Abstract
The utility model discloses a main grider calibration reinforcement butting device for a road bridge erection machine and belongs to the field of construction machinery calibration reinforcement butting devices. The main grider calibration reinforcement butting device for the road bridge erection machine comprises a female head connection end (A) and a male head connection end (B). The female head connection end (A) comprises U-steel (1), a female head inner adhesive flitch (2), a female outer adhesive flitch (3) and a female head outer adhesive stiffening flitch (4). The male connection end (B) comprises a pin flitch (5), a male outer adhesive flitch (6) and a male inner adhesive flitch (7). The main grider calibration reinforcement butting device for the road bridge erection machine has the advantages of quickly enabling main griders of bridge erection machine to be quickly connected with each other, effectively avoiding drop and looseness, ensuring that each connection part evenly bears force, being convenient to assemble and disassemble, simple in structure, high in intensity, fast and accurate to assemble and affordable.
Description
Technical field
The utility model relates to a kind of Bridge Erector, and specifically docking facilities is reinforced in the calibration of a kind of girder of highway bridging machine, belongs to the engineering machinery calibration and reinforces the docking facilities field.
Background technology
Highway bridging machine is as one of main special equipments of bridge construction such as high-speed railway, highway, and this equipment is large, and the magnitude of value is high, and safety requirements is very high.The agent structure of present common Bridge Erector mainly is comprised of girder, front support mechanism, rear support mechanism, medial support mechanisms, auxiliary support mechanism.During bridge formation, girder is as main bearing member, and across between two bridge piers, overhead traveling crane lifts by crane prefabricated Box Girder Bridge in the girder upper surface by front support mechanism and medial support mechanisms.In the via hole operating mode, because front end stretches out longlyer, girder will bear larger moment of flexure, and the safety of girder is determining the safety in utilization of Bridge Erector.Each internode type of attachment of existing girder mainly contains Chinese character pin-shaped pin joint and is connected with bolt.In these two kinds of connected modes: Chinese character pin-shaped pin joint mode, to install rapidly, dismounting is convenient, but stressed too concentrated, has caused bore deformation and causes girder bending-down to increase; Bolt connects reasonable stress, but uses too complexity, and cost is higher.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of girder calibration of highway bridging machine to reinforce docking facilities, and crane ' s major girder is connected fast, makes whole crane ' s major girder stressed good, has both effectively prevented from coming off, and can install again rapidly accurately.
To achieve these goals, the technical solution adopted in the utility model is: docking facilities is reinforced in a kind of girder calibration of highway bridging machine, comprises female link and male link, and the female link is by channel-section steel, pasting board in the female, the outer pasting board of female and the outer reinforcing plate of female form; The male link is by pin plate, and pasting board forms in the outer pasting board of male and the male; Female link and male link are respectively equipped with pin shaft hole; The outer pasting board of pasting board and female is welded on respectively on the channel-section steel in the female, and the outer reinforcing plate of female is welded on the outer pasting board of female, then two channel-section steel make-up welding; Pasting board is welded on the channel-section steel in the male, pin plate and channel-section steel welding, the outer pasting board of male and channel-section steel welding, then two channel-section steel make-up welding.
Further, female link and male link are symmetrical structure, cooperate bearing pin to use.
The beneficial effects of the utility model are: the male link is inserted in the female link, join the lead plug axis hole, then bearing pin is inserted male link and female link are closely linked.Reinforce docking facilities by this calibration, can crane ' s major girder be linked together, effectively play anticreep, locking effect, guarantee that each connector is stressed evenly, easy accessibility, have simple in structure, intensity is high, install quick and precisely, economic and practical characteristics.

Among the figure: A, female link, B, male link, 1, channel-section steel, 2, pasting board in the female, 3, the outer pasting board of female, 4, the outer reinforcing plate of female, 5, pin plate, 6, the outer pasting board of male, 7, pasting board in the male.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, docking facilities is reinforced in the girder of the utility model highway bridging machine calibration, comprises female link A and male link B, and female link A is by channel-section steel 1, pasting board 2 in the female, and the outer reinforcing plate 4 of the outer pasting board 3 of female and female forms; Male link B is by pin plate 5, and pasting board 7 forms in the outer pasting board 6 of male and the male; Female link A and male link B are respectively equipped with pin shaft hole; The outer pasting board 3 of pasting board 2 and female is welded on respectively on the channel-section steel 1 in the female, and the outer reinforcing plate 4 of female is welded on the outer pasting board 3 of female, then two channel-section steel 1 make-up welding; Pasting board 7 is welded on the channel-section steel 1 in the male, pin plate 5 and channel-section steel 1 welding, the outer pasting board 6 of male and channel-section steel 1 welding, then two channel-section steel 1 make-up welding; Female link A and male link B are symmetrical structure, cooperate bearing pin to use.
During use: male link B inserts female link A, then fixes with bearing pin, and the beam joint is fixed together.Pasting board 2 in the female, the outer pasting board 3 of female and the outer reinforcing plate 4 of female have been strengthened female junction intensity, and junction stressed uniformly can distribute simultaneously; Pasting board 7 has been strengthened public junction intensity in the outer pasting board 6 of male and the male, and has shared the stressed of pin plate 5; Realized that each joint of girder quick and precisely links together, and junction intensity can be strengthened, distribution of force is even.
