Description

Technical Field

[0001] This disclosure relates to the field of air conditioning production technology, and in particular to a handling device and an air conditioning production system. Background Technology

[0002] Heavy objects are often required to be moved during industrial production and equipment installation.

[0003] Some related technologies use gantry cranes to lift heavy objects. However, the gantry crane is fixed in position and cannot be moved. The heavy object needs to be manually moved onto a forklift and then transferred to the gantry crane by the forklift. Manually moving heavy objects onto forklifts is not only labor-intensive and inefficient, but also poses safety hazards. Utility Model Content

[0004] In view of this, the present disclosure provides a handling device and an air conditioning production system that can assist in the handling of heavy objects.

[0005] In one aspect of this disclosure, a conveying device is provided, comprising:

[0006] The loading section has a load-bearing area;

[0007] The movable wheels are located at the bottom of the loading section;

[0008] The suspension unit is vertically positioned above the load-bearing area, forming a transport space between itself and the load-bearing area; and

[0009] A traction assembly is disposed on a suspension portion and configured to move relative to the suspension portion in a first direction. The traction assembly has a first drive member and a suspension member connected to the first drive member. The first drive member is configured to drive the suspension member to move vertically.

[0010] The suspension part extends beyond the bearing area in a first direction so that the hanging part can lift items outside the bearing area to the bearing area.

[0011] In some embodiments, the suspension portion includes a body region and an extension region connected to the body region, wherein the projection of the body region onto the horizontal plane is within the projection range of the bearing region, and the projection of the extension region onto the horizontal plane is outside the projection range of the bearing region.

[0012] The inner side of the suspension has a guide rail extending from the body area to the extension area along a first direction, and the traction component is movably disposed on the guide rail.

[0013] In some embodiments, the body region has hollowed-out weight-reduction holes.

[0014] In some embodiments, the width of the extended region on the side closer to the body region is greater than the width of the extended region on the side farther from the body region.

[0015] In some embodiments, the loading section further includes a mounting area disposed along a first direction on the side of the bearing area away from the traction component;

[0016] The conveying device also includes:

[0017] The grip section, located in the installation area, is used by operators to push and pull the device.

[0018] In some embodiments, the conveying device further includes:

[0019] A pressure sensing element, connected to the grip, is configured to acquire the pressure applied to the grip by the operator; and

[0020] The third drive unit, connected to the movable wheel, is configured to drive the movable wheel to rotate;

[0021] The output power of the third drive unit is configured to be adjusted according to the pressure value detected by the pressure sensor.

[0022] In some embodiments, the conveying device further includes:

[0023] The power unit, located in the mounting area and situated on the side closest to the load-bearing area relative to the grip, is configured to provide power to the electrical components of the conveying device.

[0024] In some embodiments, the conveying device further includes:

[0025] An obstacle detection unit is installed in the loading section and is configured to detect obstacles around the transport device.

[0026] In some embodiments, the conveying device further includes:

[0027] The display section, located adjacent to the grip section, is configured to display the working status of the conveying device.

[0028] In another aspect of this disclosure, an air conditioning production system is provided, comprising:

[0029] Any of the aforementioned transport devices is configured to transport an air conditioner inverter.

[0030] Therefore, according to the embodiments of this disclosure, by setting the suspension part to extend beyond the bearing area in the first direction, the hanging member can move both vertically and horizontally in the first direction to the outside of the bearing area. This allows the hanging member to move above the heavy object when the transport device approaches it. The horizontal and vertical movement of the hanging member moves the heavy object from outside the transport device to inside the transport device and unloads it from the transport device to outside the transport device, so that the heavy object can be transported to the target location by the transport device throughout the entire process. The process of the hanging member moving the heavy object into the loading area and transferring the heavy object from inside the transport device to outside the transport device does not require manual handling, which can reduce the labor and manual intervention required in the production and assembly process and help improve loading and unloading efficiency.

[0052] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0053] Some related technologies use gantry cranes to lift heavy objects. However, the gantry crane is fixed in position and cannot be moved. The heavy object needs to be manually moved onto a forklift and then transferred to the gantry crane by the forklift. Manually moving heavy objects onto forklifts is not only labor-intensive and inefficient, but also poses safety hazards.

