Description

Technical Field

[0001] The utility model relates to the technical field of railway electrical accessory equipment, in particular to a cable layered fixing device. Background Art

[0002] During railway construction, especially during the construction of the four major railway electrical systems (communication, signal, power, and traction substation), a large number of cables need to be laid to ensure the safe operation of trains. However, due to various factors such as construction costs and current railway industry standards, the width of the railway interval cable trench is usually 200 - 300 mm, and the depth is usually 300 mm. After deducting the space occupied by railway line equipment and cable joints in the cable trench, the space available for cable laying and mutual isolation between cables in the cable trench is very limited. Therefore, for the convenience of construction and control of construction costs, in actual construction, construction units usually directly place various cables of different specifications in the cable trench. There is not only a lack of obvious identification signs on the cables, but also the cables are placed in a chaotic manner. In order to ensure the normal operation of the railway, the line maintenance unit can only carry out cable maintenance during the avoidance of train operation or the short maintenance time in the early morning. The above cable laying method greatly reduces the maintenance and repair efficiency of the cables.

[0003] At the same time, due to the excessive number of cables stacked in the cable trench, the cables will completely block the bottom of the cable trench, resulting in the inability to timely remove various foreign matters such as sewage, garbage, and sediment entering the cable trench, affecting the rapid search for cables, causing great difficulties in the subsequent cable maintenance. At the same time, the above-mentioned dirt has a certain damage to the protective layer on the surface of the cable, shortening the service life of the cable.

[0004] In the prior art, a layered clamp for placing cables by fixing on the side wall is proposed, which includes a fixing piece and a cable hook. A clamping portion extending outward to both sides is provided on the fixing piece, and a clamping groove cooperating with the clamping portion is provided on the cable hook. Since the clamping portion extends outward from the fixing piece body, more materials are wasted during stamping processing. In addition, the overall installation width is increased, resulting in an increase in the widths of both the fixing piece and the cable hook. Content of the Utility Model

[0005] (1) Technical Problem

[0006] The purpose of the utility model is to provide a cable layered fixing device to solve the problems in the prior art that the connection structure width between the fixing piece and the cable hook is relatively large and more forming materials are wasted.

[0007] (2) Technical Solution

[0008] To achieve the above purpose, the utility model provides the following technical solution:

[0009] A cable layer fixing device includes a fixing piece and at least one cable hook detachably connected to the fixing piece. The fixing piece includes a first connecting portion and a fixing portion. At least two first hook portions and at least two second hook portions are integrally stamped on both sides of the first connecting portion along its width direction. The ends of the first hook portions and the ends of the second hook portions are both located inside the edge of the connecting portion. The cable hook includes a second connecting portion and a cable receiving portion integrally formed with the second connecting portion for clamping the cable. The second connecting portion is provided with a first engaging groove for clamping the first hook portion and a second engaging groove for clamping the second hook portion. The second connecting portion is provided with a first sliding-in notch for guiding the first hook portion to slide into the first engaging groove and a second sliding-in notch for guiding the second hook portion to slide into the second engaging groove.

[0010] Preferably, the first hook portions and the second hook portions are arranged alternately along the height direction of the second connecting portion.

[0011] Preferably, the second connecting portion is provided with a first limiting block on one side of the opening direction of the first engaging groove and a second limiting block on one side of the opening direction of the second engaging groove.

[0012] Preferably, the first limiting block is provided with a first guiding surface inclined towards the first engaging groove, and the second limiting block is provided with a second guiding surface inclined towards the second engaging groove.

[0013] Preferably, the second connecting portion is provided with a reinforcing rib between the first limiting block and the second limiting block.

[0014] Preferably, the side surface of the second connecting portion is provided with a first through hole corresponding to the stopping position of the first hook portion and a second through hole corresponding to the stopping position of the second hook portion.

[0015] Preferably, the cable receiving portion includes at least one cable receiving groove arranged along its length direction. The cable receiving portion is provided with an arc-shaped elastic portion extending towards one side of the cable receiving groove, and the end of the arc-shaped elastic portion is provided with a bending elastic portion extending towards the inside of the cable receiving groove.

[0016] Preferably, the bottom of the cable receiving groove is provided with arc-shaped convex portions at intervals.

[0017] Preferably, a first rib plate is provided between the cable receiving portion and the second connecting portion, and a plurality of second rib plates arranged at intervals are provided between the cable receiving portion and the first rib plate.

