Abstract

The present invention relates to a mobile bridge inspection work vehicle.

In order to perform bridge inspection and maintenance work, various types of fixed inspection road, permanent inspection car, articulated car, aerial work vehicle, fixed scaffolding, mobile scaffolding, etc. are applied, but none of them completely satisfy all the work. There is a problem that multiple forms must be used in combination. In particular, even in the case of the permanent type inspection car, even though the variety of uses is theoretically recognized, it may be several tens of tons depending on the site, and it is difficult to check and repair the equipment itself, and the equipment itself is expensive and the management cost is high. As a result, they had to fail in wide use.

The present invention relates to a device that allows a light inspection stand to be fixed to the pier at each interval in a high-fixed form, while at the same time releasing the fixed state and moving and repairing and inspecting the entire leg. That is, since the inspection platform does not necessarily have to pass through the pier, it reduces the cost and weight, which is a chronic problem of the conventional permanent inspection vehicle, and makes it possible to employ universally not only a special pole bridge but also an existing general bridge and an elevated bridge.

Description

Mobile and fixative bridge maintaining system

The present invention relates to a mobile bridge inspection work system widely used from the safety diagnosis of the bridge to the inspection and maintenance work. In particular, the main inspection stand is a permanent bridge fixed type fixed to the piers and, at the same time, it is a mobile bridge inspection work vehicle configured to enable the maintenance of the whole bridge while releasing the fixed state by moving with the running rail when necessary.

The following is a comparison of the bridge management system equipment.

Various facilities and equipments in Korea are limited in their use for inspection and work, so there is a limit to their wide application to inspection and work as a whole.

First, the fixed inspection is generally installed for intensive inspection of bridges, bridges, etc., but the access rate to the bridge is extremely low, so the bridge inspection effect is less than the investment cost. In the case of the inspection vehicle, the weight of the vehicle may be several tens of tons depending on the site, but the maintenance of the inspection vehicle itself is difficult, and the equipment itself is expensive. Due to the high management cost, wide use will fail. The installation of these inspection vehicles exposes tremendous problems from installation costs to maintenance. Specifically, as shown in Fig. 13 (Gumcheon bridge installation photo) and 14 (Gimpo bridge installation photo), several tons are installed. A huge main checkpoint and a device for its movement are installed, and it passes through the rotation by using a control device and a powerful hydraulic system that require high precision and safety on both sides for the passage of the bridge. As shown in the photograph of Fig. 15, the center of the inspection stand is separated as shown in the photograph immediately before the rotation of the center portion, and when rotated at both ends, the inspection stand goes out of the pier and is not caught by the pier. Despite the great advantages it has, the installation costs are enormous, and the complex control system and hydraulic cylinder As such equipments are easily aging because they are always installed on bridges exposed to the outside, another management cost and input of professional personnel are required for the management of these devices themselves. Refractive cars and aerial work vehicles that are used are not fixed to the bridge, so there is a problem in use at sea, river or valley, and inevitably requires traffic control.

Third, fixed scaffolds (aka aerial scaffolds), which are generally installed in the repair work of bridges, are not suitable for inspection, and even if the workability is recognized, safety accidents are frequent and pointed out as fatal drawbacks.

Fourthly, the multi-period permanent inspection is widely used for inspection and partial repair, but it has heavy weight because it has to install hydraulic system and huge truss structure in various axial directions for the passage between piers. Due to the high installation cost, it is difficult to apply general purpose to general bridge except some special bridge.

Fifth, mobile scaffolds (aka rack work vehicles) used for inspection and repair have the advantages of light weight and low cost, but except for some bridges (bridge type is a column type column type), it is difficult to pass through the pier. Scaffolding is easy to assemble and moveable, but the bolt nut assembled on the railing is loosened slowly as the work progresses (of course, if it is tightened enough to penetrate the railing, there is no problem but it is assembled without damage) In the end, it can not be installed permanently and is dismantled once after installation. It is indispensable to move and re-install such equipment during maintenance inspection of different piers.In addition, it is unavoidable to bend the middle of lightweight steel aggregate in the long bridge (usually when more than 4 lanes are installed). If it is used as a non-bending steel, the weight is enormous and cannot be used as a prefabricated material.Even if it is a lightweight material, as described above for this span relocation, it is expensive and weighs more than 10 tons, Various work equipments must be mobilized, so most of the bridge inspections are carried out using equipment such as aerial work vehicles and articulated work vehicles as needed. In rivers, it is useless if there is no mobilization of other special equipment. C. Because of these problems, there is only current needs but is recognized for most of the bridge to stay on the extent helplessly as superficial remote visual inspection.

