Description

A moving apparatus of bridge working pulley

The present invention relates to a traveling device of a mobile work vehicle installed under the bridge top plate for inspection and repair of the bridge, and in particular, a support of a fixed distance in the longitudinal direction of the beam is fixed to the outside of the box-shaped beam supporting the bridge top plate. And a rail disposed at an upper portion of the auxiliary rail disposed in the longitudinal direction of the beam at the end of the support, and a wheel, which is a driving unit of the work vehicle, is coupled to the rail to travel the work vehicle.

In order to inspect and repair a conventional bridge, it is true that heavy scaffolding has been used to install scaffolding under the bridge for a long time.

As the above work is not only time-consuming but also expensive and the work support is performed at the top of the bridge, there is a problem of traffic control, and even when using a work car, a rail supporting the work car generally has a beam. It is disposed at the bottom of the structure so that the work vehicle is suspended vertically, so there is a problem in stability, and because the rail is disposed at the bottom of the beam, there is difficulty in the excavation work itself. There is a problem.

The present invention is to install the support to protrude from the beam at regular intervals on the outside of the box-shaped beam for supporting the top plate of the bridge, to arrange the auxiliary rail in the longitudinal direction of the beam at the end of the support and to install a rail on the upper part of the auxiliary rail The driving part of the wheel is configured to drive on the rail, so the above installation work is performed near the top plate, which can eliminate the difficulty of work, and the work car installation work is easy, and the wheel is located on the rail in the combination of the wheel and the rail. The purpose is to provide a device that can improve the workability and stability during operation of the work car.

The feature of the present invention is to use the short span of the bridge is configured to be used for long bridges.

The present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the present invention has a support 12 having a predetermined length so as to protrude from the beam 17 outside the beam 17 of the bridge and is formed in the shape as shown in the detail of FIG. ) The end is formed with the step 27 in the upper direction and the auxiliary rail 18 coinciding with the step 27 is fixed to the step 27 and installed in the longitudinal direction of the beam 17 and the auxiliary rail 18 Above, the rail 13 is disposed as shown in FIG. 3, and the rail 13 is coupled with a wheel 14 having a groove 25 formed on the circumference thereof, and the wheel 14 is linked with the power 20 and the power ( The left and coupled to the rotary shaft 23 for transmitting the rotational force of 20). The cover 24 is coupled to the right side to protect the quiet rotation of the wheel 14, and includes a cover 26 to protect the wheel 14 including the power 20.

Referring to the present invention as an embodiment,

Rigid steel bridges, which are constructed as described above, are bridges constructed by construction work on the sea, rivers and valleys, so it is necessary to check the bridges for any abnormality. There is a need to avoid the risks.

The present invention is installed on the new bridge, the new bridge of the bridge as described above, in particular, the beam for supporting the upper plate 15 is installed in the bridge consisting of a steel box type to support the lower structure of the bridge, the state of the beam, the beam It is installed to inspect and repair the condition of the bridge 16, the corrosion of the coating, etc., and generally relates to a traveling device of a mobile work vehicle, which is installed in a short span.

In order to inspect and repair a conventional bridge, a heavy duty machine is used to install a scaffold in the lower portion of the bridge for a long time, or when the work vehicle 11 is used, a rail 13 supporting the work vehicle 11 is generally provided. Although work has been carried out with a work vehicle 11 having a structure arranged on the bottom of the beam 17 and suspended vertically, such a work is not only time-consuming but also expensive, and work support is provided on the top plate 15 of the bridge. There is a problem to control traffic because it is made in the case of the work vehicle 11 of the structure suspended on the bottom of the beam 17, there is difficulty in the excretion work itself, if the external pressure occurs in the transverse direction in the work vehicle 11 It can be predicted that the wheel 14 can escape from the rail 13.

The present invention is a structure that can solve the above problems.

Regardless of whether the box-shaped beam 17 is composed of a single or a plurality of boxes, the box 12 of a box-shaped or H-shaped steel of constant size having sufficient tension outside the beam 17 is firmly projected from the beam 17. Fix 17) but install several supports 12 at regular intervals.

A step 27 is formed so that the end of the support 12 is stepped upward, and the auxiliary rail 18 of the H-shape corresponding to the step 27 is disposed in the longitudinal direction of the beam 17 and the step ( 27) and fix it firmly.

The rail 13 is disposed along the auxiliary rail 18 on the auxiliary rail 18 disposed as described above.

As shown in Figures 1 and 2, the work table is formed in a truss shape and at both ends. The lift 19 which is telescopic downward is mounted and the lift 19 is left. On the right side, the power 20 is installed, the rotating shaft 23 is connected to the power 20 and transmits power to the inside of the workbench, and the end of the rotary shaft 23 is formed with a groove 25 in the circumference wheel 14 ) Is inserted and left of the wheel (14). In this case, a cover 24 for protecting the wheel 14 is installed.

The wheel 14 of the workbench formed as described above is coupled to the rail 13 and the wheel 14 securely places the load of the work vehicle 11 on the rail 13 so that the wheel 14 is secured to the rail 13. A work vehicle 11 capable of slipping on the upper surface and a work platform that can move a short span is completed to easily check and repair the bottom and both sides of the beam 17, and the transverse external pressure or traffic volume caused by wind power. Regardless of the vibration of the bridge by working safely can maximize the stability and efficiency of work.

The work vehicle of the bridge according to the present invention places the load on the rail, so that the wheel is difficult to detach from the rail, and even if the wheel is detached from the rail, the fall of the work vehicle is prevented and the position of the traveling device supporting the work vehicle Since it is close to the virtual plate, it is easy to work organically when installing the traveling device, and the work vehicle is supported on both sides of the beam, so it is safe to external pressure in the transverse direction, thereby improving the safety and workability of the work.
