Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a clean-type electric-assisted mobile lifting and feeding machine. Background Technology

[0002] Elevator feeders are conveying equipment used in pharmaceutical manufacturing processes to transport materials.

[0003] Publication No. CN209872260U discloses a mobile rechargeable cleanroom elevator, including a mobile base, a lifting frame erected on the mobile base, a movable seat lifted and lowered inside the lifting frame, a first drive mechanism connected to the movable seat to drive its lifting and lowering, a rotating shaft rotatably mounted on the movable seat, a second drive mechanism connected to the rotating shaft to drive its rotation, a mounting base fixed on the rotating shaft, and a pair of clamping arms slidably mounted on the mounting base, with a third drive mechanism connected to the clamping arms to drive their sliding. This elevator's movement is achieved through a drive wheel and a driven wheel, which increases convenience during material transport. However, it has a drawback: the kinetic energy driving the rotation of the drive wheel comes from the user. Considering the weight of the material transferred into the hopper can reach several hundred kilograms, the labor intensity of manual transport is too high. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a clean electric-assisted mobile lifting and feeding machine to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This clean electric-assisted mobile lifting and feeding machine includes a movable frame, a lifting frame set above the frame, and a clamping seat that moves up and down on the lifting frame. The rear end of the frame is provided with two symmetrically distributed and brakeable rear casters, and the front end is provided with two symmetrically distributed front casters. The frame is also provided with a drive wheel assembly located between the two rear casters and driven by a motor. The drive wheel assembly is rotated on the ground by the kinetic energy provided by the motor, and can also match the rotation of the rear casters in the steering direction. The frame is also provided with a lithium battery for powering the motor and located on one side of the drive wheel assembly.

[0006] Further improvements include a drive wheel assembly comprising a connecting plate, a drive wheel, and an axle cover. The connecting plate is rotatably mounted on the frame and has a wheel frame assembled with the drive wheel via an axle. The motor is mounted on one of the outer side walls of the wheel frame and its drive shaft is assembled with the axle. The axle cover is mounted on the other outer side wall of the wheel frame and is axled to the axle.

[0007] Further improvements include a mounting plate on the frame for connecting the connecting plate, with a through mounting cavity formed within the mounting plate. A slewing bearing is installed in the mounting cavity to allow the drive wheel assembly to rotate in the steering direction. The inner ring of the slewing bearing is connected to the connecting plate by bolts, and the outer ring is connected to the fixing plate by bolts to confine the slewing bearing within the mounting cavity. The fixing plate is connected to the mounting plate by bolts.

[0008] Further improvements include the formation of an operating cavity within the fixing plate that is adapted to and penetrates the mounting cavity, with a cover plate installed inside the operating cavity.

[0009] Further improvements include an extension plate extending beyond the frame at one end of the connecting plate near the rear caster, with a control handle on the extension plate for controlling the rotation of the drive wheel assembly in the steering direction.

[0010] As a further improvement, a guide bar is also installed at the location on the frame where the front wheel is mounted.

[0011] The beneficial effects of this utility model are: This invention provides electric assistance through a lithium battery and a motor. The drive wheel assembly rotates after receiving electric assistance, so the user only needs to control the direction, greatly reducing the labor intensity. At the same time, the drive wheel assembly also has the same characteristics as the casters, that is, it can achieve 360-degree free rotation. Moreover, the drive wheel assembly and the two rear casters form a triangular configuration, so the steering linkage between the three is timely, making the steering response of the lifting feeder rapid.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings: Referring to the attached diagram: This clean-type electric-assisted mobile lifting and feeding machine includes a movable frame 1, a lifting frame 2 mounted above the frame 1, and a clamping seat 21 that moves up and down on the lifting frame 2. The rear end of the frame 1 is provided with two symmetrically distributed and brakeable rear casters 11, and the front end is provided with two symmetrically distributed front wheels 12. The frame 1 is also provided with a drive wheel assembly 4 located between the two rear casters 11 and driven by a motor 3. The drive wheel assembly 4 is rotated on the ground by the kinetic energy provided by the motor, and can also match the rotation of the rear casters 11 in the steering direction. The frame 1 is also provided with a lithium battery 5 for powering the motor 3 and located on one side of the drive wheel assembly 4. The principle of this invention is that the lithium battery 5 and the motor 3 provide electric assistance, and the drive wheel assembly 4 receives the electric assistance. That is, the rotation of the motor 3 synchronously drives the drive wheel assembly 4 to rotate. At this time, the drive wheel assembly 4 is the driving wheel, and the rear universal wheel 11 and the front rotating wheel 12 are the driven wheels and also rotate. In this way, the user only needs to control the direction, which greatly reduces the labor intensity. At the same time, the drive wheel assembly 4 also has the same characteristics as the universal wheel, that is, it can achieve 360-degree free rotation. Moreover, the drive wheel assembly 4 and the two rear universal wheels 11 form a triangular configuration, so the steering linkage response between the three is timely, making the steering response of the lifting feeder rapid. Meanwhile, the forward and reverse rotation of the motor 3 controls the forward and backward movement of the lifting feeder.

