Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pier maintenance, and specifically relates to a concrete maintenance device for piers. Background Technology
[0002] Bridge piers are a crucial foundational element in bridge construction. The quality of bridge piers directly affects the safety and reliability of the entire bridge structure, and also determines the bridge's lifespan.
[0003] Cylindrical piers are mostly formed by pouring concrete. After the concrete is poured, it needs to be covered with a membrane to isolate the surface moisture from the atmosphere, reducing moisture evaporation and allowing the moisture inside the membrane to fully react with the cement in the concrete. This reduces the risk of cracking due to insufficient moisture during hydration. Membrane curing is particularly important in hot, windy, and dry environments. The membrane quickly seals the moisture inside the concrete, creating a long-term moist curing environment between the membrane and the concrete surface. After final setting, the concrete surface is free of temperature cracks, resulting in a neat and aesthetically pleasing finish. Membrane curing reduces the frequency of manual watering, saving labor and ensuring timely concrete curing. In extreme weather conditions, the membrane can also prevent surface cracking and retain ground heat.
[0004] Currently, the membrane cladding maintenance of bridge piers relies solely on manual installation: a crane transports personnel and tools to the top of the pier, where manual installation of pulleys is followed by the placement of the cladding membrane on ropes. The membrane is then manually controlled to rotate around the pier. Traditional manual cladding often requires the assistance of other large machinery (such as cranes). Furthermore, the considerable height of bridge piers poses significant safety hazards for workers operating at such heights. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a concrete curing device for bridge piers, which solves the problem that traditional manual mulching often requires the assistance of other large-scale machinery (such as cranes). Furthermore, the considerable height of bridge piers poses significant safety hazards for manual work at heights.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A concrete curing device for pier columns, comprising:
[0008] Two semi-circular bases are detachably connected to form a complete circular base. A lifting cylinder is fixedly connected to the upper end of each semi-circular base. A semi-circular lifting seat is fixedly connected to the telescopic end of the lifting cylinder. The two semi-circular lifting seats are detachably connected to form a complete circular lifting seat. Each of the two semi-circular lifting seats has a semi-circular groove on its inner side, and the two semi-circular grooves form a complete circular groove.
[0009] A drive wheel is rotatably connected to one of the semi-circular lifting seats;
[0010] Two semi-circular rotating seats are detachably connected to form a full circular rotating seat. A semi-circular rotating ring is fixedly connected to the upper inner side of each of the two semi-circular rotating seats. A full circular rotating ring is formed between the two semi-circular rotating rings. The drive wheel is in rolling connection with the semi-circular rotating ring.
[0011] One of the semi-circular rotating rings has an ear plate fixedly connected to its inner side, and a rotating roller is rotatably connected to the ear plate, with a curing film wound on the rotating roller.
[0012] The principles and technical effects of the above technical solution are as follows:
[0013] First, two semi-circular rotating seats are fixedly spliced together to form a full circular rotating seat, which is then fitted onto the cylindrical pier. Simultaneously, two semi-circular bases are symmetrically placed on either side of the cylindrical pier. The lifting cylinder is adjusted to bring the two semi-circular lifting seats to the same height, and then they are fixedly spliced together to form a full circular lifting seat. During this process, the full circular rotating seat is rotated and installed within the full circular groove. At this point, the circumference of the drive wheel is in close contact with the circumference of the full circular rotating seat ring. The lifting cylinder is adjusted to lower the two semi-circular lifting seats to their lowest point, and a section of the curing membrane is glued to the cylindrical pier. The drive wheel rotates, causing the full circular rotating seat ring to rotate. The full circular rotating seat ring then drives the rotating roller and the curing membrane to rotate around the cylindrical pier, winding the curing membrane around it. Simultaneously, the lifting cylinder is driven to raise the full circular lifting seat, causing the curing membrane to wrap around the entire surface of the cylindrical pier, reducing the rate of moisture evaporation.
