The lever type bearing pad hoisting device comprises a hoisted bearing pad, a communicating pipe and an adjustable lever, wherein the hoisted bearing pad is fixed at one end below the adjustable lever by a chain block, and a balancing weight is arranged at the other end below the adjustable lever and is fixed below the adjustable lever by a steel wire rope; a first adjusting mechanism and a second adjusting mechanism are arranged above the end with the balancing weight of the adjustable lever; the first adjusting mechanism refers to a main hook of a turbine hall overhead crane; the second adjusting mechanism refers to an auxiliary hook of the turbine hall overhead crane; the chain block, the balancing weight, the first adjusting mechanism and the second adjusting mechanism are all connected with the adjustable lever through clamping rings; the adjustable lever is made of profile steel and the balancing weight is made of a steel material or a cement material. The lever type bearing pad hoisting device is applicable to working in a space with an obstacle at the upper part, has the characteristics of taking materials rapidly and conveniently, being simple to manufacture, convenient to work and low in cost, and the like, and has good practical performance and high socioeconomic benefits.
Description
Technical field:
The utility model relates to a kind of lifting device; relate to particularly a kind of lever bearing shell hanging apparatus; there is the lifting of the equipment of obstacle that a kind of new lifting mode is provided for top, operating area, be convenient in obstacle, guarantee the normal operation of lifting above protection.
Background technology:
Along with the progress of material technology, the generating capacity in power plant maximizes and high parameter increasingly, the meanwhile increasingly stringent to quality, technological requirement, and the dissembling inspection of bearing shell is the important procedure between installation, turn(a)round as power plant.Traditional mode of operation (referring to Fig. 1) can not meet requirements, easily communicating pipe and outer casing between Steam Turbine Through IP Admission and low pressure cylinder, low pressure cylinder and low pressure cylinder are caused to damage, thereby cause the waste of human and material resources and financial resources, increase the cost of overhaul of enterprise.The work that how to solve normal lifting operation and device security becomes the task of top priority.
Utility model content:
Technical problem to be solved in the utility model is: a kind of lever bearing shell hanging apparatus is provided, overcomes the contradictory problems between inspecting bearing shell and equipment protection, under the prerequisite that ensures Plant in good condition, promote carrying out smoothly of inspecting bearing shell work.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of lever bearing shell hanging apparatus, comprise by lifting bearing shell, communicating pipe and adjustable lever, described one end that is fixed on adjustable lever below by lifting bearing shell by chain block, the other end of described adjustable lever below is provided with clump weight, and described clump weight is fixed on the below of adjustable lever by steel rope; Be provided with clump weight one end adjustable lever above be provided with the first regulating mechanism and the second regulating mechanism.
Described the first regulating mechanism is the main hook of steam turbine building driving, and described the second regulating mechanism is the auxiliary hook of steam turbine building driving; Described chain block, clump weight, the first regulating mechanism and the second regulating mechanism are all connected with adjustable lever by snap ring.
Described adjustable lever is processed by shaped steel; Described clump weight is processed by Steel material or cement material.
In the time using the utility model:
1. operation is prepared: by adjustable lever make, after clump weight chooses, corresponding each regulating mechanism suspension centre is bundled on the major and minor hook of steam turbine building driving by steel rope, clump weight is suspended on to the suspension centre below of the second regulating mechanism, then chain block is hung on the suspension centre of adjustable lever (selection of chain block should be determined according to bearing shell actual weight);
2. bearing shell is installed: bearing shell to be installed is suspended on to chain block below, start adjustable lever and it is carried out to levelling, starting driving delivers to bearing shell behind the installation site of bearing shell, fall adjustable lever after rise to certain altitude, then finely tune by chain block, until bearing shell is placed on installation site to the end of job;
3. bearing shell dismounting: the chain block of progressively adjusting (movements of upper and lower, left and right and front and back by adjustment (adjusting) lever) adjustment (adjusting) lever below to bearing shell top with communicating pipe below space have certain safety distance after, implement bearing shell to carry out preliminary lifting, leave rotor to after outside safety distance until bearing shell, start driving and bearing shell is winched to maintenance department, the end of job.
Positive beneficial effect of the present utility model is:
1, the utility model has been designed the new technical scheme of bearing shell installation, dismounting and has been tested on the basis of traditional work, facts have proved that this instrument can complete fast and effectively installation, dismounting and the inspection work of turbine bearing pad in guarantee equipment (communicating pipe and outer casing) safety, destruction to bearing shell top communicating pipe and outer casing before having solved, has improved work efficiency.
2, simple to operate, the practical convenient of the utility model, highly versatile, instrument its preparing materials highly versatile, reusable, saves tooling cost, reduces spillage of material, and can improve processing technology quality, shortens the engineering time, reduces construction costs.
Brief description of the drawings:
Fig. 1 is the structural representation of tradition lifting bearing shell operation;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further explained and explanation:
Fig. 1 is the structural representation of tradition lifting bearing shell operation, and 1 is by lifting bearing shell, and 8 is lifting rope, and 7 is by the communicating pipe of lifting rope reciprocating collision.
Fig. 2 is structural representation of the present utility model, a kind of lever bearing shell hanging apparatus, comprise by lifting bearing shell 1, communicating pipe 7 and adjustable lever 3, be fixed at one end of adjustable lever 3 belows by chain block 2 by lifting bearing shell 1, the other end below adjustable lever 3 is provided with clump weight 4, and clump weight 4 is fixed on the below of adjustable lever 3 by steel rope; Be provided with clump weight 4 one end adjustable lever 3 above be provided with the main hook that the first regulating mechanism 5 and the second regulating mechanism 6, the first regulating mechanisms 5 are steam turbine building driving, the auxiliary hook that the second regulating mechanism 6 is driven a vehicle for steam turbine building.Wherein: chain block 2, clump weight 4, the first regulating mechanism 5 are all connected with adjustable lever 3 by snap ring with the second regulating mechanism 6; Adjustable lever 3 is processed by shaped steel, and clump weight 4 is processed by Steel material or cement material.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