[0054] In view of this, the present disclosure provides a handling device and an air conditioning production system that can assist in the handling of heavy objects.

[0055] Figure 1 This is a three-dimensional structural schematic diagram of some embodiments of the conveying device according to the present disclosure. Figure 2 These are schematic diagrams illustrating the structure of some embodiments of the conveying device according to this disclosure. Figure 3 These are schematic diagrams illustrating the structure of other embodiments of the conveying device according to this disclosure. Figure 4 This is a top view of some embodiments of the conveying device according to the present disclosure. Figures 1-4 In the diagram, the X direction is vertical, the first direction Y and the second direction Z are parallel to the horizontal direction, and the first direction Y is perpendicular to the second direction Z.

[0056] refer to Figures 1-4 The conveying device includes a loading section 1, moving wheels 2, a suspension section 3, and a traction assembly 4. The loading section 1 has a bearing area 11, and the moving wheels 2 are disposed at the bottom of the loading section 1.

[0057] The suspension part 3 is disposed above the bearing area 11 along the vertical direction X, forming a transport space between the suspension part 3 and the bearing area 11. The traction assembly 4 is disposed on the suspension part 3 and configured to move in the horizontal plane relative to the suspension part 3 along a first direction Y perpendicular to the vertical direction X. The traction assembly 4 has a first drive member 41 and a hanging member 42 connected to the first drive member 41. The first drive member 41 is configured to drive the hanging member 42 to move vertically.

[0058] The suspension part 3 extends beyond the bearing area 11 in the first direction Y so that the hanging part 42 can lift items outside the bearing area 11 to the bearing area 11.

[0059] Handling equipment is used to move heavy objects, including but not limited to components such as reactors, circuit breakers, transformers, converters, and copper busbars in air conditioners. These objects are relatively small in size but have a significant weight; for example, an air conditioner inverter is approximately 1 meter long, 0.5 to 5 meters wide, and 1 to 1.5 meters high, weighing 1 to 2 tons, with the internal reactor weighing 500 to 600 kilograms. Moving such heavy objects manually can easily lead to physical strain.

[0060] The loading section 1 can serve as the base plate of the transport device, used to support heavy objects during the movement of the transport device, and to provide installation space for electrical components and other equipment of the transport device. The bearing area 11 is the area in the loading section 1 used to place heavy objects.

[0061] The movable wheels 2 are located at the bottom of the loading section 1 and are used to move the conveying device relative to the working surface. The number of movable wheels 2 can be adjusted according to actual needs. For example, four movable wheels 2 can be provided, with each of the four movable wheels 2 located at one of the four vertices of the loading section 1.

[0062] Furthermore, the movable wheel 2 can be configured as a swivel wheel, which can rotate under the pushing and pulling force of the operator on the handling device, or it can be driven by a third drive device connected to the movable wheel 2.

[0063] The first drive component 41 of the traction assembly 4 includes a motor, a reducer, an actuator, a drum, a wire rope, and a pulley block, while the hanging component 42 includes a hook. The output torque of the motor is transmitted to the drum through the reducer, and the drum drives the wound wire rope to move, thereby raising or lowering the hanging component 42. The first drive component 41 can adjust the speed at which the hanging component 42 moves vertically.

[0064] The suspension part 3 can be the top plate of the conveying device, and the suspension part 3 and the loading part 1 are connected by a vertically arranged support part 9. The support part 9 includes, but is not limited to, plates or multiple columns spaced apart.

[0065] The suspension part 3 extends beyond the bearing area 11 along the first direction Y. After the loading part 1 approaches the heavy object, the area where the suspension part 3 extends beyond the bearing area 11 can be located above the heavy object. This allows the traction component 4 to directly suspend the heavy object outside the transport device by moving to a position that extends beyond the bearing area 11, and then horizontally move the heavy object along the first direction Y to the bearing area 11. This realizes the process of transporting the heavy object from outside the transport device to inside the transport device, eliminating the need for manual handling. When the transport device reaches the target position, the traction component 4 is moved outside the bearing area 11, allowing the heavy object to be unloaded outside the transport device.

