When the left supporting leg 2 and the right supporting leg 3 are only fixed with the bottom surface in the box body 1, the gravity load of the whole box body 1 is concentrated on the bottom surface, and the load can be dispersed to the top surface of the box body 1 through the supporting plate 4 and the supporting columns 5, so that the load of the box body 1 is optimized.
In order to further avoid the situation that the load of the top surface of the box body 1 in a local area connected with the supporting columns 5 is too high, the top parts of the supporting columns 5 are fixedly connected with cross beams 7, the cross beams 7 are detachably connected through bolts, the cross beams 7 are connected with two side walls of the box body 1 and attached to the top surface in the box body 1, and the pressure intensity of the local area is reduced.
Preferably, a base 13 is arranged on the inner bottom surface of the box body 1, the left leg 2 and the right leg 3 are arranged on the base 13, and the base 13 is provided with two groups and is symmetrical about the middle of the box body 1. If on the bottom surface with left landing leg 2 and right landing leg 3 direct mount in box 1, the tip of the horizontal movable landing leg 22 of a left side can only link to each other with the tip of the vertical cover body 23 of a left side, but the focus of the vertical cover body 23 of a left side is higher than the horizontal movable landing leg 22 of a left side, the overall structure of the horizontal movable landing leg 2 of a left side is not stable enough, base 13 can be too high left landing leg 2 and right landing leg 3's position, the tip that makes the horizontal movable landing leg 22 of a left side links to each other with the vertical cover body 23 of a left side near the centrobaric position of middle part, improve the holistic stability of equipment, it is also more reasonable to make the equipment atress, right landing leg 3 is the same reason.
Specifically, a bottom plate 11 is fixedly arranged on the bottom surface of the box body 1, and the fixing mode can be welding fixing or detachable connection fixing such as bolts. As shown in fig. 4, the connecting member 6 includes two fixing plates 62 disposed opposite to each other (the fixing plate 62 attached to the side wall of the right leg 3 is hidden in the figure), a connecting plate 63 connecting the two fixing plates 62, a fixing block 64 disposed between the fixing plates 62, and a connecting rod 65 connecting the fixing block 64 and the base plate 11, wherein the top of the connecting plate 63 is integrally connected to the fastening block 61. The two fixing blocks 64 can enhance the overall structural strength of the connecting member 6, and also facilitate the fixing of the fixing blocks 64 and the connecting rod 65.
Preferably, the connecting rod 65 is a screw rod, the connecting rod 65 penetrates through the fixing block 64 to be in threaded connection with the connecting plate 63, and the connecting rod 65 is sleeved with a locking nut 66 for fixing the connecting rod on the fixing block 64.
Compared with the prior art, the technical scheme of the application has the following beneficial technical effects:
this scheme with left branch leg 2 and 3 fixed mounting of right branch leg inside box 1, support fixedly to box 1 when stretching out, seal box 1's breach when withdrawing, but this equipment car is on-vehicle, also can the on-vehicle use of track flatbed, be applicable to in tunnel operation construction scenes such as plateau, high and cold, high gas, unmanned area, whole device simple structure, rationally distributed, box 1 overall structure's load distribution is even, has good application prospect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
