Description

Technical Field

[0001] The invention relates to the field of construction engineering, and in particular to a concrete pouring device. Background Art

[0002] Concrete pouring devices have important applications in the field of construction engineering. They are mainly used to produce various concrete components, including but not limited to hollow pipes, columns, plates, etc. These devices ensure that the shape, size and quality of the components meet the design requirements by accurately controlling the pouring and molding process of concrete. In construction engineering, concrete components are an important part of the supporting and bearing structure. Therefore, the stability, accuracy and efficiency of the concrete pouring device directly affect the quality and progress of the project.

[0016] As a further solution of the present invention, the gear rack is meshingly connected with the transmission gear, the length of the bottom of the gear rack and the ear plate on the top side is greater than twice the vertical length of the top block, and the radius of the transmission gear is smaller than the distance between the center of the transmission gear and the edge of the fixed cover.

[0017] The beneficial effects of the present invention are as follows:

[0018] By setting up the demoulding structure, when the hollow concrete tube is formed, the pinion rotates, driving the tooth plate to rotate, and then driving the demoulding structure to operate, so that the four outer barrel plates expand and slide outward, and the four inner barrel plates shrink and slide inward, so that there is no large area of ​​adhesion of the device on the outside and inside of the hollow concrete tube, so that the hollow concrete tube is easy to demould after forming, and the demoulding efficiency of the equipment is improved, and then the concrete pouring efficiency of the equipment is indirectly improved. In addition, since the hollow concrete tube and the equipment are no longer adhered at this time, it is also avoided that the hollow concrete tube is broken during the removal process, which increases the use cost of the concrete pouring device and greatly reduces its molding quality;

[0019] By setting a fixed cover to cooperate with a plurality of pins, after pouring concrete into the cavity, each pin is aligned with each slot and inserted, so that the fixed cover is embedded in the top plate, so that the top of the cavity is closed, and the fixed cover squeezes the unsolidified concrete so that the concrete can solidify into a complete concrete hollow pipe, and after the plurality of pins are respectively plugged into the plurality of slots, the tops of the four outer barrel plates and the four inner barrel plates are all in a fixed state, so as to avoid the shaking of the outer barrel plates and the inner barrel plates during the concrete solidification process, thereby ensuring the molding quality of the concrete hollow pipe;

[0020] By setting a fixed release structure, the transmission shaft rotates to drive the elliptical cylinder to rotate. During the rotation of the elliptical cylinder, the top block is gradually squeezed, so that the top block slides toward the center of the top plate at the top of the top plate. Since the other side of the top block is set as an inclined surface, and one side of the lifting block is also set as an inclined surface, therefore, during the sliding process of the top block, the lifting block is pressed against and slides upward. When the top of the top block contacts the bottom of the lifting block, the elliptical cylinder is no longer in contact with the top block. At this time, the bottom position of the latch is flush with the top position of the top plate. At this time, the latch is completely separated from the slot, so that the top of the outer barrel plate and the top of the inner barrel plate are no longer fixed. Therefore, its demoulding structure can operate. During the sliding process of the top block, the two sliding rods are driven to move together with the two limit blocks, so that the two springs are compressed.

[0021] By setting the residual gear to cooperate with the power gear, the residual gear is not meshed with the pinion gear when it is in the initial state. Therefore, when the starting motor drives the residual gear to rotate, the power gear is driven to rotate through the rotating shaft, and then the transmission shaft on one side is driven through the tooth block on one side, and then the fixing release structure on one side is driven to operate. The tooth block on one side drives the transmission shaft on one side to rotate, which will drive the gear ring to rotate, and then drive the tooth block on the other side together with the transmission shaft on the other side to rotate, and then drive the fixing release structure on the other side. Therefore, the fixed cover is lifted up, and the tops of the four outer barrel plates and the four inner barrel plates are released. At this time, the residual gear begins to mesh with the pinion gear, thereby driving the demoulding structure to operate, and realizing the demoulding of the concrete hollow pipe;

[0022] By setting a power transmission structure, when the fixed cover is completely lifted up by the two fixing release structures, the bottom position of the latch is flush with the top of the top plate, and in the process of lifting the fixed cover, the connecting plate is driven to move up along the rotating shaft. When the fixed cover is completely lifted up, the transmission groove is engaged with the transmission block, and then the motor drives the residual gear to rotate, and in the process of driving the rotating shaft to rotate, the gear frame is driven to rotate, and then the transmission gear is driven to rotate, thus driving the rotating shaft to rotate, thereby driving the connecting plate and the fixed cover to rotate together. When the outer barrel plate is expanded to the maximum state and the inner barrel plate is in the minimum contraction state, the fixed cover no longer blocks the top of the cavity, so that the formed concrete hollow pipe can be taken out from the top of the cavity, avoiding the situation that the fixed cover blocks the top of the cavity and the concrete hollow pipe cannot be taken out from the top of the cavity;

