Abstract
The utility model discloses an automatic gradient adjusting type portal crane which comprises a rigid landing leg and a flexible landing leg, wherein a main beam is arranged on the rigid landing leg and the flexible landing leg; a guiderail is arranged on the main beam; a longitudinal-moving truss which is capable of driving a crab on the longitudinal-moving truss to move longitudinally is arranged on the guiderail; a transverse guiderail is arranged on the longitudinal-moving truss; the crab is capable of moving transversely on the longitudinal-moving truss without the help of a running truck, so that the hoisting is convenient; a movable landing leg is arranged at the lower part of the rigid landing leg; the movable landing leg consists of a balance beam, a hydraulic oil cylinder and an outer sleeve, so that when the crane is used for constructing inclined bridge floors, the height of the movable landing leg is adjusted through the hydraulic cylinder, the main beam keeps horizontal and the stability during the equipment hoisting is improved; a balance type running truck is arranged at the lower part of the rigid landing leg and the flexible landing leg; a manual rail clamping device is arranged on the balance type running truck; the manual rail clamping device is capable of well fixing the portal crane.
Description
Technical field
The utility model belongs to bridge weight-lifting equipment technical field, specifically relates to a kind of automatic supertronic transfer crane that is applicable to bridge construction.
Background technology
Along with the needs of China economy suggestion, the developing rapidly of China Expressway, bridge construction is also more and more, and transfer crane, as the large special equipment in construction, has become indispensable key equipment in bridge on highway construction.In the process of bridge erection, need to bridge parts or other foreign material be risen on bridge floor by transfer crane, but current transfer crane in use exists several problems: when 1, transfer crane is constructed on the bridge floor tilting, because transfer crane supporting leg can not be adjusted height, cause the girder of hoisting crane to tilt, in the time of lifting, have potential safety hazard; 2, crane carriage can only laterally be walked on girder, can not longitudinally walk.
Summary of the invention
The utility model is mainly to solve the existing technical matters of above-mentioned prior art, a kind of automatic supertronic transfer crane is provided, by the setting of kinematic support leg, when hoisting crane is constructed on the bridge floor tilting, by adjusting the height of kinematic support leg, make girder maintenance level, the stability while having improved equipment hoisting; Longitudinally walk and realize transverse shifting on girder by vertical shift purlin car, longitudinally walking, convenient lifting.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: supertronic transfer crane automatically, comprise rigid leg and flexible leg, it is characterized in that, on described rigid leg and flexible leg, girder is set, on described girder, guide rail is set, on described guide rail, there is vertical shift purlin car, can drive the crane carriage being arranged on the car of vertical shift purlin longitudinally to walk, on the car of described vertical shift purlin, be provided with cross slide way, described crane carriage can be on the car of vertical shift purlin transverse walking function, do not need to realize by running truck convenient lifting.
As preferably, described rigid leg and flexible leg bottom are provided with kinematic support leg, described kinematic support leg is made up of hydraulic actuating cylinder overcoat, hydraulic actuating cylinder, total balanced seat, total equalizer and balanced seat, when hoisting crane is constructed on the bridge floor tilting, adjust the height of kinematic support leg by hydraulic actuating cylinder, make girder maintenance level, the stability while having improved equipment hoisting.
As preferably, described rigid leg and flexible leg bottom are provided with balance-type running truck, and described balance-type running truck can longitudinally be walked about on guide rail.
As preferably, on described balance-type running truck, be provided with Manual rail clamping device, described Manual rail clamping device can be by so fine transfer crane that to be fixed on guide rail.
The beneficial effect the utlity model has: 1, by the setting of kinematic support leg, when hoisting crane is constructed on the bridge floor tilting, by adjusting the height of kinematic support leg, make girder maintenance level, the stability while having improved equipment hoisting; 2, by the setting of vertical shift purlin car guide rail, make the crane carriage not only can transverse walking function, and can longitudinally walk, do not need to realize by running truck convenient lifting.Therefore, the utlity model has the features such as rational in infrastructure.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: supertronic transfer crane automatically, as depicted in figs. 1 and 2, comprise rigid leg and flexible leg, on described rigid leg and flexible leg, girder is set, on described girder, guide rail is set, on described guide rail, there is vertical shift purlin car, can drive the crane carriage being arranged on the car of vertical shift purlin longitudinally to walk, on the car of described vertical shift purlin, be provided with cross slide way, described crane carriage can be on the car of vertical shift purlin transverse walking function, do not need to realize by running truck convenient lifting.
Rigid leg and flexible leg bottom are provided with kinematic support leg, as shown in Figure 3 and Figure 4, described kinematic support leg is made up of hydraulic actuating cylinder overcoat, hydraulic actuating cylinder, total balanced seat, total equalizer and balanced seat, when hoisting crane is constructed on the bridge floor tilting, adjust the height of kinematic support leg by hydraulic actuating cylinder, make girder maintenance level, the stability while having improved equipment hoisting.
Rigid leg and flexible leg bottom are provided with balance-type running truck, and described balance-type running truck can longitudinally be walked about on guide rail.On described balance-type running truck, be provided with Manual rail clamping device, described Manual rail clamping device can be by so fine transfer crane that to be fixed on guide rail.
When work, first by balance-type running truck, transfer crane is moved to Hoisting Position, just transfer crane is so fine that to be fixed on guide rail by Manual rail clamping device; If now find girder non-level, the hydraulic actuating cylinder by kinematic support leg, by rigid leg jack-up certain altitude, makes girder and ground level, now lifts dead work and completes, and can start lifting.When lifting, crane carriage not only can specify longitudinally to walk by girder, and can be by the cross slide way on the car of vertical shift purlin, carry out transverse walking function, while having avoided common transfer crane transverse walking function, need balance-type running truck to move, cause the problem that girder can not maintenance level, facilitate lifting, reduced the dead work of lifting, improved the work efficiency of lifting.
Finally it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
