[0033] Embodiment 1

[0034] Reference Figures 1-2 A cable deployment device comprises:

[0035] A base 10;

[0036] A support, which is rotationally connected with the base 10 and the rotation axis is in a vertical state;

[0037] A plurality of columns 30, which are circumferentially arranged on the support, and the axis of the column 30 is parallel to the axis of the support;

[0038] A plurality of beams 40, which are equidistantly arranged on a single column 30, and the beams 40 at the same height on all columns 30 form a support table.

[0039] By using the cable deployment device of the embodiment, the plurality of columns 30 form a mounting column around a circle, and the mounting column and the plurality of support tables together form a containing space for containing the electric flying wire. When the electric flying wire is deployed, one end of the electric flying wire is arranged and fixed at the top area of the mounting column, and the rotation of the support makes the electric flying wire be layered and wound between different support tables. For example, in the space between the top end of the mounting column and the first support table, the first closely wound layer is formed, which is wound from top to bottom and from inside to outside. Then, the electric flying wire is pulled to the space between the next adjacent support table to form the second wound layer. In this way, the process is repeated until the other end of the electric flying wire is arranged and fixed at the bottommost support table. At this time, the two oil injection holes of the electric flying wire are naturally distributed at the highest and lowest positions of the cable deployment device. The upper oil injection hole is convenient for connecting the vacuum pumping device, and the lower oil injection hole is convenient for connecting the oil injection pump, without the need to bend the electric flying wire.

[0040] It should be noted that the arrangement of the support tables starts from the uppermost support table, and from top to bottom, they are the first support table,..., and the nth support table.

[0041] In this embodiment, the bracket may include a mounting plate 210, a support column 220, a fixing ring 230, and multiple connecting rods 240. The multiple connecting rods 240 are circumferentially arranged on the support column 220, with one end of each connecting rod 240 away from the support column 220 connected to the fixing ring 230. The mounting plate 210 is fixed to the upper end of the support column 220. Both ends of the column 30 are connected to the mounting plate 210 and the connecting rods 240, respectively, and the connecting rods 240 support the column 30.

[0042] A large rotary bearing, which is a planar bearing, can be installed between the connecting rod 240 and the base 10 to allow the connecting rod 240 and the retaining ring 230 to rotate relative to the base 10.

[0043] The beams 40 corresponding to adjacent columns 30 are arranged in an alternating pattern, with a relatively large distance between two adjacent beams 40 on the same column 30. Specifically, for example:

[0044] Option 1: If the beams 40 of each layer are set to the same height, there are 16 columns 30, and 4 beams 40 are set on each column 30. If the beams 40 of adjacent columns 30 are arranged at the same height, the beams 40 of the same height form a support platform. This support platform is used to support the coil layer with a height of 2h, which is equivalent to 16 beams 40 supporting the coil layer with a height of 2h at the same time.

[0045] In this design, each support platform needs to bear the cumulative weight of all the coil layers above it. The bottom support platform bears the greatest force. At this time, the crossbeam 40 located below will bear a large concentrated shear force and bending moment at its connection with the column 30.

[0046] Option 2: If the crossbeams 40 of adjacent columns 30 are arranged in an alternating manner, then the crossbeams 40 of the same height form a support platform, which is used to support the coil layer of height h. This is equivalent to 8 crossbeams 40 supporting the coil layer of height h at the same time.

[0047] In this design, the span between beams 40 of the same height is relatively large. The electric wires will be suspended in the area with large span. The suspension areas of the electric wires in adjacent coil layers are different, thereby avoiding interlayer pressure and making the shear force and bending moment borne by the lower beam 40 relatively small.

[0048] In summary, the staggered arrangement of the crossbeams 40 can prevent the lower crossbeams 40 from being damaged due to excessive stress, thus extending their service life.

[0049] In this embodiment, the lower end of the base 10 may be provided with multiple casters 11 with self-locking function for easy handling.

