Description
Technical field
The utility model relates to bridge expanssion joint construction field, is specially a kind of bridge expanssion joint installation and transportation device.
Background technology
For meeting the requirement of bridge floor distortion, conventionally between two beam-ends, expansion joint is set between beam-ends and abutment or in the articulated position of bridge, require expansion joint parallel, perpendicular to the both direction of bridge axes, all energy free-extensions, solid and reliable, Vehicle Driving Cycle out-of-date should be smooth-going, without kick and noise etc., mainly that variation in order to prevent temperature causes that expanding with heat and contract with cold of pavement structure is excessive and damages, in order to reduce earthquake harm, the effect that prevents that beam displacement body is excessive is also played at expansion joint now.
At present, expansion gap device is all to manufacture and assemble in factory, at the construction field (site) welding, but when heavier for expansion joint whole piece overlength, overall weight, manually cannot directly carry and install, while manually expansion joint being installed, conventionally cannot meet the requirement of flatness and precision. Common expansion joint transport and installation method have two kinds:
Method one: adopt crane to coordinate flat car transport, manually coordinate crane to install;
Method two: adopt crane, flat car transport, manually install.
The shortcoming of method one is: when transport and installation, need use crane handling, take a large amount of crane time; When crane is installed, well control plane position and elevation, can not well control construction quality; The shortcoming of method two is: when transport, need use crane handling, take a large amount of crane time; When artificial installation, spend a large amount of time, manpower and energy, and well control plane position and elevation, construction quality can not well be controlled.
Above two kinds of methods are traditional methods, take a large amount of crane time, and workman's labour intensity is large, and operating efficiency is low, and aligned position is adjusted position and need be taken the plenty of time, and well control plane position and elevation. For solving above two kinds of existing defects of method, in the urgent need to developing the device of the defeated installation one of a kind of transporting something containerized, easy construction, easily in place, more save time, more can ensure construction quality.
Summary of the invention
The utility model adopts above-mentioned two kinds of methods in order to solve existing expansion joint installation and transportation, has the problems such as labour intensity is large, efficiency is low, installation accuracy is low, and a kind of bridge expanssion joint installation and transportation device is provided.
The utility model is to adopt following technical scheme to realize: a kind of bridge expanssion joint installation and transportation device, the installation walking mechanism that comprises haulage gear and be connected with haulage gear, innovative point of the present utility model is to install walking mechanism and comprises at least two door type installing racks that be arranged in parallel, the crossbeam centre position suspention of each type installing rack has jack, two root post lower ends of each type installing rack are all fixed with two oblique mounting rods and a horizontal mounting rod, form triangle installing rack, two universal wheels are installed in triangle installing rack below, be positioned on door type installing rack two root posts foremost and be provided with tow attachment, haulage gear passes through traction bars, tow attachment is connected with installation walking mechanism.
In order further to optimize the structure of this installation and transportation device, improve its function, the utility model has also carried out following architecture advances:
Described haulage gear is four-wheel tractor or tricycle.
Between two root post upper ends of each described type installing rack and crossbeam, install and strengthen support bar, make a type installing rack overall structure more stable.
This described installation and transportation device also comprise across bridge expanssion joint notch cross seam trestle, cross and stitch trestle and strengthen supporting and form by crossing the I-steel that stitches steel plate and be welded on seam steel plate below in parallel. Bridge expanssion joint is transported to behind installation site, and door type installing rack need be across expansion joint notch, and the effect of excessively stitching trestle is to ensure that a door type installing rack strides across expansion joint notch.
Installation and transportation device described in the utility model is made up of four parts, formed by haulage gear (four-wheel tractor or tricycle), travel mechanism's (multiple type installing racks that be arranged in parallel), derricking gear (jack) and mistake seam trestle respectively, a set of travel mechanism is made up of multiple type installing racks, lifts Huo Ji road bridge expanssion joint one by jack at every turn; Adopt four-wheel tractor or tricycle as transport traction power, by pulling tow attachment moving door type installing rack and the expansion joint on a type installing rack, be transported to the on-the-spot rear artificial door type installing rack that promotes, crossing under the effect of stitching trestle by expansion joint notch, then use jack control expansion joint elevation of top surface and flatness, use the plan-position at moving door frame Position Control expansion joint.
Compared with prior art, the utlity model has following advantage: 1, this device transporting something containerized defeated, be installed as one, volume is little, lightweight, operation and maintenance is convenient; 2, use jack lifting, the transport of door type installing rack, three people get final product complete operation, have greatly alleviated workman's labour intensity, have improved operating efficiency; 3, can reduce the use of crane or other hanging devices, greatly reduce construction cost; 4, work progress can well be controlled construction quality. In a word, the utility model has solved expansion joint transportation problem, the difficult problem such as elevation of top surface, flatness and plan-position while having solved installation, and convenient transportation when construction, easily in place, more save time, more can ensure construction quality, there is good application value.
