Description

Technical Field

[0001] The present invention relates to the technical field of electric power auxiliary tools, and is a movable multi-functional insulating bracket. Background Art

[0002] When carrying out complex distribution network live working projects, equipment such as bypass cable hanging rods and insulating rods need to be subjected to insulation resistance detection on site before use to ensure operation safety. When performing insulation resistance detection, in order to ensure accurate test results, it is necessary to suspend and place tools such as bypass cable hanging rods and insulating rods, and a certain distance needs to be ensured between different tools and between each phase of bypass cables. At the live working site, insulating rods and rigid shielding covers are often directly placed on moisture-proof cushion cloth. When there are many working tools or the moisture-proof cushion cloth is not clean, it is easy to cause dirt or scratches on the surfaces of insulating rods, rigid shielding covers, etc., posing a hidden danger to operation safety.

[0003] Chinese document with publication number CN219417548U discloses an insulating bracket for insulating tool testing, which includes two groups of gantry mounting frames. The tops of the two groups of gantry mounting frames are hinged and installed to form a ladder structure. A number of support rods are arranged side by side on the gantry mounting frames, and the support rods on both sides of the gantry mounting frames are horizontally corresponding to each other in pairs; a anti-rolling device is slidably connected to the support rods. A sliding groove is arranged on the support rods, and wavy locking teeth are arranged on both sides of the sliding groove. The anti-rolling device includes a fixing plate, and an installation piece is fixedly connected to the bottom of the fixing plate. Compression springs are arranged on both sides of the installation piece; a number of convex locking pieces that cooperate with the locking teeth to slide are arranged at the opposite ends of the two compression springs. The fixing plate is slidably connected to the support rod through the cooperation between the locking teeth and the convex locking pieces. Through a number of support rods arranged on the gantry mounting frame, long insulating rods can be horizontally placed or insulating ropes can be hung, etc., which can effectively isolate the insulating tools from the ground. And because the gantry mounting frames are hinged and installed to form a ladder structure, the distance between the support rods arranged from top to bottom becomes larger from small, which can meet the needs of different insulating tools. However, it is inconvenient to move, requires manual handling and relocation, has too high a center of gravity and cannot adjust the height and width of the insulating bracket according to the space environment of the operation site.

[0004] At the live working site, the existing insulating brackets are inconvenient to carry, their height cannot be adjusted, their stability is insufficient, and their environmental adaptability is poor. Therefore, during actual power construction, mostly insulating items such as insulating stools and wooden blocks are still used to temporarily support tools such as cable construction operating rods so as to keep the power tools at a distance from the ground.

[0025] In the above technical solution, in order to make the center of gravity of the present invention stable, the two bases 2 and the two herringbone insulating frames can be symmetrically arranged left and right; in order to facilitate the rotational installation of the upper end of the front column 4 and the upper end of the rear column 5, the upper ends of the front column 4 and the rear column 5 can both be in the shape of a sheet or a plate; in order to achieve better insulation, the surfaces of the two bases 2 and the herringbone insulating frame can be provided with an insulating coating, such as an insulating paint layer and an insulating glue layer, etc., or can be directly processed from glass fiber or engineering plastics with excellent insulating performance or other insulating materials with good mechanical properties well-known in the art in the prior art, and an insulating rubber layer can also be laid on the surfaces of the above components.

[0026] The lower end of the chevron-shaped insulating frame can be movably installed on the corresponding base 2 through a linear guide with two sliders. The lower ends of the front column 4 and the rear column 5 can be hinged to the upper sides of the corresponding sliders through hinge seats. It can also be realized by providing a dovetail groove or a T-shaped groove on the base 2, and two complementary-shaped sliders are slidably installed in the dovetail groove or the T-shaped groove. The upper ends of the two sliders are respectively rotatably installed with the lower ends of the corresponding front column 4 or the rear column 5, so as to change the opening angle of the chevron-shaped insulating frame without affecting the front-back relative movement between the chevron-shaped insulating frame and the base 2.

