For example, a lifting eye or hook may be provided at the cable tray of the reference section 10 and/or the extension section 20, which can be driven by a crane or the like, to bring the cable tray to different heights. Of course, other types of height adjustment elements are also possible, as long as they fulfill the corresponding function.

The utility model discloses an realize among the cable laying device: when laying cables, the extension 20 can be extended to different extents depending on the required cable length, and the height of the reference section 10 or the extension 20 can be adjusted accordingly depending on the required laying height.

In the cable laying device 100 disclosed in the present invention, the extension section 20 can be extended from the reference section 10 in various ways, for example, in a telescopic structure or a swivel-folding type connection manner. In particular, referring first to fig. 1 to 4, which show an embodiment of the invention, the connection between the base section 10 and the extension section 20 is realized in a manner rotatable relative to each other at the longitudinal ends by means of their respective cable brackets. That is, the two cable trays of the reference section 10 and the extension section 20 are connected to each other to be able to rotate in any direction in space according to the laying work requirements, and any suitable technical means in the prior art may be used to achieve this connection effect, for example, a ball joint mechanism or a universal joint type connection mechanism or other connection means may be provided at the longitudinal ends of the cable trays of the reference section 10 and the extension section 20, as long as they can achieve the corresponding functions.

Optionally, in some embodiments of the present invention, the two cable trays 1, 2 of the reference section 10 and the elongated section 20 are connected at their longitudinal ends in a pivoting connection, so that the reference section 10 and the elongated section 20 can be rotated 360 degrees relative to each other in a vertical plane perpendicular to the longitudinal axis of the cable tray, can be fully unfolded in one plane, can also be extended at an angle to each other, and can even be stacked together in full coincidence with each other (as shown in fig. 3 to 4).

Fig. 3 to 4 exemplarily show a state of pivotal connection between the cable tray in the reference segment 10 and the extension segment 20. Fig. 3 shows a state in which the cable trays are placed on top of each other. Fig. 4 shows the cable trays in the cable laying device 100 in different angles of rotation relative to one another, wherein the middle cable tray can be lifted by the lifting device. In order to support the cable tray in the air more stably, a support device may be used to support the suspended cable tray in some use occasions.

Referring additionally to fig. 5-6, another connection between the reference segment 10 and the elongate segment 20 is shown. In particular, the cable tray of the extension 20 is telescopically connected with the cable tray of the reference section 10, i.e. the cable tray of the extension 20 as a whole is telescopically movable with respect to the cable tray of the reference section 10. In this case, in order to increase the compatibility of this connection with respect to the laying requirements, both the reference section 10 and the extension section 20 can be height-adjusted. In particular, for example, a slide rail can be provided in the cable carriage of the reference section 10 for the cable carriage of the extension section 20, so that the cable carriage of the extension section 20 can be telescoped longitudinally along the slide rail relative to the reference section 10. For another example, in order to achieve the height adjustment function of both the reference segment 10 and the elongated segment 20, the cable laying device 100 may be configured to include a lifting leg 30 respectively disposed at the bottom of the reference segment 10 and the elongated segment 20, and the lifting leg 30 may move the reference segment 10 and the elongated segment 20 up and down.

Preferably, the height of the moving mechanism 40 is set higher than the lifting legs 30 without extension (as shown in fig. 6). In this case, it can be achieved that, when laying the cable, the extension section 20 can be first extended from the reference section 10 with the movement mechanism supporting the reference section 10, and after being extended to a specified length, the lifting legs 30 provided at the bottom of the reference section 10 and the extension section 20, respectively, are adjusted to a desired height (as shown in fig. 5).

Alternatively, referring exemplarily to fig. 2, in the disclosed cable laying device 100, for an elongated section 20 containing two or more cable trays, the longitudinal ends of the cable trays 2 in the elongated section 20 can be rotatably connected to each other as described above, or the cable trays 2 in the elongated section 20 can be telescopically connected as described above. In order to facilitate stacking of a plurality of cable trays in the case of a rotatable connection between the cable trays 2 in the extension 20, the region of the rotatable connection of the cable tray to other cable trays, i.e. the connection 21, may be configured as follows: the two connecting portions 21 of the longitudinal ends of the cable tray extend in opposite directions perpendicular to their longitudinal axis (as shown in fig. 1 to 4). In particular, the connecting portions 21 may be configured to extend in opposite directions with respect to the cable tray 2, for example, the connecting portion 21 of one longitudinal end portion may be configured to extend in an arc upward with respect to the cable tray 2, and the connecting portion 21 of the other longitudinal end portion may be configured to extend in an arc downward with respect to the cable tray 2.

Optionally, in some embodiments of the present invention, the load-bearing part 22 may comprise a drag chain, wherein the cable is parcel-wise accommodated in the drag chain. Here, the tow chain is flexible, which can follow the bending of the cable trays 1, 2 while providing protection for the cables therein. In contrast, as shown in fig. 2, in some embodiments of the present invention, the carrier part 22 may be configured directly in the cable tray 1, 2, for example as a stop element provided in said cable tray 1, 2. Such a stop element is able to accommodate the laying of the cable and to maintain the laying position of the cable. For example, the spacing element comprises a longitudinal spacing portion 221 and/or a lateral spacing portion 222. Here, the longitudinal stopper portion 221 is configured to include at least one longitudinal stopper groove longitudinally provided in the cable tray 1, 2, in which a groove formed by the stopper groove accommodates the cable, and the lateral stopper portion 222 may be configured to include at least one lateral stopper rail laterally provided in the cable tray, in which the cable is stopped under the lateral stopper rail without protruding out of the range of the height direction of the cable tray 1, 2 due to a drag action. Furthermore, the stop element can also be designed, for example, as a stop post, a stop cover, etc. Of course, other limiting elements capable of achieving the same function also fall within the scope of the present invention.

Alternatively, as can be seen from fig. 1 to 4, in some embodiments of the present invention, the lateral outer sides of the cable trays 1, 2 may also be provided with one or more cable clamps 13, 23, e.g. longitudinally distributed retaining rails, which may be used to store cable splices.

Alternatively, as can be seen from fig. 1 to 4, the cable laying device 100 may further include a lifting portion 31 provided at the cable tray of the reference segment and/or the elongated segment for assisting the lifting movement of the cable tray. The lifting part 31 can exist at the cable tray in various forms depending on the shape and design of the cable tray. Here, the lifting part 31 may be configured to include two sets of lifting members respectively provided at both lateral sides of the cable tray. In the scope of the present invention, "lateral" refers to a direction perpendicular or approximately perpendicular to the direction of extension of the cables arranged in the cable tray, while correspondingly "longitudinal" refers to a direction coinciding or approximately coinciding with the direction of extension of the cables arranged in the cable tray 1. In the two sets of lifting elements, each set of the lifting elements includes at least one lifting hook or lifting eye for smoothly adjusting the height of the cable tray. Optionally, the lifting elements are distributed at both sides with respect to a middle axis of the cable tray. In other words, the lifting hooks or lifting elements in each set of lifting elements are arranged distributed in the longitudinal direction of the cable tray. Here, the "central axis" refers to the middle of the longitudinal direction of the cable tray. Some drive equipment, such as cranes and the like, are capable of lifting the cable tray by pulling on the hook or eye of the cable tray.

Optionally, the cable laying apparatus disclosed in the present invention may further include a cable connection mechanism connecting the cable of the reference section and the cable of the extension section at a longitudinal end, or connecting the longitudinal end of the cable of the reference section or the extension section with the electric device.
