Description

Technical Field

[0001] This utility model relates to the field of process air conditioning maintenance technology, and in particular to a transport device. Background Technology

[0002] In cigarette production, process air conditioning is crucial for maintaining the temperature and humidity in the production workshop. Its large internal motors frequently malfunction and require replacement after long-term operation. However, because the motors weigh 200kg and need to be moved as a whole, it requires the combined efforts of at least five people. The air conditioning access door is too narrow for five people to pass through simultaneously, making multi-person transport impossible. Therefore, lacking specialized moving tools, the side panel near the air conditioner must be removed to allow for easier movement by five people. After the old motor is removed and the new air conditioning motor is installed, the side panel must be reinstalled. In other words, disassembling and installing the side panel becomes a necessary step in motor replacement, making the entire process cumbersome, time-consuming, labor-intensive, and posing serious safety hazards. Utility Model Content

[0003] The purpose of this invention is to solve the problems of cumbersome procedures, time-consuming and labor-intensive processes, and safety hazards associated with replacing air conditioner motors in existing technologies. This invention provides a transport device that allows the motor of a process air conditioner to be moved out without disassembling and installing the air conditioner side panel, simplifying the replacement process and effectively solving the problems of difficult and time-consuming motor transportation.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] Figure 1This diagram illustrates the structure of the transport device in an embodiment of the present invention. Figure 1 .like Figure 1 As shown, this utility model discloses a transport device, including: a mounting frame 1, a transport mechanism 2, a drive mechanism, and a transmission mechanism 4. The transport mechanism 2 is slidably mounted on the mounting frame 1 and is used to transport the air conditioner motor 5 to be replaced out of the inspection door and to transport the new air conditioner motor into the inspection door. The drive mechanism is mounted on the mounting frame 1 and is used to drive the transport mechanism 2 along a first direction (e.g., ...). Figure 1 (Sliding in the X direction). For example, in this embodiment, the drive mechanism is a motor 3. A transmission mechanism 4 is located between the drive mechanism and the carrying mechanism 2, and is connected to both the drive mechanism and the carrying mechanism 2. The transmission mechanism 4 is used to transmit power between the drive mechanism and the carrying mechanism 2. For example, the transmission mechanism 4 can be a sprocket and chain, or a gear and rack. Preferably, in this embodiment, the transmission mechanism 4 is a sprocket and chain.

[0048] When using the transport device provided in this application, firstly, one end of the transport device is inserted into the inspection door, while the other end is placed outside the inspection door and on the ground. Then, the drive mechanism and transmission mechanism 4 move the transport mechanism 2 along a first direction, bringing it closer to the air conditioner motor 5 to be replaced. Next, using the hoist (located inside the inspection door) provided with the process air conditioner, the air conditioner motor 5 is lifted and placed on the transport mechanism 2. The drive mechanism then moves the transport mechanism 2 in the opposite direction until the air conditioner motor 5 is outside the inspection door. Workers remove the air conditioner motor 5 from the transport mechanism 2 and place the new air conditioner motor on it. Finally, the drive mechanism moves the transport mechanism 2 along the first direction until it is inside the inspection door, and the hoist is used again to lift the new air conditioner motor from the transport mechanism 2 and place it in its installation position. This completes the motor replacement work.

[0049] By adopting the above technical solution and using a special transport device, the air conditioner motor 5 to be replaced can be moved out of the maintenance door without disassembling and installing the air conditioner side panel, and the new air conditioner motor can be transported to the inside of the maintenance door. This effectively solves the problems of cumbersome disassembly and assembly steps, difficult transportation, and long time consumption of air conditioner motors, reduces the labor intensity of operators, and reduces operational safety hazards.

[0050] Figure 2 This diagram illustrates the structure of the transport device in an embodiment of the present invention. Figure 2 .like Figure 2As shown, the transmission mechanism 4 includes a first sprocket 41, a second sprocket 42, and a chain 43. The first sprocket 41 is connected to the output end of the motor 3, the second sprocket 42 is rotatably connected to the mounting frame 1, and the chain 43 is sleeved on the first sprocket 41 and the second sprocket 42, meshing with them. The chain 43 is directly or indirectly connected to the transport mechanism 2.

