Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction protection technology, specifically a protective device for power grid construction. Background Technology
[0002] In power grid construction, protective devices are key equipment to ensure the safety of workers and the stable operation of equipment. Currently, telescopic fences are commonly used, also known as telescopic gates or mobile fences. They are fences whose length can be adjusted as needed.
[0003] Patent CN220747858U discloses an adjustable, reinforced telescopic fence, comprising a symmetrically arranged support structure and a telescopic fence mounted thereon. The support structure includes columns with connectors and first limiting grooves, and an adjustable, reinforced structure at the bottom of the columns. This telescopic structure offers convenient and flexible storage and transportation, occupies a small area, and is easy to deploy. The adjustable support structure, combined with reinforced fixing, better adapts to stable placement on various uneven terrains. The overall structure is simple, easy to use, easy to store, and highly practical.
[0004] However, the aforementioned retractable fences still have the following problems in actual use:
[0005] Telescopic fences are typically designed to fold for easy storage. When using them, one end of the fence post must first be fixed in a specific position. Then, the other end post is lifted and pulled to one side. This allows adjustment of the fence length by unfolding the diagonal brace between the two posts. However, after a period of use, dust accumulation or rust can cause the hinge between the diagonal braces to become stuck. In this case, when attempting to extend the second post, the initially fixed first post may be accidentally moved. Therefore, after positioning the second post, it may be necessary to return and readjust the position of the first post, and this process may need to be repeated for the same reason, which is both time-consuming and laborious.
[0006] Although existing telescopic fences are equipped with anti-slip pads at the bottom of the posts to increase stability, in actual operation, in order to smoothly extend and move the second post, it usually needs to be slightly lifted off the ground. This means that during the extension process, the anti-slip pads on the bottom of the first post cannot be fully in contact with the ground, resulting in a significant reduction in its anti-slip performance and increasing inconvenience in use. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a protective device for power grid construction, which can increase the stability between the first column and the ground when the second column is pulled.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective device for power grid construction, comprising two columns, two base plates respectively installed at the lower ends of the two columns, and several diagonal rods installed between the two columns. Pushing components are connected to the bottom surfaces at both ends of the two base plates, and a No. 1 U-shaped block is also fixedly connected to the bottom surfaces at both ends of the two base plates. The lower end of the pushing component penetrates into the interior of the No. 1 U-shaped block and is connected to a moving component. The lower end of the moving component is connected to an anti-slip component.
[0009] Furthermore, spring cavities are provided on the bottom surfaces at both ends of the base plate, and the upper end of the pushing component is located inside the spring cavity.
[0010] Furthermore, the pushing component includes a pressure block, a compression spring, and a connecting rod. The upper end of the compression spring is fixedly connected to the top surface of the spring cavity, and the lower end of the compression spring is fixedly connected to the upper end of the connecting rod. The lower end of the connecting rod penetrates into the interior of the first U-shaped block and is fixedly connected to the upper surface of the pressure block. The bottom surface of the pressure block abuts against the moving component.
[0011] Furthermore, the moving component includes a moving wheel and a second U-shaped block. The upper end of the second U-shaped block is rotatably connected to the lower end of the first U-shaped block via a first rotating shaft. The lower end of the second U-shaped block is rotatably connected to the moving wheel via a second rotating shaft, and the outer side of the lower end of the second U-shaped block is connected to the anti-slip component.
[0012] Furthermore, the anti-slip component includes a third U-shaped block and an anti-slip pad. One end of the third U-shaped block is fixedly connected to the outer wall of the lower end of the second U-shaped block, and the other end of the third U-shaped block is fixedly connected to one side of the anti-slip pad. The third U-shaped block and the second U-shaped block are set at an angle of °.
[0013] Furthermore, a baffle is fixedly connected to the lower end of the first U-shaped block away from the diagonal bar, and one side of the baffle abuts against the pressure block and the second U-shaped block.
[0014] Furthermore, lifting ports are provided through the lower end of both spring cavities near the baffle. U-shaped foot pedals are fixedly connected to the ends of the two connecting rods located outside the first U-shaped block. The middle part of the U-shaped foot pedal is located on the outside of the base plate, and the outer walls of both ends of the U-shaped foot pedal are slidably connected to the inner walls of the two lifting ports respectively.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This type of protective device for power grid construction uses push components installed at both ends of the base plate below the column. The push components are connected to a U-shaped block, a moving component, and an anti-slip component. When two columns need to be deployed, the anti-slip component keeps the column in close contact with the ground to increase friction, thereby reducing the probability of the first column shifting when the second column is pulled.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figures 1-4 A protective device for power grid construction includes two columns 1, two base plates 3 respectively installed at the lower ends of the two columns 1, and several diagonal rods 2 installed between the two columns 1. The bottom surfaces at both ends of the two base plates 3 are connected to a pushing component, and the bottom surfaces at both ends of the two base plates 3 are also fixedly connected to a No. 1 U-shaped block 5. The lower end of the pushing component penetrates into the interior of the No. 1 U-shaped block 5 and is connected to a moving component. The lower end of the moving component is connected to an anti-slip component.
