Abstract
The utility model discloses a paying-off tackle for the corner of a cable draw pit, which comprises a base. The base is of a square frame structure. The four corners of the base are respectively provided with a supporting rod vertical to the base. Two supporting rods arranged around a cable incoming end are higher than the other two supporting rods arranged around a cable outgoing end. A crossbar used for supporting a cable is arranged between the two supporting rods arranged around the cable incoming end, and between the two supporting rods arranged around the cable outgoing end, respectively. The crossbars are in the form of rotating shafts used for reducing the friction force generated by the cable during the traction process. The tops of the supporting rods are connected with a fixing seat used for positioning the supporting rods. The paying-off tackle for the corner of the cable draw pit has the advantages of simple structure and convenient usage. By means of the paying-off tackle, the labor intensity of working staff is reduced and the construction safety is ensured. Meanwhile, the construction efficiency is improved.
Description
Technical field
The utility model relates to the specific purpose tool that uses in a kind of cable line work progress, specifically a kind of cable releasing pulley.
Background technology
Power telecom network is the basis of the communications such as dispatching of power netwoks, information, automation, is the important means of guaranteeing power grid security, stable, economical operation.In recent years, along with the development in city, the project under construction of putting cable underground is more and more.In when construction of putting cable underground toward firmly passing through cable shaft, cable laying is in the process of turnover well head corner, adopt hauling machine that the top of cable is drawn to terminal and go out well head, cable when turnover well head corner and the borehole wall, well head can produce very large resistance and friction, easy scratch cable jacket, grind off the identification informations such as model on oversheath, length, also may cause cable core impaired when serious.
Cable laying working strength in the distraction procedure of turnover well head is large, and efficient is low.For raising the efficiency, prevent that cable is impaired, usually adopt in the mode of well head corner placement releasing pulley and protect cable and conveniently lay.The releasing pulley that uses at present mainly comprises pulley and is used for installing the base that supports pulley; first cable is held up with releasing pulley during the unfolding cable; cable is placed in the pulley groove of pulley; cable travels forward with the rotation of pulley; so both reduce the unwrapping wire resistance, and protected again cable not to be worn.
But in using the process of releasing pulley at cabling, when the cable incoming-outgoing well head, cable can swing to produce along with the torsion that cable hank discharges cable and rock, thereby makes cable deviate to drop from pulley groove; Excessive or cable hank is subjected to the influence of topography can not put timing when the cable hank width, and the well head coaster is very easily turned on one's side, and not only affects the cable laying progress, also may cause security incident, and workmen and pedestrian are damaged.
The utility model content
The utility model technical issues that need to address are to provide a kind of cable shaft corner releasing pulley simple in structure, safe and convenient to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Cable shaft corner releasing pulley, comprise base, described base is frame structure, four edges of base arrange respectively a pole perpendicular to base, be positioned at two poles of long cable section of ingoing line end higher than two poles that are positioned at the cable outlet end, be respectively arranged be used to the cross bar of accepting cable between two poles of described long cable section of ingoing line end and between two poles of cable outlet end; The pole top connects the holder that is used for location supporting rod.
Further improvement of the utility model is: described cross bar is the rotating shaft of the frictional force that is used for reducing the cable pulling process and produces.
Further improvement of the utility model is: the horizontal level of described long cable section of ingoing line end rotating shaft is higher than the horizontal level of cable outlet end rotating shaft.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is simple in structure, and is easy to use, safe, alleviated staff's labour intensity, guarantees construction safety, improved engineering efficient.
When cable wellhead unfolding cable, utilize cross bar to accept cable, avoid the touching of cable and ground and the well head borehole wall, the protection cable is not subjected to frictional resistance, prevents that cable is impaired.Cross bar is arranged between pole, prevents that cable from dropping because rocking to break away from.Cross bar is rotary rotating shaft, has reduced the frictional resistance of cross bar to cable.
The rotating shaft horizontal level of long cable section of ingoing line end has strengthened the movement tendency of cable higher than the horizontal level of cable outlet end rotating shaft, has reduced the friction to cable, and is time saving and energy saving.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, base, 2, pole, 3, rotating shaft, 4, holder.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details:
Cable shaft corner releasing pulley, structure comprise base 1, holder 4 and four poles 2 as shown in Figure 1.Base 1 is frame structure, and the cross section is rectangle, and around fixedly forming, described four poles 2 are steel pipe by four block plates, and one group in twos, two groups of steel pipes are not isometric.
Described four poles vertically are fixedly installed on respectively four edges of base, and wherein one group of long pole 2 is fixed in rectangle minor face two ends, is the end of incoming cables of cable; The shorter pole 2 of another group is fixedly installed on another minor face two ends, is the cable outlet end.Between two poles of long cable section of ingoing line end and between two poles of cable outlet end, two-layer cross bar is being set all, described cross bar is selected the rotating shaft 3 that can reduce cable is produced frictional force, and the axis of rotating shaft 3 is parallel with base 1.Pole 2 top connection fixing bases 4, holder 4 around forming, is used for reinforce stabilization pole 2 by four block plates.
During use, the utility model is placed on the edge of cable wellhead, the cable that need to lay passes rotating shaft between two poles of long cable section of ingoing line end and the rotating shaft between two poles of cable outlet end successively, utilizes the support of rotating shaft 3 and traction and the transmission that cable is completed in rotation.For reaching better transmission effect, reduce the frictional resistance of cable, the horizontal level of long cable section of ingoing line end rotating shaft is set higher than the horizontal level of cable outlet end rotating shaft, like this, the cable that is placed in rotating shaft is ramp-like, and downward movement tendency strengthens to some extent, is conducive to the transmission of cable.
