[0057] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0058] like Figures 1 to 11As shown, an embodiment of the present invention provides a special disassembly tool for the end cover of a refrigerator heat exchanger, which includes a cantilever 100, a first support rod 200, a second support rod 300 and a support mechanism 400; a support portion 110 is provided at one end of the cantilever 100, and the support portion 110 protrudes from the surface of the cantilever 100, and the other end of the cantilever 100 is used to be connected to the cylinder 10 of the water chamber; one end of the first support rod 200 and the second support rod 300 are both connected to the cantilever 100, and the other end of the second support rod 300 is connected to the other end of the first support rod 200, and a triangular structure is formed between the first support rod 200, the second support rod 300 and the cantilever 100; the support mechanism 400 is connected to an end of the second support rod 300 away from the cantilever 100, and is used to be supported on the port 11 of the cylinder 10.
[0059] The existing water chamber is generally assembled by a cylinder 10 and an end cover 20. Copper tubes for heat exchange are arranged inside the cylinder 10, and both ends of the cylinder 10 are sealed by the end covers 20. In order to facilitate large-scale hoisting during the installation of the water chamber, a flange 12 is generally provided on the cylinder 10, so that the hoisting equipment can hoist the cylinder 10 equipped with the end cover 20.
[0060] It is understandable that after long-term heat exchange, the copper tube is prone to scaling. After scaling, the end cover 20 needs to be removed to clean the internal scaling. However, due to the heavy weight of the end cover 20, it cannot be directly removed. It is necessary to temporarily build a gantry on the ground to hoist the end cover 20. This process wastes manpower and reduces work efficiency.
[0061] To this end, this embodiment designs a special disassembly tool for the end cover of the heat exchanger of the refrigerator based on the structural characteristics of the cylinder 10 to replace the existing gantry. Specifically, during the working process, one end of the cantilever 100 can be directly fixed on the flange 12 on the cylinder 10, and the support mechanism 400 can be abutted against the port 11 of the cylinder 10. The disassembly tool itself has a structural support feature that is approximately triangular, so that the disassembly tool can have a stable support posture. Since the support part 110 on the cantilever 100 protrudes from the surface of the cantilever 100, the support part 110 can be aligned with the end cover 20 below, and the support part 110 can be aligned with the center of the end cover 20 below in the vertical direction. Therefore, the middle part of the rope used for lifting can pass around the support part 110, and the two ends of the rope are respectively fixed with hooks on both sides of the end cover 20, so that the lifting of the end cover 20 can be achieved without building a gantry.
[0062] Compared with the prior art, the special disassembly tool for the end cover of the refrigerator heat exchanger provided in this embodiment can be directly connected to the structural characteristics of the water chamber itself, without the need to temporarily build a gantry for disassembling the end cover 20, thereby effectively improving the working efficiency. At the same time, the disassembly tool can be operated by only one person, thereby saving manpower and reducing labor intensity.
[0063] The end cover 20 may also be provided with a flange 21 , and the edge of the flange 21 may be symmetrically provided with slots 22 , so that the hooks at both ends of the rope can be engaged with the slots 22 to fix and hoist the end cover 20 .
[0064] Furthermore, the disassembly tool further includes a clamping block 500, a fixing stud 180 is provided on one end of the cantilever 100, a first mounting hole 13 cooperating with the fixing stud 180 may be provided on the flange 21 on the end cover 20, and a second mounting hole 510 cooperating with the fixing stud 180 may be provided on the clamping block 500. When the disassembly tool is installed on the flange 1221 on the end cover 20, the fixing stud 180 may be passed through the first mounting hole 13 and the second mounting hole 510 in sequence, and then fastened by the locking nut 520, so that the clamping block 500 and the cantilever 100 clamp the flange 21 on the end cover 20, thereby achieving the fastening of the disassembly tool. Among them, the fixing stud 180 is provided with more than two, which can prevent the disassembly tool from rotating on the one hand, and ensure the reliability of the fastening of the disassembly tool on the other hand.
[0065] In addition, in order to facilitate the holding of the clamping block 500 during the tightening process, a handle may be provided on the clamping block 500 .
