Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a wiring device for low-voltage lines in power engineering. Background Technology

[0002] In the field of power engineering construction, standardized wiring can not only save space in the power distribution room, but also prevent wires from getting tangled, reduce safety hazards caused by messy wiring, and facilitate subsequent circuit maintenance. Therefore, wiring racks are used to lay wires in low-voltage power distribution rooms to meet wiring standard requirements.

[0003] Currently, wiring in power distribution rooms mostly uses wire racks, with wiring channels installed on the wire racks. The wire racks provide support, and the wiring channels can position and fix the lines to meet the requirements of the line layout. The wiring channels are generally fixed in the wire racks by setting fixing holes according to the pre-planned line path, and then bolts are inserted into the fixing holes to fix the wire racks on the wire racks. Then the wiring is laid in the wiring channels.

[0004] However, in actual construction, due to various uncertainties, when minor adjustments are needed to the wiring path, it is necessary to make lateral adjustments to individual wiring channels. The above construction method requires drilling fixing holes again on the changed path along the cable rack and then adjusting the position of the wiring channel, which is not convenient. Utility Model Content

[0006] To achieve the above objectives, the technical solution of this utility model is: a low-voltage wiring device for power engineering, comprising:

[0007] The crossbeam has T-slots along its length.

[0008] The wiring channel includes a first base plate and two upper side plates that are parallel and spaced apart on the first surface of the first base plate. The first base plate is connected with at least two first bolts.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] To achieve the above objectives, the technical solution of this utility model, as shown in the reference figure, is: a low-voltage wiring device for power engineering. Figures 1-4As a specific implementation method, the wiring device includes:

[0031] The crossbeam 1 has a T-slot 11 along its length;

[0032] The wiring trough 22 includes a first base plate 220 and two upper side plates that are parallel and spaced apart on the first surface of the first base plate. The first base plate 220 is connected with at least two first bolts 32.

[0033] The T-slot 11 is slidably fitted with a limiting plate 31, and the end of the first bolt 32 is connected to the limiting plate 31.

[0034] Specifically, during construction, the crossbeam 1 can be installed on the wire frame or used as a structural component of the wire frame. The laying direction of the crossbeam 1 is perpendicular to the laying direction of the line. Then, the limiting plate 31 is set in the T-slot. In a specific embodiment, the limiting plate 31 is welded to the end of the first bolt 32. Then, the wiring trough 22 is fixed to the crossbar by the first bolt to achieve the purpose of fixing. With this setting, when it is necessary to make a lateral fine adjustment to the position of the wiring trough 22, the locking part connected to the first bolt can be loosened. At this time, the first bolt, the limiting plate 31 and the wiring trough can all slide and adjust along the guide direction of the T-slot 11, which facilitates position adjustment and improves the convenience of construction. After adjustment, the wiring trough can be locked again. Then, wiring is laid between the two upper side plates 222 that are set parallel to each other in the wiring trough. Then, the wiring harness is pressed to complete the wiring. The method of pressing the wiring harness is described below.

[0035] Furthermore, as a specific implementation, in order to facilitate the connection and adjustment of the wiring trough and the crossbeam, the wiring device provided in this application also includes a base 21, including a second base plate 210 and a support plate 211 spaced apart on the second base plate 210. The second base plate is provided with third through holes 212 on both sides of the support plate, which cooperate with the first bolt 32. The wiring trough 22 is detachably and fixedly connected to the base 21.

[0036] Specifically, this design allows for a detachable and fixed connection between the base and the wiring channel. During construction, the base can be connected to the first bolt first, and then a suitable wiring channel can be selected based on the wiring specifications, improving construction convenience. When selecting a wiring channel, the height of the upper side plate 222 should be slightly larger than the diameter of the wiring, generally by 1-2 millimeters. The difference between different wiring channel specifications lies in the height of the upper side plate 222; the distance between the two upper side plates remains constant. The base includes a second base plate 210, which has a third through hole 212 that matches the first bolt. During base installation, the upper end of the first bolt passes through the third through hole 212, and then the first nut 33 is locked onto the first bolt to secure the base.

[0037] Furthermore, as a specific implementation method, refer to Figures 3-6 The first base plate 220 has second through holes 225 on both sides of the two upper side plates, and the second base plate 210 has two second nuts 217 corresponding to the two second through holes 225. With this arrangement, after the base and the crossbeam are fixedly connected, the wiring channel can be placed on the base, and then the second bolt 41 is passed through the second through hole 225 and locked to the second nut 217 to fix the wiring channel. This fixing method is convenient for installation.

[0038] Furthermore, as a specific implementation method, refer to Figures 3-6 The lower surface of the first base plate 220 is provided with two positioning protrusions 224 corresponding to the two upper side plates. The upper end of the upper side plate 222 is provided with a positioning groove 223. On both sides of the two positioning protrusions 224, the lower surface of the first base plate 220 is provided with two lower side plates 221, and the height of the lower side plates is equal to the height of the upper side plates. Specifically, by setting positioning protrusions 224, lower side plates, and positioning grooves 223, multiple wiring grooves can be stacked on the base according to the wiring requirements during the construction process. During the stacking process, the upper positioning protrusions correspond to the lower positioning grooves 223. The lower side plate of the upper wiring groove abuts against the first base plate 220 of the lower wiring groove, and the first base plate of the upper wiring groove can press and position the wiring harnesses laid below. After the wiring is completed, the second bolts 41 of appropriate length are passed through the second through holes 225 on the stacked wiring grooves in sequence, and then locked on the second nut 217 on the base. Generally, during construction, no wiring harnesses are laid between the upper side plates of the uppermost wiring groove, which mainly serve to press and position the wiring harnesses in the lower wiring groove.

