Description

Technical Field

[0001] The utility model relates to a cable laying auxiliary tool for a cable well steel pipe, in particular to a cable well steel pipe transmission guide wheel. Background Art

[0002] During the laying process of the cable well, the cables are often not laid in a straight line and need to turn to change direction. In addition, since there are protective steel pipes on both sides of the cable well, the steel pipe heads can easily scratch the cables when the cables pass through the protective steel pipes and the friction is large. At the same time, due to the cable's own gravity, the cables can easily sag and come into contact with the mouth of the protective steel pipe, causing the cables to directly rub against the mouth of the protective steel pipe in the cable well and cut the cables.

[0005] Preferably, the upper clamping plate and the lower clamping plate are both in the shape of arc-shaped sheets that match the side walls of the steel pipe.

[0006] Preferably, the end of the lower clamping plate is configured as a rounded transition.

[0007] A gasket is provided at the end of the locking rod opposite to the lower clamping plate.

[0008] The end of the locking rod close to the upper clamping plate is provided with a ring for facilitating the rotation of the locking rod.

[0016] like Figure 1-5 As shown, a cable well steel pipe transmission guide wheel includes a U-shaped body 1, and the U-shaped body 1 includes a top plate 101 in contact with the steel pipe 6 mouth and an upper clamping plate 102 and a lower clamping plate 103 extending to the inner and outer sides of the edge of the steel pipe mouth at the upper and lower ends of the top plate respectively, and opposite to each other, and a locking rod 2 with a thread left near the upper clamping plate is installed through the upper clamping plate, and the locking rod is rotated to make the lower clamping plate relatively close to the inner wall of the steel pipe mouth and clamped on the side wall of the steel pipe mouth, and side plates 3 are extended toward the outside of the steel pipe mouth on the left and right sides of the top plate, and a rotating shaft 4 is provided between the two side plates, and a roller 5 for supporting the cable 7 is installed on the rotating shaft. When in use, the U-shaped body is inserted into the edge of the steel pipe mouth, the upper clamp and the lower clamp are respectively placed on the outer and inner sides of the steel pipe side wall, and the locking rod is rotated to make the lower clamp and the inner wall of the steel pipe mouth relatively close and tight. Through the cooperation of the locking rod and the lower clamp, the U-shaped body is fixed to the edge of the steel pipe mouth, and the installation is convenient and quick. At the same time, a roller and a cable contact support are set on the side of the top plate facing the outside of the steel pipe mouth. Under the support and guiding action of the roller, the cable can pass through the steel pipe mouth of the cable well smoothly, which effectively avoids the steel pipe mouth from scratching the cable, reduces the friction in cable transmission, and improves the transmission efficiency.

[0017] Because the side wall of the steel pipe is arc-shaped, the upper clamping plate 102 and the lower clamping plate 103 are both arc-shaped sheets that match the side wall of the steel pipe, which can increase the contact area between the lower clamping plate and the side wall of the steel pipe, thereby allowing the U-shaped body to be more stably fixed on the edge of the steel pipe mouth.

[0018] After the lower clamping plate extends into the inner side of the steel pipe, the cable passing through the steel pipe may touch the end of the lower clamping plate, causing the lower clamping plate to scratch the cable. Therefore, the end of the lower clamping plate 103 is set to a rounded transition to avoid scratching the cable.

[0019] The end of the locking rod 2 opposite to the lower clamping plate is provided with a gasket 201, which can increase the contact area with the side wall of the steel pipe, so that the locking rod can better cooperate with the lower clamping plate for fixed clamping, thereby increasing the clamping stability.

[0020] The end of the locking rod 2 close to the upper clamping plate is provided with a ring 202 for facilitating the rotation of the locking rod. The locking rod can be tightened by hand or by passing a rod tool through the ring to tighten the locking rod, which is easy to operate.

[0021] There are more than three U-shaped parts installed at the edge of the steel pipe mouth, and the lower clamping plates of each U-shaped part body are connected by a retractable scissor-fork structure. Arranging three or more U-shaped parts at the edge of the steel pipe mouth can provide more rollers to support and guide the cable, better avoid the steel pipe mouth from scratching the cable, and connect the lower clamping plates of each U-shaped part body to form a ring shape through the retractable scissor-fork structure, which is convenient for simultaneously putting multiple U-shaped parts on the edge of the steel pipe mouth. The retractable scissor-fork structure can also adjust the diameter of the ring shape to achieve free stretching, which can be adapted to various types of steel pipes and has strong versatility. The scissor-fork structure is composed of two or more forked rods. Through the hinged connection between the rods, the entire structure can be extended and retracted in one plane, and the ends of the rods at both ends of the scissor-fork structure are hinged to the lower clamping plate.
