Cable laying is a very common and very important operation in electrical system construction.The quality of cable laying directly affects progress and the quality of whole engineering.Generally, try one's best horizontal laying or lay along passage, so not only laborsaving but also safety of cable laying.But in some occasion, due to design reasons or be subject to the restriction of site environment, cable testing bridge is vertical, and cable just must vertical run.In cable lifting, common mode is to lay from bottom to top, the speed that this mode can control cables be laid, but if cable upwards when traction drawing head throw off, cable will vertically drop fast, not only want accent dallying over one's work, even may cause the accident.
Utility model content
The purpose of this utility model is to provide a kind of cable lifting safety aid, and in cable makes progress the process of vertical run, this device can effectively stop cable to throw off and drop because of drawing head, thereby has improved efficiency and the fail safe of cable laying.
For achieving the above object, technical solution adopted in the utility model is a kind of cable lifting safety aid, it is characterized in that: it comprises the trunnion axis 4 that two horizontal parallel are placed, the left end of two trunnion axis 4 is installed on the crosspiece of crane span structure 3, the middle part of described trunnion axis 4 is provided with two pinch wheels 5 of pinch wheel 5(that can only single direction rotation cable 1 is clamped, and the direction of rotation of two pinch wheels 5 should guarantee that cable 1 moves upward).
The outside of described pinch wheel 5 is provided with a circle arc groove, and the inside of pinch wheel 5 is provided with ratchet or unilateral bearing, and ratchet or unilateral bearing are enclosed within on trunnion axis 4 and are fixedly connected with it.
The outer surface of described pinch wheel 5 is flexible material.
Between two described trunnion axis 4, be connected with two Flexible Connectors, two Flexible Connectors lay respectively at the both sides of pinch wheel 5.
Described Flexible Connector is spring 6, and the two ends of spring 6 are connected (state of described spring 6 places and stretching) with two described trunnion axis 4 respectively.
Described cable lifting safety aid also comprises support bar 2, and the two ends of support bar 2 are connected with crane span structure 3 with trunnion axis 4 respectively, and forms a triangle.
One end of described support bar 2 and trunnion axis 4 are rotationally connected, and the other end is fixedly connected on (other end of support bar 2 is fixedly connected on the crosspiece of trunnion axis 4 belows on crane span structure 3) on crane span structure 3.
The beneficial effects of the utility model are:
1, the utility model with two can single direction rotation pinch wheel clamp cable, cable can only be moved upward, effectively stop cable to throw off and drop because of drawing head, thereby improved efficiency and the fail safe of cable laying;
The outer surface of the pinch wheel 2, contacting with cable in the utility model is flexible material, has increased the friction between pinch wheel and cable, further stops cable tenesmus;
3, the tension force of the utility model Elastic connector can be adjusted, the quantity of this device can arbitrarily arrange, and can meet the cables of different sizes and the cable laying of differing heights, reduces the number of work high above the ground;
4, the utility model is simple in structure, easy for installation, auxiliary without special tool(s).

In figure: 1-cable, 2-support bar, 3-crane span structure, 4-trunnion axis, 5-pinch wheel, 6-spring.
Embodiment
In order to understand better the utility model, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further to (referring to Fig. 1 to Fig. 3).
A kind of cable lifting safety aid, as Figure 1-3, it comprises the trunnion axis 4 that two horizontal parallel are placed, the left end of two trunnion axis 4 is installed on the crosspiece of crane span structure 3, the middle part of described trunnion axis 4 is provided with two pinch wheels 5 of pinch wheel 5(that can only single direction rotation cable 1 is clamped, and the direction of rotation of two pinch wheels 5 should guarantee that cable 1 moves upward).
The outside of described pinch wheel 5 is provided with a circle arc groove, and the inside of pinch wheel 5 is provided with ratchet or unilateral bearing, and ratchet or unilateral bearing are enclosed within on trunnion axis 4 and are fixedly connected with it.
The outer surface of described pinch wheel 5 is flexible material.
Between two described trunnion axis 4, be connected with two Flexible Connectors, two Flexible Connectors lay respectively at the both sides of pinch wheel 5.
Described Flexible Connector is spring 6, and the two ends of spring 6 are connected (state of described spring 6 places and stretching) with two described trunnion axis 4 respectively.
Described cable lifting safety aid also comprises support bar 2, and the two ends of support bar 2 are connected with crane span structure 3 with trunnion axis 4 respectively, and forms a triangle.
One end of described support bar 2 and trunnion axis 4 are rotationally connected, and the other end is fixedly connected on (other end of support bar 2 is fixedly connected on the crosspiece of trunnion axis 4 belows on crane span structure 3) on crane span structure 3.
One end of described support bar 2 is connected on trunnion axis 4, and can freely rotate; The length of support bar 2 is adjustable, can regulate according to the step pitch between crane span structure crosspiece, makes trunnion axis 4 remain level.
Using method of the present utility model is as follows:
1) according to the spacing of the big or small pre-adjustment trunnion axis 4 of cable 1, this device is being arranged on crane span structure 3, suitably the tension force of regulating spring 6, makes pinch wheel 5 pinch the dynamics moderate (if vertical crane span structure 3 is too high, can increase according to actual conditions the quantity of this device) of cable 1;
2) the cable pulling rope of crane span structure 3 tops is passed from the gap of every group of pinch wheel 5, below, the head of cable 1 is tied up; Hauling machine by top upwards promotes cable 1, now pinch wheel 5 rotations; When cable 1 stops rising or decline due to accident, pinch wheel 5 is because the effect of ratchet (or unilateral bearing) can not be reversed and stopped the rotation, tension force due to spring 6 makes cable 1 stop declining simultaneously, thus security incident and other loss of avoiding cable 1 tenesmus to cause.
The above, be only preferred embodiment of the present utility model, and the technical scheme that all employing equivalents or equivalent substitute mode form, within all belonging in the protection range of the utility model claim.
