Abstract
The utility model discloses an anti-loosening quick clamping mechanism with a worm for a cable robot, and belongs to the field of specialized robots. The anti-loosening quick clamping mechanism comprises an upper framework, an upper guide sleeve, a clamping rod, a lower guide sleeve, a lower framework, 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, threads are arranged on the upper guide sleeve, one end of the clamping rod penetrates the lower guide sleeve, the other end of the clamping rod is meshed with the threads of the upper guide sleeve, the worm anti-loosening device is arranged on the clamping rod and comprises the worm gear and the worm, the worm gear is assembled on the clamping rod via a key, the worm is assembled on the lower framework via a rolling bearing and is meshed with the worm gear, and the scales are arranged at the tail end of the clamping rod. By the aid of the anti-loosening quick clamping mechanism, problems of easiness in loosening and low debugging efficiency of an existing clamping mechanism for a cable robot can be solved, and the anti-loosening 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 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 robot in the course of the work, 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.While work on different cables due to robot, need to again debug the lax of its clamping, can waste the plenty of time like this, thereby cause operating efficiency low simultaneously.
Utility model content
For easily loosening, the low problem of debugging efficiency of existing cable robot clamp mechanism, the utility model provides a kind of worm screw anti-loosing type cable robot 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 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, described clamping bar is provided with worm screw locking device, described worm screw locking device is by worm gear, worm screw composition, described worm gear is assemblied on clamping bar by key, described worm screw is assemblied on lower bearing bracket by rolling bearing, and be meshed with worm gear.
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, and described worm screw is single start worm, and its section flank profil is spiral of Archimedes.
Than prior art, the beneficial effects of the utility model are:
(1) 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, guarantee the reliability of robot clamp mechanism work, locking reliable and compact conformation.
(2) 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.
(3) the utility model is simple in structure, reasonable in design, is easy to manufacture.

Fig. 2 is the sectional view along A-A line in Fig. 1.
In figure: 1-upper spider, 2-upper fairlead, 3-clamping bar, 4-lower fairlead, 5-lower bearing bracket, 6-worm screw locking device, 7-worm gear, 8-worm screw, 9-scale.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, shown in Fig. 2, worm screw anti-loosing type cable robot quick clamping mechanism of the present utility model comprises upper spider 1, upper fairlead 2, clamping bar 3, lower fairlead 4, lower bearing bracket 5, upper spider 1 is provided with fairlead 2, lower bearing bracket 5 is provided with lower fairlead 4, upper fairlead 2 is provided with screw thread, clamping bar 3 lower ends are through lower fairlead 4, the threaded engagement of upper end and upper fairlead 2, described clamping bar 3 tops are provided with scale 9, lower end is provided with worm screw locking device 6, described worm screw locking device 6 is by worm gear 7, worm screw 8 forms, described worm gear 7 is assemblied on clamping bar 3 by key, described worm screw 8 is assemblied on lower bearing bracket 5 by rolling bearing, and be meshed with worm gear 7.
The angle of spiral of described worm screw 8 is 11 °, and the equivalent friction angle of the field of conjugate action of itself and worm gear 7 is 14 °, and described worm screw 8 is single start worm, and its section flank profil is spiral of Archimedes.
