Description

Technical Field

[0001] The utility model relates to the field of logistics and transportation, and in particular to a squeezer and pusher lifting device, equipment and system. Background Art

[0002] There are many liquid storage and transportation devices on the market for storage, transportation, filling and discharge of viscous liquids. The mainstream storage and transportation devices are: Intermediate Bulk Containers (IBC) and liners.

[0003] IBC generally includes: four side panels, top cover, base; liner generally includes: filling port, discharge port, liner body. There is a discharge port at the bottom of IBC, and the liner discharge port is connected and fixed to the IBC discharge port. When discharging, open the liner discharge port valve and start discharging. However, in the discharge of viscous liquid, the liquid is discharged slowly and the efficiency is low; after the discharge is completed, the liquid remains in the liner bag, resulting in cost waste. The existing squeezer includes a pair of squeezers and a driving device, wherein the pair of squeezers are configured to be able to operably clamp the clamped object between them, and while the pair of squeezers and the clamped object move relative to each other, the pair of squeezers apply a squeeze force to the clamped object, and the driving device is associated with the pair of squeezers and can at least drive one of the pair of squeezers to move relative to the other squeezer, so as to realize the efficient discharge of the viscous liquid in the liner from the liner. However, when the squeezer is used in conjunction with the IBC and the liner, the squeezer needs to be installed on the top of the IBC and the liner. Due to weight and other factors, manual handling will increase labor intensity and affect certain work efficiency. Utility Model Content

[0073] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0074] The first embodiment of the present invention relates to a squeezer and pusher lifting device 100. Figure 1 , Figure 2 , Figure 3 As shown, the pusher lifting system 400 includes: a container 410, a liner bag 420, a pusher lifting device 100 and a pusher 310. The pusher lifting device 100 is used to lift the pusher 310. The liner bag 420 is placed in the container 410. The top of the liner bag 420 has a filling port 421, and the bottom of the liner bag 420 has a discharge port 423. The pusher 310 has a pair of hinged clamping arms 311 and a power member 312. Each clamping arm 311 has a roller 3111 driven to rotate by the power member 312, and an outer cover 3112 for mounting the roller 3111. The pair of rollers 3111 cooperate to clamp the liner bag 420, and can reverse relative to each other to apply a pushing force to the liner bag 420.

[0075] like Figure 4 , Figure 5 As shown, the pusher lifting device 100 includes: a base 1, a support frame 2, a transmission assembly 3, a reel assembly 4 and a driving member 5. The support frame 2 is arranged on the base 1, and the transmission assembly 3 is arranged on the support frame 2. The reel assembly 4 includes: a reel 41 connected to the transmission assembly 3, and a lifting member 42 wound on the reel 41. The driving member 5 is used to drive the transmission assembly 3 to drive the reel 41 to reel or release the lifting member 42. The lifting member 42 is a pull rope 421 and a hook 422 arranged at the bottom of the stretching. The hook 422 hooks the pusher 310, and the reel 41 rolls up the pull rope 421. The lifting member 42 brings the pusher 310 up, so that the pusher 310 can be raised to the opening of the container 410, so that the pusher 310 can clamp the liner bag 420. In the embodiment, the lifting member 42 may not include a hook but can be directly bolted to the pusher 310. The support frame 2 extends to support above the container 410, and the driving member 5 drives the transmission component 3. The transmission component 3 allows the reel 41 to reel up the lifting member 42, and the lifting member 42 lifts the pusher 310. The reel 41 releases the lifting member 42, and the lifting member 42 puts down the pusher 310, so there is no need to manually lift the pusher, which makes it easy to install the pusher, improves work efficiency, and also meets the requirements in some environments where the pusher is too heavy to be installed manually.

[0076] The squeezer lifting device 100 has an unlocked state (eg Fig. 9 ) and self-locking state (such as Figure 8). When the pusher lifting device 100 is in the unlocked state, the lifting member 42 can be released from the reel 41 under the action of external force; when the pusher lifting device 100 is in the self-locking state, the driving member 5 drives the transmission assembly 3 to let the reel 41 reel up the lifting member 42. That is to say, in the unlocked state, the pusher 310 is only subject to gravity in the vertical direction and can fall freely. There is no connection between the driving member 5 and the pusher 310, and the operation of the driving member 5 will not cause any impact on the pusher 310. When the pusher 310 pushes the liner bag 420, the liquid level in the liner bag 420 gradually decreases with the pushing process. The pusher 310 has its own weight and has been located on the liner bag 420 to push the liquid, and the liquid level also drops. Understandably, in some embodiments, the pusher 310 may also be driven to descend by the driver, but when the pusher 310 pushes the liner bag 420, the driving member 5 in the pusher 310 drives the pusher 310 to descend, and the descending speed of the pusher 310 must match the descending speed of the liquid level, that is, the speed of the pusher 310 pushing the liquid in the liner bag 420. The self-locking state means that the driving member 5 is associated with the pusher 310, and the driving transmission assembly 3 allows the pusher 310 to be lifted or lowered to prevent the pusher 310 from falling suddenly.

