Description

Technical Field

[0001] This utility model relates to the field of power construction, and in particular to a cable guide device for laying cables on a cable support. Background Technology

[0002] Cable support installation is a type of cable laying, which involves laying cables on cable supports in cable trenches. The laying process mainly uses a traction device to pull the cable along the laying path to the designated position. Since cable supports are set at intervals, pulling the cable directly on the cable supports can easily damage the outer protective layer of the cable. Therefore, currently, the main method is to straighten the cable in the cable trench and then lift the cable onto the cable supports. This laying method is time-consuming and labor-intensive, increasing labor costs.

[0003] Existing technologies include traction by setting guide pulleys on cable supports. Although this can effectively prevent damage to the outer protective layer of the cable, after traction, the cable needs to be moved from the guide pulleys and then neatly arranged, which still presents the problems of cumbersome operation, time and labor.

[0004] Based on this, this application provides a cable guiding device for laying cables on cable supports, which can pull cables on cable supports and automatically lower them onto the cable supports, while also facilitating the adjustment of the position of the guide rollers, thus solving the problem of needing to manually lay cables. Utility Model Content

[0005] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model provides a cable guiding device for laying cables on cable supports, which can pull cables on cable supports and automatically lower them onto the cable supports, while also facilitating the adjustment of the position of the guide rollers, thus solving the problem of needing to manually lay cables.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A cable guiding device for laying cables on cable supports is provided. It is installed on the inner wall of a cable trench between cable supports and includes a movable seat, a connecting rod, a lever, a linear actuator, a guide pulley, and a movable seat adjustment assembly. The lever has a connecting rod hinged to its middle section, and the other end of the connecting rod is hinged to an ear plate on the movable seat. The guide pulley is fixedly installed at one end of the lever, and the other end of the lever is hinged to the push rod of the linear actuator. The linear actuator is fixedly installed on the movable seat and controls whether the guide pulley is exposed or not on the upper surface of the cable support. The movable seat is movably installed on the movable seat adjustment assembly, and the cable laying position on the cable support is adjusted by adjusting the position of the movable seat on the movable seat adjustment assembly. The movable seat adjustment assembly is fixedly installed inside the cable trench.

[0008] In some alternative embodiments, the movable seat adjustment assembly is a manually adjustable bracket, including a mounting panel and a cantilevered square steel welded to the mounting panel. The movable seat is provided with a square guide hole and is slidably mounted on the square steel and fixed by a set bolt.

[0009] In some optional embodiments, the movable seat adjustment assembly is an automatic adjustment device, which includes a fixed frame, a lead screw, a guide rod, and a drive device. The lead screw is rotatably installed in the fixed frame, and the guide rod is fixedly installed in the fixed frame parallel to the lead screw. The movable seat is provided with a screw hole that is threadedly connected to the lead screw and a guide hole that is slidably connected to the guide rod. The movable seat is movably disposed on the guide rod and the lead screw, and the drive device is used to drive the lead screw to move the movable seat.

[0010] In some alternative embodiments, a mounting bracket is also included, on which the automatic adjustment device is fixedly mounted, and the mounting bracket is fixed to the cable trench by expansion bolts.

[0011] In some alternative implementations, the linear actuator is an electric push rod or a cylinder.

[0012] In some alternative implementations, the drive device is an adjustment handwheel or a servo motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets up multiple guiding devices between cables. These guiding devices can drive guide pulleys through a linear actuator to protrude from the upper surface between the cables. At this time, the guide pulleys of the multiple guiding devices form rolling friction with the cables, which facilitates the traction of the cables. After the traction is completed, the guide pulleys are controlled to be lowered. The cable is placed during the lowering process. There is no need to place the cable manually, which saves time and effort.

[0015] 2. The guide pulley is mounted on the movable seat, which is mounted on the movable seat adjustment assembly. The position of the guide pulley can be adjusted, which in turn can adjust the laying position of the cable on the cable bracket, realizing the orderly laying of the cable without the need for manual cable arrangement and improving the cable laying efficiency.

The movable seat 2 has a threaded hole for threaded connection with the lead screw 1b.2 and a guide hole for slidable connection with the guide rod 1b.3. The movable seat 2 is movably mounted on the guide rod and the lead screw. The drive device 1b.4 is used to drive the lead screw 1b.2 to move the movable seat 2. In this embodiment, the drive device 1b.4 is an adjusting handwheel or a servo motor, preferably a servo motor. This embodiment utilizes the drive device to drive the movable seat to move along the lead screw, facilitating automatic adjustment of the guide pulley position.

[0035] In this embodiment, the automatic adjustment device 1b is installed using a mounting bracket 7. Specifically, the automatic adjustment device is fixedly installed on the mounting bracket, which is then fixed to the cable trench using expansion bolts.
