Technical Field
[0001] This utility model relates to the technical field of air conditioning, specifically to a novel multi-functional air conditioner for a crane operator's cab. Background Technology
[0002] Multi-functional overhead cranes are specialized equipment for aluminum electrolysis production. They are primarily responsible for tasks such as shell breaking, electrode changing, aluminum tapping, material unloading, busbar lifting, and the daily hoisting of heavy objects, achieving high utilization. The operator's cab of the multi-functional overhead crane needs to be able to withstand the high-temperature molten salt, high-current, strong magnetic field, dusty, and hydrogen fluoride-rich environment of the electrolysis plant. Therefore, overhead crane manufacturers have equipped the operator's cab with air conditioning to provide a comfortable working environment for the operators.
[0003] Chinese utility model patent CN204096941U discloses a roof-mounted air conditioner for the operator's cab of a gantry crane. Two partitions are horizontally installed within an air conditioning unit corresponding to the operator's cab, dividing the unit into three installation chambers. In the left installation chamber, two condensers connected by air pipes are symmetrically installed front and rear. An exhaust fan facing upwards towards the air inlet of the air conditioning hood is installed between the two condensers. In the middle installation chamber, a compressor connected to the two condensers is installed. A liquid storage tank and a dryer are connected in series behind the rear compressor. In the right installation chamber, an evaporator connected to both the dryer and the condenser is installed in the middle. At least one exhaust fan leading from the bottom of the right installation chamber into the operator's cab is installed at the bottom. Installed on the roof of the operator's cab, this system supplies either cool or warm air to the interior, effectively maintaining a normal temperature without affecting the working space and improving the crane's efficiency.
[0004] When the air conditioner is running, the compressor generates noise and vibration, which can be quite loud in the driver's cab, potentially affecting the operator's work. Therefore, existing overhead crane driver's cab air conditioners suffer from the technical problem of excessive noise transmitted to the driver's cab. Utility Model Content
[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a new type of multi-functional crane operator's cab air conditioner, which includes an indoor unit and an outdoor unit. This new type of multi-functional crane operator's cab air conditioner has the advantages of low noise and vibration transmitted to the operator's cab.
[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0007] A novel multi-functional overhead crane operator's cab air conditioner includes an indoor unit and an outdoor unit. The outdoor unit includes a casing, a condenser, and a compressor. The compressor is fixedly mounted on a base, and the base is fixedly connected to multiple support legs. The support legs extend horizontally away from the base, and their width gradually decreases in the direction away from the base. An elastic shim is provided below each support leg, and the two ends of the elastic shim are respectively engaged with the support leg and the bottom wall of the casing. Anchor bolts are provided on each support leg, and the anchor bolts pass through the support leg, the elastic shim, and the bottom wall of the casing. Ribs are fixedly connected to the support legs and surround the elastic shim. A liquid inlet pipe is provided between the condenser and the compressor. The casing is provided with a liquid return pipe and an air inlet pipe. The liquid return pipe is connected to both the condenser and the indoor unit, and the air inlet pipe is connected to both the indoor unit and the compressor.
[0008] This design effectively reduces vibration and noise transmitted to the driver's cab through the casing by using elastic shims to absorb vibrations generated during compressor operation. Furthermore, the elastic deformation of the support legs allows them to adapt to compressor vibrations, further reducing vibrations transmitted from the base to the driver's cab, resulting in lower noise and vibration levels. Elevating the compressor with elastic shims also prevents it from being covered by dust at the bottom, ensuring stable and continuous operation within the electrolysis plant environment.
[0009] Preferably, the infusion tube has a coil structure, which is located above the compressor, and the infusion tube at the coil structure extends spirally upward in a direction away from the compressor.
[0010] With this setup, the air conditioner compressor needs to move synchronously with the driver's cab. When the driver's cab moves, the compressor will shake, causing deformation and wear at the interface between the compressor and the piping, making it prone to damage. The coil structure allows it to elastically deform with the compressor's movement, preventing excessive pressure on the compressor interface from the infusion pipes during compressor movement, thus protecting the piping.
