Abstract

The utility model discloses a kind of closing adjustable cables to spread line pulley gear, including bracket and pulley blocks, the bracket includes upper bracket, lower bracket and supporting leg, the upper bracket and lower bracket are U-shaped board structure, the lower bracket upper open end is connect with upper bracket lower open end side by folding, the other side is connected by lock uint, and the lower bracket lower end surface is fixedly connected with supporting leg, is equipped at least 2 groups of pulley blocks in the bracket.The pulley gear of the utility model is that closing is adjustable, when handling cable, cable is limited by pulley and bracket, it can make cable is smooth on pulley to move and will not fall off, and bracket may be also secured at various angles and the movement for keeping cable smooth is not fallen off, and is not required to very important person in paving line process and observes at any time.

Description

A kind of closing adjustable cable paving line pulley gear

Technical field

The utility model relates to cable construction fields, and in particular to a kind of closing adjustable cable paving line pulley gear.

Background technique

Existing cable is spread in line process, and the paving line pulley used is open single pulley blocks, due to the inertia of cable And the problems such as spreading the angle of line, when especially cable needs turning, cable is easy to be detached from pulley at this time, and stability is poor, needs People observes and playbacks at any time, therefore easily causes cable bad or personal injury；And pulley blocks are to be fixedly connected with bracket, no Replaceable adjusting, bad adaptability.

Utility model content

The purpose of the utility model is to overcome disadvantages of the existing technology, provide a kind of closing adjustable cable paving line Pulley gear.

To achieve the goals above, the technical solution of the utility model is: a kind of closing adjustable cable paving line pulley dress It sets, including bracket and pulley blocks, the pulley blocks include pulley and crossbeam, and the crossbeam passes through pulley center hole and passes through bearing It is connect with pulley, it is characterised in that: the bracket includes upper bracket, lower bracket and supporting leg, and the upper bracket and lower bracket are U Shaping plate structure, the lower bracket upper open end are connect with upper bracket lower open end side by folding, and the other side passes through sealed dress Connection is set, the lower bracket lower end surface is fixedly connected with supporting leg, and the upper bracket and lower bracket side is symmetrically arranged with several through-holes；

The crossbeam both ends are equipped with cylindrical bump, and the one end of the beam is equipped with groove, is equipped with spring, institute in the groove It states one end of the beam and convex block is connected by spring, the crossbeam other end is directly connected to convex block, in the convex block outer diameter and through-hole Diameter is adapted, and at least 2 groups of pulley blocks are equipped in the bracket, and the convex block at the crossbeam both ends is inserted into through-hole；

The lock uint includes latch hook and lock, and the latch hook is hinged by pin shaft and upper bracket, and the lock is fixed On lower bracket, in the slot of the bill insertion lock of the latch hook.

Further；The through-hole is vertical single-row setting.

The utility model has the beneficial effects that

1) pulley gear of the utility model is closed, and when handling cable, cable is limited by pulley and bracket, It can make cable is smooth on pulley to move and will not fall off, and bracket may be also secured at various angles and enable cable Smooth movement is not fallen off, and is not required to very important person in paving line process and is observed at any time.

2) pulley gear of the utility model is adjustable, can be adaptable according to different cable model adjustable pulley groups.

Specific embodiment

Embodiment:

As shown in Figure 1, a kind of closing adjustable cable spreads line pulley gear, including bracket and pulley blocks, the pulley blocks Including pulley 1 and crossbeam 2, the crossbeam 2 passes through 2 centre bore of pulley and is connect by bearing with pulley 1, it is characterised in that: institute Stating bracket includes upper bracket 3, lower bracket 4 and supporting leg 5, and the upper bracket 3 and lower bracket 4 are U-shaped board structure, the lower bracket 4 upper open ends are connect with 3 lower open end side of upper bracket by folding 6, and the other side is connected by lock uint 7, the lower branch 4 lower end surface of frame is fixedly connected with supporting leg 5, and the upper bracket 3 and 4 side of lower bracket are symmetrically arranged with several through-holes 8, the through-hole 8 For vertical single-row setting；

2 both ends of crossbeam are equipped with cylindrical bump 9, and the one end of the beam is equipped with groove, is equipped with spring in the groove 10, described 2 one end of crossbeam connects convex block 9 by spring 10, and 2 other end of crossbeam is directly connected to convex block 9, the convex block 9 Outer diameter is adapted with 8 internal diameter of through-hole, and upper and lower 2 groups of pulley blocks are equipped in the bracket, and the insertion of convex block 9 at 2 both ends of crossbeam is logical In hole 8；

The lock uint includes latch hook 11 and lock 12, and the latch hook 11 is hinged by pin shaft 13 and upper bracket 3, described Lock 12 is fixed on lower bracket 4, in the slot of the bill insertion lock 12 of the latch hook 11.It is sliding when needing replacing different model When wheel group, lock uint is opened, presses the convex block 9 of 10 one end of connecting spring, pulley blocks is taken out and is replaced.

Embodiment described above is the preferable scheme of the utility model, is not made in any form to the utility model Limitation, on the premise of not exceeding the technical scheme recorded in the claims there are also other variations and modifications.
