Description

Technical Field

[0001] This utility model relates to the field of cable laying auxiliary technology, and in particular to a cable laying device. Background Technology

[0002] A cable laying machine is an auxiliary construction device specifically designed to support and release cable reels. Its core function is to allow heavy, large cable reels to rotate easily and smoothly, thereby safely and efficiently laying cables to designated locations. It is an indispensable tool in power engineering, communication networks, railway construction, construction sites, and other applications requiring long-distance cable laying.

[0003] Existing cable reeling devices generally include a cable tray, a main shaft, and rolling elements rotatably mounted on the main shaft. When the main shaft is installed between the cable trays, its length is usually fixed, and the length of the main shaft is adapted to the horizontal spacing between the cable trays. The main shaft and the cable tray are configured and installed in a one-to-one correspondence, resulting in poor adjustability of the main shaft during installation and use. At the same time, when the rolling elements guide the cable, a part of the cable comes into contact with a single rolling element, and the part of the cable is not easily circumferentially restrained. As a result, there is a risk that the part of the cable will detach from the rolling element, making cable reeling difficult. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a cable feeder to solve the problem that the length of the spindle is difficult to adjust, resulting in poor adjustability of the spindle during installation and use.

[0005] To achieve the above objectives, the basic solution of this utility model is as follows: a cable unloader, comprising a fixed bracket and a rolling element, wherein the fixed bracket includes:

[0006] Mounting rod, with rolling elements coaxially and rotatably mounted on the mounting rod;

[0007] A sleeve is fitted onto the end of the mounting rod. The overlap between the end of the mounting rod and the end of the sleeve is adjustable. The end of the mounting rod or the end of the sleeve is detachably connected to the cable tray.

[0008] The technical principle of this utility model is as follows: When installing the fixed bracket onto the cable tray, the sleeve is installed onto the end of the mounting rod. The overlap between the sleeve and the end of the mounting rod is adjusted according to the installation width of the cable tray to adjust the overall length of the mounting rod and the sleeve. When installing the ends of the mounting rod and the sleeve onto the cable tray, the end of the mounting rod and the inner wall of the sleeve can be kept in a sliding but not separated state, which facilitates the fitting of the end of the mounting rod or the end of the sleeve with the installation location of the cable tray. Therefore, the overall length of the mounting rod and the sleeve can be efficiently adjusted during installation, improving the installation efficiency of the fixed bracket, and also adapting to cable trays of different widths, thus improving the adaptability of the cable reel in use.

[0009] Furthermore, the sleeve and the mounting rod are coaxially arranged.

[0010] With the above settings, when the sleeve and mounting rod support the rolling element, the sleeve can be subjected to more uniform and stable force in the circumferential direction, thus achieving stable support for the rolling element.

[0011] Furthermore, the outer wall of the sleeve is provided with several strip-shaped holes that communicate with the sleeve, and the length direction of the strip-shaped holes is arranged along the axial direction of the sleeve;

[0012] The end of the mounting rod is provided with several insertion holes that can overlap with the strip hole.

[0013] With the above settings, after adjusting the overall length of the mounting rod and sleeve, align the strip hole with the insertion hole. At this point, the overlapping length of the mounting rod and sleeve can be locked through the strip hole and insertion hole, making it easy to fasten the mounting rod and sleeve.

[0014] Furthermore, it also includes several connecting plates, one end of which is provided with a first connecting hole for the installation rod or sleeve to pass through;

[0015] The other end of the connecting plate can be detachably connected to an adjacent mounting rod or sleeve, with the two adjacent rolling elements facing each other.

[0016] With the above configuration, the connecting plate can connect two sets of fixed brackets and rolling elements, so that a limiting space is formed between the rolling elements to limit the cable. The rolling elements can support and guide the cable in a circumferential direction, making the cable transmission stable and convenient. The connecting plate can fully connect two sets of mounting rods or sleeves.

[0017] Furthermore, the connecting plate has a second connecting hole at one end away from the first connecting hole for the mounting rod or sleeve to pass through; or, the connecting plate has a third connecting hole at the other end that can be detachably connected to the adjacent connecting plate.

[0018] With the above configuration, the connecting plate can be connected to adjacent mounting rods, sleeve mounting rods, or connecting plates, so that the connection and cooperation of the two sets of fixed brackets are stable, and the relative cooperation of the two sets of rolling elements is stable.

[0019] Furthermore, the diameters of the first connecting hole and the second connecting hole are the same, or the diameters of the first connecting hole and the third connecting hole are the same.

[0020] By setting the aperture, it is easier to process and set the first connecting hole and the second or third connecting hole on the connecting plate, and the holes on both ends of the connecting plate can be interchanged, making the connecting plate more convenient to use.

