Description

Technical Field

[0001] The present invention relates to the technical field of tower construction hoisting safety protection, and in particular to an intelligent tower construction hoisting safety protection method for power construction projects. Background Art

[0002] Power towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are spatial truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 and Q345. The rods are connected with rough bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates and bolts. Individual components such as the tower foot are welded into an assembly by several steel plates.

[0003] At present, the existing technology protects workers who fall from heights by setting up a protective net under the power tower, and also prevents objects falling from heights from injuring workers on the ground below. However, power towers are generally 50 to 60 meters high. If a worker working near the top of the tower falls, there is no guarantee that the falling worker will directly land on the protective net due to the acceleration of gravity and the movement of people. In addition, the falling person may directly deviate and hit the power tower during the fall, causing casualties. In addition, this device does not set a corresponding protective net inside the power tower. If a worker falls inside the power tower, it will directly cause serious injury or death.

[0004] Publication number CN117868537A discloses a protective method and device for the construction of an electric power tower, which includes a load-bearing platform, a telescopic cylinder fixedly connected to the top of the load-bearing platform, a support platform fixedly connected to the output end of the telescopic cylinder, and a moving component arranged on the telescopic cylinder. The telescopic cylinder is started to rise, and the rising movement of the telescopic cylinder drives the inner and outer protective nets to rise and move, always remaining not far below the workers. During the rising process of the telescopic cylinder, the rollers and shafts on the working plate roll along the four corners of the electric power tower, and the moving component moves inward according to the rising height of the telescopic cylinder, supporting the working plate and slowly changing the angle, so that the protective net can continue to rise, avoiding the situation where the workers cannot fall onto the protective net for protection if they fall, and also avoiding the situation where the workers fall over a long distance and directly hit the electric power tower.

[0005] The above technical solution can achieve effective shielding and protection to prevent falling workers from being unprotected and directly colliding with the power tower; however, it cannot protect and detect the installation environment when the tower is installed, and cannot intelligently alarm to remind workers to pay attention, so it needs to be improved.

[0035] S4. Intelligent alarm: Multiple intelligent monitoring components are installed on the automatic protective fence, and the intelligent monitoring equipment is adjusted to achieve comprehensive monitoring of the automatic protective fence to avoid blind spots. The intelligent monitoring equipment can monitor moving objects and record the work clothes of construction workers to determine whether they are staff members. When a moving object climbs over the fence, it can automatically sound an alarm and issue a prompt to the management personnel, thereby protecting the construction site and ensuring that the lifting of components during tower construction can be carried out safely.

[0036] Reference Figure 1-5 The automatic protective fence is composed of three retractable automatic fences. The two adjacent retractable automatic fences are set at right angles. The two retractable automatic fences at both ends are set on one side of the retractable automatic fence in the middle and are set in parallel. Multiple intelligent monitoring components are installed on both sides of the upper ends of the two retractable automatic fences at both ends.

[0037] Reference Figure 2-5 The retractable automatic enclosure includes two bottom plates 18. The corresponding supporting parts can be installed on the upper and lower parts of the bottom plates 18 to facilitate movement and the extension and contraction of the protective net 4. The two bottom plates 18 are rotatably connected to the rotating rods 3. The two rotating rods 3 are fixedly connected to the warning box 1. The warning box 1 is convenient for reminding passers-by that there is construction ahead. One of the bottom plates 18 is fixedly connected to a storage box 5. A winding mechanism is provided in the storage box 5. The winding mechanism includes a protective net 4 provided in the storage box 5. The protective net 4 is made of metal material and can be fully The protective net 4 can be used for protection operations and has excellent protection effects. The protective net 4 plays the role of a fence to divide and block the area. The corresponding area can be effectively fenced off through four retractable automatic fences to prevent people from entering. The three retractable automatic fences can leave an entrance and exit for the entry and exit of corresponding components and equipment. The two ends of the protective net 4 are respectively installed on two rotating rods 3. The storage box 5 is convenient for storing and protecting the protective net 4 to avoid surface rust. The rotating rod 3 is connected to the automatic component and can be rotated to facilitate the winding and unfolding of the protective net 4.

[0038] Reference Figure 2-5 A servo motor 20 is installed in one of the warning boxes 1. The servo motor 20 is connected to external supporting components and is controlled by corresponding control switches to facilitate operation by staff. The end of the output shaft of the servo motor 20 passes through one of the warning boxes 1 and is fixedly connected to the top of one of the rotating rods 3. When storage is required, the servo motor 20 is started, and the end of the output shaft of the servo motor 20 drives the rotating rod 3 connected thereto to rotate smoothly through the coupling, thereby realizing the extension and reeling of the protective net 4.

[0039] Reference Figure 2-5, damping rods 7 are fixedly connected to both sides of the bottom of the base plate 18, and brackets 8 are slidably sleeved on the two damping rods 7. One end of the bracket 8 is fixedly connected to a moving mechanism, and the moving mechanism includes a mounting frame 12 fixedly connected to one end of the bracket 8, a rotating wheel 9 is installed in the mounting frame 12, and a screw rod 11 is provided on one side of the rotating wheel 9. The top of the screw rod 11 is fixedly connected to the mounting frame 12, and a support column 10 is screwed on the screw rod 11. The equipment is effectively moved by the four-part rotating wheel 9. After reaching the specified position, the support column 10 is rotated so that the support column 10 conflicts with the ground to prevent the rotating wheel 9 from moving at will.

[0040] Reference Figure 2-5 , both sides of the bottom of the bottom plate 18 are fixedly connected with the first spring 6, and the two first springs 6 are fixedly sleeved on the two damping rods 7 respectively. If there is a bump during movement, the rotating rod 3 applies pressure to the corresponding bottom plate 18. When the bottom plate 18 is pressed down, the bracket 8 slides on the damping rod 7. The combination of the damping rod 7 and the first spring 6 is used to reduce the vibration amplitude.

[0041] Reference Figure 2-5 The two brackets 8 are fixedly connected by a cross bar 15, and a secondary shock-absorbing mechanism is slidably sleeved on the cross bar 15. The secondary shock-absorbing mechanism includes two sliders 13 slidably sleeved on the cross bar 15 respectively.
