Abstract

The utility model discloses a lifting fixed-column arm crane comprising a vertical column, wherein the vertical column comprises a fixed support column and a lifting support column assembled in the fixed support column along the vertical direction; and a hydraulic cylinder is arranged in the fixed support column and jacked between the fixed support column and the lifting support column. The lifting support column is lifted by means of the hydraulic cylinder and declined through the pull of the hydraulic cylinder, but generally depending on the self-weight of the lifting support column. The lifting fixed-column arm crane has the advantages that a rotary arm is lifted or declined through adjusting the length of the vertical column, so that the adjustment on the height of the rotary arm of the fixed-column crane is realized, the advantages of good lifting capacity and the like of conventional fixed-column arm cranes are not lost and the convenience is brought to the production operation of people.

Description

Liftable fixed column type boom crane

Technical field

The utility model relates to the crane facility field, relates in particular to a kind of liftable fixed column type boom crane.

Background technology

The fixed column type boom crane comprises column (also being fixed column), revoliving arm and electric block, column lower end is fixed on the concrete foundation by holding-down bolt, revoliving arm can be around column revolving, and electric block is made left and right sides linear running at the revoliving arm I-beam section, and hoisting heavy.This hoisting crane is middle-size and small-size the heavy equipment that developed recently gets up, and possesses characteristics such as efficient, energy-conservation, time saving and energy saving, flexible.

Granted publication number discloses a kind of light-duty lifting mode boom crane for the Chinese patent of CN 202358850 U.The light-duty lifting mode boom crane of this utility model comprises under hydraulic chain lifting device, the crane arm in joint, rack-and-gear lifting device, the crane arm and saving on joint, the crane arm that described hydraulic chain lifting device is positioned under the crane arm and saves right-hand end.Earlier crane arm is holded up during work, utilized the rack-and-gear lifting device to regulate joint height on the crane arm then, utilize the hydraulic chain lifting device to regulate in the crane arm, go up the joint height, at last crane arm is fixed.This light-duty lifting mode boom crane is a kind of portable jib crane, aims at the technological transformation of 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 primary equipment below 1 ton.But this light-duty lifting mode boom crane complex structure, hoisting capacity is difficult to accomplish more than 1 ton.

The fixed column type boom crane has the effect that portable jib crane can not replace, it has advantages such as simple in structure, easy to operate, that revolution is flexible, working space is big, hoisting capacity generally can reach 2 tons to 5 tons, be widely used in the loading and unloading work of manufacturing line, fitting line and the lathe in workshop, and the weight handling of occasion such as warehouse, harbour.The height of the revoliving arm of fixed column type boom crane is fixed, and runs into the higher or object oneself height condition with higher of lifting altitude of handling object, need solve by miscellaneous equipment is auxiliary.And under the prerequisite of not sacrificing advantages such as said structure is simple, hoisting capacity is big, the height of the revoliving arm of fixed column type boom crane also can being adjusted, prior art does not also have solution at present.

The utility model content

The purpose of this utility model provides a kind of liftable fixed column type boom crane, solves the problem that the height of the revoliving arm of present fixed column type boom crane can not be regulated.

In order to realize above purpose, the technical scheme of liftable fixed column type boom crane of the present utility model is as follows:

A kind of liftable fixed column type boom crane, comprise column, the lifting pillar stiffener that described column comprises the fixed pedestal post and lead and assemble up and down in the edge in this fixed pedestal post is provided with hydraulic actuating cylinder in the fixed pedestal post, and the hydraulic actuating cylinder top is contained between described fixed pedestal post and the lifting pillar stiffener.

Described hydraulic actuating cylinder is plunger-type cylinder.

One end and the described fixed pedestal of described hydraulic actuating cylinder are column articulated, and the other end and described lifting pillar stiffener are hinged.

This liftable fixed column type boom crane raises revoliving arm by the length of regulating column or reduces, thereby has realized the adjusting to the height of fixed column type swinging boom.Because hydraulic actuating cylinder not only can the described lifting pillar stiffener of lifting, and can be used as the load-carrying parts of hoisting crane, so do not need to arrange extra load larrying member between fixed pedestal post and the lifting pillar stiffener.The rising of lifting pillar stiffener comes lifting by hydraulic actuating cylinder, and decline can spur by hydraulic actuating cylinder, but leans on the deadweight of lifting pillar stiffener to get final product usually.

Advantages such as further, the utility model can be selected plunger-type cylinder for use, and that plunger-type cylinder has is simple in structure, forced stroke is long, plunger is only done unidirectional overhanging motion, its oppositely in the contracting motion finished by external force.The installation connection mode of hydraulic actuating cylinder adopts the two ends articulated manner, can avoid the interference between the lifting of flexible and lifting pillar stiffener of the hydraulic actuating cylinder push rod that causes because of assembly error.

Description of drawings

Fig. 1 is the structural representation of liftable fixed column type boom crane.

The specific embodiment

Below in conjunction with accompanying drawing, further set forth the utility model.

As shown in Figure 1, a kind of liftable fixed column type boom crane, comprise revoliving arm 1, lifting pillar stiffener 2, fixed pedestal post 3, the lower end of fixed pedestal post 3 is fixed on the concrete foundation by holding-down bolt, lifting pillar stiffener 2 is positioned at fixed pedestal post and guiding assembling with it along the vertical direction, and revoliving arm 1 is assemblied on the lifting pillar stiffener 2 and can turns round around lifting pillar stiffener 2.In fixed pedestal post 3 inside plunger-type cylinder 5 is installed.In other embodiments, also can adopt the energy thrust output of other form and the hydraulic actuating cylinder of straight-line displacement.Cylinder body bottom and the fixed pedestal post 3 of plunger-type cylinder 5 are hinged, and the top of plunger 4 and lifting pillar stiffener 2 are hinged.

When this liftable fixed column type boom crane need improve the height of its revoliving arm 1, the plunger 4 of plunger-type cylinder 5 was overhanging, promoted lifting pillar stiffener 2 and raise.When needs reduced the height of revoliving arm 1, plunger-type cylinder 5 stopped thrust output, by the deadweight falling of revoliving arm 1 and lifting pillar stiffener 2.In other embodiments, also can adopt double acting hydraulic cylinder, when reducing the height of revoliving arm 1, hydraulic actuating cylinder can provide extra pulling force like this.

The utility model is simple and compact for structure, can easily regulate the revoliving arm height, and does not lose advantages such as hoisting capacity that original fixed column type boom crane has is big, has made things convenient for people's production operation.
