Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] In order to achieve the above object, the technical solution adopted in the present invention is to configure a set of "load-bearing self-balancing system" for the beam transport vehicle. The principle is that when the crown crane lifts the concrete beam, the rearward tilting moment of the alighting system caused by the huge pressure on the rear load-bearing horizontal pad beam of the frame main beam of the alighting system is transmitted through the load-bearing rear outriggers of the alighting system. The anti-reversing moment (that is, the stabilizing moment) generated by the load-bearing self-balancing system is used to offset and have a safety surplus, without the need to achieve i...

The invention discloses a bridge erecting unit capable of load-bearing self-balancing and a bridge erecting method using the same. The bridge erecting unit includes a boarding system and a disembarking system, and several pairs of cylinder-type outriggers installed on the disembarking system vehicle. The rear side of the load-bearing transverse pad beam at the rear of the main beam of the frame; the control device is used to control the cylinder pressure and stroke of several pairs of cylinder-type outriggers. The present invention adopts the configuration of three pairs of cylinder-type outriggers, and by controlling the pressure of the cylinder-type outriggers, the anti-reversing moment generated by it is greater than or equal to the load-bearing rear outriggers of the boarding system and transmitted to the rear load-bearing horizontal pad beam of the dismounting system. The moment of tilting backwards of the alighting system caused by the pressure ensures that the alighting system can maintain its load-bearing balance by itself during the whole process of beam erection, and ensures the longitudinal stability of the alighting system. It is easy to operate, safe and Advantages of economy and high efficiency.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a bridge erecting unit capable of load-bearing self-balancing and a bridge erecting method using the same. Background technique [0002] The bridging unit is mainly composed of a boarding system and a disembarking system. The boarding system is mainly composed of the main structure of the bridge crane and the overhead crane, and the disembarking system is also served by a tire-type beam transporting vehicle. The boarding and disembarking systems are used in conjunction with each other. The steps for erecting the first hole beam of a bridge are as follows: [0003] Step 1, see Picture 1-1 , the loading system of the bridge crane is in the state of rear cantilever beam feeding, the rear-end walking outriggers are tilted backwards, the rear outriggers are retracted after bearing the load, and the alighting system (that is, the tire-type beam transporter) transports t...
