Abstract

A concrete bridge-checking device relates to an equipment for diagnosing the service state of a concrete bridge. The utility model comprises a checking platform-car, a track, a track supporting stand, and an embedded part. The checking platform-car comprises a running trolley, a driving mechanism, an operating platform, a working platform, a lifting mechanism, and a rotary mechanism. The track for the walking of the running trolley is welded on a bracket of the track-supporting stand of which rod units are welded on a steel plate of the embedded part of the bridge. When in checking the concrete bridge, the running trolley walks along the track and is driven by the manpower and dynamic power. The working platform is driven by the lifting mechanism to lift up and down and is driven by the rotary mechanism to rotate, which leads the working platform to reach the operating position to check the bridge. The utility model is rational in structure, simple in operation, and strong in practicability with wide application range and is applied to the checking on railways, highways, and bridges.

Description

The concrete-bridge testing fixture

Technical field the utility model relates to a kind of equipment of diagnosing the concrete-bridge user mode.

Background technology has the maintenance and inspection device (see figure 9) of a kind of use on Existing Railway Concrete Bridges at present.It is made up of track assembly, traveling portion, hanging basket, working stand four parts.Track 33 is fixed on beam body diaphragm below by clamping plate and portal 31.Pull operation chain 32 can be operated this device along track travel.During the maintenance and inspection operation, need do following preparation: 1. hanging basket 38 drops to lowest order, and 2. four diagonal members 40 connect firmly with hanging basket, and 3. support roller 36 holds out against beam body 29,4. erects working stand 30.When passing through bridge pier, need above four steps reduction is rotated 90 ° to hanging basket then, cross bridge pier the neutral under operating personnel are auxiliary in the middle of bridge pier.

The problem that this device exists:

1, the track installation is the diaphragm that utilizes bridge, seems that gauge is narrower reluctantly;

2, be difficult to equilibrium problem and need take many measures for overcoming the narrow hanging basket that causes of gauge, thereby operation is more loaded down with trivial details;

3, only can be used for the railway T type beam that built up.

When bridge design, do not consider the inspection problem of bridge in the past, and brought many difficult problems for like this design of the testing fixture of back, brought many inconvenience yet to installation.Particularly to the especially big bridge of the railway of box, prior art can not be suitable for.

The summary of the invention the purpose of this utility model is at above-mentioned present situation, aims to provide a kind of design stage at bridge just to consider from now on inspection problem, and the testing fixture design is more reasonable, practical, the concrete-bridge testing fixture of wide accommodation.

The implementation of the utility model purpose is that the concrete-bridge testing fixture is by checking that chassis 9, track 13, track support 8 and built-in fitting 7 constitute.Check that chassis is made of traveling dolly 1, transmission mechanism 2, operating platform 3, working platform 5 and elevating mechanism 4 thereof, rotating mechanism 6.On the bracket that is welded on for the track 13 of traveling dolly 1 traveling, each rod member of track support is welded on the steel plate 11 of built-in fitting 7 of bridge.Power supply 28, motor 27 or foot-operated 26 wheels 22 by sprocket wheel 25, chain 24, sprocket wheel 23 drive traveling dollies.16 of working platform 5 and adjustable shelfs are connected with rotating shaft 20, and adjustable shelf 16 is by Chain block 17, pulley 14, wire rope pulling.Fixed mount 15 has the slideway that slides up and down for adjustable shelf 16.Handwheel 21 is arranged on the working platform, and handwheel switches through axle 20 by chain 18, sprocket wheel 19.

The utility model is by checking that chassis 9, track 13, track support 8 and built-in fitting 7 constitute (see figure 1).It mainly uses on newly built railway (or highway) concrete-bridge.

In the design stage of bridge, promptly in the position of each rod member of need welded rails support 8, pre-buried built-in fitting as shown in Figure 3 is after bridge is built up, with the steel plate 11 welding (see figure 3)s of each rod member of track support 8 and built-in fitting 7, track 13 is welded on (see figure 4) on the bracket of track support 8.

Position relation between inspection chassis 9 that is made of traveling dolly 1, working platform 5 etc. and track support 8, the built-in fitting 7 is seen Fig. 2.The inspection desk parking stall checks that in the below of 10 liang of side wing edges of bridge chassis can be along track 13 walkings, and every bridge block is furnished with two inspection chassis.

During the utility model work,

By foot-operated moving foot rest 26, drive sprocket wheel 25 (see figure 7)s, or drive sprocket wheel 25 (see figure 8)s by motor 27 by power supply 28, drive the wheel 22 of traveling dolly 1 again by sprocket wheel 23, chain 24, drive and check that chassis 9 is along track 13 travelings.

According to the difference of working position height, available Chain block 17 slides by the slideway of wire rope pulling adjustable shelf 16 along fixed mount 15, drives working platform 5 lifting (see figure 5)s, to adapt to the inspection to bridge differing heights position.

Move the handwheel 21 on the working platform 5, through chain 18 transmissions, working platform 5 is 20 half-twists around the shaft, form two stations before and after the rotation: i.e. working position and traveling position.Working platform is convenient to the staff and is checked bridge when working position; When the traveling position, be convenient to bridge pier.

When working platform also is in highest order simultaneously in the traveling position, check that chassis can cross bridge pier, the staff can finish the inspection to full bridge bottom surface, side and bottom surface, the edge of a wing.

The utility model uses on newly-built box-girder railway concrete bridge, also can be used on the highway bridge.

The utility model is rational in infrastructure, simple to operate, safe and reliable, practical, applied widely, can be used for the inspection of railroad bridge, highway bridge.
