Description

Technical Field

[0001] The invention relates to the technical field of electric iron accessories, and in particular to an electric iron accessory based on an improved fixing component. Background Art

[0002] In the power system, power iron accessories are an important part of the construction and maintenance of transmission and distribution lines. They are mainly used to support and fix conductors, insulators and other related equipment to ensure the stable operation of the power system. However, in the actual installation process, the existing power iron accessory design has many shortcomings, especially in the installation of crossarms. These problems will directly affect the construction efficiency and safety.

[0003] At present, the common installation method of power iron accessories usually adopts a step-by-step operation process: first, the two cross arms are placed horizontally, and the screws and bolts are pre-tightened to achieve temporary fixation. The purpose of this preliminary fixation is to facilitate the subsequent lifting operation. Then the workers need to climb to the top of the pole, and then hoist the assembled cross arms to the specified height as a whole, and insert them from the top of the pole. Because there is a certain amount of space between the two cross arms, it is easy for the cross arms to tilt or shift during the lifting and lowering process. Once this happens, the spacing between the two cross arms may not be enough to accommodate the diameter of the pole, resulting in failure to insert smoothly. At this time, the workers must manually adjust the position of the cross arms at high altitude, and even need to force the cross arms apart to expand the spacing before continuing to complete the installation work. The above process will not only increase the labor intensity of the workers, but also reduce the installation efficiency. In addition, high-altitude operations themselves are highly risky, and any additional manual adjustments will further increase the probability of accidents and threaten the lives of workers. Summary of the invention

[0004] In view of this, the present invention provides an electric iron accessory based on an improved fixing assembly, which can overcome the shortcomings of existing electric iron accessories that reserve movable space before installation, which makes the cross arm prone to tilt or position shift during the lifting and lowering process, resulting in the cross arm being unable to be smoothly inserted into the pole. Workers have to manually force the cross arm apart at high altitude to expand the spacing, which is cumbersome to operate and has low installation efficiency.

[0005] A kind of electric power iron accessory based on an improved fixing component, comprising: cross arms, two of which are provided and the two cross arms are symmetrically arranged front and back; positioning blocks, symmetrically connected to the sides of the cross arms; screws, symmetrically and slidably connected to the cross arms; bolts, threadedly connected to the ends of the screws; connecting springs, with both ends respectively connected to the two cross arms; first rotating plates, symmetrically and rotatably connected to the top of one of the cross arms; second rotating plates, symmetrically and rotatably connected to the top of the other cross arm; bumps, connected to the ends of the second rotating plates; ejector rods, connected to the tops of the first rotating plates, and the ejector rods are in contact and cooperation with the bumps for unidirectional limiting of the first rotating plates and the second rotating plates; guiding components, arranged on the positioning blocks for guiding the cross arms to move along the electric pole.

[0006] Optionally, the guiding component comprises: a sliding tube, slidably connected to the positioning block; a ball, rotatably connected to one end of the sliding tube, and the ball is used to contact the surface of the electric pole; a connecting plate, connected to the other end of the sliding tube; a tension spring, wound outside the sliding tube, and both ends of the tension spring are respectively connected to the positioning block and the connecting plate.

[0007] Optionally, it further comprises: a spring piece, connected to the side of the positioning block; a slider, slidably connected to the positioning block, the slider is located on one side of the sliding tube, and the slider is in contact and cooperation with the spring piece; a rubber pad, connected to the side of the slider, and the rubber pad is used to contact the surface of the electric pole.

[0008] Optionally, it further comprises: an elastic rope, connected to the spring piece, and the slider is fixedly connected to the elastic rope.

[0009] Optionally, it further comprises: a connecting rod, rotatably connected to the second rotating plate; a push rod, rotatably connected to the end of the connecting rod far from the second rotating plate.

[0010] Optionally, it further comprises: mounting rings, spaced and connected to the sides of the front cross arm, and the screws pass through the inner sides of the mounting rings; elastic hooks, circumferentially spaced and connected to the sides of the mounting rings, and the elastic hooks are used to hook the thread grooves on the screws.

[0011] Optionally, it further comprises: a U-shaped frame, slidably arranged at the end of the screw; rubber sheets, symmetrically connected to the sides of the U-shaped frame, and the rubber sheets are clamped between the screw and the rear cross arm.

[0012] Optionally, it further comprises: handles, symmetrically connected to the side of the U-shaped frame far from the rubber sheets.

[0013] The beneficial effects of the present invention are as follows: 1. Through the cooperation of the bump and the ejector rod, the present invention can limit and fix two cross arms, ensuring that the cross arms will not tilt or shift in position during hoisting and downward movement. When the cross arms are adjusted to the appropriate height, the worker releases the one-way limit on the first rotating plate and the second rotating plate, and the two cross arms can be automatically moved closer to the electric pole and closely attached, so that the positioning block presses against the surface of the electric pole, thus quickly completing the installation work of the cross arms and improving the installation efficiency.

