Description

Technical Field

[0001] This invention relates to the field of building maintenance and construction technology, specifically to a membrane curing device for large-volume concrete pouring columns. Background Technology

[0002] In the field of building engineering, numerous concrete columns are often required to support elevated roads or buildings. Compressive strength is one of the important mechanical properties of concrete. The increase in concrete strength is not only related to the raw materials and pouring process, but also directly related to the curing conditions.

[0003] Generally, when maintaining columns, a protective film is used. This film-based maintenance provides insulation and moisture retention, resulting in better curing and shaping. The column surface does not crack due to excessive water loss, thus ensuring the column's strength.

[0004] In existing technologies, when covering columns with membranes, stirrups and steel frames are typically used to fix both ends of the membrane. The steel frame is then hoisted up, with the stirrups fixed to the top of the column. The steel frame is then slowly lowered to cover the column with membrane. However, this method has the drawback that the membrane does not adhere tightly to the column surface after covering. Water on the column evaporates and flows downwards along the inside of the membrane, causing water to flow to the bottom of the column. This reduces the curing effect above the column. Furthermore, the lack of adhesion between the membrane and the column causes the membrane to sway in the wind, making it prone to damage. Summary of the Invention

[0005] The purpose of this invention is to provide a membrane curing device for large-volume concrete columns, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A membrane curing device for large-volume concrete columns includes a fixing ring and a top seat. The fixing ring is rotatably provided with an inner gear ring and an outer gear ring. A first clamping plate is fixedly provided on the outer gear ring, and a second clamping plate is slidably provided on the outer gear ring. The first clamping plate and the second clamping plate cooperate to clamp one end of the membrane. A third clamping plate is slidably provided on the top seat. The third clamping plate cooperates with the top seat to clamp the other end of the membrane. The internal gear ring is provided with a winding assembly, which is used to wind the membrane so that it is tightly attached to the column; It also includes a reversing component, in which the fixing ring drives the inner gear ring and the outer gear ring to rotate in opposite directions during the falling film process.

[0015] Preferably, a third spring is provided between the lifting seat and the fixed block, and the two ends of the third spring are fixedly connected to the lifting seat and the fixed block respectively.

[0016] In the above technical solution, the membrane curing device for large-volume concrete pouring columns provided by the present invention has the following beneficial effects: During the process of the fixed ring falling to cover the column with the membrane, the inner and outer toothed rings rotate in opposite directions through the reversing component. When the outer toothed ring rotates, it covers and wraps the cylindrical membrane around the column.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please refer to 1-8. A membrane curing device for large-volume concrete columns includes a fixing ring 1 and a top seat 2. The fixing ring 1 is rotatably equipped with an inner gear ring 14 and an outer gear ring 11. A first clamping plate 12 is fixedly mounted on the outer gear ring 11, and a second clamping plate 13 is slidably mounted on the outer gear ring 11. The first clamping plate 12 and the second clamping plate 13 cooperate to clamp one end of the membrane. A third clamping plate 25 is slidably mounted on the top seat 2, and the third clamping plate 25 cooperates with the top seat 2 to clamp the other end of the membrane. A winding assembly is provided on the inner gear ring 14 to wind the membrane, making it tightly adhere to the column. A reversing assembly is also included. During the process of the fixing ring 1 lowering to form the membrane, the reversing assembly drives the inner gear ring 14 and the outer gear ring 11 to rotate in opposite directions, and the first clamping plate 12 and the second clamping plate 13... One end of the membrane is clamped and fixed, and the other end of the membrane is clamped and fixed by the third clamping plate 25 and the top seat 2. When the membrane is applied to the column, the top seat 2 is placed on the top of the column, causing the fixing ring 1 to fall. The reversing component causes the inner toothed ring 14 and the outer toothed ring 11 to rotate in opposite directions. When the fixing ring 1 falls to apply the membrane, the outer toothed ring 11 rotates, and the membrane is rotated by the first clamping plate 12 and the second clamping plate 13, and wound onto the column. This prevents water droplets generated on the inner wall of the membrane from flowing down the membrane to the bottom of the column, thus improving the overall maintenance effect of the column. When the inner toothed ring 14 rotates, it winds the membrane through the winding component, and the winding direction is opposite to the direction in which the membrane winds the column. This not only makes the membrane fit the column better and enhances the maintenance effect of the column, but also improves the stability of the membrane and prevents it from swaying in the wind and being damaged.

[0024] Specifically, the winding assembly includes a rotating shell 3 fixedly mounted on an inner gear ring 14, a guide rail 31 fixedly mounted on the rotating shell 3, a first rotating shaft 32 rotatably mounted on the guide rail 31, a first reel 33 fixedly mounted on the first rotating shaft 32, a pull ring 22 fixedly mounted on a top seat 2, and a rope 34 positioned between the first reel 33 and the pull ring 22. The two ends of the rope 34 are fixedly connected to the first reel 33 and the pull ring 22, respectively. When the top seat 2 is lowered to the top of the column, the inner gear ring 14 rotates, driving the rotating shell 3 to rotate... As the moving shell 3 moves with the internal gear ring 14, the first rotating shaft 32 and the first reel 33 rotate and loosen the rope 34 under the action of the pull ring 22, so that it wraps around the membrane, thereby improving the stability of the membrane and preventing the membrane from being damaged by swaying in the wind. Furthermore, a friction plate is set between the first rotating shaft 32 and the guide rail 31 to increase the friction between the first rotating shaft 32 and the guide rail 31, which can effectively prevent the first reel 33 from loosening the rope 34 under the influence of external force before the fixed ring 1 begins to fall.

