Abstract
The utility model discloses an improvement on the basis of the original gantry crane, which is characterized in that the supply unit of the crane is composed of a main cable reel and an auxiliary cable reel. One root complete flexible cable is for winding on the main cable reel and the auxiliary cable reel of the supply unit [6] in a certain method; one end of the cable is directly led to a control office, and the other end is connected with the ground power source.
Description
The utility model relates to a kind of rail mounted gauntry crane.
Gauntry crane in the prior art is made up of door frame, control cabin, electric block, electric supply installation and cart track, and the mode that its electric supply installation adopts slidnig track type or electric brush slip ring to add the cable reel is introduced foreign current.Its shortcoming be this mode meet the rainy day or when making moist crawler shoe or the resistance of electric brush slip ring increase suddenly, automatically controlled part automatic trip usually appears, repaired 1～2 hour consuming time at every turn, influence is produced.
The purpose of this utility model is to provide a kind of direct supply mechanism, even this mechanism works under the environment of humidity, also can not increase resistance.
The utility model is the improvement on the basis of original gauntry crane, and it is made up of door frame 1, control cabin 4, electric block 2, electric supply installation 6, big Car Track 5 and hydraulic pressure load limiter 3.During work, the cart on the door frame is walked in that big Car Track is up, and sling weight and control cabin of electric block walked on the track of door frame girder together, and weight is placed on any old place in the place.During large vehicle walking, cable is emitted or rolled to the main drum of electric supply installation; Load limiter then plays the effect that prevents to lift by crane overload.
Describe principle of work of the present utility model in detail below by embodiment.
Fig. 1 is the structural representation of gauntry crane.
Fig. 2 is the left view of Fig. 1.
Door frame 1 is installed on the big Car Track 5, and control cabin 4 and electric block 2 are installed on the girder of door frame 1, and hydraulic pressure load limiter 3 is housed on electric block 2.Electric supply installation 6 is installed in position higher on the door frame, and apart from 6～12 meters of rail levels, it is made up of diameter bigger main drum and the less loose drum of diameter, and major and minor reel is coaxial to connect firmly, and can rotate synchronously.A complete flexible cable is wrapped in respectively on the major and minor reel, earlier cable by certain around to around full main drum, cable continues by certain around to around full loose drum near an end of loose drum, cable on major and minor reel around to can be identical, also can be opposite, the supply cable that twines on the main drum links to each other with ground power supply, and the cable that twines on the loose drum directly links to each other with the electric power distribution cabinet of control cabin 4.The difference in size of major and minor reel should make the cable that twines on the main drum all decontrol or all twine when full, and the cable on the loose drum is finished one just and twined the cycle full, that decontrol.Ground power supply is installed in the center of crane stroke, cart was positioned at the total travel mid point when cable was installed, major and minor reel twines full cable simultaneously, loose drum twines the number of turns of cable and the ratio of the calculating number of turns that main drum twines cable is 0.5～0.9, wherein best ratio is 0.6, the calculating number of turns of main drum equal the cart stroke half cable length around the number of turns of main drum.When hoisting crane was worked, along with the operation of cart, reel is rotation automatically under the effect of coiling moments such as cable deadweight, cable stretch and weight or motor, emits or regain supply cable.Meanwhile, during cable on the loose drum and emit, be suspended in the space of roll device bottom; The time and regain, be wrapped on the loose drum.When cart was walked to the stroke center, major and minor reel all twined full; Cart walk to stroke 1/4th or 3/4ths apart from the time, main drum bleeds off half cable, loose drum has been put, beginning is oppositely twined; When cart is walked to the stroke termination, main drum emptying, loose drum twines full again.When the cart stroke requires not grow, loose drum can be designed to only do unidirectional winding, make its cycle of operations consistent with main drum, can prolong the service life of cable.
Electric supply installation after the improvement is a simple cable winding mechanism, the cable that twines on the loose drum plays cushioning effect, a cable can directly be received power distribution cabinet from power supply, has avoided being exposed to airborne terminal, thereby has eliminated the impact of humid environment to circuit. Because in a stroke, the cable on the loose drum can rewind several times, so that this mechanism is simply compact, obtain simultaneously long stroke.
From the above, the utility model is loaded onto the electric supply installation after the improvement, and crane is improved the adaptive capacity of working environment.
