Technical field
The utility model relates to a kind of pile foundation test hook, a kind of when doing pile foundation test specifically, for lifting the device field of Steel Reinforcement Cage when especially castinplace pile is tested.
Background technology
Castinplace pile is as a kind of foundation treatment mode, due to friction when it has construction, little without soil compaction, noise, be suitable in advantages such as the intensive area uses of City Building, construction is widely used, castinplace pile is according to the difference of pore-forming technique, it is possible to be divided into dry operation to become the castinplace pile in hole, mud off to become the castinplace pile in hole and the castinplace pile etc. of manually digging hole. But due to different geological conditions and construction environment etc., usually needing to carry out chamber test research correlated performance and application possibility when running into concrete engineering, wherein the experiment process of model groove castinplace pile can be roughly: levelling of the land, deposit starting material, unwrapping wire location, casing are installed, driller insertion, slurrying, Slurry Storage and conveying, start boring, to the whole hole of design elevation, descending reinforcing cage, installation build conduit, inspection, mixing underwater concrete, delivering concrete to groove hole, build mud reclamation.
Castinplace pile is as the primary member of carrying upper load, reinforcing bar plays a part most important, usually there will be Steel Reinforcement Cage when transferring Steel Reinforcement Cage drops at the bottom of hole, the problems such as position skew, at this moment need to put on right position with hook Steel Reinforcement Cage of slinging, existing chamber test draw Steel Reinforcement Cage not facilitate all the time for hanging, mode efficiently, the such as mode of reinforcement welding crescent hook, hook is stretched in hole, rotate crescent hook to make it wale Steel Reinforcement Cage to sling again, the Steel Reinforcement Cage although the method can be sling, but first inconvenient operation, do not hold pulling apparatus easily, it is difficult to force, and device is heavier and is inconvenient to move, moreover the shape of crescent moon hook and subtended angle fix, can not effectively be applicable to the pile foundation of different diameter, the scope of application is narrower, not there is application.
Given this, how conveniently to lift Steel Reinforcement Cage, and the pile foundation being applicable to different diameter requirement needs a problem of solution badly.
Summary of the invention
Main purpose of the present utility model is to provide a kind of pile foundation test hook, and when overcoming lift Steel Reinforcement Cage, safety coefficient is low, inconvenient, is not suitable for the shortcoming of the pile foundation of different diameter.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposals: a kind of pile foundation test hook, comprise mobile jib and it is arranged on the hook of mobile jib end, it is characterized in that described mobile jib is provided with push-pull device, groove, upper metal steel disc, groove described in lower metal steel disc is positioned at mobile jib both sides, described push-pull device card is in a groove, described push-pull device and upper metal steel disc are rigidly connected, the upper end of described upper metal steel disc and two upper rigid connecting rods is rigidly connected, lower end and the lower metal steel disc of two lower rigid connecting rods are rigidly connected, described upper rigid connecting rod is corresponding hinged with lower rigid connecting rod, the tetragon of formation activity, described hook is corresponding with the lower lower end of rigid connecting rod to be fixedly connected with.
Described push-and-pull part comprises fixed part and push-and-pull part, described fixed part comprises union lever and fixed blocks, and described push-and-pull part comprises fixing brace and main part, and main part has card groove, union lever and card groove are flexibly connected, and fixing brace and groove are flexibly connected.
Described mobile jib and handle are rigidly connected.
The useful effect that the utility model reaches:
The convenient lift of the handle that mobile jib top is arranged, push-pull device is as, on groove, can promote forward as required and pull, and fix at any time backward; Four rigid link can realize level, vertical direction moves and rotates, and drives hook closed fully and open, the article of hook pull-up different diameter as required; Conveniently operate and also indirectly improve the safety coefficient in work.
