Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of communication engineering cable construction equipment, and particularly relates to a cable installation device for communication engineering construction. BACKGROUND

[0002] The communication engineering cable installation device covers the whole process equipment of "laying, termination and testing", and the cable laying traction machine is the core equipment for long-distance laying of cables (optical cables and electric cables) in communication and power engineering, and mainly solves the problems of low manual traction efficiency and uneven tension.

[0003] In the scenarios of direct-buried trench laying, temporary ground laying and unprotected pipeline inlet section, the cable has its own weight and naturally contacts the ground. When traction is performed, the relative movement of the cable and the ground directly generates friction. At this time, the stones and sharp debris on the ground are easy to scratch the sheath, resulting in a decrease in the insulation of the cable (electric cable) or moisture in the optical fiber (optical cable). In addition, the friction resistance in the friction process increases the traction load, which may exceed the tension threshold of the traction machine, and even cause the cable to stretch and deform. In addition, the friction jam slows down the traction speed and needs to be frequently stopped for cleaning obstacles. When the ground has protrusions and debris, the cable will hard contact with these obstacles, and the friction will be intensified.

[0004] In the prior art, a protective soft pad is usually laid at the contact part of the cable and the ground to protect the cable. However, when the cable is gradually laid into the trench or the pipeline, the surface of the cable is easy to be attached with some sand due to the influence of the construction environment. The sand is easy to fall on the surface of the protective soft pad. In addition, since the cable has its own weight, there is a obvious depression at the contact part of the protective soft pad and the cable. The depression is easy to gather sand, and thus the sand at the contact part of the cable and the protective soft pad is increased, which further intensifies the abrasion of the cable sheath during traction.

DETAILED DESCRIPTION

[0029] The following further describes the present application in conjunction with the drawings. It is necessary to point out here that the following detailed description is only used to further describe the present application and cannot be understood as limiting the protection scope of the present application. The skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0030] Embodiment 1 As Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 5 、 Figure 6 and Figure 7 As shown in FIGS. 1-5, a cable installation device for communication engineering construction includes a rack 1, a reduction motor 4 fixedly installed on the top of the rack 1, and a spoke reel 5 at the output shaft end of the reduction motor 4. The spoke reel 5 is rotatably installed on the top of the rack 1, and the reduction motor 4 is coaxially arranged with the rotation shaft of the spoke reel 5. A positioning mechanism 2 is fixedly installed on the side of the rack 1, and a protection mechanism 3 is movably installed at the end of the positioning mechanism 2 by bolts. The protection mechanism 3 is in an inclined state and overlaps the ground, groove, or pipeline inlet section to form a transition channel for cable traction. The protection mechanism 3 includes a plurality of protection frames connected in series to form a spine support positioning structure. Each protection frame includes two symmetrically arranged semicircular protection plates 31. After the two semicircular protection plates 31 are spliced, an accommodation chamber 39 is formed between the inner sides of the two semicircular protection plates 31. The accommodation chamber 39 is used to accommodate the cable, and the semicircular protection plates 31 are used to protect the cable. Two guide protrusions 313 are arranged at the bottom of the inner side wall of the semicircular protection plate 31 along the length direction of the semicircular protection plate 31. A support plate 314 is fixedly connected between the two guide protrusions 313. A second support wheel 315 is rotatably installed at the top of the guide protrusion 313. When the cable is being pulled, the cable overlaps the second support wheel 315.

[0031] In this embodiment, the implementation scenario is as follows. During construction, the rack 1 is fixed at the starting end of the cable traction area. According to the traction position, the protection mechanism 3 is installed on the positioning mechanism 2. Under the action of gravity, the protection mechanism 3 is in an inclined state and overlaps the ground, groove edge, or pipeline inlet to form a continuous transition channel from the spoke reel 5 to the laying destination. The cable is released or pulled from the spoke reel 5. The spoke reel 5 is provided with a traction rope. The device needs to be used in combination with a traction machine. The traction machine mainly includes a power mechanism and a traction mechanism. The traction mechanism includes a traction rope and a traction head. The traction head is installed at the end of the traction rope. The other end of the traction rope is connected to the winding device of the power mechanism. During use, the traction head is connected to the end of the cable, and then the cable is placed in the protection mechanism 3. The traction machine pulls the cable by winding the traction rope through the traction head. The spoke reel 5 uniformly rotates to release the cable. The cable is positioned through the support and guidance of the positioning mechanism 2. Finally, the excess part of the cable is wound on the traction machine. Then, the traction head is detached to release the cable. In this way, the ground laying, groove laying, or pipeline laying operation is completed.