The present invention allows the drive unit to pass through the pier in order to solve the problems of the passage of the scaffold (rack work car), while at the same time eliminating the above-mentioned enlargement of the permanent type inspection car, limitations of installation and maintenance defects. The workbench is installed separately for each span so that it can be moved even in the span alone. That is, in each span, the inspection stand is installed as a permanent type, and the inspection of the bridge part is possible at any time, as well as free movement is possible when combined with the running rail, so that the front surface maintenance work on the bottom of the bridge is also possible. In addition, it is easy to install, dismantle, and relocate the running rails, so that the running rails can be rented without any burden.The checker is lightweight, so that the reinforcement of the bridge itself can be applied to the old or small bridges with weak durability. It can be installed without the need for installation work, and it is intended to provide a free inspection car for disassembly. The inspection table can also be fixed like a permanent type, and it can also be constructed as a movable assembly so that if necessary, it can be dismantled and stored at a minimum. It is to be able to inspect many bridges in the vicinity by the number of inspection stand.

The present invention is to install a rail device such as a rail or I beam specially manufactured in the weld flange portion or plate portion of the bridge to eliminate the enormous weight and cost burden of the conventional permanent inspection car and vertical trusses, flat plate, It consists of a truss reinforcement, and then attaches a driving car to move by magnetic force, and it relates to a mobile bridge inspection system that can be arbitrarily dismantled and assembled as these devices are all assembled.

In particular, in order to solve the safety problem when installing a simple scaffolding checker, it adopts a fixing method that guarantees stability like the permanent fixation, and combines the light weight of the scaffolding with the ease of assembly and disassembly. Overcome the difficulties

The present invention can be applied to any type of bridges, since the traveling device and the assembly system of the present invention can be installed in order not only steel bridge type bridges but also cantilever extends from side to side and can be difficult to access by general means. The aim is to provide this possible portable bridge inspection vehicle.

The present invention and the running rail portion installed in the longitudinal direction of the steel bridge, concrete bridge

In the state installed in the running rail portion, the power generating unit consisting of an engine, a battery, and other power generating device for moving the main inspection stand and

The main inspection stand (main work bench) made of a box type of vertical truss, flat plate, truss reinforcement and the like is coupled to the power generating unit and the horizontal connecting rod and towed by a driving vehicle, and is a main component of the mobile bridge inspection apparatus.

Specific embodiments of the present invention will be described with reference to the accompanying drawings.

There are various types of bridges, but most of them are steel bridges such as steel box type and plate girder type, and there are two types of concrete bridges with protruding cantilever parts.In addition, there are special bridges such as truss bridges, cable-stayed bridges, and suspension bridges. There is this. Here, the steel box type and concrete bridge will be described as a representative example to explain the installation and operation relationship.

1 is a front view showing a state in which the apparatus of the present invention is installed on a steel bridge as a whole, Figure 2 is a detailed side view showing an installation state for the bridge inspection work of the present invention, Figure 3 is an installation for the bridge inspection work of the present invention Fig. 4 is a side view showing the installation state of the bridge inspection work vehicle of the present invention as a whole. The work rail is installed in the longitudinal direction of the bridge, and the worktable is arranged in the longitudinal direction of the bridge. In the bridge inspection system in which the work vehicle is integrally formed or only the work vehicle moves independently along the lateral direction of the bridge, the bridge inspection system is capable of repairing the bridge, and the upper side of the lower member 29-3 of the inverted triangular structure. According to the length of the piers, the cantilever 29, in which the side thrust structure in which the reinforcing member 29-4 is integrated in the U shape, is integrally formed by the connecting member 29-5. Continuously arranged in parallel in the longitudinal direction of the amount by the fastener (29-6), and arrange the thrust structure (T) for the workbench above the lower member, the width (L) of the thrust structure is the width of the piers (L-1) The base B, which is configured to be longer, is fixed to the pier side of the bridge, and has a rear surface of the planar structure 12 so that one surface is in contact with the weld flange or plate portion P of the bridge, and a plurality of racks are provided on the opposite side thereof. The upper rail which can be assembled and disassembled arbitrarily by the primary vertical connecting rod 31 so that the driving rail is fixed to the rack rail 15 having the gear mount 14 formed by the clamp 13 in the longitudinal direction of the bridge. Mobile work inspection of the bridge, characterized in that the loading platform 37 is installed on the side by the joint (j) of the side while the work vehicle is assembled by the vehicle 23-1 and the lower follower 23-2 as a medium To a working vehicle. Since the width of the bridge structure is configured to be longer than the width of the bridge, it is possible to pass through the bridge when it meets the bridge without using complicated rotating equipment such as the permanent type.

