Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to a cable laying device and a laying method. Background Art

[0002] Cable is a bundle of wires used to transmit electrical energy, data or signals. It is usually made of one or more insulated conductors wrapped in insulating materials. Cables are widely used in various fields, such as construction, communication and energy transmission. There are many types and uses of cables, including power cables, communication cables and fiber optic cables.

[0003] Cable laying refers to the installation of cables in buildings, cable wells, underground pipelines or on the ground to transmit power, data or signals. The cable well is a well used to accommodate and protect the cable connection points. The side walls of the cable well are provided with laying grooves. The cable passes through the laying groove of one side wall of the cable well and enters the laying groove of the adjacent side wall to change the laying direction of the cable.

[0004] For example, in the Chinese patent application document with publication number CN115588940A and titled Cable Laying Device, when it is necessary to lay cables in a power pipeline, the relevant staff first places the cable laying device in the power pipeline, and then places one end of the cable to be laid between multiple clamping mechanisms, and the staff controls the first adjustment mechanism to drive the clamping mechanism to expand and clamp one end of the cable. The staff controls the third adjustment mechanism to drive the walking mechanism to walk in the power pipeline, and the walking mechanism drives the cable to move in the power pipeline through the clamping mechanism, thereby laying the cable in the power pipeline.

[0005] With regard to the above-mentioned related technologies, due to the different angles of the side walls of the cable well, the angles of the cable turning angles are different, so different numbers and shapes of laying components are required to adjust the angles of the cables. This method requires the production of laying components of different specifications, which increases the cost of laying cables. In addition, during the specific construction phase, the staff needs to transport laying components of different specifications for cable wells of different shapes, which increases the workload of the staff, thereby adversely affecting the laying efficiency of the cables. Summary of the invention

[0006] In view of this, the present invention provides a cable laying device and a laying method, aiming to solve the problem that laying components of different specifications need to be produced, which increases the cost of laying cables and has an adverse effect on the laying efficiency of the cables.

[0007] To solve the above technical problems, in a first aspect, the present invention provides a cable laying device, including a cable laying device, including a cable well and a laying trough; a first support rod and a second support rod erected in the cable well, the first support rod and the second support rod are both fixedly connected with a connecting rod, a rotating pin is hinged between the two connecting rods, the connecting rod is threadedly connected with a transmission screw at one end away from the rotating pin, each connecting rod is provided with a limiting roller abutting against a cable body, and the transmission screw is threadedly connected with a support frame abutting against a side wall of the cable well at one end away from the connecting rod; the first support rod is hinged with the limiting rod, the second support rod is hinged with a first bracket, the limiting rod is internally threaded with a first adjusting screw, the first adjusting screw is rotatably connected to the first bracket, and the rotation of the first adjusting screw can adjust the angle between the two connecting rods with the rotating pin as the origin.

[0008] By adopting the above technical solution, the angle between the two connecting rods is adjusted by rotating the first adjusting screw, so that the connecting rods can adapt to the different angles between the inner walls of the cable well for instant adjustment, instead of producing laying components of corresponding specifications for cable wells of different specifications, thereby reducing the cost of laying cables, reducing the operating steps of the staff, and improving the efficiency of laying cables.

[0009] Optionally, the connecting rod is provided with a slide groove, the limiting roller is arranged in the slide groove, the limiting roller is fixedly connected with a transmission block, the transmission block is threadedly connected with a second adjusting screw, and the second adjusting screw is rotatably connected to the connecting rod.

[0010] By adopting the above technical solution, the limiting roller is moved along the slide groove to control the bending radius of the cable body, thereby reducing the probability of the cable body being damaged due to the bending radius being less than the minimum bending radius.

[0011] Optionally, the support frame includes a first transmission rod threadedly connected to the transmission screw, the first transmission rod is slidably connected to the second transmission rod, the first transmission rod is hinged with a locking rod, the locking rod is hinged with a rotating rod at one end away from the first transmission rod, the rotating rod is hinged to the second transmission rod at one end away from the first transmission rod, the first transmission rod is fixedly connected with a third handle that can abut against the top wall of the second transmission rod, and the second transmission rod is hinged with a third support rod at one end away from the first transmission rod that can abut against the side wall of the cable well.

