Abstract
The utility model relates to a cable angle-adjusting machine, which comprises two S-shaped holding arms, a support bar and a suit of hydraulic pressure driving gear. The utility model is characterized in that both ends of the support bar are respectively hinged with the ends corresponding to the holding arms, and the end of a piston rod and the end of a cylinder sleeve of a hydraulic oil cylinder of the hydraulic driving gear are respectively hinged with the corners of two holding arms. The cable angle-adjusting machine can be conveniently and reliably used for straightening or bending cables in electric power cable laying and execution of works with a large cross section.
Description
The utility model relates to the isolated plant in a kind of power cable cable laying operation, particularly relates to a kind of cable angle-adjusting machine that power cable a certain section in heavy in section can be bent to required radian.
In cable laying or joint construction, the often radian or the alignment of the crooked a certain part of palpus.Often need for the crooked of electric cable with large cross-section by isolated plant.Existing cable angle-adjusting machine is by two S shape gripper jaws, and compositions such as a support bar and hydraulic jack, two ends of support bar are hinged with the corner of two gripper jaws respectively, and the end of oil cylinder and piston rod end thereof are hinged with the corresponding end of two S shape gripper jaws respectively.During work, piston rod is done to shrink and is moved, and like this, the working sections of piston is long-pending less, and the operating efficiency of hydraulic jack is on the low side.
For the operating efficiency of the hydraulic jack that improves the cable angle-adjusting machine, the purpose of this utility model provides a kind of piston rod and is in when work and upholds the cable angle-adjusting machine that moves.
A kind of cable angle-adjusting machine of the present utility model, comprise two clamping limbs, each clamping limb has a fulcrum of forming a plane triangle and two stress points that rotate around it, and is extending a gripper jaw in the same way perpendicular to the described plane triangle of clamping limb respectively from two stress points; One support bar, its two ends are hinged with an end of the corresponding galianconism of two clamping limbs respectively; One cover comprises the fluid pressure drive device of a hydraulic jack, oil pump and pipeline, its cylinder sleeve one end of described hydraulic jack and the piston rod end of stretching out respectively with two clamping limbs near hinged with the corner that is hinged of support bar.
Cable angle-adjusting machine of the present utility model, its support bar is proper and existing opposite with the installation site of hydraulic jack, when working, the piston rod of hydraulic jack does to uphold to move, like this, just make that the working sections area of piston is increased greatly, thereby improved the operating efficiency of oil cylinder, and then helped improving the angle-adjusting machine operating efficiency.Therefore, this cable angle-adjusting machine can be used for cable laying when construction more reliably, neatly to the cable alignment or bend to required radian, also can improve the efficient of construction simultaneously and alleviate working strength.
Now in conjunction with the accompanying drawings most preferred embodiment of the present utility model is elaborated, with further elaboration feature and advantage of the present utility model.Wherein:
Fig. 1 is the structural representation of a kind of cable angle-adjusting machine of the present utility model;
Fig. 2 is the vertical view (not being with oil pump) of cable angle-adjusting machine shown in Figure 1;
Working state figure when Fig. 3 is expression cable angle-adjusting machine bending cable shown in Figure 1.
As shown in Figure 1, 2, a kind of cable angle-adjusting machine of the present utility model comprises:
Two clamping limbs 1 and 2, each clamping limb has a fulcrum 4 ' of forming a plane triangle or 5 ' and two stress points 1 ' that rotate around it, a or 2 ', b, for example, clamping limb can be made the S shape shape that can allow electric cable with large cross-section pass through in the present embodiment, respectively there is a gripper jaw 101,101 ' and 201,201 ' that extends in the same way perpendicular to clamping limb 1,2 described plane triangle at the two ends of each clamping limb.
One support bar 3, its two ends are hinged with the corresponding end 4,5 of two clamping limbs 1,2 respectively.
One hydraulic jack 7, it has a single-rod piston 9, the overhanging end of its piston rod is hinged by the corner of connector 8 with the close of left clamping limb 1 and the place, end that support bar is hinged, and the end of its oil cylinder 7 is hinged by the corner of a hydraulic cylinder connector 8 ' with the close of right clamping limb 2 and the place, end that support bar is hinged.Sidewall at hydraulic jack 7 has an inlet connector 701, uphold mobile left by oily its inflow oil cylinder 7 back promotion pistons 9 that pass through of high-pressure and hydraulic that oil pump 11 is sent here by pipeline 15, two clamping limbs 1,2 are relatively rotated, thus can be with the cable bending (see figure 3) of its clamping.At this moment, act on oil pressure pressure on the piston rod 9 and cable when crooked reaction force to clamping limb balance each other; This moment piston rod 9 and support bar 3 all be under pressure (acting on it respectively) by left and right clamping limb.In order to prevent to make clamping limb 1,2 excessive bending cables cause damage, can select the oil pump that has the uniaxial pressure control valve for use because of oil pressure is too high.When in the hydraulic circuit during oil pressure pressure overrate, thereby a part of pressure oil promptly guarantees that by the one-way control valve earial drainage oil sump tank (not shown) of oil pump pressure is unlikely too high.In addition, can be connected in series an oil pressure Pressure gauge 10 to show the actual working pressure value in the oil circuit at oil pump 11 oil outlet ends by a joint 12.The operating pressure oil of hydraulic jack 7 can be provided by a hand-hydraulic pump or an engine-driven hydraulic pump.For the ease of mounting or dismounting, two ends of high-pressure oil pipe 15 all can be furnished with oil pipe snap joint 14 and 16, and they can connect with oil cylinder 7 fuel inlet fittings 701 and pressure tapping 12 or shirk soon.
When carrying out bending (or alignment) cable, (see figure 3), after earlier cable 18 being penetrated left and right sides gripper jaw 101,101 ' and 201,201 ' hydraulic oil pump 11 and pressurizeing gradually, piston rod 9 stretches out, by shoring of support bar 3, respectively does respectively counterclockwise around the two ends 4,5 of support bar 3, clockwise direction relatively rotates by clamping cable 18 for the sandwich pawl, directly only cable by alignment or bend to predetermined requirement.
In order to prevent that gripper jaw from crushing cable 18, can be on all gripper jaws the fixing rubber sleeve of suit oil resistant, acid and alkali-resistance, wear-resisting wiping.Support bar 3 material therefors can be No. 45 seamless steel pipes; Left and right sides clamping limb can adopt the ZL104 aluminum alloy materials to cast, and critical section adopts rectangle to obtain than high-flexural strength.
