Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment, and in particular to a support mechanism and a hoisting device for the end cover of a chiller unit. Background Technology

[0002] Chillers are common refrigeration equipment in buildings and are the core of air conditioning systems. They mainly consist of compressors, condensers, evaporators, and expansion valves. Among these, the chiller end cap is one of the important internal components, responsible for sealing off the various components inside the unit to ensure its normal operation.

[0003] During equipment operation and maintenance, the units frequently require repair and upkeep. One of the most frequent tasks is the disassembly and installation of the chiller unit's end caps. Due to the large size and heavy weight of the chiller unit end caps, it generally requires the cooperation of multiple people. By erecting scaffolding and using manual chain hoists, the end caps can be hoisted, which is difficult and poses certain safety hazards. Some systems use welded hangers on the side of the end cap for hoisting. However, this fixed installation method makes it difficult to remove the hangers, and each end cap needs to be equipped with one, resulting in high costs. Furthermore, the disassembly and installation of end caps for condensers, evaporators, etc., of various chiller models requires the design of multiple hangers with different opening angles, resulting in low hanger versatility and high design costs. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is: how to provide a hanger that is easy to disassemble and is applicable to various models of chiller units.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a support mechanism, including: an installation component, the installation component including two mounting seats arranged in the same row, and a mounting plate hinged to the mounting seats; and a bracket assembly, the bracket assembly including support legs detachably mounted on the mounting plate at their lower ends, and the upper ends of the two support legs being hinged to the same crossbeam.

[0006] In a preferred embodiment of the support mechanism of this utility model: the mounting assembly further includes an ear plate disposed on the mounting base, a top rod threadedly connected to the ear plate, a top block disposed at one end of the top rod near the mounting plate, and the top block being located between the mounting plate and the mounting base.

[0007] In a preferred embodiment of the support mechanism of this utility model: the mounting base is an inverted U-shaped structure, and the mounting plate is hinged to the upper end surface of the mounting base.

[0008] In a preferred embodiment of the support mechanism of this utility model: a sleeve is provided on the side of the mounting plate away from the mounting seat, and the lower end of the support leg extends into the sleeve.

[0009] In a preferred embodiment of the support mechanism described in this utility model: a positioning pin is provided between the sleeve and the support leg.

[0010] In a preferred embodiment of the support mechanism of this utility model: a connecting part is provided at one end of the cross frame near the support leg, the cross section of the connecting part is circular, a first rotating cylinder and a second rotating cylinder are rotatably sleeved on the connecting part, and the ends of the two support legs away from the mounting plate are respectively fixed on the first rotating cylinder and the second rotating cylinder.

[0011] In a preferred embodiment of the support mechanism of this utility model: there are two first rotating cylinders, and a second rotating cylinder is disposed between the two first rotating cylinders. A connecting plate is disposed between the two first rotating cylinders, one of the supporting legs is connected to the connecting plate, and the other supporting leg is connected to the outer wall of the second rotating cylinder.

[0012] In a preferred embodiment of the support mechanism of this utility model: the bracket assembly further includes a hanging plate movably disposed on the cross frame, and the hanging plate is provided with hook holes.

[0013] In a preferred embodiment of the support mechanism described in this utility model, the bracket assembly further includes baffles disposed at both ends of the crossbeam.

[0014] The beneficial effects of this utility model are as follows: Since the support mechanism adopts a detachable combination of installation components and bracket components, the bracket component can be detachably installed. After the end cover is hoisted, the bracket component can be removed and placed or the next end cover can be hoisted. Only one bracket component is needed to complete the hoisting of multiple end covers, resulting in lower usage costs. At the same time, by hinged the upper ends of the two support legs to the crossbeam, the opening angle of the two support legs can be varied to meet the installation requirements of different distances between the two mounting seats. This allows the bracket component to be used for hoisting the end covers of condensers, evaporators, etc. of various models of chiller units, eliminating the need to design different opening angle hangers for each model of condenser and evaporator end cover, thus reducing design costs.

[0015] To address the technical problem of inconvenient disassembly of chiller unit end cover hoisting equipment in existing technologies, this utility model also proposes a chiller unit end cover hoisting device. The aforementioned support mechanism further includes an electric hoist, which is hung on a crossbeam.

