Description

A lift trolley

technical field

The utility model belongs to the field of short-distance production and transportation equipment, in particular to a lifting trolley.

Background technique

The production materials in the current factory workshop are transported from the warehouse to the material storage area of the production workshop or the head of the assembly line with a forklift on the pallet, and then the material boxes or materials are lifted to the truck and then transported to each station and lifted to the designated area. Special personnel are required The materials are replenished from time to time, but the height of the carts used for transferring the materials used is fixed and cannot be adjusted, and the materials need to be lifted repeatedly. This problem also exists if the materials are transferred directly with a forklift.

In the factory assembly line, the height of the materials stored at each station is roughly at the same level as the workbench at first for workers to take them easily. However, as the materials are consumed, it is necessary to bend down when taking the materials off the table. Currently, there are electric lifting platforms on the market because the motor takes power, which consumes energy and is inconvenient to move. The hydraulic lifting platform has a hydraulic pump, which is expensive to purchase and maintain, and the lifting process requires manual stepping on the switch.

Based on the above-mentioned development of a trolley that is convenient for lean production, the material flow and station materials are seamlessly connected to ensure that the materials are pushed and loaded at the lowest position without lifting, one-time loading and self-adapting to the operating height of the station, saving labor and effort. Convenience and energy saving.

2. The new model adopts tension spring group to balance the loading platform, which reduces the labor intensity of the operation and improves the loading capacity.

3. In this new type of elastic mechanism, the bottom fixed platform is equipped with adjusting bolts to adapt to different material weights for pre-adjustment, which improves the practicability of different weight materials and expands the scope of use of the trolley.

4. The height of the lowest loading platform of the new model will be consistent with the height of the standard pallet, so that the bottom material box or tray can be pushed directly onto the car without lifting; when the material is transported to the workbench, it only needs to be pedaled after the upper layer of material is used up. Brake pedal, then release the tension spring according to the height of the material box to rise to be level with the workbench until the bottom layer of material is used up.

5. A torsion spring is installed on the bottom fixed block of the elastic mechanism of the lower fixed frame to prevent the failure of the stretch spring group at the lowest position.

6. The utility model is equipped with two universal casters and two brake casters to facilitate movement and braking at any time.

7. The utility model can replace the heavy labor of human hands, reduce labor intensity, significantly improve production efficiency and save energy.
