Description

Technical Field

[0001] The invention relates to the field of cable or electric cable installation, and in particular to a wiring device and a wiring method for an electrical automation system. Background Art

[0002] As a control component for automatic control of machines, the electrical automation system needs to use cables to connect different electrical equipment and mechanical equipment to achieve the purpose of automatic control. When wiring the automated instruments and equipment, the cables are generally routed along the corners of the mechanical equipment shell or the columns of the mechanical equipment. When wiring, it is necessary to leave enough margin for the cables to facilitate pulling the cables to install electrical boxes or add new instruments and equipment. There are two ways to reserve margins. One is to wind the cables in a spiral, but the spirally wound cables will be stacked with other cables, which is easy to cause knots and affect the pulling and use of the cables. The other way is to set extra margins at the corners of the cables and use springs to hang the extra cables on the housing of the equipment. Since only springs are used for pulling, once the reserved margin of the cables is large, the cables are easy to form S-shaped or wavy bends at the corners to accommodate more margins, making the cables more messy. Moreover, after the cable is pulled, it is difficult for the cable to reset automatically. After the cable is pulled, there is excess surplus at the connection part or the pulling end of the cable, which will affect the neatness of the cable and make it messy, affecting the subsequent inspection and construction.

DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Example 1

[0062] See also Figure 1-Figure 4 The present embodiment provides a wiring device for an electrical automation system, including a substrate 1. A mounting hole is provided on one side of the substrate 1. The substrate 1 is installed on electrical equipment, such as an automated lathe, an automated assembly line, a 3D printer, a photolithography machine, etc., by using bolts. A plurality of wire grooves are provided on the substrate 1. The wire grooves penetrate the bottom side wall of the substrate 1. When arranging cables, the wire grooves can be used to place wires. One main line can be placed in one wire groove. The wire grooves and the cables are limited to avoid interlacing and cluttering between the cables.

[0063] The rotating shaft 2 is fixedly installed on the side wall of the wire groove, and the two ends of the rotating shaft 2 are respectively fixed on the two side walls of the wire groove. A support frame 4 is rotatably installed on the outer side of the rotating shaft 2. The support frame 4 is an L-shaped structure. One end of the support frame 4 is rotatably connected to the rotating shaft 2, and the other end is a free end. The support frame 4 can rotate on the rotating shaft 2, and the free end of the support frame 4 is slidably installed with a first slider 9.

[0064] The active rod 3, one end of the active rod 3 is rotatably mounted on the outside of the rotating shaft 2, the rotation axis of the active rod 3 coincides with the rotation axis of the support frame 4, and the other end of the active rod 3 is slidably mounted on the first slider 9, such as Figure 1 As shown, the first slider 9 is a structure in which two rectangular blocks are arranged together, and the two rectangular blocks are connected together by rotating (or hinged) on one side where they are in contact. The two rectangular blocks are a through structure and are respectively inserted into one end of the active rod 3 and one end of the support frame 4. When the active rod 3 and the support frame 4 move relative to each other, the two rectangular blocks can rotate to change the angle between the active rod 3 and the support frame 4; the second slider 11 is also slidably mounted on the active rod 3. In this embodiment, a retaining ring is also fixedly mounted on the rotating shaft 2 to limit the support frame 4 and the active rod 3 to prevent the support frame and the active rod 3 from sliding horizontally on the rotating shaft 2.

[0065] The reset rod 12 is fixedly mounted with a second rotating shaft on the inner side wall of the wire groove, and the second rotating shaft is located directly below the support frame 4. One end of the reset rod 12 is rotatably connected to the second slider 11, and the other end of the reset rod 12 is rotatably connected to the second rotating shaft. In this embodiment, one end of the second rotating shaft is fixedly connected to the inner side wall of the wire groove, and the other end is suspended; when the active rod 3 rotates downward, the second rotating shaft will not cause motion interference to the active rod 3.

