Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a safety protection device for construction engineering management. Background Art

[0002] In the process of construction project management, some safety protection devices are usually used to ensure the safety of construction. For example, the patent with announcement number CN216197164U discloses a safety protection railing for construction project management, including a mounting groove, an adjustment structure and a connecting structure. A two-way threaded rod is installed on one side of the mounting groove through a rotating shaft, a knob is installed on one end of the two-way threaded rod, and two threaded blocks are connected to the outer wall of the two-way threaded rod through threads, and the top of the threaded block is respectively installed with a first support railing and a second support railing, and fixing rods are installed at the upper and lower ends of the first support railing away from the second support railing, and a mounting ring is installed on one side of the fixing rod, and the connecting structure is located at the upper and lower ends of the second support railing away from the first support railing.

[0003] The above patent adjusts the length of the guardrail by moving the first support rail and the second support rail away from each other and driving the protective net to continuously rotate out from the outer wall of the mounting roller. However, in actual use, the above patent uses a torsion spring to fix and pull the protective net. When a large external force is applied to the protective net, the torsion spring cannot prevent the protective net from being pulled out, resulting in the protective net being unable to achieve its due protective effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and safety protection devices for construction project management are provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a safety protection device for construction project management to solve the problems existing in the above-mentioned background technology.

[0007] Furthermore, the rotating shaft and the inner wall of the left column are rotatably connected via a bearing, and the bearing improves the smoothness of the rotation of the rotating shaft in the device, thereby improving the adjustment speed of the device by the staff.

[0008] Furthermore, a partition is provided between the gear and the protective net, and the partition is fixedly mounted on the inner wall of the left column. The partition is penetrated by a rotating shaft, and the position between the protective net and the gear is limited by the partition to prevent the protective net from being entangled on the gear when loose, thereby affecting the normal use of the device.

[0009] Furthermore, a number of winding rods are evenly and straightly installed on the same side of the outer rod and the sliding rod of the telescopic rod, a sliding groove corresponding to the winding rod on the sliding rod is opened on one side of the outer rod, and two limit blocks are fixedly installed on one side of the winding rod, and a number of pull ropes are evenly installed on the upper and lower ends of the protective net in a straight line, and the pull ropes are movably wound around the outside of the winding rod at corresponding positions. After the length of the protective net is adjusted, the pull ropes can be wound around the outside of the winding rod to fix and limit the upper and lower end positions of the protective net, thereby improving the protection effect of the device.

[0010] Furthermore, a limit block is fixedly installed on the outside of the threaded rod, and the limit block is movably arranged inside the left column. The movement of the threaded rod is limited by the limit block to prevent the threaded rod from falling off and being lost on the device after the staff excessively rotates the threaded rod.

[0011] Furthermore, the outer sides of the first rotating block and the second rotating block are both provided with anti-skid grooves. The anti-skid grooves provided on the outer sides of the first rotating block and the second rotating block ensure that when the staff rotates the first rotating block and the second rotating block, the contact of their hands has better friction.
