To sum up, providing a kind of is that those skilled in the art are badly in need of the technical problem solving without the gripper shoe fixed structure being welded and fixed in the middle part of enclosure interior.
Utility model content
The problem existing based on background technology, the utility model provides a kind of gripper shoe fixed structure, fixes to realize the installation facilitating between gripper shoe and housing.
The gripper shoe fixed structure providing for realizing the utility model object, comprises gripper shoe, housing, and gripper shoe is arranged in housing, and gripper shoe is fixedly installed slide bar, on housing madial wall, is fixedly installed fixed strip; Slide bar and fixed strip resilient engagement, so that gripper shoe and housing fix.
Slide bar is arranged on the below of gripper shoe; Fixed strip is arranged on the below of slide bar.
Fixed strip is L shaped.
The opening of the L shape of fixed strip is for arranging upward.
Slide bar is cylindrical.
The utility model also provides a kind of case tube heat exchanger, comprises above-mentioned gripper shoe fixed structure, also comprises 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, so that 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, and pin or baffle plate are parallel with heat exchanger tube, and heat exchanger tube is divided into two regions.
The beneficial effects of the utility model: improve gripper shoe and there is connective stability and the installation effectiveness of its case tube heat exchanger.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with concrete drawings and the specific embodiments, the utility model is further elaborated.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is another structural representation of the utility model embodiment.
Fig. 3 is the structure enlarged diagram of A part in Fig. 1.
Fig. 4 is the structural representation of the utility model embodiment case tube heat exchanger.
Accompanying drawing explanation: 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.
The specific embodiment
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, on described housing 6 madial walls, is fixedly installed fixed strip 5.Slide bar 4 and fixed strip 5 resilient engagement, so that described gripper shoe 1 fixes with described housing 6.In the time of assembling assembling, first slide bar 4 is welded on to the bottom of gripper shoe 1, fixed strip 5 is welded on the inner side of housing 6.Manually to crawl into housing 6 inside and go welding in order to omit, fixed strip 5 can weld near the two ends of housing 6, also can be fixed by other fixed structures in the middle part of certain.Slide bar 4, due to the gravity that is subject to gripper shoe 1 and applies, coordinates with fixed strip 5 and produces deformation, makes gripper shoe 1 relative with housing 6 fixing; Or slide bar 4 and the rigging error of fixed strip 5 due to welding, make slide bar 4 insert while cooperation and produce deformation from fixed strip one end, makes fagging 1 relative with housing 6 fixing.By slide bar 4 and coordinating of fixed strip 5 having substituted gripper shoe 1 directly and being directly welded to connect of housing 6, thereby omit the operation that manually climbs into the interior welds of housing 6, improved production efficiency; Avoid welding slag to remain in the inside of housing 6 simultaneously, improved 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 the solder joint between slide bar 4 and gripper shoe 1 and fixed strip 5 and housing 6 bore is pressure rather than pulling force, makes overall structure more stable.
Preferably, fixed strip 5 is L shaped.L shaped fixed strip can make slide bar 4, and contact-making surface is larger with it, and structure is more stable, and L shaped fixed strip 5 can directly adopt angle steel simultaneously, and cost of manufacture is low.
Preferably, the opening of the L shape of fixed strip 5 is for arranging upward.Slide bar 4 is three equal Constraineds of direction from opening snaps in, and its cooperation is tightr, and structure is more stable.
Preferably, described slide bar 4 is cylindrical.In the time of assembling, can conveniently insert the cooperation position of fixed strip 5 from axial direction.
The utility model also provides a kind of case tube heat exchanger, comprises above-mentioned gripper shoe fixed structure, also comprises pull bar 2, tube sheet 7, heat exchanger tube 8.Tube sheet 7 is two or more than two, and the effect of tube sheet 7 its fixing heat exchanger tubes 8 makes keeping parallelism between described heat exchanger tube 8; And pull bar 2 is connected with tube sheet 7 is vertical, makes to form between polylith tube sheet 7 entirety, and make keeping parallelism between tube sheet 7; Guarantee the integrally-built stability of case tube heat exchanger.
Preferably, pull bar 2 quantity are 4, are separately positioned on four angles of described tube sheet 7, make the structure between tube sheet 7 more stable.
Preferably, case tube heat exchanger also comprises pin 3 or baffle plate 3a, and described pin 3 or baffle plate 3a are parallel with described heat exchanger tube 8, and 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 convenient for assembly, that enhance productivity.
The above embodiment has only expressed comparatively concrete embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
