DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, a cable laying device includes: a cable drum 110, a vertical rod group, a horizontal rod group and a support frame group.

[0027] A cable 130 is wound around the circumferential side of the cable drum 110, wherein the cable 130 can be an optical cable or an electrical cable. The cable 130 is wound around the outer circumferential side of the cable drum 110 layer by layer and circle by circle, and the cable 130 can be pulled out in sequence when it is unwound later. A cable drum shaft 120 is set at the axial position of the cable drum 110, and the outer circumferential side of the cable drum shaft 120 is fixedly connected to the inner circumferential side of the cable drum 110; it should be noted that after the cable drum 110 is placed on the platform, the top surface of the cable drum 110 is kept horizontal as much as possible, and the cable drum shaft 120 and the horizontal plane are as perpendicular to each other as possible.

[0028] A vertical rod group is inserted into the wire drum shaft 120, and the lower end of the vertical rod group is rotationally connected to the wire drum shaft 120. Further, the inner peripheral side surface of the wire drum shaft 120 is rotationally connected to the outer peripheral side surface of the lower end of the vertical rod group, thereby ensuring that the vertical rod group can rotate freely relative to the wire drum 110.

[0029] The vertical rod group is connected to the transverse rod group, and the right end of the transverse rod group is detachably connected to the vertical rod group. A wire loosener 330 is set at the left end of the transverse rod group. The wire loosener 330 is used to pass the cable 130 and assist in pulling the cable 130 for unwinding. According to the height of the cable drum 110, the height position of the transverse rod group on the vertical rod group is adjusted to ensure that the wire loosener 330 can normally guide the cable 130 to unwind.

[0030] A support frame group is set at the upper end of the vertical rod group, and a guide wheel 470 is set on the top surface of the support frame group. The setting of the guide wheel 470 is used to assist in adjusting the pulling direction of the cable 130. Preferably, the support frame group is installed directly above the wire drum shaft 120, that is, the guide wheel 470 is located at the axial position of the wire drum shaft 120. When the cable 130 is pulled, the force point of the guide wheel 470 is located as directly above the wire drum 110 as possible, thereby improving the stability of the unwinding device when the cable 130 is unwound.

[0031] Of course, the position of the support frame group can also be set according to the situation. Under the condition that the unwinding device is sufficiently stable when the cable 130 is unwound, the support frame group can deviate from the axis of the reel shaft 120 by a certain distance, and it does not have to be installed at the axis position of the reel shaft 120.

[0032] During operation, the cable drum 110 is placed on the platform, the vertical rod group is inserted into the cable drum shaft 120, the transverse rod group is connected to the vertical rod group, one end of the transverse rod group is connected to the wire loosening device 330, one end of the cable 130 passes through the wire loosening device 330, and reaches the guide wheel 470 through the support frame group; the end of the cable 130 is pulled, and the cable 130 drives the guide wheel 470 to rotate a certain angle in the horizontal direction, and simultaneously drives the wire loosening device 330 to rotate with the cable drum shaft 120 as the axis, unwinding the cable 130, according to the direction of travel of the cable 130, until the cable 130 is pulled to the designated location. It is no longer necessary to suspend the cable drum 110 through auxiliary equipment, which reduces the preconditions for cable release, reduces the labor intensity and construction difficulty, improves the construction flexibility of the entire cable release device, and avoids the safety hazards such as overturning and falling of the cable drum 110. In addition, the cable 130 has almost no inertia when unwinding, and the cable release speed can be accurately controlled, thereby improving the efficiency of manual cable release.

[0033] In one embodiment of the utility model, the vertical rod group includes: a vertical outer sleeve 210 inserted into the wire drum shaft 120, the lower end of the vertical outer sleeve 210 is rotatably connected to the inner peripheral side of the wire drum shaft 120, and the upper part of the vertical outer sleeve 210 is inserted into a vertical inner sleeve 220. The vertical inner sleeve 220 and the vertical outer sleeve 210 will not rotate relative to each other. The vertical inner sleeve 220 is connected to the vertical outer sleeve 210 through a plurality of first fastening bolts 250. When the first fastening bolt 250 is screwed in the forward direction, the first fastening bolt 250 no longer locks the relative position of the vertical inner sleeve 220 in the vertical outer inner sleeve, and the vertical inner sleeve 220 can slide freely in the vertical outer sleeve 210 to flexibly adjust the length of the vertical rod group. When the first fastening bolt 250 is screwed in the reverse direction, the first fastening bolt 250 locks the relative position of the vertical inner sleeve 220 in the vertical outer inner sleeve, thereby completing the length adjustment of the vertical rod group.

