Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a multi-layer cable laying device for power engineering. Background Technology

[0002] Power engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. The laying of power cables is a crucial part of power engineering, and its quality and safety are directly related to the stable operation of the power system.

[0003] When laying cables, the route, routing method, and cable type need to be determined according to the actual situation and requirements of the site. Currently, a combination of cable trays and cable ties is commonly used for fixing. The cables are bundled and positioned every 3 meters or so. Although this can achieve the purpose of organizing and laying cables, the repeated disassembly and reassembly of the cable ties is extremely difficult when the number of cables is increased or decreased. Moreover, due to the large number and density of cables, the accumulation of heat will have a certain impact on the heat dissipation of the cables and the aging of the cables.

[0004] Therefore, in order to solve the above problems, a multi-layer cable laying device for power engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-layer cable laying device for power engineering, which can be quickly installed and disassembled according to the addition or removal of cables, and the cables can be separated and supported, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer cable laying device for power engineering, comprising a lower bracket, an upper bracket, and an intermediate bracket, wherein the intermediate bracket is located between the lower bracket and the upper bracket. Placement slots are provided on the upper side of the lower bracket, the lower side of the upper bracket, and both the upper and lower sides of the intermediate bracket. Support plates are installed inside each placement slot. Guide posts are installed at both ends of the upper surface of the lower bracket. Annular slots are uniformly formed along the axial direction on the circumferential side of each guide post. Guide holes for passing through the guide posts are provided at the ends of both the upper bracket and the intermediate bracket. A control component is installed on the upper side of the upper bracket, and arc-shaped clamping plates for engaging the annular slots are installed at both ends of the control component.

[0007] Specifically, the control component includes a knob and sleeves. A knob is rotatably mounted at the center of the upper side of the upper bracket. Two sleeves are fixedly mounted on the upper side of the upper bracket, and the two sleeves are symmetrically distributed on both sides of the knob. A first connecting rod is slidably mounted inside each sleeve. The ends of the first connecting rods that are far apart from each other are fixedly assembled with an arc-shaped clamping plate. A swing arm is fixedly mounted on both sides of the knob. A second connecting rod is rotatably mounted between the swing arm and the first connecting rod on the same side. A spring is sleeved on each of the first connecting rods, and the spring abuts against the arc-shaped clamping plate and the sleeve.

[0008] Specifically, the guide post at the annular groove forms a circumferential slope with an upper diameter smaller than the lower diameter, and the arc-shaped plate has a chamfer that matches the circumferential slope.

[0009] Specifically, the upper end of the guide post is provided with a first screw hole, the lower end of the guide post is provided with a screw post, and the upper surface of the lower bracket is provided with second screw holes at both ends.

[0010] Specifically, each side has 6 to 10 support plates evenly distributed along the horizontal direction.

[0011] Specifically, the cross-section of the support piece is V-shaped.

[0012] Specifically, the length of the support piece is at least 10 cm.

[0013] Specifically, countersunk holes are provided at both ends of the lower bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the manually operated control component can simultaneously control the snap-fit ​​relationship between the arc-shaped card plate and the annular card slot, which makes it convenient to change the fixing status of the lower bracket, the middle bracket and the upper bracket, and can be conveniently adjusted when adding or removing cables, thereby improving the efficiency of repeated disassembly and installation.

[0015] In addition, the multi-layered arrangement of the lower bracket, middle bracket, and upper bracket, along with the arrangement of each pair of support plates clamping the cable, can prevent heat accumulation, facilitate cable heat dissipation, and also prevent the cable from aging rapidly.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a multi-layer cable laying device for power engineering, including a lower bracket 1, an upper bracket 3, and an intermediate bracket 2. The intermediate bracket 2 is located between the lower bracket 1 and the upper bracket 3. Placement slots are provided on the upper side of the lower bracket 1, the lower side of the upper bracket 3, and the upper and lower sides of the intermediate bracket 2. Support plates 8 are installed inside the placement slots. The intermediate bracket 2 can be selected according to the number of cable layers to be laid. In this way, the upper bracket 3 and the uppermost intermediate bracket 2, the adjacent intermediate brackets 2, and the lower bracket 1 and the lowermost intermediate bracket 2 can all be used to press each layer of cable, and each cable is separated and fixed in the aligned support plates 8.

[0024] Guide posts 6 are installed at both ends of the upper surface of the lower bracket 1. The guide posts 6 are cylindrical and vertically arranged. Annular grooves 7 are evenly opened along the axial direction on the circumferential side of the guide posts 6. Guide holes for passing through the guide posts 6 are opened at the ends of the upper bracket 3 and the middle bracket 2. A control component 4 is installed on the upper side of the upper bracket 3. Arc-shaped locking plates 5 for engaging the annular grooves 7 are installed at both ends of the control component 4. The upper bracket 3 and the middle bracket 2 can be inserted and assembled above the lower bracket 1 along the guide posts 6, which can improve the installation accuracy and facilitate the quick alignment of each support piece 8. The control component 4 can make the two arc-shaped locking plates 5 have a force that moves them away from each other. The arc-shaped locking plates 5 will engage with the aligned annular grooves 7 to lock the position of the upper bracket 3 and the middle bracket 2. The control component 4 can be manually released from the engagement of the arc-shaped locking plates 5 with the annular grooves 7, thus facilitating quick disassembly.