[0077] Furthermore, if Figure 1 and Figure 3 As shown, the reel assembly 4 has a pair of lifting members 42, and the lifting members 42 of the pair of reel assemblies 4 are respectively used to connect the two ends extending along the length direction of the squeezer 310. Let the squeezer 310 pull more balanced. In some embodiments, the squeezer 310 can be connected to one lifting member 42 or more lifting members 42.

[0078] Furthermore, if Figure 5 As shown, the transmission assembly 3 includes: a transmission shaft 31 connected to the winding shaft 41, a transmission chain 32 connected to the transmission shaft 31, and a clutch 33 connected to the transmission chain 32. The driving member 5 is used to drive the clutch 33. When the clutch 33 rotates, it drives the transmission chain 32. When the transmission chain 32 drives, it drives the transmission shaft 31. When the transmission shaft 31 rotates, it drives the winding shaft 41 to rotate. Figure 8 As shown, the clutch 33 is rotatably connected to the support frame 2. When the clutch 33 rotates around the connection between the clutch 33 and the support frame 2 to the first position, the extruder lifting device 100 is in a self-locking state, and the clutch 33 is engaged with the driving member 5. Fig. 9 As shown, when the clutch 33 rotates around the connection between the clutch 33 and the support frame 2 to the second position, the extruder lifting device 100 is in an unlocked state, and the clutch 33 is separated from the driving member 5. The extruder lifting device 100 also includes: an indexing pin 6 connected to the clutch 33, and the indexing pin 6 is detachably connected to the support frame 2, and is used to position the clutch 33 in the first position or the second position.

[0079] Specifically, Figure 5 , Figure 6 , Figure 7 As shown, the clutch 33 has a main body 331, a clutch gear 332, a bearing 333, a main shaft 334, and a sprocket 335. The main shaft 334 connects the bearing 333, the clutch gear 332, and the sprocket to the main body 331. The rotating shaft 30 and the indexing pin 6 connect the main body 331 to the support frame 2. When the indexing pin 6 is removed, the main body 331 can be rotated around the rotating shaft to the first position or the second position. The driving member 5 has a driving gear 50. When the clutch 33 is in the first position, the clutch 33 is close to the driving member 5, and the clutch gear 332 is meshed with the driving gear 50. The driving member 5 can drive the clutch 33, so that the clutch 33 drives the transmission chain 32 to transmit, thereby driving the winding shaft 41 to rotate the winding lifting member 42. Remove the indexing pin 6 and allow the clutch 33 to rotate A° around the connection between it and the support frame 2 to the second position. Then use the indexing pin 6 to connect the clutch 33 to the support frame 2. At this time, the clutch 33 is in the second position, and the clutch 33 and the driving member 5 are separated from the clutch gear 332 and the driving gear 50. The driving member 5 cannot drive the clutch 33 and cannot allow the winding shaft 41 to be wound or the lifting member 42 to be released. In other words, the rise and fall of the pusher 310 is irrelevant to the driving member 5.

