Description

Technical Field

[0001] The utility model relates to the technical field of optical cable laying, in particular to a trench optical cable laying frame for a transformer substation. Background Art

[0002] During the installation of optical cables in the trench of a substation, in order to ensure the quality of the optical cables, personnel need to be arranged to assist in pulling the cables after laying them for about 20 meters in the trench, especially at the corners of the trench. This means that the longer the distance the optical cables are laid, the more construction workers are required.

[0003] Publication No. CN210803833U discloses a substation trench optical cable laying rack, which can reduce the investment of construction personnel by at least half and improve its optical cable laying efficiency by more than one-third, making it suitable for widespread use. However, during the installation of optical cables, the path of the trench often adjusts due to various factors and is ultimately directed to the next substation. Therefore, the laying rack requires a certain angle adjustment function. This equipment needs to be assisted by other equipment or use multiple laying racks to continuously lay and adjust the angle, resulting in relatively low efficiency. To this end, we propose a substation trench optical cable laying rack. Utility Model Content

[0004] Aiming at the problems in the prior art, the utility model provides a trench optical cable laying frame for a transformer substation.

[0005] The technical solution adopted by the utility model to solve its technical problems is a substation trench cable laying rack, comprising a laying rack plate, wherein the top of the center of the laying rack plate is fixedly connected to a rotating base, the top surface of the rotating base is rotatably connected to a limited rotation shaft, a mounting bracket is assembled inside the limited rotation shaft, one side of the mounting bracket is fixedly connected to a first connecting rod, an end of the first connecting rod away from the mounting bracket is rotatably connected to a straight pulley, an end of the mounting bracket adjacent to the first connecting rod is fixedly connected to a second connecting rod, and the top surface of the end of the second connecting rod away from the mounting bracket is rotatably connected to a curved pulley;

[0006] The bottom end of the laying rack is fixedly connected with a plurality of expansion plug-ins, and the two end surfaces of the laying rack are rotatably connected with installation knobs. A mounting base is provided under the laying rack, and a plurality of expansion slots that match the expansion plug-ins are provided at the four corners of the top surface of the mounting base, and two threaded connection grooves that match the installation knobs are provided at both ends of the surface of the mounting base.

[0007] By adopting the above technical solution, four holes are first opened corresponding to the positions of the expansion tubes at the bottom end of the installation base plate, and then the installation base plate is aligned with the holes and inserted. Then, the expansion plug-in at the bottom end of the laying frame plate and the threaded extension end through which the installation knob passes are aligned with the threaded connection groove and the expansion slot on the surface of the installation base plate and inserted. The installation knob is rotated to fix the laying frame plate to the installation base plate, and the expansion plug-in is inserted into the expansion slot to complete the fixation of the installation base plate. Then, different pulleys are adjusted according to different channels. First, the fixing knob set on the side wall of the rotating base is unscrewed, and the friction block is driven to shrink and displace by rotating the transmission rod in the friction block to release the contact with the limit shaft. Then, the mounting frame is rotated to adjust the different pulleys to rotate to the side wall. The straight pulley and the curved pulley installed are respectively rotated by the first connecting rod and the second connecting rod to place the corresponding straight and curved pulleys in the channel and then lay the optical cable on the pulley.

[0008] Specifically, the side wall of the rotating base is rotatably connected to a fixed knob, one end of the fixed knob passing through the inner wall of the rotating base is fixedly connected to a transmission rod, and one end of the transmission rod away from the fixed knob is threadedly connected to a friction block.

[0009] By adopting the above technical solution, the rotation mode of the limit shaft is adjusted by rotating the fixed knob, thereby controlling different pulleys to rotate to the operating position.

[0010] Specifically, a limiting sliding block is provided at the bottom end of the friction block for limiting the sliding direction, and a friction pad for friction fixation is fixedly connected to the top end of the friction block.

[0011] By adopting the above technical solution, the movement direction of the friction block is limited by the limiting slider, so that it slides horizontally with the rotation of the transmission rod, and then the friction pad contacts the limiting shaft to complete the restriction of the shaft.

[0012] Specifically, an expansion pipe installed on the ground is fixed to the bottom end of the installation base plate below the expansion slot.

[0013] By adopting the above technical solution, the expansion plug is inserted into the expansion slot to support the expansion tube to complete the positioning function and thus complete the installation.

[0014] Specifically, the limiting rotating shaft can only rotate at an angle of 90 degrees on the surface of the rotating base.

[0015] By adopting the above technical solution, the corresponding pulley is adjusted to move to the side direction through the limit shaft that can only rotate at a vertical angle, thereby installing the optical cable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The technical solution of the present application is designed through the rotation base, the limiting shaft, the fixing knob, the transmission rod, the friction block, the mounting frame, the first connecting rod, the straight pulley, the second connecting rod and the curved pulley. First, four holes are opened corresponding to the position of the expansion tube at the bottom end of the mounting base plate. Then, the mounting base plate is aligned with the holes and inserted. Then, the expansion plug-in at the bottom end of the laying frame plate and the threaded extension end passed through by the mounting knob are aligned with the threaded connection groove and the expansion slot on the surface of the mounting base plate and inserted. The mounting knob is rotated to fix the laying frame plate to the mounting base plate, and the expansion plug-in is inserted into the expansion slot to complete the installation of the base plate. The plate is fixed, and then different pulleys are adjusted according to different channels. First, the fixed knob set on the side wall of the rotating base is unscrewed, and the friction block is driven to shrink and displace by rotating the transmission rod in the friction block to release the contact with the limit shaft. Then the mounting frame is rotated to adjust the different pulleys to rotate to the side wall, and the straight pulley and the curved pulley installed are respectively rotated by the first connecting rod and the second connecting rod. The corresponding straight and curved pulleys are placed in the channel and then the optical cable is laid on the pulley. It is convenient and applicable to most channels. The corresponding pulley can be freely adjusted according to the curvature of the channel, thereby speeding up the efficiency of laying the optical cable. BRIEF DESCRIPTION OF THE DRAWINGS