[0012] By adopting the above technical solution, when removing the support frame from the side wall of the cable well, the third handle is turned upward, the locking rod rotates with the third handle, and the locking rod drives the rotating rod to rotate, thereby making the second transmission rod approach the first transmission rod and detach from the inner wall of the cable well, thereby realizing the rapid removal of the support frame from the inner wall of the cable well.

[0013] Optionally, the support frame is fixedly connected with a guide mechanism, and the guide mechanism is used to adjust the relative position between the cable body and the laying groove.

[0014] Optionally, the guiding mechanism comprises a supporting ring fixedly connected to the supporting frame, an outer side wall of the supporting ring is rotatably connected to a limiting ring, and the cable body passes between the limiting ring and the supporting ring.

[0015] By adopting the above technical solution, the support ring and the limit ring are respectively in contact with the side wall of the laying groove, thereby increasing the coaxiality of the cable body and the laying groove and reducing the probability of damage caused by contact and friction between the cable body and the side wall of the laying groove. When the cable body is laid, the limit ring is rotated so that the limit ring and the support ring overlap to form a semicircular ring, thereby facilitating the removal of the cable body from the guide mechanism.

[0016] Optionally, the connecting rod is fixedly connected to a fourth support rod at one end close to the rotating pin, a third adjusting screw is internally threadedly connected to the fourth support rod, an end of the third adjusting screw away from the fourth support rod is hinged to a friction plate abutting against the side wall of the cable well, and a second handle is fixedly connected to the side wall of the third adjusting screw.

[0017] Optionally, a fourth adjusting screw is threadedly connected inside the first support rod and the second support rod, and a support plate is hinged on the bottom wall of the fourth adjusting screw, and the support plate abuts against the bottom wall of the cable well.

[0018] By adopting the above technical solution, when the bottom wall of the cable well has an inclination angle, the support plate adapts to the top wall of the cable well and rotates to a corresponding angle, so that the first support rod and the second support rod can be erected in the cable well to support the cable body.

[0019] In a second aspect, the present invention provides a cable laying method, which is applied to a cable laying device described in the first aspect, and the laying method is:

[0020] S1, passing the cable body through the guide mechanism, and then laying the cable body into the laying grooves of the adjacent two side walls of the cable well, the cable body is bent and abuts against the side walls of the limiting roller, and the first adjusting screw is rotated to adjust the angle between the two connecting rods;

[0021] S2, rotating the transmission screw to adjust the distance between the support frame and the side wall of the cable well, so that the support frame abuts against the side wall of the cable well to support the cable body;

[0022] S3, rotating the third adjusting screw to adjust the distance between the friction plate and the side wall of the cable well, so that the support frame abuts against the side wall of the cable well to support the cable body.

[0023] By adopting the above technical solution, according to the angle between the two side walls of the cable well, the staff rotates the first adjustment screw to make the connecting rod and the side wall of the cable well perpendicular, so that the support frame can fit the side wall of the cable well to support the first support rod and the second support rod. The support frame and the friction plate support the cable body, which increases the stability of the cable body laying process.

[0024] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0025] 1. By rotating the first adjusting screw to adjust the angle between the two connecting rods, the connecting rods can adapt to the different angles between the inner walls of the cable well for instant adjustment, instead of producing laying components of corresponding specifications for cable wells of different specifications, the cost of laying cables is reduced, and the operating steps of the staff are reduced, thereby improving the efficiency of laying cables.

[0026] 2. When the cable body contacts the limit roller, the bending radius of the cable body is the radius of the circle tangent to the two connecting rods with the two limit rollers as the tangent point. When the angle between the two connecting rods decreases, the bending radius of the cable body will decrease accordingly, thereby moving the limit roller away from the rotating pin, thereby increasing the bending radius of the cable body and reducing the probability of damage to the cable body due to too small bending radius.