[0066] In this embodiment, by setting the suspension part 3 to extend beyond the bearing area 11 along the first direction Y, the hanging part 42 can move both vertically and horizontally along the first direction Y to the outside of the bearing area 11. Thus, when the transport device approaches the heavy object, the hanging part 42 moves above the heavy object. Through the horizontal and vertical movement of the hanging part 42, the heavy object is moved from outside the transport device to inside the transport device and unloaded from the transport device to outside the transport device, so that the heavy object can be transported to the target location by the transport device throughout the entire process. The process of the hanging part 42 moving the heavy object into the loading area 11 and moving the heavy object from inside the transport device to outside the transport device does not require manual handling, which can reduce the labor and manual intervention required in the production and assembly process and help improve loading and unloading efficiency.

[0067] refer to Figures 1-3 In some embodiments, the suspension part 3 includes a main body region 31 and an extension region 32 connected to the main body region 31. The projection of the main body region 31 on the horizontal plane is within the projection range of the bearing region 11, and the projection of the extension region 32 on the horizontal plane is outside the projection range of the bearing region 11. The inner side of the suspension part 3 has a guide rail extending from the main body region 31 to the extension region 32 along the first direction Y, and the traction component 4 is movably disposed on the guide rail.

[0068] The main body region 31 is located directly above and opposite the loading region 11, and the support portion 9 is connected to the edge of the main body region 31 and the edge of the loading region 11 respectively. The inner side of the suspension portion 3 refers to the side of the main body region 31 and the extension region 32 facing the loading region 11 in the vertical direction X.

[0069] The guide rail extends from the main body region 31 to the extension region 32 along the first direction Y, thereby enabling the hanging component 42 to move along the guide rail to the extension region 32, realizing the loading and unloading of heavy objects between the inside and outside of the handling device.

[0070] Specifically, the conveying device may further include a movable member and a second driving member. The movable member is movably connected to the guide rail and connected to the traction assembly 4. The second driving member is drivenly connected to the movable member and configured to cause the movable member to drive the traction assembly 4 to move horizontally along the guide rail. The second driving member can adjust the moving speed of the movable member along the first direction Y.

[0071] The movable component can be fixedly connected to the traction assembly 4. Driven by the second drive component, the movable component carries the traction assembly 4 horizontally along the track, realizing the reciprocating movement of the hanging component 42 between the main body area 31 and the extension area 32. The movable component can improve the stability of the horizontal movement of the hanging component 4 and reduce swaying.

[0072] In this embodiment, by providing a guide rail extending from the main body region 31 to the extension region 32 along the first direction Y on the inner side of the suspension part 3, and moving the traction component 4 along the first direction Y of the guide rail, the hanging part 4 can achieve more precise and stable operation in the horizontal direction, thereby helping to realize the process of moving heavy objects from outside the handling device to inside the handling device and unloading them from the handling device to outside the handling device more efficiently and reliably.

[0073] refer to Figure 1 and Figure 3 In some embodiments, the body region 31 has a hollowed-out weight-reduction hole 311. The weight-reduction hole 311 extends through the body region 31 in the vertical direction X, and the weight-reduction hole 311 and the guide rail are spaced apart in the horizontal direction to prevent interference.

[0074] The shape of the weight-reducing hole 311 can be adjusted according to the shape of the body area 31, for example, it can be set to a rectangle. The number of weight-reducing holes 311 can be adjusted according to the actual situation, for example, two weight-reducing holes 311 can be set.

[0075] In this embodiment, by providing a hollowed-out weight-reducing hole 311 in the body area 31, the weight of the suspension part 3 can be reduced, thereby reducing the weight of the handling device. This facilitates reducing the drive load of the handling device, reducing drive energy consumption, or making it easier for operators to push and pull manually. It also improves the flexibility of the handling device during movement. The weight-reducing hole 311 also helps to lower the center of gravity of the handling device, making the handling device run more stably during transportation.

[0076] refer to Figure 1 and Figure 3 In some embodiments, the width of the extension region 32 on the side closer to the main body region 31 is greater than the width of the extension region 32 on the side farther from the main body region 31, and the specific shape of the extension region 32 can be adjusted according to the actual situation.

