Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a counterweight for a semi-electric stacker. Background Art

[0002] Stackers include pallet stackers, wide-leg stackers and counterbalance stackers, etc. The counterbalance stacker is provided with a counterweight at the rear end to balance the forks at the front end.

[0003] The weight and position of the counterweight of existing counterbalanced stackers are usually fixed. Although this method does not affect the overall stacking work of the stacker, when the stacker faces cargo that is heavier than its own counterweight, it is difficult to stack effectively. If the stacking is forced, it is likely to cause certain safety hazards. If the stacker is replaced, it will relatively delay the user's time.

[0004] Therefore, the existing demand is not met, and we have proposed a counterweight for a semi-electric stacker. Utility Model Content

[0015] The utility model has the following beneficial effects:

[0016] 1. The semi-electric stacker uses a counterweight. When the stacker is stacking goods, if the weight of the goods is greater than the weight of the counterweight, it makes it difficult to lift the goods. At this time, the counterweight is moved away from the gantry. According to the lever principle, when the counterweight is away from the gantry, the resistance torque will be extended. In this way, not only can the stacking of overweight goods be met without changing the weight of the counterweight, but the overall weight of the stacker is also reduced to a certain extent, thereby improving the flexibility of the stacker to a certain extent.

[0017] 2. The counterweight for the semi-electric stacker has a connecting rod between the two pulleys, so when the counterweight moves inside the first slide groove, the connecting rod will gradually approach the plug block set on the second balance plate. When the connecting rod and the plug block are close to each other, the second balance plate can be moved away from the gantry. At the same time, since a slide rail is also provided in the second balance plate, the moving distance of the counterweight can be extended within a certain range. BRIEF DESCRIPTION OF THE DRAWINGS
