[0002] In the field of bridge and building construction, the low temperatures in winter pose a serious challenge to the quality of concrete beams and slabs. Traditional curing methods often rely on covering with insulation materials or building simple insulated sheds, but these methods suffer from problems such as rapid heat loss and inaccurate temperature control, which can easily lead to cracks in the beams and slabs due to thermal stress, seriously affecting the structural durability.

[0003] A search revealed Chinese patent application CN216949602U, which discloses a winter insulation and curing device for construction beams and slabs. The device includes multiple insulation and curing components and is capable of providing insulation and curing for outdoor construction beams and slabs under low-temperature conditions.

The insulation components need to be assembled and spliced ​​to form a closed space, which is complex to operate and the sealing depends on manual adjustment. At the same time, it lacks temperature sensing and active insulation functions, making it difficult to adapt to the precise maintenance needs in complex environments. There is an urgent need to design a new type of winter insulation and curing device for construction beams and slabs to solve the above problems. Summary of the Invention

[0010] Preferably, a base is fixedly connected to both sides of the bottom of the main sheath, and rollers are rotatably connected to the inner wall of the bottom of the base, with the outer wall of the bottom of the sliding sleeve contacting the top of the rollers.

[0011] Preferably, the controller has a display screen on top and evenly distributed buttons below the display screen.

[0012] Preferably, the tops of the two side sleeves at opposite ends are fixedly connected with buckles, and the sides of the two buckles that are close to each other are provided with protruding ridges. The bottom of the protruding ridges is at the same level as the top outer wall of the main sleeve. The tops of the two buckles are fixedly connected with support columns. The two sides of the top outer wall of the main sleeve are fixedly connected with threaded sleeves. The inside of the two threaded sleeves is threaded with push rods. One end of the push rod is rotatably connected to its adjacent support column, and the other end of the push rod is drivenly connected to a crank handle.

[0013] Preferably, both ends of the top of the main sheath are fixedly connected to brackets, and the top of the two brackets on the side away from each other is fixedly connected to pin cylinders. The inside of the two pin cylinders is slidably connected to a locking pin, and the top of the two locking pins is fixedly connected to a limiting piece. The diameter of the limiting piece is larger than the inner diameter of the pin cylinder. The side of the two locking pins that are away from each other is set as a guide slope, and the center of the protrusion of the two buckles is provided with a positioning hole adapted to the locking pin.

[0014] Preferably, the top of the main sheath is fixedly connected to two bearing seats on both sides, and the two bearing seats are rotatably connected to the same frame, with a photovoltaic power generation mechanism fixedly connected inside the frame.

[0015] Preferably, a first handle is fixedly connected to the top of the side of the frame away from the bearing seat, and a support platform is fixedly connected to the top of the main sheath near the first handle. The support platform is located below the photovoltaic power generation mechanism. Rotary rods are rotatably connected to both sides of the frame near the support platform. The ends of the two rotating rods away from the frame are rotatably connected to the same roller. The side of the support platform near the bearing seat is set as a slope, and a groove adapted to the roller is opened on the other side of the support platform.

[0016] Compared with the prior art, the present invention provides a winter thermal insulation and curing device for construction beams and slabs, which has the following beneficial effects: 1. This winter thermal insulation and curing device for construction beams and slabs, by setting up electric heaters, springs, pressure switches, and cover plates, and through a retractable thermal insulation sleeve structure composed of a main sleeve and side sleeves, combined with evenly distributed electric heaters inside, achieves precise and uniform heating and insulation of construction beams and slabs. Through the linkage design of springs and pressure switches, in conjunction with temperature sensors and controllers, heating is started when the internal temperature of the thermal insulation sleeve is lower than a preset value, and stops when the preset value is reached, realizing automated control of heating and curing. It can also detect the closure status of the cover plates through pressure switches. If the pressure switches are not triggered simultaneously and the two side cover plates are not fully closed, the controller will cut off the power supply to the electric heaters and issue a warning, avoiding problems such as low heating efficiency or local overheating caused by the thermal insulation sleeve not being sealed, significantly improving the safety, reliability, and automation level of thermal insulation and curing.

[0017] 2. This winter insulation and curing device for construction beams and slabs includes a photovoltaic power generation mechanism, rollers, rotating rods, and a support platform. The photovoltaic power generation mechanism converts solar energy into electrical energy to power the electrical components of the device. The first handle allows operators to easily rotate the frame and adjust the angle of the photovoltaic power generation mechanism to ensure it is always at the optimal light-receiving angle and optimize solar energy conversion efficiency. The support platform provides support for the photovoltaic power generation mechanism. During the upward flipping process of the photovoltaic power generation mechanism, the rotating rod tends to rotate in a vertical state, and the rollers roll along the slope until they pass over the support platform and fall back to the top of the main sheath. At this point, the operator releases the first handle, and the photovoltaic power generation mechanism presses down on the rotating rod under its own weight, causing the rollers to engage in the slots and securing the rollers, thereby fixing the flipped photovoltaic power generation mechanism.