[0032] It should be noted that the protection mechanism 3 is formed by a plurality of protection frames in series to form a flexible spine support positioning structure, and the adjacent two protection frames are connected in a splicing manner. The number of protection frames can be freely increased or decreased according to the length requirement of the actual traction path during use. The protection mechanism 3 can meet the needs of short-distance ground laying and pipeline entry section traction, and can be extended to a long-distance trench laying scene through multi-section splicing. The protection mechanism 3 does not need to be designed separately for different path lengths, greatly improves the universality of the device, reduces the construction equipment investment cost, and has a certain gap between adjacent protection frames. When the cable is being pulled, the adjacent two protection frames can rotate up and down relative to each other, which can flexibly adapt to the terrain undulation and corner change in the traction path, such as the slope of the trench edge and the bending angle of the pipeline entry, so that the protection mechanism 3 is always closely fitted with the traction path, avoiding the cable from leaving the protection range due to irregular path.

[0033] It should be further noted that each protection frame is composed of two symmetrically arranged half-round protection plates 31. The inner side of the two half-round protection plates 31 forms a closed containing chamber 39 after splicing, realizing all-around wrapping containing and protection of the cable, avoiding external sundries directly contacting the cable. This state is suitable for cables with small diameters. When the cable diameter is large, the two half-round protection plates 31 can form a half-enclosed protection structure to protect the cable. The inner side wall bottom of the half-round protection plate 31 is provided with two guide protrusions 313 along the length direction of the half-round protection plate 31, which plays a role in positioning the support plate 314. Two second support wheels 315 are arranged on the two support plates 314. During the process of pulling the cable, the two second support wheels 315 are symmetrically distributed on the two sides below the cable, which can play a guiding and limiting role during the process of pulling the cable, preventing the cable from shifting left and right during the traction process. The second support wheel 315 contacts the cable in a rolling manner, converting traditional sliding friction into rolling friction, which greatly reduces the traction resistance, prevents the cable sheath from being worn, and the presence of the support plate 314 and the guide protrusion 313 also plays a role in gathering sand. During the traction process, the sand on the surface of the cable naturally falls between the two guide protrusions 313 and flows out from the gap between the two protection frames along the guide protrusion 313, thereby avoiding wear of the cable sheath due to friction with the sand. The support plate 314 enhances the structural strength of the guide protrusion 313, avoiding deformation when bearing the weight of the cable and the traction pressure. The second support wheel 315 is rotatably installed on the top of the guide protrusion 313.

[0034] Embodiment 2 As Figure 4 , Figure 6 and Figure 7As shown, the bottom of the semicircular protective plate 31 is provided with a support portion 36 along the length direction of the semicircular protective plate 31, and the support portion 36 is parallel to the support plate 314. The support portion 36 is used to contact the ground. When the cable is overlapped on the second support wheel 315, a trapezoidal support structure is formed between the two support portions 36, the two anti-dropping balls 312 and the cable. An extension frame 37 is arranged on the outer wall of the semicircular protective plate 31. The extension frame 37 is located at the intersection of the semicircular protective plate 31 and the guide convex strip 313. A handle 38 is fixedly connected to the rod body of the extension frame 37. The handle 38 is located on the side of the support portion 36.

[0035] It should be noted that the support portion 36 is arranged in parallel with the support plate 314, directly contacts the ground, the groove wall or the edge of the pipeline inlet, and provides a support base point for the entire protective frame. According to the actual installation environment, the support portion 36 can be arranged in parallel with the support plate 314, or the support portion 36 can be arranged in parallel with the support plate 314 and the guide convex strip 313. Figure 7 As shown in FIG. 6, when the cable is overlapped on the second support wheel 315, an extension line is drawn from the tangent point of the cable and the second support wheel 315 and the center of the two support portions 36. The circular dashed line in the figure is the cable, and the straight dashed line is the extension line. As can be seen from the dashed line in the straight dashed line, the support portion 36 cooperates with the second support wheel 315 and the cable to form a trapezoidal support state. The trapezoidal structure has natural mechanical stability, can uniformly disperse the weight of the cable and the horizontal tension during traction to the support portion 36, avoids local stress concentration to cause deformation or displacement of the protective frame, effectively offsets the lateral force generated during traction, prevents the overall deviation of the protection mechanism 3, and ensures that the cable is always pulled along the preset path. During the traction process, the weight of the cable will continuously press down the second support wheel 315, thereby ensuring the stability of the two semicircular protective plates 31 by pressing down the second support wheel 315.

