Abstract

The utility model discloses a prevent novel device that overhead traveling crane hoist drops, including 4 blocks of rectangular steel sheets, 1 positive square steel plate, 4 block length square steel plate strip, 2 U -shaped steel bars form through assembly welding. Single suspended structure before the novel overhead traveling crane hoist of this cover has been avoided, a reversal of the natural order of things U shaped steel muscle has been increased on original hoist basis, and this reversal of the natural order of things U shaped steel muscle becomes to turn over with reinforcing bar on the hoist before and is inclined to, mouth down U -shaped steel bars on the hoist is gentle mutually with the overhead traveling crane hook with mouth U -shaped reversal of the natural order of things up welded steel ovalisation form, this structure has realized rotating in a flexible way, the hook mouth opposite effect is hung with the overhead traveling crane to bilateral each other knot, safe grade has been improved, the life of hoist has been prolonged, it injures site work personal security accident by a crashing object to have avoided the hoist to drop, bring great safety and economic benefits for enterprise and society.

Description

A kind of new device preventing crown block sling from coming off

Technical field

This utility model belongs to aluminum smelting technology technical field, is specifically related to a kind of new device preventing crown block sling from coming off

Background technology

Safety management is required tighter by China's aluminum electrolysis, the groundwork of potroom is pole changing, overhead traveling crane is the capital equipment of potroom pole changing, crown block sling is also the change poles indispensable instrument of work, every day hung anode no less than 100 groups by potroom every overhead traveling crane, and the suspender that overhead traveling crane hook uses when falling sometimes according to inaccurate anode rod, it may appear that the suspender phenomenon injuring field personnel by a crashing object that comes off often occurs. overhead traveling crane how is prevented to be hooked in greatly lifting anode or do not come off in the process of walking, it it is the problem of domestic aluminum industry research, although a lot of scholar's research go out many ways to prevent this type of crown block sling from coming off, but could not settle the matter once and for all the time, a lot of aluminium manufacturers come off when walking or hanging anode to prevent crown block sling, at overhead traveling crane hook shielding card installed above, very strong driving force and crown block sling that overhead traveling crane hook faced by overhead traveling crane shielding card down impacts shine the top power being forbidden to withstand on anode rod, can by bad for overhead traveling crane shielding card top, do not have protective action, owing to shielding card material is relatively thin, sometimes within one day, several shielding card is damaged, workload is caused to increase to craneman or check man, working time is incured loss through delay, the bad phenomenon such as Master Cost increase, also bigger challenge is brought to safety in production.

Utility model content

The purpose of this utility model is in that to overcome prior art defect, it is provided that a kind of new device preventing crown block sling from coming off.

Based on above-mentioned purpose, this utility model takes following technical scheme:

A kind of new device preventing crown block sling from coming off, including 4 blocks of rectangular steel plates, the circular aperture of a 5mm bigger than normal than the steel pipe aperture on anode rod all it is drilled with in the middle of every block plate, 1 block of square steel plate, its size 15-20mm bigger than anode rod size, 4 block length square bar laths, 1 root length U-shaped reinforcing bar and 1 short U-shaped reinforcing bar, forming (Fig. 1) by assembly welding, this new device is again overhead traveling crane anticreep suspender.

During this utility model overhead traveling crane anticreep suspender operation experiments, site operation personnel needs the overhead traveling crane parallel picking-up of anticreep suspender, short U-shaped reinforcing bar is down, suspender could be arranged on overhead traveling crane hook by 135 ��-150 �� of direction of reversal of the natural order of things, no matter hang anode or walking swings all without splitting away off, it is possible to come off unless the pendulum angle of suspender closes with the angle temperature mutually of mounting hanger, proved by the whipping of ultralimit and the top power bump test on anode rod, whole overhead traveling crane hanging process does not have any action can by the angle of suspender angle swinging to 100, it is 100% instrument preventing from coming off from this design, prevent the principle come off from there occurs change from the hanging structure of suspender.

The utility model has the advantage of: the hanging structure (Fig. 4) that this set Novel crown block anticreep suspender is single before avoiding, original suspender basis adds one and hangs upside down U-shaped reinforcing bar, and this hangs upside down U-shaped reinforcing bar and becomes countertendency with the reinforcing bar on suspender before, it is mutually gentle with overhead traveling crane hook that mouth down U-shaped reinforcing bar on suspender and mouth U-shaped upward hang upside down reinforcement welding ovalisation shape, this structure achieves rotation flexibly, bilateral mutual button and crown block hook mouth opposite effect, improve safe grade, extend the service life of suspender, avoid suspender to come off and injure field personnel's security incident by a crashing object, bigger safety and economic benefit is brought to enterprise and society.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further details, but protection domain of the present utility model is not limited to this.

As shown in Figure 1, a kind of new device preventing crown block sling from coming off of this utility model, including the 4 block length square plates 1 that 5-10mm is thick, the centre position of every block plate is drilled with an aperture 4, and when aperture diameter is easy to operate than the big 5mm on anode rod, pin inserts (Fig. 3, 8), again by one piece of square Plate Welding to top 6 after 4 block plate welding fabrications, act on shelves and live shifting on anode rod, and the aperture location that the aperture on anode rod seals in suspender can be made identical, �� 18-32 steel bar meter is become, long U-shaped reinforcement welding is to the top 2 of crown block sling, again �� 18-32 steel bar meter is become, short U-shaped reinforcement welding is to the top 3 of long U-shaped reinforcing bar, opposite direction is become with long U-shaped reinforcing bar during short U-shaped reinforcement welding, angle is 45-60 ��, the lower edge of 4 thick for 5-10mm block length bar Plate Weldings to suspender is become horn mouth shape 5, it is easy to anode rod slip in suspender.

During use as shown in Figure 3: site operation personnel holds up 135 ��-150 �� of direction of reversal of the natural order of things by parallel for overhead traveling crane anticreep suspender, short U-shaped reinforcing bar hangs on overhead traveling crane hook 7 down, overhead traveling crane reaches the top of the anode rod needing hanging, suspender is dropped on anode rod 9, inserting suspender pin 8, anode unit 9,10,11,12,13 of slinging carries out electrolysis bath pole changing.

Finally illustrate: above-mentioned enforcement is merely to illustrate and unrestricted the technical solution of the utility model; any equivalent replacement that this utility model is carried out and amendment or local without departing from this utility model spirit and scope are replaced, and it all should be encompassed within the scope of this utility model claim protection.