[0027] According to requirements, all four casters 3 can be Fuma casters in the prior art, or two of them can be fixed wheels and the other two can be universal wheels. To facilitate fixing the position of the present invention, at least one of the four casters 3 is provided with a brake, and for easy operation, the brake can be a foot brake. The cross beam 1 and the base 2 can be slidably installed through a linear guide, a sliding sleeve sleeved outside the cross beam 1, etc. It can also be realized by a dovetail cross beam 1 or a T-shaped cross beam 1, and a chute complementary to the shape of the cross beam 1 provided on the base 2. A locking part for limiting the relative position between the cross beam 1 and the corresponding base 2 is provided, such as a vertical elbow clamp or a locking bolt 30, etc.

[0028] A horizontally telescopic rod that can be telescoped left and right is fixedly installed between the two rotating shafts 6. A number of insulating hook rods for hooking power tools are fixedly installed at intervals left and right on the horizontally telescopic rod.

[0029] In the above technical solution, the horizontally telescopic rod can be directly realized by an insulating telescopic rod in the prior art; it can also be realized by an inner sleeve rod and an outer sleeve tube sleeved inside and outside each other. A locking part can be provided between the inner sleeve rod and the outer sleeve tube. The locking part can be realized by a number of through holes that penetrate inside and outside and are distributed along the length direction provided on the outer sleeve tube and a ball head / cylindrical head spring plunger fixedly installed on the inner sleeve rod; it can also be realized by a hollow outer sleeve tube, a gear fixedly installed inside the outer sleeve tube, a rack that can be meshed with the gear, and a ratchet anti-backlash mechanism for locking the relative positions of the gear and the rack. The gear can be rotated by a handle to make the rack telescopic left and right. When the rotation stops, the ratchet anti-backlash mechanism can fix the telescopic length of the rack. In addition, the horizontally telescopic rod can also be used to hang an insulating hanger so as to hang the insulating clothing on the present invention.

[0030] The insulating hook rod can be realized by an insulating hanging rod with a hook at the end in the prior art, or by an insulating hanging rod with an anti-detachment stop piece at the end. The insulating hook rod can hook power tools, such as a bypass cable hanging rod 35, an insulating rope 38, etc.

[0031] According to requirements, to achieve better insulation, the insulating hook rod and the surface of the transverse telescopic rod at the position where the insulating hook rod is installed may be provided with an insulating coating, such as an insulating paint layer and an insulating adhesive layer, etc., or an insulating rubber layer may be laid on the surface of the above-mentioned components. The insulating hook rod and the transverse telescopic rod may also be directly processed from glass fiber, engineering plastics with excellent insulating properties, or other insulating materials with good mechanical properties well-known in the art in the prior art.

[0032] During use, when the front column 4 and the rear column 5 rotate towards each other along the rotating shaft 6, as the angle between the front column 4 and the rear column 5 continuously decreases, the height of the herringbone insulating frame continuously increases, making the overall height of the present invention continuously increase; when the front column 4 and the rear column 5 rotate away from each other along the rotating shaft 6, as the angle between the front column 4 and the rear column 5 continuously increases, the height of the herringbone insulating frame continuously decreases, making the overall height of the present invention continuously decrease, thereby realizing the adjustment of the overall height of the present invention.

[0033] When the two bases 2 slide towards each other along the cross beam 1 or one of the bases 2 slides towards the other base 2 along the cross beam 1, the distance between the two bases 2 continuously decreases. At this time, by simultaneously shortening the length of the transverse telescopic rod, the distance between the two herringbone insulating frames can be reduced, making the overall width of the present invention decrease; when the two bases 2 slide away from each other along the cross beam 1 or one of the bases 2 slides away from the other base 2 along the cross beam 1, the distance between the two bases 2 continuously increases. At this time, by simultaneously lengthening the length of the transverse telescopic rod, the distance between the two herringbone insulating frames can be increased, making the overall width of the present invention increase.

[0034] Through the above method, the overall height and width of the present invention can be adjusted according to actual needs. For example, increasing the height of the present invention and reducing the width of the present invention enables the present invention to be applied to narrow spaces; reducing the height of the present invention enables the present invention to be applied to low spaces; enabling the present invention to be applicable to different working environments and improving the flexibility of use of the present invention.

[0035] A plurality of front insulating rods are provided at intervals up and down on the side of the front column 4 facing away from the transverse telescopic rod, and corresponding rear insulating rods are provided on the rear column 5 at positions corresponding to each front insulating rod.

