The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the present invention can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As depicted in figs. 1 and 2, during concrete pump truck 1 normal walking, four supporting legs 10 in front and back, 11 are regained, and boom system is folding.When concrete pump truck 1 operation, at first counterweight support leg liner plate 2 is placed on supporting leg 10 before and after each, the 11 times suitable Support Positions.Article four, supporting leg 10,11 launches, and front leg strut oil cylinder 101 heads are locked on the counterweight support leg liner plate 2, and rear support leg oil cylinder 111 spherical head are locked on the counterweight support leg liner plate 2.At front and back support oil cylinder 101 and 111 concrete pump truck 1 is lifted, make the tire built on stilts.Concrete pump truck 1 beginning operation.
As shown in Figure 3, counterweight support leg liner plate 2 comprises counterweight element 20, Locking Device; Offer groove 24 on the counterweight element 20, groove 24 is used for cooperating with the head of support oil cylinder 101.When the head of support oil cylinder 101 inserted in the groove 24, Locking Device was used for the head of support oil cylinder 101 is locked at groove 24, and when the Locking Device release, the head of support oil cylinder 101 can be deviate from from groove 24.Locking Device comprises at least one latch 21, and counterweight element 20 is offered transverse holes, and transverse holes communicates with groove 24, and latch 21 is installed in the transverse holes and its first end can stretch in the groove 24.Preferably, Locking Device comprises that 21, two latches 21 of two latches are with the Central Symmetry layout of groove 24.Be set with retracing spring 22 on the latch 21, retracing spring 22 is used for the first end of described latch 21 is stretched in the groove 24, the first end of latch 21 is provided with the inclined-plane, when the head of support oil cylinder 101 inserts groove 24 when interior, the head conflict inclined-plane of support oil cylinder 101 makes the first end of latch 21 from groove 24 interior retractions.In the above-head of support oil cylinder 101 a locking plane can be set, when the head of support oil cylinder 101 inserts groove 24 and puts in place, the first end of latch 21 at retracing spring 22 above the locking plane of the head that is resisted against support oil cylinder 101 under the effect.The second end of latch 21 is equipped with for the handle 23 of the first end that drives latch 21 from groove 24 interior retractions.This bright Locking Device can also adopt the modes such as magnet attraction except adopting the latch mode.Locking Device is upper outside except being arranged on counterweight element, also can be arranged on the support oil cylinder, and perhaps a part is arranged on the counterweight element, and another part is arranged on the support oil cylinder, inserts energy locking in the groove as long as can realize when the head of support oil cylinder.
Counterweight support leg liner plate 2, it keeps outside original support backing plate function, the more important thing is, it can with supporting leg 10,11 interlocks, namely when supporting leg 10,11 does not have downward pressure, that is to say when supporting leg 10, when 11 support ground are unsettled, 2 of counterweight support leg liner plates have certain weight because of it, it has makes supporting leg 10,11 downward pulling force, and weight balance function is namely arranged, and keeps the stability of construction machinery and equipment.The weight of counterweight element 20 is for generally more than 100 kilograms or equal 100 kilograms.Counterweight support leg liner plate 2 is heavier, generally arranges by machinery counterweight support leg liner plate 2 is carried on supporting leg 10 before and after each, the 11 times suitable Support Positions.If counterweight support leg liner plate 2 is low weight, can't play the counterweight effect, only have supporting role.
As shown in Figure 4, the second counterweight support leg liner plate provided by the invention and different being of counterweight support leg liner plate shown in Figure 3, groove 24 is taper, the lower end of support oil cylinder 101 also is taper, with 24 corresponding cooperations of groove.
As shown in Figure 5, the 3rd counterweight support leg liner plate provided by the invention and different being of counterweight support leg liner plate shown in Figure 3, the bottom surface of groove 24 is the plane, the lower end of support oil cylinder 101 also is the plane, with 24 corresponding cooperations of groove.
Counterweight support leg liner plate 2 disclosed by the invention and concrete pump truck ballasting method can be applied to other mechanical equipment, such as hoisting crane.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
