The anti-loosening and anti-overloading quick clamping mechanism comprises an upper framework, an upper guide sleeve, a clamping rod, a lower guide sleeve, a lower framework, a safety clutch mechanism, an outer ring, screws, springs, steel balls, a square shank, a connecting rod, a worm anti-loosening device, a worm gear, the worm and scales. The upper guide sleeve is arranged on the upper framework, the lower guide sleeve is arranged on the lower framework, the safety clutch mechanism is arranged on the clamping rod, and the scales are arranged on the clamping rod. By the aid of the anti-loosening and anti-overloading quick clamping mechanism, problems of excessive clamping, easiness in loosening and low debugging efficiency due to an existing clamping mechanism for a cable robot can be solved, and the anti-loosening and anti-overloading quick clamping mechanism has the advantages of simple structure, reasonable design and easiness in manufacture.
Description
Technical field
The utility model belongs to field of special robots, more particularly, relates to a kind of robot and climbs and clamp the worm screw 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 worm screw anti-loosing type cable robot antioverloading quick clamping mechanism.
For addressing the above problem, the utility model adopts following technical scheme.
A kind of worm screw anti-loosing type cable robot antioverloading quick clamping mechanism, comprise 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, upper fairlead is provided with screw thread, clamping bar lower end is through lower fairlead, the threaded engagement of upper end and upper fairlead, described clamping bar top is provided with scale, lower end is provided with insurance clutch and worm screw locking device, described insurance clutch is by outer ring, screw, spring, steel ball, side's handle composition, described outer ring is connected with clamping bar, described square handle is connected with connecting rod, described screw is assemblied in the screwed hole of outer ring, described handle surface, the steel ball side of being pressed on, between described screw and steel ball, be provided with spring, described worm screw locking device is by worm gear, worm screw composition, described worm gear is assemblied on connecting rod by key, described worm screw is assemblied on lower bearing bracket by rolling bearing, and be meshed with worm gear.
Described steel ball is stainless shot, and described spring is Compress Spring, and the angle of spiral of described worm screw is less than the equivalent friction angle of the field of conjugate action of itself and worm gear.
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 ensure the reliable clamping of clamp mechanism, prevented again the excessive clamping for cable.
(2) the utility model utilizes worm geared self-locking performance to realize the locking of clamping bar, make clamping bar can not occur becoming flexible because of the effect of the vibration of cable and robot, ensure the reliability of robot clamp mechanism work, locking reliable and compact conformation.
(3) the utility model is provided with scale on clamping bar, makes in the time that debugging machine people's clamping is lax, ensure 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.
