Description

Technical Field

[0001] The present invention relates to a mechanical device, in particular to a lifting device. Background Art

[0002] The cleaning machine's filter is a device that removes metal debris from the cleaning fluid. During the filtration process, if the filter becomes contaminated with metal particles, it loses its filtering effect and needs to be replaced. Remove the filter from the filter tank and perform maintenance outside the machine.

[0003] Because the filter tank is located at the top of the cleaning machine, replacing it requires two operators: one operator lowers the filter from the top of the cleaning machine, and the other operator receives the filter from the bottom. Furthermore, to prevent metal debris from falling off the filter, the filter needs to be wrapped with plastic film during this process.

[0004] This process has the following problems:

[0005] (1) It requires two operators to work together, which is time-consuming and labor-intensive.

[0006] (2) There are safety hazards in the transfer process of the filter. If the operator above drops the filter and the operator below fails to catch it, it will hit the operator below, causing work-related accidents and damage to the filter.

[0007] (3) During the replacement process, the filter screen will be covered with metal debris particles and cleaning fluid and will fall to the ground, affecting the working environment.

[0008] Based on this, it is expected to provide a cleaning machine filter lifting platform, which can realize the lifting and lowering of the filter and cover the filter in the process to prevent metal debris particles and cleaning liquid from falling. Summary of the Invention

[0009] The purpose of the present invention is to provide a filter lifting platform for a cleaning machine, which can realize the lifting and lowering of the filter through the device, thereby avoiding manual operation of two operators, and during the descent of the filter, the filter can also be covered at the same time to prevent metal debris particles and cleaning liquid from falling.

[0081] Continue reading Figure 15 and Figure 17 In some preferred embodiments, the filter screen lifting platform of the cleaning machine further comprises:

[0082] The first pallet slider 141 and the second pallet slider 142 are respectively arranged on the first pallet inclined slide 51 and the second pallet inclined slide 52; the first pallet inclined slide guide rod 151 and the second pallet inclined slide guide rod 152 respectively pass through the first pallet slider 141 and the second pallet slider 142 through the holes thereon, and the first pallet inclined slide guide rod 151 and the second pallet inclined slide guide rod 152 are both arranged on the bracket 1, and the first pallet slider 141 and the second pallet slider 142 can slide up and down along the first pallet inclined slide guide rod 151 and the second pallet inclined slide guide rod 152 in the height direction of the bracket 1 respectively, so as to provide a guiding effect on the up and down sliding of the first pallet inclined slide 51 and the second pallet inclined slide 52.

[0083] Continue reading Figure 2 In some preferred embodiments, the filter screen lifting platform of the cleaning machine further includes: a lower tray bracket 27, which is hinged to the lower tray 26 through the lower tray support frame shaft 3 to be opened or recovered relative to the lower tray 26.

[0084] like Figure 19 As shown, in this way, the filter screen lifting platform of the cleaning machine of the present invention is used:

[0085] The action of the cylinder rod of the tray driving cylinder 2 will drive the first tray inclined slide 51 and the second tray inclined slide 52 to move synchronously relative to each other in the height direction of the bracket 1, thereby causing the upper tray ejection pin 91 and the lower tray ejection pin 92 to move synchronously relative to each other in the horizontal direction, so that the upper tray 13 and the lower tray 26 are synchronously extended or retracted horizontally from the bracket 1.

[0086] The filter 23 removed from the cleaning machine is transferred to the filter receiving rod 24 via the upper tray 13. The plastic film on the filter coating roller 30 is fixed to the filter 23. The hanging basket lifting drive cylinder 17 is then activated, driving the filter coating drive slider 19 to move along the filter coating drive slider guide rod 16, driving the hanging basket 22 to descend. During the descent of the hanging basket 22, the meshing of the filter coating gear 201 and the filter coating rack 29 causes the filter coating gear 201 and the filter coating gear shaft 203 to rotate coaxially, thereby driving the filter coating roller 30 to rotate about the filter coating gear shaft 203 via the filter coating bent rod 28, thereby coating the filter with a film.

[0087] When the hanging basket 22 moves downward to the longest limit of the wire rope, it stops moving, cuts the plastic film, loosens the bolts on the filter screen receiving rod limit block 25, pulls out the filter screen receiving rod 24, and places the filter screen 23 coated with plastic film on the lower tray 26, waiting to be transported away.

[0088] The combination of the various technical features in this case is not limited to the combination described in the claims of this case or the combination described in the specific embodiments. All technical features recorded in this case can be freely combined or combined in any way unless there is a contradiction between them.

[0089] It should also be noted that the above-listed embodiments are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above-listed embodiments. Similar variations or modifications that can be directly derived from or easily conceived by those skilled in the art based on the disclosure of the present invention should fall within the scope of protection of the present invention.
