Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

As shown in fig. 1 and 2, the lifting type crossing frame convenient to install according to the present invention includes a supporting mechanism 50, a moving mechanism 10, a lifting platform 20, a plurality of supporting rods 30, and an installing rod 40, which are connected in sequence from bottom to top. The bearing mechanism 50 includes a bearing plate 53, and the bearing plate 53 is connected to the moving mechanism 10 through a lifting mechanism 60. The mounting bar 40 is fixed to the elevating platform 20 by the support bar 30.

When the lifting type crossing frame needs to be used, the lifting type crossing frame is moved to a proper position through the moving mechanism 10, then the bearing plate 53 is lowered to the position where the bearing plate 53 is contacted with the ground through the lifting mechanism 60, so that the contact area of the lifting type crossing frame and the ground is increased, the whole weight of the lifting type crossing frame is dispersed, the installation convenience and the construction safety of the lifting type crossing frame are improved, and the phenomenon of sinking caused by soft soil in the using process and even safety accidents are effectively prevented.

As shown in fig. 2, the moving mechanism 10 includes a moving plate 11 and a plurality of moving wheels 12; the moving wheel 12 is rotatably connected with the moving plate 11. In the use, the removal wheel 12 can with lift formula crossing structure removes suitable position so that the construction, also can conveniently carry out timely transition work simultaneously.

As shown in fig. 1, a plurality of lifting platforms 20 are provided, and the plurality of lifting platforms 20 are stacked in sequence from bottom to top and connected by bolts; the lifting platform 20 at the bottom end is fixedly connected with the moving plate 11, and the lifting platform 20 at the top end is fixedly connected with the mounting rod 40. After the bearing plate 53 contacts with the ground, the lifting platform 20 is controlled to be lifted to a proper height by an external controller, and then the safety protection net is installed on the installation rod 40 for protection.

As shown in fig. 2, the lifting mechanism 60 includes a plurality of lifting screws 62. The lifting screw 62 is in threaded connection with a lifting pipeline 61, and the lifting pipeline 61 is fixedly installed on the moving plate 11. The lifting screw 62 penetrates the moving plate 11 and is mounted on the bearing plate 53 through a bearing.
