Description

Technical Field

[0001] This utility model relates to the field of cable laying equipment technology, specifically to an auxiliary sliding shaft device for laying ladder-type cable trays. Background Technology

[0002] When laying cables in ladder-type cable trays, on-site construction generally uses manual labor or winches. Manual laying requires multiple people to work together. Due to the large gaps between the ladder sections of the cable tray, cable laying is cumbersome and requires multiple people to assist. It is not easy to slide according to the direction of cable pulling, resulting in low work efficiency. In addition, there is a lot of friction between the cable and the ladder section of the cable tray. During winch laying, the cable is subjected to greater stress, which can easily damage the outer insulation layer of the cable. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary sliding shaft device for cable laying in a ladder-type cable tray, which solves the problems of cable laying without a sliding shaft device, low construction efficiency, high friction during cable laying, and easy damage to the cable insulation layer.

[0004] The technical solution adopted in this utility model is as follows: A ladder-type cable tray cable laying auxiliary sliding shaft device includes two side movable frames, a central shaft, and rollers. The side movable frames are composed of a flange clamping piece and a socket frame. The flange clamping piece and the socket frame are fixed together by bolts. The rollers are sleeved on the central shaft and can rotate freely. The two socket frames are connected into one unit through the central shaft.

[0005] The flanged edge clamping piece and the socket bracket structure are both L-shaped structures, with a clamping post fixed at the horizontal end of the L. The vertical end of the flanged edge clamping piece is inserted into the vertical end of the socket bracket and fixed with bolts. The upper ends of the clamping posts of the two socket brackets are fixed to both ends of the central shaft.

[0006] The height of the movable side frame can be adjusted to 100mm, 150mm, or 200mm by adjusting the length of the flange clamp inserted into the socket. It is suitable for all standard ladder-type cable tray widths.

[0007] The flanged edge fitting, socket bracket, central shaft, and roller are all made of SC steel pipe. The diameter of the steel pipe of the socket bracket is larger than that of the steel pipe of the flanged edge fitting, the diameter of the steel pipe of the roller is larger than that of the steel pipe of the central shaft, and the diameter of the steel pipe of the central shaft is the same as that of the steel pipe of the socket bracket.

[0008] The distance between the two side movable frames is greater than the width of the ladder-type cable tray, and the length of the central axis is less than the width of the ladder-type cable tray.

[0009] This utility model has the following advantages: The materials used in this invention are commonly used construction materials, requiring small quantities and resulting in low cost.

[0010] This utility model is very simple to process and manufacture, and the quantity can be increased according to the construction needs of ladder-type cable trays; This utility model can be placed in the required position, is flexible and easy to use, and can be reused. This utility model is easy to operate, saves time and labor, eliminates the reduced efficiency and safety hazards caused by traditional manual assistance, increases the smoothness of construction and protects the insulation of cables.

Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1 , Figure 2 As shown, this utility model provides an auxiliary sliding shaft device for laying cables in a ladder-type cable tray, comprising two side movable frames, a central shaft 5, and a roller 4. The side movable frames are composed of a flange clamping piece 1 and a socket frame 2. The flange clamping piece 1 and the socket frame 3 are fixed together by bolts 2. The roller 4 is sleeved on the central shaft 5 and can rotate freely. The two socket frames 3 are connected into one unit through the central shaft 5.

[0013] like Figure 1 As shown, both the flange clamping piece 1 and the socket bracket 3 are L-shaped structures, and a clamping post is fixed at the horizontal end of the L. The vertical end of the flange clamping piece 1 is inserted into the vertical end of the socket bracket 3 and fixed by bolts 2. The upper ends of the clamping posts of the two socket brackets 3 are fixed to both ends of the central shaft 5.

[0014] The height of the movable side frame can be adjusted to 100mm, 150mm, or 200mm by adjusting the length of the flange clamp 1 inserted into the socket 3. It is suitable for all conventional ladder-type cable tray widths.

[0015] The flanged edge fitting 1, the socket bracket 3, the central shaft 5, and the roller 4 are all made of SC steel pipe. The diameter of the steel pipe of the socket bracket is larger than that of the steel pipe of the flanged edge fitting, the diameter of the steel pipe of the roller is larger than that of the steel pipe of the central shaft, and the diameter of the steel pipe of the central shaft is the same as that of the steel pipe of the socket bracket.

[0016] The distance between the two side movable frames is greater than the width of the ladder-type cable tray, and the length of the central axis is less than the width of the ladder-type cable tray.

[0017] like Figure 3 As shown, when the ladder-type cable tray 6 is too long, this utility model is used in conjunction with a cable laying winch. First, place the device of this utility model below the gap of the ladder-type cable tray 6, so that the roller 4 protrudes from the middle gap of the ladder-type cable tray 5. According to the height of the ladder-type cable tray 6, adjust the length of the flange clamp 1 inserted into the socket frame 3 so that the clamp post of the flange clamp is locked on the ladder-type cable tray 6 and tighten the bolt 2 to fix it. Then, use the winch to lay the cable and let the cable rest on the roller 4. The roller 4 can reduce the friction between the cable and the ladder-type cable tray 6, realize the auxiliary sliding function for various types of cables, thereby avoiding the problem of excessive friction during cable laying, which can easily cause damage to the cable insulation layer.

[0018] The components of this utility model are commonly used construction materials, requiring small quantities and having low costs. Auxiliary cables can be laid in the required locations, allowing for flexible movement, convenient use, and reusability. This saves labor costs, resulting in good economic benefits and significant promotional value.