[0066] Further, if Figure 7 , Fig. 9 and Fig.10 As shown, the support portion 110 specifically includes a lifting arm 112 and a limiting structure 111 . Both ends of the lifting arm 112 are respectively connected to the cantilever 100 and the limiting structure 111 . The diameter of the limiting structure 111 is greater than the diameter of the lifting arm 112 .
[0067] Among them, the lifting arm 112 is a nearly shaft-shaped structure, so that the wear of the lifting arm 112 on the rope thereon can be reduced. At the same time, the limiting structure 111 and the cantilever 100 can limit the rope and prevent the rope from falling off the lifting arm 112.
[0068] Furthermore, a positioning hole 115 for threaded connection with the locking screw 113 is provided on the limiting structure 111 , and a key slot 114 is provided on the hanging arm 112 . The locking screw 113 passes through the positioning hole 115 and abuts against the bottom of the key slot 114 .
[0069] It can be understood that the positioning hole 115 is a threaded hole, and the locking screw 113 can be screwed in or out of the positioning hole 115. When the limiting structure 111 is sleeved on the lifting arm 112, the positioning hole 115 can be aligned with the appropriate position on the key slot 114, and then the locking screw 113 is tightened to press the locking screw 113 against the bottom of the key slot 114, so that the limiting structure 111 and the lifting arm 112 can be relatively fixed. At the same time, the limiting structure 111 can be prevented from rotating by the cooperation between the locking screw 113 and the key slot 114.
[0070] Further, if Figure 2 and Figure 5 As shown, the disassembly tool also includes a first base 120 and a connecting base 130. The first base 120 is fixedly set on the cantilever 100. An adjustment hole 121 is set in the first base 120. The connecting base 130 is rotatably set in the adjustment hole 121 through a turn pin 140; a connecting sleeve 131 is set on the connecting base 130, and one end of the first support rod 200 is fixedly set in the connecting sleeve 131.
[0071] The first base 120 is inclined at a certain angle toward the direction of the second support rod 300. When the first support rod 200 is connected to the first base 120 through the connecting seat 130, the first support rod 200 is also inclined toward the direction of the second support rod 300, so that a triangular support structure can be formed between the second support rod 300 and the cantilever 100 to ensure the reliability of the support. Figure 5 As shown, the center of the connecting seat 130 is connected to the center of the first base 120 through the rotating pin 140, and there is a gap 122 between the connecting seat 130 and the inner wall surface of the adjusting hole 121, so that the connecting seat 130 can be slightly rotated in the adjusting hole 121 to achieve a slight adjustment of the first support rod 200, thereby achieving adaptive adjustment of the first support rod 200 during the supporting process to ensure the coordination of the support.
[0072] Specifically, Figure 2 As shown, the first support rod 200 includes a first support rod 210 and a first universal connector 220, and the first support rod 210 is provided with a first stud 211 and a second stud 212 at both ends, the first stud 211 is threadedly connected to the connecting seat 130, the second stud 212 is threadedly connected to one end of the first universal connector 220, and the other end of the first universal connector 220 is connected to the second support rod 300.
[0073] The coordination of the connection position between the first support rod 200 and the second support rod 300 can be automatically adjusted by the first universal connector 220, and the overall length of the second support rod 300 can be adjusted by the first stud 211 and the second stud 212 to ensure that a stable triangular support structure is formed between the second support rod 300, the first support rod 200 and the cantilever 100.
[0074] Specifically, Figure 2 As shown, the first universal connector 220 includes a first sleeve 222 and a first adjusting bearing 221. The first sleeve 222 is provided with an internal thread, and the second stud 212 is threadedly connected to the first sleeve 222; the end of the second support rod 300 away from the cantilever 100 passes through the first adjusting bearing 221 and is connected to the supporting mechanism 400.
