Description

Technical Field

[0001] This invention relates to an auxiliary tool for power construction, specifically an anti-tipping power line support frame. Background Technology

[0002] In scenarios such as industrial equipment maintenance, production line technical upgrades, and emergency repairs for sudden malfunctions, temporary power lines are core infrastructure ensuring the normal operation of equipment such as power tools and testing instruments. Their rationale and safety directly determine work efficiency and the safety of on-site personnel. To avoid risks such as crushing damage, insulation aging, and tripping hazards caused by laying temporary power lines directly on the ground, the industry commonly uses support frames to support the power lines overhead. Currently, the most widely used type is the simple tripod-style power line support frame.

[0003] With the increasing demands of large-scale maintenance, cross-regional technical upgrades, and emergency repairs in complex environments, the existing simple tripod-type support frames have gradually revealed several key defects, making them unsuitable for high safety standards and complex operating conditions. Firstly, the existing simple tripods rely solely on the natural limiting force of the pole surface to suspend the power cord, without any dedicated clamping or fixing structures. When personnel walk on site, equipment moves, or there is a slight external impact, the power cord is prone to shifting or slipping off the pole. This could not only lead to sudden power outages and interruptions, but also create tripwires on the ground, causing falls and other safety accidents. Furthermore, if the shifted power cord is not promptly reset, it may come into contact with high-temperature equipment or sharp parts, increasing the risk of insulation damage and leakage, making it difficult to completely eliminate potential safety hazards on site.

[0004] Secondly, their anti-tipping capabilities are weak, and they cannot withstand interference from complex environments. Simple tripods are mostly made of lightweight aluminum alloy or engineering plastics, resulting in a light overall weight but a high center of gravity. In outdoor maintenance or high-wind-speed work environments, they are easily tipped over by wind. Furthermore, the fixed leg lengths cannot be adjusted to accommodate common uneven ground surfaces or gaps between tiles at the work site, causing some legs to dangle and further reducing stability. If a tipped-over tripod is not detected promptly, it can create a subtle but significant safety hazard for subsequent operations.

[0005] Furthermore, the tripods have poor adaptability, making it difficult to meet diverse operational needs. The fixed support height of existing tripods prevents flexible adjustment based on factors such as the height of power cord and equipment interfaces, and the distribution of obstacles on site. When it's necessary to accommodate equipment interfaces of different heights or avoid obstacles like ground pipes and toolboxes, frequent replacement of tripods with different specifications is required. This is not only cumbersome but also necessitates storing multiple sets of equipment of different sizes, increasing warehousing and management costs.

[0006] Furthermore, the lack of scene adaptability reduces the convenience of operation in complex environments. In nighttime maintenance or emergency repair scenarios in dimly lit underground workshops or equipment rooms, the simple tripod lacks any lighting auxiliary structure, making it difficult for operators to clearly observe the power line connection status and whether the support frame is loose or tilted. This not only reduces the efficiency of safety inspections but may also cause potential risks to be overlooked due to blind spots. At the same time, its single support function cannot provide additional assistance for on-site operations and is difficult to adapt to the high efficiency and safety requirements of modern maintenance operations.

[0007] In summary, existing simple tripod-type power cord support frames have significant shortcomings in terms of power cord fixation stability, anti-tipping capability, high flexibility, and scene adaptability. There is an urgent need for a power cord support frame with a stable fixing structure, strong anti-tipping performance, flexible adjustment function, and scene assistance capabilities to solve the pain points of existing technologies and ensure on-site operation safety and efficiency. Summary of the Invention

