[0021] The following combination Figure 1-Figure 3 This application is described in further detail.

[0022] The present application embodiment discloses a feeding device for a structural column casting mold. Figure 1The feeding device of the structural column casting mold includes a structural column template 1, a push plate 2, a guide rail 3 and a funnel 4. A plurality of feed ports are provided on the structural column template 1 in the vertical direction. The push plates 2 correspond to the feed ports one by one. The lower end of the push plate 2 is rotatably arranged on the structural column template 1. The push plate 2 is used to open and close the corresponding feed ports on the structural column template 1. Specifically, when the push plate 2 closes the corresponding feed port, it is fixed to the structural column template 1 by a pull rod. When the push plate 2 opens the corresponding feed port, a rope is tied to the corresponding pull rod and the end of the push plate 2 away from the structural column template 1. The rope keeps the push plate 2 in an inclined state so that it will not continue to rotate under the action of gravity. In other embodiments, the setting method of the push plate 2 can also be the same as that in the related art.

[0023] Reference Figure 1 , two guide rails 3 are symmetrically arranged, and the two guide rails 3 are detachably mounted on the structural column template 1 by means of bolts, screws, rivets, etc. The two guide rails 3 are located on opposite sides of the push plate 2 on the structural column template 1, and the funnel 4 is slidably connected between the two guide rails 3 along the vertical direction. Specifically, in order to save manpower, a winch can be arranged on the guide rail 3, and the wire rope of the winch is connected to both ends of the funnel 4, so that the funnel 4 is driven by the winch to move along the guide rail 3 and fixed to the desired position. In other embodiments, the movement method of the funnel 4 can also be the same as that in the related art.

[0024] Reference Figure 1 and Figure 2 The funnel 4 has a discharge port 5 at the lower end, and the cross-section of the discharge port 5 is rectangular. The distances from the two ends of the discharge port 5 to the center line of the push plate 2 are equal; the lower end of the funnel 4 is relatively rotatably provided with two opening and closing plates 6 for opening and closing the discharge port 5, and the arrangement direction of the two opening and closing plates 6 is parallel to the plane where the structural column template 1 is located, and the hinge axis of the opening and closing plates 6 is perpendicular to the plane where the structural column template 1 is located. A rotating shaft 11 is fixedly penetrated on the opening and closing plates 6, and the rotating shaft 11 is rotatably arranged at the lower end of the funnel 4. The funnel 4 is provided with a rotating part for driving the opening and closing plates 6 to rotate toward or away from the discharge port 5.

[0025] Reference Figure 1 and Figure 2 , the length of the opening and closing plate 6 in the direction perpendicular to the plane where the structural column template 1 is located is less than the width of the push plate 2, so that after the push plate 2 is rotated to an inclined state to open the corresponding feed port, the opening and closing plate 6 can be located between the push plate 2 and the structural column template 1; the length of the discharge port 5 is less than the length of the push plate 2, so that the opening and closing plate 6 is still located between the push plate 2 and the corresponding feed port after rotating in a direction away from the discharge port 5, ensuring that the concrete falling from the discharge port 5 will not fall directly outside the push plate 2. When the push plate 2 opens the corresponding feed port, the distance from the side of the push plate 2 away from the structural column template 1 to the structural column template 1 is greater than the distance from the side of the opening and closing plate 6 away from the structural column template 1 to the structural column template 1.

[0026] When in use, the funnel 4 is filled with concrete, the opening and closing plate 6 is in a horizontal closed discharge port 5 state, the funnel 4 is moved along the guide rail 3 to the loading position of the lowest pushing plate 2, the loading position of the pushing plate 2 refers to the position above the pushing plate 2 and the discharge port 5 of the funnel 4 is close to the upper end of the corresponding feed port; the pushing plate 2 at the lowest position is opened, so that the pushing plate 2 is inclined and relatively fixed to the structural column template 1, the distance from the side of the pushing plate 2 away from the structural column template 1 to the structural column template 1 is greater than the distance from the side of the opening and closing plate 6 away from the structural column template 1 to the structural column template 1, so that the opening and closing plate 6 is in the The opening and closing plates 6 are located between the opened push plate 2 and the structural column formwork 1, and then the two opening and closing plates 6 are driven by the rotating part to rotate in the direction away from the discharge port 5, gradually opening the discharge port 5 until the opening and closing plates 6 abut against the push plate 2. Then the concrete in the funnel 4 falls on the push plate 2 and is poured into the structural column formwork 1 along the push plate 2. Since the opening and closing plates 6 block the concrete and the two sides of the ejection point of the push plate 2, they can effectively block the splashing generated when the concrete is unloaded, making it difficult for the concrete to splash outside the push plate 2, thereby avoiding accidental injuries to workers as much as possible, and helping to improve construction safety.