[0018] 3. This winter insulation and curing device for construction beams and slabs achieves automatic fixing during the storage of the side sheath by setting a locking pin and positioning holes. The buckle protrusion presses the inclined surface of the locking pin to make it rise. When it reaches the positioning hole, the locking pin falls into the positioning hole under the action of gravity, completing the fixing. The guide inclined surface design makes the locking pin insertion smoother, and the limiting piece prevents the locking pin from falling off. This structure eliminates the need for additional manual locking operations, simplifies the storage process, improves operational efficiency, and ensures the stability of the side sheath after storage.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-8 A winter insulation and curing device for construction beams and slabs includes a main sheath 1 and two side sheaths 3. The two side sheaths 3 are slidably connected to the interior of both ends of the main sheath 1. The main sheath 1 and the two side sheaths 3 together form an insulation sheath. Evenly distributed electric heaters 30 are fixedly connected inside the insulation sheaths. A cover plate 5 is hung at one end of the side sheath 3 outside the main sheath 1. Hooks 16 are fixedly connected to the outer walls of both sides of the side sheath 3. One cover plate 5 has hanging ears 22 on both sides, which are inserted into the interior of two adjacent hooks 16. Hanging plates 36 are fixedly connected to both sides of the other cover plate 5. A pressure switch 37 is fixedly connected to the middle position of the bottom of the hanging plate 36. A guide rod 41 is fixedly connected to the bottom edge of the hanging plate 36. The rod body 1 is slidably connected to a guide ear 42. A lower clamping plate 40 is fixedly connected to the outer wall of the guide ear 42. A spring 39 is fixedly connected to the top of the lower clamping plate 40. An upper clamping plate 38 is fixedly connected to the top of the spring 39. The top of the upper clamping plate 38 contacts the force-sensitive element of the pressure switch 37. A lifting column 45 is fixedly connected to the bottom of the lower clamping plate 40. A locking block 46 is fixedly connected to the bottom of the lifting column 45. The locking block 46 is locked inside the hook 16 adjacent to itself. A temperature sensor 33 is fixedly connected to the cover plate 5 near the main sheath 1, which is connected to the hanging plate 36. The temperature sensor 33 is connected to a controller 19 through a signal line. The controller 19 is fixedly connected to the side of the cover plate 5 adjacent to itself away from the main sheath 1. A warning mechanism is provided inside the controller 19.

[0023] In use, the main sheath 1 and two side sheaths 3 constitute the insulation sheath. One end of the cover plate 5 of the side sheath 3 is hooked to the hook 16 via the lug 22, and the other end of the cover plate 5 is hooked to the hook 16 via the hanging plate 36, spring 39, lifting column 45 and locking block 46. The controller 1 presets a suitable temperature range for the beam and slab to be stored. When the temperature sensor 33 detects that the internal temperature of the insulation sheath is lower than the preset value, the controller 19 controls the electric heater 30 to be powered on to heat up and raise the internal temperature of the insulation sheath to above the preset value, providing heat for the construction beam and slab. After the cover plate 5 equipped with the controller 19 is hooked to the hook 16, the cover plate 5 compresses the spring 39 downward by its own weight, and the elastic force of the spring 39 presses upward. When the clamp 38 triggers the pressure switch 37 and the spring 39 extends or retracts, the guide rod 41 slides along the inner wall of the guide ear 42 to limit the extension or retraction direction of the spring 39, preventing the pressure switch 37 from deviating. If the two pressure switches 37 are not triggered simultaneously, it means that at least one side of the cover plate 5 is not closed to the accurate position, resulting in the insulation sleeve not being fully closed and the heating effect of the electric heater 30 being poor. At this time, the controller 19 controls the warning mechanism to issue an audible and visual signal to remind the staff and disconnects the electric heater 30 from the power supply. When the cover plate 5 is adjusted and the two pressure switches 37 are triggered simultaneously, the insulation sleeve is fully closed, the warning mechanism stops warning, and the electric heater 30 is powered on again for heating.

[0024] In this invention, a limiting nut 43 is threadedly connected to the bottom of the guide rod 41, and a washer 44 is provided above the limiting nut 43. The limiting nut 43 and the washer 44 are located at one end of the guide rod 41, limiting the reset stroke of the spring 39. By unscrewing the limiting nut 43 from the end of the guide rod 41, the guide ear 42 can be pulled out from the rod body of the guide rod 41, thereby removing the spring 39, the lifting column 45 and the locking block 46 from below the pressure switch 37, which facilitates the installation and maintenance of equipment parts and ensures that the pressure value required for the pressure switch 37 to be triggered is stable.

[0025] In this invention, a second handle 10 is fixedly connected to the outer walls on both sides of the main sheath 1, and a third handle 18 is fixedly connected to the top of the cover plate 5. The second handles 10 on the outer walls on both sides of the main sheath 1 facilitate the operator to carry and move the main sheath 1, and the third handle 18 on the top of the cover plate 5 facilitates the movement and adjustment of the cover plate 5.

