Description

A grid lifting device

technical field

The utility model relates to a grid lifting device.

Background technique

The grid frame is a space structure formed by connecting multiple rods through nodes according to a certain grid form. The basic units that make up the grid include triangular pyramids, triangular bodies, cubes, truncated quadrangular pyramids, etc. These basic units can be combined into planar triangles, quadrilaterals, hexagons, circles or any other shapes. It has the advantages of space force, light weight, high rigidity, and good seismic performance; it can be used as a roof for gymnasiums, theaters, exhibition halls, waiting halls, stadium stand awnings, hangars, two-way large-column grid structures and workshops, etc. cover. The disadvantage is that the number of rods that meet at the nodes is large, and the fabrication and installation are more complicated than the planar structure.

The construction and installation methods of grid structure are divided into two categories: one is the overall jacking method and overall hoisting method assembled on the ground; Assembling and other methods.

The equipment used in the existing installation method is relatively heavy, the lifting speed is slow, the cost is high, and the long-distance transportation cost is high. In order to overcome the above shortcomings, it is necessary to develop a grid lifting device with simple structure, low cost and low construction difficulty.

Detailed ways

With reference to Figures 1 to 7, a network frame jacking device includes a number of jacking frames 1, a jacking column 2 for connecting adjacent jacking frames, a jacking plate 3, a base 4 and a jacking triangular cone 5, The jacking frame 1 includes an equilateral triangle bracket composed of three connecting rods 11, and the adjacent connecting rods 11 are detachably connected by flanges 12, and the jacking frames 1 are arranged up and down. The jacking column 2 is detachably connected to the adjacent flanges 12 in the vertical direction. The jacking plate 3 is an equilateral triangle, and a jacking cylinder 31 is provided at its center of gravity. When the jacking plate 3 is placed on the When the jacking frame 1 is inside, the three corners of the jacking plate 3 extend to the three flanges 12, and the jacking plate 3 can be detachably arranged in the jacking frame 1 through bolts and other parts. The jacking triangular cone 5 is connected with the uppermost jacking frame, the base 4 is connected with the lowermost jacking frame, and the center of the base 4 is provided with a base 41 for fixing the hydraulic cylinder. As shown in FIG. 5 , a rice-shaped support is provided in the base 4 for reinforcement, and a corresponding flange connected to the jacking frame 1 is provided.

As shown in Figure 2, the two ends of the connecting rod 11 are provided with a connecting plate 13, the connecting plate 13 is provided with a through hole, and the flange 12 is provided with a through hole matched with the through hole. hole two. The connecting plate 11 has an arc matching the flange 12 . In the figure, the number of through holes 1 is 2, and the arrangement of the 2 through holes 1 matches with the 2 adjacent through holes 2 on the flange 12, that is, one end of the connecting plate 11 can pass through 2 bolts. The fixing with the flange plate 12 is completed, and quick disassembly and assembly can be realized.

As shown in Figures 6 and 7, the jacking triangular cone 5 is an equilateral triangular cone, which is welded by welding balls and steel pipes, and its top is provided with a string ball 51 for jacking up the grid frame to be lifted. The three corners are provided with flanges for connection with the jacking frame on the lower floor.

As shown in FIG. 4 , the lifting plate 3 is provided with three ribs 32 along its three vertical lines for strengthening the lifting plate 3 .

In actual construction, select some suitable fulcrums, fix the base 4 on the ground, install a hydraulic cylinder on the base 41 in the center of the base 4, and then set the jacking frame with the jacking plate 3 as shown in Figure 4 1. The lower part of the jacking frame fixes the jacking column 2 through the flanges 12 at its three corners, so that the lower end of the jacking column 2 is aligned with the flange on the base 4. A jacking triangular cone 5 is installed above the jacking frame 1, and the jacking triangular cone 5 supports the network frame to be lifted. Simultaneously open the hydraulic cylinders to lift the net frame for a certain distance, which is roughly slightly higher than the height of the jacking column 2. Then install the next section of the jacking frame by the jacking column under the jacked up jacking frame, and lower the hydraulic cylinder. Finally, remove the jacking plate 3, install it in the lowermost jacking frame, and continue the above process. As a result, the grid is lifted layer by layer.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And modification should also be regarded as the protection scope of the present utility model.
