Abstract
The utility model discloses a hanging grab, which comprises a rope ring, a supporting cap, an upper sliding box, a rope wheel box, a pulling rod, a bucket box, a square bar, steel wire rope and a locking device, characterized in that two wedge-shaped blocks are welded at the two sides of the position of the square bar waiting for locking by the locking device. An 'L'-shaped clamping jaw is respectively hinged at two sides of a pulley box. The weight of the far end of the clamping jaw is greater than that of the near end and the far end automatically drops downward, and the locking can be achieved by the automatic clamping of the near end in the shoulder of the wedge. In addition, the other end of the extension spring at the two sides of the upper sliding box hangs at the far end of the clamping jaw and the extension spring has a degree of relaxation. The upper sliding box traveling to the position of the supporting cap and pulling the clamping jaw can be guaranteed by the degree of the relaxation, which makes the clamping jaw release the locking. Owing to dual-side clamping jaw, the utility model is vibration proof, and the locking can not be easily released even the great vibration occurs. As the utility model has no wear generated between the contact plane of the clamping jaw and the wedge-shaped block in the running and the automatic releasing can not be caused, the long term normal working of the grab is also ensured.
Description
Technical field
The application belongs to the loading and unloading facility, relates in particular to grab bucket.
Background technology
The open at present suspension type grab bucket that is suitable for all is made up of becket bridle, support cap, upper sliding case, rope sheave case, pull bar, bucket case, Fang Gang, steel rope and closing appliance.Existing closing appliance is a sleeve type spiral closedown mode, and is the single face locking, and this closedown structure is in wear state for a long time, is easy to automatically-unhookedly after the wearing and tearing, also breaks off relations easily when the single face locking is shaken in addition, influences normal operation.
Summary of the invention
The application's purpose is the suspension grab bucket of a kind of difficult unhook of design.
Technical scheme is: existing the suspension on the basis of grabbing bucket closing appliance is improved.The structure of the closing appliance after the improvement is, the both sides, position for the treatment of locking at Fang Gang are welded with wedge-shaped catch, and the both sides in pulley casing are hinged with " L " shape claw, and the far-end weight of claw is greater than near-end weight, far-end drops automatically, near-end is stuck on the convex shoulder of voussoir automatically realizes locking.In addition, hang with tension spring in the both sides of upper sliding case, the tension spring other end hangs over the claw far-end, and tension spring has slackness, when the size of slackness can guarantee that upper sliding case runs to the support cap position claw is spurred, and makes claw take off lock.
Because this closing appliance is two-sided jack catchs type, so be not afraid of vibrations, vibrations severity also is not easy to break off relations; The contact surface of claw and wedge-shaped catch convex shoulder does not does not wear and tear because this structure is in operation again, thus can not cause yet automatically-unhooked, thereby guaranteed the long-term normal operation of grabbing bucket.
Description of drawings
Fig. 1 is the lateral plan of embodiment.
Among the figure: 1--becket bridle, 2--steel rope, 3--support cap, 4--side's thick stick, 5--upper sliding case, 6--tension spring, 7--wedge-shaped catch, 8--clump weight, 9--claw, 10--pull bar, the 11--tank tower that struggles against, the 12--case that struggles against, 13--rope sheave case.
The specific embodiment
As shown in Figure 1, the integral structure of present embodiment and existing suspension grab bucket are basic identical, and it comprises becket bridle 1 and rope sheave case 13, and becket bridle 1 and rope sheave case 13 twine goes up steel rope 2; There is support cap 3 on thick stick 4 tops, side, and square thick stick 4 bottoms are connected on the bucket tank tower 11, and upper sliding case 5 is arranged above the rope sheave case 13, and upper sliding case 5 is by pull bar 10 pulling bucket casees 12 foldings of both sides; Its key is to be welded with wedge-shaped catch 7 at square thick stick respectively near the both sides, bottom, and both sides are connected with claw 9 by hinge in rope sheave case 13, and grab bucket just in time is stuck on wedge-shaped catch 7 convex shoulders when promoting, and the case 12 that prevents to struggle against is opened automatically; Claw 9 far-ends have clump weight 8, guarantee that the far-end tenesmus realizes coupler lock, can not add clump weight when far-end weight is enough; Claw 9 far-ends also have tension spring 6, and pulling spring 6 other ends hang on the upper sliding case 5, and tension spring 6 is a relaxed state when locking, and when sliding on the upper sliding case, tension spring 6 is tightened pulling claw 9 and unblanked, thereby open bucket case 12.
Claims (1)
1, a kind of suspension grab bucket, it comprises becket bridle, support cap, upper sliding case, rope sheave case, pull bar, bucket case, Fang Gang, steel rope and closing appliance, it is characterized in that, described closing appliance structure is:
The both sides, position for the treatment of locking at Fang Gang are welded with wedge-shaped catch, both sides in pulley casing are hinged with " L " shape claw, the far-end weight of claw is greater than near-end weight, and far-end drops automatically, near-end is stuck on the convex shoulder of voussoir automatically realizes locking, in addition, both sides at upper sliding case hang with tension spring, and the tension spring other end hangs over the claw far-end, and tension spring has slackness, when the size of slackness can guarantee that upper sliding case runs to the support cap position claw is spurred, make claw take off lock.