[0023] Since only one motor is needed to drive the fixed release structure, demoulding structure and power transmission structure to operate in sequence, the power input end of the equipment is reduced. Only one power input end is needed to complete a series of processes, which not only makes the linkage between different structures of the equipment stronger, but also makes the work coordination between different structures stronger. In addition, no human intervention is required in this process, which reduces the need for manual intervention in the pouring and demoulding processes and improves production efficiency and safety.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1 - Fig.11 As shown, a concrete pouring device comprises a fixing frame 1, a top plate 2 is fixedly installed on the top of the fixing frame 1, a bottom plate 3 is fixedly installed on the bottom of the fixing frame 1, two ear plates 7 are symmetrically installed on the outer surfaces of the top plate 2 and the bottom plate 3, four outer barrel plates 10 are slidably connected between the top plate 2 and the bottom plate 3 and located inside the fixing frame 1, four inner barrel plates 11 are slidably connected between the top plate 2 and the inside of the four outer barrel plates 10, four fixed arc plates 12 are fixedly installed between the top plate 2 and the bottom plate 3 and through the bottom of the outer barrel plates 10, and a demoulding structure 4 is arranged inside the fixing frame 1;

[0038] The demoulding structure 4 includes a tooth plate 15, which is rotatably mounted on the bottom of the bottom plate 3. The top of the bottom plate 3 penetrates the bottom and is provided with four slide grooves 14 near the center of the circle. The top of the tooth plate 15 penetrates the bottom and is provided with four arc grooves 19 near the center of the circle. The top of the bottom plate 3 penetrates the bottom and is provided with four slide grooves 2 43 away from the center of the circle. The top of the tooth plate 15 penetrates the bottom and is provided with four arc grooves 2 41 away from the center of the circle. The insides of the four outer barrel plates 10 penetrate the bottom and are provided with four through grooves 16 in common. The bottoms of the four inner barrel plates 11 penetrate the four through grooves 16, the four slide grooves 14 and the four arc grooves 19 respectively, and the connecting rods 12 are fixedly mounted thereon. The bottoms of the four outer barrel plates 10 penetrate the four slide grooves 2 43 and the four arc grooves 2 41 respectively, and the connecting rods 2 17 are fixedly mounted thereon. A pinion 18 is rotatably mounted on the bottom of the ear plate 7 on the bottom side.

[0039] In this embodiment, the pinion 18 is meshed with the tooth plate 15, the four outer barrel plates 10 are cylindrical as a whole, the four inner barrel plates 11 and the four fixed arc plates 12 are cylindrical as a whole, and when the four outer barrel plates 10 and the four inner barrel plates 11 are in the initial state, there is a cavity between the inner walls of the four outer barrel plates 10 and the outer walls of the four fixed arc plates 12 and the four inner barrel plates 11, and concrete is poured into the cavity. After the concrete solidifies, the concrete can be formed into a concrete hollow tube;

[0040] After the concrete solidifies, the pinion 18 rotates, driving the tooth plate 15 to rotate, and the tooth plate 15 rotates, driving the four arc grooves 19 and the four arc grooves 2 41 to rotate, thereby forcing the four connecting rods 1 42 and the four connecting rods 2 17 to slide along the four slide grooves 14 and the four slide grooves 2 43 respectively. Since one end of the four connecting rods 1 42 is located inside the arc groove 19 and close to the center of the tooth plate 15, and one end of the connecting rod 2 17 is located inside the arc groove 2 41 and away from the center of the tooth plate 15, the connecting rods The connecting rod 142 slides along the slide groove 14 and toward the center of the tooth plate 15, and the connecting rod 17 slides along the slide groove 43 and away from the center of the tooth plate 15. Therefore, the four outer barrel plates 10 expand and slide toward the outer circle of the bottom plate 3, and the four inner barrel plates 11 shrink and slide toward the center of the bottom plate 3, so that the outer surface of the solidified concrete hollow tube no longer contacts the outer barrel plates 10, so that the concrete hollow tube is easy to demould, thereby improving the demoulding efficiency of the concrete hollow tube.