[0018] Preferably, the cable accommodating part includes elastic arms extending outward from the second connecting part. The elastic arms and the second connecting part enclose a cable accommodating groove. An elastic airbag extending toward one side of the cable accommodating groove is provided at the end of the elastic arm; a support block is provided between the bottom of the elastic arm and the second connecting part.

[0019] (III) Beneficial effects

[0020] After the cable hook is installed by at least two first hook parts and two second hook parts which are integrally stamped and formed directly on the connecting part of the fixing piece and arranged on both sides in the width direction respectively, it is relatively stable;

[0021] At the same time, since the first hook part and the second hook part are directly stamped and formed from the first connecting part, the ends of the first hook part and the second hook part are both located inside the edge of the first connecting part, that is, they will not protrude outward. Therefore, only the width of the first connecting part needs to be determined before stamping, and no material waste will be caused;

[0022] The first engaging groove and the second engaging groove provided on the cable hook can facilitate the cable hook to be directly slid and inserted onto the first hook part and the second hook part to form a stable engaging limit;

[0023] And when the first hook part and the second hook part are inserted into the first engaging groove and the second engaging groove, they are guided by the first sliding-in notch and the second sliding-in notch opened at the corresponding positions. Thus, the two first hook parts and the two second hook parts on the corresponding side can all have a stop and support part, forming 4 limits, and improving the engaging stability;

[0024] After changing the matching structure, the waste of the stamping material of the fixing piece is less, and the width of the cable hook is also shortened, synchronously reducing the material waste. Description of the drawings

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] See Figures 1 - 10As shown in the figure, in an embodiment of the present utility model, a cable layer fixing device is proposed, which is used to be arranged at intervals in a cable trench to support, suspend and fix various cables in the trench. Specifically, it includes a fixing piece 1 and at least one cable hook 2 detachably connected to the fixing piece 1. The fixing piece 1 includes a first connecting portion 11 and a fixing portion 12. At least two first hook portions 13 and at least two second hook portions 14 are integrally stamped on both sides of the first connecting portion 11 along its width direction. During specific forming and processing, only the entire fixing piece 1 needs to be punched according to a preset width, and then the first hook portions 13 and the second hook portions 14 are directly stamped on its first connecting portion 11, without causing additional material waste. Thus, the ends of the first hook portions 13 and the ends of the second hook portions 14 are both located inside the edge of the first connecting portion 11, making the width of the entire second connecting portion 21 controllable and not extending outward. Specifically, after the first hook portions 13 and the second hook portions 14 are stamped, their cross-sections are curved and have a certain elastic deformation.

[0039] Meanwhile, the cable hook 2 includes a second connecting portion 21 and a cable receiving portion 22 integrally formed with the second connecting portion 21 and used for clamping the cable. The cable receiving portion 22 is used to limit and tightly clamp the cable to form a support, and the second connecting portion 21 quickly installs the entire cable hook 2 onto the first connecting portion 11 for assembly. A first engaging groove 23 for engaging with the first hook portion 13 and a second engaging groove 24 for engaging with the second hook portion 14 are provided on the second connecting portion 21. At the same time, a first sliding-in notch 25 for guiding the first hook portion 13 to slide into the first engaging groove 23 and a second sliding-in notch 26 for guiding the second hook portion 14 to slide into the second engaging groove 24 are provided on the second connecting portion 21; after the first hook portion 13 and the second hook portion 14 are respectively guided into the first engaging groove 23 and the second engaging groove 24 through the first sliding-in notch 25 and the second sliding-in notch 26 to form relative sliding, the entire cable hook 2 is fully carried on the first hook portion 13 and the second hook portion 14 to form stable limitation; that is, the first hook portion 13 and the second hook portion 14 must enter and exit the first engaging groove 23 and the second engaging groove 24 through the first sliding-in notch 25 and the second sliding-in notch 26, and the cable hook 2 will not separate under the load-bearing state after hanging the cable, and the more it bears the weight, the more stable it is.

[0040] Meanwhile, a load-bearing stop structure for individually limiting each of the first hook portions 13 and the second hook portions 14 is formed at the positions where the first sliding-in notch 25 and the second sliding-in notch 26 are provided, realizing simultaneous load-bearing and limitation at 4 positions, and further improving the connection stability.

[0041] To further ensure the connection stability and prevent easy loosening, the first hooking portion 13 and the second hooking portion 14 are arranged staggeredly along the height direction of the second connecting portion 21, that is, the first hooking portion 13 and the second hooking portion 14 are not at the same height.