[0027] When the concrete in the structural column formwork 1 is poured to the bottom of the feed port at the corresponding position, the two opening and closing plates 6 are driven by the rotating part to rotate toward the direction close to the discharge port 5 to close the discharge port 5. Then, the push plate 2 at the corresponding position closes the feed port, and then the funnel 4 is moved from bottom to top to the feed position of each push plate 2 in turn. The above steps are repeated until the casting of the structural column is completed.

[0028] Reference Figure 2 In order to drive the opening and closing plate 6 to rotate, the rotating member includes a motor 16. The motor 16 corresponds to the opening and closing plate 6 one by one. The motor 16 is fixedly mounted on the funnel 4, and the rotating shaft 11 is coaxially connected with the output shaft of the corresponding motor 16. When it is necessary to drive the opening and closing plate 6 to rotate toward or away from the discharge port 5, the motor 16 is started, and the motor 16 drives the rotating shaft 11 to drive the corresponding opening and closing plate 6 to rotate, thereby helping to close or open the discharge port 5 and providing convenience for the feeding of concrete.

[0029] Reference Figure 1 and Figure 3 A mounting groove 17 is provided on the side of the opening and closing plate 6 away from the corresponding rotating shaft 11, and an extension plate 7 is slidably inserted into the mounting groove 17. The sliding direction of the extension plate 7 is perpendicular to the rotation axis of the opening and closing plate 6. Furthermore, the sliding direction of the extension plate 7 is parallel to the plane where the structural column template 1 is located. The opening and closing plate 6 is provided with an adjustment mechanism for adjusting the extension plate 7 to extend out or extend into the corresponding opening and closing plate 6.

[0030] Reference Figure 2 and Figure 3In order to facilitate the adjustment of the extension plate 7 to extend out or extend into the corresponding opening and closing plate 6, the adjustment mechanism includes a spring 8, a connecting rope 9 and a retractable assembly. The spring 8 corresponds to the extension plate 7 one by one. The spring 8 is arranged in the mounting groove 17 in the corresponding opening and closing plate 6. The spring 8 is located on the side of the corresponding extension plate 7 close to the rotating shaft 11. The extension direction of the spring 8 is parallel to the sliding direction of the corresponding extension plate 7. One end of the spring 8 is fixed on the bottom wall of the mounting groove 17, and the other end is fixed on the side of the corresponding extension plate 7 close to the rotating shaft 11. The spring 8 is used to push the corresponding extension plate 7 to slide in the direction away from the opening and closing plate 6. When the extension plate 7 is completely located in the corresponding opening and closing plate 6, the spring 8 is in a compressed state.

[0031] Reference Figure 2 and Figure 3 A connecting block 18 is fixed on the side of the extension plate 7 away from the discharge port 5, and the connecting block 18 is slidably penetrated through the side of the corresponding opening and closing plate 6 away from the discharge port 5. A strip hole 19 that slides with the connecting block 18 is opened on the side of the opening and closing plate 6 away from the discharge port 5, and the strip hole 19 is connected to the mounting groove 17. The sliding cooperation between the connecting block 18 and the strip hole 19 provides guidance for the sliding direction of the extension plate 7, and at the same time prevents the extension plate 7 from falling out of the corresponding opening and closing plate 6.

[0032] Reference Figure 2 and Figure 3 The connecting rope 9 corresponds to the extension plate 7 one by one. One end of the connecting rope 9 is fixed on the connecting block 18 of the corresponding extension plate 7, and the other end is movably arranged on the funnel 4. The connecting rope 9 is used to pull the extension plate 7 to slide toward the direction close to the opening and closing plate 6. The retractable assembly is arranged on the funnel 4, and the retractable assembly is used to reel in or unreel the connecting rope 9.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the winding or unwinding of the connecting rope 9, the winding and unwinding assembly includes a drum 10 and a transmission member. The drum 10 corresponds to the extension plate 7 one by one. The drum 10 is rotatably arranged on the outer wall of the funnel 4. The rotation axis of the drum 10 is parallel to the rotation axis of the corresponding opening and closing plate 6. The drum 10 is located above the opening and closing plate 6. The end of the connecting rope 9 away from the corresponding extension plate 7 is wound around the corresponding drum 10. The transmission member is arranged on the funnel 4. The transmission member is used to drive the drum 10 to rotate when the opening and closing plate 6 rotates. When the opening and closing plate 6 rotates in a direction away from the discharge port 5, the transmission member drives the corresponding drum 10 to rotate to unwind the connecting rope 9.