[0041] In this embodiment, one end of the connecting rod 1 42 is located inside the arc groove 19 and close to the center of the tooth plate 15 , and one end of the connecting rod 2 17 is located inside the arc groove 2 41 and away from the center of the tooth plate 15 .

[0042] In this embodiment, a fixed cover 8 is embedded inside the top plate 2, two slots 13 are provided on the top of the outer barrel plate 10 and the inner barrel plate 11, and eight pairs of latches 9 are fixedly installed on the bottom of the fixed cover 8, and the position of each latch 9 corresponds to the position of each slot 13, and the latches 9 are adaptively matched with the slots 13;

[0043] After pouring concrete into the cavity, align each pin 9 with each slot 13 and insert it, so that the fixing cover 8 is embedded in the top plate 2, so that the top of the cavity is closed, and the fixing cover 8 will squeeze the unsolidified concrete so that the concrete can solidify into a complete concrete hollow tube. After multiple pins 9 are respectively plugged into multiple slots 13, the tops of the four outer barrel plates 10 and the four inner barrel plates 11 are all in a fixed state, thereby avoiding the shaking of the outer barrel plates 10 and the inner barrel plates 11 during the concrete solidification process, thereby ensuring the molding quality of the concrete hollow tube.

[0044] In this embodiment, the top plate 2 is symmetrically provided with two fixing release structures 5, which include a lifting block 22 and a lifting block 23. The lifting block 22 is fixedly installed on one side of the top of the fixed cover 8, and the lifting block 23 is slidably connected to the top of the top plate 2 and is located on one side of the lifting block 22. Two fixing blocks 24 are symmetrically fixedly installed on the top of the ear plate 7 on the top side. A sliding rod 25 is fixedly installed on the front and rear of one side of the lifting block 23. One end of the sliding rod 25 passes through one side of the fixing block 24 and is fixedly installed with a limiting block 26. A spring 27 is fixedly connected between the limiting block 26 and the fixing block 24 and on the outer surface of the sliding rod 25. A transmission shaft 21 is rotatably connected between the two ear plates 7 symmetrically up and down on one side. An elliptical cylinder 20 is rotatably installed on the top of the ear plate 7 on the top side. The top of the transmission shaft 21 passes through the ear plate 7 on the top side and is fixedly connected to the bottom of the elliptical cylinder 20.

[0045] The rotation of the transmission shaft 21 drives the elliptical cylinder 20 to rotate. During the rotation of the elliptical cylinder 20, the top block 23 will be gradually squeezed, so that the top block 23 slides toward the center of the top plate 2 at the top of the top plate 2. Since the other side of the top block 23 is arranged in an inclined surface, and one side of the lifting block 22 is also arranged in an inclined surface, therefore, during the sliding process of the top block 23, the lifting block 22 is pressed against, so that the lifting block 22 slides upward. When the top of the top block 23 contacts the bottom of the lifting block 22, the elliptical cylinder 20 is no longer in contact with the top block 23. At this time, the bottom position of the latch 9 is flush with the top position of the top plate 2. At this time, the latch 9 is completely separated from the slot 13, so that the top of the outer barrel plate 10 and the top of the inner barrel plate 11 are no longer fixed. Therefore, its demolding structure 4 can operate. During the sliding process of the top block 23, the two sliding rods 25 are driven to move together with the two limit blocks 26, so that the two springs 27 are compressed.

[0046] In this embodiment, the short axis arc edge of the elliptical cylinder 20 contacts one side of the top block 23, the other side of the top block 23 is set as an inclined surface, and one side of the lifting block 22 is also set as an inclined surface, and the inclination angle of the other side of the top block 23 is complementary to the inclination angle of one side of the lifting block 22.

[0047] In this embodiment, the vertical lengths of the lifting block 22 and the lifting block 23 are consistent, and the vertical length of the lifting block 22 is consistent with the vertical length of the fixing cover 8 and the latch 9 as a whole.

[0048] In this embodiment, a rotating shaft 28 is rotatably installed on one side between two ear plates 7 symmetrically arranged on one side, a power gear 29 is fixedly connected to the outer surface of the rotating shaft 28 between the two ear plates symmetrically arranged on one side, a tooth block 30 is fixedly connected to the outer surface of the transmission shaft 21, a gear ring 31 is rotatably connected to the outer surface of the fixed frame 1, a residual gear 32 is rotatably connected to the bottom of the ear plate 7 on the bottom side, the residual gear 32 is meshed with the pinion 18, the power gear 29 is meshed with the tooth block 30, the tooth block 30 is meshed with the gear ring 31, a mounting frame 33 is fixedly installed at the bottom of the ear plate 7 on the bottom side at the bottom of the residual gear 32, a motor 34 is fixedly installed at the bottom of the mounting frame 33, and an output shaft of the motor 34 passes through the top of the mounting frame 33 and is fixedly connected to the residual gear 32;