[0077] The extension region 32 can be set on one side of the main body region 31 along the first direction Y. The extension region 32 is set in a shape that gradually narrows along the first direction Y. This can not only meet the connection strength between the extension region 32 and the main body region 31 and ensure the stability of the hanging part 4 when suspending heavy objects at the extension region 32, but also further reduce the weight of the suspension part 3.

[0078] In this embodiment, by setting the width of the extension area 32 on the side closer to the main body area 31 to be greater than the width of the extension area 32 on the side farther from the main body area 31, under the premise of satisfying the connection strength between the extension area 32 and the main body area 31 and ensuring the reliability of the hanging part 4 in suspending heavy objects, the risk of interference between the extension area 32 and the objects around the heavy objects when the handling device is close to the heavy objects can be reduced, and the loading and unloading of heavy objects can be carried out more safely and efficiently. It also helps to further reduce the weight of the suspension part 3, lower the center of gravity of the handling device, and make the handling device run more stably during transportation.

[0079] refer to Figure 1 and Figure 2 In some embodiments, the loading section 1 further includes a mounting area 12, which is disposed along a first direction Y on the side of the bearing section 11 away from the traction component 4. The transport device also includes a gripping section 5, which is disposed in the mounting area 12 and is used by the operator to push and pull the transport device. The gripping section 5 includes a handle that facilitates the operator's gripping and pushing and pulling of the transport device. The structural form of the gripping section 5 can be adjusted according to actual needs and the spatial layout of the transport device to make it easier and less strenuous for the operator to grip it.

[0080] In this embodiment, a gripping part 5 is provided on the side away from the heavy object bearing area 11, which makes it easier for the operator to act on the handling device to drive the movement of the handling device. The operator is located on the side away from the heavy object, which can prevent the heavy object from tipping over or slipping and injuring the operator during transportation. It can also provide the operator with a longer lever arm, so that the operator can save effort and improve the efficiency of heavy object handling.

[0081] In some embodiments, the conveying device further includes a pressure sensing element and a third drive element. The pressure sensing element is connected to the grip 5 and configured to acquire the pressure applied to the grip 5 by an operator.

[0082] The third drive unit is connected to the movable wheel 2 and is configured to drive the movable wheel 2 to rotate. The output power of the third drive unit is adjustable and is configured to adjust according to the pressure value applied by the operator detected by the pressure detection element.

[0083] The pressure detection element includes a pressure sensor, which can be disposed on the grip 5 to obtain the magnitude of the pulling or pushing force applied by the operator to the grip 5.

[0084] Some material handling equipment in related technologies lacks a flexible control mechanism, resulting in uneven start-up and braking processes that affect operational safety and operator experience. By adjusting the output power of the third drive component in real time according to the pressure applied by the operator, the start-up and braking processes of the material handling device can be made smoother, thereby improving operational safety and operator experience.

[0085] In this embodiment, the output power of the third drive unit can be adjusted according to the magnitude of the pressure or thrust obtained by the pressure detection device and the weight of the load. This allows the third drive unit to provide corresponding assistance to the operator for different carrying conditions, enabling the handling device to achieve flexible start-up and rapid braking, and to provide flexible and stable assistance during the movement of the handling device. This avoids the safety hazards caused by sudden start-up or sudden stop of the handling device, thereby improving the safety and operability of the handling device.

[0086] refer to Figures 1-4 In some embodiments, the conveying device further includes a power assembly 6 disposed in the mounting area 12 and located on the side near the bearing area 11 relative to the gripping portion 5, configured to provide power to the electrical components of the conveying device. The electrical components of the conveying device include, but are not limited to, a first drive member 41, a second drive member, a third drive member, a pressure detection member, an obstacle detection member, and a display unit 8.

[0087] The power assembly 6 includes one or more battery modules 61, which are detachably mounted in the mounting area 12 for easy replacement. The power assembly 6 can also be powered by solar charging to enhance the device's range in outdoor or power-constrained environments.

[0088] The power unit 6 can also be charged via fast charging, giving the handling device good endurance and enabling it to adapt to various working environments and achieve long-term continuous operation.

