DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] During the production of cement poles, a concrete placing machine is used to put evenly mixed concrete materials into the lower mold 120 of the cement pole, and then the upper mold 110 and the lower mold 120 are spliced ​​together. Centrifugal molding technology is used to evenly distribute the concrete on the inner wall of the mold through the centrifugal force generated by high-speed rotation, thereby forming a dense cement pole structure.

[0039] During the process of pouring concrete, the concrete placing machine generally stops for a period of time above the lower mold 120 to disperse the material at multiple points, so the poured concrete will accumulate in the lower mold 120 and be unevenly distributed. If the concrete cannot flow evenly in the mold during the centrifugal molding process, the wall of the cement pole will be too thick in some places.

[0040] Furthermore, during the centrifugal process of the cement pole mold 100 poured with concrete, the concrete near the two ends in the mold may be displaced or deformed due to the centrifugal force. Generally, a worker is required to hold a metal rod and insert it into the center of the cement pole mold 100 to ensure the centrifugal molding quality of the cement pole end.

[0041] Combine the following Figure 1 - Fig. 9 The invention discloses an automatic cement pole concrete forming device.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, a cement pole concrete automatic forming device includes a cement pole mold 100, a blocking plate 200, a discharge motor 300 and a discharge sleeve rod 400.

[0043] The cement pole mold 100 includes an upper mold 110 and a lower mold 120, and is used to provide a cavity for pouring cement poles.

[0044] The blocking plates 200 are installed at both ends of the cement pole mold 100 to prevent concrete from leaking out of the two ends of the cement pole mold 100 during the pouring process.

[0045] Specifically, both ends of the upper mold 110 and the lower mold 120 have a fixing slot 111 , and the fixing slot 111 matches the thickness and shape of the blocking plate 200 .

[0046] The discharge motor 300 is mounted on the outer surface of the blocking plate 200 .

[0047] The discharge sleeve rod 400 has a discharge block 410 , which is installed at the output end of the discharge motor 300 and is used to push the concrete to be evenly distributed in the lower mold 120 .

[0048] The discharge block 410 is arranged in the shape of an auger on the discharge sleeve rod 400 .

[0049] Specifically, when pouring concrete in the cement rod mold 100, the discharge motor 300 is started, and the discharge motor 300 drives the discharge sleeve rod 400 to rotate, and the discharge sleeve rod 400 drives the discharge block 410 arranged in the shape of a auger to rotate synchronously, thereby generating a thrust for the concrete poured in the lower mold 120, and assisting the concrete to disperse and flow in the lower mold 120. Through stirring, the bubbles and voids in the concrete can be reduced, the density of the concrete can be enhanced, and various raw materials in the concrete can be promoted to be mixed more evenly, and it helps to reduce the voids and bubbles inside the concrete and improve the density of the concrete.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment, a positioning bolt 210 is fixedly installed on the blocking plate 200 , a fixed end plate 220 is installed on the positioning bolt 210 , and a positioning hole 221 matching the positioning bolt 210 is provided on the fixed end plate 220 .

[0051] Specifically, when installing the fixed end plate 220 , the positioning hole 221 of the fixed end plate 220 is aligned with the positioning bolt 210 for installation, and a nut is screwed on the outer end of the positioning bolt 210 to fix the fixed end plate 220 on the blocking plate 200 .

[0052] In this embodiment, a locking bracket 310 is fixedly installed at one end of the discharging motor 300 adjacent to the output end, and the locking bracket 310 has a locking hole 311 at the end facing away from the discharging motor 300. A locking screw 222 is provided on the fixed end plate 220, and the locking screw 222 passes through the locking hole 311 and is locked by a nut.

[0053] Specifically, the locking screw 222 passes through the locking hole 311 to connect the nut to fix the position of the discharge motor 300, and in the process of aligning the locking hole 311 with the locking screw 222, it has the effect of correcting the placement angle of the discharge sleeve 400, ensuring that the discharge sleeve 400 is installed parallel to the axial direction of the cement pole mold 100.

[0054] In one embodiment, the cement pole concrete automatic forming device further includes a motor base 500 (see Figure 2 ), the motor base 500 includes a moving frame 510, a cylinder 520 and a bracket 530, the cylinder 520 is installed on the moving frame 510, the bracket 530 is installed on the top of the cylinder 520, and the discharging motor 300 is installed on the bracket 530.

[0055] Specifically, before pouring concrete into the lower mold 120, the upper mold 110 is separated from the lower mold 120, the plugging plate 200 is installed in the fixed slot 111, and then the fixed end plate 220 is installed on the plugging plate 200, the discharge motor 300 is installed on the bracket 530, and the cylinder 520 is started to adjust the height of the bracket 530, so that the discharge sleeve rod 400 is at a suitable height when it moves into the lower mold 120, and then the discharge motor 300 is fixedly connected to the fixed end plate 220 using a nut, so as to fix the position of the discharge sleeve rod 400 in the lower mold 120 (please refer to the installation diagram here). Figure 5 ).

[0056] For details, see Fig. 9 The bottom of the bracket 530 is rotatably mounted with a connecting screw sleeve 532, and the top of the cylinder 520 has a threaded connector that matches the thread groove of the connecting screw sleeve 532. After the lower mold 120 is poured with concrete, the cement pole mold 100 needs to be lifted and placed on a centrifuge for centrifugal molding. At this time, the bracket 530 is separated from the cylinder 520 to reduce the lifting weight.

[0057] like Figures 5 to 7 As shown, in one embodiment, the discharge sleeve rod 400 includes an outer rod sleeve 420 and an inner rod 430 (see Figure 3 ), the inner rod 430 is fixedly mounted on the output end of the discharging motor 300, and the outer rod sleeve 420 is sleeved on the inner rod 430.

