Abstract
The utility model discloses an unfolding balance weight device of a pipelayer. A balance weight bracket is fixed together with a stander, the balance weight device is provided with a primary cantilever, a secondary cantilever, a primary oil cylinder, and a secondary oil cylinder, wherein, the primary cantilever is hinged with the balance weight bracket through a primary cantilever pin roll, the secondary cantilever is hinged with the primary cantilever through a secondary cantilever pin roll, and each balancing weight is connected with the secondary cantilever through two balance weight pin rolls; one end of the primary oil cylinder is connected with the stander through an oil cylinder pin roll, and the other end is connected with the primary cantilever through an oil cylinder pin roll; one end of the secondary oil cylinder is connected with the primary cantilever through an oil cylinder pin roll, and the other end is connected with the secondary cantilever through an oil cylinder pin roll; the axes of all the pin rolls are in the vertical direction. The unfolding balance weight device has long unfolding distance and light balance weight, thereby the whole device has light weight; the weight of the balance weight does not need to be overcome in the process of unfolding and folding, and the load of the oil cylinder is little.
Description
Technical field:
The utility model relates to a kind of counter weight device that is mainly used in pipe sling, especially a kind of pipe sling expansion equation counter weight device.
Background technology:
The counterweight form of pipe sling mainly is that one-level is vertically launched now, and development distance is short, and counterweight weight is big, thereby causes complete machine weight big; Need to overcome counterweight weight in the counterweight gathering process, the oil cylinder load is big.
Summary of the invention:
The purpose of this utility model provides a kind of pipe sling expansion equation counter weight device, overcomes above the deficiencies in the prior art, and development distance is long, and counterweight weight is little, thereby complete machine weight is little; Counterweight is launched to need not to overcome counterweight weight in the gathering process, and the oil cylinder load is little.
The purpose of this utility model realizes as follows: it relates to counterweight support, cantilever, clump weight, counterweight support and frame are fixed together, it is hinged by one-level cantilever bearing pin and counterweight support to be provided with the one-level cantilever, it is hinged by secondary cantilever bearing pin and one-level cantilever to be provided with the secondary cantilever, and each clump weight is connected with the secondary cantilever by the counterweight bearing pin; Be provided with one-level oil cylinder one end and be connected with frame by the oil cylinder bearing pin, the other end is connected with the one-level cantilever by the oil cylinder bearing pin; Be provided with two-level oil cylinder's one end and be connected with the one-level cantilever by the oil cylinder bearing pin, the other end is connected with the secondary cantilever by the oil cylinder bearing pin; The axis of one-level cantilever bearing pin, secondary cantilever bearing pin, counterweight bearing pin and oil cylinder bearing pin is a vertical direction.
One-level cantilever and counterweight support hinged place, secondary cantilever and one-level cantilever hinged place are provided with thrust baring.
In sum, the principal feature of this utility model is: have the two-stage cantilever, clump weight is positioned on the secondary cantilever; Have two oil cylinders, the one-level that is respectively applied for counterweight is launched, secondary launches and gathering; The bearing pin axis is a vertical direction, launches so counterweight is carried out two-stage in horizontal surface; Thrust baring is equipped with in bearing pin position at counterweight support and one-level cantilever, the friction drag when rotating to reduce.
During the elongation of one-level oil cylinder, the one-level cantilever drives the secondary cantilever and clump weight outwards carries out the one-level horizontal development; When two-level oil cylinder extended, the secondary cantilever drove clump weight and outwards carries out the secondary horizontal development; When two-level oil cylinder shortened, the secondary cantilever drove clump weight and inwardly carries out the gathering of secondary level; When the one-level oil cylinder shortened, the one-level cantilever drives the secondary cantilever and clump weight inwardly carries out the gathering of one-level level.
The beneficial effects of the utility model are: development distance is long, and counterweight weight is little, thereby complete machine weight is little; Counterweight is launched to need not to overcome counterweight weight in the gathering process, and the oil cylinder load is little.
Description of drawings:
Fig. 1 is the front view of the utility model pipe sling expansion equation counter weight device.
Fig. 2 is the birds-eye view of the utility model pipe sling expansion equation counter weight device.
The specific embodiment:
With reference to Fig. 1, Fig. 2, counterweight support 1 is fixed together with frame, it is hinged with counterweight support 1 by one-level cantilever bearing pin 5 and thrust baring 7 to be provided with one-level cantilever 2, it is hinged with one-level cantilever 2 by secondary cantilever bearing pin 6 and thrust baring 7 to be provided with secondary cantilever 3, and each clump weight 4 is connected with secondary cantilever 3 by 2 counterweight bearing pins 8; Be provided with one-level oil cylinder 9 one ends and be connected with frame by oil cylinder bearing pin 11, the other end is connected with one-level cantilever 2 by oil cylinder bearing pin 11; Be provided with two-level oil cylinder's 10 1 ends and be connected with one-level cantilever 2 by oil cylinder bearing pin 11, the other end is connected with secondary cantilever 3 by oil cylinder bearing pin 11; The axis of one-level cantilever bearing pin 5, secondary cantilever bearing pin 6, counterweight bearing pin 8, oil cylinder bearing pin 11 is a vertical direction.I, the II at clump weight 4 places, III position among the figure are respectively the different conditions that counterweight is in gathering, one-level expansion, secondary expansion.