The running rail portion of the present invention is a form in which many rack gear mounts 14 are attached to the plate portion 12, and may be temporarily installed using various prefabricated clamps 13, depending on the shape of the bridge, or EYE type if necessary. It is also possible to install the running rail by fixing the bracket. If the running pitch of the running rail is inevitably far, a truss-type running rail may be used.

In the present invention, the drive car 21 is installed in the running rail portion to function to pull the main inspection stand 11, itself may be internally built in power such as an internal combustion engine or battery, or (feeding from a generator or other power supply) It may also be equipped with only a motor. Various control switches are installed on the surface of the driving vehicle 21 and the electric panel (aka control box) for controlling the driving vehicle to control the speed, direction, and various safety devices arbitrarily.

In the present invention, the hanging portion has a function to transfer the traction force from the driving vehicle 21 to the main inspection stand 11, the configuration of which is a horizontal connecting rod 81, the upper driven car 23-1, the lower driven car ( 23-2) and the first vertical connecting rod 31 between the upper and lower driven cars. The upper follower is attached to the running rail and the lower follower is attached to the main inspection stand. In particular, the upper follower is connected to the driving vehicle by a horizontal connecting rod and is towed by the driving vehicle.

In the present invention, the main inspection stand (working table) is a rack gear having two vertical trusses 33 attached to the top and a flat plate 32 placed on the inner bottom thereof, and a truss reinforcement for mutually supporting the two vertical trusses ( 40). The two vertical trusses are the basic frame of the main inspection frame and several truss types are applied for the 'maximum load weight of the smallest element'. In addition, a rack gear mount is attached to the top of the vertical truss, and its purpose is not only to install the inspection stand in the width direction at the bottom of the bridge or to facilitate the side movement, but also to install various optional equipment such as a separate vertical work platform 58 thereon. It also functions as a 'going rail' when seated and driven left and right. A separate flat plate 32 was installed on the floor to allow the worker to work stably. Deck plate, EX-METAL, and other perforated scaffold can be used as flat plate types. The truss reinforcement 40 serves to mutually support and reinforce two vertical trusses 33. Depending on the location of the running rails, the loading work platform 37 may be additionally installed by the joint j for installing the loading work bench, which may be used during work such as extension installation or dismantling of the running rail unit or other work.

5 to 8 show another embodiment showing a front view, a side view showing an installation state for the concrete bridge of the present invention.

Although operated on the same principle as the steel bridge described above, concrete bridges are specially protruded cantilevered portions, so the left and right check stands 50 are separately installed.

The running rail can be installed similarly to the installation of the steel bridge in the main school, and if necessary, a bracket of EYE TYPE can be attached. To install the running rail without the installation of such an auxiliary device, as shown in FIG. ) Can be hung on a firewall or the like to hang a running rail.

The left and right checkpoints are installed from the running rail to the lower side, which has a complex function. The functions of the left and right checkpoints must first be able to check the cantilever, and can be equipped with equipment such as the cantilever check vertical work bench (58). Minimize the installation cost of the main inspection stand (11-1). The left and right checkpoints are separated from the main checkpoint when they meet the pier, and each runs the running rail 15-1 of the outer line and passes through the pier independently, so as to prevent the rotation moment, the upper checkpoint 54 and the lower checkpoint ( 57) and the center of gravity of the vertical workbench (58), etc., were placed directly under the running rails. Therefore, in the worst case, even if the worker moves to the end, the shaking is very small due to the weight of the check table. In addition, the lower check stand 57 of the left and right check stands was supported by four points from the upper check stand 54 without hanging directly from the running rail, thereby reducing the moment change when the lower check stand was separated from the main check stand. In addition, the moment prevention rotation roller 62, the balance weight, and supported the moment prevention.