[0034] like Figure 2As shown, in the second embodiment of the utility model, the vertical rod group includes: a first vertical outer sleeve 230 inserted into the wire drum shaft 120, the lower end of the vertical outer sleeve 210 is rotatably connected to the inner circumferential side of the wire drum shaft 120, the upper end of the first vertical outer sleeve 230 is inserted into the vertical inner sleeve 220, and the upper end of the vertical inner sleeve 220 is inserted into the lower end of the second vertical outer sleeve 240, that is, the upper and lower ends of the vertical inner sleeve 220 are respectively socket-connected to the upper end of the first vertical outer sleeve 230 and the lower end of the second vertical outer sleeve 240, and at the same time, the first vertical outer sleeve 230 and the second vertical outer sleeve 240 are connected to the vertical inner sleeve 220 by a plurality of first fastening bolts 250. The adjustment method of the vertical rod group is the same as the above method, except that the vertical rod group can be suitable for higher wire drums 110.

[0035] The transverse rod group includes: a transverse outer sleeve 310 arranged on the vertical inner sleeve 220, the transverse outer sleeve 310 and the vertical inner sleeve 220 are arranged crosswise, that is, there is a certain angle between the transverse outer sleeve 310 and the vertical inner sleeve 220. It should be noted that when the vertical rod group adopts the second embodiment, the transverse outer sleeve 310 and the second vertical outer sleeve 240 are arranged crosswise, the right end of the transverse outer sleeve 310 is inserted into the transverse inner sleeve 320, and the transverse inner sleeve 320 is connected to the transverse outer sleeve 310 through a plurality of second fastening bolts 340. According to the maximum outer diameter of the cable drum 110, the length of the left end of the transverse inner sleeve 320 extending out of the transverse outer sleeve 310 is adjusted, and then the position of the wire loosening device 330 is adjusted so that the wire loosening device 330 extends out of the circumferential outer side of the cable drum 110, ensuring that the wire loosening device 330 can guide the cable 130 normally.

[0036] Preferably, the transverse outer sleeve 310 and the vertical inner sleeve 220 are arranged perpendicular to each other. On the one hand, when the cable 130 is released, the vertical inner sleeve 220 is stably stressed, thereby improving the overall stability of the cable release device. On the other hand, the transverse outer sleeve 310 is perpendicular to the vertical inner sleeve 220. When the transverse inner sleeve 320 is moved in the transverse outer sleeve 310, the position of the wire loosening device 330 can be directly adjusted horizontally without changing the horizontal plane where the wire loosening device 330 is located, making the adjustment of the wire loosening device 330 more convenient and accurate. Further, a vertical sleeve is integrally arranged on the circumferential side of the transverse outer sleeve 310. The vertical sleeve and the transverse outer sleeve 310 are perpendicular to each other, and the vertical sleeve is directly connected to the outer circumferential side of the vertical inner sleeve 220 by clamping, thereby fixing the transverse outer sleeve 310.

[0037] It should be noted that when placing the cable drum 110, the top surface of the platform is made as close to a horizontal state as possible, ensuring that the axial direction of the cable drum 110 is perpendicular to the horizontal plane, that is, the axis of the cable drum 110 is in a vertical state as much as possible, and the axial direction of the cable drum 110 is perpendicular to the transverse rod group, and the transverse rod group is in a horizontal state. When the cable 130 is released, it is further ensured that the wire releaser 330, the transverse rod group and the vertical rod group are stably stressed, thereby improving the overall stability of the cable release device.

[0038] Of course, under the premise of ensuring that the wire loosener 330 is above the wire drum 110 and can normally extend outwardly from the circumference of the wire drum 110, the angle between the horizontal outer sleeve 310 and the vertical inner sleeve 220 can be freely selected according to the situation.

[0039] An annular conductive coil 331 is provided at the left end of the cable loosener 330. The annular conductive coil 331 is circular in shape as a whole. Furthermore, the annular conductive coil 331 extends out of the cable drum 110 to ensure that the annular conductive coil 331 can normally guide the cable 130. Preferably, the annular conductive coil 331 is completely closed, and the end of the cable 130 is passed through the annular conductive coil 331. When the cable 130 is unwound, the cable 130 is not easy to fall off from the annular conductive coil 331.

[0040] Of course, the annular conductive coil 331 can also be set to a semi-closed state, that is, a certain gap is left in the annular conductive coil 331, and the gap is set at a position that does not contact the annular conductive coil 331 when the cable 130 is unwound. When the cable reel 110 is repaired and the cable 130 does not need to be unwound, the cable 130 can be removed and put in through the gap, which is more convenient to use.

[0041] A connecting rod 332 is provided at the right end of the wire loosener 330, and the connecting rod 332 is inserted into the left end of the transverse inner sleeve 320, and the plug rod can rotate a certain angle relative to the transverse inner sleeve 320. The acute angle between the axial direction of the annular conductor coil 331 and the top surface of the cable drum 110 is between 30° and 60°. When the cable 130 is unwound, the annular conductor coil 331 rotates relative to the transverse inner sleeve 320 as the height position of the cable 130 on the cable drum 110, and flexibly adjusts its own state. At this time, when the cable 130 passes through the annular conductor coil 331 for unwinding, the bending degree of the cable 130 is minimized, and the friction resistance of the annular conductor coil 331 to the cable 130 is reduced as much as possible, and the unwinding process of the cable 130 is smoother.

