Abstract
The utility model discloses a wind resistant device of a cable loading crane, which comprises an upper screw and a lower screw, wherein the upper screw with a hinged support base is used for being connected with a traveling support of a cable loading crane traveling system, the lower screw with a hinged support base is used for being connected with the tail portion of an inserting section of a primary truss, and the upper screw has the same structure as the lower screw. A threaded sleeve is rotatably connected between the upper screw and the lower screw to form a length adjusting mechanism which ensures that the central face of the primary truss is in the vertical plane. The wind resistant device of the cable loading crane enables the primary truss arranged on the cable loading crane to be in a horizontal state and in rigid connection with the traveling system fixed on a main cable of a suspension bridge, thereby greatly improving the rigidity of the whole crane to resist strong wind.
Description
Technical field
The utility model relates to the specialized equipment deck unit erection gantry accessory device of suspension bridge construction, is used to strengthen the high-altitude wind loading rating of equipment.
Background technology
Deck unit erection gantry is an employed Special Hoisting Equipment when adopting vertical-lift method lifting steel case beam in the suspension bridge construction, and China makes the best use of the advantages and all used deck unit erection gantry in the large-scale suspension bridge processes such as Jiang Daqiao, Transbay Bridge, Shantou and set up operation building Humen Bridge, profit.Particularly along with expanding economy, this typhoon hotspot also needs to build the development of large-span suspension bridge with the traffic of promotion in the riverine and coastal area.Because suspension bridge sets up the cycle of steel case beam and wants some months usually, inevitably can be subjected to the attack of high wind in this course.Be supported on adverse effects such as vibration that deck unit erection gantry on the main rope of suspension bridge more needs wind-proof device to resist high wind to cause, skew.The existing deck unit erection gantry that occurred of China phenomenons such as upset, vibration, bearing pin fracture, Deformation Member is reversed can occur owing to being connected high wind loading cross sill by bearing pin between crossbeam and end carriage, therefore, designing a kind of simple and reliable deck unit erection gantry wind-proof device is necessary with the wind loading rating that improves deck unit erection gantry.
Summary of the invention
In view of the above shortcoming of prior art, that the purpose of this utility model is to provide is simple in structure, good reliability, the wind-proof device that uses on deck unit erection gantry that wind loading rating is strong.
The purpose of this utility model is to realize by following means.
The deck unit erection gantry wind-proof device, comprise being used for the last screw rod of the joining band hinged-support of the walker of deck unit erection gantry running gear and having the following screw rod that is used for the band hinged-support that connects with the insertion segment trailer of main couple, but screw thread bush turn ground is connected the described length adjustment mechanism of longitudinal plane of symmetry on vertical plane of going up formation assurance main couple between screw rod and the following screw rod with spline structure.
During actual the use, be installed on the walker of deck unit erection gantry running gear and the insertion segment trailer of main couple by bearing pin screw rod respectively.Length by regulating wind-proof device with the longitudinal plane of symmetry that guarantees main couple on vertical plane, and with the running gear wind resistance that is fixed on the main rope of suspension bridge, to improve the wind loading rating of deck unit erection gantry.
The utility model deck unit erection gantry wind-proof device have a following advantage.
1, simple in structure, easy to operate: the utility model deck unit erection gantry wind-proof device comprises that two band screw rods of hinged-supports and one are with externally threaded sleeve to form, when not using, only need pull down bearing pin and just can take off wind-proof device, during the length that needs to regulate wind-proof device as long as pass through the externally threaded sleeve of rotating band.
2, wind loading rating is strong: by wind-proof device with main couple on the deck unit erection gantry be in horizontality and and be fixed in and cause after running gear on the main rope of suspension bridge is rigidly connected and resist high wind, improved the rigidity of complete machine greatly.
In sum, the utlity model has advantages such as simple in structure, easy to operate, wind loading rating, can satisfy deck unit erection gantry is resisted high wind on main push-towing rope needs.
Description of drawings
Fig. 1 is the scheme drawing of the utility model installation site.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is a deck unit erection gantry wind-proof device effect scheme drawing of the present invention.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In the accompanying drawing, 1, screw rod, 4 times screw rods on the insertion segment trailer of main couple, 2 running gear walkers, 3,5 screw thread bushs, 6 hinged-supports, 7 hinged-supports.
Can find out in conjunction with Fig. 1 Fig. 2 Fig. 3, the utility model comprises the last screw rod 3 that is used for the band hinged-support 6 that connects with the walker 2 of deck unit erection gantry running gear and has the following screw rod 4 that is used for the band hinged-support 8 that connects with the insertion segment trailer 1 of main couple with spline structure, but a screw thread bush 5 turns ground is connected the described length adjustment mechanism of longitudinal plane of symmetry on vertical plane of going up formation assurance main couple between screw rod 3 and the following screw rod 4.
Under calm, weak wind environment, do not need wind-proof device to be rigidly connected.When deck unit erection gantry when hiding the typhoon process, power system, the hydraulic efficiency pressure system of complete machine quit work, after the described running gear of deck unit erection gantry is fixed on main push-towing rope, the main couple of deck unit erection gantry and running gear are except adopting adapter shaft is connected, main couple and running gear are fixed together by upper and lower hinged-support by the utility model again, the longitudinal plane of symmetry that guarantees described main couple by length adjustment mechanism is positioned on the vertical plane, and with the described walking system wind resistance that is fixed on the main rope of suspension bridge.
Claims (1)
1. deck unit erection gantry wind-proof device, it is characterized in that: comprise being used for the last screw rod (3) of the joining band hinged-support of walker (2) of deck unit erection gantry running gear and having the following screw rod (4) that is used for the band hinged-support that connects with the insertion segment trailer (1) of main couple with spline structure, a screw thread bush (5) but turn be connected the described length adjustment mechanism of longitudinal plane of symmetry on vertical plane that constitutes the assurance main couple between screw rod and the following screw rod of going up.
