Description

Technical Field

[0001] This utility model provides a lifting device for preventing delamination during high-level concrete pouring, belonging to the technical field of auxiliary equipment for concrete pouring. Background Technology

[0002] Concrete pouring is a common procedure in building construction. However, when poured from a height, the concrete is affected by gravity during its descent, causing the coarse and fine aggregates to separate, resulting in stratification and segregation. This stratification can severely affect the quality of the concrete pouring and the durability of the structure, ultimately leading to a decline in the safety performance of the building.

[0003] Currently, the main methods for solving the problem of sludge formation in high-level concrete pouring include using auxiliary equipment such as guide pipes and chutes. While these methods can reduce sludge formation to some extent, guide pipes and chutes are prone to clogging and require frequent cleaning. A more ideal approach is to slowly transport the concrete in its normal state to the bottom of the pouring body and then release it, avoiding sludge segregation caused by prolonged free fall. However, this method is often limited by the space within the pouring body. When the concrete is transported deep into the pouring body, it is far from the workers, making it inconvenient for them to open the concrete storage equipment to release it. Therefore, a new type of lifting device to prevent sludge formation in high-level concrete pouring is needed to address these issues. Utility Model Content

[0004] The technical problem this invention aims to solve is that high-level concrete pouring is prone to causing stratification, and due to the limited space of the pouring body, it is inconvenient to release the concrete transported to the bottom of the pouring body by the lifting device.

[0005] To solve the above problems, the proposed technical solution is as follows: a high-level concrete pouring anti-delamination lifting device, comprising a support plate placed above the pouring body, with a support frame fixedly connected to the support plate; and further comprising:

[0006] The storage cylinder and the lifting assembly are provided. The storage cylinder is located below the support plate and is horizontally suspended below the support frame by the lifting assembly. A conical groove is provided at the bottom of the storage cylinder, and a conical block is placed in the conical groove. A lifting rope is connected to the conical block. The lifting rope passes upward through the support plate.

[0007] The storage cylinder has an insertion hole, and a limiting component corresponding to the insertion hole is slidably installed inside the support frame; the adjustment box is equipped with an adjustment component that can drive the limiting component to rise and fall.

[0008] As an improvement, the lifting assembly includes a take-up and release motor, a take-up and release roller, and a lifting rope; the take-up and release motor is fixedly mounted on the support frame, and the take-up and release roller is fixedly sleeved on the output shaft of the take-up and release motor; the lifting rope is wound around the take-up and release roller, passes through the support frame and the support plate, and is fixedly connected to the storage cylinder.

[0009] As an improvement, the limiting component includes a lifting plate and a fixing rod. The lifting plate is slidably disposed within the support frame, and the fixing rod is fixedly connected to the lower part of the lifting plate, with the fixing rod located directly above the insertion hole.

[0010] As an improvement, the lifting plate has a through hole, through which the lifting rope passes; there are two insertion holes, and two fixing rods corresponding to the insertion holes are provided.

[0011] As an improvement, the adjustment assembly includes a rotary motor, a lead screw, and a slider. The rotary motor is mounted on the adjustment box, the lead screw is rotatably mounted inside the adjustment box, and the lead screw is fixedly connected to the output shaft of the rotary motor. The slider is located inside the adjustment box and is threadedly connected to the lead screw.

[0012] As an improvement, the support plate is provided with a filling hole corresponding to the storage cylinder; the position where the lifting rope connects to the conical block is far from the center of the conical block.

[0013] The beneficial effects of this utility model are:

[0014] The storage cylinder is horizontally suspended below the support frame via a lifting assembly, which can transport the storage cylinder carrying concrete to the bottom of the pouring body. The bottom of the storage cylinder has a conical groove, and a conical block is placed inside the groove. The conical block can be used to block the bottom of the storage cylinder to prevent the placed concrete from falling. A lifting rope is connected to the conical block. When it is necessary to release the concrete, the workers outside the pouring body can pull the lifting rope to pull the conical block upward, releasing the conical groove, so that the concrete in the storage cylinder can fall to the bottom of the pouring body without causing stratification.

