[0034] See also Figure 1 , Figure 3 , Fig.10 and Fig.11 , Figure 1 A schematic diagram of a cable laying device provided in one embodiment of the present invention is shown. Figure 3 Shows Figure 1 A partial cross-sectional view showing the cable laying device mounted on a bracket; Fig.10A schematic diagram showing the installation of the cable laying device provided in the second embodiment, the third embodiment and the fourth embodiment of the present invention on a bracket for cable laying; Fig.11 Shows Fig.10 A partial enlarged view of A shown. A cable laying device provided by an embodiment of the present invention comprises a mounting frame 100, a first roller 200 and a first drum 300. The mounting frame 100 is provided with a first mounting cavity 150 with an opening facing downward, the first mounting cavity 150 is used to accommodate the cross arm 710 of the bracket 700, and a mounting protrusion 121 is convexly provided on the side of the mounting frame 100 facing the first mounting cavity 150, and the mounting protrusion 121 is used to be inserted into the mounting groove 7111 of the cross arm 710; the first roller 200 is connected to the side of the mounting frame 100 away from the first mounting cavity 150; the first drum 300 is sleeved on the first roller 200 and can rotate around the axis of the first roller 200, and the outer surface of the first drum 300 is used to overlap the cable 800.

[0035] When the cable 800 is laid by the cable laying device, the cross arm 710 of the bracket 700 is first placed in the first installation cavity 150 of the mounting frame 100, and the mounting frame 100 can press the bottom wall of the first installation cavity 150 against the upper surface of the first support plate 711 of the cross arm 710 by its own gravity. Then the installation protrusion 121 on the mounting frame 100 is inserted into the installation groove 7111 of the cross arm 710, and the connection between the mounting frame 100 and the bracket 700 is completed. Then the cable 800 is overlapped on the outer surface of the first roller 300. The installer drags the cable 800 toward the laying direction, and the first roller 300 rotates relative to the first roller 200, so that rolling friction is formed between the cable 800 and the first roller 300, and the friction between the cable 800 and the first roller 300 is small, so the damage to the cable 800 is also small, the service life of the cable 800 is extended, and the use process is safer and less prone to leakage danger. At the same time, since the friction between the cable 800 and the first roller 300 is small, the pulling force of the installer to drag the cable 800 during the laying process of the cable 800 is also small, and a large amount of manpower is not required, and the laying speed is fast. After all the cables 800 are laid, the cable laying device is detached from the bracket 700 and stored for easy use in the next laying. Since the cable laying device can be reused many times and does not require a large amount of manpower, the installation cost required for the laying process of the cable 800 is greatly reduced. Moreover, after the cable laying device is detached and stored, the cable 800 is fixedly connected to the cross arm 710. Since the cable 800 is directly fixedly connected to the plate-shaped cross arm 710, the fixing of the cable 800 is also easier and more reliable.

[0036] In one specific embodiment, the mounting frame 100 is provided with two mounting arms 170 arranged opposite to each other, the two mounting arms 170 are respectively provided with mounting holes, the two ends of the first roller 200 are respectively connected to the two mounting holes, the first roller 200 is sleeved with two bearings, and the outer rings of the two bearings are sleeved with the first roller 300, so that when the first roller 300 rotates relative to the first roller 200, the friction between the two is smaller. When the first roller 300 is severely worn after long-term use, the first roller 200 can also be detached from the mounting hole to replace the first roller 300.

[0037] In one specific embodiment, the first roller 300 is a high-strength PVC pulley, which is not only low in cost but also light in weight, thereby making the entire cable laying device smaller in weight and easier for installers to handle and carry. Each installer can carry multiple cable laying devices at the same time.

[0038] The following is a detailed description of the structure of the cable laying device. Figure 2 and Figure 4-Figure 9 , Figure 2 Shows Figure 1 A schematic diagram of the installation of the mounting frame and the second roller of the cable laying device shown; Figure 4 Shows Figure 3 A cross-sectional view of a limiting assembly of a cable laying device shown; Figure 5 A schematic diagram of a cable laying device provided by a second embodiment of the present invention is shown; Figure 6 A schematic diagram of a cable laying device provided in a third embodiment of the present invention is shown; Figure 7 A schematic diagram of a cable laying device provided in a fourth embodiment of the present invention is shown; Figure 8 A schematic diagram of a cable laying device provided in a fifth embodiment of the present invention is shown; Fig. 9 Shows Figure 8 A cross-sectional view of the second drum in the cable laying device is shown.

