Problems solved by technology

[0002] At present, the position and purpose of each hinge point of crawler cranes on the market are relatively fixed, and the expansion of lifting capacity is realized by adding super-lifting devices (super-lifting mast and super-lifting counterweight, etc.), but the super-lifting device is more than the original machine. There are many parts, the operating efficiency is greatly reduced, and these parts are inconvenient to manage when there is no need to overlift; the angle between the tower arm and the main arm of crawler cranes currently on the market is generally greater than 70 degrees. The angle between the main arms is generally 180 degrees, which requires a large and flat lifting site; the current commercially available dynamic compaction machine is a special type of crawler crane, all of which are single-arm type, and the compaction capacity without the mast It is only half of that with a gantry, but the gantry cannot be hoisted to walk with the tamper when the door is attached; there are fewer common parts among various types of crawler cranes on the market, and the manufacturing cost and management cost increase; the crawler cranes currently on the market Generally, corresponding auxiliary cranes are required for disassembly or maintenance, and the cost of use and maintenance is very high; the current commercially available crawler cranes wear the machine itself and the ground under the crawler shoes or the supporting box greatly when they turn in situ; the current commercially available crawler cranes On the ground with a slope greater than 1%, it is not allowed to lift heavy or lift to climb the slope

Embodiment 1

[0030] Example 1, such as figure 1 As shown in the figure, a humanoid tower stacking operation condition of a combined multifunctional crawler crane with variable hinge points is shown. The unit 2 and the multi-hinge connection unit 1 are connected by hinge pins, and the relative positions of the hinges are changed according to actual needs during the operation.

[0031] The multi-hinge connection unit 1 includes a multi-hinge main beam 4, a leg 5, a sliding bracket 6, and a power and control device 26; the outrigger 5 and the multi-hinge main beam 4 are hinged by telescopic sliding or rotating The sliding bracket 6 is connected with the load-bearing slideway 7 in the multi-hinged main beam 4 by sliding or rolling, and the power and operating device 26 is connected with the multi-hinged main beam 4 by hinges or bolts.

[0032] Described support leg 5 comprises movable support leg 8, vertical telescopic oil cylinder 9, support foot 10, and movable support leg 8 is fixedly con...

Embodiment 2

[0038] Example 2, such as figure 2 As shown, a T-shaped tower stacking operation condition of a combined multifunctional crawler crane with variable hinge points, the T-shaped tower stacking operation condition of the crawler crane includes a multi-hinge point connection unit 1, a walking slewing unit 2, and an operating unit 3; The walking turning unit 2 is connected with the multi-hinge point connection unit 1 by hinge pins, and the relative positions of the hinges are changed according to actual needs during the operation.

[0039] The parts and work included in the multi-hinge connection unit 1 and the walking and turning unit 2 are basically the same as those in the first embodiment.

[0040] The T-shaped stacking operation working unit 3 includes a connecting seat 31, a main boom root section 32, a main boom standard section 33, a transition section 34, a main boom head 35, a tower boom root section 36, a tower boom standard section 37, Tower arm head 38, main mast 39...

Embodiment 3

[0041] Example 3, such as image 3 As shown, a dual-hammer dynamic compaction working condition of a multifunctional crawler crane combined with variable hinge points, said crawler crane double-hammer dynamic compaction working condition includes a multi-hinge point connection unit 1 , a walking slewing unit 2 , and an operating unit 3 . The walking turning unit 2 is connected with the multi-hinge point connection unit 1 by hinge pins, and the relative positions of the hinges are changed according to actual needs during the operation.

[0042] The parts and work included in the multi-hinge connection unit 1 and the walking and turning unit 2 are basically the same as those in the first embodiment.

Abstract

The invention discloses a hinge points-variable combined type multi-functional crawler crane, belonging to the field of engineering machinery. The crawler crane comprises a multi-hinge point connecting unit 1, a walking rotation unit 2 and a work unit 3. The work unit 3 is connected with the multi-hinge point connecting unit 1 by one hinge pin, and the hinging relative position is confirmed when a working condition is selected, so that the multifunction of the crawler crane can be realized; and the walking rotation unit 2 is connected with the multi-hinge point connecting unit 1 by another hinge pin, and the hinging relative position is switched according to actual requirements in the process of working, so that the work capability of the crawler crane can be improved. The hinge points-variable combined type multi-functional crawler crane has an assistant crane function, so that the problem that a machine body, a ground surface under a crawler plate or a support box are seriously worn when the crawler crane rotates in situ can be perfectly solved, and the hoisting work on a slope or the climbing by means of suspended load can be realized. Compared with the work condition of a tower arm in the current market machine, the work condition of a reverse V-shaped overlapped tower is higher in hoisting capacity; and compared with the work efficiency of the work condition of the current market machine, the work efficiency of the double-hammer dynamic compaction work condition can be doubled.