[0027] 3. After the cable body is laid, lift the third handle upwards. When the locking rod and the rotating rod overlap along the axial direction, the locking rod pulls the cable body into the cable well through the first transmission rod, the transmission screw, the connecting rod and the limit roller to deform the cable body. Continue to turn the third handle upwards, the locking rod rotates with the third handle, and the locking rod drives the rotating rod to rotate, so that the second transmission rod approaches the first transmission rod and separates from the inner wall of the cable well, thereby realizing the rapid removal of the support frame from the inner wall of the cable well.

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0037] In a first aspect, this embodiment provides a cable laying device, referring to Figure 1 , Figure 2 and Figure 3 A cable laying device includes a cable well 1 and a laying groove 11 opened on the side wall of the cable well 1. A first support rod 2 and a second support rod 3 are erected in the elevator well, and the first support rod 2 and the second support rod 3 are respectively fixedly connected to a connecting rod 4, and a rotating pin 41 is hinged between the two connecting rods 4. The end of each connecting rod 4 away from the rotating pin 41 is rotatably connected to a transmission screw 42, and the side wall of each transmission screw 42 is fixedly connected to a fourth handle 421. The end of each transmission screw 42 away from the connecting rod 4 is threadedly connected to a support frame 5 abutting against the side wall of the cable well 1, and each connecting rod 4 is provided with a limiting roller 43. The cable body 9 is bent in the laying groove 11 and laid in the laying groove 11 of the adjacent two side walls of the cable well 1, and the limiting roller 43 guides and supports the cable body 9.

[0038] Reference Figure 2 and Figure 3The first support rod 2 is hinged with a limit rod 21, the second support rod 3 is hinged with a first bracket 31, the limit rod 21 has a first adjusting screw 22 internally threadedly connected, the first adjusting screw 22 is rotatably connected to the first bracket 31 at one end away from the limit rod 21, and the side wall of the first adjusting screw 22 is fixedly connected with a first handle 221.

[0039] The staff rotates the first handle 221, and the first adjusting screw 22 rotates with the first handle 221 to adjust the distance between the first adjusting screw 22 and the limiting rod 21. The first support rod 2 moves with the limiting rod 21, and the second support rod 3 moves with the first adjusting screw 22 through the first bracket 31, thereby adjusting the distance between the first support rod 2 and the second support rod 3. The connecting rod 4 moves with the first support rod 2 and the second support rod 3 and rotates around the rotating pin 41, thereby the rotation of the first adjusting screw 22 can adjust the angle between the two connecting rods 4 with the rotating pin 41 as the origin.

[0040] According to the angle between the two side walls of the cable well 1, the staff rotates the first handle 221 around the first adjusting screw 22 for a corresponding number of turns, so that the angle between the two connecting rods 4 and the angle between the two side walls of the cable well 1 are complementary, so that the connecting rods 4 and the side walls of the cable well 1 are perpendicular. By rotating the fourth handle 421, the transmission screw 42 rotates with the fourth handle 421 to move the support frame 5, and adjust the distance between the support frame 5 and the side wall of the cable well 1, so that the support frame 5 can fit the side wall of the cable well 1 to support the first support rod 2 and the second support rod 3, and then support the cable body 9.

[0041] The cable body 9 passes through the laying groove 11 of one side wall of the cable well 1, and then is bent and passed into the laying groove 11 of the adjacent side wall of the cable well 1. The staff pulls the cable body 9 to the outside of the cable well 1, and the cable body 9 abuts against the side wall of the limiting roller 43 and is tightened.

[0042] By rotating the first adjusting screw 22 to adjust the angle between the two connecting rods 4, the connecting rods 4 can adapt to the different angles between the inner walls of the cable well 1 for instant adjustment, instead of producing laying components of corresponding specifications for cable wells 1 of different specifications, thereby reducing the cost of laying cables, reducing the operating steps of the staff, and improving the efficiency of laying cables.