[0039] See also Figure 1-Figure 3 and Figure 5-Figure 8 In one embodiment, the mounting frame 100 includes a first mounting plate 110, a second mounting plate 120, and a third mounting plate 130 connected in sequence. The first mounting plate 110 and the third mounting plate 120 are arranged opposite to each other, and the first mounting plate 110 and the third mounting plate 130 are arranged at an angle to the second mounting plate 120 to form a first mounting cavity 150. The second mounting plate 120 is pressed against the upper surface of the first support plate 711 of the cross arm 710 on the side facing the first mounting cavity 150. Since the first mounting cavity 150 is formed by three mounting plates, when the first support plate 711 is accommodated in the first mounting cavity 150, the cross arm 710 is not easy to move along the first mounting cavity 150. Figure 3In the event that the first mounting plate 110 and the third mounting plate 130 move in the left-right direction and detach from the first mounting cavity 150, the reliability of the installation of the cross arm 710 and the bracket 700 is relatively high. In one specific embodiment, the first mounting plate 110 and the third mounting plate 130 are both arranged at right angles to the second mounting plate 120, so that the first support plate 711 is easier to install and has a better anti-detachment effect. Of course, in other embodiments, the first mounting plate 110 and the third mounting plate 130 can also be arranged at an acute angle or an obtuse angle to the second mounting plate 120, and this is not limited. The first mounting plate 110, the second mounting plate 120 and the third mounting plate 130 can be connected by welding, or they can be integrally formed by casting.

[0040] See also Figure 3 The installation protrusion 121 of the cable laying device provided in one embodiment of the present invention is constructed on the second installation plate 120. The first support plate 711 is constructed with an installation groove 7111 that is plugged and matched with the installation protrusion 121. Since the installation protrusion 121 is constructed on the second installation plate 120, when the cross arm 710 is accommodated in the first installation cavity 150, the installation protrusion 121 can be more conveniently located and inserted into the installation groove 7111 under its own gravity. Through the cooperation between the installation protrusion 121 and the installation groove 7111, the second installation plate 120 is not easily relative to the first support plate 711 along the Figure 3 The first support plate 711 can move in the left and right directions, and the connection between the first support plate 711 and the mounting bracket 100 is more stable.

[0041] Please continue reading Figure 1-Figure 3 and Figure 5-Figure 8 , the cable laying device provided in one embodiment of the present invention also includes a fourth mounting plate 140, which is connected to the third mounting plate 130, and the fourth mounting plate 140 extends obliquely upward toward the first roller 300. The cable laying device also includes a limiting assembly 400, which is connected to the fourth mounting plate 140; the limiting assembly 400 includes a moving part 410, which passes through the fourth mounting plate 140 and can move along the thickness direction of the fourth mounting plate 140, and the moving part 410 can extend into the first mounting cavity 150 and form a snap-in groove with the fourth mounting plate 140, and the second support plate 712 of the cross arm 710 can be snapped into the snap-in groove on the side away from the first support plate 711. During the installation process of the mounting frame 100 relative to the bracket 700, since the mounting frame 100 and the bracket 700 are detachably connected, the mounting protrusion 121 and the mounting groove 7111 are clearance-matched, and the mounting frame 100 can be moved along Figure 3At this time, the moving member 410 is moved so that the moving member 410 moves along the thickness direction of the fourth mounting plate 140 and extends into the first mounting cavity 150 to form a snap-in groove with the fourth mounting plate 140, and the side of the second support plate 712 away from the first support plate 711 can be snapped into the snap-in groove, and the moving member 410 abuts against the end of the second support plate 712 close to the first mounting cavity 150 and applies abutting force, thereby preventing the entire mounting frame 100 from moving along the thickness direction of the fourth mounting plate 140 and extending into the first mounting cavity 150 to form a snap-in groove with the fourth mounting plate 140. Figure 3 The connection between the cross arm 710 and the mounting frame 100 is more stable.