[0049] When the residual gear 32 is in the initial state, it is not meshed with the pinion 18. Therefore, when the starting motor 34 drives the residual gear 32 to rotate, the power gear 29 is driven to rotate through the rotating shaft 28, and then the transmission shaft 21 on one side is driven through the tooth block 30 on one side, and then the fixing release structure 5 on one side is driven to operate. The tooth block 30 on one side drives the transmission shaft 21 on one side to rotate, which will drive the gear ring 31 to rotate, and then drive the tooth block 30 on the other side together with the transmission shaft 21 on the other side to rotate, and then drive the fixing release structure 5 on the other side. Therefore, the fixing cover 8 is lifted up, and the tops of the four outer barrel plates 10 and the four inner barrel plates 11 are released. At this time, the residual gear 32 begins to mesh with the pinion 18, thereby driving the demoulding structure 4 to operate, and realizing the demoulding of the concrete hollow pipe.

[0050] In this embodiment, a power transmission structure 6 is provided on the top of the top plate 2, and the power transmission structure 6 includes a transmission block 38 and a transmission groove 40. The top of the top plate 2 is connected to a rotating shaft 37 for rotation away from the center of the circle, and a transmission gear 36 is fixedly installed on the top of the rotating shaft 37. The top of the rotating shaft 28 passes through the top of the ear plate 7 on the top side and is fixedly connected to the gear rack 35. The transmission block 38 is fixedly installed on the outer surface of the rotating shaft 37. A connecting plate 39 is provided on the outer surface of the rotating shaft 37. The connecting plate 39 is fixedly connected to the top of the fixed cover 8. The transmission groove 40 passes through one end of the connecting plate 39, and the transmission groove 40 is adaptively matched with the transmission block 38.

[0051] When the fixing cover 8 is fully lifted up, the bottom position of the latch 9 is flush with the top of the top plate 2, and the connecting plate 39 is driven to move upward along the rotating shaft 37 during the lifting of the fixing cover 8. When the fixing cover 8 is fully lifted up, the transmission groove 40 is engaged with the transmission block 38, and then the motor 34 drives the residual gear 32 to rotate, and in the process of driving the rotating shaft 28 to rotate, the gear frame 35 is driven to rotate, and then the transmission gear 36 is driven to rotate, thereby driving the rotating shaft 37 to rotate, thereby driving the connecting plate 39 to rotate together with the fixing cover 8. During the rotation of the fixing cover 8, the latch 9 will contact the top of the top plate 2, so that during the rotation of the fixing cover 8, even if the top block 23 is no longer in contact with the lifting block 22, the fixing cover 8 will not fall, thereby avoiding the separation of the transmission groove 40 and the transmission block 38, resulting in the situation that the fixing cover 8 cannot continue to rotate.

[0052] In this embodiment, the gear rack 35 is meshedly connected with the transmission gear 36, the length of the bottom of the gear rack 35 and the ear plate 7 on the top side is greater than twice the vertical length of the top block 23, and the radius of the transmission gear 36 is smaller than the distance between the center of the transmission gear 36 and the edge of the fixed cover 8.

[0053] It should be noted that the present invention is a concrete pouring device. When in use, when the four outer barrel plates 10 and the four inner barrel plates 11 are in the initial state, there is a cavity between the inner walls of the four outer barrel plates 10 and the outer walls of the four fixed arc plates 12 and the four inner barrel plates 11. Concrete is poured into the cavity, and after the concrete solidifies, the concrete can be formed into a concrete hollow tube.

[0054] After the concrete solidifies, the pinion 18 rotates, driving the tooth plate 15 to rotate, and the tooth plate 15 rotates, driving the four arc grooves 19 and the four arc grooves 2 41 to rotate, thereby forcing the four connecting rods 1 42 and the four connecting rods 2 17 to slide along the four slide grooves 14 and the four slide grooves 2 43 respectively. Since one end of the four connecting rods 1 42 is located inside the arc groove 19 and close to the center of the tooth plate 15, and one end of the connecting rod 2 17 is located inside the arc groove 2 41 and away from the center of the tooth plate 15, the connecting rods The connecting rod 142 slides along the slide groove 14 and toward the center of the tooth plate 15, and the connecting rod 17 slides along the slide groove 43 and away from the center of the tooth plate 15, so that the four outer barrel plates 10 expand and slide toward the outer circle of the bottom plate 3, and the four inner barrel plates 11 shrink and slide toward the center of the bottom plate 3, so that the outer surface of the solidified concrete hollow pipe no longer contacts the outer barrel plate 10, so that the concrete hollow pipe is easy to demould, thereby improving the demoulding efficiency of the concrete hollow pipe;