[0024] The protective device for power grid construction described in this utility model is structurally similar to existing protective devices for power grid construction, such as the adjustable, robust, telescopic fence disclosed in patent publication number CN220747858U. Figures 1 to 4 As shown, when using the protective device for power grid construction in this utility model, firstly, the two pushing components inside the No. 1 column 1 are lifted upwards, so that the two pushing components can remove the restriction on the moving component. At this time, the two moving components can be folded to one side. After the moving component is folded, the anti-slip component on one side of the moving component can be pressed tightly against the ground, thereby increasing the friction between the No. 1 column 1 and the ground.
[0025] At this time, because there is a moving component under the second column 1 (i.e., the base plate 3), and because the moving component on the first column 1 has been folded, there is a height difference between the two columns 1. Also, because there is friction from the anti-slip component at the bottom of the first column 1, the construction workers only need to pull the second column 1 to one side through the moving component under the second column 1 to pull apart several diagonal bars 2, thereby changing the distance between the two columns 1. During the pulling, the anti-slip component under the first column 1 will prevent the first column 1 from shifting.
[0026] After post 1 is unfolded to the appropriate position, simply fold the movable component below post 1 in the same way as described above, so that the anti-slip component is in contact with the ground. This will make the two posts 1 horizontal and also improve the overall stability of the fence during construction by using the four anti-slip components.
[0027] After construction is completed, simply lift column 1 and base plate 3 upwards. At this point, the anti-slip components will detach from the ground, and the moving components can be folded back in the original direction for easy relocation.
[0028] In a preferred embodiment of this utility model, spring cavities 302 are provided on the bottom surfaces of both ends of the base plate 3, and the upper end of the pushing component is located inside the spring cavity 302. The pushing component includes a pressure block 8, a compression spring 12, and a connecting rod 13. The upper end of the compression spring 12 is fixedly connected to the top surface of the spring cavity 302, and the lower end of the compression spring 12 is fixedly connected to the upper end of the connecting rod 13. The lower end of the connecting rod 13 penetrates into the interior of the first U-shaped block 5 and is fixedly connected to the upper surface of the pressure block 8. The bottom surface of the pressure block 8 abuts against the moving component.
[0029] More specifically, when it is necessary to fold the moving component to one side of the bottom plate 3, simply push the pressure block 8 upward. The pressure block 8, under force, pushes the connecting rod 13 upward, and then the connecting rod 13 rises to compress the compression spring 12, thereby changing the height of the pressure block 8. When it is necessary to rotate the moving component back to the bottom plate 3, simply lift the column 1 upward. At this time, the moving component can automatically reset due to gravity and the action of the compression spring 12, which is convenient and easy to operate.
[0030] As a preferred embodiment of this utility model, the moving component includes a moving wheel 6 and a second U-shaped block 9. The upper end of the second U-shaped block 9 is rotatably connected to the lower end of the first U-shaped block 5 through a first rotating shaft. The lower end of the second U-shaped block 9 is rotatably connected to the moving wheel 6 through a second rotating shaft. The outer side of the lower end of the second U-shaped block 9 is connected to the anti-slip component.
[0031] More specifically, when not stored, the entire fence can be moved using the four casters 6 under the two base plates 3. When the fence needs to be confined to one position, as the pressure block 8 moves upward, the second U-shaped block 9 is no longer restricted by the pressure block 8 and can be rotated to one side via the first pivot axis, thus folding together with the casters 6.
[0032] As a preferred embodiment of this utility model, the anti-slip component includes a third U-shaped block 10 and an anti-slip pad 11. One end of the third U-shaped block 10 is fixedly connected to the outer wall of the lower end of the second U-shaped block 9, and the other end of the third U-shaped block 10 is fixedly connected to one side of the anti-slip pad 11. The third U-shaped block 10 and the second U-shaped block 9 are set at 90°.
[0033] More specifically, because the third U-shaped block 10 and the second U-shaped block 9 are set at 90°, they will not obstruct the movement of the moving wheel 6 when it moves normally. Similarly, when the moving wheel 6 is folded to one side, it will not affect the friction between the anti-slip mat 11 and the ground.
[0034] It should be noted that because there is a height difference between the two columns 1, and because the second U-shaped block 9 and the first U-shaped block 5 are rotatably connected, the anti-slip pad 11 connected to the second U-shaped block 9 can adapt to this height difference and keep the anti-slip pad 11 always in contact with the ground.
[0035] As a preferred embodiment of this utility model, a baffle 7 is fixedly connected to the side of the lower end of the first U-shaped block 5 away from the inclined rod 2, and one side of the baffle 7 abuts against the pressure block 8 and the second U-shaped block 9.
[0036] More specifically, by setting the baffle 7, the folding direction of the second U-shaped block 9 can be restricted, so that the second U-shaped block 9 can only be folded towards the diagonal bar 2, thereby reducing the external space, while ensuring that one side of the anti-slip mat 11 is in contact with the ground.
[0037] As a preferred embodiment of this utility model, a lifting port 301 is provided through the lower end of the two spring cavities 302 near the baffle 7. The two connecting rods 13 are fixedly connected to the U-shaped foot pedal 4 at one end outside the first U-shaped block 5. The middle part of the U-shaped foot pedal 4 is located outside the base plate 3, and the outer walls of both ends of the U-shaped foot pedal 4 are slidably connected to the inner walls of the two lifting ports 301 respectively.
[0038] More specifically, by setting up a U-shaped foot pedal 4, it is easier to operate when lifting the high pressure block 8, and the two pressure blocks 8 on the same base plate 3 can be raised simultaneously by a single foot pedal action, making it convenient and easy to operate.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