[0042] See also Figure 4 The limiting assembly 400 of the cable laying device provided in one embodiment of the present invention further includes a fixing frame 420 and an elastic member 430. The fixing frame 420 is fixedly connected to the fourth mounting plate 140, and the fixing frame 420 is provided with a second mounting cavity 421, and the elastic member 430 is accommodated in the second mounting cavity 421, and the moving member 410 passes through the bottom wall of the second mounting cavity 421; the moving member 410 is provided with a limiting protrusion 411 protruding along its radial direction, and the elastic member 430 is sleeved on the moving member 410, and the elastic member 430 abuts between the limiting protrusion 411 and the bottom wall of the second mounting cavity 421. The limiting assembly 400 further includes a limiting member 440, and the limiting member 440 is connected to the side of the moving member 410 away from the second mounting cavity 421, and the width of the limiting member 440 is greater than the width of the moving member 410. When the mounting frame 100 needs to be mounted on the bracket 700, the installer pulls the stopper 440 along the side away from the second mounting cavity 421, so that the movable member 410 can move away from the second mounting cavity 421 under the drive of the stopper 440, and the elastic member 430 is in a compressed state under the movement of the stopper protrusion 411. At this time, the stopper assembly 400 no longer extends into the first mounting cavity 150, and the cross arm 710 can be conveniently accommodated in the first mounting cavity 150. When the cross arm 710 is accommodated in the first mounting cavity 150, the position of the mounting frame 100 is adjusted so that the mounting protrusion 121 is inserted into the mounting groove 7111. The installer stops pulling the stopper 440, and the movable member 410 moves closer to the second mounting cavity 421 under the elastic force of the elastic member 430, so that the movable member 410 extends into the first mounting cavity 150 to form a clamping groove with the fourth mounting plate 140, and the whole installation process is relatively simple to operate. Since the width of the stopper 440 is greater than the width of the moving member 410, when the moving member 410 moves closer to the second mounting cavity 421 under the elastic force of the elastic member 430, the moving member 410 will not be separated from the fourth mounting plate 140. In one specific embodiment, the elastic member 430 is a compression spring, and of course in other embodiments, the elastic member 430 can also be a bellows. In one specific embodiment, the stopper 440 is a ring member, which is convenient for the installer to pull.

[0043] See also Figure 1 and Figure 7 The cable laying device provided in one embodiment of the present invention further includes a second roller 500 and a second drum 600. The second roller 500 is connected to the mounting frame 100, and the second roller 500 is set at an angle to the first roller 200; the second drum 600 is sleeved on the second roller 500 and can rotate around the axis of the second roller 500, and the outer surface of the second drum 600 can abut against the cable 800. When the cable 800 overlaps the outer surface of the first drum 300 and slides, during the turning process, the cable 800 abuts against the outer surface of the second drum 600, and the second drum 600 rotates relative to the second roller 500, so that rolling friction is formed between the side wall of the cable 800 and the second drum 600, and the turning process can be smoother. Specifically, two bearings are sleeved and installed on the second roller 500, and the outer surfaces of the two bearings are sleeved and installed with the second drum 600, so that when the second drum 600 rotates relative to the second roller 500, the friction between the two is smaller. Please refer to Figure 2 In one embodiment, the second roller 500 is threadedly connected to the inner ring of the bearing, so that the disassembly and replacement of the second roller 600 is more convenient.

[0044] In one specific embodiment, the second roller 600 is a high-strength PVC pulley, which is not only low in cost but also light in weight, thereby making the entire cable laying device smaller in weight and easier for installers to handle and carry. Each installer can carry multiple cable laying devices at the same time.

[0045] See also Figure 1 and Figure 8 The number of the second rollers 500 of the cable laying device provided in one embodiment of the present invention is two, and the two second rollers 500 are respectively arranged at both ends of the first roller 200, and the number of the second rollers 600 is adapted to the number of the second rollers 500. Since two second rollers 500 and two second rollers 600 are arranged, the turning process of the cable 800 is relatively smooth during the laying process, whether it needs to turn left or right.