[0089] In this embodiment, the handling device is equipped with a power component 6 to achieve flexible endurance. The power component 6 is set on one side of the bearing area 11. The weight of the power component 6 can be used as a counterweight for the handling device to achieve torque balance with the heavy object being handled, so as to improve the anti-overturning stability of the handling device, which is beneficial to protecting the safety of the operator, helping to reduce the drive requirements, and optimizing the energy consumption of the handling device.

[0090] In some embodiments, the conveying device further includes an obstacle detection element disposed on the loading section 1 and configured to detect obstacles around the conveying device. The obstacle detection element may include ultrasonic sensors or radar to monitor obstacles, thereby improving the safety protection capability of the conveying device during movement and reducing accidents such as expansion.

[0091] In this embodiment, by setting up obstacle detection devices to detect obstacles in the transport device in real time, operators can be assisted in determining whether there are obstacles in the surrounding environment that affect passage, so as to prevent the transport device from colliding with surrounding obstacles and help improve the safe passage capability of the transport device.

[0092] In some embodiments, the conveying device further includes a display unit 7, which is disposed adjacent to the gripping unit 5 and configured to display the operating status of the conveying device. The operating status of the conveying device includes, but is not limited to, the electrical status of the power component 6, the operating speed of the traction component 4, and the detection results of the pressure detection element and the obstacle detection element.

[0093] Operators can charge or swap batteries promptly when low battery is displayed to ensure battery life, and brake in time when surrounding obstacles are detected. The display unit 7 can also be controlled by voice to reduce the need for operators' hands and improve ease of use.

[0094] Furthermore, the display unit 7 can also integrate the control of the first drive member 41, the second drive member and the third drive member, so that the operator can adjust the running speed of the traction assembly 4, the start and stop of the conveying device and the output torque of the first drive member 41, the second drive member and the third drive member through the display unit 7, so as to improve the operability of the conveying device.

[0095] In this embodiment, the display unit 7 provides the operator with the working status information of the conveying device, so that the operator can monitor and adjust the operation of the conveying device in real time, thereby enabling the conveying device to achieve efficient and reliable conveying under different working conditions.

[0096] In another aspect of this disclosure, an air conditioning production system is provided, including a transport device as described in any of the above embodiments, the transport device being configured to transport an air conditioner inverter. The transport device can transport the inverter and components such as the inverter's reactor, circuit breaker, and / or transformer.

[0097] In this embodiment, the air conditioning production system uses a handling device to transport heavy objects such as the frequency converter inside the air conditioner, which can eliminate the need for manual handling of heavy objects, reduce the labor and human intervention required in the production and assembly process, and help improve loading and unloading efficiency.

[0098] In some embodiments, the traction component 4 may also take the form of a telescopic robotic arm that can extend outside the handling device to load and unload heavy objects at different heights and in different spaces.

[0099] refer to Figures 1-4 The following are the operation procedures of the conveying device in some embodiments:

[0100] After the conveying device is powered on, it checks whether the entire machine can operate normally and uses obstacle detection devices to detect the distance to surrounding obstacles. If it is determined that the machine can pass through, the high-voltage circuit is activated, and the motor enters a locked state. If the surrounding obstacles are too close, a voice announcement will be made to allow the operator to move the obstacles away.

[0101] The system checks whether there are goods in the carrying area 11. If there are no goods, the operator selects whether to run the machine empty. When the handling device is determined to run, the drive motor is unlocked, and the device enters the pre-running state. The system checks whether there is pulling or pushing force in the gripping part 5, and the drive motor outputs power proportionally to the magnitude of the pulling or pushing force.

[0102] The operator can press the stop button to lock the drive motor and unlock the lifting motor. The operator then uses the remote control handle or display screen to operate the lifting motor to complete the loading and unloading of goods.

[0103] When the conveying device malfunctions, the fault indicator light will illuminate, and the display screen will show the fault information. After troubleshooting, the operator can click the restart button. The operator can also shut down the conveying device using the power off button. The conveying device will also automatically shut down if there is no operation for five minutes while in standby mode.

[0104] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