[0025] Please see Figure 4The control component 4 includes a knob 46 and sleeves 42. The knob 46 is rotatably mounted at the center of the upper side of the upper bracket 3. Two sleeves 42 are fixedly mounted on the upper side of the upper bracket 3, symmetrically distributed on both sides of the knob 46. A first connecting rod 43 is slidably mounted inside each sleeve 42. The ends of the first connecting rods 43 that are far apart from each other are fixedly assembled with the arc-shaped locking plate 5. A swing arm 45 is fixedly mounted on both sides of the knob 46. A second connecting rod 44 is rotatably mounted between the swing arm 45 on the same side and the first connecting rod 43. A spring 41 is sleeved on each of the first connecting rods 43. The spring 41 abuts against the arc-shaped locking plate 5 and the sleeve 42. Between them; the spring 41 causes the two arc-shaped clamping plates 5 to have a force that moves them away from each other, so that the arc-shaped clamping plates 5 can be engaged with the aligned annular groove 7. At the same time, the first connecting rod 43, the second connecting rod 44 and the swing arm 45 have a tendency to return to the same axis. When the knob 46 is turned manually (clockwise or counterclockwise rotation of 20° to 30° is possible), the two swing arms 45 can swing with the knob 46. After being transmitted by the second connecting rod 44, they can pull the two first connecting rods 43 closer to each other along the sleeve 42, thereby moving the two arc-shaped clamping plates 5 closer to each other, so that the engagement between the arc-shaped clamping plates 5 and the annular groove 7 can be manually released.

[0026] Please see Figure 5 The guide post 6 at the annular groove 7 forms a circumferential slope with an upper diameter smaller than the lower diameter, and the arc-shaped clamping plate 5 has a chamfer that matches the circumferential slope. This shape of the annular groove 7 and the arc-shaped clamping plate 5 allows the upper bracket 3 to be pressed down directly for installation without turning the knob 46. The arc-shaped clamping plate 5 can automatically separate from the currently engaged annular groove 7 and automatically engage with the annular groove 7 that is realigned on the lower side. It also has a reverse braking capability, that is, the arc-shaped clamping plate 5 will not separate from the currently engaged annular groove 7 when it moves upward with the upper bracket 3.

[0027] The upper end of the guide post 6 is provided with a first screw hole 10, the lower end of the guide post 6 is provided with a stud 11, and the upper surface of the lower bracket 1 is provided with second screw holes at both ends. Multiple guide posts 6 can be connected end to end through the screw connection of the first screw hole 10 and the stud 11, thereby realizing the extension function to meet the needs of laying more layers of cables. The stud 11 on the lowermost guide post 6 is used to be screwed and installed with the second screw hole on the lower bracket 1.

[0028] The support plates 8 on each side are 6 to 10 evenly distributed along the horizontal direction, which can clamp 6 to 10 cables, making the overall width of the device reasonable and appropriate. In addition, the cross-section of the support plate 8 is V-shaped, which can clamp cables of different diameters, with good adaptability. Furthermore, the length of the support plate 8 is at least 10 cm, which can support, guide and clamp the cables over a longer distance, resulting in better laying effect.

[0029] Both ends of the lower bracket 1 are provided with countersunk holes 9; when the lower bracket 1 is installed on the wall, cable tray or ceiling frame, the bolts are installed through the countersunk holes 9 to fix the position of the lower bracket 1.

[0030] Working principle:

[0031] In use, install one of these devices approximately every 3 meters. First, fix the lower bracket 1 by using bolts that pass through the countersunk hole 9. Then, select the appropriate number of intermediate brackets 2 and guide posts 6 according to the number of cables. Pre-install the intermediate brackets 2 and upper brackets 3 through the guide posts 6. Each cable passes between the two corresponding support plates 8. After the cables are sorted, press down on the upper bracket 3. The control component 4 will then engage the arc-shaped clamping plate 5 with the aligned annular groove 7, thereby fixing the position of the intermediate brackets 2 and upper brackets 3. At this time, each cable is also clamped and fixed.

[0032] When it is necessary to increase or decrease the number of cables, manually turn knob 46. After being transmitted through swing arm 45, second connecting rod 44, and first connecting rod 43, the two arc-shaped clamping plates 5 can be pulled closer to each other, releasing the clamping connection between the arc-shaped clamping plates 5 and the annular groove 7. At this time, the cables are no longer pressed, and the cables can be adjusted. After completion, reset them again.

[0033] In addition, each layer of cables is separated by an intermediate bracket 2, and cables in the same layer are separated by an annular slot 7, which also helps with heat dissipation.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