Looking specifically at the structure, after the bracket hanger 51 is extended to install the running rail, the drive rail 21, the upper driven car 23-1, the lower driven car 23-2 ), The upper inspection stand 54 is installed together with the primary vertical connecting rod 31 and the like. Subsequently, the lower inspection table 57 is installed by the secondary upper driven vehicle 24-1, the secondary vertical connecting rod 55, and the secondary lower driven vehicle 24-2. The vertical work bench 58 was built between the upper check bench 54 and the lower check bench 57. Vertical workbench is installed on the lower side of the vertical workbench driving car 60 and can be moved left and right using the vertical workbench running rail 63 and the driven car 61, and the vertical workbench is capable of moving the work plate up and down Access to any location on the lower part of the bridge was made possible.

As another embodiment of the present invention, as shown in FIGS. 9 and 10, the driving rail part and the driving part are partially changed, and the driving rail uses the I beam, and the driving car and the upper driven car are adapted to the I beam.

In the case of steel bridges, after the bracket 71 is welded to the welded flange or plate, the running rail part attached to the I beam is attached thereto;

Instead of the drive car 21 in which the pinion gear is built (fitting the rack gear), the drive car 73 and the driven car 74 of the rotary roller type suitable for the I beam are provided.

In the case of the concrete bridge, the I beam and the driving part corresponding thereto are changed as the running rails in the same form as the above-mentioned steel bridge. Install it. Other principles are the same as the above.

As another embodiment of the present invention, as shown in Figs. 11 and 12, the main inspection path is directly fixed to the main bridge without being placed on the cantilever 29. After attaching the bracket 91 of the EYE TYPE to the bridge, the fixed hanger 92 in the vertical direction is appropriately arranged according to the width of the main inspection path, and the main inspection path is put down. It is also supplemented with fixing braces 93 to prevent horizontal shaking.

In summary, the operation principle according to the overall structural features, the inspection stand is fixed to the pier at each interval in the form of fixed and fixed, and at the same time release the fixed state to move the maintenance of the entire bridge is possible.

The drive car 21 is installed on the running rail 15 with the rack gear, and the running rail is attached to the bridge by the clamp 13 or the bracket hanger 51. Finally, the main inspection stand 11 is normally pier side. It is settled in the cantilever 29 attached to it, and when it is in need, it is combined with the running rail by the hanging part, and when the work of one span is finished, the main inspection path is separated again, and the driving part continues to travel along the running rail and passes through the piers again. Continue with the inspection and repair work, re-combine with the main inspection of the next span.

The effects of the mobile bridge inspection work vehicle according to the structure of the present invention are as follows.

In the case of the permanent inspection car, the difficulty of passage of the bridge is found by the huge truss structure using the hydraulic system, and the solution of about ten tons is installed in the cantilever, the weakest part of the bridge, despite the superiority of the principle. Existing bridges that require maintenance cannot be installed and are currently being installed only on new bridges. In addition, even long bridges such as cable-stayed bridges, the permanent type inspection car with a heavy weight is not good for maintaining balance. In addition, due to its own weight, there is a limit to the work space and loading load required for the repair work of the bridge, and therefore, there is an economic problem of overlapping investment, which requires installation of separate equipment or conventional fixed scaffolding during the repair work.

On the other hand, the present invention is a system that can expect the integrated effect that does not require separate inspection and work equipment. In addition, the time and space constraints on bridge maintenance have been eliminated. In other words, since the mobile inspection platform exists every interval, quick inspection is possible, but when combined with a running rail in case of emergency, it is possible to carry out a comprehensive and comprehensive emergency inspection simultaneously. And because the weight of the inspection platform is light, it can be installed even on the existing bridge without the need for additional reinforcement. In addition, safety accidents that can occur during the installation and dismantling of fixed scaffolds (air scaffolds), which are commonly installed during maintenance work, can be reduced.

In terms of economics, the inspection and repair of the bridges are not separate devices, but integrated operation, thereby avoiding redundant investment in bridge management. And since it does not need to be a hydraulic system or a huge truss structure in comparison with the existing permanent type, it can be operated at low cost.

In order to maximize the effect of such low-cost equipment, firstly, the I-beam running rail may be selectively used. Rack rails with rack gears have advantages in that they can be easily disassembled and assembled, but the manufacturing cost is high, so the longer the bridge, the higher the running rail price, and some of the advantages in price competitiveness can be offset. If the user wants to relocate and use the running rail, or the driving rail is unavoidably inclined, such as an arch bridge or a ramp bridge, the I beam can be fixed and used as the running rail. Second, in place of the cantilever for placing the main inspection, a simple hanging method may be used to run the main inspection off the main bridge.
