Abstract

The utility model discloses a compound-lever type self-locking sling used for loading and unloading buckets. The utility model comprises a compound lever increasing power mechanism assembled by a suspended arm, a bracket arm and clamping arms, a spring installed between a bolt and the bracket arm, a random self-locking mechanism assembled by the bolt and locking blocks hinged on the clamping arms and a handle. The utility model has the advantages of strong clamping force of the jaw and safe self-locking mechanism; the jaw can clamp the rim of the bucket firmly no matter the bucket is struck, crashed or hung in the process of swing-up delivery. The compound-lever type self-lock bucket sling is a safe and convenient lifting tool particularly suitable for loading and unloading old buckets.

Description

Compound lever self-lock bucket sling

The utility model is a kind of worker's rigging that the garden barreled unloads that is used for.The hanging element or the device that belong to hoisting crane, capstan, winch and coaster.

The suspender that loads and unloads garden bucket use in the prior art is by jig arm, and trailing arm and bearing pin are formed.It is the deadweight generation gripping power clamping bucket edge mouth to Yun Dong And dependence garden bucket by two jig arm, because the increase and decrease that gripping power is conducted oneself with dignity with the garden bucket changes, garden bucket edge mouth is being held in the palm in the bottom that the jaw on the jig arm must be positioned at outside the bucket edge mouth of garden.Such suspender is anti-lateral impact ability when operation, and to the effectively high requirement of the intact degree of garden bucket edge mouth.When the bucket of the old garden of loading and unloading, such suspender just can not use.Simultaneously owing to structural reason, its gripping power is restricted, even mix self-locking mechanism, bucket is put the storehouse, when putting situation such as car, can be made the garden bucket break away from suspender and cause the accident in the generation garden.

It is big that the purpose of this utility model provides a kind of gripping power, and have auto-lock function at random, easy to use, can be suitable for the harsh environment operation, to garden bucket edge mouth intact require low, the garden Pail lifter that new and old garden bucket all is suitable for.

In order to achieve the above object, solution of the present invention is: compound lever formula force-increasing mechanism is housed on the Pail lifter of garden, it is made up of arm 1, jig arm 2, pull bar 4, trailing arm 8 and bearing

3,5,6,12, and forms a self-locking mechanism at random at the lock dog 11 that dead bolt 10 is equipped with on spring 9 and the jig arm 2 between trailing arm 8.

Technical solution of the present utility model is: arm 1 is installed on the bearing pin 3 with jig arm 2, one end of connecting rod 4 connects by bearing pin 12 and arm 1, the other end connects by bearing pin 5 and trailing arm 8, bearing pin 6 is bound up trailing arm 8 and jig arm 2, can between the dead bolt 10 of the inclined-plane 8 ' slippage of trailing arm 8 and trailing arm 8, spring 9 be housed, the dead bolt 10 that handle 7 is housed contacts with lock dog 11 on the jig arm 2 with suspender work or breaks away from, lock dog 11 is hinged on jig arm 2, and can rotate around the axle center of hinging supporting shaft, handle 7 is hinged with dead bolt 10, and handle 7 can rotate around the hinged place.

Accompanying drawing 1 is stereoscopic figure of the present utility model

Accompanying drawing 2 is operating modes that the utility model clamps garden bucket edge mouth

Accompanying drawing 3 is idle conditions of the present utility model

Most preferred embodiment of the present utility model as shown in Figure 1.Fig. 2 is the operating mode of the utility model clamping garden bucket edge mouth, and it is made up of arm 1, jig arm 2, pull bar 4, handle 7, trailing arm 8, spring 9, dead bolt 10, lock dog 11 and

lock shaft

3,5,6,12.Pull bar 4, jig arm 2, with arm 1, three planes, trailing arm 8 offices.Arm 1 is connected with jig arm 2 by bearing pin 3, and jaw is equipped with in the lower end of jig arm 2.Connecting rod 4 connects with arm 1 and trailing arm 8 respectively by bearing pin 12 and 5.Lock dog 11 is hinged on jig arm 2.And can rotate around the axle center of hinging supporting shaft, guarantee that lock dog 11 can balanced contact with dead bolt 10.Fluted on the trailing arm 8, dead bolt 10 is installed in the groove, and can be along the inclined-plane 8 ' slippage of trailing arm 8.Handle 7 is housed on the dead bolt 10, and handle 7 can be around rotating with the hinged place of dead bolt 10.Between dead bolt 10 and the trailing arm 8 spring 9 is housed, the middle free end of trailing arm 8 is equipped with jaw.During use, the jaw of garden Pail lifter is placed on the edge mouth of garden bucket, arm 1 rotates around bearing pin 3 with the rising of hoisting crane gib head, and drives trailing arms 8 by pull bar 4 and rotate around bearing pin 6, makes jaw sting tight garden bucket edge mouth.In the work of compound lever force-increasing mechanism, dead bolt 10 is under the effect of spring 9, inclined-plane 8 ' downslide along trailing arm 8 contacts with hinged lock dog 11 on jig arm 2, and be stuck in lock dog 11 and trailing arm inclined-plane 8 ' between, make that jig arm 2 and trailing arm 8 can not relative motions, guarantee that jaw tightly bites garden bucket edge mouth all the time in the handling process.When garden bucket handling during to the appointed place, Panasonic's suspender raising line, this moment is because the effect of dead bolt 10, jig arm 2 and trailing arm 8 can not relative motions, the operator only need mention handle 7, and dead bolt 10 and lock dog are broken away from, and jaw also separates with garden bucket edge mouth simultaneously, finish the unloading of suspender, this situation as shown in Figure 3.

The utility model is simple in structure, easy to use, it is big to have a jig jaw clamping force, and self-locking mechanism is safe and reliable, no matter the garden bucket is subjected to any impact, collides and shelve in the handling process, jaw all can firmly be clamped garden bucket edge mouth, particularly more can embody superiority of the present utility model in the handling operation of old garden bucket, when using the utility model, can be according to the needs of handling operation, or two one group, or tetrad, or octette.
