Description
Technical field
The present invention relates to a kind of supporting plate structure, particularly a kind of gripper shoe fixed structure and there is its case tube heat exchanger.
Background technology
Gripper shoe assembly is the important component part of centrifuge, screw machine central air-conditioning shell and tube exchanger (also known as full-liquid type heat exchanger), gripper shoe plays and supports heat exchanger tube, reduces heat exchanger tube vibrations in unit running process, promotes the effect in heat exchanger tube service life.The fixed form of usual gripper shoe assembly is that gripper shoe is connected with case weld in enclosure interior.But the structure that this gripper shoe is welded to connect, housing is semi-closed casings, is difficult to use automation group to equipment, and the middle part generally climbing into enclosure interior by welder carries out welding, postwelding scarfing cinder, not only operating difficulties, and working environment is very severe.According to long-arm welding pistol, exist again and cannot remove the defects such as welding slag, there is the system of easily blocking central air-conditioning in welding slag, affects unit operation.
To sum up, a kind of gripper shoe fixed structure without the need to carrying out being welded and fixed in the middle part of enclosure interior is provided to be the technical problem that those skilled in the art are badly in need of solving.
Summary of the invention
Based on background technology Problems existing, the invention provides a kind of gripper shoe fixed structure, to realize facilitating the installation between gripper shoe and housing to fix.
For realizing the gripper shoe fixed structure that the object of the invention provides, comprise gripper shoe, housing, gripper shoe is arranged in housing, and gripper shoe is fixedly installed slide bar, and case inside wall is fixedly installed fixed strip; Slide bar and fixed strip resilient engagement, fix to make gripper shoe and housing.
Slide bar is arranged on the below of gripper shoe; Fixed strip is arranged on the below of slide bar.
Fixed strip is L shape.
The opening of the L shape of fixed strip is for arrange upward.
Slide bar is cylindrical.
Present invention also offers a kind of case tube heat exchanger, comprise above-mentioned gripper shoe fixed structure, also comprise pull bar, tube sheet, heat exchanger tube; Tube sheet is two or more than two, makes keeping parallelism between heat exchanger tube; Pull bar is connected with tube sheet is vertical, to make keeping parallelism between tube sheet.
Pull bar is 4, is separately positioned on four angles of tube sheet.
Case tube heat exchanger also comprises pin or baffle plate, pin or baffle plate parallel with heat exchanger tube, heat exchanger tube is divided into two regions.
Beneficial effect of the present invention: improve gripper shoe and there is its connective stability of case tube heat exchanger and installation effectiveness.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the present invention is further elaborated.

Accompanying drawing illustrates: 1, gripper shoe; 2, pull bar; 3, pin; 3a, baffle plate; 4, slide bar; 5, fixed strip; 6, housing; 7, tube sheet; 8, heat exchanger tube.
Detailed description of the invention
As shown in Figures 1 to 3, a kind of gripper shoe fixed structure, comprises gripper shoe 1, housing 6, and described gripper shoe 1 is arranged in described housing 6, is fixedly installed slide bar 4 in gripper shoe 1, and described housing 6 madial wall is fixedly installed fixed strip 5.Slide bar 4 and fixed strip 5 resilient engagement, fix with described housing 6 to make described gripper shoe 1.When assembling assembling, first slide bar 4 is welded on the bottom of gripper shoe 1, fixed strip 5 is welded on the inner side of housing 6.Manually crawl into housing 6 inside go welding to omit, fixed strip 5 can weld near the two ends of housing 6, also can be fixed by other fixed structures certainly.The gravity that slide bar 4 applies owing to being subject to gripper shoe 1, coordinates with fixed strip 5 and produces deformation, make gripper shoe 1 relative with housing 6 fixing; Or slide bar 4 and the rigging error of fixed strip 5 owing to welding, make slide bar 4 insert from fixed strip one end when coordinating and produce deformation, make fagging 1 relative with housing 6 fixing.Instead of gripper shoe 1 directly and being directly welded to connect of housing 6 by coordinating of slide bar 4 and fixed strip 5, thus eliminate the operation of the interior welds manually climbing into housing 6, improve production efficiency; Avoid welding slag to remain in the inside of housing 6 simultaneously, improve the quality of production.
Preferably, slide bar 4 is arranged on the below of gripper shoe 1, and fixed strip 5 is arranged on the below of slide bar 4.What the solder joint between slide bar 4 and gripper shoe 1 and the solder joint between fixed strip 5 and housing 6 bore is pressure instead of pulling force, makes overall structure more stable.
Preferably, fixed strip 5 is L shape.The fixed strip of L shape can make slide bar 4, and contact surface is larger with it, and structure is more stable, and the fixed strip 5 of L shape directly can adopt angle steel simultaneously, and cost of manufacture is low.
Preferably, the opening of the L shape of fixed strip 5 is for arrange upward.Slide bar 4 snaps in rear three equal Constraineds in direction from opening, and it coordinates more tight, and structure is more stable.
Preferably, described slide bar 4 is cylindrical.When assembling, can conveniently insert the cooperation position of fixed strip 5 from axial direction.
As shown in Figure 4, present invention also offers a kind of case tube heat exchanger, comprise above-mentioned gripper shoe fixed structure, also comprise pull bar 2, tube sheet 7, heat exchanger tube 8.Tube sheet 7 is two or more than two, and the effect of its fixing heat exchanger tube 8 of tube sheet 7, makes keeping parallelism between described heat exchanger tube 8; And pull bar 2 is connected with tube sheet 7 is vertical, makes to form an entirety between polylith tube sheet 7, and make keeping parallelism between tube sheet 7; Ensure that the integrally-built stability of case tube heat exchanger.
Preferably, pull bar 2 quantity is 4, is separately positioned on four angles of described tube sheet 7, makes the structure between tube sheet 7 more stable.
Preferably, case tube heat exchanger also comprises pin 3 or baffle plate 3a, described pin 3 or baffle plate 3a parallel with described heat exchanger tube 8, described heat exchanger tube 8 is divided into two regions.
Such scheme makes the structure of case tube heat exchanger gripper shoe more stable, reaches again technique effect that is convenient for assembly, that enhance productivity.
The above embodiment only have expressed comparatively concrete embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
