting pipes can seal the discharge end of the hopper and the feed inlet of the mold, reducing material spillage during the falling process, reducing raw material loss, and preventing splashed material from polluting the production environment and increasing the amount of subsequent cleaning work.

[0022] Secondly, the present invention also provides a method for producing torsion blocks, applied to the torsion block production apparatus as described above, the method comprising: Place the cleaned and oiled mold in the center of the centrifuge tray; Use a clamping device to clamp the mold; Align the discharge end of the hopper with the inlet of the mold; Material is poured into the hopper so that it enters the inner cavity of the mold through the hopper. At the same time, the drive unit drives the transmission device to rotate, so that the centrifugal disc drives the mold to rotate. After the injection is completed, loosen the clamping device and transfer the mold to the curing area for curing. Demolding the mold yields the twisted block. Attached Figure Description

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The twisted king block is a kind of armor block, which is generally placed in the outermost layer of the breakwater to protect the breakwater by weakening the impact force of the waves. The twisted king block belongs to a relatively complex component in the concrete prefabricated component, which is composed of three bars, the two end bars are parallel, and the middle bar is orthogonal to the two end bars. The material is concrete, which is completed by one-time pouring through a shaped mold 3. The twisted king block is currently used in large quantities in projects such as marine wharfs, and the production quantity is large. In the prefabrication and pouring process of the twisted king block, a series of processes such as mold erection, pouring of concrete, curing, mold removal, and secondary curing are required, and there are many production links. In manual operation, it is difficult to avoid confusion, which will affect the overall construction progress, and the vibration and compaction of the produced twisted king block is poor.

[0028] In the related art, a construction site is divided into a formwork setting position, a pouring position, a vibrating zone, a curing zone and a transfer zone, each group of prefabrication positions respectively performs four steps of formwork 3 setting, concrete pouring, vibrating, concrete block curing and formwork 3 removal, each step is alternately performed, finally the twisted king block is transported to the curing zone for curing and to the transfer zone for transfer, which is suitable for large-scale production of twisted king blocks. In the specific construction operation, the above technology only designs each position according to the process sequence to produce, but the twisted king blocks produced according to the above process sequence have long curing time, low formwork 3 turnover rate, poor vibrating compaction effect and large production area.

[0029] The embodiments of the present application will be described below in conjunction with Figures 1 to 11 .

[0030] According to the embodiments of the present application, in one aspect, a twisted king block production device is provided, comprising: a rack 1; a centrifugal disc 2 rotatably arranged on the rack 1; a formwork 3 arranged on the centrifugal disc 2 and adapted to rotate with the centrifugal disc 2, the formwork 3 being provided with a feeding port; a hopper 6, the discharge end of the hopper 6 being arranged corresponding to the feeding port of the formwork 3.

[0031] As shown in Figure 1 , the feeding end of the hopper 6 is larger than the discharge end, the discharge end of the hopper 6 is opposite to the feeding port of the formwork 3, and the axis of the hopper 6 coincides with the axis of the rotating shaft 9 of the centrifugal disc 2, so that the material falling from the discharge end can vertically enter the inner cavity of the formwork 3 along the center of the feeding port of the formwork 3, and the material can uniformly spread in all directions of the inner cavity of the formwork 3 under the action of centrifugal force, ensuring the uniform distribution density of the twisted king block in the formwork 3.

[0032] It should be noted that the material in the present application is generally concrete, and in the specific material distribution, dry concrete, i.e. concrete with low slump, can be selected, so that there is no surplus slurry after centrifugation and the curing time of the twisted king block can be reduced, and the turnover frequency of the formwork 3 can be improved.

[0033] The discharge end of the hopper 6 corresponds to the feeding end of the mold 3, so as to ensure that the material can continuously and stably enter the mold 3, and the centrifugal force can drive the material to quickly fill the corners of the mold 3, including the corners, gaps and other areas that are difficult to cover by traditional gravity filling, thereby effectively overcoming the defects of uneven material accumulation, local hollow, and non-dense filling of the corners in the traditional filling method. The material is uniformly filled into the mold 3 by the centrifugal force, which not only improves the density of the twist king block, but also makes the internal structure of the twist king block more uniform and stable, thereby enhancing the structural strength of the twist king block. Compared with the existing technology, the production process of the present application can reduce the number of workstations and the area occupied by the site, and the traditional production process of the vibration workstation and the independent formwork workstation is omitted, the formwork 3 can be directly set on the centrifugal disc 2, and the centrifugal filling process can simultaneously realize the compaction of the material; not only simplifies the production process, but also avoids the time loss caused by material transfer and process switching, and shortens the production cycle of a single batch of twist king blocks.

[0036] The adjustable fixing device can fix the mold 3 on the centrifugal disc 2, so as to avoid the shaking or deviation of the mold 3 under the action of the centrifugal force, thereby causing the problem of uneven internal structure of the twist king block. At the same time, the adjustable fixing device can adapt to molds 3 of different sizes by adjusting the clamping range or the pressing stroke. In the unlocked state, the mold 3 can be disconnected from the centrifugal disc 2, so as to facilitate the quick transfer of the mold 3 after material injection to the curing area, and indirectly improve the turnover rate of the mold 3.

The height of the protective ring 4 is generally higher than half the height of the torsion block, so that the mold 3 will not come out of the protective ring 4 when rotating. Among them, the barrel-shaped protective ring 4 can be made of high-strength steel or wear-resistant alloy material, and the inner wall can be provided with wear-resistant lining plate or buffer pad; the grid-shaped protective ring 4 is composed of vertical grid bars and upper and lower annular frames uniformly distributed along the centrifugal disc 2, the grid bars can be made of high-strength steel, and the width of each grid bar is the same, and the grid gaps between adjacent grid bars are the same.

[0039] The accommodating cavity enclosed by the protective ring 4 can limit the mold 3, avoiding the risk of outward sliding, tilting or even flying out of the mold 3 when the centrifugal disc 2 drives the mold 3 to rotate, improving the safety in the production process, and the accommodating cavity can also limit the radial shaking amplitude of the mold 3, avoiding the quality problems such as size deviation and uneven internal structure of the torsion block caused by the shaking of the mold 3.
