Description

A kind of L-type lifting auxiliary tool

Technical field

The utility model belongs to lifting device technical field, is related to a kind of L-type lifting auxiliary tool.

Background technology

Currently, since the limitation of design or operation field leads to loop wheel machine during many equipment hoisting actual jobs Or the suspension hook of driving is not at vertical centre, often will appear the askew dangerous operation behaviour for skewing and hanging, while being also required to more people Cooperation, aligns, could complete the lifting operation of equipment or material by force.

By taking the maintenance of iron making and sintering process single roll crusher as an example：It is necessary before going into operation every time due to the needs of design of sinter machine Hang the hoisting port cover board below booting tail dust excluding hood（Totally six pieces, every piece of 1m*2.9m, weight 400KG or so）, it is broken that single roller can be carried out The upkeep operation of broken machine projects；The hoisting port cover board below sinter machine discharge end dedusting cover must be hung back after completion again every time.

Referring to can see cover board lifting operation in Fig. 1, there are following problems.

1, since 8 protrusion of sinter machine discharge end dedusting dust cover by operation field is limited, travelling crane hook 6 not cover board 9 it is vertical in Heart position（Deviate central point 800mm）, only leaning on operating personnel to push and pull cover board 9 can just hang out or return dress, and labor intensity is higher.

2, the askew of the lifting of cover board 9 skews crane operation, and the protrusion of sinter machine discharge end dedusting cover 8 rubs with 6 steel wire rope 5 of travelling crane hook, It is bound to cause 5 breakdown of steel wire rope, easily occurrence of equipment or personal safety accident.

3, sintering machine platform 7 and about 10 vertical range of single roll crusher platform are 9 meters, the operating personnel that cover board 9 lifts Face side state in eminence, there are job safety high risks.

Utility model content

In order to overcome the disadvantages mentioned above of the prior art, the utility model to provide a kind of L-type lifting auxiliary tool, there is design Rationally, the features such as simple in structure, safe and reliable, easy to use, can lead to avoid the limitation due to design or operation field It causes during lifting actual job, the askew dangerous operation for skewing and hanging occur in loop wheel machine or travelling crane hook when being not at vertical centre Behavior, it is ensured that equipment or personal safety.

Technical solution adopted by the utility model to solve its technical problems is：A kind of L-type lifting auxiliary tool, including one A L-shaped holder, wherein one end add counterweight, offer the holes A at the right angle end of holder, the holes B offered in the other end.

The holes A are used to coordinate with travelling crane hook, are lifted by crane holder by driving steel wire rope.

The holes B hang single roller cover board by steel wire rope, and cover board is hung on the corresponding position of sintering machine platform.

The holder side is provided with the sinter machine discharge end dedusting dust cover of protrusion.

The utility model has the beneficial effects that：It can cause lifting to avoid the limitation due to design or operation field During actual job, there is the askew dangerous operation behaviour for skewing and hanging in loop wheel machine or travelling crane hook when being not at vertical centre, really Equipment or personal safety are protected；Change due to loop wheel machine or travelling crane hook be not at vertical centre occur it is askew skew hang when, need The phenomenon that more people draw but also pull, align by force not only, improves operating efficiency；As long as 3 people cooperation can easily align equipment, complete Lift work；Labor intensity is reduced, operating personnel is reduced；With reasonable design, simple in structure, safe and reliable, user Just the features such as.

Description of the drawings

Fig. 1 is existing lifting operation schematic diagram；

Fig. 2 is the utility model structure diagram；

Fig. 3 is that the utility model implements schematic diagram.

In figure：1- holders, 2- counterweights, the holes 3-A, the holes 4-B, 5- steel wire ropes, 6- travelling crane hooks, 7- sintering machine platforms, 8- machines Tail dedusting dust cover, 9- cover boards, 10- single roll crusher platforms.

Specific implementation mode

The utility model is further illustrated with reference to the accompanying drawings and examples.

Referring to Fig. 2 and Fig. 3, a kind of L-type lifts auxiliary tool, including a L-shaped holder 1, and one end installs additional wherein There is counterweight 2, offers the holes A 3 at the right angle end of holder 1, the holes B 4 are offered in the other end.

The holes A 3 are used to coordinate with travelling crane hook 6, are lifted by crane holder 1 by driving steel wire rope 5.

The holes B 4 hang single roller cover board 9 by steel wire rope 5, and cover board 9 is hung on 7 corresponding position of sintering machine platform.

1 side of the holder is provided with the sinter machine discharge end dedusting dust cover 8 of protrusion.

The utility model can cause to avoid the limitation due to design or operation field in lifting actual job process In, there is the askew dangerous operation behaviour for skewing and hanging in loop wheel machine or travelling crane hook 6 when being not at vertical centre, it is ensured that equipment or people Body safety；Change due to loop wheel machine or travelling crane hook 6 be not at vertical centre occur it is askew skew hang when, need more people draw not only but also The phenomenon that pulling, aligning by force improves operating efficiency；As long as 3 people cooperation can easily align equipment, lifting work is completed； Labor intensity is reduced, operating personnel is reduced；Has the characteristics that reasonable design, simple in structure, safe and reliable, easy to use.
