Description

Technical Field

[0001] This utility model relates to the field of building material lifting, specifically a miniature material vertical transport and lifting device. Background Technology

[0002] Currently, in urban old residential area renovation projects, the existing buildings are mostly 4-5 story brick-concrete structures. In the renovation of exterior walls and roofs, the vertical transportation of materials is a key factor affecting the construction period.

[0003] Due to the limited space, crisscrossing overhead cables and wires, narrow building spacing, steep slopes, numerous illegal structures, and time constraints, it is impossible to demolish illegal structures before renovation in some areas. Therefore, vertical transportation of materials is necessary. However, the site lacks the conditions for setting up vertical transportation facilities such as material hoists. In addition, the slope and operating space of most sites do not allow for the use of wheeled cranes and material conveyors. Furthermore, manual vertical transportation is costly and will limit the vertical transportation of micro-materials and reduce efficiency. To address these issues, we propose a vertical transportation and lifting device for micro-materials. Utility Model Content

Supporting longitudinal rods 13 are fixedly connected to the sides of the two sets of main fixing cylinders 11 that are close to each other. By setting the fixing sleeve 7, fixing screw 5, and locking nut 6, the connecting plate 3 can be firmly fixed above the supporting crossbar 1 to prevent displacement during lifting. By using the arc-shaped fixing plate 17, locking screw 20, and threaded groove 18, the connection between the supporting crossbar 1 and the supporting plate 2 can be strengthened to ensure structural stability.

[0023] In this embodiment, an arc-shaped fixing plate 17 is provided above each of the two supporting plates 2.

[0025] Working principle: First, the support crossbar 1 is fixed above the support carrier plate 2 by the arc-shaped fixing plate 17, locking screw 20 and threaded groove 18, so that the arc-shaped concave hole 26 fits with the support crossbar 1, ensuring the stability of the support crossbar 1. Then, the main fixing cylinder 11 is connected and fixed to the threaded groove 23 of the upper support column 10 by fixing screw 25.