[0051] Figure 3 Show Figure 2 A magnified view of part A in the middle. Figure 4 A partial structural diagram of the chain in an embodiment of this utility model is shown. For example... Figure 2 , Figure 3 and Figure 4 As shown, chain 43 is located below the carrying mechanism 2, and a slot 433 is provided on chain 43. The carrying mechanism 2 includes a placement plate 21 and a locking plate 22. Placement plate 21 is slidably mounted on mounting frame 1, and its upper surface is a bearing plane to facilitate the placement of the air conditioner motor 5 to be replaced. Locking plate 22 is located below placement plate 21, with its upper end connected to placement plate 21. The shape of the lower end of locking plate 22 matches the shape of slot 433, allowing the lower end of locking plate 22 to be inserted into slot 433. This enables the chain 43 to move along the first direction, driving placement plate 21 to move along the first direction, thereby carrying the air conditioner motor.

[0052] Figure 4 A partial structural diagram of the chain in an embodiment of this utility model is shown. For example... Figure 4 As shown, the chain 43 includes multiple links 431, each link 431 including links along the width direction of the chain 43 (e.g., ...). Figure 4 Two side plates 432 are spaced apart (as shown in the Y direction), and a slot 433 is the gap between the two side plates 432 (the width of the gap is as shown in the image). Figure 4 (As shown in dimension D1). Furthermore, the width of the lower end of the snap-fit ​​plate 22 is equal to the width of the slot 433, so that when the lower end of the snap-fit ​​plate 322 is inserted into the slot 433, the two can be securely connected. It should be noted that each link 431 also includes two pins 434, each pin 434 having its two ends rotatably connected to the side plate 432. When the chain 43 moves in the first direction, the pins 434 can apply a force to the snap-fit ​​plate 32, thereby causing the snap-fit ​​plate 22 to move in the first direction.

[0053] Optionally, such as Figure 2 As shown, along the second direction (i.e., the width direction of chain 43) on the mounting bracket 1, such as... Figure 2(As shown in the Y direction) A first guide rod 11 and a second guide rod 12 are provided at intervals, both extending along a first direction. A first roller 23 and a second roller 24 are rotatably connected to the bottom of the placement plate 21. The first roller 23 corresponds to the position of the first guide rod 11 and can roll on the first guide rod 11. The second roller 24 corresponds to the position of the second guide rod 12 and can roll on the second guide rod 12. By setting the first roller 23 and the second roller 24, the friction between the placement plate 21 and the first guide rod 11 and the second guide rod 12 can be reduced, thereby making the placement plate 21 run more smoothly.

[0054] Optionally, such as Figure 2 As shown, a first stop plate 25 is provided at the end of the first roller 23 opposite to the second roller 24, and the edge of the first stop plate 25 protrudes from the circumferential surface of the first roller 23. A second stop plate 26 is provided at the end of the second roller 24 opposite to the first roller 23, and the edge of the second stop plate 26 protrudes from the circumferential surface of the second roller 24. A first guide rod 11 and a second guide rod 12 are located between the first stop plate 25 and the second stop plate 26. When the transport mechanism 2 moves along the first direction, the first stop plate 25 and the second stop plate 26 can restrict the displacement of the transport mechanism 2 along the second direction, thereby making the transport mechanism 2 run more stably. For example, there are at least two first rollers 23 and two second rollers 24, with two first rollers 23 spaced apart above the first guide rod 11 along the first direction, and two second rollers 24 spaced apart above the second guide rod 12 along the first direction. In other words, the transport mechanism 2 is equipped with two rollers on both sides along the width direction, which can further reduce friction and make the transport mechanism 2 move more smoothly.

[0055] Optionally, such as Figure 1 As shown, the bottom of the mounting frame 1 is provided with a first leg assembly and a second leg assembly. The first leg assembly and the second leg assembly are respectively located at both ends of the mounting frame 1 along a first direction. The first leg assembly includes two first legs 13 spaced apart along a second direction, and the lengths of the two first legs 13 are adjustable. The second leg assembly includes two second legs 14 spaced apart along a second direction, and the lengths of the two second legs 14 are adjustable.

[0056] By adopting the above technical solution, the first leg 13 and the second leg 14 can be set up so that the transport device can stand on the ground. In addition, the lengths of the first leg 13 and the second leg 14 are adjustable to adapt to various usage environments.

[0057] Optionally, such as Figure 1 As shown, each first leg 13 includes a first sleeve 131 and a first adjusting rod 132. The first sleeve 131 extends along the vertical direction (e.g., ...). Figure 1Extending in the Z direction, the upper end of the first sleeve 131 is connected to the mounting bracket 1, and the inner wall of the first sleeve 131 is provided with internal threads. At least a portion of the first adjusting rod 132 is provided inside the first sleeve 131, and the first adjusting rod 132 is provided with external threads, and the first adjusting rod 132 is threadedly connected to the first sleeve 131. The length of the first support leg 13 is adjusted by adjusting the length of the first adjusting rod 132 inserted into the first sleeve 131.