[0036] Moreover, the thickness of the support portion 36 allows the semicircular protective plate 31 to be separated from the contact surface by a certain distance, which can directly avoid the sand and water on the ground from entering the accommodating cavity 39, thereby reducing the risk of the second support wheel 315 being stuck by debris and further isolating the indirect scratching of the cable sheath by the sharp protrusions on the ground, thereby strengthening the protection effect.

[0037] It should be further noted that, as shown in FIGS. 1, 2 and 3, the semicircular protective plate 31 is provided with a plurality of anti-dropping balls 312 arranged on the outer wall of the semicircular protective plate 31. The anti-dropping balls 312 are arranged in pairs on the two sides of the semicircular protective plate 31, and the anti-dropping balls 312 are arranged in pairs on the two sides of the semicircular protective plate 31. Figure 7 Figure 10 As shown in FIGS. 1, 2 and 3, the extension frame 37 and the handle 38 arranged on the outer wall of the semicircular protective plate 31 are used for the operator to hold at any time and rotate the semicircular protective plate 31 to the two sides, thereby exposing the internal space, facilitating the deployment and removal of the cable. Moreover, during the deployment, the construction personnel can quickly carry and adjust the position of the single protective frame by holding the handle 38, and can also assist in aligning and splicing the interfaces when a plurality of frames are connected in series, thereby greatly improving the installation and disassembly efficiency.

[0038] ​When the support part 36 is in contact with the ground, due to its flat shape, the friction between the support part 36 and the contact surface is easy to drive the semicircular protection plate 31 during the traction of the cable, and the friction will be more intense under the action of the weight of the semicircular protection plate 31 and the cable. Therefore, another solution is provided in this embodiment, as shown in Figure 9 The surface of the support part 36 is provided with an arc-shaped recess 361, which is located at the middle section of the support part 36. The two ends of the support part 36 are provided with arc-shaped protruding parts 362, which form a wave-shaped limiting structure with the arc-shaped recess 361.

[0039] It should be noted that the protruding structure of the arc-shaped protruding part 362 can engage with the small recesses, gravel or groove edges of the ground, and the arc-shaped recess 361 can accommodate the protruding debris or sand of the ground, forming a clamping limiting to improve the stability of the protection frame on different terrains. Compared with the flat shape, the wave shape can have a good limiting effect. When the cable is pulled to generate a horizontal force, the wave-shaped structure can generate a transverse resistance through the concave-convex matching with the contact surface, preventing the support part 36 from sliding in the traction direction, which can effectively prevent the entire semicircular protection plate 31 from being pulled away from the preset position by the cable, and ensure that the protection frame always maintains a stable posture.

[0040] Embodiment 3 As shown in Figure 6 , Figure 7 and Figure 8 , one end of the support part 36 is integrally formed with a connecting rod 311, and the end of the connecting rod 311 is provided with a anti-dropping ball 312. The other end of the support part 36 is internally provided with a docking chamber 310, which is composed of a spherical cavity and a cylindrical cavity. The shape of the spherical cavity is matched with the anti-dropping ball 312, and the diameter of the cylindrical cavity is larger than that of the connecting rod 311. The anti-dropping ball 312 is inserted into the inside of the spherical cavity. One side of the support part 36 is fixedly installed with a positioning plate 316 through a bolt, and the end of the positioning plate 316 is provided with an anti-dropping plate 317 which is perpendicular to the positioning plate 316 and is inserted into the joint of the cylindrical cavity and the spherical cavity of the docking chamber 310. One side of the anti-dropping plate 317 is in contact with the edge of the anti-dropping ball 312, which is used to prevent the anti-dropping ball 312 from being separated from the docking chamber 310. The edge of the positioning plate 316 inside the docking chamber 310 is provided with a guide groove 318, which is located at the edge of the connecting rod 311 and provides an up-down swinging space for the connecting rod 311.

[0041] It needs to be explained that when the two protection frames are butted with the semicircular protection plate 31, the anti-disengagement ball 312 is inserted into the butt joint cavity 310, which adopts a combined structure of a spherical cavity and a columnar cavity, the spherical cavity is matched with the anti-disengagement ball 312, and the columnar cavity provides mounting and movement space for the connecting rod 311. After the anti-disengagement ball 312 enters the spherical cavity, the positioning plate 316 is installed on the side of the support part 36, the anti-disengagement plate 317 at the end of the positioning plate 316 is inserted into the intersection of the columnar cavity and the spherical cavity, forming a limiting structure for the anti-disengagement ball 312, thereby completing the quick connection of the adjacent protection frames, without the need for complex tools, and greatly improving the assembly efficiency of the multi-section frame.

