DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0037] like Figures 1 to 5 , Fig.10 As shown, a high pier column overmoulding construction concrete curing device comprises:

[0038] The embedded screw rods 1 are embedded in multiple circles at equal intervals on the surface of the pier along the height direction, and each circle of embedded screw rods 1 is distributed at equal intervals in the circumferential direction of the pier; in this embodiment, four embedded screw rods 1 are arranged in each circle.

[0039] The sealing components are provided in two groups and are distributed on the upper and lower sides. The two groups of sealing components are respectively connected to the upper and lower circles of embedded screws 1 which are adjacent in the height direction, and the sealing components are sleeved on the outside of the bridge pier;

[0040] The curing cloth 2 is a cylindrical structure, and its two ends are respectively fixedly sleeved on the outside of the two sets of sealing components; the sealing components are not only used to support the curing cloth 2 so that the curing part is in a taut state, but also to seal the two ends of the curing cloth 2 and the bridge pier to improve the concrete curing effect. Specifically in this embodiment, the curing pipe can be inserted into the curing cloth 2 after directly opening the curing cloth 2, and the outer end of the curing pipe can be connected to a steam generator to provide hot and humid steam for concrete curing. This is the existing technology and will not be described in detail.

[0041] The sealing assembly comprises an annular housing 3, a first sealing gasket 4, a second sealing gasket 5, a first connecting groove 6, a second connecting groove 7, a threaded sleeve 8, a first axial channel 9 and a second axial channel 10;

[0042] The annular shells 3 are arranged in one-to-one correspondence with the embedded screws 1 in the circumferential direction, and two adjacent annular shells 3 are bolted together, and the first gasket 4 and the second gasket 5 are relatively distributed in the height direction; specifically, in this embodiment, in the sealing assembly located at the top, the first gasket 4 is located at the top of the second gasket 5, and in the sealing assembly located at the bottom, the first gasket 4 is located at the bottom of the second gasket 5. The first gasket 4 and the second gasket 5 in each annular shell 3 are arranged in an arc shape, and the first gaskets 4 adjacent to each other in the circumferential direction of the pier are tightly attached, and the second gaskets 5 adjacent to each other in the circumferential direction of the pier are tightly attached.

[0043] The first sealing gasket 4 and the second sealing gasket 5 are both slidably installed in the annular shell 3 in the annular direction; in the same sealing assembly, when any one of the first sealing gaskets 4 rotates, the other first sealing gaskets 4 rotate synchronously. Similarly, in the same sealing assembly, when any one of the second sealing gaskets 5 rotates, the other second sealing gaskets 5 rotate synchronously.

[0044] The first connecting groove 6 and the second connecting groove 7 are respectively arranged on the opposite sides of the first sealing gasket 4 and the second sealing gasket 5; the first connecting groove 6 and the second connecting groove 7 form a screw groove 11 for tightly contacting the embedded screw 1 and a sleeve groove 12 for rotatably sleeved on the outside of the threaded sleeve 8 between the opposite ends in the circumferential direction, and the sleeve groove 12 is radially located outside the screw groove 11, and the threaded sleeve 8 is threadedly sleeved on the outer end of the embedded screw 1;

[0045] In this embodiment, when the threaded sleeve 8 is located in the sleeve groove 12, since the first connecting groove 6 and the second connecting groove 7 both have a portion covering the outside of the threaded sleeve 8, the threaded sleeve 8 can limit the first sealing gasket 4 and the second sealing gasket 5 in the circumferential direction, thereby achieving the effect of fixing the first sealing gasket 4 and the second sealing gasket 5.

[0046] The threaded sleeve 8 is effectively connected to the embedded screw 1 to achieve stable support for the sealing assembly. At the same time, the embedded screw 1 effectively supports the second sealing pad 5 through the screw groove 11, so that the entire concrete curing device has extremely strong stability. At the same time, the curing cloth 2 is better fixed to improve the concrete curing effect. In particular, after the threaded sleeve 8 is separated from the embedded screw 1 and the sleeve groove 12 is pulled out, the embedded screw 1 supports the entire sealing assembly, which can prevent the curing cloth 2 from being pulled.

