Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, a lifting device for an integral framework of a vertical column and a roof girder comprises an integral framework consisting of a vertical column and a roof girder, and further comprises a lifting frame;
the lifting frame is in a triangular cone shape and consists of three support rods 2 with equal length, the top ends of the three support rods 2 are connected, pulleys 1 are arranged at the joints, the bottom end of each support rod 2 is supported on the ground, and a connecting rod 3 is connected between every two adjacent support rods 2; the whole frame is connected with a nylon rope 4, and the other end of the nylon rope 4 passes around the pulley 1.
Wherein, the support rod 2 and the connecting rod 3 are both made of steel pipes.
As the improvement of embodiment, the upper ends of three bracing pieces 2 are welded each other to form the hoisting frame, connecting rod 3 is respectively welded with bracing piece 2, and the structure is more firm.
As an improvement of the embodiment, the integral frame and the nylon rope 4 are articulated, so that the operation is more convenient.
As an improvement of the embodiment, in order to facilitate moving the lifting frame, a universal wheel may be installed at the bottom end of the supporting rod 2, and meanwhile, in order to ensure the stability of the lifting frame when lifting the whole frame, a limiting device for limiting the universal wheel is also installed at the bottom end of the supporting rod 2. According to the demand of using, remove the hoisting frame through the universal wheel, fix the hoisting frame through stop device.
Referring to fig. 2, the specific operation flow of the lifting device is as follows:
1) preparing a steel pipe, a pulley 1 and a nylon rope 4 with enough length, welding the steel pipe to form a required triangular conical lifting frame, and installing the pulley 1 at the top;
2) assembling the upright posts and the roof girders to be installed into an integral frame in advance, and placing the integral frame in sequence;
3) as shown in fig. 2 (a), placing a hoisting frame on one side of an integral frame to be installed, wherein two support rods 2 are supported on one side of the integral frame to be installed, the other support rod 2 is supported at the rear, one end of a nylon rope 4 penetrates through a pulley 1, the other end of the nylon rope is tied on a roof girder, the rope needs to be tied into a movable joint, and enough length is left at two ends of the rope;
4) as shown in fig. 2 (b), 2-3 persons stand under the lifting frame, and slowly lift the whole frame along the front two support rods 2 by pulling the nylon rope 4 on the pulley side;
5) as shown in fig. 2 (c), after the integral frame is in place, workers on both sides install pedestal bolts to reinforce the frame beam;
6) the operator drags the nylon rope 4 at the roof beam end to open the knot;
7) as shown in fig. 2 (d), the hoisting frame is moved to perform the next mounting of the entire frame.
The utility model discloses a hoisting device, processing is convenient, with low costs, and the efficiency of construction is high.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
