Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of safety protection fences, and in particular to an integrated retractable safety protection fence. Background Art
[0002] When conducting temporary power construction outdoors, safety isolation and protection measures, namely safety protection fences, are often required according to the requirements of construction safety protection specifications to prevent injuries caused by accidental intrusion of unauthorized personnel, such as during foundation pit excavation, pile excavation or other large-scale on-site machinery operations.
[0003] However, existing safety fence structures mainly consist of upright posts and fence panels interlocked between the upright posts, or railings extending horizontally and vertically between the upright posts. For example, the edge protection fence proposed in application number CN201710592652.2 includes upright posts and a protection structure, and the safety protection fence proposed in application number CN201610598041.4 is composed of at least two interconnected fence units, each including a chassis, parallel upright posts, and a fence. These safety protection fences have the following problems during use: First, due to their modular assembly design, the posts and fences are arranged according to the on-site maintenance area, and partial components are often lost during the recycling process, making management inconvenient. Second, the fence dimensions are fixed and cannot be flexibly adjusted according to the actual needs of the work site. Furthermore, the posts serve as the core of the safety protection fence to resist impact forces. Outdoor posts are often directly wedged into the soil for installation, with the bottom of some posts positioned on the soil through the chassis and pins. With this installation method, once an impact occurs, the posts become loose, resulting in poor impact resistance and sustained protection capabilities. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0037] like Figures 1-8As shown, compared with the existing modular assembly design of safety protection fence, the present invention stores the included several railing components 40 and ropes 30 on the storage cylinder 10 through an integrated design. Specifically, the storage cylinder 10 has an inner storage cavity box and an outer storage cavity distributed in an inner and outer layer. The storage cylinder 10 is equipped with a winding component 20, which can wind the rope 30 into the inner storage cavity. At the same time, the rope 30 at least partially extends out of the inner storage cavity. Under normal circumstances, the rope 30 controls the extension length according to the size of the fence area. Several railing components 40 are passed through the rope 30, and several railing components 40 are stored in the outer storage cavity. They can be removed along the rope 30 according to needs. After the main rod body 41 of the removed railing component is positioned, the lock After the pin fitting is wedged into the soil, the main rod body 41 and the rope 30 passed through it slide relative to each other and are locked. During this process, the rope 30 can be tightened to ensure that the rope 30 between adjacent main rod bodies 41 plays an effective hard isolation role. The advantage of this design is that by controlling the relative sliding of the main rod body 41 and the rope 30 through retraction and extension, the distance between adjacent main rod bodies 41 can be flexibly adjusted according to the environmental requirements of the site. At the same time, it can also be tightened and relaxed according to different isolation requirements, that is, corresponding to hard isolation and soft isolation respectively. The integrated safety protection fence can control the length of the fence according to the use requirements, that is, the rope 30 and the railing assembly through which the rope 30 is passed through are stored in layers inside and outside through the storage cylinder 10, which is convenient for retraction, management and transportation and will not be lost.
[0038] Detailed, such as Figure 3 、 Figure 4 As shown, the storage cylinder 10 includes a barrel body 11, which is made of stainless steel and has the functions of corrosion resistance and wear resistance. A turntable 13 is rotatably mounted on the bottom of the barrel body 11. The specific mounting method is to set a ring-shaped card groove on the barrel body 11. The inner edge of the turntable has a protrusion that is inserted into the card groove. A barrel cover 12 is fixedly installed on the top of the barrel body 11. The diameter of the barrel cover 12 is larger than the diameter of the barrel body, and a flange 121 is extended from the outer periphery of the barrel cover 12 toward the turntable 13. A flange 2 131 is extended from the outer periphery of the turntable 13 toward the barrel cover 12. By setting the flange 121 and the flange 2 131, the railing assembly 40 is convenient for retracting and releasing, and it is not easy to slide out. The lid 12 is also provided with a clearance opening 14. The outer side of the barrel body 11 is provided with an outer storage cavity between the barrel lid 12 and the turntable 13, and the inner side of the barrel body 11 is provided with an inner storage cavity. The side wall of the barrel body 11 is provided with a rope opening 16. During the recovery process of the rope 30, the spacing between the railing assemblies 40 becomes smaller and smaller, and finally squeezed together, and all the discs are retracted and placed in the outer storage cavity through the passage of the rope 30, that is, stored between the barrel lid 12 and the turntable 13 through the clearance opening 14. The purpose of rotating the turntable 13 is that when the railing assembly 40 is unloaded outward, the turntable 13 can directly rotate to push the outermost railing assembly 40 to the clearance opening 14, which is convenient to take out and avoids the time-consuming and labor-intensive pulling.
