The specific embodiment
Referring to Fig. 1-Fig. 4, Fig. 1 illustrates the utility model hoisting crane lifting state, and Fig. 2 illustrates the transition state of the utility model hoisting crane, and Fig. 3 illustrates the crane arm of hoisting crane, and Fig. 4 illustrates the telescopic column of hoisting crane.
The main element of hoisting crane 10 comprises crane arm 1, truss 2, telescopic column 3, pull bar 4, caterpillar belt structure 5, supporting leg 6, barrel base 7 and chassis 8.Crane arm 1 is hinged on the lifting platform 11, and the amplitude oil cylinder 12 on the lifting platform 11 is connected crane arm 1 near bottom position, for crane arm 1 provides a fulcrum.During work, by regulating the support angle of amplitude oil cylinder 12, the angle that scalable crane arm 1 stretches out.Crane arm 1 is the telescoping structure, and flexible joint number is preferably 4, during work, can need the flexible joint number of transport distance change crane arm 1 according to the lifting object, to adjust the length of crane arm 1.
Truss 2 is made up of support 21 intersections of two " one " fonts, and it is centered close to crane arm 1 below, and four pull bars 4 are fixed in the end of two supports 21.Truss 2 can be when crane arm 1 lifting object, and firm telescopic column 3 allows crane arm 1 keep balance.
One end of telescopic column 3 is fixed on the chassis 8, and the other end is connected with truss 2 with crane arm 1, supports weighing arm 1 and truss 2.The stretching structure form of telescopic column 3 is a horizontal bar latch mode, and flexible joint number is preferably 6.By adjusting the flexible joint number of telescopic column 3, the height of adjustable and retractable arm 1 is to adapt to the camp site demand that requirement differs to sling height.
When walking, raise, do not have chassis 8 to influence hoisting crane 10 operations for preventing seawater as the water surface in the shallow sea, can start the hydraulic ram on each column 53, the actuating unit of 4 hydraulic rams stretches upwards, and four support beams 54 on jack-up chassis 8 allow chassis 8 also increase.Chassis 8 terrain clearances of the utility model hoisting crane 10 can reach 1.5-3.5 rice, make hoisting crane 10 strengthen the adaptive capacity to environment of hoisting crane 10 in shallow water area walking and operation.
Supporting leg 6 can be 4, is connected to the front and back end of 8 left and right sides, chassis, and during hoisting crane 10 walkings, supporting leg 6 is packed up; During hoisting crane 10 liftings, supporting leg 6 stretches out, and supports the total weight of whole hoisting crane 10.
For hoisting crane 10 is adapted in the relatively poor shoal area operation of ground supports power, the utility model is provided with barrel base 7 in the bottom of supporting leg 6.Barrel base 7 is the bigger barrel-shaped object of diameter, and inside is hollow structure.Supporting leg 6 is connected the bottom of barrel base 7, and barrel base 7 openings one end is downward.When the shoal area operation, the total weight of whole hoisting crane 10 is delivered on the barrel base 7 by barrel base 6, because ground-surface bearing force is relatively poor, the part of barrel base 7 can be pressed into subsurface, will strengthen the bearing force of barrel base 7 so greatly, make the supporting leg 6 can the whole hoisting crane 10 of firm support, make things convenient for hoisting crane 10 in the shoal area operation.
The utility model supporting leg 6 can adopt the stubborn solid mode of screw to be connected with barrel base 7, makes things convenient for installation, dismounting and the transportation of barrel base 7.
Under the transition state, truss 2 folding being placed on the chassis 8 of hoisting crane 10, column 3 also bounces back and drops to the ground, and pull bar 4 dismountings are folding, and barrel base 7 reclaims to be placed.(see figure 2).
Hoisting crane 10 is when the shallow water area operation, and when running into high tide, the depth of water surpasses 3m sometimes, and hoisting crane 10 is as can not in time withdrawing from, and the impact of wave can have a strong impact on equipment and personnel's safety, and tidewater will flood vehicle body, damage material and equipment etc.For addressing this problem, the utility model provides and helps floating device, air bag and air pump (not shown) are set on the chassis 8 of hoisting crane 10, when the depth of water during greater than safe water level, air pump starts, and is airbag aeration, and air bag provides buoyancy with caterpillar belt structure 5 for car load, hoisting crane 10 is floated assurance personnel and device security.Air bag is preferably 2.
Referring to Fig. 5-Fig. 8, Fig. 5 illustrates the oil cylinder and the caterpillar belt structure connection mode of hoisting crane that the utility model provides, and Fig. 6 illustrates caterpillar belt structure spatial structure provided by the utility model, and Fig. 7 is the I portion enlarged drawing of Fig. 6; Fig. 8 illustrates buoyancy tank spatial structure provided by the utility model.
The upper and lower surface of buoyancy tank 51 is the plane, and two ends, the left and right sides are provided with the groove 511 that is used to place drive wheel 56, and groove 511 is provided with two grabs 512 that are used to engage drive wheel 56.Caterpillar belt structure 5 adopts biliquid pressure motor type of drive, to strengthen the power of caterpillar belt structure 5.
Because of hoisting crane 10 of the present utility model has the floating box type caterpillar belt structure, can be in shoal area and shallow water area walking; The supporting leg of hoisting crane 10 is provided with barrel-shaped barrel base, can be at shoal area and shallow water area lifting operation, and have and help floating device, guarantee the safety of underwater work.Therefore, the utility model hoisting crane 10 is to adapt to shoal area and shallow water area, and the Amphibious crane of land area operation.
More than Amphibious crane provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