[0075] The second support rod 300 can rotate slightly in the first adjustment bearing 221 to automatically adjust the posture between the second support rod 300 and the first support rod 200 during operation to achieve stable support. It can be understood that, through the cooperation of the connecting seat 130 and the adjustment hole 121, the first support rod 200 can be rotated in a plane nearly parallel to the axis of the second support rod 300, and through the cooperation of the first universal connector 220 and the second support rod 300, the first support rod 200 can be rotated in a plane nearly perpendicular to the axis of the second support rod 300; thus, through the above-mentioned adaptive adjustment of the first support rod 200 and the second support rod 300, it can be ensured that the first support rod 200 and the second support rod 300 have a better support force state and ensure the support stability.
[0076] Further, if Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the disassembly tool also includes a second base 150, a universal bearing 160 and a limiting cap 170. The second base 150 is fixedly arranged on the cantilever 100. A connecting stud 151 is arranged on the second base 150. A threaded hole is arranged in the limiting cap 170. The limiting cap 170 is fixedly installed on the second base 150 by matching the connecting stud 151 and the threaded hole; the universal bearing 160 is arranged in the threaded hole, one end of the universal bearing 160 abuts against the end face of the connecting stud 151, and the end of the second support rod 300 away from the first support rod 200 extends into the threaded hole and abuts against the universal bearing 160.
[0077] The axis direction of the connecting stud 151 also forms an acute angle with the cantilever 100, so that the second support rod 300 can form a triangular structure with the first support rod 200 and the cantilever 100. It can be understood that the depth of the threaded hole in the above-mentioned limiting cap 170 is greater than the length of the connecting stud 151. When the limiting cap 170 and the connecting stud 151 are fastened, there is still a certain space in the threaded hole for fixing the universal bearing 160. The universal bearing 160 can provide support for adjusting the angle of the second support rod 300 to ensure that the second support rod 300 has a stable posture during operation.
[0078] Further, if Figure 2 , Figure 6and Figure 8 As shown, the second support rod 300 includes a second support rod 310 and an adjusting rod 320. A spherical portion 311 is provided at one end of the second support rod 310, and the spherical portion 311 abuts against the universal bearing 160, thereby ensuring that the ball can rotate smoothly. A third stud 312 is provided at the other end of the second support rod 310, and the adjusting rod 320 includes an adjusting sleeve 321. The third stud 312 is threadedly connected to the adjusting sleeve 321.
[0079] A threaded hole may be provided in the adjusting sleeve 321 , and the overall length of the first support rod 200 may be adjusted through the adjusting sleeve 321 to ensure the structural stability of the triangular structure formed by the first support rod 200 , the second support rod 300 and the cantilever 100 .
[0080] Further, if Figure 2 and Fig.11 As shown, the support mechanism 400 includes a support block 420 and a second universal connector 410, one end of the second universal connector 410 is connected to the support block 420; the adjustment rod 320 also includes a fourth stud 322, one end of the fourth stud 322 is fixedly connected to the adjustment sleeve 321, and the other end of the fourth stud 322 is connected to the other end of the second universal connector 410 after passing through the first adjustment bearing 221.
[0081] Among them, the second universal connector 410 can have the same structure as the first universal connector 220, so that the support block 420 can swing slightly at an angle relative to the second universal connector 410, thereby realizing adaptive adjustment of the support block 420 after being pressed against the water chamber end cover 20, thereby ensuring reliable support of the support block 420 on the end cover 20.
[0082] Further, if Figure 1 and Fig.11 As shown, a curved surface may be provided on a side of the support block 420 that is away from the second universal connector 410 .
[0083] Since the side surfaces of the existing end caps 20 are generally arc-shaped, in order to make the support block 420 fit closely with the end cap 20 and ensure the support stability, the support block 420 may have an arc-shaped surface that matches the side surface of the end cap 20. Of course, if the side surface of the end cap 20 is a plane, the side surface of the support block 420 that contacts the end cap 20 may also be a plane, which may be determined according to the shape of the end cap 20.
[0084] The special disassembly tool for the end cover of the refrigerator heat exchanger provided in the embodiment of the present invention can be directly connected to the structural characteristics of the water chamber itself, without the need to temporarily build a gantry for disassembling the end cover, thereby effectively improving the working efficiency. At the same time, the disassembly tool can be operated by only one person, thereby saving manpower and reducing labor intensity.
