Description

Technical Field

[0001] The utility model relates to the technical field of cold machine maintenance, in particular to a cold machine end cover positioning structure which is convenient for clamping and fixing. Background Art

[0002] The water-cooled chiller (referred to as the chiller) is the core equipment of the central air-conditioning system. The basic structure includes a compressor, a condenser, a shut-off device, and an evaporator. Among them, the condenser and the evaporator use shell and tube heat exchangers. Cooling water flows in the tube of the condenser, and chilled water flows in the tube of the evaporator. Both cooling water and chilled water contain dirt, impurities, and components such as calcium and magnesium ions that are prone to scaling. When scaling in the tube is serious, it will significantly affect the heat exchange capacity of the condenser and evaporator, and reduce the operating efficiency and effect of the chiller. In order to solve the scaling problem in the tube, the condenser and evaporator of the chiller need to be cleaned regularly, and the first step of cleaning is to remove the end covers of the condenser and evaporator.

[0003] Traditional refrigerators cannot achieve the requirement of rapid disassembly and assembly of refrigerator end covers during cleaning, which is a great obstacle to rapid maintenance of refrigerators. Therefore, the purpose of the utility model is to achieve rapid disassembly and assembly of refrigerator end covers and improve the efficiency of daily maintenance and cleaning.

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0028] Embodiment 1: A positioning structure for a cold machine end cover that is convenient for clamping and fixing, such as Figure 1 and Figure 2As shown, it includes a base 1, a positioning plate 2, a longitudinal slide rail 11 and a transverse slide rail 12 arranged vertically and staggered, the longitudinal slide rail 11 is fixedly connected to the base 1, a clamping assembly is provided on one side of the positioning plate 2, and the other side of the positioning plate 2 is fixedly connected to a telescopic rod 21 slidably provided on the longitudinal slide rail 11, that is, the left end of the telescopic rod 21 is a telescopic end fixedly connected to the other side of the positioning plate 2, and the right end of the telescopic rod 21 is a fixed end and is slidably connected to the longitudinal slide rail 11 up and down, a first threaded rod 111 is threadedly sleeved on the telescopic rod 21 and is rotatably connected to the longitudinal slide rail 11, the longitudinal slide rail 11 is fixedly connected to a slider 112 slidably provided on the transverse slide rail 12, and a second threaded rod 121 is threadedly sleeved on the slider 112 and is rotatably connected to the transverse slide rail 12; the transverse slide rail 12 is fixedly connected to the base 1 through a connecting rod;

[0029] like Figure 1 As shown, two clamping assemblies are symmetrically provided, and the clamping assemblies include a clamping plate 22 and a first driving structure for driving the clamping plate 22 to slide. The first driving structure adopts existing technology, such as an electric telescopic rod, and the electric telescopic rod is fixedly set on the positioning plate 2.

[0030] The working principle of the above-mentioned cold machine end cover positioning structure is: fix the base 1 in front of the end cover, then adjust the height of the positioning plate 2 by rotating the first threaded rod 111 and adjust the left and right position of the positioning plate 2 by rotating the second threaded rod 121, so that the center of the positioning plate 2 is aligned with the lifting ring in the center of the end cover; then drive the telescopic rod 21 to make the positioning plate 2 approach the end cover until the positioning plate 2 and the end cover are in contact, then stop approaching, and drive the electric telescopic rod to clamp the clamping plate 22 to the side wall of the end cover to clamp and fix the end cover, and then retract the telescopic rod 21 to make the positioning plate 2 and the clamping plate 22 synchronously drive the end cover to move backward to remove the end cover.

[0031] Embodiment 2: This embodiment differs from Embodiment 1 in that Figure 3 to Figure 5 As shown, two auxiliary structures for assisting the clamping assembly to be fixed are symmetrically arranged on the positioning disk 2, the auxiliary structures include a gusset plate 23 connected to the positioning disk 2 in an upward and downward sliding manner, a central axis rotatably arranged on the flange of the gusset plate 23, a transmission shaft 232 connected to one end of the central axis with a transmission, and a third threaded rod 233 connected to the transmission shaft 232 with a transmission, the third threaded rod 233 is threadedly connected to the gusset plate 23, and the third threaded rod 233 is rotatably connected to the positioning disk 2, the transmission shaft 232 is rotatably connected to the top of the gusset plate 23, and a roller 231 is arranged at the other end of the central axis; magnets that attract each other are respectively arranged on the two gusset plates 23;

[0032] like Figure 4-5 As shown, the positioning plate 2 is provided with a rotating wheel 235 for connecting the transmission shaft 232 and the third threaded rod 233 with a belt transmission, and a fixing plate 236 rotatably connected to the rotating wheel 235 is fixedly provided on the buckle plate 23 .

[0033] The working principle of this embodiment is different from that of embodiment 1 in that when the positioning plate 2 is close to the lifting ring, the roller 231 on the buckle plate 23 rotates due to the friction between the lifting ring and the buckle plate 231, and the roller 231 drives the third threaded rod 233 to rotate via the transmission shaft 232, so that the third threaded rod 233 drives the upper buckle plate 23 to descend and the lower buckle plate 23 to move up, so that when passing through the lifting ring and then entering the lifting hole, the buckle plates 23 on both sides are fitted and fastened, so that after clamping and fixing, more and more stable disassembly force is further applied to the end cover by fastening the lifting ring; after the disassembly is completed, the third threaded rod 233 and the telescopic rod 21 are rotated in the opposite direction to release the end cover.

[0034] Embodiment 3: This embodiment differs from Embodiment 2 in that Figure 6 As shown, the first driving structure includes a spring rod 221 for connecting the clamping plate 22 and the positioning plate 2, a fourth threaded rod 222 with one end threadedly connected to the clamping plate 22, and a second driving structure for driving the fourth threaded rod 222 to rotate and disengage from the clamping plate 22, and the other end of the fourth threaded rod 222 is slidably connected to the positioning plate 2; and the spring rod 221 is always in a contracted state during the clamping process of the clamping plate 22;

[0035] like Figure 7 As shown, the second drive structure adopts existing technology, such as a rotating motor; as an example, the second drive structure includes a first gear 223 threadedly mounted on the fourth threaded rod 222, a second gear 234 fixedly mounted on the third threaded rod 233, and a toothed plate 224 meshing with both the first gear 223 and the second gear 234, the first gear 223 is rotatably connected to the positioning plate 2, and the toothed plate 224 is slidably connected to the positioning plate 2.

[0036] The working principle of this embodiment is different from that of the first embodiment in that when the buckle plate 23 is buckled, the third threaded rod 233 drives the toothed plate 224 to translate, thereby driving the fourth threaded rod 222 to rotate, so that the fourth threaded rod 222 is separated from the clamping plate 22 during the movement, so that the clamping plate 22 approaches the end cover under the contraction of the spring rod 221 and clamps the end cover;

[0037] When the disassembly is completed, the clamping plate 22 is first stretched back, and then the third threaded rod 233 is rotated in the opposite direction to make the fourth threaded rod 222 extend out and engage with the clamping plate 22, so that the clamping plate 22 is restored to a fixed state.
