Specific embodiment
As in Fig. 1 ~ 3, a kind of tire crane with moving counterweight system, moving counterweight 401 passes through connecting rod 402 and vertical shaft
404 are fixedly connected, and the top of vertical shaft 404 is provided with fluted disc 403,
Vertical shaft is located near the position of the afterbody of fixed seat 5, and drive device is connected with fluted disc 403, is driven by fluted disc 403 vertical
Axle 404 and moving counterweight 401 rotate.Thus structure, when construction, drives vertical shaft 404 to rotate by drive device, makes moving counterweight
401 are located at as, near the position of the afterbody of fixed seat 5, so as to extend the arm of force of counterweight, advantageously reduced tire crane in Fig. 2
Balance weight.After tested, on the premise of lifting amount is not reduced, 25 ~ 30% overall balance weights are alleviated, energy consumption are greatly reduced,
Improve traveling mobility.In this example, fixed seat 5 also serves as a part for counterweight.Afterbody in this example is to join with car body 1
According to thing, the right side in such as Fig. 1 is the afterbody of fixed seat 5.
Preferably, locking device is provided with the free end of moving counterweight 401, for the moving counterweight 401 for opening both sides
Lock together.
Preferred scheme is provided with top board 51 as shown in Fig. 1,3 in the position at the middle part of fixed seat 5, square under top board 51
Into the cavity for accommodating moving counterweight 401.Thus structure, is easy to receive moving counterweight 401, the top board of setting when not constructing
51 structures can carry such as generator, become inclination angle winding plant 7 and lifting winding plant 8.
Preferred scheme as shown in Figure 3, the connecting rod 402 being connected with moving counterweight 401, positioned at the middle part elevation of fixed seat 5
Position, make stress equalization, and connecting rod 402 do not interfere with the top of fixed seat 5 for making arm 9 change the support 6 at inclination angle
Arrangement.
As shown in Figure 3, described vertical shaft 404 passes through the first roller bearing 409 and the second roller bearing to preferred scheme
411 supportings, the first roller bearing 409 and the second roller bearing 411 are located above and below connecting rod 402 respectively.Thus structure,
Make the stress reliability of vertical shaft 404, and rotary resistance is small, is easy to control.
Preferred scheme as shown in Figure 3, is additionally provided with thrust bearing 410 between vertical shaft 404 and fixed seat 5.Thus tie
Structure, makes the rotation of vertical shaft 404 more smooth, and stress is also more reliable.
As shown in Figure 3, in described drive device, motor 408 is connected preferred scheme with worm screw 407, worm screw 407 and
The engagement connection of worm gear 406, worm gear 406 is connected by power transmission shaft 412 with travelling gear 405, and travelling gear 405 is nibbled with fluted disc 403
Close connection.Using worm-and-wheel gear, can be while big retarding ratio be realized, the effect with self-locking, it is to avoid moving counterweight 401
It is affected by gravity and swings.In this example, travelling gear 405 is respectively positioned under top board 51 with fluted disc 403, so as in fixed seat 5
Top reserves the larger space for advancing equipment.Power transmission shaft 412 passes through top board 51, upper end and the worm gear 406 of power transmission shaft 412
Connection, the lower end of power transmission shaft 412 is connected with travelling gear 405, and travelling gear 405 is supported by two bearings.
As shown in Figure 3, fixed seat 5 is tensed preferred scheme between each layer using the structure of multiple-level stack by bolt.
The sandwich construction of fixed seat 5 itself can be used as counterweight, it is preferred to use cast iron casting is formed, using the structure of multiple-level stack, just
In installation miscellaneous part, such as vertical shaft 404, fluted disc 403 and thrust bearing 410.
Location structure is provided between each layer of fixed seat 5, thus structure, is easy to being accurately positioned between each layer fixed seat,
It is beneficial to miscellaneous part, such as installation of vertical shaft 404.
Moving counterweight device 4 of the invention need not simultaneously rotate to the afterbody of fixed seat 5, only at the inclination angle of arm 9 every time
Excessive, the larger occasion of lifting weight just rotates moving counterweight device 4.Therefore need by automatically controlling, setting activity is matched somebody with somebody
Refitting is put 4 and enables strategy.
In optional scheme such as Fig. 1, fixed seat 5 is arranged on turntable 3, and the change He of inclination angle winding plant 7 is provided with turntable 3
Lifting winding plant 8, arm 9 is hinged with turntable 3, and suspension hook 10 is provided with arm 9；

In the alternative, it is provided with the pressure sensor for detecting the weight of suspension hook 10 in the upper end of arm 9；In arm
9 are provided with obliquity sensor with the position that turntable 3 is hinged.In this example, pressure sensor and the inclination angle of arm 9 by suspension hook 10,
Calculate hoisting heavy gravity be multiplied with the arm of force after, if more than setting value, when setting value is reached, then make change inclination angle elevator
Device 7 and lifting winding plant 8 stop, while the motor 408 in moving counterweight device 4 starts, drive vertical shaft 404 to rotate, and make
Moving counterweight 401 is rotated to the afterbody of fixed seat 5, so as to realize dynamic balance.It is further preferred that during lifting, according to
The inclination angle of arm 9, motor 408 drives moving counterweight 401 to be located at different positions, so as to realize the dynamic flat of gravity with hoisting heavy
Weighing apparatus, with the service life of extension device.For example under dynamic balancing operating mode, toothed disc on column 2 it is corresponding to the abrasion of gear compared with
It is low.
In another optional scheme, spiral supporting leg 11 is provided with the corner of car body 1, spiral supporting leg 11 is provided with for detecting
The pressure sensor of pressure, angle-position encoder is provided with the position of column 2.By the pressure sensor on spiral supporting leg 11
Angle-position encoder is coordinated to control moving counterweight device 4.Specifically, by determining the pressure of each pressure sensor, and utilize
Difference between pressure sensor is controlled.For example when two, the front pressure of pressure sensor and two, rear pressure sensing
Difference between device is more than setting value, and angle-position encoder display turntable 3 is located at initial position, then start moving counterweight device 4,
Realize gravitational equilibrium.According to the change of hoisting weight, the position of corresponding adjustment moving counterweight device 4, to realize that gravity is dynamically flat
Weighing apparatus.
In another optional scheme, the pressure sensor for detecting the weight of suspension hook 10 is provided with the upper end of arm 9；Hanging
Arm 9 is provided with obliquity sensor with the position that turntable 3 is hinged.The inclination angle of arm 9 is controlled by becoming inclination angle winding plant 7.Rolled up by lifting
Raise the lifting that device 8 controls suspension hook.Become inclination angle winding plant 7 and lifting winding plant 8 completes slinging work by work compound.
Spiral supporting leg 11 is provided with the corner of car body 1, the pressure that spiral supporting leg 11 is provided with for detecting pressure is passed
Sensor, angle-position encoder is provided with the position of column 2.The pressure sensor and obliquity sensor of wherein suspension hook 10 are mainly used to control
The position of moving counterweight device 4 processed.And pressure sensor on spiral supporting leg 11 to coordinate angle-position encoder to be then set to larger
Interval range is excited, as the safeties when the pressure sensor of suspension hook 10 and obliquity sensor control are failed.To enter
One step improves security.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Technical characteristic in the technical scheme that bright protection domain should be recorded with claim, including the technical scheme of claim record
