Abstract
The present invention discloses a liftable column fixation type rotation cantilever crane, wherein a rotation arm is arranged on a lifting support column and is provided with a rotation device, a vertical column comprises a fixed support column and the lifting support column, the lifting support column is arranged inside the fixed support column, the lower end of the fixed support column is connected with rollers through foundation bolts, an electric motor is embedded above the rollers, a hydraulic cylinder is arranged between the fixed support column and the lifting support column and is provided with two connection end heads, one end is connected with the fixed support column, the other end is connected with the lifting support column, and the top end of a plunger is connected with the lifting support column. According to the present invention, the piston type hydraulic cylinder is selected and has advantages of simple structure, long stroke and the like, such that the interference between the stretching of the hydraulic cylinder top rod and the lifting of the lifting support column due to the assembly error is effectively avoided.
Description
Technical field
The present invention relates to crane facility field, especially a kind of liftable fixed column type hinged cantilever hoisting crane.
Background technology
Fixed pillar type cantilever crane comprises column, revoliving arm and electric block, and column lower end is fixed in concrete foundation by holding-down bolt, and revoliving arm can around column revolving, and electric block makes left and right linear running on revoliving arm I-beam section, and hoisting heavy.This hoisting crane is the middle-size and small-size hoisting equipment that developed recently gets up, and possesses the features such as efficient, energy-conservation, time saving and energy saving, flexible.The light-duty lifting mode boom crane of this invention comprises in joint under hydraulic chain lifting device, crane arm, rack-and-gear lifting device, crane arm joint, crane arm saves, and saves right-hand end under described hydraulic chain lifting device is positioned at crane arm.First crane arm is holded up during work, then utilizes rack-and-gear lifting device to regulate joint height on crane arm, utilize that hydraulic chain lifting device regulates in crane arm, upper joint highly, finally crane arm is fixed.This light-duty lifting mode boom crane is a kind of portable jib crane, aims at the technological transformation of the part primary equipment of substation and installation and designs.This type hoisting crane volume is little, is convenient to move and pass through equipment, can carry out replacing and the installation of less than 1 ton primary equipment.But this light-duty lifting mode boom crane complex structure, hoisting capacity is difficult to accomplish more than 1 ton.Fixed pillar type cantilever crane has the not replaceable effect of portable jib crane, it has the advantages such as structure is simple, easy to operate, revolution is flexible, working space is large, hoisting capacity generally can reach 2 tons to 5 tons, be widely used in the loading and unloading work of the manufacturing line in workshop, fitting line and lathe, and the weight handling of the occasion such as warehouse, harbour.The height of the revoliving arm of fixed pillar type cantilever crane is fixing, encounters the situation that lifting altitude is higher or object oneself height is higher of handling object, needs to solve by miscellaneous equipment is auxiliary.And under the prerequisite of not sacrificing the advantages such as said structure is simple, hoisting capacity is large, how to make the height of the revoliving arm of fixed pillar type cantilever crane can adjust, prior art does not also have solution at present yet.
Summary of the invention
For the problems referred to above, the present invention aims to provide a kind of liftable fixed column type hinged cantilever hoisting crane.
For realizing this technical purpose, the solution of the present invention is: a kind of liftable fixed column type hinged cantilever hoisting crane, comprise revoliving arm, lifting pillar stiffener, fixed pedestal post, plunger, hydraulic actuating cylinder, slewing arrangement, electrical motor, roller, described revoliving arm is arranged on lifting pillar stiffener, revoliving arm is provided with slewing arrangement, described column comprises fixed pedestal post and lifting pillar stiffener, wherein be elevated pillar stiffener and be arranged on fixed pedestal post inside, the lower end of fixed pedestal post is connected with roller by holding-down bolt, electrical motor is inlaid with above roller, described hydraulic actuating cylinder is arranged between fixed pedestal post and lifting pillar stiffener, hydraulic actuating cylinder has two connection ends, one end is connected with fixed pedestal post, the other end is connected with lifting pillar stiffener, the top of described plunger is connected with lifting pillar stiffener.
As preferably, described hydraulic actuating cylinder is plunger-type cylinder.
The present invention selects plunger-type cylinder, and plunger-type cylinder has the advantages such as structure is simple, forced stroke is long, and actv. avoids the interference between the lifting of the flexible of the hydraulic actuating cylinder push rod caused because of assembly error and lifting pillar stiffener.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, the one liftable fixed column type hinged cantilever hoisting crane of the embodiment of the present invention, comprise revoliving arm 1, lifting pillar stiffener 2, fixed pedestal post 3, plunger 4, hydraulic actuating cylinder 5, slewing arrangement 6, electrical motor 7, roller 8, described revoliving arm 1 is arranged on lifting pillar stiffener 2, revoliving arm 1 is provided with slewing arrangement 6, described column comprises fixed pedestal post 3 and lifting pillar stiffener 2, wherein be elevated pillar stiffener 2 and be arranged on fixed pedestal post 3 inside, the lower end of fixed pedestal post 3 is connected with roller 8 by holding-down bolt, electrical motor 7 is inlaid with above roller 8, described hydraulic actuating cylinder 5 is arranged between fixed pedestal post 3 and lifting pillar stiffener 2, hydraulic actuating cylinder 5 has two connection ends, one end is connected with fixed pedestal post 3, the other end is connected with lifting pillar stiffener 2, the top of described plunger 4 is connected with lifting pillar stiffener 2.
As preferably, described hydraulic actuating cylinder 5 is plunger-type cylinder.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
