Abstract
The utility model discloses a dedicated lifting hook of H-shaped steel, which belongs to the technical field of lifting tools and is used for rapidly, conveniently and safely lifting the H-shaped steel. The technical scheme of the utility model is as follows: the dedicated lifting hook is composed of a steel lifting lug and a steel hook body, wherein the hood body is of a U shape, one side hook of the U-shaped hook body is inclined outwards, the other side hook of the U-shaped hook body is vertical to a bottom edge, the distance of a U-shaped opening is larger than the width of a U-shaped bottom edge, the lifting lug is connected to the end part of the side hook which is inclined outwards, of the U-shaped hook body, the cross section of the U-shaped hook body is of an H shape, and H-shaped grooves are arranged at two sides of the U-shaped hook body. The dedicated lifting hook of the H-shaped steel, disclosed by the utility model, has the advantages of being light and firm in structure, low in cost, very easy to insert into a superposed H-shaped steel bunch when in loading and unloading and not easy to cause unhooking, and eliminating potential unsafety hazards; and the dedicated lifting hook also has the advantages of being convenient, fast, safe and reliable when being used for loading and unloading goods, reducing labor intensity of a worker, lowering the production cost, and simultaneously greatly increasing the working efficiency.
Description
Technical field
The utility model relates to a kind of special hanger of the H of lifting shaped steel, belongs to the lifting device technical field.
Background technology
H shaped steel is called " worker " word steel again; Be the important steel that various large-scale plants such as crane facility, bridge construction, train, large-sized boiler, weighing apparatus parts use; At the harbour, the volume of goods loaded and unloaded of steel point of transhipment such as Railway station, goods yard is very big; Bundled H shaped steel specification is many, and length is generally about 12m, and is that have even longer.In the loading and unloading of H shaped steel, the loading and unloading requirements for quality is very high, therefore load and unload difficulty big, dangerous high, handling efficiency is low.The handling technology of tradition H shaped steel adopts snag to buckle the pocket hoisting, and promptly elevator machinery is joined the operation of snag knotted rope tool with a thick stick chain, and the workman penetrates one on snag button bottom H shaped steel, and snag is hung on the button nose, thereby H shaped steel is steadily hung the appointed place.When the snag knotted rope hung, steel rope was very big to the application force of H shaped steel, and H shaped steel wing plate edge is extremely sharp; Serious to steel rope abrasion, make steel rope very easily fracture of wire, disconnected thigh, according to measuring and calculating; 1000 tons of H shaped steel of every loading and unloading need be scrapped 20 steel ropes, are worth to be about 3800 yuan, thereby have increased shipping and delivery cost.Simultaneously, use the snag button to take out the hook operation and cause goods damage easily, also improved productive costs.Adopt traditional hanging method aspect safety in production, also to have very big problem, constitute bigger threat, when H shaped steel is taken out the hook operation, roll easily simultaneously, be prone to injure by a crashing object the workman, have very big potential safety hazard like wire cable rupture, damaged workman to operation.
The utility model content
The utility model technical matters to be solved provide a kind ofly overcome snag button serious wear that existing lifting device exists, danger coefficient is big, shipping and delivery cost is high, H shaped steel is prone to roll defectives such as hurting sb.'s feelings H shaped steel suspender.
The technical scheme that solves the problems of the technologies described above is:
The special-purpose suspension hook of a kind of H shaped steel, it is made up of hanger and coupler body, and coupler body is the U type; One side hook of U type coupler body is outward-dipping; The opposite side hook is vertical with the base, and the distance of U type opening is greater than the width on U-bottom limit, and hanger is connected the end of the outward-dipping side hook of U type coupler body; The cross section of U type coupler body is an I shape, and the groove of I shape is positioned at the both sides of U type coupler body.
The special-purpose suspension hook of above-mentioned H shaped steel; The length of the side hook vertical with the base of said U type coupler body is 140-160mm; The A/F of U type coupler body is 110-140mm, and the angle between the mid point of the vertical side hook of the center of circle of hanger center hole for hoist and U type coupler body is 55 °-65 °.
The special-purpose suspension hook of above-mentioned H shaped steel, the vertical side of said U type coupler body is hooked in has tapering on the length direction, and the width of chimoto is less than the width of hook bottom, and tapering is 2:3.
The special-purpose suspension hook of above-mentioned H shaped steel, the groove dual-side of the diameter edge of said hanger center hole for hoist and the i shaped cross section of U type coupler body is tangent.
The usefulness of the utility model is:
The utility model is not only simple in structure light and handy, solid firm, cheap, and in the loading and unloading H shaped steel that the time can be easy to inject stack ties, not only is difficult for causing unhook, has also eliminated hidden danger; When handling goods, not only convenient and swift, safe and reliable, and reduced working strength of workers, and also reduced productive costs, also improved work efficiency simultaneously greatly.
Description of drawings
Fig. 1 is the stereoscopic-state figure of the utility model;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the running condition figure of the utility model.
Mark is following among the figure: hanger 1, groove 2, coupler body 3, hole for hoist 4, steel rope 5, snap ring 6, H shaped steel 7, angle β, width h, length L.
The specific embodiment
The utility model is made up of with coupler body 3 hanger 1 of steel.
Show among the figure that coupler body 3 is the U type, a side hook of U type coupler body 3 is outward-dipping, and the opposite side hook is vertical with the base, and the distance of U type opening is greater than the width on U-bottom limit, and the cross section of U type coupler body 3 is an I shape, and the groove 2 of I shape is positioned at the both sides of U type coupler body 3.I shape is processed in coupler body 3 cross sections, can reduce the coupler body deadweight, improves antitorque, the bending strength of coupler body.
The vertical side of U type coupler body 3 is hooked in has tapering on the length direction, the width of chimoto is less than the width of hook bottom, and tapering is 2:3.The vertical side hook has tapering, and the scope of operation is filled in the H shaped steel hole of stack easily.
Show among the figure that hanger 1 is connected the end of U type coupler body 3 outward-dipping side hooks, groove 2 dual-sides of the i shaped cross section of the diameter edge of hanger 1 center hole for hoist 4 and U type coupler body 3 are tangent.When processing hole for hoist 4, for increasing the area of contact of snap ring axle and hole for hoist 4, the diameter of hole for hoist 4 and groove 2 are tangent, thereby increase area of thrust surface.
Show among the figure; Through many times testing, calculating; The optimum structure of the utility model is: the length L of the side hook vertical with the base of U type coupler body 3 is 140-160mm; The A/F H of U type coupler body 3 is 110-140mm, and the angle β between the mid point of the vertical side hook of the center of circle of hanger 1 center hole for hoist 4 and U type coupler body is 55 °-65 °.
For reducing stress concentration, the bending part of the utility model coupler body 3 is avoided the right angle as far as possible and is adopted arc transition, also avoids the right angle that ankle injury is caused on the goods surface simultaneously.