[0036] In the above technical solution, the front insulating rods and the rear insulating rods are arranged in pairs and act together to support rod-shaped or bar-shaped electric power tools of different lengths (i.e., various operating rods used in the process of cable construction, referred to as bar-shaped tools, the same below), such as insulating rods, bypass cable brackets, grounding rods 36, etc. To prevent the bar-shaped tools from falling during movement, the front insulating rods and the rear insulating rods can both be inclined upwards, that is, the angle with the ground is greater than 90°, and anti-drop baffles can also be fixedly installed at their ends. The structures of the front insulating rods and the rear insulating rods may be the same or different.

[0037] According to requirements, to achieve better insulation, the surfaces of the front insulating rod and the rear insulating rod may be provided with insulating coatings, such as insulating paint layers and insulating adhesive layers, etc., or an insulating rubber layer may be laid on the surfaces of the above-mentioned components, or they may be directly processed from glass fiber, engineering plastics with excellent insulating properties, or other insulating materials with good mechanical properties well-known in the art in the prior art.

[0038] A driving part is provided between the lower part of each herringbone insulating frame and the upper side of the corresponding base 2. The driving part can drive the lower ends of the front column 4 and the rear column 5 to move towards or away from each other, so as to change the opening angle of the herringbone insulating frame, thereby adjusting the height of the movable multi-functional insulating bracket.

[0039] In the above technical solution, the driving part can be an electric push rod, a cylinder or a hydraulic cylinder driving system in the prior art. In the present invention, the herringbone insulating frame is an isosceles triangle, and the driving part can change the opening angle of the herringbone insulating frame, that is, change the apex angle of the isosceles triangle. When the apex angle of the isosceles triangle becomes larger, its height decreases, that is, the height of the herringbone insulating frame decreases; when the apex angle of the isosceles triangle becomes smaller, its height increases, that is, the height of the herringbone insulating frame increases.

[0040] During use, first move the present invention to the use position at the operation site, and then according to the environmental space size at the operation site, correspondingly adjust the height of the herringbone insulating frame through the driving part, so that the height of the present invention is adapted to the height size of the environmental space. Then, horizontally extend and retract the transverse telescopic rod left and right, and at the same time slide the two bases 2 left and right, so that the width of the present invention is adapted to the width size of the environmental space. Then move the present invention again, move the present invention to the designated position and fix it.

[0041] Place them on the front insulating rod and the rear insulating rod at the same height from top to bottom according to the length of the operating rod; then hang tools such as the bypass cable hanging rod 35 and the insulating rope 38 on the corresponding insulating hook rods.

[0042] The present invention can form a rectangular base through a cross beam 1 and two bases 2. The horizontal telescopic rod is installed on the rectangle through two herringbone insulating frames, so that the overall shape of the present invention is a lying triangular prism (i.e., the triangular bottom surface is perpendicular to the ground), and the center of gravity is closer to the ground, making the present invention have good stability by itself; when rod-shaped tools of different lengths are loaded onto the herringbone insulating frames from top to bottom, they can be automatically loaded in the order of shorter at the top and longer at the bottom, so that the center of gravity of the present invention after loading the tools still remains at a lower position and still has good stability, preventing the present invention from tipping over or toppling during use and avoiding affecting the use; by driving the lower ends of the front column 4 and the rear column 5 to move towards or away from each other, the opening angle of the herringbone insulating frame is changed, and thus the height of the present invention can be adjusted. By horizontally telescoping the horizontal telescopic rod and sliding the two bases 2 left and right at the same time, the width of the present invention can be adjusted, so that in addition to normal working conditions, the present invention can also be applicable to narrow space working conditions and low-height working conditions, with a wider range of applicability of the working environment and being able to better assist operators in quickly obtaining working tools at the construction site; the use of casters 3 makes the movement of the present invention more time-saving and labor-saving.

