Problems solved by technology

[0003] However, in the process of transportation, the segmental beams are usually carried by means of transport such as beam transport vehicles. When erecting on the ground, beam transport vehicles are a very good choice, but when the erection site is on waters such as the Haihe River Or when the transportation needs to cross the waters, the current beam transport vehicles will be limited and cannot play the role of transportation well

Embodiment 1

[0041] see Figure 1~6 , in an embodiment provided by the present invention, a beam transport vehicle for roll-on-roll-on-ship of segmental beams includes: a beam transport vehicle for transporting segmental beams 4; a supporting floor for supporting segmental beams 4 5. There is a stabilizing component on the support base plate 5; a slide rail mechanism for assisting the rolling of the segmental beam 4 onto the ship, the slide rail mechanism is driven by a pushing mechanism, and the slide rail mechanism is installed on the beam transport vehicle The upper surface of the support base plate 5 slides in the slide rail mechanism through the damping wheels at the bottom, and the rear end of the slide rail mechanism is provided with a fixing assembly for preventing the slipping of the damping wheels.

[0042] The girder vehicle used for roll-on-rolling of segmental beams is specially used to transfer the segmental girder 4 on the beam vehicle to the ship under special circumstances...

Embodiment 2

[0059] see Figure 5-6 In yet another embodiment provided by the present invention, the pushing mechanism includes a forward and reverse motor 32 installed above the top of the vehicle board 3, and the output end of the forward and reverse motor 32 is connected to the first rotating shaft through a coupling. 33 driving connection, the bottom end of the first rotating shaft 33 is fixed with a first bevel gear 31, and the front and back of the first bevel gear 31 are meshed with a second bevel gear 30;

[0060] A second rotating shaft 29 is fixed in the second bevel gear 30, a gear 28 corresponding to the position of the inner slide rail 20 is fixed in the second rotating shaft 29, and the bottom end of the gear 28 is equipped with a The push rod 26 in the same horizontal direction of the inner slide rail 20 is provided with a tooth pitch 27 that is continuously meshed with the gear 28; the tail end of the push rod 26 is connected with the front end of the inner slide rail 20 ....

Abstract

The invention relates to the technical field of segmental girder construction, and particularly discloses a girder transporting vehicle for segmental girder boarding through roll-roll shipment. The girder transporting vehicle comprises a girder transporting vehicle body, a supporting bottom plate, a sliding rail mechanism, and a fixing assembly, wherein the girder transporting vehicle body is usedfor transporting a segmental girder; the supporting bottom plate is user for supporting the segmental girder, and a stabilizing assembly is arranged on the supporting bottom plate; the sliding rail mechanism is used for assisting the segmental girder in boarding through rolling, the sliding rail mechanism is driven by a pushing mechanism, and the sliding rail mechanism is arranged on the upper surface of the girder transporting vehicle body; and the supporting bottom plate slides in the sliding rail mechanism through damping wheels at the bottom end, and the rear end of the sliding rail mechanism is provided with the fixing assembly used for preventing the damping wheels from slipping. The girder transporting vehicle is specially used for shifting the segmental girder on the girder transporting vehicle boarding under special conditions, avoids the defect that the girder transporting vehicle cannot pass through the water surface when a bridge is built, also avoids the problem that whenthe girder transporting vehicle is directly driven to a ship, the occupied area is too large so as to influence the erection, and has the advantages of being flexible in transportation, high in safety and convenient in shift.

Description

technical field [0001] The invention relates to the technical field of construction of segmental beams, in particular to a beam transport vehicle used for roll-on-rolling of segmental beams onto ships. Background technique [0002] Segmental beam is the abbreviation of segmental assembled beam. Segmental beam is to divide the beam body into several segments. After the prefabrication is completed and the design requirements are met, it is necessary to use transportation tools to transport the beam segments from the beam storage yard to the beam erection in the order of assembly. (directly below the bridge), the girder erection machine is used to hoist the girder segments one by one according to the number, and place them on the longitudinal steel girders with pre-camber settings, and repeat this until the construction of all segmental girders is completed. At present, most of the road bridge construction in our country is carried out by using segmental beams, which can be qui...
