Abstract

The utility model discloses an electric standard section introduction device of a tower crane. The electric standard section introduction device comprises a cross beam, an introduction beam, an introduction trolley and a special standard section lifting appliance, wherein the introduction beam is mounted on the cross beam; the introduction trolley is mounted on the introduction beam; the special standard section lifting appliance is arranged on the introduction trolley; the introduction trolley is an electric introduction trolley; a motor and a speed reducer are arranged on the introduction trolley. When a standard section is lifted by the tower crane, the standard section is hung on the electric introduction trolley by the special standard section lifting appliance, the electric introduction trolley is controlled by a tower erecting worker through an operating box and can move back and forth in the introduction beam, and the standard section is introduced into a lifting jacket frame. According to the electric standard section introduction device, the standard section is introduced into the jacket frame by electric energy, so that the problems of a great number of workers and long consumed time in a manual introduction process are solved; as the standard section does not need to be directly pushed by manpower, the safety of a lifting process is improved.

Description

The electronic imported unit of tower machine standard knot

One, technical field

The utility model relates to a kind of tower machine standard knot imported unit, is in the jacking of tower machine, unloading process, to utilize electric energy to introduce or release the electronic imported unit of tower machine standard knot.

Two, background technology

Tower crane mostly is jack up, is the rising along with building, adopts jacking apparatus, and standard knot is added one by one, reaches the synchronous object raising of tower crane.At present, the jacking of most of tower machine, standard knot has two kinds of introduction of method.(1) adopt lower introduction, introduction beam is arranged on the bottom of tower machine standard knot, the standard knot that will add is placed on and is introduced on dolly, and then be lifted on introduction beam, introducing dolly bottom has wheel, can move along introducing beam, and operator stands on platform, use Manual-pushing standard knot, sent in tower body.(2) go up introduction of method, introduce beam be suspended on revolution undersetting below, the standard knot top that add is installed to introduction dolly, then introduction dolly is lifted on introduction beam, now standard knot hangs.Operator stands in tower body and catches hold of standard knot with hook, is drawn in tower body.No matter above which kind of mode, all needs to complete by manpower the standard knot work of introducing.

Because tower machine structure needs, standard knot specification is different, and general tower machine standard knot deadweight is many 2 tons of left and right, and what the standard knot of Large Towers machine had reaches tens tons, needs manpower more when standard knot pushes stock, causes introducing process more difficult.Adopt above-mentioned introduction of method, also exist certain security risk.

Three, summary of the invention

In order to solve the problem of introducing standard knot difficulty, the utility model provides a kind of tower machine standard knot electronic imported unit, this device adopts electronic introduction dolly that standard knot is introduced or drawn stock, can save manpower and can improve introduction speed again, has greatly improved the safety of jacking process.

The technical solution adopted in the utility model is: the electronic imported unit of tower machine standard knot, comprise rood beam, introduce beam, introduce dolly and standard knot special hanger, introducing beam is installed on rood beam, introducing dolly is placed on introduction beam, on introduction dolly, there is standard knot special hanger, introduction dolly of the present utility model is electronic introduction dolly, introduce on dolly with motor and retarder, when tower machine lifting guide support adding, use special hanger that standard knot is hung on electronic introduction dolly, vertical tower librarian use effector is controlled electronic introduction dolly, electronic introduction dolly can be walked front and back in introducing beam, standard knot is introduced into jacking stock inner.

The beneficial effects of the utility model are, can utilize electric energy that standard knot is introduced into stock inside, have solved many, the consuming time many problems of the required personnel of artificial introduction.Because nobody directly promotes standard knot, improved the safety of jacking process.

Five, the specific embodiment

The electronic imported unit of tower machine standard knot comprises rood beam 1, introduces beam 2, introduces dolly 3 and standard knot special hanger 4.Introduce beam 2 and be divided into front introduction beam 2-1 and rear introduction beam 2-2, rear introduction beam 2-2 is 2 H-girders, and centre is connected with bolt with H-girder with angle steel.The main limb of front introduction beam 2-1 is 2 H shaped steel, with steel plate, it is connected and firm welding, on main limb, is welded to connect otic placode, and front end is connected with rear introduction beam 2-2 otic placode.In the middle of rear introduction beam 2-2, otic placode is connected with arm-tie 5, and arm-tie 5 is connected with pull bar 6 again, and the upper end of pull bar 6 is fixed on rood beam 1.Pull bar 6 band turnbuckles, make pull bar 6 length have certain regulated quantity, to guarantee that pull bar 6 can be held, introduce beam 4.Introduce dolly 3 and formed by dolly vehicle body 7, positive transport wheel 9 and passive walking wheel 8, motor and retarder 10 are installed on vehicle body 7.Positive transport wheel 9 and the passive walking wheel 8 of introducing dolly 3 are limited on the track of introducing beam 3, motor and retarder 10 are fixed on to be introduced on dolly 3, on introduction beam 2, be provided with cable drum 12, in slip ring system in the cable 11 access cable drums 12 of drawing from electric cabinet 13, from the access of slip ring system other end outgoing cable, introduce the motor of dolly.Emit cable: after pressing effector 14 and switching on power, electric motor starting, introduces dolly along rail moving, and cable is pulled out from reel; Retracting cable, when introduction dolly moves back, due to the effect of the volute spiral spring in cable drum, drives reel retracting cable.The circuit of the electronic imported unit of tower machine standard knot is to motor M 801, to be powered through circuit breaker Q F801 and AC contactor KM800, AC contactor KM801 main contact by three-phase alternating-current supply, also through rectifying circuit, to drg YB801, powers simultaneously; TC800 level output 48VAC of voltage transformer connects AC contactor KM800 coil through circuit breaker Q F802 and button S807, forward switch S 800, AC contactor KM801 normally closed contact respectively, through circuit breaker Q F802 and button S807, reversal switch S801, AC contactor KM800 normally closed contact, connects AC contactor KM801 coil.
