Description
Technical field
It is particularly a kind of for steel pipe truss concrete arch-type bridge suspender replacement the present invention relates to a kind of bridge construction equipment
Instrument derrick rig.
Background technology
At present, most of steel pipe truss concrete arch-type bridge suspender replacement rope power conversion devices are mainly interim suspension rod or interim
Part need to take welding manner to fix leveling wedge or antiskid block on pocket device for hoisting, arch, reach that the upper leveling of arch is easy to set
Crossbeam or the purpose of antiskid；It has the disadvantage：Engineer operation intensity is big, the hardly possible control of Site Welding quality, easy injury of primary tubular arch
Rib and application, wedge can not be used in turn, and dismounting resumes operation, and progress is slow, and construction cost is higher.
To solve the above problems, Patent No. 201520814605.4, entitled：It is " a kind of mixed for steel pipe truss
The towed instrument derrick rig that solidifying soil arch bridge suspender is changed ", the patent No. 201521046495.8 is entitled：" one kind is led
Draw frictional anchoring suspender replacement device " two kinds " arch bridge suspender changes rope power conversion device " are successively disclosed, solve above-mentioned
The technical problem that prior art is present, but all there is more, the problem of manufacturing cost is higher that be related to mach component, particularly
The towed vault anchoring antiskid system construction size set in vault is larger, less practical in some areas.
The content of the invention
It is an object of the invention to provide a kind of hood type instrument suspension rod for steel pipe truss concrete arch-type bridge suspender replacement
Device, the hood type instrument derrick rig is simple in construction, size is smaller, is related to that mach component is less, and manufacturing cost is relatively low.
The technical scheme solved the above problems is：A kind of hood type work for steel pipe truss concrete arch-type bridge suspender replacement
Have derrick rig, including：Entablature, stretching end anchorage I, upper interim rope, stretching end anchorage II, conversion beam, fixing end anchorage I,
Interim rope, lower joist and fixing end anchorage II down；It is characterized in that：The hood type instrument derrick rig is also arranged on including one
Hood type vault anchoring antiskid system on steel pipe truss concrete arch bridge arch, the hood type vault anchors antiskid system by inserting
Pin, suspender belt, anchoring anchor ear, leveling steel case, entablature, antiskid rope and antiskid anchor ear composition, anchoring anchor ear one end by latch, hang
Band is anchored on steel pipe truss arch ring with canoe, one end of antiskid rope is fixedly connected with anchoring anchor ear bottom, the other end with
Antiskid anchor ear bottom is fixedly connected；Twisted between the antiskid anchor ear and anchoring anchor ear of hood type vault anchoring antiskid system by steel
Line or push-and-pull rod connection；
Under working condition, upper interim Suo Shangduan is anchored through entablature stretching end anchorage I, and upper interim rope lower end, which is passed through, to be turned
Beam is changed, is anchored with fixing end anchorage I, lower interim Suo Shangduan sequentially passes through conversion beam, jack, is anchored with stretching end anchorage II,
Interim rope lower end is anchored through lower joist fixing end anchorage II down, and lower joist catches suspender crossbeam lower surface；Leveling steel case is pacified
Between antiskid anchor ear and entablature, arch entablature leveling is realized.
Its further technical scheme is：The anchoring anchor ear is made up of two halves formula steel hoop and anchor case, two halves formula steel hoop
Connected by high-strength bolt, pretension high-strength bolt realizes antiskid, anchor case is fixedly connected and is connected by latch with the top of steel hoop
Mode is connected with suspender belt, and suspender belt is anchored on steel pipe truss arch ring by canoe.
The antiskid anchor ear is two halves formula steel hoop structure, is connected by high-strength bolt, pretension high-strength bolt realizes antiskid.
The two sides of the leveling steel case are that wedge-shaped steel plate, another two sides are shape of a saddle steel plate, and top surface is rectangular steel plates, are spelled
It is welded into steel box structure.
Antiskid anchor ear on concrete arch bridge arch has between 2,2 antiskid anchor ears by steel strand wires or push-and-pull rod company
Connect.
Due to using above-mentioned technical proposal, a kind of anchor ear for steel pipe truss concrete arch-type bridge suspender replacement of the present invention
Formula instrument derrick rig has the advantages that：
1. the device does not change original structure stress system in suspender replacement Suo Li transfer processes, to original structure stress shadow
Sound is smaller：
The present invention has one to be arranged on for the hood type instrument derrick rig of steel pipe truss concrete arch-type bridge suspender replacement
Hood type vault anchoring antiskid system on steel pipe truss concrete arch bridge arch, the hood type vault anchors antiskid system by latch
24th, suspender belt 10, anchoring anchor ear 9, leveling steel case 4, entablature 5, antiskid rope 8 and antiskid anchor ear 3 are constituted, and anchoring anchor ear 9 one end leads to
Cross latch 24, suspender belt 10 to be anchored on steel pipe truss arch ring with canoe, one end and anchoring anchor ear 9 bottom of antiskid rope 8 are consolidated
Fixed connection, the other end are fixedly connected with the bottom of antiskid anchor ear 3；The antiskid anchor ear of hood type vault anchoring antiskid system and anchoring
Connected between anchor ear by steel strand wires or push-and-pull rod, to realize the purpose that antiskid is anchored on arch；
