Description

Technical Field

[0001] This utility model relates to the field of condenser pipe hoisting technology, and in particular to a central air conditioning condenser pipe hoisting assembly. Background Technology

[0002] In a central air conditioning system, the condenser pipe plays a crucial role in dissipating the heat generated during the cooling process, and its installation quality directly affects the operating efficiency and stability of the entire system.

[0003] Traditional hanging systems typically use hangers and pipe clamps to directly fix condenser pipes to the building structure. This rigid connection method cannot effectively buffer the high-frequency vibrations generated by the compressor, fan, and other components during air conditioner operation, causing continuous friction between the pipes and the fixing components. This can easily lead to problems such as damage to the outer insulation layer of the condenser pipes and loose pipe joints causing leaks. Furthermore, exposed pipes lack effective protection, posing a risk of burns, frostbite, or pipe damage from accidental contact or impact. In addition, traditional hangers use multi-segment installation, which is cumbersome, requiring repeated positioning, welding, and adjustments, severely impacting construction efficiency. Moreover, if the hanger spacing is not properly set, the point-to-point connection between the hanger and the pipe can easily cause localized pipe sagging, altering the preset drainage slope, resulting in condensate retention, poor drainage, and even backflow, leading to damage to indoor equipment and threatening building safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a central air conditioning condenser pipe mounting assembly. It solves the technical problems of existing technologies being unable to effectively buffer the vibrations generated by air conditioning operation, leading to pipe friction damage, and the cumbersome and inefficient multi-segment installation of the hangers. The point-to-point connection method is also prone to causing local pipe sagging, resulting in condensate backflow. The assembly achieves the purpose of buffering the vibrations received by the pipes and maintaining the pipe slope to prevent condensate backflow.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a central air conditioning condenser pipe hoisting assembly, including partition plates arrayed and installed in a cable tray, a top cover hinged to the cable tray, matching locking fasteners installed on the top cover and the side of the cable tray, bases installed at the bottom of the pipe cavities separated by the partition plates in the cable tray, top seats matching the bases arrayed on the top cover, rubber pads installed on the inner surfaces of the bases and top seats, an adaptive mechanism for clamping and fixing condenser pipes of different diameters is provided between the top cover and the top seats, a slope adjustment mechanism for adjusting the slope of the condenser pipes is provided on the base, and a hoisting mechanism for quick hoisting is provided on the cable tray.

[0006] A further improvement is that the adaptive mechanism includes a buffer spring installed between the top cover and the top seat, a sleeve installed on the top cover and inside the buffer spring, and a piston rod with its bottom connected to the top seat is slidably connected inside the sleeve.

[0007] A further improvement is that the bottom of the sleeve has a ring-shaped array of damping holes with a tapered structure that is wider on the inside and narrower on the outside.

[0008] A further improvement is that the slope-making mechanism includes a connecting rod that connects adjacent bases in series and extends to the outside of the cable tray. The two ends of the connecting rod are symmetrically equipped with locking blocks that abut against the outer surface of the cable tray. A handle is provided on the outside of the locking block. A tension spring is installed between the locking block and the handle. A plug rod is installed on the handle, located inside the tension spring and inserted into the plug hole opened on the locking block.

[0009] A further improvement is that both the cable tray and the partition plate are provided with strip grooves adapted to the connecting rods, and the cable tray has symmetrically arranged insertion holes on both sides of the strip grooves adapted to the insertion rods.

[0010] A further improvement is that the hoisting mechanism includes a connecting seat installed on the outside of the cable tray, an adjusting rod installed on the connecting seat, a telescopic sleeve sleeved on the adjusting rod, a hoisting plate installed on the top of the telescopic sleeve, and locking bolts installed in the adjusting holes vertically arrayed on the bottom of the telescopic sleeve and the adjusting rod.