[0066] A spring 13 is sleeved on the outer side of the second rotating shaft, one end of the spring 13 is fixedly connected to the second rotating shaft, and the other end is fixedly connected to the shaft hole of the reset rod 12. The spring 13 provides a rebound force to the reset rod 12. In this embodiment, the spring 13 can be a torsion spring or a spring spring. Figure 3 As shown, in the natural state, the elastic force provided by the spring 13 to the reset rod 12 just makes the support frame 4 in the outermost position, as shown in FIG. Figure 7 In the state shown, the active rod 3 and the reset rod 12 are tilted to the upper left. In this embodiment, the reset rod 12 cannot be in a state perpendicular to the substrate 1. When the reset rod 12 is in a state perpendicular to the substrate 1, the active rod 3 is supported in the vertical direction, which will affect the rotation of the active rod 3. Therefore, in this embodiment, the active rod 3 and the reset rod 12 are tilted in the same direction.

[0067] The guide rod 8 and the third rotating shaft 81 are fixedly installed at the corner of the L-shaped support frame 4, one end of the guide rod 8 is rotatably connected to the third rotating shaft 81, an extension block is fixedly installed on the second slider 11, and the angle between the extension block and the second slider 11 is 90 degrees, forming a "T"-shaped structure, the other end of the guide rod 8 is slidably connected to the extension block, when the support frame 4 rotates around the rotating shaft 2, the guide rod 8 will slide together with the extension block, and the guide rod 8 will also move with the support frame 4, and a protrusion is fixedly installed at the free end of the guide rod 8, and the protrusion is located on the outside of the second slider 11, which can prevent the guide rod 8 from falling off the second slider 11.

[0068] The support wheel 7 is rotatably mounted on the third rotating shaft 81 at the corner of the L-shaped support frame 4, and the first slider 9 is fixedly mounted with a rotating shaft, and the support wheel 7 is also rotatably mounted on the rotating shaft. Figure 1 and Figure 2 As shown, the two support wheels 7 are located on the same vertical plane.

[0069] A U-shaped limit block 10 is rotatably mounted on the outer side of the support wheel 7, and a rotating ring of annular structure is fixedly mounted on one end of the opening of the limit block 10. The rotating ring is rotatably mounted on the shaft hole of the support wheel 7, and the rotating ring is coaxially arranged with the shaft hole. The limit block 10 can rotate freely on the outer side of the support wheel 7, such as Figure 1 and Figure 2 As shown, a threading space for inserting cables is formed between the limit block 10 and the circumferential surface of the support wheel 7. The threading space should be larger than the diameter of the cable to facilitate threading. The cable passes between the limit block 10 and the support wheel 7. The limit block 10 can prevent the cable from falling off the support wheel 7.

[0070] In this embodiment, a protective ring 14 is also included. The protective ring 14 can be made of metal, plastic, or rubber. An extension ring is fixedly installed on the outside of the protective ring 14. The outer diameter of the extension ring is greater than the distance between the support wheel 7 and the limit block 10, which can prevent the protective ring 14 from falling off the support wheel 7. When the protective ring 14 is made of plastic or rubber, it has a certain elasticity. The protective ring 14 is a hollow cylindrical structure with openings at both ends. The circumferential surface of the protective ring 14 is provided with an opening arranged along the axial direction, and the opening is used to open the protective ring 14. The opening can be opened under the action of external force, and the cable can be put into the inside of the protective ring 14 from the opening. The inner ring of the protective ring 14 is glued together with the cable. When the protective ring 14 is made of metal, the inner ring diameter of the protective ring 14 is slightly smaller than the outer diameter of the cable, so that the cable can be clamped and the installation with the cable is more stable. The protective ring 14 is composed of two arc-shaped pieces with a semicircular structure. One side of the two arc-shaped pieces is rotatably connected by a rotating shaft, and the other side is an open end. The open ends of the protective ring 14 are connected together by bolts. When the metal protective ring 14 is installed on the outside of the cable, the two arc-shaped pieces are opened, and the cable is placed between the two arc-shaped pieces. Then, the protective ring 14 is connected with bolts. The protective ring 14 clamps the cable inside it, and the installation between the protective ring 14 and the cable is completed.

[0071] When wiring and routing electrical automation equipment, cables are generally arranged along the corners of the electrical equipment to facilitate hiding the cables. At the same time, the corners will also wrap the cables on both sides, which also has a certain protective effect on the cables. Therefore, in this embodiment, when wiring the electrical equipment, the cables are also chosen to be wired and routed at the corners of the electrical equipment. In addition, when wiring, it is necessary to reserve a suitable length for the cables to adapt to the changes in the positions of electrical components, and to facilitate the installation or modification of other equipment. At the same time, the reserved margin can also be used to compensate for thermal expansion and contraction caused by temperature changes. At present, during construction, the cables are often spirally wound together, or the cables are pulled by springs, and the cables are often in a scattered state.

