The specific embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Shown in Fig. 1-2, a kind of electronic construction lifting crane span structure is characterized in that: comprise base 1, be installed with column 2 on the base 1, erection bridge crossbeam 3 on the column 2, crane span structure crossbeam 3 are provided with motor driver 31, safety guide rail 32 and foot plank 33; Described base 1 is provided with 11, five supporting legs 11 of five supporting legs has four to be positioned over around the base 1, and one is placed on base 1 center; On the described base 1 four wheels 12 is housed also; Also has a yielding rubber bumper 13 on the described base 1.
Before using the electric crane span structure, must be earlier by technical professional's scheme of designing and constructing, adjust load and each position stressing conditions of climbing frame, load and stressing conditions during checking computations are constructed.When building the electric up-down crane span structure, should organize special construction team and service technician, build in strict accordance with working specification and arrangement and method for construction.The extreme length that the electric up-down crane span structure uses twin columns to reach is 30.10m.The most often when only using single column reach 9.8 meters, certainly when do not need also can be by not installing some member when so long.The maximum load capacity of electronic crane span structure more its length is relevant, at installation phase, must think about required length of crane span structure and cooresponding with it bearing capacity.
Using its bearing area of electric up-down crane span structure must be the plane, as skyscraper podium is arranged, and can set up on the podium top board, but must do reinforcement measure.First segment column and motor driver just are installed on the base.Must carefully regulate the adjustable support leg at center when laying base, main stress point is concentrated on the centre leg, main its stabilization of all the other four supporting legs.Erection bridge crossbeam on column must begin to install electronic crane span structure at bottommost then, and approximately overhead 1.8m when crossbeam is installed, wants symmetry installation simultaneously in the column both sides, prevents that column from tilting.After treating that the crane span structure crossbeam installs, erection bridge stair on base can be spread foot plank then on the crane span structure crossbeam, and guardrail is installed by edge.Face width of electronic construction crane span structure itself is 1.3m, if the crane span structure width can consider to use telescopic girder on the crane span structure crossbeam to increase its width, the maximum tensible 0.95m of telescopic girder inadequately.If because of there being protrusion to make the crane span structure inboard when the wall distance surpasses 300mm on the wall, guardrail must be installed in the crane span structure inboard.Guardrail is inserted in the hole of telescopic girder, tightens with bolt.Can install the upper strata column additional then on the first segment column, column does not have the interval 6 meters the attached wall point must be arranged, and by attached wall frame and expansion bolt column is connected together with external wall.
Must note the symmetry installation in the electric up-down crane span structure installation process, can switch on behind the support body after to be installed the finishing and do trail run, check whether each parts of crane span structure and electric switch be normal.Do in strict accordance with the various operating sequences that this handbook requires.The electric up-down crane span structure can only be used to promote workmen and a small amount of material, can not be with using it for anything else.The electric up-down crane span structure has only under the on even keel and could use.Have only personnel could operate electronic crane span structure through training.Electronic construction lifting crane span structure is by base, column, and the crane span structure crossbeam, motor driver, safety guide rail, foot plank, crane span structure stair are formed.
Be a kind of lifting machinery by gear, rack driven, the very electric and machine security system of failure-free is arranged, it can raise voluntarily along with the rising of building, and crane span structure can extend or shorten as required.Electronic construction lifting crane span structure install, need not prefabricated basis when using, only need remove part column and attached wall when mobile, change operating location easily by the wheel of bottom.
The chassis that each crane span structure base all has a lead frame to make is used to disperse column to pass the load of coming by five supporting legs on the chassis.Five supporting legs have four to be positioned over around the crane span structure base, and one is placed on crane span structure base center, can make total more stable like this.Wherein Wai Ce four extensible supporting legs should be opened under the situation that single-column uses as far as possible, and the stability of the electronic crane span structure of single-column can be better like this.Four wheels also is housed on the base, can under the situation that need not break the construction crane span structure fully, moves on-site.In addition, on the crane span structure base, also have a yielding rubber bumper, in the time of can reducing the construction crane span structure and descend to the impact of base.
Column is the triangle lattice that is welded by square steel tube, tooth bar, reinforcing bar etc., and the height of standard knot is 1.5m, and vertical direction reaches specified altitude assignment by the high strength bolt connection of M20 * 80.Column is divided into standard column and spacing column, and spacing column is mainly used in bottommost and top.When the micro-switch on the actuator touches limiting stopper on the spacing column, stop automatically, prevent actuator collision base or run off column and cause danger.
The crane span structure crossbeam is the basis of forming construction lifting crane span structure driving surface, and it is the triangle lattice frame that is welded by three square steel tubes.Form by 1.5m and two kinds of different sizes of 1.0m, connect by bearing pin between them and form different length.
Motor driver is the engine installation of construction lifting crane span structure, can do vertical motion along column by the rotation of two electrical motors.Electrical motor has from brake gear, can be stuck on column actuator when outage.Electrical motor moves on the tooth bar of column by wheel word.
In addition, independently centrifugal anti-fall device has been installed all on each actuator, can under unexpected situation, have been embraced column when electronic crane span structure quickens to descend, prevented that electronic crane span structure from continuing down to fall.Each actuator is all led by 15 track adjusting wheels, steadily moves along column.Various sensors have been installed, auto-stop under dangerous situation on the actuator.Guardrail is the setting framework of welding, and sleeve is on the crane span structure crossbeam.Guardrail height 1.2m, the bottom is provided with foot guard plate.Length is divided two kinds, and is corresponding with the length of crane span structure crossbeam.
Foot plank is the shaping tool formula foot plank that punching sheet steel and steel frame are welded, and installs rapid, simple, firm.
The crane span structure stair are the tool-type stair that are welded, and are installed on the electric up-down crane span structure base, are the walking passages of electronic crane span structure up and down.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
