Abstract
The invention discloses a single-beam loading test vehicle. The single-beam loading test vehicle can realize fast loading in a single-beam loading test in bridge engineering. The single-beam loading test vehicle solves the problems of the loading method of the traditional single-beam loading test, and fills in the blank of utilization of safe and reliable packaged equipment in test loading. The single-beam loading test vehicle is characterized in that a base is fixed to the tail of a carrying vehicle; a horizontally-rotatable and vertically-lifting counter-force crossbeam is fixed to the base; a horizontally-rotatable and vertically-lifting crane is fixed to an upper end of the counter-force crossbeam; through rotation and lifting (or dropping), the counter-force crossbeam stretches across a detection fracture surface of a test beam; a hydraulic support leg fixed to the end of the counter-force crossbeam are stretched thereby being supported by the ground; through the horizontally-rotatable and vertically-lifting crane, weights are lifted and carried to a balance weight platform of the end of the counter-force crossbeam; a slideable dual control dynamometer below the counter-force crossbeam is moved; and aiming at the detection fracture surface, the slideable dual control dynamometer is stretched so that acting forces and counter-acting forces are produced among the counter-force crossbeam, the dual control dynamometer and the test beam and thus test vehicle loading is realized.
Description
Affiliated technical field
The present invention is a kind of in the science of bridge building, when the naked beam loading test of monolithic detects, and the inspection vehicle that loads fast.
Background technology
At present, the naked beam loading test of monolithic detects in the science of bridge building, generally adopt artificial preloading, hang by machinery and move, manually set up the counterforce device that support forms " shoulder pole is carried a load " formula then, or adopt machinery to mention mass, use the mass of lifting jack top-hung sky then, test beam is formed counter-force etc., reach the purpose that the test beam loading is detected.Tradition single-beam loading test loading is time-consuming, the link of requiring great effort, intersect is many, on-the-spot testing conditions is required high.
The artificial counterforce device that forms is lifting jack, LOAD CELLS, highly regulates backing plate and avoid the distribution beam of concentrated force failure test back, and assembling combination forms.Test beam has non-uniform settling when as assembly unit deviation or loading being arranged slightly, under huge tension force effect, just may topple or collapse, and has very big personal security hidden danger.
Summary of the invention
In order to solve the deficiency of traditional single-beam loading test loading method, fill up during the single-beam loading test loads, do not have safe and reliable, the blank of packaged equipment.Single-beam loading test inspection vehicle of the present invention not only can be accomplished limited by on-the-spot testing conditions, and unified loading method eliminates safe hidden trouble, and can significantly reduce disposable input and loss that single-beam loading test loading brings, increases work efficiency.
The technical solution adopted for the present invention to solve the technical problems is: at the delivery hull back, fix one and act as counterweight and the pedestal that is connected effect, fixedly connected one has enough rigidity on pedestal, but can horizontally rotate the counter-force crossbeam of VTOL (vertical take off and landing).Again in counter-force crossbeam upper end, fixingly both can horizontally rotate, again the vertical lifting suspension transferring machine of landing.During work, by control system rotation and liter (or falling) counter-force crossbeam, make it test section across test beam.Stretch the hydraulic leg that is fixed on counter-force crossbeam termination again, form on ground and support.Then by the lifting suspension transferring machine, balancing weight is winched on the counterweight platform of counter-force crossbeam termination, slidably " two control dynamometer " under the mobile counter-force crossbeam again, alignment test beam test section, stretch the lifting jack of two control dynamometer lower ends, between counter-force crossbeam, two control dynamometer and test beam, form one and utilize acting force and reacting force principle to realize, safety, reliably, precisely, the inspection vehicle of single-beam loading test efficiently.
The invention has the beneficial effects as follows, not only can well solve on traditional single-beam load method, time-consuming, effort, unsafe problem, and can realize being subjected to hardly on-the-spot testing conditions to limit, significantly reducing the single-beam loading test loads, the disposable input and the loss that bring are increased work efficiency.

Label shown in the accompanying drawing: 1. carrier loader, 2, pedestal, 3, first horizontal rotating shaft, 4, lifting hydraulic pressure top, 5, counter-force crossbeam, 6, second horizontal rotating shaft, 7, vertical rotating shaft, 8, the lifting suspension transferring machine, 9, hydraulic leg, 10, the digital indicator of weighing, 11, balancing weight, 12, oil pressure gauge, 13, two control dynamometer, 14, the counterweight platform, 15, test beam, 16, slip T shape piece, 17, LOAD CELLS, 18, lifting jack, 19, bearing, 20, power distribution beam, 21, control system.
Embodiment
In Fig. 1, at delivery car body 1 afterbody, fix one and act as counterweight and the pedestal 2 that is connected effect, fixedly connected on pedestal: first horizontal rotating shaft 3 that the counter-force crossbeam is horizontally rotated can make the lifting hydraulic pressure of counter-force crossbeam 5 liftings push up 4.The fixing counter-force crossbeam 5 and can make second horizontal rotating shaft 6 that lifting suspension transferring machine 8 horizontally rotates, vertically rotating shaft 7 and lifting suspension transferring machine 8 in 4 upper end on lifting hydraulic pressure top.
In example shown in Figure 2, during work, utilize control system 21, according to the test depth of beam, by lifting hydraulic pressure top 4, jacking counter-force crossbeam 5 is controlled 3 rotations of first horizontal rotating shaft again to being fit to the rotation height, makes counter-force crossbeam 5 across test beam 15 test sections.According to test beam 15 height, regulate the height on lifting hydraulic pressure top 4 again, to reach counter-force crossbeam 5 to test beam 15, detect the requirement of desired height, stretch the hydraulic leg 9 of counter-force crossbeam 5 terminations again, form on ground and support.Then by lifting suspension transferring machine 8, balancing weight 11 is winched on the counterweight platform 14 of counter-force crossbeam 5 terminations, mobile counter-force crossbeam 5 times slidably " two control dynamometer 13 " again, alignment test beam 15 test sections, stretch two control dynamometers 13, at digital indicator 10 and the oil pressure gauge 12 of weighing, under the dual control to loading force, realize test beam 15 is carried out precisely, loads reliably.
Fig. 3 is the cross-sectional view of two control dynamometers 13, hinged by slip T shape piece 16 upper ends and counter-force crossbeam 5, lower end and LOAD CELLS 17, lifting jack 18, bearing 19 and avoid the power distribution beam 20 of concentrated force failure test back, fixedly connected from top to bottom, form whole.Before the test, can be according to detecting requirement, by bearing 19 rotations, adjust test beam 15 and power distribution beam 20 the angle of cut.Stretch lifting jack 18 then, make counter-force crossbeam 5, slip T shape piece 16, LOAD CELLS 17, lifting jack 18, bearing 19, power distribution beam 20 inside, and and test beam 15 between form acting force and reacting force.Because between counter-force crossbeam 5 and test beam 15, an integral body is only arranged, transmit, measure and show two control dynamometers 13 of acting force and reacting force, so can easily realize test beam 15 safe, efficient loadings.