[0014] 2. Through the linkage cooperation of the push rod, the connecting rod and the second rotating plate, the worker only needs to push the push rod to synchronously control the two second rotating plates to rotate away from the electric pole, so as to quickly release the limit on the cross arms. This design can significantly reduce the manual operation steps in high-altitude operations, reduce the labor intensity of workers, and improve the installation efficiency and safety at the same time.

[0015] 3. Through the cooperation of the elastic hook and the screw, when the bolt becomes loose due to long-term use, the elastic hook can effectively prevent the screw from moving backward, thus avoiding the risk of the cross arm loosening. In addition, the combined design of the rubber sheet and the U-shaped frame can prevent the screw from rotating with the bolt during the process of tightening the bolt, simplify the operation process, and further improve the reliability of the cross arm fixation and the construction efficiency.

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Embodiment: A kind of electric power iron accessory based on an improved fixing component, as Figures 1-5As shown in the figure, it includes a cross arm 1, positioning blocks 2, screw rods 3, bolts 4, connecting springs 5, first rotating plates 6, second rotating plates 7, convex blocks 8, ejector rods 9 and a guiding assembly. The number of cross arms 1 is two, and the two cross arms 1 are symmetrically arranged front and back. On the side where the two cross arms 1 are close to each other, positioning blocks 2 are symmetrically connected left and right. The number of positioning blocks 2 is four, and the shape of the positioning blocks 2 is "V" shaped. Four screw rods 3 are slidably connected between the two cross arms 1. Bolts 4 are threadedly connected to the front ends of the four screw rods 3. Connecting springs 5 are symmetrically connected left and right between the middle parts of the two cross arms 1. The number of connecting springs 5 is two. First rotating plates 6 are rotatably connected left and right at the top of the rear cross arm 1. Second rotating plates 7 are rotatably connected left and right at the top of the front cross arm 1. The second rotating plates 7 correspond to the first rotating plates 6 one by one. Convex blocks 8 are connected to the rear ends of the two second rotating plates 7. Ejector rods 9 are connected to the front sides of the tops of the two first rotating plates 6. The ejector rods 9 correspond to the convex blocks 8 one by one, and the ejector rods 9 are in contact with their corresponding convex blocks 8, which is used for one-way limiting of the first rotating plates 6 and the second rotating plates 7, so that the first rotating plates 6 and the second rotating plates 7 cannot rotate towards the direction close to the electric pole 001, but the first rotating plates 6 and the second rotating plates 7 can rotate away from the electric pole 001. The guiding assembly is used to guide the cross arm 1 to move along the electric pole 001.

[0033] As Figure 5 shown, the guiding assembly includes a sliding tube 10, a ball 11, a connecting plate 12 and a tension spring 13. A sliding tube 10 is slidably connected to each positioning block 2. A ball 11 is rotatably connected to one end of each sliding tube 10 close to the electric pole 001. A connecting plate 12 is connected to one end of each sliding tube 10 away from the electric pole 001. A tension spring 13 is wound around the outside of each sliding tube 10, and the two ends of the tension spring 13 are respectively connected to the positioning block 2 and the connecting plate 12.

[0034] In the initial state (as Figure 2As shown in the figure, the bolt 4 is in a pre-tightened state, the connecting spring 5 is in a stretched state, both the first rotating plate 6 and the second rotating plate 7 are inclined towards the direction close to the power pole 001. At this time, the two cross arms 1 will be subjected to the force of the connecting spring 5 pulling inward, so that both the first rotating plate 6 and the second rotating plate 7 will be subjected to the force of rotating to the left. Since the convex block 8 and the ejector rod 9 are in contact with each other, it can prevent the first rotating plate 6 and the second rotating plate 7 from rotating to the left, thereby preventing the two cross arms 1 from moving inward. In this way, the two cross arms 1 can be limited, ensuring that the reserved space between the two cross arms 1 can allow the power pole 001 to pass through. Then, the worker climbs to the top of the power pole 001, hoists the cross arm 1 to an appropriate height, and then the worker can put the cross arms 1 on both the front and back sides onto the power pole 001 from the top downwards, ensuring that the power pole 001 is located between the four positioning blocks 2. At this time, the ball 11 will contact the surface of the power pole 001. When the worker moves the cross arm 1 up and down to adjust the height, it can drive the ball 11 to roll up and down on the surface of the power pole 001, thereby preventing the positioning block 2 from directly contacting the surface of the power pole 001, playing a role in reducing the friction and facilitating the worker to adjust the height of the cross arm 1. After the height of the cross arm 1 is adjusted, the worker only needs to rotate the second rotating plates 7 on both the left and right sides away from the power pole 001. The second rotating plate 7 can drive the first rotating plate 6 to rotate away from the power pole 001. At this time, the convex block 8 and the ejector rod 9 will be separated, thereby releasing the limit on the cross arm 1. At this time, the connecting spring 5 will return to its original state, driving the cross arms 1 on both the front and back sides to move towards the direction close to the power pole 001. The cross arm 1 can drive the positioning block 2 to move towards the direction close to the power pole 001. Since the ball 11 is in contact with the surface of the power pole 001, the sliding tube 10, the ball 11 and the connecting plate 12 do not move with the positioning block 2, and the tension spring 13 is stretched until each positioning block 2 can contact the surface of the power pole 001. Then, the bolt 4 is tightened, and the cross arm 1 can be fixedly installed on the power pole 001.