[0016] The beneficial effects of this utility model are as follows: This hoisting device is easy to assemble and disassemble because it adopts a detachable combination design of support components and installation components. Attached Figure Description

[0024] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0026] Reference Figure 1 , refer to Figures 1 to 4 This embodiment provides a support mechanism, including:

[0027] Mounting component 1 includes two mounting bases 11 arranged in the same row, and mounting plates 12 are hinged to the mounting bases 11.

[0028] The bracket assembly 2 includes a support leg 21 detachably mounted on the mounting plate 12 at its lower end, and the upper ends of the two support legs 21 are hinged to the same crossbar 22.

[0029] Mounting component 1 is used to fix the entire support mechanism to the vicinity of the end cover to be hoisted on the vertical plate 9 of the chiller unit. Specifically, mounting base 11 is fixed to the vertical plate 9 near the end cover to be hoisted by welding. There are two mounting bases 11, which are respectively arranged near the two sides of the vertical plate 9. Each mounting base 11 is provided with mounting plate 12, which is used to install two support legs 21. Specifically, the lower ends of the two support legs 21 are detachably installed on the mounting plates 12 of the two mounting bases 11. The upper ends of the two support legs 21 are hinged to the same cross frame 22. The cross frame 22 is used to place the lifting equipment for hoisting.

[0030] In practical use, the aforementioned mounting component 1 is welded onto the upright plate 9 near each end cap to be hoisted. The bracket component 2 is detachably installed on the mounting component 1 near the end cap to be hoisted. After the end cap to be hoisted is completed, the support component is removed. When hoisting the next end cap to be hoisted, the removed bracket component 2 is installed on the mounting component 1 near the end cap to be hoisted, and the hoisting of the end cap to be hoisted continues. The hoisting operation of each end cap is carried out in a cyclical manner. Since the support mechanism of this application adopts the detachable combination of mounting component 1 and bracket component 2, the bracket component 2 is detachably installed. After the end cap is hoisted, the bracket component 2 can be removed and placed or the next end cap can be hoisted. Only one bracket component 2 is needed to complete the hoisting of multiple end caps, resulting in low usage costs.

[0031] Meanwhile, for various models of chiller units, the end caps of condensers and evaporators are of different sizes, and the welding distances of the two mounting seats 11 on the mounting seat 9 are also different. This application hinges the upper ends of the two support legs 21 to the cross frame 22, so that the opening angle of the two support legs 21 can be changed to meet the installation requirements of the two mounting seats 11 at different distances. Thus, the bracket assembly 2 is suitable for hoisting the end caps of condensers and evaporators of various models of chiller units. It is not necessary to design different opening angles for each model of condenser and evaporator end cap, thus reducing design costs.

[0032] Furthermore, refer to Figure 2 and Figure 3 The mounting assembly 1 also includes an ear plate 13 disposed on the mounting base 11. A push rod 14 is threadedly connected to the ear plate 13. A push block 15 is disposed at one end of the push rod 14 near the mounting plate 12. The push block 15 is located between the mounting plate 12 and the mounting base 11.

[0033] The support leg 21 has a certain tilt angle, and the mounting plate 12 is tilted accordingly. This results in a certain gap between the mounting plate 12 and the top surface of the mounting base 11. This gap may affect the hoisting stability. The top block 15 is designed to be placed between the mounting plate 12 and the mounting base 11, and the top block 15 is pressed tightly by the top rod 14 to ensure the hoisting stability.

[0034] Furthermore, refer to Figure 2 and Figure 3 The mounting base 11 has an inverted U-shaped structure, and the mounting plate 12 is hinged to the upper end surface of the mounting base 11.

[0035] The mounting base 11 is specifically a U-shaped structure that adapts to the vertical plate 9 near the end cover to be hoisted. When the mounting base 11 is fixed on the vertical plate 9, the mounting base 11 is inserted upside down into the vertical plate 9 and then fixed by welding.

