Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and specifically discloses a laying and installation device for bending cables in a power distribution cabinet. Background Technology

[0002] Cable bending is an important step in the installation and laying of cables. There are several main types of cable bending methods: Large bends, which use a large bending radius to create a smooth arc at the bend. Advantages include easy cable pulling and maintenance, protection of the wires, and a neat appearance. Disadvantages include high cost and difficult construction. Small bends, which use a small bending radius, result in a more compact cable laying and are relatively simple to install, but are more difficult to pull and time-consuming. Point-to-point cabling uses the shortest straight-line distance between installation points, saving labor, time, and materials while also making cable pulling easier. However, disadvantages include messy and irregular wiring that can easily damage the conduit.

[0003] The invention disclosed in CN107039923B is a cable bending and shaping device, including a fixed platform and a first cylinder and a second cylinder symmetrically arranged above and below the fixed platform. A first column and a second column are fixed above the fixed platform, and both are on the same straight line as the first cylinder. A first rotating arm, a second rotating arm, and a shaping disc are sequentially mounted on the first column. Rotating wheels are connected to the upper ends of the first and second rotating arms, and rotating bearings are connected to the fixed platform below the ends. The rotating bearings have an arc-shaped opening on the movement path of the fixed platform. A T-shaped push handle is fixed to the end of the piston rod of the second cylinder, and the T-shaped push handle is sleeved with the rotating bearing. The second column is located outside the arc-shaped opening and has a positioning wheel. Although this invention can effectively bend cables during cable installation, it lacks portability and the overall device occupies a large area, making it unsuitable for small-scale operating environments, such as cable bending inside a distribution cabinet. Because the space inside the distribution cabinet is small and there are many cables, the laying and arrangement of cables inside the distribution cabinet is particularly important. On the one hand, the connection direction of the cables needs to be clear and easy to understand. On the other hand, the laying and installation of cables needs to minimize the space occupied inside the distribution cabinet. Therefore, neatness and compactness are key. As a result, this device is extremely inadequate when used to bend and install cables inside the distribution cabinet.

[0004] However, current cable bending installation equipment for distribution cabinets generally uses manual bending, which is inefficient, time-consuming, and labor-intensive. Furthermore, manual bending often results in inconsistent cable curvature, leading to a messy and unsightly cable arrangement within the distribution cabinet, easily causing cable mixing and affecting its normal operation. Meanwhile, current semi-automatic or automatic cable bending equipment occupies a large area, making handheld operation inconvenient. Additionally, these devices require power, undoubtedly increasing operating costs. Therefore, cable bending equipment suitable for distribution cabinets that is compact, portable, and requires no power supply is crucial. Summary of the Invention

[0005] To address the problem of large axial temperature differences and excessively high local temperatures in current temperature control devices for glow discharge pyrolysis wastewater, this invention provides a laying and installation device for bending cables in a power distribution cabinet.

[0006] To address the above problems, the present invention provides the following technical solution:

[0012] Preferably, the push rod has an opening, and a sliding block is slidably connected inside the opening, the sliding block being fastened to the outer shell.

[0013] Preferably, the bending clamp includes a bending clamp head and a bending clamp seat that are fastened to the clamp arm. The outer side of the bending clamp head and the inner side of the bending clamp seat are provided with anti-slip grooves to prevent cable displacement. The top of the bending clamp head is provided with an arc-shaped protrusion, and the bottom of the inner side of the bending clamp seat is provided with an arc-shaped pressure groove.

[0014] Preferably, the radius of the protrusion is smaller than the radius of the groove, and the acute angle formed by the bent clamp is smaller than the acute angle formed by the inner side of the bent clamp seat.

[0015] Preferably, the bottom of the support frame is equipped with a detachable base, and a locking block is arranged on the top of the base, the height of the locking block being greater than the height of the locking slot.

Operators only need to rotate the lever to bend the cable, and the bending angle is a small arc, which facilitates the neat and compact installation of the cable in the power distribution cabinet and reduces the space occupied by the cable in the power distribution cabinet. Therefore, it has a very wide range of application prospects. Attached Figure Description

[0033] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] This specific embodiment provides a laying and installation device for bending cables in a power distribution cabinet, such as... Figures 1-10 As shown, a cable laying and installation device for a power distribution cabinet includes a gripper 1. The end of the gripper 1 is fastened to a support frame 2 for support. The support frame 2 consists of three vertical beams and two horizontal beams, with one vertical beam positioned in the middle of the side of the two horizontal beams. A rectangular through hole 4 is provided at the center of the top horizontal beam of the support frame 2, and a rectangular slot 5 is provided at the center of the bottom horizontal beam of the support frame 2.

