Description

Technical Field

[0001] The utility model relates to the technical field of grey cast iron profiles, in particular to a special hoisting fixture for grey cast iron profiles. Background Art

[0002] Gray cast iron is a type of cast iron. Carbon exists in cast iron in the form of flake graphite. The fracture is gray. It has good casting and cutting performance and good wear resistance. It is used to manufacture racks, boxes, etc. Gray cast iron graphite is flake-shaped, with a relatively small effective bearing area, and stress concentration is easy to occur at the tip of graphite, so the strength, plasticity and toughness of gray cast iron are lower than other cast irons. However, it has excellent vibration damping, low notch sensitivity and high wear resistance. When using it, it needs to be hoisted with lifting equipment.

[0003] However, the existing lifting devices have certain defects in actual use. When lifting and clamping, some of them are clamped and lifted by the side panels. Although it is convenient to clamp, the stability is relatively poor during movement. Some of them can lift the bottom to ensure safety during lifting, but it is not convenient to clamp during placement and lifting. Utility Model Content

At the same time, it can be positioned and fixed after adjustment. Fastening bolts 18 are engaged with threads on both sides of the card block 6, which can be tightened and fixed to the side panel 2 after adjustment. Electric push rods 15 of the auxiliary mechanism are installed inside the two sides of the mounting plate 11, and a positioning device is provided between the two electric push rods 15 on the same side. Plate 10, two groups of connecting rods 16 (or three or four groups) are welded on the side walls of the two positioning plates 10 that are close to each other, and the ends of the connecting rods 16 are provided with fixing blocks 13 by means of rotating balls 17, and the side walls of the fixing blocks 13 are bonded with anti-skid pads 14, which can conveniently clamp the sides of the gray cast iron profiles, and at the same time, fine-tune the rotation according to the surface shape to ensure the clamping effect, and an electromagnet 12 (mainly composed of an energized coil and an iron core, etc., which is a relatively mature technology and will not be described here) is also installed at the bottom of the mounting plate 11, which can conveniently power on the gray cast iron profiles for auxiliary attraction during clamping to ensure the clamping effect, and power off during placement to facilitate placement.

[0024] See also Figure 1-Figure 5 In order to facilitate the clamping and lifting of the middle part of the gray cast iron profile, avoid the situation of falling off during the lifting and moving process, and ensure stability and safety, an adjustment groove 19 (whose cross-sectional shape can be T-shaped) of the adjustment component is opened inside the base plate 1, and an adjustment block 21 is slidably arranged inside the base plate 1 through a two-way telescopic rod 20, and a clamping plate 7 of a clamping mechanism is welded at the bottom end thereof, which can conveniently bring the clamping plate 7 closer and farther from each other, and facilitate the clamping operation.
