Description

Technical Field

[0001] The invention belongs to the technical field of color steel plate hoisting, and in particular relates to an integral hoisting device for roof color steel plates and a preparation method thereof. Background Art

[0002] The traditional method of lifting color steel plates on roofs is to press the color steel plates on site or have them produced by a manufacturing plant, then transport them to the lifting site, tie the vertical straps of the color steel plates on the lifting rods, add diagonal straps at both ends, and lift them to the roof with a car crane.

[0003] The color steel plates on the roofs of some factories are long. If they are cut and then assembled on the roof, the quality of each weld cannot be guaranteed, and the visual quality will be affected. In addition, it will increase the number of processes, construction costs, and overall construction progress. If the long color steel plates are directly transported to the roof with slings, the rigidity of the color steel plates themselves will limit the deformation of the color steel plates, affecting the quality of the installation. In addition, the length of the color steel plates will have different size requirements as the construction area changes, which increases the complexity of the lifting work. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an integral lifting device for roof color steel plates and a preparation method thereof, so as to solve the inconvenience of existing roof color steel plate lifting, which often requires cutting of the color steel, and the welding of the cut color steel affects the appearance quality, and increases the construction cost and affects the construction progress. The overall handling process easily causes the color steel to deform, which affects the paving quality.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An integral hoisting device for roof color steel plate comprises a plurality of hoisting units spliced ​​with each other, the hoisting unit comprises two spaced bottom beams, the bottom beams are connected as an integral mechanism through a plurality of spaced cross braces, a plurality of spaced pillars are fixed on the bottom beam, a top beam is welded on one end of the pillar away from the bottom beam, a waist beam is also fixed on the pillar between the top beam and the bottom beam, a grid-shaped cover plate is rotatably connected to one of the top beams, and the cover plate is supported on the top beam on the other side after rotation, the bottom beams at one end of the hoisting unit are extended forward for a section to form a receiving section, the bottom beams at the other end of the hoisting unit are also extended forward for a section to form a plug-in section, the bottom beams between the plug-in sections are connected through cross braces, the bottom beams of the plug-in section are also vertically welded with pillars, the ends of the waist beam and the top beam are extended and welded on the pillars, and two adjacent hoisting units are spliced ​​together through the plug-in section and the receiving section. The device can adapt to the transportation of color steel plates of different lengths through the splicing of the hoisting units without cutting, and can effectively prevent the color steel plates from deforming through the support of the bottom beam and the cross brace.

[0007] In order to further optimize the lifting device, the scheme can be optimized.

[0008] The two bottom beams are parallel to each other, and the diagonal positions of the quadrilateral formed by the bottom beams and the cross braces are fixed with diagonal rods. The parallel arrangement of the bottom beams can ensure that the cross braces have the same specifications for uniform processing, and the diagonal rods can increase the stability of the bottom beams after welding.

[0009] The bottom beam, waist beam and top beam are parallel to each other. By making the three beams parallel to each other, the strength can be increased while the material usage can be kept to a minimum, thus saving costs.

[0010] The receiving section is provided with a first bolt mounting hole, and the plug-in section is provided with a second bolt mounting hole. After the hoisting units are spliced, they are fixed together by connecting bolts that penetrate the first bolt mounting hole and the second mounting hole. The bolt connection method can be dismantled and reused

[0011] The pillars are parallel to each other and perpendicular to the bottom beam. The vertically arranged pillars can play an equal blocking role on the edge of the color steel plate, and can prevent the color steel plate from shaking back and forth between the pillars and damaging the color steel plate.

[0012] The bottom of the bottom beam is also equipped with universal wheels, which is convenient for carrying and moving the hoisting device after it is filled with color steel.

[0013] The cover plate is formed by welding a plurality of steel plates, which can save materials and prevent the color steel plate from being separated from the lifting device.

[0014] A method for preparing the above-mentioned integral hoisting device for the roof color steel plate comprises the following steps:

[0015] Step 1: Determine the length of the horizontal brace and diagonal rod in the hoisting unit according to the size of the color steel plate to be hoisted;

[0016] Step 2: Cut and cut the bottom beam, end beam, waist beam and pillar, reserve the receiving section and plug-in section on the bottom beam, weld the parallel bottom beams together through the cross brace, then weld the diagonal rod in the quadrilateral formed by the bottom beam and the cross brace, then weld the pillar vertically to the end beam, and weld the end beam and waist beam to the pillar respectively;

[0017] Step 3: Cut and weld the grid-shaped cover plate;

[0018] Step 4: Adjust the lengths of the receiving section and the plug-in section in step 2 so that the two lengths are the same;

[0019] Step 5: Process the first bolt installation hole on the receiving section and the second bolt installation hole on the plug-in section;

[0020] Step 6: Install a hinge on one of the top beams welded in step 2, and connect one side edge of the cover plate in step 3 to the top beam through the hinge;

[0021] Step 7: Install the universal wheel at the bottom of the bottom beam;

[0022] Step 8: Determine the number of hoisting units according to the actual size of the hoisting construction, and repeat steps 1-7 to prepare the remaining hoisting units;

[0023] Step 9: Connect all the lifting units in step 8 to obtain a lifting device.

It can effectively avoid deformation of large-span color steel plates during hoisting and damage during on-site transportation, reduce cutting and welding of color steel plates, save construction costs and shorten construction period.
