Double-beam bridge erection machine

Abstract

The invention discloses a double-beam bridge erection machine, which comprises a traveling frame and beam rails symmetrically arranged on the left and right sides of the traveling frame and extendingforward and backward, the beam rail is provided with a rail groove whose opening faces the traveling frame and extends forward and backward, A rack is arranged on the bottom wall of the rail groove, Arotary rack is rotatably installed in the walking rack, A hydraulic press is fixedly installed on the top wall of the rotating frame, a multi-stage hydraulic rod extending downward is fixedly installed in the rotating frame, An upper part of that multi-stage hydraulic rod is communicate with the interior of the hydraulic press, A low end of that multi-stage hydraulic rod is fixedly installed witha fixing plate, A light rod is fixedly instal at that lower end of the fix plate, a long strip is fixedly installed at the lower end of the light rod, a slide plate is slidably installed on the lightrod between the fix plate and the long strip, and a first pressing spring wound on the light rod is arranged between the slide plate and the fixing plate.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a double beam bridge erecting machine. Background technique [0002] With the continuous development of transportation, high-speed rail and high-speed are constantly developing. In bridge construction, the prefabricated bridge body is often placed on the prefabricated bridge pier by using a bridge erecting machine. When lifting the prefabricated bridge body, often Use the hook to hook the prefabricated bridge body into the long trough, and since the hook is often fixed with the wire rope, it is difficult to insert the hook into the long trough, and it is often necessary to manually insert the bridge into the long trough. The hook is inserted into the long slot, and when the bridge body is lifted, it is easily affected by the cross wind, which greatly increases the potential safety hazard, and the bridge erecting machine is often placed in the transportation process due to its l...

[0002] With the continuous development of transportation, high-speed rail and high-speed are constantly developing. In bridge construction, the prefabricated bridge body is often placed on the prefabricated bridge pier by using a bridge erecting machine. When lifting the prefabricated bridge body, often Use the hook to hook the prefabricated bridge body into the long trough, and since the hook is often fixed with the wire rope, it is difficult to insert the hook into the long trough, and it is often necessary to manually insert the bridge into the long trough. The hook is inserted into the long slot, and when the bridge body is lifted, it is easily affected by the cross wind, which greatly increases the potential safety hazard, and the bridge erecting machine is often placed in the transportation process due to its large volume. It needs to be disassembled, but it needs to be assembled during construction. Due to the large number of parts, the assembly is more troublesome and the assembly time is longer