[0011] By employing the above technical solution, this utility model provides a central air conditioning condenser pipe hoisting assembly, which has at least the following beneficial effects:

[0012] 1. This utility model facilitates the wiring and installation of condenser tubes through the opening and closing top cover, and the partition plate divides the cable tray into multiple chambers, which facilitates the simultaneous hoisting and wiring of multiple condenser tubes. The base and top seat clamp and fix the condenser tubes, thereby completing the quick installation and fixation of the condenser tubes. The rubber pad can avoid damage to the condenser tubes caused by rigid contact and can also absorb some of the vibration of the condenser tubes.

[0013] 2. This utility model involves pulling the handle backward to stretch the tension spring and pull the plug rod out of the plug hole. Then, the handle is moved upward, causing the connecting rod and the base connected to it to move upward along the strip groove to the required height. After releasing the handle, the tension spring returns to its original position, causing the plug rod to be reinserted into the plug hole. This creates a height difference between the two ends of the condenser tube, constructing a slope for water flow and thus preventing the backflow of condensate.

[0014] 3. This utility model allows the adjusting rod to slide out of the telescopic sleeve to the desired height by pulling it, and then the locking bolt is screwed into the adjusting hole to fix the height. This enables targeted adjustment of condenser tubes at different installation heights, improving the versatility of the device and making installation more convenient and faster, thus improving construction efficiency.

[0015] 4. This utility model uses the vibration of the condenser tube to drive the piston rod to slide up and down inside the sleeve, and squeezes the gas inside the sleeve out through the damping hole. Since the damping hole is a conical structure that is wider inside and narrower outside, the air discharge is subject to throttling resistance, forming air damping. When the piston rod returns to its original position, a negative pressure is formed inside the sleeve, which draws in outside air and forms reverse air damping. Combined with the buffer spring, this further absorbs and reduces the vibration of the condenser tube. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Current technologies are ineffective at buffering vibrations generated by air conditioner operation, leading to pipe friction damage. Furthermore, multi-section installation of the hangers is cumbersome and inefficient, and point-to-point connections can cause partial pipe sagging, resulting in condensate backflow. This embodiment provides a central air conditioning condensate pipe mounting assembly that can buffer vibrations to the pipes and maintain their slope, preventing condensate backflow. Please refer to... Figures 1-6 The central air conditioning condenser pipe hoisting assembly includes partition plates 2 arrayed within a cable tray 1, a top cover 3 hinged to the cable tray 1, and matching locking fasteners 31 installed on the top cover 3 and the side of the cable tray 1. Bases 4 are installed at the bottom of the pipe cavities separated by the partition plates 2 within the cable tray 1. Top mounts 5, matching the bases 4, are arrayed on the top cover 3. Rubber pads 6 are installed on the inner surfaces of both the bases 4 and the top mounts 5. An adaptive mechanism 7 for clamping and fixing condenser pipes of different diameters is provided between the top cover 3 and the top mounts 5. A mechanism for clamping and fixing the condenser pipes is provided on the base 4. The slope adjustment mechanism 8 and the cable tray 1 are equipped with a hoisting mechanism 9 for quick installation. After opening the top cover 3, the condenser pipe is placed directly into the rubber pad 6 on the base 4. The cable tray 1 is divided into multiple chambers by the partition plate 2, which facilitates the simultaneous hoisting and routing of multiple condenser pipes. Then, the top cover 3 is closed, and the base 4 at the bottom cooperates with the top seat 5 to clamp and fix the condenser pipe, thereby completing the quick installation and fixation of the condenser pipe. The rubber pad 6 can avoid damage to the condenser pipe caused by rigid contact and can absorb some of the vibration of the condenser pipe.