[0043] According to actual needs, the above-mentioned movable multifunctional insulating bracket can be further optimized or / and improved: Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figures 1 to 3 Figure 6, the insulating hook rod includes a stop strip 7, a sealing block 8, a guide shaft 9, a guide slider 10, a connecting rod 11, a return spring 12 and a hollow suspension sleeve 13. The rear end of the suspension sleeve 13 is fixedly installed at the corresponding position on the front side of the horizontal telescopic rod; a strip-shaped mounting hole 14 that penetrates inside and outside is provided on the upper side of the front part of the suspension sleeve 13. The stop strip 7 is rotatably installed inside the front part of the strip-shaped mounting hole 14, and the length of the stop strip 7 is less than the length of the strip-shaped mounting hole 14; a sealing block 8 is fixedly installed at the front end of the suspension sleeve 13, and a guide shaft 9 sleeved inside the suspension sleeve 13 is fixedly installed in the middle of the rear side of the sealing block 8. The rear end of the guide shaft 9 is fixedly installed at the front side of the horizontal telescopic rod; a guide slider 10 is sleeved on the outer side of the front part of the guide shaft 9, and a connecting rod 11 whose upper end is hinged to the lower side of the middle part of the stop strip 7 is hinged to the middle part of the upper side of the guide slider 10; a return spring 12 sleeved on the outer side of the front part of the guide shaft 9 is fixedly installed on the front side of the guide slider 10, and the front end of the return spring 12 is fixedly installed at the corresponding position on the rear side of the sealing block 8.

[0044] With such a setting, when the rear end of the retaining bar 7 is pulled forward, the retaining bar 7 rotates forward, pulling the upper end of the connecting rod 11 to move forward. The lower end of the connecting rod 11 then pulls the guiding slider 10 to slide forward along the guiding shaft 9. The guiding slider 10 compresses the return spring 12, causing the retaining bar 7 to open forward. After releasing the retaining bar 7, in addition to resetting under its own weight, the connecting rod 11 is also under the action of the backward spring restoring force of the return spring 12. The guiding slider 10 slides backward along the guiding shaft 9. The guiding slider 10 drives the lower end of the connecting rod 11 to move backward, and the upper end of the connecting rod 11 can also pull the retaining bar 7 downward, enabling the retaining bar 7 to clamp the power tool under the action of the spring restoring force (at this time, the spring pre-tightening force), preventing the power tool from sliding forward and preventing the power tool from falling.

[0045] During use, due to the support of the connecting rod 11 and the guiding slider 10, the rear end of the retaining bar 7 protrudes slightly above the upper surface of the suspension sleeve 13. After power tools such as the bypass cable hanging rod 35 or the insulating rope 38 are hung on the suspension sleeve 13, the operator can hold the rear end of the retaining bar 7 and rotate it forward to lift. After moving the power tools such as the bypass cable hanging rod 35 or the insulating rope 38 forward to the lower side of the rear part of the retaining bar 7, release the retaining bar 7. The retaining bar 7 rotates backward under the action of the return spring 12 and the connecting rod 11, and the bypass cable hanging rod 35, the insulating rope 38, the hard shielding cover and other power tools can be tightly fixed between the retaining bar 7 and the suspension sleeve 13 through the spring pre-tightening force, effectively preventing the power tools such as the bypass cable hanging rod 35, the insulating rope 38, and the hard shielding cover from falling off the front end of the suspension sleeve 13 during the movement of the present invention.

[0046] According to requirements, the rear end of the guiding shaft 9 can be fixedly installed with the transverse telescopic rod through welding, riveting, interference connection or threaded connection, etc. The front end of the guiding shaft 9 and the blocking 8 can be fixedly installed by means of drilling and welding, riveting, drilling and interference connection or drilling and installing nuts, etc.

[0047] Embodiment 3: As an optimization of the above embodiment, as shown in the appendix Figures 1 to 2As shown in Figures 4 and 6, the front insulating rod includes a fixed baffle 15, a guiding rod 16, a limiting slider 17, a sliding retaining ring 18 and a hollow support sleeve 19. One end of the support sleeve 19 is fixedly installed at the corresponding position on the side of the front column 4 away from the transverse telescopic rod; the other end of the support sleeve 19 is provided with a fixed baffle 15, and the outer dimension of the fixed baffle 15 is much larger than that of the support sleeve 19; a fixed hole penetrating left and right is provided in the middle of the fixed baffle 15, and a guiding rod 16 sleeved in the support sleeve 19 is fixedly installed in the fixed hole. The other end of the guiding rod 16 is fixedly installed at the corresponding position of the front column 4; a sliding retaining ring 18 is sleeved outside the support sleeve 19.