[0072] In this embodiment, vertical wiring is taken as an example: Figure 3 As shown, the cables are routed along the vertical corners of the electrical equipment, and the base plate 1 is fixed to the top of the electrical equipment by bolts as the top outlet. In the initial state, the support frame 4 is tilted to the side away from the horizontal routing direction of the cable. The support wheel 7 on the third rotating shaft 81 is located below the support wheel 7 on the first slider 9, and the active rod 3 and the reset rod 12 are both in a state of tilting to the upper left, the guide rod 8 and the active rod 3 remain vertical, and the protrusion at the free end of the guide rod 8 contacts the second slider 11, as shown in FIG. Figure 3 Status shown.

[0073] When wiring, the cables are arranged upward along the vertical corners of the electrical equipment (or the wire troughs at the corners). When the cables are arranged to the top of the electrical equipment, they are routed along the outside of the support frame 4, and the top of the cables are passed through the threading space of the two support wheels 7. After the cables come out from the upper support wheel 7, they are routed along the horizontal corners of the electrical equipment (i.e., horizontal routing). The cables are routed along the support frame 4 and pass through the support wheel 7, leaving a pulling margin for the cables. Compared with spiral winding or using springs to pull the cables, the cables are routed along the support frame 4, so there will be no scattered cables, and in the natural state (such as Figure 3 As shown in the figure, the entire cable is in a taut (or just straight) state, without any natural bending or winding, making the cable layout more organized and neater.

[0074] After the cables are arranged on the support wheels 7, the protection ring 14 is installed on the cables between the two support wheels 7 to complete the installation of the protection ring 14. The cables can then be horizontally arranged and wired.

[0075] like Figure 3-Figure 6 As shown by arrow a, when the cable starts to be pulled (such as Figure 3 The status and Figure 7 As shown in FIG. 1 ), the force generated by the cable will first act on the support wheel 7 of the support frame 4, and this force will cause the support frame 4 to rotate around the rotating shaft 2, as shown in FIG. Figure 3 As shown by the dashed arrow c; since the first slider 9 is connected to the support frame 4 and the active rod 3 at the same time, when the support frame 4 rotates, the active rod 3 limits the first slider 9, and the support frame 4 will slide inward on the active rod 3 with the first slider 9, such as Figure 3 As shown by the arrow b in the middle, the active rod 3 will also rotate around the rotating shaft 2, and the first slider 9 will gradually move inward to the extreme position at the end of the support frame 4, and the first slider 9, the support frame 4, and the active rod 3 will rotate together. Figure 8 As shown, the second slider 11 slides upward along the active rod 3 and rotates around the third rotation axis 81 with the guide rod 8, and the guide rod 8 always remains perpendicular to the second slider 11. The guide rod 8 has a guiding function here. When the active rod 3 rotates to a vertical state (such as Figure 4 The status and Figure 8 As shown in FIG. 1 ), when the first slider 9 slides inward on the active rod 3 to the limit position, as shown in FIG. Figure 8 In the state shown, the active rod 3 and the reset rod 12 overlap on the vertical plane, and at the same time, the protection ring 14 contacts the support wheel 7 on the first slider 9. Since the support frame 4 rotates around the rotating shaft 2, the cables on the support frame 4 are in a loose state. In this state, the guide rod 8 moves to the farthest end of the active rod 3, and the guide rod 8, the active rod 3 and the support frame 4 form a smallest right-angled triangle structure, as shown in FIG. Figure 8 As shown in figure m, since the guide rod 8 is provided, during the movement, the length of the guide rod 8 changes with the position of the second slider 11 on the active rod 3 and changes the size of the right-angled triangle structure, which can avoid jamming between the active rod 3 and the support frame 4.

[0076] As the cable is pulled continuously, driven by the protection ring 14, the protection ring 14 and the cable, together with the first slider 9 and the upper support wheel 7, will continue to rotate to the right with the active rod 3. The triangle formed between the guide rod 8, the active rod 3 and the support frame 4 gradually becomes larger.