[0008] The purpose of this invention is to provide an anti-tipping power cord support frame. The power cord is secured by a movable clamp within the mounting base, which, under the action of a spring, wraps around the power cord. A lever clamping mechanism, which drives a butterfly knob and clamping block downwards, creates a double-fixed structure. A triangular stable support is formed by a first hinge seat, a second hinge seat, support legs, and a connecting rod. An adjusting screw finely adjusts the length of the support legs to fit the ground. A weight plate and weight blocks lower the center of gravity to prevent tipping. The height of the mounting base can be adjusted via the clamping handle, and an auxiliary lighting lamp provides illumination, ensuring safe fixing of the power cord and stable operation of the support frame.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A power cord support frame for preventing tipping includes a support frame rod, on which a mounting base is fixedly installed. The mounting base is a U-shaped base. The support frame rod is characterized by having an elbow clamping mechanism fixedly installed on its side. The clamping part of the elbow clamping mechanism has a threaded hole that extends vertically. A butterfly knob is threaded into the threaded hole. The knob part of the butterfly knob is located on the upper side, and the screw part is located on the lower side. A clamping block is rotatably installed on the bottom side of the screw part of the butterfly knob. The bottom side of the clamping block has an arc-shaped groove. The first hinge seat is fixedly installed on the bottom side of the support frame rod, and the second hinge seat is slidably connected to the rod. Both the first hinge seat and the second hinge seat have three or more hinge components on their outer periphery. Each hinge component on the second hinge seat has a support leg rotatably installed on it, with the rotatable installation point close to the top of the support leg. Each hinge component on the first hinge seat has a connecting rod rotatably installed on it, and the other end of the connecting rod is rotatably connected to the middle of the support leg.

[0010] The space in the recessed part of the mounting base is larger than the volume of the clamping block.

[0011] The mounting base has a mounting groove with its bottom surface facing downwards. The mounting groove is fitted with a movable gripper that rotates in the middle. The rotating part of the movable gripper is simultaneously rotated and installed inside the mounting groove. The gripping part of the movable gripper extends to both sides with extension parts. Springs are fixedly installed at the bottom of the two side extension parts, and the other end of the springs is fixedly installed to the bottom surface of the mounting groove.

[0012] The movable gripper consists of two arc-shaped clamping parts connected by the same rotating shaft.

[0013] The support leg has a threaded hole seat and a guide hole seat arranged sequentially from top to bottom on the side away from the support frame rod. An adjusting screw is threaded on the threaded hole seat, and an extended support leg is rotatably connected to the bottom of the adjusting screw. The extended support leg is slidably guided and installed into the guide hole of the guide hole seat.

[0014] The adjusting screw is provided with a screw cap at the top, and the support leg is provided with a clearance groove on the moving path of the screw cap.

[0015] The support frame rod body is provided with a cavity, and the bottom of the mounting base extends with an extension rod. The extension rod of the mounting base is fitted and inserted into the cavity of the support frame rod body. The side of the support frame rod body is provided with a threaded hole that extends into the cavity. A clamping handle is threaded into the threaded hole. The clamping handle is screwed into the support frame rod body to tighten or loosen the extension rod extending from the bottom of the mounting base.

[0016] The bottom of the support frame rod is provided with a weight plate, and several weight blocks can be detachably installed on the weight plate.

[0017] The weighting plate is disc-shaped, and its upper part is connected to the bottom of the support frame rod through a rectangular rod. The weight block is annular disc-shaped, and its inner ring is provided with a slot for connecting to the outside. The width of the slot is the same as the thickness of the rectangular rod, and the diameter of the inner ring of the weight block is the same as the width of the rectangular rod. The weight block passes through the slot and is placed on top of the weighting plate, and is rotated 90 degrees to prevent it from falling.

[0018] A light is installed at the bottom of the weighting plate, and the light is equipped with a built-in battery.

