Description
Technical field
The present invention relates to a kind of component of portal frame, more particularly to a kind of height-adjustable gantry pillar.
Background technology
Portal frame（Mobile lifting small arc shaped frame）It is in, semiworks（Company）Daily production needs haulage equipment, storehouse
Into shipment, jumbo and the needs of transport of materials, the novel small-sized hoisting portal frame developed are repaired in lifting in storehouse.It is suitable for
Manufacture mould, Automobile Service factory, mine, civil construction building site and need lifting occasion.Common doubles as material in construction
Transport and the use up and down of construction personnel, realize hoisting machinery.Manpower can be reduced, reduces production and operation cost, improves work
Efficiency.Gantry crane can simply be split as several parts easily transported, and can be very in the place that another is used
Assemble up soon, this feature is all helpful in many occasions.Portal frame is mainly made of crossbeam, column, diagonal brace and base,
Each component is connected by screw during installation.Existing column uses level altitude more, this is resulted in deposits in actual use
In inconvenience.Since each construction site height is different, required gantry height is also not quite similar.The column of traditional level altitude
Obviously use demand can not be met, meanwhile, the column of market also nonresident portion adjustment height.Such height-adjustable column, its
Structure uses double-layer square steel-tube construction, and outer layer square tube is connected with base, and internal layer square tube is connected with crossbeam, inside, on outer tube wall
Punch several, it is necessary to during upper adjusting height, internal layer square tube can be raised, be inserted into screw after the completion of to be adjusted in hole, and use screw
Fastening, it is achieved thereby that portal frame is height-adjustable.There are following defect for the column of said structure：1. internal layer square tube and outer layer
Square tube is connected through a screw thread, in use for some time, the easy stress deformation of screw of junction, and then influence to cause positioning high
The deviation of degree；2. the quantity of punching and the precision of punching all easily impact the mounting stability of equipment；3. column
, it is necessary to artificially go to adjust, operating process is cumbersome for the adjustment of height, particularly inconvenient especially when required hoisting depth is higher.
The content of the invention
In view of the above-mentioned state of the art, the technical problems to be solved by the invention are to provide a kind of easy to adjust,
And the gantry pillar that degree of regulation is high.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of height-adjustable gantry pillar,
Including column body, the column body includes outer layer square tube and is socketed on the internal layer square tube of the outer layer square tube, the column
The screw through the column body is equipped with body, screw fixed seat is equipped with the outer layer square tube bottom, in the internal layer
Square tube bottom is equipped with is equipped with driving device, the driving dress with the relatively-stationary baffle of feed screw nut, the outer layer square tube side
Put front end and be equipped with the shaft vertical with screw, the shaft passes through Bevel Gear Transmission with screw.
Further, the driving device includes manual driving device and Vidacare corp.
Further, the manual driving device includes the crank being connected with shaft.
Further, the electric device includes motor and retarder, and the shaft is equipped with screw thread, the spiral shell of the shaft
Line is engaged with the gear of retarder forms worm gear mechanism.
Further, the internal layer square tube upper end is equipped with postive stop baffle.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention uses lifting gear of the screw as column, transports
Row is steady, and hoisting depth is accurate；Screw is high by Bevel Gear Transmission, stable drive, bearing capacity with driving device；Wherein drive
Mode be divided into again it is manual and electronic, in the case of energization using motor drive, it is convenient and efficient；When under powering-off state, hand can be used
Dynamic driving, so as to meet different use conditions well.
Brief description of the drawings
Fig. 1 is a kind of overall structure diagram of height-adjustable gantry pillar of the present invention；
Fig. 2 is a kind of structure diagram of the hiding outer layer square tube of height-adjustable gantry pillar of the present invention.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, to the skill embodiment in the embodiment of the present invention, rather than all
