Description

A kind of building ground safety hook device
Technical field
A kind of building ground of the utility model safety hook device, relates to a kind of safety hook device using on building ground, belongs to Architectural Equipment field.Be particularly related to and a kind ofly when the aloft work of building ground, use, can prevent that suspension hook is separated with building materials, and workman accesses the safety hook device of building materials required time can effectively reduce aloft work time.
Background technology
The most of high-altitude suspension hook using in building ground at present, during lifting heavy, suspension hook structure is not shut, weight is easily separated in the aerial generation of height with suspension hook, easily produces industrial accident, and a part has the high-altitude suspension hook of enclosuring structure, because the design of enclosuring structure and high-altitude suspension hook is unreasonable, be not easy to workman fast that suspension hook is separated with building materials, while accessing building materials, length expends time in, and sometimes must a plurality of workmans cooperatively interact, could be safer access building materials.
Summary of the invention
In order to improve above-mentioned situation, a kind of building ground of the utility model safety hook device provides a kind of and has used when the aloft work of building ground, can prevent that suspension hook is separated with building materials, and workman accesses the safety hook device of building materials required time can effectively reduce aloft work time.
A kind of building ground of the utility model safety hook device is achieved in that a kind of building ground of the utility model safety hook device is comprised of automatic switch device and engine installation two parts.Automatic switch device is by bolt, main hook part, opening and closing grab and sliding tray forms, opening and closing grab is placed in main hook part by bolt, sliding tray is placed in and opens and closes on grab, engine installation is by hanging the arm of force, touch fixture block, Compress Spring, sliding shoe, drive link, horizontal slot, driving groove, pretective sleeve pipe, bolt of rear end plate and fixture block chute form, the hanging arm of force is placed in main hook part, pretective sleeve pipe is fixed on the hanging arm of force by bolt of rear end plate, driving groove is placed in main hook part, horizontal slot is placed on driving groove, touching fixture block is stuck on pretective sleeve pipe by fixture block chute, sliding shoe is placed in sliding tray, drive link one end is connected with sliding shoe with driving groove through horizontal slot successively, touch fixture block and be placed in the drive link other end, Compress Spring is around being placed on drive link, and touching between fixture block and horizontal slot.
During use, the hanging arm of force is connected with tower crane rope, main hook part catches on the steel rope on the building materials transport trolley that needs transportation, now steel rope presses switching grab afterbody, opening and closing grab will rotate centered by bolt, and then drive drive link to move downward along driving groove by sliding shoe, drive link drives shake-up fixture block to be stuck in fixture block chute and moves downward, steel rope falls into behind main hook part inside, drive link is under the effect of Compress Spring, drive sliding shoe upward movement, sliding shoe by sliding tray drive open and close grab in main hook part centered by bolt moving, and then make steel rope be enclosed in main hook part and open and close upwards lifting between grab, when needs access building materials, first with one, hold pretective sleeve pipe, with thumb, press shake-up fixture block downwards, touch fixture block under the effect of Compress Spring, touching fixture block down moves along fixture block chute, touching fixture block drives sliding shoe to move downward by drive link, sliding shoe by sliding tray drive open and close grab in main hook part centered by bolt moving, open and close between grab and main hook part and form hole, steel rope can easily form hole and take out from opening and closing between grab and main hook part, reach when the aloft work of building ground and use, can prevent that suspension hook is separated with steel rope, and in the time of can effectively reducing aloft work, workman accesses the object of building materials required time.
Beneficial effect
One, simple in structure, convenient and practical.
Two, with low cost, be easy to promote.
Three, in the time of can effectively reducing aloft work, workman accesses building materials required time.
Accompanying drawing explanation
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of building ground of the utility model safety hook device
In accompanying drawing
Wherein part is: the hanging arm of force (1), touches fixture block (2), Compress Spring (3), drive link (4), driving groove (5), sliding shoe (6), bolt (7), main hook part (8), opens and closes grab (9), sliding tray (10), horizontal slot (11), fixture block chute (12), pretective sleeve pipe (13), bolt of rear end plate (14).