[0014] In a preferred embodiment, the present invention can be further configured such that a plurality of ball bearings are rotatably connected to the top wall, side wall and bottom wall inside the semi-circular groove.
[0015] In a preferred embodiment, the present invention can be further configured such that: a rotating shaft is fixedly connected to the lower end of the drive wheel, a motor is provided at the lower end of the rotating shaft, and the output end of the motor is fixedly connected to the rotating shaft.
[0016] In a preferred embodiment, the present invention can be further configured as follows: the motor is fixedly connected to the movable seat, and guide rods are slidably connected through both sides of the movable seat. A compression spring is sleeved on the guide rod, and a fixing block is fixedly connected to both ends of the guide rod. The fixing block is fixedly connected to the semi-circular lifting seat, and an adjustment groove is provided on the semi-circular lifting seat. The rotating shaft passes through the adjustment groove.
[0017] In a preferred embodiment, the present invention can be further configured such that: one of the semi-circular rotating seats has mounting grooves at both ends, and the mounting grooves have threaded holes; the other semi-circular rotating seat has mounting blocks that are adapted to the mounting grooves fixedly connected to both ends, and the mounting blocks have first through holes.
[0018] In a preferred embodiment, the present invention can be further configured such that: a first connecting plate is fixedly connected to both ends of the semi-circular lifting seat, and a second through hole is provided on the first connecting plate.
[0019] In a preferred embodiment, the present invention can be further configured such that: a second connecting plate is fixedly connected to both ends of the semi-circular base, and a third through hole is provided on the second connecting plate.
[0020] In a preferred embodiment, the present invention can be further configured such that: a screw is threadedly connected to the semi-circular base, a clamp is fixedly connected to the inner end of the screw, and a rotating component is fixedly connected to the outer end of the screw.
[0021] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0022] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.
[0023] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.
[0024] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.
[0025] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together to form a single unit.
[0026] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.
[0027] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.
[0028] The beneficial effects of this utility model are:
[0029] First, two semi-circular rotating seats are fixedly spliced together to form a full circular rotating seat, which is then fitted onto the cylindrical pier. Simultaneously, two semi-circular bases are symmetrically placed on either side of the cylindrical pier. The lifting cylinder is adjusted to bring the two semi-circular lifting seats to the same height, and then they are fixedly spliced together to form a full circular lifting seat. During this process, the full circular rotating seat is rotated and installed within the full circular groove. At this point, the circumference of the drive wheel is in close contact with the circumference of the full circular rotating seat ring. The lifting cylinder is adjusted to lower the two semi-circular lifting seats to their lowest point, and a section of the curing membrane is glued to the cylindrical pier. The drive wheel rotates, causing the full circular rotating seat ring to rotate. The full circular rotating seat ring then drives the rotating roller and the curing membrane to rotate around the cylindrical pier, winding the curing membrane around it. Simultaneously, the lifting cylinder is driven to raise the full circular lifting seat, causing the curing membrane to wrap around the entire surface of the cylindrical pier, reducing the rate of moisture evaporation.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0038] Based on the concept of this application, combined with Figures 1 to 5 This describes an embodiment of a concrete curing device for a pier column. Specifically, the concrete curing device for a pier column is constructed as a split structure, which has a semi-circular base 1, a semi-circular lifting seat 3, and a semi-circular rotating seat 7 that cooperate with each other. First, two semi-circular rotating seats 7 are fixedly spliced together to form a whole circular rotating seat, which is then fitted onto the cylindrical pier column. At the same time, two semi-circular bases 1 are symmetrically placed on both sides of the cylindrical pier column, and the two semi-circular lifting seats 3 are brought to the same height by adjusting the lifting cylinder 2. The two semi-circular lifting seats 3 are then fixedly spliced together to form a whole circular lifting seat. During this process, the whole circular rotating seat is rotatably installed in the whole circular groove. At this time, the circumference of the drive wheel 6... The two semi-circular lifting seats 3 are in close contact with the circumference of the circular rotating seat ring. By adjusting the lifting cylinder 2, the two semi-circular lifting seats 3 are lowered to the lowest point. A section of the curing film is glued to the cylindrical pier. The driving shaft 5 drives the driving wheel 6 to rotate, which in turn drives the circular rotating seat ring to rotate. The circular rotating seat ring drives the rotating roller 10 and the curing film 11 to rotate around the cylindrical pier, winding the curing film 11 around the cylindrical pier. At the same time, the driving lifting cylinder 2 drives the circular lifting seat to rise, which in turn causes the curing film 11 to wrap around the cylindrical pier, so that the entire surface of the cylindrical pier is wrapped with the curing film 11, reducing the rate of moisture evaporation.
