The outer end of a piston rod of the hydraulic cylinder is fixedly connected with the booms. Clamping ends of the cable roller are arranged on the booms on one side corresponding to the connecting regions of the booms and supporting rods. Opposite hoisting shafts are fixed on two clamping ends of the cable roller through nuts, wherein, a toothed deflector rod is fixed on one hoisting shaft. The outside of the hoisting shaft is connected with a motor which is fixed on the booms. The utility model has the advantages of high efficiency of construction and labor saving.

Description

Cable rolls lifting, take-up and pay-off device

The utility model relates to a kind of cable constructing device, and especially a kind of cable rolls lifting, take-up and pay-off device.

In the construction in the past, cable arranges there is not a kind of special-purpose machinery, generally be with the vehicle loading cable to the job site, during wiring, drag cable by machinery and roll, efficient is low, poor accuracy, the folding and unfolding of cable is then finished by manual, wastes time and energy.

The purpose of this utility model provides a kind of retractable cable transportation automation, saves manpower, and the cable of raising labour productivity rolls lifting, take-up and pay-off device.

A kind of cable rolls lifting, take-up and pay-off device, it is characterized in that: it comprises two pairs of arms and two arms, paying arm relies on back shaft to be connected with arm, pay arm and back shaft and be fixedly connected into a steel body, back shaft passes arm and flexibly connects with it, and promising two arms in back shaft two ends are free to slide on back shaft and the precision working position that designs; Each fixes a hydraulic cylinder on two pairs of arms, fixedly connected with arm in its piston rod outer end, an example relative with the support bar connecting portion on arm is rolled bare terminal end for cable, two cables roll on the bare terminal end by bolt in opposite directions hoisting axis, wherein have on the hoisting axis and be fixed with toothed driving lever, this fixedly connected key axle in hoisting axis outside, the key axle links to each other by the rotating shaft of key cover with the band key of motor, and motor is fixed on the arm.

Cable of the present utility model rolls in lifting, the take-up and pay-off device because the movably structure of arm, make that the clamping that cable is rolled is very convenient, in addition the cooperation of motor vehicles and machines just can finish easily that cable rolls moves, carrying, place, in addition, because the driving lever of installing on the hoisting axis makes cable roll in clamp position and can rotate with driving lever, automatically finish wiring, take-up and save manpower greatly, improved efficient.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the installation diagram of the utility model embodiment 1;

Fig. 2 is the installation diagram of the utility model embodiment 2.

Embodiment 1

As shown in Figure 1 present embodiment and wheel loader are used.It comprises two pairs of arms 5 and two arms 8, paying arm 5 and arm 8 relies on and drives axle 2 away and link together, arm 8 is positioned at the outside of paying arm 5, pay arm 5 and be fixedly connected into a steel body with back shaft 2, back shaft 2 passes arm 8 and flexibly connects with it, promising two arms 8 in back shaft two ends are free to slide on back shaft 2 and the precision working position that designs, there is spacing back-up ring 3 in its termination portion, each is fixed a hydraulic cylinder 1 its piston rod outer end and fixedlys connected with arm 8 on two pairs of arms 5, for increasing the bonding strength of paying between arm 5 and the arm 8, between pair arm 5 and arm 8, be provided with one and reinforce axle 4, reinforcing axle one end fixedlys connected with a pair arm, the other end passes arm 8 and is fixed by support, and support is fixed on to be paid on the arm 5.A side relative with support bar 2 connecting portions is that cable rolls bare terminal end on the arm 8, be fixed with in opposite directions hoisting axis 10 by nut 11 on the two cable bare terminal ends, embedding cable when hoisting axis uses rolls in the centre bore, cable rolled sling, roll for adapting to different cables, hoisting axis 10 also can be designed different specifications for use, friction installs plane bearing 14 additional between hoisting axis 10 and the arm between hoisting axis 10 and arm when reducing clamping work, the driving lever 12 that is fixed with the band moving tooth above one is arranged in two hoisting axis, this hoisting axis outside is a key axle, the key axle links to each other with the rotating shaft of the band key of hydraulic motor 17 by key cover 16, hydraulic motor 17 is fixed on the support 13, and support 13 is fixed on the arm.

For preventing the wearing and tearing of arm, on the arm that hydraulic motor 17 is installed, be provided with steel or copper interior cover 15 in the open-work that bolt 11 passes.

Because wheel loader itself has complete hydraulic system, utilizes this system, the coupling part line valve just can drive roll extrusion cylinder and rolling motor and realize motion.

The arm of paying in this device is fixedlyed connected by set bolt 6 with the principal arm 7 of wheel loader, to picking up that cable rolls, operation such as puts down with realization.

Embodiment 2

Cable of the present utility model roll lifting, take-up and pay-off device except that as described in example 1 above with wheel loader matches, also can match, as shown in Figure 2 with machineries such as automobile, tractors.

Arm 8 is positioned at the inboard of paying arm 5 among Fig. 2, arm 8 inboard each fix a hydraulic cylinder 1, the piston rod of hydraulic cylinder with pay an arm 5 and fixedly connected, back shaft 2 is positioned at the middle part of paying arm and arm and passes arm fixedlys connected with a pair arm.Because this device needs to match with automobile, tractor etc., so will horizontal positioned when using, be to realize lifting that cable is rolled, pay arm 5 and be designed to bending with an angle, when pair arm 5 one ends were depressed or lift, its bare terminal end can be realized slinging and falling what cable rolled.Automated job in the present embodiment can be by automobile, tractor etc. the power source of machinery such as machine driving, belt transmission, hydraulic drive realize, also can be realized that the remainder structure is identical with embodiment 1 by transmission device independently.

Hydraulic motor in the utility model, hydraulic cylinder can replace as modes such as gear or worm and gears with machinery, fall into protection range of the present utility model but all should be considered as being equal to replacing.
