specific Embodiment approach

[0078] see figure 2 , a kind of specific implementation mode that the present invention provides again on the basis of above-mentioned implementation mode is as follows:

[0079] The roller bracket 312 is also provided with a screw hole and a stud 314 matched with the screw hole. The screw hole is located above or below the fourth roller 311 . The stud 314 passes through the screw hole and abuts against the mounting bracket 313 .

[0080] When the fourth roller 311 cooperates with the side of the I-beam web, the screw hole is set under the fourth roller 311, and the length of the stud 314 is shorter than the length of the fourth roller 311, so as to avoid scratching the I-beam Upper wing plate and web; When the fourth roller 311 is matched with the side of the I-beam web, the screw hole is preferably located under the fourth roller 311, and the length of the stud 314 is longer than the fourth roller 311, which can The upper part of the I-beam is limited.

Abstract

The invention provides an automatic penetrating and pulling system and method for reinforcing I-shaped steel of a frame-structure bridge jacking line, and belongs to the technical field of automatic penetrating and pulling of the I-shaped steel. The I-shaped steel, a transverse moving device, a driving device and an inter-sleeper supporting device are transported to one side of a line to be reinforced, and the inter-sleeper supporting device is used for separating the I-shaped steel from sleepers so as to reduce friction; the transverse moving device is used for supporting I-shaped steel moving transversely, and the driving device is used for driving the I-shaped steel on the transverse moving device to move transversely. According to the frame structure bridge jacking line reinforcing I-shaped steel automatic penetrating and pulling system, transverse movement of the I-shaped steel can be achieved without manual work through the transverse moving device, the driving device and the inter-sleeper supports, and therefore the labor intensity and the danger coefficient can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic threading and pulling of I-beams, and more specifically relates to a system and method for automatic threading and pulling of I-beams for reinforcing the jacking lines of frame bridges. Background technique [0002] Before the jacking project of the bridge, the rails on the bridge deck need to be reinforced to ensure that the trains can pass normally during the construction process. At present, the reinforcement is basically reinforced by I-beams. The movement of the I-beams perpendicular to the rails is called lateral movement. The movement of the I-beam parallel to the rails is called longitudinal movement. Since the train needs to run normally during the construction process, and there are more than 10,000 volts of high-voltage electricity on both sides of the roadbed, which limits the use of large cranes and other equipment, the horizontal and vertical movement of the I-beam can only be real...