[0080] In addition, in other embodiments, Fig.12 and Fig.13 As shown, the pusher lifting device 500 may also be without the clutch 33, the driving member 5 includes a hand wheel 51 and a reducer 52, the transmission chain 32 is connected to the reducer 52, the hand wheel 51 drives the reducer, and then drives the transmission chain 32, so that the transmission chain 32 drives the transmission shaft 31 to realize the rotation of the winding shaft 41. In this embodiment, before the pusher 310 is started, as shown in FIG. Fig.12 As shown, the lifting member 42 is separated from the pusher 310. At this time, the driving member 5 is not associated with the pusher 310, that is, the pusher lifting device 100 is in the unlocked state, and the pusher 310 automatically sinks as the liquid in the liner bag 420 is discharged. In this process, the filling port fixing member 422 can be connected to the through port, and the stretching member 8 is connected to the horizontal extension part 21. When the pusher 310 descends with the liner bag 420, the stretching member 8 provides corresponding pulling force to the liner bag 420. After the discharge is completed, as shown in FIG. Fig.13 As shown, the lifting member 42 is connected to the pusher 310, and the driving member 5 is associated with the pusher 310, that is, the pusher lifting device 500 is in the self-locking state, and the lifting member 42 can lift the pusher 310. Therefore, in this embodiment, the unlocking state of the pusher lifting device 500 is that the lifting member 42 is separated from the pusher 310, and the self-locking state of the pusher lifting device 500 is that the lifting member 42 is connected to the pusher 310. In other words, by manually installing, the lifting member 42 is connected to the pusher 310 to achieve the unlocking state and the self-locking state.

[0081] In another embodiment, Fig.14 , Fig.15 , Fig.16 , Fig.17 As shown, the pusher lifting device 600 is not provided with a clutch 33, and the reel 41 is driven by a hand-cranked sprocket drive and a ratchet 72, and the pusher lifting device 600 has an unlocked state and a self-locked state. Specifically, in this embodiment, Fig.14 and Fig.17 As shown, the driving member 5 includes: a hand wheel 51, one end of the transmission chain 32 is connected to the support frame 2 through the main shaft 34 and the bearing 35, and the other end of the transmission chain 32 is connected to the transmission shaft through the second sprocket 37. The hand wheel 51 drives the main shaft 34 to drive the first sprocket 36 to drive the transmission chain 32, and the transmission chain 32 drives the second sprocket 37 to drive the transmission shaft 31 to rotate the winding shaft 41, so that the winding shaft 41 can reel in the lifting member 42. Fig.15 and Fig.16 As shown, the pusher lifting device 600 includes: a gear 72 fixed to the transmission shaft 31, a ratchet 72 hinged to the support frame 2, and the ratchet 72 is used to rotate to engage with the gear 71 or separate from the gear 71. When the ratchet 72 is engaged with the gear 71, the pusher lifting device 600 is in a self-locking state; when the ratchet 72 is separated from the gear 71, the pusher lifting device 600 is in an unlocking state. In use, if the unlocking state needs to be achieved, the ratchet 72 is manually moved to separate the ratchet 72 from the gear 71; if the unlocking state needs to be achieved, the ratchet 72 is manually moved to engage the gear 71.

[0082] Furthermore, if Fig.10 As shown, the support frame 2 includes: a horizontal extension portion 21 and a longitudinal extension portion 22 connected to the horizontal extension portion 21 , and the longitudinal extension portion 22 is connected to the base 1 .

[0083] In addition, if Figure 5 and 10 As shown, the transmission shaft 31 is horizontally extended and arranged on the horizontal extension portion 21, and the clutch 33 is movably connected to the longitudinal extension portion 22. Figure 5 , Figure 6 As shown, the longitudinal extension portion 22 is provided with a plurality of positioning holes 220, and at least one of the plurality of positioning holes 220 is used for the clutch 33 connected to the indexing pin 6 to be separated from the driving member 5 when the indexing pin 6 is inserted. At least one of the plurality of positioning holes 220 is used for the clutch 33 connected to the indexing pin 6 to be meshed with the driving member 5 when the indexing pin 6 is inserted. Two horizontally spaced positioning holes 220 may be provided as shown in the figure.

[0084] Furthermore, if Figure 4 , Fig.10As shown, the horizontal extension portion 21 is separated from the base 1 to form a placement area 13, and the longitudinal extension portion 22 is rotatably connected to the base 1. Fig.10 As shown, the longitudinal extension part 22 can be selected first, so that the horizontal extension part 21 is located above the container 410, and the lifting member 42 is lowered to connect with the squeezer 310, and the squeezer 310 is lifted, and then Figure 4 The longitudinal extension part 22 is rotated so that the horizontal extension part 21 and the pusher 310 are located above the container 410. At this time, the horizontal extension part 21 and the base 1 are separated to form a placement area 13. This makes it easier for the pusher lifting device 100 to install the pusher 310 without being disturbed by the container 410. Fig.11 As shown, the longitudinal extension portion 22 is connected to the base 1 via a rotating connector 9, and the rotating connector 9 is connected by at least a rotating shaft 91, a bearing 92, an axis fixing member 93, and an axis base 94.