[0047] The first axial channel 9 and the second axial channel 10 are respectively opened on the inner surfaces of the first sealing gasket 4 and the second sealing gasket 5, and the outer inner wall surfaces of the first axial channel 9 and the second axial channel 10 are radially located outside the outer end of the embedded screw 1, and the top end of the first axial channel 9 and the bottom end of the second axial channel 10 respectively penetrate the first sealing gasket 4 and the second sealing gasket 5, and the bottom end of the first axial channel 9 and the top end of the second axial channel 10 are respectively connected to the first connecting groove 6 and the second connecting groove 7, and the first axial channel 9 and the second axial channel 10 are respectively located on both sides of the screw groove 11 in the circumferential direction.

[0048] In this embodiment, the first axial channel 9 is aligned with the embedded screw 1 by rotating the first sealing gasket 4, and the sealing assembly can be separated from the embedded screw 1 by moving the sealing assembly upward. The second axial channel 10 is aligned with the embedded screw 1 by rotating the second sealing gasket 5, and the sealing assembly can be put on the embedded screw 1 by moving the sealing assembly upward.

[0049] like Figure 6 and Fig.10 As shown, a lifting ring 13 is fixedly installed on the outside of the ring shell 3, a guide rod 14 is arranged on the inner surface of the lifting ring 13, a guide hole 15 is opened in the threaded sleeve 8, and the guide hole 15 is sleeved on the inner end of the guide rod 14. The lifting ring 13 is used to connect the hook of the crane, and then the crane can be used to lift the two sets of sealing components upward to realize the climbing of the concrete curing device as a whole outside the bridge section, so as to realize the segmented curing operation of the concrete according to the construction process of segmented pouring of the bridge section.

[0050] The cooperation between the guide hole 15 and the guide rod 14 realizes effective support for the threaded sleeve 8. No matter the threaded sleeve 8 is in a state of being threadedly connected to the embedded screw rod 1 or being pulled out from the sleeve groove 12, the threaded sleeve 8 is effectively supported on the guide rod 14 to prevent the threaded sleeve 8 from being lost when the concrete curing device as a whole is displaced on the pier, and the threaded sleeve 8 is always kept aligned with the corresponding embedded screw rod 1 in the circumferential direction.

[0051] like Figure 5 and Fig.10 As shown, a first sealing block 16 for sealing the second axial channel 10 is provided on the side of the first sealing gasket 4 facing the second sealing gasket 5, and a second sealing block 17 for sealing the first axial channel 9 is provided on the side of the second sealing gasket 5 facing the first sealing gasket 4, and the opposite ends of the first sealing block 16 and the second sealing block 17 are tangent to the two sides of the screw groove 11 respectively.

[0052] The first sealing block 16 and the second sealing block 17 respectively block the second axial channel 10 and the first axial channel 9 to ensure the sealing during concrete curing operation and improve the curing effect. At the same time, the first sealing block 16 and the second sealing block 17 can increase the contact area between the first sealing gasket 4 and the second sealing gasket 5 and the embedded screw 1, so that the embedded screw 1 has a better limiting effect on the first sealing gasket 4 and the second sealing gasket 5 in the circumferential direction.

[0053] like Figure 5 and Fig.10 As shown, a rotation channel 18 for relative rotation of the first sealing gasket 4 and the second sealing gasket 5 is formed between the first sealing block 16 and the end of the second connecting groove 7 away from the screw groove 11 and between the second sealing block 17 and the end of the first connecting groove 6 away from the screw groove 11.

[0054] When any one of the first axial channel 9 and the second axial channel 10 is aligned with the embedded screw 1 in the height direction, the first sealing block 16 is in contact with the end of the second connecting groove 7 away from the screw groove 11, and the second sealing block 17 is in contact with the end of the first connecting groove 6 away from the screw groove 11.

[0055] In this way, the setting of the rotating channel 18 can limit the maximum rotation angle of the first sealing gasket 4 and the second sealing gasket 5, and further, the two extreme positions of the first sealing gasket 4 and the second sealing gasket 5 in the circumferential direction respectively correspond to the state where the screw groove 11 is sleeved with the embedded screw 1 and the state where the first axial channel 9 or the second axial channel 10 is aligned with the embedded screw 1, which is more convenient for operation and positioning.

