As shown in fig. 1 to 3, the protective structure 43 of the trolley for observing dangerous situations provided by the embodiment of the present application comprises a plurality of protective bands 431. Both ends of the plurality of guard bands 431 are connected to both sides of the support main body 41, respectively, to form a ring shape, and the scope 11 is disposed in a guard space formed between the guard bands 431 and the support main body 41. When the observation mechanism 1 further includes the antenna 12, the antenna 12 is also disposed in the shielded space formed between the shield band 431 and the support main 41. The arrangement of the plurality of protective belts 431 not only can play a good protective effect, but also has low cost, and in addition, the weight of the trolley is within a reasonable range. Because many protecting belts 431 form the ring, not only can form the better guard space of protective effect and resist the invasion and attack of external object, simultaneously when the first of dolly and the motion 4 of end were opened, probably this one side of dolly or protecting belt 431 contacts with ground earlier this moment, because protecting belt 431 is cyclic annular, thereby can impel the dolly upset, and then make the opposite side of protecting belt 431, namely walking structure 42 place side contacts with ground, the dolly can get into normal work fast like this. In practical application, the protective belt 431 is made of a material with stronger elasticity, and the protective effect is better.
The number of the protective bands 431 may be two, four, six, etc., which is not limited in the embodiment of the present application. In contrast, four protective belts 431 have better protective effect and reasonable manufacturing cost. Fig. 1 to 3 show four schematic structural diagrams of the guard belts 431 of each movement mechanism 4, wherein two ends of the first guard belt are respectively disposed on two sides of the front end of the supporting main body 41, two ends of the second guard belt are respectively disposed on two sides of the rear end of the supporting main body 41, and planes of the rings formed by the first guard belt and the second guard belt are parallel to each other. Two ends of the third protection belt are respectively arranged at two sides of the front end of the support main body 41, and a plane where an annular shape formed by the third protection belt is located and a plane where an annular shape formed by the first protection belt is located form a preset angle; two ends of the fourth protection belt are respectively disposed at two sides of the rear end of the supporting body 41, and a plane of the ring formed by the fourth protection belt and a plane of the ring formed by the second protection belt form a preset angle. Due to the fact that planes of the first protective belt and the second protective belt are parallel to each other and the preset angle exists, when the trolley is in a linear shape as shown in figure 1 or figure 3 or in a ring shape as shown in figure 2, the trolley can achieve comprehensive protection on the moving mechanism 4, the observation mechanism 1, the opening and closing mechanism 2 and the hinge mechanism 3 located at the joint of the front moving mechanism 4 and the rear moving mechanism 4.
As shown in fig. 1 and 3, the hinge mechanism 3 of the cart for observing hazardous situations includes a hinge shaft and a hinge lever 31. The tail end of the supporting body 41 of one motion mechanism 4 and the head end of the supporting body 41 of the other motion mechanism 4 are both provided with an articulated shaft, the axis of the articulated shaft is vertical to the motion direction of the trolley, and through holes at two ends of the articulated rod 31 are respectively sleeved on the articulated shaft. The hinge structure that this application embodiment provided, simple structure easily realizes.
Since the first and last moving mechanisms 4 of the trolley are fixed or opened to make the trolley be annular or linear, if the hinge mechanism 3 only includes the hinge shaft and the hinge rod 31, the connection between the adjacent moving mechanisms 4 of the trolley may be unstable, and there is a risk of loose fixation or large swing during the moving process.