[0050] Example 2

[0051] refer toFigures 1-6 The structure of the embodiment is substantially the same as that of Embodiment 1, except that the cable deployment device further comprises a limiting assembly and a plurality of rollers; a plurality of rollers are sleeved on each cross beam 40, and the rollers are rotatably connected with the cross beam 40; the limiting assembly is detachably connected with the cross beam 40, and the limiting assembly is used to limit the rollers from disengaging from the cross beam 40.

[0052] When the electric flying wire is wound on the mounting column, it will slide on the cross beam 40, causing the surface of the electric flying wire to be easily abraded. By arranging the rollers on the cross beam 40, the sliding friction of the electric flying wire on the cross beam 40 is changed into rolling friction, reducing the abrasion of the surface of the electric flying wire and making the movement of the electric flying wire more smooth and labor-saving.

[0053] When the rollers are installed, the rollers are sleeved on the cross beam 40, and then the limiting assembly is connected with the cross beam 40, so that the limiting assembly can avoid the rollers from disengaging from the cross beam 40 when the rollers rotate relative to the cross beam 40.

[0054] The roller comprises a wheel body 610, a rolling bearing 620 and a shaft sleeve 630; the shaft sleeve 630 is used to be sleeved on the cross beam 40, the shaft ends of the plurality of shaft sleeves 630 abut against each other, and the outermost shaft sleeve 630 is abutted against by the limiting assembly; the shaft length of the shaft sleeve 630 is greater than the shaft length of the wheel body 610; the inner ring of the rolling bearing 620 is fixedly sleeved on the shaft sleeve 630; and the wheel body 610 is fixedly sleeved on the outer ring of the rolling bearing 620.

[0055] The adjacent shaft sleeves 630 abut against each other, in the radial direction, the innermost shaft sleeve 630 abuts against the column 30, and the outermost shaft sleeve 630 abuts against the limiting assembly, the shaft sleeves 630 are mutually restrained, and when the wheel body 610 rotates relative to the cross beam 40, the shaft sleeves 630 are stationary relative to the cross beam 40.

[0056] The rolling bearing 620 makes the rotation of the wheel body 610 relative to the shaft sleeve 630 more smooth. The inner ring of the rolling bearing 620 can be connected with the shaft sleeve 630 by adhesion or interference fit, and the outer ring of the rolling bearing 620 can be connected with the wheel body 610 by adhesion or interference fit.

[0057] The shaft length of the shaft sleeve 630 is greater than the shaft length of the wheel body 610, and when the shaft sleeves 630 abut against each other, the adjacent wheel bodies 610 do not contact.

[0058] In this embodiment, the wheel body 610 can be composed of an installation layer, a reinforcing layer and an elastic layer from inside to outside, the installation layer is matched with the rolling bearing 620, and the installation layer can be made of stainless steel material; the reinforcing layer is the main body for bearing, i.e. for bearing the pressure of the electric flying wire, so the reinforcing layer can be made of steel material, such as 45# steel; and the elastic layer is used to directly contact the electric flying wire, and when the surface of the electric flying wire has pits or protrusions, the elastic layer can play a buffering role to avoid the electric flying wire from shaking during movement.

[0059] The limiting assembly includes a limiting rod 510, a plug-in locking mechanism, and a connecting unit; the connecting unit is detachably connected to the cross beam 40, and the cross-sectional area of ​​the connecting unit is larger than that of the cross beam 40; one end of the limiting rod 510 is provided with a plug-in unit, which cooperates with the plug-in locking mechanism to realize the quick connection and disassembly of the limiting rod 510 and the plug-in locking mechanism.

[0060] The cross-sectional area of ​​the connecting unit is greater than that of the cross-section of the beam 40, that is, the cross-sectional area of ​​the connecting unit is greater than the inner diameter of the bushing 630. The connecting unit can prevent the bushing 630 from detaching from the beam 40.