[0031] Since the condenser pipe needs to have a certain slope when draining water to facilitate the flow and discharge of condensate and prevent backflow of condensate, the device is also equipped with a slope mechanism 8. The slope mechanism 8 includes a connecting rod 81 that connects adjacent bases 4 in series and extends to the outside of the cable tray 1. The two ends of the connecting rod 81 are symmetrically equipped with locking blocks 82 that abut against the outer surface of the cable tray 1. A handle 83 is provided on the outside of the locking block 82. A tension spring 84 is installed between the locking block 82 and the handle 83. A plug rod 85 is installed on the handle 83, located inside the tension spring 84 and inserted into the plug hole opened on the locking block 82.

[0032] Both the cable tray 1 and the partition plate 2 are provided with strip grooves that are compatible with the connecting rod 81. The cable tray 1 has symmetrically arranged insertion holes on both sides of the strip grooves that are compatible with the insertion rod 85. Pulling the handle 83 backward stretches the tension spring 84 and pulls the insertion rod 85 out of the insertion hole. Then, moving the handle 83 upward causes the connecting rod 81 and the base 4 connected to it to move up along the strip groove to the required height. Then, releasing the handle 83 causes the tension spring 84 to reset under its own elasticity and drive the insertion rod 85 to re-insert into the insertion hole, thereby creating a height difference between the two ends of the condenser tube and constructing a drainage slope, thus preventing the phenomenon of condensate backflow.

[0033] Because different construction environments have different requirements for the height of condensate pipe hoisting, targeted adjustments are needed according to the construction site. Therefore, the device is also equipped with a hoisting mechanism 9. The hoisting mechanism 9 includes a connecting seat 91 installed on the outside of the cable tray 1. An adjusting rod 92 is installed on the connecting seat 91. A telescopic sleeve 93 is sleeved on the adjusting rod 92. A hoisting plate 94 is installed on the top of the telescopic sleeve 93. Locking bolts 95 are installed in the vertically arrayed adjustment holes on the bottom of the telescopic sleeve 93 and the adjusting rod 92. The hoisting plate 94 is hoisted to the top of the wall. Then, according to the height of the condensate pipe, the adjusting rod 92 is pulled to slide out of the telescopic sleeve 93 to the required height. Then, the locking bolts 95 are screwed into the adjustment holes to fix the height. This allows for targeted adjustment of condensate pipes at different installation heights, improving the versatility of the device and making installation more convenient and faster, thus improving construction efficiency.

[0034] Example 2

[0035] Because the specifications and diameters of condenser tubes vary, in order to improve the versatility of the device, based on Embodiment 1, as follows: Figures 1-6 As shown, the device is also equipped with an adaptive mechanism 7, which includes a buffer spring 71 installed between the top cover 3 and the top seat 5. A sleeve 72 is installed on the top cover 3 and inside the buffer spring 71. A piston rod 73 with its bottom connected to the top seat 5 is slidably connected inside the sleeve 72. When facing condenser tubes of different diameters, the top cover 3 is closed. At this time, the top seat 5 is in contact with the top of the condenser tubes of different diameters. The reaction force generated then pushes the top seat 5 to compress the buffer spring 71 and squeezes the piston rod 73 to slide into the sleeve 72 until the top seat 5 and the base 4 cooperate to squeeze and fix the condenser tubes of different diameters, thereby improving the applicability of the device.

[0036] To further improve the buffering effect on the vibration of the condenser tube, the bottom of the sleeve 72 in this device has a ring-shaped array of damping holes 74 with a tapered structure that is wider inside and narrower outside. When the condenser tube vibrates, the vibration force drives the top seat 5 to repeatedly compress the buffer spring 71. During this process, the piston rod 73 slides up and down inside the sleeve 72 and squeezes the gas inside the sleeve 72 through the damping holes 74 to be discharged. Since the damping holes 74 have a tapered structure that is wider inside and narrower outside, the air outlet cross-sectional area is small when the air is squeezed out. The air discharge is subject to throttling resistance, forming air damping. When the piston rod 73 returns to its original position, a negative pressure is formed inside the sleeve 72, which draws in outside air and forms reverse air damping. This, together with the buffer spring 71, further absorbs and reduces the vibration of the condenser tube.