[0039] like Figures 1 to 5 As shown, a concrete curing device for pier columns includes:
[0040] Two semi-circular bases 1 are detachably connected to form a complete circular base. A lifting cylinder 2 is fixedly connected to the upper end of each semi-circular base 1. A semi-circular lifting seat 3 is fixedly connected to the telescopic end of the lifting cylinder 2. Two semi-circular lifting seats 3 are detachably connected to form a complete circular lifting seat. Semi-circular grooves 4 are formed on the inner sides of each semi-circular lifting seat 3, and a complete circular groove is formed between the two semi-circular grooves 4.
[0041] One of the semi-circular lifting seats 3 is rotatably connected to a drive wheel 6;
[0042] Two semi-circular rotating seats 7 are detachably connected to form a whole circular rotating seat. The upper inner side of each of the two semi-circular rotating seats 7 is fixedly connected with a semi-circular rotating ring 8. The two semi-circular rotating rings 8 form a whole circular rotating ring. The drive wheel 6 is in rolling connection with the semi-circular rotating ring 8.
[0043] One of the semi-circular rotating rings 8 has an ear plate 9 fixedly connected to its inner side, and a rotating roller 10 is rotatably connected to the ear plate 9. A curing film 11 is wound on the rotating roller 10.
[0044] In use, first, two semi-circular rotating seats 7 are fixedly spliced together to form a complete circular rotating seat, which is then fitted onto the cylindrical pier. Simultaneously, two semi-circular bases 1 are symmetrically placed on both sides of the cylindrical pier. The lifting cylinder 2 is adjusted to bring the two semi-circular lifting seats 3 to the same height, and then the two semi-circular lifting seats 3 are fixedly spliced together to form a complete circular lifting seat. During this process, the complete circular rotating seat is rotatably installed within the complete circular groove. At this point, the circumference of the drive wheel 6 is in close contact with the circumference of the complete circular rotating seat ring. The lifting cylinder 2 is adjusted to... The two semi-circular lifting seats 3 are lowered to their lowest position, and a section of the curing membrane is fixed to the cylindrical pier with adhesive. The drive wheel 6 is driven to rotate, which in turn drives the circular rotating seat ring to rotate. The circular rotating seat ring drives the rotating roller 10 and the curing membrane 11 to rotate around the cylindrical pier, winding the curing membrane 11 around the cylindrical pier. At the same time, the lifting cylinder 2 drives the circular lifting seat to rise, which in turn causes the curing membrane 11 to wrap around the cylindrical pier, so that the entire surface of the cylindrical pier is wrapped with the curing membrane 11, reducing the rate of moisture evaporation.