[0034] Reference Figure 2 and Figure 3In order to facilitate the corresponding reel 10 to rotate and unwind the connecting rope 9 when the opening and closing plate 6 rotates in the direction away from the discharge port 5, the transmission member includes a transmission rod 12, a first pulley 13 and a second pulley 14. The transmission rod 12 corresponds to the reel 10 one by one. The transmission rod 12 is coaxially connected to the corresponding reel 10. The first pulley 13 is fixedly sleeved on the transmission rod 12. The second pulley 14 is coaxially fixedly sleeved on the rotating shaft 11. The first pulley 13 and the second pulley 14 of the corresponding opening and closing plate 6 are connected through a belt 15. The diameter of the first pulley 13 is larger than that of the second pulley 14. diameter, so that the rotation amplitude of the second pulley 14 is greater than the rotation amplitude of the first pulley 13, and during the rotation of the opening and closing plate 6, the two extension plates 7 are not easy to interfere with each other; when the opening and closing plate 6 drives the rotating shaft 11 to rotate in the direction away from the discharge port 5, the transmission of the first pulley 13, the second pulley 14 and the belt 15 drives the reel 10 to rotate to unwind the connecting rope 9; when the opening and closing plate 6 is in the state of closing the discharge port 5, the distance from the side of the extension plate 7 away from the rotating shaft 11 to the rotating shaft 11 is smaller than the distance from the side of the opening and closing plate 6 away from the rotating shaft 11 to the rotating shaft 11, and the spring 8 is in a compressed state.

[0035] When the opening and closing plate 6 rotates in the direction away from the discharge port 5 to gradually open the discharge port 5, the transmission rod 12 and the drum 10 are driven to rotate through the transmission of the second pulley 14, the belt 15 and the first pulley 13, so that the drum 10 unwinds the connecting rope 9, and the tension of the connecting rope 9 on the extension plate 7 is reduced. The compressed spring 8 will push the corresponding extension plate 7 to slide in the direction away from the opening and closing plate 6 until the extension plate 7 abuts against the pushing plate 2. The setting of the extension plate 7 helps to expand the shielding range, further improve the anti-splashing effect, and ensure construction safety. When the opening and closing plate 6 rotates toward the direction close to the discharge port 5 to gradually close the discharge port 5, the transmission rod 12 and the drum 10 are driven to rotate through the transmission of the second pulley 14, the belt 15 and the first pulley 13, so that the drum 10 reels the connecting rope 9, and the connecting rope 9 generates a pulling force on the extension plate 7, pulling the corresponding extension plate 7 to slide in the direction close to the opening and closing plate 6, so that the spring 8 is compressed, so as to facilitate the extension plate 7 to be completely moved into the corresponding opening and closing plate 6, thereby facilitating the closing of the discharge port 5.

[0036] Reference Figure 1 and Figure 3, the length of the extension plate 7 in the direction perpendicular to the plane where the structural column template 1 is located is less than the length of the opening and closing plate 6 in the direction perpendicular to the plane where the structural column template 1 is located, and the extension plate 7 is located on the side of the corresponding opening and closing plate 6 close to the structural column template 1. Since the push plate 2 is in an inclined state when opening the corresponding feed port, after the opening and closing plate 6 is in contact with the push plate 2 on the side away from the structural column template 1, there is still a gap between the side of the opening and closing plate 6 close to the structural column template 1 and the push plate 2, and the extension plate 7 extends into the space between the opening and closing plate 6 and the push plate 2, which helps to further improve the shielding effect and ensure construction safety. At the same time, the extension plate 7 will not affect the rotation of the opening and closing plate 6.

[0037] Reference Figure 1 and Figure 3 The cross section of the extension plate 7 is triangular, and the side of the extension plate 7 away from the structural column template 1 is an inclined surface, and the distance from the inclined surface to the structural column template 1 gradually increases toward the direction close to the corresponding rotating shaft 11. The extension plate 7 is designed as a triangular plate, so that it can match the inclined state of the push plate 2 when opening the feed port, and can better cover the gap on both sides of the push plate 2 to improve the anti-splashing effect; and the end of the extension plate 7 away from the rotating shaft 11 is smaller in size and is not easy to interfere with the push plate 2 when it extends out of the corresponding opening and closing plate 6 first.