[0056] like Figure 7 , Fig. 9 and Fig.10 As shown, an arc-shaped rack 19 is provided on the outer surface of the second sealing gasket 5, and a rotating shaft 20 is rotatably installed in the annular shell 3. The two ends of the rotating shaft 20 are respectively connected with an internal gear 21 and an external gear 22, and the internal gear 21 is meshed with the arc-shaped rack 19. A slide seat 23 is provided on the side of the second sealing gasket 5 facing the two groups of sealing components. A rotating arm 24 is rotatably connected to the slide seat 23, and a roller 25 for rolling on the surface of the pier is provided at the end of the rotating arm 24 away from the slide seat 23. A spur rack 26 is provided on the slide seat 23, and an inner tension spring 27 is provided on the side of the slide seat 23 facing the pier. When the opposite ends of the two rotating arms 24 distributed up and down are squeezed, the slide seat 23 is driven to move outward, which is used to control the circumferential sliding of the second sealing gaskets 5 in the two groups of sealing components, so that the second axial channel 10 is aligned with the embedded screw 1.

[0057] During the rising process of the sealing assembly at the bottom, after the roller 25 at the bottom contacts the roller 25 at the top, the opposite ends of the rotating arm 24 are pressed against each other, and the rotating arm 24 is blocked by the bridge pier, so that the outer end of the rotating arm 24 slides outward, at which time, the slide 23 is driven to move outward, and the inner tension spring 27 is stretched. The slide 23 drives the spur rack 26 to move outward, and when the spur rack 26 passes the outer gear 22, it drives the outer gear 22 to rotate, and the outer gear 22 drives the inner gear 21 to rotate through the rotating shaft 20, and the inner gear 21 drives the second sealing gasket 5 to rotate through the arc-shaped rack 19.

[0058] At this time, the second sealing gaskets 5 in the two sealing assemblies rotate simultaneously, so that the second sealing gasket 5 located at the bottom rotates to a state where the top of the second axial channel 10 is aligned with the embedded screw 1 located above it, and the second sealing gasket 5 located at the top rotates to a state where the second axial channel 10 is aligned with the embedded screw 1 located inside it.

[0059] Furthermore, as the sealing component at the bottom continues to move upward, it will push the sealing component at the top to move upward, so that the sealing component at the top is pulled out of the embedded screw 1 located inside it, and the sealing component at the bottom is put on the embedded screw 1.

[0060] Furthermore, a slide rail 28 is fixedly provided on one side surface of the annular shell 3 facing between the two sets of sealing components, the slide seat 23 is slidably mounted on the slide rail 28 , and the inner end of the inner tension spring 27 is fixedly connected to the slide rail 28 .

[0061] like Figure 7 and Fig. 9 As shown, the two rotating arms 24 distributed up and down are staggered in the circumferential direction of the bridge pier, and the rollers 25 are rotatably mounted on the opposite sides of the two rotating arms 24 distributed up and down. A bar-shaped limit block 32 is fixedly arranged on the side of the rotating arm 24 located at the bottom away from the roller 25, and the upper and lower ends of the limit block 32 are both in an arc shape with the axis of the roller 25 as a circle. A limit groove 33 is provided on the side of the rotating arm 24 located at the top away from the roller 25, and a bar-shaped notch 34 is provided at the bottom end of the limit groove 33 for the limit block 32 to be inserted into the limit groove 33 from bottom to top. The width of the notch 34 is adapted to the limit block 32, and when the slide 23 is located at the innermost position, the limit block 32 and the notch 34 are in a vertical and aligned state, and when the slide 23 moves outward, the limit block 32 located in the limit groove 33 is in a staggered state with the notch 34.

[0062] In this embodiment, the rotating arms 24 and rollers 25 distributed up and down are arranged to be staggered in the circumferential direction, so that after the opposite ends of the two rotating arms 24 distributed up and down are close to each other, the limit block 32 will be inserted into the limit groove 33 from the notch 34. At this time, the opposite ends of the two rotating arms 24 are concentric, and the two rollers 25 overlap in their axial direction.

[0063] During the process of the two ends of the two rotating arms 24 being pressed against each other, the limit block 32 will rotate in the limit slot 33, and the limit block 32 and the slot 34 will be staggered, so that the two rotating arms 24 are effectively connected in the height direction. Therefore, if the two rotating arms 24 want to be separated, they must be restored to the initial state, so that the limit block 32 and the slot 34 are both in a vertical state. Such a setting is more conducive to the resetting of the rotating arms 24.

