Description

Be used for the automatic decoupling device that a machine hangs stake

Technical field

The utility model relates to and is used for the tripping gear that a machine hangs stake.

Background technology

In builing industry very flourishing today, the hammering stake has obtained using widely, and in the work progress of hammering stake, a stake machine hang stake to assigned address and as early as possible unhook be an important procedure.If after adding " mousing-hook safeties " this mode and feed good stake with C shape hook, can't be automatically-unhooked, could break off relations after having only the people to climb to the high-altitude, do not only time-consumingly but also require great effort like this, be impracticable basically in the practice of construction.So C shape hook commonly used does not now add " mousing-hook safeties ", just C shape hook is tied down stake by wire rope, so just has certain potential safety hazard.

The utility model content

The purpose of this utility model is to provide a kind of automatic decoupling device that a machine hangs stake that is used for, and this tripping gear is simple in structure, easy to operate, safety.

The utility model is achieved in that a kind of automatic decoupling device that a machine hangs stake that is used for, comprise buckle, movable iron bolt, steel bushing, cover plate, seizing wire, spring, buckle is a U-shaped, can hold hook in the U-shaped, the fixedly connected steel bushing of buckle one end, be set with spring and movable iron bolt in the steel bushing, the afterbody of movable iron bolt is being pressed spring, the head of movable iron bolt stretches out steel bushing and heads on the buckle U-shaped other end outward, and the afterbody of movable iron bolt is equipped with seizing wire, at the afterbody of steel bushing cover plate is housed, and cover plate and steel bushing are for being threaded, have the hole on the cover plate, seizing wire passes cover board hole and stretches out outside the steel bushing.

Described tripping gear also comprises block, has through hole in the buckle U-shaped other end, matches with the external diameter of movable iron bolt in this hole, and block is equipped with in the outer end in hole.

The utility model is on the basis of existing C shape suspension hook, by between C shape suspension hook and wire rope that stake is tied down, tripping gear being housed, by tripping gear wire rope is separated with suspension hook, thereby simplified the operation of breaking off relations, and tripping gear is simple in structure, people and far away, easy to operate, the safety of suspension hook distance, time is short, has improved efficiency of construction.

Description of drawings

Fig. 1 is used for the automatic decoupling device structural representation that a machine hangs stake for the utility model;

Fig. 2 is used for the automatic decoupling device user mode schematic diagram that a machine hangs stake for the utility model.

Among the figure: 1 hook, 2 buckles, 3 movable iron bolts, 4 steel bushings, 5 seizing wires, 6 fasten the wire rope (wire rope) of hanging object, 7 springs, 8 blocks, 9 cover plates.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, a kind of be used for a machine hang the stake automatic decoupling device, comprise buckle 2, movable iron bolt 3, steel bushing 4, cover plate 9, seizing wire 5, spring 7, buckle 2 is a U-shaped, can hold hook 1 in the U-shaped, the fixedly connected steel bushing 4 of buckle 2 one ends, be set with spring 7 and movable iron bolt 3 in the steel bushing 4, the afterbody of movable iron bolt 3 is being pressed spring 7, and the head of movable iron bolt 3 stretches out outside the steel bushing 4 and heads on the buckle 2 U-shaped other ends, and the afterbody of movable iron bolt 3 is equipped with seizing wire 5.Afterbody at steel bushing 4 is equipped with cover plate 9, and cover plate 9 and steel bushing 4 have the hole for being threaded on the cover plate 9, and seizing wire 5 passes cover plate 9 holes and stretches out outside the steel bushing 4.

Having through hole in the buckle 2 U-shaped other ends, matches with the external diameter of movable iron bolt 3 in this hole, and block 8 is equipped with in the outer end in hole, passes buckle 2 in order to stop the movable iron bolt 3 under spring 7 power effects.

Can have the hole in the buckle 2 U-shaped other ends, this hole is not a through hole yet, matches with the external diameter of movable iron bolt 3 in this hole, and movable iron bolt 3 enters this hole under spring 7 power effects, and so movable iron bolt 3 pins buckle 2.

The course of work of the utility model tripping gear is as follows:

Referring to Fig. 2, hook 1 passes in buckle 2 U-shapeds tripping gear is sling, and movable iron bolt 3 is inserted in and ties down the wire rope 6 that is hung stake, under the effect of hook 1 stake is hung toward assigned address; Stake is promptly inserted in the soil by weight hammering one or two hammer back first segment stakes fully, at this moment operating personnel's seizing wire 5 of holding tripping gear draws back movable iron bolt 3, movable iron bolt 3 is pulled back in the steel cylinder cover 4, tie down the wire rope 6 disengaging activity iron bolts 3 that hung stake, hook 1 and stake are broken away from, finish the operation of breaking off relations.After unclamping seizing wire 6, movable iron bolt 3 rebounds under spring 7 power effects and withstands the buckle 2 U-shaped other ends, and tripping gear returns back to original state.Under the traction of hook 1, carry out next pile lifting, unclamp operation.

The utility model is simple in structure, easy to operate, safety, efficiency of construction height.
