Description of drawings
Fig. 1 is the perspective view of the transmission shaft backplate of transmission shaft protective device in the utility model;
Fig. 2 is the perspective view of the fail-safe plate of transmission shaft protective device in the utility model;
Fig. 3 is the perspective view of transmission shaft protective device in the utility model.
The specific embodiment
Below with reference to accompanying drawing and preferred embodiment, the technical solution of the utility model is done detailed description.
As shown in Figure 1, be the perspective view of the transmission shaft backplate of transmission shaft protective device in the utility model.The keystone configuration of transmission shaft backplate 11 comprises: top panel 12, left panel 13 and right panel 14; Top panel 12 is the panel of trapezoidal shape; The end of top panel 12 has the butter hole 15 of U type, and this butter hole 15 is used to the butter of annotating; The below in butter hole 15 has first mounting hole 31 and second mounting hole 32 (referring to Fig. 3), and first mounting hole 31 and second mounting hole 32 are used to install fail-safe plate 21.Left panel 13 is the panel of the consistent trapezoidal shape of structure with right panel 14, and left panel 13 and right panel 14 are separately positioned on two sides of top panel 12.Also be provided with sensor on top panel 12, sensor is used for responding to the situation of transmission shaft, takes place if any accident, and sensor can send alerting signal.
As shown in Figure 2, be the perspective view of the fail-safe plate of transmission shaft protective device in the utility model.Fail-safe plate 21 is a U type structure, and U type structural openings makes progress and the bottom is semicircle.Two open ends of fail-safe plate 21 level respectively extend outward first connecting portion 22 and second connecting portion 23.First connecting portion 22 is corresponding with the position of first mounting hole 31, and second connecting portion 23 is corresponding with the position of second mounting hole 32.