[0035] As Figure 5 and Figure 6 shown, it further includes a leaf spring 14, an elastic cord 15, a slider 16 and a rubber pad 17. Two leaf springs 14 are connected to each positioning block 2. An elastic cord 15 is connected between the middles of the two leaf springs 14 on the same positioning block 2. A slider 16 is slidably connected to each positioning block 2, and the slider 16 is fixedly connected to the middle of the elastic cord 15. The elastic cord 15 is used to limit the slider 16 to prevent the slider 16 from detaching from the positioning block 2. A rubber pad 17 is connected to one side of each slider 16 close to the power pole 001.

[0036] In the initial state, the elastic piece 14 is in a vertical state; when the connecting spring 5 drives the positioning block 2 to move towards the direction close to the electric pole 001, the positioning block 2 will drive the slider 16 and the rubber pad 17 to move towards the direction close to the electric pole 001. The rubber pad 17 will first contact the surface of the electric pole 001. Under the limiting action of the elastic piece 14 and the elastic force of the connecting spring 5, the slider 16 can tightly press the rubber pad 17 against the surface of the electric pole 001. By means of the friction force between the rubber pad 17 and the electric pole 001, the position of the cross arm 1 can be initially fixed to prevent the cross arm 1 from sagging due to gravity, which is convenient for the worker to tighten the bolt 4 subsequently. During the tightening process of the bolt 4, the positioning block 2 will continue to move towards the direction close to the electric pole 001. At this time, the rubber pad 17 will be retracted into the positioning block 2 under the extrusion of the electric pole 001, and the rubber pad 17 will squeeze the elastic piece 14 through the slider 16 to deform and arch up, so as to ensure the close contact between each positioning block 2 and the electric pole 001 and ensure the installation stability of the cross arm 1.

[0037] As Figure 7 shown, it further includes a connecting rod 18 and a push rod 19. The middle parts of the tops of the two second rotating plates 7 are both rotatably connected with the connecting rod 18, and the front ends of the two connecting rods 18 are rotatably connected with the push rod 19. After the height of the cross arm 1 is adjusted, the worker only needs to push the push rod 19 backward, and the push rod 19 can drive the two second rotating plates 7 to rotate synchronously towards the direction away from the electric pole 001 through the connecting rod 18, thereby reducing the operation steps and improving the work efficiency.

[0038] As Figure 8 and Figure 9 shown, it further includes a mounting ring 20 and an elastic hook 21. Four mounting rings 20 are spaced and connected to the rear side of the front cross arm 1. The mounting rings 20 correspond to the screw rods 3 one by one, and the screw rods 3 all pass through the inner sides of the corresponding mounting rings 20. A plurality of elastic hooks 21 are circumferentially spaced and connected to the rear side of each mounting ring 20. The rear end of the elastic hook 21 is a slope, and the elastic hook 21 is used to hook the thread groove on the screw rod 3. When the screw rod 3 passes through the two cross arms 1 from back to front in sequence, the screw rod 3 will first contact the rear end of the elastic hook 21, thereby being able to squeeze the rear end of the elastic hook 21 to deform. When the rear end of the elastic hook 21 is aligned with the thread groove on the screw rod 3, the rear end of the elastic hook 21 will return to its original state due to its own elasticity and hook the thread groove on the screw rod 3. When the bolt 4 becomes loose due to long-term use, the elastic hook 21 can prevent the screw rod 3 from moving backward, thereby ensuring that the cross arm 1 is still stably fixed on the electric pole 001 and improving the safety.

[0039] As Figure 10 and Figure 11As shown in the figure, it further includes a U-shaped frame 22, a rubber sheet 23 and a handle 24. A U-shaped frame 22 is slidably sleeved between the rear ends of four screws 3. Rubber sheets 23 are symmetrically connected to the upper and lower sides of the front side of the U-shaped frame 22, and the rubber sheets 23 are clamped between the rear ends of the screws 3 and the cross arm 1 at the rear side. Two handles 24 are connected to the middle of the rear side of the U-shaped frame 22. Before climbing the utility pole 001, workers can first sleeve the U-shaped frame 22 on the rear ends of the screws 3. Since the rubber sheets 23 are clamped between the rear ends of the screws 3 and the cross arm 1 at the rear side, the U-shaped frame 22 and the rubber sheets 23 can remain stable and will not fall off. During the process of tightening the bolt 4 by the workers, since the inner wall of the U-shaped frame 22 contacts the top and bottom of the rear ends of the screws 3, the rotation of the screws 3 following the bolt 4 can be prevented, facilitating the workers to tighten the bolt 4. There is no need for the workers to manually limit the screws 3, which can reduce the complexity of the operation and improve the work efficiency.

[0040] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