[0019] This support frame achieves safe overhead and anti-tipping protection for temporary power lines through the coordinated operation of multiple components. The specific mechanism is as follows: First, in the power cord securing stage, after placing the power cord in the recessed area of ​​the U-shaped mounting base, the movable gripper, under the contraction force of the springs at the bottom of the two extensions, transmits the force through the extensions to the rotating shaft, causing the two arc-shaped clamping parts to converge towards the center, wrapping the power cord within the enclosed arc-shaped space to form a wrapping fixation. Simultaneously, the elbow clamping mechanism is operated to adjust its clamping part above the power cord. Rotating the butterfly knob in the threaded hole of the clamping part clockwise pushes the screw of the butterfly knob downwards, causing the bottom rotating clamping block to move downwards synchronously. The arc-shaped groove on the bottom side of the clamping block conforms to the outer wall of the power cord, forming an upper clamping force, which, together with the lower wrapping shape of the movable gripper... The system features dual fixation through upper and lower clamping and lateral limiting. The recessed space of the mounting base is larger than the volume of the clamping block, providing ample room for downward clamping to avoid component interference. In the support and anti-tipping mechanism, the second hinged seat slides upwards along the support frame rod. At least three outriggers hinged to its outer periphery open outwards synchronously as the hinge points move upwards. Simultaneously, the connecting rod hinged to the outer periphery of the first hinged seat fixed to the bottom of the support frame rod, with one end rotatably connected to the middle of the outrigger, extends synchronously with the outrigger opening, forming a triangular stable structure. This even distribution of multiple support points expands the support area to reduce the risk of tipping. If the working surface is uneven, the screw cap at the top of the adjusting screw on the outrigger can be rotated to allow the adjusting screw to move along the threaded hole. The threaded seat moves up and down, causing the extended support legs connected to the bottom to slide along the guide holes of the guide hole seat, achieving fine-tuning of the overall length of the support legs and ensuring that the bottom of all support legs touch the ground stably. The clearance grooves on the support legs provide space for the movement of the screw nut to avoid interference. At the same time, the bottom of the support frame rod is connected to a disc-shaped weight plate via a rectangular rod. Annular disc-shaped weight blocks can be added according to the requirements of on-site wind force, power cord weight, etc. The weight block is placed above the weight plate after passing through the inner ring slot into the rectangular rod and then rotated 90°. Utilizing the dimensional adaptability of the slot width being the same as the thickness of the rectangular rod and the inner ring diameter being the same as the width of the rectangular rod, the weight block is secured to both sides of the rectangular rod to prevent slippage. The weight at the bottom lowers the center of gravity of the support frame, further resisting tipping caused by wind or external impacts. During the scene adaptation process, if it is necessary to adjust the overhead height of the power cord, the clamping handle in the threaded hole on the side of the support frame rod that leads to the cavity can be loosened, and the extension rod at the bottom of the mounting base can be moved up and down along the cavity of the support frame rod. After the height is adapted, the clamping handle can be tightened again to press against the extension rod to fix the position. The bottom of the weight plate is equipped with a built-in battery-powered light, which can provide local lighting in dimly lit maintenance or emergency repair scenarios, helping operators to check the power cord connection status and the stability of the support frame. Ultimately, it achieves the overall operational effect of safe power cord fixation, stable support structure to prevent tipping, and functional adaptation to multiple scene needs.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. More secure power cord fixation, eliminating tripping hazards: Existing simple tripods do not have a power cord fixing function, which often leads to tripping risks due to power cord displacement. However, this invention uses a "movable clamp + spring" under the mounting base for a wrap-around clamping, combined with an elbow clamping mechanism, a butterfly knob and the upper side of the clamping block for clamping, forming a double fixing structure of "upper and lower clamping + lateral limiting". It can closely fit the outer wall of the power cord, effectively preventing the power cord from shifting or falling off, and completely eliminating the illegal hazard of tripping. 2. Significantly improved anti-tipping capability, adaptable to complex environments: Existing simple tripods are lightweight and have weak ground grip, making them prone to tipping over due to wind or uneven ground. This invention enhances anti-tipping performance through multi-dimensional design. First, it uses three or more outriggers in conjunction with connecting rods and hinged seats to form a stable triangular support of "rod body-outrigger-connecting rod," expanding the support area and reducing the risk of tipping over. Second, the length of the outriggers can be finely adjusted by adjusting screws and extending the outriggers to ensure that all outriggers touch the ground smoothly on uneven ground, preventing tilting. Third, it is equipped with a detachable weight plate and weight blocks, which can increase the weight at the bottom as needed and lower the center of gravity, effectively resisting tipping caused by wind or external impacts, adapting to different on-site environments. 3. Adjustable height to adapt to various operational needs: Existing simple tripods have a fixed height, which is difficult to adapt to the power line requirements of different overhead heights. This invention, through the cavity structure of the support frame, the extension rod of the mounting base and the clamping handle, can flexibly adjust the height of the mounting base, thereby adjusting the overhead height of the power line to meet the power line layout needs of different operational scenarios in large-scale maintenance, technical upgrades and emergency repairs. 4. Enhanced operational convenience by adding auxiliary functions: Existing simple tripods lack auxiliary functions, making it difficult to check the power cord and support frame status in dim lighting conditions. This invention incorporates a built-in battery-powered light at the bottom of the weight plate, providing localized illumination in low-light environments. This helps operators check the power cord connection status and support frame stability in a timely manner, further ensuring operational safety and efficiency. Simultaneously, the design of each component balances practicality and stability. For example, the arc-shaped structure of the movable gripper adapts to the shape of the power cord, the clearance grooves on the legs prevent interference during adjustment, and the slotted weight block fits the rectangular rod to prevent slippage. The overall structure is both practical and reliable, better adapting to complex on-site operating conditions. Attached Figure Description

