Description

Technical Field

[0001] This invention belongs to the field of measurement, specifically relating to a triangular positioning tool for a rectangular chute connector in grain storage and its usage method. Background Technology

[0002] In the construction of grain storage projects, the installation of chutes is crucial for ensuring efficient grain transfer and storage. Due to the complex building structure, compact equipment layout, and irregular site shape, the ends of the chutes often exhibit twisting angles and non-parallelism. This necessitates the fabrication of irregularly shaped chutes using multiple triangular welds to complete the connection points. Extensive measurement work is required before fabrication. Traditionally, measuring tapes are used to measure each side, recording the dimensions, and then marking lines on a steel plate with a ruler before cutting and welding each section. This traditional method is labor-intensive, involves multiple people working together, increases costs, and is inefficient. Furthermore, the width of the tape measure and the high error rate due to repeated manual measurements result in measurements that are either too large or too small compared to the actual values. This often leads to gaps in the weld or secondary cutting during subsequent welding, slowing down construction speed, affecting the chute installation progress, and impacting the project schedule.

Detailed Implementation

[0013] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

Figure 2 The positioning component includes short timber 1-2, a long timber 1-1 perpendicularly connected to the short timber, and a sliding positioning element 1-5 disposed on the long timber. The length of the long timber is at least 100mm longer than the single-side length of the rectangular port of the larger chute 3. Long, narrow grooves 1-4 are provided in the middle of both sides for mounting the sliding buckles of the aluminum alloy sliding positioning element 1-5. The length of the short timber can be controlled to 150mm. The chute port size of the larger chute is 300-500mm, so the groove opening size is approximately 250mm.

It is necessary to ensure that the hole of the second positioning peep screw is aligned with the bottom of the long (short) timber to ensure subsequent measurement accuracy. At the right angle where the short and long timbers intersect, a cylindrical groove 1-3-2 is carved out. The diameter of the groove is larger than the size of the old measuring tape body, and space is reserved for winding ultra-high molecular weight polyethylene thread as a thin rope. A central post 1-3-3 is set in the middle of the cylindrical groove 1-3-2 to hold the measuring tape body 1-3-1.