[0025] In a further embodiment of the present invention, a pressing frame 35 is slidably disposed on the guide rail 31, and a plurality of second springs 36 are disposed between the pressing frame 35 and the rotating shell 3. The two ends of the second springs 36 are fixedly connected to the pressing frame 35 and the rotating shell 3, respectively. When the rope 34 on the first reel 33 is used up, and the first reel 33 is replaced, the pressing frame 35 is pressed down, the second springs 36 are compressed, and the pressing frame 35 is disengaged from the first rotating shaft 32, so that the first reel 33 can be removed along the guide rail 31. When installing the first reel 33, the first rotating shaft 32 on the first reel 33 is made to abut against the inclined surface on the pressing frame 35, so that the pressing frame 35 slides to compress the second springs 36. After the first rotating shaft 32 passes the pressing frame 35, the pressing frame 35 re-engages with it, fixing the first rotating shaft 32 and the first reel 33, effectively improving the replacement efficiency of the first reel 33.

[0026] Furthermore, the reverse assembly includes a transmission gear 4 rotatably mounted on the fixed ring 1. Both the inner gear ring 14 and the outer gear ring 11 mesh with the transmission gear 4 for transmission. The transmission gear 4 is located between the inner gear ring 14 and the outer gear ring 11. Thus, when the transmission gear 4 rotates, the inner gear ring 14 and the outer gear ring 11 rotate in opposite directions, thereby causing the winding direction of the rope 34 to be opposite to the winding direction of the membrane. This further improves the stability of the membrane and makes the membrane fit more closely to the column.

[0027] Furthermore, a fixed seat 5 is fixedly mounted on the fixed ring 1, a second rotating shaft 51 is rotatably mounted on the fixed seat 5, a second bevel gear 52 is fixedly mounted on the second rotating shaft 51, and a first bevel gear 41 is fixedly mounted on the transmission gear 4. The first bevel gear 41 meshes with the second bevel gear 52 for transmission. When the second rotating shaft 51 rotates, the transmission gear 4 rotates through the transmission between the second bevel gear 52 and the first bevel gear 41, thereby causing the internal gear ring 14 and the external gear ring 11 to rotate.

[0028] In a further embodiment of the present invention, a support rod 6 is rotatably mounted on the second rotating shaft 51, a roller 61 is rotatably mounted on the support rod 6, a first pulley 53 is fixedly mounted on the second rotating shaft 51, a second pulley 62 is fixedly mounted on the roller 61, and a belt 54 is driven between the first pulley 53 and the second pulley 62. When the support rod 6 rotates, the roller 61 on the support rod 6 comes into contact with the side wall of the column. After the roller 61 comes into contact with the side wall of the column, during the falling process of the fixing ring 1, the roller 61 will also rotate due to the friction between it and the column. When the roller 61 rotates, the second rotating shaft 51 is rotated through the transmission between the second pulley 62, the belt 54 and the first pulley 53, thereby driving the inner gear ring 14 and the outer gear ring 11 to rotate through the transmission gear 4.

[0029] In the embodiments provided by the present invention, a fixing block 7 is fixedly installed on the fixing base 5, a lifting seat 71 is slidably installed on the fixing block 7, a square tube 63 is fixedly installed on the support rod 6, a telescopic rod 64 is slidably installed on the square tube 63, and the telescopic rod 64 is rotatably connected to the lifting seat 71. After the fixing ring 1 is fitted onto the outside of the column, when the lifting seat 71 descends, it drives the telescopic rod 64 and the square tube 63 to rotate, thereby driving the support rod 6 to rotate and causing the roller 61 to fit against the side wall of the column. When the fixing ring 1 is not yet fitted onto the outside of the column, the lifting seat 71 is located at the top, and at this time the support rod 6 is in the open state to avoid collision between the fixing ring 1 and the column when the fixing ring 1 is fitted onto the column.

[0030] Specifically, a connecting ring 8 is slidably inserted into the top seat 2, and a second reel 73 is rotatably mounted on the fixing block 7. A steel wire rope 74 is installed between the second reel 73 and the connecting ring 8, with both ends of the steel wire rope 74 fixedly connected to the second reel 73 and the connecting ring 8, respectively. A spiral spring is installed between the second reel 73 and the fixing block 7. After the fixing ring 1 is fitted onto the outside of the column, the connecting ring 8 disengages from the top seat 2, the spiral spring contracts, and the second reel 73 rotates to wind up the steel wire rope 74. During the winding process, the connecting ring 8 abuts against the lifting seat 71, the lifting seat 71 descends, causing the support rod 6 to rotate, and the roller 61 abuts against the column. During the hoisting process, the top seat 2 is lifted by the lifting ring 21 on the top seat 2, and the fixing ring 1 is lifted by the connecting ring 8 and the steel wire rope 74.