[0022] The technical solutions of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, an anti-tipping power cord support frame includes a support frame rod 1, on which a mounting base 2 is fixedly installed. The mounting base 2 is a U-shaped base. The feature is that an elbow clamping mechanism 3 is fixedly installed on the side of the mounting base 2. The clamping part 31 of the elbow clamping mechanism 3 is provided with a threaded hole that runs vertically through the upper and lower parts. A butterfly knob 4 is threadedly connected to the threaded hole. The knob part of the butterfly knob 4 is located on the upper side, and the screw part is located on the lower side. A clamping block 5 is rotatably installed on the bottom side of the screw part of the butterfly knob 4. The bottom side of the clamping block 5 is provided with an arc-shaped groove. The support frame rod 1 is fixedly installed with a first hinge seat 61 on its bottom side, and a second hinge seat 62 is slidably connected to the rod. Both the first hinge seat 61 and the second hinge seat 62 are provided with three or more hinge members 63 on their outer periphery. Each hinge member 63 on the second hinge seat 62 is rotatably mounted with a support leg 7, and the rotatable mounting point is close to the top of the support leg 7. Each hinge member 63 on the first hinge seat 61 is rotatably mounted with a connecting rod 8, and the other end of the connecting rod 8 is rotatably connected to the middle of the support leg 7.

[0024] The space in the recessed part of the mounting base 2 is larger than the volume of the clamping block 5.

[0025] The mounting base 2 has a mounting groove 21 with its bottom surface facing downward. The mounting groove 21 is equipped with a movable gripper 22 that rotates in the middle. The rotating part of the movable gripper 22 is simultaneously rotated and installed inside the mounting groove 21. The gripping part of the movable gripper 22 extends to both sides with extension parts 23. Springs 24 are fixedly installed at the bottom of the two side extension parts 23. The other end of the springs 24 is fixedly installed to the bottom surface of the mounting groove 21.

[0026] The movable gripper 22 consists of two arc-shaped clamping parts connected by the same rotating shaft.

[0027] On the side of the support leg 7 away from the support frame rod 1, a threaded hole seat 71 and a guide hole seat 72 are arranged sequentially from top to bottom. An adjusting screw 73 is threadedly installed on the threaded hole seat 71. An extended support leg 74 is rotatably connected to the bottom of the adjusting screw 73. The extended support leg 74 is slidably guided and installed into the guide hole of the guide hole seat 72.

[0028] The top of the adjusting screw 73 is provided with a screw cap 75, and the support leg 7 is provided with an avoidance groove 76 on the moving path of the screw cap 75.

[0029] The support frame rod 1 has a cavity inside, and the mounting base 2 has an extension rod extending from its bottom. The extension rod of the mounting base 2 is inserted into the cavity of the support frame rod 1. The support frame rod 1 has a threaded hole that extends into the cavity. A clamping handle 11 is threaded into the threaded hole. The clamping handle 11 is screwed into the support frame rod 1 to tighten or loosen the extension rod extending from the bottom of the mounting base 2.

[0030] The bottom of the support frame rod 1 is provided with a weight plate 12, and several weight blocks 13 can be detachably installed on the weight plate 12.