The height of the locking block 19 is greater than the height of the slot 5, and the length and width of the locking block 19 are slightly smaller than the inner length and inner width of the slot 5. The base 18 is designed for easy placement when the device is not in use, saving space and facilitating retrieval.

[0035] The top of the support frame 2 is fastened to the outer shell 3. The bottom of the outer shell 3 has a U-shaped groove 20 with an open shape. The top of the groove 20 has an A through hole 21. A spring 13 for quick return to its original position is arranged in the groove 20.

The spring 13 is arranged above the support frame 2. Due to the limitation that the inner diameter of the spring 13 is larger than the inner length of the A through hole 21 and the B through hole 4, the spring 13 can only extend and retract vertically within the groove 20.

[0036] An anti-rotation yoke mechanism 6 is installed on the inner side of the support frame 2. The anti-rotation yoke mechanism 6 is arranged on the vertical beam at the middle position of the side of the crossbeam of the support frame 2. The anti-rotation yoke mechanism 6 includes a turntable 601 rotatably connected to the vertical beam of the support frame 2. A rotating rod 602 for rotating the turntable is fastened to the turntable 601. A slip ring 603 that can linearly move with the turntable 601 is sleeved on the rotating rod 602. The inner side of the slip ring 603 is hollow, and the rotating rod 602 is slidably connected to the inner side of the slip ring 603. A linearly displaceable transmission rod 604 is arranged on the outer side of the slip ring 603. The transmission rod 604 is along the Y-axis. The transmission rod 604 is oriented in a certain direction. A connecting hole 605 is provided at the end of the transmission rod 604 away from the slip ring 603. Two connecting holes 605 are provided. The transmission rod 604 is connected to a push rod 7 arranged along the Y-axis. A connecting part 16 is provided at the bottom of the push rod 7. A connecting buckle 17 is arranged on the connecting part 16. The connecting buckle 17 has a cylindrical structure, and two connecting buckles 17 are arranged. The connecting buckle 17 can be sleeved with the connecting hole 605. The transmission rod 604 is connected to the push rod 7 through the connecting hole 605 and the connecting buckle 17, and an outer shell 3 is bolted to the outside. The connecting hole 605 and the connecting buckle 17 are not easily detached.

[0037] The upper half of the transmission rod 604, i.e., the side away from the slip ring 603, has a smaller height than the lower half. The upper half of the transmission rod 604 is sleeved with the spring 13. The inner diameter of the spring 13 is smaller than the height of the lower half of the transmission rod 604. The upper half of the transmission rod 604 is arranged in the through hole A 21, and the lower half of the transmission rod 604 is arranged in the through hole B 4. The inner width and inner length of the through hole A 21 are smaller than the inner width and inner length of the through hole B 4. The transmission rod 604 can be linearly displaced along the Y-axis within the through hole A 21 and the through hole B 4.

[0038] The push rod 7 has an opening 14, and a sliding block 15 is slidably connected inside the opening 14. The sliding block 15 is fastened to the outer shell 3 by bolts. Push teeth 8 are provided on both sides of the push rod 7. The push teeth 8 are meshed with a drive gear 9. The drive gear 9 is meshed with a driven gear 10. The driven gear 10 and the push teeth 8 are arranged at intervals. The driven gear 10 is equipped with a clamping arm 11 for opening and closing. The clamping arm 11 is equipped with a bending clamp 12 for bending cables. There are two drive gears 9 and two driven gears 10, which are symmetrically arranged on both sides of the push rod 7. The clamping arm 11 is composed of two supporting arms, and the two supporting arms are respectively arranged on the driven gear 10. The drive gear 9 is arranged below the driven gear 10 along the Y-axis. The drive gear 9 and the driven gear 10 are rotatably connected to the outer shell 3 through a rotating shaft.

[0039] The bending clamp 12 includes a bending clamp head 1201 and a bending clamp seat 1202 that are fastened to the clamp arm 11. The outer side of the bending clamp head 1201 and the inner side of the bending clamp seat 1202 are provided with anti-slip grooves 1203 to prevent cable displacement. The top of the bending clamp head 1201 is provided with an arc-shaped protrusion 1204, and the bottom inner side of the bending clamp seat 1202 is provided with an arc-shaped pressure groove 1205. The radius of the arc of the protrusion 1204 is smaller than the radius of the arc of the pressure groove 1205, and the acute angle formed by the bending clamp head 1201 is smaller than the acute angle formed by the inner side of the bending clamp seat 1202.

[0040] The outer side of the bending clamp 1201 and the inner side of the bending clamp seat 1202 are provided with anti-slip grooves 1203, which can effectively prevent the cable from shifting or falling off during the bending process and avoid damage to the cable. At the same time, the top of the bending clamp 1201 is provided with an arc-shaped protrusion 1204, and the bottom of the inner side of the bending clamp seat 1202 is provided with an arc-shaped pressure groove 1205, which can protect the cable during the bending process, reduce the phenomenon of obvious creases on the cable surface, reduce the wear of the cable during the bending process, and improve the service life of the cable.