[0077] In this embodiment, a stopper 101 is fixedly mounted on the base plate 1, and the thickness of the stopper 101 is less than the thickness of the support frame 4. Since the cable is in a loose state on the support frame 4, the force on the support wheel 7 on the support frame 4 disappears, that is, the support frame 4 is in a state of no force, and the force of the cable only acts on the support wheel 7 of the first slider 9. As the cable is pulled, the cable will continue to rotate with the support frame 4 and the active rod 3, and the support frame 4 will rotate to the extreme position, such as Figure 5 and Fig. 9 In the state shown, the block 101 supports the support frame 4 so that the support frame 4 will not continue to rotate to the right, and at the same time, the cables of the support frame 4 are in the loosest state. However, since the protective ring 14 is stuck with the support wheel 7 on the first slider 9, as the cable is pulled, the cable will continue to slide on the L-shaped support frame 4 with the first slider 9, and continue to rotate around the shaft 2 with the active rod 3. At the same time, the second slider 11 will move along the active rod 3 in the direction close to the shaft 2, and the second slider 11 will rotate around the second shaft with the reset rod 12. At the same time, the second slider 11 also rotates around the third shaft 81 with the guide rod 8. The second slider 11 moves to the farthest end of the guide rod 8, and the first slider 9 also moves to the farthest end of the support frame 4 and the active rod 3. Figure 6 and Fig.10 The state shown. During the movement period when the support frame 4 and the active rod 3 rotate around the rotating shaft 2, the first slider 9 will slide inward while following the rotation of the support frame 4 and the active rod 3. The movement speed of the first slider 9 is relatively slow. After the support frame 4 stops rotating, the first slider 9 will slide outward on the support frame 4 and the active rod 3, and the cable will move and tighten on the support frame 4. The first slider 9 has only one movement mode of sliding, which is also more labor-saving for the force-applying personnel. When the same force is used to pull the cable, the cable moves faster. Therefore, when pulling the cable, the sudden increase in movement speed has a warning effect on the force-applying personnel, and can be used to remind the force-applying personnel that the cable has been pulled to the reserved margin to avoid excessive pulling. After the cable is pulled, new equipment and instruments can be connected to the cable.

[0078] During the process of pulling the cable, the active rod 3 rotates with the reset rod 12 around the second rotation axis, which causes the spring 13 to generate a restoring elastic force on the reset rod 12 .

[0079] After releasing the pulling force applied to the cable, under the action of the rebound force generated by the spring 13, the reset rod 12 rotates upward around the second rotating shaft, and the reset rod 12 slides the second slider 11 outward on the active rod 3, and at the same time, it rotates the active rod 3 to the left around the rotating shaft 2, and the active rod 3 slides the first slider 9 to the left on the support frame 4, and the first slider 9 moves to the inner limit position on the support frame 4 ( Fig. 9 L point in the middle, the limit position is designed according to the actual design parameters and is related to the length and position of the reset rod 12). In this embodiment, when the first slider 9 is just in the limit position on the support frame 4, it is the first reset stage. As the reset rod 12 rotates, the active rod 3 continues to rotate upward, and the active rod 3 rotates leftward around the rotation axis 2 with the first slider 9 and the support frame 4. At the same time, the second slider 11 moves to the farthest end on the active rod 3 and then moves to the side of the active rod 3 close to the rotation axis 2 (that is, moves to the inner side of the active rod 3). Fig.11 As shown, when the second slider 11 moves toward the inside of the active rod 3, the guide rod 8 follows the second slider 11 to slide toward the inside of the active rod 3. Since one end of the guide rod 8 is rotationally connected to the third shaft 81 at the corner of the support frame 4, and there is an angle between the guide rod 8 and the support frame 4, when the guide rod 8 follows the second slider 11 to slide toward the inside of the active rod 3, the guide rod 8 provides a leftward rotation force to the support frame 4, and the support frame 4 continues to rotate around the shaft 2 to the initial state. The process of rotating and resetting the support frame 4 is the second resetting stage. In the second resetting stage, the support frame 4 generates a pulling force on the cable, and rolls the cable on the support wheel 7 until the support frame 4 returns to its initial state. The pulled cable can be tightened to achieve cable resetting.

[0080] In the first reset stage, the protection ring 14 is always in contact with the support wheel 7 on the first slider 9, and because the movement of the first slider 9 is not in the same straight line as the center of the active rod 3, it has the characteristic of quick return. In the initial stage of wire collection, since the cables are pulled longer and piled up more, in the first stage, the cables can be quickly pulled and wound up, which can quickly reduce the accumulation of cables without causing excessive pulling on the cables. In the second reset stage, the wire collection is mainly carried out by rotating the support frame 4, which rotates around the shaft 2. At the same time, the first slider 9 slides outward on the support frame 4 and the active rod 3, and the rotation speed is relatively slow, which can achieve slow wire collection of the cables.