[0031] In a further embodiment of the present invention, a locking block 23 is slidably disposed on the top seat 2, and the locking block 23 is engaged with the insertion ring 8; a plurality of first springs 24 are disposed between the locking block 23 and the top seat 2, and the two ends of the first springs 24 are respectively fixedly connected to the locking block 23 and the top seat 2. During the process of lifting the top seat 2, the locking block 23 engages with the insertion ring 8 under the action of the first springs 24, fixing the insertion ring 8, so that the fixing ring 1 can be lifted by the steel wire rope 74 while the top seat 2 is being lifted. After the top seat 2 is placed on the top of the column, the fixing ring 1 is also sleeved on the outside of the column. The locking block 23 first contacts the top of the column, and under the action of the gravity of the top seat 2, the first springs 24 are compressed, and the locking block 23... 3. Slide the ring 73 into the top seat 2 and disengage it from the insertion ring 8. Under the action of the spiral spring, the second reel 73 rotates to wind up the wire rope 74 and the insertion ring 8 abuts against the lifting seat 71, causing the lifting seat 71 to descend and the roller 61 to abut against the side wall of the column. During hoisting, by pulling the insertion ring 8, the second reel 73 rotates, tightening the spiral spring and inserting the insertion ring 8 into the top seat 2. During the insertion process, the insertion ring 8 abuts against the inclined surface of the locking block 23, causing the locking block 23 to slide and compress the first spring 24. After the insertion ring 8 passes the locking block 23, the first spring 24 returns to its original position, causing the locking block 23 to engage with the insertion ring 8, so that the top seat 2 and the fixed ring 1 can be hoisted.

[0032] A third spring 72 is provided between the lifting seat 71 and the fixed block 7. The two ends of the third spring 72 are fixedly connected to the lifting seat 71 and the fixed block 7 respectively. When the insertion ring 8 is not in contact with the lifting seat 71, the support rod 6 opens under the action of the third spring 72 to avoid collision between the support rod 6 and the roller 61 and the column during hoisting and when the fixed ring 1 is put on the outside of the column, which would cause damage to the appearance of the column. When the insertion ring 8 is in contact with the lifting seat 71, the third spring 72 is compressed, causing the support rod 6 to slide and the roller 61 to contact the column.

[0033] Working principle: During the film covering operation, the first clamping plate 12 and the second clamping plate 13 first clamp and fix one end of the film, and then the third clamping plate 25 and the top seat 2 clamp and fix the other end of the film. The films are then stacked. Subsequently, the insertion ring 8 and the wire rope 74 are pulled out, and the insertion ring 8 is inserted into the top seat 2. Under the action of the first spring 24, the locking block 23 engages with the insertion ring 8. The top seat 2 is lifted by a crane or tower crane through the lifting ring 21, and the fixing ring 1 is lifted by the action of the wire rope 74. After being lifted, it is moved. The column is lowered to the top, causing the top seat 2 to fall to the top of the column. The fixing ring 1 is sleeved on the outside of the column. When the top seat 2 falls to the top of the column, under the action of gravity, the locking block 23 squeezes the first spring 24 and slides, releasing the lock on the insertion ring 8. Under the reset action of the spiral spring, the second reel 73 rotates to wind up the wire rope 74 and causes the insertion ring 8 to abut against the lifting seat 71, causing the lifting seat 71 to descend and squeeze the third spring 72. As the lifting seat 71 descends, the telescopic rod 64 and the square tube 63 rotate with the support rod 6. As the support rod 6 rotates, the roller 61 comes into contact with the side of the column. Therefore, during the descent of the fixing ring 1, the roller 61 rotates. While the roller 61 rotates, the transmission gear 4 rotates via the second rotating shaft 51, the second bevel gear 52, and the first bevel gear 41. The transmission gear 4 drives the inner gear ring 14 and the outer gear ring 11 to rotate. The outer gear ring 11 drives the first clamping plate 12 and the second clamping plate 13 to rotate. This causes the fixing ring 1 to rotate along with the film during the descent, causing the film to wrap around the column. Simultaneously, the inner... The toothed ring 14 rotates with the rotating shell 3, and during the rotation, the first reel 33 rotates, loosening the rope 34 so that the rope 34 is wrapped around the membrane. That is, the membrane is wrapped around the column, and the rope 34 is wrapped around the membrane. Since the inner toothed ring 14 and the outer toothed ring 11 rotate in opposite directions, the rope 34 is wrapped around the membrane against the direction of membrane rotation, which further improves the stability of the membrane and the maintenance effect on the column. After the fixing ring 1 falls to the bottom of the column, the connecting plate 15 is removed, so that the fixing ring 1 can be detached from the column, making it easier to cover the remaining columns with membrane.

[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