[0041] In summary, when the operator rotates the rotating rod 602, causing the turntable 601 to rotate, the slip ring 603 undergoes linear displacement along the Y-axis. At this time, the rotating rod 602 moves linearly within the slip ring 603 along the X-axis. The movement of the slip ring 603 causes the transmission rod 604 to move linearly along the Y-axis. When the transmission rod 604 moves upward along the Y-axis, the spring 13, located in the groove 20, is compressed by the lower half of the transmission rod 604. At this time, the push rod 7, connected to the transmission rod 604, moves upward along the Y-axis, which in turn pushes the gear 8 to rotate the meshing drive gear 9. The two drive gears 9 rotate in opposite directions, and the drive gear 9 then rotates the meshing driven gear 10. The two driven gears 10 rotate in opposite directions, causing the clamping arm 11 and the bending clamp head 1201 and bending clamp seat 1202 arranged on the clamping arm 11 to move closer to each other. The protrusion 1204 on the bending clamp head 1201 and the pressure groove on the bending clamp seat 1202 cooperate to perform the bending operation on the cable. After the cable bending operation is completed, the operator only needs to release the rotating rod 602. At this time, the compressed spring 13 quickly rebounds, causing the bending clamp head 1201 and bending clamp seat 1202 to move away from each other and return to their initial positions. At the same time, the push rod 7 and the transmission rod 604 also return to their initial positions. The rapid return of the spring 13 can save time and effort in the operation of the device, reduce the operator's operating intensity, and improve work efficiency.

[0042] Because the device occupies a small area, is highly portable, and is easy to operate, it is very suitable for scenarios with limited space and small operating range, such as power distribution cabinets. Operators only need to rotate the lever 602 to bend the cable, and the bending angle is a small arc, which facilitates the neat and compact installation of the cable in the power distribution cabinet, reducing the space occupied by the cable in the power distribution cabinet. Therefore, it has a very wide range of application prospects.

[0043] The working principle of this invention is as follows:

[0044] First, the operator places the cable to be bent between the bending clamp 1201 and the bending clamp seat 1202. Then, the operator rotates the rotating rod 602, causing the turntable 601 to rotate clockwise. Simultaneously, the rotating rod 602 moves linearly along the X-axis within the slip ring 603, while the slip ring 603 follows the turntable 601 and moves upward along the Y-axis. This causes the transmission rod 604, located on the upper side of the slip ring 603, to move upward along the Y-axis, simultaneously pressing the spring 13, which is located in the groove 20 and connected to the upper part of the transmission rod 604. Next, the push rod 7, connected to the transmission rod through the connecting hole 605 and the connecting buckle 17, moves upward along the Y-axis, causing the push teeth 8 on the push rod 7 to drive the meshing drive gear 9 to rotate. The two drive gears 9 rotate in opposite directions, and the rotation of the drive gear 9 in turn drives the meshing driven gear 10 to rotate. The two driven gears 10 rotate in opposite directions, causing the clamping arm 11, which is fastened to the driven gear 10, and the bending clamp head 1201 and bending clamp seat 1202 arranged on the clamping arm 11 to move closer to each other. The protrusion 1204 on the bending clamp head 1201 and the pressure groove on the bending clamp seat 1202 cooperate to bend the cable. At the same time, the anti-slip groove 1203 on the outer side of the bending clamp head 1201 and the inner side of the bending clamp seat 1202 can effectively prevent the cable from shifting or falling off during the bending process, thus avoiding damage to the cable. In addition, the top of the bending clamp head 1201 is provided with an arc-shaped protrusion 1204, and the bottom of the inner side of the bending clamp seat 1202 is provided with an arc-shaped pressure groove 1205, which can protect the cable during the bending process, reduce the appearance of obvious creases on the cable surface, reduce the wear of the cable during the bending process, and improve the service life of the cable.

[0045] After the cable bending operation is completed, the operator only needs to release the rotating rod 602. At this time, the compressed spring 13 will quickly rebound, causing the bending clamp 1201 and the bending clamp seat 1202 to move away from each other and return to their initial positions. At the same time, the push rod 7 and the transmission rod 604 also return to their initial positions. The spring 13, which allows each component to quickly return to its original position, makes the operation more time-saving and labor-saving, reduces the operator's workload, and improves work efficiency.

[0046] After use, staff can place the device on the base 18, that is, the slot 5 at the bottom of the support frame 2 is engaged with the block 19 at the top of the base 18, thereby reducing the storage space occupied by the device and making it easier to place the device and retrieve it for the next use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
