Abstract
The utility model provides a special grapping hook for loading and unloading of concrete curbstone. The special grapping hook comprises two L-shaped hook bodies which are arranged symmetrically, wherein mounting holes are formed in the L-shaped hook bodies, and the L-shaped hook bodies are hinged together through the mounting holes; a positioning plate, perpendicular to a long edge, is arranged on the inner side of a short edge of each L-shaped hook body; a lifting hole is formed in the end part of the long edge of each L-shaped hook body; the interior of the lifting hole is connected with a lifting chain. The special grapping hook is simple in structure, simple and convenient to operate, safe and reliable, saves time and labor, and is applied to loading and unloading, transporting, moving and construction of concrete curbstone with the utilization of the object dead weight and the lever principle; when the special grapping hook is in use, labor intensity is low, manpower is saved, construction speed is accelerated, and construction efficiency and construction quality are greatly improved; the contact surfaces of the grapping hook and an object can be greatly increased through the positioning plates, so that unhooking of the object can be avoided, local stress concentration and scratches of a bright and clean surface can also be prevented, damage to corners of concrete curbstone due to stress concentration can be effectively prevented, and safety and reliability are realized.
Description
Technical field
The utility model belongs to the handling tool technical field, particularly the special-purpose grapple of a kind of concrete road dental calculus loading and unloading.
Background technology
In road building in municipal works and factories and miness zone, the material that has been absolutely necessary of curbstone (kerbstone) on both sides of the road.Because the concrete curbstone (kerbstone) is generally cuboid, every weight is about 60 ~ 100kg, because of every quality heavier, and without loading and unloading, lift part, therefore, carrying is mobile very inconvenient in entrucking, the laying of unloading and construct, labour intensity is large, and operating efficiency is low, and curbstone (kerbstone) occurs often drop and ruin the phenomenon that thing is hurted sb.'s feelings, have larger potential safety hazard.
The utility model content
The purpose of this utility model is to provide the special-purpose grapple of a kind of simple in structure, easy and simple to handle, time saving and energy saving and safe and reliable concrete road dental calculus loading and unloading.
For achieving the above object, the technical solution of the utility model is: the special-purpose grapple of a kind of concrete road dental calculus loading and unloading, comprise two symmetrically arranged L shaped coupler bodies, and L shaped coupler body is provided with mounting hole, and two L shaped coupler bodies are hinged mutually by mounting hole; The minor face inboard of L shaped coupler body is provided with the locating plate perpendicular to long limit, and the end, long limit of L shaped coupler body is provided with lifting hole, is connected with chain sling in lifting hole.
Described chain sling is provided with suspension rod between end, and the suspension rod two ends are provided with hanger, and suspension rod is connected with chain sling by hanger.
Described L shaped coupler body is provided with two mounting holes.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises two symmetrically arranged L shaped coupler bodies, and L shaped coupler body is provided with mounting hole, and two L shaped coupler bodies are hinged mutually by mounting hole; The minor face inboard of L shaped coupler body is provided with the locating plate perpendicular to long limit, and the end, long limit of L shaped coupler body is provided with lifting hole, is connected with chain sling in lifting hole, it is simple in structure, and is easy and simple to handle, time saving and energy saving, safe and reliable, utilize self-weight of object and lever principle, be applied in loading and unloading, carrying movement and the construction of concrete curbstone (kerbstone), in use procedure, labour intensity is low, can save manpower, can accelerate speed of application again, can greatly improve operating efficiency and construction quality; Locating plate can increase the contact surface with object greatly, guarantees that object does not break off relations, and avoids producing stress raisers and smooth surface and the phenomenon of cut occurs, can prevent effectively that stress from concentrating and making the situation of concrete curbstone (kerbstone) corner damage, and is safe and reliable.
2, be provided with two mounting holes on L shaped coupler body, two L shaped coupler bodies are hinged mutually by mounting hole, can adjust the spacing of L shaped coupler body front end by changing the installation site of L shaped coupler body,, with loading and unloading, the carrying that adapts to the different size article, use flexible and convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The special-purpose grapple of concrete road dental calculus loading and unloading as shown in Figure 1, it comprises two symmetrically arranged L shaped coupler bodies 1, be provided with two mounting holes 2 on L shaped coupler body 1, two L shaped coupler bodies 1 are hinged mutually by mounting hole 2, can be by changing the installation site of L shaped coupler body 1, adjust the spacing of L shaped coupler body 1 front end, with loading and unloading, the carrying that adapts to the different size article.Be provided with the locating plate 3 perpendicular to long limit in the minor face inboard of L shaped coupler body 1, can greatly increase the contact surface with object, guarantee that object does not break off relations, and avoid producing stress raisers and smooth surface and the phenomenon of cut occurs, can prevent effectively that stress from concentrating and make the situation of concrete curbstone (kerbstone) corner damage.The end, long limit of L shaped coupler body 1 is provided with lifting hole 4, is connected with chain sling 5 in lifting hole 4, is provided with suspension rod 6 between the chain sling 5 of both sides, and suspension rod 6 two ends are provided with hanger 7, and suspension rod 6 is connected with chain sling 5 by hanger 7.
In the present embodiment, L shaped coupler body 1 adopts the thick Q235 steel plate punched of 6mm to form, and perhaps adopting diameter is round steel or the screw-thread steel of 14 ~ 22mm, through forging, is made into shape as L shaped coupler body 1, and result of use is identical; Locating plate 3 can be selected steel plate or rubber plate.
The utility model utilizes self-weight of object and lever principle, is applied in loading and unloading, carrying movement and the construction of concrete curbstone (kerbstone).In use procedure, save manpower, labour intensity is low, speed of application is fast, safe and reliable, can greatly improve operating efficiency and construction quality.
