Description
Technical field
The utility model belongs to boiler maintenance technical field, and especially a kind of reheater blocks up the dedicated lifting tool of valve.
Background technique
During each shutdown maintenance of boiler, maintenance personal needs to import and export reheater stifled valve and carries out installing closure plate and recovery additional
Flow guide sleeve.When stifled valve dismounts work, restraining plate and hanging out is a very difficult job.Due to caused by equipment service condition,
Restraining plate cannot be hung out easily with chain block.Stifled valve genuine design suspension centre is too small, and lifting strength causes and suspension centre institute when excessive
The nose that hangs of cooperation is deformed.If steel wire buckle bolt is hung over and is restrained as suspension centre on plate lead screw, due to steel wire buckle by service personnel
All it is that manual operation necessarily leads to inevitable error with chain block cooperation, causes to restrain plate discontinuity.Steel wire buckle
The pressure ring restrained on the outside of plate is squeezed with the chain block cooperation excessive side uphill process of stress, causes pressure ring to generate deformation, destroys
Device structure.In addition, traditional lifting method also occurs that chain rupture, suspension centre tripping, staff's personal injury is caused.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of design rationally, it is safe and reliable and make
The dedicated lifting tool of valve is blocked up with convenient reheater.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of stifled dedicated lifting tool of valve of reheater, including two stress channel steels, clamp force bolt, clamp force nut, described two
Stress channel steel leans against setting and the top and bottom among two stress channel steels are solidly installed by steel plate respectively, upper
Relative position is formed with two pairs of channel steel bolts hole on face steel plate and following steel plate, clamp force bolt is equipped on channel steel bolt hole, tightly
The upper end of power bolt is equipped with clamp force nut, and the lower end of clamp force bolt enters in the containing crab bolt hole restrained on plate, utilizes
The clamp force of clamp force bolt and clamp force nut, which drives, restrains plate rising.
Top and bottom among two stress channel steels are solidly installed by welding manner and steel plate.
The advantages and positive effects of the utility model are as follows:
1, the utility model is mounted on reheater and blocks up on valve, is led by the clamp force that clamp force bolt cooperates with clamp force nut
The promotion of making sheet is detached from until restraining plate, and it is equally loaded and not will cause equipment damage, while it is hidden to greatly reduce safety
Suffer from.
2, the utility model structure is simple, light, is conducive to carry and use, significantly reduces working strength.
3, in use, clamp force bolt stroke is short for the utility model, is promoted quickly, can effectively save maintenance
Time.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the side view of Fig. 1；
Wherein, 1- clamp force bolt, 2- clamp force nut, 3- stress channel steel, 4- restrain plate, 5- steel plate, and 6- restrains crab bolt hole,
7- channel steel bolt hole.
Specific embodiment
The utility model embodiment is further described below in conjunction with attached drawing:
A kind of stifled dedicated lifting tool of valve of reheater, as shown in Figure 1 to Figure 3, including two stress channel steels 3, clamp force bolt
1, clamp force nut 2, two stress channel steels lean against setting and the top and bottom among two stress channel steels are respectively welded
Have steel plate 5, so that two stress channel steel top and bottom are tightly combined together with steel plate, can be effectively prevented in this way by
Deformation occurs for power channel steel.Two channel steel bolts hole 7 are formed respectively on steel plate and following steel plate above, in channel steel bolt hole
On clamp force bolt is installed, clamp force nut and gasket are installed on the clamp force bolt of upper end, constantly fasten two using spanner
Clamp force nut utilizes clamp force spiral shell so that clamp force bolt is moved down up to entering in the containing crab bolt hole 6 restrained on plate 4
The clamp force of bolt clamp force nut, which drives, restrains plate rising, finally to restrain plate disengaging.
The design principle of the utility model are as follows: just meet since stifled valve restrains the distance between plate top surface and stifled valve top surface
The height of promotion, therefore, the utility model are created a diversion the promotion of plate using the clamp force that clamp force bolt and clamp force nut cooperate, directly
It is detached to plate is restrained.I-steel deforms in order to prevent, solves the problems, such as the stress of spandrel girder, two bar groove steel backs by it is intermediate there are
The gap 30mm, the top and bottom steel plate (thickness 20mm) among two channel steels are welded on above channel steel as the drawing of channel steel vertical plane
Closely, capable of effectivelying prevent channel steel in this way, deformation occurs.The channel steel bolt hole of diameter 20mm is finally got on the steel plate of top and bottom, benefit
It is created a diversion the promotion of plate with the clamp force of clamp force bolt and the cooperation of clamp force nut.Prove that this tool can be fine by practical operation
Ground meets actual use.
It is emphasized that embodiment described in the utility model be it is illustrative, without being restrictive, therefore this reality
Embodiment described in specific embodiment is not limited to novel, it is all according to the present utility model by those skilled in the art
The other embodiments that technical solution obtains also belong to the range of the utility model protection.
