Description

A low-voltage large-section single-core cable bending device and use method thereof

Technical Field

The invention relates to the technical field of bending equipment, and in particular to a low-voltage large-section single-core cable bending device and a use method thereof.

Background Art

Low-voltage large-section single-core cable refers to a single-core cable with a larger conductor cross-sectional area used in low-voltage power distribution systems. This type of cable is designed mainly for transmitting power at lower voltage levels (usually referring to the rated power frequency voltage of 0.6/1kV and below). At the same time, due to its larger conductor cross-sectional area (such as 240mm², adjustable diameter unit (300) mm², power unit (400) mm², etc.), it can carry a higher current load and is suitable for long-distance power transmission or occasions with high requirements for current capacity.

When laying cables, they often encounter special locations such as narrow spaces, pipe bends, and corners of cable trays. Cables generally need to be bent at these locations. The commonly used cable bending method is to use two push columns to push against one side of the cable, and then use the top column between the two push columns to squeeze the other side of the cable to bend the cable. When this bending method is used, the bent cable will form a certain angle, that is, the cable bending position cannot form an arc, and the arc at the cable bending position is small, which can easily cause cable stress concentration or cause cable core breakage due to excessive deformation in the local bending area, affecting the normal use of the cable.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

As shown in FIGS. 1 to 4 , a low-voltage large-section single-core cable bending device of the present invention comprises a base 100, a bending unit 200, a diameter adjustment unit 300 and a power unit 400, wherein the base 100 is used to provide support for the bending unit 200, the diameter adjustment unit 300 and the power unit 400;

The bending unit 200 is composed of a plurality of single plates 201 arranged side by side, and two adjacent single plates 201 are rotatably connected by a hinge shaft 202, the hinge shaft 202 is located in the middle of the side wall of the single plate 201, the side wall of the single plate 201 located on one side of the hinge shaft 202 is set as a cone surface 204, and the side wall of the single plate 201 located on the other side of the hinge shaft 202 is set as a loading platform 205. When two adjacent single plates 201 abut against each other through the plane 203, the plurality of single plates 201 are arranged in a straight line, and when two adjacent single plates 201 abut against each other through the cone surface 204, the plurality of single plates 201 are arranged in an arc shape. A loading platform 205 is slidably provided on the single plate 201, and a clamping unit for clamping a cable is provided on the loading platform 205. When the loading platform 205 moves on the single plate 201, the bending radius of the cable is adjusted;

Among them, the position of one single board 201 at one end of the multiple single boards 201 is fixed, and the power unit 400 is used to push the remaining multiple single boards 201 to move. When the number of movements of the remaining multiple single boards 201 changes, the bending curvature of the cable is adjusted, and the diameter adjustment unit 300 is used to adjust the position of the stage 205 on the single board 201.

In detail, the bending unit 200 serves as the main body of the bending cable, which can adjust the bending curvature and bending radius of the cable. Multiple single plates 201 are arranged side by side. The hinge shaft 202 on the single plate 201 is used to connect two adjacent single plates 201 and enable them to rotate relatively. The plane 203 can position the multiple single plates 201 in a straight line arrangement. The conical surface 204 can position the multiple single plates 201 in an arc arrangement, so that the multiple single plates 201 can switch between a straight line arrangement and an arc arrangement. When the multiple single plates 201 are arranged in a straight line, the cable can be placed on the clamping unit on the multiple single plates 201. When the single boards 201 are deformed into an arc-shaped arrangement, the cable is bent into an arc shape. Since the position of the first single board 201 among the multiple single boards 201 is fixed and the remaining multiple single boards 201 can move, the specific number of movements of the multiple single boards 201 can determine the arc of the cable bending, that is, the cable bending angle, and the number of movements of the multiple single boards 201 is calculated starting from the first single board 201, and the position of the stage 205 on the single board 201 can determine the distance between the clamping unit and the center of the circle where the multiple single boards 201 arranged in an arc shape are located, that is, the bending radius of the cable, thereby realizing the adjustment of the specific situation of the cable bending.

In actual use, the cable drum wrapped with the cable moves while releasing the cable. The cable drum can be moved by means of a vehicle or the like. The released cable no longer moves. When the cable drum moves to the position where the cable needs to be bent, the cable is placed on the clamping units on the multiple single boards 201. The power unit 400 is used to push the multiple single boards 201 to move and deform, so as to bend the cable. In order to facilitate the movement of the bending device, conventional structures such as legs and rollers can be installed at the bottom of the base 100.

Due to the large cross-sectional area and heavy weight of the cable, the released cable should not be moved again and can only be subjected to static bending. The traditional method of using the cable to perform arc rolling between three rollers distributed in a triangle is difficult and should not be used.

