Problems solved by technology

However, in this kind of over-span operation, the outriggers of the bridge erecting machine need to be erected and disassembled multiple times and their positions changed. Therefore, for the huge bridge erecting machine, the operation difficulty is virtually increased and the danger is increased. factor, while also extending the operating time

Embodiment 1

[0030] according to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a spanning conversion outrigger for the longitudinal movement of a walking bridge erecting machine mainly includes: a fuselage 1, the fuselage 1 is composed of a pair of beams arranged horizontally and parallel to each other, the machine The top and bottom of the body 1 are respectively provided with an upper slide rail 3 and a lower slide rail 4 along the length direction; the bottoms of the two ends of the fuselage 1 are respectively provided with a front leg and a rear leg; the first leg 7, the second leg 8. The first leg 7 and the second leg 8 are set in the same structure, and are respectively provided with a support frame 9, and the support frame 9 is a rectangular frame structure arranged horizontally; the length of the support frame 9 The axis direction is perpendicular to the extension direction of the fuselage 1, a...

Embodiment 2

[0040] The rotating mechanism 15 is composed of an upper component and a lower component, the upper component is connected with the moving pulley block of the crane 14, and is suspended on the crown block 13, the upper component is provided with a rotating motor, and the rotating The output shaft of the motor extends vertically downward; the bottom of the lower member is provided with a hook, and the top of the lower member is rigidly connected with the output shaft of the rotary motor; the top of the support frame 9 is connected with the Hanging loops for hooks.

[0041] In the above setting, the rotating mechanism 15 is used as the hook of the crane 14, and the suspended object is adjusted horizontally during the hoisting operation through the operation of the rotating motor, and at the same time, the hook of the lower component and the hanging ring on the top of the support frame 9 are occupied. , in the fixing and uncoupling link, workers are required to carry out assembly...

Embodiment 3

[0043] The control device includes a hydraulic system. The hydraulic system includes a hydraulic pump, a first control valve, and a second control valve. The input ends of the first control valve and the second control valve are connected to the hydraulic pump through a high-pressure oil pipe. The output end communicates, the control end of the first control valve communicates with the oil pipe interface of the support cylinder 10, and the output end of the second control valve communicates with the oil pipe interface of the longitudinal traveling oil cylinder 11 through a high-pressure oil pipe.

[0044] In the above setting, the first control valve controls each support cylinder 10 of the first leg 7 and the second leg 8, which is used for fine-tuning the lifting and load transfer of the whole bridge erecting machine, and the second control valve controls the longitudinal travel. The oil cylinder 11 is used to move the first outrigger 7 and the second outrigger 8 on the lower...

Abstract

The present invention relates to the technical field of bridge-erecting machines, in particular to a span-type conversion outrigger for the longitudinal movement of a walking-type bridge-erecting machine, which mainly includes: a fuselage, the fuselage is composed of a pair of beams arranged horizontally and parallel to each other Body structure, the top and bottom of the fuselage are respectively provided with an upper slide rail and a lower slide rail along the length direction; the first leg, the second leg, the first leg and the second leg are of the same structure set, and are provided with support frames respectively, and the bottom of each support frame is connected with a downwardly telescopic support oil cylinder; a longitudinal travel oil cylinder, the longitudinal travel oil cylinder is arranged parallel to the extension direction of the fuselage; a crane, the The crown block is used for suspension and torsion operations. The mechanism adopts the leap-forward conversion of outriggers, and cooperates with the innovative technology of walking-type longitudinal movement, directly spans the first or second outrigger to the cover beam of the previous span, and then realizes the bridge erection machine through the longitudinal travel oil cylinder and the lower rail. vertical movement task.

Description

technical field [0001] The invention relates to the technical field of bridge erecting machines, in particular to a span-type conversion outrigger used for the longitudinal movement of a walking bridge erecting machine. Background technique [0002] Usually, during the longitudinal movement of the bridge erecting machine, firstly, the front and rear lifting cranes move to the top of the middle top high outrigger, and the front outrigger, middle top high outrigger, and rear top high outrigger lift the main girder; after that , after hoisting the crane, the bracket goes to the vicinity of the middle top high outrigger, and then puts away the front outrigger, middle and rear top high outriggers, so that the middle and rear brackets are in a stressed state, after that, lift the front and rear The crane travels to the rear rear high leg, and starts the middle and rear bracket rollers to push the main beam forward, so that the rear high leg moves to the vicinity of the rear bracke...
