Description

Technical Field

[0001] The utility model relates to the technical field of building construction safety protection, in particular to a high-voltage line offline construction protection device. Background Art

[0002] When construction is carried out under overhead high-voltage lines, in order to prevent ground construction equipment, such as cranes, from touching the overhead high-voltage lines and causing safety hazards, a protective structure is usually set up between the construction equipment and the overhead high-voltage lines to ensure safety. During the high-voltage line construction process, the construction party often measures the safety distance in advance according to the voltage of the high-voltage line transmission circuit, and installs protective equipment at the minimum safety distance, such as setting up poles and pulling up warning lines. The poles are usually made of wooden racks, and the isolation measures are generally made of steel wire ropes, and colorful flags are hung as a warning.

[0003] When installing poles and wooden racks, construction parties often use large machinery for installation and lifting. During the installation and lifting process, there is a risk that the machinery and lifting equipment used will touch the high-voltage wires, causing harm to the construction workers. At the same time, in the subsequent construction process, there is also a risk of touching the high-voltage wires when using large machinery, causing harm to the construction workers. Due to the construction period, the wooden racks have the probability of decay and collapse after long-term use, and cannot provide effective protection, causing harm to the construction workers. Summary of the invention

[0004] In order to reduce the damage to construction workers when constructing under high-voltage power lines, the present application provides a protective device for construction under high-voltage power lines.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the above-mentioned construction protection equipment under high-voltage lines comprises a plurality of mounting seats, wherein the plurality of mounting seats are evenly installed on the ground according to the construction area, and a telescopic rod is installed at one end of the mounting seats away from the ground, and a pulley block is arranged at one end of the telescopic rod away from the mounting seat, a traction rope is inserted in the pulley block, and the end of the traction rope away from the pulley block is connected to the mounting seat, the pulley block is connected to a connecting rope, and the end of the connecting rope away from the pulley block is connected to a protective net.

[0006] The beneficial effects are: by evenly arranging the mounting seats at the edge of the construction area, the protective net is raised to a certain height to cover the construction area through the telescopic rods and pulleys arranged on the mounting seats, so that the construction area is covered by the protective net, and when the construction workers are working in the construction area, the protective net prevents the various mechanical equipment used in the construction from directly contacting the high-voltage wires, thereby avoiding injuries to the construction workers caused by contact with the high-voltage wires during the construction process; at the same time, the arrangement of the mounting seats and the lifting rods eliminates the need to erect columns, reducing injuries caused by accidental contact with the high-voltage wires during the erection of columns; and the arrangement of the mounting seats and the telescopic rods also avoids the decay of wooden racks during the construction period, so that the protective net can cover the construction area through the telescopic rods during the construction period to ensure safety during the construction process.

[0007] A further technical solution of the utility model is that a plurality of net-supporting ropes are arranged on the side of the protective net facing the ground.

[0008] The beneficial effect is that the support rope is set to provide support for the protective net, reduce the degree of sagging of the protective net toward the ground, and reduce the impact of the sagging of the protective net on the construction space.

[0009] A further technical solution of the utility model is that the pulley block includes a fixed pulley and a movable pulley, the fixed pulley is fixedly connected to the telescopic rod, the movable pulley is connected to the fixed pulley through a traction rope, a winding barrel is installed on the mounting seat, and the traction rope is wound around the winding barrel at one end away from the pulley block.

[0010] The beneficial effect is that the force required by construction workers when using the winding barrel to reel in the traction rope is reduced through the arrangement of the fixed pulley and the movable pulley.

[0011] A further technical solution of the utility model is that a power piece is arranged on the mounting seat, an output end of the power piece is connected to the winding barrel, and the power piece drives the winding barrel to rotate.

[0012] The beneficial effect is that the winding barrel is driven to rotate by the power part to store and release the traction rope, thereby reducing the workload of construction workers when raising the protective net.