[0039] Further, in detail, under normal circumstances, the height of the fence is at least double-layered, and the height of the railing on the upper layer is not less than 1.2 meters. The ropes 30 provided in this embodiment are two groups, so the barrel body 11 is divided into two inner storage chambers by the partition plate 15. The winding assembly 20 includes a rotating shaft 21 that passes through the two inner storage chambers. The top of the rotating shaft 21 is connected to the handle 23 through the connecting rod 22. There are two ropes 30, one end of the rope 30 is connected to the rotating shaft 21, and the other end passes through the rope mouth 16. The rope 30 is controlled to be recovered to the inner storage chamber by rotating the handle 23.
[0040] like Figure 1 、 Figure 2 、 Figure 5-Figure 8 , two rope grooves 412 are provided on the main rod body 41 for passing two ropes 30, and the rope groove 412 passes through the main rod body 41 horizontally, and the rope 30 passes through the rope groove 412. The main rod body 41 is also provided with two slide grooves 411, and the slide groove 411 extends axially along the main rod body 41. The two slide grooves 411 are located on both sides of the rope groove 412, and the slide groove 411 is at least partially connected to the rope groove 412. The top of the slide groove 411 passes through the top surface of the main rod body 41, and the lock pin accessories include two pin rods 42. The pin rod 42 can be rotatably inserted in the slide groove 411. The top of the pin rod 42 is rotatably connected to the disk body 43. At the same time, one side of the top of the pin rod 42 is fixedly connected to the driving rod 422. The pin rods 42 below the driving rod 422 are circumferentially spaced 90 degrees apart. A clearance groove 421 is provided on the side wall. The height of the top of the clearance groove 421 is greater than the rope groove 412, and the height of the bottom of the clearance groove 421 is less than the rope groove 412, so that the pin rod 42 can move up and down and cover the rope groove 412. When the clearance groove 421 faces the rope groove 412, the rope 30 can pass through the rope groove 412 freely. When the clearance groove 421 is away from the rope groove 412, the side wall of the pin rod 42 squeezes the rope 30. Under normal circumstances, the clearance groove 421 faces the rope groove 412, that is, the rope 30 can pass through the rope groove 412 freely. When the installation point is determined, the bottom end of the pin rod 42 can be wedged into the soil by knocking on the disk body 43, and then the pin rod 42 is rotated so that the side wall of the pin rod 42 squeezes the rope 30 to clamp and fix the rope 30.
[0041] In detail, the bottom end of the main rod body 41 is also concavely provided with a accommodating cavity 413, and the bottom ends of the two slide grooves 411 are connected to the accommodating cavity 413. The bottom ends of the two pin rods 42 are provided with rotatable engaging teeth 423. In the engaged state, the teeth 423 can be moved up and retracted into the accommodating cavity 413 along with the pin rod 42. In the engaged state, that is, by knocking the disc body 43, the bottom ends of the two pin rods 42 are wedged into the soil. The engaged teeth 423 and the bottom ends of the two pin rods 42 are combined into a solid body with a bottom tip, which is convenient for wedging into the soil as a whole. After wedging, in the process of rotating the pin rod 42, the engaged teeth 423 are separated, and they are rotated around the axis of the pin rod 42 as the center of the circle, and gradually inserted into the soil. The rotation angle of the pin rod 42 is 180 degrees, which finally achieves the purpose of double locking with the rope 30 and the soil, thereby increasing the stability of the main rod body 41.
[0042] like Figure 4 As shown, the outer end of the rope 30 is fixedly connected to a ball head 31, and the diameter of the ball head 31 is larger than the width of the rope groove 412, so that all the main rods 41 can be passed through to prevent them from falling off or being lost.
[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
