Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift battery equipment technology, specifically a lifting mechanism for a forklift battery. Background Technology
[0002] Existing forklift batteries are typically stored directly in the forklift's fixed battery compartment, which has limited space and lacks effective lifting assistance. When replacing or maintaining batteries, the large size and weight of the batteries pose significant safety hazards for manual operation, easily leading to operator injury. Furthermore, the traditional open design of the battery compartment requires lifting equipment for battery removal and insertion, but in many work scenarios, limited lifting space cannot meet the lifting needs, making battery replacement difficult. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a lifting mechanism that can simplify the forklift battery replacement process, improve operational safety and adapt to limited space, and can solve the problems in the prior art.
[0004] This utility model is achieved through the following technical solution: A lifting mechanism for a forklift battery of this utility model includes a housing, an internal support is provided inside the housing, characterized in that an inner cavity is provided inside the top plate, a bottom cavity is provided at the bottom of the inner cavity, a forklift battery is placed inside the inner cavity, and a lifting plate is provided inside the bottom cavity and the inner cavity, the plate being able to be lifted and lowered within the bottom cavity and the inner cavity by a driving device.
[0005] In a further technical solution, a top plate is provided on the top of the internal support, and the top plate closes the top side of the box.
[0006] A further technical solution includes a driving device comprising multiple sliding rods disposed on both sides of the internal support, a lifting plate slidably disposed on the outer surface of the sliding rods, the lifting plate being fixedly connected to the flat plate, a threaded shaft disposed between the sliding rods, the threaded shaft being rotatably disposed between the top plate and the internal support, the threaded shaft being threadedly connected to the lifting plate, and a power component for driving the threaded shaft to rotate being disposed at the bottom of the internal support.
[0007] A further technical solution includes a power assembly comprising two worm gear reducers disposed within the internal support. The worm gear shafts of the worm gear reducers are connected to the threaded shaft via a coupling, and a worm is disposed within each worm gear reducer.
[0008] A further technical solution also includes a connecting shaft, which connects the worm gears in the worm gear reducers on both sides.
[0009] In a further technical solution, a rectangular hole is provided inside the worm gear.
[0010] In a further technical solution, a perforation is provided inside the housing, through which the worm gear rotates.
[0011] In a further technical solution, a baffle is provided on the top of the flat plate, and after the forklift battery is installed in the inner cavity, the baffle abuts against the side of the forklift battery.
[0012] The beneficial effects of this utility model are:
[0013] 1. By providing through holes in the housing, it is convenient for personnel to operate and rotate the worm gear. When a rectangular hole is provided in the worm gear, personnel can use an external hex wrench to engage with the rectangular hole in the worm gear, making it convenient for personnel to rotate the worm gear.
[0014] 2. After the seat is flipped over, sufficient space is provided for the forklift battery to be lifted. The power connection between the worm gear reducers allows the worm gear reducers to synchronously drive the threaded shaft to rotate. After the threaded shaft rotates, it drives the lifting plate, flat plate and baffle to rise and fall synchronously, making it easy for personnel to take the forklift battery out of the box or put it in, avoiding insufficient lifting space that may affect the installation of the forklift battery.

[0023] like Figures 1-6 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of the forklift battery is consistent in the up, down, left, right, front and back directions.

The plate 31 can be lifted and lowered in the bottom cavity 23 and the inner cavity 22 by a driving device.
[0024] Advantageously, the top of the housing 11 is provided with a hinge seat 53, and a seat 52 is hingedly provided in the hinge seat 53. The seat 52 is a forklift seat. After the personnel flip the seat 52, the forklift battery can be lifted to leave enough space.
[0025] Advantageously, it also includes a tool 51, which is provided with a protrusion corresponding to the worm 33. The protrusion engages with a rectangular hole inside the worm 33 to enable the worm 33 to rotate.
[0026] Advantageously, the driving device includes multiple slide rods 37 disposed on both sides of the internal support 21, a lifting plate 36 is slidably disposed on the outer surface of the slide rods 37, the lifting plate 36 is fixedly connected to the plate 31, a threaded shaft 38 is disposed between the slide rods 37, the threaded shaft 38 is rotatably disposed between the top plate 13 and the internal support 21, the threaded shaft 38 is threadedly connected to the lifting plate 36, and a power component is disposed at the bottom of the internal support 21 to drive the threaded shaft 38 to rotate.
