Description

Technical Field

[0001] This utility model relates to the field of power construction protection technology, specifically a safety protection device for power construction sites. Background Technology

[0002] In urban construction and engineering projects, many power facilities need to be built. When constructing and maintaining power facilities, construction workers usually use guardrails to isolate the construction area in order to protect the construction site and the safety of construction workers and the public.

[0003] Currently, most construction sites commonly use a type of retractable guardrail. This guardrail consists of two support posts on both sides and a retractable diamond-shaped mesh fence connected between the support posts. Its retractable nature makes it convenient to use and carry, and therefore it is widely used.

[0004] When the existing guardrails are deployed on the construction site, two people are needed to pull two support posts to quickly set up the guardrails. However, when there are no available personnel, if a single person deploys the guardrails, excessive force or force may cause one support post to be pulled away from its position, thus requiring the position of the other support post to be readjusted. Therefore, the existing guardrails have limitations in use and need to be further improved in terms of ease of use. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a safety protection device for power construction sites.

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

[0007] A safety protection device for power construction sites includes a first support column, a second support column, and a retractable diamond-shaped mesh barrier. The two support columns are provided with receiving grooves on opposite sides, and the two sides of the barrier are located in the receiving grooves of the two support columns. The ends of the movable connecting rods on both sides of the barrier are movably connected to the two support columns and can rotate and slide vertically. The first support column is provided with an adjustment mechanism, and the bottom of the second support column is provided with casters.

[0008] The adjustment mechanism includes an adjustment rod and a slider. The adjustment rod is located in the receiving groove of the first support column and extends vertically. The adjustment rod is rotatably connected to the top of the first support column. The upper end of the adjustment rod extends out of the first support column and is equipped with a crank for driving the adjustment rod to rotate around its central axis. The rod body of the adjustment rod located in the receiving groove is provided with a threaded rod segment. The slider is sleeved on the adjustment rod and can be threadedly engaged with the threaded rod segment. The end of the movable connecting rod near the first support column is hinged to the slider.

[0009] The safety protection device for power construction sites provided in this application allows the sliding block to move up and down by rotating the adjusting rod, which in turn causes the hinged end of the movable connecting rod to move up and down, thereby enabling the barrier net to expand and contract, completing the installation and storage of the safety protection device. The device provided in this application requires only one person to fix the first support column and rotate the adjusting rod on the first support column to complete the installation, reducing the limitations of the device in use and improving ease of use.

[0010] Furthermore, the adjusting rod has two threaded sections, with a preset distance between them. The upper threaded section is used when the device is in the retracted state, and the lower threaded section is used when the device is extended beyond the reach of one person's arm or when it is retracted from the extended state.

[0011] Furthermore, of the two threaded rod segments, the length of the upper threaded rod segment is less than the length of the other threaded rod segment.

[0012] Furthermore, the end of the movable link that is hinged to the slider is the upper end of the movable link.

[0013] Furthermore, the first support column has a fixing part in the receiving groove, and the lower end of the adjusting rod is rotatably connected to the fixing part, which supports the adjusting rod, reduces the influence of torque on the adjusting rod, improves the service life of the adjusting rod, and also improves the smoothness of the adjusting rod when rotating.

[0014] Furthermore, the slider includes a slip ring and a connecting lug. The slip ring is fitted onto the adjusting rod, and the connecting lug is located on the outer ring surface of the slip ring and is hinged to the movable connecting rod.

[0015] Furthermore, both support columns include a crossbeam and a vertical beam extending upward from the middle of the top of the crossbeam, with a receiving groove opened on the vertical beam, and casters located below the crossbeam of the second support column.

[0016] Furthermore, the lateral dimension of the vertical beam of the second support column is smaller than the lateral dimension of the vertical beam of the first support column.

[0017] Furthermore, the vertical thickness of the crossbeam of the second support column is less than the vertical thickness of the crossbeam of the first support column.

[0018] Furthermore, the first support column and the second support column are made of different materials, and the second support column is made of a lightweight material.

[0019] This utility model provides a safety protection device for power construction sites. By adjusting the mechanism, the first support column can be controlled, and the device can be deployed by rotating the adjusting rod. This saves manpower, reduces the limitations of the device in use, and improves ease of use. Attached Figure Description

[0026] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a safety protection device for power construction sites, which is used to set up barriers at power construction sites. When in use, multiple devices work together to isolate the power construction site.

[0027] The device includes a first support column 1, a second support column 2, and a retractable diamond-shaped mesh barrier 3. The two support columns have receiving grooves on opposite sides, and the barrier 3 is located within these receiving grooves on both sides of the two support columns.

[0028] The barrier net 3 is a diamond-shaped mesh structure formed by several connecting rods hinged together. For details, please refer to the structure of the barrier net 3 in currently available telescopic guardrails; this application will not describe it in detail here. Each side of the barrier net 3 has a movable connecting rod 31, the end of which is movably connected to two support columns and can rotate and slide vertically. The remaining connecting rods on both sides of the barrier net 3 are hinged to the two support columns. The ends of the movable connecting rods 31 that are movably connected to the support columns slide up and down as the barrier net 3 extends and retracts as a whole.