Through the innovative design of the bending unit 200, especially the rotatable and straight/arc arrangement switching functions of the single plate 201, and the adjustable position design of the stage 205 on the single plate 201, precise adjustment of the cable bending radius and bending curvature is achieved, which helps to avoid stress concentration and cell damage caused by excessive bending or inappropriate bending shape of the cable, and improves the safety and reliability of cable use; the device can flexibly adjust the bending degree of the cable according to actual needs, whether a smaller bending angle or a larger bending radius is required, it can be achieved by adjusting the number of single plates 201 and the position of the stage 205, which is suitable for cable laying needs in different installation environments, especially in small spaces or complex layouts that require turning at specific angles; the device has a simple structure, a simple cable deformation method, and reduces the difficulty of operation; in summary, the invention not only improves the accuracy and efficiency of cable bending operations, but also significantly enhances the safe use and maintenance convenience of cables. It is an important technical innovation for the difficult problem of laying low-voltage large-section single-core cables.

As shown in FIGS. 4 and 5 , guide plates 206 are provided on both the front and rear sides of the stage 205. One end of the guide plate 206 is horizontally slidably mounted on the side wall of the stage 205. The other end of the guide plate 206 vertically passes through the single board 201 and slides relatively. The guide plate 206 and the single board 201 are connected by a spring sheet 207.

The single board 201 has a slide groove, a latching tooth is arranged in the slide groove, the loading platform 205 is slidably installed in the slide groove, a latching tooth is arranged on the loading platform 205, and the latching tooth in the slide groove meshes with the latching tooth on the loading platform 205.

In detail, by setting the latch teeth to make the single board 201 and the loading platform 205 snap-fitted and connected, the position of the loading platform 205 on the single board 201 can be automatically locked to prevent the loading platform 205 from moving on the single board 201 when the cable is bent. The elastic downward pulling force of the spring sheet 207 and the guide plate 206 on the loading platform 205 can make the loading platform 205 firmly stuck on the single board 201. When the position of the loading platform 205 on the single board 201 needs to be adjusted, it is only necessary to lift the loading platform. 205, so that the stage 205 and the single board 201 are disengaged, and then the stage 205 can be slid in the slide groove. At this time, the stage 205 and the guide plate 206 slide relatively, and the guide plate 206 always provides a downward elastic pulling force for the stage 205. When the adjustment is completed, the stage 205 is released, and the spring piece 207 can pull the stage 205 to be stuck on the single board 201 again. This structural method realizes the locking function and can meet the needs of position adjustment of the stage 205.

As shown in Figure 6, the clamping unit includes two right-angle seats 208 arranged opposite to each other on the stage 205, each right-angle seat 208 is provided with a vertically slidable right-angle frame 209, the right-angle seat 208 and the right-angle frame 209 are connected by an elastic plate 210, and a plurality of cylindrical rubber bags 211 are rotatably provided on the elastic plate 210.

In detail, the rubber bag 211 can be filled with air or liquid, and the elastic plate 210 can be elastically deformed. In the natural state, the elastic plate 210 pushes the right-angle frame 209 and the right-angle seat 208 to form an opening with a maximum distance.

One right-angle seat 208 is fixed on the stage 205, and the other right-angle seat 208 can move on the stage 205. When the cable needs to be clamped, the cable is placed between the two right-angle seats 208, and the right-angle seat 208 that can move on the stage 205 is pushed to move. The two right-angle seats 208 are close to each other, and the multiple rubber bags 211 on the right-angle seats 208 squeeze and fix the outer wall of the cable. At the same time, due to the reverse squeezing of the cable, the elastic plate 210 is deformed in an arc shape, so that the multiple rubber bags 211 on it are 11 can contact with the cable, thereby increasing the force-bearing area of the cable. Due to the deformation of the elastic plate 210, the right-angle frame 209 slides on the right-angle seat 208, and the rubber bag 211 is reversely squeezed by the cable. There is a large contact area between the rubber bag 211 and the cable, thereby enabling the rubber bag 211 to play a buffering and protective role for the cable. At the same time, when the cable is bent, due to the deformation of the cable, relative movement will occur between it and the clamping unit. At this time, the cable will drive the rubber bag 211 to rotate on the elastic plate 210, so that the cable can be bent smoothly.

As shown in FIGS. 6 and 7 , the clamping unit further includes a sleeve 212 and an insertion rod 213. The sleeve 212 is fixed on one right-angle seat 208. The insertion rod 213 passes through another right-angle seat 208 and rotates relatively. A wrench 214 is provided at one end of the insertion rod 213. The other end of the insertion rod 213 is slidably inserted into the sleeve 212.

