Abstract
The utility model relates to a hoisting clamp for concrete block blanks. The hoisting clamp for concrete block blanks is composed of seven parts, namely a movable clamping plate, a stress arm plate, a vertical positioning plate, a limiting rod, a hoisting chain, a falling-prevention plate and bolts, wherein the design of the limiting rod and the movable clamping plate guarantees that the whole clamp can automatically enter a hoisting device through the self weight, the vertical positioning plate guarantees the vertical distance of a hoisting point, the concrete block blanks of various specifications can be hoisted by replacing the limiting rod, the whole structure can be connected through the bolts, the structure is simple, operation is convenient, and cost is low. The hoisting clamp for concrete block blanks resolves the technical problems that an existing hoisting clamp is too simple or complex in structure and unreasonable in labor intensity and machining cost, wastes time and labor and is too low in work efficiency.
Description
Technical field
The utility model relates to a kind of lifting device of concrete segment, particularly a kind of concrete segment blank fixture for lifting.
Background technology
In building and production of construction materials field, because the deadweight of concrete segment blank is larger, usually need to use crane that its handling to appointed place is processed and installs.On market, existing stone tongs mainly contains two kinds, and a kind of simple structure can not be opened by the arm of force automatically, must carry out human assistance operation, inefficiency; The second adopts hydraulic efficiency gear, and structure is comparatively complicated, not only heaviness but also increased tooling cost.
The utility model content
The purpose of this utility model is to provide a kind of concrete segment blank stone tongs, and the structure that solves existing lifting device existence is too simple or complicated, and labour intensity and tooling cost are unreasonable, and the extremely low technical matters of work efficiency wastes time and energy.
For achieving the above object, the utility model adopts following technical scheme:
A kind of concrete segment blank stone tongs, comprise ambulatory splint, be subject to arm board, the perpendicular positioning plate, position-limited lever, the lifting chain, anticreep plate and bolt, the described arm board that is subject to is two strip metal plates that band bends and is oppositely arranged, two are subject to the bottom of arm board to be hinged with respectively two ambulatory splints that can rotate freely by the clamping plate pad, two are subject to the middle part of arm board to be connected with the perpendicular positioning plate of level by hinged vertical link, two are subject to the top of arm board to be fixed with the position-limited lever of a level by bolt and anticreep plate, two lifting chains that connected by top by arm board are connected with the suspension hook of lifting appliance.
Describedly be subject on arm board, with the hinged place of ambulatory splint, be provided with the spacing pad that is connected of ambulatory splint.
The two ends of described position-limited lever are provided with waist shaped hole, bolt by waist shaped hole by position-limited lever be connected by arm board.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model carries out the lifting scope by position-limited lever to fixture and clamps the adjusting of angle, by the perpendicular positioning plate, to clamping, highly positions, and has guaranteed the reasonableness of building block clamped position.
Ambulatory splint in the utility model relies on slewability and the fixture deadweight of self, when fixture touches the building block blank edge, can automatically open, and guarantees that building block enters the lifting scope smoothly, has reduced labour intensity, has reduced recruitment quantity, has improved work efficiency.
Connection between the utility model member is all with bolts, and simple structure is simple to operation, meets building block blank lifting demand.

Reference numeral: 1-ambulatory splint, 2-are subject to arm board, 3-perpendicular positioning plate, 4-position-limited lever, 5-lifting chain, 6-anticreep plate, 7-bolt, 8-connecting rod, the spacing connection pad of 9-, 10-concrete segment blank, 11-clamping plate pad, 12-waist shaped hole.
The specific embodiment
Embodiment is referring to shown in Fig. 1,4～8, a kind of concrete segment blank stone tongs, comprise ambulatory splint 1, be subject to arm board 2, perpendicular positioning plate 3, position-limited lever 4, lifting chain 5, anticreep plate 6 and bolt 7, the effect of anticreep plate 6 is to prevent that position-limited lever 4 breaks away from bolts 7.The described arm board 2 that is subject to is two strip metal plates that band bends and is oppositely arranged, two are subject to the bottom of arm board 2 to be hinged with respectively two ambulatory splints that can rotate freely 1 by clamping plate pad 11, two are subject to the middle part of arm board 2 to be connected with the perpendicular positioning plate 3 of level by hinged vertical link 8, the vertical distance that 3 pairs of fixtures of perpendicular positioning plate enter gripping range positions, assurance steps up position reasonableness a little, two are subject to the top of arm board 2 to be fixed with the position-limited lever 4 of a level by bolt 7 and anticreep plate 6, two lifting chains 5 that connected by top by arm board 2 are connected with the suspension hook of lifting appliance, the discontinuity of avoiding being rigidly connected and causing.
Describedly be subject on arm board 2, with the hinged place of ambulatory splint 1, be provided with the spacing pad 9 that is connected of ambulatory splint 1, its objective is and prevent that its anglec of rotation is excessive.
Described position-limited lever 4 two ends be provided with waist shaped hole 12, can to the opening angle of fixture, be adjusted within the specific limits, bolt 7 by waist shaped hole 12 by position-limited lever 4 be connected by arm board 2.
Using method of the present utility model is as follows:
Shown in Fig. 2-3, the utility model is the dead weight that relies on fixture, make and automatically opened by arm board 2, guarantee that fixture enters clamped position smoothly, guarantee to be subject to the arm board Automatic-clamping simultaneously, and limit its opening angle by position-limited lever 4, and realize that ambulatory splint 1 enters the gripping range of concrete segment blank 10 automatically, the perpendicular positioning plate is realized location to the vertical distance of fixture.
The utility model provides a kind of structure simple and direct, easy to operate, and the fixture that relies on mechanical property to be lifted, reduced labour intensity and tooling cost, improved work efficiency.
