Technical field
The present invention relates to the used loop wheel machine equipment of lifting installation process such as the precast construction part of the medium-and-large-sized building of a kind of large scale civil engineering or building materials, refer in particular to the deck unit erection gantry that the precast beam sections to the large-scale suspension bridge bridge lifts.
Background technology
Deck unit erection gantry is used for the suspension bridge box girder segment more to be risen and re-mounts, as steel box girder segment or concrete box girder segment.The two root architecture main push-towing ropes that deck unit erection gantry normally relies on suspension bridge to install in advance are supporting point, adopt vertical-lift box girder segment under the main push-towing rope, and articulate with hoist cable on the main push-towing rope.Deck unit erection gantry should possess following radical function: (1) can realize the fixed vertical lifting at main push-towing rope horizontal segment and tilting section; (2) can unloaded telephone-moving on main push-towing rope, particularly can cross over the cord clip framing member on the main push-towing rope.
The deck unit erection gantry load larrying member mainly are made up of two end carriages and a carrying crossbeam.Usually end carriage is provided with two load-bearing bearings and traveling roller: deck unit erection gantry acts on the main push-towing rope by bearing during lifting; Deck unit erection gantry is supported on main push-towing rope by walking wheel during telephone-moving.Four telescopic walking wheels of every end carriage operated by rotary motion, and by the flexible walking wheel of oil cylinder effect, the realization deck unit erection gantry is marked time and is crossed over the main push-towing rope cord clip.The deck unit erection gantry traveling is a traction power with the winch wire rope block group on the cat head door frame usually.
The elevator system of deck unit erection gantry has two kinds of winch elevator system and hydraulic lift systems.The winch elevator system has fast, the simple to operate but winch of hoisting speed and characteristics such as the rope hoisting system is huge, lifting weight is less; Characteristics such as hydraulic lift system has that lifting weight is big, scantling of structure is little but hoisting speed is slow, complicated operation.
Common winch elevator system is implemented at 4 to hoisting structure and is lifted mode.This makes elevator system need four winchs and quadruplet polyspast, and need lay two cover load-bearing carrying crossbeams on main push-towing rope.Cause load larrying member, winch and rope hoisting system huge.Bring installation, various, the operating difficulties of telephone-moving operation thus, require at 4 when lifting especially and lift speed synchronization.
The beam prefabricated sections of case generally by barge be transported to cast anchor under the main push-towing rope in place; For the nearly tower place in shoal and nonirrigated farmland, generally by setting up trestle and being transported to lifting position under the main push-towing rope by chassis.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide a kind of simple in structure, easy to operate, cost is low, construction safety, is convenient to very much effectively rise the deck unit erection gantry that re-mounts the beam prefabricated framing member of large-scale steel case.
To achieve these goals, the technical solution used in the present invention is: a kind of deck unit erection gantry, include two pylons, winch, play hanging pulley, bearer cable, winch is located at the top of pylon, the top of bearer cable and two pylons is to connecting, winch drives the lifting coaster by hauling rope and slides along two parallel bearer cables, described hanging pulley is by two end carriages, article one, carry crossbeam, fixed pulley, movable pulley is formed, fixed pulley is located on the carrying crossbeam, at fixed pulley, be wound with lifting rope on the movable pulley, it is characterized in that: the upper surface at two end carriages is respectively equipped with hinge base, and the both ends of carrying crossbeam are connected with the end carriage hinge by hinge base; Described movable pulley is connected with the center of gravity place that shoulder pole girder and point of connection are positioned at shoulder pole girder.
The bottom of described end carriage is provided with walking roller and anchor ear, and anchor ear is socketed on the bearer cable, and the both sides of end carriage are provided with side retaining roller.
Also be provided with wheel flutter on the described carrying crossbeam.The effect of wheel flutter is to help the control that turns to suspended object.
Beneficial effect of the present invention: these deck unit erection gantry load larrying member stressed reasonable, simple in structure, easy to operate, cost is low, construction safety, especially be convenient to effectively rise re-mount the beam prefabricated framing member of large-scale steel case.
