Abstract

The invention provides a multipurpose cable corner protective laying pulley block which comprises a keel outer frame composed of four bar-shaped keels and is firmly connected through an upper keel connection plate, a lower keel connection plate, an inner keel connection plate and an outer keel connection plate. The keel outer frame is in the shape of an L-shaped corner, a chamfer is arranged at the corner, and a plurality of roller pillars are sequentially arranged in the keel outer frame at intervals to form the pulley block, wherein an included angle of 90 degrees is arranged between every pair of the adjacent roller pillars. The invention further discloses a method for laying cables with the device. The method and the device can meet the requirement for protective laying of cables at the corner of a cable horizontal channel or a cable vertical channel and can save labor and improve the working efficiency.

Description

Multipurpose cable corner protectiveness laying pulley group

Technical field

The present invention relates to the cable construction technical field, refer more particularly to the multipurpose cable corner protectiveness laying pulley group that can be used for cable horizontal channel or Vertical Channel corner.

Background technology

In the heavy construction work progress, particularly, in the process of construction of large industrial buildings, need to lay a large amount of heavy in section power cables and provide power supply for production equipment.Cable passage is usually designed to the forms such as underground cable tunnel, ground cable channel, cable channel, vertical cable shaft, but because the factor such as equipment point is many, building structure is complicated, there is the situation of a large amount of horizontal corner and perpendicular corners usually in cable passage, so it is unavoidable to run into the situation of corner during cabling.During due to cabling, corner easily forms injury to cable covering, and, because the corner resistance increases, causes the cable laying work difficulty to become large.

At present, occurred the cable laying assembly pulley of some variety classeses and pattern on market, the appearance of these assembly pulleys has solved the problem in the cable laying process to a certain extent, has also played the effect of saving manpower.But because these assembly pulleys mostly are the assembly pulley pattern that three pulleys form; can not meet different corner cable laying needs fully; and these assembly pulleys are because be the pattern of opening; in the cable laying process; often there will be due to the front and back unbalance stress, cause cable to break away from the situation of assembly pulley.Occur needing the workmen immediately fault point to be processed after cable breaks away from assembly pulley.If cable is very long, front and back instruction disunity, at this moment have active force forward or backward to cable, can produce unpredictable accident to workmen and the cable of processing this fault point.

In order to address these problems, we need to invent a kind of instrument, a series of construction problems that run into while effectively solving the cable laying of cable passage corner.

Summary of the invention

Technical problem to be solved by this invention is the technical deficiency over against above-mentioned existence; provide a kind of cable protection that can meet cable horizontal channel or Vertical Channel corner to lay; and the saving manpower, the multipurpose tool multipurpose cable corner protectiveness laying pulley group of increasing work efficiency.

The technical solution adopted for the present invention to solve the technical problems is:

Multipurpose cable corner protectiveness laying pulley group; it is characterized in that: include the keel outrigger that four strip keel form; and by upper lower keel connecting plate, and interior outer keel connecting plate is connected firmly, described keel outrigger is the L-type corner shape; and be provided with around the corner chamfering; in keel outrigger inside, a plurality of rollers equidistantly are installed and form assembly pulley, wherein; every a pair of adjacent roller post, all become 90 degree angle settings.

In such scheme, between the bottom keel of described keel outrigger, also be equipped with for strengthening the keel bottom liner of keel outrigger intensity.

In such scheme, between the top keel of described keel outrigger, also be equipped with for covering tightly the pressing plate suitable for reading of cable.

In such scheme, the outside of described keel outrigger, also be equipped with the overhanging connecting plate of being convenient to be installed at turning.

The use step of apparatus of the present invention:

1), before cable laying, in the corner of cable trough passage, adopt expansion bolt that the keel outrigger of multipurpose cable corner protectiveness laying pulley group is fixed on the cable furrow bank;

2), before cabling, cable to be laid one end is passed to pressing plate suitable for reading below, and through roller, assurance can directly be taken out cable after unclamping pressing plate suitable for reading, then by platen cover suitable for reading, with connecting bolt, it is connected with the keel outrigger;

3) carry out cable laying;

4) after treating that cable laying is in place, connecting bolt is unclamped, open multipurpose cable corner protectiveness laying pulley group pressing plate suitable for reading, cable is taken out and is placed on the respective cable crane span structure or on cable bearer;

5), after completing cable laying, take off multipurpose cable corner protectiveness laying pulley group.

The principle of apparatus of the present invention is, mounting and installation assembly pulley around the corner, assembly pulley adopts a plurality of equidistant one-tenth 90 degree angle settings, can make cable when being laid, stressed being adjacent on assembly pulley, and slide with the rotation of assembly pulley, play the effect reduced wear, because assembly pulley is into the setting of an angle of 90 degrees degree, therefore can carry out the location of X and Y both direction, prevent that cable and keel friction from producing loss.

Main beneficial effect of the present invention is:

1, practical, can overcome cable passage corner and easily cause cable protection damage layer and corner's resistance to be difficult for greatly the problem of laying;

2,, by the application of assembly pulley, can realize the purpose of saving manpower, increasing work efficiency;

3,, by the structural design of assembly pulley, can effectively avoid cable to break away from assembly pulley and produce accident potential.