[0023] The storage cylinder 12 and the lifting assembly are located below the support plate 2 and are horizontally suspended below the support frame 4 by the lifting assembly. The support plate 2 has a corresponding injection hole 8 for the storage cylinder 12, which allows concrete to be easily injected into the storage cylinder 12 through the injection hole 8. The bottom of the storage cylinder 12 has a conical groove 14, in which a conical block 15 is placed, and a lifting rope 16 is connected to the conical block 15. The lifting rope 16 passes upward through the support plate 2 and is long enough to allow workers to easily pull the lifting rope 16 from outside the poured body 1. The position where the lifting rope 16 is connected to the conical block 15 is far from the center of the conical block 15, which makes it easier to pull the conical block 15 out of the concrete pressure.

[0024] Adjustment box 3 and limiting component; the storage cylinder 12 is provided with an insertion hole 13, and the support frame 4 is provided with a limiting component corresponding to the insertion hole 13, which is convenient for limiting and fixing the storage cylinder 12 and for pulling the cone block 15; the adjustment box 3 is provided with an adjustment component that can drive the limiting component to rise and fall.

[0025] like Figure 1 , 2 As shown, the lifting assembly includes a take-up and release motor 7, a take-up and release roller 6, and a lifting rope 5. The take-up and release motor 7 is fixedly mounted on the support frame 4, and the take-up and release roller 6 is fixedly sleeved on the output shaft of the take-up and release motor 7. The lifting rope 5 is wound around the take-up and release roller 6, passes through the support frame 4 and the support plate 2, and is fixedly connected to the storage cylinder 12.

[0026] like Figure 3 , 4 As shown, the limiting assembly includes a lifting plate 9 and a fixing rod 11. The lifting plate 9 is slidably disposed within the support frame 4, and the fixing rod 11 is fixedly connected to the lower part of the lifting plate 9, with the fixing rod 11 located directly above the insertion hole 13. A through hole 10 is provided in the lifting plate 9, and the lifting rope 5 passes through the through hole 10, ensuring that the lifting plate 9 does not affect the normal operation of the lifting rope 5. There are two insertion holes 13, and two fixing rods 11 are provided corresponding to the insertion holes 13, which can increase the stability of fixing the storage cylinder 12.

[0027] like Figure 5 As shown, the adjustment assembly includes a rotary motor 18, a lead screw 17, and a slider 19. The rotary motor 18 is mounted on the adjustment box 3. The lead screw 17 is rotatably mounted inside the adjustment box 3 and is fixedly connected to the output shaft of the rotary motor 18. The slider 19 is located inside the adjustment box 3 and is threadedly connected to the lead screw 17. A guide groove communicating with the support frame 4 is provided on the side wall of the adjustment box 3. The slider 19 passes through the guide groove and is fixedly connected to the lifting plate 9. The structure of the motor and lead screw facilitates the lifting control of the lifting plate 9.

[0028] The principle of this utility model

[0029] like Figure 1 , 2 As shown, when using this application, the concrete delivery pipe is connected to the injection hole 8, and the concrete is injected into the storage cylinder 12 through the injection hole 8; as Figure 3 , 4 As shown, since the conical block 15 is located inside the conical groove 14 at this time, it can normally block the conical groove 14, thus preventing concrete from falling off. At the same time, due to the injection of concrete, the pressure of the concrete on the conical block 15 can also increase the stability of the conical block 15 inside the conical groove 14. Start the take-up and discharge motor 7, drive the take-up and discharge roller 6 to rotate, thereby releasing the lifting rope 5, so that the lifting rope 5 drives the storage cylinder 12 to slowly descend until the storage cylinder 12 is close to the bottom of the poured body 1. Once the storage cylinder 12 reaches the designated position and stabilizes, the rotating motor 18 is started, and the slider 19 drives the lifting plate 9 to move downwards until the fixing rod 11 is inserted into the insertion hole 13 to fix the storage cylinder 12. Then, the worker pulls the lifting rope 16 to forcefully pull the conical block 15 upwards out of the conical groove 14, releasing the blockage of the conical groove 14 so that the concrete in the storage cylinder 12 can slide down through the conical groove 14 to the bottom of the pouring body 1. This operation is convenient, not limited by the space of the pouring body 1, and can avoid the stratification phenomenon caused by directly pouring concrete from a high position.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
