Self-adaptive electric power concrete pole hoop

Abstract

The self-adaptive electric power concrete pole hoop comprises a hoop plate, a fastener and a plurality of inner liner plates, the hoop plate is of an annular opening structure, and connecting parts are arranged at the two ends of the hoop plate respectively; the fastener is connected with the connecting part and is used for adjusting the opening size of the hoop plate; and the plurality of inner liner plates sequentially surround and abut against the inner wall of the hoop plate at intervals. According to the self-adaptive electric power concrete pole hoop provided by the utility model, the sectional type inner liner plates are arranged, so that gaps exist among the arc-shaped sections, and when the hoop is tightened, each section can generate micro adjustment according to the outer diameter and local contour difference of the electric power concrete pole, so that the self-adaptive fitting of conical electric poles with different diameters is realized; and through multi-point contact of circumferential stress, each arc-shaped subsection bears partial load, so that the pressure applied to the surface of the telegraph pole by the hoop is effectively dispersed, the problem that local stress concentration is easily generated by a traditional integral lining structure is avoided, and the fixing stability is remarkably improved.

Description

Technical Field

[0001] This utility model relates to the field of power installation auxiliary equipment technology, and in particular to an adaptive power cement pole clamp. Background Technology

[0002] Concrete poles are common foundation support components in power distribution lines, widely used for installing crossarms, switchgear, enclosures, and monitoring devices, among other auxiliary facilities. Clad clamps, as crucial components for securing equipment to the concrete poles, directly impact installation stability and operational safety through their structural performance.

[0003] In existing technologies, common power pole clamps mostly adopt an integral ring or open structure, using bolts to tighten and fix the pole. However, there are still many shortcomings in practical applications. First, because power poles are usually tapered, wider at the bottom than the top, while traditional clamps are mostly of uniform diameter, the fit between the clamp and the pole is insufficient, easily leading to localized contact and uneven stress, thus affecting overall stability. Second, existing clamps rely on a single tightening point for adjustment during installation, with a limited adjustment range, making it difficult to accommodate poles of different diameters and resulting in poor versatility.

[0004] Furthermore, traditional clamps often have a rigid contact structure on the inside, which can easily cause wear or indentation on the surface of the concrete pole under long-term stress or vibration. They may also slip under external forces, posing certain safety hazards. Moreover, some clamps lack effective limiting and guiding mechanisms in their structural design, making them prone to displacement or deformation during tightening, further reducing installation reliability.

[0005] Therefore, how to provide a clamping structure that can adapt to power cement poles of different diameters, improve the uniformity of bonding, and enhance structural stability has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this utility model is to provide an adaptive electric cement pole clamp to solve the problems of poor adaptability, uneven fit and insufficient stability of existing clamps.

[0007] The technical solution adopted by the adaptive power cement pole clamp disclosed in this utility model is as follows:

[0008] An adaptive power concrete pole clamp includes a clamp plate, fasteners, and multiple inner lining pads. The clamp plate has an annular opening structure, and each end of the clamp plate is provided with a connecting part. The fasteners connect the connecting parts and are used to adjust the opening size of the clamp plate. The multiple inner lining pads are arranged in sequence and spaced around the inner wall of the clamp plate.

[0009] As a preferred embodiment, the inner lining plate is made of a highly elastic material.

[0010] As a preferred embodiment, the inner lining plate has an n-shaped cross-section.

[0011] As a preferred embodiment, the inner lining plate is provided with an anti-slip strip at the end away from the hoop plate.

[0012] As a preferred embodiment, the number of inner lining pads is 3.

[0013] As a preferred embodiment, the inner wall of the hoop plate is provided with an annular positioning strip, which is located in the middle of the hoop plate; the outer wall of the inner lining plate is provided with a groove, into which the positioning strip is inserted.

[0014] As a preferred embodiment, the inner wall of the hoop plate is provided with two annular positioning strips, which form a limiting area, and the inner lining plate is inserted into the limiting area.

[0015] As a preferred embodiment, the connecting portion includes a curved limiting portion, and the sidewall of the limiting portion has a gap.

[0016] As a preferred embodiment, the fastener includes a rotating pin, a limiting kit, a screw, and a nut. The rotating pin and the limiting kit are respectively located in two limiting portions. The two gaps correspond to the middle of the rotating pin and the middle of the limiting kit, respectively. One end of the screw is fixed to the side wall of the rotating pin, and the other end of the screw passes through the gap and the limiting kit in sequence to connect with the nut.

[0017] As a preferred embodiment, the connecting part is a fixing ear, the fixing ear has a through hole, and the fastener passes through the through hole for fixing.

[0018] The beneficial effects of the adaptive power concrete pole clamp disclosed in this utility model are as follows: it includes a clamp plate, fasteners, and multiple inner lining plates. The clamp plate has an annular opening structure, and each end of the clamp plate has a connecting part. The fasteners connect to the connecting parts and are used to adjust the opening size of the clamp plate. The multiple inner lining plates are arranged in sequence, spaced apart, and contact the inner wall of the clamp plate. By setting segmented inner lining plates, gaps are created between each arc-shaped segment. When the clamp is tightened, each segment can make slight adjustments according to the outer diameter and local contour differences of the power concrete pole, thereby achieving adaptive fitting for poles of different diameters and tapered poles. Furthermore, the segmented structure changes the circumferential force from a single rigid contact to a multi-point contact, with each arc-shaped segment bearing a portion of the load, thereby effectively dispersing the pressure applied to the surface of the power pole by the clamp and avoiding the local stress concentration problem that is prone to occur in traditional integral inner lining structures, significantly improving the stability of the fixation.