[0039] Specifically, the wiring trough is preferably made of aluminum alloy, which is lightweight, high-strength, and has good thermal conductivity, enabling it to dissipate the heat generated by the wiring harness in a timely manner.

[0040] Furthermore, as a specific implementation method, refer to Figure 3 , Figure 4 , Figure 6 Two support side plates 213 are arranged parallel to each other on the side of the support plate 211 opposite to the second base plate 210. Each support side plate 213 has a support positioning groove 214 at its end. The distance between the two support side plates 213 is equal to the distance between the two upper side plates. Specifically, by setting two support side plates 213 on the base, the wiring channel can be supported by contact with the second base plate of the wiring channel when it is installed above. The support positioning groove 214 cooperates with the support positioning protrusion 224 of the wiring channel for positioning, thereby enabling the wiring harness to be laid between the two support side plates 213.

[0041] Furthermore, as a specific implementation, on both sides of the two supporting side plates 213, the supporting plate 211 is provided with two first through holes 215, and two second nuts 217 are provided on the lower surface of the supporting plate 211 corresponding to the two first through holes.

[0042] Specifically, by placing the second nut on the lower surface of the support plate 211, the second nut can be hidden. The support plate 211 and the second base plate 210 are spaced apart, and there is a certain distance between the second nut and the second base plate. Therefore, when the second bolt 41 is locked onto the second nut, there is a space between the second nut and the second base plate. After the second bolt and the second nut are screwed together, they can still be screwed down a certain distance to ensure effective locking. Furthermore, when the length of the second bolt is too long, the end of the second bolt can be accommodated by the space.

[0043] Furthermore, as a specific implementation, on both sides of the support plate 211, the second base plate 210 is provided with two third through holes 212. The first bolt 32 passes through the upper end of the third through hole 212 and is threaded to a first nut 33. A rigid plate seat 34 is provided between the first nut 33 and the second base plate 210. The rigid plate seat can be adjusted in the vertical direction.

[0044] Furthermore, the lower surface of the rigid plate base 34 includes a first inclined surface 341, and a movable member 36 is provided below the first inclined surface. The movable member includes a second inclined surface 361 that cooperates with the first inclined surface. The lower surface of the movable member is slidably engaged with the second base plate 210, and a pull rod 35 is provided between the movable member and the base 21.

[0045] For details, please refer to Figure 3 , Figure 4 , Figures 7-9Along a direction parallel to the second base plate, a fourth through hole 216 is provided through the base. The pull rod 35 is guided through the fourth through hole 216. The third through hole 212 includes two holes respectively located on both sides of the support plate 211. The first bolt 32 includes two holes corresponding to the third through holes. The rigid plate seat 34 includes two holes respectively fitted onto the two first bolts, and the first inclined surfaces on the two rigid plate seats are arranged opposite to each other. When the rigid plate seat 34 is fitted onto the first bolt, its side abuts against the base. One of the two movable parts 36 is provided with a second nut 352. One end of the pull rod 35 is provided with a bolt head 351, and the other end is provided with a threaded part that is threaded to the second nut. During assembly, the rigid plate seat 34 is first fitted onto the first bolt 32, and then the first nut 33 is threaded onto the first bolt and pre-tightened, so that the limiting plate and the rigid plate seat clamp the T-slot. Then, the assembly proceeds in the opposite direction. Rotate the first nut 33 upwards along the first bolt by 4-6 mm. Then, by passing the threaded end of the pull rod through one movable part 36, the fourth through hole 216, and another movable part 36 in sequence, it is threadedly connected to the second nut. Rotate the pull rod 35 through the bolt head 351, and the second nut is tightened and screwed onto the threaded part. At this time, the bolt head and the second nut can provide a mutual pressing force to the two movable parts 36. The second inclined surfaces of the two movable parts 36 press against the first inclined surfaces of the two rigid plate seats, causing the rigid plate seats to shift upwards, compensating for the 4-6 mm upward movement of the first nut. This allows the limiting plate to abut against the T-slot opening and lock the base, achieving the purpose of locking the base. In this way, when it is necessary to adjust the position of the wiring groove later, the second nut can be rotated a certain distance by rotating the bolt head at the end of the pull rod. Figure 8 A first retaining spring 353 is provided on the side of the pull rod near the bolt head, and another movable part 36 is provided with a receiving groove 362 for accommodating the second nut 352. A second retaining spring 354 is provided at the opening of the receiving groove. At this time, a pushing force can be applied to one movable part by the first retaining spring, and a pushing force can be applied to the second retaining spring by the second nut, so that the two movable parts 36 are offset in a direction away from each other, thus loosening the locking of the base. This makes it easy to adjust the displacement of the base. With this setting, the bolt head 351 can be placed on the side of the wiring groove that is relatively open, which is convenient for subsequent adjustment. This method can deal with the working condition where the wiring distance between two adjacent wiring grooves is close and it is not convenient to adjust the first nut. In this embodiment, the first nut 33 is a nut with a rubber ring, which can be well held in the position on the first bolt.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
