[0027] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the utility model, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that according to the specific implementation situation, a better connection structure can be formed by adding or reducing connection accessories. For example, fixed connection / fixed installation can be selected according to the needs of screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods. For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.

[0028] See also Figure 1-8The preferred embodiment of the utility model provides a shaft opening protection device, including a protection body 1, a first clamping piece 2 and a second clamping piece 3. The first clamping piece 2 and the second clamping piece 3 are both arranged in a trumpet shape. A plurality of through holes 11 are arranged on the protection body 1. The through holes 11 are arranged in a square shape. Each through hole 11 is correspondingly connected with a first clamping piece 2, and the first clamping piece 2 is connected to the through hole 11. The second clamping piece 3 is used for clamping with a scaffolding steel pipe 4, and the end of the second clamping piece 3 with a smaller cross-section faces the upper end of the scaffolding steel pipe 4, and the first clamping piece 2 is sleeved on the second clamping piece 3. When in use, the second clamping member 3 is clamped with the scaffolding steel pipe 4, and the scaffolding steel pipe 4 passes through the through hole 11 and the first clamping member 2, and the first clamping member 2 is sleeved with the second clamping member 3, so that the protective body 1 is connected to the second clamping member 3 through the first clamping member 2. Since the first clamping member 2 and the second clamping member 3 are both set to be trumpet-shaped, and the end of the second clamping member 3 with a smaller cross section faces the upper end of the scaffolding steel pipe 4, when a heavy object falls into the protective body 1, the second clamping member 3 is subjected to a downward force, and the second clamping member 3 and the scaffolding steel pipe 4 are clamped more tightly, thereby improving the protective effect. When construction is required at another location, the first clamping member 2 is first removed from the second clamping member 3 upward along the scaffolding steel pipe 4, so as to separate the protective body 1 from the second clamping member 3, and then the protective body 1 is moved to a designated position, and the second clamping member 3 is fixed at the designated position, and finally the first clamping member 2 is sleeved with the second clamping member 3, which is simple to operate, convenient for construction, and can be reused, saving costs.

[0029] The second clamping member 3 includes a trumpet-shaped clamping body 31 and a clamping hoop 32. The clamping hoop 32 is sleeved on the outer peripheral surface of the clamping body 31. The clamping body 31 is hollow, and a notch 311 is provided on one side of the clamping body 31. The notch 311 extends to both ends of the clamping body 31. When in use, as the clamping hoop 32 is tightened, the notch 311 gradually becomes smaller. The greater the friction between the clamping body 31 and the scaffolding steel pipe 4, the tighter the two are clamped, thereby the better the load-bearing effect of the protective body 1.

[0030] The clamping body 31 is made of wood, and the rough surface of the wood helps to increase the friction between the clamping body 31 and the scaffolding steel pipe 4; the clamp 32 is made of steel, which is strong and durable.

[0031] One end of the clamping body 31 facing the upper end of the scaffolding steel pipe 4 is chamfered to facilitate the first clamping component 2 to be sleeved on the clamping body 31 and to facilitate the assembly of the two.

[0032] The protection body 1 includes a protection frame 12 and a protection net 13. The protection net 13 is arranged on the protection frame 12. The protection frame 12 is connected by a plurality of connecting rods 131. The through hole 11 is connected with the mesh of the protection net 13, so that the scaffolding steel pipe 4 can pass through the through hole 11. The protection frame 12 can provide support and has good load-bearing capacity. The protection net 13 is used to prevent people or objects from falling into the gap of the protection frame 12, thereby further improving safety.

[0033] In this embodiment, the connecting rod 131 is made of steel, and the protective net 13 is made of iron net, which is strong and durable.

[0034] In this embodiment, the connecting rods 131 are welded to each other to form the protective frame 12. The welding method is easy to operate, and the connecting rods 131 are firmly connected after welding.

[0035] A hook 121 is connected to the protection frame 12 to facilitate lifting the protection body 1. During operation, a tower crane can be used to lift it up through the hook 121 and then move it to a designated position.

[0036] There are four hooks 121 arranged in a square shape. After the tower crane hooks the four hooks 121, it is beneficial to maintain balance and enhance the safety of construction.

[0037] The through hole 11 is enclosed by the connecting rod 131 . The through hole 11 is square, which is easy to manufacture and does not require special drilling or drilling equipment, which is conducive to cost saving.

[0038] One end of the first clamping member 2 is located in the through hole 11 and is welded to the connecting rod 131 surrounding the through hole 11 . The first clamping member 2 and the connecting rod 131 are firmly connected to prevent the first clamping member 2 from being separated from the protective body 1 .

[0039] In this embodiment, the end of the first clamping component 2 with a smaller cross-section is welded to the connecting rod 131. When in use, the first clamping component 2 is located below the protective body 1 to prevent the first clamping component 2 from causing accidental injury to a person falling into the protective body 1, thereby ensuring safety in use.

[0040] The first clamping member 2 is formed by enclosing a steel plate, which is easy to manufacture, and the steel plate is strong and durable.

[0041] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