[0011] Preferably, the compressor is fixedly connected to a support plate, the support plate is equipped with a support frame, the support frame is fixedly connected to a buffer pad, and the upper surface of the buffer pad abuts against the coil structure.
[0012] This configuration improves the stability of the coil structure.
[0013] Preferably, the support frame is fixedly connected to a clamping plate, the clamping plate is located inside the coil structure, and the clamping plate is fixedly connected to a flexible pad that abuts against the coil structure.
[0014] This configuration further enhances the stability of the coil structure.
[0015] Preferably, the support frame is provided with a through groove extending in the vertical direction, and the support plate is threaded with a screw passing through the through groove, and the screw is provided with a washer that engages with the support frame.
[0016] This setup enables the function of locking the support frame on the support plate.
[0017] Preferably, the housing is fixedly connected to a first mounting bracket, and the first mounting bracket is equipped with a first fan located at the compressor.
[0018] This setting ensures that the compressor can operate stably.
[0019] Preferably, the housing is fixedly mounted with a partition, the condenser and the compressor are located on opposite sides of the partition, and the housing is provided with a first heat dissipation window located above the compressor.
[0020] This setting improves heat dissipation.
[0021] Preferably, the casing is rotatably connected to a door, the door has an air inlet located at the first fan, the door is fixedly installed with a first mesh cover located inside the air inlet, and a dust removal groove is provided between the lower end of the door and the bottom wall of the casing.
[0022] This design effectively and sustainably prevents dust accumulation under the compressor, preventing dust from obscuring the compressor and ensuring stable compressor operation. This allows the air conditioner to adapt to the high-dust working environment of an electrolysis plant.
[0023] Preferably, the condenser is equipped with a second fan, and the condenser is fixedly connected to a second mesh cover that covers the second fan. The casing is provided with a second heat dissipation window located on the side of the condenser away from the second fan. A powder drop trough is provided between the condenser and the second heat dissipation window. A support frame is provided at the bottom of the condenser and is installed on the bottom wall of the casing.
[0024] This setup makes cleaning easier.
[0025] Preferably, the condenser is fixedly connected to a hanging plate, and the infusion pipe passes through the hanging plate.
[0026] This design improves the structural stability of the infusion tubing.
[0027] Compared with the prior art, this utility model has achieved beneficial technical effects:
[0028] 1. The elastic support blocks absorb the vibrations generated during compressor operation, effectively reducing the vibrations and noise transmitted to the driver's cab through the casing. Furthermore, the elastic deformation of the support legs allows them to adapt to compressor vibrations, further reducing vibrations transmitted from the base to the driver's cab, resulting in lower noise and vibration levels.
[0029] 2. When the compressor moves with the driver's cab, the elastic pads and support feet can absorb the impact, reduce the impact on the compressor, prevent the compressor from being damaged during the movement of the driver's cab, and play a role in protecting the compressor.
[0030] 3. Due to the dusty working environment of the overhead crane, dust easily accumulates at the bottom of the casing during long-term operation. If dust covers the compressor, it will seriously affect the compressor's heat dissipation. Elevating the compressor with elastic shims can prevent the compressor from being covered by dust at the bottom, ensuring that the compressor can operate stably and continuously in the electrolysis plant environment.

[0038] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.
[0039] refer to Figure 1-5 A novel multi-functional overhead crane operator's cab air conditioner includes an indoor unit 11 and an outdoor unit 12. The outdoor unit 12 includes a casing 21, a condenser 41, and a compressor 51. A liquid inlet pipe 22 is provided between the condenser 41 and the compressor 51. The casing 21 has a liquid return pipe 23 and an air inlet pipe 24. The liquid return pipe 23 is connected to both the condenser 41 and the indoor unit 11, and the air inlet pipe 24 is connected to both the indoor unit 11 and the compressor 51. The liquid return pipe 23 and the air inlet pipe 24 are wrapped with insulation material. The indoor unit 11 is installed inside the operator's cab, and the outdoor unit 12 is installed outside the operator's cab. Compressor 51 pressurizes the gaseous refrigerant, compressing it into a liquid state and delivering it to condenser 41. Condenser 41 dissipates the heat from the refrigerant into the air, cooling it down. The liquid refrigerant is then transported to indoor unit 11 via return pipe 23. Indoor unit 11 contains an evaporator. After entering the evaporator, the refrigerant is depressurized, returning to a gaseous state and absorbing heat from the air. Indoor unit 11 absorbs heat from the driver's cab, achieving the cooling function and lowering the air temperature inside the driver's cab. The refrigerant that has absorbed heat flows back to compressor 51 through intake pipe 24, completing the refrigerant circulation.
