Abstract
The invention discloses a turnover lifting hook. The turnover lifting hook comprises a lifting hook body, and further comprises a T-shaped clamping groove formed in the lower part of the lifting hook body and a lifting hole formed in the upper part of the lifting hook body; the lifting hook body is rotationally provided with one end part of a baffle plate for stopping a clamping port of the T-shaped clamping groove; and a locking mechanism for locking the the other end part of the baffle plate and the lifting hook body is arranged between the two. The turnover lifting hook is simple in structure, easy to be machined, applicable and portable, improves the turnover efficiency of H-shaped steel in the machining process, saves the labor hour, is safe in use, and greatly improves the operation safety coefficient of constructors.
Description
Technical field
The present invention relates to a kind of turning lifting hook.
Background technology
" H " shaped steel is that a kind of section area distribution is optimized more, the more rational economic section high efficiency section bar of the ratio of strength to weight, gain the name because its section is identical with English alphabet " H ", " H " shaped steel material is widely used, in large H-shaped steel material makes, for ensureing welding quality, improve welding efficiency, avoid taking overhead welding as far as possible, the mode of vertical position welding is welded, so usually needing that in the process made H profile steel material is carried out repeatedly upset to avoid the operation of above-mentioned welding process, but present stage adopts common Current Collector Sleave usually, as H profile steel material is overturn by card hook, operation has upset difficulty like this, operational danger.
Summary of the invention
It is an object of the invention to overcome in prior art the defect existed, it is provided that a kind of turning lifting hook that can be overturn by H profile steel material safely, easily.
For achieving the above object, the technical scheme of the present invention there is provided a kind of turning lifting hook, comprise hook body, also comprise the T-shaped card groove being opened in described hook body bottom, be arranged at described hook body top hang hole, described hook body is rotated the one end of the baffle plate being provided with the bayonet socket for blocking T-shaped card groove, it is provided with the lockout mechanism of both lockings between the other end of described baffle plate and described hook body, described hole of hanging at least is provided with two, described hole of hanging has three, one of them is positioned on the plummet at center of gravity place of described hook body, two other lays respectively at the both sides of described plummet.
As preferably, described T-shaped card groove is set to the inclined-plane of inclination downwards by described bayonet socket to both sides.
As preferably, described hanging is provided with web member in hole.
Advantage and the useful effect of the present invention are: structure is simple, easily processes, and are suitable for portable, it is to increase to the upset efficiency of H profile steel material in the course of processing, save man-hour, it may also be useful to safety, substantially increases the operational safety coefficient of workmen.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1, hook body; 2, T-shaped card groove; 3, inclined-plane; 4-1,4-2,4-3, hang hole; 5, baffle plate; 6, web member; 7, web; 8, flange plate.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described. Following examples are only for clearly illustrating the technical scheme of the present invention, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of turning lifting hook, comprise hook body 1, the top also comprise the T-shaped card groove 2 being opened in described hook body 1 bottom, being arranged at described hook body 1 hang hole 4-1,4-2,4-3, described hook body 1 is rotated the one end of the baffle plate 5 being provided with the bayonet socket for blocking T-shaped card groove 2, is provided with the lockout mechanism of both lockings between the other end of described baffle plate 5 and described hook body 1.
Lockout mechanism is not the protection main points of the present invention, as long as can be used at this by the lockout mechanism that two parts lock mutually.
The longitudinally part of described T-shaped card groove 2 is shorter, and its width is a bit larger tham the width of the web 7 of " H " shaped steel material; The lateral part size of described T-shaped card groove 2 and H " flange plate 8 size of shaped steel material is suitable, and the size being namely greater than flange plate 8 is about 3mm ~ 5mm.
Described hang hole 4-1,4-2,4-3 have three, and on one of them plummet being positioned at the center of gravity place of described hook body 1, two other lays respectively at the both sides of described plummet.
Described T-shaped card groove 2 is set to the inclined-plane 3 of inclination downwards by described bayonet socket to both sides. The effect on described inclined-plane 3 in avoiding the stupefied existence of force part square edge, thus avoid H profile steel material to produce stress in lifting umklapp process and concentrate and cause tearing.
Described hanging is provided with web member 6 in hole 4-1,4-2,4-3. Described web member 6 is normally used U-shaped snap ring, is connected with lifting machine etc., so more not easily produces obscission.
During use, only need to the turning lifting hook that match with H profile steel material be arranged on the flange plate 8 of steel, then baffle plate 5 is blocked the bayonet socket place of T-shaped card groove, prevent steel slippage in the process of lifting, then lifting machine is fixed on and hangs hole 4-1 accordingly,, hang hole 4-2, hang on the 4-3 of hole, the upset to H profile steel material and lifting can be realized, when wanting to overturn clockwise, by lifting machine, hole 4-1 fixes with hanging, and when needs overturn counterclockwise, by lifting machine, hole 4-3 fixes with hanging, when lifting machine, hole 4-2 fixes with hanging, it is possible to directly sling by H profile steel material.
The above is only the preferred embodiment of the present invention; it is noted that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
1. a turning lifting hook, comprise hook body, it is characterized in that: also comprise the T-shaped card groove being opened in described hook body bottom, be arranged at described hook body top hang hole, described hook body is rotated the one end of the baffle plate being provided with the bayonet socket for blocking T-shaped card groove, it is provided with the lockout mechanism of both lockings between the other end of described baffle plate and described hook body, described hole of hanging at least is provided with two, described hole of hanging has three, one of them is positioned on the plummet at center of gravity place of described hook body, two other lays respectively at the both sides of described plummet.