[0081] When winding up the wires, there are more cables piled up in the initial stage of winding up. You can wind up the wires quickly, and then slowly wind them up to achieve segmented winding up. This can improve the efficiency of winding up the wires, and at the same time reduce excessive pulling on the cables when winding up the wires.

[0082] Example 2

[0083] When wiring the electrical automation system, external cables are required to connect electrical equipment and control cabinets. External cables are generally placed in a floor trough, or placed in a metal wire trough, and the wire trough is fixed on the workshop (or the top of the room), and the cables are arranged on the top. The common method is to pass the cables through the wire trough and set them on the top of the workshop. In this embodiment, the cables are connected to electrical equipment and control cabinets in a top-running manner.

[0084] Therefore, in this implementation, if Fig.12 As shown, the wiring rack 15 is a rectangular parallelepiped structure with openings on the upper side and both ends. The wiring rack 15 is horizontally installed on the top of a workshop or indoors by bolts. A base plate 1 is fixedly installed at the outlet end of the wiring rack 15, and structures such as a support frame 4, an active rod 3, a first slider 9, a second slider 11, a reset rod 12, a guide rod 8 and a support wheel 7 are arranged on the base plate 1. The connection method between the above structures is the same as that in Example 1, and will not be repeated here.

[0085] like Figure 13-Figure 16 As shown in the figure, it is an installation structure diagram of the base plate 1, the wiring rack 15 and the cables. The wiring rack 15 is installed horizontally, and the base plate 1 is fixedly installed at the outlet end of the wiring rack 15; and it is kept on the same plane with the bottom of the wiring rack 15. After the cables pass through the wiring rack 15, they are routed or wired downwards through the support frame 4 and two support wheels 7. After the cables pass through the support frame 4 at the outlet end of the wiring rack 15, there is a pulling margin. When wiring, the cables can be pulled for wiring. At the same time, Figure 13-Figure 16 As shown, after the cable at the outlet end of the wiring rack 15 is supported by the support frame 4, the cable and the wiring rack 15 are not in contact with each other, so when the cable is pulled, the outlet of the wiring rack 15 can be prevented from causing damage to the bending part of the cable.

[0086] When laying or wiring external cables, multiple cables need to be placed in the wiring rack 15. Multiple wire clamping plates 16 are installed on the wiring rack 15 using bolts. The wire clamping plates 16 have a U-shaped slot opening downward. The cables can be placed in the U-shaped slot to fix the cables.

[0087] When placing external cables inside the wiring rack 15, the wiring rack 15 is generally fixed in a corresponding position first, and then the cables are placed in the wiring rack 15 for wiring. When placing the cables, it is necessary to ensure that there is no stacking or crossing between the cables to facilitate the wiring of the cables. Therefore, during construction, the cables need to be laid or arranged in the wiring rack 15 one by one, and then marked accordingly, and then the remaining cables are laid or arranged in sequence. After the cables are placed inside the wiring rack 15, the cables need to be sorted to avoid details or crossing between the cables, which is quite troublesome when laying.

[0088] Therefore, in this embodiment, a cable management unit is also provided for arranging cables. Fig.17 and Fig.18 As shown, the cable management unit includes a cable management box 17, and a plurality of cable management slots 23 are provided at the bottom of the cable management box 17. The cable management slots 23 are open at the bottom, and one cable is placed in each cable management slot 23. The cable management box 17 has two sides with slots 171 matching the cable rack 15. The slots 171 can be stuck on the outside of the cable rack 15, and the inner side wall of the slots 171 is rotatably mounted with four rollers 22, such as Fig.18 As shown, one of the rollers 22 is a driving wheel, and a hub motor is installed inside the driving wheel, and the hub motor drives the driving wheel to rotate. When the cable management box 17 and the cable rack 15 are installed together, the four rollers 22 are in contact with the outer wall of the cable rack 15, and when the driving wheel rotates, it can drive the cable management box 17 to move horizontally on the cable rack 15.

