Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a height-reducing guide for a sky pump. Background Technology

[0002] In concrete pouring operations of large-scale construction projects, especially in high-rise buildings and large infrastructure projects, concrete boom pumps are widely used due to their wide coverage and high efficiency. However, when there is a large drop between the outlet of the hose at the end of the boom pump and the pouring surface (such as deep foundations and high-rise floor slabs), the excessive free fall height of the concrete can bring significant technical challenges. For example, the high drop height leads to excessively fast concrete falling speed and high impact force, which can easily disrupt the homogeneity of the various components (aggregate, mortar, water) within the concrete, causing severe segregation. Segregation can significantly reduce the final strength, durability, and appearance quality of the concrete, creating structural safety hazards or appearance defects. Moreover, the high-speed falling concrete directly impacts the reinforcing steel, formwork, or the already poured concrete surface, not only causing material splashing and waste and environmental pollution, but also potentially damaging the reinforcing steel cover, formwork, and even causing coarse aggregate to break, further affecting the concrete performance.

[0003] Currently, there are some buffer devices or chutes on the market that have complex structures and are inconvenient to assemble and disassemble. For example, many devices are large in size and have many parts, resulting in low efficiency in installation, disassembly and transportation, making it difficult to meet the needs of rapid relocation of the boom pump and different work sites. Utility Model Content

[0004] The purpose of this utility model is to provide a height reduction guide for concrete pumping construction, especially for high-rise or large-drop concrete pouring scenarios.

[0005] This utility model is achieved through the following measures: A height reduction guide for a concrete pump, characterized in that it includes an upper steel pipe installed at the end of the pump wall pipe, a diverter installed at the lower end of the upper steel pipe, and a conical barrel installed around the diverter. The conical barrel can be a conventional concrete pouring conical barrel with a diameter of 1m, serving as a concrete transfer and buffer component to reduce the impact of vertical drop on the homogeneity of the concrete. A matching lower steel pipe is installed at the lower outlet of the conical barrel, and a water hose is connected to the lower steel pipe through a flange, which can be flexibly lengthened according to the pouring height requirements to further control the concrete outlet drop. The diverter includes a main pipe connected to the upper steel pipe. The lower end of the main pipe is closed and several sets of discharge pipes are evenly arranged around its perimeter. Concrete enters the upper steel pipe, then passes through the main pipe and several discharge pipes in sequence into the conical barrel, and finally flows out through the lower steel pipe. The upper steel pipe is selected with a diameter of φ160, which can be matched with the diameter of conventional pump pipes.

[0006] The specific features of this utility model also include: Both the upper and lower steel pipes are equipped with matching check valves. In this embodiment, ordinary check valves are used and the specifications of the check valves are matched with the steel pipes to ensure pipeline sealing and pressure compatibility. The discharge pipe consists of four sets and is connected to the main pipe via a flange structure, which facilitates disassembly and maintenance. The discharge pipe is a funnel-shaped structure with an upper length greater than the lower length and a lower inclination angle greater than the upper inclination angle, which can effectively buffer the concrete flow rate.

[0007] The distance between the outlet end of the discharge pipe and the inner wall of the conical barrel is not less than 10cm to avoid interference during concrete transportation. The top of the conical bucket is at least 10cm higher than the discharge pipe to prevent concrete from overflowing.

[0008] Several sets of steel plates are uniformly welded around the periphery of the main pipe. The other end of each steel plate is welded to the upper end of the conical barrel, thereby fixing the conical barrel to the distributor.

[0009] Several sets of steel plates II are evenly arranged around the periphery of the main pipe. A vertical plate I is provided at the free end of the steel plate II. Several sets of vertical plates II that cooperate with the vertical plate I are evenly welded around the upper end of the conical barrel. The vertical plate I and the corresponding vertical plate II are connected and fixed by bolts and nuts, thereby fixing the conical barrel to the distributor. At the same time, the bolt and nut structure can facilitate the disassembly and maintenance of the conical barrel.

[0010] The second steel plate is welded to the periphery of the main pipe.

[0011] The upper steel pipe has a threaded section with external threads on its outer periphery, which is close to the main pipe. A locking ring is provided around the threaded section. Several sets of grooves that mate with the second steel plate are evenly arranged around the circumference of the threaded section. The inner side of the second steel plate away from the first vertical plate has an insert plate that mates with the groove. The outer side of the insert plate away from the groove is set with an arc-shaped structure that mates with the outer periphery of the upper steel pipe. After the insert plate is inserted into the groove, it is locked and fixed by the locking ring. Specifically, when the insert plate is inserted, the locking ring is rotated downward to cover the insert plate, thereby fixing the second steel plate. This structure allows for easy disassembly of the second steel plate, thus facilitating subsequent equipment maintenance.

[0012] An insert block is provided in the center of the groove, and a slot is provided on the insert plate to cooperate with the insert block. The insert block is placed in the slot. Due to the thickness limitation of the upper steel pipe, the groove depth is not very deep. In order to facilitate the installation of the second steel plate, a structure is further provided in which the insert block and the slot cooperate. In this way, several sets of the second steel plates can be installed smoothly and locked and fixed by the locking ring.

[0013] The beneficial effects of this utility model are as follows: This invention, through multi-level buffering and diversion design, is adapted to the operation scenario of the concrete pump, effectively reduces the concrete pouring height, reduces the risk of segregation, and is easy to assemble and disassemble with strong adaptability.
