Description

Technical Field

[0001] This application relates to the field of cigarette manufacturing equipment, and more specifically, to a fabric cart lifting device. Background Technology

[0002] In the maintenance of tobacco production equipment, especially during the repair of the feeding cart in the leaf storage cabinet or tobacco storage cabinet, when operations such as wheel replacement, axle replacement, or bearing replacement require lifting the feeding cart, the conventional operating procedure is to use rectangular wooden blocks as support tools to lift the equipment. After the equipment is lifted to an appropriate height, additional wooden blocks need to be placed near the axles to maintain the equipment's suspended state, thus creating conditions for subsequent maintenance work.

[0003] This traditional method of lifting fabric carts has obvious limitations: on the one hand, the operation process is relatively complicated, which significantly prolongs the maintenance time; on the other hand, the operation method lacks standardized safety protection measures and poses potential safety risks.

[0004] The purpose of this application is to provide a fabric cart lifting device that can lift the fabric cart for easy maintenance.

[0005] This utility model provides a fabric cart lifting device, which includes a support, a lifting component, a connecting component, and two sets of traveling components. The lifting component is installed on the support, and the connecting component is installed at the end of the lifting component away from the support. The two sets of traveling components are respectively arranged on both sides of the support along a first direction, and each set of traveling components is provided with a traveling end that can be raised and lowered.

[0006] In an optional embodiment, each set of walking components includes a mounting bracket, a connecting bracket, a first connecting shaft, a second connecting shaft, a telescopic member, a linkage mechanism, and a roller. The two mounting brackets are spaced apart along a second direction perpendicular to the first direction. The connecting bracket is disposed between the two mounting brackets. The first connecting shaft extends along the second direction to the two mounting brackets. The second connecting shaft extends along the second direction to the two mounting brackets. The second connecting shaft is located on the side of the first connecting shaft closer to the connecting bracket. One end of the telescopic member is rotatably connected to the first connecting shaft, and the other end of the telescopic member is rotatably connected to the linkage mechanism. The linkage mechanism is rotatably connected to the second connecting shaft and the connecting bracket, respectively. The roller is mounted on the output end of the linkage mechanism and is the walking end. Under the action of the telescopic member, the roller descends to a first position.

[0007] In an optional embodiment, the linkage mechanism includes a first link, a second link, and a third link. One end of the first link is rotatably connected to the second connecting shaft. One end of the second link is rotatably connected to the end of the first link away from the second connecting shaft. The other end of the second link is rotatably connected to the third link. One end of the third link is rotatably connected to the connecting bracket. The other end of the third link is equipped with a roller.

[0008] In an optional embodiment, the third link includes a first connecting part and a second connecting part, the first connecting part being rotatably connected to the connecting bracket, the second connecting part being set at an angle to the first connecting part, the angle being directed toward the connecting bracket, and the roller being mounted on the end of the second connecting part away from the first connecting part.

[0009] In an optional embodiment, the linkage mechanism further includes a sleeve disposed on the second linkage.

[0010] In an optional embodiment, the fabric cart lifting device further includes a fixing member and a moving member. The fixing member is fixed to the bottom of the support, and the moving member is spaced apart from the fixing member and defines a sliding groove. The moving member is moved to adjust the width of the sliding groove.

[0011] In an optional embodiment, a sliding mechanism is provided between the moving member and the support, wherein the sliding seat of the sliding mechanism is disposed on one of the moving member and the support, and the guide rail of the sliding mechanism is disposed on the other of the moving member and the support.

[0012] In an optional implementation, when the sliding element is in place, it is connected to the support by bolts.

[0013] In an optional embodiment, the fabric carriage lifting device further includes a buffer element that passes through the movable element and extends to the fixed element.

[0014] In an optional embodiment, the fabric cart lifting device further includes a pushing member, which is fixedly connected to the support.

[0015] Compared to existing technologies, the beneficial effects of this application are:

[0016] This application moves the fabric carriage lifting device to the lifting position using a walking component, and then uses a lifting component to lift the fabric carriage, which facilitates maintenance work. In addition, the walking end of this application can be raised and lowered.

[0033] Example 1

[0034] Please see Figure 1 and Figure 2 This embodiment is applicable to the lifting of the fabric carriage 20. The fabric carriage 20 travels on the track 31 of the cabinet 30 via wheels 21. During normal production, the wheels 21 are in contact with the track 31. When maintenance is required, the fabric carriage 20 needs to be lifted until the wheels 21 leave the track 31.

[0035] Please see Figure 3 This embodiment provides a fabric cart lifting device 10, which includes a support 100, a lifting component 200, a connecting component 300, and two sets of walking components 400.

[0036] The support 100 is a flat plate structure, and the support 100 has an upper surface and a lower surface.