[0061] If the distance between two adjacent crossbeams 40 in the axial direction is d, in this embodiment, the length of the limiting rod 510 can be greater than d. Before winding the electric wire, the limiting rod 510 is removed from the insertion and locking mechanism. After one layer of electric wire is wound, the limiting rod 510 is connected to the insertion and locking mechanism. At this time, the axis of the limiting rod 510 is parallel to the axis of the column 30, and the limiting column can prevent the wound electric wire from coming off.

[0062] The plug-in unit and plug-in locking mechanism can be quickly connected and disassembled, making the installation of the limit rod 510 relatively convenient.

[0063] The connecting unit includes a cover 531 and a mounting base 532; the mounting base 532 is detachably connected to the crossbeam 40 and is provided with a plug-in locking mechanism; the cover 531 is detachably connected to the mounting base 532 and is provided with a receiving cavity for fitting the mounting base 532 and a first plug-in hole 5311 for the limit rod 510 to pass through; the outer diameter of the cover 531 is larger than the outer diameter of the crossbeam 40.

[0064] The mounting base 532 can have the same diameter as the crossbeam 40, and the cover 531 can be fitted onto the outside of the mounting base 532. In this case, the cover 531 can prevent the roller from detaching from the crossbeam 40. The cover 531 and the mounting base 532 are detachably connected. When it is necessary to install the roller, the cover 531 can be removed from the mounting base 532 in advance so that the roller can be fitted onto the outside of the crossbeam 40 from the mounting base 532, and then the cover 531 can be connected to the mounting base 532.

[0065] The cover 531 has a first mounting hole, and the mounting base 532 has a first threaded hole 5321 corresponding to the first mounting hole. A bolt passes through the first mounting hole and engages with the first threaded hole 5321, thus completing the connection between the cover 531 and the mounting base 532. The number of first mounting holes can be four. To avoid confusion, the bolt connecting the cover 531 and the mounting base 532 is referred to as the first bolt 533. The positions of the first bolt 533 and the first threaded hole 5321 are as follows: Figure 3 and Figure 4 As shown.

[0066] In the embodiment, the mounting seat 532 is provided with a second mounting hole 5322, which is arranged at the bottom of the second plug hole 5323, and the cross beam 40 is provided with a second threaded hole 41 corresponding to the second mounting hole 5322. The bolt is inserted into the second mounting hole 5322 and matched with the second threaded hole 41, so that the mounting seat 532 is connected with the cross beam 40. The bolt connecting the mounting seat 532 and the cross beam 40 is called the second bolt 534, and the positions of the second bolt 534 and the second threaded hole 41 are as shown in Figure 3

[0067] It should be noted that the second mounting hole 5322 is a stepped hole, and the second mounting hole 5322 can accommodate the nut of the bolt to prevent the bolt from interfering with the movement of the limiting rod 510 in the second plug hole 5323.

[0068] The plug-in unit includes a first clamping block 511, a second clamping block 512 and a top rod 513. The projection of the first clamping block 511 on the axis of the cross beam 40 is an isosceles trapezoid A71, the first clamping block 511 is connected with the top rod 513 and the lower base of the isosceles trapezoid A71 is close to the top rod 513, the top rod 513 is connected with the limiting rod 510, and the width of the top rod 513 is less than the width of the limiting rod 510.

[0069] The second clamping block 512 is slidingly arranged on the top rod 513, and the projection of the second clamping block 512 on the axis of the cross beam 40 is an isosceles trapezoid B72, and the lower base of the isosceles trapezoid B72 is close to the lower base of the isosceles trapezoid A71.

[0070] The plug-in locking mechanism includes a third clamping block 521 and a first elastic member 522. The mounting seat 532 is provided with a second plug hole 5323 matched with the limiting rod 510 and a mounting groove 5324 communicated with the second plug hole 5323. The third clamping block 521 is slidingly arranged in the mounting groove 5324, and the projection of the third clamping block 521 on the axis of the cross beam 40 is a right trapezoid C73, and the hypotenuse of the right trapezoid C73 faces the side of the limiting rod 510. The two ends of the first elastic member 522 are connected with the mounting seat 532 and the third clamping block 521 respectively.

