Abstract
The utility model discloses a control rod guide cylinder installation tool for a nuclear power plant, which comprises a tightening member, wherein the tightening member is an adapter with a long rod, the total length of the tightening member is more than the length of a guide cylinder at the upper part, and at least one end of the long rod is provided with a bolt head matched with the end part of a bolt to be screwed on a guide cylinder flange. Compared with the prior art, the control rod guide cylinder installation tool has the advantage that a force applying operation plane of the bolt to be screwed is translated to the top of the guide cylinder at the upper part through the tightening member, so that the tightening action is not influenced by an operation space, and a tightening torque is conveniently measured.
Description
Technical field
The utility model relates to the control rod guide cylinder erecting tools of nuclear power station.
Background technology
The control rod guide assembly is the important component part of nuclear power station reactor inner member, when equipment dispatches from the factory it with heap in other members separate packing, the independent transportation, and then assemble at the construction field (site), adjustment and fastening.
See also Fig. 1 to shown in Figure 3, control rod guide assembly 10 has 61 groups, and after the height of all guide cylinders 12 and position adjustment is suitable, every group was fastened on the top in-pile component 20 by four bolts 14 on the middle flange respectively, and Tightening moment is 480 ~ 500Nm.Because placed in close between each group control rod guide assembly, the common wrench handle is longer, and the 14 o'clock handles that tight a bolt can interfere with place guide cylinder 12 and contiguous guide cylinder 12, tighten application of force operating difficulties.Therefore, the installation of guide cylinder 12 at present can only utilize short handle L type spanner to carry out, owing to receive the operating space restriction can't 360 ° of rotations, can only tighten by multistep.
Obviously, above-mentioned tightening method has following shortcoming: 1, the short handle L type spanner arm of force is shorter, and the Tightening moment that guide cylinder 12 requires is bigger, so rundown process is required great effort very much; Whether 2, screw-down torque can't be measured, can't learn and tighten; 3, operation inconvenience.
In view of this, necessaryly provide a kind of and can realize control rod guide cylinder Fast Installation and fastening erecting tools.
Summary of the invention
The purpose of the utility model is: a kind of control rod guide cylinder erecting tools of nuclear power station is provided, to solve the problem of guide cylinder difficult installation.
To achieve these goals; The utility model provides a kind of control rod guide cylinder erecting tools of nuclear power station; It comprises tightens part; Saidly tighten the adapter that part is a belt length bar, its overall length is greater than the length of top guide cylinder, at least one end of stock for the guide cylinder flange on wait the suitable bolt head in end that tights a bolt.
A kind of improvement as the control rod guide cylinder erecting tools of the utility model nuclear power station also comprises auxiliary member, and auxiliary member is the anchor ear that is welded with at least one collar, and the size of the collar is suitable with the stock diameter of tightening part.
As a kind of improvement of the control rod guide cylinder erecting tools of the utility model nuclear power station, the quantity that tights a bolt of treating on the quantity of the said collar and the guide cylinder flange is identical, and the position corresponds to each other.
As a kind of improvement of the control rod guide cylinder erecting tools of the utility model nuclear power station, said two ends of tightening the part stock all be with the guide cylinder flange on wait to tight a bolt the suitable outer-hexagonal bolt head of hexagon socket head of end.
As a kind of improvement of the control rod guide cylinder erecting tools of the utility model nuclear power station, said length of tightening part is 1m ~ 3m.
As a kind of improvement of the control rod guide cylinder erecting tools of the utility model nuclear power station, said length of tightening part is 1.6m.
Compared with prior art, the utility model moves to the top of top guide cylinder through tightening application of force operation planar that part will be to be tighted a bolt, makes and tightens the influence that action does not receive the operating space, and be convenient to measure screw-down torque.

The specific embodiment
See also Fig. 1 to shown in Figure 7, the control rod guide cylinder erecting tools of the utility model nuclear power station comprises tightens part 40 and auxiliary member 60.
During use; Insert in the collar of auxiliary member 60 tightening part 40; The outer-hexagonal bolt head 44 that to tighten part 40 1 ends again inserts tight a bolt 14 end of on the flange of guide cylinders 12 one of them; Afterwards auxiliary member 60 is fixed on the upper end of guide cylinder 12, four collars 62 are 14 corresponding with tighting a bolt of four orientation respectively.Like this; Tighten just will tight a bolt 14 application of force operation planar of part 40 and moved to the top of top guide cylinder 12, make and tighten the influence that action does not receive the operating space, and 14 the interior hexagonal of will tighting a bolt converts the outer-hexagonal of outer-hexagonal bolt head 44 to; As long as the operator is with external hex bolts head 44 application of forces of torque spanner; Can will tight a bolt 14 tighten, and can measure screw-down torque easily, satisfy installation requirement.
60 pairs of auxiliary members are tightened stock 42 upper ends of part 40 and are played fixation; Can effectively prevent to tighten part 40 in the process of external hex bolts head 44 application of forces of torque spanner, produce eccentric with rock, thereby guarantee to be applied to the tighting a bolt on 14 of flange that moment on the spanner can be delivered to guide cylinder 12.When one tight a bolt 14 be tightened after, the anchor ear 64 of auxiliary member 60 can rotate, but the stock 42 that will tighten part 40 extracts out and be inserted in the collar 62 in next orientation, can continue the next one tighted a bolt and 14 tighten operation.
Can know through above description; The control rod guide cylinder erecting tools of the utility model nuclear power station is simple in structure, and the fast and reliable that can solve the control rod guide cylinder is installed with fastening, is convenient to the application of force in the installation; Can be used in combination torque spanner; Satisfy to install, fastening in required torgue measurement requirement, therefore use reliable, be easy to promote.
According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to is in the protection domain of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