[0040] The compressor 51 is fixedly mounted on a base 52, and the base 52 is fixedly connected to multiple support legs 53. The support legs 53 extend horizontally away from the base 52, and their width gradually decreases away from the base 52. An elastic shim 54 is provided below each support leg 53. The two ends of the elastic shim 54 are respectively engaged with the support leg 53 and the bottom wall of the casing 21. Anchor bolts 55 are provided on the support legs 53, passing through the support legs 53, the elastic shim 54, and the bottom wall of the casing 21. Ribs 56 are fixedly connected to the support legs 53 and surround the elastic shim 54. The ribs 56 improve the structural stability of the support legs 53. The ribs 56 surrounding the elastic shim 54 prevent misalignment and facilitate accurate installation of the elastic shim 54.
[0041] The infusion tube 22 is equipped with a coil structure 61, which is located above the compressor 51. The infusion tube 22 at the coil structure 61 extends spirally upward away from the compressor 51. A support plate 62 is fixedly connected to the compressor 51, and a support frame 63 is mounted on the support plate 62. A buffer pad 64 is fixedly connected to the support frame 63, and the upper surface of the buffer pad 64 abuts against the coil structure 61. The buffer pad 64 provides support to the coil structure 61 from below, thus supporting the coil structure 61 and improving its stability. A clamping plate 65 is fixedly connected to the support frame 63, located inside the coil structure 61. A flexible pad 66 is fixedly connected to the clamping plate 65, which abuts against the coil structure 61. The flexible pad 66 blocks the inner side of the coil structure 61, preventing the coil structure 61 from misaligning with the buffer pad 64 in the horizontal direction, keeping the coil structure 61 in contact with the buffer pad 64, and further improving the stability of the coil structure 61. The support frame 63 has a vertically extending slot 67. A screw 68, threaded through the slot 67, is threaded onto the support plate 62. A washer 69, which engages with the support frame 63, passes through the screw 68. Moving the support frame 63 vertically allows the height of the buffer pad 64 to adapt to the height of the coil structure 61, ensuring effective support for the coil structure 61. When the support frame 63 moves vertically, the screw 68 can move relative to the support frame 63 within the slot 67. After the support frame 63 is adjusted to a suitable height, the screw 68 is tightened. The screw 68 presses against the support frame 63 through the washer 69, thus locking the support frame 63 onto the support plate 62.
[0042] A first mounting bracket 57 is fixedly connected to the casing 21, and a first fan 58 is mounted on the first mounting bracket 57 at the compressor 51. The first fan 58 drives air to flow towards the compressor 51, carrying away heat from the compressor 51 and ensuring stable operation. A partition 25 is fixedly installed on the casing 21, with the condenser 41 and compressor 51 located on opposite sides of the partition 25. The casing 21 has a first heat dissipation window 26 above the compressor 51. The partition 25 prevents heat generated by the compressor 51 from being transferred to the condenser 41, thereby improving the efficiency of heat dissipation and ensuring the cooling effect of the air conditioner. The partition 25 also blocks the air blown from the first fan 58 towards the compressor 51, guiding the air vertically to the first heat dissipation window 26 and exhausting it outside the casing 21, thus improving heat dissipation. The casing 21 is rotatably connected to a door 31. The door 31 has an air inlet 32 located at the first fan 58. A first mesh cover 33 is fixedly installed inside the air inlet 32 on the door 31. A dust removal groove 34 is provided between the lower end of the door 31 and the bottom wall of the casing 21. A door lock is provided between the door 31 and the casing 21. Rotating the door 31 toward the compressor 51 blocks the compressor 51, thereby reducing the noise generated by the compressor 51 and reducing the noise transmitted to the driver's cab.
