Abstract
The invention discloses a rigid crossing support, in particular to a rigid crossing support and a crossing method for construction of overhead transmission lines. The rigid crossing support comprises a hanging basket for enabling operation staff to stand on, a pair of V-shaped outward-extending cleat-shaped structures is arranged on one end face of the hanging basket, two pulleys are arranged on a top beam of the hanging basket, and the hanging basket is installed at the top end of a lazy arm of a crane. The rigid crossing support and the crossing method for construction of overhead transmission lines have the advantage that by means of the hanging basket and the crane on the hanging basket, the crane can drive the hanging basket to finish cable crossing, meanwhile the V-shaped outward-extending cleat-shaped structures can prevent cables from dropping during cable crossing, the provided pulleys facilitate stable crossing of the cables, and the rigid crossing support is simple in structure, low in cost and good in safety and stability, requires no scaffold, is strong in maneuverability, convenient to operate and use and short in construction period, and ensures device safety and construction safety.
Description
Technical field
The present invention relates to a kind of rigid step-over support, particularly a kind of Overhead Transmission Line Construction rigid step-over support and crossing method of crossing over railroad bridge.
Background technology
The general construction plan that overhead transmission line is crossed over railroad bridge is to set up bamboo or steel pipe crossing frame in the railway both sides, to guide rope and throw railroad high voltage wire, laying the insulation net then constructs, there is drawback and the hidden danger of all many-sides in employed crossing frame in the existing leap construction, the frame overall volume is huge, process efficiency is lower, expense cost height, time cost height, economic benefit are not outstanding, also have the problem of security and stability difference; For example: after 7.23 warm river in Zhejiang Province line high-speed railway accidents took place in 2011, railway interests more became strict to the safety measure examination of crossing over the railway air line construction.
Summary of the invention
The present invention relates to a kind of simple in structure, cost is low, safety and firmness is good, the Overhead Transmission Line Construction that can guarantee device security and construction safety is with rigid step-over support and crossing method.
In order to solve the problems of the technologies described above, Overhead Transmission Line Construction of the present invention rigid step-over support, comprise one for the operating personnel's that stand hanging basket, one of them end face of hanging basket is provided with a pair of overhanging goat's horn that is in the shape of the letter V, two pulleys are set on the top cross-bar of hanging basket, and hanging basket is installed in the arm top of crane.
Described hanging basket is provided with the reinforcing platform of standing for operating personnel.
A kind of Overhead Transmission Line Construction crossing method of rigid step-over support may further comprise the steps:
(1) two cranes that make the arm top that hanging basket is installed are parked in the both sides of railroad bridge, and two operating personnel hand a guiding rope respectively and stand in two hanging baskets;
(2) arm with two cranes rises to the railroad bridge top synchronously, and two operating personnel throw two guiding ropes to railroad bridge respectively, and the middle staff of railroad bridge that is positioned at of wait guides the rope butt joint with two;
(3) two cranes progressively rotate to the position parallel with railroad bridge also will guide the rope tension;
(4) two crane rotations are to the position parallel with railroad bridge, and guiding rope pulling traction rope is by railroad bridge, and the steel wire rope that will be connected the suspension arm of crane front end simultaneously is separately fixed at ground earth anchor place;
(5) pull rope pulling cable is by railroad bridge, complete operation process.
The present invention has the following advantages:
Because the hanging basket that arranges and the crane that is used for installing hanging basket, can drive hanging basket by crane and finish the cable leap, the overhanging goat's horn that is in the shape of the letter V of She Zhiing can prevent coming off of cable in cable leap process simultaneously, the pulley that arranges is conducive to the steady leap of cable, and it is simple in structure, cost is low, safety and firmness is good, no longer needs to overlap scaffold, mobility strong, operation is used also very convenient, short construction period, and guaranteed device security and construction safety.

Embodiment
Below in conjunction with the drawings and specific embodiments, Overhead Transmission Line Construction of the present invention is described in further detail with rigid step-over support and crossing method.
As shown in the figure, Overhead Transmission Line Construction of the present invention rigid step-over support, comprise one for the operating personnel's 5 that stand hanging basket 1, one of them end face of hanging basket 1 is provided with a pair of overhanging goat's horn 2 that is in the shape of the letter V, two pulleys 3 are set on the top cross-bar of hanging basket 1, hanging basket 1 is installed in the arm top of crane 4, and hanging basket 1 is provided with the reinforcing platform of standing for operating personnel.
Further one of them pulley is arranged on the top for the crossbeam that overhanging goat's horn 2 is installed, the another one pulley is installed in parallel in for the crossbeam top that overhanging goat's horn 2 offsides are installed, two pulleys are installed in the middle part of crossbeam simultaneously, and the balance of hanging basket is good thus.
A kind of Overhead Transmission Line Construction crossing method of rigid step-over support may further comprise the steps:
(1) two cranes that make the arm top that hanging basket is installed are parked in the both sides of railroad bridge, and two operating personnel hand a guiding rope respectively and stand in two hanging baskets (Fig. 1);
(2) arm with two cranes rises to the railroad bridge top synchronously, and two operating personnel throw two guiding ropes to railroad bridge respectively, and the middle staff of railroad bridge that is positioned at of wait guides rope butt joint (Fig. 2) with two;
(3) two cranes progressively rotate to the position parallel with railroad bridge also will guide rope tension (Fig. 3);
(4) two crane rotations are to the position parallel with railroad bridge, and guiding rope pulling traction rope is by railroad bridge, and the steel wire rope that will be connected the suspension arm of crane front end simultaneously is separately fixed at ground earth anchor place (Fig. 4);
(5) pull rope pulling cable is by railroad bridge, complete operation process (Fig. 5).
