Description

Technical Field

[0001] The present application relates to the field of carrying frames, and in particular to a building carrying frame. Background Art

[0002] A building is a place where people carry out production, life, residence or other activities, such as industrial buildings, civil buildings, and agricultural buildings. In building construction, because some high-position operators cannot complete the work, a building carrying frame is needed for cooperation.

[0003] Chinese Patent with the authorized publication number CN207063468U discloses a building carrying frame, which includes a platform, feet for supporting the platform. An elevating platform is further arranged on the platform, and a plurality of connecting rings are arranged on the elevating platform. A connecting rope is arranged on the plurality of connecting rings, and a rotating cylinder is fixed on the side of the connecting rope away from the connecting ring. When in use, building materials are placed in the elevating platform, and then the elevating platform is driven to rise by the connecting rope.

[0004] By rotating the handle, the connecting rope can be driven to move up and down, so as to drive the elevating platform to move up and down. People can put tools into the elevating platform for transportation without having to keep going up and down the platform to pick up tools. However, the connecting rope bears a large gravity. After long-term use, the connecting rope is easily worn. When the connecting rope breaks, the elevating platform will directly fall, and the tools are likely to fly out, easily causing safety accidents. Summary of the Invention

When the pulling rope 5 breaks, the second spring 616 applies a downward force to the rotating shaft 42 in order to restore its deformation. The rotating shaft 42 and the rotating wheel 43 move downward under the action of gravity, causing the first spring 614 to contract, the sliding column 613 to slide downward, the first rack 641 to slide downward, the first gear 642 to rotate, the second rack 643 to slide upward to drive the pin shaft 621 to move upward and disengage from the limiting hole 661. The torsion spring 68 restores its deformation and drives the roller 66 to rotate and release the rope through the limiting rope 69. The sealing plate 67 covers the notch of the accommodating groove 33, the driving column 672 extends into the driving groove 36, the abutting column 71 moves downward interactively, the third spring 76 contracts, the third rack 73 slides downward, the second gear 75 rotates, and the friction block 77 rotates to make the friction block 77 abut against the groove wall of the guiding groove 121 to play a buffering role.

[0056] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
