Description

Self-locking type lifting hook of crane

Technical Field

The utility model relates to a jack-up lifting hook technical field, concretely relates to hoist is from locking-type lifting hook.

Background

The lifting hook, known by the english name lifting hook, is the most common type of spreader in lifting machinery. The hook is often suspended on a steel wire rope of the hoisting mechanism by means of a pulley block and the like; the existing lifting hook in the market is divided into a single hook and a double hook, and for safety and convenience, a spring lock is also usually arranged on the lifting hook, the opening of the lifting hook is blocked through a spring, when a large-scale object is lifted, only a ground operator seals and locks the opening of the lifting hook, the large-scale object is kept away, and a crane can lift the large-scale object, so that the working efficiency of the crane is increased due to the fact that the blocking of the spring lock can greatly reduce the unhooking condition of the lifting hook, and the working safety of the crane is improved.

However, the crane hook in the application process has the following defects and shortcomings: the spring lock on the crane hook can effectual increase security performance and work efficiency, but the spring lock of lifting hook also can be because folding in to the lifting hook when using, can reset smoothly in order to guarantee the spring lock to must reduce the object surface area who passes the lifting hook, when the object surface area who passes the lifting hook is too big, can appear not getting into or can not get out the problem of hook, and this availability factor that is unfavorable for the lifting hook.

SUMMERY OF THE UTILITY MODEL

Example (b):

the utility model discloses a hoist is from locking-type lifting hook, refer to 1-4: including coupler body 1 and hasp 2, coupler body 1 is close to the assembly pulley end and is provided with first shaft hole 3 and slide opening 4, hasp 2 includes dead lever 6, axostylus axostyle 7 and bracing piece 8, dead lever 6 is close to assembly pulley one end and is provided with second shaft hole 9, sliding fit has axostylus axostyle 7 in the second shaft hole 9, axostylus axostyle 7 passes first shaft hole 3 and second shaft hole 9, 7 both ends of axostylus axostyle all are provided with screw thread 10, screw thread 10 department is provided with complex bolt 11 with it, bracing piece 8 is close to the assembly pulley terminal surface and passes through axis of rotation 12 with dead lever 6 and articulate, sliding fit has slider 13 in the slide opening 4.

Wherein, the hook body 1 is also fixedly connected with a circular ring 14 near the end surface of the pulley block; the device can be connected with the pulley block through the circular ring 14, so that the device is in a working state.

The slide hole 4 and the slide block 13 are T-shaped, two slide blocks 13 are arranged, and the opposite surfaces of the two slide blocks 13 are connected with each other through an elastic piece 15; through the cooperation of T type slide opening 4 and slider 13 and elastic component 15 to make slider 13 can bounce or press down, and then realize the auto-lock.

The number of the support rods 8 is two, and the end face, far away from the fixed rod 6, of each support rod 8 is fixedly connected with an arc-shaped block 16; through the arc-shaped block 16, when the device hooks an object, the object can press the arc-shaped block 16, and then the fixing rod 6 descends to seal the opening of the hook body 1 to form self-locking.

The number of the fixing rods 6 is two, and the fixing blocks 5 are fixedly connected to the end faces, far away from the shaft lever 7, of the fixing rods; through fixed block 5 to realize

fixed block

5 and 1 hook point department friction fit of coupler body, and then when making coupler body 1 take place elastic deformation, the dead lever 6 still fixes the closure and pins 1 opening part of coupler body, and then has reduced the risk of unhooking.

Wherein, the first shaft hole 3 comprises two collars 17, a torsion spring 18 is arranged between the two collars 17, and the shaft rod 7 passes through the two collars 17 and the torsion spring 18; the torsion spring 18 is matched with the shaft lever 7, so that the fixing rod 6 is always in an open state when the device is in a non-working state, and the fixing rod 6 can be reset through the torsion spring when hooking is finished.

The working principle is as follows: when the device is required to work, firstly the device is moved to an accessory needing to hook an object, then the fixed rod 6 is lifted to enable the fixed rod to be far away from the hook tip part of the hook body 1 to reduce the influence on the opening area of the hook body 1, then the object needing to be hooked is placed into the hook body 1, then the fixed rod 6 is put down, then the fixed frame 6 needs to be released to reset, or the device is pulled to enable the hook body 1 to move upwards relative to the supporting rod 8, at the moment, the arc-shaped block 16 is gradually close to the hook groove of the hook body 1 under the downward pressing of the object, when the arc-shaped block 16 is in friction contact with the hook body 1, the fixed rod 6 passes through the sliding block 13 (preferably, the two sides of the sliding hole 4 are both provided with baffles, one side of which can be dismounted through the threads), when the fixed block 6 completely passes through the sliding block 13, the sliding block 13 is bounced to limit the fixed rod 6, the fixed block 5 is in friction contact with the hook tip part of the hook body 1, at the moment, the device finishes the early-stage preparation work, when the article that this device hook was got off needs, only need press slider 13 and make it no longer inject dead lever 6, place the position that needs again with the article in the coupler body 1, at this moment, dead lever 6 can be because of torsion spring 18's effect rebound to make fixed block 5 break away from the hook point part of coupler body 1, directly at last with the coupler body 1 in the article directly take out can, this moment this device work is ended.

The utility model discloses a dead lever 6 turns up in the setting to make 1 inner space of coupler body can not change, the condition of dead in the lifting hook of effectual reduction object card, rethread dead lever 6 push down fixedly with slider 13 to the injecing of dead lever 6, thereby realize dead lever 6 and carry out blockade effect to coupler body 1, the effectual condition of having reduceed the lifting hook unhook.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