[0089] After the cables are laid, arranged or placed inside the wiring rack 15, the cable management box 17 is installed at one end of the wiring rack 15, and the cables at one end of the wiring rack 15 are installed together with the cable management trough 23. One cable is placed in a cable management trough 23, and then the drive motor can be started. The drive motor drives the cable management box 17 to move along the wiring rack 15. When the cable management trough 23 moves with the cable management box 17, under the action of the cable management trough 23, the stacked or superimposed cables will be separated and arranged in a straight line or similar to a straight line along the movement direction of the cable management trough 23. The superimposed cables or crossed cables can be neatly arranged, which is convenient for subsequent marking or wiring of the cables.

[0090] However, during actual construction, it was found that if multiple cables placed in the wiring rack 15 are severely stacked or crossed, only the cable management trough 23 is used for cable management. The side walls of the cable management trough 23 will cause certain damage to the insulating sheath of the cables, affecting the service life of the cables. Therefore, along the forward direction of the cable management box 17, a swinging part is also provided at the front end of the cable management box 17, and the swinging direction of the swinging part is perpendicular to the forward direction of the cable management box 17.

[0091] The specific setting of the swing part is as follows: Fig.18 and Fig.19 As shown, the swinging part includes a swinging rod 19, on which a plurality of shifting blocks 24 are fixedly mounted. The shifting blocks 24 extend downward and are flush with the bottom of the cable management groove 23, and the shifting blocks 24 are placed between two adjacent cables.

[0092] The wire management box 17 is provided with a through opening, in which the shifting block 24 is located, and a protective shell 18 is also provided on the outside of the swinging rod 19. The protective shell 18 is fixedly connected to the top of the wire management box 17 and covers the through opening. One end of the swinging rod 19 extends out of the protective shell 18, and a rotating wheel is rotatably installed at one end of the swinging rod 19 located outside the protective shell 18; the other end of the swinging rod 19 is located inside the protective shell 18, and a supporting spring 21 is fixedly installed between the other end of the swinging rod 19 and the side wall of the protective shell 18 to support The spring 21 provides an elastic force pointing to the rotating wheel to the swing rod 19; a cam 20 is rotatably installed on the top of the wire management box 17, and the eccentric raised surface of the cam 20 is in contact with the rotating wheel. The driving wheel is installed inside the wire management box 17 just below the cam 20, and the rotating shaft of the driving wheel is fixedly connected to the eccentric shaft of the cam 20. When the driving wheel rotates, it can rotate with the cam 20, and the rotation of the cam 20 can realize eccentric movement. When the cam 20 rotates, it can swing the swing rod 19 and the shift block 24 in the through-hole of the wire management box 17.

[0093] When the cable management box 17 is installed with the cable rack 15, the bottom of the shift block 24 contacts the bottom of the inner cavity of the cable rack 15. When the driving wheel rotates, the cable management box 17 moves along the length direction of the cable rack 15. At the same time, the swing rod 19 and the shift block 24 swing in a direction perpendicular to the cable management box 17. For cables stacked or crossed together, the stacked or crossed cables can be separated under the swinging action of the shift block 24. Moreover, since the shift block 24 is located at the front end of the cable management groove 23, the cables are combed apart before entering the cable management groove 23. Under the swinging action of the shift block 24, the stacked or crossed cables are separated, so that a certain distance is left between the cables for the cable management groove 23 to pass through, which can avoid the cable management groove 23 from damaging the insulation sheath of the cables. Driven by the forward movement of the cable management groove 23, the distance between the combed cables can be basically kept consistent. After the cable management is completed, one end of the cable can be installed and laid or arranged downward from the support frame 4 and the support wheel 7.

[0094] In this embodiment, the cables cannot be connected to the support frame 4 and the support wheel 7 before they are arranged inside the wiring rack 15. Therefore, when wiring, the outlet end needs to be directly placed in the wire groove and suspended, and the limit block 10 on the support wheel 7 is in an open state from the support wheel 7, such as Fig. 20As shown, the upper side wall corresponding to the opening of the limit block 10 and the two sides of the limit block 10 are detachably connected by bolts. After the cables on the wiring rack 15 are arranged, the limit block 10 is opened, the cables are placed on the support wheel 7, and then the upper side wall and the two sides of the limit block 10 are installed, and the cables can be placed on the support frame 4 and the support wheel 7 to achieve support for the cables and ensure that the cables have a stretch margin.