[0042] like Figure 3As shown, the support frame group includes: a lower tray 410, the lower tray 410 is arranged at the upper end of the vertical rod group, the top surface of the lower tray 410 is provided with a support member with an open side, a flexible protective cover is provided on the outer side of the lower tray 410, and a flexible protective cover is provided on the open part of the support member. Preferably, the flexible protective cover is made of rubber material, which can effectively prevent the support member and the lower tray from directly contacting the cable to cause wear on the outer sheath of the cable, thereby improving the service life of the cable. Of course, the flexible protective cover can also be made of other flexible materials such as silicone.

[0043] Preferably, the support member uses four support rods 420, the outer peripheral side of the support rods 420 is covered with a rubber protective sleeve, the four support rods 420 are perpendicular to the top surface of the lower tray 410, the upper ends of the four support rods 420 are connected to the upper tray 430, and the four support rods 420 are perpendicular to the bottom surface of the upper tray 430, wherein the cable 130 passes between two adjacent support rods 420 to reach the guide wheel 470.

[0044] A rotating bearing 510 is arranged on the top surface of the upper tray 430. Preferably, the lower end of the rotating bearing 510 is fixed to the top surface of the upper tray 430 by welding, and the upper end of the rotating bearing 510 is connected to the rotating sleeve 520. The rotating sleeve 520 and the rotating bearing 510 are arranged coaxially, and the upper end of the rotating sleeve 520 is connected to the support plate 440. A mounting frame 450 is arranged on the top surface of the support plate 440. The mounting frame 450 is rotatably connected to the guide wheel 470 through the support shaft 460. The guide wheel 470 can rotate freely around the support shaft 460. As one end of the cable 130 is pulled, the guide wheel 470 automatically adjusts its own state, thereby driving the rotating sleeve 520 to rotate a certain angle, so that the cable 130 can be pulled in a direction perpendicular to the axis of the guide wheel 470, thereby ensuring that the smoothness of the unwinding of the cable 130 is improved, and the unwinding efficiency of the cable 130 is improved.

[0045] In addition, a first through hole (not shown in the figure) is provided on the top surface of the upper tray 430, and a second through hole (not shown in the figure) is provided on the top surface of the support plate 440. The first through hole, the second through hole and the rotating sleeve 520 are coaxially arranged. The cable 130 passes through the first through hole, the rotating sleeve 520 and the second through hole to reach the guide wheel 470. The rotating sleeve 520 can adjust the rotation direction of the guide wheel 470 on the one hand, and on the other hand, can guide and correct the cable 130 to a nearly vertical state, ensuring that the cable 130 is not easy to slide off the outer peripheral side of the guide wheel 470 when passing through the guide wheel 470, further improving the stability of the cable 130 when unwinding.

[0046] When the utility model is used, the wire drum 110 is placed on the platform, the lower end of the vertical outer sleeve 210 is inserted into the wire drum shaft 120, the vertical inner sleeve 220 is inserted into the vertical outer sleeve 210, and the vertical inner sleeve 220 is fixed relative to the vertical outer sleeve 210 by the first fastening bolt 250, the transverse outer sleeve 310 is fixed on the vertical inner sleeve 220, the transverse inner sleeve 320 is inserted into the transverse outer sleeve 310, and the transverse inner sleeve 320 is fixed relative to the transverse outer sleeve 310 by the second fastening bolt 340. At this time, after the left end of the horizontal inner sleeve 320 is connected to the wire releaser 330, the annular wire coil 331 extends out of the outer peripheral side of the cable drum 110, and the cable 130 passes through the annular wire coil 331, passes through the rotating sleeve 520 to reach the guide wheel 470, and pulls the end of the cable 130. The cable 130 drives the rotating sleeve 520 to rotate a certain angle through the guide wheel 470, and simultaneously drives the wire releaser 330 to rotate around the cable drum shaft 120 as the axis, unwinding the cable 130, and according to the travel direction of the cable 130, the cable 130 is pulled to the designated location.

[0047] In summary, the utility model drives the wire loosener 330 to rotate around the wire drum shaft 120 through the cable 130 to unwind the cable 130, replacing the traditional wire drum 110 to rotate and unwind the cable 130. There is no need to suspend the wire drum 110 through auxiliary equipment, which reduces the labor intensity and construction difficulty of manual labor, improves the construction flexibility of the entire cable unwinding device, and avoids the safety risks of overturning and falling of the wire drum 110. Moreover, there is no need to overcome the rotational inertia force of the wire drum 110. The rotational resistance of the cable 130 is small when unwinding, and the cable has almost no inertia when unwinding. The cable unwinding speed can be accurately controlled, thereby improving the efficiency of manual cable unwinding.

[0048] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
