Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a protective device for protecting high-voltage lines outside construction sites. Background Technology

[0002] When tower cranes are used on site, there are overhead high-voltage cables around the construction site. At this time, the high-voltage lines may be within the lifting range of the tower crane. There may be a risk of electric shock and damage to the high-voltage cables when lifting materials. Existing technology often uses whole steel lattice columns as high-voltage line protection, which are generally about 10m long. They occupy a lot of space for stacking and transportation. During installation, a truck crane is usually required to assist in the installation, and manual adjustment of verticality is done using guy ropes, which is quite cumbersome. Utility Model Content

The foldable diagonal bracing includes an upper clamp, a lower clamp, and several sets of foldable diagonal bracing connected between the upper clamp and the lower clamp. The foldable diagonal bracing includes an upper diagonal rod fixedly connected to the upper clamp and a lower diagonal rod hinged to the lower clamp. The outwardly extending ends of the upper diagonal rod and the lower diagonal rod are hinged to the same horizontal rod.

[0005] More preferably, the steel lattice column includes a base section fixed to the ground concrete foundation, several standard sections for height extension, and a top section, with the lower part of the base section bolted to the ground concrete foundation.

[0006] Furthermore, four sets of foldable diagonal braces are centrally symmetrically arranged on the four sides of the clamp. Each set of foldable diagonal braces includes two upper diagonal rods and two lower diagonal rods arranged in parallel. The two upper diagonal rods and the two lower diagonal rods are simultaneously hinged to a horizontal rod.

[0007] Furthermore, the upper and lower diagonal rods are rotatably connected to the horizontal rod via sleeves.

[0008] Furthermore, round steel ladders are installed at intervals from bottom to top on the steel lattice columns.

[0009] Furthermore, a detachable operating platform is provided on the standard section of the upper part of the steel lattice column near the U-shaped protective rope limiting component.

[0010] Furthermore, the detachable operating platform includes platform clamps, platform base plate, and railings. The platform clamps and upper clamps are both fixed to the steel lattice column by through bolts. The through bolts pass through the steel lattice column and are fixed to both sides of the clamps.

They can be stacked during storage and transportation, saving space. During installation, construction workers use a ladder truck to connect the various lattice column components, which is efficient and convenient.

[0014] After the foldable diagonal brace is assembled off-site, it can be installed on the steel lattice column in sequence using upper and lower clamps to form diagonal support for the steel lattice column, thereby compensating for the deficiency of weak connection strength between the nodes of the steel lattice column.

The top surface of the U-shaped protective rope limiting component 2 is provided with a night warning light 3. The U-shaped protective rope limiting component 2 is welded to the top surface of the steel lattice column 1 with the opening facing downward. The protective steel wire rope 4 passes through the opening of the U-shaped protective rope limiting component 2 to form a high-voltage line protection warning line. The steel lattice column 1 is also provided with a foldable diagonal brace 5 between itself and the ground. The foldable diagonal brace 5 includes an upper clamp 51, a lower clamp 52, and several sets of foldable diagonal braces 53 connected between the upper clamp 51 and the lower clamp 52. The foldable diagonal brace 53 includes an upper diagonal rod 531 fixedly connected to the upper clamp 51 and a lower diagonal rod 532 hingedly connected to the lower clamp 52. The outwardly extending ends of the upper diagonal rod 531 and the lower diagonal rod 532 are hingedly connected to the same horizontal rod 533.

[0020] Example 2 Based on Embodiment 1, the steel lattice column 1 includes a base section 11 fixed to the ground concrete foundation 9, several standard sections 12 for height extension and a top section 13, with the lower part of the base section 11 bolted to the ground concrete foundation 9.

[0021] The base section 11, standard section 12 and top section 13 are all rectangular frame structures made of φ60mm×3mm steel pipe columns, 50mm angle steel lateral supports and 30mm angle steel diagonal tie rods.

[0022] Four sets of foldable diagonal braces 53 are centrally symmetrically arranged on the four sides of the clamp. Each set of foldable diagonal braces 53 includes two parallel upper diagonal rods 531 and two lower diagonal rods 532. The two upper diagonal rods 531 and the two lower diagonal rods 532 are simultaneously hinged to a horizontal rod 533. The two upper diagonal rods 531 can be fixed to the upper clamp through a cross-shaped pipe clamp. The upper clamp 51 can be made by bolting four channel steels together to form a rectangular frame. The frame structure is connected to the steel lattice column body by through-bolts. The lower clamp 52 can be made of four round steel bars connected by pipe clamps, and then the round steel bars are connected to the steel lattice column by cross clamps. The upper diagonal bar 531 and the lower diagonal bar 532 can be rotatably connected to the horizontal bar 533 through sleeves. Round steel ladders 6 are provided on the steel lattice column 1 from bottom to top. A detachable operating platform 7 is provided on the standard section 12 of the upper part of the steel lattice column 1 near the U-shaped protective rope limiter 2.

[0023] Example 3 Based on Embodiment 2, the detachable operating platform 7 includes a platform clamp 71, a platform base plate 72, and a railing 73. The platform clamp 71 and the upper clamp 51 are both fixed to the steel lattice column 1 by through bolts 8. The through bolts 8 pass through the steel lattice column 1 and are fixed to both sides of the clamp. The lower clamp 52 is fixed to the steel lattice column 1 by a scaffold cross clamp. During installation, the upper clamp 51 is first fixed to the steel lattice column 1 according to the length of the upper diagonal bar 531. Then the lower clamp 52 moves upward until the lower diagonal bar 532 can no longer move, and the horizontal bar 533 is supported on the ground, forming a circumferential diagonal stable support for the steel lattice column 1.

[0024] The upper part of the base section 11 is provided with a connector 1A, the upper and lower parts of the standard section 12 are provided with connector 1A and plug 1B respectively, and the lower part of the top section 13 is provided with plug 1B; the adjacent base section 11 and standard section 12, standard section 12 and standard section 12, and standard section 12 and top section 13 are all connected and fixed by plug 1B inserted into connector 1A. Connector 1A is a φ54mm plug.

[0025] Conventional high-voltage line protection devices are quite long, and it is difficult to adjust the verticality of a single hoisting method. Therefore, it is considered to disassemble them and then assemble them by interlocking to ensure the flatness of the high-voltage line protection foundation is in place, thereby reducing the verticality error after the high-voltage line protection device is assembled.

[0026] Construction process: Step 1: Transport the assembled high-voltage line protection device to the assembly site; Step 2: Connect and fix the base section of the protective device to the pre-embedded bolts in the concrete foundation; Step 3: Personnel can install the standard sections of the protective device sequentially by climbing the ladder and using the operating platform; Step 4: Tighten the bolts at the interlocking positions of the protective device column; Step 5: Install foldable diagonal braces and ground supports to ensure protective stability; Step 6: Install protective steel wire ropes and night warning lights on the top section of the protective device.