[0058] In this embodiment, the outer rod sleeve 420 has a plurality of through holes 421 (see Figure 3), the through hole 421 matches the shape of the discharge block 410 and corresponds one to one, and the inner rod 430 has a transfer groove 431, and the discharge block 410 is rotatably arranged in the transfer groove 431.

[0059] In this embodiment, both ends of the discharge block 410 extend outward to form a transfer column 411 , and the transfer groove 431 has a first limiting surface 413 and a second limiting surface 415 . The first limiting surface 413 and the second limiting surface 415 are arranged opposite to each other and parallel to the axis of the transfer column 411 .

[0060] Among them, in the initial state, the discharge block 410 is in contact with the first limit surface 413, and the discharge block 410 is separated from the second limit surface 415. The outer end of the discharge block 410 extends out of the through hole 421, and the outer rod sleeve 420 drives the discharge block 410 to abut against the second limit surface 415 by rotating in a preset direction, and the outer end of the discharge block 410 is flush with the outer wall of the outer rod sleeve 420.

[0061] In this embodiment, the inner rod 430 has a first locking screw hole 433 and a second locking screw hole 435 (see Figure 4 ), the outer rod sleeve 420 has a first limiting hole 423 and a second limiting hole 425 (see Figure 3 );

[0062] In the initial state, the first locking screw hole 433 is aligned with the first limiting hole 423 , and after the discharge motor 300 rotates in a preset direction, the second locking screw hole 435 is aligned with the second limiting hole 425 .

[0063] Specifically, during the process of pouring concrete, a bolt is used to pass through the first limiting hole 423 and screw into the first locking screw hole 433, so that the relative position of the outer rod sleeve 420 and the inner rod 430 is locked, and the inner rod 430 and the through hole 421 respectively limit the two ends of the discharge block 410, so that the relative angle between the discharge block 410 and the inner rod 430 is locked, and the discharge motor 300 drives the inner rod 430 and then drives the outer rod sleeve 420 to rotate synchronously. During this process, the discharge block 410 extending out of the through hole 421 rotates synchronously with the inner rod 430 to stir the poured concrete, and the discharge block 410 arranged in a auger shape generates a driving force for the concrete to promote the concrete to move in the lower mold 120 and distribute it more evenly.

[0064] Before centrifugation, since the cement rod mold 100 needs to be centrifugally rotated, the discharge motor 300 needs to be separated from the fixed end plate 220. After the discharge motor 300 is separated from the fixed end plate 220, the outer rod sleeve 420 is rotated to align the second limit hole 425 with the second locking screw hole 435. During this process, the discharge block 410 is driven by the through hole 421 on the outer rod sleeve 420 to swing relative to the inner rod 430, and the discharge block 410 is pulled by the inner rod 430, so that the outer end of the discharge block 410 is pushed to rotate with the through hole 421 and is able to shrink into the through hole 421, that is, the outer end of the discharge block 410 changes from a state of extending out of the through hole 421 to being flush with the surface of the inner rod 430, thereby preventing the discharge block 410 from extending out of the outer rod sleeve 420 and affecting the centrifugal motion trajectory of the concrete in the cement rod mold 100.

[0065] During the centrifugal process, the outer rod sleeve 420 inserted into the cement rod mold 100 helps to expel the air in the concrete, allowing the concrete to better fill various parts of the cement rod mold 100, thereby improving the quality of the cement rod, and can also affect the flow pattern of the concrete in the cement rod mold 100, helping to evenly distribute the concrete.

[0066] For details, see Figure 2 and Figure 3 A calibration arc plate 224 is detachably mounted on the fixed end plate 220 by bolts. In the process of separating the discharge motor 300 from the fixed end plate 220, the calibration arc plate 224 is mounted on the fixed end plate 220, and the inner arc surface of the calibration arc plate 224 is matched with the outer wall shape of the outer rod sleeve 420. In the process of moving the locking frame 310 outward and separating it from the locking screw 222, the axis of the discharge sleeve rod 400 is restricted to always be located on the axis of the cement pole mold 100, that is, the discharge sleeve rod 400 is located in the center of the cavity of the formed cement pole.

[0067] like Figure 8 As shown, in this embodiment, the axial section of the outer rod sleeve 420 is convex, the end of the outer rod sleeve 420 adjacent to the discharge motor 300 is a narrow end, and the end of the outer rod sleeve 420 away from the discharge motor 300 is a thick end.

[0068] The inner wall of the narrow end of the outer rod sleeve 420 matches the diameter of the inner rod 430, the narrow end of the outer rod sleeve 420 is rotatably connected to the inner rod 430 through a bearing, and the thick end of the outer rod sleeve 420 is rotatably connected to the end of the inner rod 430 away from the discharge motor 300.

[0069] Specifically, the end of the inner rod 430 away from the discharge motor 300 has a positioning groove 437, and the inner wall of the outer rod sleeve 420 has a positioning column 427, and the positioning column 427 matches the positioning groove 437 in shape and is connected through a bearing. The positioning column 427 is inserted into the positioning groove 437 by rotation, so that the inner rod 430 supports the end of the outer rod sleeve 420.

[0070] In this embodiment, an air inlet passage 429 is installed through the thicker tube wall of the outer rod sleeve 420 adjacent to the discharge motor 300 .

[0071] Optionally, after the centrifugation of the cement pole is completed, the air inlet channel 429 is connected to a high-temperature gas source and high-temperature gas is input into the air inlet channel 429. The high-temperature gas heats the tube wall of the outer rod sleeve 420 in the outer rod sleeve 420, causing the outer rod sleeve 420 to form an effect similar to a "heating rod", thereby achieving an auxiliary heating effect on the formed cement pole.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