[0031] The weighting plate 12 is disc-shaped and connected to the bottom of the support frame rod 1 via a rectangular rod. The weight block 13 is annular disc-shaped with a slot in its inner ring for connecting to the outside. The width of the slot is the same as the thickness of the rectangular rod, and the diameter of the inner ring of the weight block 13 is the same as the width of the rectangular rod. The weight block 13 passes through the slot and is placed above the weighting plate 12, and rotates 90 degrees to prevent it from falling.

[0032] The bottom of the weighting plate 12 is equipped with a light 9, which has a built-in battery.

[0033] The specific implementation steps are as follows: The assembled support frame is transported to the power line laying position at the work site. The temporary power line is first placed in the concave area of ​​the mounting base 2. At this time, the two arc-shaped clamping parts of the movable clamp 22 automatically converge towards the center and wrap around the outer wall of the power line under the contraction force of the spring 24. The inner wall of the arc-shaped clamping part is tightly attached to the power line. Then, the handle of the elbow clamping mechanism 3 is operated to push the clamping part 31 to the corresponding position above the power line. The butterfly knob 4 is rotated clockwise to make its screw part slowly move down along the threaded hole of the clamping part 31, driving the clamping block 5 to press down synchronously until the arc-shaped groove on the bottom side of the clamping block 5 completely fits the top outer wall of the power line, forming a double fixation of the lower side of the movable clamp wrapping and the upper side of the clamping block pressing down.

[0034] Next, the support structure is unfolded and adapted to the ground. The second hinge seat 62 is pushed upward along the support frame rod 1. At this time, the outrigger 7 on the second hinge seat 62 opens outward synchronously with the hinge point moving upward. At the same time, the connecting rod 8 connected to the first hinge seat 61 extends synchronously with the outrigger opening until the bottom of the outrigger contacts the ground and the connecting rod is in a taut state. At this time, the three outriggers are evenly distributed radially, maximizing the support area. If the working ground is uneven, causing some outriggers to be suspended, the adjustment structure can be operated for the suspended outriggers: rotate the screw cap 75 on the top of the threaded hole seat 71 on the outrigger 7, so that the adjusting screw 73 moves downward along the internal thread of the threaded hole seat 71, driving the extended outrigger 74 connected to the bottom to slide vertically down along the guide hole of the guide hole seat 72 until the bottom of the extended outrigger touches the ground. During this period, the screw cap 75 moves along the clearance groove 76 on the outrigger 7. Repeat this operation until all three outriggers, including the extended outrigger, touch the ground smoothly, and the entire support frame remains in a vertical state.

[0035] Subsequently, additional weights are added to enhance the anti-tipping performance: Based on the on-site wind conditions or the weight of the power cord, an appropriate number of annular disc-shaped weights 13 are selected. The weights 13 are aligned with the rectangular rod at the bottom of the support frame rod 1 through the inner ring slot, and placed on top of the weight plate 12 after passing through the slot and through the rectangular rod. The weights 13 are rotated 90° clockwise. At this time, because the width of the slot is consistent with the thickness of the rectangular rod and the diameter of the inner ring is consistent with the width of the rectangular rod, the weights are locked on both sides of the rectangular rod and cannot slide down the rod. By increasing the weight at the bottom, the center of gravity of the support frame is significantly lowered, which can effectively resist the risk of tipping caused by wind or slight external impact.

[0036] Finally, adjust the height and activate the auxiliary functions. If it is necessary to adjust the overhead height of the power cord to avoid ground obstacles or adapt to the equipment interface, loosen the clamping handle 11 on the side of the support frame rod 1, and move the extension rod of the mounting base 2 up and down along the cavity of the rod to drive the power cord to rise and fall synchronously. After the required height is reached, tighten the clamping handle 11 clockwise again so that its end is pressed against the outer wall of the extension rod to fix the position of the mounting base. If the working scene is dimly lit, turn on the switch of the bottom light 9 of the weight plate 12. Its built-in battery can provide continuous lighting, which makes it convenient for operators to check the power cord connection status, the fixation of the clamp and the movable clamp, and the ground contact stability of the outriggers in real time, ensuring that the support frame is always in a safe operating state throughout the entire operation.