[0045] In some embodiments, the protective film 11 adopts a three-layer composite structure, with each layer having complementary functions:
[0046] Outer Layer (Protective Layer): UV-resistant polyester fiber (200D), thickness: 0.2-0.3mm. Function: Resists ultraviolet radiation, weathering, and rain erosion, extending the film's service life (up to 3-5 years of reusable use). Characteristics: The surface is treated with a nano-coating, providing self-cleaning functionality and reducing dust adhesion. Middle Layer (Functional Layer): Hydrogel slow-release layer (3mm), material: Superabsorbent polymer (SAP) and cellulose composite. Function: Absorbs and stores moisture evaporated from the concrete surface (water absorption rate ≥300%), releasing moisture back to the concrete surface when the environment is dry, forming a dynamic humidity balance. It regulates the temperature inside the membrane through a phase change reaction, reducing the temperature difference between the inside and outside of the concrete (temperature control range ±5℃). Inner Layer (Adhesive Layer): Microporous adhesive layer, material: Modified acrylic adhesive, pore size ≤50μm. Function: Mechanically interlocks with the microporous structure of the concrete surface, achieving damage-free bonding (peel strength ≥0.5N / mm). Humidity-responsive self-adhesive: When the relative humidity (RH) is >60%, the adhesive molecular chains expand and the adhesion is enhanced; when the humidity decreases, the adhesion is controllable, avoiding damage to the concrete surface when removing the film.
[0047] In one embodiment of this utility model, in order to enable the circular rotating seat formed by the fixed splicing of two semi-circular rotating seats 7 to rotate well within the circular groove formed by the splicing of two semi-circular grooves 4, a number of balls 12 are rotatably connected on the top wall, side wall and bottom wall inside the semi-circular groove 4. The balls 12 are in contact with the circular rotating seat, which is beneficial to the rotation of the circular rotating seat.

A motor 13 is installed at the lower end of the rotating shaft 5, and the output end of the motor 13 is fixedly connected to the rotating shaft 5. The motor 13 is fixedly connected to the movable seat 14. Guide rods 15 are slidably connected through both sides of the movable seat 14. A compression spring 16 is sleeved on the guide rod 15, and a fixing block 17 is fixedly connected to both ends of the guide rod 15. The fixing block 17 is fixedly connected to the semi-circular lifting seat 3. An adjustment groove 25 is provided on the semi-circular lifting seat 3, and the rotating shaft 5 passes through the adjustment groove 25. In use, the motor 13 can drive the drive wheel 6 to rotate. The compression spring 16 is always in a compressed state, so that the compression spring 16 always pushes the movable seat 14, thereby making the drive wheel 6 closely fit with the whole circular rotating ring formed by the two semi-circular rotating rings 8, thus facilitating the rotation of the whole circular rotating ring.
[0049] In one embodiment of this utility model, one semi-circular rotating seat 7 has mounting grooves 18 at both ends, and threaded holes are formed in the mounting grooves 18. The other semi-circular rotating seat 7 has mounting blocks 19, which are adapted to the mounting grooves 18, fixedly connected to both ends. Each mounting block 19 has a first through hole. In use, the mounting blocks 19 at both ends of the semi-circular rotating seat 7 are engaged in the mounting grooves 18 at both ends of the other semi-circular rotating seat 7 and secured with bolts, thus achieving the installation and splicing of the complete circular rotating seat and the complete circular rotating ring.
[0050] In one embodiment of this utility model, a first connecting plate 20 is fixedly connected to both ends of the semi-circular lifting seat 3, and a second through hole is provided on the first connecting plate 20. In use, two semi-circular lifting seats 3 are fixedly spliced together using bolts and nuts to form a complete circular lifting seat.
[0051] In one embodiment of this utility model, a second connecting plate 21 is fixedly connected to both ends of the semi-circular base 1, and a third through hole is provided on the second connecting plate 21. In use, the two semi-circular bases 1 are fixedly spliced together using bolts and nuts to form a complete circular base.
[0052] In one embodiment of this utility model, a screw 22 is threadedly connected to a semi-circular base 1, a clamping plate 23 is fixedly connected to the inner end of the screw 22, and a rotating component 24 is fixedly connected to the outer end of the screw 22.
[0053] After the two semi-circular bases 1 are fixed and spliced together to form a complete circular base using bolts and nuts, the screws 22 on the two semi-circular bases are symmetrically arranged. By rotating the rotating component 24, the screws 22 are driven to rotate, so that the clamping plate 23 clamps the cylindrical pier, thereby realizing the fixation and positioning of the entire device with the cylindrical pier.