[0071] The number of plug-in locking mechanisms can be two and symmetrically distributed on both sides of the axis of the limiting rod 510.

[0072] ​In the initial state, a part of the third clamping block 521 extends into the second plug hole 5323 under the action of the first elastic member 522; when the limiting rod 510 is just inserted into the second plug hole 5323, the first clamping block 511 and the second clamping block 512 are located on the same side of the third clamping block 521, and with the continuous deepening of the limiting rod 510 in the second plug hole 5323, the first clamping block 511 moves to the installation groove 5324, at this time, the waist of the isosceles trapezoid A71 first contacts the acute angle of the right trapezoid C73, the first clamping block 511 presses the third clamping block 521 into the installation groove 5324, and the first elastic member 522 is compressed; with the continuous deepening of the limiting rod 510, the first clamping block 511 is disengaged from the installation groove 5324, and the third clamping block 521 reenters the second plug hole 5323 under the action of the first elastic member 522, at this time, the third clamping block 521 is located between the first clamping block 511 and the second clamping block 512, the second clamping block 512 slides relative to the jack 513 under the abutting action of the third clamping block 521, the second clamping block 512 abuts against the limiting rod 510, and at this time, the axial movement of the limiting rod 510 is limited; when the limiting rod 510 continues to move axially, the limiting rod 510 drives the second clamping block 512 to move in the second plug hole 5323, the acute angle of the isosceles trapezoid B72 presses the inclined surface of the right trapezoid C73, the third clamping block 521 is pressed into the installation groove 5324 again, and until the long side of the isosceles trapezoid B72 passes through the installation groove 5324, the third clamping block 521 moves to the second plug hole 5323 under the action of the first elastic member 522 and is always in contact with the second clamping block 512, that is, the acute angle of the right trapezoid C73 is always abutted against the inclined side of the isosceles trapezoid B72; at this time, the limiting rod 510 is axially separated, the limiting rod 510 drives the second clamping block 512 to move through the first clamping block 511, the inclined surface of the second clamping block 512 presses the third clamping block 521 to slide in the installation groove 5324 and compresses the first elastic member 522, when the third clamping block 521 completely enters the installation groove 5324, the first clamping block 511 can move away from the installation groove 5324, at this time, the third clamping block 521 no longer limits the movement of the first clamping block 511.

[0073] When the limiting rod 510 is separated from the second plug hole 5323, the lower base of the isosceles trapezoid B72 and the isosceles trapezoid A71 almost move at the same time, when the lower base of the isosceles trapezoid B72 moves to the side wall of the installation groove 5324 and is flush with it, the third clamping block 521 just completely enters the installation groove 5324, the length of the lower base L1 of the isosceles trapezoid B72 is greater than the length of the lower base L2 of the isosceles trapezoid A71, and when the first elastic member 522 drives the third clamping block 521 to move a distance of (L2-L1) / 2, the limiting rod 510 has driven the first clamping block 511 to move a certain distance through the jack 513, at this time, the acute angle of the third clamping block 521 can only contact the inclined surface of the first clamping block 511, so that the third clamping block 521 cannot be inserted between the first clamping block 511 and the second clamping block 512, and thus the third clamping block 521 no longer limits the movement of the limiting rod 510.

[0074] The first elastic member 522 comprises a first spring, two ends of the first spring are connected with the third clamping block 521 and the mounting seat 532 respectively.

[0075] The side wall of the mounting groove 5324 is provided with a limiting protrusion 5325, and the third clamping block 521 is provided with a limiting groove matched with the limiting protrusion 5325, so that the third clamping block 521 is prevented from being separated from the mounting groove 5324 under the action of the first elastic member 522.

[0076] The limiting assembly further comprises a second elastic member, one end of the second elastic member is connected with the cover body 531, and the other end of the second elastic member is a free end and is used for abutting against the first clamping block 511.