[0014] The drive wheel assembly 4 includes a connecting plate 41, a drive wheel 42, and an axle cover 43. The connecting plate 41 is rotatably mounted on the frame 1 and has a wheel frame 411 assembled with the drive wheel 42 via a shaft. The motor 3 is mounted on one outer wall of the wheel frame 411, and its drive shaft is assembled with the shaft. The axle cover 43 is mounted on the other outer wall of the wheel frame 411 and is shaft-connected to the shaft. The connecting plate 41 is mainly used for mounting the drive wheel 42 and for connecting to the frame 1. The wheel frame 411 for mounting the drive wheel 42 consists of two parts formed on the connecting plate. The side plate of 41 has a shaft between the two side plates. The shaft is connected to the drive wheel 42 by a key so that the drive wheel 42 does not rotate around the shaft. Instead, the shaft rotates on the side plate to drive the drive wheel 42. This arrangement is mainly because the shaft is connected to the drive shaft of the motor 3 by a coupling. The arrangement of the two side plates allows one side plate to be used to install the motor, and the other side plate to be used to install the shaft cover 43. The shaft cover 43 uses a ball bearing structure to increase the smoothness of the shaft rotation, which helps to ensure smoothness during load-bearing and transportation.

[0015] A mounting plate 6 is provided on the frame 1, and a through mounting cavity 61 is formed within the mounting plate 6. A slewing bearing 7, which allows the drive wheel assembly 4 to rotate in the steering direction, is disposed within the mounting cavity 61. The inner ring of the slewing bearing 7 is bolted to a connecting plate 41, and the outer ring is bolted to a fixing plate 8 to confine the slewing bearing 7 within the mounting cavity 61. The fixing plate 8 is bolted to the mounting plate 6. The mounting plate 6 itself can be fixed to the frame 1 by welding, and its mounting cavity 61 provides the final assembly position for the slewing bearing 7. The drive wheel assembly 4 is used to rotate in the steering direction. It can withstand large axial and radial loads and overturning moments at the same time, that is, it can ensure smooth steering even when under load. In this embodiment, the inner ring of the slewing bearing 7 is the rotating body and the outer ring is the fixed body. That is, the inner ring is connected to the connecting plate 41 by bolts, and the outer ring is connected to the fixing plate 8 by bolts. The fixing plate 8 is connected to the mounting plate 6 by bolts. This can ensure the installation stability of the slewing bearing 7 on the one hand, and the connection stability of the drive wheel assembly 4 and the slewing bearing 7 on the other hand.

[0016] The fixed plate 8 has an operating cavity 81 that is adapted to and penetrates the mounting cavity 61. The operating cavity 81 is covered with a cover plate 9. This arrangement allows the user to contact the slewing bearing 7 through the operating cavity 81, that is, to add lubricant to the slewing bearing 7 to increase the smoothness of the inner ring rotation. The cover plate 9 closes the operating cavity 81 when no lubricant is added, that is, to prevent material powder and other impurities from falling into the slewing bearing 7 through the operating cavity 81.

[0017] An extension plate 412 extending beyond the frame 1 is provided at one end of the connecting plate 41 near the rear caster 11. The extension plate 412 is equipped with a control handle 10 for controlling the rotation of the drive wheel assembly 4 in the steering direction. This arrangement allows the user to control the steering of the lifting feeder by controlling only the drive wheel assembly 4, as the rotating drive wheel 42 reduces steering difficulty by conforming to the steering method of a wheel, thus simplifying steering control. In this embodiment, the extension plate 412 is connected to the connecting plate 41 by welding. It has an L-shaped configuration with an obtuse angle; the inclined section is used for welding to the connecting plate 41, while the straight section is used to mount the control handle 10. This design is primarily to accommodate the position of the connecting plate 41.

[0018] Considering that when the user pushes the hopper support loaded with materials to the clamping seat 21, there is a gap between the support legs of the hopper support and the frame 1, which prevents the clamping seat 21 and the hopper support from achieving coaxiality immediately and requires adjustment, a guide bar 20 is also provided at the position of the front rotating wheel 12 on the frame 1. The guide bar 20 plays a role in quick positioning and its main function is to eliminate the gap between the support legs of the hopper support and the frame. Furthermore, when the hopper support moves to the clamping seat 21, the user can feel a significant squeezing sensation. In this way, no position adjustment is required, and the hopper support can achieve coaxiality with the clamping seat 21 when it reaches the clamping seat 21.

[0019] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
