Abstract
The invention discloses a novel device for preventing a crane sling from dropping off. The novel device is produced by assembling and welding four rectangular steel plates, a square steel plate, four rectangular steel strips and two U-shaped steel bars. Such set of novel crane sling avoids the conventional single hanging structure, adds an inverted U-shaped steel bar, which inclines oppositely relative to the steel bars on the sling, on the basis of the original sling, and the U-shaped steel bars with downward openings and the inverted U-shaped steel bar with an upward opening on the sling are welded into an elliptic shape which is matched with a crane hook; by adopting the structure, a flexible rotation, bilateral interlocking, and opposition to the opening of the crane hook are achieved, the safety level is increased, the service life of the sling is prolonged, an accident that the sling drops off to injure on-site working staff is avoided, and higher safety and economic benefits are brought to enterprises and the society.
Description
Technical field
The invention belongs to aluminum smelting technology technical field is and in particular to a kind of new device preventing crown block sling from coming off
Background technology
China's aluminum electrolysis require relatively sternly to safety management, and the groundwork of potroom is pole changing, and overhead traveling crane is potroom pole changing
Capital equipment, crown block sling be also change poles work indispensable instrument, every overhead traveling crane of potroom hang daily anode be no less than 100 groups, and
The suspender that overhead traveling crane hook is used when falling sometimes according to inaccurate anode rod it may appear that suspender comes off and injures the phenomenon of field personnel by a crashing object and often send out
Raw.How to prevent overhead traveling crane to be hooked in greatly lifting anode or will not fall off in the process of walking, be the problem of domestic aluminum industry research although a lot of learn
Person works out many methods to prevent such crown block sling from coming off, but could not settle the matter once and for all the time, and a lot of aluminium manufacturers hang to prevent overhead traveling crane
Tool comes off when walking or hang anode, the very strong driving force down impacted in the face of overhead traveling crane hook in overhead traveling crane hook shielding card installed above, overhead traveling crane shielding card
With crown block sling according to being forbidden to withstand on the top power on anode rod, can will be bad for overhead traveling crane shielding card top, do not have protective action, because shielding card material is relatively thin,
Sometimes damage several shielding cards within one day, cause workload to increase to craneman or check man, the working time is delayed, the bad phenomenon such as Master Cost increase,
Also bring larger challenge to safety in production.
Content of the invention
It is an object of the invention to overcoming prior art defect, there is provided a kind of new device preventing crown block sling from coming off.
Based on above-mentioned purpose, this invention takes following technical scheme:
A kind of new device preventing crown block sling from coming off, including 4 blocks of rectangular steel plates, is all drilled with one than on anode rod in the middle of every block of steel plate
Steel pipe aperture 5mm bigger than normal circular aperture, 1 block of square steel plate, its size 15-20mm bigger than anode rod size, 4 block length square bar laths,
1 long u shape reinforcing bar and 1 short u shape reinforcing bar, form (Fig. 1) by assembly welding, this new device is overhead traveling crane anticreep suspender again.
During overhead traveling crane anticreep suspender operation experiments of the present invention, site operation personnel needs by parallel for overhead traveling crane anticreep suspender picking-up, short u-shaped reinforcing bar down,
Hang 135 ° -150 ° of direction suspender could be arranged on overhead traveling crane hook, no matter hang anode or walking swings all without splitting away off, unless hung
Mutually temperature conjunction is possible to come off the pendulum angle of tool with the angle of mounting hanger, the top power bump test by the whipping of ultralimit and on anode rod
Prove during whole overhead traveling crane hanging, do not have any action can be 100% anti-anti-avulsion by the angle of suspender angle swinging to 100 from the point of view of this design
The instrument falling, prevents the hanging structure that the principle coming off is derived from suspender from there occurs change.
It is an advantage of the current invention that: the single hanging structure before avoiding of this set Novel crown block anticreep suspender, increased on the basis of original suspender
One projecting u-shaped reinforcing bar, and this projecting u-shaped reinforcing bar becomes countertendency with the reinforcing bar on suspender before, the mouth down u shape reinforcing bar on suspender and mouth court
Upper u shape hangs upside down reinforcement welding ovalisation shape with overhead traveling crane hook mutually gently, and it is contrary with crown block hook mouth that this structure achieves flexible, the bilateral mutual button of rotation
Effect, improve safe grade, extend the service life of suspender, it is to avoid suspender comes off and injures field personnel's security incident by a crashing object, to enterprise
Industry and society bring larger safety and economic benefit.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side view of the present invention；
Fig. 3 is the operation diagram of the present invention；
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further details, but protection scope of the present invention not limited to this.
As shown in figure 1, a kind of new device preventing crown block sling from coming off of the present invention, including the 4 block length square plates 1 that 5-10mm is thick, every piece
The centre position of steel plate is drilled with an aperture 4, and aperture diameter is easy to pin insertion (Fig. 3 during operation than the big 5mm on anode rod；8), 4
Again one block of square steel plate is welded to top 6 after block steel plate welding fabrication, acts on shelves and live shifting on anode rod, and the hole on anode rod can be made
Footpath is identical with the aperture location that suspender seals in, and φ 18-32 steel bar meter is become, the top 2 of long u-shaped reinforcement welding to crown block sling, then by φ 18-32
Steel bar meter becomes, the top 3 of short u-shaped reinforcement welding to long u-shaped reinforcing bar, will become opposite direction, angle with long u-shaped reinforcing bar during short u-shaped reinforcement welding
For 45-60 °, the lower edge of 4 thick block length bar steel plate weld to suspenders of 5-10mm is become bell shape 5, is easy to anode rod and slips in suspender.
As shown in Figure 3 during use: site operation personnel holds up projecting 135 ° -150 ° of direction by parallel for overhead traveling crane anticreep suspender, and short u-shaped reinforcing bar is hung down
7 on overhead traveling crane hook, overhead traveling crane reaches the top of the anode rod needing hanging, and suspender is dropped into 9 on anode rod, inserts suspender pin 8, hangs
Play anode unit 9,10,11,12,13 and carry out electrolysis bath pole changing.
Finally illustrate: above-mentioned enforcement is merely to illustrate and unrestricted technical scheme, any equivalent that the present invention is carried out and not
Depart from the modification of spirit and scope of the invention or local is replaced, it all should be covered within the scope of the claims in the present invention protection.