[0037] Please see Figure 3 and Figure 4 The lifting component 200 is installed on the support 100. Specifically, the lifting component 200 is located on the upper surface of the support 100, and the lifting component 200 includes a first fixing part 210, a second fixing part 220 and a lifting part 230. The first fixing part 210 is fixedly connected to the support 100, and the lifting part 230 is supported between the first fixing part 210 and the second fixing part 220.

[0038] The first fixing part 210 is provided with a strip hole 211 to facilitate adjustment of the installation position.

[0039] It should be understood that the lifting part 230 has a lifting function and can be a component with a lifting function such as a cylinder or hydraulic cylinder. In this embodiment, the lifting part 230 can be configured to include a body 231 and a piston rod 232, with the piston rod 232 extending or retracting relative to the body 231.

[0040] Please see Figures 3 to 5 The connector 300 is installed at the end of the lifting member 200 away from the support 100. The connector 300 is fixedly connected to the second fixing part 220. Specifically, the connector 300 is provided with a first connecting hole 310 and a second connecting hole 320. The first connecting hole 310 extends in the vertical direction and the second connecting hole 320 extends in the horizontal direction.

[0041] The fastener passes through the first connecting hole 310 and is threadedly connected to the second fixing part 220 below. In this embodiment, after the fastener passes through the first connecting hole 310 and the strip hole 211, it is locked by a nut. The nut is located on the side of the second fixing part 220 close to the first fixing part 210.

[0042] Due to the design of the strip hole 211, the connector 300 can move back and forth relative to the lifting member 200.

[0043] Please see Figure 1 and Figure 5 The fastener passes through the second connecting hole 320 and is threadedly connected to the fabric carriage 20. Specifically, the fabric carriage 20 is provided with a mounting hole 22 corresponding to the second connecting hole 320. The mounting hole 22 is provided with an internal thread, which matches the external thread of the fastener.

[0044] To improve the stability of the fabric cart lifting device 10, multiple first connecting holes 310 and multiple second connecting holes 320 are provided. The number of mounting holes 22 is consistent with the number of second connecting holes 320 and they correspond one-to-one.

[0045] To improve the reliability of the connector 300, this embodiment provides a reinforcing rib 330 on the connector 300.

[0046] Please see Figure 1 , Figure 3 and Figure 6 Two sets of walking components 400 are respectively arranged on both sides of the support 100 along the first direction, and each set of walking components 400 is provided with a walking end that can be raised and lowered. The first direction is the extension direction of the track 31.

[0047] Each walking assembly 400 includes a mounting bracket 410, a connecting bracket 420, a first connecting shaft 430, a second connecting shaft 440, a telescopic member 450, a linkage mechanism 460, and a roller 470. The two mounting brackets 410 are spaced apart along a second direction perpendicular to the first direction. The connecting bracket 420 is located between the two mounting brackets 410. The first connecting shaft 430 extends along the second direction to the two mounting brackets 410, and the second connecting shaft 440 extends along the second direction to the two mounting brackets 410. The second connecting shaft 440 is located on the side of the first connecting shaft 430 closer to the connecting bracket 420. One end of the telescopic member 450 is rotatably connected to the first connecting shaft 430, and the other end of the telescopic member 450 is rotatably connected to the linkage mechanism 460. The linkage mechanism 460 is rotatably connected to the second connecting shaft 440 and the connecting bracket 420, respectively. The roller 470 is mounted on the output end of the linkage mechanism 460 and is the walking end. Under the action of the telescopic member 450, the roller 470 descends to the first position.

[0048] When roller 470 descends to the first position, roller 470 abuts against track 31. When roller rises to the second position, roller 470 disengages from track 31.

[0049] The linkage mechanism 460 includes a first link 461, a second link 462, and a third link 463. One end of the first link 461 is rotatably connected to the second connecting shaft 440. One end of the second link 462 is rotatably connected to the end of the first link 461 away from the second connecting shaft 440. The other end of the second link 462 is rotatably connected to the third link 463. One end of the third link 463 is rotatably connected to the connecting bracket 420. The other end of the third link 463 is equipped with a roller 470.

[0050] Please see Figure 6 and Figure 7 The third link 463 includes a first connecting part 4631 and a second connecting part 4632. The first connecting part 4631 is rotatably connected to the connecting bracket 420. The second connecting part 4632 is set at an angle to the first connecting part 4631, with the angle facing the connecting bracket 420. A roller 470 is installed at the end of the second connecting part 4632 away from the first connecting part 4631.

[0051] Please see Figure 1 , Figure 3 and Figure 6 Based on the above, this embodiment further explains the operating principle of the fabric cart lifting device 10 as follows:

[0052] S100. Place the fabric cart lifting device 10 on the track 31 and apply force to the linkage mechanism 460, causing the roller 470 to press down.

[0053] It should be understood that while the roller 470 is pressing down, the support 100, the lifting component 200, the connecting component 300, and other components of the traveling assembly 400 are moving upward relative to the roller 470.

[0054] S200. Under the action of the telescopic member 450, the roller 470 remains in contact with the track 31.

[0055] Please see Figure 1 and Figure 5 .

