Problems solved by technology

[0004] If such roof rods are installed by crane, it has the disadvantages of high cost and inconvenient hoisting space.
If such roof rods are installed by welding lugs and manpower pulling, there are disadvantages such as heavy workload of welding and cutting off lifting lugs, welding will cause local damage and deformation of roof beams or purlins, and insufficient lifting space.
[0005] Therefore, there are above-mentioned inconveniences and problems in the hoisting of the known light weight, sporadic distribution and a large number of factory roof rods.

Embodiment 1

[0036] The manual lifting device for hoisting the rods on the roof of the factory of the present invention includes a slotted base, positioning pins and support rods.

[0037] see now figure 1 and figure 2 , figure 1 It is a schematic structural diagram of a manual lifting device according to an embodiment of the present invention, figure 2 for figure 1 A-A sectional view in . As shown in the figure, the slotted base is made of steel plates, including a rectangular upper panel 1, a middle steel plate 2 and a rectangular lower panel 3, and the three steel plates are stacked and welded at one end to form a slot 4; The rectangular upper panel 1 is provided with four through holes 12 arranged at intervals on the opposite side of the welding end; the rectangular upper panel 1 has a length of 341mm and a thickness of 10mm. The rectangular upper panel 3 has a length of 100mm and a thickness of 10mm.

Embodiment 2

[0043] The manufacturing method of the manual hoisting device for hoisting factory roof rods of the present invention is characterized in that it comprises the following steps:

[0044] a. Manufacture of slot-type base: take a rectangular upper panel 1 with a thickness of 10mm, a length of 341mmX and a width of 100mm, and take a hole Φ22mm from one end at a distance of 173mm, 223mm, 273mm, and 323mm from the center of the longitudinal direction; take a thickness of 12mm and a length of 100mmX width 10mm middle steel plate 2, one end of the rectangular upper panel 1 is fully welded to the middle steel plate 2; take a rectangular lower panel 3 with a thickness of 10mm, length 100mm×width 81mm, and one end of the rectangular lower panel is fully welded to the middle steel plate 2; thus, the three steel plates form a card slot form;

[0045] b. Manufacturing of positioning pins: take a M20x60 screw rod, and insert it into different holes for positioning according to the different ...

Abstract

Provided is a manual lifting device used for hoisting factory building roof rod members. The device comprises a clamping groove type base, a positioning pin, and a supporting rod. The device is characterized in that the clamping groove type base is manufactured by steel plates, and comprises a rectangular upper panel (1), an intermediate steel plate (2), and a rectangular lower panel (3). The positioning pin (6) is a M20x60 screw rod. The supporting rod (5) is a seamless steel tube whose [phi] is 38x6 mm and length is 1030 mm. One end of the supporting rod is welded with the position between the welding end of the rectangular upper panel (1) and a hole (12) end. The included angle between the supporting rod (5) and the rectangular upper panel (1) is 70 DEG. A hoisting operating person is on a factory building roof frame and is close to a pulley, and hoists the rod members by pulling a rope (10) by hands. The manual lifting device is advantaged by small volume, light weight, simple structure, convenient manufacturing, easy operation, and flexible use, and is safe and reliable, and saves time and efforts, and greatly improves construction progress.

Description

technical field [0001] The invention relates to a light lifting device for heavy objects, in particular to a manual lifting device for hoisting rods on the roof of a factory. Background technique [0002] During the roof installation of steel structure factory buildings, it is often encountered that due to the mismatch of space or components in some places, rods such as pressure rods, tie rods, horizontal supports, coupler supports, etc. cannot be hoisted in place at the same time as roof beams or purlins. [0003] Baotou Steel’s new system cold-rolled acid-rolled project, roof beams and purlins are all installed in place, and the rods are being installed. Some rods are not hoisted in place at the same time as the roof beams or purlins due to lack of space, hoisting or component processing. Roof rods are generally made of angle steel L50, angle steel L56, and angle steel L63 materials, with a length of 2500mm to 2800mm. This member has the characteristics of light weight, sp...
