Description
Technical field
The utility model relates to a kind of automatic decoupling device, particularly relates to a kind of tripping gear of pile foundation Large strain loading test.
Background technology
Tripping gear is mainly used in pile foundation Large strain loading test, and testing process is as follows: lifting weight, to the height required, then makes weight come off and impact pile foundation instantaneously.Need manually to make weight come off from tripping gear when utilizing existing tripping gear to carry out pile foundation Large strain loading test, manual operation has the following disadvantages: the separating rate of weight and suspension hook is slow; Weight can swing together because of the swing of breaking off relations under manual operation, and the eccentric and labour intensity of operator of weight increases; There is certain risk in manual operation.Therefore the safety and the convenience that improve tripping gear are the technical problems being badly in need of solving.
Summary of the invention
The utility model is intended to solve above-mentioned mentioned technical problem, provides a kind of tripping gear of pile foundation Large strain loading test.
A kind of tripping gear of pile foundation Large strain loading test, it is characterized in that, comprise left jig arm, right jig arm and arm, left jig arm, right jig arm and arm are undertaken hinged by the first bearing pin, the bottom of left jig arm and right jig arm is provided with mutually towards the crotch arranged, and left jig arm, right jig arm are provided with the top of arm the installing hole be connected with hoist cable.
Preferably, arm comprises the first boatswain chair and the first clamping plate be symmetrically set and the second clamping plate, left jig arm and right jig arm to be located between the first clamping plate and the second clamping plate and to be undertaken hinged by described first bearing pin, first boatswain chair is located between the first clamping plate and the second clamping plate and by the second hinge, the first boatswain chair is provided with described installing hole away from one end of the second bearing pin.
Preferably, left jig arm comprises the second boatswain chair and the three-ply board be symmetrically set and the 4th clamping plate, described right jig arm is located between three-ply board and the 4th clamping plate and by described first hinge, the second boatswain chair and described crotch are fixedly arranged on the two ends of three-ply board and the 4th clamping plate respectively.
Preferably, the second boatswain chair and crotch are fixed on the two ends of three-ply board and the 4th clamping plate by welding, riveted joint and/or bolted mode.
Preferably, right jig arm and crotch are formed in one.
Preferably, installing hole is also set with withholds.
Beneficial effect is: the tripping gear of a kind of pile foundation Large strain loading test of the present utility model, and when carrying out pile foundation Large strain loading test, weight unhook is smooth and easy and rapid; Owing to being all the centre being in left jig arm and right jig arm from catching on to weight in the whole process that comes off, process of therefore dropping hammer is steady, landing position is accurate; Do not need artificial unhook, the safety of the personnel that keep the scene intact.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the schematic diagram at a tripping gear visual angle of a kind of pile foundation Large strain loading test of the present utility model;
Fig. 2 is the sectional view at a left jig arm visual angle;
Fig. 3 is the sectional view at an arm visual angle.
Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of tripping gear of pile foundation Large strain loading test, comprise left jig arm 2, right jig arm 3 and arm 1, left jig arm 2, right jig arm 3 and arm 1 are undertaken hinged by the first bearing pin 4, the bottom of left jig arm 2 and right jig arm 3 is provided with mutually towards the crotch 24 arranged, left jig arm 2, right jig arm 3 and the top of arm 1 are provided with the installing hole 6 be connected with hoist cable, each installing hole 6 is set with and withholds, withhold connecting steel wire ropes.
Preferably, the first clamping plate 12 and the second clamping plate 13 that arm 1 comprises the first boatswain chair 11 and is symmetrically set, left jig arm 2 and right jig arm 3 to be located between the first clamping plate 12 and the second clamping plate 13 and to be undertaken hinged by the first bearing pin 4, first boatswain chair 11 to be located between the first clamping plate 12 and the second clamping plate 13 and hinged by the second bearing pin 5, and the first boatswain chair 11 is provided with installing hole 6 away from one end of the second bearing pin 5.First clamping plate 12 and the second clamping plate 13 sandwich left jig arm 2 and right jig arm 3 in one end of the first bearing pin 4, the first boatswain chair 11 is sandwiched in one end of the second bearing pin 5, this set effectively can increase the tensile strength at the first bearing pin 4 place, when tripping gear unblock only has arm 1 to hold weight, arm 1 is not easy fracture; And left jig arm 2 and right jig arm 3 can be rotated around the first bearing pin 4 between the first clamping plate 12 and the second clamping plate 13, and the pulling force holding weight in rotation process can be evenly distributed on the first clamping plate 12 and the second clamping plate 13.
Preferably, left jig arm 2 comprises the second boatswain chair 21 and the three-ply board 22 be symmetrically set and the 4th clamping plate 23, right jig arm 3 to be located between three-ply board 22 and the 4th clamping plate 23 and hinged by the first bearing pin 4, and the second boatswain chair 21 and crotch 24 are fixedly arranged on the two ends of three-ply board 22 and the 4th clamping plate 23 respectively.Second boatswain chair 21 and crotch 24 can be fixed on the two ends of three-ply board 22 and the 4th clamping plate 23 by welding, riveted joint and/or bolted mode.Right jig arm 3 and crotch 24 are formed in one.The three-ply board 22 of left jig arm 2 and the 4th clamping plate 23 one end sandwich crotch 24, the other end sandwiches the second boatswain chair 21, this set effectively can increase the tensile strength of left jig arm 2, when tripping gear is in lockup state, the pulling force holding weight can be evenly distributed on three-ply board 22 and the 4th clamping plate 23.
The operating principle of the tripping gear of a kind of pile foundation Large strain loading test of the present embodiment is as follows: during weight lifting, while wire rope in left jig arm 2 and right jig arm 3 pulls left jig arm 2 and right jig arm 3, the crotch 24 of left jig arm 2 and right jig arm 3 lower end can be withstood mutually, thus the wire rope firmly clamped on the wire rope arm 1 holding weight, the wire rope on arm 1 is in relaxed state when weight lifts by crane; After weight is lifted to and requires height, the wire rope on fixing arm 1 also makes the steel wire rope looseness in left jig arm 2 and right jig arm 3, and now arm 1 is stressed, and crotch 24 is thrown off automatically, and weight falls rapidly.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