[0043] A second fan 42 is installed on the condenser 41, and a second mesh cover 43 is fixedly connected to the condenser 41 to cover the second fan 42. The casing 21 has a second heat dissipation window 27 located on the side of the condenser 41 away from the second fan 42. A powder collection trough 44 is provided between the condenser 41 and the second heat dissipation window 27. A support frame 45 is provided at the bottom of the condenser 41 and is installed on the bottom wall of the casing 21. The second fan 42 drives air to flow sequentially through the condenser 41 and the second heat dissipation window 27, allowing the air to absorb heat from the condenser 41 and then be discharged outside the casing 21 through the second heat dissipation window 27, thus ensuring the heat dissipation effect of the condenser 41 and the cooling effect of the air conditioner. A mounting plate 46 is fixedly connected to the condenser 41, and a liquid delivery pipe 22 passes through the mounting plate 46. The mounting plate 46 supports the liquid delivery pipe 22, improving the structural stability of the liquid delivery pipe 22.
[0044] This embodiment has the following advantages:
[0045] The elastic shim 54 absorbs the vibration generated during the operation of the compressor 51, effectively reducing the vibration and noise transmitted to the driver's cab through the casing 21. Furthermore, the elastic deformation of the support leg 53 allows it to adapt to the vibration of the compressor 51, thereby effectively reducing the vibration transmitted from the base 52 to the driver's cab, achieving the advantage of lower noise and vibration transmitted to the driver's cab.
[0046] When the compressor 51 moves with the driver's cab, the elastic pad 54 and the support leg 53 can absorb the impact, reduce the impact on the compressor 51, prevent the compressor 51 from being damaged during the movement with the driver's cab, and play a role in protecting the compressor 51.
[0047] Because the overhead crane operates in a dusty environment, dust tends to accumulate at the bottom of the casing 21 during long-term operation. If this dust covers the compressor 51, it will severely affect the compressor's heat dissipation. By using the elastic shim 54 to elevate the compressor 51, the dust at the bottom can be prevented from covering the compressor 51, ensuring that the compressor 51 can operate stably and continuously in the electrolysis plant environment.
[0048] The air conditioner compressor 51 needs to move synchronously with the driver's cab. When the driver's cab moves, the compressor 51 will shake, which can easily cause deformation and wear at the interface between the compressor 51 and the pipeline, making it prone to damage. The coil structure 61 is designed so that it can elastically deform with the shaking of the compressor 51, preventing excessive pressure from the infusion pipe 22 on the interface of the compressor 51 when the compressor 51 shakes, thus protecting the pipeline.
[0049] A dust removal trough 34 is provided at the lower end of the door 31. Part of the airflow blown by the first fan 58 to the compressor 51 can be discharged outside the casing 21 through the dust removal trough 34. The air discharged from the dust removal trough 34 blows out the dust at the bottom of the casing 21. The compressor 51 is raised by the elastic shim 54, which reduces the resistance encountered by the dust when it is discharged from the dust removal trough 34, ensuring that the dust can be discharged through the dust removal trough 34. This effectively and permanently prevents the accumulation of dust under the compressor 51, preventing the dust accumulated at the bottom of the casing 21 from covering the compressor 51, ensuring the stable operation of the compressor 51, and enabling the air conditioner to adapt to the high dust working environment in the electrolysis plant.
[0050] When dust from the factory enters the condenser 41 with the air, the dust around the condenser 41 falls downwards to the bottom of the casing 21 due to gravity. The condenser 41 is then elevated using the shim 45, preventing dust accumulation at the bottom of the casing 21 from obscuring it and ensuring effective heat dissipation. Elevating the condenser 41 also increases the space at the bottom of the casing 21, making it easier to remove dust and facilitating cleaning.
[0051] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