[0064] like Figures 7 to 9 As shown, a sleeve 29 is fixedly provided at the bottom of the upper slide 23, and an insertion rod 30 is fixedly provided at the top of the lower slide 23. When the slide 23 moves outward to the outermost position, the bottom of the sleeve 29 is supported by the insertion rod 30. A pressure rod 31 is fixedly provided on the sleeve 29 and the insertion rod 30. When the slide 23 is in the innermost position, the pressure rod 31 presses the rotating arm 24 against the bridge pier.

[0065] Before the opposite ends of the two rotating arms 24 distributed up and down come into contact, the insert rod 30 will be inserted into the sleeve 29. This arrangement allows the sliding seats 23 distributed up and down to be connected as a whole in their moving direction, and the insert rod 30 and the sleeve 29 are also connected as a whole. Furthermore, during the outward displacement of the sliding seat 23, the insert rod 30 and the sleeve 29 are synchronously displaced outward. At this time, the insert rod 30 and the sleeve 29 will push the maintenance cloth 2 folded into the inner side of the ring shell 3 outward, so that during the approach of the two sealing components, the maintenance cloth 2 will not be over-extruded and will not hinder the movement of the sealing components. In particular, it can ensure that the two sealing components can move relative to each other to the shortest distance to ensure that the rotating arm 24 can rotate to the maximum extent, and further ensure that during the approach of the two sealing components, all the second sealing pads 5 can rotate to the maximum angle to achieve the alignment of the second axial channel 10 with the embedded screw 1.

[0066] In the initial state, the elastic force of the inner tension spring 27 is transmitted to the pressure rod 31 through the slide 23, and finally applied to the outer surface of the rotating arm 24, ensuring that the roller 25 always moves closely on the surface of the pier and ensuring that the limit block 32 and the slot 34 always remain aligned in the initial state.

[0067] When using the high pier column overmolding construction concrete curing device provided in this embodiment, the following steps can be followed:

[0068] Among them, in order to facilitate the understanding of this embodiment, the first sealing gasket 4 and the second sealing gasket 5 in the upper sealing component are expressed as the upper first sealing gasket 4 and the upper second sealing gasket 5, and the upper first sealing gasket 4 is located on the top of the upper second sealing gasket 5, and the first sealing gasket 4 and the second sealing gasket 5 in the lower sealing component are expressed as the lower first sealing gasket 4 and the lower second sealing gasket 5, and the lower first sealing gasket 4 is located at the bottom of the lower second sealing gasket 5, and so on. The other structures in the two groups of sealing components are expressed in the above manner.

[0069] When the first stage of concrete pouring is being maintained, the four upper ring shells 3 can be directly hoisted by a crane, then put on the bridge pier, and fixed by the threaded sleeve 8 and the first circle of embedded screws 1. Similarly, the four lower ring shells 3 can be directly hoisted by a crane, then put on the bridge pier, and fixed by the second circle of embedded screws 1. The adjacent two upper ring shells 3 and the adjacent two lower ring shells 3 are fixed by bolt connection, and then the first stage of concrete pouring can be maintained.

[0070] When the second section of poured concrete needs to be maintained:

[0071] Step 1: first rotate the threaded sleeve 8 sleeved outside the first circle of embedded screw 1 so that the threaded sleeve 8 is pulled out of the lower sleeve groove 12.

[0072] Step 2: directly pull the bottom channel opening of the lower first axial channel 9 on any lower first sealing gasket 4 to rotate the lower first sealing gasket 4 by a distance of a rotating channel 18. At this time, the lower first axial channel 9 is aligned with the first circle of embedded screw 1.

[0073] Step 3: Use a crane to hang the upper sealing assembly, and rotate the threaded sleeve 8 sleeved outside the second circle of embedded screw 1 so that the threaded sleeve 8 is pulled out of the upper sleeve groove 12.

[0074] Step 4: Lift the lower sealing assembly upward as a whole, so that the lower sealing assembly moves upward as a whole outside the bridge pier. During this process, the lower roller 25 rolls on the surface of the bridge pier.

