Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular, to a laying device for large-diameter buried cables. Background Art

[0002] In domestic new energy power generation, as well as in industries such as electricity and communication, large-diameter buried high- and low-voltage cables are a common method. Ensuring the quality, safety, and stability of cable laying is crucial. However, in the process of traditional buried cable laying, directly dragging the cable in the cable trench by manpower or equipment often encounters the following problems due to the lack of effective protection and positioning measures: The pulling force during cable traction may cause cable damage; the cable fails to accurately maintain its designed position, making it difficult to locate during later maintenance; at the same time, the dragging of the cable may also damage the underlying cushion sand layer, affecting the insulation performance and service life of the cable. Therefore, it is particularly necessary to develop a new tool that can effectively protect the cable from physical damage, ensure accurate cable positioning, and avoid damage to the laying environment.

It should be understood that the objects used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described.

[0038] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0039] The following will describe in detail some embodiments of the present utility model in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0040] To solve the technical problems existing in the prior art, an embodiment of the present utility model provides a device for laying large-diameter underground cables, including:

[0041] A support frame, the support frame includes at least two support frames;

[0042] Through holes are provided on the at least two support frames, and the through holes on the at least two support frames are communicated with each other to form a channel for placing the cable;

[0043] A plurality of rollers are provided at the edges of the through holes.

[0044] It should be noted that this device is used to assist in laying the cable in the pre-buried gully that has been dug. The support frame in this device can support the cable to be laid, avoiding it from directly contacting the ground, thereby avoiding damage to the sand cushion layer under the pre-buried gully during the dragging process of the cable, etc., and improving the insulation performance and service life of the cable.

[0045] It should be noted that the rollers provided at the edges of the through holes can reduce the friction between the cable and the support frame, reducing the risk of cable damage.

[0046] In some feasible embodiments, based on the foregoing solution, the at least two support frames include a first support frame and a second support frame connected to each other;

[0047] The first support frame is arranged on the front side of the support frame, and the second support frame is arranged on the rear side of the support frame.

[0048] It can be understood that the function of the support frame is to support the cable, and its number can be increased on the basis of two according to actual needs; when there are more than two support frames, the through holes of the support frame at the frontmost of the support frame are sequentially communicated with the through holes of the support frame in the middle and the through holes of the support frame at the rearmost to form a channel for placing the cable.

[0049] Exemplarily, referring to Figure 1 , a front view of a laying device for a large-diameter underground cable according to an embodiment of the present invention is shown.

[0050] Referring to Figure 2 , a top view of a laying device for a large-diameter underground cable according to an embodiment of the present invention is shown.

[0051] As Figure 1 and Figure 2 shown, the device includes a support frame 1, the overall structure of the support frame 1 is a rectangular frame, the front end face of the support frame 1 is the first support frame 2, and the rear end face is the second support frame 3; the overall structures of the first support frame 2 and the second support frame 3 are rectangular frames; the middle of the rectangular-frame-shaped first support frame 2 and the second support frame 3 is hollow, that is, a through hole, and the through holes of the first support frame 2 and the second support frame 3 are communicated to form a channel for placing the cable; rollers are respectively arranged on the four sides of the first support frame 2 and the second support frame 3.

[0052] It should be noted that the overall structure of the support frame 1 is not limited to a rectangular frame; it can also be a triangular frame, a pentagonal frame, etc.; when the overall structure of the support frame 1 is a frame of other shapes, the structure of the support frame will also change accordingly; for example, when the support frame 1 is a triangular frame, the overall structure of the support frame is triangular, and when the support frame 1 is a pentagonal frame, the overall structure of the support frame is pentagonal, that is, the shape of the support frame is the cross-sectional shape of the support frame.

[0053] In some feasible embodiments, based on the foregoing solution, the support frame includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod;

[0054] The first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod are sequentially connected, and the fourth connecting rod is further connected to the first connecting rod.

[0055] Exemplarily, taking the first support frame 2 as an example, as Figure 1 shown, the first support frame 2 includes a first connecting rod 21, a second connecting rod 22, a third connecting rod 23, and a fourth connecting rod 24.

[0056] Among them, the first connecting rod 21, the second connecting rod 22, the third connecting rod 23 and the fourth connecting rod 24 are connected in sequence, and the fourth connecting rod 24 is then connected to the first connecting rod 21, finally enclosing a rectangular frame to form the first support frame 2.

[0057] It can be understood that the middle of the enclosed first support frame 2 is hollow, that is, a through hole for the cable to pass through is formed; when multiple support frames are arranged in sequence, the through holes of the multiple support frames form a channel for the cable to pass through.