[0026] In this invention, guide rails 31 are fixedly connected to the bottom of the inner walls on both sides of the main sheath 1, and sliding sleeves 4 are fixedly connected to the bottom of the outer walls on both sides of the side sheath 3. The two sliding sleeves 4 on the same side sheath 3 are slidably connected to the two guide rails 31 respectively. The guide rails 31 inside the main sheath 1 cooperate with the sliding sleeves 4 outside the side sheath 3, so that the side sheath 3 can slide smoothly inside the main sheath 1, realizing the telescopic function of the side sheath 3 to adapt to beams and slabs of different lengths.

[0027] In this invention, bases 2 are fixedly connected to both sides of the bottom of the main sheath 1. Rollers 32 are rotatably connected to the inner wall of the bottom of the base 2. The outer wall of the bottom of the sliding sleeve 4 contacts the top of the rollers 32. The bases 2 and rollers 32 provide support and movement functions for the side sheath 3, respectively. The contact between the outer wall of the bottom of the sliding sleeve 4 and the top of the rollers 32 reduces the friction when the side sheath 3 slides.

[0028] In this invention, a display screen 21 is provided on the top of the controller 19, and buttons 20 are evenly distributed below the display screen 21. The display screen 21 can be used to display temperature values, and the buttons 20 are used to operate the controller 19.

[0029] In this invention, each of the two side sleeves 3 has a buckle 13 fixedly connected to the top of the opposite end. Each of the two buckles 13 has a protruding ridge on the side that is close to each other. The bottom of the protruding ridge is at the same level as the top outer wall of the main sleeve 1. Each of the two buckles 13 has a support column 14 fixedly connected to the top. Each of the two sides of the top outer wall of the main sleeve 1 has a threaded sleeve 11 fixedly connected to both sides. Each of the two threaded sleeves 11 has a push rod 12 threadedly connected inside. One end of the push rod 12 is rotatably connected to the adjacent support column 14. The other end of the push rod 12 is connected to a crank handle 15. By rotating the crank handle 15, the position of the push rod 12 can be adjusted through the engagement of the threaded sleeve 11, thereby pushing or pulling the buckle 13 and the support column 14 to adjust the position of the side sleeve 3.

[0030] In this invention, brackets 26 are fixedly connected to both ends of the top of the main sheath 1. Pin cylinders 27 are fixedly connected to the top of the two brackets 26 on the side away from each other. Locking pins 28 are slidably connected inside the two pin cylinders 27. Limiting pieces 29 are fixedly connected to the top of the two locking pins 28. The diameter of the limiting pieces 29 is larger than the inner diameter of the pin cylinders 27. The side of the two locking pins 28 that is away from each other is set as a guide slope 34. Positioning holes adapted to the locking pins 28 are opened in the middle of the protrusions of the two buckles 13. 35. During the process of retracting the side sleeve 3 into the main sleeve 1, the protruding edge of the buckle 13 presses against the inclined surface of the locking pin 28, causing the locking pin 28 to rise until it reaches above the positioning hole 35 and falls into the positioning hole 35, thereby automatically fixing the side sleeve 3. This facilitates the overall storage and stacking of the device, improving the portability and storage safety of the device. At the same time, the guide inclined surface reduces the cross-section of the bottom end of the locking pin 28, making it easier to insert into the positioning hole 35. The limiting piece 29 prevents the locking pin 28 from falling off.

[0031] In this invention, the top two sides of the main sheath 1 are fixedly connected to the bearing 6, and the two bearing 6 are rotatably connected to the same frame 7. The photovoltaic power generation mechanism 8 is fixedly connected inside the frame 7. The photovoltaic power generation mechanism 8 inside the frame 7 can convert solar energy into electrical energy to power the electrical components of the device.

[0032] In this invention, a first handle 9 is fixedly connected to the top of the side of the frame 7 away from the bearing 6, and a support platform 23 is fixedly connected to the top of the main sheath 1 near the first handle 9. The support platform 23 is located below the photovoltaic power generation mechanism 8. Rotating rods 24 are rotatably connected to both sides of the side of the frame 7 near the support platform 23. The ends of the two rotating rods 24 away from the frame 7 are rotatably connected to the same roller 25. The side of the support platform 23 near the bearing 6 is set as a slope 48, and the other side of the support platform 23 has a slot 47 adapted to the roller 25. The first handle 9 at the top of the frame 7 facilitates the operator to rotate the frame 7. To adjust the angle of the photovoltaic power generation mechanism 8 and ensure that it is always at the best light-receiving angle to optimize the solar energy conversion efficiency, the support platform 23 provides support for the photovoltaic power generation mechanism 8. During the upward flipping process of the photovoltaic power generation mechanism 8, the rotating rod 24 tends to rotate in a vertical state, and the roller 25 rolls along the slope 48 until the roller 25 passes over the support platform 23 and falls back to the top of the main protective sleeve 1. At this time, the operator releases the first handle 9, and the photovoltaic power generation mechanism 8 presses down on the rotating rod 24 by its own gravity, so that the roller 25 is locked into the slot 47, and the roller 25 is fixed, thereby fixing the flipped photovoltaic power generation mechanism 8.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
