Detailed description of the invention
As in Fig. 1 ~ 3, a kind of tire crane with moving counterweight system, moving counterweight 401 is fixedly connected with vertical shaft 404 by connecting rod 402, and the top of vertical shaft 404 is provided with fluted disc 403,
Vertical shaft is positioned at the position near permanent seat 5 afterbody, and actuating device is connected with fluted disc 403, drives vertical shaft 404 and moving counterweight 401 to rotate by fluted disc 403.Structure thus, when constructing, drives vertical shaft 404 to rotate by actuating device, moving counterweight 401 is arranged in if Fig. 2 is near the position of permanent seat 5 afterbody, thus extends the arm of force of counterweight, be conducive to the balance weight reducing tire crane.After tested, under the prerequisite not reducing lifting amount, alleviate 25 ~ 30% overall balance weights, significantly reduce energy consumption, improve traveling manoevreability.In this example, permanent seat 5 is also as a part for counterweight.Afterbody in this example is with car body 1 for object of reference, as the right side in Fig. 1 is the afterbody of permanent seat 5.
Preferably, be provided with latching device at the free end of moving counterweight 401, lock together for the moving counterweight 401 that both sides are opened.
Preferred scheme, as shown in Fig. 1,3, is provided with top board 51 in the position at the middle part of permanent seat 5, forms the cavity for holding moving counterweight 401 below top board 51.Structure thus, is convenient to receive moving counterweight 401 when not constructing, and top board 51 structure of setting can carry such as electrical generator, change inclination angle winding plant 7 and lifting winding plant 8.
As shown in Figure 3, the connecting rod 402 be connected with moving counterweight 401, is positioned at the position of elevation in the middle part of permanent seat 5, makes stress equalization preferred scheme, and connecting rod 402 can not affect the layout for making arm 9 change the support 6 at inclination angle at permanent seat 5 top.
As shown in Figure 3, described vertical shaft 404 is supported by the first cylindrical bearing 409 and the second cylindrical bearing 411 preferred scheme, and the first cylindrical bearing 409 and the second cylindrical bearing 411 lay respectively at above and below connecting rod 402.Structure thus, make the reliably stressed of vertical shaft 404, and rotary resistance is little, is convenient to control.
Preferred scheme as shown in Figure 3, is also provided with thrust baring 410 between vertical shaft 404 and permanent seat 5.Structure thus, makes the rotation of vertical shaft 404 more smooth, stressed also more reliable.
As shown in Figure 3, in described actuating device, motor 408 is connected with worm screw 407 preferred scheme, and worm screw 407 and worm gear 406 are connected with a joggle, and worm gear 406 is connected with transmission gear 405 by transmission shaft 412, and transmission gear 405 and fluted disc 403 are connected with a joggle.Adopt worm-and-wheel gear, while realizing big retarding ratio, the effect of self-locking can be had, avoid moving counterweight 401 be affected by gravity and swing.In this example, transmission gear 405 and fluted disc 403 are all positioned under top board 51, thus reserve the larger space for advancing equipment at permanent seat 5 top.Transmission shaft 412 is through top board 51, and the upper end of transmission shaft 412 is connected with worm gear 406, and the lower end of transmission shaft 412 is connected with transmission gear 405, and transmission gear 405 is by two bearing supportings.
As shown in Figure 3, permanent seat 5 adopts the structure of multiple-level stack to preferred scheme, is strained between each layer by bolt.The multiple-structure of permanent seat 5 self as counterweight, preferably can adopt cast iron casting to form, adopts the structure of multiple-level stack, be convenient to install miscellaneous part, such as vertical shaft 404, fluted disc 403 and thrust baring 410.
Be provided with location structure between each layer of permanent seat 5, structure thus, be convenient to the accurate location between each layer permanent seat, be beneficial to miscellaneous part, such as the installation of vertical shaft 404.
Moving counterweight device 4 of the present invention does not need the afterbody at every turn all rotated to permanent seat 5, and only excessive at arm 9 inclination angle, the occasion that lifting weight is larger just makes moving counterweight device 4 rotate.Therefore need by automatic control, what set moving counterweight device 4 enables strategy.
Optional scheme is as in Fig. 1, and permanent seat 5 is arranged on turntable 3, and turntable 3 is provided with and becomes inclination angle winding plant 7 and lifting winding plant 8, arm 9 is hinged with turntable 3, arm 9 is provided with suspension hook 10;
