Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The application provides an auxiliary device for laying a cable bridge, which comprises a left vertical plate 1, a right vertical plate 3 and a mounting plate 10, wherein the left vertical plate 1 and the right vertical plate 3 are arranged in parallel, the mounting plate 10 is perpendicular to the left vertical plate 1 and the right vertical plate 3, and the mounting plate 10 is provided with a first mounting hole 17 connected with a cross arm 18; the middle parts of the left vertical plate 1 and the right vertical plate 3 are provided with a fixed shaft 8, and the fixed shaft 8 is rotatably connected with a pulley 5 for supporting a cable. The left vertical plate 1, the right vertical plate 3 and the mounting plate 10 are made of channel steel, so that the vertical plate has the advantages of being firm, durable and good in machining, and waste utilization is achieved. The left vertical plate 1, the right vertical plate 3 and the mounting plate 10 form a U-shaped structure, and then are matched with the pulleys 5 to form a U-shaped pulley.
When paying off, the force applied to the pulley 5 is mainly divided into two parts. Partly the pressure of the weight of the insulated wire itself against the pulley 5; the other part is the weight of the vehicle in a vertically downward direction of traction when pulling the wire. For this purpose, the pulley 5 of the invention is made with bearings of a ground displacement vehicle, which can fully comply with the pressure requirements.
Because the speed of the insulated conducting wire is too high when the insulated conducting wire is paid off, the insulated conducting wire can pop up from the pulley 5 and fall on the cross arm 18, and therefore, a locking device is arranged at the upper part of the fixed shaft 8 and is positioned between the left vertical plate 1 and the right vertical plate 3. The locking device is a screw rod, and two ends of the screw rod are fixedly connected with the left vertical plate 1 and the right vertical plate 3. In order to reduce the phenomenon of damaging the insulating layer caused by friction between the screw and the insulated conducting wire in the paying-off process, the sheath 2 is arranged outside the screw, and the distance between the axis of the screw and the axis of the fixed shaft 8 is larger than 10 mm.
Because the bolt in the first mounting hole can rotate in a small range in the paying-off process, the lower part of the mounting plate 10 is provided with a left auxiliary mounting plate 16 and a right auxiliary mounting plate 10, the left auxiliary mounting plate 16 is connected to the lower part of the left vertical plate 1, and the right auxiliary mounting plate 10 is connected to the lower part of the right vertical plate 3. And the left auxiliary mounting plate 16 is provided with a second mounting hole 15 for connecting the cross arm 18, the right auxiliary mounting plate 10 is provided with a third mounting hole 13 for connecting the cross arm 18, and bolts are mounted in the second mounting hole 15 and the third mounting hole 13.
In the paying-off process, the traction rope can be clamped in a gap between the pulley 5 and the left vertical plate 1 (the right vertical plate 3), therefore, a left baffle 4 is arranged on the left vertical plate 1 and positioned on the upper portion of the fixed shaft 8, and a right baffle 6 is arranged on the right vertical plate 3 and positioned on the upper portion of the fixed shaft 8. The left baffle 4 and the right baffle 6 are both arc-shaped plates, and openings of the arc-shaped plates are arranged downwards. When in paying off, the used traction rope is a steel wire rope with the diameter of 8mm, and the distance between the baffle and the pulley 5 is too large, so that the wire clamping can not be prevented; if the distance is too small, the pulley 5 is rubbed and the pulley 5 is not rotated flexibly, so that the damper is mounted 4mm above the pulley 5.
The left vertical plate 1 is provided with a left arc-shaped groove matched with the left end of the fixed shaft 8, one end, extending out of the left arc-shaped groove, of the fixed shaft 8 is provided with a left gasket 12 and a left bolt 11, the right vertical plate 3 is provided with a right arc-shaped groove matched with the right end of the fixed shaft 8, and one end, extending out of the right arc-shaped groove, of the fixed shaft 8 is provided with a right gasket 7 and a right bolt 9.
Although the present invention has been described in detail by referring to the drawings in connection with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