[0058] In some feasible embodiments, based on the foregoing solution, the multiple rollers include: a first roller, a second roller, a third roller and a fourth roller;

[0059] The first roller is movably arranged on the first connecting rod;

[0060] The second roller is movably arranged on the second connecting rod;

[0061] The third roller is movably arranged on the third connecting rod;

[0062] The fourth roller is movably arranged on the fourth connecting rod.

[0063] Exemplarily, as Figure 1 and Figure 2 shown, the first roller 4 is installed on the first connecting rod 21, the second roller 5 is installed on the second connecting rod 22, the third roller 6 is installed on the first connecting rod 23, and the fourth roller 7 is installed on the first connecting rod 24; the first roller 4, the second roller 5, the third roller 6 and the fourth roller 7 can roll on the first connecting rod 21, the second connecting rod 22, the first connecting rod 23 and the first connecting rod 24 respectively, thereby reducing the friction of the cable when passing through the support frame, and the first roller, the second roller, the third roller and the fourth roller also correspondingly wrap the cable, reducing the risk of the cable being damaged by the outside.

[0064] In some feasible embodiments, based on the foregoing solution, the third connecting rod is arranged on the opposite side of the first connecting rod;

[0065] An opening and closing structure is arranged at the middle part of the first connecting rod, so that the first connecting rod can be disconnected or closed from the middle part;

[0066] An opening and closing structure is arranged at the middle part of the third connecting rod, so that the third connecting rod can be disconnected or closed from the middle part.

[0067] In some feasible embodiments, based on the foregoing solution, the first roller includes a first sub-roller and a second sub-roller, and the first roller can be separated into the first sub-roller and the second sub-roller following the disconnection of the first connecting rod.

[0068] The third roller includes a third sub-roller and a fourth sub-roller, and the third roller can be separated into the third sub-roller and the fourth sub-roller following the disconnection of the third connecting rod.

[0069] It can be understood that the opening and closing structure can be an opening and closing bridge structure, that is, the first connecting rod or the third connecting rod can be disconnected from the middle into two parts like an opening and closing bridge, or can be closed into a whole.

[0070] It can be understood that setting the first connecting rod and the third connecting rod as structures that can be disconnected and closed is for facilitating the placement of the cable in the channel and for facilitating the removal of the cable after the cable laying is completed.

[0071] For example, when laying a cable, the first connecting rod is opened, the first roller is divided into two from the middle, after the cable is placed in the channel, the first connecting rod is then closed, and the first sub-roller and the second sub-roller are combined into the first roller.

[0072] After the cable laying is completed, the third connecting rod is opened, the third roller is divided into two, after the cable is removed from the channel, the third connecting rod is then closed, and the third sub-roller and the fourth sub-roller are combined into the third roller.

[0073] In some feasible embodiments, based on the foregoing solution, spiral telescopic support arms are horizontally arranged on the left and right sides of the support frame respectively.

[0074] It can be understood that the spiral telescopic support arm can be telescoped, thereby changing its own length.

[0075] Exemplarily, as Figure 1 and Figure 2 shown, two spiral telescopic support arms 8 are respectively arranged on the left and right sides of the support frame 1, and by adjusting the lengths of the spiral telescopic support arms 8, the whole device can be adapted to pre-buried trenches of different widths.

[0076] In some feasible embodiments, based on the foregoing solution, support feet are arranged at the ends of the spiral telescopic support arms.

[0077] Exemplarily, as Figure 1 and Figure 2 shown, support feet 9 are arranged at the ends of the spiral telescopic support arms 8 to facilitate fixing the whole device in the pre-buried trench.

[0078] In some feasible embodiments, based on the foregoing solution, the support frame is made of high-strength materials.

[0079] It can be understood that the support frame made of high-strength materials has sufficient stability and load-bearing capacity to withstand the tension and weight during cable laying.

[0080] In some feasible embodiments, based on the foregoing solution, the roller is made of a high-strength polymer.

[0081] It can be understood that the high-strength polymer has excellent properties and is very suitable for being used as the roller in the embodiments of the present utility model.

[0082] After considering the specification and practicing the disclosed embodiments herein, those skilled in the art will readily conceive of other embodiments of the present utility model. The present utility model is intended to cover any variations, uses, or adaptations of the present utility model, which follow the general principles of the present utility model and include known common knowledge or conventional technical means in the technical field not disclosed by the present utility model.