[0029] An adjustment mechanism is provided on the first support column 1, which includes an adjustment rod 11 and a slider 12. The adjustment rod 11 is located in the receiving groove of the first support column 1 and extends vertically. The adjustment rod 11 is rotatably connected to the top of the first support column 1 via a bearing. The upper end of the adjustment rod 11 extends out of the first support column 1 and is provided with a crank 13 for driving the adjustment rod 11 to rotate around its central axis. The rod body of the adjustment rod 11 located in the receiving groove is provided with a threaded rod section 111. The slider 12 is sleeved on the adjustment rod 11 and can be threadedly engaged with the threaded rod section 111. The end of the movable connecting rod 31 near the first support column 1 is hinged to the slider 12.

[0030] Rotate the adjusting rod 11 to move the slider 12 up and down. When the slider 12 moves down, the barrier 3 expands; when the slider 12 moves up, the barrier 3 contracts.

[0031] Both the first support column 1 and the second support column 2 include a crossbeam and a vertical beam extending upwards from the middle of the top of the crossbeam, with a receiving groove formed on the vertical beam. In this embodiment, the crossbeam of the first support column 1 is in direct contact with the ground, while a caster 21 is provided below the crossbeam of the second support column 2. By differentiating the two support columns, with the first support column 1 as the fixed end and the second support column 2 as the sliding end, the operator only needs to control the first support column 1 and rotate the adjusting rod 11 to control the sliding of the second support column 2 towards and away from the ground. In addition, after the device is folded, the caster 21 of the second support column 2 can also provide a moving wheel function when the device is transported, making it convenient and labor-saving to move the device.

[0032] Furthermore, in order to improve the flexibility of movement of the second support column 2, the lateral dimension of the vertical beam of the second support column 2 is smaller than that of the vertical beam of the first support column 1, so as to reduce the weight of the second support column 2.

[0033] In addition, the vertical thickness of the crossbeam of the second support column 2 can be set to be less than the vertical thickness of the crossbeam of the first support column 1, and the first support column 1 and the second support column 2 can be made of different materials, with the second support column 2 being made of lightweight material, to further reduce the weight of the second support column 2.

[0034] like Figure 3 As shown, the adjusting rod 11 in this embodiment has two threaded rod segments 111, with a preset distance between them. The threads of the two threaded rod segments 111 are externally protruding threads, and there is a smooth rod segment 112 between the two threaded rod segments 111. The slider 12 can slide on the smooth rod segment 112, engaging with the upper threaded rod segment 111 threadedly upwards and with the lower threaded rod segment 111 threadedly downwards.

[0035] The upper threaded rod section 111 is used when the device is in the retracted state, and the lower threaded rod section 111 is used when the device is extended beyond the reach of one person's arm or when it is retracted from the extended state.

[0036] When the device is in the retracted state, the slider 12 is threadedly connected to the threaded rod segment 111 located above, locking the device and keeping it in the retracted state.

[0037] When the device needs to be deployed, rotate the adjusting rod 11 to move the slider 12 down onto the smooth rod section 112, first disconnecting it from the threaded rod section 111 located above, thus releasing the lock. During this process, the second support column 2 can be pushed away from the first support column 1 by hand to reduce the resistance of the adjusting rod 11 in moving the slider 12.

[0038] Then, the operator can quickly pull the second support column 2 away from the first support column 1 by hand, with the pulling distance set within the reach of one person's arm. During this process, the slider 12 slides on the smooth rod section 112. This step can greatly shorten the deployment time of the device and improve the deployment efficiency. At the same time, deploying the device a certain distance first makes the subsequent action of driving the slider 12 to deploy the device through the screw thread less strenuous.

[0039] As the second support column 2 is pushed away from the first support column 1 by the hand, the slider 12 moves downward until it contacts the threaded rod segment 111 located below. Then, by rotating the adjusting rod 11, the threaded rod segment 111 located below is used to adjust the extension and retraction of the device beyond the arm span of one person, without the need for a second person to assist.

[0040] Specifically, of the two threaded rod segments 111, the length of the upper threaded rod segment 111 is less than the length of the other threaded rod segment 111.

[0041] Furthermore, the end of the movable link 31 that is hinged to the slider 12 is the upper end of the movable link 31, so as to shorten the length of the adjusting rod 11.

[0042] The slider 12 includes a slip ring 121 and a connecting ear 122. The slip ring 121 is fitted on the adjusting rod 11, and the connecting ear 122 is located on the outer ring surface of the slip ring 121 and is hinged to the movable connecting rod 31.

[0043] In addition, a fixing part 14 is provided in the receiving groove of the first support column 1. The lower end of the adjusting rod 11 is rotatably connected to the fixing part 14, which supports the adjusting rod 11, reduces the influence of torque on the adjusting rod 11, improves the service life of the adjusting rod 11, and also improves the smoothness of the adjusting rod 11 when rotating.

[0044] The power construction site safety protection device provided in this application can be set up by a single person fixing the first support column 1 and rotating the adjusting rod 11 on the first support column 1, which reduces the limitations of the device in use and improves the ease of use.

[0045] In addition, the threaded section 111 on the adjusting rod 11 not only has an adjusting function, but also a locking function for the position of the device. Whether in the retracted or unfolded state, the device is locked by the threaded engagement between the threaded section 111 and the slider 12, so that the device will not unfold in the retracted state, making it convenient for handling; and in the unfolded state, it will not retract due to collision or unauthorized personnel, thus improving the device's protective effect and stability.