[0013] A further technical solution of the utility model is that an oblique brace is provided between the telescopic rod and the mounting seat.

[0014] The beneficial effect is that due to the space in the construction area, the length of the telescopic rod is often relatively high, and the stability of the telescopic rod when in use is improved by installing the diagonal brace.

[0015] A further technical solution of the utility model is that a plurality of rollers are arranged at the bottom of the mounting seat.

[0016] The beneficial effect is that the installation seat can slide by setting the roller, so that the construction workers can adjust the position of the installation seat according to the size of the construction area.

[0017] A further technical solution of the utility model is that a plurality of support columns are threadedly mounted on the bottom of the mounting seat.

[0018] The beneficial effect is that when the roller slides the mounting seat to the corresponding position, the support rod provides support for the mounting seat so that it is in a stable environment, thereby reducing the impact of roller sliding during use on the stability of the protective equipment.

[0019] A further technical solution of the utility model is that a rubber pad is arranged at one end of the support column facing the ground.

[0020] The beneficial effect is that the rubber pad increases the contact area between the support column and the ground while providing a buffer for the mounting seat, further improving the stability of the protective equipment during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-2As shown, a high-voltage line under-construction protection device, in this embodiment, includes four mounting seats 1, the four mounting seats 1 are respectively installed at four corners of the high-voltage line under-construction area, and the four mounting seats 1 are all installed on the ground; a telescopic rod 2 is fixedly installed at one end of the mounting seat 1 away from the ground, the telescopic rod 2 is vertically installed on the mounting seat 1, and a pulley block 3 is installed on the top of the telescopic rod 2, the pulley block 3 includes a fixed pulley 31 and a movable pulley 32, the fixed pulley 31 is fixed on the telescopic rod 2, a traction rope 4 is passed between the fixed pulley 31 and the movable pulley 32, the traction rope 4 connects the movable pulley 32 with the fixed pulley 31, the traction rope 4 is connected to the mounting seat 1 at one end away from the pulley block 3, and the traction rope 4 is fixedly connected to the telescopic rod 2 at one end toward the pulley block 3 A connecting shell is installed outside the movable pulley 32, and connecting rings 15 are fixedly installed at both ends of the connecting shell in the height direction. A connecting rope 5 is fixedly installed on the connecting ring 15, and the end of the connecting rope 5 away from the connecting ring 15 is connected to the protective net 6; when the telescopic rod 2 moves away from the mounting seat 1, the pulley block 3 moves away from the ground along with the telescopic rod 2 and then away from the ground, and the protective net 6 slides away from the ground under the action of the connecting rope 5. When the protective net 6 rises to a set safe height, the telescopic rod 2 stops moving to fix the height of the pulley block 3 and the protective net 6. At this time, the protective net 6 covers the construction area, reducing the probability of contact between construction equipment and high-voltage lines during construction, and reducing the damage to construction personnel caused by indirect or direct contact with high-voltage lines.

[0026] Reference Figure 1 A plurality of net-supporting ropes 7 are installed at one end of the protective net 6 facing the ground, and the net-supporting ropes 7 are used to reduce the influence of the sagging of the protective net 6 due to its own gravity during use on the construction space.

[0027] Reference Figure 2 A power part 9 is installed on the mounting base 1. The power part 9 is a motor. The output end of the motor is connected to a winding barrel 8. The winding barrel 8 is installed on the mounting base 1. The end of the traction rope 4 away from the fixed pulley 32 is wound on the winding barrel 8. The motor drives the winding barrel 8 to rotate. When the protective equipment is used up, it needs to be recycled. The winding barrel 8 reels the traction rope 4 to reduce the impact of the lack of rewinding of the traction rope 4 on the next use. At the same time, it also makes the traction rope 4 and the fixed pulley 32 in a taut state, reducing the shaking of the pulley block 3 during the transportation of the mounting base 1, reducing the damage to the pulley block 3, and facilitating the next use.