[0055] After pouring concrete into the cavity, align each pin 9 with each slot 13 and insert it, so that the fixed cover 8 is embedded in the top plate 2, so that the top of the cavity is closed. The fixed cover 8 squeezes the unsolidified concrete so that the concrete can solidify into a complete concrete hollow tube. After the multiple pins 9 are respectively plugged into the multiple slots 13, the tops of the four outer barrel plates 10 and the four inner barrel plates 11 are all in a fixed state, thereby preventing the outer barrel plates 10 and the inner barrel plates 11 from shaking during the concrete solidification process, thereby ensuring the molding quality of the concrete hollow tube;

[0056] The rotation of the transmission shaft 21 drives the elliptical cylinder 20 to rotate. During the rotation of the elliptical cylinder 20, the top block 23 will be gradually squeezed, so that the top block 23 slides toward the center of the top plate 2 at the top of the top plate 2. Since the other side of the top block 23 is arranged in an inclined surface, and one side of the lifting block 22 is also arranged in an inclined surface, therefore, during the sliding process of the top block 23, the lifting block 22 is pressed against the lifting block 22, so that the lifting block 22 slides upward. When the top of the top block 23 contacts the bottom of the lifting block 22, the elliptical cylinder 20 is no longer in contact with the top block 23. At this time, the bottom position of the latch 9 is flush with the top position of the top plate 2. At this time, the latch 9 is completely separated from the slot 13, so that the top of the outer barrel plate 10 and the top of the inner barrel plate 11 are no longer fixed. Therefore, its demoulding structure 4 can operate. During the sliding process of the top block 23, the two sliding rods 25 are driven to move together with the two limit blocks 26, so that the two springs 27 are compressed;

[0057] When the residual gear 32 is in the initial state, it is not meshed with the pinion 18. Therefore, when the starting motor 34 drives the residual gear 32 to rotate, the power gear 29 is driven to rotate through the rotating shaft 28, and then the transmission shaft 21 on one side is driven through the tooth block 30 on one side, and then the fixing release structure 5 on one side is driven to operate. The tooth block 30 on one side drives the transmission shaft 21 on one side to rotate, which will drive the gear ring 31 to rotate, and then drive the tooth block 30 on the other side together with the transmission shaft 21 on the other side to rotate, and then drive the fixing release structure 5 on the other side, so that the fixed cover 8 is lifted up, and the tops of the four outer barrel plates 10 and the four inner barrel plates 11 are released. At this time, the residual gear 32 begins to mesh with the pinion 18, thereby driving the demoulding structure 4 to operate, and realizing the demoulding of the concrete hollow pipe;

[0058] Since the vertical length of the lifting block 22 is consistent with the vertical length of the fixed cover 8 and the latch 9 as a whole, when the fixed cover 8 is completely lifted up by the two fixing release structures 5, the bottom position of the latch 9 is flush with the top of the top plate 2, and in the process of the fixed cover 8 being lifted up, the connecting plate 39 is driven to move up along the rotating shaft 37. When the fixed cover 8 is completely lifted up, the transmission groove 40 is engaged with the transmission block 38, and then the motor 34 drives the residual gear 32 to rotate, and in the process of driving the rotating shaft 28 to rotate, the gear frame 35 is driven to rotate, and then the transmission gear 36 is driven to rotate, thereby driving the rotating shaft 37 to rotate, and thus driving the connecting plate 39 to rotate together with the fixed cover 8. , since the latch 9 will contact the top of the top plate 2 during the rotation of the fixed cover 8, the fixed cover 8 will not fall even if the top block 23 is no longer in contact with the lifting block 22 during the rotation of the fixed cover 8, thereby avoiding the transmission groove 40 and the transmission block 38 from being separated, resulting in the fixed cover 8 being unable to continue to rotate. When the outer barrel plate 10 is expanded to the maximum state and the inner barrel plate 11 is in the minimum contraction state, the fixed cover 8 no longer blocks the top of the cavity, thereby allowing the formed concrete hollow pipe to be taken out from the top of the cavity, thereby avoiding the situation where the fixed cover 8 blocks the top of the cavity and the concrete hollow pipe cannot be taken out from the top of the cavity.