[0043] Reference Figure 4The connecting rod 4 is provided with a slide groove 44 along the axial direction, and the limiting roller 43 is arranged in the slide groove 44. The limiting roller 43 can move along the axial direction of the slide groove 44, and the limiting roller 43 can rotate in the slide groove 44. The limiting roller 43 is fixedly connected with a transmission block 431, and the transmission block 431 is threadedly connected with a second adjusting screw 432. The second adjusting screw 432 is rotationally connected to the connecting rod 4, and one end of the second adjusting screw 432 is fixedly connected with a transmission nut 433. The second adjusting screw 432 and the transmission block 431 form a screw slider structure. When the staff uses a wrench to rotate the transmission nut 433, the second adjusting screw 432 rotates with the transmission nut 433, so that the transmission block 431 and the limiting roller 43 move synchronously along the axial direction of the slide groove 44.

[0044] Since the cable body 9 has a minimum bending radius, the minimum bending radius refers to the minimum bending radius allowed by the cable body 9 during use. When the cable body 9 abuts against the limiting roller 43, the bending radius of the cable body 9 is the radius of a circle tangent to the two connecting rods 4 with the two limiting rollers 43 as the tangent point. When the angle between the two connecting rods 4 decreases, the bending radius of the cable body 9 will decrease accordingly, thereby making the limiting roller 43 away from the rotating pin 41, thereby increasing the bending radius of the cable body 9 and reducing the probability of the cable body 9 being damaged due to the small bending radius.

[0045] Reference Figure 4 and Figure 5 The support frame 5 includes a first transmission rod 51 threadedly connected to the transmission screw 42, the first transmission rod 51 is slidably connected to the second transmission rod 52, the first transmission rod 51 is hinged with a locking rod 53, the locking rod 53 is hinged with a rotating rod 54 at one end away from the first transmission rod 51, the rotating rod 54 is hinged to the second transmission rod 52 at one end away from the first transmission rod 51, the first transmission rod 51 is fixedly connected with a third handle 55 that can abut against the top wall of the second transmission rod 52, and the second transmission rod 52 is hinged with a third support rod 56 that can abut against the side wall of the cable well 1 at one end away from the first transmission rod 51.

[0046] The transmission screw 42 rotates to adjust the distance between the third support rod 56 and the side wall of the cable well 1, so that the third support rod 56 abuts against the side wall of the cable well 1. When the cable body 9 is pulled to the outside of the cable well 1, the cable body 9 presses the third support rod 56 against the side wall of the cable well 1 through the limiting roller 43. At this time, the locking rod 53 and the rotating rod 54 are subjected to axial pressure, the bottom wall of the third handle 55 abuts against the top wall of the second transmission rod 52, the angle between the top wall of the locking rod 53 and the top wall of the rotating rod 54 is less than 180 degrees, and the locking rod 53 and the rotating rod 54 abut against the top wall of the second transmission rod 52, thereby limiting the rotation of the locking rod 53 and the rotating rod 54, so that the distance between the first transmission rod 51 and the second transmission rod 52 remains unchanged, so that the third support rod 56 supports the cable body 9.

[0047] After the cable body 9 is laid, the third handle 55 is lifted upward. Since the cable body 9 is a flexible part, the third handle 55 is rotated upward, so that the locking rod 53 and the rotating rod 54 overlap along the axial direction, and the locking rod 53 has a tendency to pull the cable body 9 into the cable well 1. The locking rod 53 pulls the cable body 9 into the cable well 1 through the first transmission rod 51, the transmission screw 42, the connecting rod 4 and the limiting roller 43, so that the cable body 9 is deformed. Continue to rotate the third handle 55 upward, and the locking rod 53 rotates counterclockwise with the third handle 55 (refer to Figure 5 ), the locking rod 53 drives the rotating rod 54 to rotate, thereby making the second transmission rod 52 close to the first transmission rod 51 and thus detaching from the inner wall of the cable well 1, thereby realizing the rapid removal of the support frame 5 from the inner wall of the cable well 1.