[0056] S300. Push the fabric cart lifting device 10 until the second connecting hole 320 is aligned with the mounting hole 22 in the vertical direction.

[0057] In this embodiment, the fabric cart lifting device 10 can be set to the lifting position.

[0058] Please continue reading. Figure 1 , Figure 3 and Figure 6 .

[0059] S400. Apply a reverse force to the linkage mechanism 460, causing the roller 470 to rise and retract.

[0060] Correspondingly, as the roller 470 rises, the support 100, the lifting component 200, the connecting component 300, and other components of the traveling assembly 400 descend relative to the roller 470.

[0061] Please see Figure 2 , Figure 3 and Figure 5 .

[0062] S500. Control the lifting component 200 to rise, which in turn drives the connecting component 300 to rise until the second connecting hole 320 and the mounting hole 22 are aligned in the horizontal direction.

[0063] S600. The fabric carriage lifting device 10 and the fabric carriage 20 are locked together by fasteners.

[0064] Please see Figure 2 and Figure 3 Before locking the fabric cart lifting device 10, adjust the position of the connector 300 so that the connector 300 fits against the wall panel of the fabric cart 20. This will improve the connection reliability after locking the fabric cart lifting device 10.

[0065] S700. Control the lifting component 200 to continue rising until the wheel 21 leaves the track 31 at the preset height.

[0066] S800. After maintenance is completed, control the lifting component 200 to descend until the wheel 21 touches the rail 31, and remove the fabric cart lifting device 10.

[0067] In this embodiment, the fabric carriage lifting device 10 is moved to the lifting position by the walking component 400, and then the lifting component 200 is used to lift the fabric carriage 20, which facilitates maintenance work. In addition, the walking end of this embodiment can be raised and lowered. When the walking end is lowered, the fabric carriage lifting device 10 moves. When the walking end is raised, the fabric carriage lifting device 10 is lifted.

[0068] Example 2

[0069] Please see Figure 6 Based on Embodiment 1, this embodiment is improved in that the linkage mechanism 460 further includes a sleeve 480, which is disposed on the second link 462.

[0070] In this embodiment, a rod (not shown in the figure) is inserted into the sleeve 480. The sleeve 480 overcomes the resistance of the telescopic member 450. Lifting the rod upward achieves the purpose of applying force to the linkage mechanism 460, and pressing the rod downward achieves the purpose of applying force to the linkage mechanism 460 in the opposite direction. This embodiment uses the rod as a force-applying element, which reduces the difficulty of applying force.

[0071] Example 3

[0072] Please see Figure 8 Based on the above embodiments, this embodiment is improved in that the fabric cart lifting device 10 further includes a fixing member 500 and a moving member 600. The fixing member 500 is fixed to the bottom of the support 100, and the moving member 600 is spaced apart from the fixing member 500 and defines a sliding groove. The moving member 600 is moved to adjust the width of the sliding groove.

[0073] A sliding mechanism 700 is provided between the movable component 600 and the support 100. The sliding seat 710 of the sliding mechanism 700 is disposed on one of the movable component 600 and the support 100, and the guide rail 720 of the sliding mechanism 700 is disposed on the other of the movable component 600 and the support 100. When the sliding mechanism 700 is in place, the movable component 600 and the support 100 are connected by bolts 730.

[0074] Please see Figure 1 and Figure 8 Before placing the fabric cart lifting device 10, adjust the width of the sliding groove to be wider than the width of the track 31 to facilitate the movement of the fabric cart lifting device 10. When the fabric cart lifting device 10 is moved to the lifting position, adjust the width of the sliding groove so that the groove wall contacts the side of the track 31 to ensure that the fabric cart lifting device 10 will not shake or become unstable during the subsequent lifting process.

[0075] This embodiment adapts to different widths of track 31 by adjusting the width of the sliding groove, which has good adaptability and can be adapted to various specifications of track 31, providing good flexibility.

[0076] Example 4

[0077] Please see Figure 2 , Figure 6 and Figure 8 Based on the above embodiments, this embodiment is improved in that the fabric cart lifting device 10 further includes a buffer 800, which passes through the movable member 600 and extends to the fixed member 500. The buffer 800 is tightened by adjusting the bolts 730 on the movable member 600.

[0078] In this embodiment, when the third link 463 touches the buffer 800, the roller 470 is pressed down to the first position. When the roller 470 rises and retracts, the lower surface of the buffer 800 abuts against the track 31, providing buffering force for the descent of the fabric cart lifting device 10 and preventing the fabric cart lifting device 10 from colliding and being damaged by the track 31.

[0079] Example 5

[0080] Please see Figure 2 Based on the above embodiments, this embodiment is improved in that the fabric cart lifting device 10 further includes a pusher 900, which is fixedly connected to the support 100.

[0081] The pusher 900 serves as the point of application for the pushing force of the fabric cart lifting device 10, which can reduce the difficulty of pushing and improve the pushing efficiency.
