Description

Technical Field

[0001] The invention relates to the field of construction steel-wood keel processing, in particular to a construction steel-wood keel recovery and preparation system. Background Art

[0002] Concrete is widely used in construction projects. In the construction process of cast-in-place concrete structures, keels and sub-keels play a key role in supporting and maintaining the shape of concrete, enhancing structural strength and stability, and the amount of on-site use is extremely large. Taking residential projects, which are the most convenient for turnover and multiple turnover, as an example, about 100,000 to 140,000 meters of keels are used for construction of every 10,000 square meters of building area, and the general specifications reach dozens of types. The amount of keels used in other types of projects is generally higher than this amount. At present, the keels used in the concrete support system of the construction industry are mainly: traditional solid wood keels, steel-wood keels, composite material keels, etc. Among them, steel-wood keels are more and more widely used due to their excellent comprehensive performance and compliance with environmental protection and green concepts. Steel-wood keels can be found in patent application number CN202021961453.8, and the patent name is a patent content of a steel-wood keel for construction.

[0003] During the implementation of the project, the keel is usually combined with iron nails and formwork. It bears a large load and directly contacts the concrete during the concrete pouring process. After the concrete is poured, the built keel structure must be dismantled for turnover. The dismantled keels often have practical problems such as cement wrapping, nail attachment, and keel bending, which require preparation and maintenance. At the same time, the dismantled keels are often mixed with various models. In the later reuse of inventory, transportation and other links, sorting and classification are required. At present, the sorting, nail removal, straightening, sorting, and transportation of keels mainly rely on manual labor. The method of manually comparing the lines drawn on the ground with the eyes is prone to errors, resulting in classification errors. In addition, the steel-wood keel is composed of a steel outer keel and a wooden inner keel that runs through the outer keel. The overall weight is large, and the process of manual recycling is labor-intensive, low work efficiency, and high labor costs. Problems are very prominent. In addition, the potential dangers such as residual steel nails, iron sheet warping, and wooden thorns on the steel-wood keel can easily cause workers to be injured during operation and transportation.

The two ends of the transmission unit are connected with the lifting unit and the sorting mechanism respectively. The photoelectric sensor is arranged on the transmission unit. The photoelectric sensor is used to sense the steel-wood keel of the building and sense and detect the two ends of the steel-wood keel of the building. The built-in algorithm module calculates the length value of the steel-wood keel of the building in real time through the conveying speed of the transmission unit and the sensing time of the photoelectric sensor, which is used for classification and sorting by the subsequent sorting mechanism. The time interval for the two ends of the building steel-wood keel to pass through the photoelectric sensor is time T, and the transmission unit drives the running speed of the building steel-wood keel to be V: L = V * T; Then the length L of the building steel-wood keel is obtained.

7. A building steel-wood keel recovery and preparation system according to claim 6, characterized in that: The sorting mechanism includes at least one group of sorting components, and the sorting components include a sorting line body and at least one group of sorting frames. The sorting line body is connected to the tail end of the transmission unit, and the sorting frame is arranged on the side of the sorting line body. The sorting frame is used to collect the construction steel-wood keels transported by the sorting line body.

8. A building steel-wood keel recovery and preparation system according to claim 7, characterized in that: The sorting frame includes a frame body, a cylinder unit and a plurality of groups of sorting units arranged in horizontal layers. The cylinder unit is arranged on the upper side of the frame body. The fixing part of the cylinder unit is fixedly connected to the frame body. The free end of the cylinder unit is directly opposite to the steel-wood building keel on the sorting line. The sorting unit includes an electric guide plate, a gathering line and a storage table. The electric guide plate and the storage table are respectively arranged at both ends of the gathering line.

9. A building steel-wood keel recovery and preparation system according to claim 1, characterized in that: The processing steps include: Step 1, the feeding assembly conveys the steel-wood keels one by one along the X direction, the conveying line conveys the steel-wood keels along the Y direction perpendicular to the X direction, and the nail pulling assembly is used to remove the steel nails on the steel-wood keels; Step 2, the plurality of straightening roller groups of the straightening mechanism cooperate to straighten the steel-wood keel of the building; Step 3, the cleaning mechanism includes a cover body, a plurality of groups of mutually orthogonal wire roller groups and a cleaning bin, the plurality of groups of wire roller groups cooperate to clean the surface of the steel-wood keel of the building, and the cleaning bin is used to collect garbage after the surface treatment of the steel-wood keel of the building; Step 4: The re-inspection conveying platform conveys the steel-wood keels one by one along the conveying direction perpendicular to the conveying line body, and the lifting assembly drives the steel-wood keels to move up to the measuring assembly. The measuring assembly conveys the steel-wood keels to the sorting mechanism and measures the length data of the steel-wood keels; Step 5: The sorting mechanism is used to sort and temporarily store the steel-wood keels of the building with measured length data.