[0048] Reference Figure 5 and Figure 6 The support frame 5 is fixedly connected with a guide mechanism 6, and the guide mechanism 6 is used to adjust the position of the cable body 9 relative to the laying groove 11. The guide mechanism 6 includes a support ring 61 fixedly connected to the third support rod 56, and the outer wall of the support ring 61 is rotatably connected to the limit ring 62. The support ring 61 and the limit ring 62 are semicircular rings, and the side walls of the support ring 61 and the limit ring 62 are both tapered. The limit ring 62 can rotate around the central axis of the support ring 61, so that the limit ring 62 and the support ring 61 form a tubular structure, and the support ring 61 and the limit ring 62 limit the cable body 9. The staff sets the support ring 61 and the limit ring 62 in the laying groove 11, and the support ring 61 and the limit ring 62 are both in contact with the inner side wall of the laying groove 11, thereby increasing the coaxiality of the cable body 9 and the laying groove 11, and reducing the probability of the cable body 9 and the side wall of the laying groove 11 being damaged by contact friction.

[0049] After the cable body 9 is laid, the limiting ring 62 is rotated so that the limiting ring 62 and the supporting ring 61 overlap to form a semicircular ring, thereby facilitating the removal of the cable body 9 from the guide mechanism 6 .

[0050] Reference Figure 2 and Figure 7The end of the connecting rod 4 close to the rotating pin 41 is fixedly connected to the fourth supporting rod 7, the third adjusting screw 71 is internally threadedly connected to the fourth supporting rod 7, the end of the third adjusting screw 71 away from the fourth supporting rod 7 is hinged to a friction plate 72 that abuts against the side wall of the cable well 1, and the side wall of the third adjusting screw 71 is fixedly connected to a second handle 73. The staff rotates the second handle 73 around the central axis of the third adjusting screw 71, so that the third adjusting screw 71 rotates while moving along the axial direction of the fourth supporting rod 7, and the friction plate 72 moves synchronously with the third adjusting screw 71, thereby adjusting the distance between the friction plate 72 and the side wall of the cable well 1. Therefore, for cable wells 1 of different length and width specifications, the distance between the friction plate 72 and the rotating pin 41 is adjusted, so that the friction plate 72 can always fit the side wall of the cable well 1 to support the cable body 9.

[0051] Reference Figure 3 The first support rod 2 and the second support rod 3 are both threadedly connected with the fourth adjusting screw 8, and the bottom wall of the fourth adjusting screw 8 is hinged with a support plate 81, which abuts against the bottom wall of the cable well 1, and the support plate 81 and the first adjusting screw 22 are hinged by a ball joint. When the bottom wall of the cable well 1 has an inclination angle, the support plate 81 adapts to the top wall of the cable well 1 and rotates to a corresponding angle, so that the first support rod 2 and the second support rod 3 can be erected in the cable well 1 to support the cable body 9.

[0052] The implementation principle of a cable laying device according to an embodiment of the present invention is as follows: the cable body 9 is passed through the guide mechanism 6, and then the cable body 9 is laid in the laying groove 11 of the adjacent two side walls of the cable well 1, the cable body 9 is bent and abuts against the side wall of the limiting roller 43, and the first adjusting screw 22 is rotated to adjust the angle between the two connecting rods 4. The transmission screw 42 is rotated to adjust the distance between the support frame 5 and the side wall of the cable well 1, so that the support frame 5 abuts against the side wall of the cable well 1 to support the cable body 9. The third adjusting screw 71 is rotated to adjust the distance between the friction plate 72 and the side wall of the cable well 1, so that the support frame 5 abuts against the side wall of the cable well 1 to support the cable body 9.

[0053] In a second aspect, an embodiment of the present invention provides a cable laying method, which is applied to a cable laying device in the first aspect, and the laying method is:

[0054] S1, pass the cable body 9 through the guide mechanism 6, and then lay the cable body 9 into the laying grooves 11 of the adjacent two side walls of the cable well 1, the cable body 9 is bent and abuts against the side walls of the limiting roller 43, and the first adjusting screw 22 is rotated to adjust the angle between the two connecting rods 4;

[0057] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
