Abstract
The utility model discloses an anti-jump-off pulley and joint plate, which is matched to be used. The frame of a pulley is added with a division bar. The division bar divides the upper side of a pulley block and the frame into a few passages to prevent a thread from jumping off the pulley. A gap is arranged between the lower end of the division bar and the rim of the pulley. A joint plate has a tendon. When the joint plate draws transmission lines through the pulley, a tendon part passes through from a pulley groove and a no tendon part passes through the gap between the division bar and the rim of the pulley.
Description
The utility model relates to a kind of stringing constructing device, especially can prevent the coaster and the yoke plate of clue job-hopping.
At present, known releasing pulley is made up of assembly pulley and framework, and yoke plate is the steel plate that one and bob-weight and spinner link.Spinner connects split conductor and hauling rope, the purpose that hauling rope realizes drawing split conductor by yoke plate, but existing coaster and yoke plate can not prevent the clue job-hopping, and the clue job-hopping is the key factor of restriction raising stringing construction speed.
The purpose of this utility model provides a kind of coaster that is used and yoke plate, and it can prevent the clue job-hopping.
The purpose of this utility model is achieved in that on the coaster framework installs parting bead, and parting bead is with the passage that separated by spaces becomes and assembly pulley middle pulley number equates between assembly pulley top and the framework, and the lower end aligned pulley edge of parting bead also leaves the gap.When yoke plate traction lead was crossed coaster, the muscle portion and the lead of yoke plate passed through from pulley groove, pass through the gap of no muscle portion between parting bead and pulley edge of yoke plate, and the optimum width of this gap is less than the diameter of guiding rope.Because the compartmentation of parting bead, in the stringing process, clue is difficult for job-hopping, if the gap between parting bead and the pulley edge, then can prevent the clue job-hopping fully less than the diameter of guiding rope.
Owing to adopt such scheme, prevent the job-hopping of stringing construction midline rope, can improve construction speed, especially for the stringing of transmission line of electricity, adopt such scheme will produce great economic benefit.Compare with yoke plate with existing coaster, the utility model only increases parting bead and partly changes the design of yoke plate, is easy to make.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 five takes turns the coaster scheme drawing.Wherein four parting beads only mark one.The gap of four parting beads and pulley edge only marks one.
Fig. 2 is a traction conductors on quad bundled yoke plate scheme drawing, and wherein tibet cinnamon bark only marks one.
Among the figure 1: parting bead 2: the gap 3 between parting bead and the pulley edge: muscle
In Fig. 1, four parting beads are divided into five passages with the space between assembly pulley top and the framework.The lower end aligned pulley edge of parting bead also leaves the gap, and the width in gap is less than the diameter of guiding rope.When yoke plate traction conductors on quad bundled passed through coaster, its muscle portion passed through from pulley groove, and no muscle portion passes through the gap between parting bead and pulley edge, and like this, yoke plate just can draw conductors on quad bundled and pass through coaster.Because in guiding rope, hauling rope, sub-conductor, the diameter minimum of guiding rope is so in the process that whole conductors on quad bundled sets up, clue can not be job-hoped.
Claims (2)
1, a kind of wires-erecting pulley is made up of assembly pulley and framework, it is characterized in that having on the framework parting bead (1), and the passage that parting bead becomes to equate with the pulley number with the separated by spaces between assembly pulley top and the framework is between parting bead and the pulley edge gapped (2).
2, a kind of yoke plate is characterized in that having on it muscle (3), and the number of muscle is less than or equal to the pulley number, when yoke plate is crossed coaster, has muscle portion to pass through from pulley groove, and no muscle portion passes through the gap between parting bead and pulley edge.