[0021] Furthermore, the middle part of the rolling element has an annular groove that is concave towards the axis, and both ends of the rolling element are frustum-shaped.

[0022] With the above settings, the annular groove and frustum-shaped parts of the rolling element can fully limit the guide cable, making the cable laying more stable. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the cable reel in the axial direction of an embodiment of the present invention.

[0024] In the above figures: fixed bracket 10, mounting rod 101, sleeve 102, strip hole 112, rolling element 20, connecting plate 30, first connecting hole 301, and third connecting hole 302. Detailed Implementation

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] This embodiment is basically as follows: Figure 1 As shown in the figure, this utility model embodiment proposes a cable release device, including a fixed bracket 10, a rolling element 20, and two sets of connecting plates 30. The fixed bracket 10 includes a mounting rod 101 and two sleeves 102. The rolling element 20 is coaxially and rotatably mounted on the mounting rod 101. The two sleeves 102 are respectively sleeved on both ends of the mounting rod 101. The sleeves 102 and the mounting rod 101 are coaxially arranged, and the overlap between the end of the mounting rod 101 and the end of the sleeve 102 is adjustable. At the same time, the end of the sleeve 102 is detachably connected to the cable tray.

[0027] At the same time, such as Figure 1 As shown, the outer wall of the sleeve 102 is provided with two strip holes 112 that communicate with the sleeve 102. The length direction of the two strip holes 112 is arranged along the axial direction of the sleeve 102, and the two strip holes 112 are arranged sequentially along the axial direction of the sleeve 102.

[0028] like Figure 1 As shown, the end of the mounting rod 101 is provided with three insertion holes that can coincide with the strip hole 112, and pins can be inserted into the insertion holes and the strip hole 112.

[0029] like Figure 1 As shown, one end of the connecting plate 30 is provided with a first connecting hole 301 for the mounting rod 101 to pass through, and the other end of the connecting plate 30 is provided with a third connecting hole 302 that can be detachably connected to the adjacent connecting plate 30; the diameters of the first connecting hole 301 and the third connecting hole 302 are the same.

[0030] like Figure 1 As shown, the middle part of the rolling element 20 is a concave annular groove towards the axis, and the two ends of the rolling element 20 are frustum-shaped; two adjacent rolling elements 20 face each other, and a guide gap is formed between the two rolling elements 20 for the cable to pass through.

[0031] In this embodiment, when the cable laying device is in use and there are no objects interfering with the cable laying process, and the laying is expected to be relatively smooth, a single set of fixed brackets 10 and rolling elements 20 can be selected for use as needed. Simply install the single set of fixed brackets 10 between the cable trays, and install the two sleeves 102 onto both ends of the mounting rod 101. At this time, adjust the overlap between the sleeves 102 and the ends of the mounting rod 101 according to the installation width of the cable tray to adjust the overall length of the mounting rod 101 and the two sleeves 102. Then, align the strip hole 112 with the insertion hole, ensuring the overlap is within the specified range. Inserting a pin into the slot 112 and the insertion hole will initially lock the installation of the mounting rod 101 and the two sleeves 102. When the end of the sleeve 102 is installed between the cable trays, the cooperation between the slot 112 and the pin allows the mounting rod 101 and the sleeve 102 to remain in a sliding but not separated state, which facilitates the fitting of the end of the sleeve 102 to the installation position of the cable tray. Therefore, the overall length of the mounting rod 101 and the two sleeves 102 can be efficiently adjusted during installation, improving the installation efficiency of the sleeve 102. It also adapts to cable trays of different widths, improving the adaptability of the cable reel in use.

[0032] When the cable tension is high or there is a lot of debris in the surrounding area during unwinding, such as Figure 1 The method shown employs two sets of fixed brackets 10 and rolling elements 20. Before installing the fixed brackets 10 and rolling elements 20 between the cable trays, four sets of connecting plates 30 are first installed on both ends of the two sets of mounting rods 101. Then, the third connecting hole 302 of the connecting plate 30 is aligned with the third connecting hole 302 on the adjacent connecting plate 30 and fixed with bolts and nuts, so that the two sets of rolling elements 20 are aligned and the annular groove between the two rolling elements 20 forms a guide gap for the cable to pass through. Then, the end of the sleeve 102 is connected to the installation point of the cable tray for installation.

[0033] When laying the cable, the cable is attached to the annular groove of the rolling element 20 or the guide gap between the two rolling elements 20. The rolling element 20 can support and guide the cable. The two rolling elements 20 at the guide gap can stably limit the circumferential movement of the cable, making the cable transmission stable and convenient.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
