Technical field
The utility model belongs to field of special robots, more particularly, relates to a kind of robot and climbs and clamp the roller anti-loosing type cable robot antioverloading quick clamping mechanism of use.
Background technology
Cable stayed bridge, as the new model of modern bridge, is worldwide widely used.As the cable long term exposure of one of cable stayed bridge main bearing member, in air, through wind and weather Exposure to Sunlight, the pe sheath on cable surface will produce sclerosis and cracking phenomena in various degree, brings the serious problems such as rust staining, fracture of wire to the steel tendon in sheath; Because Wind induced Random, rain shake, make the steel wire in cable produce micro-friction simultaneously, then cause serious fracture of wire problem, bury serious hidden danger to cable stayed bridge.
In recent years, there is than before larger improvement by pneumatic, the electronic cable robot of many moneys of Shanghai Communications University and Anhui University of Technology's development, the basic general operational requirement meeting cable-maintaining.But in the robot course of work, different cables is safeguarded, and it needs debugging after installing on different cables, especially the debugging of its clamp mechanism, because clamp mechanism is wayward for the pressure of cable, tend to cause clamp excessively, cable is caused to certain damage, and affect the operation of robot.Robot in the course of the work simultaneously, due to the impact of cable and robot self vibration, cause the clamp mechanism of robot to occur loosening, skidding appears in Qing Zeshi robot, heavy cause robot to rush the generation of cable accident, therefore seem most important for the locking design of cable robot clamp mechanism.When robot works on different cables, need to again debug the lax of its clamping, can waste the plenty of time like this, thereby cause operating efficiency low.
Utility model content
Excessive, easy loosening, the low problem of debugging efficiency of clamping causing for existing cable robot clamp mechanism, the utility model provides a kind of roller anti-loosing type cable robot antioverloading quick clamping mechanism.
For addressing the above problem, the utility model adopts following technical scheme.
A kind of roller anti-loosing type cable robot antioverloading quick clamping mechanism, comprises upper spider, upper fairlead, clamping bar, lower fairlead, lower bearing bracket, upper spider is provided with fairlead, lower bearing bracket is provided with lower fairlead, lower fairlead is provided with screw thread, lower fairlead is passed in clamping bar lower end, the threaded engagement of upper end and upper fairlead, and described clamping bar top is provided with scale, lower end is provided with roller locking device and insurance clutch, and described roller locking device is by ratchet, roller, lever, spring, bolt composition, described ratchet is assemblied in clamping bar by key, described lever is in ratchet both sides, be hinged on lower bearing bracket, and away from one end of lower bearing bracket, unthreaded hole is set at lever, and described roller is connected through the hinge on lever, and the two ends of described spring are connected on the lever of ratchet both sides, described bolt is through the reserved unthreaded hole of lever, and described insurance clutch is by outer ring, screw, Compress Spring, steel ball, side's handle composition, described outer ring is connected with clamping bar, and described square handle is connected with manual bolts, and described screw is assemblied in the screwed hole of outer ring, and described handle surface, the steel ball side of being pressed on, is provided with Compress Spring between described screw and steel ball.
Described spring is extension spring, and described bolt is hexagon-headed bolt, and described steel ball is stainless shot.
Than prior art, the beneficial effects of the utility model are:
(1) the utility model utilization insurance clutch prevents the excessive clamping of robot clamp mechanism for cable, according to different conditions of work, the spring of different-stiffness is set, in the time that clamping pressure is excessive, side's handle can occur skidding in insurance clutch, both guarantee the reliable clamping of clamp mechanism, prevented again the excessive clamping for cable.
(2) the utility model utilizes ratchet and roller to realize the locking effect to clamping bar, in the course of the work, the locking to clamping bar due to ratchet and roller, play the locking of clamping bar, and then make clamping bar can not occur becoming flexible because of the effect of the vibration of cable and robot, guarantee the reliability of robot clamp mechanism work.
(3) the utility model is provided with scale on clamping bar, makes in the time that debugging machine people's clamping is lax, guarantee clamp mechanism to the pressure of cable in OK range, thereby complete the fast debugging of robot; Simultaneously making statistical table for robot scale when normal work on the cable of unlike material and diameter, convenient while operating in the future as contrasting, thereby increase work efficiency.
(4) the utility model is simple in structure, reasonable in design, is easy to manufacture.
