[0002] Twist-shaped blocks are a type of face armor block. Multiple twist-shaped blocks are arranged in combination on the outer layer of the breakwater to reduce the impact of waves and protect the entire breakwater structure. The design of these blocks helps reduce wave damage to the breakwater and improves the stability and durability of the breakwater. By arranging these specially designed face armor blocks, the coast can be effectively protected from the effects of wave erosion.

[0003] The twisted W-shaped block is a W-shaped structure, that is, it is composed of three rods, the two end rods are parallel to each other, and the middle rod is perpendicular to the two end rods. Most twisted W-shaped blocks are cast in concrete, that is, concrete slurry is poured into the mold, and the mold is removed after the concrete solidifies to complete the production.

[0004] However, when the existing twisted king-shaped blocks are made, the concrete poured in the mold will trap some air, and the air will enter the concrete to form bubbles, which may affect the compactness and structural strength of the concrete. In order to remove these bubbles, most people will use vibration equipment to extend into the concrete, and use vibration to float and discharge the bubbles, so that the concrete can be vibrated. However, some of the floating bubbles will still remain in the upper concrete slurry, resulting in different upper and lower structural strengths of the twisted king-shaped blocks after solidification (the upper structural strength is less than the lower structure). In order to solve the above-mentioned problems, a twisted king-shaped block pressing device is now provided. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-4 This embodiment provides a twisted king-shaped block pressing device, including a mold 1 and a movable frame 2.

[0023] Specifically, Figure 1 As shown, the mold 1 is composed of two shells sealed and spliced ​​together. An injection port is opened at the upper end of the mold 1. Concrete slurry is injected into the mold 1 through the injection port. After the concrete solidifies, the two shells are removed and separated to complete the production of the main body k of the twisted king block.

[0024] Before the concrete solidifies into a main body, bubbles are mixed in the concrete slurry. After the concrete slurry is vibrated by the vibration device, the bubbles in the concrete slurry float up and are discharged, but there are still residual bubbles remaining in the upper part of the concrete slurry. In order to remove the residual bubbles in the concrete slurry, a pressure column 5 for pressing the concrete slurry is arranged above the mobile frame 2.

[0025] Specifically, the mobile frame 2 includes a support frame 21, a movable frame 22 and a universal wheel 23. The lower end of the movable frame 22 is fixedly connected with an insertion rod, and the upper end of the support frame 21 is provided with a socket. The insertion rod of the movable frame 22 is slidably inserted into the socket of the support frame 21, so that the mobile frame 2 has a telescopic function.

[0026] like Figure 2 and Figure 3 As shown, the universal wheel 23 is rotatably connected to the lower end of the support frame 21 , wherein the universal wheel 23 is provided in plurality, and the plurality of universal wheels 23 are evenly arranged in a rectangular array, so that the support frame 21 can be easily moved by the universal wheel 23 .

[0027] like Figure 2 and Figure 3 As shown, a cover plate 3 is fixedly mounted on the upper end of the movable frame 22 , and the cover plate 3 is used to cover the upper end of the mold 1 .

[0028] When in use, stretch the movable frame 22 to move upward on the upper end of the support frame 21, move the support frame 21 to make it sleeved on the outer wall of the mold 1, pull the movable frame 22 to move the movable frame 22 and the cover plate 3 downward, and cover the cover plate 3 on the top of the mold 1.

[0029] like Figure 4 As shown, a slide cylinder 4 is fixedly inserted at the upper end of the cover plate 3, and a pressure column 5 is slidably installed inside the slide cylinder 4. The pressure column 5 slides downward and extends out from the bottom of the cover plate 3. When the cover plate 3 is covered on the mold 1, the pressure column 5 extending from the bottom of the cover plate 3 can press the upper end of the concrete slurry in the mold 1 to squeeze out the bubbles remaining in the concrete slurry.

[0030] The reciprocating sliding pressure column 5 repeatedly contacts with the pressing mold 1, which can increase the amount of bubbles discharged. The pressure column 5 located in the slide 4 is not convenient for the operator to control, so the upper end of the cover plate 3 is rotatably mounted with a control frame 6.

[0031] Specifically, a first connecting rod 61 is provided between the pressure column 5 and the control frame 6. Figure 4 As shown, one end of the first connecting rod 61 is rotatably connected to the upper end of the pressure column 5 , and the other end of the first connecting rod 61 is rotatably connected to one end of the control frame 6 .

[0032] When in use, according to the lever principle, the end of the control frame 6 away from the first connecting rod 61 is the input rod, the end close to the first connecting rod 61 is the output end, and the rotation connection between the control frame 6 and the cover plate 3 is set as a fulcrum. The end of the control frame 6 away from the first connecting rod 61 is pressed down reciprocatingly, and the pressure column 5 can be driven to slide reciprocatingly in the slide cylinder 4.

[0033] If only one part of the upper end of the concrete slurry is pressed, the amount of bubbles discharged is still insufficient. In order to press multiple upper ends of the concrete slurry, the movement of the movable frame 2 can be controlled to drive the pressure column 5 to press multiple positions of the concrete slurry. However, the movement of the movable frame 2 will drive the cover plate 3 to wear the upper end of the mold 1. In order to facilitate the control of the movement of the movable frame 22, the outer wall of the movable frame 22 is rotatably connected to the pressure frame 7.

[0034] Specifically, a second connecting rod 71 is provided between the movable frame 22 and the pressing frame 7. Figure 2 and Figure 3 As shown, one end of the second connecting rod 71 is rotatably connected to the outer side wall of the movable frame 22 , and the other end of the second connecting rod 71 is rotatably connected to the outer side wall of the pressing frame 7 .

[0035] When in use, according to the principle of lever, the end of the pressing frame 7 away from the movable frame 22 is the input rod, and the end rotatably connected to the movable frame 22 is the output rod, and the rotatably connected part of the second connecting rod 71 and the pressing frame 7 is set as a fulcrum. Pressing down the end of the pressing frame 7 away from the movable frame 22 can drive the movable frame 22 to move upward on the upper end of the supporting frame 21. The upward movement of the movable frame 22 drives the cover plate 3 to move upward, and then when the movable frame 2 moves to be sleeved on the outer wall of the mold 1, the cover plate 3 will not contact the mold 1.

[0036] When the pressure column 5 is pressed into the concrete slurry, if it is pressed too deeply into the concrete slurry, external air will be driven into the concrete slurry. In order to control the depth of the pressure column 5 pressing the concrete slurry, the two sides of the pressure column 5 are fixedly connected to the limit blocks 51.

[0037] Specifically, Figure 4 As shown, a slide groove is provided on the inner wall of the slide cylinder 4, and a limit block 51 is slidably installed in the slide groove. The movement of the pressure column 5 is limited by sliding of the limit block 51 in the slide groove, so that the depth of the concrete slurry pressed by the pressure column 5 can be controlled.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