[0058] Optionally, such as Figure 1 As shown, each second support leg 14 includes a second sleeve 141 and a second adjusting rod 142. The second sleeve 141 extends vertically, its upper end is connected to the mounting bracket 1, and its inner wall has internal threads. At least a portion of the second adjusting rod 142 is disposed within the second sleeve 141, and the second adjusting rod 142 has external threads, being threadedly connected to the second sleeve 141. The length of the second support leg 14 is adjusted by adjusting the length of the second adjusting rod 142 inserted into the second sleeve 141.

[0059] Optionally, such as Figure 1 As shown, the mounting frame 1 is also provided with a third leg assembly, which is located between the first leg assembly and the second leg assembly. The third leg assembly can slide relative to the mounting frame 1 along a first direction to change the relative position of the third leg assembly and the first leg assembly. The third leg assembly includes two third legs 15 spaced apart along a second direction, and the length of the two third legs 15 is adjustable.

[0060] Figure 5 This diagram shows a cross-sectional view of the third leg mounted on the mounting bracket in an embodiment of the present invention. Specifically, as shown... Figure 1 and Figure 5 As shown, each third support leg 15 includes a third sleeve 151 and a third adjusting rod 152. The third sleeve 151 extends vertically, and its upper end is slidably connected to the mounting bracket 1. The inner wall of the third sleeve 151 has internal threads. At least a portion of the third adjusting rod 152 is disposed within the third sleeve 151, and the third adjusting rod 152 has external threads, being threadedly connected to the third sleeve 151. The length of the third support leg 15 is adjusted by adjusting the length of the third adjusting rod 152 inserted into the third sleeve 151.

[0061] Optionally, such as Figure 5As shown, the mounting bracket 1 is provided with a sliding groove 16, which extends along a first direction. A slider 153 is provided at the upper end of the third sleeve 151, and the slider 153 can slide within the sliding groove 16. Specifically, in this embodiment, both the sliding groove 16 and the slider 153 have rectangular cross-sections, and there are two of each. The two sliding grooves 16 are located at the bottom of the first guide rod 11 and the second guide rod 12, respectively. Each sliding groove 16 contains one slider 153, thereby adjusting the position of the two third legs 15 along the first direction.

[0062] In practical use, since the mounting plane of the air conditioner motor is higher than the ground, the first leg 13 and the third leg 15 are generally adjusted to be of equal length and shorter than the length of the second leg 14, so that the first leg 13 and the third leg 15 extend into the inspection door and stand on the mounting plane of the air conditioner motor at the same time, while the second leg 14 is located outside the inspection door and stands on the ground.

[0063] When using the transport device provided in this application, firstly, one end of the transport device (i.e., the first leg 13 and the third leg 15) is inserted into the inspection door, while the other end of the transport device (i.e., the second leg 14) is located outside the inspection door and placed on the ground. Then, the drive mechanism and transmission mechanism 4 drive the transport mechanism 2 to move in the first direction, bringing the transport mechanism 2 closer to the air conditioner motor 5 to be replaced. Subsequently, using the hoist (located inside the inspection door) attached to the process air conditioner, the air conditioner motor 5 to be replaced is lifted and placed on the placement plate 21. The drive mechanism drives the transport mechanism 2 to move in the opposite direction until the air conditioner motor 5 to be replaced is moved outside the inspection door. Workers then remove the air conditioner motor 5 from the placement plate 21 and place a new air conditioner motor on the placement plate 21. Finally, the drive mechanism drives the transport mechanism 2 to move along the first direction until the placement plate 21 moves into the inspection door. Then, the hoist provided with the process air conditioner is used to lift the new air conditioner motor from the placement plate 21 and place it in the air conditioner motor installation position. This completes the replacement of the air conditioner motor.

[0064] The transport device provided in this application can move the air conditioner motor out of the maintenance door and transport the new air conditioner motor to the inside of the maintenance door without disassembling and installing the air conditioner side panel. This effectively solves the problems of cumbersome disassembly and assembly steps, difficult and time-consuming transportation of air conditioner motors, reduces the labor intensity of operators, and reduces operational safety hazards.

[0065] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