[0042] It also needs to be explained that the guide groove 318 is arranged at the edge of the anti-disengagement plate 317, and in the initial state as shown in Figure 7 , the guide groove 318 not only provides a certain movement space for the connecting rod 311, but also retains the limiting effect on the anti-disengagement ball 312, and the angle of the guide groove 318 is close to the state perpendicular to the ground, so that the connecting rod 311 can swing in the vertical direction within a fixed range, thereby ensuring that the multi-section protection frame can adapt to different terrains.

[0043] Embodiment 4 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , one end of one of the semicircular protection plates 31 is rotatably connected with the connecting end 32 through the support part 36, the end of the connecting end 32 is rotatably connected with the first rotating rod 33, the first rotating rods 33 are symmetrically arranged, and the end of each first rotating rod 33 is rotatably connected with the second rotating rod 34, the end of the second rotating rod 34 is rotatably connected with the positioning end 35, the second rotating rod 34 rotates up and down around the positioning end 35 as the center, and the first rotating rod 33 swings up and down around the end of the second rotating rod 34, for adjusting the position of the connecting end 32.

[0044] It needs to be explained that the connecting end 32, the first rotating rod 33, the first rotating rod 33 and the second rotating rod 34, and the second rotating rod 34 and the positioning end 35 are all designed to be rotatably connected, forming a three-stage rotating joint structure similar to a mechanical arm, wherein the second rotating rod 34 can swing up and down around the positioning end 35 within a fixed range, and at the same time, the two second rotating rods 34 determine the specific direction of the entire protection mechanism 3, thereby ensuring that the traction direction is always aligned with the spoke type winding drum 5 at the top of the rack 1, the first rotating rod 33 can swing up and down around the end of the second rotating rod 34, for adapting to different heights of the terminal position, and the cooperation of the first rotating rod 33 and the second rotating rod 34 enables the connecting end 32 to adjust the position below the side of the spoke type winding drum 5, so as to adapt to the contact surface of different terrains.

[0045] Example 5 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the positioning mechanism 2 comprises a mounting connecting plate 21 located directly below the spoke reel 5, the bottom of the mounting connecting plate 21 is fixedly connected with an electric cylinder 23, the electric cylinder 23 is fixedly installed on the bottom of the rack 1, the four corners of the mounting connecting plate 21 are fixedly connected with guide columns 22, the bottom of the guide columns 22 is fixedly connected with the rack 1, the inside of the mounting connecting plate 21 is provided with two strip-shaped holes 27, the two strip-shaped holes 27 are located on the centerline of the mounting connecting plate 21 and are symmetrically distributed along the spoke reel 5, the inside of the strip-shaped hole 27 is slidably provided with a sliding block 24, the top of the sliding block 24 is rotatably installed with a first supporting wheel 25, the first supporting wheel 25 is used to support the cable, the lower surface of the mounting connecting plate 21 is rotatably installed with a driven rotary rod 26, the driven rotary rod 26 penetrates the connecting head of the piston rod end of the guide column 22, the surface of the driven rotary rod 26 is symmetrically provided with two opposite spiral grooves, and the driven rotary rod 26 is threadedly connected with the two strip-shaped holes 27, the lower surface of the mounting connecting plate 21 is rotatably installed with a control rod 210, the control rod 210 is perpendicular to the driven rotary rod 26, the end of the control rod 210 is fixedly installed with a second bevel gear 29, the outer wall of the middle segment of the driven rotary rod 26 is fixedly installed with a first bevel gear 28, and the first bevel gear 28 is engaged with the second bevel gear 29.

[0046] It should be noted that the extension and retraction of the piston rod of the electric cylinder 23 is used to adjust the height of the mounting connecting plate 21, and the height of the mounting connecting plate 21 and the first supporting wheel 25 on the upper surface thereof can be adjusted according to the inclination angle requirement of the protection mechanism 3 and the cable release height of the spoke reel 5, the positioning end 35 is installed at the corner of the end of the mounting connecting plate 21, the change of the height of the mounting connecting plate 21 can adjust the height of the end of the protection mechanism 3, so that the protection mechanism 3 can adapt to the height of different contact surfaces, and in the process of lifting the mounting connecting plate 21, the guide column 22 can determine the moving direction of the mounting connecting plate 21.