Among them, convex teeth 215 are provided on the inner wall of the sleeve 212 and the outer wall of the insertion rod 213, and a recessed area 216 is also provided on the outer wall of the insertion rod 213. When the insertion rod 213 rotates and the convex teeth 215 on it engage with the convex teeth 215 in the sleeve 212, the position between the sleeve 212 and the insertion rod 213 is locked. At this time, the wrench 214 is tilted and overlapped on the worktable 205. When the insertion rod 213 rotates and the recessed area 216 is toward the position of the convex teeth 215 in the sleeve 212, the sleeve 212 and the insertion rod 213 can slide relative to each other.

In detail, the two right-angle seats 208 are connected by a sleeve 212 and an insertion rod 213. When the insertion rod 213 is rotated by the wrench 214, the convex teeth 215 on the insertion rod 213 are rotated and clamped into the convex teeth 215 in the sleeve 212, the sleeve 212 and the insertion rod 213 are in a clamping state. At this time, the sleeve 212 and the insertion rod 213 cannot move relative to each other, and the position of the two right-angle seats 208 is locked. The wrench 214 is tilted and overlapped on the worktable 205. With the help of the wrench 214's own gravity, the insertion rod 213 cannot rotate at will, thereby maintaining the locked state of the two right-angle seats 208.

When the position between the two right-angle seats 208 needs to be adjusted, the wrench 214 is moved upward to rotate the insertion rod 213. At this time, the recessed area 216 moves to the convex tooth 215 area in the sleeve 212. The recessed area 216 and the convex tooth 215 in the sleeve 212 are in a separated state, thereby allowing the insertion rod 213 to slide in the sleeve 212, thereby facilitating the adjustment of the position relationship between the two right-angle seats 208.

As shown in FIG. 4 and FIG. 8 , two adjacent single plates 201 are connected via a leaf spring 217 ;

Each of the single plates 201 is provided with a through slot 218, and a card slot is provided on the inner wall of the through slot 218;

It also includes a slider 220, which slides in the through slots 218 on the multiple single plates 201. The slider 220 is provided with a clamping edge used in conjunction with the clamping slot. The slider 220 is obliquely provided with an inclined rod 219, and the power unit 400 provides thrust for the inclined rod 219.

In detail, each single board 201 is provided with a through groove 218 and a card slot, and the slider 220 can slide between multiple through grooves 218, so that the slider 220 is configured on different single boards 201. When the single board 201 needs to be pushed to move, the power unit 400 provides a force to the inclined rod 219 and pushes the inclined rod 219 to move, and the inclined rod 219 pushes the slider 220 to move. The card edges on the slider 220 move toward the card slot direction on the corresponding single board 201 and engage with each other. At this time, with the help of the thrust of the power unit 400, the single board 201 is moved, and the single board 201 drives the remaining multiple single boards 201 to move, thereby realizing the deformation movement of multiple single boards 201.

When the slider 220 needs to act on different boards 201 , it is only necessary to separate the edge on the slider 220 from the slot on the corresponding board 201 , so that the slider 220 can be switched between different through slots 218 , thereby adjusting the bending angle of the cable.

The leaf spring 217 can provide elastic tension between two adjacent single boards 201 , so that the plurality of single boards 201 can be arranged in a straight line in a natural state, and the two adjacent single boards 201 can be attached to each other through the plane 203 .

When the slider 220 is on different single boards 201, the multiple single boards 201 facing the first single board 201 of the slider 220 are the working area, and the single boards 201 in the working area can bend the cable, while the multiple single boards 201 facing the tail end of the single board 201 of the slider 220 are the idle area, and the multiple single boards 201 in the idle area will not bend or deform due to the action of the leaf spring 217.

The telescopic rod 222 passes through the rotating disk 223 and the base 100 .

In detail, the first single board 201 among the multiple single boards 201 is fixed on the base 100 by using a supporting plate 221, and each remaining single board 201 is installed on the base 100 by a telescopic rod 222 and a turntable 223. The position of the first single board 201 is fixed, and the remaining multiple single boards 201 can be moved by using the telescopic rod 222 and the turntable 223, so as to lift the multiple single boards 201. When the multiple single boards 201 are deformed, the single board 201 on the telescopic rod 222 can pull the telescopic rod 222 to extend, and the telescopic rod 222 tilts synchronously. At this time, the telescopic rod 222 drives the turntable 223 to rotate on the base 100.

In detail, since the adjustment work of the worktable 205 requires that it can move vertically and horizontally, when the ends of the Z-plate 303 are inserted into the multiple slots on the worktable 205, the cylinder 302 can be used to push the Z-plate 303 to move vertically, thereby moving the worktable 205 vertically, and the first motor 304, the gear column 305 and the tooth area on the Z-plate 303 can be used to push the Z-plate 303 to move horizontally, thereby moving the worktable 205 horizontally.

When the plurality of single boards 201 are deformed, the single boards 201 in the moving state can be directly separated from the Z-shaped board 303 , that is, the stage 205 is separated from the Z-shaped board 303 , thereby not affecting the movement of the single boards 201 .