[0038] Reference Figure 2 and Figure 3 A guide ring 20 is fixed on one side of the opening and closing plate 6 away from the discharge port 5 and close to the rotating shaft 11, and on the side of the funnel 4 close to the rotating shaft 11. The connecting rope 9 between the reel 10 and the connecting block 18 slides through the two guide rings 20 on the corresponding side, which helps to guide the movement of the connecting rope 9.

[0039] The implementation principle of the feeding device of the structural column casting mold in the embodiment of the present application is as follows: when in use, the funnel 4 is filled with concrete, and the opening and closing plate 6 is in a closed discharge port 5 state, and the funnel 4 is moved along the guide rail 3 to the loading position of the lowest pushing plate 2, so that the lower end of the funnel 4 is close to the upper end of the feeding port corresponding to the lowest pushing plate 2, and then the pushing plate 2 at the lowest position is opened, so that the pushing plate 2 remains inclined and relatively fixed to the structural column template 1, and the distance from the side of the pushing plate 2 away from the structural column template 1 to the structural column template 1 is greater than the distance from the side of the opening and closing plate 6 away from the structural column template 1 to the structural column template 1, so that the opening and closing plate 6 is located between the corresponding pushing plate 2 and the structural column template 1, and then the two motors 16 are started, and the two motors 16 synchronously drive the two opening and closing plates 6 to rotate in a direction away from the discharge port 5. , gradually open the discharge port 5, and drive the transmission rod 12 and the drum 10 to rotate through the transmission of the second pulley 14, the belt 15 and the first pulley 13, so that the drum 10 unwinds the connecting rope 9, and the tension of the connecting rope 9 on the extension plate 7 is reduced. The compressed spring 8 will push the corresponding extension plate 7 to slide in the direction away from the opening and closing plate 6 until the opening and closing plate 6 abuts against the pushing plate 2, and the extension plate 7 abuts against the pushing plate 2. The concrete in the funnel 4 falls on the pushing plate 2 and is poured into the structural column formwork 1 along the pushing plate 2. Since the opening and closing plate 6 and the extension plate 7 block the two sides of the ejection point of the concrete and the pushing plate 2, the splash generated when the concrete is discharged can be effectively blocked, so that the concrete is not easy to splash outside the pushing plate 2, and the situation of accidental injury to workers can be avoided as much as possible, which helps to improve construction safety.

[0040] When the concrete in the structural column template 1 is poured to the bottom of the corresponding position of the feed port, the two motors 16 are started to drive the two opening and closing plates 6 to rotate toward the direction close to the discharge port 5, and the discharge port 5 is gradually closed. The transmission of the second pulley 14, the belt 15 and the first pulley 13 drives the transmission rod 12 and the drum 10 to rotate, so that the drum 10 reels the connecting rope 9, and the connecting rope 9 pulls the corresponding extension plate 7 to slide toward the direction close to the opening and closing plate 6 until the extension plate 7 is completely moved into the corresponding opening and closing plate 6 and the opening and closing plate 6 closes the discharge port 5. Then the push plate 2 at the corresponding position closes the feed port, and then the funnel 4 is moved from bottom to top to the loading position of each push plate 2 in turn, and the above steps are repeated to pour concrete until the pouring of the structural column is completed.

[0041] The present application also discloses a method for casting a structural column. The method for casting a structural column uses the above-mentioned feeding device for casting a structural column mold, and further includes the following steps: Step 1: Install two guide rails 3 in parallel on the structural column template 1, and the two guide rails 3 are located on both sides of the push plate 2 on the structural column template 1; Step 2: Install the funnel 4 between the two guide rails 3.

The transmission of the second pulley 14, the belt 15 and the first pulley 13 drives the transmission rod 12 and the drum 10 to rotate, so that the drum 10 reels the connecting rope 9, and the connecting rope 9 pulls the corresponding extension plate 7 to slide toward the direction close to the opening and closing plate 6 until the opening and closing plate 6 closes the discharge port 5, and then the push plate 2 at the corresponding position closes the feed port; Step 7: Move the funnel 4 to the feeding position of each push plate 2 from bottom to top, and repeat steps 4-6 to pour concrete until the pouring of the structural column is completed.