[0042] To cooperate with the elastic deformation effect of the first hooking portion 13 and the second hooking portion 14 after stamping and forming, and be limited after being correspondingly snapped into the first engaging groove 23 and the second engaging groove 24. Specifically, a first limiting block 27 is provided on the second connecting portion 21 on one side of the opening direction of the first engaging groove 23, and a second limiting block 28 is provided on one side of the opening direction of the second engaging groove 24. The first hooking portion 13 is limited by the first limiting block 27, and the second hooking portion 14 is limited by the second limiting block 28, restricting the possibility of directly disengaging from the opening directions away from the first engaging groove 23 and the second engaging groove 24.

[0043] At the same time, to ensure that when the first hooking portion 13 slides in the first engaging groove 23 and the second hooking portion 14 slides in the second engaging groove 24, they will not be hindered by the first limiting block 27 and the second limiting block 28. Therefore, a first guiding surface 29 inclined towards the first engaging groove 23 is provided on the first limiting block 27, and a second guiding surface 210 inclined towards the second engaging groove 24 is provided on the second limiting block 28. The first guiding surface 29 and the second guiding surface 210 are inclined surfaces to achieve avoidance and meet the sliding requirements. That is, the first hooking portion 13 and the second hooking portion 14 can only slide along the length direction of the first engaging groove 23 and the second engaging groove 24, and are limited to slide from the opening end, ensuring the stability of the installation connection.

[0044] Specifically, a reinforcing rib 211 is provided on the second connecting portion 21 between the first limiting block 27 and the second limiting block 28. The reinforcing ribs 211 are arranged horizontally and vertically to improve the overall bearing strength of the second connecting portion 21.

[0045] At the same time, a first through hole 212 corresponding to the stopping position of the first hooking portion 13 and a second through hole 213 corresponding to the stopping position of the second hooking portion 14 are provided on the side surface of the second connecting portion 21. Of course, the first through hole 212 and the second through hole 213 can also not be provided; but considering the need to pry the first hooking portion 13 and the second hooking portion 14 from the outside in the case of a relatively tight fit, the first through hole 212 and the second through hole 213 can be used for operation, facilitating auxiliary operation during disassembly.

[0046] Specifically, the cable is bound and installed through the cable accommodating part 22. During specific use, the cable diameter and quantity of the cable may vary. Therefore, at least one cable accommodating groove 214 is arranged along the length direction of the cable accommodating part 22. An arc-shaped elastic part 215 extending towards one side of the cable accommodating groove 214 is arranged on the cable accommodating part 22. A bent elastic part 216 extending towards the inside of the cable accommodating groove 214 is arranged at the end of the arc-shaped elastic part 215. Through the action of the arc-shaped elastic part 215 and the bent elastic part 216, the cable placed in the cable accommodating groove 214 can be tightly pressed and limited, preventing the cable from slipping out of the cable accommodating groove 214 and ensuring the binding effect.

[0047] And the number of cable accommodating grooves 214 to be arranged on one cable accommodating part 22 is the same as the number of cables to be bound, and the specific quantity is not limited.

[0048] Certainly, in some cases, it may be necessary to place two or more cables in one cable accommodating groove 214 and positioning is required. Therefore, arc-shaped protrusion parts 217 are arranged at intervals at the bottom of the cable accommodating groove 214, and the multi-cable small-interval positioning is initially realized by using the arc-shaped protrusion parts 217 arranged at intervals.

[0049] Meanwhile, in order to strengthen the bearing strength of the cable accommodating part 22, specifically, a first rib plate 218 is arranged between the cable accommodating part 22 and the second connecting part 21, and a plurality of second rib plates 219 arranged at intervals are arranged between the cable accommodating part 22 and the first rib plate 218. The bearing structure strength of the stress part is increased through the first rib plate 218 and the second rib plates 219 to meet the stability after cable hanging.

[0050] Another implementation manner can also be adopted for the cable accommodating part 22. Specifically, the cable accommodating part 22 includes an elastic arm 220 extending outward from the connecting part. The elastic arm 220 and the second connecting part 21 enclose to form the cable accommodating groove 214. An elastic airbag 221 extending towards one side of the cable accommodating groove 214 is arranged at the end of the elastic arm 220. Meanwhile, a support block 222 is arranged between the bottom of the elastic arm 220 and the second connecting part 21. The support block 222 is used to support the bottom of the elastic arm 220, mainly serving as the bearing structure after cable hanging. Meanwhile, the elastic arm 220 is used to wrap the cable placed in the cable accommodating groove 214, and the cable is tightly pressed and limited by the elastic airbag 221 to prevent the cable from slipping out.
