Abstract
The invention discloses a buffer, which is used for a transmission line to erect an iron tower or a tall building. The buffer is characterized in that a framework is installed on a winding drum of which the surface is welded with a guide helix; the framework is provided with a fixed pulley and a braking device; the braking device comprises a braking body and a braking part installed on the braking body by a hinge pin; the braking part is provided with a joystick; the framework comprises two stand columns and one cross bar, wherein the two stand columns are welded on the winding drum, and the one cross bar is arranged on the upper ends of the stand columns; and the guide helix is formed by welding the winding drum on a reinforcing steel bar along the spiral direction. When the iron tower is erected, one side of the iron tower is tied with a lifting steel wire rope, the other side of the iron tower is tied with a buffer steel wire rope, the buffer steel wire rope is wound on the winding drum, and then the buffer steel wire rope passes through the fixed pulley and the braking device. The releasing speed of the buffer steel wire rope can be controlled by the joystick. Because the winding drum is welded with the guide helix, the buffer steel wire rope successively slides along the guide helix on the winding drum to ensure that the hoisting operation is safely and stably carried out.
Description
Technical field
The invention belongs to transmission line of electricity technical field, the snubber of using while particularly lifting by crane steel tower or high constructure.
Background technology
When past transmission line construction lifting steel tower and high constructure, lift with wire rope in a side of steel tower by support (pole), opposite side is fastened buffer rope.After buffer rope is wrapped on wedge, its tail end is strained by two people or more people, in lifting process, discharges lentamente.Ensure like this steel tower in lifting process not reason lift wire rope and overexert and topple over.The shortcoming of this method is that labour intensity is large, and buffer rope extruding mutually on wedge, can not be released lentamente smoothly, is difficult to ensure the safety of lifting operation.
Summary of the invention
The problem that has potential safety hazard in order to solve transmission line construction lifting steel tower and high constructure operation, proposes following technical scheme.
A kind of snubber, its special character be its surface soldered have guiding spiral reel on installation frame, fixed pulley and brake gear are installed on framework, and this brake gear is made up of the brake member that brakes body and be arranged on brake body by bearing pin, and control stick is installed on brake member.
So-called framework can form by being welded on two root posts on reel and a cross bar of column upper end.So-called guiding spiral is that reinforcing bar is welded with on reel and is formed along the hand of spiral, its objective is and guides and ensure that buffer rope is wound on reel in turn, does not rub each other, pushes.
This snubber will be fixed on it in earth anchor or fixed buildings before using.When lifting steel tower, tie up to the wire rope that lifts of steel tower one side with winch traction, topple in order to prevent steel tower, opposite side at steel tower is fastened buffer rope, the free end of buffer rope is wound around and passes through fixed pulley later from reel, from brake gear, pass again, between brake body and brake member, pass.The direction of pull of buffer rope and the opposite direction that lifts wire rope.
Can control the gap between brake member and brake body by the control stick of brake gear, control the rate of release of buffer rope, and owing to being welded with guiding spiral on reel, buffer rope slides in turn along the guiding spiral on reel, ensure that lifting operation safety and steady carries out.

Detailed description of the invention
Embodiment
A snubber of using when transmission line of electricity stands up steel tower or high constructure, it be its surface soldered have guiding spiral 2 reel 3 on weld two root posts 4, at the top of column 4 welding beam 6.The common formation framework of reel 3 and two root posts 4 and crossbeam 6.Fixed pulley 5 is arranged on pulley yoke 7 by pulley spindle 12, and pulley yoke 7 is welded on crossbeam 6.Separately on crossbeam 6, be also welded with the brake mount 8 that is flute profile, brake member 10 is installed on brake mount 8 by bearing pin 11, and control stick 9 is installed on brake member 10.
Before using, with the fixing hole 1 on steel wire penetrating volume 3, this snubber is tied up in earth anchor or fixed buildings.When lifting steel tower, what tie up to steel tower one side with winch traction lifts wire rope (not drawing in figure), topple in order to prevent steel tower, fasten buffer rope (not drawing in figure) at the opposite side of steel tower, the free end of buffer rope passes through fixed pulley 5 after reel 3 is wound around, then passes between brake member 10 and brake mount 8.Lift wire rope in winch traction and stand up in steel tower process, by controlling control stick 9, slowly the free end of buffer release wire rope, ensures that steel tower safety and steady stands up like this.Brake member 10 is cam face.When control stick 9 is in the time that bearing pin 11 rotates counterclockwise, unclamp buffer rope, when control stick 9 is locked buffer rope in the time that bearing pin 11 clockwise rotates.
Claims (1)
1. a snubber, it is characterized in that its surface soldered have guiding spiral reel on installation frame, fixed pulley and brake gear are installed on framework, and this brake gear is made up of the brake member that brakes body and be arranged on brake body by bearing pin, and control stick is installed on brake member.
