Description

A cable straightening pulley bracket

technical field

The invention belongs to the technical field of cable tools, in particular to a cable straightening pulley bracket.

Background technique

When laying cables at the cable branch box, ring network cabinet, and box-type transformer power supply inlet, it is necessary to make and install the cable terminal head, and the insulated core of the cable head must be shaped to facilitate the connection operation of the cable head; when the cable is overhauled It is often necessary to reshape and straighten the original cables. In the prior art, since there is no special cable straightening and shaping tool, it can only be manually operated to directly reshape the cable core. The disadvantage of this method is: It is time-consuming and labor-intensive to straighten and reshape the cross-section cable core, the labor intensity is high, the shaping effect is not good, the construction efficiency is low, and it is easy to cause damage to the insulation core and dirt on the surface of the insulation layer, which affects the safe operation of the cable after it is put into operation.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a cable straightening pulley bracket, including a channel steel frame, a horizontal plate, an upper pulley and a lower pulley; the horizontal plate is fixed on the lower edge of the channel steel frame Above, there are more than 2 hanging shafts on the horizontal plate, the number of the lower pulleys is more than 2, the lower pulleys are hung on the hanging shafts through the central hole, and the upper pulley is provided with a central hole and passes through the shaft The bracket and the lead screw pair are connected to the middle part of the upper edge of the channel steel frame.

A further improvement to the present invention is: the hanging shafts are evenly distributed on the horizontal plate.

It also includes a left handle and a right handle, and the left handle and the right handle are symmetrically installed at both ends of the channel steel frame.

It also includes a disc, which is fixed on the back of one end of the channel steel frame, and a positioning hole is provided on the disc; one end of the right handle is hinged to the center of the disc, and the right handle is provided with a corresponding positioning hole. The right handle is connected with the disc by bolts passing through the positioning holes.

Also includes a docking frame, the docking frame includes a chute plate and a docking pulley, the section of the chute plate is provided with a groove that is adapted to the upper edge section of the channel steel frame, and the butt pulley and the upper pulley structure Same and installed on the chute plate, the upper edge of the channel steel frame is provided with a docking notch, when the chute plate is docked with the upper edge of the channel steel frame through the butt joint notch, the butt pulley is located on both sides of the upper pulley.

The beneficial effects produced by adopting the above technical scheme are: the present invention is simple in structure, convenient and quick to use, uses the pulley to press and contact the cable, avoids damage to the cable and its core, prevents dirt and electrolyte from remaining on the surface of the cable insulating core, and eliminates Defective operation of the cable. Using the invention to carry out cable construction can save time and effort, the effect of cable straightening and shaping is good, the quality of cable installation can be ensured, and the work efficiency can be improved by more than one time.

detailed description

A cable straightening pulley bracket, comprising a channel steel frame 3, a horizontal plate 13, an upper pulley 9 and a lower pulley 11; the horizontal plate 13 is fixed above the lower edge of the channel steel frame 3; There are more than 2 hanging shafts 12, the number of the lower pulley 11 is more than 2, the lower pulley 11 is hung on the hanging shaft 12 through the central hole, and the upper pulley 9 is provided with a central hole and passes through the shaft bracket 14 and The leading screw pair is connected to the middle part of the upper edge 5 of the channel steel frame. The hanging shafts 12 are evenly distributed on the horizontal plate 13 . It also includes a left handle 2 and a right handle 10, and the left handle 2 and the right handle 10 are symmetrically installed at both ends of the channel steel frame 3. Also comprises disc 15, described disc 15 is fixed on the back of one end of channel steel frame 2, and disc 15 is provided with positioning hole 16; One end of described right handle 10 is hinged with the center of disc 15, and right handle 10 Corresponding positioning holes 16 are provided, and the right handle 10 and the disk 15 are connected by bolts passing through the positioning holes 16 .
