Background technology
When Production of Strip Mine operation, it is necessary to cable laying is that electrical equipment is powered. Such as, in mining power supply system, usually adopt mine cable for electric line. For electrical equipment is laid in mine cable process under mine, because of the continuous propelling of engineering, also constantly changing of the position of electrical equipment, the position of cable also needs corresponding variation, often need to adopt near vehicle drag cable to electrical equipment, to ensure that electrical equipment can normally use.
Before drag cable, adopting insulation rope that cable is bundled in the vehicle for pulling, insulation rope may be bundled in end or the middle part any position of cable. In drag cable process, the pulling force that vehicle is supplied to cable will all act on insulation rope and cable junction. For the cable that weight is bigger, vehicle needs to provide bigger pulling force to be dragged to cable, and in insulation rope and cable junction, insulation rope may because of by the excessive cable of tying tight of power, even entering in the insulation layer of cable, insulation rope will there will be extremely curved with the junction of cable. Extremely curved referring to the minimum permission crooked process radius that the actual crooked process radius of cable is less than cable, the minimum permission crooked process radius of cable is generally 10 to 25 times of the outside diameter of cable. When cable occurs dead curved time, the insulation layer of cable, by damaged, even damage the wire of insulation layer inside, causes the cable can not normal power-up. If using aforesaid method drag cable frequently, it is possible to many places can be caused on cable extremely curved, increasing the failure rate of cable, affecting quality of power supply and the power supplying efficiency of cable.
Consequently, it is desirable to a kind of cable dragging device, in drag cable process, avoid causing cable occurs extremely curved.
Practical novel content
In view of this, the purpose of this utility model is to propose a kind of cable dragging device, solves cable and is pulling in process, causes because local pressure is excessive cable to occur extremely curved, affect the problem of the normal use of cable.
Based on a kind of cable dragging device that above-mentioned purpose the utility model provides, comprising: card groove, described card groove comprises base plate and the sidewall upwards extended from the relative both sides of described base plate, and the cross section of described plate upper surface is circular arc; Sidewall described in side is provided with the support of two opposing parallel settings; Movable clamp, described movable clamp bottom is provided with mounting block, is provided with card-bit part on front side of top, and behind top, side is provided with web member, and described mounting block and described support are articulated and connected; Described card-bit part can cover above sidewall described in the both sides being buckled in described card groove, and described card-bit part is for being fixed in described card groove by cable; Described web member is for being fixedly connected with stay cord.
Preferably, the bending radius of described base plate is more than or equal to the minimum permission bending radius of described cable.
Preferably, described support is provided with through hole, and the described mounting block of described through hole and described movable clamp passes through pinned connection.
Preferably, the described mounting block of described movable clamp is the first through hole, and described first through hole and described support pass through pinned connection.
Preferably, the described card-bit part of described movable clamp is snap ring, and described snap ring is semi-ring or non-close ring, and the two ends of described snap ring can lay respectively at above sidewall described in the both sides of described card groove.
Preferably, the cross section of the internal surface of described snap ring is circular arc.
Preferably, the described web member of described movable clamp is the 2nd through hole, and described 2nd through hole is for connecting described stay cord.
