Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] In this document, the liquid may be a liquid with an appropriate density; based on the cost of the liquid and the convenience of acquisition, the liquid is preferably water.

[0034] Please refer to figure 1 , figure 1 It is a schematic diagram of the principle structure of the counterweight mechanism provided by the first embodiment of the present invention. The counterweight mechanism provided by this embodiment is used for mobile engineering machinery. The counterweight mechanism includes a box body 100 and a draft tube 200 fixed relatively to the box body 100 .

[0035] The tank 100 forms a liquid cavity 110 for containing liquid. The volume and shape of the liquid chamber 110 can...

Abstract

The invention discloses a movable engineering machine and a counter weight mechanism. The counter weight mechanism comprises at least one box and at least one flow guiding pipe relatively fixed with the at least one box. Every box forms a liquid cavity accommodating liquid, the lower end of the flow guiding pipe extends into the liquid cavity, a preset distance is reserved between the lower end of the flow guiding pipe and the bottom surface of the liquid cavity, and the upper end of the flow guiding pipe extends out of the liquid cavity. According to the optimized technical scheme, the inner section of every part of the flow guiding pipe parallel to the horizontal plane is equal, or areas of inner sections of the flow guiding pipe parallel to the horizontal plane are gradually increased in a direction from the lower end to the upper end. When liquid in the liquid cavity of the counter weight mechanism is solidified, due to the fact that the flow guiding pipe is arranged, drainage can be performed through the flow guiding pipe, box damage caused by largening of liquid solidification area is avoided or reduced, and reliability and stability of the counter weight mechanism are guaranteed.

Description

technical field [0001] The invention relates to counterweight technology, in particular to a counterweight mechanism, and also includes a mobile construction machine including the counterweight mechanism. Background technique [0002] In order to ensure balance, improve stability or other purposes, many construction machines are equipped with counterweight mechanisms. For example, mobile construction machinery such as dynamic compactors, cranes, forklifts, road rollers, and excavators can be equipped with counterweight mechanisms. [0003] The current counterweight mechanism can be formed by casting pig iron to form a block structure, and can also include a box and hardened concrete in the box to form a structure. With respect to the predetermined mobile construction machine, the counterweight should have an appropriate weight; when the counterweight mechanism is installed at an appropriate position on the body of the mobile construction machine, the counterweight should ge...
