Description

Technical Field

[0001] This utility model relates to a substation isolation fence, and more particularly to a safety isolation fence that prevents crossing and tipping. Background Technology

[0002] When working around live equipment in a substation, installing isolation fences is a common safety measure to ensure that personnel do not wander into the wrong areas and work within a safe range. According to current safety management requirements, in addition to installing isolation fences at the work site, corresponding work passages should also be installed to ensure that personnel do not wander into the wrong areas. This requires that the setting of safety fences be reasonable.

[0003] Authorization notice number CN 221568096 U discloses a safety isolation fence, including a first post and a second post. Fixing plates are fixedly installed on both sides of the lower end of the first and second posts. A first crossbar and a second crossbar are installed between the first and second posts. A plug is installed between the first and second crossbars at a distance. A limit screw passes through the middle of the first and second posts. When two adjacent fences need to be connected and fixed, the positioning plug on one side of the first post of the first fence is inserted into the connecting slot on one side of the second post of the second fence. At this time, the positioning hole in the middle of the positioning plug aligns with the through holes at both ends of the connecting slot. Finally, the limit screw can be inserted through to prevent the positioning plug from separating from the connecting slot on its own.

[0004] The above-mentioned patented technology has some shortcomings: 1. The connection and disassembly are cumbersome, requiring the removal of the limiting screw, which is relatively long and inconvenient to remove; 2. There are no locks between adjacent fences, which can be opened at will and cannot prevent accidental entry; 3. Each fence is of fixed length, making it difficult to form a suitable protective area. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a safety isolation fence that is reasonably designed, prevents accidental entry into the fence, and is easy to operate, thus preventing crossing and tipping.

[0006] The technical solution of this utility model is:

[0007] A safety barrier to prevent crossing and tipping includes side frames at both ends and telescopic bars in the middle. The telescopic bars are staggered and connected by hinge shafts. The side frames are inverted T-shaped structures, consisting of bottom legs and upper vertical bars. Two wheel assemblies are spaced apart on the inner side of the bottom legs, and magnetic locks are provided on the outer side of the vertical bars.

[0008] Furthermore: the walking wheel is an adjustable structure, including a walking wheel, a wheel frame, a support plate and a screw. The support plate is set on the side frame and has a through hole. The screw passes through the through hole and is positioned by a fixing nut and a locking nut. The lower end of the screw is provided with a fixing seat, which is rotatably connected to the upper end of the wheel frame. The walking wheel is mounted on the wheel frame.

[0009] Furthermore, the support plate is an L-shaped structure or a straight structure, one end of the support plate is connected to the bottom support leg of the side support frame, and the two support plates are symmetrically arranged relative to the vertical support rod.

[0010] Furthermore, the weight of the bottom support leg is greater than the weight of the vertical support, and the center of gravity of the entire safety isolation fence is lower than half of its height, increasing stability.

[0011] The beneficial effects of this utility model are:

[0012] 1. Each section of this utility model uses a telescopic fence rod, which can change the overall length. Adjacent fence sections are locked with magnetic locks, and only operators with a decoder can unlock and enter, effectively preventing personnel from accidentally entering and improving the protection effect.

[0013] 2. This utility model uses height-adjustable wheels. When moving, the wheels are in contact with the ground, making it easy to move. After the fence is formed, the wheels are separated from the ground, restricting the movement of the fence and effectively preventing the fence from being moved accidentally.

[0014] 3. This utility model uses a screw, a fixing nut, and a locking nut in combination, which makes adjustment convenient and operation easy.

[0015] 4. The lower part of the side frame of this utility model is heavier than the upper part, which makes the center of gravity lower, increases the overall stability, and prevents it from being blown over by the wind.

[0016] 5. This utility model has a reasonable design, prevents accidental entry into the fence, is easy to operate, is easy to promote and implement, and has good economic benefits. Attached Figure Description

[0019] Figure 3 for Figure 1 Enlarged view of point A in the middle. Detailed Implementation

[0020] Example: See Figure 1 -- Figure 3 In the diagram, 1-telescopic fence, 2-side support frame, 3-magnetic lock, 4-wheel assembly, 5-hinged shaft, 41-screw, 42-fixing nut, 43-locking nut, 44-wheel, 45-wheel frame, 46-fixed seat, 47-support plate.

[0021] A safety barrier to prevent crossing and tipping includes side frames 2 at both ends and telescopic bars 1 in the middle. The telescopic bars 1 are staggered and connected by hinge shafts 5. The side frames 2 are inverted T-shaped structures, consisting of bottom legs and upper vertical bars. Two wheels 4 are spaced apart on the inner side of the bottom legs, and magnetic locks 3 are installed on the outer side of the vertical bars.

[0022] Preferred solution: The walking wheel assembly 4 is a height-adjustable structure, including walking wheels 44, wheel frames 45, support plates 47 and screws 41. The support plate 47 is mounted on the side frame 2 and has a through hole. The screw 41 passes through the through hole and is positioned by fixing nuts 42 and locking nuts 43. The lower end of the screw 41 is provided with a fixing seat 46, which is rotatably connected to the upper end of the wheel frame 45. The walking wheels 44 are mounted on the wheel frame 45.

[0023] Preferred solution: The support plate 47 is an L-shaped structure or a straight structure (the shape of the support plate 47 is determined according to the size of the traveling wheel 44. If the traveling wheel 44 is large, an L-shaped structure is adopted to facilitate connection with the bottom support leg. Otherwise, a straight structure is adopted). One end of the support plate 47 is connected to the bottom support leg of the side frame 2. Furthermore, the two support plates 47 are symmetrically arranged with respect to the vertical support rod.

[0024] Preferred solution: The weight of the bottom support legs is greater than the weight of the vertical support poles, and the center of gravity of the entire safety isolation fence is lower than half of its height, increasing stability.

[0025] When fencing is needed, select a number of fences that are appropriate for the area. If the size is not suitable and fine adjustments are needed, the telescopic fence rod 1 can be extended or retracted to achieve the appropriate size.

[0026] When the fence needs to be moved, loosen the fixing nut 42 and the locking nut 43, adjust the height of the screw 41 so that the traveling wheel 44 contacts the ground, making it easy to move. After the fence is formed, adjust the screw 41 in the opposite direction so that the traveling wheel 44 separates from the ground. At this time, the movement of the fence can be restricted, effectively preventing the fence from being moved accidentally.

[0027] When a staff member needs to enter or exit, the staff member uses a controller to open the magnetic lock 3, and then moves the fence to enter or exit. After entering or exiting, the staff member uses the controller to lock the magnetic lock 3 again. This not only prevents unauthorized personnel from entering, but also connects adjacent fences to prevent them from being blown down by the wind.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications made based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