[0029] Please refer to Figure 1-3 An adaptive electric concrete pole clamp includes a clamp plate 10, a fastener 20, and multiple inner lining plates 30.

[0030] The hoop 10 has an annular opening structure, and connecting parts 11 are provided at both ends of the hoop 10.

[0031] The fastener 20 connects to the connecting part 11 and is used to adjust the opening size of the hoop 10.

[0032] Multiple inner lining plates 30 are arranged in sequence at intervals around the inner wall of the top contact plate 10.

[0033] By setting segmented inner lining plates 30, gaps are created between each arc-shaped segment. When the clamp is tightened, each segment can make slight adjustments based on the outer diameter and local contour differences of the power cement pole, thereby achieving adaptive fitting for poles of different diameters and tapered shapes.

[0034] Furthermore, the segmented structure transforms the circumferential force from a single rigid contact to a multi-point contact, with each arc-shaped segment bearing a portion of the load. This effectively disperses the pressure applied to the pole surface by the clamp, avoiding the localized stress concentration problem that is prone to occur in traditional integral lining structures, and significantly improving the stability of the fixation.

[0035] The hoop plate 10 has an annular opening structure, and each end of the hoop plate 10 is provided with a connecting part 11; the fastener 20 connects to the connecting part 11 and is used to adjust the opening size of the hoop plate 10. Multiple inner lining plates 30 are arranged in sequence at intervals around the inner wall of the hoop plate 10.

[0036] Preferably, the inner lining plate 30 is made of a highly elastic material.

[0037] The inner lining plate 30 has an n-shaped cross-section. After the hoop 10 is tightened, this structure will press the top towards the utility pole. After the hoop is fixed, the n-shaped structure of the inner lining plate 30 will rebound and touch the hoop 10 and the utility pole respectively, thereby improving the stability of the fixation.

[0038] The inner lining plate 30 is provided with an anti-slip strip at the end away from the hoop plate 10, which further improves the overall anti-slip effect. In this embodiment, a rubber strip is preferred.

[0039] Preferably, the number of inner lining pads 30 is 2-5 pieces, and in this embodiment, the number of inner lining pads 30 is preferably 3 pieces.

[0040] Preferably, the inner wall of the hoop plate 10 is provided with an annular positioning strip 14, which is located in the middle of the hoop plate 10; the outer wall of the inner lining plate 30 is provided with a groove, into which the positioning strip 14 is engaged. This structure can effectively prevent the inner lining plate 30 from slipping out of the hoop plate 10.

[0041] Preferably, the connecting portion 11 includes a curled limiting portion 12, the side wall of which has a gap 13. That is, a slit is pre-stamped into the connecting portion 11, then the connecting portion 11 is curled in the opposite direction to form a ring structure, and fixed by welding. This is a single-piece structure, which improves overall strength.

[0042] The fastener 20 includes a rotating pin 21, a limiting kit 22, a screw 23, and a nut 24. The rotating pin 21 and the limiting kit 22 are respectively located in two limiting portions 12. The two gaps 13 correspond to the middle of the rotating pin 21 and the middle of the limiting kit 22, respectively. One end of the screw 23 is fixed to the middle side wall of the rotating pin 21, and the other end of the screw 23 passes through the gap 13 and the limiting kit 22 in sequence and is connected to the nut 24.

[0043] Example 2:

[0044] Please refer to Figure 4 In this embodiment, based on Embodiment 1, two annular positioning strips 15 are provided on the inner wall of the hoop plate 10. The two positioning strips 15 form a limiting area, and the inner lining plate 30 is inserted into the limiting area. The two positioning strips 15 restrict the sliding of the inner lining plate 30, making its mating structure more stable.

[0045] Example 3:

[0046] This embodiment, based on Embodiment 1, sets the connecting part as a fixed ear structure. A through hole is provided in the fixed ear, through which the fastener passes for fixation. Specifically, the fastener is a fastening screw passing through the through hole, with a fastening nut rotating and locking onto the fastening screw. (This structure is a common fixing structure for clamps, and will not be described in detail in this embodiment.) This type of structure has relatively low production costs and can enhance market competitiveness.

[0047] This utility model provides an adaptive electric concrete pole clamp, including a clamp plate, fasteners, and multiple inner lining plates. The clamp plate has an annular opening structure, with connecting portions at both ends. The fasteners connect to the connecting portions and are used to adjust the opening size of the clamp plate. The multiple inner lining plates are arranged in a staggered manner around the inner wall of the clamp plate. By setting segmented inner lining plates, gaps are created between the arc-shaped segments. When the clamp is tightened, each segment can make slight adjustments according to the outer diameter and local contour differences of the electric concrete pole, thereby achieving adaptive fitting for poles of different diameters and tapered shapes. Furthermore, the segmented structure changes the circumferential force from a single rigid contact to multi-point contact, with each arc-shaped segment bearing a portion of the load, effectively dispersing the pressure applied to the pole surface by the clamp and avoiding the local stress concentration problem easily caused by traditional integral inner lining structures, significantly improving the stability of the fixation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
