Abstract
The utility model relates to a foldable hoisting machine which aims to solve the technical problem that the provided hoisting machine has the characteristics of succinct and reliable structural design, convenient disassembly and assembly and smaller occupied area. The foldable hoisting machine comprises a base with a traveling wheel installed at the bottom, an upright column hinged on the base and two supporting legs hinged on the base, and is characterized in that a cantilever is hinged on the upright column, a lifting hook is positioned at the top end of the cantilever, and both ends of an oil cylinder are respectively hinged on the upright column and the cantilever.
Description
Technical field
The utility model relates to a kind of elevator machinery, specifically is folding lifting machine.
Background technology
Chinese patent application file (application number 97204807.3) discloses a kind of foldable crane; This loop wheel machine comprises base, two supporting legs, column, cantilever, jack, road wheel is arranged at the bottom of supporting leg and base, the quantity of the road wheel of base lower end can support loop wheel machine and move freely, supporting leg connects to constitute to turn round with bearing pin with base to be paid, on supporting leg and the base knock hole is arranged, by the knock hole on supporting leg and the base, can become U-shaped to be fixed on level attitude with base supporting leg with latch, or supporting leg is fixed on the folding position with base after the bearing pin rotation is holded up.Because it is folding that the supporting leg of this machine can be holded up, so use more flexible.
The defective of this loop wheel machine is, loop wheel machine is changed between folded state and mode of operation needs a plurality of latches of dismounting, and adjusting work comparatively bothers; It is also succinct inadequately that it forms structure, makes work capacity and cost and all be difficult to further reduction, and it is inconvenient that transportation also seems.
The utility model content
Technical problem to be solved in the utility model provides a kind of improvement of foldable crane, and this loop wheel machine should be able to overcome the deficiency of above-mentioned background technology, has that decoration structure features simple design is reliable, dismounting and easy to assembly, a floor area features of smaller.
The technical scheme that the utility model proposes is: a kind of foldable crane, comprise that the bottom is equipped with on the base, base of road wheel two articulated legs on pivotally attached column and the base, it is characterized in that a hinged cantilever on the described column, a suspension hook is located on the cantilever top, and other has the two ends of an oil cylinder to be hinged on respectively on column and the cantilever.
Described two legs and base rotate hinged.
On described two legs road wheel is housed respectively also.
Folded state of the present utility model such as Fig. 4, shown in Figure 5, this moment, the volume of loop wheel machine was a minimum rating.Earlier two legs are become the splayed fork to keep the stable of center of gravity during assembling, pillar then pins with latch again after bearing pin up rotates and fixes, and just becomes Fig. 2, state shown in Figure 3; Only need to start oil cylinder work then, the piston rod of oil cylinder just orders about cantilever and rotates around jointed shaft gradually, reaches assigned address (cantilever basic horizontal state) until cantilever, the mode of operation position (as shown in Figure 1) of Here it is loop wheel machine.
The utility model is through optimal design, and complete machine structure is very succinct, and under the guaranteed prerequisite of reliability of service, the member of employing has tangible minimizing than background technology; The reliability of material mode of operation has assurance fully again; Complete machine is folding or also only need a latch on the dismounting pillar when recovering, and is very convenient quick; And when folded state, the floor area of complete machine is minimum, and this transportation and storage for loop wheel machine is very favourable.

Fig. 1 is the main TV structure scheme drawing of the utility model mode of operation.
Fig. 2 is the main TV structure scheme drawing of the cantilever folded state in the utility model.
Fig. 3 is the plan structure scheme drawing of the cantilever folded state in the utility model.
Fig. 4 is the main TV structure scheme drawing of the utility model at folded state.
Fig. 5 is the plan structure scheme drawing of the utility model at folded state.
The specific embodiment
As shown in the figure, the bottom of the base 2 of this kind foldable crane is equipped with road wheel 1 and (on the demonstration base 3 road wheels is housed among the figure; Road wheel quantity also can be determined as required), an also hinged column 3 and two legs 7 on the base; Its central post and base U-shaped plate 2-1 are hinged by a bearing pin 8-2, so column can rotate around bearing pin; Also be shaped on two knock hole 2-1-1 on the base U-shaped plate 2-1, when in these two knock holees, inserting latch (latch passes second through hole on the column simultaneously), just can make column keep the state of Fig. 1 or Fig. 3 respectively.Described two legs 7 and base pivotally attached jointed shaft axis are then perpendicular to ground; Such two legs just can rotate along horizontal surface around hinge axes respectively.The other end of two legs is also respectively installed a road wheel, makes the mobile more convenient of loop wheel machine.
The bottom of the also hinged cantilever 4 of the other end of described column (jointed shaft 8-1), (hinged by bearing pin) suspension hook 6 is then located on the top of cantilever, other has the two ends (being respectively oil cylinder bottom and piston rod top) of an oil cylinder 5 to be hinged on respectively on the column and on the cantilever, so that cantilever can rotate around hinge-point.
Claims (3)
1, a kind of foldable crane, comprise that pivotally attached column (3) is equipped with on the base (2), base of road wheel (1) in the bottom and base (2) is gone up articulated two legs (7), it is characterized in that a upward hinged cantilever (4) of described column (3), a suspension hook (6) is located on the cantilever top, and other has the two ends of an oil cylinder (5) to be hinged on respectively on column and the cantilever.
2, a kind of foldable crane according to claim 1 is characterized in that described two legs (7) and base (2) rotate hinged.
3, a kind of foldable crane according to claim 1 and 2 is characterized in that also respectively being equipped with on described two legs (7) road wheel.