[0036] Furthermore, refer to Figure 2 and Figure 3 A sleeve 16 is provided on the side of the mounting plate 12 away from the mounting base 11. The lower end of the support leg 21 extends into the sleeve 16. A positioning pin 17 is provided between the sleeve 16 and the support leg 21.

[0037] The support leg 21 is detachably connected to the mounting plate 12 via the sleeve 16. Specifically, the sleeve 16 is fixed on the mounting plate 12. The inner hole of the sleeve 16 is adapted to the support leg 21. For example, if the support leg 21 is a round rod, the inner hole of the sleeve 16 is a round hole with the same diameter as or slightly larger than the diameter of the round rod. When the bracket assembly 2 is installed, the lower end of the support leg 21 is inserted into the sleeve 16 and then fixed by the positioning pin 17. The bracket assembly 2 is detachable. The positioning pin 17 is pulled out, and then the support leg 21 is pulled out from the sleeve 16. Both disassembly and assembly are relatively convenient.

[0038] Example 2, refer to Figure 4 and Figure 5 The cross frame 22 is provided with a connecting part 221 at one end near the support leg 21. The cross section of the connecting part 221 is circular. A first rotating cylinder 222 and a second rotating cylinder 223 are rotatably sleeved on the connecting part 221. The ends of the two support legs 21 away from the mounting plate 12 are respectively fixed on the first rotating cylinder 222 and the second rotating cylinder 223.

[0039] The crossbar 22 is specifically a round rod. The connecting part 221 is integrally set at the end of the crossbar 22, with a diameter smaller than that of the round rod end of the crossbar 22. A first rotating cylinder 222 and a second rotating cylinder 223 are rotatably sleeved on the round rod end, which are used for the hinge connection between the two support legs 21 and the crossbar 22, respectively. Specifically, there are two first rotating cylinders 222, and the second rotating cylinder 223 is set between the two first rotating cylinders 222. A connecting plate 224 is set between the two first rotating cylinders 222. One support leg 21 is connected to the connecting plate 224, and the other support leg 21 is connected to the outer wall of the second rotating cylinder 223. The opening and closing angle between the two support legs 21 can be adjusted by rotating the first rotating cylinder 222 and the second rotating cylinder 223 relative to the crossbar.

[0040] Furthermore, refer to Figure 4 The bracket assembly 2 also includes a hanging plate 23 movably mounted on the cross frame 22, and the hanging plate 23 is provided with a hook hole 231.

[0041] The hanging plate 23 has a through hole, the shape of which matches the shape of the cross frame 22 and the size of which is larger than the outer diameter of the cross frame 22. The cross frame 22 passes through the through hole on the hanging plate 23, so that the hanging plate 23 can be movably fitted on the cross frame 22. The hanging plate 23 is flexible in position and easy to hoist. The hanging plate 23 has a hook hole 231 for installing a lifting device for the end cap.

[0042] Furthermore, refer to Figure 4 and Figure 5 The support assembly 2 also includes baffles 24 disposed at both ends of the crossbeam 22.

[0043] The baffle 24 is provided to prevent the first rotating drum 222, the second rotating drum 223 and the lifting device from detaching from the end of the crossbeam 22.

[0044] Example 3, referring to Figure 6 A chiller unit end cover hoisting device includes the aforementioned support mechanism and also includes an electric hoist 3, which is hung on a crossbeam 22.

[0045] The hoisting device uses the aforementioned support mechanism as its support base. An electric hoist 3 is hung on this support base to form a hoisting device for the end cover. The electric hoist 3 is specifically hung at the hook hole 231 of the hanging plate 23. During hoisting, the aforementioned support mechanism is installed on the upright plate 9 near the end cover to be hoisted. The electric hoist 3 is hung on the hanging plate 23, and the hoisting end (usually the hook) of the electric hoist 3 is connected to the lifting ring of the end cover to be hoisted. The electric hoist 3 works to perform the hoisting. After the hoisting is completed, the electric hoist 3 is removed, and then the bracket assembly 2 of the support mechanism can be disassembled. The hoisting device of this application adopts a detachable combination design of the bracket assembly 2 and the installation assembly 1, which makes disassembly and assembly relatively convenient.

[0046] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