[0046] See also Figure 8 and Fig. 9The second roller 600 of the cable laying device provided in the fifth embodiment of the present invention includes a third step roller 610 and a fourth step roller 620, the fourth step roller 620 is connected to the side of the third step roller 610 away from the mounting frame 100, and the diameter of the fourth step roller 620 is greater than the diameter of the third step roller 610. Since the second roller 600 is set to be stepped, the fourth step roller 620 can prevent the cable 800 from moving up during the movement of the cable 800 turning left and right, so that the arrangement of the laid cables 800 is more neat and beautiful. In one of the specific embodiments, a transition fillet 611 is provided between the third step roller 610 and the fourth step roller 620, so that when the side wall of the cable 800 contacts the third step roller 610 and the fourth step roller 620 and rolls relative to each other during the laying process, the entire rolling process is smoother, and it is not easy to get stuck or scratch the insulation layer of the cable 800.

[0047] See also Figure 5-Figure 7 and Figure 10-11 The first roller 300 of the cable laying device provided in some embodiments of the present invention includes a first step roller 310 and a second step roller 320. The second step roller 320 is connected to the end of the first step roller 310, and the diameter of the second step roller 320 is larger than the diameter of the first step roller 310. When the cable 800 is being laid, when the installer drags the cable 800 in the laying direction, the cable 800 is not easy to slide along the axial direction of the first roller 300, and the entire laying process is relatively stable.

[0048] See also Figure 5 The first roller 300 of the cable laying device provided in the second embodiment of the present invention includes two second step rollers 320, and the two second step rollers 320 are respectively connected to the two ends of the first step roller 310, so that when the cable 800 is laid flat along its length, it is not easy to slide down along the two ends of the axial direction of the first roller 300.

This cable laying device is suitable for laying the cable 800. The cable 800 is arranged along the Figure 6 The axis of the first step roller turns right, and when the cable 800 turns right, the right side wall of the cable 800 abuts against the second roller 600, and the turning process is relatively smooth.

[0051] See also Figure 1-Figure 3 and Figure 5-Figure 8 The installation frame 100 of the cable laying device provided in one embodiment of the present invention is provided with a weight-reducing hole 160. By providing the weight-reducing hole 160, the weight of the installation frame 100 can be reduced, so that during the laying process, each installer can carry multiple cable laying devices at the same time, which is convenient to carry and reduces the labor intensity of the installer.

[0052] The present invention also provides a cable laying method, which is based on the above-mentioned cable laying device. When laying the cable 800, in one embodiment, the laying method includes the following steps: multiple cable laying devices are installed on multiple brackets 700; the cable 800 is overlapped on the outer surface of the first roller 200, and the cable 800 is dragged so that the cable 800 moves relative to the outer surface of the first roller 200 to the outer surface of the next first roller 200 along the laying direction; when the cable 800 is installed on all the brackets 700, the cable 800 is stopped from being dragged, and the cable laying device is detached; finally, the cable 800 is fixed on the bracket 700. Through this cable laying method, the cable laying device can be reused many times, which greatly reduces the installation cost required for the cable 800 laying process.

[0053] In another embodiment, when it is necessary to install multiple cable laying devices on multiple brackets 700, the above-mentioned cable laying method also includes: accommodating the cross arm 710 of the bracket 700 in the first installation cavity 150 of the mounting frame 100; pulling the limiting member 440 in the direction away from the side of the second installation cavity 421, so that the movable member 410 moves away from the second installation cavity 421; inserting the mounting protrusion 121 on the mounting frame 100 into the mounting groove 7111 on the first support plate 711 of the cross arm 710; loosening the limiting member 440, and the movable member 410 moves closer to the second installation cavity 421, and the movable member 410 extends into the second installation cavity 421 and forms a snap-in groove with the fourth mounting plate 140, and the second support plate 712 of the cross arm 710 is snap-into the snap-in groove on the side away from the first support plate 711. When the mounting frame 100 needs to be mounted on the cross arm 710 on the bracket 700, the installer pulls the stopper 440 in the direction away from the second mounting cavity 421, and inserts the mounting protrusion 121 on the mounting frame 100 into the mounting groove 7111 on the cross arm 710, so that the cable laying device can be installed on the bracket 700, which is very simple and convenient. When it is necessary to detach, the installer pulls the stopper 440 again, and separates the mounting protrusion 121 from the mounting groove 7111.