[0028] The protective net 6, traction rope 4, support net rope 7 and connecting rope 5 are all made of Dyneema rope. Dyneema rope has high strength: the strength is more than 10 times that of high-quality steel; high modulus: second only to special carbon fiber; low density: smaller than water, can float on the water surface; has high crystallinity, and chemical groups that are not easy to react with chemical agents. Therefore, it is resistant to water, moisture, chemical corrosion, and UV, so it does not need to be treated with UV resistance. It is corrosion-resistant, acid-resistant, and has excellent wear resistance. It not only has high modulus, but also is soft and has a long flex life. The melting point of high-strength and high-modulus polyethylene fiber is between 144 and 152°C. Short-term exposure to an environment of 110°C will not cause serious performance degradation.

[0029] Reference Figure 1 A mounting plate 14 is fixedly installed circumferentially at one end of the mounting seat 1 facing the ground, and the mounting plate 14 is installed horizontally. A plurality of rollers 11 are installed on the mounting plate 14, and the rollers 11 make the mounting seat 1 easy to move, reducing the probability of problems in the handling process caused by the large size of the mounting seat 1; a plurality of support columns 12 are evenly installed on the mounting plate 14, and the support columns 12 are threadedly connected to the mounting plate 14. When the mounting seat 1 is moved to the installation position by the rollers 11, the support columns 12 are rotated to rotate toward the ground, and a rubber pad 13 is installed at one end of the support column 12 facing the ground. The rubber pad 13 moves toward or away from the ground as the support column 12 rotates. When the rubber pad 13 abuts against the ground, the support column 12 makes the mounting seat 1 in a stable state, reducing the shaking of the mounting seat 1 during use. The rubber pad 13 increases the contact area between the support column 12 and the ground while making the contact between the support column 12 and the ground more stable, that is, further improving the stability of the mounting seat 1.

[0030] Reference Figure 1 In this embodiment, the telescopic rod 2 uses an electric push rod, which makes the telescopic rod 2 extend and retract into an automated process, thereby reducing the workload of construction personnel. In order to improve the stability of the telescopic rod 2 during lifting and use, a diagonal brace 10 is installed between the mounting seat 1 and the telescopic rod 2. One end of the diagonal brace 10 in the length direction is rotatably mounted on the mounting seat 1, and the end of the diagonal brace 10 in the length direction away from the mounting seat 1 is connected to the outer surface of the telescopic rod 2. The diagonal brace 10 improves the stability of the telescopic rod 2 installed on the mounting seat 1.

[0031] In the utility model, when it is necessary to carry out construction under the high-voltage line, a protective net 6 of appropriate size is customized according to the construction area required by the construction, and a plurality of net-supporting ropes 7 are installed on one side of the protective net 6. After the installation of the net-supporting ropes 7 is completed, connecting ropes 5 are installed at the four corners of the protective net 6, and the end of the connecting rope 5 away from the protective net 6 is connected to the connecting ring 15 at the bottom of the movable pulley 31. After the connection is completed, the mounting seat 1 is pushed to slide to the four corners of the construction area, and the protective net 6 matching the size of the construction area is unfolded as the mounting seat 1 slides; then the support column 12 is rotated toward the ground so that the rubber pad 13 contacts the ground to make the mounting seat 1 stable. In a fixed state, the electric push rod is started, so that the electric push rod drives the pulley block 3 to move away from the ground and brings the protective net 6 off the ground. After the electric push rod stops extending and retracting, the protective net 6 reaches the corresponding height to cover the construction area; after the construction is completed, the electric push rod is extended and retracted to drive the pulley block 3 and the protective net 6 to move toward the ground, and the winding barrel 8 reels the traction rope 4 under the action of the power piece 9; after the protective net 6 descends to the ground, the construction personnel untie the connecting rope 5 from the connecting ring 15, store the protective net 6, rotate the support column 12 away from the ground, and move the mounting base 1 to the storage position through the roller 11, waiting for the next use.
