In, differential expansion improves between pipe and pipe, the factors such as flue gas disturbance when along with operation, the relative displacement of pipe way in tube panel
Situation becomes increasingly complex, and the stress that sliding positioning device will receive is also increasing, therefore the requirement to tube panel positioning device
It improves.
Summary of the invention:
In order to overcome the above problem of the existing technology, the object of the present invention is to provide a kind of slidings for tube panel to position dress
It sets and tube panel pipe localization method.
Above-mentioned purpose is realized by following technical scheme:
A kind of sliding positioning device for tube panel, composition includes: L-type movable clip block and H-type movable clip block, the L-type
Two L-type chimbs of movable clip block are embedded in respectively in the H-type groove of the H-type movable clip block, to be formed a kind of mutual
The structure of limit plays the positioning action between pipe, and there are gaps between chimb and groove, to guarantee between movable clip block
Energy sliding is smooth, does not influence the thermal expansion curve of pipe way, and the part that the H-type movable clip block is contacted with pipe has arc
Degree, to guarantee to be tightly combined, the L-type movable clip block bottom has bottom edge, and two L-type chimbs are connected to by the bottom edge
It is formed together the structure of an entirety.
The tube panel pipe localization method of the above-mentioned sliding positioning device for tube panel, by described between tube panel adjacent pipe
H-type movable clip block connected with L-type movable clip block, H-type movable clip block and L-type movable clip block are welded in two adjacent pipes respectively
On, the H-type groove of H-type movable clip block mutually agrees with two L-type chimbs of L-type movable clip block, forms a kind of mutual limit
Structure type, between groove and chimb again remain certain gap, it is smooth to guarantee to slide between movable clip block, not
Between influence tube panel under the premise of pipe thermal expansion curve, made by the mutual limit between movable clip block to play the positioning of tube panel
With.
Beneficial effects of the present invention:
Advantages of the present invention major embodiment in the following areas, does not influence the thermal expansion curve of heating surface tube panel pipe way, to tube panel
The ability of positioning is stronger, the stress that can be born operation, produce, generate in transport, and movable clip block is practical reliable.H-type movable clip block
H-type groove can mutually agree with two L-type chimbs of L-type movable clip block, form a kind of structure of mutual limit
Form remains certain gap again between groove and chimb, smooth to guarantee to slide between movable clip block.Movable clip block with
Pipe contact portion has certain radian to guarantee to be tightly combined between the two.
Present invention employs a kind of sliding positioning devices applied on boiler heating surface tube panel, and a H-type activity is pressed from both sides
Block and a pair of of L-type movable clip block are welded in respectively on two pipes adjacent in tube panel, the pipe thermal expansion curve between not influencing tube panel
Under the premise of, the positioning action of tube panel is played by the mutual limit between movable clip block.

Specific embodiment:
Embodiment 1:
A kind of sliding positioning device for tube panel, composition includes: L-type movable clip block 1 and H-type movable clip block 2, the L
Two L-type chimbs 3 of type movable clip block are embedded in respectively in the H-type groove 4 of the H-type movable clip block, to form one kind
The structure mutually limited plays the positioning action between pipe 5, and there are gaps between chimb and groove, to guarantee movable clip block
Between can slide smooth, do not influence the thermal expansion curve of pipe way, the part that the H-type movable clip block is contacted with pipe has
Radian, to guarantee to be tightly combined, the L-type movable clip block bottom has bottom edge 6, and the bottom edge connects two L-type chimbs
It is connected together to form the structure of an entirety.L-type movable clip block is the elongate configuration that section is " L " type, as shown in fig. 1, H-type
Movable clip block is the elongate configuration that section is " H " type, and L-type movable clip block and the cooperation of H-type movable clip block make L-type activity when assembling
Fixture block is grown with the one end on bottom edge, and one end of H-type movable clip block is grown, that is to say, that the two is not to be completely coincident.