[0047] It also needs to be explained that the slider 24 is arranged in the strip-shaped hole 27 of the mounting connecting plate 21 and moves up and down along with the mounting connecting plate 21, so that the first supporting wheel 25 can adapt to the change of the height of the protection mechanism 3, and the first supporting wheel 25 is used for supporting the cable between the protection mechanism 3 and the spoke type winding drum 5, so that the cable can be smoothly transitioned, and the friction caused by the bending or height difference of the cable at the traction starting section is avoided. The two strip-shaped holes 27 are symmetrically distributed along the center line of the mounting connecting plate 21 and are aligned with the spoke type winding drum 5, so that the adjustment of the two first supporting wheels 25 is always carried out around the central axis of the cable traction, and in the traction process, as the number of cable turns on the spoke type winding drum 5 increases or decreases, the position of the cable between the protection mechanism 3 and the spoke type winding drum 5 also changes. At this time, the operating rod 210 is rotated, the second bevel gear 29 at the end of the operating rod 210 is engaged with the first bevel gear 28 on the driven rotating rod 26, and the opposite spiral grooves symmetrically arranged on the surface of the driven rotating rod 26 are used to drive the slider 24 to move along the strip-shaped hole 27, so as to adapt to the position of the cable. The mounting connecting plate 21 is located below the spoke type winding drum 5, so that the cable can vertically fall to the first supporting wheel 25 after being released from the winding drum, and the horizontal traction force loss is reduced. The vertical arrangement of the operating rod 210 and the driven rotating rod 26 enables the construction personnel to conveniently operate on the side of the mounting connecting plate 21, and the construction personnel will not be on the traction route, so that the safety of the operator is ensured.

[0048] The working principle of the application is as follows: The rack 1 is arranged at the starting end of construction, the spoke type winding drum 5 is driven by the speed reducer motor 4 to provide stable power for the cable winding and unwinding, and the positioning mechanism 2 is used for transition and connection during the winding and unwinding of the cable. The mounting connecting plate 21 is driven by the electric cylinder 23 to ascend and descend along the direction of the guide column 22, so as to adapt to the inclination angle of the protection mechanism 3 and the cable release height of the spoke type winding drum 5. By rotating the operating rod 210, the first bevel gear 28 and the second bevel gear 29 are engaged and driven, the driven rotating rod 26 is rotated, the slider 24 is slid along the strip-shaped hole 27, the position of the first supporting wheel 25 is adjusted, the cable is supported and guided, and the bending or height difference friction at the traction starting section is avoided. The positioning end 35 of the protection mechanism 3 is installed at the corner of the mounting connection plate 21. The whole is inclined and overlapped with the ground, trench or pipe entrance to form a continuous transition channel for the cable. During construction, the number of protection frames is determined according to the construction terrain. When splicing the protection frames, the anti-detachment ball 312 at the bottom of the semi-circular protection plate 31 in one protection frame is inserted into the docking chamber 310 in the bottom support part 36 of the semi-circular protection plate 31 in another protection frame. After the splicing is completed, the positioning plate 316 is installed on the side of the support part 36. The anti-detachment ball 312 is limited by the anti-detachment plate 317 at the end of the positioning plate 316. In actual use, the number of frames can be freely increased or decreased according to the length of the traction path. The existence of the guide groove 318 allows the relative rotation between two adjacent protection frames to adapt to the terrain undulations and corner changes. When the cable diameter is small, the two symmetrically arranged semicircular protective plates 31 are spliced ​​together to form a closed receiving chamber 39, which realizes all-round wrapping protection of the cable. When the cable diameter is large, the two symmetrically arranged semicircular protective plates 31 can be adjusted to a semi-enclosed protection structure to adapt to the protection requirements of large-diameter cables. The second support wheel 315 inside the receiving chamber 39 converts the sliding friction of cable traction into rolling friction, reducing resistance and sheath wear. During the traction process, the support plate 314 between the guide protrusions 313 enhances the structural strength and collects and discharges sand and soil from the cable surface. The support part 36 at the bottom of the semi-circular protective plate 31 contacts the ground. Its wave-shaped limiting structure engages with the ground through the arc-shaped protrusion 362 and the arc-shaped recess 361 accommodates the protruding contact surface, thereby improving the stability of the protective mechanism 3. The positioning end 35, the first rotating rod 33, the second rotating rod 34 and the connecting end 32 are sequentially rotated and connected, so that the connecting end 32 can be adjusted in position below the spoke drum 5 to adapt to the contact surface of different terrains. After determining the status of the entire device, connect one end of the cable to the traction head of the traction machine, and place it into the receiving chamber 39 of the protection mechanism 3. The cable is released at a constant speed by the spoke-type drum 5, supported by the rolling of the second support wheel 315, and guided by the first support wheel 25. Finally, the traction rope is wound onto the winding equipment of the traction machine to complete the ground deployment, trench laying, or pipe laying operations. The excess cable is also wound onto the traction machine.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
