[0017] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0018] Example 1

[0019] like Figure 1-4 As shown, a self-protective tower type concrete distributor lattice base for an elevator shaft comprises a lattice base body 1, and four elevator shaft protection plates 2 are respectively hinged around the lattice base body 1, and the outer sides of the four elevator shaft protection plates 2 are respectively fixedly connected to one end of a steel wire rope 5 in the middle of the lattice base body 1, and the other end of the steel wire rope 5 is connected to the lattice base body 1; when the lattice base body 1 is used, the four elevator shaft protection plates 2 are sequentially connected end to end on a horizontal plane in the elevator shaft, and the steel wire rope 5 is pulled upward, and the four elevator shaft protection plates 2 are folded toward the lattice base body 1 to prevent the elevator shaft protection plates 2 from colliding with the poured concrete structure. The device is low-cost and easy to use, and solves the problem that when the tower type concrete distributor is hoisted due to construction, in order to reduce the potential safety hazards of construction, protection is set up in the elevator shaft, but the installation and removal of each floor consumes a lot of manpower and material resources, and has good protection effect and practicality.

[0020] In order to save effort in pulling the steel wire rope 5 and conveniently operate four elevator shaft protection plates 2 at the same time, Figure 2 As shown, four fixed pulleys 4 are respectively arranged above the four elevator shaft protection plates 2 in the middle of the lattice base body 1, and the two opposite elevator shaft protection plates 2 are connected by a steel wire rope 5. After the steel wire rope 5 passes through the two opposite fixed pulleys 4, the two ends of the steel wire rope 5 are respectively fixedly connected to the two opposite elevator shaft protection plates 2. The two steel wire ropes 5 of the four elevator shaft protection plates 2 are cross-crossed, and the intersection of the two steel wire ropes 5 is connected to the pull rope 9, and the other end of the pull rope 9 is connected to the lattice base body 1. When the elevator shaft protection plate 2 needs to be folded, it is only necessary to operate the pull rope 9 to move the middle part of the two steel wire ropes downward, that is, to exert an upward pulling force on the elevator shaft protection plate 2 at the same time, and the four elevator shaft protection plates 2 are folded at the same time, and the use of the fixed pulley 5 saves time and effort. Similarly, when the lattice base is used, the pull rope 9 is loosened, the middle part of the two steel wire ropes 5 moves upward, and the elevator shaft protection plates 2 are lowered at both ends.

[0021] Furthermore, the other end of the pull rope 9 is connected to the metal fixing ring 6, which is buckled on the fixing ear block 7. At least two fixing ear blocks 7 are welded on the lattice base body 1 at a set distance up and down, making it more convenient to fix the position of the elevator shaft protective plate 2.

[0022] In order to ensure that the pull rope 9 exerts a vertical downward pulling force on the steel wire rope 5, and to operate four elevator shaft protection plates 2 at the same time, and to facilitate the operation of the staff, the other end of the pull rope 9 is vertically passed downward around the guide pulley 10 and then connected to the lattice base body 1 upward.

[0023] Furthermore, the outer sides of the four columns of the lattice base body 1 are respectively hinged with the elevator shaft protection plate 2 using metal hinges 3 to ensure that the elevator shaft protection plate 2 can be flexibly unfolded or folded.

[0024] The outside of the four columns of the lattice base body 1 are respectively welded with inverted L-shaped support ear blocks 8 below the elevator shaft protective plate 2. The top plate of the support ear block 8 is in contact with the bottom surface of the horizontal elevator shaft protective plate 2, which can ensure the supporting effect of the elevator shaft protective plate and prevent operators from stepping on it.

[0025] Instructions for use: When the lattice base is used, the pull rope 9 is buckled on the fixed ear block 7 located below through the metal fixing ring 6, the wire rope 5 is naturally tightened, and the four elevator shaft protection plates 2 are horizontally unfolded and located on the same plane, and the bottom is in contact with the supporting ear block 8; when the lattice base 1 needs to be lifted, the metal fixing ring 6 is buckled on the fixed ear block 7 located at the upper part, and the pull rope 9 has a downward pulling force on the wire rope 5, so that the two ends of the wire rope 5 pull the elevator shaft protection 2 upward, and the elevator shaft protection plate 2 folds inward to prevent the protection plate from colliding with the poured concrete structure.

[0026] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