[0075] When the insertion rod 30 is inserted into the sleeve 29 and the stopper 32 is inserted into the stopper groove 33, mutual extrusion begins to form between the opposite ends of the upper rotating arm 24 and the lower rotating arm 24. At this time, the inner ends of the upper rotating arm 24 and the lower rotating arm 24 are restricted by the bridge pier, so that the outer ends of the upper rotating arm 24 and the lower rotating arm 24 swing outward with the inner ends as the center, the slide 23 moves outward and compresses the spring, and the insertion rod 30 and the sleeve 29 move outward synchronously as a whole, and push the curing cloth 2 outward.

[0076] When the slide 23 slides outward to the farthest position, the rod 30 and the sleeve are displaced outward to the farthest position, so that the folded maintenance cloth 2 located between the two sealing components is loosened on the outer side between the upper ring shell 3 and the lower ring shell 3, and the bottom end of the sleeve 29 is supported by the rod 30. At this time, the rod 30 cooperates with the sleeve 29 and the upper rotating arm 24 cooperates with the lower rotating arm 24, and under the support of the inner side provided by the pier, a stable triangular support is formed, so that the upper sealing component is stably supported by the lower sealing component.

[0077] At the same time, during the outward displacement of the slide 23 on the upper and lower sealing assemblies, the outer gear 22 is driven to rotate by the spur rack 26, and the outer gear 22 drives the inner gear 21 to rotate through the rotating shaft 20. The inner gear 21 causes the two upper second sealing gaskets 5 and the lower second sealing gasket 5 to rotate synchronously through the arc rack 19. At the same time, during the rotation of the lower second sealing gasket 5, the first connecting groove 6 is pushed away from the inner wall of one side of the screw groove 11 through the lower second sealing block 17, so that the lower first sealing gasket 4 rotates synchronously. Finally, the upper second axial channel 10 and the lower second axial channel 10 are aligned with the second circle of embedded screw 1 at the same time, and the part of the lower screw groove 11 located on the lower first sealing gasket 4 is aligned with the second circle of embedded screw 1.

[0078] Furthermore, as the lower sealing assembly continues to move upward, the upper sealing assembly will be lifted up as a whole, so that the upper sealing assembly will automatically detach from the second circle of embedded screws 1, and the lower sealing assembly can automatically put on the second circle of embedded screws 1 until the second circle of embedded screws 1 is the same as the lower screw groove 11 in the height direction.

[0079] Step 5: Control the crane to keep the height of the lower sealing assembly unchanged and lift the upper sealing assembly upward.

[0080] During the rising process of the upper sealing assembly, the upper rotating arm 24 and the lower rotating arm 24 cannot be separated because the limit block 32 and the notch 34 of the limit groove 33 are offset. At this time, the upper sealing assembly moves upward, and the upper rotating arm 24 and the lower rotating arm 24 will be reset at the same time.

[0081] During this process, the slide 23 stably moves inward and resets, and uses the spur rack 26 to pass through the outer gear 22 in the opposite direction, and drives the outer gear 22 to rotate in the opposite direction, so that the lower second axial channel 10 is misaligned with the second circle of embedded screw 1, and the part of the lower screw groove 11 located on the lower second sealing gasket 5 is covered with the second circle of embedded screw 1. At this time, the lower screw groove 11 is in a state of stably covering the second circle of seedling raising screw. The upper second axial channel 10 is misaligned with the third circle of embedded screw 1, and the part of the upper screw groove 11 located on the second sealing gasket 5 is aligned with the third circle of embedded screw 1.

[0082] Step 6: Before the upper first sealing gasket 4 contacts the third circle of embedded screws 1 , manually pull the top channel opening of the upper first axial channel 9 to rotate the upper first sealing gasket 4 to a state where the upper first axial channel 9 is aligned with the third circle of embedded screws 1 .

[0083] Step seven, continue to lift the upper sealing assembly upwards so that the upper sealing assembly is covered with the third circle of embedded screws 1, then manually operate the upper first sealing pad 4 to rotate and reset, and then respectively thread the threaded sleeves 8 on the upper sealing assembly and the lower sealing assembly to the third circle of embedded screws 1 and the second circle of embedded screws 1, so that the high pier column flip mold construction concrete curing device can be climbed outside the pier, and the sequential segmented curing operation of different sections of slow-setting soil can be achieved.

[0084] The technical scope of the present invention is not limited to the contents of the first description. Those skilled in the art can make various deformations and modifications to the first embodiment without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
